Abstract

The invention relates to the technical field of test instruments, in particular to an assembling tire device and method for wind power tower flanges. The assembling tire device comprises a tire columnand multiple supporting rod assemblies, and the tire column is used for positioning the supporting rod assemblies; the supporting rod assemblies are uniformly distributed on the outer side face of the tire column through radiating, and the distances between the ends, away from the tire column, of the supporting rod assemblies and the center axis of the tire column are equal; the ends, away from the tire column, of the supporting rod assemblies can be driven by a driving part to stretch and retract by an equal length, the tire column is of a cylindrical structure, the supporting rod assembliescomprise sleeves, one end of each sleeve is fixedly arranged on the outer side face of the tire column, the multiple sleeves are arranged through radiating and internally provided with supporting rods, and the supporting rods can conduct reciprocating sliding along the axes of the sleeves and are fixed to set positions. With the assembling tire device and method, the problems can be solved that during production, cylinder segments are not easy to round through correction, and since a jack is adopted for rounding-correcting assembling, the planeness of the welded flanges is poor.

Description

technical field [0001] The invention belongs to the technical field of wind power, and in particular relates to a device and method for aligning flanges of a wind power tower. Background technique [0002] The steel wind power tower frame is assembled and welded by the steel structure tube section, generally divided into 3-6 sections, and the two ends of each section need to be assembled and welded with steel flanges, and the connection between the different sections of the tube section is realized through the flange , the flatness of the flange end face directly affects the installation difficulty and installation quality of the tower. [0003] In the actual production process, there are often some cylindrical joints with large plate thickness that cannot be calibrated. When the cylindrical joints and flanges are installed, they cannot be directly assembled. The assembly is often completed by jacking and other strong assembly methods. However, this method There is residual...
