Description

Technical Field

[0001] This invention relates to the field of concrete towers, and in particular to a precast segment assembly platform for concrete towers. Background Technology

[0002] Concrete towers are a crucial component of wind turbine generators, primarily responsible for supporting the structure and ensuring the stability of the entire system. They offer advantages such as high structural stability, high rigidity, and minimal transportation limitations. Concrete towers are often used in conjunction with steel towers to form a hybrid tower system. This design not only reduces overall construction costs but also improves structural reliability and durability. Due to the inherent rigidity and strength of concrete, concrete towers are particularly suitable for applications requiring strong wind loads, thus ensuring the safe operation of the wind turbine. Specifically, wind turbine towers are typically very tall, sometimes reaching hundreds of meters. To facilitate transportation and assembly, these towers are usually manufactured and installed in multiple sections. This design also accelerates construction progress and further reduces construction costs.

[0003] When hoisting precast concrete tower segments, they need to be assembled in rings. During the ring assembly process, the key to improving the hoisting speed of concrete towers is how to quickly adjust the joints between segments to ensure that the arc bolts connecting the segments can be easily drilled. The traditional method is to use a crane to adjust the relative position of the segments, which is relatively slow and not convenient for positioning and limiting segments with different inner diameters. During hoisting, the assembly platform is fixed, making it difficult to adjust according to the assembly angle and adapt the hoisting equipment to the assembly platform, which is time-consuming and labor-intensive. Therefore, we propose a precast concrete tower segment assembly platform to solve the problems mentioned above. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention provides a precast concrete tower segment assembly platform, which solves the problems mentioned in the background section regarding existing precast concrete tower segment assembly platforms. During hoisting, precast concrete tower segments need to be assembled in rings. A key challenge in improving the hoisting speed of concrete towers is how to quickly adjust the joints between segments to ensure smooth drilling of the connecting arc bolts. Traditionally, cranes are used to adjust the relative positions of the segments, which is relatively slow and inconvenient for positioning and defining segments with different inner diameters. Furthermore, the fixed assembly platform during hoisting makes it difficult to adjust the hoisting equipment to adapt to the assembly angle, resulting in time-consuming and labor-intensive technical problems.

[0005] To solve the above technical problems, the present invention provides the following technical solution: a precast concrete tower segment assembly platform, comprising: a circular track, support beams, a servo motor, and a drive motor. The circular track is ring-shaped, with a circular groove at its inner end and a bottom fixing frame fixedly installed at its outer end. Eight support beams are evenly distributed along one ring of the circular track. A hydraulic jack is fixedly installed at the lower end of each support beam, and a support base is fixedly installed at the lower end of each hydraulic jack. A metal wheel is rotatably mounted on the inner end of the support base. The metal wheel is located inside the circular groove. A threaded screw is fixedly installed at the output end of the servo motor. An arc-shaped limiting plate is threadedly connected to the outer end of the threaded screw. A mounting plate is threadedly connected to the outer end of the threaded screw. An electric telescopic rod is fixedly installed on the outer surface of the mounting plate. An arc-shaped reinforcing plate is fixedly installed at the output end of the electric telescopic rod. The electric telescopic rod and the arc-shaped reinforcing plate are located on the upper side of the support beam and the rectangular groove for clamping and limiting the tube segment. A central mounting shaft is fixedly installed on the output shaft of the drive motor. The support beam is engaged and installed on the outer end of the central mounting shaft.

[0006] As a preferred embodiment of the present invention, eight hydraulic jacks are provided to adjust the support beam for easy segment assembly.

[0007] As a preferred embodiment of the present invention, a servo motor is fixedly installed at the inner end of the support beam to accommodate segments with different inner diameters.

[0008] As a preferred embodiment of the present invention, the lower ends of the arc-shaped limiting plate and the mounting plate are both engaged and installed at the inner end of the rectangular groove, and the threaded screw is rotatably installed inside the rectangular groove.

[0009] As a preferred embodiment of the present invention, the drive motor is fixedly installed on the upper end of the bottom fixing frame, and the bottom fixing frame and the lower surface of the circular track are on the same horizontal line.

[0010] Compared with the prior art, the beneficial effects that this invention can achieve are:

[0011] 1. By setting up hydraulic jacks, the hydraulic jacks can drive the outer end of the support beam to rise and fall, adjust the entire assembly platform, and then adjust the joint of the segments, so as to facilitate the rapid assembly of precast concrete tower segments.

[0012] 2. During hoisting, the tunnel segment falls between the arc-shaped limiting plate and the arc-shaped reinforcing plate. Then, the electric telescopic rod pushes the arc-shaped reinforcing plate to clamp the tunnel segment, which makes the tunnel segment have sufficient space to descend, improves the operation efficiency, and ensures a stable clamping.

[0013] 3. The servo motor drives the arc-shaped limiting plate and the mounting plate to move at the inner end of the support beam through the threaded screw, which can be applied to pipe segments of different diameters and adjust automatically and quickly;

[0014] 4. During hoisting, if the hoisting equipment is located on the other side of the tunnel segment to be assembled, in order to reduce the difficulty and time of hoisting, the support beam can be rotated by the drive motor, so that the metal wheel at the inner end of the support seat rotates at the inner end of the circular groove. This makes it easy to adjust the angle of the support beam according to the progress of tunnel segment assembly, thereby reducing the difficulty and time of hoisting. Attached Figure Description

Detailed Implementation

[0022] To make the technical means, creative features, objectives, and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Example

[0023] Please refer to Figure 1-6As shown, the present invention provides a technical solution: a precast concrete tower segment assembly platform;

[0024] The circular track 1 is in the shape of a ring. The inner end of the circular track 1 is provided with a circular groove 5. The outer end of the circular track 1 is fixedly installed with a bottom fixing frame 6, which facilitates the adjustment of the angle of the support beam 2 according to the progress of the segment assembly, thereby reducing the difficulty and time of hoisting.

