Problems solved by technology

At present, the method adopted in coal mines when cutting old ropes is that multiple operators use brown ropes to pull the steel wire ropes to one side to prevent the steel wire rope from rotating and hurting people when cutting old ropes, but the huge internal torque may break the brown ropes. Therefore, the efficiency of this method is relatively low, its reliability and safety are not ideal enough, and the personal safety of operators cannot be effectively guaranteed.

Embodiment Construction

[0014] The technical scheme of a kind of steel wire rope fast replacement torsion release device provided by the present invention is further described below in conjunction with the accompanying drawings:

[0015] Such as figure 1 and figure 2 As shown, the concrete technical scheme of implementing a kind of steel wire rope fast replacement torque release device of the present invention is to be respectively provided with an annular groove inside the middle part of the 4 holes of the left card 1 and the right card 2, respectively set in the grooves There are three cylindrical rollers 9 at an angle of 60°, and hexagon head bolts 11 are provided to connect the cylindrical rollers 9 with the left board 1 and the right board 2 respectively in the form of penetration. The inner side of the hole of the right plate card 2 is respectively provided with a left half sleeve 10 and a right half sleeve 15. Wherein the cylindrical roller 9 has reduced the frictional force generated by th...

Abstract

A quick-change torsion release device for steel wire ropes is provided with an annular groove on the inner side of the middle of the hole of the left board and the right board respectively, and three cylindrical rollers at an angle of 60° are respectively arranged in the grooves, and are inserted into the There are hex head bolts connecting the cylindrical roller with the left board and the right board, and the left half sleeve and the right half sleeve are respectively arranged inside the holes of the left board and the right board. The overall structure of the device is simple, easy to operate and disassemble; when the wire rope of the coal mine hoist is quickly replaced, the torsion of the wire rope is safely and reliably released completely, which solves the problem of endangering personal safety and equipment damage when the torsion release is released during the replacement of the wire rope.

Description

technical field [0001] The invention relates to a wire rope replacement device for a coal mine hoist, in particular to a wire rope quick replacement torsion release device for the first rope replacement device of a multi-rope friction hoist in a coal mine when the wire rope releases torque when the old rope is cut. Background technique [0002] Wire rope is an important part of mine hoisting equipment and plays a very important role in the normal operation of mine hoisting equipment. The quality of wire rope not only has a direct impact on coal mine production, but also relates to the personal safety of miners. The steel wire rope has a certain service life. If the wire rope has broken wires, reduced diameter and corrosion, etc., and the service life exceeds the relevant regulations, it must be replaced in time to prevent accidents. [0003] When the first rope quick change device of the multi-rope friction hoist in the coal mine cuts off the old rope, there is a considerab...
