[0002] The wind turbine tower is the mast of wind power generation and the main supporting device of the wind turbine. It is mainly used to lift the nacelle and wind rotor to the required height, support the main engine and blades, and absorb the vibration of the turbine. The main functions of the wind turbine tower include supporting and fixing the wind turbine, absorbing and transmitting the vibration and stress generated by the wind turbine, and providing a platform for the installation, maintenance and repair of the wind turbine. In conjunction with other components such as lightning rods and sensors, it ensures the safe operation of the wind turbine. At present, during the processing of wind turbine towers, transportation equipment is needed to transport the wind turbine towers to facilitate the rapid circulation of the towers and improve the overall production capacity.

[0003] In the prior art, due to the large size and weight of wind turbine towers, wind turbine towers are generally transported using flatbed trucks. When a wind turbine tower needs to be transported, the staff first lifts the horizontally placed wind turbine tower to the top of the flatbed truck, and then uses wooden pads to limit the two sides of the wind turbine tower to prevent the wind turbine tower from detaching from the flatbed truck. Finally, the staff uses a pull rope to put on the wind turbine tower and fix the wind turbine tower on the top of the flatbed truck.

[0004] However, the existing technology still has major deficiencies, such as:

The tower body is automatically fixed by its own weight, which enhances the advantage of transportation stability.

[0028] 3. The rotating wheel, unwinding shaft and rope structure in the fixing assembly provide an additional fixing method for the wind turbine tower body.

[0040] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0041] See also Figures 1-10The present invention provides a technical solution: a wind turbine tower conveying device, comprising a wind turbine tower body 1, with conveying mechanisms 2 installed at the bottoms of both ends of the wind turbine tower body 1, for conveying and transporting conveying mechanisms 2 of different models;

[0042] The conveying mechanism 2 includes two support platforms 21 provided at the bottom of both ends of the wind turbine tower body 1, and the bottom of the two support platforms 21 are both equipped with moving wheels 22 for movement;

[0043] A placement buffer assembly 23 is installed on one side of the top of each of the two support platforms 21 to provide buffering when the wind turbine tower body 1 is placed;

[0044] A limiting assembly 24 is installed on the other side of the top of the two support platforms 21 to support the expansion of the wind turbine tower body 1;

[0045] A fixing assembly 25 is installed on the top of the two support platforms 21 and on one side of the placement buffer assembly 23, and the fixing assembly 25 is connected to the placement buffer assembly 23 to clamp and fix the wind turbine tower body 1 using its own weight.

[0046] Reference Figure 3 as well as Figure 5 As shown, the placement buffer assembly 23 includes two support seats 231 fixedly mounted on one side of the top of the two support platforms 21, and a support plate 232 is provided on the top of the two support seats 231. Both sides of the top of the support seat 231 are provided with a mounting cavity 233, and an air bag 234 is installed inside the mounting cavity 233. Rectangular blocks 235 are fixedly mounted on both sides of the bottom of the support plate 232, and the bottom of the rectangular block 235 passes through the mounting cavity 233 and is slidably connected to the mounting cavity 233.

[0047] A plurality of buffers 236 are installed through the top of the support base 231, and the telescopic ends of the buffers 236 are fixedly connected to the bottom of the support plate 232;

[0048] In this embodiment, when the wind turbine tower body 1 is placed on the support plate 232, its weight causes the support plate 232 to drop, the rectangular block 235 slides in the installation cavity 233 and squeezes the airbag 234, and at the same time the buffer 236 is compressed. The airbag 234 and the buffer 236 jointly play a buffering role, reducing the impact force generated when the wind turbine tower body 1 is placed.

[0049] Reference Figure 2 、 Figure 5 as well as Figure 6As shown, the fixing assembly 25 includes two second mounting shells 251 fixedly mounted on the tops of the two support platforms 21, and the second mounting shells 251 are mounted on the side where the buffer assembly 23 is placed. Bar holes 252 are opened on both sides of the top of the second mounting shells 251, and clamping plates 253 are slidably mounted on both sides of the interior of the second mounting shells 251. The top ends of the two clamping plates 253 pass through the bar holes 252 and extend to the top of the second mounting shells 251. The clamping plates 253 are slidably connected to the second mounting shells 251, and a clamping seat 254 is fixedly mounted on the adjacent side of the two clamping plates 253.

[0050] A piston cylinder 255 is installed on both sides of the second mounting housing 251. A piston plate 256 is slidably installed inside the piston cylinder 255. A piston rod 257 is fixedly installed on one side of the piston plate 256. One end of the piston rod 257 passes through the piston cylinder 255 and is fixedly connected to one side of the clamping plate 253. A return spring 258 is fixedly installed on the other side of the piston plate 256.

