Description

Technical Field

[0001] The invention belongs to the technical field of metallurgical equipment and relates to a guide device for preventing a belt from deviating. Background Art

[0002] Today, with the increasing output of strip steel in the steel rolling field, users not only have higher and higher requirements for the mechanical properties of products, but also have put forward new requirements for the surface quality of products. Belt winding equipment and belt conveyor equipment are auxiliary equipment in the production of strip materials in steel rolling projects. Whether they can work normally will directly affect the operation of the entire system. The belt plays a key role in it. It is necessary to adjust the position of the roller to achieve the tensioning function. At the same time, to prevent the belt from running off, the roller is usually made into a special roller with an outer convexity. However, during use, the belt will deform, stretch and become loose, and the tension is insufficient, causing the belt to run off. Belt deviation often occurs during the operation of the equipment. There are many reasons for the belt deviation, mainly caused by installation and operation. Belt deviation can cause system failures and affect production efficiency; it can damage the main components of the equipment; it is easy to form safety hazards and other problems.

[0003] Therefore, it is particularly important to ensure the reliable operation of belt winding equipment and belt transportation equipment. Summary of the invention

[0004] The purpose of the present invention is to provide a guide device for preventing the belt from deviation, which can effectively solve the problem that after the belt has been running for a period of time, the belt is stretched to produce permanent deformation or aging, and the tension of the belt decreases, causing the belt to loosen and deviate. It can also solve the problem that the belt is deviated due to vibration during operation. The mechanical vibration of the belt conveyor during operation is inevitable. The faster the belt conveyor runs, the greater the vibration, and the greater the belt deviation.

[0005] The technical solution adopted by the present invention is: a guiding device for preventing the belt from running off track, including a tensioning roller device for tensioning the belt, and vertical guide roller devices are symmetrically arranged on both sides of the belt. The vertical guide roller devices are fixed on a frame to limit the two sides of the belt to prevent running off track.

[0006] The present invention is also characterized in that:

[0007] The tensioning roller device comprises a roller, a belt is wound around the roller, and both ends of the roller are fixed on the bearing seat through bearings b; a blind cover is arranged on the outer side of the bearing seat away from the roller, and a transparent cover is arranged on the inner side of the bearing seat close to the roller.

[0008] A distance sleeve b is arranged in the inner ring of the bearing b to carry out axial positioning of the roller.

[0009] The roller body is concave, gradually concave 10-15mm from the edge of the roller body to the middle.

[0010] The vertical guide roller device includes a shaft, on which rollers are installed through two sets of upper and lower bearings a. The bearings a are installed on the shaft, positioned and connected through a distance sleeve a, and the shaft is axially positioned through a pressure plate and a baffle, and the whole is installed on a bracket.

[0011] The two sets of bearings a are positioned and connected via a distance sleeve a.

[0012] The upper end of the shaft is axially positioned by a pressure plate and a baffle fixed on the bracket, and the lower end of the shaft is fixedly mounted on the bracket, and the bracket is fixed on the side of the belt frame body.

[0013] A screw hole pad is welded on the side of the belt frame body, and the bracket is fixed to the side of the belt frame body through the screw hole pad. A gasket group is also arranged between the screw hole pad and the bracket. The gasket group consists of several detachable gaskets. The gap between the vertical guide roller device and the belt is adjusted by adding or deleting gaskets to prevent the belt from deviating.

[0014] The beneficial effects of the present invention are as follows: vertical guide roller devices are added on both sides of the belt width direction, and bearings are installed inside the vertical guide roller devices. If the belt deviates during operation, the vertical rollers will block the belt to prevent it from deviating. On the other hand, the belt is moving, and there is rolling friction between the rollers and the belt, which will not cause much wear on the belt edge. This not only prevents the belt from deviating, but also reduces belt wear and increases the service life of the belt. When used in combination with a concave tensioning roller, it can effectively prevent the belt from deviating. BRIEF DESCRIPTION OF THE DRAWINGS
