Single-blade mounting lifting tool of wind generating set

Abstract

The invention relates to a single-blade mounting lifting tool of a wind generating set. A main lifting arm is mounted in the middle of a main beam. The lower end of the main lifting arm is supported at the lower end of the main beam through a pin shaft and can rotate around the pin shaft. An oblique oil cylinder is further mounted between the main lifting arm and the main beam. The two ends of theoblique oil cylinder are hinged to the lower end of the main beam and the middle of the main lifting arm correspondingly. Blade clamping devices are mounted at the two ends of the main beam correspondingly. The lifting angle between the main lifting arm 2 and the main beam is adjusted through stretching and contracting of the oblique oil cylinder, and therefore a blade clamped in the blade clamping devices can change in air by a dip angle ranging from -30 degrees to 30 degrees. A clamping oil cylinder and an adjusting oil cylinder are mounted between the rear end of upper pincers of each blade clamping device and a clamping column and between the rear end of lower pincers of the corresponding blade clamping device and the corresponding clamping column correspondingly. The two ends of eachadjusting oil cylinder are hinged to the upper portion of the corresponding clamping column and the rear end of the corresponding lower pincers correspondingly. The two ends of each clamping oil cylinder are hinged to the middle portion of the corresponding clamping column and the rear end of the corresponding upper pincers correspondingly. The upper pincers and the lower pincers achieve closingand angle adjusting through stretching and contracting of the adjusting oil cylinders and the clamping oil cylinders.

Description

technical field [0001] The invention relates to a single-blade mounting sling for a wind power generator set, in particular to a single-blade mounting sling suitable for both double-fed and direct-drive wind turbines, and belongs to the technical field of wind power blade hoisting. Background technique [0002] In recent years, the wind power market has developed rapidly. In general, the direct drive fan does not have a gear box, so it cannot be turned, and the blade needs to be tilted by 30°, so that the blade can be hoisted on a single blade on a model that does not have a turning. [0003] Various wind turbine blade hoisting mechanisms appearing in the market at present. This hoisting mechanism has high cost, single function, poor stability, and does not have the function of installing a single blade at an angle of 30°. [0004] Therefore, a lifting device with a simple structure is designed, which is easy to install and disassemble on site, and can realize single-blade...

AI Technical Summary

Problems solved by technology

[0005] The present invention is to solve the single-blade hoisting problem of the wind power generator set, especially the single-blade hoisting problem of the fan without the turning function, and provides a single-blade installation hanger of the wind power generator set, through the expansion and contraction of the tilting oil cylinder, that is It can realize the change of the included angle between the main boom and the main beam body, so as to realize the inclination angle change of the blade in the air from -30° to 30°, and realize the closing and angle adjustment of the upper clamp and the lower clamp by adjusting the expansion and contraction of the oil cylinder and the clamping cylinder
