But the operating principle accompanying drawings of rail traffic platform shield door locking-unlocking device of the present invention is following:
The locking Principle of Process of closing the door of the present invention is: when door opening state, left and right sides lock dog 21 is opened a business under the pulling force of lock dog back-moving spring 23, and break away from left and right sides dead bolt 22 this moment, as shown in Figure 2.When double door is closed; Be installed in the spacing pin 6 of left and right sides dodge gate on the double door and move to left and right sides dead bolt 21 and contact, continue motion and rotate, when turning to certain angle up to promoting dead bolt; When the lock dog underarm slips in the latch hook 221 of dead bolt; The resilience under the effect of dead bolt back-moving spring 24 of the ineffective power of dead bolt, lock dog underarm embed in the dead bolt, and this moment, the rotation of lock dog was limited.The spacing pin 6 of dodge gate moves to this moment, and dodge gate is closed stop motion, and the spacing pin 6 of dodge gate rotates in the flexure type notch 213 that is absorbed between the underarm in lock dog, thereby realizes locking.
The Principle of Process that release of the present invention is opened the door is: dead bolt trundle 33 and latch bolt spring pin 241 are installed on left and right sides dead bolt 22, and latch bolt spring pin 241 moves in corresponding mounting hole 11 restricted portions on lock 1; Simultaneously, the range of movement of dead bolt also is limited.On the spring catch 241 on the dead bolt dead bolt back-moving spring 24 is installed, dead bolt is in all the time and opens maximum rating under the tension of dead bolt back-moving spring 24.After lock dog slips into dead bolt, be in the lock state all the time, the pulling force that overcomes dead bolt back-moving spring 24 when dead bolt rotates with other resistance, throws off the lock dog underarm, and the restriction of lock dog underarm is disengaged.Power when the power that lock dog rotates mainly comes from the spacing pin 6 of dodge gate with the door folding, release is opened the door thereby lock dog rotates realization under the drive of the spacing pin 6 of dodge gate.
The power that dead bolt rotates is provided by electromagnet 31, when the control system provides when opening the door instruction, and electromagnet 31 energisings, electromagnetic core 311 shrinks under the effect of magnetic force, and the electromagnetism that drive is connected with electromagnet 31 is separated lock support 32 and is moved.Separate lock support 32 and drive trundle 33 motions, dead bolt rotates under the drive of trundle 33 and unties the restriction to lock dog.When the driven by motor dodge gate that opens the door was opened, the spacing pin 6 of dodge gate drove lock dog 21 and rotates the release completion.Electromagnetism is separated under the effect of lock support 32 at spring force and is resetted after the electromagnet outage, and dead bolt also resets to original state.Lock dog also is in initial open configuration after opening the door.
The extraction principle of door-closing in-place signal of the present invention is: the door-closing in-place signal is provided by left and right sides travel switch 51; When lock dog rotates under the promotion of the spacing pin 6 of dodge gate; Left and right sides block signal contact block 52 is under the drive of left and right sides unlocking signal support 53; Laterally facing to 51 motions of left and right sides travel switch, when lock dog underarm 212 moved to dead bolt lock ditch 221 positions, the front end of left and right sides block signal contact block 52 pushed the plunger 511 of left and right sides travel switch 51; Plunger 511 shrinks and triggers left and right sides travel switch 51 conductings; Notice shield door controller dodge gate is locked, and the signal of locking is provided by the travel switch that is installed in the right and left respectively about this lock, therefore can detect the left and right door lock-out state respectively.
The Principle of Process of manual unlocking of the present invention is: when power-off or off-position, if dodge gate is in locking bit, can adopt the hand-operating unlocking mechanism release to open the door.When manual unlocking pushing block 45 receives the open Door by Hand pressure of device of dodge gate; The elastic force that overcomes manual unlocking spring 44 promotes push rod 43 and in pusher bar support 41, slides; Thereby promote to separate lock support 32 motions to the electromagnetism that lock 1 rear side stretches out, electromagnetism is separated trundle 33 motions on the lock support 32 drive left and right sides dead bolts 22, and then drives dead bolt 22 rotations; When the latch hook on the dead bolt 221 turns to when breaking away from the lock dog underarm, realize release.Push rod 43 compresses the plunger 541 of manual unlocking travel switch 54 in motion process, plunger activated connection signal when unblanking fully.
