TECHNICAL FIELD

[0001] The utility model belongs to steel pipe pile preparation technical field, and specifically relates to a jacking adjusting device for wind power steel pipe pile group. BACKGROUND

[0002] With the increasing capacity of offshore wind turbines, the diameter of the cylinder of the steel pipe pile in the foundation structure is getting larger and larger, and the wall thickness and weight are also getting larger and larger. Correspondingly, the weight of each segment in the workshop manufacturing process is also getting heavier, and in the workshop group process, the position of the roller frame needs to be moved and the height of the roller frame needs to be adjusted to adjust the relative height. However, with the increasing weight of the segment, the jacking capacity of the roller frame itself cannot meet the requirements, so external force is needed to adjust the relative height of the group position.

[0003] The commonly used method is to use two cranes for adjustment, but the workshop production task is busy, and if the crane is needed in the group engineering, waiting is needed, and if two more cranes are added, the cost will increase substantially.
