Description

Technical Field

[0001] The utility model relates to the technical field of tower transportation, in particular to a multi-layer tower vertical transportation device. Background Art

[0002] Amid the rapid growth of the wind power industry, wind turbine towers, as crucial supporting structures for wind turbines, are crucial for the smooth operation of the entire project. However, traditional wind turbine tower transportation often involves horizontal placement, with the tower placed flat on a transport vehicle or ship. While this method simplifies loading and unloading processes to a certain extent, it presents numerous operational challenges.

[0003] Specifically, the precisely machined bolt holes on the tower are important interfaces for connecting the various sections of the tower and fixing it to the foundation. During the horizontal transportation process, the uneven distribution of the tower's own gravity, coupled with the bumps and vibrations during transportation and the influence of possible bad weather (such as strong winds and huge waves), can easily lead to stress concentration in the material around the bolt holes, which in turn causes deformation or damage. The deformation of the bolt holes not only directly affects the assembly accuracy of the tower, but also makes the installation of bolts during the hoisting process of the wind turbine extremely difficult, and even impossible to insert smoothly, seriously delaying the construction progress and increasing project costs. Moreover, horizontal transportation cannot stack multiple layers of towers, resulting in a large amount of space occupied by the transportation vehicle and low loading and unloading efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide a multi-layer tower vertical transportation device, aiming to solve the problems of insufficient stability, large space occupation and low loading and unloading efficiency encountered during the transportation of multi-layer towers.

[0005] To achieve this purpose, the present invention adopts the following technical solutions:

[0007] The lower surface of the base plate is mounted on an external transport vehicle, and the upper surface of the base plate is vertically mounted with the jacket. The jacket is in the shape of a hollow cavity, and a placement cavity is formed inside the jacket. The placement cavity is used to vertically stack at least two towers, and a spacer is installed between adjacent towers to limit the position.

[0008] The guide assembly is detachably mounted above the tower, and a guide groove is provided on the inner wall of the jacket in the vertical direction, and the guide groove is used to provide guidance for the guide assembly;

[0009] At least two lifting ears are protruding from the guide assembly, and the lifting ears are used for lifting by external lifting tools;

[0010] The guide assembly is provided with a tower locking hole, and the sleeve is provided with a sleeve locking hole. The tower locking hole and the sleeve locking hole correspond one to one. The tower is fixedly connected to the sleeve by a first fastener that passes through the sleeve locking hole and the tower locking hole in sequence.

[0011] Preferably, the guide assembly includes a guide connecting plate;

[0012] The guide connecting plate is detachably mounted above the tower, a guide wheel seat is mounted on the outer periphery of the guide connecting plate, a guide wheel is rotatably mounted in the guide wheel seat, and an outer wheel surface of the guide wheel is used to abut against the guide groove.

[0013] Preferably, a tower connecting seat is protruding from the outer periphery of the tower, and a tower connecting hole is formed through the tower connecting seat;

[0014] A guide connection seat is protruded from the outer periphery of the guide connection plate, a guide connection hole is formed through the guide connection seat, and the guide wheel seat is mounted on the guide connection seat;

This not only effectively reduces space occupancy and improves the utilization rate of transportation tools, but also significantly improves transportation efficiency and reduces the number of transports and costs.

Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0034] A multi-layer tower vertical transportation device includes a base plate 1, a jacket 2 and a guide assembly 3;

[0035] The lower surface of the base plate 1 is mounted on an external transport vehicle, and the upper surface of the base plate 1 is vertically mounted with the jacket 2. The jacket 2 is hollow, and a placement cavity is formed inside the jacket 2. The placement cavity is used to vertically stack at least two towers 100. A spacer 4 is installed between adjacent towers 100 to limit the position.

[0036] The guide assembly 3 is detachably mounted above the tower 100 , and a guide groove 21 is formed on the inner wall of the jacket 2 in the vertical direction. The guide groove 21 is used to provide guidance for the guide assembly 3 ;

[0037] At least two lifting ears 5 are protruding from the guide assembly 3, and the lifting ears 5 are used for lifting by external lifting tools;

[0038] The guide assembly 3 is provided with a tower locking hole 30, and the sleeve 2 is provided with a sleeve locking hole 20. The tower locking hole 30 and the sleeve locking hole 20 correspond one to one. The tower 100 is fixedly connected to the sleeve 2 by a first fastener 6 that passes through the sleeve locking hole 20 and the tower locking hole 30 in sequence.

