Problems solved by technology

At present, there are many procedures for tower spreaders. For tower sections with different cross-sectional sizes, only spreaders that meet the corresponding sizes can be selected, which cannot be used flexibly. This increases the process of replacing the spreader and the cost of the spreader when the tower is hoisted. cost

Abstract

The invention discloses a fan tower hoisting tool and hoisting method. The fan tower hoisting tool comprises a compensation hoisting unit and a telescopic hoisting arm unit, the compensation hoisting unit is arranged above the telescopic hoisting arm unit, the compensation hoisting unit is connected with a hoisting device, and the lower end of the compensation hoisting unit is connected with the telescopic hoisting arm unit; the compensation hoisting unit is used for compensating the inclined motion of the telescopic suspension arm unit and keeping the telescopic suspension arm unit horizontal; and the telescopic suspension arm unit is connected with a tower to be mounted. According to the fan tower hoisting tool and hoisting method, the arm length can be adjusted to adapt to tower of different sizes, moreover, compensation can be provided during hoisting, and the towers are prevented from inclining.

Description

technical field [0001] The invention relates to the technical field of wind power generation equipment installation, in particular to a wind turbine tower hoisting tool and hoisting method. Background technique [0002] At present, the development trend of wind power generators is the increase of single unit capacity, the weight of supporting towers, and the number of tower sections. Since the tower adopts a conical structure, double cranes are usually used for hoisting the tower, that is, a The auxiliary crane cooperates with the main crane to complete the turning, erection and subsequent docking construction of the tower tube. Limited by the distribution of the lifting points of the spreader and the technical level of the construction personnel, there are unreasonable installation of the spreader during the lifting process, the lifting point cannot be found correctly, and the force on the flange is uneven, which may easily damage the flange. , The severely damaged tower m...
