Description

Technical Field

[0001] This utility model relates to the field of rolling mill stand disassembly technology, specifically an auxiliary tooling for facilitating the disassembly of a 1000 rolling mill stand. Background Technology

[0002] The rolling mill archway is a core load-bearing component of the rolling mill. It is typically a large cast steel structure, weighing tens to hundreds of tons, with a complex structure. The dismantling process requires precise control to avoid deformation or damage, thus necessitating the use of various auxiliary tools. Specialized lifting lugs or balance beams are designed according to the archway's structure to ensure a stable center of gravity during hoisting, preventing tilting or uneven stress. These, combined with large-tonnage hooks, provide the primary lifting power for detaching the archway as a whole from the rolling mill base or frame.

[0003] In existing technologies, such as the anti-tipping device for a rolling mill stand disclosed in CN221435524U, a support plate and support legs are included. The support plate is provided with clamping device fixing holes and pad fixing holes. The clamping device fixing holes are located between adjacent pad fixing holes. The number of equal-height pads matches the number of pad fixing holes. Each equal-height pad includes a pad and a pin. The pin passes through the pad fixing hole. The clamping plate of the clamping mechanism is provided with a sliding groove. A double-ended screw passes between the sliding groove and the clamping device fixing hole. The long axes of the clamping device fixing hole, the pad fixing hole, and the sliding groove are parallel to each other. By adjusting the positions of the equal-height pads, clamps, and double-ended screws, it is suitable for the vertical placement of various specifications of rolling mill stands. It facilitates the disassembly of the rolling mill stand for maintenance work by maintenance personnel, reducing the labor intensity and skill requirements of maintenance personnel. This anti-tipping device for the rolling mill stand ensures that the rolling mill stand will not tip over due to external forces.

[0004] The existing tooling can be used to vertically place various sizes of rolling mill stands by adjusting the positions of the equal height blocks, clamps, and double-ended screws. However, since the 1000 rolling mill stand itself is quite tall, personnel need to stand on scaffolding when dismantling it. When two people stand on scaffolding at the same time to carry out dismantling operations, the space is relatively small, which poses a significant safety hazard. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Given that the existing technology has the problem that, due to the height of the 1000 rolling mill archway itself, personnel need to stand on scaffolding during dismantling, and the space is relatively small when two people are standing on the scaffolding at the same time to carry out dismantling operations, which poses a significant safety hazard.

[0007] To solve the above problems, this utility model provides the following technical solution:

[0008] An auxiliary tooling for easy disassembly of a 1000 rolling mill stand includes a tooling base, column supports, a limiting plate, and a moving trolley. Two column supports are welded and fixed to the upper surface of the tooling base. The limiting plate is fixed to the side wall of the column supports. Two moving trolleys are mounted on top of the tooling base. The tooling also includes:

[0009] A dual-axis motor and a fixing block are provided. The dual-axis motor is located on the inner wall of the tooling base, and the fixing block is located on one side of the mobile trolley.

[0010] As a further improvement of this utility model: both power output shafts of the dual-axis motor are fixed with transmission rods, and the ends of the transmission rods are fixed with active helical teeth.

[0011] As a further embodiment of this utility model: the side wall of the active helical tooth is engaged with a driven helical tooth, and a threaded tube is fixed on the upper surface of the driven helical tooth.

[0012] As a further embodiment of this utility model: the internal thread of the threaded tube is connected to a screw, and an adjusting plate is welded and fixed to the upper surface of the screw.

[0013] As a further improvement of this utility model: the lower end of the adjustment plate is fixed with two guide rods, and the lower ends of the two guide rods are telescopically connected to a limiting tube fixed on the tooling base.

[0014] As a further embodiment of this utility model: the fixing block includes a movable rod, which is telescopically connected inside the fixing block. A fixing ring is fixed to the lower end of the movable rod, and a compression spring abuts against the lower surface of the fixing ring.

[0015] As a further improvement of this utility model: the lower surface of the movable rod is inserted into a limiting hole opened on the tooling base, and two sets of guide rails are fixed on the upper surface of the tooling base.

