Problems solved by technology
Due to the large thickness and high rigidity of the steel plate at the barrel section, it is necessary to use jacks and simple tooling for fine-tuning at the barrel section, but this method requires manual and continuous movement of the jack, which is labor-intensive and low-efficiency
In addition, when the flange and the barrel joint were assembled in the past, the lower support could not guarantee the flatness of the supporting flange surface. Due to the deformation caused by gravity, the pairing gap between the barrel joint and the flange was too large or insufficient. Uniform, the flatness of the flanges is out of tolerance after assembly, and the flatness of the flanges is out of tolerance, which affects the subsequent welding quality

The invention discloses a device and a method for assembling a flange of a wind power tower drum, the device and the method solve the problems of high labor intensity and low efficiency of assembled flange and drum section in the prior art, and have the beneficial effects of reducing the labor intensity and ensuring the flatness of the flange. The technical scheme is as follows: the device for assembling the flange of the wind power tower drum comprises a support seat, a rotating base and an adjusting arm, wherein the support seat comprises a plurality of support bases, the support bases are arranged spacing a setting distance so as to support the flange and a drum section from the bottom, the rotating base is arranged at the center of the plurality of support bases, the adjusting arm is supported by the rotating base, and the adjusting arm can rotate relatively to the rotating base; the adjusting arm comprises a telescopic rod and a flange hole positioning hook for hanging with a flange hole, and the telescopic rod is arranged at one side of the flange hole positioning hook.
Description
technical field [0001] The invention relates to the field of wind power, in particular to a device and method for assembling flanges of wind power towers. Background technique [0002] The tower tube of the wind power tower is composed of multiple sections, of which a single section is formed by butt welding of multiple tube sections, each tube section is welded by a steel plate reel, and the tube sections at both ends are connected to the flange through the flange ring seam Connection; multiple sections of the tower are connected by flanges. If the flatness of the flange is out of tolerance, it will cause excessive stress on the flange connection and affect the safe operation of the fan. [0003] The flatness of the flange of the tower tube is a key process that restricts the assembly quality of the tower tube. When the flange tube is assembled, the flatness is out of tolerance. The pass rate of the flange flatness after welding is 50%, which needs to be corrected by flame...
