Steel wire rope guide device for tunnel construction winch

Abstract

A steel wire rope guide device for a tunnel construction winch comprises a guide wheel, control plates, a guide wheel shaft, a steel wire rope, a rack, a first telescopic rod, a second telescopic rod, a third telescopic rod, a fourth telescopic rod, guide rail blocks, sliding blocks, short rods, long rods, a supporting panel, a containing plate and a guide sleeve. Each control plate comprises a flat plate fitting part, an inclined part and a stress part. The supporting panel is composed of a left plate and a right plate, and the left plate and the right plate each comprise an extension part.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a wire rope guiding device for a tunnel construction winch. Background technique [0002] The winch is an indispensable tool in the tunnel construction process. It runs on a fixed track through wire rope traction. During operation, in order to ensure that the drum can be retracted or released smoothly, a guide mechanism is often required between the drum and the winch; however, in In the specific actual production practice, there are the following problems: [0003] 1. In the prior art, since the pulling direction of the steel wire rope is often inconsistent with the guidance of the guiding mechanism, friction occurs between the steel wire rope and the guiding mechanism, causing wear of the steel wire rope and increasing power consumption of the equipment. [0004] 2. In the prior art, due to the harsh operating environment of the winch, the pulling direction of the ...

AI Technical Summary

Problems solved by technology

[0003]1. In the prior art, since the pulling direction of the steel wire rope is often inconsistent with the guidance of the guide mechanism, friction occurs between the wire rope and the guide mechanism, causing wear of the wire rope and increasing power consumption of the equipment

[0004]2. Due to the harsh operating environment of the winch in the prior art, the pulling direction of the steel wire rope is extremely unstable during the pulling and unwinding process of the drum, which causes the guide mechanism to vibrate accordingly , then it may cause the wire rope to break away from the guide mechanism and cause a safety accident

[0005]3. In the prior art, there is a solution of buffering by telescopic rods, but this kind of buffering does not consider the buffering direction, and it is generally linear buffering

[0006]4. The flat or curved panels in the prior art generally have a single function and cannot realize more functions

[0007] 5. The guiding mechanism of the prior art, that is, the guiding wheel, in actual application, due to different working conditions, such as the difference in the number, diameter and weight of the ropes, there are The need to adjust the size of the guide wheels, however, a single fixing frame cannot meet the needs of accommodating guide wheels of different sizes
