[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] Embodiment 1: Please refer to Figures 1 - 10As shown in the figure, the present invention provides a technical solution: a tooling device for transporting a wind turbine tower barrel with high stability and multi-angle limitation, including: a first clamping table 1, a fastening component 2, a second clamping table 3, and a wind turbine tower barrel section 4. The first clamping table 1 is used to limit both ends of the wind turbine tower barrel section 4, and includes a first tooling table 101 in a concave shape. A chute 102 is opened in the middle of the depression at the top of the first tooling table 101. Sliding grooves 103 are opened on both raised sides at the top of the first tooling table 101. A sliding table 104 is slidably installed between the inner surfaces of the sliding grooves 103. A connecting frame 109 is arranged on the top of the sliding table 104, and a limiting plate 111 is arranged on the top of the connecting frame 109. The second clamping table 3 is installed in the middle depression of the first tooling table 101 and is used to limit the side of the wind turbine tower barrel section 4, and includes a second tooling table 301. A sliding seat 302 is fixedly connected to the bottom of the second tooling table 301. Both sides of the sliding seat 302 are arranged in the inner chute 102 through a plurality of groups of upper and lower symmetric rollers. Inner grooves 303 are opened at positions near both sides of the top of the second tooling table 301. Side clamping blocks 309 are symmetrically arranged inside the inner grooves 303. The number of the fastening components 2 is set to two and are respectively installed on the surface of the limiting plate 111 for strengthening the wind turbine tower barrel section 4.

[0024] Universal wheels 108 are installed at positions near the four corners of the bottom of the first tooling table 101. A long shaft 105 is rotatably connected inside the first tooling table 101, and both ends of the long shaft 105 respectively extend to the front and rear surfaces of the first tooling table 101. A first motor 107 is fixedly installed on the front side of the first tooling table 101. The output end of the first motor 107 penetrates the outer surface of the first tooling table 101 and is fixedly connected to the end of the long shaft 105. Threads 106 are symmetrically arranged on the outer surface of the long shaft 105 near both ends, and the long shaft 105 threadedly penetrates the two sliding tables 104 through the threads 106 on the surface.

[0025] Limiting rods 305 are symmetrically and fixedly connected between the inner surfaces of both sides of the inner groove 303 near the lower part. A bidirectional lead screw 304 is rotatably connected between the inner surfaces of both sides of the inner groove 303 near the middle of the lower part, and both ends of the bidirectional lead screw 304 respectively extend to the outer surfaces of both sides of the second tooling table 301. Moving seats 307 are symmetrically arranged inside the inner groove 303 near the lower part.

[0026] The outer surface of the limiting rod 305 slidably penetrates the outer surface of the moving seat 307, and the outer surface of the bidirectional lead screw 304 threadedly penetrates the outer surface of the moving seat 307. Two second motors 306 are installed on the outer surface of one side of the second clamping table 3. The output ends of the two second motors 306 penetrate the outer surface of the second tooling table 301 and are respectively fixedly connected to the ends of the two bidirectional lead screws 304.

[0027] Rotating sleeves 315 are symmetrically arranged at a position near the middle of the top of the second tooling table 301. A steel shaft 314 extending outward is rotatably connected inside the rotating sleeve 315. Both ends of the steel shaft 314 are rotatably connected to a support frame 313, and the support frame 313 is fixedly connected to the top of the second tooling table 301. The wind power tower cylinder section 4 is placed between the tops of the two rotating sleeves 315. A V-shaped clamping opening 312 is formed on the outer surface of the side clamping block 309 close to the wind power tower cylinder section 4. The inner wall of the V-shaped clamping opening 312 abuts against the outer surface of the wind power tower cylinder section 4, the outer surface of the limiting plate 111 abuts against the end face of the wind power tower cylinder section 4, and the outer surface of the long shaft 105 penetrates through the outer surface of the second tooling table 301.

