Description

Technical Field

[0001] This application relates to the field of wind turbine tower hoisting technology, and in particular to a wind turbine single-hook turning tool. Background Technology

[0002] The concrete tower is an important component of a wind turbine generator, primarily used to support the top portion of the generator (such as the nacelle and blades). The top ring of the tower typically requires a flipping operation during manufacturing and installation.

[0003] In related technologies, the tilting mechanism usually requires two lifting points for tilting, that is, one is used as a fixed point and the other is used as a lifting point for tilting. The tilting and lifting of the tower is completed by the cooperation of two cranes.

[0004] However, setting up two cranes to flip the tower increases operating costs, and the flipping mechanism makes the flipping process unstable when the tower's center of gravity changes, posing an impact risk. Utility Model Content

[0005] This application provides a wind turbine single-hook turning fixture to solve the problems in related technologies where two cranes are used to turn the tower, which increases the working cost and causes instability in the turning process when the tower's center of gravity changes, posing an impact risk.

[0006] This application provides a wind turbine single-hook turning fixture for turning over towers. The wind turbine single-hook turning fixture includes:

[0007] Fixture;

[0008] The rotating platform includes a horizontal plate and a vertical plate. The horizontal plate is rotatably connected to the fixed frame and is used to place the tower. The vertical plate is located at one end of the horizontal plate, and the rotation axis of the horizontal plate is located on the side away from the vertical plate at the midpoint of the horizontal plate along its length.

[0009] In one possible implementation, the rotating platform has a hoisting position and a tilting position.

[0010] When the rotating platform is in the hoisting position, the horizontal plate is in a horizontal state and the vertical plate is in a vertical state;

[0011] When the rotating platform is in the flipped position, the horizontal plate is between a horizontal and a vertical state, and the vertical plate is between a horizontal and a vertical state.

[0012] In one possible implementation, the rotating platform has a hoisting position and a tilting position.

[0013] When the rotating platform is in the hoisting position, the horizontal plate is in a horizontal state and the vertical plate is in a vertical state;

[0014] When the rotating platform is in the flipped position, the horizontal plate is in a vertical state and the vertical plate is in a horizontal state.

[0015] In one possible implementation, the side wall of the fixing frame facing the vertical plate and the side of the horizontal plate opposite to the vertical plate and opposite to the rotation axis of the horizontal plate together form a flipping space.

[0016] The tilting space is used to rotate the platform from the hoisting position to the tilting position.

[0017] In one possible implementation, the fixing frame includes a base plate and a vertical frame, the lower end of the vertical frame being connected to the base plate, and the horizontal plate being rotatably connected to the vertical frame.

[0018] The vertical frame's sidewall facing the vertical plate, the upper surface of the bottom plate on one side of the vertical frame, and the lower surface of the horizontal plate on one side of the vertical frame enclose and form a flipping space.

[0019] In one possible implementation, the system further includes a rotating member and a limiting member. The rotating member is rotatably mounted on the fixed frame, and the transverse plate is rotatably connected to the rotating member. The limiting member is mounted on the fixed frame and is used to restrict the rotation of the rotating member.

[0020] In one possible implementation, the limiting component includes a limiting pin, a fixing seat is provided on the fixing frame, and a connecting plate is provided on the lower surface of the transverse plate. When the rotating platform is in the hoisting position, the limiting pin passes through the fixing seat and the connecting plate to fix the rotating platform in the hoisting position; and / or,

[0021] The limiting component includes a stop block, which is mounted on a fixed frame. When the rotating platform is in the flip position, the vertical plate abuts against the stop block to fix the rotating platform in the flip position.

[0022] In one possible implementation, the transverse plate can be adjusted along its transverse length; or...

[0023] Multiple wooden blocks are provided on the upper surface of the horizontal plate, and these wooden blocks abut against the tower.

[0024] In one possible implementation, the fixing frame is provided with reinforcing ribs, one end of which is connected to the base plate and the other end of which is connected to the vertical frame.

[0025] In one possible implementation, a ladder is also included, one end of which is connected to the base plate, and the other end of which is used to extend into the tower and abut against the tower.

