Mining automatically-moving equipment train capable of stepping forward along roadway

Abstract

The invention belongs to the technical field of designing and manufacturing of underground auxiliary transportation devices used under coal mines and provides a mining automatically-moving equipment train capable of stepping forward along a roadway to achieve underground transportation along roadways of the coal mines. The mining automatically-moving equipment train capable of stepping forward along the roadway comprises a front anchoring and pulling device, a rear anchoring and pulling device, a flat car and an expansion pipe cable bearing system, wherein the front anchoring and pulling device and the rear anchoring and pulling device are erected on an anchoring frame guide rail, the flat car is erected on a flat car guide rail, a forward-pushing jack is arranged at the front end of the front anchoring and pulling device, the rear end of the front anchoring and pulling device is connected with the flat car through a backward-pushing jack, the front end of the rear anchoring and pulling device is connected with the flat car through a pushing jack, and the rear end of the rear anchoring and pulling device is connected with the expansion pipe cable bearing system through a connecting pipe. The mining automatically-moving equipment train capable of stepping forward along the roadway has the advantages of being flexible, convenient to use and the like; equipment movement efficiency and safety are improved, equipment movement time is shortened, frequent rail laying and pulling transportation are avoided for workers, the labor intensity of the workers is relieved, and it can be guaranteed that the equipment train can travel on a ramp with the gradient being +/- 10 degrees.

Description

technical field [0001] The invention belongs to the technical field of design and manufacture of underground auxiliary transportation equipment in coal mines, and in particular relates to a coal mine self-moving equipment train along a trough. Background technique [0002] For the self-moving mode of equipment trains in the fully mechanized mining face, there are generally complex procedures, low efficiency, and poor maneuverability during the movement. During the pulling process, accidents such as sports cars, off-tracks, and scratches are prone to occur, and there are great potential safety hazards. Management pressure is high. [0003] At present, there are mainly two types of trains for pulling equipment: [0004] (1) Winch-type steel wire rope traction with corner column, this kind of traction method has complicated procedures when moving, the wire rope is easy to break, and it is easy to cause a sports car, and the moving speed is slow. There is a self-slipping phenom...

AI Technical Summary

Problems solved by technology

[0006] 1) This method of movement has relatively high requirements on the floor, which must be flat and cannot walk on slopes above 7°;

[0007] 2) When moving, it cannot drive the equipment train to move as a whole, it needs to move in sections, the moving speed is slow and the efficiency is low;

[0008] 3) When the equipment train carries heavy equipment, the lifting cylinder cannot lift the equipment, but can only move light equipment, and the overall stability is poor
