Abstract

The invention discloses an anchor rod performance test device. The anchor rod performance test device is suitable for test analysis of dynamic shock resistance and static force tensile deformation characteristic of a common anchor rod, and comprises an anchor rod clamping device, an anchor rod positioning device, a lifting stranded wire, an impact heavy disc, a positioning guide rail, a frame body, a fixing foot frame, a positioning rod, a buffering mat and a static force hydraulic tensile device, wherein reading scales are arranged on the positioning guide rail, and a displacement sensor is arranged on the static force hydraulic tensile device. The anchor rod performance test device can be used for testing the capacities of dynamic impact, such as rock explosion resistance and rock burst, of the anchor rod, and for testing the tensile deformation characteristics of resisting against surrounding rock deformation of the anchor rod, can be used in both a dynamic state and static state, is simple and convenient to operate, and is strong in applicability.

Description

technical field [0001] The invention relates to a bolt performance testing device, more specifically a testing device for static tensile deformation and dynamic impact resistance performance of a bolt, belonging to the bolt performance testing technology. Background technique [0002] Bolt support is a common method of surrounding rock reinforcement and support in ground engineering such as slopes and deep foundation pits, as well as underground caverns such as tunnels and stopes. The performance of anchor bolts usually refers to the static tensile deformation characteristics and dynamic impact resistance characteristics of anchor bolts. In recent years, with the emergence of large deformation of surrounding rock, rockburst, rock burst and other highly destructive disasters, the tensile deformation characteristics and dynamic anti-shock characteristics of anchor rods against deformation are the key to the effect of anchorage support. At present, the material testing machine...
