Description

Multi-functional flange pipeline connects ware of strutting Technical Field The utility model belongs to the technical field of coal mine tools, and particularly relates to a multifunctional flange pipeline joint spreader. Background According to the second hundred forty-nine of the regulations of coal mine safety, the mine must be provided with a ground fire-fighting water tank and a downhole fire-fighting pipeline system. The downhole fire piping system should be run to the mining face with branch pipes and valves set every 100m, but every 50m in the belt conveyor tunnel. And sixthly, arranging compressed air pipelines on disaster avoidance routes of mining areas, wherein the diameter of the main pipeline is not less than 100mm, the diameter of the pipeline of the mining working face is not less than 50mm, and the interval of air supply valves arranged on the compressed air pipelines is not more than 200m. The mine with complex hydrogeology condition and extremely complex condition should be laid with compressed air pipeline at the highest position of each horizontal, mining area and mountain-climbing tunnel, and set with air supply valve. The disaster-avoiding route of the mining area should be laid with a water supply pipeline, and a water supply valve is arranged near the air supply valve. According to the above specified requirements, the underground coal mine pipe network system has great effect, is related to life safety of vast coal mine workers, and has huge workload of underground coal mine pipeline installation and maintenance along with continuous development of large-scale national mines, and most underground coal mine pipelines in China are installed in a bolt fastening mode by matching a flange welded pipe with a rubber sealing gasket. In the use, rubber sealing pad receives reasons such as ageing, pressure, takes place to damage easily, and in the change process, because the clearance is too little between the pipeline joint, has the degree of difficulty to be big when changing sealing pad, and is consuming time long, the high scheduling problem of risk very influences the normal production in pit. If in an emergency situation, the life safety of coal mine workers is possibly endangered directly. Disclosure of utility model Aiming at the problems of high difficulty, long time consumption, high risk and the like in the conventional replacement of the rubber sealing gasket of the underground coal mine pipeline, the utility model provides the multifunctional flange pipeline joint spreader which is used for underground special replacement of the pipeline rubber belt so as to achieve the purposes of simplicity, time saving and labor saving in replacing the pipeline rubber gasket. The utility model adopts the following technical scheme: The utility model provides a multi-functional flange pipeline joint struts ware, includes that the cross-section is the frame that struts of U type, the top symmetry of strut the frame is equipped with the trompil first that corresponds with the bolt hole of ring flange, is equipped with the ejector pin that is used for strut the frame and is connected with the ring flange in the trompil first, the bottom of strut the frame is equipped with the through-hole, is equipped with the point of propping that is used for propping up the ring flange in the through-hole, and the bottom of propping up the point is equipped with the jack bolt, and the lateral wall of strut the frame is equipped with trompil second, is equipped with the stop bolt who plays spacing effect in the trompil second. Further, the through hole at the bottom of the expansion frame is positioned at the center of the expansion frame. Further, the cross section of the through hole at the bottom of the expansion bracket is elliptical. Further, a slot is formed in the side wall of the supporting tip, and a limit bolt penetrates through the slot. Further, one end of the supporting tip is a pointed cone end or a flat end or a groove end. The beneficial effects of the utility model are as follows: 1. the utility model has simple structure and convenient use. 2. By using the utility model, the pipeline rubber pad can be replaced in a time-saving and labor-saving manner. 3. By using the utility model, the flange fixing bolt can be broken and disassembled when the flange fixing bolt cannot be disassembled due to rust.
