Description

Technical Field

[0001] This utility model relates to the field of wind turbine tower technology, specifically a wind turbine tower support frame. Background Technology

[0002] With the rapid development of the wind power industry, the demand for wind turbine towers is constantly increasing, and the production volume of wind turbine towers has also increased significantly. In the production process of wind turbine towers, in order to extend the overall length of the wind turbine tower, the ends of two sets of wind turbine towers need to be connected. During this process, support frames are used to provide stable support for the wind turbine towers to ensure the connection accuracy.

[0003] Existing wind turbine tower support frames have significant drawbacks: First, the support points are fixed and cannot be flexibly adjusted according to the actual position of the wind turbine tower ends. This results in uneven support forces at the ends when two wind turbine towers are placed on the support frame, easily causing end position shifts and ultimately leading to misalignment. Second, wind turbine towers are heavy and have an arc-shaped outer structure, making it difficult for traditional support frames to adjust their position during the support process. Manual assistance with cranes is required to repeatedly move the wind turbine towers to correct their position, which is not only time-consuming and labor-intensive but also seriously affects the docking efficiency. Third, traditional support frames only contact the wind turbine towers through a single support structure, resulting in insufficient support stability. The wind turbine towers are prone to tilting during docking, posing a safety hazard.

[0004] There is currently no effective solution to the above problems in the existing technology. Therefore, there is an urgent need for a wind turbine tower support frame that can flexibly adjust the support position, has strong support stability, and can improve docking efficiency. Utility Model Content

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a wind turbine tower support frame that solves the problems of existing wind turbine tower support frames being unable to flexibly adjust the support points according to the end position of the wind turbine tower, having poor support stability, and having low docking efficiency.

[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a wind turbine tower support frame, including a fixed support frame, with a wind turbine tower placed on the top of the fixed support frame, and an adjustment mechanism on the side of the fixed support frame for adapting to the support position at the end of the wind turbine tower.

[0007] The adjustment mechanism includes a movable support frame, a hydraulic drive assembly, a support roller, and a stabilizing roller. The specific structure and function of each component are as follows: Mobile support frame: It is movably set on the side of the fixed support frame. Its core function is to provide adjustable support for the ends of the wind turbine towers. By adjusting its position, it ensures that the support points at the ends are consistent when the two sets of wind turbine towers are connected, thus fundamentally avoiding the problem of misalignment caused by the offset of the support points.

[0008] Hydraulic drive assembly: Serving as the power source for the mobile support frame, it includes a mounting box, a hydraulic telescopic rod, and a moving block. The mounting box is located inside the base of the fixed support frame and is embedded within the fixed support frame, ensuring a secure installation and preventing damage to internal components from external dust and impurities. The hydraulic telescopic rod is installed inside the mounting box, with its end fixedly connected to the moving block. The moving block is fixed to both sides of the mobile support frame and slides within the mounting box. When the hydraulic telescopic rod is activated, its extension and retraction pushes the moving block along the inside of the mounting box, thereby causing the mobile support frame to move smoothly along the side of the fixed support frame. This achieves precise adjustment of the support position without manual intervention, significantly improving adjustment efficiency.

[0009] Support roller: Rotated and mounted above the mobile support frame via a support component, the support roller's exterior is designed with an arc shape that perfectly matches the outer curved surface of the wind turbine tower. This design ensures a tight fit between the support roller and the wind turbine tower, guaranteeing support stability. Furthermore, as the mobile support frame moves, the support roller's rolling motion reduces friction with the wind turbine tower, preventing wear on the tower's outer surface during movement and enhancing the mobile support frame's mobility.

[0010] Stabilizing rollers: These are rotatably mounted above the movable support frame via stabilizing components and symmetrically distributed on both sides of the supporting rollers. The stabilizing rollers and supporting rollers form a "three-point" collaborative support structure, providing support from the bottom and sides of the wind turbine tower simultaneously. This effectively enhances the stability of the wind turbine tower, prevents it from tilting due to a shift in the center of gravity during docking, and improves operational safety.

[0011] To further improve the overall performance of the support frame, the following optimizations have been made to this invention: The mobile support frame is movably mounted above the base, which is made of high-strength steel, providing a stable installation foundation for both the fixed and mobile support frames, ensuring that the entire support frame does not deform when bearing the weight of the wind turbine tower.

[0012] The base has a limiting groove extending along the moving direction of the movable support frame. A round rod is fixedly connected inside the movable support frame, and a roller is movably sleeved on the outside of the round rod, rolling within the limiting groove. This structure reduces friction between the movable support frame and the base, making movement smoother. Furthermore, the limiting groove restricts the rolling trajectory of the roller, thus limiting the moving direction of the movable support frame, preventing deviation during movement, and ensuring the accuracy of the support position adjustment.

[0013] The fixed support frame is externally fixedly connected to a support plate, and the movable support frame is movably sleeved on the outside of the support plate. The support plate adopts a rectangular steel plate structure, and its length is adapted to the maximum moving distance of the movable support frame. It can not only provide auxiliary support to the bottom of the movable support frame to prevent the movable support frame from tilting due to unilateral force, but also further limit the moving trajectory of the movable support frame and improve the stability of movement.

