Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and in particular to a device for supporting the cooling steel on a rolling mill line. Background Technology

[0002] During the steel plate production process, due to space constraints, the distance between the conveyor rollers reserved between the roughing mill and the finishing mill is relatively short, resulting in a limited number of cooled steel blocks. This is especially true when rolling extra-long plates, where the number of cooled steel blocks is greatly reduced, which seriously affects the rolling rhythm and production efficiency.

[0003] There is an urgent need to develop a device that can expand the space for cooling steel within a limited distance, increase the quantity of cooling steel, and thus increase steel plate production.

[0004] Therefore, a device is needed that can effectively solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a cooling steel support device for rolling mill lines to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: The lifting device is installed between the roughing mill and the finishing mill, and includes two sets of hydraulic cylinders symmetrically arranged on the left and right sides of the roller table. The output ends of the two hydraulic cylinders on each side are fixedly connected to the longitudinal connecting rod on that side through a connecting arm. Within the corresponding roller table range, a transverse connecting rod is provided between every two adjacent rollers. A support plate is provided on the transverse connecting rod. The transverse connecting rod is fixedly connected to the longitudinal connecting rod. The length of the transverse connecting rod is greater than the length of a single roller in the roller table. The two sets of hydraulic cylinders move up and down, driving the connecting arm, the longitudinal connecting rod, the transverse connecting rod, and the support plate to move up and down together.

[0007] Furthermore, the lifting device also includes columns and a clamping mechanism disposed on the left and right sides of the roller conveyor, with the columns on the same side being offset from the hydraulic cylinder.

[0008] Preferably, the clamping mechanism is sleeved on the middle part of the column and includes a rolling wheel, a connecting member II, and a connecting member III; the connecting member III consists of four pieces forming a frame and is sleeved on the middle part of the column; the base of the rolling wheel is fixedly connected to the connecting member III; the rolling wheel abuts against the column and is symmetrically arranged on both sides of the column; one end of the connecting member II is fixedly connected to the outer side of the connecting member III; the longitudinal connecting rod passes through the connecting member II; and the other end of the connecting member II is fixedly connected to the connecting member I.

[0009] Preferably, the column is an I-beam, the length of the roller axle is greater than the width of the I-beam flange, and the roller axle abuts against the surface of the I-beam flange.

[0010] Preferably, the pallet to be renumbered is T-shaped, the length of the top of the pallet is less than the distance between adjacent rollers, the two sides of the pallet are lower than the middle part in the height direction, and the pallet has a hole in the middle with the diameter matching the outer diameter of the transverse connecting rod.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] When there are too many intermediate slabs on the conveyor roller table between the roughing mill and the finishing mill, the accumulated steel plates are lifted by the cooling steel lifting device, and other steel plates pass through normally. When the number of slabs decreases, the cooling steel lifting device is lowered, and the lowered intermediate slabs enter normal rolling. The number of intermediate slabs on the line can be adjusted by the cooling steel lifting device, thereby improving the steel plate production efficiency. Attached Figure Description

[0018] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] This utility model provides, for example Figures 1 to 4The device shown is a steel cooling support device for a rolling mill, installed between the roughing mill and the finishing mill. It includes two sets of hydraulic cylinders 1 symmetrically arranged on the left and right sides of the roller table, with two hydraulic cylinders 1 on each side. The output end of each hydraulic cylinder 1 is fixedly connected to one end of a connecting arm 7, and the other end of the connecting arm 7 is fixedly connected to a longitudinal connecting rod 4. The connecting arm 7 drives the longitudinal connecting rod 4 to move up and down. The distance between the left and right longitudinal connecting rods 4 is greater than the length of the roller 8 and less than the distance between the left and right hydraulic cylinders 1. A transverse connecting rod 5 is arranged between two adjacent rollers 8. The length of the transverse connecting rod 5 is greater than the length of the roller 8. The transverse connecting rod 5 is connected to the longitudinal connecting rod 4 through a connector I 32. The transverse connecting rod 5 is arranged perpendicular to the longitudinal connecting rod 4. Multiple support plates 6 are provided on the outer circular surface of the transverse connecting rod 5.

