Foldable rapid plugging device for trapezoidal roadway

Abstract

The invention relates to a foldable rapid plugging device based on a trapezoidal roadway. The foldable rapid plugging device comprises a telescopic main body frame, foldable fireproof plates and a control center. The foldable fireproof plates are arranged on the two sides of the main body frame. After the main body frame extends and the foldable fireproof plates are unfolded, the device clings tothe side wall of the trapezoidal roadway, so that the trapezoidal roadway is plugged up. The main body frame comprises telescopic stand columns and pipe fittings hinged between the stand columns in acrossed mode. Each telescopic stand column is a stand column of a three-level telescopic structure so as to adapt to roadways of different heights. Moving wheels are arranged at the bottoms of the stand columns of the main body frame. A reel fire protection device is movably connected with the outer portion of each telescopic stand column. The foldable fireproof plates are symmetrically connectedto the two ends of the main body frame, and each foldable fireproof plate comprises a fixing block, a fireproof top plate, a fireproof bottom plate, fireproof side plates and a supporting device. Thefoldable rapid plugging device is light, resistant to high temperature, safe and reliable.

Description

technical field [0001] The invention belongs to the technical field of coal mine production safety, and in particular relates to a folding-type rapid sealing device for a trapezoidal roadway. Background technique [0002] Coal is mined in a backward style. After mining, a goaf is formed. Oxygen enters the goaf due to external cracks, and the remaining coal in the goaf spontaneously ignites. In order to cut off the air in the roadway and enter the gob, it is necessary to prevent a large amount of mining coal combustion and gas from entering. Explosion occurs, causing coal loss and accidents, so a blocking device is needed to block the goaf. And the existing blocking method is to use wooden boards to build baffles to block the entrance of the roadway, and then use single pillars to fix and support the wooden boards. After the concrete is solidified, it is difficult to dismantle the original wooden planks, often destructively, and it is difficult to recycle the dismantled wood...

[0002] Coal is mined in a backward style. After mining, a goaf is formed. Oxygen enters the goaf due to external cracks, and the remaining coal in the goaf spontaneously ignites. In order to cut off the air in the roadway and enter the gob, it is necessary to prevent a large amount of mining coal combustion and gas from entering. Explosion occurs, causing coal loss and causing accidents, so a blocking device is needed to block the goaf

And the existing blocking method is to use wooden boards to build baffles to block the entrance of the roadway, and then use single pillars to fix and support the wooden boards. After the concrete is solidified, it is difficult to dismantle the originally built planks, often destructively, and it is difficult to recycle the dismantled planks, and there is no special sealing device for trapezoidal roadways
