Description

TECHNICAL FIELD

[0002] As an indispensable vertical transportation tool in modern buildings, the safety and reliability of the elevator are directly related to the safety of people's life and property. As the core component of the elevator traction system, the traction sheave realizes the lifting movement of the elevator car through the friction between the limiting groove on its surface and the drive wire.

[0003] The Chinese patent with publication number CN223002536U discloses an elevator traction sheave oil stain removal device, which comprises a carbon fiber brush composed of a carbon fiber bundle and a brush holder. A sliding block is fixed at the bottom of the brush holder, and the sliding block is arranged in a sliding table through a guide shaft and a lead screw. The sliding table includes a sliding table support frame and a sliding table bottom plate, and the guide shaft and the lead screw are fixed at both ends of the sliding table support frame. The sliding table is arranged on a carbon fiber bottom plate, and the lead screw penetrates through the sliding table support frame and is connected with a stepping motor through a traction mechanism. The stepping motor is arranged on the carbon fiber bottom plate near the end of the sliding table. A first limit switch and a second limit switch are arranged on the carbon fiber bottom plate, and a milling machine workpiece positioner is arranged at the bottom of the carbon fiber bottom plate. A heavy-duty magnetic table base is arranged at the lower end of the milling machine workpiece positioner, and a control box is arranged on the side of the heavy-duty magnetic table base. A controller is arranged in the control box. The utility model can reduce the work burden and avoid the operation risk of manual cleaning of elevator traction sheave oil stains.

[0004] According to the above-mentioned prior art, it is found that the traditional oil sludge cleaning method highly depends on manual regular operation, which not only needs to stop the elevator to affect normal use, but also requires maintenance personnel to perform high-altitude operation, which has significant safety hazards. More importantly, this passive maintenance cannot realize real-time monitoring and lacks preventive maintenance capability, and often can only intervene after the problem occurs. In addition, the continuous accumulation of oil sludge in the limiting groove of the traction sheave will directly cause the friction between the drive wire and the wheel groove to decrease, which may cause the steel wire rope to slip, the traction force to be insufficient, and other operation failures. At the same time, the hard particles in the oil sludge will accelerate the wear of the steel wire rope and the traction sheave, which seriously affects the safety of elevator operation and the service life of the equipment.

[0024] The number of the cleaning rods 208, the sliding tubes 209, the telescopic rods 210 and the electronic springs 211 is set to be multiple, and every two cleaning rods 208, the sliding tubes 209, the telescopic rods 210 and the electronic springs 211 are symmetrically arranged on the surface of the cleaning plate 207, and every electronic spring 211 is located in the region between two symmetrically arranged cleaning rods 208, when the electronic spring 211 is in the contraction state, it can drive two symmetrically arranged telescopic rods 210 to move along the direction of the middle part of the sliding tube 209, two cleaning rods 208 close to each other at one end of the cleaning rod 208, two cleaning rods 208 deflect along the inside of the cleaning plate 207, and the included angle formed by two cleaning rods 208 away from the cleaning plate 207 gradually increases.

[0026] The detection unit 3 includes a power supply seat 301 and an infrared detection device 302, the power supply seat 301 is located above the cleaning plate 207, and the infrared detection device 302 can detect the sludge accumulation state of the inner wall of the traction wheel 104 in real time, the top of the power supply seat 301 and the bottom of the infrared detection device 302 are electrically connected with each other, and the power supply seat 301 is used for supplying power to the infrared detection device 302.

[0027] In use, first, the whole device is fixed beside the elevator traction system through the mounting mechanism 1. Specifically, the mounting plate 101 is firmly installed on the traction frame or the appropriate position nearby by cooperating the positioning hole on the connecting rib 102 on both sides of the mounting plate 101 with the pin, ensuring the stability of the whole device. At this time, the traction wheel normally rotates on the rotating shaft 103, and a plurality of limiting grooves 106 on the surface of the traction wheel respectively embed the transmission steel wires 105.

