Description

Technical Field

[0001] This invention relates to the field of elevator traction sheave wear detection technology, specifically to an elevator traction sheave wear detection device. Background Technology

[0002] Elevator traction sheaves typically consist of a rim, hub, and spokes. The rim has grooves to hold the traction steel wire rope. The shape and material of these grooves directly affect friction and the lifespan of the wire rope. Common groove types include semi-circular grooves, V-shaped grooves, and semi-circular grooves with notches.

[0003] During use, the grooves of existing elevator traction sheaves require regular inspection to check for flatness, cracks, or excessive wear. However, current methods using measuring rulers and visual inspection present several problems: 1. The root area (approximately 5-10mm deep) where the groove contacts the wire rope is difficult to observe directly, easily leading to missed cracks or wear; 2. Minor deformations or fatigue cracks on the side of the groove (the friction surface with the wire rope) are difficult to detect visually; 3. When measuring the groove depth using calipers or depth gauges, errors can reach ±0.2mm due to uneven groove surfaces or improper operation. Long-term accumulation can lead to uneven wire rope tension or slippage. Therefore, we propose a wear detection device for elevator traction sheaves. Summary of the Invention

[0004] The purpose of this invention is to provide a device for detecting the wear of elevator traction sheaves, so as to solve the problems mentioned in the background art.

Through the provided detection component, the wear amount of the traction wheel groove can be accurately detected.

[0013] Furthermore, the alignment component includes an alignment protrusion, which is fixedly mounted on the inspection bracket. When the connecting ball rotates to the alignment protrusion, the connecting ball slides in connection with the alignment protrusion. Through the provided alignment component, the connecting ball is pushed.

[0014] Furthermore, the synchronous transmission mechanism includes a gear transmission assembly, a synchronous intermittent assembly, a support shaft, a rotating plate, a rotating shaft, a movable frame, and a rust removal component.

[0015] The inspection bracket is provided with a support port, and the movable frame slides through the support port. The rust removal component is installed on the inspection bracket and is used to remove rust from the groove of the traction wheel, thereby realizing the synchronous drive of the synchronous shaft.

[0016] Furthermore, the rotating shaft is offset from the center of the rotating plate, thereby ensuring that the rotating shaft drives the moving frame.

[0022] 2. The detection component in the invention utilizes the drive of the traction wheel for synchronous drive detection, eliminating the need for additional drive force and achieving high efficiency and energy saving.

[0023] 3. The synchronous transmission mechanism in this invention not only drives the detection component but also provides intermittent driving for the detection component.

Detailed Implementation

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Example 1

[0044] Please see Figures 1 to 4 A wear detection device for an elevator traction sheave includes an inspection bracket 1, which is fixedly connected to the mounting base of the traction sheave 2 by bolts. One end of the inspection bracket 1 is rotatably connected to a rotating shaft 3, and the rotating shaft 3 is located directly below the traction sheave 2. A detection component 4 is installed on the rotating shaft 3, and the detection component 4 is used to automatically detect the wear at the groove of the traction sheave 2.

[0045] A synchronous transmission mechanism 5 is installed on the inspection bracket 1. The synchronous transmission mechanism 5 is connected to the detection component 4, and the synchronous transmission mechanism 5 drives the detection component 4 to rotate for detection. A synchronous shaft 6 is rotatably connected to the synchronous transmission mechanism 5, and the synchronous shaft 6 is fixedly connected to one side of the traction wheel 2 by bolts.

[0046] Please see Figures 4 to 8 The detection component 4 includes a fixed sleeve 41, a fixed plate 42, a fixed shell 43, an adjusting component 44, a branch shell 45, and a detection component 46. The fixed sleeve 41 is fixedly sleeved on the outside of the rotating shaft 3. There are three fixed plates 42, which are equidistantly fixed around the outside of the fixed sleeve 41. The side of the fixed plate 42 away from the fixed sleeve 41 is fixedly connected to the fixed shell 43. The adjusting component 44 is set on the fixed shell 43, and the inspection bracket 1 is provided with an alignment component 47.

