Embodiment Construction
[0038] The present invention will be further described below in conjunction with accompanying drawing.
[0039] Such as Figure 1-19As shown, a lifting type subway anti-flooding protective airtight door with a driving device under the present invention includes a door body, a hoisting type opening and closing device 15, a baffle trolley system 14, a guide wheel device, a squeeze wheel system 37, Press down mechanism, sealing device, drain valve device 27, gutter baffle plate 28 and electric control system constitute. Wherein, the door body includes a door leaf 1 and a door frame 2; the winch type opening and closing device 15 is used to control the rising and falling of the door leaf 1. The hoisting type opening and closing device 15 is connected with the door leaf 1 by a wire rope, and the hoisting type opening and closing device 15 and the door leaf 1 are also provided with the baffle trolley system 14, which is driven by an electric push rod. The pressing mechanism is pla...

The invention relates to a lifting type metro flood protective closed door with an underneath type drive device. The lifting type metro flood protective closed door with the underneath type drive device belongs to the technical field of protective closed partition doors, and comprises a door body, a winch type opening and closing device, a baffle plate car system, a guide wheel device, an extrusion wheel device, a pushing mechanism, a seal device, a water escape valve device, a drainage ditch baffle plate and an electric control system. The winch type opening and closing device is mainly formed by an opening and closing machine and a perpendicular jacking device; the perpendicular jacking device comprises two sets of hook devices and ropes; and the opening and closing machine comprises two sets of winding drum devices, a non-standard jacking speed reducer, a jacking brake motor and a synchronizing shaft. The lifting type metro flood protective closed door with the underneath type drive device provided by the invention better meets the requirements of the lifting type metro flood protective closed door with the underneath type drive device on a space, a dead load and a hydraulic door closing force, a hydraulic drive device can be synchronously opened and closed, the occurrence of the problem of stress imbalance caused by different upper and lower drive forces of the closed door is prevented, and the lifting type metro flood protective closed door with the underneath type drive device has a better application prospect.
Description
technical field [0001] The invention relates to an airtight door, in particular to an up-and-down subway anti-flooding protective airtight door with a driving device under it, and belongs to the technical field of rapid rail transit engineering protection. Background technique [0002] The subway is an important part of modern urban public transportation. The subway project is usually an underground traffic trunk line. In wartime, it is not only the evacuation trunk road for urban civil air defense, but also can be used as a personnel shelter. , to ensure the safety of personnel and equipment, and to improve the comprehensive protection capabilities of the entire city. In normal times, the stations are connected to each other by section tunnels. In wartime or flooding, partition gates that can withstand shock wave loads and prevent floods at the same time are installed to separate the tunnels between stations to form independent protection units. [0003] The underground ra...
