Abstract

The invention discloses a buffer damping anchor stock. The buffer damping anchor stock comprises a capstan used for winding steel slings, a lower stock body capable of being inserted into and fixed to side slope soil, an upper stock body which is in rotation fit with the capstan and a magneto rheological fluid assembly used for applying rotation damping force to the capstan. The magneto rheological fluid assembly comprises a magneto rheological fluid cavity formed inside the upper stock body and a damping rod which penetrates through the magneto rheological fluid cavity in the axial direction and is in rotation fit with the upper stock body. A blade is fixed to the rod section, located in the magneto rheological fluid cavity, of the damping rod and the damping rod is in transmission fit with the capstan. An electromagnetic coil is wound outside the magneto rheological fluid cavity. The anchor stock can be connected with a support net after the steel slings are wound on the anchor stock, and adaptability adjustment of the damping force of the support net on fallen rocks can be conducted by the anchor stock according to impact force of the fallen rocks, so that the phenomenon that the support net is fractured due to excessive loads is avoided and meanwhile the strength of the support net is utilized to the greatest extent.

Description

technical field [0001] The invention relates to a support structure, in particular to a buffer damping anchor rod. Background technique [0002] With the rise and advancement of many large-scale construction projects, man-made slopes are becoming more and more common across the country, and the treatment of rockfall on slopes has become increasingly prominent and urgent. There are currently two main methods for slope rockfall control. One is the active slope protection system, which covers and wraps various types of flexible nets, mainly steel wire rope nets, on the surface of the slope to be protected to limit the rock mass on the slope. Weathering, spalling and collapse, or controlling the movement of falling rocks within a small range. When this method is implemented, the flexible net needs to cover the entire slope, and the amount of consumables is large. At the same time, falling rocks are easy to accumulate and inconvenient to clean. Over time, it will bring a large l...
