[0047] The safety gear cleaning system provided by this application, the schematic diagram of its application environment is as Figure 1 shown, including: a safety gear 10, an elevator main control system 20, a safety control board 30 and a limit switch 40 which are connected to each other, and a motor 50 connected to the elevator main control system 20; the safety gear 10 is provided with an electromagnet 11, an armature 12, a wedge block 13, an elastic member 14 and a linkage rod 15; the linkage rod 15 includes at least three ends, and the armature 12, the wedge block 13 and the elastic member 14 are respectively connected to the three ends of the linkage rod 15 in correspondence; the electromagnet 11 is connected to the safety control board 30 and the motor 50.

[0048] Among them, the safety gear refers to an electric safety gear provided with an electromagnet, an armature, an elastic member, a wedge block and a linkage rod; the safety gear can be arranged on the car, and the safety gear can also be provided with a housing, and then the armature, the electromagnet, the spring and the linkage rod are arranged inside the housing.

[0049] Among them, the electromagnet, the armature, the elastic member, the wedge block and the linkage rod can be implemented by using any existing technology, for example, the elastic member can be a spring. The elevator main control system can also be implemented by using any existing technology, for example, the elevator main control system can be implemented by a computer, a smart terminal or a processor. The safety control board can also be implemented by using any existing technology.

[0050] Among them, one end of the elastic member is in driving connection with one end of the linkage rod, and the other end of the elastic member can be fixedly connected to the housing of the safety gear, and the other end of the elastic member can also be fixedly connected to the outside (such as a wall).

[0051] Among them, the linkage rod is obtained by combining at least two rods, and the junction of the two rods can be rotatably connected to the housing of the safety gear, and the junction of the two rods can also be rotatably connected to the outside (such as a wall), so that when one end of the linkage rod moves, it can drive the other two ends of the linkage rod to move.

[0052] The elevator main control system is used to send a cleaning instruction to the safety control board, so that the safety control board controls the electromagnet of the safety gear to lose power according to the received cleaning instruction.

[0053] Among them, the cleaning instruction refers to an instruction used to instruct the safety control board to control the electromagnet to lose power, so as to drive the wedge block to clean its moving path through the linkage rod.

[0054] Specifically, there is a communication connection (such as wired communication or wireless communication) between the elevator main control system and the safety control board. The elevator main control system can set a timing thread. When the current time reaches the preset time, it sends a cleaning instruction to the safety control board. The safety control board receives the cleaning instruction. Since there is an electrical connection between the safety control board and the armature, the safety control board can then, according to the indication of the cleaning instruction, cut off the power supply of the electromagnet of the safety clamp through the control circuit.

[0055] For example, the cleaning instruction can instruct the safety control board to immediately stop supplying power to the electromagnet, so that the wedge block immediately starts the cleaning action; for another example, the cleaning instruction can also instruct the safety control board to stop supplying power to the electromagnet after 10s, so that the wedge block starts the cleaning action after 10s.

[0056] The elastic component is used to expand when the power between the safety control board and the electromagnet is lost, so that the elastic component drives the armature to move from the target position to the limit switch through the linkage rod, and so that the elastic component drives the wedge block to clean the moving path of the wedge block through the linkage rod.

[0057] Among them, the limit switch is arranged on the moving path of the armature along the direction away from the electromagnet.

[0058] Specifically, Figure 2 is a schematic diagram of the principle of the safety clamp cleaning method. As Figure 2 shown, when the electromagnet is powered on, the armature is magnetically attracted to the electromagnet. At this time, the position of the armature after magnetic attraction can be regarded as the target position. After the electromagnet is powered off, it will demagnetize, and the elastic component expands and resets along the axial direction. Since one end of the elastic component is connected to one end of the linkage rod (marked as end A), when the elastic component expands along the axial direction, it will drive the end A of the linkage rod to move along the axial direction together; make the end of the armature connected to the linkage rod (marked as end B) move along the direction away from the electromagnet, and then drive the armature to start moving along the direction away from the electromagnet from the target position, that is, the armature moves from the target position to the limit switch; at the same time, make the end of the wedge block connected to the linkage rod (marked as end C) move upward in the vertical direction, driving the wedge block connected to the end C of the linkage rod to also move upward in the vertical direction, and the wedge block cleans the moving path during the upward movement.

