VI well above the old string with new string, specific methods are as follows: Cans will be parked in the south tank top level VI and the location of wells； VI in wells adjacent to the north can take the work platform, the new rope through the window well wall Tabei VI and four driven wheels, and four cans of the old North ropes long, respectively, 3m, slightly small bundled, tied for the new Departments (new rope in the old side). Specific binding is as follows； first one 3m long hemp rope around 1m intensive new rope, hemp rope and then the remaining entangled in the original location of the new justice will be the new and old ropes tied together, the hemp rope tied after water immersion (tied up a litter wet before the small), At the same time, decentralization of the South can tank the new string, using the same method with the above-mentioned first since the beginning of each new interval 10m rope firmly tied up with the old rope, wire rope when the new tank to the South side, and well above the first VI flush steel stops, can work to dismantle the North well head platform. In the four-storey tower platform wells, using a dedicated card in the North side of the tank 4 prison in order to prevent the new rope to escape, and then cut off all of the hemp rope tied to the new and the old rope separately. Five-storey tower in the wells, the South side of the new cans with rope sling jail card, with four new road will be the appropriate height of lifting rope to the main drive roller can not rotate a new justice prevail, then the human will be four to the second floor of the new platform. 3 (2) The South can head the new wire rope hook. The South Side can wedged-shaped with four back-up devices to connect firmly hanging； to the old and new wire rope hanging device of the alignment, the use of hemp rope tied firmly. The second floor on the first pressure hydraulic pump with the South can automatically balance the fuel tank connecting pipe even after the good, the total cut-off to open the door a little to the fuel tank of the oil pump to suppress all Add, and then South automatic hydraulic hook Unicom balance tube to remove the fuel tank and on a designated location. Finally, the slow decentralization of the Southern cage hook, a new extra rope taut. (3) Shaft with a new rope. Long sling to remove five boards and four sub-board anti-back channeling, and four new chairs were placed on the corresponding slot on the west side of the old rope suitable location. Three-storey tower in the well platform, the South side of the new cans, the old rope a long board with a daughter card to pay in jail, and then in the long upper and lower sun-board 4 of the card to pay a small board. Hoist speed with low-frequency southern decentralization cans, at the same time, four ropes to the corresponding roller speed put to justice； At this point, three-tiered platform in the wells south tower tank side, since the first sub-board pay long bundled together from every 6m hemp rope (the same method mentioned above) and timely water immersion, respectively, at intervals of 50m to pay a small four-card sub board. When the second floor of the South four wedge-shaped cage hook hanging device. (4) The replacement of the South four wedge-shaped cage hook 4 hanging device. Well fist of all in the four-storey tower, the south and east-west direction of wire rope hook emission No.2 2o I-beam, four in its place above, and the South Hook old jail 4. by the shearer two 20t chain hoist with hook cage will Northern； lot with two hoist, lifting cans southern appropriate height, the replacement of the eastern side of the first two hanging devices, specific methods are: using 12.5mm rope hoist it would be cape and hydraulic telescopic self-balancing device body, followed by removal of the eastern side of the two wedge-shaped hanging type linked to the original device. Then, the first installation of the new East from the second wedge-shaped only hanging device, and then install the East from the first wedge-shaped hanging new home. replacement of the west side of the two wedge-shaped only hanging device, the replacement of finished hemp rope to use old and new wire rope hanging device firmly bundled counterpart. (5) In the second floor of the new wire rope cut-off platform, and a new wedge-shaped hanging rope and back-up device connected. (6) The replacement of the North hook hanging cage four wedge-shaped device. first pump pressure on the second floor of the North can fuel tank of the hydraulic self-balancing good even after the connecting pipe, the total cut-off to open the door a little, the fuel tanks of the oil pump to suppress all Add , and then North hook automatic hydraulic Unicom balance tube to remove the fuel tank, put away , pull two hooks 20t hoist cage will Northern appropriate high level of lifting, running from east to west in accordance with the gradual replacement of the end, 5 removed the old rope, and to dismantle working platforms. (7) Rope groove back. Four-storey tower in the well child with a long board to the north side of the hook 4 new and 4 old rope firmly. 