Special crane for transporting fan blade

Abstract

The invention provides a special crane for transporting a fan blade. The special crane comprises a main structure, a cart system, a hoisting system, a hanger transverse movement system, a power station and an operation platform, wherein the main structure is in a box type beam structure; the cart system comprises an operation mechanism and a rotary mechanism and is a whole machine walking and steering system; the hoisting system is a system of hoisting a lifting hook group by a winch through a steel wire rope and a pulley wheel; the hanger transverse movement system is a system of moving a hanger trolley by a winch through a steel wire rope and a pulley wheel; the power station comprises a diesel generator and a hydraulic pump station; the operation platform is provided with a command switch for the movement operation of each mechanism and the command switch is used for controlling working states of a hoisting winch, a transverse movement winch, a hydraulic motor and a hydraulic rotary speed reducer. A hoisting method is used for transporting the fan blade by two special cranes to carry out combined operation and hoisting. The special crane for transporting the fan blade has the beneficial effects that cross hanging, in-situ any angle steering, frontward movement, and multilayered and multi-array stacking can be realized; the special crane is flexible to move, high in maneuverability and high in efficiency; the special crane is compact in structure, light in self weight, good in ground adaptability, and safe and reliable to hoist.

Description

Technical field

[0001] The invention belongs to the technical field of hoisting machinery, and in particular relates to a special crane for conveying fan blades. Background technique

[0002] The fan blades of large-scale wind power generation equipment have the characteristics of special materials, easy damage, irregular shapes, long and non-uniform dimensions. With the vigorous promotion of wind power generation, wind turbine blades have achieved professional, batch, and flow-through production. Some companies have begun to plan dedicated blade storage yards or docks, and transport the assembled wind turbine blades from the factory to the storage yard or dock. , There are regular stockpiles, and when needed, they will be shipped to the installation site by special vehicles or ships. In the prior art, two truck cranes or crawler cranes are generally used for hoisting and transporting large wind turbine blades simultaneously in the form of a single boom. The disadvantages of th...