[0026] This application provides a wind turbine single-hook turning fixture. Through the rotational connection between the horizontal plate and the fixed frame, a stable trajectory is provided for the tower's turning, ensuring a controllable turning process. A vertical plate is positioned at one end of the horizontal plate, not only positioning the tower and preventing slippage during turning, but also enhancing the overall structural strength of the rotating platform and improving the load-bearing capacity of the wind turbine single-hook turning fixture. Because the rotation axis is eccentrically designed and located on the side furthest from the vertical plate along the length of the horizontal plate, a gravity difference exists on both sides of the horizontal plate. This gravity difference can be used to assist movement during turning, reducing the power required by the drive device and lowering energy consumption. Simultaneously, the gravity assistance makes the turning process less strenuous and reduces operational difficulty. The entire device's structural design revolves around the tower's turning function. The coordination of various components, such as the horizontal plate's load-bearing capacity, the vertical plate's positioning, and the eccentric shaft's rotation, efficiently meets the tower's turning requirements from one posture to another, making it suitable for posture adjustment operations in tower manufacturing, installation, and other scenarios.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0038] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0039] Tilting mechanisms typically require two lifting points for tilting, with one serving as a fixed point and the other as a lifting point. The tilting and hoisting of the tower is accomplished through the cooperation of two cranes. However, using two cranes to tilt the tower increases operating costs, and the tilting mechanism can cause instability during the tilting process when the tower's center of gravity changes, posing a risk of impact.

[0040] In view of this, this application provides a wind turbine single-hook turning fixture. Through the rotational connection between the horizontal plate and the fixed frame, a stable motion trajectory is provided for the tower's turning, ensuring a controllable turning process. The vertical plate, located at one end of the horizontal plate, not only positions the tower to prevent slippage during turning but also enhances the overall structural strength of the rotating platform and improves the load-bearing capacity of the wind turbine single-hook turning fixture. Because the rotation axis is eccentrically designed and located on the side furthest from the vertical plate along the length of the horizontal plate, a gravity difference exists on both sides of the horizontal plate. This gravity difference can be used to assist movement during turning, reducing the power required by the drive device and lowering energy consumption. Simultaneously, the gravity assistance makes the turning process less strenuous and reduces operational difficulty. The entire device's structural design revolves around the tower's turning function. The coordination of various components, such as the horizontal plate's load-bearing capacity, the vertical plate's positioning, and the eccentric shaft's rotation, efficiently meets the tower's turning requirements from one posture to another, making it suitable for posture adjustment operations in tower manufacturing, installation, and other scenarios.

[0041] The wind turbine single-hook turning tool provided in the embodiments of this application will be described below with reference to the accompanying drawings.

[0042] like Figure 1 and Figure 2 As shown, the wind turbine single-hook turning fixture of this embodiment is used to turn the tower 10. The wind turbine single-hook turning fixture includes a fixed frame 100 and a rotating platform 200.

[0043] The rotating platform 200 includes a horizontal plate 210 and a vertical plate 220. The horizontal plate 210 is rotatably connected to the fixed frame 100 and is used to place the tower 10. The vertical plate 220 is located at one end of the horizontal plate 210, and the rotation axis of the horizontal plate 210 is located on the side away from the vertical plate 220 at the midpoint of the horizontal plate 210 along its length. The rotatable connection between the horizontal plate 210 and the fixed frame 100 allows relative rotation between them, ensuring the rotating platform 200 can perform a flipping motion, thereby achieving the flipping of the tower. The vertical plate 220 is fixedly installed at the end of the horizontal plate 210, forming an L-shaped or similar rotating platform structure.

[0044] The axis of rotation of the transverse plate 210 is the center line around which the transverse plate 210 rotates about the fixed frame 100. The midpoint of the transverse plate 210 along its length is the middle position of the transverse plate along its length. The side away from the vertical plate 220 defines the position of the axis of rotation relative to the midpoint and the vertical plate 220.

