Abstract

The invention relates to an energy-absorbing and impact-resisting anchorage device assembly and a mounting method thereof. The energy-absorbing and impact-resisting anchorage device assembly comprises a base plate, an energy-absorbing and impact-resisting aligning pad, an energy-absorbing and impact-resisting anchor ring and a clamping piece. The steel strand is sleeved with the energy-absorbing impact-resistant anchor ring, and external threads are manufactured on the outer wall of the energy-absorbing impact-resistant anchor ring. The upper end part of the energy-absorbing and impact-resisting anchor ring is in threaded connection with the energy-absorbing and impact-resisting aligning pad, and an internal thread through hole matched with the external thread is formed in the energy-absorbing and impact-resisting aligning pad along the axial direction. The impact energy can be effectively absorbed, the impact resistance of an anchorage device assembly part under the impact load is improved, and the anchoring force of the anchor cable is kept.

Description

technical field [0001] The invention belongs to the technical field of coal mine support, and relates to an energy-absorbing and shock-resistant anchor assembly and an installation method thereof, in particular to a mine energy-absorbing and shock-resistant anchor assembly with anti-shock load and adapting to high ground pressure and large deformation and the same. installation method. Background technique [0002] The coal mining roadway needs to be supported with anchor cables. The ordinary anchor cables are composed of steel strands, anchor assemblies and pallets. During construction, first drill holes in the coal seam (or rock layer), and then feed resin into the drilled holes first. Anchoring agent, then stir the steel strand and bond it with the resin anchoring agent. The lower end of the steel strand is supported by a pallet and set on the steel strand, which is close to the coal seam. Finally, the steel strand is stretched, and the clip anchor is used to anchor the s...
