Belt conveyor efficient coal mining has become the key equipment. In the 1990s, Chinas coal belt conveyor to the long distance, with high-speed, large capacity, high-power direction of the development of the scientific research and the introduction, digestion and absorption of foreign advanced technology, to meet the basic development needs However, with foreign advanced than the belt conveyor there are still many gaps. In order to adapt to modern requirements for the development of coal mine construction, domestic belt conveyor design and manufacturing level, to be a qualitative leap.2 Domestic mine belt conveyor of the status quo More than 10 years, domestic coal belt conveyor from the SDJ, SSJ, STJ, DT series of stereotypes to the development of various special belt-lose Sending machine, such as steep belt conveyor complete sets of equipment, high yield and high efficiency face Gate retractable belt conveyors, steep, long distance products such as belt conveyors, and use dynamic analysis, intelligent control technology The key equipment of the theoretical research and product development, successfully developed a variety of soft starting and braking devices and programmable electronic control devices. But compared to models and advanced foreign and domestic conveyor models generally small, usually no more than speed with 4 m / s, generally use static design, high equipment costs, the reliability of running low. In addition, China has not yet formed components of the large-scale specialized production plants, design and manufacturing level needs to be raised.3 belt conveyors used models (1) fixed belt conveyor Fixed belt conveyor is the maximum use of coal as a model, mainly for the level of less than 18 inclination or the occasion. The largest main parameters are: capacity 1000 4500 t / h, distance 1000 8000 m, with speed 2. 5 5. 6m / s, bandwidth 2200 mm, the total power-driven 750 5550 kW. Domestic steel cord conveyor belt is now the highest use ST5000, the entire core band used PVG3150S, high-intensity mechanical joints still need to import. In order to reduce demand and reduce the intensity of tape drive size, usually middle or middle-driven linear friction unloading drive, and use of soft-start technology. Development is now nearly 10 kinds of soft-start, better to solve the major issues conveyer the start-up. Coal Branch of the Shanghai branch of the hospital, Zhao Jincheng Coal Mine Design and Development of the main manufacturing inclined belt conveyor main parameters: volume 2500 t / h, distance 1650 m, with speed 5. 6m / s, bandwidth 1600 mm, Drive 3 1850kW, Frequency Control. (2) retractable belt conveyor Retractable belt conveyor transport coal face for the main roadway transportation, the tail can advance with the coal face of contraction, the use of certificates with warehouses asylum redundant conveyor belt, compact, rack lightweight, easy accessibility, General use of the entire core zone, linked by mechanical joints, with the middle drive to meet larger capacity and greater distance requirements. 2005 Shenhua Group Corporation of God East mine with an annual output of 8 million t of high yield and high efficiency face supporting a homemade large retractable conveyor, the main parameters are: capacity 2500 t / h, distance 6000 m, with speed 4 m / s , The bandwidth of 1400 mm, transfer dip 3 , power 3 375 + 3 375kW, with the entire core PVG1800S. 2006 Shenhua Group Shendong company also equipped with a volume of Taiwans 4000 t / h, distance 6000 m, with speed 4 m / s, bandwidth 1600 mm, transfer dip 3 , power 3 560 + 3 560kW of China-made large-scale Scalable conveyor, and its technical performance has reached the international advanced level. (3) Inclination, under the belt conveyor Steep, downward belt conveyor is a commitment to the Shanghai branch of the state, July 5 key project, has been the State Planning Commission, State Science and Technology Commission and the Ministry of Finance issued by the major scientific and technological achievements Awards, the Ministry of coal a scientific and technological progress Prize and the promotion of the second prize. Up to now, have been put into use more than 300, of which transmission angle 26 28 of 5, transmission angle 30 35 of four. To meet the domestic coal use the angle on the urgency of the belt conveyor and widespread, a series designed to meet different needs, different bandwidth improvement and development of the Deep V-shaped double row roller group, the inclination to transfer the + 35 , under the transport plane angle also send up to - 28 . Big dip on the belt conveyor series can achieve soft-start and are contained, but also improve the braking performance. Conveyor bandwidth to 1600 mm; power to 3000 kW; distance to 1500 m above; belt speed to 4. 