Description

Technical Field

[0001] This invention belongs to the field of elevator wire rope testing technology, specifically, it relates to an automated testing device and method for elevator wire rope wear. Background Technology

[0002] As a core load-bearing component of elevator operation, the wear and tear of elevator wire ropes directly affects elevator safety. Therefore, regular and accurate inspection of elevator wire ropes is a crucial step in ensuring safe elevator maintenance. With the development of automated inspection technology, various elevator wire rope wear testing equipment has gradually replaced manual inspection, significantly improving inspection efficiency and accuracy.

[0003] Existing automated elevator wire rope testing equipment generally relies on an external power source to drive core actions such as probe switching, transmission linkage, and contaminant cleaning. However, the elevator shaft environment is harsh, with problems such as small space, poor ventilation, a lot of oil and dust, and large humidity fluctuations that easily cause condensation. This can cause the external power source to fail due to pollution and corrosion, leading to abnormal linkage of the testing agency, interruption of testing and missed detection, or even equipment shutdown affecting elevator operation. The defects are significant.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows: An automated inspection device for the wear of elevator wire ropes includes an elevator wire rope detector, which is equipped with a visual inspection probe and has a built-in visual sensor. The visual inspection probe corresponds to the wire rope to be tested.

[0006] The elevator wire rope tester is equipped with a centrifugal wheel, which is in close contact with the wire rope to be tested. During normal elevator operation, the lifting and lowering of the wire rope to be tested drives the centrifugal wheel to rotate synchronously. A pair of counterweights are slidably installed on the end face of the centrifugal wheel. A baffle is also slidably installed on the elevator wire rope tester. The baffle is used to block the visual inspection probe during non-testing time to prevent oil and dust from affecting the visual inspection probe. A synchronization component is connected between the counterweights and the baffle. The synchronization component is used to drive the baffle to separate from the visual inspection probe during the rotation of the centrifugal wheel and facilitate the test. Inside the housing of the elevator wire rope tester, a scraper is rotatably installed, and the scraper is synchronously connected to a synchronization component. The synchronization component is used to drive the scraper to fit against the side wall of the centrifugal wheel to prevent excessive oil accumulation on the wire rope under test during the test, which would affect its friction.

[0007] In a preferred embodiment of the present invention, a connecting frame is installed at the bottom of the elevator wire rope detector. The connecting frame is L-shaped, and several pairs of ribs are installed between the connecting frame and the outer shell of the elevator wire rope detector. The ribs are used to improve the connection strength. Several pairs of mounting holes are opened on the connecting frame, and the mounting holes are staggered on both sides of adjacent ribs. A guide roller is also installed on the elevator wire rope detector. The guide roller is used to make the wire rope to be tested fit tightly against the surface of the centrifugal wheel.

[0008] In a preferred embodiment of the present invention, the centrifugal wheel has an arc-shaped end, and a plurality of friction grooves are provided on the end face of the centrifugal wheel. A positioning shaft is installed at the rotation center of the centrifugal wheel, and a positioning seat is rotatably installed on the positioning shaft. The bottom of the positioning seat is welded to the side wall of the elevator wire rope detector.

[0009] In a preferred embodiment of the present invention, the synchronization component includes a synchronization plate, a pair of swing arms are rotatably mounted on the side wall of the synchronization plate, the ends of the swing arms are rotatably mounted on the end of the counterweight, the swing arms are in an inclined state, a guide rod is installed through the end of the counterweight, and slide seats are installed at both ends of the guide rod, the slide seats are welded to the end of the centrifugal wheel.

[0010] In a preferred embodiment of the present invention, a synchronization frame is rotatably mounted on the outer wall of the synchronization plate, a connecting shaft is rotatably mounted on the side wall of the synchronization frame, a rocker arm is mounted at the end of the connecting shaft, a sliding plate is mounted at the end of the rocker arm, the sliding plate is vertically slidably mounted on the side wall of the elevator wire rope detector housing, the rocker arm is in an inclined state, a connecting block is installed through the sliding plate, and the end of the connecting block is connected to the baffle.

