Description
Technical field:
The utility model belongs to the facilities for transport and communication technical field; Relate to the special-purpose formula that the automatically resets tripper of access door between the driver service depot and passenger accommodation in the rolling stock of the tripper that automatically resets, particularly a kind of quick operation that a kind of rolling stock access door uses.
Background technology:
At present; In normally used railway passenger train; In order to guarantee that the vehicle drive personnel have relatively independent operating space, operated by rotary motion has special-purpose access door and tripper thereof between drivers' cab and the passenger accommodation, and this is one of key factor that needs in the design of rolling stock safety vehicle the emphasis consideration; Require in case of emergency, the passenger can open access door through the operation emergency unlocking device and escape.Existing access door tripper majority does not possess auto-reset function, after the regular maintenance personnel of vehicle open access door from passenger accommodation, after needing manually tripper to be resetted, could recover the locking function of access door door lock; Its outstanding shortcoming is simple in structure, complicated operation, and inconvenience is used in manually-operated, maintenance difficult, automaticity is low.
Summary of the invention:
The goal of the invention of the utility model is to overcome the shortcoming that prior art exists, and seeking to design provides a kind of tripper that possesses auto-reset function, is used for closing automatically and resetting of rolling stock access door, has locking retaining and two kinds of basic functions of release.
To achieve these goals, the agent structure of the utility model comprises tripper, door-plate, doorframe, draws composition, lever composition, lever support, pull bar composition, release pulling block, baffle plate positioning sleeve, stage clip, mandrel and lock bolt retaining; Tripper is fixedly mounted on the door frame for vehicle, and cooperate corresponding with the latch fitting on the door-plate aligns; Fixedly be shaped on the doorframe top of vehicle and the frame place side and draw forming; Draw and fixedly be shaped on the lever composition on the upside forming; Lever is formed brace type and is fixed on the lever support; The end points place that lever is formed fixedly is shaped on the pull bar of the structure that hangs straight down and forms, and interconnection system fixedly is shaped on the release pulling block on the bottom end points that pull bar is formed; Release pulling block top is installed with the baffle plate positioning sleeve of nesting type structure, and the lower end of baffle plate positioning sleeve is shaped on the rigidity stage clip, and the lower end butt joint of stage clip is shaped on mandrel; The bottom end position of release pulling block is installed with the lock bolt retaining.
The utility model is installed on the doorframe of car door, is used with the lock that is fixedly mounted on the door-plate, and the operation under the normal condition slips in the gap of tripper and doorframe after the Door-lock bolt compression at closing time, realizes the reliable locking of car door; In case of emergency, draw forming through operation, under the effect of lever, the baffle plate positioning sleeve on the realization release pulling block separates with the lock bolt retaining, and the lock bolt retaining is in rotatable state, and its backstop function is eliminated, and realizes the driving door operation; Behind the car door opening, unclamp operation is drawn forming, and tripper relies on the interaction force of the screw fit face of baffle plate positioning sleeve and lock bolt retaining to reset under the influence of stage clip active force, locking retaining functional rehabilitation.
The utility model compared with prior art, its novel structure uses easy controlled operation, it is convenient that preparation is installed, soundness is good, the control automation is safe and reliable, is applicable to bullet train use in service.

Fig. 1 is the mounting structure principle schematic of the utility model.
Fig. 2 is the package assembly principle schematic of the utility model.
Fig. 3 is the release pulling block package assembly principle schematic of the utility model.
The specific embodiment:
Below through embodiment and combine accompanying drawing to be described further.
Embodiment:
The agent structure of present embodiment comprises tripper 1, door-plate 2, doorframe 3, draws composition 4, lever composition 5, lever support 6, pull bar composition 7, release pulling block 8, baffle plate positioning sleeve 9, stage clip 10, mandrel 11 and lock bolt retaining 12; The main body of tripper 1 is fixedly mounted on the door frame for vehicle 3, aligns with the latch fitting corresponding matching on the door-plate 2; Be fixed with on door frame for vehicle 3 tops and the frame place side and draw forming 4; Draw and fixedly be shaped on lever composition 5 on 4 upsides forming; Lever is formed 5 brace types and is fixed on the lever support 6; The end points place of lever composition 5 fixedly is shaped on the pull bar of the structure that hangs straight down and forms 7, and interconnection system fixedly is shaped on release pulling block 8 on the bottom end points of pull bar composition 7; Release pulling block 8 tops are installed with the baffle plate positioning sleeve 9 of nesting type structure, and the lower end of baffle plate positioning sleeve 9 is shaped on rigidity stage clip 10, and the lower end butt joint of stage clip 10 is equipped with mandrel 11; The bottom end position of release pulling block 8 is installed with lock bolt retaining 12.
The tripper 1 of present embodiment is fixedly mounted on the doorframe 3; During the closing of the door state, the arc surface compressing that the dead bolt on the door-plate 2 is unlocked on the device 1 is shunk, and the dead bolt on the door-plate 2 is arranged between doorframe 3 and the tripper 1; Be implemented in drivers' cab side actuating doors handle or key; Dead bolt is shunk, break away from tripper 1, realize opening the door action; In case of emergency; Under the passenger accommodation side direction, draw forming 4; Through the effect of lever composition 5 and lever support 6, power is delivered to pull bar forms on 7, make pull bar form 7 and move up; Overcome the pressure of the stage clip 10 in the release pulling block 8, baffle plate positioning sleeve 9 is slided and 12 disengagings of lock bolt retaining along mandrel 11; After baffle plate positioning sleeve 9 broke away from lock bolt retaining 12, lock bolt retaining 12 was in rotatable state, and when opening the door, the dead bolt on the door-plate 2 promotes 12 rotations of lock bolt retaining, breaks away from lock bolt retaining 12, realizes opening the door function; After opening the door; Unclamp and draw forming 4; Mandrel 11 and relies on the screw fit face of baffle plate positioning sleeve 9 and lock bolt retaining 12 to lower slider to baffle plate positioning sleeve 9 in the effect lower edge of stage clip 10 elastic force, is to make lock bolt retaining 12 recover the active force of normal bit with force transmission; Realize the reset function of lock bolt retaining 12, tripper 1 recovers normal condition.
