But in the use of non-pressure damper, find, pedestrian lane non-pressure damper uses normal, and the lane non-pressure damper that is open to traffic is broken by vehicle often, and the non-pressure damper that breaks is difficult to maintenance, the lighter's distortion, weight person can not normally use, and this not only will drop into lot of manpower and material resources non-pressure damper is safeguarded, has also had a strong impact on the stable of system.When non-pressure damper can't be realized complete atresia, often cause the twice air door semi-open, easily form distinguished and admirable short circuit.
On February 7th, 2007, the Chinese patent 200620023433.X of bulletin provided a kind of pneumatically-locked non-pressure damper, it is made of doorframe, door leaf, door-hinge, cylinder and appendix, described doorframe links together with the sealing frame, is provided with weather strip between sealing frame and the door leaf; Door-hinge places a side of door leaf opening direction respectively; One in described cylinder is fixed on the doorframe and links to each other with door leaf, and another is fixed on the doorframe of another road air door and links to each other with mechanical lock, connects with appendix between two cylinders.Keep minimum clearance between door leaf of the present utility model and the doorframe.Folding with door leaf is that power drive steam-cylinder piston reciprocating motion driving device lock is realized pneumatically-locked simultaneously.When one air door opened, another road air door locking simultaneously; After one air door closed, another road air door can release.That is: when the twice air door was closed simultaneously, air door was in released state; As long as there is a door leaf to open, just can realize the complete atresia of twice air door.This product structure is simple and practical, good seal, and locking is reliable, is the desirable air door that uses under the coal mine.But there are same problem in this non-pressure damper and existing non-pressure damper, promptly occur the problem that air door can't be opened after collision easily.Trace it to its cause, the overwhelming majority is because of having little time not in place the causing of opening the door or open the door.
The utility model content
The purpose of this utility model provide a kind of vehicle by precedingly can open automatically, vehicle pass through after closed voluntarily automatic control non-pressure damper.Solve existing non-pressure damper and the problem that the non-pressure damper that occurs because of Vehicular impact can not locking occurred easily.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of automatic control non-pressure damper, the sliding door that comprises air door, it is characterized in that described automatic non-pressure damper comprises pyroscan, scavenging air valve and driving cylinder, pyroscan links to each other with the scavenging air valve gauge tap that drives cylinder by power supply unit, drives the keying that cylinder links to each other with the sliding door of air door and controls sliding door.
Described pyroscan links to each other by the power supply box signal collector with the scavenging air valve gauge tap, and the power supply box signal collector also is connected with hand switch.
On the sliding door side lane wall of described air door slideway is installed, the movable slider of cooperation is set in the slideway, described driving cylinder is fixed on the wall of the other lane of slideway, and the piston that drives cylinder is connected with slide block, is connected with wire rope between the sliding door of non-pressure damper and slide block.
Former and later two admission valves of described driving cylinder are connected with the air inlet/outlet conducting of scavenging air valve respectively, the high-pressure air hose downlink connection in described scavenging air valve and the tunnel.
As pedestrian or vehicle through out-of-date, the pyroscan received signal, and signal passed to signal collector in the power supply box, the signal collector processing signals is also controlled the scavenging air valve action, the air valve that pushes away of scavenging air valve is opened, and drives cylinder and promotes the cylinder piston acting, moves along slideway thereby drive slide block, wire rope drives air door and opens, and finishes and opens the non-pressure damper action.After personnel or vehicle pass through, scavenging air valve is according to the shut-in time automatic reverse of setting, the getter valve of scavenging air valve is opened, pushing away air valve closes and discharges residual air, the piston that gas will drive cylinder pushes back in the cylinder body, and non-pressure damper is closed automatically by the gravity that self weighs down top, finishes non-pressure damper automatic switch process, this has also been avoided making air door turn-off transient bump fierce especially because of non-pressure damper weighs down the acceleration of gravity that top caused simultaneously, damages non-pressure damper.
Hand switch is connected with the power supply box signal collector, can directly control the unlatching and the ventilation action of scavenging air valve, when inoperative or sealing is used when Infrared Detectors, but the direct control hand switch, one door opening, the Switching Power Supply of another road air door is cut off, and can't operate, after this non-pressure damper is closed, another road air door switch recovers power supply, can normally use, thereby realize non-pressure damper locking effect, stop the problem that the twice air door is opened simultaneously.