[0011] In a preferred embodiment of the present invention, the elevator wire rope detector housing has a notch, the connecting block moves through the notch, a sealing plate is installed on the connecting block, the sealing plate is fitted to the side wall of the elevator wire rope detector housing, and the sealing plate is used to seal the notch.

[0012] In a preferred embodiment of the present invention, a limiting rod is installed through the inside of the connecting block, a limiting seat is installed at one end of the limiting rod, the limiting seat is installed on the housing of the elevator wire rope detector, a limiting plate is installed at the other end of the limiting rod, and a return spring is sleeved on the limiting rod. One end of the return spring is engaged with the limiting seat, and the other end of the return spring is engaged with the side wall of the connecting block.

[0013] In a preferred embodiment of the present invention, a fixing plate is installed on the sliding plate, an arched frame is installed on the fixing plate, a sliding rod is installed on the arched frame, an installation shaft is installed at the rotation center of the scraper, a pressure arm is installed on the installation shaft, a slot is formed on the pressure arm, and the sliding rod is slidably disposed inside the slot.

[0014] In a preferred embodiment of the present invention, the scraper has an inclined surface at its end, side plates are installed at both ends of the scraper, a mounting base is rotatably mounted on the mounting shaft, and the end of the mounting base is welded to the housing of the elevator wire rope detector.

[0015] An automated method for inspecting the wear of elevator wire ropes includes the following steps: Step 1: Device installation and debugging. Fix the device through the mounting holes of the connecting frame and enhance stability with the help of ribs; adjust the guide roller to make the steel wire rope to be tested fit with the centrifugal wheel, check the initial state, and ensure that the baffle blocks the visual detection probe, the reset spring extends and retracts naturally, and the scraper separates from the centrifugal wheel. Step 2: Trigger the linkage mechanism. The elevator runs and drives the steel wire rope under test to rise and fall, which in turn drives the centrifugal wheel to rotate synchronously around the positioning shaft; the counterweight slides along the guide rod under centrifugal force, which drives the swing arm to swing and triggers the synchronous component to start. Step 3: Detection preparation and protection work in tandem. Synchronous components drive the slide plate to slide vertically, causing the baffle to separate from the vision detection probe. At the same time, the scraper is driven to fit against the centrifugal wheel; the sealing plate seals the gap to prevent impurities from entering. Step 4: Steel wire rope wear detection. The visual inspection probe collects images of the steel wire rope surface and transmits them to the core processing module. The algorithm identifies defects such as wear and broken wires. The scraper simultaneously removes oil from the side wall of the centrifugal wheel to ensure stable transmission. Step 5: After the device reset and testing are completed, the centrifugal force disappears after the elevator stops, the reset spring pushes the connecting block to move in the opposite direction, and drives all components to reset; the detector records and stores the test results, completing the test cycle.

[0016] Compared with the prior art, the present invention has the following advantages: This invention automates the entire inspection process through the lifting and lowering motion of the elevator wire rope itself, eliminating the need for an additional power source and significantly reducing usage and maintenance costs. Specifically, through the contact transmission between the centrifugal wheel and the wire rope, combined with a counterweight and synchronization component, intelligent switching of the baffle can be achieved. This effectively blocks the visual inspection probe during non-inspection phases, isolating it from oil and dust contamination and ensuring inspection accuracy. During the inspection phase, the baffle automatically separates, ensuring timely probe operation. Furthermore, the synchronization component simultaneously drives a scraper to contact the side wall of the centrifugal wheel, scraping away oil accumulation in real time to prevent transmission failure due to decreased friction and to prevent missed detections. Overall, this significantly improves the reliability and accuracy of the inspection, providing strong protection for the safe operation of elevators.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0021] Example 1:

[0022] like Figures 1 to 8 As shown, an automated inspection device for the wear of elevator wire ropes includes an elevator wire rope detector 1, a visual inspection probe 2 is provided on the elevator wire rope detector 1, and the visual inspection probe 2 has a built-in visual sensor. The visual inspection probe 2 corresponds to the wire rope 7 to be tested.

