Description

Technical Field

[0001] This utility model belongs to the field of elevator cleaning technology, specifically relating to an automatic cleaning device for elevator hall door guide rails. Background Technology

[0002] During elevator operation, cleaning and maintaining the guide rails is crucial for ensuring smooth operation of the landing doors. However, dust, hair, and other debris in the air can easily enter the guide rails as the landing doors open and close, while debris from within the elevator shaft can also seep into the guide rail area through gaps. Over time, this accumulation of debris increases the frictional resistance between the landing doors and the guide rails, leading to problems such as door jamming, abnormal noises, and affecting the passenger experience. It can even cause malfunctions such as incomplete door closure or deviation from the elevator's trajectory.

[0003] Currently, cleaning elevator hall door guide rails mainly relies on manual operation. Maintenance personnel must use brushes, cloths, or vacuum cleaners to clean each guide rail individually while the elevator is stopped. This method is inefficient, especially in high-rise buildings or scenarios with multiple elevators, where cleaning requires a significant amount of manpower and time. Furthermore, manual cleaning necessitates frequent elevator starts and stops, impacting normal elevator operation. Therefore, a device capable of automatically cleaning elevator hall door guide rails is needed to improve cleaning efficiency and quality, meeting the demands of efficient elevator operation and maintenance in modern buildings. Utility Model Content

[0004] To overcome the problems of low efficiency, high manpower and time consumption, and frequent elevator start-stop operations affecting normal use caused by manual cleaning of elevator hall door guide rails in the prior art, this utility model provides an automatic cleaning device for elevator hall door guide rails. Through the cooperation of an eccentric disc and a connecting rod structure, the linear motion of the hall door mounting plate along the guide rail is converted into the high-frequency reciprocating motion of the cleaning brush. Combined with adjustable elastic components and a quick-release cleaning plate structure, a highly efficient cleaning mechanism for the guide rail surface is formed, significantly improving the cleaning effect and reducing maintenance costs.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: An automatic cleaning device for elevator hall door guide rails mainly includes a hall door mounting plate, a guide rail, a landing door back plate, an adjustment component, and a cleaning component. The landing door back plate is fixedly installed with the guide rail along its length. A roller is provided on the side of the hall door mounting plate near the landing door back plate. The hall door mounting plate is hooked onto the guide rail via the roller and can move along the guide rail. The cleaning component is installed on the hall door mounting plate and moves synchronously with the hall door mounting plate along the guide rail. The cleaning component includes a support plate, an eccentric disc, a connecting rod, a slider, an L-shaped connecting plate, and a cleaning plate. The end of the support plate is fixed to the end of the hall door mounting plate with bolts. A guide groove is provided on the support plate, and a slider is slidably connected within the guide groove, allowing the slider to perform linear reciprocating motion within the guide groove. The eccentric disc is located on the side of the hall door mounting plate opposite to the landing door back plate and is coaxially connected to the roller via a connecting shaft passing through the hall door mounting plate. The connecting shaft can rotate synchronously with the roller. One end of the connecting rod is hinged to the side of the eccentric disk via a hinge pin, and the other end is hinged to the side of the slider via a hinge pin, thereby converting the rotational motion of the eccentric disk into the linear reciprocating motion of the slider. An L-shaped connecting plate is bolted to the side of the slider near the back panel of the landing door. The cleaning plate is installed at the bottom of the L-shaped connecting plate via an adjustment assembly. The lower surface of the cleaning plate has bristles evenly distributed to contact the top and sides of the guide rail.

[0006] The adjustment assembly includes a horizontal connecting plate, guide rods, and springs. Two guide rods are vertically welded to the top surface of the horizontal connecting plate. The top ends of the guide rods pass through guide holes in the L-shaped connecting plate and are fixed with nuts. Springs are sleeved on the guide rods, with their bottom ends pressing against the top surface of the horizontal connecting plate and their top ends pressing against the bottom surface of the L-shaped connecting plate, so that the cleaning plate always fits tightly against the guide rail surface under the elastic force of the springs.

[0007] The cleaning plate is mounted on the L-shaped connecting plate via a quick-release structure. The quick-release structure includes a trapezoidal slot at the bottom of the horizontal connecting plate and a trapezoidal block on the top surface of the cleaning plate, the trapezoidal block fitting into the trapezoidal slot. During installation or removal, the trapezoidal block on the cleaning plate is pushed in or pulled out along the trapezoidal slot, facilitating quick replacement of the cleaning plate.

[0008] The bristles are made of nylon or polyester and their ends are rounded to reduce scratch damage to the guide rail surface and improve cleaning performance.

