specific Embodiment approach

[0025] Steel pipes and steel plates are selected according to the wire rope diameter, spacing and length. Drill 7 holes respectively on the steel plate 14, then at one end of the steel plate 14, be respectively fixed with three guide rods 12 by nut, flat washer, spring washer. The selected steel pipe is cut into two halves, and then welded on the steel plate 14. At the same time, the baffle plate 5 is welded on the "Z" elbow 1, and the "Z" elbow 1 and the steel plate 14 are connected and fixed by bolts 8, nuts 9, flat washers 10, and spring washers 11. Steel plate 14, half-section steel pipe 12 and " Z " font elbow 1 are now connected into a whole, and it is buckled on the wire rope, then cylinder 2 is fixed on baffle plate 5 places with bearing pin 6, cotter pin 7.

[0026] When the steel wire rope is lowered normally, the steel wire rope is lowered in the two half-cut steel pipes 12. Since the air inlet and outlet passages of the cylinder are closed, even if the steel wire ...

Abstract

A rope-binding prevention device for quickly changing a head rope of a mine hoist makes two Z-structural elbows correspond to each other, steel plates which are connected with one end of the rope-binding prevention device, a baffle which is connected with the other end of the rope-binding prevention device and a cylinder form a symmetrical frame structure, and at least more than two guide rods and corresponding half-sectional steel tubes which are arranged on the corresponding steel plates at intervals form a rope-binding prevention structure. The rope-binding prevention device has a simple structure, is convenient to operate, and provides guarantee for quickly and safely changing the head rope of the hoist.

Description

technical field [0001] The invention relates to a head rope replacement device for a hoist, in particular to a steel wire rope anti-squeeze device for quickly replacing the head rope using an old rope with a new rope in a multi-rope friction hoist. Background technique [0002] The existing multi-rope friction hoist in mines connects the new and old steel wire ropes through wire rope clamps when replacing the steel wire ropes, and uses the self-weight of the old ropes to drive the new ropes down to realize the replacement of the new and old steel wire ropes. The problem caused by the replacement method is: due to the high flexibility of the wire rope, during the lowering process, the load is not uniform, the speed is not synchronized, and the energy accumulated inside the wire rope is released, resulting in irregular swing of the wire rope, which is easy to cause the rope phenomenon, and even the wire rope in the During the swing process, the wellbore equipment will be damag...