[0028] After the device starts to work, the detection unit 3 is started first. The power supply seat 301 located above the cleaning plate 207 continuously supplies power to the infrared detection device 302, so that it can continuously scan the inner wall of the rotating traction wheel (i.e. the region of the limiting groove 106 in contact with the transmission steel wire 105) and monitor the attachment and accumulation thickness of the oil sludge in real time.

[0029] When the infrared detection device 302 monitors that the thickness of the sludge in one or more of the limiting grooves 106 exceeds the preset safety or cleaning threshold, the cleaning mechanism 2 automatically starts the cleaning program. The adjusting plate one 205 and the adjusting plate two 202 on both sides of the mounting plate 101 are driven by the linear drive device 206 (such as an electric push rod) to drive the cleaning plate 207 and the cleaning plate 207 two below to move synchronously towards the middle traction wheel until the cleaning rod 208 assembly on the cleaning plate 207 approaches the surface of the traction wheel.

[0030] Next, for the specific limiting groove 106 that needs to be cleaned, the corresponding cleaning rod 208 assembly starts to act. Each pair of symmetrically arranged cleaning rods 208 is linked and controlled by an electronic spring 211. After receiving the cleaning instruction, the electronic spring 211 is energized and switched to the retracted state. This action pulls the two telescopic rods 210 to slide towards the middle along the sliding tube 209 outside. Since the ends of the telescopic rods 210 are hinged to one end of the cleaning rod 208, the inward movement of the telescopic rods 210 will cause the two cleaning rods 208 to approach each other at the end of the cleaning plate 207, causing the cleaning rod 208 to deflect around the fulcrum on the cleaning plate 207. As a result, the end of the two cleaning rods 208 away from the cleaning plate 207 (i.e. the end with the clamping block 212 and the arc-shaped baffle 213) will open like a pair of pincers, increasing the included angle formed thereby, so that it can accurately straddle both sides of the corresponding transmission wire 105. At this time, the arc-shaped clamping block 212 at the end of the cleaning rod 208 will gently adhere to the transmission wire 105, serving as a preliminary positioning and guiding function, ensuring that the cleaning rod 208 is aligned with the limiting groove 106.

[0031] After the clamping block 212 is positioned, the electronic spring 211 is switched to the extended state, pushing the two telescopic rods 210 to move towards both ends along the sliding tube 209. This causes the end of the two cleaning rods 208 close to the cleaning plate 207 to move away from each other, and the far end to move together, reducing the included angle. In the process, the cleaning rod 208 is embedded in the limiting groove 106 of the traction wheel. As the traction wheel continues to rotate, the cleaning rod 208 embedded in the groove uses the contact between its side and the groove wall to scrape off the sludge attached to the groove wall.

[0032] The scraped sludge moves along the specially designed sludge groove (its width matches the limiting groove 106) on the surface of the cleaning rod 208, collects and is temporarily stored in the temporary storage bin 203 at the bottom of the cleaning rod 208 to avoid splashing or secondary pollution. The arc-shaped baffle 213 at the end of the cleaning rod 208 plays a shielding and guiding role during the cleaning process, preventing the sludge from being thrown out and ensuring that it is guided into the sludge groove. The entire cleaning process is dynamic, and as the traction wheel rotates, the cleaning rod 208 continuously scrapes the entire circumference of the limiting groove 106.

[0033] When the infrared detection device 302 confirms that the area of the sludge has been cleaned to the standard thickness, the cleaning instruction is released. The electronic spring 211 is activated again, causing the cleaning rod 208 to exit the limiting groove 106, expand, and disengage from the contact with the transmission wire 105. Subsequently, the linear drive device 206 is activated, driving the cleaning plate 207 and the cleaning rod 208 and all components back to the initial safe position away from the traction sheave, waiting for the next detection and cleaning instruction. Through real-time monitoring by the detection unit 3 and automatic precise cooperation of the cleaning mechanism 2, online detection and automatic cleaning of the elevator traction sheave sludge are realized.

