Abstract
Description
Technical Field
[0001] This invention relates to the field of elevator equipment cleaning and maintenance technology, and in particular to a cleaning device for traction sheaves of traction elevators. Background Technology
[0002] The traction sheave and traction rope are the core transmission components of a traction elevator, directly determining the elevator's stability and safety. During long-term service, the annular groove of the traction sheave and the surface of the traction rope are continuously exposed to environmental contaminants such as dust and fine debris. Currently, most traction elevators on the market only have basic transmission functions in their traction rope sheave structure and lack a corresponding automated cleaning system. Daily cleaning largely relies on maintenance personnel periodically stopping the elevator for manual wiping and cleaning. Only a few elevators are equipped with simple cleaning accessories, and these accessories are structurally limited, only capable of simple dust removal for single areas and unable to meet the overall cleaning and maintenance needs of the traction rope sheave.
[0003] Existing cleaning methods have several significant drawbacks. Manual cleaning during downtime consumes elevator operating time, impacting efficiency. Furthermore, manual cleaning suffers from uneven coverage and insufficient cleaning force, failing to thoroughly remove stubborn impurities from crevices and grooves. Conventional, simple cleaning accessories lack the ability to simultaneously clean the traction sheave and traction rope, and these components lack self-cleaning capabilities, leading to impurity accumulation and reduced cleaning effectiveness over time. Moreover, the generated impurities cannot be collected and easily flow back into the equipment, accelerating wear on traction components, causing transmission jams, abnormal noises, and significantly shortening equipment lifespan, thus reducing elevator safety and stability. Therefore, we propose a traction rope sheave cleaning device for traction elevators to address this problem. Summary of the Invention
[0004] The purpose of this invention is to provide a traction rope sheave cleaning device for traction elevators, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A traction sheave cleaning device for a traction elevator includes a traction mechanism and a cleaning mechanism. The traction mechanism includes a base, a traction sheave, a traction rope, a drive motor, and a reducer. An installation shaft is fixedly installed inside the traction sheave. Fixing frames are fixedly installed on both the front and rear sides of the top of the base. The installation shaft is rotatably installed in the two fixing frames. The cleaning mechanism includes: a rotating shaft, multiple brush plates, a vertical shaft, a movable frame, and two mounting plates. Brush plates are fixedly installed on both sides of the movable frame. Cleaning brushes are fixedly installed on the outer side of the brush plates. A fixing rod is fixedly installed on the top of the brush plates, and a scraper is fixedly installed on the top of the fixing rod.
[0006] Preferably, the rotating shaft is rotatably mounted in two mounting plates, the mounting plates are fixedly mounted in corresponding fixing frames, a driving bevel gear is fixedly mounted at the rear end of the rotating shaft, and a driven bevel gear is fixedly mounted at the top end of the vertical shaft, the driven bevel gear meshing with the driving bevel gear; A rotating arm is fixedly installed at the bottom of the vertical shaft, a round rod is fixedly installed at one end of the rotating arm, a round shaft is fixedly installed at the bottom of the movable frame, and the same linkage plate is rotatably sleeved on the outer side of the round shaft and the round rod.
[0007] Preferably, a brush is fixedly installed on the outer side of the brush disc, the brush disc is fixedly sleeved on the outer side of the rotating shaft, a driven pulley is fixedly installed at the front end of the rotating shaft, a driving pulley is fixedly installed at the front end of the mounting shaft, and the same belt is driven and installed on the driving pulley and the driven pulley.
[0008] Preferably, the outer side of the traction sheave is provided with multiple annular grooves, the traction rope is wound around the corresponding annular groove, the brush abuts against the corresponding annular groove, the rear end of the mounting shaft is connected to the output end of the reducer, the drive motor is fixedly mounted on the top of the base, and the output end of the drive motor is connected to the input end of the reducer.
[0009] Preferably, two support plates are fixedly installed on the top of the base, the same collection frame is fixedly installed on the top of the two support plates, a crossbeam is fixedly installed between the two support plates, and the movable frame is slidably sleeved on the outside of the crossbeam.
