Description

Technical Field

[0001] The present disclosure belongs to the technical field of tower barrel hoisting, and specifically relates to a tower barrel hoisting auxiliary device and a working method. Background Art

[0002] The statements herein only provide background art related to the present disclosure and do not necessarily constitute prior art.

[0003] With the continuous increase in the single-unit capacity of wind turbines, the weight of the wind turbines and the length of the blades are constantly increasing, which leads to a corresponding increase in the load acting on the tower barrel. Therefore, in order for the tower barrel to have higher strength, better stiffness, and greater height, corresponding adjustments and increases need to be made in terms of diameter, length, and wall thickness to ensure that it can withstand greater loads and maintain the structural stability.

[0004] Currently, during the hoisting process of the tower barrel, it is often connected through a lifting ring and the bolt holes on the flange. This results in the stress-bearing part of the lifting ring being on both sides of the lifting ring rather than on the connecting rod of the lifting ring. When the lifting ring is stressed on the side, the lifting ring is prone to fracture problems. Moreover, when using the lifting ring for hoisting, the lifting ring will cause wear on the surface anti-corrosion layer of the tower barrel flange part during the hoisting process, and the center of gravity control is not accurate, there is a risk of inclination during installation and positioning, and the verticality deviation is large, affecting the overall stability of the tower barrel. Summary of the Invention

[0005] The purpose of the present disclosure is to provide a tower barrel hoisting auxiliary device and a working method, which can solve at least one of the above technical problems.

[0006] To achieve the above purpose, one or more embodiments of the present disclosure provide a tower barrel hoisting auxiliary device, including at least two groups of hoisting devices. The hoisting device includes a hoisting plate, a bearing plate arranged perpendicular to the hoisting plate, and a first connecting piece connecting the tower barrel. A rib plate is arranged at the connection between the bearing plate and the hoisting plate. The first connecting piece is connected to the bearing plate. The bearing plate includes a first bearing plate and a second bearing plate, and the first bearing plate and the second bearing plate are arranged at intervals. The rib plate is arranged on the side of the first bearing plate and the second bearing plate facing away from each other.

[0007] Further, a first connection hole is arranged on the first bearing plate, and a second connection hole is arranged on the second bearing plate. The first connection hole and the second connection hole are coaxially arranged.

[0008] Further, the first connecting piece passes through the first connection hole and the second connection hole and is fixed by a nut.

[0009] Further, the rib plate includes a first rib plate, a second rib plate, a third rib plate, and a fourth rib plate. The first rib plate and the second rib plate are arranged on the same side, and the third rib plate and the fourth rib plate are arranged on the same side.

[0010] Furthermore, a through-hole connected to the lifting ring is provided on the lifting plate.

[0011] Furthermore, a second connecting member is provided on the through-hole. One end of the second connecting member is provided with a pin hole, and the other end is a bolt head.

[0012] Furthermore, the distance between the first load-bearing plate and the second load-bearing plate is greater than the thickness of the upper flange of the tower barrel.

[0013] Furthermore, a lifting rope for lifting is connected to the lifting ring.

[0014] Furthermore, the rib plate, the load-bearing plate, and the lifting plate, as well as between the load-bearing plate and the lifting plate, are all connected by welding.

[0015] A working method of the above-mentioned tower barrel lifting auxiliary device: First, connect the lifting device to the through-hole of the tower barrel flange, then connect the lifting ring to the lifting plate on the lifting device, and then connect it to the lifting ring through the lifting rope to perform the lifting operation of the tower barrel.

[0016] The beneficial effects of the above one or more technical solutions are as follows:

[0017] In the present disclosure, the first load-bearing plate and the second load-bearing plate are provided as the main load-bearing components for lifting the tower barrel, which can effectively avoid the risk of the side of the lifting ring being unable to withstand sufficient force and causing the lifting ring to break during traditional lifting operations.

[0018] In addition, after the lifting device is installed, the lifting direction of the lifting plate is always parallel to the axis of the tower barrel, which can ensure that the friction between the lifting device and the tower barrel is significantly reduced during the lifting process. This parallel arrangement enables the tower barrel to always maintain a vertically downward posture during the lifting process, thereby ensuring the positioning accuracy during the installation of the tower barrel. In this way, the problem of the tower barrel being skewed that may occur when using a traditional lifting ring for lifting is effectively avoided, thereby improving the safety and reliability of the entire lifting operation.

Detailed implementation manners

[0024] As introduced in the background art, in the existing method, the lifting ring is connected to the bolt holes on the flange. This causes the stress-bearing part of the lifting ring to be on both sides of the lifting ring rather than on the connecting rod of the lifting ring. When the lifting ring is stressed on the side, the lifting ring is prone to breakage problems. Moreover, when using the lifting ring for hoisting, the lifting ring will cause wear to the surface anti-corrosion layer of the tower barrel flange part during the hoisting process, and the center of gravity control is not accurate, there is a risk of inclination during installation and positioning, and the verticality deviation is large, affecting the overall stability of the tower barrel.

