Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the drawings of the present invention are combined to clearly and completely describe the technical solutions in the embodiments of the present invention, and obviously, the described embodiments are some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention. Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention belongs. As used herein, the word "comprising" and similar words are intended to mean that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items.
Problem to prior art existence, the embodiment of the utility model provides an offshore wind power generation machine blade hoist and mount auxiliary device.
Examples
As shown in fig. 1 to 3, an auxiliary device for hoisting an offshore wind turbine blade is used for hoisting a wind turbine blade 1, and comprises a hoisting beam 2; along the length direction of the hanging beam 2, the bottom of the hanging beam 2 is provided with two parallel slide rails 3; each slide rail 3 is connected with a left tape coiling device 4 and a right tape coiling device 5 in a sliding way; blade hanging belts 6 are arranged between the two left tape coiling devices 4 and between the two right tape coiling devices 5; the top of the hanging beam 2 is provided with a plurality of lifting lugs 7, wherein two lifting lugs 7 are provided with hanging beam lifting ropes 8.
The left belt coiling device 4 and the right belt coiling device 5 are electric hoists or winches. The left winding device 4 and the right winding device 5 may be the same or different.
