Technical Field
The invention relates to the field of engineering equipment, in particular to a lifting device.
Background
In the fields of offshore large-scale wind power installation, petroleum and natural gas and the like, the self-elevating platform is widely used, and pile legs of the self-elevating platform are lifted by hydraulic pressure to perform operations such as self-elevating platform installation.
Generally, when a self-elevating platform pile leg is lifted, a fixed ring is connected with the platform, a movable ring is connected with the pile leg through a bolt, and the movable ring and the fixed ring are connected through a hydraulic cylinder. And (3) extending the hydraulic cylinder, lowering the pile leg or pressing the pile, pulling out the bolt after the hydraulic cylinder is in place, retracting the hydraulic cylinder, connecting the hydraulic cylinder with the pile leg by using the bolt, extending the hydraulic cylinder, and lowering the pile leg or pressing the pile. The pile legs or the piles can be lowered to complete the positioning of the self-elevating platform; otherwise, the pile leg can be pulled out to be in place at other places.
In the working process, the retraction and the pin pulling time of the hydraulic cylinder are not effective working time, so the efficiency is low.

one end of the second hydraulic cylinder is connected with the fixed ring, and the other end of the second hydraulic cylinder is connected with the second movable ring.
The stationary ring comprises:
a stationary ring substrate;
a fixed ring first hydraulic cylinder support;
a second fixed-ring hydraulic cylinder support;
and (5) fixing ring working support.