[0010] Preferably, a mounting frame is fixedly installed on the rear side of the collection frame, the vertical shaft is rotatably installed in the mounting frame, and a limit ring is fixedly sleeved on the outer side of the vertical shaft, with the limit ring abutting against the mounting frame.
[0011] The beneficial effects of this invention are as follows: 1. The traction sheave cleaning device for traction elevators described in this invention completes the cleaning operation by relying on the power of the elevator's existing traction mechanism. The device does not require a separate drive power source; it drives the entire cleaning structure synchronously through the belt drive and bevel gear drive during the traction sheave's operation. This power linkage method enables the cleaning operation to be carried out simultaneously with the elevator traction work, eliminating the need for manual operation to start and stop the cleaning equipment. This effectively simplifies the overall structure of the device, reduces equipment modification and production costs, and avoids energy consumption and potential malfunctions caused by operating additional power equipment. It is suitable for the installation and use requirements of conventional traction elevators and can continuously carry out cleaning operations while the elevator is operating normally without interfering with the elevator's regular operation.
[0012] 2. The traction sheave cleaning device for traction elevators described in this invention employs a dual cleaning structure combining a rotating brush and a reciprocating cleaning brush. This allows for targeted cleaning of the annular groove of the traction sheave and the traction rope. The rotating brush penetrates deep into the annular groove of the traction sheave to remove accumulated impurities, while the reciprocating cleaning brush thoroughly wipes away dirt adhering to the surface of the traction rope, overcoming the limited cleaning range of a single cleaning structure. This comprehensive cleaning method effectively removes impurities from critical parts of the traction transmission, preventing impurities from accumulating in the gaps of the transmission structure and ensuring the transmission accuracy between the traction sheave and the traction rope, thus maintaining the stable transmission state of the elevator traction system.
[0013] 3. The traction rope sheave cleaning device for traction elevators described in this invention, by incorporating a scraper structure into the cleaning mechanism, can simultaneously perform self-cleaning during the reciprocating cleaning operation of the cleaning brush. After the cleaning brush continuously cleans the components, dust and debris will adhere to the surface. The scraper moves synchronously with the cleaning brush, continuously scraping away various impurities adhering to the surface of the cleaning brush, preventing the accumulation of impurities that clog the gaps in the cleaning brush and thus reduce cleaning performance. This self-cleaning structure eliminates the need for regular manual cleaning and maintenance of the cleaning components, ensuring that the cleaning brush always maintains a good cleaning condition, guaranteeing the stability of the cleaning effect during long-term continuous operation of the device, and significantly reducing the workload and frequency of daily equipment maintenance.
[0014] 4. The traction sheave cleaning device for traction elevators described in this invention, by configuring a dedicated collection frame structure at the bottom of the device, can centrally collect dust and debris that falls off during the cleaning process. Debris falling from the traction sheave, traction rope, and cleaning brush during cleaning can fall directly into the collection frame, preventing cleaning debris from randomly scattering into the elevator equipment or machine room floor. This not only keeps the environment around the elevator traction equipment clean and prevents scattered debris from re-adhering to the surface of the traction drive components and causing secondary pollution, but also facilitates unified cleaning by staff, further improving the convenience of equipment operation and maintenance.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0018] Reference Figures 1-10A traction sheave cleaning device for traction elevators includes a traction mechanism and a cleaning mechanism 7. The traction mechanism includes a base 1, a traction sheave 4, a traction rope 12, a drive motor 6, and a reducer 5. An installation shaft 3 is fixedly installed inside the traction sheave 4. Fixing brackets 2 are fixedly installed on both the front and rear sides of the top of the base 1. The installation shaft 3 is rotatably installed within the two fixing brackets 2. The base 1 is integrally cast from high-strength carbon steel, resulting in high overall structural strength, excellent load-bearing capacity, and resistance to deformation. It provides a stable mounting foundation for all components of the device and buffers mechanical vibrations generated during equipment operation, improving the overall operational stability of the equipment. The fixing brackets 2 are formed by bending thickened stainless steel plates, possessing good corrosion resistance and structural rigidity. They are not easily rusted or deformed in the elevator machine room environment and provide precise and stable rotational support points for the installation shaft 3, ensuring the installation accuracy of the traction drive structure.