[0028] Steps of using the present invention: The device consists of a first clamping table 1 and a second clamping table 3 to form a transportation tooling device for transporting the wind power tower cylinder. When in use, the wind power tower cylinder section 4 is placed on the two rotating sleeves 315, and it only needs to ensure that both ends of the wind power tower cylinder section 4 extend to the outside of the side clamping blocks 309 on the front and back sides. At this time, the support frame 313 fixes the steel shaft 314 on the top of the second tooling table 301. While the steel shaft 314 supports the rotating sleeve 315, the rotating sleeve 315 can rotate. At this time, when the wind power tower cylinder section 4 rotates, rolling friction is formed, which is convenient to rotate the surface with protruding configurations of the wind power tower cylinder section 4 to the upper side. Then, start the two second motors 306. Since the moving seat 307 in the inner groove 303 is restricted by the limiting rod 305 and cannot rotate, when the second motor 306 drives the bidirectional lead screw 304 to rotate, it will drive the two side clamping blocks 309 to approach the wind power tower cylinder section 4 and complete clamping and limiting of its side. At the same time, under the action of the V-shaped clamping opening 312, four-point positioning of the wind power tower cylinder section 4 is formed, so that it cannot move along the X and Y axes on the top of the second tooling table 301. Subsequently, start the first motor 107 to drive the long shaft 105 to rotate. The long shaft 105 will drive the sliding tables 104 inside the two sliding grooves 103 to move synchronously towards the middle through the spiral threads 106 on the surface. During the process, the limiting plate 111 above the sliding table 104 moves along with it. When the wind power tower cylinder section 4 maintains a centered state on the top of the second tooling table 301, one of the synchronously approaching limiting plates 111 will first contact the end of the wind power tower cylinder section 4 and generate a squeezing force. At this time, the sliding seat 302 at the bottom of the second tooling table 301 will slide in the inner sliding groove 102 and adjust the position of the second tooling table 301. During the process, the wind power tower cylinder section 4 moves along with it. When the two limiting plates 111 simultaneously abut against both ends of the wind power tower cylinder section 4, it can be fixed at the centered position above the device, so that it cannot move along the Z axis, thereby achieving the purpose of stably restricting the wind power tower cylinder section 4 from multiple angles, and it is not necessary to manually assist in adjusting the wind power tower cylinder section 4 to the centered position, improving the operation convenience. After the fixation is completed, the universal wheels 108 at the bottom of the first tooling table 101 can drive the wind power tower cylinder section 4 to move on the ground, or the device can be placed on a transport vehicle for long-distance transportation.

[0029] Embodiment 2: As Figures 1 - 10 shown, the difference from the basis of the embodiment is that a second sliding column 308 is fixedly connected to the top of the moving seat 307, a second sliding groove 310 is opened at the bottom of the side clamping block 309, the second sliding column 308 is slidably inserted into the second sliding groove 310, first sliding grooves 112 are symmetrically opened at the top of the sliding table 104, first sliding columns 113 are symmetrically and fixedly connected to the bottom of the connecting frame 109, and the first sliding columns 113 are slidably inserted into the first sliding grooves 112.

[0030] A long groove 110 is horizontally opened on the outer surface of the connecting frame 109, a pick rod 311 is fixedly connected to the outer surface of the side clamping block 309 close to the connecting frame 109, the pick rod 311 passes through the long groove 110, a V-shaped valley 316 is formed at the junction of the inner walls of the V-shaped clamping opening 312, the top of the limiting plate 111 is semicircularly arranged, and the center of the limiting plate 111 and the V-shaped valley 316 are at the same height.

[0031] The usage steps of the present invention: Since the side clamping block 309 is connected to the moving seat 307 through the second sliding groove 310 and the second sliding column 308, and the connecting frame 109 is connected through the first sliding groove 112 and the first sliding column 113, both the side clamping block 309 and the connecting frame 109 can move up and down. When adjusting the two side clamping blocks 309 to approach and clamp the wind power tower cylinder section 4, when the upper inclined clamping surface of the V-shaped clamping opening 312 contacts the surface of the wind power tower cylinder section 4, the upper inclined clamping surface will move along the tangent direction of the wind power tower cylinder section 4, thereby forcing the height of the side clamping block 309 to gradually rise during the movement until the V-shaped valley 316 and the center of the end face of the wind power tower cylinder section 4 are at the same height. During this process, when the side clamping block 309 moves horizontally, the pick rod 311 on its surface will move horizontally in the long groove 110, and when the side clamping block 309 rises, the pick rod 311 will drive the connecting frame 109 to rise synchronously and play the role of adjusting the height of the limiting plate 111. And since the center of the V-shaped valley 316 and the center of the semicircular surface of the limiting plate 111 are at the same height, when the side clamping block 309 firmly clamps the wind power tower cylinder section 4, the center of the semicircular surface of the limiting plate 111 will coincide with the center of the end face of the wind power tower cylinder section 4. This design effectively fixes the wind power tower cylinder sections 4 with different diameters through the adaptively liftable side clamping block 309 and the limiting plate 111, so that it can be used for the wind power tower cylinder sections 4 with different diameters at different parts without additional operations.

