[0002] Wind turbine tower is the tower pole of wind power generation, which mainly plays a supporting role in wind turbine generator set and absorbs the vibration of the set. Common wind turbine tower heights are 100 meters, 120 meters, 140 meters, 160 meters, etc. The height is relatively large. If the wind turbine tower is formed in one piece, it will be very inconvenient to transport and install. Therefore, wind turbine tower is usually assembled by splicing multiple sections of tower tube segments.

[0003] In the prior art, wind turbine tower segments are usually transported by flatbed trucks. A positioning seat is installed on the flatbed truck, and an arc-shaped groove is set on the top of the truck. The tower segment is placed in the groove for positioning. The groove is shallow, and since wind turbine equipment is usually installed in sparsely populated places with inconvenient transportation and bumpy roads, the wind turbine tower segment is prone to tilt or fall if it is positioned only by the positioning seat. Therefore, it is necessary to use wire ropes to tie and fix it before transportation. Since the diameter of the wind turbine tower segment is large, the staff needs to vigorously swing the wire rope to the other side, which is very laborious and often fails to succeed at one time.

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] Embodiment 1, in combination with the attached Figure 1 .

[0026] A wind turbine tower segment transportation and fixing structure comprises a positioning base 1 installed on a transport flatbed truck, wherein an arc-shaped groove 2 is provided on the top of the positioning base 1, and the wind turbine tower segment is placed in the arc-shaped groove 2, and further comprises two arc-shaped wings 3, wherein the two arc-shaped wings 3 are respectively arranged on both sides of the positioning base 1, and the bottom ends are hinged to the positioning base 1, and a driving mechanism is provided on the positioning base 1, which can drive the two arc-shaped wings 3 to open and close; the arc-shaped wings 3 are a two-section structure, comprising a first arc-shaped wing 4 and a second arc-shaped wing 5, and the ends of the two arc-shaped wings are elastically hinged to each other, and a self-locking mechanism 6 is provided at the hinged position of the two arc-shaped wings, which is used to clamp and fix the first arc-shaped wing 4 and the second arc-shaped wing 5 to the wind turbine tower segment.

[0027] Through the above structure, the two arc wings 3 can be opened outwards to facilitate the placement of wind turbine tower segments. After placing them in the arc groove 2 for preliminary positioning, the two arc wings 3 are moved toward the middle by the driving mechanism to clamp and fix the wind turbine tower segments. The first arc wing 4 and the second arc wing 5 are locked at an angle by the self-locking mechanism 6, thereby preventing the second arc wing 5 from being squeezed and rotated when passing through a bumpy road section.

[0028] Embodiment 2, combined with the attached Figure 1 , 4 .

[0029] The driving mechanism includes a sliding rod 8, a supporting rod 7, and a sliding block 9. The supporting rod 7 is hinged on the outer side of the first arc-shaped wing 4. A sliding rod 8 is rotatably arranged in the positioning base 1. Both ends of the sliding rod 8 extend to the outer side of the positioning base 1. The surfaces of the sliding rod 8 located on both sides of the positioning base 1 are provided with threads, and the two sections of the threads are in opposite directions. A sliding block 9 is hinged on the bottom end of the supporting rod 7, and the sliding block 9 cooperates with the threads of the sliding rod 8.

[0030] Limiting rods 10 parallel to the supporting rods 7 are also provided on both sides of the positioning base 1 , and through holes are provided on the sliding block 9 , which is slidably connected with the limiting rods 10 through the through holes.

[0031] Support seats 11 are provided on both sides of the positioning base 1 for supporting the sliding rod 8 and the limiting rod 10 .

[0032] A worm gear transmission group 12 is provided on the support seat 11, and the worm wheel of the worm gear transmission group 12 is fixedly set on the sliding rod 8. One end of the worm of the worm gear transmission group 12 is provided with a crank 13. The worm gear transmission group 12 meets the self-locking condition of the worm gear transmission.

[0033] Through the above structure, the worm is driven to rotate by turning the crank 13, which drives the worm wheel to rotate, and then drives the slide rod 8 to rotate. Since it is threadedly matched with the slider 9, and the slider 9 is restricted by the support rod 7 and the limit rod 10, the slider 9 moves along the slide rod 8 and drives the limit rod 10 to rotate, thereby pushing the arc-shaped wing 3 to move closer to the middle or open to both sides.

[0034] It is worth noting that since the first arc wing 4 and the second arc wing 5 are elastically hinged, in the free state, the angle between the first arc wing 4 and the second arc wing 5 is close to 90°. When the arc wing 3 moves toward the middle, the top of the second arc wing 5 first contacts the side wall of the wind tower segment. As the arc wing 3 continues to move toward the middle, the angle between the first arc wing 4 and the second arc wing 5 gradually increases to fit the wind tower segment.

[0035] Embodiment 3, in combination with the attached Figure 2 , 4 .

