Description

Technical Field

[0001] This utility model relates to a side vertical roller of a conveyor roller table that is easy to assemble and disassemble, and belongs to the technical field of bar production equipment in the metallurgical industry. Background Technology

[0002] In the production of bar and round steel, after rolling, the finished rolled pieces are transported to the cooling bed by the conveyor rollers and skirts after the finishing mill. After cooling on the cooling bed, they are transported to the finishing process. The function of the conveyor rollers is to transport the finished rolled pieces. Its main structure includes a roller frame, chutes welded and fixed to the roller frame, horizontal ground rollers installed on the bottom plate of the chutes, and side roller devices installed vertically on the outside of the roller frame. One end of the ground roller is connected to a motor, and the motor drives the ground roller, which rotates to transport the rolled pieces. The side roller device consists of side rollers, a base, and an oil and gas device. The base of the side roller device has four mounting holes and is fastened to the mounting base plate welded to the roller frame by slender countersunk screws. The lower middle part of the chute side plate has a rectangular hole along the vertical direction. The wheel of the side roller protrudes from the inner surface of the chute side plate and can rotate flexibly. Its function is to contact the finished rolled pieces during transportation and avoid the finished rolled pieces rubbing against the inner surface of the chute side plate, which would cause scratches on the finished surface.

[0003] In rolling production, the side rollers experience wear due to prolonged contact with the transported finished workpieces, resulting in a smaller roller diameter. This can be caused by scratches from friction between the finished workpieces and the inner surface of the chute side plate, or by impurities such as iron oxide scale entering the side roller assembly base, leading to poor roller rotation or jamming. In either of these cases, the side roller assembly needs to be disassembled for wheel replacement or cleaning of the base. However, the conveyor rollers transport red-hot, high-temperature finished workpieces for extended periods. Under the intense heat of the workpieces and the heat conduction of the metal roller frame, the slender countersunk screws securing the side roller assembly base are difficult to remove or cannot be removed at all. This results in difficult, time-consuming, and inefficient replacement operations, leading to prolonged downtime and reduced effective operating rates. To address these disassembly difficulties, the method of on-site disassembly and assembly of the side roller assembly has been changed to welding the side roller assembly base to the roller frame. Each disassembly and assembly requires flame cutting to remove the base, repositioning it during installation, and then welding it again, which also results in time-consuming and inefficient replacement and disassembly. Utility Model Content

[0004] The purpose of this invention is to provide a conveyor side roller that is easy to assemble and disassemble, enabling flexible rotation of the side roller without jamming and quick assembly and disassembly, thus solving the problems existing in the background art.

[0005] The technical solution of this utility model is: A side vertical roller of a conveyor roller table that is easy to assemble and disassemble includes a mounting base plate, a long strip key, countersunk screws, a base, a side vertical roller body, a pad, a pressure plate, hexagonal head bolts, hexagonal nuts, a roller table frame, and a side baffle. The mounting base plate and the side baffle are respectively fixed on the roller table frame. The long strip key is fixed on the base plate by countersunk screws. The side baffle has a roller body notch that matches the side vertical roller body. The side vertical roller body is rotatably connected to the base. The base is fixed between the mounting base plate and the pressure plate by two hexagonal head bolts and hexagonal nuts. A pad is provided between the base and the mounting base plate.

[0006] The pad is provided with an elongated hole, which is engaged with the elongated flat key of the mounting base plate.

[0007] The base is provided with a keyway that mates with the elongated flat key on the mounting base plate.

[0008] One end of each of the two hexagonal head bolts is fixed to the mounting base plate.

[0009] The roller body notch on the side baffle that matches the side vertical roller body is a rectangular notch.

[0010] The width of the rectangular roller notch is smaller than the diameter of the side roller.

[0011] The beneficial effects of this utility model are: by removing the nuts fastened to the pressure plate, the side rollers can be quickly disassembled and assembled, saving time and effort, reducing downtime, improving production efficiency, and ensuring that the side rollers can rotate flexibly without jamming.
