Embodiment Construction

[0057]The following examples can enable those skilled in the art to understand the present invention more comprehensively, but the present invention is not limited to the scope of the described examples.

[0058] The construction process of the wind power tower of the present invention is specifically realized through the following steps: including the fabrication of sectioned tube sections, installation of tower tube flanges and tower tube assembly processes.

[0059] 1. Segmented cylinder section production:

[0060] Including raw material incoming inspection, material re-inspection, steel plate pretreatment, CNC cutting and blanking, dimensional inspection, groove processing, rounding, welding longitudinal seam, round calibration, cylindrical section ellipticity measurement, 100% UT and T-shaped seam 100% MT testing process.

[0061] In the production of segmented cylinders, the requirements for the blanking of cylinder joints are: the full-time quality inspector of the qu...

Abstract

The invention relates to a construction process of a wind power tower tube. The construction process comprises the procedures of sectioned tube section manufacturing, tower tube flange installation, and tower tube assembly; sectioned tube section manufacturing comprises the procedures of factory inspection of raw materials, material reinspection, pretreatment of a steel plate, numerical control cutting blanking, dimensional inspection, groove machining, circle rolling, group-welding of longitudinal joints, circle rectifying, measuring of tube section ovality, 100%UT detection and T-shaped seam100%MT detection; tower tube flange installation is achieved through the procedures of flange detection, tower tube detection, flange fixing, tube body installation, welding measuring, bottom flangeassembly, tube body connection, bolt connection, tube body positioning welding and detection after welding jointly; and tower tube assembly comprises the procedures of grouping of tube sections and flange nipples, inspection, welding, 100% UT detection, inspection, drawing of position lines of inner parts, inspection, group-welding of the inner parts, anticorrosion treatment, assembly of the innerparts, packing and forwarding. The construction process has the advantage of being high in precision.

Description

technical field [0001] The invention relates to a tower, in particular to a construction process of a wind power tower. Background technique [0002] In recent years, global energy and environmental issues have become increasingly severe, and the wind power industry has entered a period of rapid development. Since the energy efficiency of offshore wind power energy is much higher than that of land wind farms, and it does not occupy land, it is less restricted by problems such as landscape, noise and electromagnetic waves, so the future development of offshore wind power will surely achieve leapfrog development. [0003] As the foundation of wind turbines, the importance of wind power towers is self-evident. During the construction of wind power towers, the ellipticity and straightness control of the tower and the welding heat treatment of thick plates have always been the difficulties in the construction of the tower. Different technological processes and different operati...
