Automatic coal sliding hole anti-blocking device and using method

Abstract

The invention relates to an automatic coal sliding hole anti-blocking device. The automatic coal sliding hole anti-blocking device comprises a control assembly, a first sleeve, a first roller, a second sleeve, a second roller and a fixed connecting cylinder, wherein the first sleeve, the first roller, the second sleeve, the second roller and the fixed connecting cylinder are arranged from top to bottom, the bottom end of the first sleeve is rotationally connected with the top end of the first roller, the bottom end of the first roller is rotationally connected with the top end of the second sleeve, the bottom end of the second sleeve is rotationally connected with the top end of the second roller, the bottom end of the second roller is rotationally connected with the top end of the fixed connecting cylinder, the outer side walls of the first roller and the second roller are fixedly connected with transmission steel belts in a sleeved mode, stirring protruding blocks are welded to the inner side walls of the first roller and the second roller, gear teeth are welded to the outer side walls of the transmission steel belts, and a gravity sensor is fixedly mounted on the inner side wallof the fixed connecting cylinder. The anti-blocking device can achieve the effect of preventing a coal outlet from being blocked, is high in automation degree, can achieve unmanned supervision and management, has repeatability, and can greatly avoid serious safety accidents.

Description

technical field [0001] The invention belongs to the technical field of mining machinery, and in particular relates to an automatic coal mine hole anti-blocking device and a using method. Background technique [0002] The coal-sliding eye plays a key role in the coal transportation process, and is responsible for the dual tasks of coal-sliding and temporary coal storage. There are many reasons for the blockage of the coal-sliding eye, mainly due to hydrogeology, parameter setting, construction quality and daily management. Congestion can temporarily interrupt the transportation system if it is mild, and force a mining area or even the entire mine to stop production if it is severe. At present, the commonly used methods to deal with blockage are: 1. Manual dredging method. Manual dredging method can only be used for non-serious blockage. Explosives are strictly controlled, the operation period is long, and the explosion generates sparks, which may easily cause other explosion...

AI Technical Summary

Problems solved by technology

At present, the commonly used methods to deal with blockage are: 1. Manual dredging method. Manual dredging method can only be used for non-serious blockage. Explosives are strictly controlled, the operation period is long, and the explosion generates sparks, which may easily cause other explosion accidents; 3. The air cannon dredging method is complicated to operate and has poor flexibility; 4. Hydraulic fracturing, which wastes water resources seriously and causes the site construction environment to be harsh. Affect the smooth development of subsequent construction operations

[0003] In view of the above problems, although a method of dredging meteorological fracturing by using high-pressure gas blasting has been developed, it is often necessary to set up positioning drilling first and then arrange fracturing equipment during construction, so the construction is difficult and the construction efficiency is low. During drilling operations, fracturing equipment layout and recovery operations, manual operations by isomorphic staff are required, which greatly reduces work efficiency and increases the labor intensity and work costs of staff. Therefore, a method that can Anti-clogging, high degree of automation, unmanned supervision and management, and repeatability, which can greatly avoid the occurrence of serious safety accidents.