5m / s; volume increased to 2500 t / h; coal relaxed to allow water to 20 percent. (4) the level of turning corners belt conveyor belt conveyor level can be bypassed the building or unfavorable terrain, reduce or even no middle reproduced stations, concentrated power supply and control system, or plug the overflow of materials to reduce the risk and reduce dust Dust and noise, reduce unnecessary energy consumption. Chinas level of turning on the conveyor earlier study, in the 1990s, the successful trial production level of turning devices, successfully applied in the coal mine. 2001 in Shanghai Subway Construction, also used a standard retractable turning conveyor, the tunnel length of 2000 m, various corners, the minimum radius of curvature of the level of 360 m, the largest level of turning angle to 89 . The level of turning the belt conveyor, the United States, Germany and Austria are widely used. 1980 French captain a belt conveyor turning 11. 12km, elevation difference 577 m. Australia and the level of a mine belt conveyor turning radius of curvature 9 km, arc length 4 km, Power 3 700 kW (DC). (5) under the belt conveyor Long distance, large capacity, the steep downward belt conveyor use, can greatly reduce the mining area of the roadway project, reduce infrastructure costs and shorten the construction period, the motor running, but also to the power transmission grid, Have greater energy efficiency, is a good development prospects of a belt conveyor. However, as with high-speed, mobile and part of the rotational inertia of the great, great decline of production in the often slippery, rolling material, such as coaster accident, the transport plane sent to the key technology is the brake. Coal at home and abroad have used the brakes are: hydraulic brakes; hydraulic brakes; disc brakes. State, June 5 key scientific and technological projects with the hydraulic braking system installed under the belt conveyor, the drive is installed in the hydraulic braking system, brake to achieve the two-step, the first conveyor Speed reduced to one-third of the rated speed (by the speed 0. 1 0. 3m / s2 within the scope) and then by mechanical braking have the final gate. When mine accidents occur when a sudden power failure, can still achieve two brake. This downward belt conveyor to present the main parameters: inclination - 25 , volume 1500 t / h, with speed 3. 15m / s, distance 2000 m. Disc brakes are the most simple transport plane sent to the braking device, but because high-speed braking and a large quantity of heat produced sparks, braking only for an hour less than 10 times the number of low-speed braking. - Damping under the conveyor belt conveyor damper on the underside of the load transported, to offset the decline, and also has a wider application, the drive can be arranged on the lower end of the conveyor so that the motor Driver always maintain electrical functioning of the state. To improve the force of the conveyor belt, at the same time solve the transport conveyor belt conveyor retractable telescopic difficult problems. The inclination of not more than 16 transported under the condition can be applied at any time can be adjusted downward to prevent damping force, is very flexible; such a conveyor belt conveyor tension small, simple structure, can be achieved in long-distance And a series of advantages, but also a soft start and power balance, and other functions; security facilities, computer control, sensor monitoring, to meet the requirements of coal mine explosion-proof, the use of safe and reliable. Pingshuo, Huating, and other mining areas can be transported under the retractable belt conveyor, the main technical parameters are: capacity 2500 t / h, distance 3000 m, with speed 3. 15m / s, bandwidth 1200 1400 mm, transfer dip 3 , Power 3 375kW. (6) vertical belt conveyor Abroad from the late 1960s started to develop vertical belt conveyors, Germany Trellex Flexowell more than 50,000 Taiwan companies have products, distributed in over 90 countries and regions. May 1996, Liao Dai-vertical belt conveyors used in the United States, New York tunnel north of a reservoir built in the shaft, continuous vertical height of 208 m, Yun-speed 2. 