Pipe arranging mechanism with ball reciprocating lead screw for hydraulic operation machine

Abstract

The invention relates to a pipe arranging mechanism with a ball reciprocating lead screw for a hydraulic operation machine. The pipe arranging mechanism comprises a roller hub, a stroke sliding block, a supporting shaft, balls, a rolling sliding block, a transmission shaft, the reciprocating lead screw, a supporting arm, a sliding block sleeve and a limiting steel wire; the reciprocating lead screw is formed by combining a left-handed arc track and a right-handed arc track, and the balls rotate along with the tracks and further drive the sliding block sleeve to move forwards; and when the sliding block sleeve reaches the end point of the reciprocating lead screw, the two balls in a reversing groove move after reversing in the opposite directions, the rotating direction of the reciprocating lead screw is not changed, and the roller hub reciprocates left and right. The pipe arranging mechanism is ingenious in design and simple in structure, adopts the novel ball reciprocating lead screw, is small in friction resistance, high in sensitivity, stable in steering and free of vibration in the working process, effectively improves the quality and efficiency of gas extraction hole repairing, greatly prolongs the service life of equipment, and has good market prospects and development space compared with the prior art.

Description

technical field [0001] The invention relates to the technical field of a pipe arrangement device for a mine hydraulic operation machine, in particular to a pipe arrangement mechanism with a ball reciprocating screw for a hydraulic operation machine. Background technique [0002] Mine hydraulic operating machine is a kind of equipment used in underground coal mines to dredge the existing gas drainage holes. The working principle of the hydraulic working machine is as follows: use a mechanical mechanism to wind a flexible and windable stainless steel pipe on the drum in an orderly manner, and convert the linear motion of the steel pipe into a circular motion to realize the pipe collection action; The circular motion is converted into a linear motion and stretched into the gas extraction hole to realize the pipe delivery action. [0003] The spiral groove of the lead screw of the traditional reciprocating mechanism has a notch, and the strength at the intersection of the threa...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the problem that the spiral groove of the lead screw of the existing traditional reciprocating mechanism has a notch, the strength of the intersection of the threads at both ends of the notch is very weak, and the cooperation between the lead screw and the steering slider becomes unstable with the wear of the slider. The flexible steel pipe of the mechanism is distorted in transition, causing the slider to be often stuck with the lead screw, and the equipment has high failure rate. The structure is simple, using a new type of ball reciprocating screw, the frictional resistance is small during work, the sensitivity is high, the steering is stable, and there is no vibration, which can effectively improve the quality and efficiency of gas drainage hole repair and greatly increase the service life of the equipment.