[0025] A hydraulic jack 7 is fixedly installed at the lower end of the support beam 2. The hydraulic jack 7 allows the outer end of the support beam 2 to be raised and lowered, adjusting the entire assembly platform and thus the joints of the tunnel segments. This facilitates the rapid assembly of precast concrete tower segments. A support base 8 is fixedly installed at the lower end of the hydraulic jack 7, and a metal wheel 9 is rotatably installed at the inner end of the support base 8. Eight support beams 2 are evenly distributed along a circle of track 1. The eight hydraulic jacks 7 are used to adjust the support beams 2 to facilitate segment assembly. The lower end of the support base 8 is located inside the circular groove 5, and the metal wheel 9 is located inside the circular groove 5, allowing the segment assembly position to align with the hoisting equipment, saving time and reducing operational difficulty.

[0026] A threaded screw 11 is fixedly installed at the output end of the servo motor 3. An arc-shaped limiting plate 12 is threadedly connected to the outer end of the threaded screw 11, and an mounting plate 13 is threadedly connected to the outer end of the threaded screw 11. This is suitable for pipe segments of different diameters and allows for automatic and rapid adjustment. An electric telescopic rod 14 is fixedly installed on the outer surface of the mounting plate 13. An arc-shaped reinforcing plate 15 is fixedly installed at the output end of the electric telescopic rod 14. The servo motor 3 is fixedly installed at the inner end of the support beam 2 to accommodate pipe segments of different inner diameters. The lower ends of the arc-shaped limiting plate 12 and the mounting plate 13 are both engaged and installed at the inner end of the rectangular groove 10. The threaded screw 11 is rotatably installed inside the rectangular groove 10. The electric telescopic rod 14 and the arc-shaped reinforcing plate 15 are located on the upper side of the support beam 2 and the rectangular groove 10 to clamp and limit the pipe segments, ensuring sufficient space for the pipe segments to descend, improving operating efficiency, and providing a stable clamping.

[0027] The output shaft of the drive motor 4 is fixedly mounted with a central mounting shaft 16, and the support beam 2 is engaged with the outer end of the central mounting shaft 16. The drive motor 4 is fixedly mounted on the upper end of the bottom fixing frame 6, and the bottom fixing frame 6 is on the same horizontal line as the lower surface of the circular track 1. The drive motor 4 can drive the support beam 2 to rotate, so that the metal wheel 9 at the inner end of the support seat 8 rotates at the inner end of the circular groove 5. This facilitates the adjustment of the angle of the support beam 2 according to the progress of the segment assembly, reducing the difficulty and time of hoisting.

[0028] Specific working principle:

[0029] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, when using the precast concrete tower segment assembly platform, the circular track 1 is placed at the desired location. The segment is then hoisted onto the upper side of the support beam 2 using hoisting equipment. With the support and guidance of the staff, the lower end of the segment is placed between the arc-shaped limiting plate 12 and the arc-shaped reinforcing plate 15. Then, the electric telescopic rod 14 on the mounting plate 13 pushes the arc-shaped reinforcing plate 15 towards the arc-shaped limiting plate 12 to clamp and limit the segment. Through the operation control system, each hydraulic jack 7 is raised and lowered. The raising and lowering of the hydraulic jack 7 drives the outer end of the support beam 2 to rise and fall. The raising and lowering of the outer end of the support beam 2 can adjust the misalignment of the precast concrete tower segment joints, increase the segment assembly speed, and enable real-time and rapid adjustment of the precast concrete tower segment assembly platform, facilitating the rapid assembly of the precast concrete tower segments.

[0030] like Figure 1 , Figure 3 and Figure 5 As shown, due to the different upper and lower diameters of the wind turbine tower, when assembling segments of other diameters, the servo motor 3 at the inner end of the support beam 2 is activated. When the output end of the servo motor 3 rotates, it drives the threaded screw 11 to rotate at the inner end of the rectangular groove 10. Because the lower ends of the mounting plate 13 and the arc-shaped limiting plate 12 are engaged at the inner end of the rectangular groove 10, when the threaded screw 11 rotates, the mounting plate 13 and the arc-shaped limiting plate 12 move at the inner end of the rectangular groove 10. When the required position size is reached, the threaded screw 11 stops rotating, and then the assembly operation can continue.

[0031] like Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, during assembly, when the hoisting equipment is located on the other side of the segment to be assembled, in order to reduce the difficulty and time of hoisting, the drive motor 4 is started. The drive motor 4 at the upper end of the bottom fixed frame 6 drives the support beam 2 to rotate through the central mounting shaft 16, so that the metal wheel 9 at the inner end of the support seat 8 rotates at the inner end of the circular groove 5, so that the segment assembly position meets the hoisting equipment, saving time and reducing the difficulty of operation. It is also convenient to adjust the angle of the support beam 2 according to the progress of segment assembly, reducing the difficulty and time of hoisting. The above completes a series of operations of the precast concrete tower segment assembly platform.