42m / s.Under the right conditions the use of Liaodai belt conveyors, and upgrading and skip-belt conveyor with corrugated wall compared to the initial investment and operating costs can be significant savings. Vertical belt conveyors in Chinas coal mines is still blank. According to Chinas large coal mines, to meet the needs of upgrading the main shaft, the main parameters must be met volume 1200 t / h, upgrading a high degree of 400 m.Vertical conveyor upgrade the existing problems:1) conveyor belt a. flame retardant because of the special nature of the coal industry, steel cord belt has requested fire-retardant properties, must be consistent with industry standards MT45021995 Mine steel cord with flame-retardant, anti-static test methods and rules of judgement requirements.b. security to prevent the fault zone, is still vertical belt conveyor outstanding issues, blind expansion of safety factor, neither economic nor scientific. Abroad as a full computer tracking X-ray detection method to detect sulfide joint reliability of the link, my experience is still a law.c. cold Nien technology with corrugated wall of the base-band and the diaphragm is now linked through a secondary method of curing one, my cold Nien technology has yet to be improved. d. conveyor belt of economic price of about 5,000 U.S. dollars / m. If the conveyor belt all rely on imports, most coal companies are not acceptable.2) technical performance a. cleaning devices because of the conveyor system more complicated, cleaning effect is to address a key technology.b. convex arc of the material issues of materials left in the convex arc, in the role of inertia force and centrifugal force, the material can easily Paola, in particular with corrugated wall conveyor 0 30 , materials Paola phenomenon Even more serious. Liaodai laden belt conveyor also expected to throw. Shanghai Subway Construction in 2001 adopted a vertical belt conveyor, the main parameters: the rated capacity for 180 200 t / h, the level of the transport distance 8. 96m, vertical height 25 m, with speed 1. 25m / s, bandwidth 1000 mm, drive power 45 kW, the plane in September 2002 completed the installation commissioning, in normal use. (7) tubular belt conveyor Japan tubular belt conveyors, Ltd. (Japan PipeConveyor Co. L td.) In the late 1970s gradually formed a belt conveyor design theory and tubular products, in 32 countries patents, to 12 countries and regions Transfer of technology. According to incomplete statistics, produced a total of more than 1,000 Taiwan, the largest volume 3000 t / h, the largest pilots 3414 m, the largest transport angle 35 42 . In the early 1990s, Guoneishoutai tubular belt conveyor in Huainan Mining Bureau Xinzhuangzi coal mine ground transportation, traffic 600 t / h, distance 227. 65m, upgrading the total height 6. 52m, with speed 175 m / min, Clean Coal Wharf to bypass a central angle of 40. 15 , the 115 m radius of curvature of the vertical bend. The successful operation of its domestic bulk materials and created a new era of transportation. (8) pressure belt conveyor Pressure from the belt conveyor, closed-loop conveyor belt under the two components. Starting with the next load, the band also known as the coverage zone, mainly used to clamp materials, a gripping role to stop the decline of materials and rolling, and the materials and synchronous operation of the conveyor system. Pressure for increased transmission belt conveyor is designed to dip. 1954 in Germany there is pressure on the belt conveyor patents. 1979 U.S. mainland conveyor equipment company started to develop pressure belt conveyors, and in 1983 developed a pressure high inclined belt conveyor belt HAC (High2angle Conveyor) transport angle 30 60 , the largest transport capability 2900 t / h, rotating through the roller group loaded with pressure. , The mainland has produced more than 40 Taiwan HAC. From 1991 to 1994, Germanys MAN TAKPRFODERTECHN IK three companies developed a ship unloader for the pressure conveyor belt. The former Soviet Union and Japan and other countries have developed such a belt conveyor. Domestic product up to the pressure belt conveyor inclination 90 , the largest block of material to reach 300 mm. This conveyor because of their structural weaknesses and economic reasons, there is no application in the coal mine.4 Chinese mine belt conveyor direction of development (1) Large-scale and increase transport capacity In the next 10 years to increase transmission capacity to 3000 10000 t / h, with speed up to 5 8 m / s, retractable belt conveyor Transmission distance to reach 6000 m and above, the steel cord belt conveyor to be strong to 14000 m above, a single motor power to reach more than 1000 2500 kW, the conveyor belt tensile strength greater than 6000 N / mm (steel cord) and 3150 N / mm (The entire core). (2) improve the performance and reliability of components In addition to further improve and enhance the existing components of the performance and reliability, but also continue to study new technologies and the development of new components.