Welding tool of high-power direct drive generator support for offshore wind power

Abstract

The invention relates to a welding tool of a high-power direct drive generator support for offshore wind power. The welding tool comprises a base, side locating plates and a locating assembly. A plurality of locating blocks for supporting support side plates are fixed to two opposite faces of the two side locating plates correspondingly. First clamping assemblies are arranged at the top ends of the side locating plates, and the locating assembly comprises a plurality of transverse locating plates and a plurality of longitudinal locating plates. The longitudinal locating plates and the side locating plates are parallel, and a plurality of locating grooves are evenly formed in the longitudinal locating plates. The parallel transverse locating plates are fixed between every two adjacent longitudinal locating plates. The transverse locating plates and the longitudinal locating plates are perpendicular, and second clamping assemblies are arranged on the transverse locating plates correspondingly. The high-power direct drive generator support welding tool for offshore wind power can accurately locate the complex-structure high-power direct drive generator support for offshore wind power,and therefore one-time welding forming is achieved, the processing efficiency is greatly improved, and the welding quality is guaranteed.

Description

Technical field: [0001] The invention relates to the technical field of wind power generator processing, in particular to a welding tool for a direct-drive generator support for high-power offshore wind power. Background technique: [0002] Wind turbines use wind power to drive the wind blades to rotate, and then increase the speed of rotation through a speed increaser to drive the generator to generate electricity. Because the structure of the wind-driven generator is comparatively complicated, and the weight is heavier, especially the 8 megawatt high-power wind-driven generator used at sea, its volume is relatively large, therefore, the bearing volume of installing this wind-driven generator is also relatively large. figure 1 It is a structural schematic diagram of a direct-drive generator support for high-power offshore wind power in the prior art, including a support side plate 1, a support front plate or a support rear plate 2, a support horizontal plate 4, and a suppor...

AI Technical Summary

Problems solved by technology

Due to the complex structure and heavy weight of wind power generators, especially the 8 megawatt high-power wind power generators used at sea, their volume is relatively large, so the volume of the support for installing the wind power generators is also relatively large

figure 1 It is a structural schematic diagram of a direct-drive generator support for high-power offshore wind power in the prior art, including a support side plate 1, a support front plate or a support rear plate 2, a support horizontal plate 4, and a support vertical plate 3 , because the overall structure of the support is streamlined and the structure is irregular, the positioning is very troublesome during welding. Generally, the support horizontal plate 4 and the support longitudinal plate 3 are welded together first, and then the support horizontal plate 4 and the support longitudinal plate 3 are welded around the support side plate 1 and the support front plate or the support rear plate 2. During the welding process, multiple positioning is required, and multiple operators are required to cooperate with the welding. The processing efficiency is very low and requires workers. A large amount of labor is required, and the welded product has poor precision because it is assembled many times, and the verticality of the support horizontal plate 4 and support vertical plate 3 is not enough, which provides inconvenience for the installation of the wind turbine
