Description

Technical Field

[0001] The present invention relates to the field of traction wheels, and particularly to a wear performance detection device for an elevator traction wheel. Background Art

[0002] A traction wheel is a rope wheel on a traction machine, also known as a traction rope wheel or a drive rope wheel, which is a device for transmitting the traction power of an elevator and uses the friction between the traction steel wire rope and the rope groove on the edge of the traction wheel to transmit power.

[0003] Currently, in the existing elevator car and counterweight device, generally multiple steel wire ropes are connected and the steel wire ropes are driven to move by a traction wheel to realize the up and down movement of the elevator car in the hoistway. During the repeated up and down movement of the elevator car, the rope groove of the traction wheel will be worn. In order to avoid accidents caused by the wear of the traction wheel, the staff needs to regularly use a wear performance detection device to detect the wear of the rope groove of the traction wheel.

[0004] In the related art, for a mobile traction wheel wear performance detection device, its use process is as follows: First, manually use a scraper to enter and exit the inner wall of the rope groove, and control the rotation of the traction wheel to clean the dirt in the rope groove to avoid the dirt affecting the detection accuracy. Then, manually hold the detection device and make its detection head contact the inner wall of the rope groove at the lower end position of the traction wheel. Control the rotation of the traction wheel again so that the detection head can contact different positions of the rope groove. Utilize the extrusion effect generated when the detection head contacts the rope groove, and finally the wear degree of the rope groove can be measured. However, this detection device still has certain deficiencies in the actual use process: Since the space at the lower end of the traction wheel is relatively narrow, the staff cannot directly observe the specific position of the rope groove. Therefore, when cleaning the dirt, the staff can only sense the approximate position of the rope groove by hand and then use the scraper to clean the dirt. This method not only has a large operation difficulty, slow cleaning speed, but also cannot ensure effective contact between the scraper and the rope groove, resulting in poor cleaning effect and inaccurate final detection accuracy.

[0010] Preferably, a scale line is arranged on the horizontal section of the positioning plate piece, and a scale pointer pointing to the scale line is fixedly connected to the top of the horizontal section of the support plate near one end of the rotating piece.

[0011] Preferably, clamping holes are formed on both the upper and lower sides of the end of the rotating member close to the support plate.

The top of the clamping shaft is clamped with one of the clamping holes. A support spring is fixedly connected between the pressing member and the chute.

[0013] Preferably, a positioning plate is fixedly connected to one end of the bottom of the base close to the support plate. A tightening and fixing member is threadedly connected through the bottom of the positioning plate.

[0014] Compared with the related art, the elevator traction wheel wear performance detection device provided by the embodiment of the present invention has the following beneficial effects:

[0015] (1) By providing a rotating member, a detection component, a cleaning component and a positioning component to form a detection device, the functions of cleaning the dirt in the traction wheel groove and detecting the wear degree can be realized. Among them, by setting the cleaning component and the positioning component to cooperate with each other, when cleaning the dirt in the wheel groove, the positioning component is used to contact the side of the traction wheel to determine the alignment position of the cleaning component and the wheel groove. On the one hand, the cleaning component and the wheel groove can be accurately aligned, ensuring that the cleaning component can effectively contact the wheel groove, cleaning the dirt more thoroughly, eliminating the influence of the dirt on the wear detection of the wheel groove, and thus increasing the accuracy of the detection component; on the other hand, when performing the position alignment operation, only need to push the detection device towards the traction wheel, which not only speeds up the operation speed, but also greatly reduces the operation difficulty of aligning the cleaning component and the wheel groove position, is no longer restricted by the space around the traction wheel, and is more convenient for detecting the traction wheel;

[0016] (2) By respectively arranging the cleaning component and the detection component at the top and bottom positions of the rotating member, after the cleaning component finishes cleaning the dirt in the wheel groove, the detection component can be directly moved into the wheel groove by rotating the rotating member. On the one hand, when the rotating member rotates, its fixed position will not change, and the positions of the detection component and the cleaning component are set corresponding to each other up and down. Therefore, after rotating the rotating member by 180 degrees, the detection component can quickly reach the wheel groove position and can be accurately aligned with the wheel groove, further ensuring the accuracy of the detection component for detecting the wheel groove; on the other hand, there is no need to repeatedly align the positions of the detection component and the wheel groove. After the dirt in the wheel groove is cleaned, the detection operation can be immediately performed, which is more convenient to operate;

[0017] (3) By setting the locking component, it can be used to lock the position of the rotating part. On the one hand, when using the detection component to detect the wheel groove, the rotating part will not rotate, making the detection component in a stable state, avoiding affecting its detection accuracy. At the same time, during the process of adjusting the detection component to contact with the wheel groove, through the clamping action of the clamping shaft and the clamping hole, the rotation position can be automatically determined, avoiding deviation of the rotation angle and ensuring the alignment accuracy between the detection component and the wheel groove. On the other hand, when the cleaning component is used to clean the dirt in the wheel groove, keeping the position of the cleaning component unchanged can make the cleaning effect of the cleaning component better.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Embodiments of the present invention will be described below with reference to the accompanying drawings. During this process, to ensure clarity and convenience of the description, we may exaggerate the widths of the lines or the sizes of the components in the drawings.

