Technical Field

The invention relates to an assembling lifting appliance of a plugging device for offshore wind power large-diameter single-pile floating transportation.

Background

Offshore wind power generation has become an important new field for developing clean energy in China. The offshore wind turbine generator is becoming larger and larger, and the transportation cost and difficulty are higher and higher. The offshore wind power single pile foundation has the advantages that the diameter is generally more than 5 meters, the length is more than 60 meters, the weight is more than 500 tons, and the offshore wind power single pile foundation can be transported in a marine floating mode on the premise that two ends of a single pile are plugged according to the characteristics of large diameter, long length and heavy weight, so that the purposes of saving cost and improving transportation efficiency are achieved. At present, the single-pile plugging technology is to use a hydraulic drive plugging device to plug the two ends of a single pile. In the plugging mode, when the plugging device is assembled with the single pile, the single pile is in a horizontal placement state, so that the plugging device can be installed at two ends of the single pile only by vertically hoisting the plugging device by means of an assembling lifting appliance.

At present, the mode that a single pile floats and uses an assembly lifting appliance of the plugging device to realize the loading of the plugging device into the single pile is shown in figure 1, when the plugging device 1 is installed, the single pile 1 is horizontally placed, a lifting rope 3 vertically lifts the plugging device 2 through the assembly lifting appliance 4, and the plugging device 2 is manually horizontally pushed into the single pile 1 to complete the installation of the plugging device 2. Wherein, the appearance of assembly hoist 4 is "7" style of calligraphy, and the middle part of assembly hoist 4 is connected with plugging device 2 through round pin axle 5, and the lower extreme of assembly hoist 4 supports on plugging device 2, prevents that assembly hoist 4 from overturning around round pin axle 5 backward.
