Embodiment 1

[0020] Such as Figure 2-4 As shown, the present invention provides a kind of hoisting equipment, and this hoisting equipment comprises a crane 1, two bottom beams 12 are suspended on the same side of the crane base 11, and a space for accommodating objects to be hoisted is provided between the two bottom beams 12, The bottom beam 12 is provided with a connection device for connecting the bottom beam 12 with the object to be hoisted and a holding device for holding the object to be hoisted.

[0021] As a specific implementation of this embodiment, the connecting device is more than two hanging ropes 3; one end of the hanging ropes 3 is respectively fixed on the two bottom beams 12, and the other ends of the hanging ropes 3 are provided for hanging on the object to be hoisted. If more than three suspension ropes 3 are selected, the fixed end of the suspension rope 3 and the bottom beam 12 is not on the same straight line to ensure that the crane 1 moves up and down smoothly alo...

Abstract

The invention provides lifting equipment which is sued for installing offshore wind power generation set. The lifting equipment comprises a crane, two bottom beams are overhung on the same side of a base of the crane, a space for accommodating lifted articles is arranged between the two bottom beams, and connection devices for connecting the bottom beams and the lifted articles and clamping devices for clamping the lifted articles are arranged on the bottom beams. The crane can climb on the lifted articles and can progressively lift the lifted articles so as to break through the technical limit that the height of the lifted articles is smaller than that of the self height of the crane in the prior. Compared with the prior art using a large offshore lifting ship to lift the large offshore wind power generation seat, the lifting equipment is low in cost, convenient to construct and high in installation efficiency.

Description

technical field [0001] The invention relates to a hoisting technology, in particular to a hoisting device for a high-power offshore wind turbine. Background technique [0002] Wind energy is a new type of renewable energy with the most mature technology and the most large-scale development conditions in the current clean energy field. In the past ten years, the field of global wind power generation has advanced by leaps and bounds. As land wind farms have fewer and fewer resources that can be developed and utilized, the development of wind farms has shown a trend of developing from land to offshore. Compared with onshore wind power, offshore wind power has many advantages such as not occupying land resources, abundant wind energy resources, close to the load center, and easy grid connection and consumption. High-power offshore wind turbines are usually more than 100 meters high, such as figure 1 As shown, the vertical axis of the offshore wind turbine is composed of multi...