[0019] The cleaning mechanism 7 includes: a rotating shaft 702, multiple brush plates 703, a vertical shaft 707, a movable frame 712, and two mounting plates 701. Brush plates 713 are fixedly mounted on both sides of the movable frame 712. Cleaning brushes 714 are fixedly mounted on the outer side of each brush plate 713. A fixing rod 715 is fixedly mounted on the top of each brush plate 713, and a scraper 716 is fixedly mounted on the top of the fixing rod 715. The cleaning mechanism 7 is integrated with the traction mechanism, exhibiting strong structural integration and requiring no separate machine room installation space, making it suitable for retrofitting existing traction elevators. The mounting plates 701 are made of hard alloy sheet, ensuring a stable structure that is not easily deformed, and providing high installation positioning accuracy. This effectively guarantees the coaxiality of the rotating shaft 702 during rotation, preventing rotational deviation and jamming. The movable frame 712 is made of lightweight, high-strength aluminum alloy, resulting in low weight, low sliding resistance, and excellent structural toughness, allowing for long-term reciprocating sliding without damage. The brush plate 713 is integrally molded from high-strength insulating engineering plastic, making it hard and preventing wear on the elevator's metal components. It can stably bear the working load of the cleaning brush 714 and scraper 716. The cleaning brush 714 is made of high-elasticity, wear-resistant nylon fiber, with fine and soft fibers that provide uniform cleaning coverage. It effectively removes dust and debris from the surface of components while avoiding scratches on the surface structure of the traction rope 12. The fixing rod 715 is made of solid round steel, providing sufficient rigidity and strong bending resistance. It can stably support the scraper 716 for a long time, ensuring that the scraper 716 does not shift its working position. The scraper 716 is made of wear-resistant polyurethane, with a flat and wear-resistant scraping end face. It has good scraping effect and a long service life, and can stably complete the self-cleaning operation of the cleaning brush 714.
[0020] In this embodiment, the rotating shaft 702 is rotatably mounted within two mounting plates 701, which are fixedly mounted within corresponding mounting brackets 2. A driving bevel gear 705 is fixedly mounted at the rear end of the rotating shaft 702, and a driven bevel gear 706 is fixedly mounted at the top end of the vertical shaft 707. The driven bevel gear 706 meshes with the driving bevel gear 705. The rotating shaft 702 is made of precision-polished round steel, with a high surface smoothness and low rotational friction resistance, reducing power transmission loss and ensuring smooth and stable rotation. Both the driving bevel gear 705 and the driven bevel gear 706 are made of quenched alloy steel, hardened, with high surface hardness and excellent wear resistance. They exhibit high gear meshing precision and small transmission clearance, enabling precise power reversal and stable transmission, ensuring the synchronization of the various components of the cleaning mechanism, and avoiding problems such as transmission lag and asynchronous operation.
[0021] A rotating arm 708 is fixedly mounted at the bottom of the vertical shaft 707, and a round rod 709 is fixedly mounted at one end of the rotating arm 708. A round shaft 711 is fixedly mounted at the bottom of the moving frame 712. The outer sides of the round shaft 711 and the round rod 709 are rotatably connected to the same linkage plate 710. The vertical shaft 707 is made of tempered alloy steel, which has high torsional strength and can withstand continuous rotational loads for a long time without deformation or breakage, ensuring continuous and stable power output. The rotating arm 708 is formed by one-piece forging, with no splicing gaps in the overall structure, uniform force distribution, and high structural strength, which can stably drive the round rod 709 to perform circular motion. The surfaces of the round rod 709 and the round shaft 711 are polished and rust-proofed, resulting in high smoothness of rotation and resistance to rust and jamming. The linkage plate 710 is made of high-toughness engineering plastic material, which is wear-resistant and impact-resistant. It can stably connect the power of the round rod 709 and the round shaft 711, accurately converting the circular motion of the rotating arm 708 into the linear reciprocating motion of the moving frame 712. The transmission is stable and not prone to failure.
