Metro inter-zone flood-preventing protective air-tight gate opened and closed in swing mode

Abstract

The invention relates to a metro inter-zone flood-preventing protective air-tight gate opened and closed in a swing mode. A hinge pin is installed on a support on the gate. A swing hydraulic cylinder is installed on a machine rack. A push rod is provided with a clamping groove in the length direction. The hinge pin is connected in the clamping groove in a sliding mode. One end of the push rod is connected with a rotary shaft of the swing hydraulic cylinder. A supporting device further comprises an upper oblique plate, a lower oblique plate, a bolt, a base and a screw. The base is fixed on the ground under a wheel when a gate leaf is completely opened. The wheel is matched with the top of the upper oblique plate. The upper oblique plate is vertically and movably installed in the base and provided with an upper oblique plane. The lower oblique plate is horizontally and movably installed in the base and provided with a lower oblique plane. The upper oblique plane makes contact with the lower oblique plane. The lower oblique plane is in threaded connection with the screw. The bolt is installed on the base and matched with the upper oblique plate. The metro inter-zone flood-preventing protective air-tight gate opened and closed in the swing mode is simple in structure, small in occupied space and convenient to install and maintain and can be operated and controlled in manual and electric modes.

Description

technical field [0001] The invention relates to an anti-flood protection airtight door for a subway civil air defense project, in particular to an airtight door for anti-flooding protection in a swing opening and closing subway section. Background technique [0002] At present, a considerable number of tunnel projects (such as subways and river-crossing tunnels) still use traditional manual operation methods for the opening and closing, locking, support locking, etc. . Among them, the traditional method of opening and closing the anti-flooding protection door is mainly manual control through the gear transmission mechanism or the worm gear transmission mechanism, the speed of opening and closing the door is also slow, and automatic and remote control cannot be realized; secondly, the anti-flooding protection The traditional locking operation in the door is also mostly manual operation. For example, a locking mechanism disclosed in Chinese patent ZL 9924438.6 realizes the lo...

Problems solved by technology

Among them, the traditional opening and closing method of the anti-flood protection door is mainly to realize manual control through a gear transmission mechanism or a worm gear transmission mechanism, and the speed of opening and closing the door leaf is also slow, and automatic and remote control cannot be realized; secondly, the anti-flood protection The traditional locking operation in the door is also mostly manual operation mode, as a kind of locking mechanism disclosed in Chinese patent ZL 9924438.6 is exactly to realize the locking of door leaf by manually turning the handwheel, can't realize automatic control and remote control equally; The full-open locking of the protective door still mostly adopts the scheme of locking after manual operation of the screw jack, which has the disadvantages of time-consuming and manual operation

[0003] In view of the above existing problems, the patent CN 101666197A proposes an operating system that hydraulically drives the folding push rod and then opens and closes the anti-flooding protective door, which realizes the manual and electric dual-purpose and remote control of the opening and closing, locking, and support locking of the anti-flooding protective door However, in the application, it is found that the control system still takes up a lot of space, especially the opening and closing device of the anti-flooding protective door, which is composed of a folding push rod group, a hydraulic cylinder assembly, a hydraulic cylinder support assembly and a frame , and the mechanism is relatively complicated; at the same time, the patent CN 201531179 U proposes an elastic support device suitable for this type of anti-flooding protective door and a locking device that can be used manually and electrically At the same time of stability, it also realizes the automatic remote control of the full-open position locking and opening of the anti-flood protection door, but it is found in the application that the structure of the device is relatively complicated