[0023] The elevator wire rope tester 1 is equipped with a centrifugal wheel 8, which is in close contact with the wire rope 7 to be tested. During normal operation of the elevator, the centrifugal wheel 8 is rotated synchronously by the lifting and lowering of the wire rope 7 to be tested. A pair of counterweights 12 are slidably installed on the end face of the centrifugal wheel 8. A baffle 20 is also slidably installed on the elevator wire rope tester 1. The baffle 20 is used to block the visual inspection probe 2 during non-inspection time to prevent oil and dust from affecting the visual inspection probe 2. A synchronization component is connected between the counterweights 12 and the baffle 20. The synchronization component is used to drive the baffle 20 to separate from the visual inspection probe 2 during the rotation of the centrifugal wheel 8 to facilitate inspection. Inside the housing of the elevator wire rope tester 1, a scraper 27 is also rotatably installed, and the scraper 27 is synchronously connected to the synchronization component. The synchronization component is used to drive the scraper 27 to fit against the side wall of the centrifugal wheel 8, so as to prevent excessive oil from accumulating on the centrifugal wheel 8 during the test and affecting its friction.

[0024] like Figures 1 to 8 As shown in the specific embodiment, the elevator wire rope detector 1 has a connecting frame 3 installed at its bottom. The connecting frame 3 is L-shaped, and several pairs of ribs 4 are installed between the connecting frame 3 and the outer shell of the elevator wire rope detector 1. The ribs 4 are used to improve the connection strength. Several pairs of mounting holes 5 are opened on the connecting frame 3, and the mounting holes 5 are staggered on both sides of adjacent ribs 4. The elevator wire rope detector 1 is also equipped with a guide roller 6, which is used to ensure that the wire rope 7 to be tested is in close contact with the surface of the centrifugal wheel 8. Through the design of the L-shaped connecting frame 3, ribs 4 and staggered mounting holes 5, the installation stability and convenience of the device are improved. The guide roller 6 ensures the contact transmission between the wire rope 7 to be tested and the centrifugal wheel 8, laying the foundation for subsequent detection triggering.

[0025] like Figures 1 to 8 As shown, the centrifugal wheel 8 has an arc-shaped end, and several pairs of friction grooves are formed on the end face of the centrifugal wheel 8. A positioning shaft 9 is installed at the center of rotation of the centrifugal wheel 8, and a positioning seat 10 is rotatably mounted on the positioning shaft 9. The bottom of the positioning seat 10 is welded to the side wall of the elevator wire rope detector 1. The arc-shaped end and the design of the friction grooves enhance the friction between the centrifugal wheel 8 and the wire rope 7 to be tested. The cooperation between the positioning shaft 9 and the positioning seat 10 ensures the stability of the rotation of the centrifugal wheel 8 and ensures the accuracy of the transmission trigger.

[0026] like Figures 1 to 8As shown, in a specific embodiment, the synchronization component includes a synchronization plate 15. A pair of swing arms 14 are rotatably mounted on the side wall of the synchronization plate 15. The ends of the swing arms 14 are rotatably mounted on the ends of the counterweight 12. The swing arms 14 are in an inclined state. A guide rod 11 is installed through the interior of the end of the counterweight 12. Slide seats 13 are installed at both ends of the guide rod 11 and are welded to the ends of the centrifugal wheel 8. Through the linkage structure of the synchronization plate 15 and the swing arms 14, and the guiding and limiting of the guide rod 11 and the slide seats 13, the stable transmission of the sliding of the counterweight 12 and the movement of the synchronization component is realized, ensuring the precise operation of the linkage mechanism.

[0027] like Figures 1 to 8 As shown, a synchronization frame 16 is rotatably mounted on the outer wall of the synchronization plate 15. A connecting shaft 26 is rotatably mounted on the side wall of the synchronization frame 16. A rocker arm 17 is mounted at the end of the connecting shaft 26, and a slide plate 18 is mounted at the end of the rocker arm 17. The slide plate 18 is vertically slidably mounted on the side wall of the elevator wire rope detector 1 housing. The rocker arm 17 is in an inclined state. A connecting block 19 is installed through the slide plate 18, and the end of the connecting block 19 is connected to the baffle 20. Through the multi-stage linkage structure of the synchronization frame 16, the connecting shaft 26, the rocker arm 17, and the slide plate 18, the movement of the synchronization plate 15 is stably transmitted to the baffle 20, ensuring that the baffle 20 can accurately perform blocking and separation actions, and ensuring the reliability of the protection and detection switching of the visual inspection probe 2.

