多绳摩擦提升机的钢丝绳张力平衡装置(国外英文资料) Multi-rope friction lift wire rope tension balance device Multi rope friction hoist in normal operation process, due to the rope groove machining diameter deviation, deviation of the length of the wire rope hanging and rigidity deviation between the steel wire rope, the influence of such factors causing the cable that uneven. Mining machinery and equipment in order to eliminate the imbalance problems of wire rope in use, guarantee the balance between the lifting rope tension, on the one hand, the action could be taken to: 1) set the tension balance device at the junction of the container and wire rope 2) adjust the tension in the wire regularly Adjust the length of the wire regularly to make it even. The common regulator for adjusting the length of wire rope has the following: (1) pad regulator. The adjustment instrument increases or shortens the length of the wire rope by reducing or increasing the amount of the block. This kind of adjustable rope is simpler and is used both at home and abroad. The disadvantage of mining machinery is that the adjustment length is only a multiple of the thickness of the wedge, so the adjustment of the rope is not ideal. Next is the mat is rust to die, increase, reduce the block is more leisurely and difficult. (2) screw regulator. The mechanism of the screw regulator is the artificial rotary screw, which produces the relative rotation of the nut, and adjusts the degree of the wire rope in a certain way. Mining machinery equipment its advantage is simple structure, small height, the rope exercise measure on block type, convenient and can be adjusted under the terminal load of steel wire rope; The disadvantage is that the screw is likely to be unmoved because of the corrosion of the cow. (3) the screw hydraulic line device. Screw hydraulic line and wedge-shaped rope with helical hydraulic line suspension. Call rope spiral hydraulic device is used to adjust the main function of wire rope in installing and run
