Description

Technical Field

[0001] This utility model relates to the field of large equipment transport vehicles, and in particular to a split-type wind turbine blade transport vehicle. Background Technology

[0002] In existing technologies, wind turbine blade transportation mainly utilizes integral flatbed trailers or special blade transport vehicles. Integral vehicles often require large hoisting equipment for positioning and lifting during blade loading and unloading, resulting in complex operations, low efficiency, and demanding site requirements. Furthermore, when traveling unloaded after transport, the vehicle's structural utilization is low, leading to poor economic efficiency. While some vehicles possess certain blade attitude adjustment capabilities, the adjustment range is limited, making it difficult to adapt to real-time obstacle avoidance requirements in complex road conditions. Utility Model Content

[0004] A split-type wind turbine blade transport vehicle, comprising: The front body; and The rear body is used to carry the wind turbine blades; The front vehicle body is equipped with a mounting plate for fixing and installing wind turbine blades and a drive mechanism for changing the pitch angle of the mounting plate. The front vehicle body and the rear vehicle body are connected in a detachable manner.

[0005] A mounting bracket is provided on the front vehicle body, and the mounting plate and the drive mechanism are both hinged to the mounting bracket; The mounting bracket is hinged to the front vehicle body, thereby allowing the height of the mounting plate to be adjusted to facilitate docking between the front and rear vehicle bodies.

[0006] A support frame is installed on the rear of the vehicle.

[0007] A slewing platform is installed on the rear vehicle body, and a support frame is installed on the slewing platform.

[0008] A slewing platform is mounted on the front vehicle body, and the hinge point of the mounting bracket is located on the slewing platform.

[0009] The driving mechanism is a hydraulic cylinder or a pneumatic cylinder.

[0010] The front body has a gooseneck.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the front and rear vehicle bodies of this utility model are detachably connected; when transporting blades, the two are separated, and each bears the function of fixing the blade root and bearing the main body of the blade, respectively, with a strong structural focus; after transportation, the two can be quickly connected, and the front vehicle body acts as a tractor to pull the rear vehicle body to travel unloaded, which improves the overall utilization rate of the vehicle and the convenience of relocation, and reduces operating costs.

[0012] The pitch angle of the mounting plate can be actively controlled by a drive mechanism mounted on the front of the vehicle, allowing for easy raising or lowering of the blade tip. This enables the rear vehicle to easily move under the blade to support it or remove it from below to unload it, reducing reliance on large external hoisting equipment, simplifying loading and unloading processes, and improving operational efficiency and safety.

[0015] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0016] Example 1 like Figures 1-3 As shown in the figure, the present invention provides a split wind turbine blade transport vehicle, including a front vehicle body 1 and a rear vehicle body 2. The front end of the front vehicle body 1 is a gooseneck 3. The two are split structures and are connected in a detachable manner. For example, the detachable manner is achieved by opening limit holes on both the front vehicle body 1 and the rear vehicle body 2 and inserting limit pins to realize the connection between the front vehicle body 1 and the rear vehicle body 2. When transporting wind turbine blades, the front vehicle body 1 and the rear vehicle body 2 are separated. The ends of the wind turbine blades are installed on the front vehicle body 1 and carried by the rear vehicle body 2. After transportation, the front vehicle body 1 and the rear vehicle body 2 can be connected to facilitate the traction of the rear vehicle body 2.

[0017] Example 2 like Figures 1-3As shown, this embodiment proposes a split-type wind turbine blade transport vehicle based on embodiment one, which includes a front vehicle body 1 and a rear vehicle body 2. The front vehicle body 1 is equipped with an mounting plate 4, which is used to fix and connect to the end of the wind turbine blade. The mounting plate 4 has at least a fixing hole or fixing protrusion corresponding to the wind turbine blade. Due to the different shapes of the wind turbine blades, the positions of the fixing holes or fixing protrusions are different, so they will not be illustrated here. The rear vehicle body 2 is used to carry the wind turbine blades, and a support frame 7 is provided on it. In order to facilitate the placement of the wind turbine blades on the rear vehicle body 2, this embodiment also has a drive mechanism 5. The drive mechanism 5 is used to adjust the pitch angle of the mounting plate 4, so that the tail end of the wind turbine blades mounted on the mounting plate 4 can be raised, so that the rear vehicle body 2 can move to the bottom of the wind turbine blades and complete the purpose of placing the wind turbine blades on the rear vehicle body 2. In this embodiment, the drive mechanism 5 is a hydraulic cylinder or a pneumatic cylinder. Its output end is connected to the mounting plate 4, which is hinged to the front vehicle body 1. The drive mechanism 5 is also hinged to the front vehicle body 1. When the output end of the drive mechanism 5 extends, the mounting plate 4 swings around the hinge point, thereby realizing the adjustment of the pitch angle.

[0018] Example 3 like Figures 1-3 As shown, this embodiment proposes a split-type wind turbine blade transport vehicle based on embodiment two, which includes a front vehicle body 1 and a rear vehicle body 2. For the transport of large components such as wind turbine blades, in order to meet the height restriction requirements and driving stability, it is necessary to lower the vehicle center. Based on this, the lower the lowest position of the mounting plate 4 is, the better. However, after the transport is completed, it will affect the docking of the front and rear vehicles. Based on this, a mounting frame 6 is hinged on the front vehicle body 1 in this embodiment, and the mounting plate 4 and the drive mechanism 5 are both hinged on the mounting frame 6. After the transport is completed, the mounting frame 6 can be lifted up, and then the front vehicle body 1 and the rear vehicle body 2 can be docked. The mounting frame 6 can be placed directly on the rear vehicle body 2 without affecting the connection between the two, which is conducive to the finishing work after the transport is completed. The hinge structure is an existing connection structure, so it will not be described in detail here. For the stability of the structure, those skilled in the art can increase the thickness or replace it with a high-strength material to cope with the transportation of large components. The simplification of the hinge structure in the attached drawings only shows its specific location and does not represent the actual structure. In addition, turns will occur during transportation. To reduce the turning radius, both the front vehicle body 1 and the rear vehicle body 2 should have a turning platform. The hinge point of the mounting frame 6 is located on the turning platform of the front vehicle body 1, while the turning platform of the rear vehicle body 2 is equipped with a support frame 7. The support frame 7 has a certain length in the vehicle body direction, which can achieve effective contact and support for the wind turbine blades. When a turn is required, the turning platform is manually opened so that the wind turbine blades can swing. It is locked during normal driving. The turning platform can use existing technology, so it will not be described in detail here. In addition, each wheel of the wind turbine transport vehicle should have independent steering function, which is existing technology and will not be elaborated here.

[0019] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit and essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0020] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
