Abstract

A guiding and positioning device for tower barrel hoisting and abutting joint of a large wind driven generator set comprises an upper hoop device, a lower hoop device and a traction steel wire rope, wherein the upper hoop device and the lower hoop device are circular-arc-shaped and respectively comprise two half hoops symmetrical relative to a central shaft. The upper hoop device comprises an upper positioning and guiding module for positioning an upper tower barrel section and an upper tightening module for adjusting a distance between the two half hoops, wherein the upper positioning and guiding module is respectively installed in the middles of the half hoops, and the upper tightening module is connected between the two half hoops. The lower hoop device comprises a lower positioning and guiding module for positioning a lower tower barrel section and a lower tightening module for adjusting a distance between the two half hoops. One end of the traction steel wire rope penetrates a round hole in an upper hoop device chassis to be fixed in a rope feeding hole, and the other end of the traction steel wire rope penetrates a rope discharging hole and a round hole in a lower hoop device chassis to be connected with a motor on the ground. The guiding and positioning device can guide a flange bolt welded on a tower barrel to achieve quick positioning and is high in hoisting efficiency.

Description

technical field [0001] The invention relates to the field of tower hoisting of a large wind power generating set, and more particularly relates to a hoisting, docking, guiding and positioning device for a tower of a large wind power generating set. Background technique [0002] Before the installation of large-scale wind turbines, the wind turbine tower must be installed first. Its main structure is composed of the foundation ring, the lower section of the tower, the middle section of the tower, and the upper section of the tower. Both ends of each section of the tower are welded with bolt holes. The butt joint installation of the flange and the tower section is to lift the upper tower section by a large-tonnage crane, and after positioning the bolt holes on the flanges of the two sections of the tower, it is connected and fixed by high-strength bolts. Tower hoisting sites are often located in special areas such as seas and mountains, where the wind is strong. In addition, l...
