Detailed Description
The present invention will be described in detail with reference to the following embodiments and accompanying drawings. In the attached figure 1, K1 is an inductive switch, K2 is an electric push rod, K3 is a microswitch (normally closed door lock switch), K4 is a microswitch (sound and light alarm), SL is sound and light alarm, and K3/K4 micro-motion is all pushed by a trigger block.
Example 1:
as shown in fig. 1 and 2, the non-clamping elevator is provided with an infrared sensing light curtain, an inductive switch for closing the door in place and an anti-clamping trigger device, and the elevator is provided with at least two anti-clamping trigger devices; the anti-pinch trigger device comprises an electric push rod 4 and a trigger device, and the trigger device comprises a microswitch 3 and a trigger block 5 arranged at the front end of the microswitch; a normally closed contact in the microswitch 3 is connected in series to an elevator door lock loop, and a normally open contact in the microswitch 3 is connected in series with an audible and visual alarm; the normally open contact of the inductive switch 2 is connected with the electric push rod 4 in series.
Preferably, the inductive switch 2 is a magnetic induction switch, the magnet in the inductive area 1 is installed on the elevator door system, the magnetic induction switch 2 is installed at the upper end of the elevator door, when the magnetic induction switch 2 moves to the door closing in-place position along with the elevator door, the switch senses the magnet, the normally closed contact on the magnetic induction switch is disconnected, otherwise, the normally closed contact is always switched on when the magnetic induction switch leaves the magnet.
The anti-pinch trigger device is arranged at the edge of one elevator door, and the edge of the other elevator door is provided with a groove matched with the trigger block 5 of the anti-pinch trigger device.
Preferably, the trigger device is arranged on the fixed bracket 6.
Preferably, the electric push rod 4 is arranged on the fixed bracket 6. The electric push rod 4 is arranged behind the trigger device.
Furthermore, a spring 7 is arranged between the trigger block 5 and the microswitch 3. The spring is arranged, so that the safety is higher, and when the device is abnormal, the trigger block cannot hurt people due to the fact that the device is telescopic and can not be formed by the spring.
The elevator door can be provided with a plurality of groups of anti-pinch trigger devices to improve the detection range, when the elevator door is opened, the magnetic induction switch is separated from the magnet in the induction area 1, the electric push rod 4 is electrified to be contracted to drive the fixed support 6 to be contracted, and therefore the trigger block 5 is contracted to the inner side of the door to prevent misoperation. After the lift-cabin door closure finishes, magnetic induction switch senses magnet, electric putter 4 loses the electricity, fixed bolster 6 stretches out, make trigger block 5 stretch out, prevent pressing from both sides trigger device and stretch out automatically and get into the automated inspection state, once have the foreign matter to press from both sides when the door crack, get up after the elevator motion and will drive the foreign matter motion and then touch trigger block 5 and make trigger block 5 move toward the door internal direction, thereby make micro-gap switch 3 move, and the normally closed contact is established ties in the lift lock return circuit in micro-gap switch 3, so micro-gap switch 3 moves lift lock disconnection lift stall, thereby prevent to press from both sides the people, the shearing occurence of failure, and there is the reputation suggestion, and can be connected to the pronunciation suggestion of reporting to stop the anti-pinch trouble.
Example 2:
as shown in fig. 1 and 3, the non-clamping elevator is provided with an infrared sensing light curtain, an inductive switch for closing the door in place and an anti-clamping trigger device, and the elevator is provided with at least two anti-clamping trigger devices; the anti-pinch trigger device comprises an electric push rod 4 and a trigger device, and the trigger device comprises a microswitch 3 and a trigger block 5 arranged at the front end of the microswitch; a normally closed contact in the microswitch 3 is connected in series to an elevator door lock loop, and a normally open contact in the microswitch 3 is connected in series with an audible and visual alarm; the normally open contact of the inductive switch 2 is connected with the electric push rod 4 in series.
Preferably, the inductive switch 2 is arranged at the upper end of the elevator door. The induction area 1 is arranged on the door system, and the induction switch 1 and the induction area 2 form an induction switch for closing the door in place.
