Description

Technical Field

[0001] The utility model belongs to the technical field of underground coal mining, in particular to a telescopic frame and conveying equipment. Background Art

[0002] In underground coal mining operations, the coal mined by the coal mining machine is continuously transported to the chute belt conveyor connected behind it through the working face conveyor, crusher, bridge-type transfer machine and belt conveyor self-moving tail. The belt conveyor self-moving tail is a supporting equipment for tunnel transportation of the fully mechanized mining working face. It is very important as an intermediate connection device between the belt conveyor and the bridge-type transfer machine. It should be suitable for high production and high efficiency and meet the needs of rapid advancement. At the same time, it has the functions of belt deviation adjustment, height adjustment, transfer machine push direction correction and self-advancement to ensure the smooth and connected chute transfer.

[0003] With the comprehensive development of coal mining, the speed of coal mining is very fast. The original self-moving tail of the belt conveyor can no longer meet the demand in terms of travel. The self-moving tail needs to move forward along the coal mining direction, which requires the removal of the longitudinal beams, parallel frames, rollers, etc. of the original chute belt conveyor, resulting in reduced coal mining efficiency. The root cause of this problem is that the single-time advancement stroke of the self-moving tail is not enough to meet the requirements of coal mining speed. The overall structure of the tail equipment is rigid, and it is impossible to increase the stroke through simple modification, so it is necessary to improve it. Utility Model Content
