Description

Technical Field

[0001] This utility model relates to the field of transport vehicle technology, and in particular to a long-distance transport vehicle for wind turbine blades. Background Technology

[0002] Wind turbine blade transport vehicles are specifically designed for the transportation and transfer of wind turbine blades. They eliminate the need for fixing devices and are subjected to significant gravity, preventing mechanical fatigue damage over long-term use and extending the service life of fixing devices. At the same time, they effectively dampen the wind turbine blades during transportation, preventing them from being subjected to excessive vibration and further extending their service life.

[0003] An investigation revealed that a Chinese utility model discloses a wind turbine blade transport vehicle (publication number: CN218882432U). Although the aforementioned patent enables rapid installation of wind turbine blades by inserting the other end of the electric blade on the top surface of the No. 2 fixed seat and the No. 2 rotating gear ring into the No. 2 rotating gear ring, the long length and heavy weight of the wind turbine blades make it very difficult to manually move the blades to align with the screw holes. It is difficult to accurately control the position and may require a lot of time and manpower to repeatedly adjust, reducing work efficiency. Manual operation makes it difficult to ensure that the assembly hole and the blade screw hole are precisely aligned, which may lead to unsmooth bolt installation. Utility Model Content

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Example 1

[0025] Refer to attached figure Figure 1 - Appendix Figure 4 This is the first embodiment of the present invention, which provides a long-distance transport vehicle for wind turbine blades, including a transport vehicle structure 1, a fixing structure 2, and a supporting structure 3. The fixing structure 2 and the supporting structure 3 are respectively installed on the transport vehicle structure 1. The transport vehicle structure 1 includes a first frame 11, a vehicle plate 12, and a second frame 13. The vehicle plate 12 is fixedly installed at one end of the first frame 11, and the other end of the vehicle plate 12 extends into the second frame 13. The vehicle plate 12 and the second frame 13 are slidably connected. Fastening bolts 14 are threaded on the second frame 13, and the top of the vehicle plate 12 is provided with limiting holes 15 that are adapted to the fastening bolts 14.

[0026] The fixed structure 2 includes a base 21, a support 22, and a turntable 24. The base 21 is fixedly installed on one side of the top of the first frame 11, and the support 22 is fixedly installed on the top of the base 21. The surface of the support 22 is provided with an annular groove 23. The bottom end of the turntable 24 is fixedly installed on a slider 25. The slider 25 extends into the annular groove 23, and the slider 25 and the annular groove 23 are slidably connected. The surface of the turntable 24 is provided with an assembly hole 27, and a handle 26 is fixedly installed on the side wall of the turntable 24.

[0027] During use, the second frame 13 is moved according to the length of the blade, so that the plate 12 slides in the second frame 13, thereby adjusting the total length of the first frame 11, plate 12 and second frame 13. Then, the fastening bolt 14 is rotated, and the end of the fastening bolt 14 extends into the limiting hole 15, thereby limiting and fixing the plate 12. The screw hole on the end of the blade is aligned with the mounting hole 27. Because the blade is long and heavy, it is difficult to align the screw hole on the blade with the mounting hole 27. At this time, the handle 26 is pulled, and the handle 26 drives the turntable 24. The turntable 24 rotates in the annular groove 23 through the slider 25, thereby aligning the mounting hole 27 with the screw hole of the blade, making it convenient for the staff to fix the bolts.

[0028] Example 2

[0029] Refer to attached figure Figure 1 and attached Figure 5 This is the second embodiment of the present invention, which differs from the first embodiment in that:

[0030] The support structure 3 includes a fixed frame 31, a fixed cylinder 32, a lead screw 33, a motor 34, and a movable column 35. The fixed frame 31 is fixedly installed on one side of the top of the second frame 13. The fixed cylinder 32 is fixedly installed on the top of the fixed frame 31. The lead screw 33 is rotatably installed on the fixed frame 31 and is inside the fixed cylinder 32. The motor 34 is fixedly installed at the bottom of the fixed frame 31, and the motor shaft of the motor 34 is fixedly connected to the lead screw 33. The movable column 35 is threaded onto the lead screw 33 and is slidably connected to the inner wall of the fixed cylinder 32. A support frame 36 is fixedly installed at the top of the movable column 35. Electric push rods 37 are fixedly installed at both ends of the support frame 36. A clamping seat 38 is fixedly installed on the telescopic rod of the electric push rod 37.

[0031] During use, when the blade is fixed on the turntable 24, the blade is too long and deflects downwards. At this time, the motor 34 is started, and the motor shaft of the motor 34 drives the lead screw 33 to rotate. The lead screw 33 controls the movable column 35 to slide in the fixed cylinder 32. The movable column 35 drives the support frame 36 to move, so that the support frame 36 supports the blade. The electric push rod 37 is started, and the telescopic rod of the electric push rod 37 drives the clamping seat 38 to move. The clamping seat 38 clamps the blade, so that the blade remains stable.
