Description

Technical Field

[0001] This utility model relates to the field of chain anti-wear technology, and in particular to a novel chain anti-wear device. Background Technology

[0002] In industrial production, chain drives are widely used in many scenarios such as conveying equipment, automated production lines, and warehousing and logistics equipment due to their stable transmission and strong load-bearing capacity. In most cases where the chain runs horizontally, the chain usually relies on metal guide rails for support and guidance to ensure the stability of its running trajectory.

[0003] Chains are typically supported by metal guide rails, and the friction between metals is the wear between hard objects, which is equivalent to mutual wear. Since the two materials are similar and have similar hardness, the lifespan of the chain rollers and guide rails decreases after long-term operation. At the same time, it is necessary to inspect and repair the worn parts, which increases the maintenance cost of the equipment and affects the production schedule. Utility Model Content

[0004] The purpose of this invention is to provide a novel chain anti-wear device that can reduce wear between the guide rail and the chain, improve service life, and significantly reduce equipment maintenance costs, resulting in significant economic benefits.

[0005] To achieve the above objectives, a novel chain anti-wear device is provided, comprising a plastic pad, a limiting plate, and a fixing component. The plastic pad is located on the inner surface of the guide rail and is precisely locked onto the guide rail. The outer surface of the plastic pad is provided with a limiting plate, which includes a transverse positioning plate and a longitudinal positioning plate. The limiting plate is fixedly installed on both ends and sides of the plastic pad by the fixing component.

[0006] According to the novel chain anti-wear device, the plastic pad is made of wear-resistant and tough plastic material, its shape is adapted to the top of the guide rail, and the upper surface of the plastic pad is a smooth surface to ensure that the chain runs smoothly on it.

[0007] According to the novel chain anti-wear device, the lateral positioning plate is disposed on both sides of the plastic pad, and the longitudinal positioning plate is disposed at both ends of the plastic pad, for limiting the lateral and longitudinal movement of the plastic pad.

[0008] According to the novel chain anti-wear device, a buffer pad is provided at the contact part between the limiting plate and the plastic pad. The buffer pad is made of rubber to avoid hard friction between the limiting plate and the plastic pad, which would damage the plastic pad.

[0009] According to the novel chain anti-wear device, the fixing member is a bolt, the outer surface of the limiting plate is provided with a through hole that matches the fixing member, and the guide rail is provided with a corresponding threaded hole. The fixing member passes through the through hole and is threadedly connected to the guide rail, thereby fixing the limiting plate on the guide rail.

[0010] This utility model has the following beneficial effects: 1. Compared with existing technologies, by setting up plastic pads, the chain and guide rail do not directly contact each other. The guide rail only plays a supporting role and will not cause wear. At the same time, the chain will not wear when running on the plastic pads, which are much less hard than itself. Only the plastic pads will show some wear. After running for a period of time, the wear of the chain, guide rail and plastic pads is not obvious, and the protection effect on the chain and guide rail is obvious.

[0011] 2. Compared with existing technologies, the cost of replacing the easily damaged plastic pad is much lower than the cost of replacing the chain and guide rail, which can significantly reduce the maintenance cost of the equipment and has obvious economic benefits. Attached Figure Description

[0012] The present invention will be further described below with reference to the accompanying drawings and embodiments; Figure 1 This is a schematic diagram of the overall structure of a novel chain anti-wear device according to this utility model; Legend: 1. Plastic pad; 2. Limiting plate; 3. Fixing component. Detailed Implementation

[0013] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0014] Reference Figure 1This utility model discloses a novel chain anti-wear device, comprising a plastic pad 1, a limiting plate 2, and a fixing member 3. The plastic pad 1 is located on the inner surface of the guide rail and is precisely fitted onto the guide rail. The plastic pad 1 is made of wear-resistant and tough plastic, and its shape is adapted to the top of the guide rail. The upper surface of the plastic pad 1 is smooth to ensure that the chain runs smoothly on it. The limiting plate 2 is provided on the outer surface of the plastic pad 1. The limiting plate 2 includes a transverse positioning plate and a longitudinal positioning plate. The transverse positioning plate is located on both sides of the plastic pad 1, and the longitudinal positioning plate is located on the plastic pad 1. The two ends of the limiting plate 2 are used to restrict the lateral and longitudinal movement of the plastic pad 1. A buffer pad is provided at the contact part between the limiting plate 2 and the plastic pad 1. The buffer pad is made of rubber to avoid hard friction between the limiting plate 2 and the plastic pad 1 and damage to the plastic pad 1. The limiting plate 2 is fixedly installed on both ends and sides of the plastic pad 1 by the fixing member 3. The fixing member 3 is a bolt. The outer surface of the limiting plate 2 has a through hole that matches the fixing member 3. The guide rail has a corresponding threaded hole. The fixing member 3 passes through the through hole and is threadedly connected to the guide rail, thereby fixing the limiting plate 2 on the guide rail.

[0015] Working principle: In actual use, the chain runs on the plastic pad 1. Since the hardness of the plastic pad 1 is much lower than that of the chain, the chain will not be worn. At the same time, the chain does not directly contact the guide rail, so the guide rail will not be worn. After a period of operation, the wear of the plastic pad 1 should be checked regularly. When the plastic pad 1 is worn to a certain extent and affects the operation of the chain, simply unscrew the fixing part 3, remove the limit plate 2, replace the plastic pad 1 with a new one, and then reinstall the limit plate 2 and the fixing part 3.

[0016] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