[0045] In this application, the horizontal plate 210 is in a horizontal or near-horizontal state, and the tower 10 is placed on the horizontal plate 210. Since the vertical plate 220 is located at one end of the horizontal plate 210, one end of the tower 10 can abut or approach the vertical plate 220 to achieve initial positioning and prevent the tower from sliding along the length of the horizontal plate 210 during initial placement. Under the action of external force, the horizontal plate 210 begins to rotate around its rotation axis connected to the fixing frame 100. Since the rotation axis is located on the side away from the vertical plate 220 from the midpoint of the length of the horizontal plate 210, that is, the rotation axis is biased towards the end of the horizontal plate 210 where the vertical plate is not located, an eccentric structure is formed. During rotation, the horizontal plate 210 drives the tower 10 and the vertical plate 220 placed on it to rotate together. Due to the eccentric design, the gravity distribution on both sides of the horizontal plate 210 is uneven. The side closer to the vertical plate 220 has a larger gravity due to the presence of the tower 10 and the vertical plate 220. During rotation, this gravity difference can be used to assist in flipping, reducing the need for external driving force. As the horizontal plate 210 rotates, the attitude of the tower 10 gradually changes, transforming from an initial horizontal state to a target attitude such as a vertical state. When the horizontal plate 210 rotates to a preset angle, the tower 10 reaches the required flipping attitude, and the flipping process is completed.

[0046] The rotatable connection between the transverse plate 210 and the fixed frame 100 provides a stable trajectory for the tower 10's rotation, ensuring a controllable rotation process. The vertical plate 220, located at one end of the transverse plate 210, not only positions the tower 10 to prevent slippage during rotation but also enhances the overall structural strength of the rotating platform 200, improving the load-bearing capacity of the wind turbine single-hook rotation fixture. Because the rotation axis is eccentrically designed and located on the side of the transverse plate 210 away from the vertical plate 220 along its length, a gravity difference exists on both sides of the transverse plate 210. This gravity difference can be used to assist movement during rotation, reducing the power required by the drive device and lowering energy consumption. Simultaneously, the gravity assistance makes the rotation process less strenuous and reduces operational difficulty. The entire device's structural design revolves around the tower 10's rotation function. The coordination of components, such as the transverse plate 210's load-bearing capacity, the vertical plate 220's positioning, and the eccentric shaft's rotation, efficiently meets the tower 10's rotation requirements from one posture to another, making it suitable for posture adjustment operations in tower 10 manufacturing and installation scenarios.

[0047] like Figure 1 and Figure 2 As shown, in some embodiments, the rotating platform 200 has a hoisting position and a flipping position. When the rotating platform 200 is in the hoisting position, the horizontal plate 210 is in a horizontal state and the vertical plate 220 is in a vertical state. When the rotating platform 200 is in the flipping position, the horizontal plate 210 is between a horizontal state and a vertical state, and the vertical plate 220 is between a horizontal state and a vertical state.

[0048] In this application, the rotating platform 200 is in the hoisting position. At this time, the horizontal plate 210 is horizontal, providing a stable bearing surface for the hoisting and placement of the tower 10. The vertical plate 220 is vertical. When the tower 10 is hoisted onto the horizontal plate 210, one end of the tower 10 can abut against the vertical plate 220. The vertical posture of the vertical plate 220 is used to effectively position the tower 10, preventing the tower 10 from sliding during placement and ensuring the safety and accuracy of the hoisting operation.

[0049] Under the action of a drive device such as a crane, the rotating platform 200 begins to rotate around the rotation axis of the horizontal plate 210 and the fixed frame 100, gradually moving away from the hoisting position and entering the flipping process. As the rotating platform 200 rotates, the horizontal plate 210 begins to tilt from a horizontal state, and the vertical plate 220 also gradually tilts from a vertical state. Due to the eccentric design of the rotation axis, the weight distribution on both sides of the horizontal plate 210 is uneven. The side closer to the vertical plate 220 has a larger weight, which includes the weight of the tower 10 and the vertical plate 220 itself. This weight helps to propel the rotating platform 200 to continue rotating, reducing the power required by the drive device.

[0050] When the rotating platform 200 is in the flipped position, both the horizontal plate 210 and the vertical plate 220 are tilted between horizontal and vertical states. At this time, the tower 10 tilts along with the horizontal plate 210, its attitude constantly changing, gradually approaching the target flipped posture. During this process, the vertical plate 220 still provides a certain degree of restraint on the tower 10, preventing it from slipping off the horizontal plate 210 while tilted, thus ensuring the stability of the flipping process. If further flipping is required, the rotating platform can continue to rotate, always maintaining its posture within the flipped position range, until the final flipping target is reached.

