Problems solved by technology

[0003] However, since the load of the hydraulic jack and the hydraulic jack often change within a certain angle during actual work, when the performance of the hydraulic jack is tested, the test hydraulic jack and the loading hydraulic jack are arranged at 180°, which often cannot simulate the test hydraulic jack. Due to real working conditions, it is difficult to accurately detect the performance indicators of hydraulic jacks

Abstract

The invention provides an angle-adjustable hydraulic jack opposite jacking test device, which comprises a bottom plate and a base composed of at least two base main rib plates, a U-shaped pore plate perpendicular to the bottom plate is fixedly arranged at one ends of every two base main rib plates, and a jack fixing seat is fixedly arranged at the other ends of every two base main rib plates. A sliding block capable of sliding back and forth between the two base main rib plates is arranged in the middle of every two base main rib plates, a sliding base capable of moving up and down on the sidewall of the U-shaped pore plate is arranged on the side wall of the U-shaped pore plate between the two base main rib plates, the cylinder bottom end of a test jack is hinged to the sliding base, andthe piston rod end of the test jack is connected with one side of the sliding block. The piston rod end of the loading jack is connected with the other side of the sliding block, and the cylinder bottom end of the loading jack is connected with the jack fixing base. The angle-adjustable hydraulic jack opposite jacking test device provided by the invention can accurately detect the performance indexes of the hydraulic jack when a certain angle change possibly exists between the load and the hydraulic jack in the actual working condition.

Description

technical field [0001] The invention relates to the technical field of hydraulic jack performance detection, in particular to an angle-adjustable hydraulic jack jacking test device. Background technique [0002] At present, the device for testing the performance index of the hydraulic jack is to arrange the test hydraulic jack and the loading hydraulic jack at an angle of 180°, and the loading jack provides the test jack with working resistance under the target working condition. By counting the number of reciprocating movements of the test jack to evaluate whether the performance of the test jack meets the requirements. [0003] However, since the load of the hydraulic jack and the hydraulic jack often change within a certain angle during actual work, when the performance of the hydraulic jack is tested, the test hydraulic jack and the loading hydraulic jack are arranged at 180°, which often cannot simulate the test hydraulic jack. Due to the real working conditions, it is...
