Abstract

A butt end bracket for the long-distance transport of a large-scale wind power generation blades mainly comprises a blade butt end bracket base (1), blade bearing rods (2 and 3), a hydraulic jack mechanism (4), bolt holes (5), a following support plate (6) and a rubber pad (7), an upper group of and a lower group of different specifications and numbers of arc-shaped large-gap bolt holes (5) which are corresponding to different models of butt end bolts of wind generation blades and can meet the requirements of the same circumference diameter and different heights and positions are formed in the blade bearing rods (2 and 3), so that gaps exist at the periphery of the bolts at the butt ends of the wind generation blades corresponding to the bolt holes (5), so that the deformation and blocking cracking caused by large intensive stress of the bolts in the transport process can be reduced. According to the disclosed butt end bracket for the transportation, the installation, the fixation and the transportation of more than two kinds of wind generation blades are met, wherein the diameters of the butt end surfaces of the wind generation blades are 110mm, and 64 bolts are uniformly distributed on each wind generation blade, the problem that an existing butt end bracket for transportation only can transport one model of wind generation blade once is solved, the exchanging efficiency of the transportation bracket is promoted, and the funding is reduced.

Description

technical field

[0001] The invention belongs to the technical field of wind power generation blade transportation, and mainly relates to a root end bracket for long-distance transportation of large wind power generation blades. Background technique

[0002] At present, most of the root-end load-bearing transport brackets used in the long-distance transportation of wind power blades adopt a steel riveted weldment structure, and the bolts at the root of the wind power blades are fixed and limited through hole shafts. During transportation, the load-bearing transport bracket at the root end is fixed together with the wind turbine blades to form a stable whole. The hole-axis fit is based on making the distribution of the bolt holes on the root-end load-bearing transport bracket have a fixed corresponding relationship with the diameter of the root of the wind turbine blade and the uniform number of bolts. The bolt holes of the root-end load-bearing transport bracket used in ...

Embodiment Construction

[0009] like figure 1 , figure 2 As shown, a root end bracket for long-distance transportation of a large-scale wind power generation blade according to the present invention is mainly composed of a blade root end bracket base 1, a blade load-bearing rod 2, a blade load-bearing rod 3, a hydraulic jack mechanism 4, a bolt hole 5, It is composed of supporting plate 6 and rubber pad 7; the two ends and the center of the blade root end bracket base 1 are respectively provided with blade load-bearing rods (2, 3), and the blade load-bearing rods (2, 3) are divided into upper and lower groups. Bolt holes 5 that can meet two different specifications, quantities, and distributions of different types of wind turbine blade root bolts that can meet the same circumference diameter, height, and position are processed; 5. The wind turbine blade is fixed on the blade load-bearing rod (2, 3) through the cooperation of the hole shaft. The hydraulic jack mechanism 4 is installed at the center ...
