Description

Technical Field

[0001] The invention relates to a belt conveyor roller structure and belongs to the technical field of raw material conveying equipment in the metallurgical industry. Background Art

[0002] In the metallurgical industry, various minerals required for smelting are conveyed to blast furnaces and sintering machines via belt conveyors. Belt conveyors rely on conveyor rollers to drive the belts. After a period of use, conveyor rollers wear out to the point where they become unusable and need to be replaced. Some conveyor rollers are located in confined spaces without access to lifting equipment. Replacing the conveyor rollers also requires replacing the bearing housings, which is time-consuming and labor-intensive. Replacing a single conveyor roller requires five people, making it labor-intensive and time-consuming. Summary of the Invention

[0006] Pull rings are respectively provided at both ends of the guide rail in the middle of the arc wear-resistant plate and matched with the guide groove.

[0007] The cross section of the guide rail in the middle of the arc wear-resistant plate that matches the guide groove is triangular.

[0008] The clearance between the guide rail in the middle of the arc wear-resistant plate and the guide groove in the circumferential direction of the roller body is 0.1 mm.

[0009] Both ends of the arc wear-resistant plate match with the clamping grooves provided in the circumferential direction of the roller body.

[0010] The roller body is fixed on the roller body shaft through two groups of roller body surface support rods, and each group of roller body surface support rods consists of four rods evenly arranged along the circumferential direction of the roller body shaft.

[0011] The beneficial effects of the present invention are: the belt conveyor roller structure is easy to assemble and disassemble, can be quickly replaced, saves manpower, reduces maintenance time, is simple to operate, has good wear resistance and long service life.

Implementation Method

[0017] The present invention will be further described below with reference to the accompanying drawings and through examples.

[0018] Refer to the attached Figure 1-4 , a belt conveyor roller structure, comprising a roller shaft 4, a roller surface support rod 5, an arc wear-resistant plate 6 and a roller body 10. The roller body 10 is a hollow cylindrical structure, and the roller body 10 is fixed to the roller shaft 4 by a number of stick surface support rods 5. Four card slots 1 and four guide grooves 3 are provided in the circumferential direction of the roller body 10. The four card slots 1 and the four guide grooves 3 are arranged at intervals, and each card slot 1 is provided with a roller fixing screw hole 2; the arc wear-resistant plate 6 is a quarter arc plate that matches the roller body 10, and the two ends of the arc wear-resistant plate 6 are respectively provided with arc wear-resistant plate fixing screw holes 9 that match the roller fixing screw holes 2, and the middle of the arc wear-resistant plate 6 is provided with a guide rail 7 that matches the guide groove 3; the four arc wear-resistant plates 6 are respectively fixed to the outer surface of the roller body 10 by bolts.

[0019] In this embodiment, refer to the attached Figure 1 、 2 Roller 10 is a symmetrical, hollow circle with a surface thickness of 3 cm to achieve lightweight construction. Supported by eight surface support rods 5, four rods are welded to the roller shaft 4 and the roller 10 surface. Four roller fixing screw holes 2 are positioned at the same end, 5 cm from the center of the roller 10. This facilitates bolt fastening of the arc-shaped wear-resistant plate 6 to the roller 10. One end of the roller shaft 4 is fixed to the motor, and the other end is fixed to the bearing seat. Four retaining slots 1 and four guide slots 3 are arranged at intervals on the roller 10.

[0020] Refer to the attached Figure 3 、 4 There are four arc wear-resistant plates 6, which can cover the surface of the roller body 10. The inner diameter of the circle formed by the four arc wear-resistant plates 6 is consistent with the outer diameter of the roller body 10, with an error of 0.1mm. The two ends of the arc wear-resistant plates 6 can be inserted into the slots 1 on the roller body 10, with a clearance fit of 0.1mm. The guide rail 7 and the guide groove 3 have a clearance fit of 0.1mm. The pull ring 8 is a steel pull ring. The two pull rings 8 are welded to the guide rail 7 respectively. Its strength meets the pulling requirements. The length of the pull ring 8 is shorter than the length of the arc wear-resistant plate 6. The fixing screw hole 9 of the arc wear-resistant plate must coincide with the fixing screw hole 2 of the roller body, and the size and model are consistent so that the bolts can be tightened together.

[0021] Refer to the attached Figure 1-4 , the working principle is as follows:

[0022] The roller body 10 and the arc wear-resistant plate 6 are connected together by clearance fit and bolt connection. When disassembling, first unscrew the bolts, then pull the pull ring 8 with a wire rope to pull out the worn arc wear-resistant plate 6 from one side of the roller body 10, and then insert the new arc wear-resistant plate 6 into the roller body 10, and pull the pull ring 8 with a wire rope to the position where the roller body fixing bolt hole 2 and the arc wear-resistant plate fixing screw hole 9 coincide, and tighten the bolts. This method can be operated by two people, saving manpower, time, and the cost of replacing the entire belt conveyor roller, greatly increasing work efficiency.