[0022] In this embodiment, a brush 704 is fixedly installed on the outer side of the brush disc 703. The brush disc 703 is fixedly sleeved on the outer side of the rotating shaft 702. A driven pulley 9 is fixedly installed at the front end of the rotating shaft 702, and a driving pulley 10 is fixedly installed at the front end of the mounting shaft 3. The same belt 11 is driven and installed on the driving pulley 10 and the driven pulley 9. The brush disc 703 is made of hard flame-retardant plastic material, which is lightweight and has good structural stability. It does not shake or deviate during the rotation of the rotating shaft 702 and can stably drive the brush 704 to rotate synchronously. The brush 704 is made of high-density wear-resistant polypropylene fiber material. The fiber is uniform in thickness and has strong toughness, which can penetrate into the annular groove of the traction wheel 4 to thoroughly clean the hidden impurities and dirt. Both the driving pulley 10 and the driven pulley 9 are made of lightweight aluminum alloy material, which has high structural strength and high transmission accuracy. The surface of the wheel body is treated with anti-slip treatment to effectively prevent the belt 11 from slipping and falling off. The belt 11 is made of high-strength rubber transmission belt, which has small tensile deformation, strong elasticity and adaptability, and high transmission efficiency. It can realize the synchronous and uninterrupted transmission of power from the traction mechanism to the cleaning mechanism without the need for an additional power source.
[0023] In this embodiment, the traction sheave 4 has multiple annular grooves on its outer side. The traction rope 12 is wound around the corresponding annular groove, and the brush 704 abuts against the corresponding annular groove. The rear end of the mounting shaft 3 is connected to the output end of the reducer 5. The drive motor 6 is fixedly mounted on the top of the base 1, and the output end of the drive motor 6 is connected to the input end of the reducer 5. The traction sheave 4 is made of alloy cast steel, which has excellent wear resistance and pressure resistance, and a stable overall structure. The outer annular grooves are precision milled, with regular and smooth dimensions, which can precisely match the traction rope 12 to ensure the stability of the elevator traction transmission. The reducer 5 can reduce the output speed of the drive motor 6 and increase the torque, thereby reducing the rotation speed of the mounting shaft 3, improving rotational stability, adapting to the smooth operation requirements of the elevator, and providing stable transmission power for the cleaning mechanism. The drive motor 6 operates stably and has uniform power output, which can simultaneously meet the power requirements of elevator traction transmission and equipment cleaning operations. The brush 704 is always positioned in close contact with the annular grooves, and can perform dynamic cleaning operations inside the annular grooves in all directions without dead angles during the continuous rotation of the traction sheave 4.
[0024] In this embodiment, two support plates 801 are fixedly installed on the top of the base 1, and the same collection frame 8 is fixedly installed on the top of the two support plates 801. A crossbeam 802 is fixedly installed between the two support plates 801, and the movable frame 712 is slidably sleeved on the outside of the crossbeam 802. The support plates 801 are made of stainless steel, which is corrosion-resistant and has a strong load-bearing capacity, and can stably support the collection frame 8 and the crossbeam 802, ensuring the installation stability of the overall cleaning auxiliary structure. The collection frame 8 is made of rust-proof thin steel plate bent and welded, with a regular and solid structure, which can centrally collect dust, debris and impurities that fall off during cleaning operations, avoiding secondary pollution of equipment and a dirty machine room environment caused by the scattering of impurities. The crossbeam 802 is made of solid polished round steel, with a smooth and wear-resistant surface, which can significantly reduce the frictional resistance of the reciprocating sliding of the movable frame 712, ensuring that the movable frame 712 slides smoothly and stably without jamming or abnormal noise, and improving the stability of reciprocating cleaning operations.
[0025] In this embodiment, a mounting frame 14 is fixedly installed on the rear side of the collection frame 8. The vertical shaft 707 is rotatably installed inside the mounting frame 14, and a limit ring 13 is fixedly sleeved on the outer side of the vertical shaft 707, with the limit ring 13 abutting against the mounting frame 14. The mounting frame 14 is made of thickened steel plate welded together, with strong structural stability. It can provide an independent and stable rotation mounting point for the vertical shaft 707, limiting the lateral sway of the vertical shaft 707 and ensuring the stability of the transmission structure. The limit ring 13 is made of high wear-resistant copper sleeve material, with excellent wear resistance and low friction coefficient. It can form an axial limit on the vertical shaft 707, effectively preventing the vertical shaft 707 from moving up and down during rotation, improving the rotation accuracy of the vertical shaft 707, ensuring the operational accuracy of the overall linkage transmission structure, and extending the service life of the equipment.
