Embodiment Construction

[0032] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0033] The specific embodiment 1 of hydraulic support test bench of the present invention, as Figure 1 to Figure 6 As shown, the hydraulic support test bench includes a base, a column, and a loading box assembly for the side guard plate test that can be lifted and fixed on the column. The loading box assembly includes a loading box and a lateral loading part. The loading box includes a box body 8 , the box body 8 is provided with a telescopic oil cylinder that can be retracted in the horizontal plane, and the telescopic oil cylinder retracts into the side of the box body 8 and drives the loading box to climb and descend along the column through the climbing oil cylinder, and the loading box is fixed on the corresponding column of the column through a pin In the hole. In the box body 8, there are two rows of top pressure hydraulic cylinders that are eve...

Abstract

The invention provides a loading box assembly for side guard plate testing and a hydraulic support test-bed, and relates to the technical field of coal mining equipment detection. The hydraulic support test-bed comprises a loading box, wherein the loading box comprises a box body and a floating block; supporting plates are arranged on two opposite sides of the floating block; a plane on which thesupporting plates are located is opposite to side guard plates of a hydraulic support to be tested; accommodating grooves are formed in the supporting plates; two clamping plates are assembled in theaccommodating grooves under guidance; driving parts comprise vertical and lateral hydraulic cylinders; the lateral hydraulic cylinder is inserted into the two clamping plates; a push rod extends outwards to load the side guard plate. The vertical hydraulic cylinder is fixed to the lower end part of a vertical channel in a vertical panel, and can drive the two clamping plates to move up and down, thus adjusting the loading position of the lateral driving part. When in use, the hydraulic support is placed at a corresponding position, the lateral hydraulic cylinder is controlled to extend outwards, and opposite extrusion force is formed on the two side guard plates of the hydraulic support, which is closer to the actual working condition, thereby solving the existing problem of limited function and improving the reliability of the hydraulic support.

Description

technical field [0001] The invention relates to the technical field of coal mining equipment detection, in particular to a loading box assembly and a hydraulic support test bench for side guard plate tests. Background technique [0002] With the development of coal mine technology, the hydraulic support is used as the support equipment of the coal mining face. Two hydraulic supports are arranged side by side. [0003] Usually, side guards are installed on both sides of the top beam and the cover beam of the hydraulic support, which are used to move the movable side guards outward to seal the gap between the frames when the side push jack of the hydraulic support is extended, so as to prevent gangsters and guide , anti-fall and frame adjustment functions. Correspondingly, when the side push jack is retracted, the movable side guard is retracted, and the resistance when moving the frame can be reduced, in order to improve the adaptability of the hydraulic support in use. Th...
