Description

Technical Field

[0001] This utility model relates to the field of idler rollers, and in particular to a corrosion-resistant and wear-resistant idler roller. Background Technology

[0002] Idler rollers are an important component of belt conveyors. Their function is to support the conveyor belt and the weight of the materials, ensuring the stable operation of the conveyor belt. Chinese patent application number CN202220352762.8 discloses a high-efficiency wear-resistant and long-life idler roller. By setting a wear-resistant layer and an inner liner, the wear-resistant layer is made of 1mm thick 65Mn material, and the inner liner is made of Q235 material. This improves the wear resistance of the roller surface while ensuring excellent welding performance between the roller skin and the bearing seat, thereby increasing the service life of the idler roller. When Q235 steel is used as a raw material for idler roller production, its cost is low but its wear resistance is not high. However, when Q235 steel is quenched in salt water at 900-940°C, its wear resistance can be greatly improved, and the resulting idler roller has good wear resistance and corrosion resistance. However, in most existing idler rollers, the corrosion-resistant and wear-resistant structure is integrated with the idler roller itself. The wear-resistant structure is difficult to modularly disassemble and reassemble. Therefore, if a part of the corrosion-resistant and wear-resistant structure is damaged, it may be necessary to replace the entire idler roller, which results in high maintenance costs. To address this, we propose a corrosion-resistant and wear-resistant idler roller. Utility Model Content

[0003] To overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a corrosion-resistant and wear-resistant idler roller. By setting a wear-resistant and corrosion-resistant component, which is composed of multiple arc-shaped wear-resistant plates, it is detachably fixed to the idler roller shaft and the fixing ring by insert plate, pressure plate and locking screw one and locking screw two. When a wear-resistant plate is damaged, only the damaged single arc-shaped wear-resistant plate needs to be replaced, instead of replacing the entire idler roller, which greatly reduces maintenance costs and downtime.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A corrosion-resistant and wear-resistant idler roller includes an idler roller body, a wear-resistant component connected to the outside of the idler roller body, a wear-resistant and corrosion-resistant component connected to the outside of the wear-resistant component, and a fixing component connected to the outside of the wear-resistant and corrosion-resistant component. The wear-resistant and corrosion-resistant component includes multiple arc-shaped wear-resistant plates, all of which are detachably connected to the outside of the idler roller body. Fan-shaped wear-resistant plates are fixedly connected to both ends of the arc-shaped wear-resistant plates. The surface of the arc-shaped wear-resistant plates is coated with an anti-corrosion coating. A pressure plate is fixedly connected to the outer end of the fan-shaped wear-resistant plates. An insert plate is fixedly connected to the lower end of the fan-shaped wear-resistant plates. Multiple grooves are provided at the lower end of the arc-shaped wear-resistant plates, and the multiple grooves are arranged at equal intervals.

[0005] By setting up wear-resistant and corrosion-resistant components, which consist of multiple arc-shaped wear-resistant plates, the components are detachably fixed to the idler roller shaft and the retaining ring by insert plates, pressure plates and locking screws one and two. When a wear-resistant plate is damaged, only the damaged arc-shaped wear-resistant plate needs to be replaced, instead of replacing the entire idler roller, which greatly reduces maintenance costs and downtime. The surface of the arc-shaped wear-resistant plate is coated with an anti-corrosion coating, which effectively resists corrosive environments (such as moisture, chemicals, etc.), prevents the surface of the idler roller from rusting, and further extends the service life of the idler roller.

[0006] Furthermore, the fixing component includes a roller shaft, which is fixedly connected to the left and right ends of the roller body. A fixing ring is fixedly connected to the outside of the roller shaft, and an annular slot is provided on the outer wall of the fixing ring.

[0007] Furthermore, the insert plate is movably inserted into the interior of the annular slot, and the pressure plate is movably attached to the outer wall of the roller shaft.

