Embodiments of the present invention disclose a specific pressure test device, and a specific pressure and external load test method, and relate to the technical field of hydraulic support tests, in order to reduce costs of a specific pressure test and an external load test while simplifying processes of the specific pressure test and the external load test. The specific pressure test device is arranged at the bottom of a support frame of a hydraulic support test bench, and comprises: a load bearing frame for carrying the hydraulic support; a plurality of loading cylinders arranged on the loadbearing frame, wherein, when testing the hydraulic support, the plurality of loading cylinders extend out of the load bearing frame to support the hydraulic support; and a plurality of pressure sensors respectively connected with the plurality of loading cylinders, wherein, when testing the hydraulic support, the plurality of pressure sensors respectively collect the pressures received by the plurality of loading cylinders. The specific pressure test device provided by the embodiments of the present invention is used for performing a specific pressure test and an external load test on the hydraulic support.
Description
technical field [0001] The invention relates to the technical field of hydraulic support testing, in particular to a specific pressure test equipment, a hydraulic support test bench, and a specific pressure and external loading test method. Background technique [0002] Before a new hydraulic support is put into use, a specific pressure test and an external loading test are required to ensure that the hydraulic support has good safety and reliability when used in mines. Through the specific pressure test, the pressure of the base of the hydraulic support to the bottom plate can be determined, so as to avoid the situation that when the hydraulic support is used in the mine, the specific pressure will cause the base to sink into the bottom plate and make it difficult to move the support. Through the external loading test of the hydraulic support, the support performance data of the hydraulic support can be obtained, and the reliability of its structure and parts can be verifie...
