Abstract
This utility model discloses a tooling for replacing dry-type step-up transformers in wind turbine generator sets, aiming to solve the problem of excessively high costs caused by relying on dedicated lifting vessels for transformer replacement inside wind turbine nacelles. The tooling includes a horizontal guide rail, a movable seat sliding on the guide rail, a gantry-shaped hanger mounted on the movable seat, and a hanger connected by cables. The movable seat is equipped with a lifting unit, and the cables are wound around the lifting unit. The gantry-shaped hanger includes an arched mounting sleeve, a mounting base, and a base column. The mounting sleeve is equipped with pulley guides, and a pulley is connected to the top of the hanger. The base column is connected to the movable seat through a cross-shaped base frame, and a diagonal brace with hydraulic rods is provided between the base column and the base frame. This tooling can complete transformer lifting inside the nacelle without the need for a dedicated lifting vessel, reducing costs. Furthermore, the pulley system and stable support structure enable efficient and precise operation, making it suitable for transformer replacement in wind turbine generator sets.