[0026] In addition, the terms in the following text are defined based on the functions in the present invention and may vary according to the intention or convention of the user; therefore, these terms are defined based on the entire content of this specification.

[0027] Please refer to Figure 1 and Figure 4 , an elevator traction wheel wear performance detection device, comprising: a base 1, a support plate 2 arranged in an inverted L shape is vertically and fixedly connected to the top of the base 1, and a clamping plate 5 arranged in an L shape is fixedly connected to one end of the bottom of the base 1 near the support plate 2. The horizontal section of the clamping plate 5 and the bottom of the base 1 form a clamping area. When using the detection device, place the base 1 flat on the base 8 where the traction wheel 7 is fixed, and snap this clamping area onto the base 8 so that the base 1 is effectively connected to the base 8. A tightening and fixing member 6 is threadedly connected through the bottom of the clamping plate 5. The tightening and fixing member 6 consists of a top plate located above the horizontal section of the clamping plate 5 and a threaded member. By rotating the threaded member, the top plate can move in the vertical direction, and the top plate can be brought into contact with the base 8 to further fix the base 1.

[0028] Please refer to Figure 1 , Figure 2 and Figure 3, a detection mechanism 3 for detecting the wheel groove of the traction wheel 7 is rotatably connected to the support plate 2. The detection mechanism 3 includes a positioning member 31 and a rotating member 32 vertically and rotatably mounted on the support plate 2. The positioning member 31 is arranged on the horizontal section of the support plate 2. One end of the rotating member 32 is fixedly installed with a rotating member 33 along the length direction of the base 1. The rotating member 33 is a cuboid structure parallel to the base 1. A cleaning member 34 for cleaning the dirt in the wheel groove of the traction wheel 7 is movably arranged on the top of the rotating member 33. The positioning member 31 is used to position the moving position of the cleaning member 34. A detection member 35 for detecting the inner side wall of the wheel groove of the traction wheel 7 is arranged at the bottom of the rotating member 33. When the detection device is moved to the lower end of the traction wheel 7 and aligned with the wheel groove position, by pushing the base 1 to move on the base 8 fixed to the traction wheel 7, with one end of the positioning member 31 contacting the side of the traction wheel 7, the final fixed position of the support seat is determined. After determining the position of the support seat, the cleaning member 34 can be driven to contact the wheel groove, so that the cleaning member 34 cleans the dirt in the wheel groove. After the cleaning is completed, by manually rotating the rotating member 32, the rotating member 33, the cleaning member 34 and the detection member 35 can be rotated together. After rotating 180 degrees, the detection member 35 is made to contact the wheel groove, realizing that the cleaning member 34 and the detection member 35 quickly change their vertical positions on the premise that the original horizontal fixed position remains unchanged, so that the detection member 35 can automatically align with the wheel groove.

[0029] Please refer to Figure 1 and Figure 4 , a movable groove 36 is formed at the top of the rotating member 33. The cleaning member 34 includes two electromagnet groups 341 and a movable plate 342 slidably installed in the movable groove 36. The two electromagnet groups 341 are respectively and fixedly installed at the bottom of the movable plate 342 and the bottom wall of the movable groove 36 up and down. The electromagnet group 341 is composed of two left and right symmetric electromagnet groups 341, and the magnetic poles generated after the two electromagnet groups 341 are energized are the same. Therefore, under the magnetic force of the two electromagnet groups 341, the movable plate 342 can be driven to move upward. Five decontamination members 343 are uniformly fixedly connected to the top of the movable plate 342 along its length direction. The decontamination members 343 contact the wheel groove of the traction wheel 7. After the traction wheel 7 rotates, the dirt in the wheel groove can be scraped off by friction with the wheel groove of the traction wheel 7. And the number of the decontamination members 343 is set according to the number of the wheel grooves, not limited to five, and can be adjusted according to the actual use situation;

