Embodiment Construction

[0050] The core of the present invention is to provide a jacking mechanism, which has multi-stage jacking units, and can achieve the purpose of increasing the lift under the action of a small driving force. Another core of the present invention is to provide an offshore wind turbine transportation and installation platform with the above-mentioned jacking mechanism.

[0051] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The jacking mechanism in each embodiment herein is placed in the offshore wind turbine transportation and installation platform, and is used to lift the wind turbine holding mechanism. In fact, the jacking mechanism in each embodiment can also be used to lift other structural parts.

[0052] Please refer to Figure 2 to Figure 4 , figure 2 It is a structural...

Abstract

The invention discloses a jacking mechanism, which is characterized in that the jacking mechanism comprises at least two jacking unit groups and at least three force transfer components distributed along the height direction, and each jacking unit group comprises at least two jacking units; each jacking unit is provided with an upper connecting rod and a lower connecting rod which are hinged together at one end, the jacking units are sequentially arranged between adjacent force transfer components, and the upper ends of the upper connecting rods and the lower ends of the lower connecting rods are respectively hinged between adjacent force transfer components; the jacking mechanism additionally comprises a thrust device which drives the jacking units to be reset or stretched straight; and hinge shafts are arranged in parallel. Compared with the prior art, since the jacking mechanism provided by the invention is a multistage jacking mechanism, by orderly connecting the jacking units among the force transfer components to increase the lift of the jacking mechanism stage by stage to the sum of the lifts of all jacking units, the overall lift of the jacking mechanism is improved. The invention additionally discloses an offshore fan transportation and installation platform.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a jacking mechanism. The invention also relates to an offshore wind turbine transportation and installation platform. Background technique [0002] The jacking mechanism has certain applications in the technical field of construction machinery. Take the offshore wind turbine transportation and installation platform as an example. [0003] There are two main installation methods for offshore wind turbines: separate installation and integral installation, and the integral installation is further divided into hoisting and lifting. [0004] Please refer to figure 1 , figure 1 It is a structural schematic diagram of the offshore wind turbine transportation and installation platform, which shows the lifting mechanism used to hold and lift the wind turbine. [0005] The patent application with application number 201010519989.9 discloses a wind turbine holding and lift...
