Blade mounting device of wind driven generator

Abstract

The invention relates to a blade mounting device of a wind driven generator. The blade mounting device comprises a base. Supporting arms and suspension beams are arranged on the two sides of the base correspondingly; the upper ends of the supporting arms are connected with the base; mounting seats are arranged at the lower ends of the supporting arms; and the suspension beams are fixedly connected to the base and arranged oppositely with the corresponding mounting seats. The suspension beams are connected to a crane through a sling; and clamping devices are arranged between the suspension beams and the corresponding mounting seats in a matching mode and used for clamping a blade. An angle adjusting mechanism and a control box are further arranged on the base. The angle adjusting mechanism is used for adjusting the relative heights of the two ends of the base; and the control box is connected with control signals of the clamping devices and the angle adjusting mechanism. The blade mounting device is reasonable in structure arrangement, the rotor blade can be smoothly conveyed and accurately aligned the base of the wind driven generator, and the assembly efficiency is high.

Description

technical field [0001] The invention relates to the technical field of installation devices, in particular to a wind turbine blade installation device. Background technique [0002] A wind turbine is an electrical device that converts wind energy into mechanical energy and mechanical energy into electrical energy. The principle of wind power generation is to use the wind to drive the fan blades to rotate, and then increase the speed of rotation through the speed increaser to promote the generator to generate electricity. The fan blades of the wind turbine can capture the wind and transmit the wind to the rotor shaft. The measurement length of each rotor blade is more than 20 meters, so a crane is required for installation. [0003] The crane is a multi-action hoisting machine for handling heavy objects. Although it can install the fan blades to the blade installation position of the wind turbine, during the assembly process, the stability of the fan blades is not easy to co...

AI Technical Summary

Problems solved by technology

[0003] A crane is a multi-action lifting machine that carries heavy objects. Although it can install the fan blades to the blade installation position of the wind turbine, the stability of the fan blades is not easy to control during the assembly process, and it is difficult to adjust the angular position of the blades in real time. It makes it difficult for the installation end of the blade to be accurately aligned with the connection seat of the wind turbine, resulting in greater difficulty in assembly, longer time consumption, and lower assembly efficiency
