Description

Technical Field

[0001] This application relates to the field of offshore power technology, and in particular to a tower pipe section transfer device. Background Technology

[0002] In the wind power sector, with the trend towards larger wind turbine generators, the size and weight of the towers in wind turbine generators are also increasing, especially for offshore wind turbine generators. The diameter of offshore wind turbine towers increases with the increase in single-unit capacity, and the current maximum diameter has reached 8.5 meters, which is equivalent to nearly 3 stories high. At the same time, the weight of a single section has also increased from about 20 tons to nearly 30 tons. Currently, many steel structure fabrication plants in China need to make extensive equipment modifications to take on ultra-large diameter tower projects like this. A single sheet of raw steel plate weighs nearly 30 tons. Each steel plate can be processed from entering the factory to cutting, beveling, and rolling within the workshop and can be transferred using bridge cranes. However, the rolled sections are usually stored in a stockyard before being assembled. When the required sections are needed, they are then transferred to the assembly station. However, the diameter difference between the top and bottom sections of the tower is large, ranging from 4 to 8.5 meters. Currently, the transfer of single tower sections is very difficult and requires the use of modular vehicles. However, the limited space for tower components and the difficulty in operating modular vehicles make tower assembly extremely complicated. Summary of the Invention

[0033] To better understand the above technical solutions, the technical solutions of the embodiments of this application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this application and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this application, rather than limitations on the technical solutions of this application. In the absence of conflict, the embodiments of this application and the technical features in the embodiments can be combined with each other.

[0034] like Figure 1 As shown in the figure, this application proposes a tower pipe section transfer device, including: a load-bearing base 110, on which a transfer hole 111 is provided; a lifting device 120, which is disposed on the load-bearing base 110; and a working component 130, which includes a support frame 131, a crossbeam support arm 132, and a hook 133. The support frame 131 is disposed on the lifting device 120, the crossbeam support arm 132 is connected to the support frame 131, one end of the crossbeam support arm 132 is a free end, and the hook 133 is used to connect to the free end of the crossbeam support arm 132.

[0035] The tower section transfer device provided in this application includes a load-bearing base 110, a lifting device 120, and a working component 130. During operation, a single tower section can be hoisted onto the working component 130, and the crossbeam support arm 132 can be inserted into the single tower section, with the crossbeam support arm 132 abutting against the top of the single tower section. Then, by inserting the forklift fork into the transfer hole 111 of the load-bearing base, the tower section transfer device and the single tower section can be moved by the forklift. This configuration enables the transfer of a single tower section.

[0036] The tower section transfer device provided in this application embodiment allows for horizontal splicing of multiple tower sections during tower assembly. By placing a single tower section on the crossbeam support arm 132, the radial direction of the single tower section can be perpendicular to the ground. Based on this, multiple single tower sections can be reciprocated and transported, and the multiple single tower sections can be horizontally spliced ​​together. When it is necessary to install tower accessories, such as installing the lower tower platform, the lower tower platform can be hung on the lower tower platform through the hook 133, so that the lower tower platform can be spliced ​​onto the tower. Based on this, the installation efficiency of tower accessories can be improved, and the assembly efficiency of the tower can be improved.

[0037] The tower section transfer device provided in this application embodiment takes into account the possible differences in diameter between different tower sections or multiple sections of a single tower section. Therefore, the tower section transfer device provided in this application embodiment is equipped with a lifting device 120. The lifting device 120 can drive the working component 130 to rise and fall, thereby adjusting the effective height of the tower section transfer device. When it is necessary to transfer a single tower section with a larger diameter, the lifting device 120 can be used to drive the working component 130 to rise. When it is necessary to transfer a single tower section with a smaller diameter, the lifting device 120 can be used to drive the working component 130 to fall. Based on this, the tower section transfer device provided in this application embodiment can transport single tower sections of different sizes. The single tower section can be transported by a forklift. It is convenient to use, has a wide range of applications, strong versatility, and the hook 133 with auxiliary function is detachable and does not affect the main function of transporting single tower sections. It has low cost and high structural strength.

[0038] like Figure 1 As shown, in one feasible embodiment, the work assembly 130 further includes a work platform 140, which is detachably connected to the support frame 131 and located at one end of the support frame 131 near the crossbeam support arm 132.

[0039] In this technical solution, the working component 130 may also include a working platform 140. By connecting the working platform 140 to the support frame 131, workers can climb onto the working platform 140 to perform high-altitude operations, which facilitates the installation of single tower sections and the assembly of the tower sections.

[0040] It is understood that the tower pipe section transfer device provided in this application embodiment may also include a folding ladder, through which workers can climb onto the work platform 140.

[0041] like Figure 1 As shown, in one feasible embodiment, the work platform 140 includes: a work surface 141; and a suspension assembly 142 connected to the work surface 141 and suspended from the top of the support frame 131.

[0042] In this technical solution, the structural composition of the work platform 140 is further provided. The work platform 140 may include a work surface 141 and a suspension assembly 142. The work surface 141 can be suspended on the support frame 131 by the suspension assembly 142 to facilitate the assembly and disassembly of the work platform 140.

