Description

Technical Field

[0001] This utility model relates to the technical field of wind tower transportation, and in particular to a wind tower transportation support fixture. Background Technology

[0002] The wind turbine tower, located between the wind turbine and the foundation ring, primarily supports the immense weight of the wind turbine, including components such as the rotor, generator, and nacelle, ensuring their stable erection on land or at sea and guaranteeing normal operation under various wind conditions. During wind turbine operation, various vibrations and swaying occur; the wind turbine tower effectively absorbs and buffers these vibrations, reducing their impact on the foundation and other components, and extending the turbine's service life.

[0003] The existing announcement number is CN222102192U, which discloses an anti-roll support structure for a wind tower transport vehicle. The structure includes a vehicle platform with a fixing structure on its top surface. A tower body is positioned above the platform. The fixing structure includes a mounting shell fixed to the top surface of the platform. A first bidirectional lead screw is rotatably mounted inside the mounting shell, and tensioning plates are fixed to the positive and negative threads of the first bidirectional lead screw. This invention, through the fixing structure, allows the operator to start a drive motor, which rotates the first bidirectional lead screw. The first bidirectional lead screw, through a first bevel gear and a second bevel gear, rotates a second bidirectional lead screw. This causes the two tensioning plates and two movable plates to simultaneously move closer to or further away from the center of the mounting shell. This allows the tensioning plates and movable plates to securely fasten the tower body according to the size of its inner wall, eliminating the need for additional internal devices for fixing. The design is convenient and easy to use.

[0004] While the first and second bevel gears can drive the second bidirectional lead screw to rotate, causing the two tensioning plates and two movable plates to simultaneously move closer to or further away from the center of the mounting shell, thus allowing the tensioning plates and movable plates to clamp and fix the tower body according to the size of the inner wall surface, the fixed positions of the tensioning plates and movable plates, coupled with the fact that wind turbine towers, as large and critical components, have extremely wide length specifications ranging from short segmented towers to ultra-long integrated towers, present challenges. When handling shorter tower segments, the tower needs to be moved closer to the mounting shell during hoisting to ensure that the tensioning plates and movable plates can effectively contact and clamp against the inner wall of the tower. However, the tower itself is heavy and has high inertia. Fine-tuning its position during hoisting requires coordination between the hoisting equipment and the fixed structure, increasing the operational difficulty and extending the time cost of the hoisting operation. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a wind tower transportation support fixture.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A wind tower transport support fixture includes a platform, on which a double-ended threaded rod is rotatably connected. The double-ended threaded rod is threadedly connected to two sets of plates, each set of plates having an inclined surface at one end. Two sets of connectors are fitted onto the platform. The platform has multiple sets of holes (first type). Each of the two sets of connectors has holes (second type) at one and the other end. Bolts are threadedly connected to the multiple sets of holes (second type). The bolts are threadedly connected to corresponding holes (first type). Each of the two sets of connectors has a groove, and threaded rods are rotatably connected to the two sets of grooves.

[0007] Preferably, both sets of threaded rods are threadedly connected to baffles, and the two sets of baffles are slidably connected to the corresponding grooves, with one end of each set of baffles being arc-shaped.

[0008] Preferably, each of the multiple sets of bolts has a knob connected to one end.

[0009] Preferably, the vehicle plate has multiple sets of sliding grooves, and each of the two sets of plates has two sets of sliders connected to one end, with the multiple sets of sliders slidably connected to the corresponding sliding grooves.

[0010] Preferably, a handwheel is connected to one end of both the double-ended threaded rod and the two sets of threaded rods.

[0011] Preferably, a rubber pad is connected to one end of each of the two sets of baffles.

[0012] Preferably, one end of each of the two sets of plates is connected to a rubber pad.