[0034] Secondly, when the elevator is in normal operation and the cleaning instruction is not triggered, the device is in a normal monitoring and supporting state. At this time, the cleaning plate 207 in the upper top rod 201 and the multiple cleaning rods 208 are controlled by the electronic spring 211, causing the clamping blocks 212 at the ends to gently adhere to the outer surface of the transmission wire 105 with a small clamping force, mainly playing three roles: first, providing slight support to balance the pressure between the wire and the traction sheave groove, reducing wear and tear; second, when the wire is slightly misaligned, the clamping force can be adjusted to guide the wire back to its original position. At the same time, the cleaning rods 208 of the lower top rod 204 component remain in an open state, with their cleaning parts hanging below the traction sheave limiting groove 106 to avoid unnecessary wear and tear caused by contact. Secondly, the multiple cleaning rods 208 in the lower top rod 204 are in contact with the outer surface of the transmission wire 105 through the clamping blocks 212 at the end away from the cleaning plate 207, and assist the multiple cleaning rods 208 in the upper top rod 201 to simultaneously relieve the tension between the transmission wire 105 and the traction sheave 104. Throughout the process, the infrared detection device 302 continuously scans the inner wall of the wheel groove to monitor the thickness of the sludge.

[0035] When the system detects extreme situations such as out-of-control operation (e.g., overspeed descent) of the elevator, the device immediately triggers an emergency safety mode.

[0036] The upper top rod 201 and the lower top rod 204 assembly cooperate to brake, and two sets of cleaning mechanisms 2 are driven by the linear driving device 206 to quickly approach the steel wire and the traction wheel. The lower top rod 204 assembly, the electronic spring 211 of all the cleaning rods 208 instantaneously acts, so that the included angle of each pair of cleaning rods 208 is sharply increased to the maximum. At this time, the clamping blocks 212 at the ends of the cleaning rods 208 strongly clamp the transmission steel wire 105 with a large wrap angle, and a large friction force is generated. The upper top rod 201, the cleaning plate 207 and the plurality of cleaning rods 208 are opposite to the cleaning plate 207 and the plurality of cleaning rods 208 in the lower top rod 204, and the electronic spring 211 of all the cleaning rods 208 drives each pair of cleaning rods 208 to sharply decrease the included angle, so that the clamping blocks 212 tightly hold the outside of the transmission steel wire 105 in a “pinching” manner, and a large friction force is also generated, so that the elevator car is slowly descended, and the upper top rod 201, the cleaning plate 207 and the plurality of cleaning rods 208 and the lower top rod 204, the cleaning plate 207 and the plurality of cleaning rods 208 simultaneously apply bidirectional increasing friction force to the plurality of transmission steel wires 105 from different angles, forming a gradual and controllable braking force, forcing the traction wheel to slow down, and finally realizing the safe slow descent of the elevator car until stopping.

[0037] The application also provides a use method of the elevator traction sheave oil sludge on-line detection and automatic cleaning device, comprising the following steps: S1, first, device installation and initial monitoring: the device is stably fixed beside the elevator traction system through the connecting ribs 102 and the positioning holes of the mounting plate 101 and the positioning holes cooperate with the pins, so that the mounting plate 101 and the traction wheel on the rotating shaft 103 are in the normal working position; the detection unit 3 is started, and the power supply seat 301 continuously supplies power to the infrared detection equipment 302, so that the infrared detection equipment 302 performs real-time scanning on the inner wall of the limiting groove 106 of the rotating traction wheel, and monitors the thickness of the oil sludge accumulation; S2, then when the oil sludge exceeds the standard, the linear driving device 206 pushes the cleaning plate 207 to make the cleaning rod 208 embedded in the limiting groove 106, and the oil sludge is automatically scraped off in the process of rotating the traction wheel; S3, finally, the cleaning is completed and the safety braking function is realized: the cleaning rod 208 is reset and withdrawn after the cleaning reaches the standard, and the device returns to the monitoring state; if the elevator is out of control, the safety mode is triggered immediately, the upper and lower cleaning mechanisms 2 are synchronously actuated, the electronic spring 211 drives the cleaning rod 208 to apply bidirectional friction force to the transmission steel wire 105 in different clamping modes, and gradual safety slow descent is realized.
