Description

Technical Field

[0001] The utility model relates to the technical field of direct application, in particular to a self - moving airbag leakage - plugging device for the upper and lower ends of a coal - mining face. Background Technique

[0002] At present, for plugging air leakage at the upper and lower ends of a coal - mining face, methods such as constructing bag walls and hanging air curtains are mostly used. The bag walls are mostly constructed by stacking woven bags filled with loess (or coal). Given that the surface of some mines is grassland or cultivated land, it is difficult to obtain soil, and some mines use woven bags filled with coal for stacking construction.

[0003] However, there are the following problems. First, the safety risk is high. When personnel operate at the end, there are risks of roof fall and gas asphyxiation. Second, the risk of spontaneous combustion is high. It is not conducive to the caving of the roof, and a large amount of coal body remains in the goaf, which is not conducive to fire prevention and extinguishment. Third, the potential safety hazard is large. After the bag wall is constructed, it enters the goaf and supports the roof, causing a hanging roof in the goaf. Fourth, the construction cost is high. Taking the bag wall at the end of the working face as an example, each bag wall requires 16.6 tons of coal. Calculated at a coal price of 600 yuan / ton, the coal price is nearly 10,000 yuan. Considering the woven bags and labor costs, the cost of setting up each bag wall is nearly 17,000 yuan. Content of the Utility Model

[0004] The purpose of the utility model is to provide a self - moving airbag leakage - plugging device for the upper and lower ends of a coal - mining face to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A self - moving airbag leakage - plugging device for the upper and lower ends of a coal - mining face, including a roof. One side below the roof is provided with a roadway sidewall. Below the roof is provided with a hydraulic support. One side of the hydraulic support is provided with an airbag. The top of the airbag is provided with an airbag hanging and charging pipe. One side of the airbag hanging and charging pipe is provided with a high - pressure rubber hose. One end of the high - pressure rubber hose is provided with a charging and discharging block. Above the hydraulic support is provided with a support rod.

[0006] Preferably, an air inlet pipe is arranged on one side of the charging and discharging block, and an air inlet valve is arranged on one side of the air inlet pipe.

[0007] Preferably, an air outlet pipe is arranged on one side of the charging and discharging block, and an air outlet valve is arranged on one side of the air outlet pipe.

[0010] Preferably, a connection fixing block is provided on one side of the support rod, a rotating rod is provided on one side of the connection fixing block, and a connecting rod is provided on one side of the rotating rod.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] For the self - moving airbag plugging device at the upper and lower ends of a coal mining working face, through the arranged roof, hydraulic support, and airbag, the hollowed - out part of the mining area can be quickly filled, effectively avoiding the problem of a large amount of coal body remaining in the goaf. Through the arranged roof, roadway side, hydraulic support, and support rod, the hollowed - out area can be effectively supported to avoid the problem of the collapse of the entrance being blocked. When used in cooperation, it can effectively avoid the risk of gas asphyxiation and fire, and at the same time effectively avoid the problem of high internal risk after the construction of the bag wall.

[0013] For the self - moving airbag plugging device at the upper and lower ends of a coal mining working face, through the arranged roof, roadway side, hydraulic support, and support rod, an effective supporting space can be formed for the internal hollowed - out part, facilitating the filling operation of the staff. Through the arranged airbag, airbag hanging and charging pipe, high - pressure rubber hose, and air charging and discharging block, the inside of the hollowed - out part can be quickly filled.

[0022] Working principle: After the staff opens the mining area to form an internal space, a stable space is formed by the top plate 1, the roadway side 2, the hydraulic support 3, and the support rod 8. When it is necessary to fill the internal space, connect the air inlet pipe 9 to the air supply equipment, close the air release valve 12, open the air inlet valve 10, and the air supply equipment supplies air. The gas enters the charging and discharging block 7 through the air inlet pipe 9 and then enters the high-pressure rubber hose 6, and then inflates multiple air bags 4 through the air bag hanging air charging pipe 5. After the air bags 4 are inflated, the internal space is quickly filled, and the internal filling of the hollowed-out area of the mining area is completed.

[0023] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
