Wind power flange supporting-expanding-type lifting appliance

Abstract

The invention relates to a wind power flange supporting-expanding-type lifting appliance. The wind power flange supporting-expanding-type lifting appliance is characterized by comprising casing pipes, wherein lifting rods which are coaxial with the casing pipes are inserted into the casing pipes; the upper ends of the lifting rods are provided with lifting rings, and the lower ends of the lifting rods are connected with conical column pushing blocks; the lower parts of the conical column pushing blocks are connected with cylindrical spacing blocks; the diameters of the cylindrical spacing blocks are greater than the bottom surface diameters of the conical column pushing blocks; the parts of the casing pipes, which correspond to the conical column pushing blocks, have at least two radial through holes; the lifting rods the lower ends of which push and press the outer periphery surfaces of the conical column pushing blocks are inserted into the radial through holes; the axes of the lifting rods are perpendicular to the axes of the lifting rods. The wind power flange supporting-expanding-type lifting appliance has the advantages of simple structure, convenience in using, time and labor conservation and capability of improving the lifting efficiency.

Description

technical field

[0001] The invention belongs to the technical field of hoisting tools, in particular to a wind power flange expansion type hoisting tool. Background technique

[0002] At present, for the production and transportation of various mechanical equipment or mechanical products, the equipment and tools used for lifting and unloading are inseparable. Some equipment and tools used for lifting and unloading are general-purpose, and some are special-purpose. For equipment or mechanical products of uniform specifications, it is easier to use common equipment and tools to operate, such as: a wind power flange with a diameter of 6-8 meters, the flange has a center hole and mounting holes around the center hole, and its The way to play is to manually wind the lifting wire rope around the circular section of the wind turbine flange and position it, then connect the lifting wire rope to the lifting steel hook set on the loading equipment, and then lift the wind turbine flang...
