Description

Technical Field

[0001] The utility model relates to the technical field of conveying, in particular to a belt conveyor roller for coal mines. Background Art

[0002] In coal mining, belt conveyors are essential material handling equipment, and their stability and reliability are crucial to the smooth operation of the entire production line. As a key component of belt conveyors, idlers support the conveyor belt and bear the weight of the material, while also reducing friction between the conveyor belt and the drive roller to ensure smooth operation.

[0003] However, in existing belt conveyors used in coal mines, the process of disassembling and assembling rollers is often complicated and tedious. Traditional roller disassembly and assembly methods usually require removing the bearings at both ends of the roller before removing the roller from the conveyor belt. This disassembly and assembly method has obvious disadvantages, mainly manifested in the following aspects:

[0004] The disassembly and assembly process is complicated: the bearing needs to be removed before the roller can be taken out, which increases the difficulty and operation steps of disassembly and assembly, and is not conducive to quick replacement and maintenance.

[0005] Impact on production efficiency: Due to the complexity of the disassembly and assembly process, it requires a lot of manpower and time, resulting in increased production line downtime, affecting the production efficiency of the coal mine.

[0006] Great safety hazard: During the disassembly process, the frequent operation of bearings and rollers may easily cause accidental injuries to operators, increasing safety risks.

[0007] High damage rate: During the disassembly and installation process, bearings and rollers are easily damaged, which increases the maintenance cost of the equipment and shortens its service life.

[0008] In view of the above problems, the utility model proposes a roller for a belt conveyor for coal mines that is easy to disassemble and assemble, aiming to simplify the disassembly and assembly process of the roller, improve production efficiency and safety, and reduce equipment maintenance costs and shorten service life. Utility Model Content

[0009] In order to solve the above problems, the utility model designs a belt conveyor roller for coal mines.

[0010] In order to achieve the above technical objectives and the above technical effects, the present invention is implemented through the following technical solutions:

[0011] A belt conveyor roller for coal mines, comprising a roller, wherein a plurality of screw holes are provided on both left and right side walls of the roller;

[0012] A round rod, wherein a fixing plate is provided on the inner end wall of the round rod, a plurality of through holes are formed on the outer wall of the fixing plate, a cylinder is provided on the outer end wall of the round rod, a clamping block is provided on the outer end wall of the cylinder, a bolt is movably inserted through the through hole, and the inner end of the bolt is threaded into the screw hole;

[0013] It also includes a bearing seat, in which a connecting rod is rotatably connected, an inner end surface of the connecting rod is provided with a slot, an outer wall of the connecting rod is threadedly connected to a rotating cylinder, and an outer wall of the rotating cylinder is provided with a plurality of protrusions.

[0014] Furthermore, the number of the screw holes and the through holes are equal, and their positions are relatively arranged.

[0015] Furthermore, an outer ring of a bearing is provided on the inner wall of the bearing seat, and the inner ring of the bearing is connected to the outer wall of the connecting rod by interference fit.

[0016] Furthermore, threads are provided on the outer walls of the cylinder and the connecting rod, and are connected to the rotating cylinder in a threaded matching manner.

[0017] Furthermore, a plurality of the protrusions are arranged on the outer wall of the drum with circumferential gaps.

[0018] The beneficial effects of the utility model are:

[0019] The utility model adopts a roller disassembly and assembly method without disassembling the bearing, which can greatly reduce the operation steps and reduce the difficulty of disassembly and assembly, making maintenance and replacement work faster and more convenient, which will help reduce the downtime of the production line and improve production efficiency;

[0020] The simplified disassembly and assembly process reduces labor and equipment investment, thereby reducing maintenance costs. At the same time, since the bearings do not need to be disassembled frequently, the bearing damage rate is also reduced, further reducing maintenance costs. The simplified disassembly and assembly process reduces the frequency of contact between operators and equipment, reduces operational risks, and thus improves work safety. The simplified disassembly and assembly process reduces the risk of equipment failure and performance degradation caused by improper disassembly and assembly, thereby improving equipment reliability and stability.

[0021] By simplifying the assembly and disassembly process of rollers, the entire production process can be optimized and the overall efficiency and flexibility of the production line can be improved, which is of great significance for coping with various changes and challenges in the production process.
