Hydraulic support testing device

Abstract

The invention relates to the technical field of hydraulic support testing and discloses a hydraulic support testing device for simulating operating conditions of an inclined coal seam and detecting tilting and slipping prevention performances, stability and reliability of a hydraulic support in the inclined coal seam. The hydraulic support testing device comprises carrier roller devices, roller discs and a body frame, the carrier roller devices are fixedly arranged on a foundation, the roller discs are rotationally mounted on the carrier roller devices, and the body frame is arranged on lateral sides of the roller discs. The body frame comprises a base, a top beam and vertical columns, wherein the base is fixedly connected with the roller discs, the top beam is fixedly connected with the roller discs, and the vertical columns are connected between the base and the top beam. The hydraulic support testing device further comprises a moving platform, guide rails and a loading platform, wherein the moving platform is in slide connection with the vertical columns, the guide rails are arranged on the moving platform and perpendicular to the vertical columns, the loading platform is in slide connection with the guide rails, and a testing space for hydraulic supporting testing is formed between the loading platform and the base. By the technical scheme, a tested hydraulic support can berotated to a tilting angle corresponding to the inclined coal seam, and complex loading of the hydraulic support is realized.

Description

technical field [0001] The invention relates to the technical field of hydraulic support tests, in particular to a hydraulic support test device. Background technique [0002] In the field of coal mining, compared with ordinary coal seams, inclined coal seams put forward higher requirements for mining technology. For example, in the support of coal mining face, it is necessary to use large-inclination hydraulic support as support equipment. This type of support has the anti-fall and anti-skid performance that ordinary supports do not have, and can well adapt to the requirements of inclined coal seam mining. Therefore, the use of large-inclination hydraulic supports is increasing year by year. [0003] The hydraulic support test device is a special equipment for the detection and inspection of the hydraulic support, and it is necessary to carry out a loading test on the hydraulic support by simulating the actual working conditions of the coal mine. However, the existing hyd...

Problems solved by technology

However, the existing hydraulic support test device is mainly a frame structure, which does not have a rotatable function, let alone perform a composite loading test on a large-inclination hydraulic support at a certain inclination angle, so it is impossible to simulate the working conditions of an inclined coal seam, which leads to difficulties. It is difficult to test the reliability and stability of the hydraulic support with a large inclination angle by performing an anti-fall and anti-skid performance test analysis on the hydraulic support with a large inclination angle
