Description

Technical Field

[0001] This utility model relates to the field of handrail technology, specifically to an anti-aging multi-layer handrail. Background Technology

[0002] Escalator handrails are critical safety components of escalators, and their internal structural design directly affects the smoothness, durability, and passenger safety of operation. Handrails, which are easily exposed to the outdoor environment, inevitably age due to the corrosive effects of rain, ultraviolet rays, dirt, and oil stains during long-term use. Traditional steel structures using a single steel wire are also prone to serpentine swaying due to insufficient lateral stiffness. Furthermore, the durability and fatigue resistance of different materials in the inner sliding layer of the escalator handrail vary. All of these issues affect the lifespan of the handrail. Therefore, to address these problems, we provide an anti-aging multi-layered handrail. Utility Model Content

[0003] The purpose of this invention is to provide an anti-aging multi-layer handrail belt to optimize the anti-aging, lateral stiffness, durability and fatigue resistance performance of various parts of the handrail belt, thereby improving the service life of the handrail belt.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an anti-aging multi-layer handrail belt, comprising a composite anti-aging functional layer, a rubber outer layer, an internal frame layer and a nylon sliding layer arranged sequentially from the outside to the inside, wherein the composite anti-aging functional layer includes a hydrophobic layer and an anti-UV film, wherein the hydrophobic layer is coated on the surface of the rubber outer layer and the anti-UV film is located outside the hydrophobic layer.

[0005] The internal framework layer includes stainless steel sheets, steel wires, and a polyester-amino buffer layer covering the surface of the stainless steel sheets and steel wires. The stainless steel sheets are wavy, and the steel wires are located at the troughs on the upper surface of the stainless steel sheets.

[0006] Preferably, the UV-resistant film is bonded to the hydrophobic layer using hot melt adhesive.

[0007] Preferably, the thickness of the UV-resistant film is 0.05-0.15 mm.

[0008] Preferably, the hydrophobic layer is a fluorine-containing coating, and the thickness of the hydrophobic layer is 20-50 μm.

[0009] Preferably, the stainless steel sheet is 316 stainless steel.

[0010] Preferably, the surface of the steel wire is coated with a graphene-modified epoxy resin layer.

[0011] This utility model has the following beneficial effects:

[0012] 1. A composite anti-aging functional layer is set on the outer surface of the rubber to improve anti-aging performance. The anti-UV film blocks ultraviolet rays and resists mechanical scratches to protect the inner layer. The hydrophobic layer prevents water vapor penetration and achieves anti-photoaging, hydrolytic aging and mechanical wear. At the same time, it is hydrophobic and oleophobic, preventing oil stains and dirt from contacting the outer layer of the rubber.

[0013] 2. The combination of corrugated stainless steel sheets and steel wires improves the lateral stiffness of the internal frame layer and has good tensile strength. The corrugated stainless steel sheets provide lateral stiffness and avoid the serpentine swing phenomenon. The polyester-amino buffer layer is used to isolate water and oxygen and absorb impact vibration, reduce metal fatigue and aging, and significantly improve the tensile strength and durability of the handrail belt, making it suitable for high-frequency and heavy-load scenarios.

[0014] 3. The nylon sliding layer has a smooth surface, good fatigue resistance, is stable in high humidity environments, has strong oil resistance, and maintains flexibility in low outdoor temperatures. Attached Figure Description