[0047] Multiple branch shells 45 are provided, and multiple branch shells 45 are installed at equal distances on the side of the fixed shell 43 away from the fixed plate 42. The branch shells 45 are connected to the fixed shell 43, and the branch shells 45 correspond to the wheel grooves of the traction wheel 2. The detection element 46 is installed at the branch shell 45, and multiple detection elements 46 are connected to the adjustment element 44.

[0048] The adjusting component 44 includes a connecting shaft 441, a connecting ball 442, a pusher frame 443, a connecting spring 444, a positioning plate 445, and a pusher block 446. The connecting shaft 441 slides through one end of the fixed housing 43, and the end of the connecting shaft 441 located outside the fixed housing 43 is fixedly connected to the connecting ball 442. The other end of the connecting shaft 441 is fixedly connected to the pusher frame 443.

[0049] The push frame 443 is U-shaped, and multiple moving ports are provided at equal distances on both sides of the push frame 443. The connecting spring 444 is located at the moving port, and the two ends of the connecting spring 444 are fixedly connected to the moving port and the positioning plate 445 respectively. The positioning plate 445 is fixedly connected to the fixed shell 43.

[0050] Multiple pusher blocks 446 are provided, and the multiple pusher blocks 446 are installed at equal distances on the pusher frame 443. The pusher blocks 446 are connected to the detection piece 46.

[0051] Please see Figures 4 to 8 The detection component 46 includes a detection plate 461, a limiting plate 462, a limiting spring 463, and a laser sensor 464. The detection plate 461 slides through one end of the branch shell 45, and the laser sensor 464 is mounted on the detection plate 461. The other end of the detection plate 461 is slidably connected to the pushing inclined block 446. The detection plate 461 has a positioning port, and the limiting plate 462 slides through the positioning port. Both ends of the limiting plate 462 are fixedly connected to the branch shell 45. Both ends of the limiting spring 463 are fixedly connected to the positioning plate 445 and the limiting plate 462, respectively. In this invention, the installation positions of the laser sensors 464 on the three fixed shells 43 are different. For example, one fixed shell... Multiple laser sensors 464 on the fixed housing 43 are all mounted on the left side, multiple laser sensors 464 on another fixed housing 43 are mounted on the right side, and multiple laser sensors 464 on the third fixed housing 43 are all facing the groove of the traction sheave 2. This arrangement enables high-precision laser detection of both sides and the inside of the groove of the traction sheave 2. During detection, the laser sensor 464 emits a laser beam to a surface of the corresponding groove, and the reflected light is focused by the optical system onto the CMOS image sensor. When wear occurs on the surface of the groove, the position of the reflected light spot shifts accordingly, and the sensor accurately determines the wear depth and width by calculating the shift.

[0052] The alignment member 47 includes an alignment protrusion 471, which is fixedly installed on the inspection bracket. When the connecting ball 442 rotates to the alignment protrusion 471, the connecting ball 442 and the alignment protrusion 471 are slidably connected. Meanwhile, the alignment protrusion 471 in this invention is arc-shaped.

[0053] Specific detection process: In this invention, when the traction wheel 2 pulls the wire rope through the wheel groove, the rotation of the traction wheel 2 synchronously drives the synchronous transmission mechanism 5 to run. When the synchronous transmission mechanism 5 runs, it drives the rotating shaft 3 to rotate. When the rotating shaft 3 rotates, it drives the three fixed shells 43 to rotate synchronously through the fixed sleeve 41 and the three fixed plates 42 respectively. When the connecting ball 442 at one of the fixed shells 43 rotates to the position of the aligned protrusion 471, the connecting ball 442 causes multiple pushing inclined blocks 446 to move relative to the inside of the fixed shell 43 through the connecting shaft 441 and the pushing frame 443. When the pushing inclined blocks 446 move, they push the detection plate 461. Under the limiting action of the limiting plate 462 and the connection of the limiting spring 463, the multiple detection plates 461 at the fixed shell 43 move towards the wheel groove of the traction wheel 2, so that the laser sensor 464 at the detection plate 461 can accurately align at the wheel groove for high-precision detection.

