Abstract

This utility model relates to the field of wind turbine tower polishing technology, and discloses a polishing equipment for wind turbine tower production, including a gantry frame and a polishing mechanism. The polishing mechanism is located below the gantry frame and includes a lifting assembly and a polishing component. The lifting assembly includes a movable rod, a connecting plate, and a spring rod. The movable rod is located below the gantry frame, and a connecting plate is fixedly installed on the outer side of its lower end. A spring rod is fixedly connected below the connecting plate, and the upper part of the telescopic end of the spring rod is fixedly connected to the connecting plate. This utility model utilizes the fact that when the spring rod contacts a smaller taper area, the movable rod drives the polishing component to automatically descend. When it contacts a larger taper area, the squeezing force of the wind turbine tower on the telescopic end of the spring rod increases, pushing the spring rod to retract. This, in turn, drives the movable rod to rotate through the connecting plate, and the movable rod synchronously drives the polishing component to rise, thus solving the problem of uneven polishing caused by the gradual change in the diameter of the wind turbine tower.

Description

Technical Field

[0001] This utility model relates to the field of wind turbine tower polishing technology, and in particular to a polishing equipment for wind turbine tower production. Background Technology

[0002] Against the backdrop of a global energy structure accelerating its transition to a low-carbon model and driven by "dual-carbon" goals, wind power has become a focal point and mainstay in the energy sector due to its significant advantages such as being clean and renewable. In recent years, with the trend towards larger wind turbine units, the height of wind turbine towers has been continuously increasing, placing more stringent requirements on their design, materials, and manufacturing processes.

[0003] When polishing different conical surfaces of wind turbine towers, the diameter gradually changes from bottom to top, making it difficult for traditional polishing equipment to adaptively adjust the grinding trajectory and contact pressure. This can easily lead to problems such as under-polishing of small-diameter sections and over-polishing of large-diameter sections. Furthermore, the tilt angle of the conical surface can cause uneven force on the polishing head, resulting in inconsistent surface roughness. In addition, the transition area of ​​irregular conical surfaces requires manual fine processing, which is inefficient and has poor quality stability. Therefore, there is an urgent need to design a polishing equipment for wind turbine tower production. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing a polishing equipment for the production of wind turbine towers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A polishing device for wind turbine tower production, comprising a gantry crane, and further comprising: The polishing mechanism is located below the gantry frame and includes a lifting component and a polishing component. The lifting assembly includes a movable rod, a connecting plate, and a spring rod. The movable rod is located below the gantry frame, and a connecting plate is fixedly installed on the outer side of the lower end of the movable rod. A spring rod is fixedly connected below the connecting plate. The upper part of the telescopic end of the spring rod is fixedly connected to the connecting plate. The movable rod has two states: when the telescopic end of the spring rod contacts the outer surface of the wind turbine tower with a smaller taper, the movable rod can drive the polishing assembly to descend; when the telescopic end of the spring rod contacts the outer surface of the wind turbine tower with a larger taper, the movable rod can drive the polishing assembly to rise.

[0006] As a further technical solution of this utility model, the polishing assembly includes two hydraulic telescopic rods, which are respectively vertically fixed to the lower surface of the gantry frame. A connecting block is fixedly installed at the end of each hydraulic telescopic rod, and a rotating shaft is fixedly installed on the outside of one of the connecting blocks. The rotating shaft is rotatably connected to the movable rod.

[0007] As a further technical solution of this utility model, the polishing assembly also includes a drive shaft, which is rotatably connected between two connecting blocks, and a polishing roller is fixedly sleeved on the surface of the center of the drive shaft.

[0008] As a further technical solution of this utility model, a limit rod is fixedly installed below the gantry frame. The limit rod is L-shaped, with the vertical section of the limit rod fixedly connected to the gantry frame and the horizontal section of the limit rod fixedly connected to the fixed end of the spring rod.

[0009] As a further technical solution of this utility model, the bottom of the gantry frame is provided with a base, and a support seat is fixedly installed on the top of the base. There are two support seats, which are symmetrically distributed on the top of the base.

