Description

Technical Field

[0001] The present application relates to the field of elevator maintenance, and in particular to a method and system for detecting faults in an elevator system. Background Art

[0002] A box elevator, also called a vertical elevator or lift elevator, is an elevator that runs in a vertical shaft. It consists of a closed car and a set of vertically moving guide rails. Box elevators are generally composed of a bridge box, door system, control system, drive system, safety device, guide rail system, etc. The steel cable in the drive device is the main force-bearing structure used to drag the bridge box. In order to improve the safety of elevator use, elevators need to be inspected regularly, and the inspection of the steel cable is to detect whether the surface is damaged and aged, so as to reduce the possibility of the steel cable breaking during use.

[0003] The existing Chinese patent (publication number: CN11270658A) mentions a machine vision-based elevator wire rope detection method. The system converts elevator wire rope samples into digital signals through a high-definition camera based on the characteristics of the wire rope surface, and transmits the image data of the wire rope surface to the image processing module in real time. According to the characteristics of the elevator wire rope surface image, image preprocessing technologies such as image acquisition and grayscale conversion are studied. Through experimental comparison of various filtering algorithms, the best algorithm is selected to reduce the image noise caused by the detection environment, and the wire rope surface correction is realized through interpolation technology. In the judgment of wire rope surface defects, the grayscale co-occurrence matrix parameters are used to extract image texture features, and the neural network is used to distinguish wire rope defects, which has broad market prospects.

[0004] However, in actual use, the structure of the steel wire rope used in elevators is woven from an oil core and multiple strands of steel wire ropes. During use, the steel wire rope is subjected to tension for a long time, which will cause the multiple strands of steel wire ropes to squeeze the oil core wrapped in the middle, causing oil to seep out from the gaps in the steel wire rope. These oils will adhere to the surface of the steel wire rope and come into contact with dust in the air to form oil stains. During visual inspection, the oil stains on the surface of the steel wire rope will directly affect the clarity of the visual imaging and affect the inspection. Summary of the invention

[0005] The purpose of the present application is to solve the problem that the structure of the steel wire rope for elevators proposed in the above-mentioned background technology is formed by weaving an oil core and multiple strands of steel wire ropes.

[0026] The following is combined with Figure 1 —6 Provide further details of this application.

[0027] Embodiments of the present application disclose a method and system for detecting faults in an elevator system.

[0029] When it is necessary to inspect the elevator steel cable, first use the mounting seat 4 to fix the inspection device 1 in the elevator shaft, let the steel cable enter the inspection slot from the side opening of the inspection slot, and then connect the visual sensor 2 on the inspection device 1 to the monitoring system. The inspection personnel inspect the surface of the steel cable passing through the inspection device 1 from the monitoring system to observe whether the surface of the steel cable is damaged or aged. At the same time, the light strip 3 on the inspection device 1 is used to illuminate the passing steel cable so that the cable surface can be clearly uploaded by the visual sensor 2. When the steel cable passes through the inspection device 1, the cleaning mechanism 5 on the inspection device 1 cleans the surface of the steel cable to clean the oil seeping from the inner oil core and the dust attached to it during use, so that the surface of the steel cable is kept clean when passing through the visual sensor 2. At the same time, the cleaning mechanism 5 drives the collecting mechanism 6, and the collecting mechanism 6 scrapes and collects the oil cleaned by the cleaning mechanism 5, so as to reduce the possibility that the oil attached to the cleaning mechanism 5 affects the cleaning of the elevator cable. When the elevator cable passes through the detection device 1 and then the visual sensor 2 performs cable fault detection, the cable passes through the cleaning mechanism 5, so that the cleaning mechanism 5 cleans the oil and dust on the cable. At the same time, the cleaning mechanism 5 drives the collecting mechanism 6, so that the collecting mechanism 6 scrapes and collects the oil cleaned by the cleaning mechanism 5, so that the surface of the cable can be kept clean, and the possibility that the oil and dust attached to the cable surface cannot be observed can be reduced. At the same time, the cleaned oil can be collected, so as to reduce the oil cleaned by the cleaning mechanism 5 from being re-attached to the cable, thereby further improving the effect of cleaning the cable surface.