[0054] The synchronous transmission mechanism 5 includes a gear transmission assembly 51, a synchronous intermittent assembly 52, a support shaft 53, a rotating plate 54, a rotating shaft 55, a movable frame 56, and a rust removal component 57. The gear transmission assembly 51 is connected to the synchronous shaft 6. The support shaft 53 passes through one side of the inspection bracket 1 and is rotatably connected to the inspection bracket 1. The synchronous intermittent assembly 52 is connected to the support shaft 53 and is also connected to the gear transmission assembly 51. One end of the support shaft 53 is fixedly connected to the rotating plate 54, and the rotating shaft 55 is fixedly installed on one side of the rotating plate 54. The movable frame 56 has an opening, and the rotating shaft 55 slides through the opening.

[0055] The inspection bracket 1 is provided with a support port, and the movable frame 56 slides through the support port. The rust removal part 57 is installed on the inspection bracket 1 and is used to remove rust from the groove of the traction wheel 2. The rotating shaft 55 is offset from the center of the rotating plate 54.

[0056] The rust removal component 57 includes a rust removal scraper 571. Multiple rust removal scrapers 571 are provided, and each of the multiple rust removal scrapers 571 corresponds to a multiple groove of the traction sheave 2. The rust removal scraper 571 includes an installation end 5711 and a scraping end 5712. The installation end 5711 is fixedly installed on the movable frame 56, and the scraping end 5712 is arc-shaped. In this embodiment, for the groove of the traction sheave 2, that is, the groove that is V-shaped or U-shaped, the scraping end 5712 of the rust removal scraper 571 is correspondingly provided to achieve the function of fully scraping the groove.

[0057] Multiple rust-removing scrapers 571 are provided with matching scrapers 7 on their outer sides. The matching scrapers 7 are provided with matching openings 71, and the matching scrapers 7 are fitted onto the outer sides of the multiple rust-removing scrapers 571 through the matching openings 71. A matching frame 72 is fixedly connected to one side of the matching scraper 7, and the matching frame 72 is slidably connected to the inspection bracket 1. A reciprocating part 73 is provided at the bottom of the matching frame 72, and the reciprocating part 73 is connected to the support shaft 53.

[0058] The reciprocating component 73 includes a reciprocating wheel 731, a guide ring 732, and a guide rod 733. The reciprocating wheel 731 is fixedly sleeved on the outside of the support shaft 53, and the guide ring 732 is fixedly sleeved on the outside of the reciprocating wheel 731. There are two guide rods 733, which are located below the reciprocating wheel 731 and are slidably connected to the guide ring 732. Both guide rods 733 are fixedly installed on the mating frame 72.

[0059] Specific implementation process: When the support shaft 53 rotates, the rotating plate 54 drives the rotating shaft 55 to rotate. The rotating shaft 55 pushes the moving frame 56 through the opening. At the same time, due to the limiting effect of the support opening, the moving frame 56 reciprocates relative to the support opening. While the moving frame 56 is reciprocating, it drives multiple rust-removing scrapers 571 to move and disengage from multiple wheel grooves. When the rust-removing scraper 571 moves relative to the wheel groove, the wheel groove rotates a certain number of times relative to the rust-removing scraper 571, and the rust-removing scraper 571 deviates from the wheel groove. When the rust-removing scraper 571 deviates from the wheel groove, the cooperating scraper 7 is located outside the multiple rust-removing scrapers 571. Under the connection of the reciprocating part 73, the multiple cooperating scrapers 7 cooperate with the rust-removing scrapers 571 to remove rust particles from the outside of the rust-removing scraper 571.