[0051] It should be noted that, in the hoisting position, the horizontal state of the horizontal plate 210 provides a flat and stable foundation for the hoisting and placement of the tower 10, reducing the difficulty of hoisting alignment. The vertical state of the vertical plate 220 effectively positions the tower 10, preventing it from swaying or shifting during hoisting, thus improving hoisting efficiency and safety. The flipping position clarifies that the horizontal plate 210 and vertical plate 220 are in an inclined state. In this state, the center of gravity of the tower 10 gradually shifts, and with the gravity assistance of the eccentric structure, the flipping process becomes more stable. Simultaneously, the vertical plate 220, even in the inclined state, still functions as a limiting device, preventing the tower 10 from slipping during flipping and ensuring the controllability of the flipping process. By clearly defining the different states of the hoisting and flipping positions, this wind power single-hook flipping fixture can clearly adapt to the two key operational stages of tower 10 hoisting and flipping, meeting the needs of the entire process from placement to attitude adjustment of the tower 10, and improving the adaptability and practicality of the device in practical applications.

[0052] like Figure 1 and Figure 2 As shown, in some embodiments, the rotating platform 200 has a hoisting position and a flipping position. When the rotating platform 200 is in the hoisting position, the horizontal plate 210 is in a horizontal state and the vertical plate 220 is in a vertical state. When the rotating platform 200 is in the flipping position, the horizontal plate 210 is in a vertical state and the vertical plate 220 is in a horizontal state.

[0053] In this application, the rotating platform 200 maintains the hoisting position, and the horizontal plate 210 is placed horizontally, providing a bearing surface parallel to the ground for the tower 10, facilitating the stable placement of the tower 10 by the hoisting equipment. The vertical plate 220 stands vertically, forming a vertical angle with the horizontal plate 210. One end of the tower 10 is in contact with the vertical plate 220, and its vertical posture restricts the sliding of the tower 10 along the length direction of the horizontal plate 210, ensuring accurate hoisting positioning. The drive device drives the rotating platform 200 to rotate around the eccentric axis, and the horizontal plate 210 gradually flips upward from a horizontal state, while the vertical plate 220 gradually flips downward from a vertical state. Because the rotation axis deviates from the midpoint of the horizontal plate 210 and is closer to the end without the vertical plate 220, the gravitational moment on the side where the tower 10 and the vertical plate 220 are located is greater than that on the other side, forming a gravity assist and reducing drive energy consumption.

[0054] During this process, the horizontal plate 210 and the vertical plate 220 maintain a vertical relationship, jointly constraining the tower 10 to rotate synchronously. When the rotating platform 200 completes a 90° rotation and reaches the rotation position, the horizontal plate 210 is in a vertical state, and the tower 10 becomes upright accordingly, achieving a change in posture from horizontal to vertical. The vertical plate 220 is in a horizontal state, which may be in contact with the ground or supporting structure, providing additional stable support for the vertical horizontal plate 210 and the tower 10, preventing them from tipping over.

[0055] It should be noted that the flipping position is specifically defined as the endpoints where the horizontal plate 210 is vertical and the vertical plate 220 is horizontal, ensuring that the tower can be accurately flipped to 90° to avoid subsequent installation difficulties caused by angular deviations. The gravity assistance of the eccentric structure further shortens the flipping time and improves work efficiency. The combination of the horizontal plate 210 and the vertical plate 220 at the hoisting position reduces the risk of slippage during the hoisting of the tower 10. After flipping, the horizontal vertical plate 220 can serve as an auxiliary support, working with the fixing frame 100 to distribute the gravitational load of the tower 10 when it is upright, reducing the risk of structural deformation. The horizontal plate 210 and the vertical plate 220 always maintain a vertical relationship, forming a stable L-shaped constraint frame during the flipping process, ensuring that the attitude of the tower 10 and the rotating platform 200 are synchronously transformed, avoiding relative slippage.

[0056] like Figure 1 and Figure 2 As shown, in some embodiments, the sidewall of the fixing frame 100 facing the vertical plate 220 and the side of the horizontal plate 210 opposite to the vertical plate 220 and opposite to the rotation axis of the horizontal plate 210 together form a flipping space 310. The flipping space 310 is used to rotate the platform 200 from the hoisting position to the flipping position.

