Abstract

The invention discloses a coal mine down-hole air sac type airtight cabin door, which relates to mining equipment. The cabin door comprises a door frame, a door leaf, hinges, a lock bolt, a lock sleeve, a sealing ring and a door handle, wherein an inner door frame is an annular sleeve which is formed by mutually connecting a semi-circular upper end, a semi-circular lower end, a linear left side and a linear right side; the door leaf is an annular sleeve which is formed by mutually connecting an arc-shaped door edge with a strip-type door edge and has the same shape as the inner door frame; the lock bolt is arranged on the door leaf through a guide rail and is hinged with a connecting rod I; the connecting rod I is hinged with a connecting rod II; the connecting rod II is hinged with the door handle; the door handle is an L-shaped rod piece; the joint of the L-shaped rod piece is hinged with the door leaf through a handle shaft; a U-shaped groove is manufactured on the outer sides of the arc-shaped door edge and the strip-shaped door edge; the sealing ring is arranged in the U-shaped groove and is a hollow rubber ring; an inflating valve is arranged on the sealing ring and is connected with a high-pressure gas tank through a gas conveying pipe and a pressure regulating valve; and the high-pressure gas tank is arranged on the door leaf and is reliably sealed.

Description

technical field [0001] The invention relates to coal mine equipment, in particular to an air bag-sealed hatch for underground coal mines. Background technique [0002] Airtight doors are the main protective equipment used in coal mines to prevent sudden accidents such as gas and water penetration. A waterproof airtight door should also be installed between the underground substation and the pump room. In the event of a water seepage accident, the airtight door can protect the electrical equipment of the substation from damage. The gunpowder depot under the coal mine is used to store gunpowder. The powder depot is very close to the parking lot and the main transportation avenue. There is a large amount of explosives stored in the depot. Once an accident occurs, it will cause serious casualties and losses. Therefore, sealed hatch doors must be installed at the two exits of the underground gunpowder storehouse and the underground distribution chamber, and the hatch doors are...
