Description

Inclined coal seam roadway support equipment Technical Field The invention relates to the technical field of underground coal mine support, in particular to inclined coal seam roadway support equipment. Background The inclined roadway is a coal science and technology noun, refers to a roadway with obvious gradient, is one of mine roadways, and is opposite to a horizontal roadway. The coal mine in China is mainly underground mining, a large number of roadways need to be dug underground, roadway supports are adopted to keep the roadways smooth and surrounding rocks stable, and the method has important significance for coal mine construction and production. The basic purpose of supporting the roadway is to alleviate and reduce the movement of surrounding rocks, so that the section of the roadway is not excessively reduced, and scattered and destroyed surrounding rocks are prevented from falling down. Hydraulic supports are one of the most prominent supporting devices of the current mechanized coal face. However, when the hydraulic support is applied to inclined coal seam roadways (such as ascending and descending), the working environment of the hydraulic support is obviously different from that of a horizontal roadway due to the inclination angle of the roadway bottom plate. The two outstanding technical problems are that firstly, the bracket is required to bear the top plate pressure in the vertical direction, the self weight and the top plate load of the bracket can generate obvious sliding horizontal bisection force along the inclined direction, so that the base is easy to slide downwards along the roadway bottom plate, the bracket loses stable supporting posture, and even a reverse bracket accident is caused in severe cases. Second, the support height and the support force of the existing hydraulic support are realized completely by relying on the hydraulic system to drive the hydraulic cylinder. Once the hydraulic system has faults such as leakage, pipeline burst or pump station decompression, the hydraulic cylinder cannot maintain pressure, the top beam immediately loses supporting force and sinks, and continuous passive support cannot be provided for the top plate. In inclined roadways, this problem is particularly dangerous because the unsupported roof is very susceptible to large area collapse (i.e. "pull-out") along the inclined plane, severely threatening the life safety of the operators and equipment. In order to solve the problems, the prior art mainly adopts measures such as adding an anti-skid shoe on a base or adding a single hydraulic prop on the lower end of a working surface for auxiliary reinforcement. However, these approaches either add complexity to the apparatus itself, require additional hydraulic control circuitry, or require manual extensive auxiliary operations, are labor intensive, inefficient, and fail to provide automatic, efficient passive mechanical support in the event of failure of the hydraulic system main circuit. Therefore, how to design an inclined coal seam roadway support device which can not only effectively resist sliding in an inclined direction, but also provide reliable standby support when a hydraulic system fails is a technical problem to be solved urgently by those skilled in the art. Disclosure of Invention The invention aims to provide inclined coal seam roadway support equipment for achieving the purpose of improving the stability of a hydraulic support. In order to achieve the above purpose, the inclined coal seam roadway support equipment comprises a base, wherein the top end of the base is rotationally connected with a connecting rod, the top end of the connecting rod is rotationally connected with a shield beam, the top end of the shield beam is rotationally connected with a top beam, one end of the top beam is provided with a front beam, the top end of the base is positioned at one end of the connecting rod and is provided with four hydraulic cylinders, the hydraulic cylinders are used for adjusting the height and the angle of the top beam, the position of the base is positioned through a positioning mechanism, the top beam is subjected to reinforcement and support operation through a supporting mechanism, the positioning mechanism comprises sliding grooves which are symmetrically arranged on two sides of the top beam, two sides of the base are symmetrically and fixedly connected with mounting plates, the outer walls of the mounting plates are symmetrically provided with mounting grooves, one side of the mounting plates is provided with a through hole, the inner wall of each mounting groove is slidably connected with a mounting seat, the two mounting seats are fixedly connected with a supporting seat, the top end of each mounting seat is provided with a connecting groove, the inner wall of each connecting groove is slidably connected with a connecting rod, and the sliding rod is fixedly connected with the sliding rod.