[0028] like Figures 1 to 8 As shown, the elevator wire rope detector 1 has a notch 21 in its outer casing. A connecting block 19 moves through the notch 21, and a sealing plate 37 is installed on the connecting block 19. The sealing plate 37 is fitted against the side wall of the elevator wire rope detector 1's outer casing and seals the notch 21. Through the cooperation between the sealing plate 37 and the notch 21, the outer casing of the device is sealed and protected during the movement of the connecting block 19, preventing impurities from entering the interior and affecting the operation of the components, thus improving the device's sealing performance and service life.

[0029] like Figures 1 to 8 As shown in the specific embodiment, a limiting rod 22 is installed through the connecting block 19. A limiting seat 24 is installed at one end of the limiting rod 22, which is mounted on the outer shell of the elevator wire rope detector 1. A limiting plate 23 is installed at the other end of the limiting rod 22. A return spring 25 is sleeved on the limiting rod 22. One end of the return spring 25 is engaged with the limiting seat 24, and the other end is engaged with the side wall of the connecting block 19. Through the limiting action of the limiting rod 22, the limiting seat 24, and the limiting plate 23, combined with the elastic return function of the return spring 25, the precise guidance and automatic return of the sliding of the connecting block 19 are achieved, ensuring the reliability of the baffle 20's reset action and preparing for the next detection cycle.

[0030] Example 2:

[0031] The difference between the above embodiments and this embodiment is that: Figures 1 to 8 As shown, further, a fixed plate 36 is installed on the slide plate 18, an arched frame 35 is installed on the fixed plate 36, a sliding rod 34 is installed on the arched frame 35, an installation shaft 30 is installed at the rotation center of the scraper 27, a pressure arm 32 is installed on the installation shaft 30, a slot 33 is formed on the pressure arm 32, the sliding rod 34 is slidably disposed inside the slot 33, an inclined surface 28 is formed at the end of the scraper 27, side plates 29 are installed at both ends of the scraper 27, and an installation seat 31 is rotatably installed on the installation shaft 30, the end of the installation seat 31 is welded to the housing of the elevator wire rope detector 1. Through the linkage structure of the fixed plate 36, the arched frame 35, the sliding rod 34 and the pressure arm 32, the synchronous drive of the slide plate 18 and the scraper 27 is realized. The inclined surface 28 and the side plates 29 improve the oil scraping effect, and the installation shaft 30 and the installation seat 31 ensure the rotational stability of the scraper 27, further improving the transmission reliability.

[0032] This invention also discloses an automated inspection method for the wear degree of elevator wire ropes, the steps of which are as follows: Step 1: Device installation and debugging. Fix the device through the mounting holes 5 of the connecting frame 3 and enhance stability with the help of the rib plate 4; adjust the guide roller 6 to make the steel wire rope 7 to be tested fit with the centrifugal wheel 8, check the initial state, and ensure that the baffle 20 blocks the visual detection probe 2, the reset spring 25 extends and retracts naturally, and the scraper 27 separates from the centrifugal wheel 8. Step 2: Trigger the linkage mechanism. The elevator runs and drives the steel wire rope 7 under test to rise and fall, which in turn drives the centrifugal wheel 8 to rotate synchronously around the positioning shaft 9; the counterweight 12 slides along the guide rod 11 under centrifugal force, which drives the swing arm 14 to swing and trigger the synchronous component to start. Step 3: Detection preparation and protection work in tandem. The synchronous components drive the slide plate 18 to slide vertically, causing the baffle 20 to separate from the visual inspection probe 2. At the same time, the scraper 27 is driven to fit against the centrifugal wheel 8. The sealing plate 37 seals the notch 21 to prevent impurities from entering. Step 4: Steel wire rope wear detection. The visual inspection probe 2 collects images of the steel wire rope surface and transmits them to the core processing module. Defects such as wear and broken wires are identified through algorithms. The scraper 27 simultaneously scrapes off the oil on the side wall of the centrifugal wheel 8 to ensure stable transmission. Step 5: After the device reset and testing are completed, the centrifugal force disappears after the elevator stops, the reset spring 25 pushes the connecting block 19 to move in the opposite direction, driving all components to reset; the tester records and stores the test results, completing the test cycle.

