Supercharger mechanism and anchor rod comprehensive mechanical performance test platform thereof

Abstract

The invention discloses a supercharging mechanism and an anchor rod comprehensive mechanical performance test platform thereof. The supercharging mechanism comprises a fulcrum assembly, wherein the fulcrum assembly is mounted at the end, far away from a first pressure connecting rod and a second pressure connecting rod, of a pressure applying plate; the fulcrum assembly comprises a fulcrum supportplate which is fixed on the pressure applying plate; a step-down sliding slot is formed in the fulcrum support plate; the step-down sliding slot is glidingly assembled with a limit sliding rod; one end of the limit sliding rod is fixedly connected with a telescopic support plate; the limit sliding rod passes through one end of a stop plate to be fixedly connected with one end of a first fulcrum spring; the other end of the first fulcrum spring is fixedly connected with the pressure applying plate; the telescopic support plate is assembled and fixed with each of the first fulcrum support plateand the second fulcrum support plate; a fulcrum switching electromagnet is mounted between the first fulcrum support plate and the second fulcrum support plate; and the fulcrum switching electromagnet is assembled with one end of a fulcrum switching telescopic shaft; and the other end of the fulcrum switching telescopic shaft passes through the second fulcrum support plate to be assembled and fixed with a fulcrum block.

Description

technical field

[0001] The invention relates to a test device, in particular to a pressurization mechanism and a test platform for comprehensive mechanical properties of a bolt. Background technique

[0002] In the Chinese invention patent whose publication number is CN104075943B, a kind of test bench and test method for testing the comprehensive mechanical properties of anchor rods are disclosed. The test mechanism and the bending load test mechanism, axial load test mechanism, shear load test mechanism and impact load test mechanism set on the working test bench; through this test bench, the bolt installation and working process can be simulated in the laboratory, and Apply single or multiple combined external forces such as torsion, tension, bending, shearing and impact to the anchor; use independent loading systems to apply corresponding loads to the anchor, and can perform various loads in the installation and working process of the anchor respectively. The independent...
