Description

Technical Field

[0001] This utility model relates to the technical field of maintenance platforms, and in particular to a centering uncoiler maintenance platform based on a positioning reference. Background Technology

[0002] In the field of coil processing in the metallurgical industry, especially in cold rolling and pickling production lines, the uncoiler is a crucial piece of equipment for continuously feeding metal strip into downstream processing units, and its importance is self-evident. Regular maintenance and overhaul of the uncoiler are essential for ensuring production efficiency and product quality. Traditional uncoiler maintenance typically relies on manual disassembly of components (such as roller boxes), using basic tools and temporary support structures. In recent years, uncoiler technology has made significant progress in automation, precision, and production efficiency; however, the development of maintenance support equipment has lagged behind. Existing maintenance platforms (if any) are usually static structures or temporary ladders, scaffolding, etc., placed around the uncoiler by manual positioning. These platforms are designed to provide maintenance personnel with access to critical components, but their design and function are not fully adapted to the specific needs of modern high-speed, high-precision uncoiler systems. The lack of dedicated maintenance platforms tailored to the structure and operating characteristics of uncoilers leads to persistent inefficiencies and safety hazards during maintenance, failing to meet the urgent needs of modern industrial production for efficient and safe maintenance.

[0003] Due to the lack of a dedicated adjustable maintenance platform, maintenance personnel usually rely on ladders or high-altitude work surfaces. These facilities are inherently unstable and difficult to align precisely with the uncoiler's rolls. This alignment deviation complicates the disassembly and replacement of the roll boxes, prolongs downtime, and reduces production efficiency. Utility Model Content

[0021] Please refer to Figure 1As shown, a centering uncoiler maintenance platform based on a positioning reference includes a welding platform 11, a moving platform 12, and a support leg module. Two moving platforms 12 are slidably arranged at both ends of the welding platform 11. A base 13 is provided at the lower end of the welding platform 11. The base 13 has a cylindrical structure, and the support leg module is provided below the base (13).

[0022] It should be noted that the two mobile platforms 12 are slidably configured at both ends of the welding platform 11 to achieve a telescopic function. They slide on the slide rails 14 on both sides of the welding platform 11 via rollers 15 and are equipped with locking mechanisms, allowing them to be fixed after being extended to a suitable position. When extended, they increase the standing area for easy maintenance operations; when retracted, they reduce the overall volume for easy installation and storage. The lower end of the welding platform 11 is provided with a cylindrical base 13. The inner diameter of the base 13 is adapted to the outer diameter of the uncoiler's reel, and the inner diameter is 40-50mm larger than the outer diameter of the reel to ensure smooth operation. The set is fitted and maintains the fit accuracy. The cylindrical structure achieves coaxial alignment with the uncoiler shaft through the up and down adjustment function of the steel coil saddle of the feeding trolley, and provides radial support by utilizing the tension of the opening of the coil. The base (13) is provided with a support leg module, which includes four support legs. The bottom of each support leg adopts a combination structure of channel steel 26 of model 10 and bolts. The groove of channel steel 26 matches the width of the uncoiler track to ensure a stable engagement. The height of the support leg can be adjusted by bolts. The adjustment range is 50-150mm to adapt to different maintenance needs, thereby ensuring the stability and safety of the platform.

[0023] A slide rail 14 is provided above the welding platform 11. The slide rail 14 has a groove along its length. The moving platform 12 is slidably connected to the groove via rollers 15.

[0024] It should be noted that the rollers 15 are fitted into the slide groove to ensure the stability and smoothness of the mobile platform 12 during sliding. At the same time, the mobile platform 12 is equipped with a locking mechanism, which can be fixed after sliding to the desired position to ensure the safety of maintenance personnel when standing. The design of the slide rail 14 and the slide groove allows the mobile platform 12 to flexibly extend and retract at both ends of the welding platform 11. When extended, it increases the standing area for maintenance operations, and when retracted, it reduces the overall volume for installation and storage, thereby improving the operational convenience and spatial adaptability of the maintenance platform.

[0025] A limiting plate 16 is fixed on the mobile platform 12. The limiting plate 16 has a positioning hole 17. Several positioning tubes 18 are provided on the side of the slide rail 14 away from the slide groove. The limiting plate 16 is locked to the positioning tubes 18 by a safety pin 19.

[0026] It should be noted that the limiting plate 16 is fixed to the moving platform 12 by welding or bolts. The diameter of the positioning hole 17 is matched with the diameter of the safety pin 19 to ensure that the safety pin 19 can be smoothly inserted and securely connected. The positioning tubes 18 on the slide rail 14 are spaced apart along the length direction. The position of each positioning tube 18 corresponds to the different position requirements of the moving platform 12 during extension and retraction. The inner diameter of the positioning tube 18 matches the outer diameter of the safety pin 19 to ensure stability during locking. When the moving platform 12 slides to the required position, the maintenance personnel can insert the safety pin 19 into the positioning hole 17 of the limiting plate 16 and the corresponding positioning tube 18 to lock the moving platform 12 on the slide rail 14, preventing sliding or shaking and ensuring the safety and stability of the maintenance operation. This design, through the cooperation of the limiting plate 16, positioning hole 17, positioning tube 18 and safety pin 19, achieves precise positioning and reliable fixation of the moving platform 12 during extension and retraction, further improving the operational flexibility and safety of the maintenance platform.

