Problems solved by technology
[0003] China Publicly Authorized Invention: CN207649884U discloses a clamping and vertical lifting device for hydraulic breaker testing, which can realize the performance test of the fixed vertical hydraulic breaker system, and provides an experimental platform for the performance test of the hydraulic breaker system, which can be used for different tests. However, there are still some problems in the construction of the hydraulic breaking system experiment; due to the large breaking hammer, when the operator takes the breaking hammer and places it in the process of clamping and vertical lifting device for the hydraulic breaking hammer test, it is necessary to use the lifting device During the placement process, the operator places the breaker on the lifting device. When the operator places the breaker on the lifter, the operator is in great danger. Therefore, a hydraulic breaking hammer is proposed. Hammer Vertical Test Fixture

The invention discloses a vertical test fixture for a hydraulic breaking hammer. The vertical test fixture comprises a bottom plate and two fixing plates, two cylinders are symmetrically installed on the upper surface of the bottom plate, piston rods of the cylinders are fixedly connected to the rear surfaces of the fixing plates, the bottom of one fixing plate is hinged to the top of the bottom plate, and two first sliding grooves are symmetrically formed in the inner side wall of the fixing plate. When the vertical test fixture is in use, the cylinders are started, the piston rods of the cylinders drive one fixing plate to move towards the bottom plate, after the fixing plate reaches the designated position, the breaking hammer is placed in a supporting plate, a second block is moved to clamp the breaking hammer, then the other fixing plate clamps the breaking hammer, and a first block is inserted into the second block body, so that the breaking hammer is clamped, an operator does not need to use a lifting device to fix the breaking hammer in the test fixture, and the danger degree of placing the breaking hammer in the test fixture by the operator is reduced.
Description
technical field [0001] The invention relates to the technical field of test fixtures for hydraulic breakers, in particular to a vertical test fixture for hydraulic breakers. Background technique [0002] The power source of the breaker is the pressure oil provided by the pump station of the excavator or loader, which can more effectively clean up the floating stones and the soil in the rock gaps during the excavation of the building foundation. The principle of choosing a hydraulic breaker is to choose the most suitable hydraulic breaker according to the model of the excavator and the working environment. [0003] China Publicly Authorized Invention: CN207649884U discloses a clamping and vertical lifting device for hydraulic breaker testing, which can realize the performance test of the fixed vertical hydraulic breaker system, and provides an experimental platform for the performance test of the hydraulic breaker system, which can be used for different tests. However, there...