[0016] As a further improvement of this utility model: the upper ends of the two sets of guide rails are slidably connected to guide shafts, and both ends of the guide shafts are fitted with fixed bearings. The outer surface of the fixed bearings is fixed with mounting plates that are welded to the moving trolley.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model involves placing the archway on the platform, adjusting the concentricity using a pressing device, placing a jack on one side of the support, and using the jack to push out the bearing seat to complete the bearing seat disassembly. The dual-shaft motor drives the transmission rod to rotate, synchronously driving the two active helical teeth to rotate, causing the active helical teeth to mesh with the driven helical teeth to rotate, thereby driving the threaded tube to rotate. With the cooperation of the guide rod and the limiting tube, the rotation of the threaded tube can drive the threaded screw to move vertically, thereby driving the adjusting plate to move vertically and adjusting the height of the misaligned roller.

[0019] 2. When the movable rod is manually pulled, the retaining ring compresses the compression spring. At this time, the bottom of the movable rod separates from the limiting hole, thereby releasing the fixation of the moving trolley. After the horizontal position of the moving trolley is adjusted, the movable rod is released again. During the extension and reset process of the compression spring, the movable rod is pushed into the limiting hole, thereby limiting the movement of the moving trolley and effectively reducing the possibility of accidental movement of the moving trolley.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0029] Please see Figures 1-5 This embodiment provides an auxiliary tooling for easy disassembly of a 1000 rolling mill stand, including a tooling base 1, column supports 2, a limiting plate 3, and a moving trolley 4. Both column supports 2 are welded and fixed to the upper surface of the tooling base 1, the limiting plate 3 is fixed to the side wall of the column supports 2, and the two moving trolleys 4 are installed above the tooling base 1.

[0030] The auxiliary tooling for facilitating the disassembly of the 1000 rolling mill stand also includes a dual-axis motor 5 and a fixing block 6. The dual-axis motor 5 is located on the inner wall of the tooling base 1, and the fixing block 6 is located on one side of the moving trolley 4.

[0031] Specifically, both power output shafts of the dual-axis motor 5 are fixed with transmission rods 51, and the end of the transmission rods 51 is fixed with a driving helical gear 52. The side wall of the driving helical gear 52 is engaged with a driven helical gear 53, and the upper surface of the driven helical gear 53 is fixed with a threaded tube 54.

[0032] Furthermore, the dual-axis motor 5 can drive the transmission rod 51 to rotate, which in turn synchronously drives the two active helical teeth 52 to rotate, causing the active helical teeth 52 to mesh with the driven helical teeth 53 to rotate, thereby driving the threaded tube 54 to rotate.

[0033] Specifically, the threaded tube 54 has a screw 55 connected to its internal thread. An adjusting plate 56 is welded and fixed to the upper surface of the screw 55. Two guide rods 57 are fixed to the lower end of the adjusting plate 56. The lower ends of the two guide rods 57 are telescopically connected to a limiting tube 58 fixed to the tooling base 1.

[0034] Furthermore, with the cooperation of the guide rod 57 and the limiting tube 58, the rotation of the threaded tube 54 can drive the threaded screw 55 to move vertically, which in turn drives the adjusting plate 56 to move vertically, thus enabling the adjustment of the height of the misaligned roller.

[0035] In use, the tooling base 1 is placed in a suitable position. The upright support 2 facilitates the placement of the left and right misaligned rollers of the archway tie rod. The limiting plate 3 can limit the misaligned rollers. The moving trolley 4 facilitates the placement of the upper and lower bearing seats of the archway. By placing the archway on this platform, the concentricity is adjusted using the pressing device. The jack is placed on one side of the support, and the bearing seat is pushed out using the jack to complete the disassembly of the bearing seat. The dual-shaft motor 5 can drive the transmission rod 51 to rotate, which in turn drives the two active helical teeth 52 to rotate synchronously. The active helical teeth 52 mesh with the driven helical teeth 53 to rotate, which in turn drives the threaded tube 54 to rotate. With the cooperation of the guide rod 57 and the limiting tube 58, the rotation of the threaded tube 54 can drive the threaded screw 55 to move vertically, which in turn drives the adjusting plate 56 to move vertically. This allows the height of the misaligned rollers to be adjusted, making it convenient for workers to use.