[0051] In this embodiment, when the wind turbine tower body 1 is placed on the support plate 232, the airbag 234 in the buffer assembly 23 is squeezed, and the gas in the airbag 234 enters the piston cylinder 255 through the air pipe 259, pushing the piston plate 256 to move. The piston plate 256 drives the clamping plate 253 to slide in the strip hole 252 through the piston rod 257, so that the clamping seat 254 is close to the wind turbine tower body 1, and the weight of the wind turbine tower body 1 itself is used to clamp and fix it. When the wind turbine tower body 1 is removed, the reset spring 258 resets the piston plate 256 and the clamping plate 253 returns to its initial position. The present invention uses the weight of the wind turbine tower body 1 itself to achieve automatic clamping and fixation, without the need for additional power equipment, with a simple structure and easy operation.

[0052] Reference Figure 5 As shown, air pipes 259 are installed through both ends of the support base 231, and the end of the air pipe 259 located inside the support base 231 is connected to the air bag 234, and the end of the air pipe 259 away from the support base 231 is connected to the end of the piston cylinder 255 located outside the second mounting shell 251;

[0053] In this embodiment, the air pipe 259 serves as a channel connecting the airbag 234 and the piston cylinder 255. When the airbag 234 in the buffer assembly 23 is squeezed, the gas in the airbag 234 enters the piston cylinder 255 through the air pipe 259, thereby linking the working processes of the buffer assembly 23 and the fixing assembly 25, and realizing the function of fixing by utilizing the weight of the wind turbine tower body 1.

[0054] Reference Figure 7 、 Figure 8 as well as Figure 9As shown, the tops of the two clamping plates 253 are each provided with a mounting groove 2501, wherein a rotating wheel 2502 is mounted inside one of the mounting grooves 2501. Both ends of the rotating wheel 2502 pass through the second mounting housing 251 and extend to the outside of the clamping plates 253. A through-hole 2503 is formed on the surface of the rotating wheel 2502, and a crank 2504 is mounted on one end of the rotating wheel 2502 located outside the clamping plates 253.

[0055] An unwinding shaft 2505 is installed through the interior of the other mounting groove 2501. Fixed housings 2506 are fixedly installed on both sides of the surface of the unwinding shaft 2505 and located inside the mounting groove 2501. Mounting shafts 2507 are installed through adjacent sides of the two fixed housings 2506. A coil spring 2508 is installed on the surface of the mounting shaft 2507 located inside the fixed housing 2506. A rope 2509 is provided on the surface of the mounting shaft 2507.

[0056] In this embodiment, turning crank 2504 rotates rotating wheel 2502, pulling rope 2509 from unwinding shaft 2505 and passing it through hole 2503 in rotating wheel 2502. The rope then winds around wind turbine tower body 1 and passes through hole 2503 again to secure it. As rope 2509 is pulled, coil spring 2508 on unwinding shaft 2505 is stretched. To release the unwinding shaft 2505, the elastic force of coil spring 2508 causes unwinding shaft 2505 to rotate, retracting rope 2509 and further securing wind turbine tower body 1. This enhances the securing effect and improves the stability of wind turbine tower body 1 during transportation.

[0057] Reference Figure 7 as well as Figure 10 As shown, an opening wheel 2510 is fixedly mounted on one end of the rotating wheel 2502 located outside the clamping plate 253, a mounting plate 2511 is fixedly mounted on the top of one side of the clamping plate 253, and a vertical rod 2512 is installed through the surface of the mounting plate 2511, and a rectangular plate 2513 is fixedly mounted on the top of the vertical rod 2512, and a limiting block 2514 is installed on the top of the rectangular plate 2513, and the limiting block 2514 is plugged into the opening on the surface of the opening wheel 2510, a pulling plate 2516 is fixedly mounted on the bottom end of the vertical rod 2512, and a support spring 2515 is fixedly mounted between the rectangular plate 2513 and the mounting plate 2511;

[0058] In this embodiment, when the rotating wheel 2502 rotates to the appropriate position, the elastic force of the support spring 2515 causes the limit block 2514 to insert into the opening on the surface of the opening wheel 2510, restricting the rotation of the rotating wheel 2502 and thereby fixing the length and tension of the rope 2509. When the rope 2509 needs to be adjusted, the pull plate 2516 is pulled downward to disengage the limit block 2514 from the opening of the opening wheel 2510, allowing the rotating wheel 2502 to rotate freely. This ensures that the rope 2509 is effectively bound to the wind turbine tower body 1, further improving the reliability of the fixation.

