Belt storage device of underground coal mine bet conveyor

Abstract

The invention provides a belt storage device of an underground coal mine bet conveyor and relates to underground coal mine mining and conveying equipment. The belt storage device comprises a belt storage device frame (1), a front direction changing roller (2) and a tensioning roller (3). The belt storage device frame (1) is provided with two longitudinal side rails (6). The two sides of a tensioning trolley frame (5) are each provided with a groove (7) used for being matched with the corresponding longitudinal side rail (6). The grooves (7) are clamped to the longitudinal side rails (6) so that the tensioning trolley frame (5) can only move front and back along the longitudinal side rails (6). The parts, close to the front and rear ends, of the top surface of each groove (7) are provided with openings. Rolling wheels (8) are arranged at the openings. The rolling wheels (8) make contact with the top surfaces of the longitudinal side rails (6) through the openings so that the tensioningtrolley frame (5) can move on the longitudinal side rails (6) through the rolling wheels (8). The belt storage device has the advantages of being reasonable in structure, light in weight, easy to carry and maintain and not prone to derailing. During operation and maintenance, the labor intensity can be reduced, and the working efficiency can be improved.

Description

technical field [0001] The invention relates to coal mine underground excavation and conveying equipment, in particular to a belt storage device of a coal mine underground belt conveyor. Background technique [0002] The belt storage device is one of the important parts of the belt conveyor, and its main functions are: [0003] 1. The tension of the conveyor belt can be adjusted at any time as needed. [0004] 2. A certain length of conveyor belt can be stored for maintenance and production use. [0005] 3. Reduce the cutting damage (waste) of the conveyor belt when maintenance workers maintain the conveyor belt. [0006] 4. It is convenient for the daily maintenance of the belt conveyor. [0007] At present, the belt storage device of the belt conveyor in the coal mine is a trolley-type mobile belt storage device, which has the disadvantages of large volume, easy derailment, cumbersome repair and maintenance, so that the functions and advantages of the belt storage devic...

AI Technical Summary

Problems solved by technology

[0007] At present, the belt storage device of the belt conveyor in the coal mine is a trolley-type mobile belt storage device, which has the disadvantages of large volume, easy derailment, cumbersome repair and maintenance, so that the functions and advantages of the belt storage device cannot be brought into play.

During excavation, coal mining extension, shortening of the tail or maintenance, the labor intensity and number of workers of the miners will be increased, and it will also cause huge waste of materials and bring economic losses to the enterprise.
