Problems solved by technology

[0003] At present, there are many outstanding problems in the manual movement of advanced support equipment, such as large number of people, low efficiency, difficult movement, high labor intensity of workers, and frequent safety accidents during the movement process, which seriously affects the increase of coal production.
[0004] The step-type hydraulic support can be divided into an integral type advance support hydraulic support and a split type advance support group. The main problem of the step-type movement method is that the roof must be repeatedly supported for the needs of the advance support movement, which is easy to cause the roof to break. It is not conducive to the safe management and maintenance of the roof
The self-moving mechanism used by the stepping hydraulic support will cause serious damage to the floor of the roadway;
[0005] The crawler walking type advance support is a method of moving the frame with pressure. The sliding friction generated by such a moving method will seriously affect the service life of the support, and will bring defects such as large forward resistance and extremely unstable walking. , it is easy to cause harm to the safety of roadway personnel
At the same time, when the bottom plate is soft or uphill, it is difficult to move the crawler hydraulic support
[0006] The following problems exist in the advanced support bracket group transported by trackless rubber-tyred vehicles. When the floor of the roadway has a bottom drum or is weak and muddy, it is difficult for the vehicle to pass under the condition of no load.
Diesel engine is used as power, and the exhaust gas along the tank is easy to exceed the standard and alarm
At the same time, the vehicle transportation system takes up a lot of space and is relatively poor in safety.
[0007] When using the monorail crane to transport the advanced support equipment, the monorail crane takes the anchor rod (cable) above the roadway as the suspension point. As the working face moves forward, the monorail crane also needs to be moved forward and installed repeatedly, increasing the advanced support workload
Moreover, the suspension point of the monorail crane is easily affected by the quality of the installation and is not firm enough to cause injury accidents. When moving the advanced support equipment, the monorail crane is easy to swing freely in the middle of the roadway, which poses a great safety hazard.

Abstract

The invention relates to the technical field of coal industry, and particularly relates to a migration system and a migration method for an advanced reinforced support bracket of a stope face. According to the migration system and the migration method, the advanced reinforced support bracket to be withdrawn is transported to a designated position through a closed-loop type conveying mechanism, so that the whole process of mechanized operation of support withdrawal and migration of an advanced support is realized, the labor intensity of the advanced support is greatly reduced, meanwhile, the potential safety hazards of the support withdrawal, migration and support of the advanced support are eliminated, and the problems that a roadway floor is uneven, the space is narrow, and the support withdrawal and migration of the advanced reinforced support are difficult are solved. The migration system and the migration method are mainly applied to the advanced support of the stope face and have great application prospects in coal mines.

Description

technical field [0001] The invention relates to the technical field of the coal industry, in particular to a moving system and a moving method for an advanced reinforced support bracket of a mining face. Background technique [0002] In order to prevent the deformation, movement and destruction of the surrounding rock of the roadway caused by the superposition of the advanced bearing pressure and the bearing pressure along the inclined direction of the coal mining face, and ensure the smooth flow of the upper and lower exits of the working face, the two lanes of the coal mining face need to adopt advanced strengthening support . The most distinctive feature of the advance support is that the advance support equipment needs to move forward continuously with the advancement of the coal mining face. According to the transportation methods of domestic advance support equipment, advance support can be divided into five categories: manual movement, step-by-step movement, crawler ...
