Description
Technical Field
[0001] This utility model relates to the technical field of continuous casting roll disassembly devices, and specifically to a continuous casting roll disassembly device. Background Technology
[0002] The original method for disassembling the curved section roller: After disassembling the bearing seats at both the fixed and free ends, fix the D-type shackle c onto the continuous casting roll mandrel b. Use a crane to vertically lift the continuous casting roll mandrel b, and disassemble it using the weight of the continuous casting roll sleeve a itself. Figure 1 As shown.
[0003] Problems with disassembling the original bending section rollers: 1. During the disassembly process, the continuous casting rolls lifted by the overhead crane may sway back and forth, which may cause the rolls to hit people and lead to lifting accidents; 2. During the disassembly process, the roller sleeve may get stuck on the continuous casting roll mandrel b due to uneven force during its descent, making it impossible to disassemble normally. It is necessary to manually knock the roller sleeve off the continuous casting roll mandrel b, resulting in low disassembly efficiency of the continuous casting roll. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a continuous casting roll disassembly device, which aims to solve the problems of low disassembly efficiency and easy injury caused by the existing continuous casting roll disassembly.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A continuous casting roll dismantling device, comprising: Workbench; A baffle is fixedly connected to the top of the worktable. The baffle is provided with a clearance opening for the continuous casting roll mandrel to pass through. The size of the clearance opening is smaller than the outer diameter of the continuous casting roll sleeve. The first support assembly is fixedly connected above the worktable and located on one side of the baffle, and is used to support the continuous casting roll sleeve; The second support assembly is fixedly connected above the worktable and located on the side of the baffle away from the first support assembly, and is used to support the continuous casting roll mandrel; The drive assembly is fixedly connected above the worktable and located on the side of the first support assembly away from the baffle. It is used to drive the continuous casting roll mandrel to pass through the baffle along the length of the worktable and slide onto the second support assembly.
[0006] Furthermore, the first support assembly consists of multiple sets of first support blocks spaced apart along the length of the worktable. Each set of first support blocks is provided with a first arc-shaped groove for matching the continuous casting roll sleeve. The continuous casting roll sleeve and the first arc-shaped groove are slidably connected along the axial direction of the continuous casting roll.
[0007] Furthermore, the second support assembly consists of multiple sets of second support blocks spaced apart along the length of the worktable. Each set of second support blocks is provided with a second arc-shaped groove for matching the continuous casting roll mandrel. The continuous casting roll mandrel and the second arc-shaped groove are slidably connected along the axial direction of the continuous casting roll.
[0008] Furthermore, multiple sets of the first support assembly and the second support assembly are provided at intervals along the width direction of the worktable.
[0009] Furthermore, the driving component is a cylinder, the piston rod axis of the cylinder is distributed along the length direction of the worktable, and the outer diameter of the piston rod end near the continuous casting is smaller than the outer diameter of the continuous casting roll mandrel.
[0010] Furthermore, a first bulletproof component and a second bulletproof component are respectively provided above the workbench to prevent the continuous casting roll sleeve and the continuous casting roll mandrel from springing up.
[0011] Furthermore, both the first bulletproof component and the second bulletproof component consist of a fixed post and a bulletproof rod detachably fixedly connected above the fixed post. The length of the bulletproof rod is distributed along a direction perpendicular to the axis of the continuous casting roll, and the bulletproof rods of the first bulletproof component and the second bulletproof component are located above the continuous casting roll sleeve and the continuous casting roll mandrel, respectively.
[0012] Furthermore, multiple sets of fixed posts are arranged at intervals along the length of the workbench, and the bulletproof rod is fixedly connected to the fixed posts by bolts.
[0013] Furthermore, a limiting plate is fixedly connected above the workbench, and the limiting plate is located at one end of the workbench along its length, closer to the second support component.