(3) expand the functions of a multi-purpose machine Belt conveyor structure will make appropriate changes to expand Yun, Liu Yun-or two-way transportation, and other features, to use a machine to enable it to maximize economic efficiency. (4) for the development of models Chinas coal mine geological conditions vary significantly, in order to meet special requirements, should develop a special type belt conveyor, such as bending belt conveyors, steep or vertical conveyor, and so on. 5 mine belt conveyor development of the technology foresight (1) Dynamic Analysis the process of running the dynamic nature of the analysis, involving basic theory and modern advanced technology, comprehensive and high-tech. Germany, the United States, Japan and other countries in dynamic characteristics of an earlier study, and in practical engineering applications. Application of dynamic analysis technology to optimize the design of large belt conveyor, the minimum safety factor up to 4.8. Domestic conveyor without the dynamic characteristics of analysis, even if the use of a controlled launch devices, the safety factor also needs to take around 8. Crown land mines to be used in a large-scale use of the belt conveyor controlled devices activated, the safety factor must take 8.02, the only choice ST3500 strong steel cord conveyor belt. If the dynamic design, optical conveyor belt can be a cost-saving over 600 million, economic efficiency is considerable. Master dynamic analysis technology, will enable Chinas technological level of belt conveyors have a qualitative leap, as soon as possible in this area of work. (2) Controlled Start Launched a large belt conveyor speed up the process, the conveyor belt in viscoelastic deformation and a dynamic tension. When higher speed zone, the short-time start-up time, start acceleration and viscoelastic deformation on the conveyor belt is, the greater dynamic tension, will be seriously damaged when the conveyor system and other components. Controlled use of activated (also known as the soft-start) technology, will start at the beginning of the conveyor system is less than 10 percent decline in tension, the conveyor system does not guarantee skid. In recent years, at home and abroad have successfully developed various forms of soft-start devices:a. viscous liquid soft-start devices, such as Australias BOSS system, the United States of the CST;b. hydraulic-type soft-start devices, such as the governor of hydraulic coupling, after the Commission extended cavity fluid coupling; c. Electrical-soft-start devices, such as Frequency Control, SCR control SRM start; d. mechanical soft-start devices, such as BEST, Germany Rexroths auxiliary hydraulic motor revolving gear system. (3) transported under braking technology The belt conveyor in normal operation, with the rotor to achieve synchronous motor speed when the anti-torque to limit the speed of the conveyor system. But when downtime or power failure, due to loss of control, will cause material or roller coaster accident, the need for braking. Braking process is a slow process, the existence of the same conveyor belt deformation and the release of stored energy issues, such as improper control, in addition to a roller expected, the coaster accident, but also damaged the conveyor system and components, that may occur when a serious collapse of the conveyor belt . The belt conveyor of technical difficulties:1) the braking energy Brake absorb the mechanical energy into heat, the temperature increased rapidly, more than 150 have caused gas and coal dust explosion hazards. And the gates lining the friction coefficient decreased, the braking torque brake sharp decline, resulting in a coaster accident.2) the high requirements of the smooth braking Braking speed limit by 0. 1 0. 3m / s2 within the scope of, the brake for about 10 20 s. In order to maintain stability in the braking deceleration, braking torque request to load the size of the automatic adjustment.3) The power outage accident at the request quickly brake safety braking device must meet the technical requirements:a. braking by the speed must be limited to 0. 1 0. 