[0026] In this embodiment, during use, the drive motor 6 mounted on the top of the base 1 outputs power to the reducer 5. The reducer 5 drives the mounting shaft 3 to rotate. The mounting shaft 3 rotates stably inside the two fixed frames 2 and drives the traction wheel 4 to rotate synchronously, realizing the basic transmission work of the elevator traction mechanism. During the rotation of the mounting shaft 3, it drives the front fixed drive pulley 10 to rotate synchronously. The drive pulley 10 drives the driven pulley 9 to rotate through the belt 11. The driven pulley 9 drives the rotating shaft 702 to rotate inside the two mounting plates 701. The rotating shaft 702 drives the multiple brush discs 703 fixedly sleeved on the outside and the brushes 704 fixed on the outside of the brush discs 703 to rotate synchronously, so that the brushes 704 fit into the annular groove on the outside of the traction wheel 4 to perform cleaning work, thereby removing the traction wheel 4. Dust and debris accumulated inside the annular groove of wheel 4 are removed, ensuring the groove of traction wheel 4 is clean and free of debris. While the rotating shaft 702 rotates, the driving bevel gear 705 fixed at its rear end rotates synchronously. The driving bevel gear 705 meshes with and drives the driven bevel gear 706 to rotate, thereby driving the vertical shaft 707 to rotate. The vertical shaft 707 completes stable rotation inside the mounting frame 14. The limiting ring 13 fixedly sleeved on the outside of the vertical shaft 707 fits against the mounting frame 14 for limiting, effectively ensuring the stability and accuracy of the vertical shaft 707 during rotation. The rotating arm 708 fixed at the bottom of the vertical shaft 707 rotates synchronously with the vertical shaft 707. The rotating arm 708, through the round rod 709 fixed at its end, works in conjunction with the linkage plate 710 and the round shaft 711 fixed at the bottom of the moving frame 712 to form a linkage transmission. The structure drives the movable frame 712 to slide back and forth on the outside of the crossbeam 802 between the two support plates 801. During the continuous reciprocating movement of the movable frame 712, it drives the brush plates 713 fixed on both sides and the cleaning brushes 714 fixed on the outside of the brush plates 713 to move back and forth synchronously, performing a full-range reciprocating cleaning operation on the traction rope 12 wound inside the corresponding annular groove of the traction wheel 4, thoroughly removing dirt and impurities attached to the surface of the traction rope 12. At the same time, the movable frame 712 drives the scraper 716 to move back and forth synchronously through the fixed rod 715 fixed on the top of the brush plate 713, continuously scraping and cleaning the surface of the cleaning brush 714 after the cleaning work is completed, timely removing dust and debris adhering to the surface of the cleaning brush 714, and preventing the accumulation of impurities on the cleaning brush 714 from affecting the cleaning. The cleaning effect is excellent. All debris and debris removed from the traction sheave 4, traction rope 12, and cleaning brush 714 will naturally fall into the collection frame 8 fixed at the top of the two support plates 801 for centralized collection and storage. This device relies entirely on the running power of the traction mechanism to drive the cleaning mechanism 7, without the need for additional drive equipment. It can simultaneously complete multiple tasks such as cleaning the groove of the traction sheave 4, cleaning the traction rope 12, self-cleaning of the cleaning brush 714, and centralized collection of debris. It can continuously maintain the cleanliness of the traction rope 12 sheave and traction rope 12, effectively avoiding problems such as traction transmission jamming and accelerated wear caused by the accumulation of debris, and stably ensuring the operating accuracy and safety of the traction elevator traction system. At the same time, the cleaning brush 714 has a real-time self-cleaning operation mode.To ensure the equipment maintains excellent cleaning performance over the long term.