[0032] Embodiment 3: As Figures 1 - 6As shown, the difference between the embodiment and the fastening assembly 2 is that the fastening assembly 2 includes a circular shell 201, which is fixedly mounted on the outer surface of the limiting plate 111 close to the wind tower barrel section 4, and a circular inner cavity 202 is opened inside the circular shell 201. A rotating shaft 203 is rotatably connected between the front and rear inner walls of the circular shell 201, and one end of the rotating shaft 203 rotates through the circular shell 201 and the outer surface of the limiting plate 111. An end of the rotating shaft 203 away from the circular shell 201 is fixedly connected to an inclined connecting rod 211, and a connecting shaft 212 is fixedly connected to the outer surface of the connecting rod 211 away from the rotating shaft 203. A hydraulic cylinder 213 is rotatably connected to the outer surface of the limiting plate 111. The end of the hydraulic cylinder 213 away from the connecting shaft 212 is rotatably connected to the outer surface of the limiting plate 111 through the shaft.

[0033] There are multiple wheel frames 208 evenly distributed in the circumferential direction of the inner cavity 202, and contact wheels 209 are rotatably connected between the inner walls of the multiple wheel frames 208. A connecting rod 206 is fixedly connected to the outer surface of the wheel frame 208. The end of the connecting rod 206 passes through the inner wall of the inner cavity 202 and extends outward. An end of the connecting rod 206 away from the wheel frame 208 is fixedly connected to a resistance block 207. The outer surface of the connecting rod 206 is located between the outer surface of the wheel frame 208 and the inner wall of the inner cavity 202, and a compressed spring 210 is sleeved.

[0034] The outer surface of the rotating shaft 203 is fixedly connected to a circular sleeve 204 at a position inside the inner cavity 202, and a plurality of half-moon blocks 205 are evenly distributed circumferentially on the outer surface of the circular sleeve 204. The number of the half-moon blocks 205 is consistent with the number of the wheel frames 208. The outer arc surface of the half-moon block 205 is in contact with the contact wheel 209, and a limiting block 214 is provided on the outer surface of the half-moon block 205 at a position away from the circular sleeve 204.

[0035] Steps of using the present invention: When the limiting plate 111 abuts against the end of the wind turbine tower barrel section 4, the circular shell 201 with a smaller diameter will enter the inner side of the wind turbine tower barrel section 4. At this time, the hydraulic cylinder 213 is started to push the connecting shaft 212, and the rear connecting rod 211 will drive the rotating shaft 203 and the circular sleeve 204 in the inner cavity 202 of the circular shell 201 to rotate. When the circular sleeve 204 rotates, the arc surface of the semi-circular block 205 will abut against the contact wheel 209 and push it outwards. At this time, the wheel frame 208 squeezes the spring 210 to contract and drives the abutting block 207 on the surface of the circular shell 201 to spread outwards through the connecting rod 206, and then plays a role in abutting against the inner wall of the wind turbine tower barrel section 4 from the inside, thereby improving the firmness of the wind turbine tower barrel section 4. Moreover, after the radially expanding abutting block 207 abuts tightly against the inner wall of the wind turbine tower barrel section 4, it can effectively reduce the axial load of the limiting plate 111, and at the same time disperse the burden of the two side clamping blocks 309, improving the stability when using this device to transport the wind turbine tower barrel section 4. Among them, when the hydraulic cylinder 213 expands and contracts, its telescopic end will rotate with the connecting shaft 212, and the other end will rotate with the limiting plate 111 through the shaft. And, by arranging a limiting block 214 on the surface of the semi-circular block 205, when the semi-circular block 205 rotates excessively, it will abut against the wheel frame 208, thus avoiding excessive rotation.