[0009] The beneficial effects of this utility model are: This invention utilizes the cooperation of an eccentric disc and a connecting rod to transform the linear motion of the hall door hanging plate along the guide rail into the high-frequency reciprocating motion of the cleaning plate. The bristles on the cleaning plate can repeatedly scrub the surface and sides of the guide rail, effectively removing dust, hair, and other debris, thus achieving automated cleaning of the guide rail without manual intervention. This reduces labor costs and time consumption, and improves cleaning efficiency and quality. The spring in the adjusting component ensures that the cleaning plate maintains good contact with the guide rail under different working conditions, preventing a decrease in cleaning effect due to loosening. The quick-release structure makes it easy to replace the cleaning plate, reducing maintenance time and costs. Attached Figure Description

[0016] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0017] This utility model discloses an automatic cleaning device for elevator hall door guide rails, mainly including a hall door mounting plate 1, a guide rail 2, a landing door back panel 3, an adjustment component 4, and a cleaning component 5. The landing door back panel 3 is the basic support part of the entire device, and the guide rail 2 is fixedly installed on it along its length. The guide rail 2 is used to guide the movement of the hall door mounting plate 1 and also serves as the target object for cleaning. A roller 6 is provided on the side of the hall door mounting plate 1 near the landing door back panel 3. The roller 6 contacts the guide rail 2 and can roll along the guide rail 2, allowing the hall door mounting plate 1 to move linearly along the guide rail 2. The cleaning component 5 is installed on the other side of the hall door mounting plate 1. The cleaning component 5 moves synchronously with the hall door mounting plate 1 and completes the cleaning of the surface and sides of the guide rail 2 during the movement.

[0018] The cleaning assembly 5 includes a support plate 7, an eccentric disc 8, a connecting rod 9, a slider 10, an L-shaped connecting plate 11, and a cleaning plate 12. The support plate 7 is fixed to the end of the hall door hanging plate 1 by bolts and has a guide groove 13. The slider 10 is slidably connected in the guide groove 13 and can make linear reciprocating motion within the guide groove 13. The eccentric disc 8 is located on the side of the hall door hanging plate 1 away from the landing door back panel 3 and is coaxially connected to the hanging wheel 6 through a connecting shaft 14 that passes through the hall door hanging plate 1. The connecting shaft 14 can rotate synchronously with the hanging wheel 6. One end of the connecting rod 9 is hinged to the side of the eccentric disc 8 by a hinge pin, and the other end is hinged to the side of the slider 10 by a hinge pin, so that the rotational motion of the eccentric disc 8 is converted into the linear reciprocating motion of the slider 10.

[0019] An L-shaped connecting plate 11 is bolted to the side of the slider 10 near the back panel 3 of the door. A cleaning plate 12 is mounted on the bottom of the L-shaped connecting plate 11 via an adjusting assembly 4. The lower surface of the cleaning plate 12 is evenly covered with bristles 15, which can contact the top and sides of the guide rail 2. When the slider 10 reciprocates linearly within the guide groove 13, the cleaning plate 12 generates a high-frequency reciprocating motion, causing the bristles 15 to repeatedly scrub the surface and sides of the guide rail 2.

[0020] The adjusting assembly 4 includes a horizontal connecting plate 16, guide rods 17, and springs 18. Two guide rods 17 are vertically welded to the top surface of the horizontal connecting plate 16. The top ends of the guide rods 17 pass through guide holes on the L-shaped connecting plate 11 and are fixed by nuts 20. Springs 18 are sleeved on the guide rods 17, with their bottom ends abutting against the top surface of the horizontal connecting plate 16 and their top ends abutting against the bottom surface of the L-shaped connecting plate 11. The cleaning plate 12 can maintain good contact with the guide rail 2 under the elastic force of the springs 18, avoiding a decrease in cleaning effect due to loosening.

[0021] The cleaning plate 12 is mounted on the L-shaped connecting plate 11 via a quick-release structure, which includes a trapezoidal slot 19 and a trapezoidal block 20. The trapezoidal slot 19 is located at the bottom of the horizontal connecting plate 16, and the trapezoidal block 20 is located on the top surface of the cleaning plate 12; the two fit together. During installation, the trapezoidal block 20 on the cleaning plate 12 is pushed in along the direction of the trapezoidal slot 19 to secure it. During disassembly, the trapezoidal block 20 is simply pulled out of the trapezoidal slot 19. This quick-release structure makes the replacement of the cleaning plate 12 more convenient, reducing maintenance time and costs.

[0022] The bristles 15 are made of nylon or polyester, with rounded ends. This material selection and end treatment improve cleaning efficiency while reducing scratch damage to the surface of the guide rail 2. The distribution density of the bristles 15 on the lower surface of the cleaning plate 12 is optimized to ensure complete coverage of the top and sides of the guide rail 2, thereby achieving efficient cleaning.

