Anchoring device and tower

Abstract

The invention relates to an anchoring device and a tower. The anchoring device is used for connecting an inhaul cable and a tower body, the anchoring device comprises an annular body, the annular bodycomprises a base body and a connecting body which are successively arranged in the radial direction of the annular body, the base body is provided with a plurality of installation holes penetrating in the axial direction of the annular body, the installation holes are formed in the circumferential direction of the annular body at intervals, the connecting body is connected with the inhaul cable through connecting positions, and the connecting body is provided with the plurality of connecting positions distributed at intervals in the circumferential direction so as to be connected with the inhaul cable. The embodiment of the invention provides the anchoring device and the tower, the anchoring device can be used for connecting the inhaul cable and the tower body, the weld joint length and the fatigue strength of the tower body cannot be affected, meanwhile, machining and manufacturing of tower barrel sections of the tower body cannot be affected, the cost is low, and the assembling efficiency of a wind generating set can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of wind power, in particular to an anchoring device and a tower. Background technique [0002] In recent years, the application of cable-stayed towers on large wind turbines has become a technical trend. In the prior art, the connection method between the stay cable and the tower body is mostly to directly weld the ear plate on the side wall of the tower body, and then connect the stay cable to the ear plate to realize the connection between the stay cable and the tower body , another way is to prepare the end flanges at both ends of each tower tube section of the tower body into a T-shaped flange, and then connect the cable to the outer edge of the T-shaped flange to realize the connection between the cable and the tower body. the connection between. [0003] Although the above two connection methods can meet the connection requirements between the stay cable and the tower body, there are corresponding de...

AI Technical Summary

Problems solved by technology

[0003] Although the above two connection methods can meet the connection requirements between the cable and the tower body, there are corresponding deficiencies, specifically: the welding of the lug plate on the side wall of the tower body requires a larger profile to adapt to the tension from the pulley. The pre-tightening force of the cable, at this time, the design needs to consider the welding seam of sufficient length to connect the ear plate. On the one hand, the layout is not flexible enough; on the other hand, the ear plate is directly connected to the tower body, which will cause fatigue problems. , and the end flanges of each tower section are set as T-shaped flanges, which increases the processing difficulty of the tower section, and the cost is high, and the tower sections are not easy to level when the tower is formed, which is not conducive to wind turbines. assembly efficiency
