Abstract

The invention relates to a magneto-rheological fluid support anchor rod, which includes a yielding anchor shell, a bolt body, a yielding buffer mechanism, a yielding pressure sensing mechanism, a magnetorheological damper, a supporting pad and a controller. The pressure buffering mechanism is coaxially arranged inside the yielding anchor shell, and the bottom end of the anchor body is coaxially fixedly connected with the bottom end of the working part of the yielding buffering mechanism, so that the pressure sensing mechanism senses the coaxial fixed connection with the anchor body, and the magnetorheological The working end of the damper is coaxially fixedly connected to the top of the anchor rod body, and the support plate is coaxially arranged on the top of the magnetorheological damper, so that the pressure induction mechanism and the magnetorheological damper are both electrically connected to the controller, and the structure of the device is stable. It can effectively reduce the influence of surrounding rock deformation on the bolt body, and make the installation workpiece more stable relative to the bolt body.

Description

technical field [0001] The invention relates to the field of bolt devices, in particular to a magnetorheological fluid supporting bolt. Background technique [0002] With the demand for energy for a large number of infrastructure construction and economic development, bolting technology will be used in water conservancy projects, tunnel projects and mining projects. In tunnel engineering, most tunnels in my country have complex geological conditions and difficult tunnel maintenance. The bolt technology has significantly improved the tunnel support effect, greatly reduced support costs, and reduced labor intensity. The traditional anchors include split wedge anchors, inverted wedge anchors, and expansion shell anchors, etc., but these anchors have low anchoring force, low support stiffness, and poor reliability. Although the existing yielding support bolts can bear greater force and play the role of yielding pressure, the overall stability is not high, and there are certain ...
