外文资料Winch, a light small lifting device that uses a reel to Twine a wire rope or a chain to lift or pull a heavy object, also known as a winch hoist. The winch can be used alone. It can also be used as a component of lifting, road building, and mine lifting. It is widely used because of its simple operation, large winding capacity, and convenient displacement. Mainly used in construction, water Conservancy projects, forestry, mines, docks and other materials lifting or dragging.Winch, also known as winch, is a light, small lifting device(see crane) that uses a reel to wrap a wire rope or chain to lift or pull a heavy object.The winch system mainly includes: main drum assembly, winch frame and cover assembly, corner transmission box assembly, Turntable transmission device, main drum brake system, main brake cooling circulation system, water brake, water brake water circulation system, winch power input and output protective cover, car anti-collision device, etc. Composition. The winch parts of the drill machine are arranged on the power winch pry seat, which is compact, convenient for installation and disassembly.The winch has the following characteristics: high versatility, compact structure, small size, light weight, great importance, convenient use and transfer, and is widely used in the lifting or dragging of materials such as buildings, water Conservancy projects, forestry, mines, and docks. It can also be used as a supporting equipment for modern electronic control automatic operating lines. There are 0.5 tons to 350 tons, divided into fast and slow. Among them, more than 20 tons are large-tonnage winches. The winches can be used alone, and they can also be used as components in machinery such as lifting, road building, and mine lifting. They are widely used because of their simple operation, large winding capacity, and convenient displacement. The main technical indicators of winch include rated load, support load, rope speed, and rope capacity.The main purpose of the winch: First, as a lifting equipment, it is used for mine lifting, drilling and suspension(lifting) drilling equipment facilities, that is, lifting ore, waste(stone) stones, lifting personnel, decentralized materials, tools and equipment along the wellbore; The second is as a transportation equipment, used for underground dispatch and transportation of ore(mining vehicles), mining dredge(slag) or filling, removal of pillars and so on.The winch is divided into pneumatic, manual, electric and hydraulic categories according to power. From the purpose classification can be divided into building winches and marine winches.According to the functions of the winch can be divided into: ship winch, engineering winch, mine winch, cable winch and so on.Divided into single drum and double drum in the form of a reel.According to the distribution form of the reel, it is divided into parallel double rolls and front and rear double rolls. Special types of winches are: frequency conversion winch, double-barrel winch, handbrake lever double brake winch, with limiter winch, electric winch, electric handbrake clutch winch, large double barrel double brake winch, large outer gear winch, large hydraulic winch, large outer winch Gear belt tether winch, double traction wheel winch, large hydraulic double-barrel double brake winch, frequency conversion belt limiter winch.The JM-14B slow winch is the main type of auxiliary transport winch used under the Xingtai mine in Suizhong Energy. In the actual production of the winch in the underground, there are often a series of problems such as the breaking of the rotors and the frequent loosening of the winch fixing device. This paper optimizes and designs the parts of the winch according to the underground production conditions of Zhongnengyuanxingtaikuang and the characteristics of the winch itself. It can adapt to the underground production requirements of Xingtai Mine. To reduce the damage rate of the winch and improve its productivity.The coal mining machine and part of the bracket recovered from the 3301 working surface must be lifted to the well by the auxiliary well slow winch. In order to ensure the safety improvement, the tension strength of the slow winch wire rope is calculated, the necessity of replacing the wire rope and the preparation work before the lifting are described, and the concrete implementation process of the slow winch lifting coal mining machine is introduced. Some things that need attention in the process of promotion are put forward.Use protocolThe winch must be set up according to the specifications. The net height of its specifications is not less than 2.0 meters and the net depth is 2.0 meters. According to the actual situation of the roadway, the roadway along the air delivery lane is determined in order not to affect the safety operation.2, winch construction as far as possible by the use of wind pickaxe excavation, according to the different support