Description

Technical Field

[0001] The utility model belongs to the technical field of escalator handrail cleaning, in particular to an automatic escalator handrail cleaning device. Background Art

[0002] According to the patent document with the authorization announcement number "CN220055982U" and the invention name "An escalator handrail cleaning device", the specification states: When the escalator is working, the handrail drives the rubber wheel to rotate during the forward movement, thereby driving the driving gear to rotate in the same direction through the driving shaft, and the driving gear then drives the driven gear and the driven shaft to rotate in the opposite direction. The rotating rod installed on the driven gear drives the hinge rod, thereby pushing the hinge seat forward or pulling the hinge seat backward. The guide column installed on the hinge seat moves with the hinge seat, and then pushes the piston plate to push or pull. When the piston plate is pushed forward, the water in the water storage tank is squeezed out along the sponge pad through the water guide pipe and finally flows into the water storage box, so that the sponge pad fully absorbs the water and cleans the escalator handrail. Among them, when the water flows along the sponge pad, the water flow will bring out the dust on the sponge pad, so that the dust originally on the top of the sponge pad enters the water storage box, but the following defects still exist:

[0003] The dust on the sponge pad is discharged by squeezing the sponge pad to form a water flow. However, the squeezing process tends to reduce the volume of the sponge pad. The dust may be trapped in the folds of the sponge pad caused by the pressure, resulting in poor self-cleaning effect and affecting the subsequent cleaning of the handrail. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides an escalator handrail cleaning device, which effectively solves the problem that the self-cleaning effect of the sponge pad is poor, affecting the subsequent cleaning of the handrail.

Specific embodiments

[0022] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment 1, given by Figures 1-4 The present utility model relates to an escalator handrail cleaning device, including a water tank 1. An armrest cleaning assembly 6 is installed at the top end of the water tank 1, and a self-cleaning assembly 7 is installed inside the water tank 1;

[0024] The handrail cleaning assembly 6 includes two fixing plates 601 symmetrically installed at the top end of the water tank 1. A cleaning roller 602 is provided between the two fixing plates 601. A rotating shaft 603 is coaxially installed on the cleaning roller 602. The rotating shaft 603 is rotatably connected to the fixing plate 601. The inside of the water tank 1 is filled with water. The bottom end of the cleaning roller 602 is located in the water. The outer wall of the cleaning roller 602 is in close contact with the surface of the handrail. The bottom end of the cleaning roller 602 is located in the water. When the handrail moves, it drives the cleaning roller 602 to rotate, so that the cleaned part of the cleaning roller 602 enters the water for self-cleaning, which is convenient for the cleaning effect of the cleaning roller 602 on the surface of the handrail.

[0025] The self-cleaning component 7 includes two sliding blocks 701 symmetrically arranged below the cleaning roller 602. The top ends of the sliding blocks 701 are evenly installed with brush bristles 702, and the brush bristles 702 are in contact with the bottom wall of the cleaning roller 602. Two horizontal guide rods 703 are symmetrically installed inside the water tank 1, and the sliding blocks 701 are slidably connected to the horizontal guide rods 703. A connecting plate 708 is installed on the front of the sliding block 701. A horizontal plate 707 is arranged below the connecting plate 708. A connecting rod 709 is arranged between the connecting plate 708 and the horizontal plate 707. The two ends of the connecting rod 709 are respectively hinged to the connecting plate 708 and the horizontal plate 707. When the horizontal plate 707 moves downward, it can pull the two sliding blocks 701 closer to each other through the connecting rod 709. A vertical guide rod 704 is fixedly installed on the inner bottom wall of the water tank 1, and the horizontal plate 707 is slidably connected to the vertical guide rod 704. A limit plate 705 is fixedly installed at the top end of the vertical guide rod 704. A spring 706 is fixedly installed at the bottom end of the limit plate 705, and the bottom end of the spring 706 is fixedly connected to the horizontal plate 707. Longitudinal rods 710 are fixedly installed at the top of both ends of the horizontal plate 707. Pressure-receiving plates 711 are fixedly installed at the top ends of the longitudinal rods 710. Cam 712 is symmetrically installed on the rotating shaft 603. The two pressure-receiving plates 711 are respectively in contact with the bottom walls of the two cams 712. Cam 712 is installed on the rotating shaft 603. Under the action of the rotation of the cam 712 and the spring 706, the horizontal plate 707 moves longitudinally back and forth, driving the two sliding blocks 701 to move reciprocally relative to each other, so that the brush bristles 702 continuously brush the bottom wall of the cleaning roller 602, improving the cleaning effect of the cleaning roller 602 on the handrail.

[0026] Moving self-locking wheels 2 are installed at the four corners of the bottom end of the water tank 1. A push handle 5 is installed on one side of the water tank 1. A drain pipe 3 is installed at the bottom end of one end of the water tank 1. The drain pipe 3 is communicated with the inside of the water tank 1. A valve 4 is installed on the drain pipe 3.

[0027] Working principle: During work, first, the water tank 1 is pushed to the lower part of the escalator handrail through the push handle 5 and the moving self-locking wheels 2, so that the outer wall of the cleaning roller 602 is closely attached to the surface of the escalator handrail. Then, the moving self-locking wheels 2 are locked to prevent the water tank 1 from moving. Then, water is flushed into the water tank 1 to submerge the bottom end of the cleaning roller 602. The escalator is started. As the escalator handrail moves with the escalator, due to the close attachment of the handrail to the outer wall of the cleaning roller 602, under the action of friction, the movement of the handrail drives the cleaning roller 602 to rotate, so that the cleaning roller 602 continuously contacts the outer wall of the handrail to clean the handrail. At the same time, the cleaned cleaning roller 602 enters the water for self-cleaning, improving the cleaning effect of the handrail.

[0028] During the rotation of the cleaning roller 602, the cam 712 is driven to rotate. When the cam 712 generates a downward pressure on the pressure-receiving plate 711, the transverse plate 707 is pushed to move downward, and the two sliding blocks 701 are pulled closer to each other through the connecting rod 709. After the pressure disappears, the transverse plate 707 moves upward under the elastic force of the spring 706, and the two sliding blocks 701 are pushed away from each other through the connecting rod 709, so that the two sliding blocks 701 continuously perform reciprocating relative movement under the cleaning roller 602, and the brush bristles 702 continuously brush the bottom wall of the cleaning roller 602, improving the cleaning effect of the cleaning roller 602 on the armrest.

[0029] The above embodiments are only for explaining the technical concept and features of the present invention, and the purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly. It is not intended to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
