Description
Technical Field
The utility model relates to an elevator safety arrangement, in particular to integration elevator light curtain.
Background
The elevator is an indispensable tool in modern life, the elevator door linkage device, the safety touch panel and the light curtain mainly ensure the safe use of the elevator, all accidents which endanger the personal safety are prevented, and the elevator door motor system is the most frequently-acting component in the whole elevator system, and the performance of the elevator door motor system directly influences the performance of the whole elevator.
The elevator door linkage device, the safety touch panel and the light curtain component are a safety protection device for people and objects entering the elevator, are an electromechanical integrated door closing anti-pinch safety device, belong to an inductive protection device and are used for preventing people or objects from being pinched and damaged in the automatic door closing process of the elevator. The safety contact plate belongs to a soft door on an elevator car door, when the elevator car is in the door closing process (light curtain failure or failure), two microswitches between the linked safety contact plates can send a door opening signal to a door machine control system, and the elevator can be opened immediately, so that the effect of not hurting people and objects is achieved.
The elevator light curtain is a light ray type elevator door safety protection device, also belongs to a soft door on an elevator car door, and consists of four parts, namely a safety touch plate, infrared transmitters and receivers on two sides of the elevator car door, a power supply box arranged on the car top and a special flexible cable. The infrared transmitting tubes are arranged in the transmitter, and the transmitting and receiving tubes are opened sequentially under the control of the MCU to continuously scan the car door area from top to bottom to form an intensive infrared protection light curtain. When any beam of light is blocked, the control system immediately outputs a door opening signal, the car door stops closing and rotates reversely to open until the elevator door can be normally closed after the passenger or the blocking object leaves the warning area, so that the safety protection purpose is achieved, and the elevator can be prevented from people and things being jammed. The difference between the safety touch panel and the light curtain is as follows: the light beam generated by the light curtain can block the light beam when a person or an object enters the elevator, so that the elevator door cannot be closed, and the safety touch panel triggers the micro switch in the touch panel to open the elevator door again when the safety touch panel needs to contact the person or the object.
Most of the elevator door protection devices in use today adopt several ways including:
1. the single mechanical linkage mechanism is added with a safety touch plate.
2. A generally photoelectric light curtain.
3. The linkage mechanism safety touch panel of mechanical type adds the light curtain.
The safety protection component of above three kinds of forms, mechanical type's structure is complicated, the installation is loaded down with trivial details, mechanical failure is many, but no interference such as light, electricity, magnetism, photoelectric type's light curtain sensitivity is high, but its structure is to light, electricity-resisting, the requirement of diamagnetism is high, but the light curtain will not protect the personnel object that gets into the elevator when inefficacy damages, in addition because the light curtain comprises a plurality of groups infrared transmitting tube, receiver tube, be in operating condition throughout the year, lead to infrared transmitting tube natural attenuation easily, and the safety touch panel has reduced the door opening distance of lift-cabin door because the touch panel stretches out the sedan-cabin door when using, caused personnel or object easily and passed in and out the sedan-cabin door by the striking deformation damage, have certain influence to life.
