Door lock system for rail transit emergency door of the present invention is installed in the escape door both sides respectively, the structure on two sides symmetry, and the locking and unlocking principle is identical, and existing accompanying drawings is following:
The locking process of opening the door of the present invention is to use the switch door that is installed on the dodge gate synchronously with the power of 4 transmissions; When opening the door, be with 4 to drive 13 motions of idle stroke slide block synchronously; Idle stroke slide block 13 drives 14 motions of release rolling wheel support, and release rolling wheel support 14 drives release roller 15 and on the inclined-plane of the overhead gage 181 of lock frame 18, rolls, and drives lock frame 18 and slide block 17 fixed thereon and moves upward along slide 16; When the rising distance of the lower baffle plate 182 of locking frame 18 surpasses the axle center of locking roller 22; Between the lower baffle plate 182 of lock frame 18 and locking roller 22, form to change distance, be with 4 to continue transverse movements synchronously, lock the height that frame 18 continues to be raised to its lower baffle plate 182 and be higher than the height that locks roller 22; This moment, the transverse movement restriction of movable door lock frame 18 was disengaged, and dodge gate is opened the release success.Here; The idle stroke horizontal cross motion of idle stroke slide block 13 is keys of release; The horizontal cross motion of idle stroke slide block 13 drives release roller 15 in the motion of lock frame 18 ramps; Promote the thrust that lock frame 18 overcomes back-moving spring 19 and move upward, thus the restriction that lock frame 18 is broken away from be installed in the locking roller 22 on the fixed gate and release.At closing time, be with 4 to drive release roller 15 to left movement and move to left synchronously, lock frame 18 resets under the thrust of back-moving spring 19; When moving to locking roller 22 and contact with the lower baffle plate of locking frame 18; Because of the limit of closing the door of lock frame 18 lower baffle plates is a hypotenuse, locking roller 22 promotes the 18 upwards liftings of lock framves, when door-closing in-place; Locking roller 22 surpasses the lower baffle plate of lock frame 18, and lock frame 18 loses the upwards lifting power of locking roller 22 and under the effect of back-moving spring 19, resets.Lock roller 22 this moment and just keep off in the perpendicular side plate side of lock frame 18 lower baffle plates, thus door lock is dead.Dodge gate can not be opened under external force.
When the chance state of emergency needs manual unlocking; Upwards spur manual unlocking pull bar 36; Drive dovetail slide block 33 overcomes manual unlocking back-moving spring 35 in dovetail slide 34 resistance moves upward, and moves upward through connecting rod 32 and manual unlocking stand 31 drive lock framves 18, thereby realizes release.
Choosing of this lock locking signal be, after door locked, latch-down baffle 5 just in time block be installed on the gear wheel frame near switch and in the travel switch number of winning the confidence scope, get this lock of reporting system locking behind the signal near switch.After opening the door, latch-down baffle 5 breaks away near the inductive switching distance, feeds back to this lock of notifications near switching signal and unties.
Choosing of this lock manual unlocking signal is to choose through manual unlocking baffle plate 6; When the manual unlocking pull-up; Manual unlocking baffle plate 6 gets near the inductive switching scope, sends signal near switch, and system is received from manual unlocking will take corresponding processing near switching signal.
