AI Technical Summary
The existing integrated steel plate anti-shock door is inconvenient to maintain during use, resulting in high production costs. When there is a bottom drum in the tunnel and a top pressure, the damper cannot be closed or closed tightly.
A top-down detachable anti-shock door is designed, and the rapid disassembly and maintenance of the damper is achieved through iron plates arranged in the vertical direction and a removable and connected wooden structure.
This design reduces the number of maintenance workers, reduces production costs, and can close the damper normally by dismantling the wooden side when the tunnel has a kick drum and top to press.

Abstract
Description
Technical Field
[0001] The utility model relates to an upper and lower detachable anti-burst air door, belonging to the technical field of safety prevention and control in coal mines. Background Art
[0002] Mine anti-gas outburst damper is the abbreviation of coal mine gas outburst automatic damper or mine anti-gas outburst damper; it is widely used as a damper for safety protection measures when excavating coal seams in mine shafts or in mining operations. Anti-gas outburst dampers are generally made of iron steel damper materials, with a total of 2 dampers in a set, each with a forward damper and a reverse damper, that is, two dampers are installed in the same connecting tunnel (i.e. two forward dampers and two reverse dampers).
[0003] When a gas outburst occurs at the working face, the high-energy gas flow that gushes out instantly has the characteristics of high concentration and abundant source. The anti-outburst door can prevent the high-concentration gas generated by the outburst from flowing back into the fresh air flow, which to a certain extent prevents the expansion of the impact range of the gas outburst and cuts off the momentum of rapid spread in the return air direction.
[0004] The existing anti-blowout dampers in a certain mine are integral steel plates. In actual on-site use, when bottom drum or tunnel roof pressure occurs, a large amount of manpower and material resources are required each time to demolish the wall to renovate the anti-blowout dampers, which is inconvenient to maintain and has high production costs. Utility Model Content
[0005] The technical problem to be solved by the utility model is to provide an upper and lower detachable anti-burst air door to solve the technical problems existing in the above-mentioned prior art.
[0006] The technical solution adopted by the utility model is: an upper and lower detachable anti-burst wind door, comprising an iron plate arranged in a vertical direction, wherein a horizontal door belt is fixed to the upper and lower parts of the iron plate respectively, and the upper end of the iron plate and the lower end of the iron plate are detachably connected with a first wooden square and a second wooden square respectively.
[0007] Preferably, the door belt is fixed to the iron plate by bolts.
[0008] Preferably, the number of the first wooden blocks and the number of the second wooden blocks are both set to be more than one.
[0009] Preferably, the height of the first wooden square is set to 15-25 mm.
[0010] Preferably, the height of the second wooden square is set to 40-60 mm.
[0011] Preferably, the first wooden square at the bottom is nailed to the upper end of the iron plate, and the second wooden square at the top is nailed to the lower end of the iron plate.
[0012] Preferably, the upper end surface of the first wooden square is provided with a first strip-shaped through groove arranged along the extension direction of the first wooden square, and the lower end of the first wooden square is provided with a first protruding column matched with the first strip-shaped through groove.
[0013] Preferably, the upper end surface of the second wooden square is provided with a second strip-shaped through groove arranged along the extension direction of the second wooden square, and the lower end of the second wooden square is provided with a second protruding column matched with the second strip-shaped through groove.
[0014] Preferably, a handle arranged in a vertical direction is provided at the middle portion of the side of the iron plate away from the door belt.
[0015] The beneficial effects of the utility model: compared with the prior art, the utility model provides an upper and lower detachable anti-burst damper structure. When there is bottom drum and top pressure in the tunnel and the damper cannot be closed or closed tightly, the first wooden square or the second wooden square can be removed to make the damper close normally; and compared with demolishing the wall to renovate the damper, it can reduce the workload of employees, reduce the number of staff, and save production costs.