[0014] The technical solution provided by this utility model has the following advantages compared with the prior art: 1. The device is equipped with a baffle, a first support assembly, a second support assembly, and a drive assembly. The drive assembly moves the continuous casting roll mandrel, the continuous casting roll sleeve is isolated on one side by the baffle, and the continuous casting roll mandrel slides onto the second support assembly. When the continuous casting roll is disassembled, it can be placed horizontally above the worktable. Compared with the existing technology that uses a crane to disassemble, this avoids the risk of injury caused by the continuous casting roll swaying back and forth. 2. During the disassembly of the continuous casting roll using this device, the continuous casting roll mandrel is subjected to uniform force and will not jam with the continuous casting roll sleeve. There is no need to use manpower or external force to strike the continuous casting roll sleeve, thus avoiding damage to the continuous casting roll bearing seat during conventional disassembly and improving work efficiency. 3. By setting up the first bulletproof component and the second bulletproof component, the continuous casting roll sleeve and the continuous casting roll mandrel can be prevented from jumping up and injuring people during disassembly. 4. By setting a limiting plate at the end of the worktable, the continuous casting roll mandrel can be blocked to prevent it from sliding out to the outside of the worktable after it completely detaches from the continuous casting roll sleeve. 5. Multiple sets of fixing posts in the bulletproof assembly are arranged at intervals along the length of the worktable, i.e., the axial direction of the continuous casting roll. The position of the bulletproof rod can be set according to the actual size of the continuous casting roll, which is suitable for disassembly of different models of continuous casting rolls.

Detailed Implementation
[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0018] like Figures 2-3As shown, this utility model provides a continuous casting roll disassembly device, including a worktable 1, a baffle 2, a first support component, a second support component, and a drive component. The baffle 2 is fixedly connected to the middle position of the upper end of the worktable 1. The first support component and the second support component are respectively located on the left and right sides of the baffle 2. The drive component is set on the upper end of the worktable 1 near the first support component.
[0019] Specifically, the workbench 1 consists of legs 101 and a support plate 102. The support plate 102 is fixedly connected above the legs 101 and its length is distributed along the left and right directions.
[0020] The baffle 2 has a rectangular plate structure, and its length is distributed along the front-to-back direction, i.e. the width direction of the support plate 102. The lower end face of the baffle 2 is provided with a left-to-right through clearance opening 201. The clearance opening 201 is larger than the continuous casting roll mandrel b and smaller than the continuous casting roll sleeve a, i.e., only the continuous casting roll mandrel b can pass through from the left and right.
[0021] The first support assembly consists of multiple sets of first support blocks 3 located on the right side of the baffle 2. The multiple sets of first support blocks 3 are spaced apart in the left-right direction. The first support blocks 3 are as follows: Figure 2 As shown, it is fixedly connected to the upper end face of the support plate 102, and a recessed first arc groove 301 is provided at its upper end. The shape and size of the first arc groove 301 match the continuous casting roll sleeve a. After the continuous casting roll sleeve a is placed above multiple sets of first support blocks 3, it can slide left and right along the first arc groove 301.
[0022] The second support assembly consists of multiple sets of second support blocks 4 located on the left side of the baffle 2. Similarly, the multiple sets of second support blocks 4 are distributed at intervals in the left and right direction. The second support blocks 4 are fixedly connected to the upper end face of the support plate 102. A recessed second arc-shaped groove is provided at the upper end of the second arc-shaped groove. The shape and size of the second arc-shaped groove match the continuous casting roll mandrel b. When the continuous casting roll mandrel b is placed above the second support block 4, the continuous casting roll mandrel b can slide left and right along the second arc-shaped groove.
[0023] By setting the first support component and the second support component, the continuous casting roll sleeve a and the continuous casting roll mandrel b are supported and guided respectively. It should be noted that the position of the second arc groove of the second support block 4 in the height direction is consistent with the position of the continuous casting roll mandrel b when it is not detached from the continuous casting roll sleeve a, so that the continuous casting roll mandrel b can slide smoothly into the second arc groove after it is detached.
[0024] Furthermore, in order to improve the stability of the first support block 3 and the second support block 4, fixing rods are provided on the upper end face of the support plate 102 on both the left and right sides of the baffle 2. The length of the fixing rods is distributed along the left and right direction. The lower end face of the first support block 3 and the second support block 4 is provided with upper grooves that cooperate with the fixing rods. When installing and fixing, the first support block 3 and the second support block 4 are snapped onto the fixing rods and welded to fix them.