12.5mm wire with cap and traffic will be the new and old rope hanging to the old and new wire rope led from the round, starting from the east, followed by the old rope from the leading wheels, tank-oriented round of rope out, and Add new rope groove in turn, led on the old rope round or rounds of pad-oriented on the (eastern side of the rope groove). Wells to remove board tower with four sub. (8) Recovery of the old rope. At the same time, North hook hanging loose cage of two20t hoist will be closed until the new cage force of wire rope, lifting appliances, dismantled, and the old four corresponding bundled with the new wire rope. Removal of underground organizations in Southern constructors cage hook lifting equipment and work platforms. Starting distance from the winch, and a I-beam removal of. After checking no problem to begin with low-frequency North hook cage decentralization, with the old rope through human well-oriented round of the four 1:3 corresponding rope drag on the roller, at the same time, new and old ropes and Negro In addition. When the South Hook 1:3 wells can reach the top of the appropriate parking location, using gas cutting steel wire rope in the old cut-off above the first hook, and drag the working area without prejudice. Well 1:3 in the appropriate location. North side of the tank 4 old rope cut by gas cutting, and then to the north side of the tank 4 with 6 the corresponding old new rope tied solid and well-head side of the South can take temporary work platform. Starting winch, hook cage south decentralization, while the remaining out of the old rope, after the removal of temporary work platform. (9) Transfer to justice, after all, no problem, winch test run, commissioning a variety of protection. 3、 Construction Notes (1) Signal is the key to the construction, we must set up the command center, put to justice and enhancing the signal to separate the signals, at least to prepare two sets of signals, and winch drivers, put ropes and other staff to participate in the construction clearly. (2) The length of board and hand chain hoist, and early tests, such as appliances, and construction must be firmly card. (3) In the interception of a new rope should be based on precise calculation of the amount in advance from a good length of rope, new rope can not be truncated, otherwise, would be lost by the wayside, causing a greater loss. (4) Use of this method with the traditional solid car with rope method, the construction time is short. Cao coal for the use of this method were used rope 19.5h, save time 1/3 polyunsaturated. 4、 Conclusion (1) Of this method with the traditional solid car with rope method, the 7 construction time is short, Cao coal for the use of this method were used rope 19.5h, save time 1/3 polyunsaturated. (2) Low-cost construction. This method saves the cost of steady rental cars, a construction can save about 25,000 yuan. (3) High degree of safety, reduce labor intensity. Minimization of this method in the construction of the shaft to raise the safety factor, without a fixed rope roller, just the direction of the rope can be placed, the short preparation time. 1 多绳摩擦式提升机换绳新工艺 多绳摩擦式提升机在更换钢丝绳时，通常使用四部固定稳车旧绳带新绳，工艺复杂，施工人员多在井口和井筒作业，危险性较大，而且矿井停产时间长，因此如何在更换此类提升机主钢绳中更加安全、省时，一直是人们研究的目标。 1、 施工准备 （ 1）提前对备 用楔形掉挂装置进行探伤，对新的备份钢丝绳进行测试，符合煤矿安全规程的 第 402条相关规定，测量尺寸，截成四段分别缠在四只绳滚上，按捻向要求防御井架的北侧，并固定好。 （ 2）在井架北钩横梁合适位置固定四个导向轮，以便钢丝绳能够顺利运动。 （ 3）调整自动平整油缸杠杆的伸缩量，首先使南钩自动平衡油缸杠杆的伸缩量一致后，关闭南钩个自动平衡油缸的分截止阀，运行一天后，再量取南北两钩个油缸杠杆的伸缩量，并记录好，作为截绳的依据。 （ 4）准备好卡绳用的长、短板卡，长板卡需要 3 副，段板卡需要8副。 （ 5）准备好充足的照明和可靠地信号设施以及棕绳、铁丝、木板、工字钢以及常用工具等，并检查是否合 格。 2、 施工步骤 （ 1）自上而下清扫平台、井架及井筒，拆除滚筒护板。井口以上 2 用旧绳带新绳，具体方法为： 将南罐停在灌顶与井口平的位置；在井口北罐侧搭工作平台，将新钢丝绳穿过井塔北墙窗及四个导向轮，并与北罐四根旧绳分别用长 3m 长小棕绳捆绑在一起，新绳头处连续捆绑三道（新绳在旧绳西侧）。具体捆绑方法是：先用 3m 长麻绳的其中 1m密集缠绕新绳，再用剩余的麻绳在原来缠绕新绳的位置将新、旧绳捆绑在一起，绑完后用水将麻绳浸透（捆绑前小棕绳稍湿）。 下放南罐同时放新绳，用与上述同样的方法自第一道棕绳七每间隔 10m将新绳 与旧绳捆绑牢固，当新钢丝绳绳头到达南罐侧，并与井口以上第一道钢梁平齐时停车，拆除井口北罐工作平台。 在井塔四层平台上，用专用板卡在北罐侧将四根绳卡牢，以防止新绳回窜，然后。割掉所有捆绑的麻绳，使新绳与旧绳分开。在井塔五层，将南罐侧新绳用吊绳卡卡牢，用行车将四根新绳吊起适当高度，以主滚筒不能带动新绳转动为准，然后用人力蒋四根新绳托至二层平台。 （ 2）南罐新钢丝绳上钩头。将南罐侧四根绳头分别与四个备用楔形吊挂装置连接牢固：将新、旧钢丝绳的吊挂装置对齐后，用麻绳牢固的捆绑在一起。先将二层上的打压泵与南罐液 压自动平衡油缸联通管拆除，并放到一指定地点。 缓慢下放南钩罐笼，拉紧多余的新绳。 （ 3）井筒新钢丝绳子。 拆除五层吊绳的长板卡子及四层防回窜板卡，并将四根新绳分别放在与其对应的旧钢丝绳槽西侧合适位置。在井塔三层平台上，将南罐侧新、旧钢丝绳用一副长板卡卡牢，然后在长板卡的上下个卡 4副小板卡。 提升机用低频速度下放南罐，同时，四个绳滚子以相应的速度放绳；此时，在井塔三层平台南罐侧，自第一副长板子起每隔 6m 捆绑一道麻绳（方法同上述）并及时浇水 3 浸透，每隔 50m分别卡 4副小板卡子。当北罐接近井口二层平台时停车， 带绳结束。 （ 4）更换南钩罐笼四个楔形吊挂装置。首先在井塔四层，南钩钢丝绳东西方向并排放两根 20号工字钢，在其上面放四个卡绳器，并将南钩四根旧绳卡牢。用两只 10T葫芦配合采煤
