Description
Technical Field
The invention relates to an elevator door protection device capable of preventing glass intrusion, and belongs to the technical field of elevator accessories.
Background
The elevator is an indispensable tool in modern life, an elevator door linkage device, a safety touch panel and a light curtain mainly ensure the safe use of the elevator, when people or objects pass through an entrance and are impacted by the door in the closing process of the elevator door, the safety protection device automatically enables the door to be re-opened, all accidents which endanger the personal safety are prevented, an elevator door motor system is a part which acts most frequently in the whole elevator system, along with the development and the progress of the society, the use frequency of the elevator is higher and higher, people and objects carried by the elevator are diversified more and more, particularly, carried objects are thinner and thinner or not shaded, such as transparent glass, thin dog-pulling ropes and the like, and the performance of the elevator directly influences the performance and the use safety 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 effects of not hurting people and objects are 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. However, the safety touch panel and the light curtain cannot detect a transparent object such as a glass type or a thin dog leash.
Most of the currently used elevator door protection devices employ: 1. a single mechanical linkage mechanism is added with a safety touch plate; 2. a common photoelectric light curtain; 3. the linkage mechanism safety touch panel of mechanical type adds the light curtain. The safety protection component of three kinds of forms, mechanical type structure is complicated, the installation is loaded down with trivial details, mechanical failure is many, but interference such as no light, electricity, magnetism, photoelectric type light curtain sensitivity is high, but its structure is to light, anti electricity, anti magnetism requirement height, but the light curtain will not protect the personnel object that gets into the elevator to transparent object or when inefficacy damages, in addition because the light curtain comprises a plurality of groups infrared transmitting tube, receiver tube, is in operating condition throughout the year, leads to infrared transmitting tube natural attenuation easily, and the safety touch panel can't contact reaction to tiny object when using for lift-cabin door machine system receives the signal of opening the door. Meanwhile, the touch plate extends out of the car door, so that the door opening distance of the elevator door is reduced, personnel or objects are easily damaged by impact deformation when entering or exiting the car door, and the service life is influenced to a certain extent.
