Description

Technical Field

[0001] This utility model relates to the field of wind turbine tower technology, specifically to an anti-deformation support device for wind turbine towers during transportation. Background Technology

[0002] Wind turbine towers are primarily used to support wind turbine generators, positioning the rotor, gearbox, generator, and other equipment to capture high-altitude wind energy. They bear the weight of the nacelle, blades, and other components, ensuring the stable operation of the entire wind turbine generator set.

[0003] The prior art discloses a deformation-resistant support structure for wind turbine towers, with announcement number CN221504366U. The structure includes a tower with both ends placed in support grooves at the center of the top of a support base. A rotating base is located at the bottom of the support base, and casters are positioned at the four corners of the rotating base. Fixing components for clamping and stabilizing both ends of the tower are located on both sides of the support base. These fixing components also include clamping mechanisms at both ends of a bidirectional screw. By providing the support base, support grooves, rotating base, and casters, the structure supports and places the tower, preventing it from being placed directly on the ground, which could cause deformation of the fixed flange at one end of the tower, affecting subsequent installation. Simultaneously, the support base is movable and rotatable, facilitating subsequent movement and hoisting of the tower, and improving the flexibility of the device.

[0004] The aforementioned clamping mechanism moves left and right via a bidirectional screw, which requires the entire device to be cut when the clamping mechanism is replaced, making the replacement of the clamping mechanism quite troublesome and requiring a lot of time to maintain the clamping mechanism.

The limiting plug slides on the surface of the plug-in frame, allowing the plug-in frame to be inserted into the position of the metal frame and the support base, thereby determining the position of the support base and facilitating the disassembly and replacement of the support base.

[0011] Preferably, there are four movable rollers, with two movable rollers forming a group. The two groups of movable rollers are distributed front to back, and two movable rollers on the same side are distributed vertically.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 The present invention provides the following technical solution:

[0025] A deformation-resistant support device for wind turbine towers during transportation includes a clamping device 1 and a bearing base 3. The top of the bearing base 3 is connected to the wind turbine tower 2, and the bearing base 3 is inserted into the middle position of the clamping device 1.

[0026] The clamping device 1 includes a metal frame 11, a plug-in frame 12, a clamp 13, an electric push rod 14, and a limiting block 15. The electric push rod 14 is fixedly connected to the top of the metal frame 11 and installed at the bottom of the support block 131. The electric push rod 14 is installed inside the metal frame 11. The support block 131 can determine the position of the electric push rod 14, which facilitates the disassembly and replacement of the electric push rod 14, increases the service life of the electric push rod 14, and protects the safety of the electric push rod 14. The limiting block 15 is threadedly connected to the inside of the electric push rod 14. The end of the plug rod is slidably connected to the surface of the insertion frame 12. The insertion block 15 is inserted into the middle position of the metal frame 11 and the bottom of the support base 3. The insertion block 15 slides on the surface of the insertion frame 12, allowing the insertion frame 12 to be inserted into the position of the metal frame 11 and the support base 3, thereby determining the position of the support base 3 and facilitating the disassembly and replacement of the support base 3. The clamp 13 is threaded to the front and rear ends of the metal frame 11, and the insertion frame 12 is threaded to the left and right sides of the metal frame 11.

[0027] The clamp 13 includes a support block 131, a metal arm 132, a movable roller 133, a helical spring 134, a metal slide rod 135, a connector 136, and a limiting cover plate 137. The limiting cover plate 137 is threaded to the upper and lower ends of the metal slide rod 135. The connector 136 is slidably connected to the surface of the metal slide rod 135. The metal slide rod 135 is located inside the helical spring 134. The helical spring 134 can adjust the vertical movement of the metal arm 132, allowing the metal arm 132 to adjust the position of the movable roller 133. This clamp can hold and fix wind turbine towers 2 of different specifications, facilitating the disassembly and replacement of the wind turbine towers 2. The helical spring 134 is fixedly connected to the inward side surface of the connector 136. The 36 threaded connection is located at the middle position of the metal arm 132. The movable roller 133 is installed at the inward end of the metal arm 132. There are four movable rollers 133. Two movable rollers 133 form a group. The two groups of movable rollers 133 are distributed front and back. Two movable rollers 133 on the same side are distributed vertically. The movable rollers 133 are rotatably connected to the surface of the wind turbine tower 2. The movable rollers 133 and the bearing base 3 can clamp and fix the wind turbine tower 2, which can prevent the wind turbine tower 2 from shaking. The metal arm 132 is rotatably connected to the top of the support block 131. The support block 131 is threadedly connected to the front and rear ends of the metal frame 11. The plug-in frame 12 is movably connected to the inward side surface of the support block 131.

[0028] When in use, push the wind turbine tower 2 downwards, and the bottom end of the wind turbine tower 2 connects with the top of the support base 3.

[0029] The surface of the wind turbine tower 2 is connected to the surface of the moving roller 133. The wind turbine tower 2 can push the moving roller 133 to move up and down. The moving roller 133 can drive the metal arm 132 to rotate. The metal arm 132 drives the connecting piece 136 to move up and down.

[0030] The connector 136 slides on the surface of the metal slide bar 135. At the same time, the connector 136 can pull the helical spring 134, and the metal slide bar 135 and the limiting cover plate 137 can push the connector 136 to perform a limiting operation.

[0031] The movable roller 133 and the supporting base 3 can clamp and fix the wind turbine tower 2, which can protect the safety of the wind turbine tower 2 and prevent the wind turbine tower 2 from deforming.

[0032] When the electric push rod 14 is activated, the internal piston rod of the electric push rod 14 can drive the limiting plug 15 to one end outward, so that the limiting plug 15 is disengaged from the metal frame 11 and the support base 3, thereby loosening the connection between the metal frame 11 and the support base 3.

[0033] Pull the support base 3 upwards, and the support base 3 will move upwards along the inner wall surface of the metal frame 11, so that support bases of different specifications can be disassembled and replaced, which can increase the service life of the support base 3.

[0034] Rotating the nut connects the connector 136 and the metal arm 132 at the inward end of the connector 136, allowing the connector 136 to disengage from the metal arm 132, thus enabling the connector 136 to be disassembled and replaced.

[0035] The connector 136 can drive the helical spring 134, metal slide bar 135 and limit cover 137 to be replaced, and helical springs 134, metal slide bars 135 and limit cover 137 of different specifications can be used.

[0036] Pulling the support block 131 upwards allows it to slide between the front and rear ends of the metal frame 11, making it easy to disassemble and replace.

[0037] The support block 131 can move the metal arm 132, the connector 136 and the movable roller 133 upwards, and the support block 131, the metal arm 132, the movable roller 133 and the connector 136 can be disassembled and replaced.
