Non-welding connection structure of fan tower platform

Abstract

The invention discloses a non-welding connection structure of a fan tower platform. The non-welding connection structure comprises a suspension assembly and an anti-swing support assembly, wherein thesuspension assembly consists of a suspension screw rod, a welding force bearing plate, a lower locking nut and an upper locking nut, wherein the two ends of the suspension screw rod are provided withthreads correspondingly, the thread of one end of the two ends is in matched connection with a threaded hole in the inner end surface of a tower flange, and is fastened by using the upper locking nut, the welding force bearing plate is connected with the other end of the suspension screw rod in a welding mode, the tower platform is arranged on the welding force bearing plate, platform pressure isborne by the welding force bearing plate, and the lower locking nut is used for fastening; and the anti-swing support assembly is composed of a supporting base, a supporting screw rod, a rubber gasket and a locking nut, wherein the supporting base is welded at the edge of the tower platform, one end of the supporting screw rod is provided with threads, the other end of the supporting screw rod isa circular truncated cone with an increased stress area, after the rubber gasket is glued on the end face of the circular truncated cone and then the end face of the circular truncated cone abuts against the wall of a tower, the supporting screw rod is fixed on the supporting base through the locking nuts. According to the non-welding connection structure, the fatigue performance of the tower canbe improved, and the material cost of the tower can be reduced.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a non-welded connection structure of a fan tower platform. Background technique [0002] As a clean and sustainable form of energy, wind power has been strongly supported by the state in recent years, which has also promoted the rapid development of domestic wind power. [0003] A wind turbine is mainly composed of a foundation, a tower, a main engine compartment, a hub, and blades. The tower accounts for more than 15% of the total cost of the wind turbine, and the tower is also the most basic guarantee for the safety of the whole machine. So it is necessary to improve the safety of the tower and reduce the cost of the tower. [0004] The strength of wind turbine tower is mainly affected by static strength, buckling strength and fatigue strength. In towers where fatigue is the main control factor, it is particularly important to improve the fatigue performance of ...