[0025] The drive assembly includes a cylinder 10, which is driven by an air tank 11 and an air supply line connected to the two. This part is common knowledge and will not be described in detail. The cylinder 10 is located at the right end of the support plate 102. The cylinder body of the cylinder 10 is fixedly connected to the support plate 102. The piston rod axis of the cylinder 10 is horizontally distributed in the left and right direction, and the movable end of the left end of the piston rod corresponds to the position of the continuous casting roll mandrel b. Its size is slightly smaller than that of the continuous casting roll mandrel b. When the cylinder 10 is activated, the left end of the piston rod will contact the continuous casting roll mandrel b. When the continuous casting roll sleeve a contacts the right side of the baffle 2, the left end of the piston rod continues to drive the continuous casting roll mandrel b to move to the left and pass through the clearance opening 201 before falling into the second arc-shaped groove of the second guide block 4.
[0026] In this embodiment, the first support assembly and the second support assembly are arranged in multiple sets along the front-back direction, i.e., the width direction of the support plate 102. The cylinder 10 is also arranged in multiple sets along the front-back direction. Each set of cylinder 10 corresponds to a set of continuous casting rolls, so that multiple sets of continuous casting rolls can be disassembled at the same time to improve work efficiency.
[0027] To prevent the ends of the continuous casting roll sleeve a and the continuous casting roll mandrel b from springing up during disassembly, this device is also equipped with a first bulletproof component 5 and a second bulletproof component 6. The first bulletproof component 5 and the second bulletproof component 6 are located on the right and left sides above the support plate 102, respectively, and both consist of fixed posts 7 and bulletproof rods 8. Two sets of fixed posts 7 are provided, located on the front and rear sides above the support plate 102, respectively. The upper end of the fixed post 7 is provided with a threaded hole. The length of the bulletproof rod 8 is horizontally distributed along the direction perpendicular to the axis of the continuous casting roll, and both ends of the length direction are provided with threaded holes that pass through vertically and correspond to the positions of the threaded holes on the fixed posts 7. The bulletproof rod 8 is detachably fixed to the two fixed posts 7 by bolts, and its vertical position can be adjusted to a certain extent; moreover, the bulletproof rod 8 of the first bulletproof component 5 The distance in the height direction between the continuous casting roll sleeve a and the first arc groove 301 is slightly larger than the outer diameter of the continuous casting roll sleeve a. That is, when the continuous casting roll sleeve a is located in the first arc groove 301, the gap between the lower end of the bulletproof rod 8 of the first bulletproof component 5 and the upper end of the continuous casting roll sleeve a is distributed. The distance in the height direction between the bulletproof rod 8 of the second bulletproof component 6 and the second arc groove is slightly larger than the outer diameter of the continuous casting roll mandrel b. That is, when the continuous casting roll mandrel b is located in the second arc groove, the gap between the lower end of the bulletproof rod 8 of the second bulletproof component 6 and the upper end of the continuous casting roll mandrel b is distributed. By setting the first bulletproof component 5, the end of the continuous casting roll sleeve a can be prevented from jumping up and injuring people during the process of the cylinder 10 pushing out the continuous casting roll mandrel b. The second bulletproof component 6 can be prevented from jumping up and injuring people during the process of the continuous casting roll mandrel b moving to the left.
[0028] Furthermore, in this embodiment, both the first bulletproof component 5 and the second bulletproof component 6 are provided with multiple mounting positions for bulletproof rods 8 along the length of the support plate 102, such as... Figure 2As shown, multiple sets of fixing components are distributed at intervals from right to left. Each set of fixing components consists of two sets of fixing columns 7 that are fixedly connected to the front and rear sides of the support plate 102 respectively. With this setting, the position of the bulletproof rod 8 in the left and right directions can be adaptively adjusted according to the size of the continuous casting roll sleeve a and the continuous casting roll mandrel b.
[0029] In addition, in this embodiment, a limiting plate 9 is fixedly connected to the upper left end of the support plate 102. The limiting plate 9 consists of two parts: a vertical plate perpendicular to the support plate 102 and an inclined plate inclined to the right. By setting the limiting plate 9, the continuous casting roll mandrel b can be prevented from popping out to the outside of the worktable 1. Of course, in order to reduce the hard impact between the continuous casting roll mandrel b and the limiting plate 9, the inner side of the limiting plate 9 is... Figure 2 An elastic buffer layer, such as a rubber layer, can also be provided on the right side shown.
[0030] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