[0059] Reference Figure 2 、 Figure 3 as well as Figure 4 As shown, the limiting assembly 24 includes two slides 241 slidably mounted on the tops of the two support platforms 21, and a first mounting shell 242 is fixedly mounted on the tops of the slides 241, a screw 243 is installed through the interior of the first mounting shell 242, and a fixing plate 244 is sleeved on one side of the screw 243 located on the outer surface of the first mounting shell 242, and the fixing plate 244 is fixedly connected to one side of the first mounting shell 242, a threaded sleeve 245 is threadedly connected to the surface of the screw 243 located on the outer side of the first mounting shell 242, and expansion plates 246 are provided around the surfaces of the threaded sleeve 245 and the fixing plate 244, and a first connecting rod 247 is hinged between the threaded sleeve 245 and the expansion plate 246, and a second connecting rod 248 is hinged between the expansion plate 246 and the fixing plate 244;

[0060] A servo motor 249 is mounted on the top of one side of the first mounting housing 242. The output end of the servo motor 249 passes through the first mounting housing 242 and extends into the interior of the first mounting housing 242. A driving pulley 2401 is fixedly mounted on the output end of the servo motor 249. A driven pulley 2402 is mounted on the surface of the screw rod 243 located inside the first mounting housing 242. A transmission belt 2403 is wound around the surface of the driven pulley 2402. The driven pulley 2402 is connected to the driving pulley 2401 via the transmission belt 2403.

[0061] In this embodiment, servo motor 249 is activated, which drives driving pulley 2401 to rotate. Driving pulley 2401, via transmission belt 2403, drives driven pulley 2402 to rotate. Driven pulley 2402 then drives screw 243 to rotate. As screw 243 rotates, threaded sleeve 245 moves on screw 243, and through the transmission of first connecting rod 247 and second connecting rod 248, expansion plate 246 expands outward or contracts inward, thereby providing expansion support for wind turbine tower body 1. This further enables expansion support for wind turbine tower bodies 1 of different models, improving the versatility of the device.

[0062] Reference Figure 2 as well as Figure 3 As shown, hydraulic rods 2404 are installed on both sides of the surface of the support seat 231, and the telescopic ends of the two hydraulic rods 2404 are fixedly connected to one side of the slide 241. Slide rails 2405 are fixedly installed on both sides of the top of the support platform 21, and slide grooves 2406 are opened on both sides of the bottom of the slide 241. The slide 241 is slidably connected to the slide rails 2405 through the slide grooves 2406.

[0063] In this embodiment, the extension and retraction of the hydraulic rod 2404 drives the slide 241 to slide on the slide rail 2405 , thereby adjusting the position of the limiting assembly 24 so that it can accurately support the wind turbine tower body 1 .

[0064] Reference Figure 2 、 Figure 3 as well as Figure 4 As shown, there are six expansion plates 246 , and the six expansion plates 246 are equidistantly arranged on the surface of the threaded sleeve 245 and the fixed plate 244 , and a non-slip rubber pad is provided on the side of the expansion plate 246 away from the threaded sleeve 245 ;

[0065] In this embodiment, when the expansion plate 246 of the limiting assembly 24 expands outward, the six equidistantly arranged expansion plates 246 can evenly contact the inner wall of the wind turbine tower body 1, and the anti-slip rubber pad increases the friction between the expansion plate 246 and the wind turbine tower body 1, ensuring stable support for the wind turbine tower body 1 during transportation.

[0066] Reference Figure 1 As shown, a traction frame 3 is fixedly installed on one side of a support platform 21, and a traction hook 4 is fixedly installed on the side of the traction frame 3 away from the support platform 21 for traction of the device;

[0067] In this embodiment, the provision of the traction frame 3 and the traction hook 4 enables the transporting equipment to be conveniently connected to the traction vehicle, thereby facilitating long-distance transport of the wind turbine tower body 1 and improving the transport efficiency of the equipment.

[0068] Working principle: When the wind turbine tower body 1 needs to be transported, it is first hoisted onto the support plate 232 of the conveying mechanism 2. The weight of the wind turbine tower body 1 causes the support plate 232 to descend, and the rectangular block 235 then descends and squeezes the airbag 234 in the installation cavity 233. The gas in the airbag 234 enters the piston cylinder 255 through the air pipe 259, pushing the piston plate 256. The piston plate 256 drives the piston rod 257 to move the clamping plate 253 toward the wind turbine tower body 1, and the clamping seat 254 clamps and fixes the wind turbine tower body 1.

[0069] At the same time, the hydraulic rod 2404 is started to push the slide 241 to slide on the slide rail 2405, so that the limit assembly 24 moves into the wind turbine tower body 1, and the servo motor 249 is turned on. The servo motor 249 drives the active pulley 2401 to rotate, and the driven pulley 2402 drives the screw 243 to rotate through the transmission belt 2403. The threaded sleeve 245 on the screw 243 moves, and the expansion plate 246 is expanded through the first connecting rod 247 and the second connecting rod 248 to support the inside of the wind turbine tower body 1;

[0070] If further fixation is required, the crank 2504 can be shaken to rotate the rotating wheel 2502, the rope 2509 on the unwinding shaft 2505 can be wrapped around the rotating wheel 2502, and the opening wheel 2510 can be limited by the limiting block 2514 to prevent reversal, and finally the traction vehicle can be connected through the traction frame 3 and the traction hook 4 for transportation.

[0071] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
