Description

Technical Field

[0001] The utility model relates to the technical field of roller tooling, in particular to a roller guard plate disassembly and assembly support frame. Background Art

[0002] Rolling is a commonly used method in steel production enterprises, such as hot rolling, cold rolling and other process methods. On the existing hot rolling line, the rough rolling (R1) working roll is generally equipped with a guard plate. The rough rolling working roll guard plate needs to be removed each time it goes off the line, and then it is ground on the roll grinder. After the grinding is completed, the previously removed guard plate is installed. During the disassembly and assembly of the guard plate, the existing mainstream disassembly and assembly method is to first use the overhead crane and the hoist to lift the working roll assembly to a certain height, so that it is more than 500mm away from the supporting table on the bottom surface. The worker uses a ratchet wrench to loosen the bolts that fix the guard plate. After all the bolts used to fasten the guard plate and the roll assembly are loosened, the roll assembly is lowered so that the guard plate first contacts the table for placing the guard plate, and then all the loosened bolts are removed. Then the hoist is raised to make the roll leave the guard plate, and the roll is ground on the grinder. The assembly worker checks, replaces, and adjusts the wiper on the guard plate. After the roller is ground on the grinder, the roller assembly is hoisted by an overhead crane and a hoist for installation, and the roller assembly is slowly lowered. During the lowering process, the relative position between the installation position on the roller and the guard plate needs to be adjusted. During the adjustment process, the position of the roller assembly is controlled by the overhead crane to adjust the up and down and left and right positions. The overhead crane moves a large range during the control process, and it is very difficult to align the guard plate with the installation position on the roller assembly. Therefore, a lot of time is easily wasted during the installation process, delaying the construction progress and seriously affecting the production progress.

[0024] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below, and preferred embodiments of the present invention are given. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0026] Example:

[0027] See also Figure 1-Figure 4 The present embodiment provides a support frame for disassembling and assembling a roller guard plate, comprising a base plate 1 and two support plates 2, wherein the two support plates 2 are arranged on the base plate 1 at intervals, each support plate 2 is provided with a clearance groove 21, and the top of the support plate 2 has two abutting shoulders 22, which are respectively located on both sides of the clearance groove 21.

[0028] Specifically, the positions of the two support plates 2 correspond to the supporting positions on the roll assembly 6 , and the roll assembly 6 and the guard plate 5 are supported by the two abutting shoulders 22 on the support plates 2 .

[0029] It is understandable that when the roll needs to be repaired, the guard plate 5 on the roll needs to be removed. In the process of disassembling and assembling the guard plate 5, the roll assembly 6 and the guard plate 5 are first hoisted to the roll guard plate disassembly support frame by the overhead crane and the hoisting device, and the roll assembly 6 and the guard plate 5 are supported by the abutting shoulder 22 on the support plate 2. The worker uses a wrench to remove the bolts used to fix the guard plate 5 and the roll assembly 6. At this time, the guard plate 5 is removed and supported on the support plate 2, and the roll assembly 6 is moved away for maintenance. After the roll assembly 6 is repaired, it is hoisted to the roll guard plate 5 disassembly frame, and then the guard plate 5 is fixed to the roll assembly 6 by bolts for assembly and fixation. The position of the guard plate 5 does not change during the installation and disassembly process. Therefore, the guard plate 5 can be quickly aligned with the installation position on the roll assembly 6 when disassembling and installing the guard plate 5, which reduces the operation difficulty, saves the operation and installation time, and improves the economic efficiency. Secondly, there is no need to suspend the roll and the guard plate 5 in mid-air for construction, which reduces the risk of the guard plate 5 or the roll assembly 6 falling from the hanger and injuring people.

[0030] Furthermore, it also includes a cushioning assembly 3, which is detachably connected to the top of the abutting shoulder 22, and the cushioning assembly 3 is arranged one-to-one with the abutting shoulder 22. It should be noted that, in the case where the supporting positions of the roll assembly 6 and the guard plate 5 are not in the same plane, it is necessary to use the cushioning assembly 3 to support the guard plate 5 or the roll assembly 6. In this embodiment, the guard plate 5 is supported as an example, the roll assembly 6 is supported by the abutting shoulder 22, and the guard plate 5 is supported by the cushioning assembly 3, so that the position of the guard plate 5 and the installation position on the roll are located in the same horizontal plane, so as to facilitate the removal of the guard plate 5 from the roll assembly 6 or the installation of the guard plate 5 on the roll assembly 6.

