The invention relates to a mechanical locking device which comprises a locking support, a rocker arm connected to the locking support and a door leaf support matched with the rocker arm, wherein the locking support comprises a baseplate, as well as a hinged support and a door-shaped position-limiting frame which are arranged on the baseplate; the door leaf support comprises a door leaf connecting plate and a rocker arm positioning support arranged on the door leaf connecting plate; the rocker arm is hinged and connected to the hinged support through a rocker arm shaft, the rocker arm and the rocker arm shaft are fixed circumferentially, the outer end part of the rocker arm is positioned in the door-shaped position-limiting frame, an outer-end upper side surface corresponding to a cross beam of the door-shaped position-limiting frame is further arranged on the upper side of the outer end part of the rocker arm, and an inner-end upper side surface corresponding to the rocker arm positioning support is arranged at the inner end part of the rocker arm; and a forward and reverse rotation motor is fixedly connected to the baseplate, and the output end of the forward and reverse rotation motor is connected with the rocker arm shaft through a gear transmission mechanism. The device is safe, reliable and simple in structure and can effectively solve the difficult problems of mounting and debugging of the mechanical locking device and further solve the problem that the traditional door leaf locking device is often jammed.
Description
technical field [0001] The invention relates to a door leaf locking device installed on a protective airtight and anti-flooding door of a subway section. Background technique [0002] According to the relevant provisions of my country's "Civil Air Defense Law", the construction of subway projects must take into account the needs of civil air defense during wartime. For subway projects, protective airtight and anti-flooding doors should be installed at appropriate positions at both ends of the waters entering and exiting the water area, or other anti-flooding measures should be taken. [0003] With the development of urban subway traffic, the subways currently under construction are all constructed with man-made air defense projects, and some lines involve passing through rivers or lakes and other waters, thus involving protective airtight and anti-flooding doors. For the protective airtight and anti-flooding doors set in the tunnel, the door leaf locking device designed on i...