[0023] The specific operation process of this device is as follows: When the elevator hall door opens or closes, the hall door mounting plate 1 moves along the guide rail 2 via the hanging wheel 6. The rotation of the hanging wheel 6 drives the connecting shaft 14 to rotate synchronously, thereby driving the eccentric disk 8 to rotate. The rotational motion of the eccentric disk 8 is transmitted to the slider 10 through the connecting rod 9, causing the slider 10 to perform linear reciprocating motion within the guide groove 13. The motion of the slider 10 is transmitted to the cleaning plate 12 through the L-shaped connecting plate 11, causing the cleaning plate 12 to generate high-frequency reciprocating motion. During this process, the bristles 15 on the lower surface of the cleaning plate 12 repeatedly brush the top and sides of the guide rail 2, effectively removing dust, hair, and other debris. The spring 18 in the adjusting assembly 4 ensures that the cleaning plate 12 is always in close contact with the surface of the guide rail 2, thereby ensuring the stability of the cleaning effect.

[0024] Furthermore, the quick-release structure of the cleaning plate 12 allows for rapid replacement of the cleaning plate 12 when the bristles 15 are worn or heavily contaminated. During replacement, the operator simply pulls the trapezoidal locking block 20 out of the trapezoidal locking slot 19 and pushes the new cleaning plate 12 into place, simplifying the maintenance process and reducing maintenance costs.

[0025] This invention, through the aforementioned structure, achieves automated cleaning of elevator hall door guide rails without manual intervention, significantly improving cleaning efficiency and quality. Simultaneously, the device operates synchronously with the normal operation of the hall door mounting plate, eliminating the need for additional elevator start-stop operations and avoiding disruption to normal elevator use. To better enable those skilled in the art to fully understand and implement this invention, the following supplementary explanation of the device's operating principle and implementation steps is provided in conjunction with a specific application scenario.

[0026] During the daily operation of the elevator, the hall door mounting plate 1 moves along the guide rail 2 via the rollers 6 to open and close the elevator hall door. During this process, the cleaning component 5 moves synchronously with the hall door mounting plate 1 and achieves automated cleaning of the surface and sides of the guide rail 2 through a mechanical linkage structure.

[0027] First, when the elevator hall door starts, the hanging wheel 6 rolls along the guide rail 2 and drives the connecting shaft 14 to rotate synchronously. The rotation of the connecting shaft 14 drives the eccentric disk 8 to rotate, and the eccentric disk 8 converts the rotational motion into the linear reciprocating motion of the slider 10 in the guide groove 13 through the connecting rod 9. Since the slider 10 is fixedly connected to the L-shaped connecting plate 11, the motion of the slider 10 is further transmitted to the cleaning plate 12, causing the cleaning plate 12 to generate high-frequency reciprocating motion. The bristles 15 on the lower surface of the cleaning plate 12 repeatedly brush the top and sides of the guide rail 2 in the high-frequency reciprocating motion, thereby removing the attached dust, hair and other debris.

[0028] Secondly, the spring 18 in the adjusting assembly 4 ensures that the cleaning plate 12 is always in close contact with the surface of the guide rail 2 through its elastic force. The guide rod 17 on the horizontal connecting plate 16 passes through the guide hole of the L-shaped connecting plate 11 and is fixed by the nut 20, so that the cleaning plate 12 can float up and down within a certain range under the action of the spring 18, which can adapt to the slight unevenness that may exist on the surface of the guide rail 2, and ensure that the contact pressure between the bristles 15 and the guide rail 2 remains stable, further improving the cleaning effect.

[0029] Furthermore, during long-term use, the bristles 15 may experience wear or contamination, affecting cleaning efficiency. In this case, the operator can quickly replace the cleaning plate 12 using the quick-release mechanism. Specifically, the trapezoidal locking block 20 on the cleaning plate 12 is pulled out from the trapezoidal locking slot 19 at the bottom of the horizontal connecting plate 16, and then the new cleaning plate 12 is pushed into place to complete the replacement. This not only simplifies the maintenance process but also significantly reduces maintenance time and costs.

[0030] Furthermore, the bristles 15 are made of nylon or polyester material, and their ends are rounded, which can effectively remove debris from the surface of the guide rail 2 while avoiding scratching damage to the surface of the guide rail 2. The distribution density of the bristles 15 on the lower surface of the cleaning plate 12 is optimized to ensure that it can fully cover the top and sides of the guide rail 2, thereby achieving efficient cleaning.

[0031] In summary, this device achieves automated cleaning of the elevator hall door guide rail 2 through mechanical linkage. During normal elevator operation, the cleaning component 5 can complete the cleaning work synchronously with the movement of the hall door mounting plate 1 without the need for additional elevator start-stop. This not only improves cleaning efficiency and quality but also avoids the impact of frequent elevator start-stop on normal use, meeting the needs of efficient elevator operation and maintenance in modern buildings.

[0032] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