[0036] In summary, when using this auxiliary tooling that facilitates the disassembly of the 1000 mill stand, the stand is placed on the platform, the concentricity is adjusted using the pressing device, the jack is placed on one side of the support, and the bearing seat is pushed out using the jack to complete the disassembly of the bearing seat. The dual-shaft motor 5 drives the transmission rod 51 to rotate, which synchronously drives the two active helical teeth 52 to rotate, so that the active helical teeth 52 mesh with the driven helical teeth 53 to rotate, thereby driving the threaded tube 54 to rotate. With the cooperation of the guide rod 57 and the limit tube 58, the rotation of the threaded tube 54 can drive the threaded screw 55 to move vertically, thereby driving the adjusting plate 56 to move vertically and adjust the height of the misaligned roll.

[0037] The fixed block 6 includes a movable rod 61, which is telescopically connected inside the fixed block 6. A fixing ring 62 is fixed to the lower end of the movable rod 61, and a compression spring 63 abuts against the lower surface of the fixing ring 62.

[0038] Furthermore, when the movable rod 61 is manually pulled, the retaining ring 62 will compress the compression spring 63. At this time, the bottom of the movable rod 61 will separate from the limiting hole 64, thereby releasing the fixation of the moving trolley 4.

[0039] Specifically, the lower surface of the movable rod 61 is inserted into the limiting hole 64 opened on the tooling base 1, and two sets of guide rails 65 are fixed on the upper surface of the tooling base 1.

[0040] Furthermore, the guide shaft 66 at the bottom of the moving trolley 4 is connected to the guide rail 65 provided on the tooling base 1.

[0041] Specifically, the upper ends of the two sets of guide rails 65 are slidably connected to guide shafts 66, and both ends of the guide shafts 66 are fitted with fixed bearings 67. The outer surface of the fixed bearings 67 is fixed with mounting plates 68 that are welded to the moving trolley 4.

[0042] Furthermore, during the process of the compression spring 63 extending and resetting, it will push the movable rod 61 into the limiting hole 64, thereby limiting the movement of the trolley 4 and effectively reducing the possibility of the trolley 4 moving unexpectedly.

[0043] In use, the guide shaft 66 at the bottom of the moving trolley 4 is connected to the guide rail 65 on the tooling base 1. With the cooperation of the fixed bearing 67 and the mounting plate 68, the moving trolley 4 can be moved easily. When the movable rod 61 is manually pulled through the fixed block 6 on the moving trolley 4, the fixed ring 62 will compress the compression spring 63. At this time, the bottom of the movable rod 61 will separate from the limiting hole 64, thereby releasing the fixation of the moving trolley 4. After the horizontal position of the moving trolley 4 is adjusted, the movable rod 61 is released. During the extension and reset process of the compression spring 63, the movable rod 61 will be pushed into the limiting hole 64, thereby limiting the movement of the moving trolley 4 and effectively reducing the possibility of accidental movement of the moving trolley 4.

[0044] In summary, when using this auxiliary tooling for disassembling the 1000 mill stand, the stand is placed on the platform, and the concentricity is adjusted using the pressing device. A jack is placed on one side of the support, and the bearing seat is pushed out using the jack, thus completing the bearing seat disassembly. The dual-shaft motor 5 drives the transmission rod 51 to rotate, synchronously driving the two active helical gears 52 to rotate. This causes the active helical gears 52 to mesh with the driven helical gears 53, which in turn drives the threaded tube 54 to rotate. With the cooperation of the guide rod 57 and the limiting tube 58, the rotation of the threaded tube 54 drives the threaded screw 55 to move vertically. The movement of the movable rod 61 causes the adjusting plate 56 to move vertically, adjusting the height of the roller. When the movable rod 61 is manually pulled, the fixing ring 62 compresses the pressure spring 63. At this time, the bottom of the movable rod 61 separates from the limiting hole 64, thereby releasing the fixation of the moving trolley 4. After the horizontal position of the moving trolley 4 is adjusted, the movable rod 61 is released. During the extension and reset process of the pressure spring 63, the movable rod 61 is pushed into the limiting hole 64, thereby limiting the movement of the moving trolley 4 and effectively reducing the possibility of accidental movement of the moving trolley 4.
