Butt end bracket for long-distance transport of large-scale wind power generation blades

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 ...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the problems existing in the prior art, the present invention proposes a simple structure, which can meet the strength requirements in the long-distance transportation of large wind power blades, and can solve the problem of local deformation of bolts caused by concentrated stress or blockage of inner and outer nuts during the transportation of wind power blades. The problem of cracking, especially the transport bracket that can transport two or more types of wind turbine blades at the same time
