It mainly plays a supporting role in the wind turbine generator set and absorbs the vibration of the unit. The tower has a special shape and a large volume. When the tower is transported and stored, it needs to be fixed with special loading and unloading and storage tooling.

[0003] A self-loading, unloading and reversing storage tool for an offshore wind turbine tower disclosed in Chinese patent publication number CN221915519U, the self-loading, unloading and reversing storage tool for an offshore wind turbine tower, through the cooperation of a placement plate, an arc-shaped support plate, fastening bolts, a first multi-stage hydraulic telescopic rod, a clamping plate, a button controller, a first bidirectional hydraulic telescopic rod, an arc-shaped top block, a second bidirectional hydraulic telescopic rod and an arc-shaped clamping block, plays a role in low-center-of-gravity installation and docking of the wind turbine tower.

[0004] However, compared with the prior art in the related field, the prior art has the following disadvantages:

[0005] The defect of lack of automatic centering function: In the existing technology, during the placement of wind turbine towers, workers need to use visual observation and experience to determine whether the tower is in the center position, which makes it difficult to ensure accuracy. As a result, the tower will shake and collide due to position deviation during transportation, increasing the risk of damage to the tower;

[0006] Low loading and unloading efficiency: When loading and unloading wind turbine towers with existing tooling, workers need to manually operate multiple clamping components and adjust their positions and clamping degrees one by one, which makes the loading and unloading process cumbersome and time-consuming;

[0007] Insufficient protection of the tower surface: When traditional tooling is used to clamp the wind turbine tower, it may easily scratch the tower surface due to unreasonable clamping methods, such as concentrated clamping points and uneven pressure. Utility Model Content

[0008] The purpose of the utility model is to overcome the shortcomings of the prior art, solve the problems mentioned in the background technology, and provide a self-loading, unloading, and transportation storage tool for offshore wind power towers.

[0013] Preferably, the clamping assembly includes a support arm movably connected to the interior of the installation box, and a second roller is rotatably provided at one end of the support arm away from the installation box.

[0014] Preferably, the support arm is in an arc shape, and the outer surfaces of the first roller and the second roller are both provided with a flexible layer.

[0015] Preferably, a slide groove is provided on the outer surface of one side of the fixed shaft, and a docking piece is slidably provided inside the slide groove.

The first roller 202 and the second roller 402 are provided to facilitate the control of the docking of the wind turbine tower and the equipment, and at the same time, with the flexible layer, scratches on the surface of the wind turbine tower can be avoided.

[0032] like Figures 2 to 4As shown, the transmission assembly 5 includes a fixed shaft 501 rotatably arranged inside the installation box 1, a gear 502 is fixedly arranged on the outer surface of the fixed shaft 501, and racks 503 are fixedly arranged at the positions of the movable member 201 corresponding to the two gears 502, and the gears 502 are meshed with the racks 503.

The provided bearings can reduce the friction force when the fixed shaft 501 rotates, and can also improve the stability of the fixed shaft 501 when rotating; as shown in FIG. Figure 5 and Figure 6 As shown, a slide groove 5011 is provided on the outer surface of one side of the fixed shaft 501, and a docking piece 5012 is slidably provided inside the slide groove 5011; a movable groove is provided at a position of the support arm 401 corresponding to the gear 502, a rotating hole is provided at a position of the support arm 401 corresponding to the fixed shaft 501, the docking piece 5012 is in the shape of a hexagon, a docking groove 4011 is provided at a position of the support arm 401 corresponding to the docking piece 5012, and six edges of the docking piece 5012 close to the docking groove 4011 are all formed into inclined surfaces, and the inclined surfaces are used to facilitate the insertion of the docking piece 5012 into the docking groove 4011, and the cooperation between the docking piece 5012 and the docking groove 4011 enables the fixed shaft 501 to drive the support arm 401 to swing, as shown in FIG. Figures 2 to 6 As shown, when the docking piece 5012 is separated from the docking groove 4011, the fixed shaft 501 can no longer drive the support arm 401 to swing, so that the support arm 401 can be adjusted individually, and when the movable part 201 slides downward, the cooperation between the gear 502 and the rack 503 is utilized to make the ends of the two support arms 401 gather together (the cooperation between the docking piece 5012 and the docking groove 4011 is utilized to make the fixed shaft 501 drive the support arm 401 to swing), so that the upper half area of ​​the wind turbine tower is clamped by the second roller 402 to ensure the stability of the wind turbine tower during transportation; when the wind turbine tower needs to be removed, the docking piece 5012 is controlled to separate from the docking groove 4011. When the docking piece 5012 is separated from the docking groove 4011, the fixed shaft 501 can no longer drive the support arm 401 to swing, so that the support arm 401 can be adjusted individually, and the wind turbine tower can be removed by the hoist at this time.

