The specific embodiment

As shown in Fig. 1~10, a kind of rail vehicle partition wall emergency unlocking device, comprise operation assembly and urgent shifting block assembly, the operation assembly comprises handle 1 and lever 3, lever 3 is fixed on partition wall by rotational pin, handle 1 is arranged on the laborsaving end of lever 3, and the other end of lever 3 is connected with backstop 4 by stay cord 2.Handle 1 is positioned at the outside of door separation, and the miscellaneous part of rail vehicle partition wall emergency unlocking device is positioned at the inboard of partition wall.

Urgent pulling block assembly comprises dead axle 7, stopper 6 and backstop 4, backstop 4 and stopper 6 are sleeved on dead axle 7, backstop 4 and dead axle 7 are by key and keyway up and down linear slide cooperation, key and keyway are separately positioned on dead axle 7 and backstop 4, stopper 6 and dead axle 7 are rotatably assorted, backstop 4 is pressed on stopper 6 by flexible member, and flexible member is stage clip 5.Have on stopper 6 by the mode of rotation and remove the stop block structure that blocks to the dead bolt 9 of the door lock of emergency escape door, have with the backstop 4 straight line reseting movement under the flexible member effect and be converted to the spiral camber 10 of the spinning reduction motion of stopper 6 on the contact end face of stopper 6, high order end one side of spiral camber 10 has spacing block set 11, low order end one side at spiral camber 10 has limited impression 12, and the contact end face structure of backstop 4 coordinates with the end face complementary structure that contacts of stopper 6.

Have two mount pads 8 on dead axle 7, below and this mount pad 8 that one of them mount pad 8 is positioned at stopper 6 are fixedly connected with the end of dead axle 7, have slot to make way in the side of backstop 4, and another mount pad 8 is by slot to make way and dead axle 7 welding.

The cross section with the stopper 6 of stop block structure of the present embodiment, as shown in Figures 9 and 10, its cross-sectional shape comprises segmental arc and the straightway that is connected the segmental arc end points, have the dead axle hole in segmental arc and straightway institute region, when stopper 6 was in initial position, straightway was parallel with dead bolt 9, block dead bolt 9, after stopper 6 half-twists, straightway is vertical with dead bolt 9, has removed blocking dead bolt 9.

Under normal circumstances, the stopper 6 in urgent shifting block assembly is blocked dead bolt 9, and the spacing block set 11 of stopper 6 embeds backstops 4, and 6 rotations of restriction stopper are promptly set ahead and locked door separation together with the door lock of assembly and door separation.

the passenger is at the vehicle unregulated power, aerodynamic force in emergency circumstances by manually pulling the handle 1 in this emergency unlocking device, handle 1 pulls backstop 4 in the urgent shifting block assembly of being located at the partition wall middle part by lever 3 through rope 2, make spacing block set 11 and backstop 4 break away from, stopper 6 in urgent shifting block assembly is in the situation that the pretightning force that yielding rubber provides when closing by door separation without backstop 4 lockings makes stopper 6 around dead axle 7 half-twists, thereby the door separation that makes back, train driving chamber is opened automatically losing under corresponding stopper 6 effects, the passenger just can be by being located at the emergency escape door escape of train front end like this.After the passenger unclamped handle 1, the stage clip 5 in urgent shifting block assembly promoted backstops 4 and moves down, thereby the lower end of backstop 4 acts on and promotes stopper 6 on the spiral camber 10 of stopper 6 and reset around 90 ° of dead axle 7 revolutions, again the dead bolt 9 on door separation is formed and blocks.While stopper 6 is under normal circumstances locked by backstop 4, can't rotate, and the assurance door separation can not opened because of passenger's dependence, and the crew can open door lock on door separation by key, make dead bolt 9 retractions of door lock, can remove equally the locking to door separation, open door separation.
