Description

Technical Field

[0001] The utility model relates to the technical field of reserved pipe plugging, in particular to a plugging structure for reserved pipes in gas control. Background Technique

[0002] Gas refers to the harmful gas mainly composed of coalbed methane in the mine, mainly methane. Sometimes it refers to methane alone. Gas is a colorless, odorless, tasteless gas that can burn or explode. It is insoluble in water and has a higher diffusivity than air. Gas is non-toxic, but when the concentration is very high, it will cause asphyxiation. When conducting daily gas pipeline control, plugging through reserved pipes is required for gas pipeline control operations.

[0003] For example, the application number 202311375048.6 discloses a plugging structure for reserved pipes in gas control, including a plugging plate assembly; the plugging plate assembly includes a fixed plate, a moving plate, a plugging piece and a sealing strip. The rear end face of the fixed plate is fixedly connected to the front end of the abutting block, and the inside of the fixed plate is a hollow structure with a rectangular plate longitudinally arranged. When plugging the inside of the reserved pipe main body, after controlling the telescopic rod of the telescopic part to move outwards and elongate, the moving plate, the first extension plate and the second extension plate are pushed to move outwards and unfold. The plugging piece and the fixed plate form a complete circular structure. After starting the hydraulic cylinder, the push rod drives the push plate to move forward. By moving the limiting rod inside the installation sleeve, the directional movement of the push plate is realized. Further, the fixed plate is pushed forward, so that the plugging piece is closely attached to the inner wall of the reserved pipe main body, and the inside of the reserved pipe main body is plugged, solving the problem that it is difficult to ensure the supportability and airtightness when relying on the bladder to plug the pipeline.

[0004] However, when this plugging structure for reserved pipes in gas control is in use, although it can perform better plugging operations on gas, the specifications of the rubber plugs are often used in a relatively fixed manner, and the use specifications of the rubber plugs cannot be adjusted according to the thickness of the reserved pipeline. Moreover, the disassembly, installation and replacement of the rubber plugs are not very convenient, thus affecting the plugging tightness of the reserved pipes.

[0005] Therefore, in view of this, research and improvement are carried out on the existing structural deficiencies, and a plugging structure for reserved pipes in gas control is proposed. Content of the Utility Model