[0043] It is understood that the suspension assembly 142 may include multiple suspension components. By fixing the working surface 141 with multiple suspension components, the stability of the working surface 141 can be improved, making the use of the tower pipe section transfer device safer.

[0044] like Figure 1 As shown, in one feasible embodiment, the load-bearing base 110 further includes multiple hydraulic grooves; the lifting device 120 includes multiple hydraulic rods 121, each hydraulic groove is provided with a hydraulic rod 121, and the hydraulic rods 121 are connected to the support frame 131.

[0045] In this technical solution, the structural composition of the lifting device 120 is further provided. The lifting device 120 may include multiple hydraulic rods 121, and multiple hydraulic grooves may be opened on the load-bearing base 110. Each hydraulic groove may be provided with a hydraulic rod 121. The support frame 131 is connected to the end of the hydraulic rod 121 away from the load-bearing base 110. Based on this, the lifting of the multiple hydraulic rods 121 can drive the lifting of the support frame 131.

[0046] In this technical solution, a lifting device 120 is composed of multiple hydraulic rods 121, and the hydraulic rods 121 are set in a hydraulic groove. This arrangement facilitates the installation, maintenance and replacement of the hydraulic rods 121.

[0047] like Figure 1 As shown, in one feasible embodiment, a insertion hole is formed on the crossbeam support arm 132, and the hook 133 is inserted into the insertion hole.

[0048] In this technical solution, a connection method for the hook 133 is further provided. The hook 133 is connected to the crossbeam support arm 132 by plugging in, which facilitates the disassembly and installation of the hook 133.

[0049] It is understandable that the crossbeam support arm 132 can be a square tube, and the through hole inside the square tube is the insertion hole.

[0050] It is understandable that there can be two crossbeam support arms 132, which are respectively arranged on both sides of the support frame 131. This arrangement can support a single tower section from two points, thereby improving the stability of the support.

[0051] like Figure 1 As shown, in one feasible embodiment, the tower tube section transfer device further includes: a diagonal brace 150, one end of which is connected to the free end of the crossbeam support arm 132, and the other end is connected to the support frame 131.

[0052] In this technical solution, the tower section transfer device may also include a diagonal brace 150, with both ends of the diagonal brace 150 connected to the crossbeam support arm 132 and the support frame 131 respectively. This arrangement can make the crossbeam support arm 132 more rigid and better support a single tower section through the crossbeam support arm 132.

[0053] In one feasible implementation, the tower section transfer device further includes: multiple extension rods, with a connecting hole provided on the side of the crossbeam support arm 132 or the diagonal brace 150 facing the load-bearing base 110; one end of the extension rod is used to connect to the crossbeam support arm 132 through the connecting hole, and the other end is used to abut against the tower section to be transferred; wherein, the multiple extension rods are divided into multiple groups, and the length of the extension rods in different groups is different.

[0054] In this technical solution, the tower section transfer device may also include multiple extension rods. The extension rods may be threaded to the bottom of the crossbeam support arm 132 or the diagonal brace 150. By rotating the extension rods, the effective length of the extension rods within the crossbeam support arm 132 or the diagonal brace 150 can be adjusted. Based on this, when a single tower section is set on the crossbeam support arm 132, one end of the extension rod can abut against the single tower section. Based on this, the single tower section can be hung at multiple points, which can reduce the probability of the single tower section swaying during the transfer process.

[0055] In this technical solution, multiple extension rods are divided into multiple groups, and the extension rods in different groups have different lengths. This arrangement allows the extension rods to be adapted to single tower sections with different inner diameters.

[0056] like Figure 1 As shown, in one feasible embodiment, the load-bearing base 110 is a frame structure, and the transfer hole 111 is arranged along the length or width of the load-bearing base 110.

[0057] In this technical solution, the style of the load-bearing base 110 is further provided, and the transfer hole 111 is arranged along the length or width of the load-bearing base 110, so that the forklift forks can be inserted into the transfer hole 111.

[0058] In one feasible implementation, the tower tube section transfer device further includes: a counterweight rod connected to the support frame 131 and located on the side of the support frame 131 opposite to the crossbeam support arm 132; and a counterweight component slidably disposed on the counterweight rod.

[0059] In this technical solution, the tower section transfer device may further include: a counterweight rod and a counterweight component, with the counterweight component slidably mounted on the counterweight rod. Based on this, the weight of a single tower section can be balanced by the counterweight component, which can prevent the tower section transfer device from tipping over. By sliding the counterweight component, the center of gravity of the counterweight rod and the counterweight component can be adjusted, so that the tower section transfer device can be adapted to the transfer of single tower sections of different models.

[0060] In one feasible implementation, the tower tube section transfer device further includes: a limiting screw, and a counterweight rod is provided with multiple threaded holes. The limiting screw is used to screw into the threaded holes to limit the counterweight.

[0061] In this technical solution, the tower tube section transfer device may also include a limit screw. After the counterweight is moved to the expected position, the limit screw can be used to limit the counterweight to stabilize the counterweight rod and the center of gravity of the counterweight.
