Description

Technical Field

[0001] This utility model relates to the field of escalator roller technology, and in particular to a waterproof escalator roller. Background Technology

[0002] Escalators are continuously operating mechanized transportation equipment, mainly used to transport people between different floors of a building. They are characterized by convenience, efficiency, and uninterrupted operation, and are widely used in densely populated places such as shopping malls, subway stations, airports, train stations, and large supermarkets. Escalator rollers are key components in the escalator operating system, mainly used to support, guide, or drive the moving parts of the escalator, such as the steps and handrails, to ensure the smooth, safe, and efficient operation of the escalator.

[0003] Existing escalator rollers are not waterproofed on the sides during use, which allows moisture and dust to enter the bearings, causing jamming or corrosion and affecting the service life of the escalator rollers. Utility Model Content

[0004] The purpose of this utility model is to provide a waterproof escalator roller to solve the problem that existing escalator rollers are inconvenient to waterproof the sides of the rollers.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a waterproof roller for an escalator, including a rotating rod;

[0006] The rotating rod has a mating groove inside, a bearing is installed on the outer wall of the rotating rod, a roller body is installed on the outer wall of the bearing, a slot is opened inside the roller body, and a threaded hole is installed inside the roller body;

[0007] The outer wall of the roller body is equipped with a protective plate. A docking block is fixedly connected to one side of the protective plate, and a locking block is fixedly connected to another side of the protective plate. A through groove is opened inside the protective plate, and an internal hexagon bolt is installed inside the through groove.

[0008] Preferably, the docking block forms a rotating structure with the rotating rod via the docking groove, and the roller body forms a rotating structure with the rotating rod via the bearing, which allows the docking block to rotate along the docking groove.

[0009] Preferably, the roller body is connected to the card block by a card slot, and the card block is symmetrically arranged with respect to the central axis of the protective plate, so that the card block can be inserted into the card slot for docking.

[0010] Preferably, the protective plate is movably connected to the internal hexagon bolt via a through groove, and the internal hexagon bolt is threadedly connected to the roller body via a threaded hole, so that one end of the protective plate can be inserted into the internal hexagon bolt for limiting.

[0011] Preferably, the outer wall of the roller body is fixedly connected to an epoxy resin coating, the outer wall of the epoxy resin coating is fixedly connected to a polyurethane coating, and the outer wall of the polyurethane coating is fixedly connected to a PTFE coating.

[0012] Preferably, the epoxy resin coating and the polyurethane coating are tightly bonded together, and the polyurethane coating is placed between the epoxy resin coating and the PTFE coating, which allows it to better adhere to the metal substrate, seal the micropores of the substrate, prevent moisture from penetrating into the substrate, and at the same time provide a smooth base for the intermediate coating.

[0013] Preferably, the polyurethane coating and the PTFE coating are tightly bonded together, and the PTFE coating and the polyurethane coating are arranged in parallel, which can improve the hydrophobicity of the roller body surface.

[0014] The advantages of the waterproof roller for escalators provided by this utility model are as follows:

[0015] The roller body is equipped with a rotating rod, a roller body, a slot, a threaded hole, a protective plate, a locking block, a through slot, and internal hex bolts. By moving the protective plate, the mating block is inserted into the mating slot opened inside the rotating rod. The two internal hex bolts are passed through the through slot and rotated, so that the ends of the internal hex bolts can be inserted into the threaded hole for limiting. The protective plate blocks and protects the side of the roller body, which facilitates waterproofing and dustproofing of the side of the roller body, and further improves the service life of the roller body.

[0016] Furthermore, the interlocking action of the card block and the card slot can improve the stability of the assembly connection between the protective plate and the roller body;

[0017] By using a roller body, an epoxy resin coating, a polyurethane coating, and a PTFE coating, and by fixing the epoxy resin coating to the outer wall of the roller body, it can better adhere to the metal substrate, seal the micropores of the substrate, prevent moisture from penetrating into the substrate, and at the same time provide a flat base for the intermediate coating.

[0018] Furthermore, a polyurethane coating is fixedly connected to the outer wall of the epoxy resin coating, which can absorb the vibration during the operation of the escalator, reduce the rigid friction between the rollers and the shaft, and has good compatibility with the epoxy resin coating and PTFE coating, thus preventing delamination and peeling.

[0019] Furthermore, the PTFE coating is fixedly connected to the outer wall of the polyurethane coating, which can improve the hydrophobicity of the surface. Water droplets roll off the surface in a spherical shape, enhancing the waterproof effect and reducing frictional resistance with the escalator guide rail, thus reducing operating noise.

The mating block 8 forms a rotating structure with the rotating rod 1 through the mating groove 2, and the roller body 4 forms a rotating structure with the rotating rod 1 through the bearing 3. The roller body 4 is engaged with the locking block 9 through the slot 5. The locking block 9 is symmetrically arranged around the central axis of the protective plate 7. The protective plate 7 is movably connected to the internal hex bolt 11 through the through groove 10, and the internal hex bolt 11 is threadedly connected to the roller body 4 through the threaded hole 6.

[0029] By moving the protective plate 7, the docking block 8 is engaged into the docking groove 2 inside the rotating rod 1, and at the same time, the two locking blocks 9 are engaged into the locking groove 5 inside the roller body 4. The two hexagonal bolts 11 are passed through the through groove 10 and rotated. Since the hexagonal bolts 11 are threadedly connected to the roller body 4 through the threaded hole 6, the ends of the hexagonal bolts 11 can be inserted into the threaded hole 6 for limiting, so that the protective plate 7 blocks and protects the side of the roller body 4.

The epoxy resin coating 12 and the polyurethane coating 13 are tightly bonded together, and the polyurethane coating 13 is placed between the epoxy resin coating 12 and the PTFE coating 14. The polyurethane coating 13 and the PTFE coating 14 are tightly bonded together, and the PTFE coating 14 and the polyurethane coating 13 are arranged in parallel.

[0031] An epoxy resin coating 12 is fixedly connected to the outer wall of the roller body 4, which allows it to adhere better to the metal substrate, seal the micropores of the substrate, prevent moisture from penetrating into the substrate, and provide a flat base for the intermediate coating. Since a polyurethane coating 13 is fixedly connected to the outer wall of the epoxy resin coating 12, it can absorb the vibration of the escalator during operation and reduce the rigid friction between the roller and the shaft. A PTFE coating 14 is fixedly connected to the outer wall of the polyurethane coating 13, which can improve the hydrophobicity of its surface. Water droplets roll off the surface in a spherical shape, which enhances the waterproof effect.
