Problems solved by technology

[0004] In order to make up for the above deficiencies, this application provides an anchoring device for rock formation monitoring points, which aims to improve the current monitoring work of rock formations in coal mines. In the traditional anchoring method of components, there is an anchor point displacement caused by construction and lithological changes. The measurement accuracy is reduced due to slippage and even causes the anchoring effect to fail

Abstract

The invention provides a rock stratum migration monitoring point anchoring device, and belongs to the technical field of rock stratum migration monitoring. A rock stratum migration monitoring point anchoring device comprises a bottom plate, a rotating plate is rotationally installed on the bottom plate through a bearing, a support is installed on the rotating plate, a winding assembly is rotationally installed on the support through a bearing, and a reciprocating mechanism is installed on one side of the support. The winding assembly is in transmission connection with the reciprocating mechanism through an arranged belt, a first guide wheel is installed on the reciprocating mechanism, and two symmetrical first hinge seats are fixedly installed on the support, so that a large amount of anchor piece cost is saved, and the problems of slippage, failure and the like between an anchor piece and a surrounding rock-soil body caused by a traditional anchoring method can be effectively solved; the construction efficiency of the anchor is improved, the reliability and applicability of the anchor are improved, the risk caused by failure of the anchor in engineering is reduced, and compared with a chemical anchoring method, the method has no pollution to the geological environment and the underground water environment.

Description

technical field [0001] The present application relates to the technical field of rock formation migration monitoring, in particular, to an anchoring device for a rock formation migration monitoring point. Background technique [0002] At present, the line traction anchor fixed point device is used in the research of coal mine surface subsidence and rock formation migration. The traditional mechanical component is to put the anchor claw into the surface drill hole, and use methods such as pressurization or grouting to improve the anchor claw component and the surrounding rock of the hole wall. The friction force between them can achieve the purpose of synchronous migration of the measuring point and the rock formation. [0003] The defects of the traditional technical solution are as follows: In the current coal mine stratum movement monitoring work, the traditional anchoring method of the component has the misalignment and slippage of the anchorage point caused by constructi...