[0059] It should be noted that the wedge block can also be connected to the linkage rod through the lifting rod 16. Among them, the lifting rod can be made of metal material (such as an iron rod), or can be made of fiber material, and of course can also be made of a composite material. Therefore, when the end C of the linkage rod moves upward, the wedge block is lifted through the lifting rod, so that the wedge block moves upward and cleans the moving path.

[0060] A limit switch for sending a signal indicating the arrival of the armature to the elevator main control system.

[0061] The elevator main control system is also configured to send a reset command to the motor upon receiving the arrival signal.

[0062] A motor for controlling the movement of the electromagnet towards the armature according to the reset command and pulling the armature to the target position.

[0063] Wherein, the limit switch is a component that realizes circuit control by the collision of the moving parts of the production machinery to make its contacts act. The limit switch is used to limit the travel of the armature movement; the limit switch can be implemented by any existing technology. The motor can also be implemented by any existing technology, such as a drive motor.

[0064] Wherein, the arrival signal is information describing that the armature has reached the limit switch.

[0065] Specifically, when the armature moves to the limit switch and collides with the limit switch, it can be confirmed that there is no obstruction in the moving path of the armature or the wedge block to jam the movement of the armature or the wedge block. Then the limit switch generates an arrival signal of the armature and sends the arrival signal to the elevator main control system. The elevator main control system receives the arrival signal, generates a reset command and sends it to the motor, and generates a power-on command and sends it to the safety control board. The safety control board controls the electromagnet to be powered on. The motor drives the electromagnet to move towards the armature according to the received reset command. When the distance between the electromagnet and the armature is small enough, the electromagnet and the armature are magnetically attracted, and then the motor drives the electromagnet to return to pull the armature to the target position, realizing the reset of the armature.

[0066] Furthermore, Figure 3 is a schematic diagram of the motor receiving the reset command in another embodiment, as Figure 3 shown. The elevator main control system can also be connected to a motor control unit 60. The motor control unit is connected to the motor. The elevator main control system generates a reset command and sends it to the motor control unit, and then forwards the reset command to the motor through the motor control unit, so that the motor controls the electromagnet to move towards the armature according to the received reset command and pulls the armature to the target position.

[0067] It should be noted that during the cleaning process of the safety clamp, the elevator main control system will send a stop work command to the elevator, so that the elevator stops serving according to the stop work command. After confirming the reset of the armature, the elevator main control system will send a restart work command to the elevator, so that the elevator resumes service.

[0068] The above-mentioned safety gear cleaning system sends a cleaning instruction to the safety control board through the elevator main control system, so that the safety control board controls the electromagnet of the safety gear to lose power according to the received cleaning instruction; when power is lost between the safety control board and the electromagnet, the elastic component expands, so that the elastic component drives the armature to move from the target position to the limit switch through the linkage rod, and the elastic component drives the wedge block to clean the moving path of the wedge block through the linkage rod; the arrival signal of the armature is sent to the elevator main control system through the limit switch; when the arrival signal is received, the elevator main control system sends a reset instruction to the motor; furthermore, the motor controls the electromagnet to move towards the armature according to the reset instruction and pulls the armature to the target position, which not only realizes the cleaning of the moving path of the wedge block, avoids the accumulation of sludge and sand on the wedge block, improves the reliability of the safety gear, but also can reset the armature through the motor to facilitate the next cleaning of the wedge block, thereby improving the cleaning efficiency of the safety gear.

[0069] In one embodiment, the wedge block is used to move upward when power is lost between the safety control board and the electromagnet and clean the upward moving path; the elastic component is also used to contract when the armature is pulled to the target position, so that the elastic component drives the wedge block to move downward through the linkage rod.

[0070] Specifically, when power is lost between the safety control board and the electromagnet, the elastic component expands along the axial direction, so that one end of the wedge block connected to the linkage rod (marked as end C) moves upward in the vertical direction, driving the wedge block connected to the end C of the linkage rod to also move upward in the vertical direction. Furthermore, the end C of the linkage rod (or the lifting rod connecting the end C of the linkage rod and the wedge block) lifts the wedge block upward, triggering the action of the wedge block, so that the wedge block cleans the upward moving path.

[0071] Furthermore, as Figure 3 shown, the motor pulls the armature to the target position through the electromagnet. Since the armature is connected to one end of the linkage rod (marked as end B), when the armature moves towards the target position, it will drive the end B of the linkage rod to move towards the target position together; furthermore, one end of the linkage rod connected to the elastic component (marked as end A) moves along the axial direction, driving the elastic component connected to the end A of the linkage rod to also contract along the axial direction; at the same time, one end of the linkage rod connected to the wedge block (marked as end C) moves downward in the vertical direction, driving the wedge block connected to the end C of the linkage rod to also move downward in the vertical direction.