3m / s2 scope;b. 10 per hour brake, contacts, in addition to not produce sparks, Various components may not be higher than the temperature MT820 - 1999 coal mine belt conveyor technical conditions set forth in temperature;c. the entire mining area also must ensure that the power outage to brake. Hydraulic braking devices, has been widely used in the coal mine. However, size, use a variety of energy (electricity, liquid, gas) complicated to operate, easy to accidents, raising the need to improve. Disc brakes small size, light weight, have saved a mechanical brake gate, operation and maintenance is simple, more suitable for use in the coal mine. But there are still key problems to be solved. (4) automatically tensioning technology In the early rally to ensure that the conveyor system to meet the minimum requirements of deflection, drum-driven trend towards the point and from the point of tension than the value should be set. Tension started with the requirements set tension ratio of 1.4 to 1.5, allowing fluctuations 10%; in the normal course of their work for the 0.9 to 1.1. Large belt conveyor tensioning device the technical requirements:1) automatically adjust tension As the conveyor belt tension can be adjusted automatically change to the starting point to trend-driven drum and Ben from the point of tension than to maintain the fixed value.2) fast response When the conveyor belt tension changes, tensioning device to restore responsiveness to the actual value of the sooner the better so that the conveyor belt tension stability and smooth operation, otherwise it may have vibration, or even resonance.3) there is no dead zone If the tail is the bottom of the high degree of vertical conveyor, the brake when the conveyor system may collapse and severe deformation, resulting in material Gunla, should be avoided.4）Gravity tensioning device by the coal mine because of space constraints, only for inclined belt conveyor. Winch with a combination of the fuel tank automatically tensioning device, the actual use that to achieve the requirement. The use of hydraulic winch automatically tensioning device, the response speed and reliability is much higher. Tensioning device installed in different positions, the necessary tension and the tension difference between a great trip. Domestic response to the current slow take-up devices, reliability is not high, to be further improved. (5) middle-driven technology Driven by the middle of the conveyor system can reduce the maximum tension, the conveyor system to reduce the intensity of demand, the unit drives small, not only handling, ease of installation, but it may also reduce the installation space, the widening of the roadway greatly reduced. There are two intermediate driver: linear friction drum-and-unloading. Line-by-friction conveyor belt conveyor to mastering the importation of power, not only greater investment, and Zhuangchai conveyor belt of heavy workload, the impact of face forward, thus stretching belt conveyor rollers are used for unloading Middle-driven. Middle-driven technology is the key to drive the load distribution and drive the boot sequence and the time interval. At present domestic and international use of hydraulic device to resolve the governor. (6) high-speed roller technology Transmission capacity in the same premise, with increased speed ratio increased bandwidth savings to investment in equipment costs. For security purposes, generally with speed control in 4 5 m / s. With increased speed, roller speed and spin resistance increased, decreased service life. Standards require that the roller speed can not exceed 600 r / min. Improve the quality of the roller reduce energy consumption, save costs and increase operational reliability of great significance. Roller bearing life depends largely on the performance, about roller bearings friction resistance of the rotating 1 / 4 to 1 / 8, Roller roller bearing commonly used 204,205 series. Bearing the performance of domestic and the United Kingdom, West Germany and other countries is basically the same.(7) tail since the rapid technology transfer High yield and high efficiency face to the tail retractable belt conveyor continuously under the conditions of the fast-moving. Now move abroad since the tail hydraulic drive configuration are tracked run institution, its power supply from the stent pumping station. China has introduced dozens of Taiwan, but also does not have its own design and manufacture of the rapid shift from the tail.

L td. )于上世纪70年代末逐步形成了管状带式输送机设计理论和系列产品,在32个国家获得专利,向12个国家和地区转让技术。据不完全统计,共生产1000多台,最大运量3000 t/h,最大机长3414m,最大运输倾角3542。90 年代初,国内首台管状带式输送机在淮南矿务局新庄孜矿地面运输原煤, 运量600 t/h, 运距227. 65m, 总提升高度6. 52m,带速175m /min,绕过精煤仓有一个圆心角为40. 15,曲率半径115m的垂直弯曲段。它的成功运行开创了国内散状物料运输的新纪元。 (8) 压带式输送机压带式输送机由上、下两条闭环输送带组成。下带起承载作用,上带又称为覆盖带,主要用
