Description

Technical Field

[0001] This utility model relates to a device for extending the length of a medium-thick plate cooling bed, belonging to the technical field of steel rolling finishing equipment in the metallurgical industry. Background Technology

[0002] The medium-thick plate cooling bed is located after the straightener, between the input and output roller conveyors. It transports the steel plate from the input roller conveyor to the output roller conveyor, slowly reducing the temperature of the steel plate from a high temperature to below 200℃ during the transport process. The cooling bed consists of rollers spaced 550 / 600mm apart. Each row consists of two long shafts, each driven independently by a motor. This divides the cooling bed into left and right sections, which can operate independently or in conjunction. The rollers are mounted on the long shafts, and the rollers are staggered between rows. The design supports steel plates with a thickness of 5–150 mm, a width of 1550–3350 mm, and a length of 6000–32000 mm.

[0003] In the production process of medium and heavy plates, as products are upgraded, the length of steel plates continues to increase. As a result, the load-bearing capacity of the cooling bed can no longer meet the usage requirements. Some steel companies generally adopt the method of adding segmented shears to increase the throughput length and cut the steel plates in a hot state to meet the usage requirements of the cooling bed. However, segmented shears are expensive, difficult to maintain, and consume a lot of energy. Utility Model Content

[0004] The purpose of this invention is to provide a device for extending the length of a medium-thick plate cooling bed, which can maximize the utilization capacity of the cooling bed, meet the requirements of the continuous increase in the length of steel plates, and solve the problems existing in the background technology.

[0005] The technical solution of this utility model is: A length extension device for a medium-thick plate cooling bed is disclosed. The medium-thick plate cooling bed is located after a straightening machine, between the cooling bed input roller conveyor and the cooling bed output roller conveyor. The cooling bed consists of multiple rows of roller shafts, each row containing two long shafts. Each long shaft is driven independently by a motor-driven roller drive reducer, thus dividing the cooling bed into left and right parts. The two parts can operate independently or in conjunction. The rollers are mounted on the long shafts, and the rollers between rows are staggered. The extension device includes an extension cover plate, idler rollers, positioning brackets, and transition brackets. The extension cover plate is located above the cooling bed roller drive reducer and is mounted on the positioning bracket. The extension cover plate is provided with several evenly arranged idler rollers. The transition brackets are respectively located between the extension cover plate and the cooling bed input roller conveyor and the cooling bed output roller conveyor.

[0006] The extended cover plate is provided with a positioning block that cooperates with the positioning bracket.

[0007] The extended cover plate has several evenly arranged rollers, all of which are driven rollers, and the elevation of their upper roller surfaces is lower than the elevation of the upper surface of the roller disc.

[0008] The transition support is a rectangular frame, and the upper surface of the transition support is lower than the elevation of the upper surface of the roller.

[0009] The transition support is equipped with transition rollers.

[0010] The transition support is inclined.

[0011] The beneficial effects of this utility model are: it enables the cooling bed to exceed the original design load-bearing capacity, increasing the length by 1.7-3.4 meters, while avoiding scratches on the lower surface, ensuring the quality of the lower surface, and achieving good performance.

Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings and examples.

[0014] See attached document Figure 1-2 A length extension device for a medium-thick plate cooling bed is disclosed. The medium-thick plate cooling bed is located after the straightening machine, between the cooling bed input roller conveyor and the cooling bed output roller conveyor. The cooling bed consists of multiple rows of roller shafts, each row containing two long shafts 8. Each long shaft 8 is driven independently by a motor-driven roller drive reducer 6, thus dividing the cooling bed into left and right parts. The two parts can operate independently or in conjunction. Rollers 7 are mounted on the long shafts 8, and the rollers 7 between rows are staggered. The extension device includes an extension cover plate 1, idler rollers 2, positioning brackets 3, and transition brackets 5. The extension cover plate 1 is located above the cooling bed roller drive reducer 6 and is mounted on the positioning bracket 3. Several evenly arranged idler rollers 2 are provided on the extension cover plate 1. The transition brackets 5 are respectively located between the extension cover plate 1 and the cooling bed input roller conveyor and the cooling bed output roller conveyor.

[0015] In this embodiment, refer to the appendix Figure 1-2The medium-thick plate cooling bed is located after the straightener, between the input and output roller conveyors.