[0030] Please refer to Figure 4 and Figure 5, the dirt removing member 343 includes an inner support piece 3431 vertically and fixedly installed on the top of the movable plate 342. The inner support piece 3431 can be made of materials such as aluminum alloy and stainless steel. An air inlet cavity 3432 is provided inside the inner support piece 3431. A flexible scraping member 3433 is fixedly sleeved on the outer side of the inner support piece 3431. The top ends of both the inner support piece 3431 and the scraping member 3433 are set to be arc-shaped. The inner support piece 3431 supports the flexible scraping member 3433, so that it will not change greatly when contacting the wheel groove. The scraping member 3433 is made of rubber material with good anti-friction performance, which can reduce the wear of the wheel groove. An expansion cavity 3434 is provided inside the scraping member 3433. The air inlet cavity 3432 and the expansion cavity 3434 are connected through a plurality of conduits. The conduits are evenly distributed on the inner side wall of the expansion cavity 3434, and can evenly introduce gas into the expansion cavity 3434, so that the scraping member 3433 can expand evenly. The air outlet end on the air inlet pipe 347 is connected to the lower end of the air inlet cavity 3432, and gas can be respectively introduced into the five air inlet cavities 3432 to realize the function of synchronously adjusting the sizes of the five scraping members 3433. A cylinder 344 is fixedly connected to the bottom of the movable plate 342. The inside of the cylinder 344 is in a sealed state and stores air. One end of the cylinder 344 is fixedly connected to an electric push rod 345. The telescopic end of the electric push rod 345 is slidably installed inside the cylinder 344 and fixedly connected to a piston block 346. An air inlet pipe 347 is horizontally provided inside the movable plate 342. One end of the air inlet pipe 347 is connected to the air outlet end of the cylinder 344. The five air outlet ends on the air inlet pipe 347 are respectively connected to the five dirt removing members 343. Two symmetrically arranged tension springs 348 are fixedly connected between the bottom of the movable plate 342 and the bottom wall of the movable groove 36. The detection component 35 is composed of five detection heads arranged side by side and evenly distributed along the length direction of the rotating member 33. The number of detection heads is the same as the number of dirt removing members 343, and the positions of the five dirt removing members 343 and the five detection heads are in one-to-one correspondence up and down. It is a conventional choice for those skilled in the art to realize the detection function of the wear degree of the wheel groove by the detection component 35 through the contact between the detection heads and the wheel groove, which belongs to the prior art, and its working principle will not be elaborated here.

[0031] Before using the decontamination member 343 to clean the groove of the traction wheel 7, the entire cleaning member 34 is contracted inside the movable groove 36. During use, by energizing two electromagnets to generate the same magnetic force, the movable plate 342 and the five decontamination members 343 can be driven to move upward together, and the tension spring 348 is also stretched simultaneously until the top of the movable plate 342 extends outside the rotating member 33. The magnetic force of the two electromagnet groups 341 no longer increases, causing the decontamination member 343 and the movable plate 342 to remain fixed. If the staff finds that the groove is severely worn, the size of the decontamination member 343 can be adjusted first. During adjustment, by extending the electric push rod 345, the piston block 346 can slide inside the air cylinder 344 and squeeze the gas inside it, causing the gas to be discharged into the intake cavity 3432 through the intake pipe 347 and then enter the expansion cavity 3434 through the conduit. Finally, the scraping member 3433 expands uniformly, increasing its size to ensure that the outside of the scraping member 3433 can be in close contact with the groove and effectively clean the dirt on the groove.

[0032] Please refer to Figure 1 and Figure 4 , the positioning member 31 includes an adjusting rotating member 311 horizontally and rotatably installed on the horizontal section of the support plate 2. The outside of the adjusting rotating member 311 is threadedly connected with a positioning plate member 312 arranged in an L-shaped structure and slidably installed on the horizontal section of the support plate 2. The adjusting rotating member 311 is a threaded rotating rod, and one end of it extends to the end of the horizontal section of the support plate 2 away from the decontamination member 343. The upper end of the vertical section of the positioning plate member 312 is fixedly connected with a laser emitter 313 that emits a laser beam upward. After the positioning plate member 312 contacts the outside of the traction wheel 7, by starting the laser generator to generate a linear laser beam, based on this laser beam, the position of the detection device is horizontally adjusted so that the laser beam coincides with the circular position of the traction wheel 7, ensuring that the detection device reaches the lower end position of the traction wheel 7, enabling the decontamination member 343 and the detection head to be in perpendicular contact with the groove, resulting in a better scraping effect and higher detection accuracy; there are scale lines on the horizontal section of the positioning plate member 312, and the scale on this scale line represents the distance between the vertical section of the positioning plate member 312 and the center of the decontamination member 343 closest to the vertical section of the positioning plate member 312. The top of the horizontal section of the support plate 2 is fixedly connected with a scale pointer 314 pointing to the scale line near the rotating member 33; since the present invention is used directly below the traction wheel 7, the staff cannot clearly judge the position of the groove. Therefore, before fixing the position of the detection device, the staff needs to first refer to the equipment parameters of the traction wheel 7 to determine the distance between the center position of the groove of the traction wheel 7 and the side position of the traction wheel 7, that is Figure 2The distance a shown is then used to correspondingly adjust the extension length of the positioning plate 312. Since the scraping member 3433 is arranged corresponding to the position of the wheel groove, after adjusting the distance between the center position of the scraping member 3433 and the vertical section of the positioning plate 312 to a as well, when the detection device is pushed to move horizontally, when the vertical section of the positioning plate 312 contacts the side of the traction wheel 7, the center position of the scraping member 3433 is exactly aligned vertically with the wheel groove, thereby realizing the quick position alignment function between the scraping member 3433 and the wheel groove.