[0025] To solve the above technical problems, the present invention proposes an auxiliary device for hoisting a tower barrel. By using the device of the present invention, the problem of the lifting ring breaking directly in traditional hoisting operations can be avoided, and the tower barrel can always maintain a vertically downward posture during the hoisting process, thereby ensuring the positioning accuracy of the tower barrel during installation. In this way, the problem of the tower barrel skewing that may occur when using a traditional lifting ring for hoisting is effectively avoided, thereby improving the safety and reliability of the entire hoisting operation.

[0026] As Figures 1 - 3 shown, this embodiment provides an auxiliary device for hoisting a tower barrel, including at least two groups of hoisting devices. The hoisting device includes a hoisting plate 1, a load-bearing plate arranged vertically to the hoisting plate 1, and a first connecting member 9 connecting to the tower barrel 12. A rib plate is provided at the connection between the load-bearing plate and the hoisting plate 1; the first connecting member 9 is connected to the load-bearing plate, and the rib plate, the load-bearing plate and the hoisting plate 1, as well as between the load-bearing plate and the hoisting plate 1, are all connected by welding, ensuring the structural stability and load-bearing capacity. The hoisting device can select low-carbon killed steel or low-alloy steel with high mechanical strength and good impact toughness to meet the hoisting requirements. These materials can not only bear the weight of heavy objects, but also maintain the structural integrity when facing sudden impact forces, thereby ensuring the safety and reliability of the hoisting operation.

[0027] As Figure 2 and Figure 3As shown, the hoisting plate 1 is provided with a through hole connected to the lifting ring 11, which not only ensures a stable connection between the hoisting plate 1 and the lifting ring 11, but also a second connecting member 10 is connected to the through hole. A pin hole is provided at one end of the second connecting member 10, and a bolt head is designed at the other end. Such a design allows the connecting member to be flexibly used in conjunction with the lifting ring 11, and the pin hole can prevent the second connecting member 10 from slipping and separating from the lifting ring 11 during the hoisting process. In addition, in order to achieve the convenience of hoisting operations, a hoisting rope 14 for hoisting is also specially connected to the lifting ring 11 to ensure the safety and efficiency of the hoisting operation.

[0028] like Figure 1 As shown, the bearing plate includes a first bearing plate 2 and a second bearing plate 3, and the first bearing plate 2 and the second bearing plate 3 are spaced apart to ensure that there is enough space between them; the first bearing plate 2 is arranged on one side of the through hole set in the hanging plate 1, and the second bearing plate 3 is arranged away from the through hole of the hanging plate 1.

[0029] The first load-bearing plate 2 is provided with a first connecting hole 15 , and the second load-bearing plate 3 is provided with a second connecting hole 16 . The first connecting hole 15 and the second connecting hole 16 are coaxially arranged, and the first connecting member 9 passes through the first connecting hole 15 and the second connecting hole 16 and is fixed by a nut 8 .

[0030] Specifically, the spacing distance between the first bearing plate 2 and the second bearing plate 3 is greater than the thickness of the flange 13 on the tower 12, which can provide additional support and stability to ensure the strength and durability of the entire structure.

[0031] The first connection hole 15 and the second connection hole 16 are coaxially arranged to ensure that their positions in space correspond to each other. The connection between the first bearing plate 2, the second bearing plate 3 and the flange 13 is realized through the first connection member 9. The first connection member 9 can use a metal rod or bolt of appropriate length and diameter. A bolt head is arranged at one end of the first connection member 9, and a threaded section is arranged at the other end. After the first connection member 9 passes through the first connection hole 15 and the second connection hole 16, the nut is tightened on the end of the first connection member 9, thereby tightly connecting the two bearing plates and the flange 13 together, and the two bearing plates are firmly locked together, thereby ensuring the stability and bearing capacity of the entire structure.

[0032] The ribs are arranged on the opposite side of the first bearing plate 2 and the second bearing plate 3. Specifically, the ribs include the first rib 4, the second rib 5, the third rib 6 and the fourth rib 7. The stability and bearing capacity of the entire lifting device are improved by the ribs. Specifically, in order to achieve the best support effect, the first rib 4 and the second rib 5 are arranged on the same side, and the third rib 6 and the fourth rib 7 are arranged on the same side, so as to ensure that the bearing plate can be evenly and effectively supported when subjected to force.

[0033] Working method of the above-mentioned tower barrel hoisting auxiliary device of the present application:

[0034] As Figure 3 shown, first, install the hoisting device on both sides of the flange 13 of the tower barrel 12 through the first connecting piece 9. At this time, the hoisting plate 1 of the hoisting device is arranged parallel to the central axis of the tower barrel 12, and ensure the firm connection between the hoisting device and the through holes on the flange 13 through the first connecting piece 9. Then connect the lifting ring 11 with the hoisting plate 1 on the hoisting device through the second connecting piece 10 to ensure the reliability of the connection; subsequently, connect with the lifting ring 11 through the hoisting rope 14 to form a stable hoisting system; finally, carry out the hoisting operation of the tower barrel 12.

[0035] Although the specific implementation manners of the present disclosure are described above in conjunction with the accompanying drawings, it is not a limitation on the protection scope of the present disclosure. Those skilled in the art should understand that based on the technical solutions of the present disclosure, various modifications or deformations that can be made by those skilled in the art without creative efforts are still within the protection scope of the present disclosure.
