Description

Technical Field

[0001] The invention relates to a pneumatic punching device for a hanging clamp used in underground coal mines. Background Art

[0002] According to the safety standardization management requirements of coal mines, underground pipelines need to be suspended with clamps. The underground pipelines are laid to cover all tunnels, the lines are long, and a large number of clamps are used. At present, hydraulic punching machines are used for processing on the ground, which require pumping stations to provide power, but the repair and maintenance costs of pumping stations are high, and they consume a lot of electricity, resulting in high overall production costs. The pneumatic punching device of the present invention is made of mining I-beams, high-pressure hoses, jacks, operating valves, etc., and is powered by the mine compressed air system. Local materials are used, the cost is low, and the operation is simple, safe, energy-saving, and environmentally friendly.

[0004] The purpose of the present invention is to produce a hanging clamp pneumatic punching device for underground coal mines, which uses the mine compressed air system to provide power, improves processing efficiency, reduces costs, and is simple, safe, energy-saving, and environmentally friendly to use.

[0005] The implementation method of the present invention is as follows: a pneumatic punching device for hanging clamps used underground in coal mines is composed of a support frame, a jack and a mold. The support frame uses 9# mining I-beam as a frame and presents a gantry structure. A jack fixing device is arranged on the top and welded to the top of the jack; a jack supporting fixing device is arranged in the middle and welded to the middle of the jack; a support frame base and a mold seat are arranged at the bottom, and the mold seat is also made of 9# mining I-beam, and 10mm steel plate and 50×50mm angle iron reinforcement are used for the main parts; jack: the top of the jack is welded to the jack fixing device of the support frame, and the lower part is welded to the lower mold; the mold is divided into an upper mold and a lower mold, the upper mold is made of 100mm round steel, and a pressure plate is welded in the radial direction, and the pressure plate is processed by 10mm steel plate; the lower mold is made of 10mm steel plate, welded into a 400mm×200mm box-type, half of the steel pipe is nested inside, and the lower mold is welded to the mold seat as a whole.

[0006] The application method of the present invention is as follows: (1) Processing the pneumatic punching device of the present invention for the pipeline hanging clamp for underground coal mine. (2) Underground installation and use: Use KJ-10 type high-pressure hose to connect the jack air inlet joint and the return air joint, use the operating valve to control the air inlet and return air respectively, and connect the operating valve air source to the underground compressed air system. When processing the clamp, only the valve group needs to be operated to realize the rise and fall of the upper mold, and the finished product can be punched out by cooperating with the lower mold. BRIEF DESCRIPTION OF THE DRAWINGS