[0008] Furthermore, the insert plate is detachably connected to the fixing ring and the annular slot via a locking screw, and the locking screw is threadedly connected to the insert plate, the fixing ring, and the annular slot.

[0009] Furthermore, the pressure plate and the idler roller shaft are detachably connected by a second locking screw, which is threaded to both the pressure plate and the idler roller shaft.

[0010] Furthermore, the wear-resistant component includes a wear-resistant sleeve, which is fixedly connected to the outer wall of the idler roller body, and the arc-shaped wear-resistant plate is detachably installed on the outside of the wear-resistant sleeve.

[0011] Furthermore, the outer wall of the wear-resistant sleeve is fixedly connected with multiple wear-resistant protrusions, which are arranged at equal intervals.

[0012] Furthermore, the wear-resistant protrusion is movably inserted into the inside of the groove, and the wear-resistant protrusion is adapted to the groove.

[0013] In summary, this utility model has the following beneficial effects: 1. By setting up wear-resistant and corrosion-resistant components, which consist of multiple arc-shaped wear-resistant plates, the components are detachably fixed to the idler roller shaft and the retaining ring by insert plates, pressure plates and locking screws one and two. When a wear-resistant plate is damaged, only the damaged single arc-shaped wear-resistant plate needs to be replaced, instead of replacing the entire idler roller, which greatly reduces maintenance costs and downtime. 2. The surface of the arc-shaped wear-resistant plate is coated with an anti-corrosion coating, which effectively resists corrosive environments (such as moisture, chemicals, etc.), prevents the surface of the idler roller from rusting, and further extends the service life of the idler roller.

[0018] Reference Figures 1-6 As shown, a corrosion-resistant and wear-resistant idler roller is provided in a preferred embodiment of the present invention. It includes an idler roller body 1, a wear-resistant component 2 connected to the outside of the idler roller body 1, a wear-resistant and corrosion-resistant component 3 connected to the outside of the wear-resistant component 2, and a fixing component 4 connected to the outside of the wear-resistant and corrosion-resistant component 3. The wear-resistant and corrosion-resistant component 3 includes multiple arc-shaped wear-resistant plates 301, all of which are detachably connected to the outside of the idler roller body 1. Both ends of the arc-shaped wear-resistant plates 301 are fixedly connected to fan-shaped wear-resistant plates 302. The surface of the arc-shaped wear-resistant plates 301 is coated with an anti-corrosion coating 303. The outer end of the fan-shaped wear-resistant plates 302 is fixedly connected to a pressure plate 304. The lower end of the fan-shaped wear-resistant plates 302 is fixedly connected to an insert plate 305. Multiple grooves 306 are provided at the lower end of the arc-shaped wear-resistant plates 301, and the multiple grooves 306 are arranged at equal intervals.

[0019] By setting up a wear-resistant and corrosion-resistant component 3, which consists of multiple arc-shaped wear-resistant plates 301, the component is detachably fixed to the idler roller shaft 401 and the fixing ring 402 by means of insert plate 305, pressure plate 304 and locking screw one 404 and locking screw two 405. When a wear-resistant plate is damaged, only the damaged single arc-shaped wear-resistant plate 301 needs to be replaced, instead of replacing the entire idler roller, which greatly reduces maintenance costs and downtime. The surface of the arc-shaped wear-resistant plate 301 is coated with an anti-corrosion coating 303, which effectively resists corrosive environments (such as moisture, chemicals, etc.), prevents the surface of the idler roller from rusting, and further extends the service life of the idler roller.

[0020] Reference Figures 1-6 As shown, the fixing component 4 includes a roller shaft 401, which is fixedly connected to the left and right ends of the roller body 1. A fixing ring 402 is fixedly connected to the outside of the roller shaft 401, and an annular slot 403 is provided on the outer wall of the fixing ring 402.

[0021] Reference Figures 1-6 As shown, the insert plate 305 is movably inserted into the inside of the annular slot 403, and the pressure plate 304 is movably attached to the outer wall of the idler roller shaft 401.

