Description

Technical Field

[0001] This utility model belongs to the field of wind power technology, specifically a segmented wind turbine tower transfer tool. Background Technology

[0002] Wind turbine towers are a crucial component of wind power generation equipment, primarily used to support and secure the wind turbine nacelle and blades. With the continuous growth of installed wind power capacity, the structural dimensions of towers are constantly increasing to improve power generation efficiency. Currently, commonly used wind turbine towers typically have a diameter of 4-5 meters and a length of 20-30 meters, resulting in enormous overall weight. Since tower production bases are usually located at considerable distances from wind farm installation sites, the safe and stable transportation of such large and heavy towers from the production workshop to the destination has become a key technical challenge. The current common practice is to use extra-long flatbed trucks for transport, placing the towers horizontally or vertically on the truck body and initially securing them with straps.

[0003] Utility model patent CN212921277U discloses a support and operation mechanism for a wind turbine tower, including a front end, a body, and wheels. The front end is located at the front of the body, and the wheels are installed at the lower part of the body to enable the mobility of the overall structure. The body is equipped with a locking device for limiting the tower's position. The locking device consists of a fixed frame, a locking bracket, a screw, and a movable frame. The fixed frame includes a base plate and side plates on both sides, with the base plate fixed to the top of the body. The locking bracket is symmetrically mounted on the fixed frame and consists of a connecting end and an arc-shaped clamping end. The arc-shaped clamping end clamps and fixes the tower's arc shape through a screw mechanism, thus providing a certain degree of limiting and support. However, the clamping device in this patent still relies on ropes or straps for simple tower fixation, failing to completely break away from traditional manual binding methods. This fixing method has many drawbacks in practical applications: for example, during vehicle turns or sudden braking, the tower is prone to swaying or slipping due to its high center of gravity and uneven force distribution; in addition, during lifting and unloading, the concentrated force on the straps can easily lead to structural impact, and in severe cases, it can even cause local damage to the surface of the tower or loss of control during lifting, posing significant safety hazards. There is an urgent need for a more stable, efficient, and automated tower transfer and support solution. Utility Model Content

Limiting components 4 are arranged on both sides of the upper part of the main transport vehicle body 1. Lifting components 5 are arranged around the upper perimeter of the main transport vehicle body 1. The main transport vehicle body 1 is a steel structure platform vehicle used to bear the overall weight of the wind turbine tower. The main support components 2 are fixedly installed on the main transport vehicle body 1 to support the placement components 3 below. The placement components 3 are used to place the wind turbine tower. The placement components 3 can be quickly replaced according to the tower diameter to adapt to the transfer needs of different tower models. The limiting components 4 are installed on both sides of the upper part of the main transport vehicle body 1. The lifting components 5 facilitate the overall lifting of the transport vehicle and can provide lateral limiting on both sides of the wind turbine tower, replacing the manual fixing method of straps and ropes. During transportation, even if the vehicle turns or brakes suddenly, it can effectively suppress the risk of lateral swaying and rolling of the tower.

[0027] In one embodiment, see Figure 1 and Figure 2 As shown, the main support assembly 2 includes a mounting support base 21, which is detachably connected to the main transport vehicle body 1. The mounting support base 21 is provided with a positioning hole 211, and a placement component 3 is engaged in the positioning hole 211. During installation, the placement component 3 can be engaged by the mounting support base 21. During disassembly, the placement component 3 can be removed from the mounting support base 21. The main support assembly 2 is used to support the placement component 3 below. The placement component 3 is detachably connected to the main support assembly 2 and is used to place the wind turbine tower.

[0028] In one embodiment, see Figure 1 and Figure 3As shown, the placement component 3 includes a placement base plate 31, on which a conical connecting plate 32 is provided. The conical connecting plate 32 is detachably connected to the positioning hole 211. Supporting pads 33 are detachably connected to the upper two sides of the placement base plate 31. The conical connecting plate 32 has a conical structure, and its lower end is inserted into the positioning hole 211 on the main support component 2. It is kept stable by gravity and friction. The supporting pads 33 are detachably connected to the base plate by bolts. Different sizes of supporting pads 33 are selected according to the curvature of the bottom of the wind turbine tower, which realizes rapid assembly in the transportation preparation stage, stable support during transportation, and convenient disassembly after unloading. It is suitable for the transportation needs of tower sections of different lengths and diameters.

[0029] In one embodiment, see Figure 1 and Figure 3 As shown, the mounting support 21 is also provided with a positioning pin 34 for limiting the position of the tapered connecting plate 32. The mounting support 21 is provided with a mounting hole, and the tapered connecting plate 32 is provided with a positioning pin 34 through hole corresponding to the mounting hole. The positioning pin 34 is inserted so that it passes through the tapered connecting plate 32 and is inserted into the mounting hole on the support to limit the position of the tapered connecting plate 32.

[0030] In one embodiment, see Figure 1 and Figure 2 As shown, the limiting component 4 includes a limiting frame 41, on which a limiting screw 42 is provided. The limiting screw 42 is rotatably connected to the limiting frame 41. A limiting plate 43 is provided on the side of the limiting screw 42 away from the limiting frame 41. Several telescopic rods 44 are also provided between the limiting plate 43 and the limiting frame 41. After the wind turbine tower is loaded, the operator rotates the limiting screw 42 to push the limiting plate 43 forward, so that the wind turbine tower is clamped on both sides of the limiting plate 43. After unloading, the operator releases the limiting screw 42, and the limiting plate 43 smoothly retracts under the guidance of the telescopic rods 44, thus completing the unlocking.

[0031] In one embodiment, see Figure 1 and Figure 2 As shown, the limiting plate 43 is provided with an anti-slip and wear-resistant rubber pad 45. The high friction of the anti-slip and wear-resistant rubber pad 45 can prevent the tower from slipping relative to each other when the limiting plate is clamped, thereby improving the overall transportation stability and safety.