[0031] Furthermore, the cushioning assembly 3 includes a cushion block 31, which is cushioned on the upper part of the abutting shoulder 22. The cushion block 31 supports the guard plate 5 to facilitate the disassembly and assembly of the guard plate 5. It should be noted that the cushion block 31 is directly placed on the upper part of the abutting shoulder 22, and can be directly placed on the bottom plate 1 when not in use. It can be taken at any time when in use, and does not need to be fixed with fasteners. It is convenient to take and disassemble, and the cushion block 31 is a square block, which is easy to produce and manufacture, which is conducive to reducing the cost investment of the equipment.

[0032] Preferably, a positioning groove 311 is provided at the bottom of the cushion block 31, and the positioning groove 311 is provided in the middle of the cushion block 31, and the width of the positioning groove 311 is slightly wider than the thickness of the support plate 2, and the cushion block 31 straddles the upper part of the abutting shoulder 22 through the positioning groove 311. The cushion block 31 is installed on the upper part of the abutting shoulder 22 in a straddling manner, and the cushion block 31 is restricted from moving in the thickness direction of the support plate 2, so as to prevent the cushion block 31 from moving and falling during the process of supporting the guard plate 5.

[0033] Furthermore, the pad holding assembly 3 also includes a pad 32, which is arranged in the positioning groove 311 so that the pad 32 is padded between the pad block 31 and the abutting shoulder 22. The pad 32 is provided to increase the pad holding height of the pad block 31, so that the installation positions of the guard plate 5 and the roller assembly 6 are on the same horizontal plane, so as to facilitate the disassembly and assembly of the guard plate 5.

[0034] Preferably, the thickness of the pad 32 is set between 0.5 mm and 20 mm. The support height of the guard plate 5 can be adjusted by using pads 32 of different thicknesses to be arranged between the pad block 31 and the abutting shoulder 22 .

[0035] Further, the pad 32 includes a sub-pad 321, and the sub-pad 321 is composed of at least one of a 0.5 mm thick pad, a 1 mm thick pad, a 2 mm thick pad, and a 5 mm thick pad. It can be understood that the pad 32 is composed of sub-pads 321 of different thicknesses, so as to adjust the thickness of the pad 32. It should be noted that the pad 32 can be composed of a certain sub-pad 321, or a plurality of different sub-pads 321, or a plurality of the same sub-pads 321, and can be combined and matched according to actual needs.

[0036] Furthermore, the clearance groove 21 is a circular arc groove that is concave downward. It can be understood that grooving the support plate 2 will reduce the rigidity of the support plate 2, but if the support plate 2 is not grooved, the roller will be directly supported on the support plate 2, causing damage to the surface of the roller. By setting the clearance groove 21 as a circular arc groove close to the roller, the rigidity of the support plate 2 can be reduced to a minimum. It should be noted that the arc of the circular arc groove should be slightly larger than the roller so that a gap is maintained between the side wall of the circular arc groove and the roller to prevent the roller from contacting the side wall of the circular arc groove.

[0037] Furthermore, reinforcing ribs 4 are provided between the support plate 2 and the bottom plate 1. A plurality of reinforcing ribs 4 are provided, and reinforcing ribs 4 are arranged on both sides of each support plate 2. The reinforcing ribs 4 are used to strengthen the support and improve the rigidity of the support plate 2 to prevent the support plate 2 from being deformed too much during the support process and failing to achieve a good support effect. The support plate 2 is arranged along the length direction of the bottom plate 1. It should be noted that the reinforcing ribs 4 on the side of the support plate 2 close to the roller assembly 6 are shorter to leave enough space for the guard plate 5 and the roller assembly 6, and the reinforcing ribs 4 on the side away from the roller assembly 6 are longer to enhance the rigidity of the bottom plate 1.

[0038] The working principle of the technical solution of this embodiment is: when the roll needs to be repaired, the roll assembly 6 and the guard plate 5 are hoisted to the roll guard plate disassembly support frame by the overhead crane and the hoisting device, the roll assembly 6 is supported by the abutting shoulder 22 on the support plate 2, and the guard plate 5 is supported by the pad holding assembly 3. When the height of the pad 31 in the pad holding assembly 3 is not enough to support the guard plate 5, a pad 321 is placed between the pad 31 and the abutting shoulder 22 until the pad 31 can just support the guard plate 5. The worker removes the bolts used to fix the guard plate 5 and the roll assembly 6, and hoists the roll assembly 6 away for maintenance. At this time, the guard plate 5 is supported on the pad 31 and the position does not change. When the roller assembly 6 is repaired, it is hoisted onto the roller guard plate disassembly support frame so that the roller assembly 6 is supported on the abutment shoulder 22 on the support plate 2. At this time, the installation position on the guard plate 5 and the roller assembly 6 is located in the same horizontal plane, and the workers can directly install bolts to fix it.

[0039] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