[0014] This utility model discloses a wind turbine tower support frame, which has the following beneficial effects: This wind turbine tower support frame uses a hydraulic drive assembly to move the mobile support frame. The support points can be flexibly adjusted according to the actual position of the wind turbine tower ends, ensuring that the end support points are consistent when two sets of wind turbine towers are docked. This completely solves the problem of misalignment caused by fixed support points in traditional support frames, eliminating the need for manual adjustments of the wind turbine tower position using a crane, thus improving docking efficiency. The support rollers adopt a structure adapted to the curved surface of the wind turbine tower, ensuring a close fit. Simultaneously, symmetrically distributed stabilizing rollers and the support rollers form a "three-point" collaborative support, significantly enhancing support stability and effectively preventing the wind turbine tower from tilting during docking, improving operational safety. When the mobile support frame moves, the rollers roll within the limiting grooves, and the support plate provides limiting support for the mobile support frame; this double limiting structure ensures smooth movement. The rolling design of the support rollers reduces friction with the wind turbine tower, preventing wear on the outer surface of the wind turbine tower and protecting its appearance and structural integrity.

[0019] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0020] Please see Figures 1-4 This utility model provides a technical solution: a wind turbine tower support frame, including a fixed support frame 1, with a base 101 fixedly connected to the bottom end of the fixed support frame 1. The base 101 is made of Q345 steel and has a thickness of 20mm to ensure load-bearing capacity. The top of the fixed support frame 1 is used to place the wind turbine tower 102, and the side of the fixed support frame 1 is provided with an adjustment mechanism.

[0021] The specific assembly relationships of the adjustment mechanism are as follows: Assembly of the movable support frame and hydraulic drive assembly: The movable support frame 2 is movably disposed on the side of the fixed support frame 1 and located above the base 101; the base 101 has an internal mounting cavity, and the mounting box 209 is embedded and fixed in the mounting cavity and located inside the fixed support frame 1; a hydraulic telescopic rod 210 (model: HOB63×1000) is fixedly installed inside the mounting box 209 by bolts, and the end of the hydraulic telescopic rod 210 is fixedly connected to the movable block 206 by a flange; the movable block 206 has a rectangular cross section, which is adapted to the internal sliding cavity of the mounting box 209, and the end of the movable block 206 away from the hydraulic telescopic rod 210 is fixed to both sides of the movable support frame 2 by welding.

[0022] Assembly of limiting and auxiliary support structures: The base 101 has two parallel limiting grooves 211 on its outside, and the limiting grooves 211 have a U-shaped cross section; the movable support frame 2 has a round rod 207 (diameter 15mm) fixed inside by welding, and a roller 208 (made of polyurethane) is movably sleeved on the outside of the round rod 207. The outer diameter of the roller 208 is adapted to the width of the limiting groove 211, and the roller 208 rolls inside the limiting groove 211; the fixed support frame 1 has a support plate 201 (thickness 10mm) fixedly connected to its outside by bolts. The width of the support plate 201 is adapted to the width of the inner wall of the movable support frame 2, and the movable support frame 2 is movably sleeved on the outside of the support plate 201.

[0023] Assembly of support roller and stabilizing roller: A support member 205 (in the shape of a "U") is fixedly connected to the top of the movable support frame 2 by bolts. The support roller 202 is rotatably connected to the inside of the support member 205 by bearings. The radius of the outer arc surface of the support roller 202 is adapted to the outer radius of the wind turbine tower 102 (adaptation range: 2-4m). A stabilizing member 204 (also in the shape of a "U") is fixedly installed to the outside of the movable support frame 2 by bolts. The stabilizing members 204 are symmetrically distributed on both sides of the support member 205. The stabilizing roller 203 is rotatably connected to the inside of the stabilizing member 204 by bearings. The outer surface of the stabilizing roller 203 is also arc-shaped and fits against the outer surface of the wind turbine tower 102.

[0024] The steps for using this wind turbine tower support frame are as follows: Wind turbine tower placement: Using a crane (lifting capacity ≥ 120 tons), the two sets of wind turbine towers 102 to be connected are slowly placed above the fixed support frame 1 and the movable support frame 2 respectively, so that the ends of the two sets of wind turbine towers 102 initially contact each other. At this time, the support roller 202 and the stabilizing roller 203 are both in contact with the outer surface of the wind turbine tower 102.

[0025] Support position adjustment: Activate the control system of hydraulic telescopic rod 210. Hydraulic telescopic rod 210 extends and pushes moving block 206 to slide along the sliding cavity of mounting box 209. Moving block 206 drives moving support frame 2 to move along the side of fixed support frame 1. During the movement, moving support frame 2 slides along the outside of support plate 201, while roller 208 rolls along limit groove 211 to ensure smooth movement.

[0026] Docking preparation: Continuously adjust the position of the mobile support frame 2 by visual observation or laser positioning until the mobile support frame 2 is moved directly below the docking port of the two sets of wind turbine towers 102. At this time, the support points at the ends of the two sets of wind turbine towers 102 are completely aligned. Then close the hydraulic telescopic rod 210.

[0027] Docking operation: Start the docking equipment and weld or flange the ends of the two sets of wind turbine towers 102. During the docking process, the support roller 202 and the stabilizing roller 203 always provide stable support for the wind turbine tower 102 to prevent it from shifting or tilting.