[0027] The slide 14 is provided with two pairs of limiting steps 20.

[0028] It should be noted that each pair of limiting steps 20 has a raised structure, is symmetrically distributed along the length of the slide rail 14, and is set parallel to the slide groove. The height and width of the limiting steps 20 are designed to fit the bottom structure of the mobile platform 12. When the mobile platform 12 slides to the extreme positions at both ends of the slide rail 14, it abuts against the limiting steps 20 through the limiting plate 16, thereby preventing the mobile platform 12 from overextending or retracting and detaching from the slide groove. The design of the limiting steps 20 not only provides a clear physical boundary for the sliding of the mobile platform 12, but also enhances the stability of the mobile platform 12 at the extreme positions by increasing the contact area, reducing the risk of sliding detachment caused by misoperation or external force, thereby further ensuring the safety and reliability of the maintenance platform during use.

[0029] The mobile platform 12 is equipped with a first fence 21 and a second fence 22, and the welding platform 11 is equipped with a third fence 23.

[0030] It should be noted that guardrail 1 (21) and guardrail 2 (22) are fixed to the edges of the two mobile platforms 12 respectively, and are connected by welding or bolts to ensure stability. The height and structural design of guardrail 1 (21) and guardrail 2 (22) meet safety standards and can effectively prevent maintenance personnel from falling when the mobile platform 12 is extended or retracted. Guardrail 3 (23) is set on the top perimeter of the welding platform 11, made of high-strength material, and is fixed to the welding platform 11 by welding or detachable connection. Its height is consistent with that of guardrail 1 (21) and guardrail 2 (22), forming a continuous protective barrier. Guardrail 1 (21), guardrail 2 (22), and guardrail 3 (23) together constitute the overall safety protection system of the maintenance platform. Especially when the mobile platform 12 is extended to increase the standing area, the three work together to ensure the all-round safety of maintenance personnel when working at height. In addition, the design of the guardrail takes into account the ease of operation, with a smooth surface and no sharp edges and corners to reduce the risk of accidental collision or scratches, thereby significantly improving the safety and comfort of the maintenance platform.

[0031] The outrigger module includes a square tube 24 and a square tube 25, with the square tube 24 connected to the square tube 25 by a bolt.

[0032] It should be noted that square tube 24 and square tube 25 are made of high-strength steel. Square tube 24 is the inner sleeve, and square tube 25 is the outer sleeve. Multiple height adjustment holes are opened on the side walls of square tube 24 and square tube 25, and the holes are arranged at intervals along the vertical direction. By passing a bolt through the corresponding hole of square tube 24 and square tube 25 and locking it with a nut, the height of the outrigger can be precisely adjusted. The adjustment range is 50-150mm to meet the needs of different maintenance scenarios. A channel steel 26 of model 10 is fixed at the bottom of square tube 24. The groove of the channel steel 26 is adapted to the width of the uncoiling machine track to ensure a stable engagement and prevent shaking. This design, through the sliding fit of square tube 24 and square tube 25 and the locking mechanism of bolt 1, not only provides flexible height adjustment function, but also ensures the structural rigidity and stability of the outrigger module under load and lateral force resistance, thereby providing reliable support for the maintenance platform and enhancing the overall safety and applicability.

[0033] The operating steps of the centering uncoiler maintenance platform based on the positioning reference are as follows: First, place the cylindrical base 13 of the maintenance platform on the steel coil saddle of the loading trolley, ensuring that the base 13 is firmly in contact with the saddle to prevent displacement during installation. Next, operate the up-and-down adjustment function of the steel coil saddle of the loading trolley to adjust the axis of the cylindrical base 13 of the maintenance platform, keeping it on the same horizontal line as the axis of the uncoiler shaft, ensuring that the coaxiality of the two meets the design requirements. Then, control the axial movement of the steel coil saddle of the loading trolley to slowly push the maintenance platform into the uncoiler shaft until the platform reaches the predetermined maintenance position. Start the uncoiler to open the shaft, using the tension of the opening to generate radial support force on the cylindrical base 13, ensuring the stability of the platform in the radial direction.

[0034] According to maintenance needs, operators can extend the movable platforms 12 on both sides of the welding platform 11 to a suitable length by sliding them through the rollers 15 in the slide grooves of the slide rail 14. They can then lock them by inserting safety pins 19 into the positioning holes 17 of the limit plate 16 and the positioning tubes 18 on the slide rail 14, increasing the standing area for easier maintenance. If a reduction in size is required, the locking mechanism can be released to retract the movable platform 12. Next, four support leg modules are installed. By adjusting the bolts between square tube 1 24 and square tube 2 25, the height of the support legs (range 50-150mm) is adjusted so that the grooves of the channel steel 26 at the bottom of the support legs accurately engage with the two rails of the uncoiler. The bolts are then tightened to ensure stable support of the support legs for the platform. At this point, maintenance personnel can stand on the platform equipped with guardrails 1 21, 22, and 3 23 to safely disassemble the uncoiler roll box. After the work is completed, follow the reverse steps of installation: unlock, retract the mobile platform 12, remove the outriggers, release the tension of the reel, and then use the loading trolley to move the maintenance platform off the reel, completing the dismantling process. This process, through precise alignment, stable support, and flexible telescopic design, significantly improves maintenance efficiency and safety.