[0013] The beneficial effects of this utility model are as follows: 1. By coordinating the double-threaded rod, plates, and connectors, rotating the double-threaded rod moves the two sets of plates closer or further apart, thereby adjusting the plate spacing. This design can accommodate towers of different diameters to a certain extent, whether they are thinner segmented towers or thicker integrated towers. Stable support can be achieved by adjusting the plate spacing, meeting diverse diameter requirements to a certain extent. Multiple pre-set holes on the vehicle plate and holes on the connectors form a detachable connection structure via bolts, providing ample space for longitudinal position adjustment of the connectors. For short towers, the two sets of connectors can be moved closer to the center of the vehicle plate to ensure a tight fit between the connectors and the sides of the tower, forming reliable support. For long towers, the connectors can be distributed towards both ends of the vehicle plate, increasing the spacing between support points and improving the stable clamping capability for long towers. This design eliminates the need for repeated fine-tuning of the tower's position on the vehicle plate using lifting equipment; adaptation is achieved simply by adjusting the position of the connectors themselves, reducing operational complexity and improving the tooling's flexibility in adapting to towers of different lengths. 2. Through the cooperation of the threaded rod and baffle, rotating the threaded rod can move the baffle, adjusting its height to fit the inner wall of the tower with different thicknesses to a certain extent. The groove provides stable guidance for the baffle's movement, ensuring the smoothness of the adjustment process. The baffle end is designed with an arc shape, which can closely fit the contour of the inner wall of the tower, forming a coordinated internal and external clamping with the plate, reducing the swaying of the tower during transportation to a certain extent and enhancing the overall transportation safety.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Example 1, referring to Figures 1 to 5A wind tower transport support fixture includes a platform 1, on which a double-threaded rod 2 is rotatably connected. Rotating the double-threaded rod 2 adjusts the position of the plate body 3, adapting to different sizes of wind towers to a certain extent. The double-threaded rod 2 is threadedly connected to two sets of plate bodies 3, each with an inclined end, allowing for a closer fit to the curved contour of the wind tower's outer wall. This increases the contact area while dispersing pressure on the wind tower, preventing excessive local stress that could lead to wind tower deformation or fixture damage, and improving structural stability during transport. Two sets of connectors 4 are fitted onto the platform 1, for fitting against both sides of the wind tower. To a certain extent, the movement of the tower is restricted. Multiple sets of holes 5 are provided on the platform 1. Two sets of connecting parts 4 each have holes 6 at one and the other ends. Bolts 7 are threaded into these holes 6. Tightening the bolts 7 into the holes 5 fixes the connecting parts 4, thereby securing the tower. The bolts 7 are threaded into the corresponding holes 5. Both sets of connecting parts 4 have grooves 8, and threaded rods 9 are rotatably connected to the grooves 8. The multiple sets of holes 5 on the platform 1 and the holes 6 of the connecting parts 4, through the bolts 7, allow for adjustment of the longitudinal installation position of the connecting parts 4 on the platform 1. For short towers, the two sets of connecting parts 4 can be brought closer to the center of the platform 1 to ensure close support to both sides of the tower. For long towers, the connecting parts 4 can be fixed separately at both ends of the platform 1. This allows for stable clamping without relying on repeated fine-tuning of the tower position using lifting equipment, reducing operational difficulty and shortening operation time.

[0018] In this embodiment, both sets of threaded rods 9 are threadedly connected to baffles 10. Rotating the threaded rods 9 moves the baffles 10, and adjusting the height of the baffles 10 allows them to fit against the inner walls of towers of different thicknesses. The two sets of baffles 10 are slidably connected to corresponding grooves 8, and the grooves 8 guide the movement of the baffles 10. One end of both sets of baffles 10 is arc-shaped, which conforms to the contour of the inner wall of the tower to a certain extent. By adjusting the position of the baffles 10 to cooperate with the plate 3, the tower is clamped, which to a certain extent prevents the tower from shaking during transportation. One end of each set of bolts 7 is connected to a knob 11, which makes it easier to rotate the bolts 7. Multiple sets of sliding grooves 12 are provided on the plate 1. One end of each set of plate 3 is connected to two sets of sliders 13, and the multiple sets of sliders 13 are slidably connected to the corresponding sliding grooves 12. The sliding grooves 12 and sliders 13 cooperate to guide the movement of the plate 3. Each of the double-ended threaded rod 2 and the two sets of threaded rods 9 has a handwheel 16 connected to one end, which facilitates the rotation of the double-ended threaded rod 2 and the two sets of threaded rods 9. Each of the two sets of baffles 10 has a rubber pad 14 connected to one end, increasing the friction with the inner wall of the tower and improving clamping stability to some extent. Each of the two sets of plates 3 has a rubber pad 15 connected to one end, increasing the friction with the outer wall of the tower and improving placement stability to some extent.

[0019] The working principle of this embodiment is as follows: In use, the wind tower is hoisted onto the vehicle platform 1. According to the length specifications of the tower, the bolt 7 is turned by the knob 11 to unscrew the bolt 7 from the original hole 5 and hole 6. The longitudinal position of the two sets of connecting parts 4 on the vehicle platform 1 is adjusted, and then the bolt 7 is screwed into the corresponding hole 5 and hole 6 to complete the fixing of the connecting parts 4. The double-threaded rod 2 is rotated by the handwheel 16. Since the double-threaded rod 2 is threadedly connected to the two sets of plates 3, and the plates 3 slide with the slide groove 12 of the vehicle platform 1 through the slider 13, the rotation of the double-threaded rod 2 drives the two sets of plates 3 to move closer or further apart along the slide groove 12 until the inclined surface of the plates 3 with the rubber pad 15 is in contact with the outer wall of the tower, thus achieving the initial lateral clamping of the tower. By rotating the handwheel 16, the threaded rods 9 inside the grooves 8 of the two sets of connecting parts 4 are rotated. The rotation of the threaded rods 9 causes the baffle 10 to slide along the grooves 8 until the arc-shaped end of the baffle 10 with the rubber pad 14 is tightly fitted against the inner wall of the tower, further fixing the tower. During transportation, the plate 3 and the baffle 10 cooperate to form a stable clamp on the tower from both the inside and outside. The rubber pads 14 and 15 increase the friction, preventing the tower from shaking and ensuring the stability of the transportation process.

[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
