Large wind turbine pitch gearbox installation tool

Abstract

The invention discloses a variable pitch gearbox installation tool for a large-scale wind turbine. The variable pitch gearbox installation tool comprises a sling body, a rotary flange plate, an adjusting handle, a counter weight and an adjusting slide block, wherein a lifting lug and an unloading lug are arranged on the sling body; the adjusting handle is arranged on the rotary flange plate; a rotating shaft is arranged on the sling body; a through hole is formed in the rotary flange plate; the rotating shaft penetrates through the through hole of the rotary flange plate, so that the rotary flange plate can rotate around the rotating shaft; the lifting lug is arranged between the rotary flange plate and the unloading lug; the adjusting slide block is arranged between the lifting lug and the unloading lug; and the counter weight is suspended on the sling body and limited by the adjusting slide block. According to the variable pitch gearbox installation tool disclosed by the invention, the problems existing in the traditional variable pitch gearbox installation such as complicated installation processes, low efficiency and high labor intensity can be solved, the aims of convenience in installation, high efficiency and low labor intensity are achieved, and the safety and rapidness of wheel hub assembly are guaranteed.

Description

technical field [0001] The invention relates to a novel tool for hoisting and installing a pitch-variable gearbox of a large-scale wind power generating set. Background technique [0002] The pitch system is an important part of the wind turbine blade attitude adjustment, and the pitch efficiency directly affects the power generation efficiency of the wind turbine and ensures the safety of the wind turbine under severe working conditions. When the blade is pitched, the pitch motor drives the pitch gearbox and then drives the pitch bearing to complete the pitch action. Due to the limitation of the size of the wind turbine hub, the internal components of the hub are compactly arranged, which makes the installation space of the pitch gearbox narrow and difficult to install. [0003] Due to the particularity of the internal space of the wind hub, the traditional pitch gearbox spreader has a series of problems in use, such as bulky, complex structure, difficult operation, and hi...
