For this reason, the present utility model is proposed. Utility Model Content

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Please see attached Figure 1 -Attached Figure 4 The support structure of the wind tower transport vehicle includes a transport vehicle pallet 1, and a support assembly is arranged on the top surface of the transport vehicle pallet 1. The support assembly includes two support frames 2 respectively fixed on the top surface of the transport vehicle pallet 1 near the left side and the middle part. A sliding frame 201 is arranged above the transport vehicle pallet 1, and the sliding frame 201 is respectively inserted through the two sides of the two support frames 2. A limiting frame 202 is fixed on the top surface of the transport vehicle pallet 1 near the left side and the top surface of the support frame 2 near the right side. The top surfaces of the support frame 2 and the limiting frame 202 are provided with a clamping groove 207, and one side of the limiting frame 202 is provided with four positioning heads 203.

[0022] In the embodiment, motors 206 are fixed on both sides of the two limit frames 202 that are far away from each other, and the output shafts of the two motors 206 penetrate and extend to the two sides of the two limit frames 202 that are close to each other. Bevel gears are fixed on the output shafts of the motors 206, and four fixed plates 208 are fixed on both sides of the two limit frames 202 that are close to each other. The four fixed plates 208 are arranged in a circular array with the output shafts of the motors 206 as the axis. The internal rotation of the fixed plates 208 is connected to a screw rod 204, and a bevel gear is fixed to one end of the screw rod 204 close to the output shaft of the motor 206. The bevel gear of the screw rod 204 is meshed with the bevel gear of the output shaft of the motor 206, and the positioning head 203 is threadedly connected to the outer wall of the screw rod 204. A hydraulic rod 205 is fixed between the support frames 2, and one end of the telescopic rod of the hydraulic rod 205 is fixed to one side of the limit frame 202. The bottom of the wind tower is effectively supported by setting the support frame 2 and the limit frame 202. The head and tail of the wind tower can be clamped and positioned by the two limit frames 202, and then four positioning heads 203 are used to fit with the inner wall of the wind tower, so as to achieve multi-directional fixation of the wind tower to prevent the wind tower from shaking during transportation. At the same time, the slidable sliding frame 201 is used to drive the limit frame 202 to move horizontally, and the position of the limit frame 202 can be flexibly changed according to wind towers of different lengths to ensure that the tail ends of wind towers of different lengths can be effectively supported and positioned, thereby increasing the applicability of the device.

[0023] In an embodiment, two limiting sleeves 3 are fixed on one side of the fixing plate 208, and a limiting rod 301 is inserted inside the limiting sleeve 3. One end of the limiting rod 301 is fixed to the side of the positioning head 203 close to the fixing plate 208. Through the setting and use of the limiting sleeve 3 and the limiting rod 301, a limiting effect is exerted on the positioning head 203 to prevent the positioning head 203 from rotating due to friction when the screw rod 204 rotates, resulting in the positioning head 203 being unable to fit with the inner wall of the wind tower.

[0024] In the embodiment, a rubber pad 4 is fixed to the side of the positioning head 203 away from the fixing plate 208. By setting and using the rubber pad 4, the positioning head 203 is replaced by the rubber pad 4 to fit with the inner wall of the wind tower. The rubber pad 4 has a larger friction coefficient and the fitting surface can be made tighter.

[0025] In an embodiment, a plurality of anti-skid grooves 5 are provided on the inner wall of the snap-in groove 207. By setting and using the anti-skid grooves 5, the friction between the snap-in groove 207 and the wind tower can be increased, the self-sliding of the wind tower can be reduced, and the stability of the supporting structure can be increased.

[0026] In an embodiment, a plurality of hanging rings 6 are fixed to the top surface of the transport vehicle pallet 1 near the front and rear sides. By providing the hanging rings 6, the staff can additionally tie steel wires to the tower body of the wind tower as needed to increase the stability of the wind tower during transportation.

[0027] Working principle: When in use, the wind tower is lifted to the top surface of the transport vehicle pallet 1 by a crane, and one end of the wind tower is fitted with one side of the limit frame 202 on the top surface of the transport vehicle pallet 1, and the tower body of the wind tower is snapped into the inside of the snap-in groove 207, and then the hydraulic rod 205 is started to drive the sliding frame 201 and the limit frame 202 on its top surface to move horizontally, so that one side of the limit frame 202 is fitted with the other end of the wind tower, and at this time, the motor 206 on the two limit frames 202 is started, and the screw rod 204 rotates under the meshing action of the bevel gear of the screw rod 204 and the bevel gear of the output shaft of the motor 206, and the positioning head 203 is threadedly connected with the outer wall of the screw rod 204, so that the positioning head 203 is fitted with the inner wall of the wind tower, thereby completing the positioning of the wind tower, and then the steel wire is used to pass through the hanging ring 6 to tie the wind tower, and then the wind tower can be transported.

[0028] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
