At the same time, in order to avoid interference of the cleaning device 3 with the normal operation of the optical level sensor 1 in the normal operation state of the elevator, the cleaning device 3 should be arranged in a position to ensure that the optical level sensor 1 is not in contact with the cleaning device 3 when the elevator installation is in the leveling position and in the normal operation state.
In a preferred embodiment of the invention, the self-cleaning device 3 is made of an opaque body.
In a preferred embodiment of the invention, the self-cleaning device 3 is a felt.
In one embodiment of the invention, since the elevator needs to be re-leveled and the like during long-term operation, the photoelectric level sensor will contact the cleaning device 3 even during normal operation of the elevator equipment, and the cleaning device 3 is made of opaque solid in order to avoid affecting the action position of the photoelectric level sensor.
In a preferred embodiment of the present invention, the terminal flat layer is a top flat layer or a bottom flat layer;
the self-cleaning device 3 is arranged at the position of the jump of the top flat layer, and/or
The self-cleaning device 3 is arranged at the jump position of the bottom flat layer.
In one embodiment of the present invention, when the maintenance personnel needs to clean the light level sensor, the maintenance personnel can set the elevator equipment to be in the maintenance mode, and then manually control the elevator equipment to move back and forth between the terminal level and the corresponding skip level. The elevator car is repeatedly operated back and forth, so that the optical lens of the photoelectric sensor is cleaned, and the fault of the photoelectric layer sensor caused by oil stain or dust accumulated on the lens is prevented.
A self-cleaning method of a photoelectric leveling sensor, applied to the self-cleaning device, comprising:
step S1, the elevator equipment is in the terminal leveling layer, and the elevator equipment is in the self-cleaning working condition at present;
in step S2, the elevator apparatus is moved back and forth between the terminal leveling position and the corresponding jump position, so that the photoelectric level sensor 1 is repeatedly brought into contact with the self-cleaning device 3 to perform a cleaning operation.
In the preferred embodiment of the present invention, when the elevator apparatus is in the standby state, as shown in fig. 2, before executing step S1, the method further comprises the following steps:

In a specific embodiment of the invention, a self-cleaning program is preset in a control system of elevator equipment, and each time the elevator equipment is in a standby state, whether the time interval from the current moment of the elevator to the last time for cleaning the photoelectric level sensor exceeds a preset time T is detected, wherein the time value T can be freely set according to the current working environment of the elevator, for example, when the elevator works in a severe environment such as a large dust environment, the value of the preset time T is set to be relatively small so as to accelerate the self-cleaning frequency of the elevator; when the working environment of the elevator is clean, the value of the preset time T is relatively large, the self-cleaning frequency of the elevator is reduced, the friction times of the photoelectric level sensor 1 and the self-cleaning device 3 are reduced, and the abrasion of an optical lens is reduced.
In another embodiment of the invention, two photoelectric floor sensors 1 are provided, which are respectively arranged at the upper and lower ends of the elevator car, and when the elevator equipment detects that the time interval is greater than the preset time T in the standby state, the elevator automatically moves to a terminal floor. And when the terminal floor leveling position is reached, the door closing state is kept. After leveling is finished, the elevator car continuously moves for a certain distance in the terminal direction at a slow speed, so that the optical lens of the photoelectric leveling sensor 1 is contacted with the cleaning device 3 arranged on the light screen 2. The elevator car then moves in the direction of the leveling in the opposite direction and then again in the direction of the terminal. According to the above flow, after the operation is repeated for a predetermined number of times, the operation of the automatic cleaning mode in the end point direction is ended. The elevator then automatically moves to another terminal where the floor is normally level and remains closed. After leveling is finished, the elevator continuously runs for a certain distance in the terminal direction at a slow speed, so that an optical lens of the photoelectric leveling sensor 1 is contacted with a cleaning device 3 arranged on the light screen 2; then the elevator car moves in the direction of leveling in the reverse direction, and after the elevator car repeatedly acts for a preset number of times according to the flow, the operation of the automatic cleaning mode in the terminal point direction is finished. After the two terminal directions are completely operated, the elevator equipment exits from the automatic cleaning working condition and is recovered to the standby state.
In the preferred embodiment of the present invention, when the optical level sensor 1 in the elevator apparatus is in the failure state, as shown in fig. 3, before executing step S1, the method further includes the following steps:
step B1, judging whether the elevator car can run to the terminal leveling in the direction of the photoelectric leveling sensor 1 in the fault state:
if yes, go to step B2;
if not, stopping the operation of the elevator equipment, sending a fault alarm, and then quitting;
step B2, the elevator equipment controls the elevator car to move to the terminal flat floor and keeps the elevator equipment in a door closing state;
step B3, the elevator installation is switched into the self-cleaning mode and then the process goes to step S1.
In the preferred embodiment of the present invention, in step S2, after the elevator apparatus has run back and forth at the terminal leveling floor and the corresponding jump floor position for a predetermined number of times, the procedure proceeds to step B4;
step B4, determining whether the optical level sensor 1 in the fault state has recovered to normal:
if yes, exiting, and recovering the elevator equipment to a normal working state;
if not, the operation of the elevator equipment is stopped, a fault alarm is sent out, and then the elevator equipment is quitted.
In a specific embodiment of the present invention, when the elevator equipment detects that the photoelectric level sensor 1 has a normal blocking fault, it is first determined whether the elevator car can continue to drive to the terminal level corresponding to the faulty photoelectric level sensor 1 by means of the remaining photoelectric level sensors 1. If the elevator can not drive to the terminal leveling by the rest photoelectric leveling sensors 1, the elevator equipment is switched to enter a fault mode to stop running. On the contrary, if the elevator can drive to the terminal leveling floor by depending on the rest photoelectric leveling sensors 1, the elevator judges whether the elevator operates to the terminal or the terminal according to the position of the photoelectric leveling sensor which usually blocks the fault. After the elevator equipment determines the running direction, the elevator car is controlled to drive to the terminal point at the rated speed or at a slow speed and level normally, and meanwhile, the door closing state is kept. After the leveling is finished, the elevator car continuously moves to the jump position in the terminal direction at a low speed, so that an optical lens of the photoelectric leveling sensor 1 contacts a cleaning device 3 arranged on the light screen 2. Then the elevator car reversely runs to the leveling position, all the photoelectric leveling sensors 1 are separated from the cleaning device 3, and according to the flow, after the operation is returned for preset times, whether the photoelectric leveling sensors 1 which are normally shielded and failed originally recover to be normal is judged. If normal has been restored, the elevator installation is restored to the normal operating mode. If the photoelectric level sensor 1 still frequently blocks the fault, the elevator enters a fault mode to stop running.
An elevator installation comprising a self-cleaning device as described above.
The self-cleaning method is adopted for carrying out self-cleaning operation on the photoelectric leveling sensor arranged in the elevator equipment.
