Description

Technical Field

[0001] This utility model relates to the field of escalator technology, and in particular to a handrail cleaning brush device. Background Technology

[0002] Styrene-butadiene rubber (SBR), the most widely used material in escalators, contains anti-aging agents. These agents protect the handrail surface and prevent rubber aging. However, as temperatures rise, these agents migrate more rapidly to the handrail surface and combine with dust in the air to form "black powder," which adheres to the handrail surface and contaminates the areas where passengers come into contact with it. With the continued trend of cost reduction in the escalator market, the quality of the SBR handrail surface material has declined. Furthermore, due to the increasing market demand for longer warranty periods for handrails, the proportion of anti-aging components in SBR handrails has increased. The combination of these two factors has led to a more severe "black powder" phenomenon on the handrail surface. To reduce complaints caused by "black powder" and achieve the best cost-effectiveness, it is necessary to install cleaning brush devices on SBR handrails to remove the surface "black powder."

When a component is referred to as "connected to" another component, it can be directly connected to the other component or may have an intervening component present.

[0020] Furthermore, it should be noted that the directional terms such as left, right, up, and down used in the embodiments of this utility model are only relative concepts or references to the normal use of the product, and should not be considered restrictive. The implementation of this utility model will be described in detail below with reference to specific embodiments.

[0021] As attached Figure 1 The image shows a handrail cleaning brush device according to this utility model, comprising two angular pieces 2 for mounting on the escalator skirt panel 1, as shown in the attached diagram. Figure 2 As shown, the angled component 2 includes a first bent surface 21 and a second bent surface 22 that are perpendicular to each other. The first bent surface 21, which is in contact with the escalator skirt panel 1, has an elongated hole 211. The second bent surface 22 has a threaded hole 221. The second bent surfaces 22 of the two angled components 2 are located on the same horizontal plane. A dust collection box 3 is installed on the second bent surface 22. The two angled components 2 are evenly connected to both ends of the dust collection box 3. The bottom surface of the dust collection box 3 has two through holes corresponding to the threaded holes 221. The dust collection box 3 contains a bent component 4, a first screw 5, and a brush 6, as shown in the attached diagram. Figure 3 As shown, the bent component 4 includes a base plate 41 that fits against the bottom surface of the dust collection box 3 and a side plate 42 perpendicular to the base plate 41. The base plate 41 has a first mounting hole 411 corresponding to the through hole. A first screw 5 passes through the first mounting hole 411 and the through hole in sequence and engages with a threaded hole 221 on the second bent surface 22, thus fixing the bent component 4, the dust collection box 3, and the angled component 2 together. A brush 6 is connected to the side plate 42 and contacts the handrail strap 7 to clean the moving handrail strap 7.

[0022] The escalator skirt panel 1 has pre-drilled fixing holes, with elongated holes 211 corresponding to these holes. The angled member 2 and the escalator skirt panel 1 are fastened together with bolts and nuts. The elongated holes 211 on the angled member 2 facilitate adjustment of the height of the brush 6, ensuring that the brush 6 can fully contact the handrail belt 7 to clean the "black powder" on its surface. In this embodiment, the elongated holes 211 extend along the length of the first bent surface 21. During installation, the bolts can be first passed through the fixing holes and screwed into a loose state with the nuts. The first bent surface 21 of the angled member 2 is then placed against the escalator skirt panel 1, allowing the elongated holes 211 to be inserted downwards along the bolts. Finally, the nuts are tightened to secure the angled member 2 and the escalator skirt panel 1 together, making installation more convenient and preventing smaller accessories such as bolts and nuts from falling out or being lost.

[0023] The brush 6 includes a connected wooden handle 61 and boar bristles 62. The wooden handle 61 is connected to the side plate 42, and the boar bristles 62 contact the bottom surface of the handrail belt 7. Soft boar bristles are used as the brush bristles, ensuring reliable material quality and preventing scratches on the surface of the handrail belt 7. The wooden handle 61 has a through-hole 611 machined on its side, and the side plate 42 has a corresponding second mounting hole 421. The wooden handle 61 and the side plate 42 are connected by a second screw 8 that passes through the second mounting hole 421 and enters the connecting hole 611.

[0024] This utility model's handrail belt 7 cleaning brush 6 device is easy to install and maintain, fully considering on-site modification conditions. No drilling or welding is required on-site. The device can be pre-assembled before shipment and directly installed on the existing holes of the escalator skirt board 1 support component using two sets of bolts and nuts. During on-site maintenance, a vacuum cleaner can be used to remove dust from the dust collection box. The height of the angled component 2 can be flexibly adjusted according to the height difference between the escalator skirt board 1 and the handrail belt 7 of different ladder types. It has good adaptability and a wide range of applications.
