Wind energy is a kind of usable energy provided to human beings by air flow. It is abundant, widely distributed, clean and belongs to renewable energy. At present, the main means of utilizing wind energy is wind power generation. Wind power generation refers to converting the kinetic energy of wind into electrical energy. Wind power generation is very environmentally friendly and generates huge amounts of electricity. As one of the clean energy with the best development prospects, wind power generation is widely promoted and applied. Wind power generation technology is inseparable from the support of wind turbines, and wind turbine blades are important components of wind turbines. In the production and manufacturing process, wind turbine blades need to go through processes such as laying, pouring, mold closing, demoulding, and post-processing. In the post-processing process, brackets or transfer vehicles are needed, so blades are frequently transported. At present, when transporting blades, cranes or gantry frames are usually used to hoist the blades, and then they are placed on brackets or transfer vehicles. With the rapid development of the wind turbine blade industry, the diameter of the root of wind turbine blades is getting larger and larger.

DETAILED DESCRIPTION

The utility model will be further described below in conjunction with the accompanying drawings.

A wind turbine blade root lifting and transfer vehicle as shown in Figures 1 and 2 includes a trapezoidal fixing frame 1 and a hydraulic cylinder 5. The front side of the trapezoidal fixing frame 1 is detachably connected to a mounting plate 2, and a plurality of threaded holes 3 are provided on the mounting plate 2. The bottoms of both sides of the trapezoidal fixing frame 1 are fixedly connected to the output ends of the hydraulic cylinder 5. A balancing plate 6 is fixedly connected to the bottom of the hydraulic cylinder 5, and a universal wheel 7 is fixedly connected to the bottom of the balancing plate 6 by bolts.

It should be noted that, since there is no need to use connecting bolts to fix the mounting plate 2 to the screw holes on the root of the wind turbine blade one by one, the structure of the mounting plate 2 can be two symmetrically arranged inclined plates, on which threaded holes 3 corresponding to the screw holes on the root of the wind turbine blade are arranged in an arc shape at intervals; in addition, the structure of the mounting plate 2 can also be set to a flange structure corresponding to the root of the wind turbine blade.

In order to increase the stability of the equipment operation and ensure that the equipment can drive the blade roots of wind turbine blades to achieve stable lifting and lowering, a guide assembly is fixedly connected to the balance plate 6 outside the hydraulic cylinder 5, and the upper end of the guide assembly is fixedly connected to the bottom of the trapezoidal fixed frame 1. The guide assembly includes a slide bar 9 and a slide sleeve 8, the slide sleeve 8 is fixedly connected to the balance plate 6, the slide bar 9 is fixedly connected to the bottom of the trapezoidal fixed frame 1, and the lower end of the slide bar 9 is slidably connected to the slide sleeve 8. The number of guide assemblies on both sides of the trapezoidal fixed frame 1 is not less than one.

In order to facilitate the disassembly, assembly and replacement of the mounting plate 2 so as to achieve rapid replacement when the device is used on blades of different specifications and models and improve work efficiency, the mounting plate 2 is connected to the trapezoidal fixing frame 1 by bolts 4 .

In order to ensure the stability and safety of the equipment during operation and avoid major losses caused by a problem with a hydraulic cylinder 5, two hydraulic cylinders 5 are provided on both sides of the trapezoidal fixed frame 1, and the top of the hydraulic cylinder 5 is connected to the trapezoidal fixed frame 1 through a connecting rod 11. The hydraulic cylinder 5 is fixedly connected to the balance plate 6 through a connecting bolt, and one end of the connecting rod 11 is connected and fixed to the hydraulic cylinder 5 through a connecting bolt.

It should be noted that the operation of the hydraulic cylinder 5 requires the use of a hydraulic pump at the same time, so the hydraulic cylinder 5 of the present device needs to be connected to the hydraulic pump through a pipeline. The hydraulic pump can be connected to the balance board 6 or placed in the workshop. The hydraulic cylinder 5 and the hydraulic pump are both existing devices, and their connection relationship is also existing technology. Therefore, they will not be described in detail in this embodiment.

In order to increase the strength of the device and improve the firmness of the equipment, a reinforcing rod 10 is fixedly connected to the trapezoidal fixed frame 1. In order to further improve the strength of the device, a reinforcing rod 12 is fixedly connected between the hydraulic cylinder 5 and the sliding sleeve 8.

It should be noted that, due to the large number of wind turbine blades, the diameters of the blade roots of wind turbine blades are different. This device is equipped with a plurality of mounting plates 2 corresponding to wind turbine blades of different specifications and models. When in use, the corresponding mounting plate 2 can be replaced according to the wind turbine blade model. In this embodiment, the mounting plate 2 is connected to the trapezoidal fixing frame 1 by bolts 4, so as to facilitate the replacement of the mounting plate 2. At the same time, when the device is in use, the device is towed and moved by the AGV trolley.

The working process of this embodiment is as follows:

After the wind turbine blade is demoulded, it needs to enter the post-processing process. At this time, the AGV trolley is used to pull the device to the root of the wind turbine blade, and the hydraulic cylinder 5 is controlled to lift and lower to drive the trapezoidal fixing frame 1 and the mounting plate 2 to adjust the height. During the lifting and lowering process of the hydraulic cylinder 5, the slide bar 9 will slide in the sleeve 8 to achieve guidance and improve the operating stability of the device. When the height is adjusted to the position of the threaded hole 3 corresponding to the screw hole position on the wind turbine blade root, the distance between the device and the wind turbine blade root is fine-tuned. After adjustment, the root bolt is used to penetrate the threaded hole 3 to fix the mounting plate 2 to the wind turbine blade root. After that, the wind turbine blade can be lifted or transported according to the process. When it is necessary to apply this device to wind turbine blades of different specifications and models, due to the different root diameters, it is necessary to replace the corresponding model of the mounting plate 2. Loosen the bolt 4 to remove the original mounting plate 2 and then install the corresponding mounting plate 2. At the same time, when using this device, a matching blade tip device is required.
