[0027] like Figure 1-4 It is a structural schematic diagram of a wind turbine blade clamping device for ultra-high altitudes in a preferred embodiment of the utility model. In this embodiment, a wind turbine blade clamping device for ultra-high altitudes includes a base 1, and telescopic hydraulic rods 2 are fixedly installed on both sides of the top surface of the base 1. An oil tank 3 is fixedly installed between the two telescopic hydraulic rods 2. An oil pump 4 is fixedly installed on the top of the oil tank 3, and the two sides of the oil pump 4 are connected to the telescopic hydraulic rod 2 through oil pipes. The input and output between the oil tank 3 and the telescopic hydraulic rod 2 are controlled by the oil pump 4, thereby realizing the extension and retraction function of the telescopic hydraulic rod 2. A support frame 5 is fixedly connected to the output end of the telescopic hydraulic rod 2, thereby realizing the function of rising and falling of the support frame 5, and can drive the support frame 5 to move up and down, so that the height of the wind turbine blades can be lifted and lowered, which is convenient for different assembly operations and improves the efficiency of the device. A clamping cavity 51 is opened on the surface of the support frame 5, and a clamping device 10 is connected by rotation in the clamping cavity 51 to realize the clamping and fixing function of the wind turbine blades. Universal wheels 9 are fixedly installed around the bottom surface of the base 1, so that the clamping mechanism 7 can have a short-distance movement function during the clamping process of the wind turbine blades.

[0028] In this embodiment, the clamping device 10 includes a connecting tube 6, a clamping mechanism 7 and a limiting mechanism 8. The connecting tube 6 is assembled in the clamping cavity 51, and the outer wall of the connecting tube 6 is connected to the clamping cavity 51 by a plurality of balls 52, so that the connecting tube 6 can achieve a 360-degree rotation function and has better adaptability. The clamping mechanism 7 is fixedly installed at the upper and lower ends of the inner wall of the connecting tube 6. The mechanism is designed to achieve a clamping effect on the wind turbine blades. The limiting mechanism 8 is fixedly installed on the left and right sides of the inner wall of the connecting tube 6. The mechanism is designed to achieve a limiting effect on the wind turbine blades.

[0029] In this embodiment, the clamping mechanism 7 includes a fixed seat 71, a connecting rod 72 and a clamping assembly 75. The fixed seat 71 is fixedly connected to the inner wall of the connecting tube 6. A connecting hole 711 is opened on the surface of one end of the fixed seat 71. The connecting rod 72 is threadedly connected to the inner thread of the connecting hole 711. This structural design realizes the extension and retraction adjustment function of the connecting rod 72 by rotating the connecting rod 72. This structural design can cope with wind turbine blades of various sizes, and the clamping assembly 75 is fixedly connected to the end of the connecting rod 72 away from the fixed seat 71.

[0030] In this embodiment, the clamping assembly 75 includes a fixed block 73 and a contact assembly 74. The fixed block 73 is fixedly connected to the surface of the connecting rod 72. A notch 731 is provided on the surface of the fixed block 73. The inner wall of the notch 731 is provided with rotating openings 732 on both sides. The contact assembly 74 is rotatably connected in the rotating opening 732. The above structural design enables the contact assembly 74 to have the function of multi-angle rotation, which can cope with wind turbine blades of various sizes and shapes, so that the contact assembly 74 is more closely fitted to the surface of the wind turbine blade.

[0031] In this embodiment, the contact assembly 74 includes a connecting block 741 and a contact block 742. The upper sides of the outer wall of the connecting block 741 are rotatably connected to the rotating opening 732, and the contact block 742 is movably connected to the lower side of the connecting block 741. Its structural design can pull the contact block 742 toward the outer walls of the connecting block 741 according to actual needs, so that the contact block 742 can be extended outward, which can cope with the functions of wind turbine blades of various sizes and shapes.

[0032] In this embodiment, the limiting mechanism 8 includes a limiting block 81 and a limiting plate 82. The limiting block 81 is fixedly connected to the inner wall of the connecting tube 6. A movable opening 83 is opened in the limiting block 81. Two limiting plates 82 are rotatably connected in the movable opening 83, so that the distance between the two limiting plates 82 can be adjusted, and the two limiting plates 82 are connected by gear meshing, so that one limiting plate 82 can be adjusted to drive the other limiting plate 82, and has the function of synchronous adjustment.

[0033] In this embodiment, the surfaces of the contact block 742 and the limit plate 82 are fixedly connected with rubber blocks 743. This structural design enables the contact block 742 and the limit plate 82 to have a certain buffering effect on the surface of the wind turbine blade, effectively preventing the possibility of damage to the surface of the wind turbine blade.

[0034] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make several simple deductions or substitutions, which should be regarded as belonging to the scope of protection determined by the claims submitted for the utility model.
