Steel pipe scaffold fastener mechanical property testing machine

Abstract

The invention belongs to the technical field of mechanical property testing machines and relates to a steel pipe scaffold fastener mechanical property testing machine. The steel pipe scaffold fastenermechanical property testing machine comprises a testing machine body and a protective structure arranged on the testing machine body; the protective structure comprises a supporting column and a protective plate connected to the supporting column; a protective cavity is formed in one side, facing the test machine body, of the protective plate; a baffle which can approach or move away from the testing machine body is installed between the side walls of the protective cavity; and a buffer bag is arranged between the baffle and the bottom of the protecting cavity. Since the buffer bag is adopted, when small fragmented blocks fly out and impact on the baffle, the baffle pushes and squeezes the buffer bag, so that the buffer bag deforms, and therefore, kinetic energy is converted into elasticpotential energy, a buffering effect is achieved, impact on the protective structure is reduced, and the service life of the protective structure is prolonged; and the kinetic energy of the flying outof the small fragmented blocks is reduced, so that the safety of operators is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical performance testing machines, in particular to a mechanical performance testing machine for steel pipe scaffold fasteners. Background technique [0002] The steel pipe scaffold fastener mechanical performance testing machine is a testing equipment designed according to the requirements of the mechanical performance test method in the national standard GB15831-2006 "Steel pipe scaffold fastener". The testing equipment can test the mechanical properties of right-angle fasteners, rotary fasteners, butt fasteners and bases in anti-slip, anti-destructive, torsional rigidity, tensile and compressive. In the design, a force measuring system composed of high-precision tension and pressure sensors and high-performance force measuring instruments is adopted, which has the function of tension and pressure bidirectional measurement, and has the advantages of high measurement accuracy and fast speed.

AI Technical Summary

Problems solved by technology

The protective net has mesh holes, and the fasteners of the steel pipe scaffolding may be broken after being squeezed, so the broken pieces that fly out may fly out of the mesh holes of the protective net and cause harm to people, so the above patent The protection structure in the medium has poor protection effect on the operator