[0020] The bottom end of the hydraulic cylinder 1 is mounted on the support frame on the outside of the roller conveyor. The support frame is used to install and fix the hydraulic cylinder 1, so that all the hydraulic cylinders 1 are installed on the same plane. The movable end of the hydraulic cylinder 1 is connected to the connecting arm 7, which is L-shaped. The other end of the connecting arm 7 is used to drive the longitudinal connecting rod 4 to move up and down. While the longitudinal connecting rod 4 moves up and down, it drives the clamping mechanism 3 to move on the column 2. At the same time, the clamping mechanism 3 drives the connecting piece to move. The connecting piece drives the transverse connecting rod 5 to move. The transverse connecting rod 5 drives multiple pallets 6 to lift and lower the steel plate, so that it is removed from the surface of the roller 8 and the steel plate is air-cooled.

[0021] Furthermore, the lifting device also includes columns 2 and a clamping mechanism 3 disposed on the left and right sides of the roller conveyor, with the columns 2 on the same side being staggered from the hydraulic cylinder 1.

[0022] The bottom end of the column 2 and the bottom end of the hydraulic cylinder 1 are located on the same horizontal plane. Both the bottom ends of the column 2 and the bottom ends of the hydraulic cylinder 1 are mounted on an external support frame. The column 2 is used to control the movement path of the clamping mechanism 3 and prevent the clamping mechanism 3 from deviating from the vertical path of the hydraulic cylinder 1 during the vertical movement.

[0023] Furthermore, the clamping mechanism 3 is installed in the middle part of the column 2, including a rolling wheel 31, a connecting piece II 33, and a connecting piece III 34; the connecting piece III 34 consists of four pieces forming a frame and is installed in the middle part of the column 2. The base of the rolling wheel 31 is fixedly connected to the connecting piece III 34, the rolling wheel 31 abuts against the column 2, and is symmetrically arranged on both sides of the column 2; one end of the connecting piece II 33 is fixedly connected to the outside of the connecting piece III 34, the longitudinal connecting rod 4 passes through the connecting piece II 33, and the other end of the connecting piece II 33 is fixedly connected to the connecting piece I 32.

[0024] The connector Ⅲ34 consists of four pieces, forming a frame that runs vertically through the column 2. The frame is then fitted onto the middle part of the column 2. The inside of the frame is connected to a roller 31. The base of the roller 31 is fixedly connected to the connector Ⅲ34. The roller 31 is used to slide on the column 2.

[0025] The frame formed by connector Ⅲ34 is connected to connector Ⅱ33 externally. Connector Ⅱ33 is fixedly connected to the longitudinal connecting rod 4. Therefore, when the longitudinal connecting rod 4 moves, it drives connector Ⅱ33, connector Ⅲ34 and roller 31 to move. At the same time, connector Ⅰ32, connector Ⅱ33, connector Ⅲ34 and roller 31 are used for the installation of transverse connecting rod 5 to avoid the weight of the steel plate affecting the position of transverse connecting rod 5 and to prevent the transverse connecting rod 5 from shifting position during use.

[0026] Furthermore, the column 2 is an I-beam, the length of the axle of the rolling wheel 31 is greater than the width of the I-beam flange, and the axle of the rolling wheel 31 abuts against the surface of the I-beam flange.

[0027] The column 2 is an I-beam. The width of the flange of the I-beam is less than the length of the axle of the roller 31. Therefore, the roller 31 can move on the column 2.

[0028] Furthermore, the pallet 6 to be renumbered is T-shaped in general. The length of the top of the pallet 6 is less than the distance between the adjacent rollers 8. The two sides of the pallet 6 are lower than the middle part in the height direction. The pallet 6 has a hole in the middle, and the hole diameter matches the outer diameter of the transverse connecting rod 5.

[0029] The support plate 6 is installed on the outer circular surface of the transverse connecting rod 5, which is located between two adjacent rollers 8. The support plate 6 is in direct contact with the steel plate. The surface of the support plate 6 is arc-shaped and matches the outer contour of the steel plate. It can stably support the steel billet, reduce the contact area with the steel billet, reduce heat conduction, and promote uniform cooling of the steel billet.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
