Problems solved by technology

This type of advanced support method and support bracket has low support strength and slow speed, and the biggest defect is that it cannot support the side walls, which is likely to cause secondary loosening of the surrounding rock, resulting in side walls and destroying the overall rock formation of the roadway. safety and stability, repeated maintenance is required, so that the relevant maintenance work has become the most labor-intensive work in the fully mechanized mining and fully mechanized caving face, and this type of work has a high risk factor, and accidents occur frequently in actual operation
[0004] In response to this situation, the industry urgently needs a support device that can provide the necessary side protection function, especially in the advance support area, to solve the problem of using single hydraulic props, double-row wooden props, etc. in the existing advance support technology. The structure is unable to support the side panels leading to problems with the side panels

Abstract

The invention discloses a lateral wall supporting device and a supporting bracket with the same. The lateral wall supporting device is arranged outside a supporting bracket body so as to provide a lateral wall supporting function. The lateral wall supporting device comprises a power supporting part and a supporting wall board part, wherein the power supporting part is used for supporting the supporting wall board part and providing the power for the supporting wall board part to move, the bottom end of the power supporting part is movably connected to a base of the supporting bracket body, and the top end of the power supporting part is movably connected to the bottom end of the supporting wall board part; and the supporting wall board part is used for supporting the lateral wall, and the top end of the supporting wall board part is movably connected to the top beam of the supporting bracket body. According to the lateral wall supporting device and the supporting bracket with the same, the lateral wall supporting function can be provided and the problem of the wall caving of the lateral wall can be effectively avoided.

Description

technical field [0001] The invention relates to a support device, in particular to a side support device and a support bracket provided with it. Background technique [0002] At present, the support methods for the leading area of ​​the two parallel grooves in the fully mechanized mining face in my country mainly use U-shaped steel, I-steel metal brackets, anchor rods, anchor nets and other combined support methods. As the fully mechanized mining face continues to advance, the leading pressure also increases Moving forward, the roadways at both ends of the working face will also be damaged, and the problem of side panels is likely to occur. Therefore, the "Coal Mine Safety Regulations" has regulations on this aspect: within 20m of the connection between all safety exits and roadways in the coal mining face Inside, the support must be strengthened. [0003] However, the actual situation is that the advanced support devices widely used in coal mines are still generally supporte...
