Abstract

The present invention discloses a hydraulic support pushing frame composite external loading test device. The hydraulic support pushing frame composite external loading test device comprises a rectangular frame body, and a pull rack base is arranged at one end of the frame body slidably along a transverse direction and is equipped with a hinge member. The frame body located at one side or two sides of the pull rack base is equipped with the laterally pushing jacks, and the piston rods of the laterally pushing jacks are in hinge joint with the hinge member. A sliding plate is arranged on the upper surface of the frame body slidably, push-pull jacks are in hinge joint with the two sides of the frame body respectively along a longitudinal direction, and the piston rods of the push-pull jacks are in hinge joint with the sliding plate separately. The advantages of the present invention are that: the lateral and vertical composite external loading test of the hydraulic support pushing frame is finished conveniently by using the external jacks to press, and by being compared with a conventional internal loading detection method of using a pump station to provide the pressure, the hydraulic support pushing frame composite external loading test device is few in investment and simple in structure, is convenient to use, and is convenient for the concentrated management and the standard operation.

Description

technical field [0001] The invention relates to the field of detection of coal mining equipment, in particular to a composite external loading test equipment for a hydraulic support pushing frame. Background technique [0002] The push frame is an important part of the hydraulic support, and it is the executive part for the hydraulic support to complete the work of pushing and pulling. The quality of the moving frame directly affects the service life of the hydraulic support. According to the national standard GB25974.1-2010, the lateral and vertical composite loading test needs to be carried out on the moving frame of the hydraulic support. [0003] At present, the domestic hydraulic support test bench can only meet the test requirements of the hydraulic support top beam, cover beam, base and other components, and lacks specific test equipment and methods for the hydraulic support frame. The National Coal Mine Support Equipment Quality Supervision and Inspection Center ha...
