Problems solved by technology
Generally, the blades of wind turbines are three pieces. For the independent electronically controlled pitch system, there are three pitch control cabinets, which are respectively installed inside the hub and correspond to the installation surfaces of the three blades. Considering the overall design Requirements, the space inside the hub is relatively narrow, and the pitch control cabinet itself has no design for hoisting and positioning points, which brings certain difficulties to installation, inconvenient operation, and small space, which is not suitable for mass production

Description
technical field [0001] The invention relates to a sling, in particular to a sling for a pitch control cabinet used for installing a pitch control cabinet in a pitch control system in the wind power generation industry. Background technique [0002] The pitch system of wind turbines is divided into two types: hydraulic control pitch and electric control pitch, and the pitch is divided into independent pitch and integral pitch. Generally, the blades of wind turbines are three pieces. For the independent electronically controlled pitch system, there are three pitch control cabinets, which are respectively installed inside the hub and correspond to the installation surfaces of the three blades. Considering the overall design Requirements, the space inside the hub is relatively narrow, and the pitch control cabinet itself has no design for hoisting and positioning points, which brings certain difficulties to installation, inconvenient operation, and small space, which is not suit...