[0031] When the steel cable passes through the detection groove on the detection device, the cleaning seat 53 between the two support plates 51 approaches the steel cable under the action of the resistance component 54, and then the cleaning brush 52 on the cleaning seat 53 resists the steel cable. When the steel cable moves, the cleaning brush 52 on the cleaning seat 53 cleans the oil stains on the steel cable. By being pushed by the resistance component 54 between the two support plates 51, the cleaning brush 52 on the corresponding cleaning seat 53 resists the steel cable, so that when the steel cable moves, the cleaning brush 52 can clean the oil stains and dust on the surface of the steel cable, thereby reducing the possibility of the steel cable surface being covered with oil stains and dust, which affects the detection.

[0032] Reference Figure 1 and Figure 4 The resistance component 54 includes two supporting telescopic rods 541 arranged between the cleaning plate and the supporting plate 51, one end of the supporting telescopic rod 541 is fixedly connected to the supporting plate 51, and the end of the supporting telescopic rod 541 away from the supporting plate 51 is fixedly connected to the cleaning seat 53, and a resistance spring 542 is sleeved on the supporting telescopic rod 541, and both ends of the resistance spring 542 are fixedly connected to the supporting plate 51 and the cleaning seat 53.

[0033] When the elevator steel cable passes through between the two support plates 51, under the push of the resistance spring 542, the supporting telescopic rod 541 supports the cleaning seat 53 to move closer to the steel cable, so that the cleaning brush 52 on the cleaning seat 53 is in contact with the surface of the steel cable. By utilizing the push of the resistance spring 542, the cleaning brush 52 on the cleaning seat 53 is in contact with the steel cable, so that the cleaning brush 52 can fully contact with the steel cable, which is convenient for adapting to steel cables of different sizes.

[0035] Pushed by the resistance spring 542, the cleaning seat 53 is moved toward the steel cable, and the resistance limiting roller 543 on the cleaning seat 53 is in resistance against the steel cable. The resistance limiting roller 543 provides limiting support for the cleaning seat 53, so that the cleaning brush 52 on the cleaning seat 53 maintains a certain distance when it is in resistance against the steel cable. At the same time, when the steel cable passes through the resistance limiting roller 543, the resistance limiting roller 543 squeezes and disperses the oil, dirt and dust lumps on the surface of the steel cable. By utilizing the resistance limiting roller 543 to resist the steel cable, the cleaning brush 52 maintains a distance from the steel cable, and at the same time, the oil, dirt and dust lumps on the surface of the steel cable are squeezed and dispersed, thereby reducing the possibility of the cleaning brush 52 excessively resisting the steel cable, causing the cleaning brush 52 to wear faster, and at the same time reducing the possibility of oil lumps on the steel cable affecting the cleaning of the cleaning brush 52.

During the lateral movement, the cleaning brush 52 passes through the cleaning scraper, and then the cleaning brush 52 passes through the scraping groove on the cleaning scraper. The scraping groove scrapes the oil on the cleaning brush 52, and the scraped oil enters the collecting box 63. By driving the resistance limiting roller 543 during the movement of the steel cable, the resistance limiting roller 543 drives the collecting brush to move laterally, so that the oil on the cleaning brush 52 is scraped off by the collecting scraper 62, so that when the cleaning brush 52 cleans the steel cable, the possibility of oil adhering to the cleaning brush 52 and affecting cleaning is reduced, and the possibility of oil on the cleaning brush 52 adhering to the steel cable again is reduced.

[0038] Reference Figure 2 and Figure 5 The support assembly 64 includes two support shafts 641 symmetrically arranged on the cleaning seat 53. The two support shafts 641 are rotatably connected to the corresponding support blocks 61. A moving belt 642 is transmission-connected between the two support shafts 641. The moving belt 642 is fixedly connected to a plurality of cleaning brushes 52. The support shafts 641 on the two support blocks 61 support the moving belt 642.

The bevel gear 651 is meshed with the bevel gear 652. The bevel gear 652 passes through the support block 61 and is fixedly connected to the corresponding support shaft 641. When the friction limiting roller 543 is in friction with the steel cable, when the steel cable moves, the steel cable drives the friction limiting roller 543 to rotate, the friction limiting roller 543 drives the bevel gear 1 651 to rotate, the bevel gear 1 651 drives the bevel gear 2 652 to rotate, the bevel gear 2 652 drives one of the support shafts 641 to rotate, the support shaft 641 drives the moving belt 642, and the moving belt 642 drives the cleaning brush 52 to move laterally.
