An elevator-type subway section anti-flooding protective airtight partition door

Abstract

The invention relates to a lifter-type anti-flooding and protective closed partition door for a metro section. A driving device is connected with a door leaf to drive the door leaf to move relative toa door frame, and a safety device is connected to the door leaf so as to ensure that the door leaf is locked relative to the door frame after lifting in place, the safety device includes a safety motor, a lock head, a lock seat and a lifting ring, wherein the safety motor and the lock seat are installed and fixed on a supporting beam of the door frame, the safety motor is connected to the lock seat so as to drive the lock head to move horizontally, the lock seat includes a primary lock seat and a secondary lock seat which are arranged at intervals, and the lifting ring is fixedly connected with the top of the door leaf. In the state of non-lifting in place, the lock head only passes through the primary lock seat; and in the state of lifting in place, the lock head passes through the primary lock seat, the lifting ring and the secondary lock seat so as to lock the door leaf relative to the door frame. According to the lifter-type anti-flooding and protective closed partition door for the metro section, safety protection is provided by the safety device after lifting in place, so that the equipment use space is compressed effectively, and the engineering applicability is enhanced tomeet all standard station height conditions.

Description

technical field [0001] The invention relates to an orifice device for civil air defense, and more particularly relates to an elevator-type anti-flooding protective airtight partition door for a subway section. Background technique [0002] The anti-flooding protective airtight partition doors in the subway section can generally be divided into lifting type and vertical rotation type according to the direction of door movement. An existing lift-type partition door is hoist lift-type equipment, and the height of the door chamber needs to be no less than 8.7 meters. Another existing lifting type partition door is an electric hoist type, and the height of the door chamber needs to be at least 7.45 meters. These two heights are both greater than the standard net floor height of 4.9 meters for the station hall floor of the subway station, so its engineering adaptability is greatly limited. Therefore, in most cases, the vertical rotation equipment becomes the last choice. The se...