[0057] In this application, when the rotating platform 200 is in the hoisting position, the horizontal plate 210 is placed horizontally, and the vertical plate 220 is erected vertically at one end of the horizontal plate 210. At this time, the side wall of the fixing frame 100 facing the vertical plate 220 is in a fixed position, and the side of the horizontal plate 210 away from the vertical plate 220 and away from the rotation axis is located at the horizontal end away from the vertical plate 220. The flipping space 310 enclosed by both is in its initial state, with no obstructions inside, providing sufficient margin for the flipping of the rotating platform 200. The tower 10 is placed stably on the horizontal plate 210, and the vertical plate 220 limits its movement. The driving device drives the horizontal plate 210 to rotate around the rotation axis, and the rotating platform 200 begins to switch from the hoisting position to the flipping position.

[0058] As the horizontal plate 210 rotates, the side of it facing away from the vertical plate 220 and the axis of rotation gradually rotates. Throughout the switching process, all moving parts of the rotating platform 200, the horizontal plate 210 and the vertical plate 220, rotate within the flipping space 310. The side wall of the fixing frame 100 serves as a fixed boundary, preventing the rotating platform 200 from excessively shifting towards the inward side of the fixing frame 100. When the rotating platform 200 completes the flipping action, with the horizontal plate 210 in a vertical state and the vertical plate 220 in a horizontal state, the entire platform remains within the flipping space 310, and the spatial boundary always provides a safety constraint.

[0059] like Figure 2 As shown, in some embodiments, the fixing frame 100 includes a base plate 110 and a vertical frame 120. The lower end of the vertical frame 120 is connected to the base plate 110, and the horizontal plate 210 is rotatably connected to the vertical frame 120. The side wall of the vertical frame 120 facing the vertical plate 220, the upper surface of the base plate 110 located on one side of the vertical frame 120, and the lower surface of the horizontal plate 210 located on one side of the vertical frame 120 enclose a flipping space 310.

[0060] In this application, the rotating platform 200 is in the hoisting position, the horizontal plate 210 is horizontal, and there is a certain distance between its lower surface and the upper surface of the bottom plate 110 on one side of the vertical frame 120. The side wall of the vertical frame 120 facing the vertical plate 220, the upper surface of the corresponding bottom plate 110, and the lower surface of the horizontal plate 210 together enclose the initial flipping space 310. At this time, the tower 10 is hoisted and placed on the horizontal plate 210, and the vertical plate 220 plays a positioning role for the tower 10.

[0061] Driven by an external force, the horizontal plate 210 begins to rotate around its rotational connection point with the vertical frame 120, changing from a horizontal to a vertical state. During rotation, the lower surface of the horizontal plate 210 gradually approaches the upper surface of the base plate 110, and the shape and size of the flipping space 310 dynamically change with the rotation of the horizontal plate. Since the flipping space 310 is enclosed by relevant parts of the fixed frame 100, its boundaries limit the range of motion of the rotating platform, ensuring that the horizontal plate 210 and the vertical plate 220 do not interfere with other parts of the fixed frame 100 during flipping. When the rotating platform 200 reaches the flipping position, the horizontal plate 210 is in a vertical state, and the vertical plate 220 is in a horizontal state. At this time, the lower surface of the horizontal plate 210 is in contact with or maintains a certain gap with the upper surface of the base plate 110, and the entire flipping process is safely completed within the flipping space 310.

[0062] It should be noted that the fixed frame 100 can prevent the rotating platform 200 from colliding or interfering with the fixed frame 100 during the process of switching from the hoisting position to the tilting position, ensuring smooth tilting operation. The fixed frame 100 is composed of a base plate 110 and a vertical frame 120. The base plate 110 provides a stable bottom support, while the vertical frame 120 serves as the rotation fulcrum of the horizontal plate 210. The connection between the two enhances the overall structural strength of the fixed frame 100, enabling it to withstand the gravitational load of the rotating platform 200 and the tower 10, ensuring the stability of the device during the tilting process.

[0063] like Figure 2 and Figure 3 As shown, in some embodiments, a rotating member 320 and a limiting member 330 are also included. The rotating member 320 is rotatably mounted on the fixed frame 100, and the transverse plate 210 is rotatably connected to the rotating member 320. The limiting member 330 is mounted on the fixed frame 100 and is used to limit the rotation of the rotating member 320.

