Technical Field

[0001] This utility model relates to the field of cooling bed technology, and in particular to a closed-loop running groove mechanism on a cooling bed. Background Technology

[0002] The cooling bed is a key piece of equipment in the metallurgical industry used for cooling, conveying and finishing rolled steel pipes, bars and profiles. It is usually located after the rolling mill and before the finishing process, and is an important link connecting hot rolling and subsequent processing.

[0003] Traditional troughing mechanisms are typically open structures, which generate a large amount of dust that is released into the surrounding environment during the conveying of rolled parts. This can pollute the working environment and affect the health of operators. Summary of the Invention

The cooling bed body is provided with a running groove, which is adapted to the stepping rack of the cooling bed body. Three sets of L-shaped connecting rods are provided on the outer side of the stepping racks at both ends of the cooling bed body. Rollers are provided on the L-shaped connecting rods. Three sets of side grooves are opened on both sides of the outer wall of the cooling bed body, and springs are fixedly installed in the side grooves. The cover plate has grooves at both ends of its bottom surface, and the rollers roll within the grooves. The bottom of the cover plate is fixedly connected to a spring.

[0006] In addition, a preferred structure is that three T-shaped sliding rods are fixedly installed at both ends of the top of the cooling bed body.

[0007] In addition, a preferred structure is that both ends of the cover plate are provided with sliding holes, and the cover plate is sleeved on the T-shaped sliding rod through the sliding holes.

[0008] In addition, a preferred structure is that several slots are provided on both sides of the inner wall of the cooling bed body, and a T-shaped limiting groove is provided at the outer end of the slot, and the slot and the T-shaped limiting groove are connected.

[0009] In addition, a preferred structure is that both ends of the slot are provided with limit strips, which are vertically inserted into the slot.

[0010] In addition, a preferred structure is that a T-shaped limiting block is installed in the T-shaped limiting groove by screws, and the bottom of the T-shaped limiting block is in close contact with the top of the limiting strip.

[0011] The beneficial effects of this utility model are as follows: In this invention, during the conveying process of the rolled piece, the rolled piece is located between the trough and the cover plate. The cover plate reduces the spillage of dust, thereby reducing environmental pollution and protecting the health of the workers. Attached Figure Description

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figure 1-7 The closed-loop running groove mechanism on the cooling bed includes a cooling bed body 1 and a cover plate 2. A running groove 4 is provided inside the cooling bed body 1. The running groove 4 is adapted to the stepping rack of the cooling bed body 1. Three sets of L-shaped connecting rods 7 are provided on the outer side of the stepping racks at both ends of the cooling bed body 1. Rollers 8 are provided on the L-shaped connecting rods 7. Three sets of side grooves 11 are opened on both sides of the outer wall of the cooling bed body 1. Springs 3 are fixedly installed in the side grooves 11. The cover plate 2 has grooves 22 at both ends of its bottom surface, and the roller 8 rolls within the grooves 22. The bottom of the cover plate 2 is fixedly connected to the spring 3.

[0016] Meanwhile, three T-shaped slide bars 5 are fixedly installed at both ends of the top of the cooling bed body 1.

[0017] Furthermore, both ends of the cover plate 2 are provided with sliding holes 21. The cover plate 2 is fitted onto the T-shaped sliding rod 5 through the sliding holes 21, and the T-shaped sliding rod 5 guides the up and down movement of the cover plate 2.

[0018] Meanwhile, several slots 12 are provided on both sides of the inner wall of the cooling bed body 1, and a T-shaped limiting groove 13 is provided at the outer end of the slot 12, and the slot 12 is connected to the T-shaped limiting groove 13.

[0019] Meanwhile, limit inserts 41 are provided at both ends of the slot 4. The limit inserts 41 are vertically inserted into the slot 12 to limit the position of the slot 4.

[0020] Furthermore, a T-shaped limiting block 6 is installed in the T-shaped limiting groove 13 by screws. The bottom of the T-shaped limiting block 6 is in close contact with the top of the limiting insert 41. The T-shaped limiting block 6 can be removed from the T-shaped limiting groove 13 to replace the running groove 4.

[0021] In this embodiment, the stepping rack of the cooling bed body 1 starts to move, thereby driving the L-shaped connecting rod 7 to move synchronously. The L-shaped connecting rod 7 moves upward in a circle, thereby causing the roller 8 to roll in the groove 22. The roller 8 pushes the cover plate 2 upward in the groove 22. At this time, the spring 3 is stretched. Then the stepping rack starts to transport the rolled piece. When the rolled piece enters the next running groove 4, the stepping rack starts to reset in a circle. The L-shaped connecting rod 7 moves downward in a circle, thereby causing the roller 8 to reset and roll in the groove 22. The cover plate 2 slowly descends and resets under the elastic action of the spring 3, thereby reducing the overflow of dust from the rolled piece. When it is necessary to replace the slot 4, remove the screws, then pull the slot 4 upwards and pull the limiting strip 41 out of the slot 12 to remove the slot 4. Then replace it with a new slot 4, align the limiting strip 41 of the new slot 4 with the slot 12 and insert it. Then use screws to install the T-shaped limiting block 6 into the T-shaped limiting groove 13.

[0022] In this invention, during the conveying process of the rolled piece, the rolled piece is located between the running trough 4 and the cover plate 2. The cover plate 2 reduces the spillage of dust, thereby reducing environmental pollution and protecting the health of the workers.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
