Self-traveling equipment train used for fully mechanized coal mining face

Abstract

The invention discloses a self-traveling equipment train used for a fully mechanized coal mining face. The self-traveling equipment train mainly comprises two flat cars, a transverse shift device, support devices, connecting frames and a hydraulic control system, wherein the flat cars are lapped in series front and back; the transverse shift device is connected between the two flat cars, and is used for driving the two flat cars to move front and back; the support devices are vertically fixed on each flat car by the corresponding connecting frame, and are capable of supporting the flat car to keep fixed on site; the hydraulic control system is used for controlling the sequential action of the transverse shift device and the support devices. The self-traveling equipment train used for the fully mechanized coal mining face is simple in structure and easy to operate and control, the alternate movement and the steady support effect of the two flat cars are realized by the stretch and the shrinkage of the transverse shift hydraulic cylinder and a piston cylinder, the stability of the self-traveling equipment train on the fully mechanized coal mining face with a large dip angle is improved, the occurrence of self-slippage phenomenon is prevented, the mobility of the train is controlled at any time according to needs, and the maneuvering characteristic is improved.

Description

Technical field [0001] The present invention belongs to the field of coal mine mining equipment, which involves a self -transfer train of a comprehensive mining work surface equipment. Background technique [0002] In the integrated mechanized coal mining system, the equipment trains are in the upper and lower levels. The efficiency of the equipment and train of the equipment is low, poor safety efficiency, and poor operating conditions. It is recognized by domestic and foreign coal mine companies.Especially in Xinjiang, due to the geological conditions and coal seam structures of Xinjiang, it is difficult to start the equipment of the equipment during the return period, and it is difficult to move the equipment trains. This phenomenon is mainly caused by large -scale coal seams.The major international coal production countries have basically not proposed an effective solution to the moving equipment trains. Only a few countries have conducted some test -based research on equipme...

AI Technical Summary

Problems solved by technology

[0004] 1) The fully mechanized mining face is transported by traditional rail winch and wire rope traction equipment trains. This transportation method has the disadvantages of large investment in equipment, easy running, falling off the road, wasting a lot of manpower and material resources, and there are serious safety hazards in the process of moving ;

[0005] 2) Usually, the equipment train is pulled by the return column winch, which is easy to cause a sports car and has poor maneuverability. It cannot move at any time, and the moving speed is slow. There is a self-slip phenomenon of the train when walking on a slope above 7°, and the overall stability is poor, which brings The corresponding transportation problems have been solved, which has caused hidden dangers to production safety
