Active auxiliary clamping device in the door system of high-speed railway vehicle
The utility model relates to a kind of active auxiliary clamping device that is located in the door system of high-speed railway vehicle, belong to the railway field of transport machinery.
The passenger train stopping sliding door is the railway passenger train passenger passage of train up and down, and the reliability of stopping sliding door and security relationship are to the normal operation of train and passenger's safety.At present the seal style of domestic common Automatic Plug Doors adopts single lip seal substantially, the rigidity of door leaf, sound insulation, heat insulation also just at quasi high-speed following vehicle design.For high-speed railway passenger, owing to aerodynamic reason makes vehicle propose the harsh more requirement except safety and reliability to door system door system, also sealing property, sound insulation value, the heat-proof quality of door system are had higher requirement, to guarantee the driving comfort of high speed train.
Summary of the invention
The purpose of this utility model is the defective at above-mentioned existence, proposes a kind of active auxiliary clamping device of setting up in the front portion of door system of high-speed railway vehicle, but its actv. improves the sealing property and the safety performance of door system.Technical solution of the present utility model, its structure is that the piston rod of cylinder joins with the pulling hold-down arm, the pulling hold-down arm rotates counterclockwise around the hold-down arm rotating shaft respectively, make latch hook after the latch hook rotating shaft is rotated, compress the locking pin on the door leaf, thereby make and to be fitted in the sealing joint strip generation sufficient elasticity distortion on the seal trim strip all round and to guarantee sealing property pushing away before the door leaf, can also effectively prevent that the car door accident from opening this moment; When releasing compresses, promote hold-down arm by the piston rod of cylinder and clockwise rotate position to locating dowel pin around the hold-down arm rotating shaft, throw off the support to latch hook, latch hook goes back to by the torsion spring effect and gets out of the way locking pin.According to the environment needs, can change motor-driven into by air cylinder driven.Advantage: active auxiliary clamping device has been set up at the rear portion in system, has improved the sealing property of door system, has guaranteed the safety performance of door system.

The specific embodiment
Contrast accompanying drawing 1,2 drives load carrier 2 and is installed on the car body 1, bears the total weight of door leaf 7 after taking door frame and door leaf 7 is captiveed joint by it, and drives the action that door leaf 7 opens or cuts out along the door leaf path of motion of setting.By the slideway in the driving load carrier 2 and following oscillating arm mechanisms 8 combineds action of student portion, make door leaf according to the moving orbiting motion of plug roping.Close when putting in place when door, double-lip seal adhesive tape and peripheric sealing press strip 10 on the door leaf 7 fit tightly and produce elastic deformation; The synchronous locking device 6 of two point is closed at door leaf 7 and door leaf 7 is locked in correct perch after putting in place, and meanwhile auxiliary wedging device 9 also is in the wedging state provides relevant position constraint bearing capacity; Active auxiliary clamping device 3 further pushes away door leaf 7 forward after door leaf cuts out again and makes the double-lip seal adhesive tape of door leaf and the peripheric sealing press strip 10 that is installed on the car body fully fit tightly, and guarantees that the sealing property of door system meets the demands.By operating outer handling device 5, interior handling device 11, car door emergency unlocking device 12 to gating device 13 fire switch gate signals, gating device (DCU) 13 sends instruction after receiving switch door request signal, make to drive load carrier 2, active auxiliary clamping device 3, the synchronous locking device 6 of two point and carry out corresponding actions, thus finish door unlatching, close and the stretching out and regain of pedal automatically.Behind the closing of the door, door system retrains door leaf 78 some positions door leaf, and they are respectively that the last latch hook on the synchronous locking device 6 of two point, following latch hook hook the lock pin up and down on the door leaf respectively; Two latch hooks on two active auxiliary clamping devices 3 hook the locking pin up and down on the door leaf respectively; Roller on two auxiliary wedging devices 9 inserts in the wedge; Take door frame and door leaf 7 is rigidly connected; In the guide rail of the roller of following oscillating arm mechanisms 8 and door leaf 7 bottoms door leaf is produced constrained force.Can guarantee door system reliability and safety by above constraint.
Contrast accompanying drawing 3, its structure is that all round sealing joint strip on the door leaf 7 fits together with seal trim strip 10 all round, the piston rod of cylinder 14 joins with pulling hold-down arm 16, pulling hold-down arm 16 rotates counterclockwise around hold-down arm rotating shaft 15 respectively, locking pin on latch hook 17 and the door leaf 7 compresses, hold-down arm 16 clockwise rotates to the position of locating dowel pin 18 around hold-down arm rotating shaft 15, throws off the support to latch hook 17, goes back under the effect of latch hook 17 by torsion spring 19 and gets out of the way locking pin.Active auxiliary clamping device 3 is pressing mechanisms of door system.When door leaf cuts out and after locking puts in place, active auxiliary clamping device 3 further promotes door leaf 7 forward, can make all round sealing joint strip on the door leaf 7 fit better, guarantee on sealing joint strip on the door leaf 7 and the car body back seal press strip enough compress variations to be arranged and the sealing property that improves door system with seal trim strip 10 all round.After door leaf 7 cuts out, the piston rod withdrawal of cylinder 14, pulling hold-down arm 16 rotates counterclockwise around hold-down arm rotating shaft 15, the locking pin that latch hook 17 is promoted on the door leaf 7 fully compresses car door, make to be fitted in the sealing joint strip generation sufficient elasticity distortion on the seal trim strip 10 all round and to guarantee sealing property, can also effectively prevent that the car door accident from opening this moment.When opening the door, system stretches out the piston rod of cylinder 14, promotes hold-down arm 16 and clockwise rotates to the position of locating dowel pin 18 around hold-down arm rotating shaft 15, throws off the support to latch hook 17.Latch hook 17 rotates counterclockwise releasing to the compressing of locking pin under the effect of torsion spring 19, door leaf 7 can be opened.According to the requirement of environment for use, can select cylinder or motor-driven.
Based on gating device (DCU) 13 action of control gate all-sidedly and accurately of microprocessor, finish the detection of safety protection function such as disturbance of intelligence, door isolation monitoring, degraded mode function, vital circuit etc. simultaneously.The electronics door control unit also has automatic fault supervision, diagnosis and function of reporting.Diagnostic program can be discerned dissimilar faults, and a record fault data different in periodical duty, and the number of times of these faults appearance are convenient to the sense cycle fault.The data of these records can also pass to Vehicle Information System or download to carries out failure analysis in the PC.The network communication type that gating device (DCU) 13 is supported has MVB, CAN, and RS485, LON and ISO3309/4335 etc. pass to Vehicle Information System with the fault data of comprehensive door status information and record.So that the driver in time suitably handles according to state and failure condition when the Qianmen.