[0010] The beneficial effects of this utility model are as follows: 1. This utility model solves the problems of poor fit, uneven polishing, local missed polishing, or over-polishing caused by the gradual change in the diameter of the wind turbine tower in traditional polishing equipment. By setting up a movable rod, a connecting rod, and a spring rod, the movable rod automatically lowers the polishing component when it contacts a smaller taper area. When it contacts a larger taper area, the squeezing force of the wind turbine tower on the extension end of the spring rod increases, pushing the spring rod to retract. This, in turn, drives the movable rod to rotate through the connecting plate. The movable rod synchronously drives the polishing component to rise, thus solving the problems of poor fit, uneven polishing, local missed polishing, or over-polishing caused by the gradual change in the diameter of the wind turbine tower in traditional polishing equipment.

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see the appendix Figure 1 -Appendix Figure 4 A polishing device for wind turbine tower production includes a gantry frame 1 and a polishing mechanism located below the gantry frame 1. The polishing mechanism includes a lifting assembly and a polishing component. The lifting assembly includes a movable rod 10, a connecting plate 11, and a spring rod 9. The movable rod 10 is located below the gantry frame 1, and the connecting plate 11 is fixedly installed on the outer side of the lower end of the movable rod 10. The spring rod 9 is fixedly connected below the connecting plate 11. The upper part of the telescopic end of the spring rod 9 is fixedly connected to the connecting plate 11. The movable rod 10 has two states: when the telescopic end of the spring rod 9 contacts the outer surface of the wind turbine tower with a smaller taper, the movable rod 10 can drive the polishing component to descend; when the telescopic end of the spring rod 9 contacts the outer surface of the wind turbine tower with a larger taper, the movable rod 10 can drive the polishing component to rise. When the spring rod 9 contacts the smaller tapered area, the movable rod 10 drives the polishing assembly to automatically descend. When it contacts the larger tapered area, the squeezing force of the wind turbine tower on the telescopic end of the spring rod 9 increases, pushing the spring rod 9 to retract. This, in turn, drives the movable rod 10 to rotate through the connecting plate 11. The movable rod 10 synchronously drives the polishing assembly to rise, solving the problems of poor fit, uneven polishing, local missed polishing, or over-polishing caused by the gradual change in the diameter of the wind turbine tower in traditional polishing equipment.

[0016] Please see the appendix Figure 2 -Appendix Figure 4 In a preferred embodiment, the polishing assembly includes two hydraulic telescopic rods 8, which are respectively vertically fixed to the lower surface of the gantry frame 1. Each hydraulic telescopic rod 8 has a connecting block 6 fixedly installed at its end. A rotating shaft 12 is fixedly installed on the outside of one of the connecting blocks 6, and the rotating shaft 12 is rotatably connected to the movable rod 10. The hydraulic telescopic rod 8 drives the connecting block 6 fixed at the end to move vertically. The rotating shaft 12 on the outer side of one of the connecting blocks 6 forms a stable rotational engagement with the movable rod 10. This provides a flexible and stable fulcrum for the movable rod 10 to transmit the power of the spring rod 9 as the taper changes. Furthermore, the connecting block 6 converts the rotation of the movable rod 10 into the adaptive lifting action of the polishing component, so that the polishing component fits tightly against the conical surface of the wind turbine tower, effectively improving the consistency of the polishing finish.

[0017] Please see the appendix Figure 3 -Appendix Figure 4 In a preferred embodiment, the polishing assembly further includes a drive shaft 14, which is rotatably connected between two connecting blocks 6. A polishing roller 5 is fixedly sleeved on the surface of the center of the drive shaft 14. A drive motor is fixedly installed on one side of the other connecting block 6, which does not have a rotating shaft 12. The output shaft of the drive motor is installed at the corresponding end connection of the drive shaft 14. The drive motor drives the transmission shaft 14 to rotate through the output shaft, which in turn drives the polishing roller 5, which is fixedly sleeved on the transmission shaft 14, to rotate, thereby realizing the polishing operation on the outer surface of the wind turbine tower. The two connecting blocks 6 provide stable rotational support for the transmission shaft 14.