[0033] Please refer to Figure 4 , clamping holes 37 are formed on both the upper and lower sides of the end of the rotating member 33 close to the support plate 2. A through chute 4 is formed on the vertical section of the support plate 2. The detection mechanism 3 further includes a locking member 38 arranged on the vertical section of the support plate 2. The locking member 38 includes a pressing member 381 slidably installed through the chute 4. Protrusion structures are arranged on both sides of the pressing member 381 sliding in the chute 4. By respectively slidingly connecting the two protrusion structures with the inner side walls on both sides of the chute 4, the pressing member 381 can be limited and prevented from disengaging from the chute 4. One end of the pressing member 381 close to the rotating member 33 is fixedly connected with a clamping shaft 382. The top of the clamping shaft 382 is clamped with one of the clamping holes 37. A support spring 383 is fixedly connected between the pressing member 381 and the chute 4. The locking member 38 is mainly used to lock the position of the rotating member 33 to ensure that when the decontamination scraping member or the detection member 35 contacts the wheel groove, the rotating member 33 will not rotate and affect the action effect of the decontamination member 343 or the detection member 35.

[0034] The working principle of the elevator traction wheel wear performance detection device provided by the embodiment of the present invention is as follows:

[0035] Step 1: During use, first remove the protective cover outside the traction wheel 7 to expose the traction wheel 7. Then, the staff refers to the relevant parameter manual of the traction wheel 7 to determine the distance from the center of the wheel groove of the traction wheel 7 to its side, or uses a high-precision measuring instrument for measurement. Next, by manually rotating and adjusting the rotating member 311, the positioning plate 312 can be moved horizontally on the support plate 2. At the same time, the staff determines the adjustment position by observing the position change of the scale pointer 314 and the scale line. After reaching the required position, stop rotating the rotating member 32 to keep the positioning plate 312 in a fixed state;

[0036] Step 2: Next, place the detection device flat on the base 8 fixed at the bottom of the traction sheave 7, turn on the laser emitter 313, place the detection device below the traction sheave 7, then push the base 1 so that the positioning plate 312 approaches the side of the traction sheave 7 until they finally come into contact. Then, further determine the position of the detection device according to the laser beam so that the detection device is directly below the traction sheave 7. Then, manually rotate and tighten the fixing member 6 to fix its top to the base 8 fixed at the bottom of the traction sheave 7, so that the entire detection device can be kept in a fixed state;

[0037] Step 3: Then, energize the two electromagnet groups 341 to generate the same magnetic poles, so that the movable plate 342 and the scraping member 3433 move up together and finally fully expand, and the upper end of the scraping member 3433 is exactly clamped in the groove. If the width of the groove is greater than the width of the scraping member 3433, then start the electric push rod 345 to finally adjust the size of the scraping member 3433 to ensure that the scraping member 3433 contacts the inner side wall of the groove. After that, control the traction sheave 7 to rotate so that the groove contacts the scraping member 3433, and the dirt in the groove can be scraped off. After the dirt is cleaned, control the traction sheave 7 to stop rotating and start using the detection component 35 to detect the groove;

[0038] Step 4: Press down the pressing member 381, so that the pressing member 381 drives the clamping shaft 382 to separate from the clamping hole 37. Then, rotate the rotating member 32, which can drive the rotating member 33, the detection component 35 and the scraping component to rotate together. When the rotating member 33 rotates 180 degrees, stop pressing the pressing member 381. Under the elastic force of the supporting spring 383, the pressing member 381 and the clamping shaft 382 move up synchronously, and finally the clamping shaft 382 is clamped with the clamping hole 37 above it, so that the position of the rotating member 33 is locked. At this time, the detection head also just contacts the groove. Control the traction sheave 7 to start again to detect the wear degree of the groove of the traction sheave 7. After the detection is completed, disassemble the detection device and observe the data recorded by the detection component 35 to judge the wear condition of the traction sheave 7.
