Description
Technical Field
The application relates to an elevator door protection device capable of preventing glass from invading, and belongs to the technical field of elevator accessories.
Background
The elevator is an indispensable tool in modern life, the elevator door linkage device, the safety touch plate and the light curtain mainly ensure the safe use of the elevator, when people or objects are impacted by the door in the process of closing the elevator door, the safety protection device automatically enables the door to be reopened to prevent accidents endangering personal safety, the elevator door machine system is the most frequent part of the whole elevator system, along with the development and progress of society, the use frequency of the elevator is higher and higher, people and objects carried by the elevator are diversified, and particularly, the carried objects are tiny or not shaded, such as transparent glass, tiny 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 plate and the light curtain component are a safety protection device for people and objects to enter an elevator, and the safety protection device is an electromechanical integrated door closing anti-clamping safety device, belongs to an induction type protection device and is used for preventing people or objects from being damaged by clamping in the automatic door closing process of the elevator. The safety touch plate belongs to a soft door on an elevator car door, when the elevator car is in door closing process (light curtain failure or invalidation) and the safety touch plate is in contact with a person and an object, two micro switches between the linked safety touch plates can send a door opening signal to a door machine control system, and the elevator immediately opens the door, so that the effects of not hurting the person and the object are achieved.
The light curtain for elevator is one kind of light type safety protector for elevator door and consists of one safety touch board, two infrared transmitters and receivers on two sides of elevator door, one power box installed on the elevator door and one special flexible cable. The transmitter is internally provided with a plurality of infrared transmitting tubes, and under the control of the MCU, the transmitting and receiving tubes are opened in turn to scan the car door area continuously from top to bottom, so as to form a dense 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 reversely opens until the elevator door can be normally closed after passengers or barriers leave the warning area, so that the aim of safety protection is achieved, and the occurrence of elevator clamping accidents can be avoided. The safety touch plate and the light curtain are different in that: the light beam of the light curtain for generating infrared rays can block the light beam when people or objects enter the elevator, so that the elevator door cannot be closed, and when the safety touch plate is required to contact the people or objects, the micro-switch in the touch plate is triggered, so that the elevator can be opened again. But the safety touch panel and light curtain are undetectable to glass-type transparencies or tiny dog-bone lines, etc.
The majority of currently used elevator door protection devices employ: 1. a safety touch plate is added to the independent mechanical linkage mechanism; 2. a common photoelectric light curtain; 3. a mechanical linkage mechanism safety touch plate adds the light curtain. The three forms of safety protection components have complex mechanical structure, complicated installation and multiple mechanical faults, but no light, electricity, magnetism and other interference, the photoelectric light curtain has high sensitivity, but the structure has high requirements on light resistance, electricity resistance and magnetism resistance, but the light curtain can not protect transparent objects or personnel objects entering an elevator when the light curtain is invalid and damaged, in addition, the light curtain consists of a plurality of groups of infrared transmitting tubes and receiving tubes and is in working condition all the year round, the natural attenuation of the infrared transmitting tubes is easy to cause, and the safety touch plate can not contact and react to tiny objects when in use, so that the elevator door machine system receives door opening signals. Meanwhile, as the touch plate extends out of the car door, the door opening distance of the elevator door is reduced, personnel or objects are easily damaged by impact deformation when entering and exiting the car door, and the service life is influenced to a certain extent.