[0039] like Figure 1-8 As shown, the working principle of the multi-layer tower vertical transportation device mainly relies on its structural design and the synergy between various components to achieve safe, stable and efficient vertical transportation of the tower 100. The specific working principle is as follows:

[0040] First, the base plate 1 is securely mounted on an external transport vehicle, such as a ship or truck, to serve as the foundation for the entire transport system. Next, the jacket 2 is vertically installed on the upper surface of the base plate 1, forming a hollow chamber within it. The towers 100 are then hoisted using external lifting tools via the lifting lugs 5 and stacked vertically within the chamber. Spacers 4 maintain appropriate spacing between adjacent towers 100 to prevent collision and damage during transport.

[0041] Next, a guide assembly 3 is installed at the top of the tower 100, and the guide assembly 3 matches the guide groove 21 provided vertically on the inner wall of the jacket 2. The guide groove 21 not only provides precise guidance for the guide assembly 3, but also ensures that the tower 100 remains upright during transportation, preventing tilting or shaking.

[0042] To further ensure the stability of the tower 100 during transportation, tower locking holes 30 are defined in the guide assembly 3, while corresponding sheath locking holes 20 are defined in the sheath 2. First fasteners 6, such as bolts and nuts, are threaded through these locking holes, creating a secure connection between the tower 100 and the sheath 2. This connection not only enhances the overall structural stability but also facilitates quick disassembly upon arrival.

[0043] Finally, after the tower 100 has been transported to its destination, the lifting rope of the hoisting tool is connected to the lifting lug 5 of the tower 100. The first fasteners 6 in the sheath locking holes 20 and the tower locking holes are then removed. The tower 100 is then hoisted out and allowed to rest. Because the guide assembly 3 is designed to be detachable, it can be easily removed, greatly improving convenience. The guide assembly 3 is then separated from the tower 100, and the tower 100 is then hoisted. This prevents deformation of the bolt holes 200 in the tower 100.

[0044] In summary, the present multi-layer tower vertical transport device transports the tower 100 by stacking multiple layers. Compared with traditional single-piece transport, the multi-layer stacking design allows more towers 100 to be transported within the same transport space, which not only effectively reduces the space occupancy rate and improves the utilization rate of the transport tool, but also significantly improves the transport efficiency and reduces the number of transports and costs. More importantly, the coordination of the guide assembly 3 with the guide groove 21 and the use of the first fastener 6 ensures the stability and safety of the tower 100 during transportation, reducing the risk of damage caused by shaking or tilting. At the same time, the design of the guide assembly 3 also makes the installation, positioning and fixing of the tower 100 simple and quick, reducing the difficulty of operation and labor costs.

[0045] It should be noted that the multi-layer tower vertical transportation device is suitable for transporting towers 100 of different specifications and sizes. Different needs can be met by simply adjusting the partition plate 4 and the first fastener 6, and has high flexibility and adaptability.

[0046] To further illustrate, the guide assembly 3 includes a guide connecting plate 31;

[0047] The guide connecting plate 31 is detachably mounted above the tower 100 . A guide wheel seat 32 is mounted on the outer periphery of the guide connecting plate 31 . A guide wheel 33 is rotatably mounted in the guide wheel seat 32 . The outer wheel surface of the guide wheel 33 is used to abut against the guide groove 21 .

[0048] like Figure 2-7 As shown, first, the guide connecting plate 31 is designed to be detachable, which is convenient for installation above the tower 100. Moreover, this detachable design enables the guide assembly 3 to flexibly adapt to towers 100 of different specifications and sizes, thereby improving the versatility and flexibility of the device.

[0049] Secondly, a guide wheel seat 32 is mounted on the outer periphery of the guide connecting plate 31, and a guide wheel 33 is rotatably mounted inside the guide wheel seat 32. The guide wheel 33 is a key component. Its outer wheel surface is in close contact with the guide groove 21 on the inner wall of the jacket 2, and it can abut and slide vertically along the trajectory of the guide groove 21, providing a stable guide for the installation and removal of the tower 100.

