Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of elevator inspection, in particular to an elevator traction wheel rope groove wear inspection device. Background Art
[0002] The traction sheave is the rope sheave on the traction machine, also called the traction rope sheave or driving rope sheave; it is the device for transmitting traction power in the elevator, and it transmits power by the friction between the traction wire rope and the rope groove on the traction wheel rim. After the traction sheave is used for a long time, its wheel groove will be worn. When the wear reaches a certain range, the traction sheave needs to be replaced to avoid elevator accidents. However, the existing technology for detecting the wear of the traction sheave has the following shortcomings:
[0003] Manual inspection of the wear of the traction sheave is a traditional method, and its shortcomings are as follows: Subjectivity: Manual inspection is affected by the subjective judgment and experience of the inspector, and the inspection results may be inaccurate and inconsistent; Time-consuming: Manual inspection takes a long time, especially in the case of large elevators, which requires more time and manpower; Inaccuracy: Manual inspection may miss some minor wear, which may have a negative impact on the safety and performance of the traction sheave;
[0004] In addition, when dust and dirt fall on the traction sheave, the following problems will occur: Reduced traction: If a lot of dust and dirt accumulate on the traction sheave, its friction will be reduced, resulting in reduced traction of the elevator, thus affecting the operating efficiency of the elevator; Increased wear: When there is dust and dirt on the traction sheave, the friction between the traction sheave and the wire rope will increase when the elevator is running, causing the traction sheave to wear more severely, thereby shortening the life of the elevator traction sheave and wire rope; Reduced safety: If the traction sheave is covered with a lot of dust and dirt, the friction between the traction sheave and the wire rope will be reduced, which may cause the traction sheave to slide or slip when the elevator goes up or down, thereby increasing the risk and safety hazards of the elevator;
[0005] Therefore, dust and dirt falling into the elevator traction sheave need to be cleaned in time to ensure accurate detection of the wear of the traction rope groove, thereby ensuring the normal operation and safety of the elevator. Utility Model Content

DETAILED DESCRIPTION
[0025] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0026] like Figures 1 to 4 As shown, an elevator traction wheel rope groove wear inspection device described in the utility model includes a mounting bracket 1, a traction wheel 2, a supporting base plate 3, a cleaning component 4 and a detection component 5. The traction wheel 2 and the supporting base plate 3 are fixedly mounted on the mounting bracket 1, and the supporting base plate 3 is located below the traction wheel 2. The traction wheel 2 is provided with a plurality of traction rope grooves. The cleaning component 4 and the detection component 5 are fixedly mounted on the top of the supporting base plate 3. The cleaning component 4 is used to clean the traction rope groove before detection, and the detection component 5 is used to measure the wear of the traction rope groove.
[0027] The utility model cleans the traction rope groove before detection through the cleaning component 4, which can not only improve the accuracy of wear detection, but also ensure that each detection is carried out in a clean environment, thereby improving the reliability of the result. At the same time, regular and effective cleaning of the traction rope groove can reduce the additional wear of foreign matter on the surface of the traction sheave 2, which helps to extend the service life of the traction sheave 2 and improve the detection efficiency.
[0028] Specifically, refer to Figure 2 and Figure 3 As shown, the cleaning assembly 4 includes a limit bracket 4a and a movable scraper 4b, wherein the limit bracket 4a is arranged on the top of the supporting base plate 3, and the movable scraper 4b is movably arranged on the limit bracket 4a. The movable scraper 4b is used to scrape off dirt, dust and other impurities in the traction rope groove. The movable scraper 4b can be made of a wear-resistant material with moderate hardness to ensure that it can effectively clean the rope groove and is not easy to wear. At the same time, the movable cooperation between the limit bracket 4a and the movable scraper 4b enables the movable scraper 4b to contact the traction rope groove only when scraping and cleaning the traction rope groove, thereby avoiding unnecessary wear and friction, reducing the additional wear of foreign matter on the surface of the traction wheel 2, and helping to extend the service life of the traction wheel 2.
[0029] Specifically, refer to Figure 2 and Figure 3As shown, the top of the limit bracket 4a is provided with a plug block 4a1 in a vertical state, and the bottom of the movable scraper block 4b is provided with a slot 4b1 for the plug block 4a1 to be inserted, and the plug block 4a1 and the slot 4b1 are in sliding contact and cooperation. The connection structure between the limit bracket 4a and the movable scraper block 4b realizes the stable movement of the movable scraper block 4b during the cleaning process through the sliding contact and cooperation between the plug block 4a1 and the slot 4b1, ensuring the effective cleaning of the traction rope groove. It not only improves the cleaning efficiency, but also helps to extend the service life of the equipment.