[0033] The implementation principle of the automated elevator wire rope wear inspection device of the present invention is as follows: Before the device is officially put into use, the entire device is fixedly installed at the corresponding detection position of the elevator through the mounting holes 5 on the L-shaped connecting frame 3 at the bottom of the elevator wire rope detector 1. During the installation process, the rib plate 4 between the connecting frame 3 and the outer shell of the elevator wire rope detector 1 is used to improve the installation connection strength. At the same time, the position of the wire rope 7 to be tested is adjusted so that the guide roller 6 guides the wire rope 7 to be tested to fit tightly against the surface of the centrifugal wheel 8 to ensure the stability of subsequent transmission. At this time, the baffle 20 is in the state of blocking the visual detection probe 2 to avoid oil and dust from contaminating the visual detection probe 2 during non-detection stages, thus ensuring the cleanliness of the detection element and the detection accuracy.

[0034] When the elevator is running normally, the steel wire rope 7 under test rises and falls accordingly. Because the steel wire rope 7 is in close contact with the centrifugal wheel 8, friction causes the centrifugal wheel 8 to rotate synchronously around the positioning shaft 9. The positioning shaft 9 is stably installed on the side wall of the elevator steel wire rope detector 1 via the positioning seat 10, providing reliable support for the rotation of the centrifugal wheel 8. As the centrifugal wheel 8 rotates, the counterweight 12 on its end face is subjected to centrifugal force and slides along the guide rod 11 away from the center of rotation. The guide rod 11 is fixed to the end of the centrifugal wheel 8 via the slide seat 13, ensuring the stability of the sliding trajectory of the counterweight 12. During the sliding process of the counterweight 12, it causes the swing arm 14, which is rotatably connected to it, to swing. Because the swing arm 14 is in an inclined state and its end is rotatably connected to the side wall of the synchronization plate 15, the swing of the swing arm 14 drives the synchronization plate 15 to make a horizontal synchronous displacement, thereby triggering the linkage action of the synchronization component.

[0035] When the synchronous plate 15 moves, it drives the synchronous frame 16, which is rotatably connected to its outer wall, to move. The synchronous frame 16 drives the rocker arm 17 to swing through the connecting shaft 26. The slide plate 18 connected to the end of the rocker arm 17 slides vertically along the side wall of the elevator wire rope detector 1. The slide plate 18 drives the baffle 20 to move synchronously through the connecting block 19, so that the baffle 20 gradually separates from the visual inspection probe 2. At this time, the visual inspection probe 2 is unobstructed and can normally perform visual inspection of the wear degree of the wire rope 7 to be tested below. During this process, the connecting block 19 moves along the notch 21 of the elevator wire rope detector 1. The sealing plate 37 on its surface always fits against the side wall of the shell to achieve sealing of the notch 21 and prevent external impurities from entering the device through the notch 21.

[0036] Simultaneously, when the slide plate 18 slides, it drives the fixed plate 36 on it to move synchronously. The arched frame 35 on the fixed plate 36 is displaced accordingly, which in turn drives the slide rod 34 on the arched frame 35 to slide in the slot 33 of the pressure arm 32, driving the pressure arm 32 to rotate around the mounting shaft 30. This causes the scraper 27 mounted on the mounting shaft 30 to rotate synchronously and fit tightly against the side wall of the centrifugal wheel 8. During the continuous rotation of the centrifugal wheel 8, the scraper 27 can scrape off the oil dripping from the surface of the steel wire rope 7 to be tested that is attached to the side wall of the centrifugal wheel 8 in real time, avoiding excessive oil accumulation that affects the friction between the centrifugal wheel 8 and the steel wire rope 7 to be tested, and ensuring the stability of the transmission between the two. The mounting shaft 30 is fixed to the housing of the elevator steel wire rope detector 1 through the mounting seat 31, ensuring that the scraping action of the scraper 27 is stable and reliable.