[0018] Please see the appendix Figure 2 -Appendix Figure 4 In a preferred embodiment, a limit rod 7 is fixedly installed below the gantry frame 1. The limit rod 7 is L-shaped, with the vertical section of the limit rod 7 fixedly connected to the gantry frame 1 and the horizontal section of the limit rod 7 fixedly connected to the fixed end of the spring rod 9. The L-shaped limiting rod 7 is fixed to the gantry frame 1 through its vertical section and the fixed end of the spring rod 9 is fixed through its horizontal section, thereby providing stable installation support for the spring rod 9 and limiting its positional deviation, ensuring that the spring rod 9 can sense the change in the taper of the wind turbine tower and transmit power.

[0019] Please see the appendix Figure 1 In a preferred embodiment, the gantry frame 1 is provided with a base 13 at the bottom, and a support seat 3 is fixedly installed on the base 13. There are two support seats 3, which are symmetrically distributed on the base 13. Two symmetrically distributed support seats 3 above the base 13 are used to stably support the wind turbine tower and provide a solid support foundation for the polishing mechanism to polish the outer surface of the wind turbine tower.

[0020] Please see the appendix Figure 1 In a preferred embodiment, two roller brackets 4 are fixedly installed at both ends of each support base 3, and two rollers 15 are rotatably installed between the two roller brackets 4. A drive motor is fixedly installed only on the outer side of the outer roller bracket 4 above each support base 3, and the output shaft of the drive motor is installed at the center of the side of the corresponding roller 15. The roller 15 between the two support frames 4 can support the wind turbine tower, and the roller 15 is driven to rotate only by the drive motor on the outer support frame 4. When the wind turbine tower is conical, the roller 15 above the two support seats 3 can achieve different speeds, which can stably drive the wind turbine tower to rotate, and can also match the difference in the diameter of the conical surface of the wind turbine tower to cooperate with the polishing operation.

[0021] Please see the appendix Figure 1In a preferred embodiment, electric slides 2 are fixedly installed on both sides above the base 13. The electric slides 2 are arranged horizontally between the two sides of the base 13. The bottom of the gantry frame 1 is fixedly connected to the slider of the electric slide 2. The electric slide 2 can drive the gantry frame 1 to move. The electric sliding tables 2 on both sides above the base 13 can drive the gantry 1 to move horizontally through the drive motor, so that the polishing mechanism moves with the gantry 1 to perform polishing operations on different axial positions of the wind turbine tower.

[0022] Two symmetrically distributed support seats 3 above the base 13 provide a stable foundation for the entire equipment. The rollers 15 between the roller brackets 4 at both ends above them jointly support the wind turbine tower. Only the drive motor on the outer roller bracket 4 drives the rollers 15 to rotate. When the wind turbine tower is conical, the rollers 15 above the two roller brackets 4 can rotate at different speeds. This not only stably drives the wind turbine tower to rotate, but also matches the difference in the diameter of the conical surface of the wind turbine tower to facilitate polishing operations. At the same time, the electric sliding tables 2 on both sides of the base 13 move the gantry frame 1 connected to them in the horizontal direction, so that the polishing mechanism can cover different axial positions of the wind turbine tower. During the polishing process, the two hydraulic telescopic rods 8 below the gantry frame 1 provide support for the polishing components through the connecting blocks 6 at their ends. The rotating shaft 12 on one of the connecting blocks 6 forms a rotational engagement with the movable rod 10, while the L-shaped limit rod 7 is a spring. Rod 9 provides a stable installation foundation. When the telescopic end of spring rod 9 contacts the surface of the wind turbine tower, if a small taper area is encountered, the movable rod 10 will drive the polishing component to automatically descend; if a larger taper area is encountered, the squeezing force of the wind turbine tower on spring rod 9 will increase, causing spring rod 9 to contract and drive the movable rod 10 to rotate through connecting plate 11, thereby raising the polishing component. This achieves adaptive lifting and lowering to closely fit the conical surface of the wind turbine tower. In addition, the drive motor on the other connecting block 6 without a rotating shaft 12 drives the transmission shaft 14 to rotate through the output shaft, which in turn drives the polishing roller 5 fixed on the transmission shaft 14 to rotate. Under the synergistic effect of the wind turbine tower rotation, the gantry 1 movement, and the adaptive adjustment of the polishing component, uniform polishing of the outer surface of the wind turbine tower is completed, effectively avoiding problems such as loose fit and uneven polishing caused by the gradual change in the diameter of the wind turbine tower in traditional equipment.

[0023] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
