Description

TECHNICAL FIELD

[0001] The present application relates to the field of ship launching technology, more particularly, it relates to a method for launching a super-long ship by transverse movement. BACKGROUND

[0002] In the process of building small and medium-sized ships, the mechanical longitudinal launching mode is as follows: after the ship is built on the land berth, the ship is moved from the berth to the transverse moving track (or transverse moving car), the ship is moved transversely by the transverse moving track, and then the ship is launched along the launching ramp with a certain slope after being aligned with the launching ramp.

[0003] When the weight and length of the ship to be built are within the load range of the transverse moving track, the safety of the transverse movement process is guaranteed. However, when the length of the ship to be built exceeds the length of the transverse moving track by a large margin, such as 90% of the length of the transverse moving track, that is, the length of the transverse moving track is 50 meters, and the length of the ship to be built is 95 meters, the length of the overhanging part is 45 meters, and the weight of the overhanging part will cause a large overturning moment if there is no support, and the weight center position will cause a large overturning moment, which will cause deformation, overload and even longitudinal inclination of the end of the transverse moving track, the end of the transverse moving track, and the ship structure near the end of the transverse moving track. The usual way is to carry out technical transformation and lengthen the transverse moving track, but it involves huge investment in equipment, infrastructure, land and funds, and the continuity of production will be interrupted, and the cost is too high, sometimes the order has to be abandoned.

[0004] In the prior application of the applicant, the patent technology with the publication number CN102730169B discloses a ship launching transverse movement auxiliary device, which comprises a ship lifting trolley and a trolley track, the ship lifting trolley is arranged on the trolley track, the ship lifting trolley is provided with a ship moving track, one end of the ship moving track is a river side near the river side A, and the ship moving track further comprises an auxiliary transverse moving track, a separable movable track frame and a transverse moving trolley, the separable movable track frame is arranged beside the near river side A of the ship moving track, the auxiliary transverse moving track is installed on the top of the separable movable track frame, and the transverse moving trolley is arranged on the auxiliary transverse moving track. The present application has the advantages of fast construction period, small labor intensity, saving of manpower and material resources, good practicability and safety, convenient disassembly, maintenance and use, and can effectively improve the launching capacity of the shipyard, and the length of the launched ship can be increased by 30 meters.

[0005] The existing ship launching transverse movement auxiliary device can move the super-long ship to the launching ramp, but in the actual transverse movement process, the transverse movement is finally aimed at aligning with the launching ramp with a slope, and the stern gradually descends along the slope, so the ship body is prone to transverse inclination.

[0006] Therefore, it is urgent to develop and design a method for launching a super-long ship by transverse movement to solve the above technical problems. SUMMARY
