Method for assembling large crane bearing and ship body

The invention provides a method for assembling a large crane bearing and a ship body, and relates to the field of crane bearings and ship bodies. The assembling method based on the large crane bearing and the ship body comprises the steps that S1, size and precision measurement is conducted on the mounting positions of the crane bearing and the ship body, and it is ensured that a precise measuring tool meets the preset standard; a precise measuring tool and a high-precision laser alignment system are used, the assembly precision is ensured, faults caused by inaccurate alignment are reduced, the consistency and correctness of bolt tightening are ensured by using an electronic torque wrench, the assembly reliability is further enhanced, the assembly efficiency is remarkably improved through robot auxiliary assembly and automatic cleaning equipment, and the production cost is reduced. The investment of human resources is reduced, the monitoring and adjusting speed in the assembling process is accelerated through