[0050] Finally, during transportation, as the transport vehicle moves, the tower 100 and the guide assembly 3 above it also move. At this time, the guide groove 21 can limit the lateral movement of the guide wheel 33, ensuring the vertical state of the tower 100 during transportation and preventing tilting or shaking.

[0051] To further illustrate, a tower connection seat 34 is protruded from the outer periphery of the tower 100, and a tower connection hole 340 is formed through the tower connection seat 34;

[0052] A guide connection seat 35 is protruded from the outer periphery of the guide connection plate 31 , and a guide connection hole 350 is formed through the guide connection seat 35 . The guide wheel seat 32 is mounted on the guide connection seat 35 .

[0053] The guide connecting plate 31 is fixedly connected to the tower 100 via a second fastener 7 that passes through the tower connecting hole 340 and the guide connecting hole 350 in sequence.

[0054] like Figure 2-7As shown, specifically, by sequentially passing the second fastener 7, such as a bolt and nut combination, through the tower connection hole 340 of the tower connection base 34 and the guide connection hole 350 of the guide connection base 35, the tower connection base 34 and the guide connection base 35 can be tightly connected together, thereby achieving a stable connection between the tower 100 and the guide connection plate 31. This connection method is not only simple and reliable, but also easy to install and disassemble.

[0055] To further explain, there is a distance between the guide connecting plate 31 and the tower 100 .

[0056] like Figure 7 As shown, during the transportation and installation of the tower 100, considering the importance of the precisely machined bolt holes 200 to the overall tower structure and their vulnerability to damage, the guide connecting plate 31 maintains a distance from the top of the tower 100. This effectively disperses the stress generated by the tower 100's own weight, jolts, vibrations, and adverse weather conditions during transportation. This design prevents stress from being directly concentrated in the bolt holes 200 area, reducing the risk of stress concentration, deformation, or damage to the material surrounding the bolt holes 200.

[0057] To further illustrate, the spacer plate 4 is provided with a limiting hole 40 , and the limiting hole 40 corresponds to the lifting lug 5 in a one-to-one manner.

[0058] like Figure 8 As shown, specifically, the design of the limiting holes 40 makes the installation process of the spacer plate 4 simple and quick, because the operator can intuitively find the corresponding hole position for installation.

[0059] To further explain, a buffer portion 41 is protruded from the bottom of the partition plate 4 , and the buffer portion 41 is elastic.

[0060] like Figure 8 As shown, because the spacer 4 is installed between adjacent towers 100, when the upper tower 100 is hoisted and placed by an external hoisting tool, the spacer 4 and the lower tower 100 are impacted by the gravity of the upper tower 100. This gravity is first transmitted to the buffer 41. Due to its elasticity, the buffer 41 can effectively absorb and disperse this impact energy, reducing the force directly transmitted to the lower tower 100, thereby providing protection.

[0061] To further explain, a plurality of supporting oblique rods 8 are provided on the outer periphery of the sheath 2 .

[0062] like Figure 1-2As shown, the supporting diagonal rods 8 are important structural components of the outer periphery of the sheath 2. Their main function is to provide additional support for the sheath 2 and the tower 100 inside. Through specific angles and layouts, external loads such as gravity and wind pressure borne by the sheath 2 can be effectively distributed to the transport vehicle or other fixed structures, thereby maintaining the stability of the entire transport device.

[0063] To further explain, a plurality of the sheaths 2 are installed side by side on the upper surface of the base plate 1 , and connecting ribs 9 are provided between adjacent sheaths 2 .

[0064] like Figure 1-2 As shown, by installing multiple jackets 2 side by side on the base plate 1 and connecting them with connecting ribs 9, a more stable and integrated structure is formed. Each jacket 2 not only bears its own weight and load and that of the tower 100 within it, but also shares the load with other jackets 2 through the connecting ribs 9, thereby enhancing the load-bearing capacity and stability of the entire structure.

[0065] Specifically, when a jacket 2 and its internal tower 100 are subjected to external loads such as wind or vibration, these loads first act on the jacket 2 and are then rapidly dispersed to adjacent jackets 2 and baseplates 1 via the connecting ribs 9. This load dispersion mechanism helps reduce stress concentration in a single jacket 2, thereby improving its service life and safety.

[0066] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to devise other specific embodiments of the present invention without inventive effort, and such equivalent variations or substitutions are encompassed within the scope of the claims of this application.
