Single-blade mounting lifting tool of wind generating set

Abstract

The invention relates to a single-blade installation hanger for a wind power generating set. The main boom is installed in the middle of the main girder body. The lower end of the main boom is supported on the lower end of the main girder by a pin shaft and can rotate around the pin shaft. There is also a tilting cylinder between the main beam and the two ends of the tilting cylinder are respectively hinged on the lower end of the main beam and the middle part of the main boom. The two ends of the main beam are respectively equipped with blade clamping devices, which are adjusted by the expansion and contraction of the tilting cylinder. The hoisting angle between the main boom 2 and the main beam body, so as to realize the inclination angle change of the blade clamped in the blade clamping device in the air -30°~30°; the rear end of the upper clamp and the lower clamp of the blade clamping device The clamping cylinder and the adjusting cylinder are respectively installed between the clamping column and the two ends of the adjusting cylinder are respectively hinged on the upper part of the clamping column and the rear end of the lower clamp, and the two ends of the clamping cylinder are respectively hinged on the middle and upper part of the clamping column. On the rear end of the clamp; the upper clamp and the lower clamp realize closing and angle adjustment by adjusting the expansion and contraction of the oil cylinder and the clamping oil cylinder.

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...