[0036] A pressure roller 19 is provided at the top end of the second arc-shaped wing 5, and the outer surface of the pressure roller 19 contacts the outer side wall of the wind turbine tower segment.

[0037] Through the above structure, when the arc wing 3 moves toward the middle, the pressure roller 19 at the top of the second arc wing 5 contacts the wind tower segment. As the arc wing 3 continues to move toward the middle, the pressure roller 19 rotates, which can reduce friction and avoid wear on the surface of the wind tower segment.

[0038] Embodiment 4, in combination with the attached Figure 3 .

[0039] The self-locking mechanism 6 includes a ratchet 14 and a pawl 15. The ratchet 14 is fixed to one end of the hinge shaft between the first arc-shaped wing 4 and the second arc-shaped wing 5 (the hinge shaft is fixed to the second arc-shaped wing 5). The pawl 15 is rotatably arranged on the first arc-shaped wing 4 and cooperates with the ratchet 14 to limit its reverse rotation.

[0040] A polygonal telescopic groove 16 is provided on the side wall of the first arc-shaped wing 4, and a polygonal telescopic block 17 is provided inside. A spring 18 is provided in the polygonal telescopic groove 16, and its two ends are respectively fixedly connected to the polygonal telescopic block 17 and the end of the polygonal telescopic groove 16, and the pawl 15 is elastically hinged to the polygonal telescopic block 17.

[0041] Through the above structure, when the second arc-shaped wing 5 rotates relative to the first arc-shaped wing 4, the ratchet 14 rotates with the second arc-shaped wing 5. Since the pawl 15 is elastically hinged to the polygonal telescopic block 17, when the ratchet 14 rotates, the pawl 15 is pushed to rotate and then reset, and repeatedly rotates forward and backward until the second arc-shaped wing 5 stops rotating. When the second arc-shaped wing 5 encounters a bumpy road section and is hit by a wind turbine tower segment, the pawl 15 limits the reverse rotation of the ratchet 14, thereby preventing the wind turbine tower segment from rolling off.

[0042] When the wind turbine tower segment needs to be removed, the two arc-shaped wings 3 are first opened to both sides, and the pawl 15 is pressed into the polygonal telescopic groove 16 to separate it from the ratchet 14. Since the first arc-shaped wing 4 is elastically hinged to the second arc-shaped wing 5, the second arc-shaped wing 5 is reset after the pawl 15 and the ratchet 14 are separated.

[0043] It is worth noting that the elastic hinge structure in the first embodiment and the fourth embodiment includes a hinge hole, a hinge shaft, and a torsion spring. The torsion spring is sleeved on the hinge shaft, and its two ends are fixedly connected to the two hinged parts. The hinge shaft of the first arc wing 4 and the second arc wing 5 is fixed on the second arc wing 5, the hinge hole is provided on the first arc wing 4, and the two ends of the torsion spring are fixedly connected to the first arc wing 4 and the second arc wing 5; the hinge shaft of the pawl 15 and the polygonal telescopic block 17 is provided on the pawl 15, the hinge hole is provided on the outer side wall of the polygonal telescopic block 17, and the two ends of the torsion spring are fixedly connected to the pawl 15 and the outer side wall of the polygonal telescopic block 17.

[0044] When the utility model is implemented, the wind turbine tower tube segment is placed in the arc groove 2, and the crank 13 is rotated to drive the arc wing 3 to move closer to the middle. After the pressure roller 19 at the top of the second arc wing 5 contacts the wind turbine tower tube segment, as the arc wing 3 continues to move closer, the second arc wing 5 rotates relative to the first arc wing 4, and the first arc wing 4 also fits the wind turbine tower tube segment, increasing the contact surface with the wind turbine tower tube segment, thereby clamping it. In this process, the pressure roller 19 rotates to reduce friction and avoid wear on the outer wall of the wind turbine tower tube segment; when encountering a bumpy road section, the pawl 15 prevents the ratchet 14 from reversing, thereby limiting the reversal of the second arc wing 5, and the worm gear 14 is rotated. The rod transmission group 12 meets the self-locking condition, so it is self-locking after the handle 13 stops turning, and the worm gear cannot drive the worm to rotate, thereby preventing the slide rod 8 from rotating, ensuring that the wind tower segment is clamped to prevent it from rolling; when unloading is completed after transportation, the handle 13 is turned in the opposite direction to drive the arc-shaped wings 3 to open to both sides, take out the wind tower segment, and then press the pawl 15 to one side of the polygonal telescopic groove 16 to make the polygonal telescopic block 17 slide into the polygonal telescopic groove 16, and the pawl 15 disengages from the ratchet 14 to reset the second arc-shaped wing 5. After letting go, the spring 18 drives the polygonal telescopic block 17 to extend, so that the pawl 15 is reset, which is convenient for next use.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
