Problems solved by technology

[0005] In order to solve the technical problems existing in the background technology, the present invention proposes a novel underground refuge chamber protective airtight door, which is simple in structure, convenient in operation, low in production cost, and improves the flame retardant sealing effect and impact resistance strength of the door body. When the door body is deformed by the impact force, there will be no phenomenon that the door body cannot be opened

Abstract

A new protective airtight door for an underground refuge chamber proposed by the present invention includes a door body and a door frame. In the door frame, one side of the door body is hinged on the door frame, and the second L-shaped steel is provided with a plurality of locking clips connected with the door frame, and the locking clips are connected with the gear locking transmission mechanism on the door body through a connecting rod. Under the action of the gear transmission mechanism, the connecting rod fastens the locking clip on the door frame so that the flange on the door body is offset against the first flame-retardant sealing ring, and the first L-shaped steel material of the door frame is offset against the second flame-retardant sealing ring. . The invention has the advantages of simple structure, convenient operation and low production cost, and can resist explosion impact, high temperature and poisonous and harmful gas to the outside, and plays a vital role in realizing rescue.

Description

technical field [0001] The invention relates to the technical field of underground refuge chamber manufacturing, in particular to a novel protective airtight door for underground refuge chambers. Background technique [0002] In the process of coal mine production, there are always threats from objective factors such as water, fire, gas, coal dust, and roofs underground. Some mines also have new dangerous and harmful factors such as geothermal heat, corrosive substances, and radioactive substances. These areas may have high temperature, high humidity, high dust flying, high gas concentration, corrosive gas, many disaster-causing factors, high risk level, and the risk of catastrophic accidents is very high. [0003] The interim regulations issued by the state on the construction and management of emergency avoidance systems in coal mines are formulated in accordance with the spirit of the "Notice of the State Council on Further Strengthening Enterprise Safety Production Work"...
