Oversized single-leaf protection airtight separation door for single-tunnel double-line section of metro

Abstract

Provided is an oversized single-leaf protection airtight separation door for a single-tunnel double-line section of a metro. A door leaf is of a single-leaf structure and is arranged in the single-tunnel double-line section or a double-line tunnel of the metro. A closed lock comprises a vertical output shaft, a transverse connection rod, a locking head connection plate, locking heads on two sides, a top locking head lifting mechanism, a top locking head, a sealing beam lifting mechanism, a hand-operating mechanism and a locking head seat. The vertical output shaft is connected with the transverse connection rod through a linkage mechanism. The linkage mechanism comprises a connection piece, a rotating arm and a crank handle connection rod. The top locking head lifting mechanism comprises a J-shaped rocker and a locking head connection rod. The sealing beam lifting mechanism comprises a reversed-J-shaped rocker and a sealing beam connection rod. The protection airtight separation door is applicable to separation of sections of air-defense construction of urban underground rail transit with one tunnel provided with two lines, ensures wartime use safety of single-tunnel double-line sections or double-line tunnel sections with small line distance, and has the advantage of being simple in manufacture and low in manufacture cost.

Description

technical field [0001] The invention relates to a protective airtight partition door installed in a subway single-hole double-track section or in a double-track tunnel in a subway project. Background technique [0002] Urban rail transit is an important part of modern urban public transportation. Urban rail transit projects are usually underground traffic arteries. In wartime, they are not only evacuation arteries for urban civil air defense, but also can be used as personnel shelters. When attacked by nuclear weapons, chemical weapons, and conventional weapons It can guarantee the safety of personnel and equipment under the urban secondary disaster after the attack, and can improve the comprehensive protection ability of the whole city. [0003] The underground urban rail transit project after fortification is a large-scale civil air defense project composed of many stations connected by section tunnels. Protective airtight partition doors that can withstand shock wave loa...

Problems solved by technology

[0005] The purpose of the present invention is to provide a super-sized single-leaf protective airtight partition door in the single-hole double-line section of the subway, to solve the problem that the traditional protective airtight partition door cannot be placed in the single-hole double-line section of the subway or the double-line tunnel section with a small line spacing The effective implementation of the partition at the place, so as to ensure the safety of a section in peacetime and wartime use