[0064] In this application, when the rotating platform 200 is in the hoisting position, the horizontal plate 210 is placed horizontally, and the rotating component 320 is in its initial rotating position on the fixed frame 100. The limiting component 330 restricts the rotating component 320. At this time, the tower 10 is placed on the horizontal plate 210, and the vertical plate 220 limits the tower 10, and the entire device is in a stable hoisting preparation state. The driving device drives the horizontal plate 210 to rotate. Since the horizontal plate and the rotating component 320 are rotatably connected, the rotating component 320 rotates synchronously on the fixed frame 100 with the movement of the horizontal plate 210. During the rotation, the rotating component 320 acts as an intermediate transmission component, smoothly transmitting the rotation of the horizontal plate 210, while rotating itself around the rotation axis of the fixed frame 100, making the flipping action of the horizontal plate 210 smoother. When the rotating platform 200 switches from the hoisting position to the flipping position within the flipping space 310, the rotating component 320 continues to rotate. When the rotating platform 200 reaches the flipping position where the horizontal plate 210 is vertical and the vertical plate 220 is horizontal, the limiting member 330 is activated, restricting the rotating member 320 and preventing it from continuing to rotate. This ensures that the rotating platform 200 remains stably in the flipping position, preventing the tower 10 from shifting its posture due to accidental rotation. If it is necessary to reverse the flipping position to return to the hoisting position, the limiting member 330 is released from restricting the rotating member 320. The drive device then drives the horizontal plate 210 to rotate in the opposite direction, and the rotating member 320 moves in the opposite direction until it returns to its initial position.

[0065] It should be noted that the rotating component 320, as an intermediate rotating part between the transverse plate 210 and the fixed frame 100, optimizes the rotating connection structure, reduces friction and jamming that may occur with direct rotating connections, makes the flipping action of the transverse plate 210 smoother, and reduces the risk of swaying of the tower 10 during the flipping process. Through the limiting action of the limiting component 330, the device can not only complete the full flipping from the hoisting position to the flipping position, but also fix the rotating platform 200 in the hoisting or flipping position, improving the functional flexibility of the device and thus extending its overall service life.

[0066] like Figure 2 As shown, in some embodiments, the limiting member 330 includes a limiting pin 331, a fixing seat is provided on the fixing frame 100, and a connecting plate is provided on the lower surface of the transverse plate 210. When the rotating platform 200 is in the hoisting position, the limiting pin 331 passes through the fixing seat and the connecting plate to fix the rotating platform 200 in the hoisting position.

[0067] In this application, when the rotating platform 200 is in the hoisting position, the horizontal plate 210 is placed horizontally, and the connecting plate on the lower surface of the horizontal plate is aligned with the fixing seat hole on the fixing frame 100. At this time, the limiting pin 331 is inserted into the corresponding hole of the fixing seat and the connecting plate. The pin restricts the relative movement between the connecting plate and the fixing seat through mechanical cooperation, thereby preventing the horizontal plate 210 from rotating, so that the rotating platform is stably fixed in the hoisting position, ensuring that the device does not shake when the tower 10 is hoisted. If it is necessary to start the rotation, the limiting pin 331 is pulled out to release the fixation, and the rotating platform can start to rotate under the action of the drive device.

[0068] like Figure 2 and Figure 3 As shown, in some embodiments, the limiting member 330 includes a stop block 332, which is disposed on the fixed frame 100. When the rotating platform 200 is in the flip position, the vertical plate 220 abuts against the stop block 332 to fix the rotating platform 200 in the flip position.

[0069] When the rotating platform 200 rotates to the flipped position, the horizontal plate 210 is in a vertical state, and the vertical plate 220 is in a horizontal state and rotates towards the fixed frame 100. Finally, the vertical plate 220 abuts against the stop block 332 fixed to the fixed frame. The stop block 332, through its rigidity, prevents the vertical plate 220 from continuing to rotate, thereby limiting the movement of the entire rotating platform and keeping it stably fixed in the flipped position, preventing the tower 10 from shifting its posture due to accidental force. If a reverse flip is required, the drive device provides reverse power, causing the vertical plate 220 to disengage from the stop block 332, and the rotating platform 200 can then return to the hoisting position.

