Embodiment approach 1

[0021] like image 3 and Figure 4 Shown, the present invention is used for a kind of mine explosion-proof door inflatable temporary replacement device of shaft. The fixing device 2 is installed on the ground next to the wellhead of the shaft, and is composed of a beam 2-1, a support 2-2, a bolt 2-3, a pressure plate 2-4 and a nut 2-5, and the beam 2-1 passes through the pressure plate 2. -4. The bolt 2-3 and the nut 2-5 are fixed on the support 2-2. The cross-sectional shape of the multi-cavity airbag 1-1 is similar to that of the shaft, and the cross-sectional shape is approximately circular.

Embodiment approach 2

[0023] like Figure 5 and Figure 6 Shown, the present invention is used for a kind of mine explosion-proof door inflatable temporary replacement device for adit or inclined shaft. The fixing device 2 is installed on the ground. The cross-sectional shape of the multi-cavity airbag 1-1 is similar to that of the inclined shaft and the flat aisle.

[0024] The invention relates to an inflatable temporary replacement device for a mine explosion-proof door. When replacing the old explosion-proof door, stop the wind first, open the old explosion-proof door, then put the multi-chamber air bag 1-1 into the wellhead of the vertical shaft or the inclined shaft and the flat aisle, fix the rope net 3 on the fixing device, and pass the high-pressure gas through After the total air inlet 3-2 is filled with the air bag to the rated value, the ball valve 3-3 is closed, and then the fan is started for ventilation, and the explosion-proof door is replaced while normal production. After the ...

Abstract

The invention relates to an inflatable temporary replacing device for a mine anti-explosion door. The inflatable temporary replacing device comprises an air-charging device, a fixing device and a rope net, wherein the air-charging device is fastened on the fixing device through the rope net; the air-charging device comprises a multi-chamber air bag and an air path system; the multi-chamber air bag is composed of at least two air chambers which are independent from each other; each of the air chambers is provided with an air inlet and an air outlet; the air inlets of all the air chambers are collected into a head air inlet through the air path system; and the air outlets of all the air chambers are collected into a head air outlet through the air path system. The long-lasting serious problem that the safety rescuing and the production recovery cannot be timely performed because of the gas explosion of a mine well is solved; a quick and convenient temporary replacing device for exchanging the anti-explosion door of a mine ventilating system is supplied; the blowing-out time is reduced; and the economic loss caused by blowing-out and production halt is reduced.

Description

technical field [0001] The invention belongs to the technical field of explosion-proof doors, in particular to a temporary replacement device used for replacing explosion-proof doors in coal mine ventilation safety facilities. Background technique [0002] Existing coal mine ventilation safety facilities air shaft explosion-proof door, once an underground explosion occurs in the coal mine, the explosion-proof door is easily damaged or flies away from the wellhead, and the explosion-proof door cannot be reset in a short time, which will cause the coal mine to be unable to operate in the mine. Ventilation is restored in a short period of time, so that harmful gases cannot be discharged, and rescue personnel lose time for rescue and rescue. At the same time, it also seriously endangers the life safety of underground coal mine workers, resulting in the expansion of disasters after the accident. For this reason, coal mines urgently need to replace more safe explosion-proof doors ...
