The invention discloses a pressure test board and a method for lifting an operating platform thereof, in order to achieve the purpose of lowering the cost and increasing the safety. The pressure test board comprises four upright columns, an upper operating platform, a lower operating platform arranged under the upper operating platform, a lifting jack, and a fluid control device, wherein positioning holes are uniformly arranged on each upright column along the length direction of the upright column; the upper and lower operating platforms are arranged among the four upright columns; four lifting fixing jacks are respectively arranged on the upper and lower operating platforms corresponding to the four upright columns; each lifting fixing jack comprises a cylinder tube fixed on the corresponding operating platform and a telescopic pin shaft arranged in the cylinder tube; the pin shafts are arranged in the corresponding positioning holes on the corresponding upright columns; the lifting jack is arranged between the upper and lower operating platforms; and the fluid control device is used for controlling the fluid supplied to the lifting fixing jacks and the lifting jack. The pressure test board provided by the embodiment of the invention can be applied to testing the pressure of a hydraulic bracket.
Description
technical field [0001] The invention relates to the technical field of pressure testing of hydraulic supports, in particular to a pressure testing platform and a method for lifting a working platform thereof. Background technique [0002] In the prior art, the pressure test bench of the common hydraulic support includes four columns, the four columns form a rectangular frame, positioning slots or holes are evenly arranged on each column along the length direction of the column, and the workbench is horizontal It is arranged between the four uprights and fixed on the four uprights through pin shafts. [0003] When it is necessary to perform a pressure test on the hydraulic support, the workbench is hoisted by the crane first, and at the same time, the pin shaft fixing the workbench is manually pulled out. The shaft is plugged in to position the workbench; then, the hydraulic support is moved below the workbench, the hydraulic support is raised and pressed against the lower s...