type of the tunnel can be used wooden shed or workword steel shed support. When the roof is intact, anchor net support is used, and when the roof is broken, shelter support is used.3, 11.4 KW small winch foundation must be cast, its basic specification is 1.0 1.0 1.0 meters. The ratio of cement, sand, and stone(melon seeds) in the concrete is 1:2:2; The water ash ratio is 0.4.4, the winch adopts the shed support, to be carried out from the outside to the inside, the shed and the shed must be connected with a support or pull rod into a whole, waist, help to close back. The shed distance does not exceed 0.7 meters. When using anchor network support, the spacing of the anchor rod is 800 800mm.The winch motor shall be installed on the inner side of the small winch socket, and the operating space distance shall not be less than 0.8 meters; Operation button on the shelf, the switch is arranged neatly and must not interfere with the operation of personnel.6, other in accordance with the relevant provisions in the operating procedures.Adjustment and maintenance of winchesAdjustment of winchesAfter the winch is installed, it must be checked and adjusted.1, open gear transmission, the tooth side gap is 0.42 mm, its contact area along the tooth height is not less than 40 %, the length of the tooth is not less than 50 %.2, check whether the working brake transmission system is flexible and reliable, and adjust the clearance between the brake tile and the brake wheel does not exceed 0.7-0 .8 mm.3, check whether the safety brake transmission system is flexible and reliable, and adjust the clearance between the brake tile and the brake wheel does not exceed 1.5 mm.4, check whether the control of the working brake and the safety brake is interlocked with the main motor, that is, start the main motor working brake loose, stop the main motor working brake brake, and only the safety brake loose can start the main motor.Lubrication of folding winch1, the reducer is lubricated with winter gear oil or saturated cylinder oil, and its oil surface should ensure that the worm is immersed in the oil. The reducer is changed once a year.The bearing of the output shaft of the spindle bearing and the reducer shall be replaced or supplemented regularly with the No. 4 calcium-based lubricating grease, and the oil shall be changed every two years.3, the open gear should be lubricated before each drive.The rest of the lubricating parts should be lubricated before each drive, especially the thrust ring between the two gears on the speed reducer output shaft and the axle sleeve of the moving gear should be lubricated.Trial operation of folding winchAfter the winch is installed, it can be lubricated and lubricated at each lubrication site after being checked and adjusted. It can be tested on empty, and the load operation is carried out after winding, and it is gradually loaded to the rated load. At the standard voltage, the current does not exceed the rated value, and the motor, speed reducer, and other parts do not heat up. For example, the weak link of the gyro winch is the spherical worm vice drive, and the main drive of the gyro winch adopts the worm vice drive. This is because the worm vice drive ratio is large and it has self-locking, so its transmission efficiency is low. Generally only 0. From 4 to 0.45, the total transmission efficiency of the rewind winch is lower. Rope speed is slow, and the speed of the return train is the same as the working traction speed. Whether the winch is used to top the column or to carry equipment, the efficiency is too low. With the development of coal mining mechanization, the frequent relocation of comprehensive mining equipment, and due to the transfer of the winch back column, the long working time occupies more manpower, so such winch should be set up fast return rope.中文译文绞车，用卷筒缠绕钢丝绳或链条提升或牵引重物的轻小型起重设备，又称卷扬机。绞车是可单独使用，也可作起重、筑路和矿井提升等机械中的组成部件，因操作简单、绕绳量大、移置方便而广泛应用。主要运用于建筑、水利工程、林业、矿山、码头等的物料升降或平拖。绞车(winch)又称为卷扬机，是用卷筒缠绕钢丝绳或链条以提升或牵引重物的轻小型起重设备(见起重机械)。绞车系统主要包括:主滚筒总成、绞车架及护罩总成、角传动箱总成、转盘传动装置、主滚筒刹车系统、主刹车冷却循环系统、水刹车、水刹车水循环系统、绞车动力输入输出护罩、天车防碰装置等所组成。钻修机绞车部件设置在动力绞车撬座上，结构紧凑、安装、拆卸方便。绞车具有以下特点:通用性高、结构紧凑、体积小、重量轻、起重大、使用转移方便，被广泛应用于建筑、水利工程、林业、矿山、码头等的物料升降或平拖，还可作现代化电控自动作业线的配套设备。有0.5吨350吨，分为快速和慢速两种。其中高于20吨的为大吨位绞车,绞车可以单独使用，也可作为起重、筑路和矿井提升等机械中的组成部件，因操作简单、绕绳量大、移置方便而广泛应用。绞车主要技术指标有额定负载、支持负载、绳速、容绳量等。绞车主要用途:一是作为提升设备，用于矿井提升、凿井提升及悬吊(升降)凿井设备设施，即沿井筒提升矿石、废(矸)石、升降人员、下放材料、工具和设备等;二是作为运搬设备，用于井下调度运输矿石(矿车)，采场耙矿(渣)或充填、撤除立柱等。绞车按照动力分为气动、手动、电动、液压三类。从用途上分类可分为建筑用绞车和船用绞车。绞车按照功能可以分为:船用绞车、工程绞车、矿用绞车、电缆绞车等等。按照卷筒形式分为单卷筒和双卷筒。按照卷筒分布形式有分为并列双卷筒和前后双卷筒。特殊型号的绞车有:变频绞车 、 双筒绞车 、手刹杠杆式双制动绞车、带限位器绞车、电控绞车、电控手刹离合绞车、大型双筒双制动绞车、大型外齿轮绞车、大型液压式绞车、大型外齿轮带排绳器绞车、双曳引轮绞车、 大型液压双筒双制动绞车、变频带限位器绳槽绞车。JM-14B型慢速绞车是冀中能源邢台矿井下所使用的主力型辅助运输绞车。该绞车在井下实际生产中经常出现对轮销子折断,以及绞车固定装置经常松动等一系列的问题,本文根据冀中能源邢台矿自身的井下生产条件以及该绞车本身结构的特点对该绞车各部位进行优化与设计。使其能够更加适应邢台矿的井下生产要求。达到降低该绞车的损坏率,提高生效率的目的。3301工作面回收的采煤机和部分支架要由副井慢速绞车提升上井。为保证安全提升,对慢速绞车钢丝绳进行了抗拉强度的计算,阐述了更换钢丝绳的必要性和提升前的准备工作,介绍了慢速绞车提升采煤机的具体实施过程,