[0022] Reference Figures 1-6 As shown, the insert plate 305 is detachably connected to the fixing ring 402 and the annular slot 403 by a locking screw 404. The locking screw 404 is threadedly connected to the insert plate 305, the fixing ring 402 and the annular slot 403.

[0023] Reference Figures 1-6 As shown, the pressure plate 304 and the roller shaft 401 are detachably connected by a second locking screw 405. The second locking screw 405 is threadedly connected to both the pressure plate 304 and the roller shaft 401.

[0024] The fixing component 4 securely fixes the arc-shaped wear-resistant plate 301 through the annular slot 403 and locking screw 404 to prevent loosening. The connection between the pressure plate 304 and the roller shaft 401 through the locking screw 405 further enhances the stability of the overall structure, while the disassembly and assembly process is simple and quick.

[0025] Reference Figures 1-6 As shown, the wear-resistant component 2 includes a wear-resistant sleeve 201, which is fixedly connected to the outer wall of the roller body 1, and an arc-shaped wear-resistant plate 301 is detachably installed on the outside of the wear-resistant sleeve 201.

[0026] Reference Figures 1-6 As shown, the outer wall of the wear-resistant sleeve 201 is fixedly connected with multiple wear-resistant protrusions 202, which are arranged at equal intervals.

[0027] The wear-resistant component 2 includes a wear-resistant sleeve 201 and a wear-resistant protrusion 202, which cooperate with the groove 306 at the lower end of the arc-shaped wear-resistant plate 301 to form a tight wear-resistant structure, thereby improving the overall wear resistance of the idler roller and extending its service life.

[0028] Reference Figures 1-6 As shown, the wear-resistant protrusion 202 is movably inserted into the inside of the groove 306, and the wear-resistant protrusion 202 is adapted to the groove 306.

[0029] Specific implementation process: The arc-shaped wear-resistant plate 301, the fan-shaped wear-resistant plate 302, the wear-resistant sleeve 201, and the wear-resistant protrusion 202 can be made of high-chromium cast iron or wear-resistant steel. These materials have high hardness, excellent wear resistance and impact resistance, and are suitable for use in harsh working conditions. The anti-corrosion coating 303 can be made of epoxy resin coating or polyurethane coating. These coatings have good adhesion, chemical corrosion resistance and wear resistance, and can effectively isolate moisture and corrosive media, providing long-term anti-corrosion protection. In specific high-temperature environments, ceramic-based coatings can also be considered. The wear-resistant and corrosion-resistant component 3 consists of multiple arc-shaped wear-resistant plates 301. During installation, the insert plate 305 is inserted into the annular groove 306, and the wear-resistant protrusion 202 is inserted into the corresponding groove 306. It is detachably fixed to the idler roller shaft 401 and the fixing ring 402 by the insert plate 305, the pressure plate 304, and the locking screws 404 and 405. When a wear-resistant plate is damaged, only the damaged single arc-shaped wear-resistant plate 301 needs to be replaced, without replacing the entire idler roller, which greatly reduces maintenance costs and downtime. The surface of the arc-shaped wear-resistant plate 301 is coated with an anti-corrosion coating 303, which effectively resists corrosive environments (such as moisture, chemicals, etc.), prevents the surface of the idler roller from rusting, and further extends the service life of the idler roller. The fixing component 4 ensures that the arc-shaped wear-resistant plate 301 is firmly fixed and prevents loosening through the annular slot 403 and locking screw 404. The connection between the pressure plate 304 and the roller shaft 401 through the locking screw 405 further enhances the stability of the overall structure. At the same time, the disassembly and assembly process is simple and quick. The wear-resistant component 2 includes a wear-resistant sleeve 201 and a wear-resistant protrusion 202, which cooperate with the groove 306 at the lower end of the arc-shaped wear-resistant plate 301 to form a tight wear-resistant structure, thereby improving the overall wear resistance of the idler roller and extending its service life.
