An anti-mining deformation adjustment device for shallow-buried gas pipelines for coal mining

Abstract

The invention discloses a shallow-buried gas transmission pipeline anti-mining dynamic deformation regulating device used for coal mining. The shallow-buried gas transmission pipeline anti-mining dynamic deformation regulating device comprises a base, a supporting plate, a rotary shaft and a connecting rod, wherein two slide paths are symmetrically mounted on the upper surface of the base; two slide slots are symmetrically formed in the two sides of each slide path; movable blocks are movably mounted in the slide slots; opposite sides of the two movable blocks are connected with the two ends of the rotary shaft; a sleeve column is fixedly arranged on the upper surface of the base; an inner column is spliced in the sleeve column; the upper surface of the sleeve column is connected with thelower surface of the supporting plate through a spring; a fixed block is fixedly arranged on the lower surface of the supporting plate; a rotary slot is formed in the fixed block; the rotary shaft ismounted in the rotary slot; and the two ends of the connecting rod are separately connected with the fixed block and the rotary shaft on the movable blocks. The shallow-buried gas transmission pipeline anti-mining dynamic deformation regulating device has the advantages of regulating supporting height of integral equipment according to earth surface sinking degree, keeping a pipeline in the horizontal state, and preventing the pipeline from sinking and cracking.

Description

technical field [0001] The invention relates to the technical field of coal mining, in particular to an anti-mining deformation adjustment device for a shallow-buried gas transmission pipeline used in coal mining. Background technique [0002] The mining of underground resources will lead to different degrees of surface subsidence. Especially for coal mining under pipelines, the most common method is to leave protective coal pillars underground and reroute surface pipelines. Leaving protective coal pillars is similar to coal mining under railways. It can protect the pipeline very well, but at the cost of wasting a lot of coal resources; pipeline rerouting requires re-burying the pipeline, which greatly increases the cost of the pipeline. At present, there are not many studies and applications of protective measures for pipelines. The installation of fixed pipeline devices at pipelines cannot cope with ground subsidence. Pipelines will move downward with surface subsidence, a...
