The elevator comprises an upper door frame, a left door frame, a right door frame and an elevator door, wherein the upper door frame is internally provided with a vertical laser transmitter, the floor is internally provided with a vertical laser receiver, the vertical laser transmitter corresponds to the receiver in position, the left door frame is internally provided with a horizontal laser transmitter, the right door frame is internally provided with a horizontal laser receiver, and the horizontal laser transmitter corresponds to the receiver in position. The beneficial effect after adopting above-mentioned technical scheme does: the elevator door detection device has the advantages that large objects can be detected, objects with small sectional areas can be detected, the elevator door can be closed at the moment, the vertical laser beam detects whether foreign matters exist at the door gap, if foreign matters exist, the elevator cannot ascend, the elevator door can be opened until the foreign matters pass through the elevator door detection device, and safety accidents are avoided.

Description

Rope clamping prevention safety device for elevator

Technical Field

The utility model relates to an elevator technical field, concretely relates to lift-cabin door anti-pinch device's improvement.

Background

At present, the elevator is arranged in a large public place or a high-rise residential district, people can conveniently go out, particularly, the floor exceeds more than 6 floors, the elevator is necessary, otherwise, people are inconvenient to go out in daily life, and people can spend a long time going upstairs and downstairs.

Although the problem of preventing passengers from being clamped after the preset time of the elevator is over is solved in China CN207618865U, the elevator door adopts a transverse infrared sensing device to detect foreign matters, but objects with small sectional areas, such as dog ropes, child anti-loss ropes and the like, are difficult to detect, and are easy to fail to detect when the elevator door is closed, so that serious safety accidents are caused, and domestic events of the type occur occasionally, but potential safety hazards are not solved all the time.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to prior art's defect and not enough, provide a rope safety device is prevented pressing from both sides by elevator, it utilizes transversely to add vertical double laser beam detection device and detects, not only can detect human body or large-scale object, but also can detect the less object of sectional area, like the dog rope, children prevent losing hand rope etc. make the lift-cabin door in the twinkling of an eye of closing the door, whether vertical laser beam detects crack department has the foreign matter, if have the foreign matter then the elevator can't rise or descend and open the lift-cabin door, until detecting and passing through, avoid appearing the incident.

In order to achieve the above purpose, the utility model adopts the following technical scheme: it includes vertical laser emitter 1, vertical laser receiver 2, horizontal laser emitter 3, horizontal laser receiver 4, elevator 5, floor 6, elevator 5 includes door frame 51, left door frame 52, right door frame 53, lift-cabin door 54, install vertical laser emitter 1 in the door frame 51, install vertical laser receiver 2 in the floor 6, vertical laser emitter 1 is corresponding with vertical laser receiver 2's position, install the horizontal laser emitter 3 of a plurality of in the left door frame 52, install the horizontal laser receiver 4 of a plurality of in the right door frame 53, horizontal laser emitter 3 is corresponding with horizontal laser receiver 4's position.

The upper door frame 51 is internally provided with a loudspeaker 8. The horn 8 is used to sound an alarm when foreign matter is detected by the transverse and vertical laser beams during the closing of the elevator door 54.

The distance between the transverse laser emitters 3 is 30 cm.

The utility model discloses a theory of operation: when the elevator starts to be closed, the vertical laser transmitter 1 and the transverse laser transmitter 3 simultaneously transmit laser beams, whether foreign matters block the laser beams is detected through the laser beams, if the transverse laser receiver 4 cannot receive the complete laser beams, the foreign matters are in the elevator door, at the moment, the horn 7 gives an alarm sound, and meanwhile, the elevator door is not closed and opened continuously; if the transverse laser receiver receives a complete laser beam and the vertical laser is blocked by foreign matters, so that the vertical laser receiver cannot receive the complete laser beam, the elevator cannot ascend or descend, and meanwhile, the loudspeaker 7 gives an alarm sound and opens the elevator door.

After the technical scheme is adopted, the utility model discloses beneficial effect does: it utilizes transversely to add vertical double laser beam detection device and detects, not only can detect human body or large-scale object, but also can detect the object that the sectional area is less, like dog rope, children prevent losing hand rope etc. makes the lift-cabin door in the twinkling of an eye of closing the door, and vertical laser beam detects the door crack and whether has the foreign matter, if has the foreign matter then the lift can't rise and open the lift-cabin door, until detecting and passing through, avoids appearing the incident.
