[0021] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.
[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0023] Example 1
[0024] See Figures 1-4 This embodiment provides a cleaning device for elevator sills, including a mounting box 1, which serves as the main structure of the entire cleaning device and is used to house and fix various components. Casters 2 are provided on both sides of the mounting box 1 to improve the convenience of the cleaning device. A push handle 3 is fixedly connected to the outer wall of the mounting box 1. The cleaning device, including a cylinder 41, is installed inside the mounting box 1. The cylinder 41 is fixedly connected to the inner wall of the mounting box 1. An L-shaped plate 42 is fixedly connected to the output end of the cylinder 41. A motor 43 is fixedly connected to the outer wall of the L-shaped plate 42. A rotating shaft 44 is fixedly connected to the output end of the motor 43. A cleaning roller 45 is fixedly sleeved on the outer wall of the rotating shaft 44, which is a direct tool for cleaning the elevator sill. Its rotation can effectively remove dust and impurities from the elevator sill.
[0025] The cleaning device includes a collection box 410, which is fixedly connected to the inner wall of the mounting box 1. A vacuum cleaner 46 is provided on the outer wall of the collection box 410. A vacuum cleaning hose 47 is fixedly connected to the bottom of the collection box 410, and a vacuum cleaning cover 48 is fixedly connected to the other end of the vacuum cleaning hose 47.
[0026] A fixing block 49 is fixedly connected to the outer wall of the L-shaped plate 42, a vacuum hose 47 moves through the fixing block 49, and a vacuum hood 48 is fixedly connected to the fixing block 49.
[0027] The dust hood 48 is located on the side of the cleaning roller 45.
[0028] In practical use, the above-mentioned equipment is first pushed to the upper end of the elevator sill by the push handle 3. Then, the cylinder 41 is started to drive the L-shaped plate 42 to descend. The L-shaped plate 42 will then drive the motor 43, the rotating shaft 44 and the cleaning roller 45 to descend. When the cleaning roller 45 moves to the appropriate position, the motor 43 is started to drive the rotating shaft 44 to rotate. The cleaning roller 45 will then rotate accordingly, thereby cleaning out the dust and impurities inside the elevator sill. At the same time, as the L-shaped plate 42 descends, the fixing block 49 will also descend, and the dust suction hood 48 will descend accordingly. Then, the vacuum cleaner 46 will be started, and the dust and impurities will be sucked into the collection box 410 through the vacuum hose 47.
[0029] Example 2
[0030] See Figures 1-4 Based on Embodiment 1, the interior of the mounting box 1 is equipped with an anti-fall device, which includes a rotating shaft 51. The rotating shaft 51 is fixedly connected to the inner wall of the mounting box 1 through a bearing. The other end of the rotating shaft 51 is fixedly connected to a connecting rod 52, which is used to transmit the movement of the rotating shaft 51 to the dustproof plate 53. The outer wall of the connecting rod 52 is fixedly connected to the dustproof plate 53, which is used to prevent dust and impurities on the outer wall of the cleaning roller 45 from falling off. The outer wall of the rotating shaft 51 is fixedly fitted with a gear 55, and the outer wall of the L-shaped plate 42 is fixedly connected to a toothed plate 54.
[0031] Gear 55 is located on the side of gear plate 54 and meshes with gear plate 54.
[0032] When the L-shaped plate 42 descends, it will drive the toothed plate 54 to descend, and the gear 55 that meshes with it will rotate accordingly, which will cause the rotating shaft 51 to rotate. Then, the connecting rod 52 will drive the dustproof plate 53 to rotate, so that when cleaning is not required, the dustproof plate 53 will prevent the dust adhering to the outer wall of the cleaning roller 45 from falling off.
[0033] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