[0072] It should be noted that, to ensure the cleaning effect of the safety clamp, the moving distances of the armature and the wedge block should not be set too short. When the armature moves to the limit switch, the distance between the armature and the electromagnet is relatively far. Even if the electromagnet is powered on currently, the magnetic force of the electromagnet is not sufficient to attract the armature to move in the direction close to the electromagnet. Therefore, it is necessary to drive the electromagnet to move actively towards the armature through the motor, so that the armature and the electromagnet are magnetically attracted to facilitate the traction of the armature back to the target position for resetting.

[0073] In this embodiment, when the power of the safety control board and the electromagnet is lost, the wedge block moves upward, and the upward moving path is cleaned; when the elastic component contracts when the armature is pulled to the target position, the elastic component drives the wedge block to move downward through the linkage rod, which not only realizes the cleaning of the upward moving path of the wedge block and improves the reliability of the safety clamp, but also realizes the reset of each component (such as the wedge block, the elastic component and the armature) in the safety clamp, so as to facilitate the next cleaning of the safety clamp, thereby improving the cleaning efficiency of the safety clamp.

[0074] In one embodiment, the above safety clamp cleaning system further includes a car 70; the wedge block contacts the car; the wedge block is further used to perform vibration cleaning on the moving path in contact with the car.

[0075] Among them, the limit switch can be set above the car.

[0076] Among them, the installation, operation and connection of the car can be realized by any existing technology that meets the requirements, and will not be elaborated here.

[0077] Specifically, there is contact between the wedge block and the car. For example, when the wedge block moves upward, it can clamp the guide rail of the car. A vibration device can also be set on the wedge block; the vibration device detects the wedge block, and when the vibration device detects that the wedge block moves upward, the vibration device vibrates, thereby driving the wedge block to perform vibration cleaning on the upward moving path in contact with the car.

[0078] In this embodiment, by performing vibration cleaning on the moving path in contact with the car through the wedge block, the pollutants such as sludge and sand on the upward moving path of the wedge block can be vibrated off, so as to achieve the effect of cleaning the moving path, without manual cleaning of the safety clamp, and the cleaning efficiency of the safety clamp is improved.

[0079] In one embodiment, the limit switch is further used to send the jamming signal of the armature to the elevator main control system if it detects that the armature does not reach the limit switch.

[0080] Among them, the jamming signal refers to the information describing that the armature does not reach the limit switch.

[0081] Specifically, after the elevator main control system sends a cleaning instruction, it starts timing. When the timing reaches a preset first duration, it sends a confirmation instruction to the limit switch. The limit switch receives the confirmation instruction and waits for a preset second duration according to the confirmation instruction. If the limit switch still does not collide with the armature after waiting for the preset second duration, it can be confirmed that there is an obstacle blocking the movement path of the armature or the wedge block, which restricts the movement of the armature or the wedge block. Then, a jamming signal of the armature is generated and sent to the elevator main control system. The elevator main control system sends a stop work instruction to the elevator, so that the elevator stops serving according to the stop work instruction.

[0082] Among them, the first duration refers to the time limit for the elevator main control system to wait for the limit switch to feedback the arrival signal. The second duration refers to the time limit for the limit switch to wait for the armature after receiving the confirmation instruction.

[0083] In this embodiment, if it is detected that the armature does not reach the limit switch, the limit switch sends the jamming signal of the armature to the elevator main control system, so that the elevator main control system can timely learn about the jamming situation of the safety clamp, which is convenient for the staff to arrange in-depth maintenance work of the safety clamp, avoid elevator accidents caused by the failure of the safety clamp, and improve the reliability of the safety clamp.

[0084] In one embodiment, the limit switch is further configured to send the arrival signal or the jamming signal of the armature to the safety control board; the safety control board is further configured to forward the arrival signal or the jamming signal to the elevator main control system.

[0085] Specifically, in one implementation, as Figure 1 shown, the limit switch is connected to the elevator main control system, and then the limit switch directly sends the arrival signal or the jamming signal of the armature to the elevator main control system. In another implementation, Figure 4 is a schematic diagram of the connection structure of the limit switch. As Figure 4 shown, the limit switch can also be connected to the safety control board, and the safety control board is connected to the elevator main control system. Then, the limit switch sends the arrival signal or the jamming signal of the armature to the safety control board, and the safety control board forwards the arrival signal or the jamming signal to the elevator main control system.

