Technical Field

[0001] This invention relates to the field of engineering machinery technology, and in particular to a self-climbing connection device and a crane. Background Technology

[0002] During the installation of certain equipment, some components need to be installed at high positions. To facilitate installation, self-climbing connection devices are used to assist in the installation of these components. For example, during the installation of wind turbines, a crane carrying the wind turbine can climb along the tower using the wind turbine tower as a foundation, thus achieving the purpose of hoisting the wind turbine and reducing installation costs.

[0003] During the self-climbing process, due to the influence of the component's own weight and external interference, there is often a need to adjust the position, such as adjusting the positional relationship between the crane and the tower, or adjusting the position of the component itself.

[0004] However, the existing self-climbing connection device technology only provides the function of switching between fixed connection and disconnection between the crane and the tower, and cannot realize the function of adjusting the position of the two. As a result, if the crane and the tower cannot be fixedly connected due to position displacement during actual self-climbing application, a large safety risk will be generated.