[0036] The effects achieved by the entire mechanism and its working principle are as follows: During use, place the wind turbine tower cylinder section 4 on the two rotating sleeves 315, and only ensure that both ends of the wind turbine tower cylinder section 4 extend to the outside of the front and rear side clamping blocks 309. At this time, the support frame 313 fixes the steel shaft 314 on the top of the second tooling table 301. While the steel shaft 314 supports the rotating sleeve 315, the rotating sleeve 315 can rotate. At this time, when the wind turbine tower cylinder section 4 rotates, rolling friction is formed, which is convenient for rotating the surface with protruding configurations of the wind turbine tower cylinder section 4 to the upper side. Then, start the two second motors 306. Since the moving seat 307 in the inner groove 303 is restricted by the limiting rod 305 and cannot rotate, when the second motor 306 drives the bidirectional lead screw 304 to rotate, it will drive the two side clamping blocks 309 to approach the wind turbine tower cylinder section 4 and complete clamping and limiting of its side. At the same time, under the action of the V-shaped clamping opening 312, four-point positioning of the wind turbine tower cylinder section 4 is formed, so that it cannot move along the X and Y axes on the top of the second tooling table 301. Subsequently, start the first motor 107 to drive the long shaft 105 to rotate. The long shaft 105 will drive the sliding tables 104 inside the two sliding grooves 103 to move closer to the middle synchronously through the surface spiral threads 106. During the process, the limiting plates 111 above the sliding tables 104 move along. When the wind turbine tower cylinder section 4 remains centered on the top of the second tooling table 301, one of the synchronously approaching limiting plates 111 will first contact the end of the wind turbine tower cylinder section 4 to generate a squeezing force. At this time, the sliding seat 302 at the bottom of the second tooling table 301 will slide in the inner sliding groove 102 and adjust the position of the second tooling table 301. During the process, the wind turbine tower cylinder section 4 moves along. When the two limiting plates 111 simultaneously press against both ends of the wind turbine tower cylinder section 4, it can be fixed at the centered position above this device, so that it cannot move along the Z axis, thereby achieving the purpose of stably restricting the wind turbine tower cylinder section 4 from multiple angles, and there is no need to manually assist in adjusting the wind turbine tower cylinder section 4 to the centered position, improving the operation convenience. After the fixation is completed, the universal wheels 108 at the bottom of the first tooling table 101 can drive the wind turbine tower cylinder section 4 to move on the ground, or this device can be placed on a transport vehicle for long-distance transportation; During use, since the side clamping block 309 is connected to the movable seat 307 through the second slide groove 310 and the second slide column 308, and the connecting frame 109 is connected to the first slide groove 112 and the first slide column 113, the side clamping block 309 and the connecting frame 109 can move up and down. When the side clamping blocks 309 on both sides are adjusted to approach and clamp the wind tower barrel section 4, as the upper inclined clamping surface of the V-shaped clamping opening 312 contacts the surface of the wind tower barrel section 4, the upper inclined clamping surface will move along the tangent direction of the wind tower barrel section 4, thereby forcing the side clamping block 309 to gradually rise in height during the movement process until the V-shaped valley 316 and the center of the end face of the wind tower barrel section 4 are at the same height. During this process, the side clamping block 309 moves horizontally. When the side clamp block 309 is raised, the lifting rod 311 on its surface will move laterally in the long groove 110, and when the side clamp block 309 rises, the lifting rod 311 will drive the connecting frame 109 to rise synchronously and achieve the effect of adjusting the height of the limiting plate 111, and because the centers of the semicircular surfaces of the V-shaped valley 316 and the limiting plate 111 are at the same height, when the side clamp block 309 firmly clamps the wind tower barrel section 4, the center of the semicircular surface of the limiting plate 111 will coincide with the center of the end face of the wind tower barrel section 4. This design achieves the effect of effectively fixing the wind tower barrel sections 4 of different diameters through the side clamp block 309 and the limiting plate 111 that can be self-adaptively raised and lowered, so that it can be used for wind tower barrel sections 4 of different diameters at different parts without additional operation; When the limit plate 111 is against the end of the wind tower barrel section 4, the circular shell 201 with a smaller diameter will enter the inner side of the wind tower barrel section 4. At this time, after the hydraulic cylinder 213 is started to push the connecting shaft 212, the connecting rod 211 will drive the rotating shaft 203 and the circular sleeve 204 in the inner cavity 202 of the circular shell 201 to rotate. When the circular sleeve 204 rotates, the arc surface of the half-moon block 205 will contact the contact wheel 209 and push it outward. At this time, the wheel frame 208 squeezes the spring 210 to contract and drive the contact block 207 on the surface of the circular shell 201 to diffuse outward through the connecting rod 206, and then play a role of resisting the inner wall of the wind tower barrel section 4 from the inside, thereby improving the firmness of the wind tower barrel section 4, and the radially expanded contact block 207 can also effectively reduce the axial load of the limit plate 111 after pressing against the inner wall of the wind tower barrel section 4, and at the same time disperse the burden of the side clamps 309 on both sides, thereby improving the stability when using this device to transport the wind tower barrel section 4.
