Description
Technical field
The present invention relates to closed guard gate's technical field, specially a kind of tunnel that is based on is with drag reduction closed guard gate.
Background technique
With the development of domestic city urban rail transit construction, rigid suspension catenary is because of its low cost, structure is simple, installation
The advantages that easy to maintain and be widely used: to save the area, develop convenient for city integrated planning, rail traffic is generally located on ground
Under, civil air defense constructions and installations is combined, so special circumstances ought be encountered by being both needed to setting closed guard gate in places such as rivers two sides, tunnel faces
When, the closed guard gate in quick closedown tunnel is needed, to ensure tunnel and personnel safety.
Closed guard gate working method subway closed guard gate by motor carries out operation control after being installed in place, when encountering special circumstances
When, closed guard gate is closed by control system, reduces the coverage of accident.According to manner of execution difference, closed guard gate generally divides
For two kinds of forms: the form that flat-open type refers to is the form of normal domestic door, and side has branch hinge to be connected with basis, usually people's air defense
Door rests in the side in tunnel, is controlled when needing by hydraulic starting and closes and open.
Promotion refers to that form closed guard gate promotes and be locked in tunnel upper, and at closing time, closed guard gate leads under grain along gate slot
Tunnel face is dropped down onto, in emergency circumstances forces to close the door using closed guard gate's gravity, currently, in domestic project, concerning general in tunnel
It is made reference using being opened flat.
And improved in document primarily directed to closed guard gate involved in tunnel, first examines according to air pressure in tunnel
Consider: station-arrival of subway train and it is outbound when generate wind, and arrive at a station with it is outbound when wind direction be opposite (the train base made a return journey
On this that tunnel plug is tight, subway tunnel is equivalent to the shell of a syringe herein, and train is equivalent to infuse
Rubbery stopper in emitter, the train made a return journey at a high speed, which can push away, carrys out or siphons away a large amount of tunnel air, these are pushed away to inhale at a high speed
The movement that the air gone is done is formed the subway tunnel wind that we are felt) presence of this problem results in, closing
When closed guard gate, normal switching-off is not achieved in the speed that unidirectional closed guard gate closes, and according to the worry that sets the exam of closing the door against the wind, arranges in tunnel
Vehicle is both ends against opening and closed guard gate needs to need to prune at the top of closed guard gate in view of contact net system in the design
A part keeps away and touches contact net system, damages to contact net, and contact net, door body and tunnel face three are being closed
When, inevitable just to will appear gap, remain unchanged existing defects in sealing.
Summary of the invention