[0060] Example 2

[0061] Please see Figures 9 to 13 Embodiment 2 further describes the gear transmission assembly 51 in Embodiment 1. Specifically, the gear transmission assembly 51 includes a pinion 511, a large gear 512, a fixed shaft 513, a first rotating gear 514, a second rotating gear 515, a gear chain 516, and a driven shaft 517. The pinion 511 is fixedly sleeved on the outside of one end of the synchronous shaft 6, and the pinion 511 is meshed with the large gear 512. The fixed shaft 513 is rotatably connected to the inspection bracket 1, and the large gear 512 is fixedly installed on the fixed shaft 513. The first rotating gear 514 is fixedly sleeved on the outside of the fixed shaft 513, and the first rotating gear 514 is connected to the second rotating gear 515 through the gear chain 516. The driven shaft 517 is rotatably connected to the inspection bracket 1, and the second rotating gear 515 is fixedly sleeved on the driven shaft 517. The synchronous intermittent assembly 52 is connected to the driven shaft 517.

[0062] Specifically, when the synchronous shaft 6 rotates synchronously with the traction wheel 2, the synchronous shaft 6 drives the pinion 511 to rotate synchronously, and the pinion 511 drives the large gear 512 to rotate. When the large gear 512 rotates, it drives the second rotating gear 515 to rotate through the first rotating gear 514 and the gear chain 516, which further causes the driven shaft 517 to rotate relative to the inspection bracket 1, thereby driving the synchronous intermittent assembly 52 to run.

[0063] Example 3

[0064] Please see Figures 9 to 13Example 3 further describes the synchronous intermittent assembly 52 in Examples 1 and 2. Specifically, the synchronous intermittent assembly 52 includes an intermittent wheel 521, an intermittent rod 522, an intermittent plate 523, a synchronous sleeve 524, a rotating plate 525, and a linkage 8. The intermittent wheel 521 is fixedly sleeved on the outside of the driven shaft 517. Both sides of the intermittent wheel 521 are provided with extension edges, and the intermittent rod 522 is fixedly installed between the two extension edges. The intermittent plate 523 is fixedly sleeved on the outside of one end of the support shaft 53. The outer periphery of the intermittent plate 523 is provided with multiple arc-shaped grooves, and a swing opening is provided between two adjacent arc-shaped grooves. The intermittent wheel 521 is slidably connected to one of the arc-shaped grooves, and the intermittent rod 522 is slidably connected to one of the swing openings.

[0065] One end of the synchronizing sleeve 524 is fixedly connected to the intermittent plate 523, and the other end of the synchronizing sleeve 524 is fixedly connected to the rotating plate 525. The linkage 8 is installed between the rotating plate 525 and the rotating shaft 3.

[0066] The linkage 8 includes a connecting rod 81 and a swing rod 82. One end of the connecting rod 81 is rotatably connected to the rotating plate 525 via a pin, and the position where the connecting rod 81 is connected to the rotating plate 525 is offset from the center of the rotating plate 525. The other end of the connecting rod 81 is rotatably connected to the swing rod 82 via a pin, and a positioning shaft 83 is rotatably connected to the bottom of the swing rod 82. The positioning shaft 83 is fixedly installed on the inspection bracket 1. An extension shaft 84 is fixedly connected to the swing rod 82, and a ratchet 85 is rotatably sleeved on the outside of the extension shaft 84. A ratchet 86 is meshed on the outside of the ratchet 85, and the ratchet 86 is fixedly sleeved on the outside of one end of the rotating shaft 3.

[0067] Specific implementation process: When the driven shaft 517 rotates, it drives the intermittent wheel 521 to rotate synchronously. The intermittent wheel 521 then drives the intermittent plate 523 to rotate intermittently through the intermittent rod 522. When the intermittent plate 523 rotates, on the one hand, the support shaft 53 rotates relative to the inspection bracket 1, and on the other hand, it drives the rotating plate 525 to rotate synchronously through the synchronous sleeve 524. Due to the limiting effect of the positioning shaft 83, the rotating plate 525 drives the swing support rod 82 to swing through the connecting support rod 81. At this time, the swing support rod 82 drives the ratchet 86 to rotate intermittently through the ratchet 85. When the ratchet 86 rotates, it drives the detection component 4 to rotate and detect through the rotating shaft 3.
