Description

Technical Field

[0001] The present application belongs to the technical field of roller cooling beds, and in particular relates to a roller cooling bed. Background Art

[0002] Roller cooling beds have been widely used in medium and thick plate production lines. The roller cooling beds currently used have rollers for supporting and positioning each section of the long roller shaft. The long roller shaft is placed on the rollers without constraints. Each section of the shaft has about 2 to 3 fulcrums (the number is determined by the spacing of the fulcrums), and each fulcrum is supported by two rollers and a tray. The purpose of this support method is to keep the bearing points as far away from the heat radiation area as possible.

[0003] After recent use, it is found that the existing roller cooling bed is difficult to install, has a high failure rate and high operation and maintenance costs. The slight processing or installation errors of the existing roller cooling bed can easily cause part of the pallet to be suspended or in single-sided contact with the roller, thereby increasing the wear rate of the pallet and roller, reducing the service life of the equipment and increasing the operating cost. At the same time, it also destroys the flatness of the roller cooling bed surface. This has also become a major reason for the deviation of the steel plate. It is found that the support method of the existing roller cooling bed cannot effectively reduce the working temperature of the bearing. The existing roller cooling bed can only keep the distance between the roller bearing point and the hot steel plate at a maximum of about 450mm. Due to its structure, it is impossible to insulate the roller bearing. Therefore, in terms of its high operating cost and difficulty in installation and maintenance, the roller cooling bed of this structural form designed for the purpose of keeping the bearing away from the strong heat radiation area and reducing the bearing temperature is no longer the best choice. The axial movement of the existing roller cooling bed is positioned by the groove wheel, which cannot solve the "biting edge" phenomenon of the supporting pallet. Summary of the invention

[0004] The purpose of the present application is to provide a roller cooling bed, aiming to solve the technical problem of easy wear on the edge of the roller cooling bed at least to a certain extent.

[0008] In some embodiments, a first heat insulation cover is disposed on both the first fixed bearing seat and the first movable bearing seat.

[0009] In some embodiments, the first roller shaft includes two first shaft bodies, and the two first shaft bodies are connected by a first connecting unit.

[0010] In some embodiments, the first connection unit includes: an intermediate shaft and two sleeves, and two ends of the intermediate shaft are respectively connected to the two first shaft bodies through the sleeves.
