Assembly tool capable of replacing gearbox overhead without dismounting wind wheel

Abstract

The invention discloses an assembly tool capable of replacing a gearbox overhead without dismounting a wind wheel, and belongs to the assembly field. The assembly tool comprises a mobile mechanism group and a fixing mechanism used for supporting and fixing the mobile mechanism group, wherein the mobile mechanism group comprises an X-axis regulating mechanism, a Y-axis regulating mechanism and a Z-axis regulating mechanism; the X-axis regulating mechanism comprises at least two X-axis rails which are arranged in parallel and at least four mobile blocks capable of moving on the X-axis rails, and a connecting frame is arranged between every two mobile blocks; the Y-axis regulating mechanism comprises two parallel supporting transverse frames which are perpendicularly connected with the two connecting frames; a Y-axis slide slot is formed in each supporting transverse frame; a lead screw structure is arranged at each of two ends of each Y-axis slide slot; the Z-axis regulating mechanism comprises an adjustable connector which is connected on a mobile part for connecting and fixing a to-be-assembled object; and the X-axis rails are arranged on a supporting longitudinal beam on the upper part of the fixed mechanism. According to the assembly tool disclosed by the invention, the position and speed of the gearbox are precisely controlled through three dimensions, so that the purpose of replacing the gearbox overhead without dismounting the wind wheel is achieved, and therefore, lifting efficiency is improved.

Description

technical field [0001] The invention relates to the field of hoisting, in particular to an assembly tool for replacing a gear box in the air without dismantling the wind wheel. Background technique [0002] The installed capacity of wind power in my country is huge, and the mainstream model is double-fed unit, in which the gearbox structure is indispensable. The gearbox is composed of transmission parts such as gears and bearings, and auxiliary parts such as cooling and lubrication. Due to poor load stability and high turbulence in the wind field, it may be necessary to replace the gearbox. [0003] At present, for replacing the gearbox in the air, most manufacturers first remove the wind wheel, then hoist the transmission chain to the ground, and hoist the gearbox back to the nacelle after the gearbox is replaced on the ground. This process has many steps, is time-consuming and laborious, and has no advantages in terms of timeliness and economy. Some over-the-air replace...

This process has many steps, is time-consuming and labor-intensive, and has no advantages in terms of timeliness and economy.

Some in-air replacement solutions for high-speed and intermediate-level components can indeed solve the problem of in-air replacement of components, but there is no good solution for the replacement of the gearbox as a whole
