Embodiment Construction

[0048] The core of the present invention is to provide a luffing device installed on the offshore fan transportation and installation platform. When the fan is transported and installed, the luffing device can keep the fan in a vertical state all the time without the auxiliary pulling of other ships. High performance, can improve construction efficiency. Another core of the present invention is to provide an offshore wind turbine transportation and installation platform including the above-mentioned luffing device.

[0049] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. For ease of understanding, the luffing device is described in conjunction with the offshore wind turbine transportation and installation platform.

[0050] Please refer to Figure 1 to Figure 4 , figure 1 It...

Abstract

The invention discloses an amplitude variation device, which is arranged on a platform for transporting and mounting an offshore wind turbine and comprises an active amplitude variation mechanism, wherein the active amplitude variation mechanism is provided with a horizontal support platform, a horizontal cross beam, a first stay bar and a second stay bar; the horizontal cross beam is positioned above the horizontal support platform and is used for vertically fixing a fan; the first stay bar and the second stay bar are arranged between the horizontal support platform and the horizontal cross beam and are arranged in parallel; the horizontal cross beam and the horizontal support platform are arranged in parallel; two ends of the first stay bar and the second stay bar are respectively hinged to the horizontal cross beam and the horizontal support platform; various hinge shafts are arranged in parallel; and the amplitude variation device also comprises an amplitude variation driving device for driving the first stay bar and the second stay bar to swing in the same plane. The active amplitude variation mechanism of the amplitude variation device is in a parallelogram mechanism; duringamplitude variation, the horizontal cross beam is always positioned in a horizontal state; the fan which is vertically positioned with the horizontal cross beam can be always positioned in a verticalstate; and stable hoisting and transferring and accurate mounting of the fan can be finished without assisted work of other engineering ships. The invention also discloses the platform for transporting and mounting the offshore wind turbine, which is provided with the amplitude variation device.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a luffing device used for installing offshore wind turbines. The invention also relates to an offshore wind turbine transportation and installation platform. Background technique [0002] Offshore wind power generation technology is to build a wind farm in a suitable sea area, install wind generators (hereinafter referred to as wind turbines) on the basis of the wind turbines in the wind farm, and convert wind energy into electrical energy through the wind turbines. [0003] A fan generally includes a fan tower, a nacelle and an impeller. A generator and a gear box are installed in the nacelle, the main shaft of the gear box protrudes from the outside of the nacelle, and the impeller is installed on the main shaft. The bottom end of the fan tower is provided with a flange for connecting with the fan foundation, and the nacelle is installed on the top of the fan to...
