Description
Technical field
The present invention relates to shipbuilding technical field, particularly in a kind of ship building process in dock floating and secondary falling pier registration device.
Background technology
For improving dock degree of utilization, serial boats and ships tend to adopt two line mid-series construction methods in manufacture process.For the shipyard of undertaking the construction of more ship type, different depressed place phase boats and ships also there will be half ship to build in manufacture process.Because production cycle is different, the boats and ships that construction completes will first undock, the boats and ships of not yet having built will first float, then the pier that falls continues to build, these all need to control it and move ship positionning precision and sit pier precision under hull floating condition, after making it sit pier, meet the accuracy requirement of seat pier, or satisfied half ship closes up construction precision requirement.
Traditional ship's method of moving adopts vertical type winch capstan, winch to pull by the steel rope being arranged symmetrically with on boats and ships both sides, and this method exists following shortcoming when dry-docking shipbuilding:
When 1, traditional vertical capstan winch, winch are located, inertia is larger, wayward precision.And because depressed place is wide, hull one side from wing wall away from, steel rope is refuted and is connect longlyer, safety factor is low.
2, as shown in Figure 1, while also having other boats and ships in depressed place, particularly side by side time, during location, easily produce interference; When in depressed place, two lines carry side by side, when adopting original four cable Eight characters location, when locating simultaneously, two ships there will be four hawsers by territory, middle pleural area, depressed place to interfere with each other, or hawser and side by side hull structure/equipment/fitting-out collide, and half and half ship port and starboard cable length is extremely asymmetric, double ship adjustment and positioning precision are totally unfavorable, and positioning precision is difficult to guarantee.
And in the depressed place that patent 200410066741.6 and patent 200810039748.7 are announced, the registration device of floating and secondary falling pier method is fixed type, and floating and Luo Dun substantially in situ, for two and half ships, carry under water, 50,000 tons of semi-submerged ships such as our company's construction, two and half ships are built at diverse location, in dock after floating, by dragging location, again the pier that falls closes up lift-launch, above-mentioned patented method significant discomfort is used, in " naval vessel is floating and secondary falling pier positioning accurate control method in dock " that patent 200810039748.7 is announced, registration device need be according to hull lines fabrication and installation, there is no general applicability, and in above-mentioned two patented methods, the dismounting of registration device also needs to spend man-hour, so a kind of application is extensive, and the registration device of easy accessibility is more aobvious advantage.
