A test platform for comprehensive mechanical properties of anchor components and anchor rods

Abstract

The invention discloses an anchoring assembly and a comprehensive mechanical property test platform for an anchoring rod of the anchoring assembly. The anchoring assembly comprises a first anchoring half drum and a second anchoring half drum, wherein one end of the first anchoring half drum is provided with a first half flange and an end part sealing plate, and the other end of the first anchoringhalf drum is provided with a second half flange; one end of the second anchoring half drum is provided with a first matching half flange and a matching end part sealing plate, and the other end of the second anchoring half drum is provided with a second matching half flange; the edge of the first anchoring half drum is provided with a fixed convex edge; the edge of the second anchoring half drumis provided with a matching fixed convex edge; the fixed convex edge and the matching fixed convex edge are arranged into a mounting groove; a fixing bolt is in threaded spinning fit with an anchoringsliding bar on the other side after passing through an anchoring sliding bar on one side, the fixed convex edge and the matching fixed convex edge, so as to integrally assemble the anchoring slidingbars, the fixed flange and the matching fixed flange; the second half flange and the second matching half flange are respectively assembled and fixed with the end part sealing plates through bolts; the end part sealing plates close the other end of an anchoring cavity.

Description

technical field [0001] The invention relates to a test device, in particular to an anchor assembly and an anchor rod comprehensive mechanical performance test platform. 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 test can...

Problems solved by technology

These are not considered in the above-mentioned patents. In actual use, the roadway designer often infers the selection requirements and construction methods of the bolt through the analysis of the rock and soil of the roadway and the mechanical analysis of the bolt. However, this is an ideal situation. In the actual construction and use process, the mechanical changes of the anchor are very complicated. Therefore, the applicant believes that the test of the mechanical properties of the anchor should not simply test the various forces on the anchor directly, but simulate During the construction of the anchor bolt, the change of the rock and soil after construction, and the comprehensive stress applied to the anchor bolt at the same time are tested