[0086] In this embodiment, the arrival signal or the jamming signal of the armature is sent to the safety control board through the limit switch; the arrival signal or the jamming signal is forwarded to the elevator main control system through the safety control board, realizing another transmission mode of the arrival signal and the jamming signal, which can be applied to different application scenarios.

[0087] The safety clamp cleaning method provided by the embodiments of the present application can be applied to such as Figure 1In the application environment shown, the elevator main control system sends a cleaning instruction to the safety control board, so that the safety control board controls the electromagnet in the safety clamp to lose power according to the received cleaning instruction, and the elastic component in the safety clamp relaxes, so that the elastic component drives the armature in the safety clamp to move from the target position to the limit switch through the linkage rod in the safety clamp, and so that the elastic component drives the wedge block in the safety clamp to clean the moving path of the wedge block through the linkage rod; in the case of receiving the arrival signal of the armature fed back by the limit switch, a reset instruction is sent to the motor, so that the motor controls the electromagnet to move towards the armature according to the reset instruction and pulls the armature to the target position. Among them, the elevator main control system can be implemented by any existing technology, such as a computer, a smart terminal or a processor.

[0088] In one embodiment, as Figure 5 shown, a safety clamp cleaning method is provided. Taking the elevator main control system in Figure 1 as an example for illustration, it includes the following steps:

[0089] Step S501: Send a cleaning instruction to the safety control board, so that the safety control board controls the electromagnet in the safety clamp to lose power according to the received cleaning instruction, and the elastic component in the safety clamp relaxes, so that the elastic component drives the armature in the safety clamp to move from the target position to the limit switch through the linkage rod in the safety clamp, and so that the elastic component drives the wedge block in the safety clamp to clean the moving path of the wedge block through the linkage rod.

[0090] Step S502: In the case of receiving the arrival signal of the armature fed back by the limit switch, send a reset instruction to the motor, so that the motor controls the electromagnet to move towards the armature according to the reset instruction and pulls the armature to the target position.

[0091] It should be noted that since the processing processes of components such as the elevator main control system, the safety control board and the safety clamp have been described in detail in the above embodiments, they will not be elaborated here.

[0092] In the above safety gear cleaning method, the elevator main control system sends a cleaning instruction to the safety control board. According to the received cleaning instruction, the safety control board controls the electromagnet in the safety gear to lose power, and the elastic component in the safety gear relaxes, so that the elastic component drives the armature in the safety gear to move from the target position to the limit switch through the linkage rod in the safety gear, and the elastic component drives the wedge block in the safety gear to clean the moving path of the wedge block through the linkage rod; when receiving the arrival signal of the armature feedback by the limit switch, a reset instruction is sent to the motor, and the motor controls the electromagnet to move towards the armature according to the reset instruction and pulls the armature to the target position. By adopting this method, not only the cleaning of the moving path of the wedge block is realized, the accumulation of sludge and sand on the wedge block is avoided, and the reliability of the safety gear is improved, but also the armature can be reset by the motor to facilitate the next cleaning of the wedge block, thus improving the cleaning efficiency of the safety gear.

[0093] To more clearly illustrate the safety gear cleaning method provided by the embodiments of the present disclosure, the above safety gear cleaning method will be specifically described below with a specific embodiment. Another safety gear cleaning method is provided, which specifically includes the following: when the elevator is equipped with a safety gear, the electromagnet of the safety gear is powered off regularly (for example, once a day) through the safety control board, the spring of the safety gear relaxes and resets, and the armature of the safety gear moves from the target position to the limit switch. Since the armature is linked with the wedge block of the safety gear through the linkage rod, the wedge block is lifted upward at the same time. The limit switch is used to detect whether the armature moves to the specified position to confirm whether the wedge block is stuck. If the wedge block is not stuck, the limit switch sends an arrival signal to the elevator main control system; when receiving the arrival signal, the elevator main control system sends a reset instruction to the motor; then the motor drives the electromagnet to move towards the armature and pulls the armature back to the target position, and the elevator resumes normal service. If the wedge block is stuck, the elevator main control system reports the corresponding fault information and stops the elevator service.

[0094] In this embodiment, the following beneficial effects can be achieved: by regularly and automatically triggering the lifting of the safety gear wedge block, the automatic cleaning of the moving path of the wedge block can be realized, the accumulation of sludge and sand can be avoided, and the reliability of the electric safety gear can be improved.