[0037] When the elevator stops running, the steel wire rope 7 under test no longer moves up or down, the centrifugal wheel 8 stops rotating, and the centrifugal force on the counterweight 12 disappears. At this time, the return spring 25 on the limit rod 22 begins to release elastic potential energy, pushing the connecting block 19 to move in the opposite direction. The connecting block 19 drives the synchronous plate 15 to move in the opposite direction through the rocker arm 17, the connecting shaft 26, and the synchronous frame 16. The synchronous plate 15 then drives the counterweight 12 to reset along the guide rod 11 towards the center of rotation through the swing arm 14. At the same time, the connecting block 19 drives the baffle 20 to move in the opposite direction, covering the visual inspection probe 2 again and forming protection again. The slide plate 18 also slides in the opposite direction, driving the mounting shaft 30 to rotate in the opposite direction through the fixed plate 36, the arched frame 35, the slide rod 34, and the pressure arm 32, causing the scraper 27 to separate from the side wall of the centrifugal wheel 8, ending the scraping action and completing one complete automated inspection cycle.

[0038] The entire process requires no additional power. It utilizes the kinetic energy of the steel wire rope 7 under test during elevator operation to achieve synchronous linkage of all components. This not only perfectly adapts to the elevator's working environment, enabling precise triggering of the detection only when the elevator is running, but also ensures that the steel wire rope 7 moves synchronously during this time, covering the entire trajectory of the rope and guaranteeing comprehensive detection. Simultaneously, after the visual inspection probe 2 is unobstructed, its built-in visual sensor collects real-time surface image information of the steel wire rope 7 and transmits the image data to the core processing module of the elevator steel wire rope detector 1. Through image comparison, feature analysis, and other algorithms, it accurately identifies the wear level, broken wires, and other defects of the steel wire rope, achieving automated detection of steel wire rope wear. This design achieves automated triggering of the detection process and autonomous protection during non-detection phases, effectively improving the convenience and reliability of elevator steel wire rope wear detection.

10. An automated method for inspecting the wear of elevator wire ropes, characterized in that, An automated elevator wire rope wear inspection device according to any one of claims 1 to 9, and an automated elevator wire rope wear inspection method, comprising the following steps: Step 1: Device installation and debugging. Fix the device through the mounting holes (5) of the connecting frame (3) and enhance stability with the help of the rib plate (4); adjust the guide roller (6) to make the steel wire rope (7) to be tested fit with the centrifugal wheel (8), check the initial state, and ensure that the baffle (20) blocks the visual detection probe (2), the reset spring (25) extends and retracts naturally, and the scraper (27) separates from the centrifugal wheel (8); Step 2: Trigger the linkage mechanism. The elevator runs and drives the steel wire rope (7) under test to rise and fall, which in turn drives the centrifugal wheel (8) to rotate synchronously around the positioning shaft (9); the counterweight (12) slides along the guide rod (11) under centrifugal force, which drives the swing arm (14) to swing and trigger the synchronous component to start. Step 3: Detection preparation and protection work together. The synchronous components drive the sliding plate (18) to slide vertically, causing the baffle (20) to separate from the visual inspection probe (2). At the same time, the scraper (27) is driven to fit with the centrifugal wheel (8); the sealing plate (37) seals the gap (21) to prevent impurities from entering. Step 4: Steel wire rope wear detection. The visual inspection probe (2) collects images of the steel wire rope surface and transmits them to the core processing module. The algorithm identifies defects such as wear and broken wires. The scraper (27) simultaneously scrapes off the oil on the side wall of the centrifugal wheel (8) to ensure stable transmission. Step 5: After the device is reset and the test is completed, the centrifugal force disappears after the elevator stops, the reset spring (25) pushes the connecting block (19) to move in the opposite direction, and drives each component to reset; the tester records and stores the test results, and completes the test cycle.
