Description

Technical Field

[0001] The utility model relates to the field of flange separation, in particular to a flange separation auxiliary device. Background Art

[0002] The main means of preventing and controlling floor limestone water hazards in coal mines is to use comprehensive grouting reinforcement on the coal seam floor of the working face. By constructing a large number of floor grouting reinforcement holes, cement slurry is injected into the holes to transform the aquifer into an impermeable layer or a weakly permeable layer, thereby ensuring the safety of mining. Taking the suburban coal mine as an example, about 500 floor grouting holes are required to be constructed each year. When the floor drilling construction is completed, the flange installed at the hole mouth needs to be removed and reused. Among them, the flange is referred to as flange, which is just a general term. It usually refers to a few fixed holes opened around a disc-like metal body for connecting other things. Because flanges are widely used in machinery, they look strange. As long as they look like them, they are called flanges. Flanges are parts that connect pipes to each other, connected to the pipe ends, with holes on the flanges, and bolts to tightly connect the two flanges. Flanges are sealed with gaskets. Flanges are disc-shaped parts and are most common in pipeline engineering. Flanges are used in pairs. In pipeline engineering, flanges are mainly used to connect pipelines. At the ends of two pipes that need to be connected, a flange is installed on each end. Threaded flanges can be used for low-pressure pipelines, and welded flanges can be used for pressures above 4 kg. Gaskets are added between the two flanges and then fastened with bolts. Flanges of different pressures have different thicknesses and use different bolts.

[0003] A Chinese patent discloses a flange separation auxiliary device (authorization announcement number CN 215660048 U). This patented technology can solve the problems that the existing pneumatic pick removal method will cause serious deformation of the flange, making it difficult to reuse the flange and causing the flange to be scrapped, increasing the number of scrapped flanges and also increasing the cost of flange removal.

[0004] The existing flange lacks a fixing structure when it is disassembled, which causes the flange to easily rotate relative to the flange and is inconvenient to disassemble flanges of different structures. Utility Model Content