[0030] Specifically, refer to Figure 2 and Figure 3 As shown, the top of the plug block 4a1 is provided with a first extension portion 4a2 extending outward, and the notch of the slot 4b1 is provided with a second extension portion 4b2 extending inward. When the plug block 4a1 is pulled out of the slot 4b1, the first extension portion 4a2 contacts the second extension portion 4b2. When the plug block 4a1 is pulled out of the slot 4b1, the contact between the first extension portion 4a2 and the second extension portion 4b2 indicates that the plug block 4a1 has reached its maximum pull-out position. This helps to ensure that the plug block 4a1 will not accidentally completely detach from the slot 4b1, thereby maintaining a stable connection between the movable scraper block 4b and the limiting bracket 4a, thereby enhancing the stability between the movable scraper block 4b and the limiting bracket 4a, thereby improving the reliability and efficiency of the entire cleaning assembly 4.
[0031] Specifically, refer to Figure 2 and Figure 3 As shown, the cleaning component 4 also includes a telescopic motor 4c, which is fixedly mounted on the limit bracket 4a in a vertical state, and the output end of the telescopic motor 4c is fixedly connected to the movable scraper block 4b. During the cleaning process, the telescopic motor 4c is started and drives its output end to extend outward. Since the output end is fixedly connected to the movable scraper block 4b, the movable scraper block 4b will move upward accordingly to scrape and clean the contour of the traction rope groove. When the cleaning is completed, the telescopic motor 4c is started and drives its output end to retract. Since the output end of the telescopic motor 4c is fixedly connected to the movable scraper block 4b, the movable scraper block 4b will move downward accordingly, away from the contour of the traction rope groove, avoiding unnecessary wear and friction, and reducing the additional wear of foreign matter on the surface of the traction wheel 2, which helps to extend the service life of the traction wheel 2.
[0032] Specifically, refer to Figure 2 and Figure 3As shown, the cleaning assembly 4 also includes a spring 4d, a socket is provided at the bottom of the movable scraper block 4b, the output end of the telescopic motor 4c can be movably inserted into the socket, and the spring 4d is arranged between the output end of the telescopic motor 4c and the bottom of the socket. The adaptability and stability of the cleaning assembly 4 are improved by the spring 4d. The buffering and supporting effects of the spring 4d help to reduce the vibration and impact of the movable scraper block 4b during movement, thereby protecting the traction rope groove from potential damage. At the same time, the elastic support of the spring 4d enables the movable scraper block 4b to fit the shape of the traction rope groove more closely, thereby improving the uniformity and efficiency of cleaning.
[0033] Specifically, refer to Figure 2 and Figure 3 As shown, the cleaning assembly 4 further includes a dust-free cloth strip 4e, which is detachably arranged on the top of the movable scraper block 4b. By introducing the dust-free cloth strip 4e as a material for directly contacting and cleaning the traction rope groove, the cleaning effect and safety of the cleaning assembly 4 are significantly improved. The dust-free property, softness, durability and detachable design of the dust-free cloth strip 4e enable it to effectively scrape off dirt, protect the traction rope groove and facilitate replacement and cleaning.
[0034] Specifically, refer to Figure 4 As shown, the detection assembly 5 includes a fixed bracket 5a, a detection sensor 5b and a control terminal. The fixed bracket 5a is arranged on the top of the supporting base plate 3, and the detection sensor 5b is arranged on the fixed bracket 5a and is located below the traction rope groove. The control terminal and the detection sensor 5b are electrically connected. The function of the fixed bracket 5a is to stably support the detection sensor 5b and ensure that it will not move or tilt due to external factors during operation, thereby ensuring the accuracy of the detection result. When the traction wheel 2 rotates, the traction rope groove will pass under the detection sensor 5b. At this time, the detection sensor 5b will send a signal (such as a laser beam or light) and contact the bottom of the traction rope groove. By measuring the difference between the emitted signal and the received signal, the depth, width or other related parameters of the traction rope groove can be obtained, and then the wear amount of the traction rope groove can be calculated through the control terminal.
