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 ...
