Description

Technical Field

[0001] This utility model relates to the field of escalator technology, and in particular to an automatic sidewalk cleaning device. Background Technology

[0002] In public places such as shopping malls, subway stations, and airports, moving walkways are used very frequently. Their sliding handrails are in constant contact with a large number of people and are prone to accumulating dust, stains, and even germs. This not only affects the appearance but also poses a hygiene hazard. Therefore, cleaning and maintaining the sliding handrails of moving walkways is of utmost importance.

[0003] Currently, existing automatic walkway cleaning devices on the market have many shortcomings. On the one hand, the cleaning components of most devices have fixed heights and widths, making it difficult to adapt to automatic walkways of different specifications. When encountering scenarios with significant differences in handrail height or width, they cannot achieve effective cleaning. On the other hand, the cleaning pad replacement process of some devices is cumbersome, requiring the disassembly of multiple parts with tools, consuming a lot of maintenance time and labor costs. In addition, existing cleaning devices also have defects in operational stability. Unreasonable structural design makes them prone to shaking or displacement during cleaning, affecting the cleaning effect and even interfering with the normal operation of the automatic walkway. Furthermore, the devices themselves have a shortened lifespan due to uneven stress. Utility Model Content

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Reference Figures 1 to 5As shown, this utility model provides a technical solution: an automatic sidewalk cleaning device, including an escalator body 1 and an adjusting frame 6. A sliding handrail 2 is provided on the surface of the escalator body 1. The adjusting frame 6 is located below the sliding handrail 2, and a bidirectional screw 9 is rotatably connected to the inner wall of the adjusting frame 6. A handle 13 is fixedly connected to one end of the bidirectional screw 9, and a sliding frame 10 is threadedly connected to the surface of the bidirectional screw 9. A slot 14 is opened on the surface of the sliding frame 10, and a retaining plate 15 is slidably connected to the inner wall of the slot 14. A fixing frame 16 is fixedly connected to one side of the retaining plate 15, and a cleaning pad 17 is provided on the surface of the fixing frame 16. By setting the retaining plate 15 and the slot 14, the fixing frame 16 and the cleaning pad 17 can be easily replaced, which is convenient for daily cleaning operations. At the same time, rotating the handle 13 drives the bidirectional screw 9 to rotate, which allows the two sliding frames 10 to move synchronously in opposite directions, so that the cleaning pad 17 fits the surface of the sliding handrail 2, adapting to sliding handrails 2 of different widths and improving the versatility of the device.

[0026] Reference Figure 1 , Figure 4 and Figure 5 As shown in this embodiment: Slide grooves 12 are provided on both sides of the inner wall of the adjusting frame 6. A slider 11 is slidably connected to the inner wall of the slide groove 12. One side of the slider 11 is fixedly connected to the surface of the sliding frame 10. By setting the slide grooves 12 and the slider 11, the stability of the sliding frame 10 during movement can be enhanced, preventing shaking and displacement. The cross-section of the sliding frame 10 and the fixed frame 16 is "L" shaped, and a fixed slot 20 is provided on one side of the sliding frame 10. A fixed screw 18 is fixedly connected to one side of the fixed frame 16. The fixed screw 18 is slidably connected to the inner wall of the fixed slot 20, and a fixed screw sleeve 19 is threaded onto the surface of the fixed bolt. By inserting the fixed screw 18 on the fixed frame 16 into the fixed slot 20, and then fixing the fixed screw 18 by rotating the fixed screw, it is ensured that the device will not shift due to vibration during the cleaning process.

[0027] Reference Figure 2 and Figure 3 As shown, specifically, an extension rod 5 is fixedly connected to the lower end of the adjusting frame 6, a sliding frame 4 is slidably connected to the lower end of the extension rod 5, and a mounting plate 3 is fixedly connected to the lower end of the sliding frame 4. The mounting plate 3 is fixedly connected to the surface of the escalator body 1 by bolts. A fixing bolt 7 is provided on the surface of the sliding frame 4. A reinforcing rod 8 is fixedly connected to the upper end of the extension rod 5, and the top of the reinforcing rod 8 is fixedly connected to the lower surface of the adjusting frame 6. Through the sliding connection of the extension rod 5 in the sliding frame 4, the height of the adjusting frame 6 can be adjusted up and down, and then fixed by the fixing bolt 7, so that it can be adapted to sliding handrails 2 of different heights. At the same time, the reinforcing plate and reinforcing rod 8 at the upper end of the extension rod 5 are connected to the adjusting frame 6, which can distribute the pressure during cleaning, prevent the extension rod 5 from deforming due to force, and improve the durability and safety of the device.

[0028] Working principle: During use, the mounting plate 3 is first fixed to the escalator body 1 with bolts, providing a stable foundation for overall operation. When it is necessary to adjust the height of the cleaning device to adapt to the sliding handrail 2 of different specifications of the moving walkway, the operator can loosen the fixing bolt 7 on the surface of the sliding frame 4, allowing the extension rod 5 to slide up and down within the sliding frame 4, driving the adjustment frame 6 fixed to the upper end of the extension rod 5 and the components inside the frame to rise and fall synchronously. After adjusting to the appropriate height, tighten the fixing bolt 7 to lock the position of the extension rod 5, completing the height adaptation. At the same time, the reinforcing plate and reinforcing rod 8 at the upper end of the extension rod 5 are connected to the lower surface of the adjustment frame 6, forming a stable triangular support structure, dispersing the pressure during cleaning, preventing the extension rod 5 from deforming under force, and ensuring the durability and safety of the device during cleaning operations. In terms of width adjustment, the operator rotates the handle 13 at one end of the bidirectional screw 9, which is rotatably connected to the inner wall of the adjustment frame 6. Because the surface of the bidirectional screw 9 has two sections with opposite rotation directions... When the screw rotates, the two sliding brackets 10 connected to it move synchronously in opposite directions along the screw under the action of the thread force. At the same time, the fixed bracket 16 connected to the sliding bracket 10 and the cleaning pad 17 on the surface of the fixed bracket 16 also move, so as to accurately fit the surface of the sliding armrest 2 of different widths and realize the adjustment of the cleaning range. When the cleaning pad 17 needs to be replaced, since the sliding bracket 10 has a slot 14, the locking plate 15 on one side of the fixed bracket 16 slides with the slot 14. When the cleaning pad 17 needs to be replaced, the operator only needs to pull out the locking plate 15 to remove the fixed bracket 16 and the cleaning pad 17. When installing a new component, the locking plate 15 is aligned with the slot 14 and inserted. After the fixing screw 18 on one side of the fixed bracket 16 is inserted into the fixing slot 20 of the sliding bracket 10, it is tightened with the fixing screw sleeve 19. This can effectively transmit vibration and external force during the cleaning process and prevent the fixed bracket 16 and the cleaning pad 17 from shifting.
