Abstract

The invention discloses a pre-compensation method measuring and positioning technology for a steel pile trolley track. The technology is characterized by comprising trolley track tolerance decomposition, steel pile trolley track segmented manufacturing and steel pile trolley track field machining, wherein the steel pile trolley track segmented manufacturing comprises the steps of allowance addingand node form arrangement, manufacturing of a segment of an upper track of a side guide track, manufacturing of segments of a lower track of the side guide track, and manufacturing of segments of walking tracks; and the steel pile trolley track field machining comprises track machining condition preparation and machining preparation. The pre-compensation method measuring and positioning technologyfor the steel pile trolley track has the advantages that the structural strength and the positioning precision of key parts are ensured at the expense of a micro reduction of the weight of a ship body, thus a series of problems such as insufficient machining amount, insufficient strength and insufficient machining precision caused by field structure manufacturing deviation in the later period aresolved, and the technology has outstanding advantages technically.

Description

technical field [0001] The invention relates to the technical field of construction methods for modern ships and marine engineering structures, in particular to a steel pile trolley track pre-compensation method for measurement and positioning technology. Background technique [0002] 5000KW cutter power self-propelled cutter-suction dredger is a self-propelled cutter-suction dredger with double propellers, double-rotating nozzles, and full electric drive. It is the third largest cutter-suction dredger in the world and the first in Asia. , the design and construction of the ship has filled in the gaps in the field of dredging in our country. [0003] The ship's steel pile positioning device mainly includes: main steel pile, auxiliary steel pile, main steel pile trolley, auxiliary steel pile trolley and other components. walk. [0004] However, the steel pile trolley has high precision requirements, and the positioning of its track is not a small difficulty. Therefore, in ...
