Description

Technical Field

[0001] The utility model relates to the technical field of quick connectors, in particular to a quick connector for a coal mine filling pipe. Background Art

[0002] Modern coal mines advocate green mining technology. After coal mining, the roof does not collapse, the surface ecology is not damaged, and the recovery rate is improved. The coal industry has proposed a new coal mining process and technology of "three down and one up". The paste filling mining technology is adopted. Abandoned coal gangue or construction foundation pit sand, fly ash, and an appropriate amount of cement are prepared from the surface into a paste and injected into the underground goaf with a concrete pump. After solidification, low-strength concrete is formed, which becomes an artificial support body in the coal mine and all the coal is mined. This process requires the use of a large number of filling pipes. The filling pipes need to be disassembled and cleaned regularly or because the paste is blocked in the pipes. If the filling paste is blocked or other accidents occur during the filling process, the pipes need to be disassembled in time to clean the paste in the pipes. If the paste cannot be cleaned in time, the paste solidifies in the pipes, which will cause the pipes to be scrapped, affecting coal mine production and causing waste. Generally, the length of a filling pipe ranges from several thousand meters to ten thousand meters, so the filling pipes are required to be connected and disassembled conveniently and quickly. Therefore, there is an urgent need for a quick-connect pipe joint that is quick and easy to install, safe and reliable. When processing and manufacturing the filling pipe, due to the long filling pipe, large-scale equipment is required to process the pipe joint, the processing efficiency is low, and the cost is high. If the filling pipe manufacturing is divided into filling pipe fittings and pipe joints, and they are manufactured separately and then welded, the manufacturing process can be simplified, the manufacturing cost can be greatly reduced, the manufacturing is convenient, and the use cost is reduced. Therefore, there is an urgent need for a quick connector for coal mine filling pipes to solve the above technical problems. Utility Model Content