[0070] If both the limiting pin 331 and the stop block 332 are used, the device is fixed in the hoisting position by the limiting pin 331 and in the flipping position by the stop block 332. The two methods work together to provide double protection at two key positions, further improving the stability of the device.

[0071] In some embodiments, the transverse plate 210 can be adjusted along its transverse length. The limiting pin 331 cooperates with the fixed seat and the connecting plate, and the stop block 332 cooperates with the vertical plate 220. Both utilize the original structure of the device, including the transverse plate 210, the vertical plate 220, and the fixed frame 100, to achieve limiting, making the overall structure more compact. Together with the rotating component 320 and other components, they form a complete rotation and limiting mechanism, improving the overall stability of the device.

[0072] When the transverse plate 210 needs to be adjusted according to the length of the tower 10, its length is changed laterally through its own length adjustment structure, such as an expansion joint or splicing structure. After adjustment to match the length of the tower 10, the transverse plate 210 is fixed at that length. At this point, the tower 10 is placed on the transverse plate 210, and the length of the transverse plate 210 is sufficient to fully support the tower 10, preventing the tower 10 from being suspended at both ends due to the transverse plate 210 being too short. During subsequent hoisting and tilting processes, the appropriately sized transverse plate 210 provides stable support for the tower 10, ensuring the stability of the tower 10's posture.

[0073] like Figure 2 and Figure 3 As shown, in some embodiments, the upper surface of the transverse plate 210 is provided with a plurality of wooden blocks 340, which abut against the tower 10.

[0074] In this application, multiple wooden blocks 340 are installed on the upper surface of the transverse plate 210. The positions of the wooden blocks 340 can be arranged according to the outer contour of the tower 10. When the tower 10 is placed on the transverse plate 210, the multiple wooden blocks 340 abut against the outer surface of the tower 10. Because the wooden blocks 340 have a certain degree of elasticity and toughness, they can adapt to the curvature of the outer surface of the tower 10, making the contact between the tower 10 and the transverse plate 210 more intimate. During hoisting, the wooden blocks 340 can reduce the friction between the tower 10 and the transverse plate 210, preventing the surface of the tower 10 from being scratched. During the flipping process, the wooden blocks 340 can buffer the impact force generated by the shaking of the tower 10, while increasing the friction between the tower 10 and the transverse plate 210, preventing the tower 10 from sliding.

[0075] like Figure 2 As shown, in some embodiments, the fixing frame 100 is provided with a reinforcing rib 350, one end of the reinforcing rib 350 is connected to the base plate 110, and the other end of the reinforcing rib 350 is connected to the vertical frame 120.

[0076] In this application, the reinforcing rib 350 connects the base plate 110 and the vertical frame 120, forming a stable triangular support structure. Utilizing the stability principle of a triangle, this significantly enhances the overall rigidity and deformation resistance of the fixed frame 100, enabling it to withstand greater loads, including the weight of the tower and the dynamic impact force during tilting, thus preventing the fixed frame 100 from bending, tilting, or other damage under stress. The reinforcing rib 350 enhances the rigidity of the fixed frame 100, ensuring that the rotating platform 200 does not experience additional attitude deviations due to the swaying of the fixed frame 100 during tilting, and guaranteeing that the tower 10 can accurately and smoothly switch from the hoisting position to the tilting position.

[0077] like Figure 4As shown, in some embodiments, a ladder 360 is also included, one end of which is connected to the base plate 110, and the other end of which is used to extend into the tower 10 and abut against the tower 10.

[0078] In this application, the ladder 360 provides a direct and safe passage for personnel to enter the tower 10, eliminating the need for additional temporary scaffolding or high-altitude work equipment, thus reducing the difficulty of operations and improving the efficiency of internal tower inspection and installation. During the rotation process, one end of the ladder 360 is fixed to the base plate 110, while the other end abuts against the tower 10, forming an additional support point that limits the radial sway of the tower 10. Combined with the constraints of the horizontal plate 210 and the vertical plate 220, this reduces the risk of structural damage caused by swaying. The connection between the ladder 360 and the base plate 110 does not affect the function of other components of the fixing frame 100, such as the reinforcing rib 350 and the vertical frame 120, and its contact with the tower 10 does not interfere with the rotation of the rotating platform 200, improving the overall convenience and safety of the operation.
