Description

Technical Field

[0001] The utility model belongs to the technical field of transmission and conveying, and relates to a conveyor, in particular to a conveyor roller. Background Art

[0002] The roller is one of the important components of the conveyor. It is mounted on both ends of the belt and drives the conveyor belt by rotating the driving roller.

[0003] During the coal transportation work at the port, the environment is relatively harsh, and coal blocks will inevitably fall on the rollers, causing wear and tear on the rollers. In order to ensure the normal operation of the conveyor, the rollers need to be regularly repaired and replaced, which not only consumes manpower and material resources, but also affects the coal transportation efficiency of the port. Utility Model Content

[0004] The utility model aims to provide a conveyor roller with a scientific and reasonable structural design, which saves manpower and effort, reduces maintenance costs, improves work efficiency, prolongs service life, and is easy to implement.

[0005] The utility model solves the technical problem through the following technical solutions:

[0006] A conveyor roller comprises a roller body, characterized in that the outer surface of the roller body is covered with wear-resistant tiles by screws.

[0007] Moreover, the wear-resistant tiles include an upper pressure tile and a lower pressure tile that fit the curvature of the roller body. A first beveled edge inclined inward from top to bottom is cut at both ends of the upper pressure tile, and a second beveled edge inclined outward from top to bottom is cut at both ends of the lower pressure tile. The inclination of the first beveled edge is the same as that of the second beveled edge. First connecting holes are evenly spaced at both ends of the upper pressure tile, and a first screw connected to the roller body is provided in the first connecting hole.

[0008] Moreover, the included angle between the first bevel and the upper end surface of the upper pressing tile is 15-60 degrees.

[0009] Moreover, the wear-resistant tile comprises a wear-resistant metal material, and a wear-resistant block material is inlaid on the wear-resistant metal material.

[0010] Moreover, the wear-resistant tile comprises a wear-resistant metal material, a glue injection layer is arranged on the surface of the wear-resistant metal material, and a wear-resistant block material is inlaid on the glue injection layer.

[0011] The advantages and beneficial effects of the utility model are:

[0012] 1. This conveyor roller, by covering the outside of the existing roller body with spliced ​​wear-resistant tiles, facilitates the repair of the roller after damage, that is, just replace the corresponding wear-resistant tiles, which is simple and convenient, reducing the cumbersome operation and replacement cost of replacing the entire roller.

[0013] 2. The conveyor roller is designed with wear-resistant tiles as upper and lower pressure tiles that fit the curvature of the roller body, and the chamfers at both ends of the upper pressure tile are used to press the chamfers at both ends of the lower pressure tile. The upper pressure tile is fixed by the first screw. During operation, only the first screw on the upper pressure tile needs to be installed, which not only improves installation efficiency but also reduces the use of screws.

[0014] 3. The utility model has a scientific and reasonable design, and has the advantages of saving manpower and labor, reducing maintenance costs, improving work efficiency, extending service life, and being easy to implement. It is a conveyor roller with high innovation. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention will be further described in detail below through specific embodiments. The following embodiments are merely descriptive and not restrictive, and the protection scope of the present invention cannot be limited by them.

[0023] A conveyor roller comprises a roller body 1, which comprises a mounting shaft 5 and a cylinder body 4 mounted on the mounting shaft. The innovation thereof lies in that mounting holes are provided at both axial ends of the roller body, and the outer surface of the roller body is covered with wear-resistant tiles 3, which are connected to the mounting holes on the cylinder body through first screws 2.

[0024] In order to improve the installation efficiency of the wear-resistant tiles and reduce the use and operation of screws, the wear-resistant tiles include an upper pressure tile 7 and a lower pressure tile 6 that fit the curvature of the roller body. Both ends of the upper pressure tile and the lower pressure tile are provided with chamfered structures, that is, a first beveled edge inclined inward from top to bottom is cut at both ends of the upper pressure tile, and a second beveled edge inclined outward from top to bottom is cut at both ends of the lower pressure tile. The inclination of the first beveled edge is the same as that of the second beveled edge. First connecting holes are evenly spaced at both ends of the upper pressure tile, and a first screw connected to the roller body is provided in the first connecting hole, and the nut of the screw is embedded in the connecting hole.

[0025] In order to ensure the crimping stability of the upper pressure tile to the lower pressure tile, the angle between the first bevel and the upper end surface of the upper pressure tile is 15-30 degrees, so that the two ends of the upper pressure tile are crimped on the two ends of the lower pressure tile, thereby eliminating the operation of fixing the lower pressure tile with screws.

[0026] The wear-resistant tile comprises a wear-resistant metal material, on which a wear-resistant block material is inlaid.

[0027] The wear-resistant tile comprises a wear-resistant metal material, a glue injection layer is arranged on the surface of the wear-resistant metal material, and a wear-resistant block material is inlaid on the glue injection layer.

[0028] The wear-resistant metal material is an iron-carbon alloy, and the wear-resistant block material is a ceramic material.

[0029] In this embodiment, there are 6 wear-resistant tiles, including 3 upper pressure tiles and 3 lower pressure tiles. Three evenly spaced connecting holes are provided at both ends of the upper pressure tiles for connecting to the drum body through the first screw. The thickness of each wear-resistant tile is 14 mm.

[0030] like Figure 5 As shown, in order to further ensure the stability of the downward pressing tile, in specific operations, second screws 8 can also be set at both ends of the downward pressing tile to reinforce the connection to the cylinder body through the second screws.

[0031] Although the embodiments and drawings of the present invention are disclosed for illustrative purposes, those skilled in the art will appreciate that various substitutions, changes and modifications are possible without departing from the spirit and scope of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