[0033] The working process is as follows:

[0034] S1: Figure 1 and Figure 4 As shown, when hoisting the wind turbine tower, the wind turbine tower is hoisted by using a hoist to dock with the gravity detection component 2;

[0035] S2: Figures 2 to 4 As shown, when the first roller 202 of the gravity detection assembly 2 contacts the wind turbine tower, the first roller 202 transmits pressure to the movable member 201, causing the movable member 201 to slide downward;

[0036] S3: Figure 2 , Figure 3 and Figure 7 As shown, when the movable member 201 slides downward, the movable rod 301 will shrink toward the inside of the fixed cylinder 302, so that the downward movement of the movable member 201 can be buffered through the cooperation between the hydraulic oil and the elastic member 303, thereby exerting a damping effect on the movable member 201;

[0037] S4: Figures 2 to 4 As shown, when the movable member 201 slides downward, the ends of the two arms 401 are brought together by the cooperation between the gear 502 and the rack 503 (the fixed shaft 501 can drive the arms 401 to swing by the cooperation between the docking member 5012 and the docking groove 4011), so that the upper half of the wind turbine tower is clamped by the second roller 402 to ensure the stability of the wind turbine tower during transportation;

[0038] S5: Figure 4 and Figure 5 As shown, when the wind turbine tower needs to be removed, the docking piece 5012 is controlled to separate from the docking groove 4011. After the docking piece 5012 is separated from the docking groove 4011, the fixed shaft 501 can no longer drive the support arm 401 to swing, so that the support arm 401 can be adjusted separately. At this time, the wind turbine tower can be removed by the hoist.

[0039] S6: In summary, the effects are as follows: automatic centering: through the synergistic effect of the gravity detection component 2 and the transmission component 5, when the wind turbine tower is placed on the tooling platform, the weight detection component 2 slides down due to gravity, triggering the transmission component 5 to control the two arms 401 to retract toward the center. This process realizes the automatic centering of the wind turbine tower, ensuring that the tower is in the center during transportation, avoiding shaking or collision due to position offset;

[0040] Stable clamping: The retraction action of the support arm 401 not only achieves the clamping of the wind turbine tower, but also adaptively adjusts the clamping force according to the weight. This stable clamping method effectively prevents the tower from shifting during transportation, improves the stability of transportation, and even in a bumpy transportation environment, the tower can maintain a firm clamping state, reducing the risk of damage caused by shaking or collision;

[0041] Fast loading and unloading: The automatic clamping function of the tooling makes the loading and unloading process of the wind turbine tower faster and more convenient. There is no need to manually adjust the clamping position and strength, which greatly shortens the loading and unloading time. This not only improves transportation efficiency, but also reduces the additional costs caused by long loading and unloading time;

[0042] Avoid scratches: When the support arm 401 clamps the wind turbine tower, the contact area with the tower surface is large and the pressure is uniform. This clamping method avoids scratches on the tower surface caused by excessive or uneven clamping force. At the same time, the design of the tooling and the material selection also ensure that the tower surface will not be damaged, protecting the surface quality of the tower;

[0043] S7: Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, after the wind turbine tower is removed, the hydraulic buffer assembly 3 can be used to control the gravity detection assembly 2 to reset.

[0044] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
