Description
Technical field:
The present invention relates to the secondary positioner of a kind of boats and ships stern complete cross section in dock, be used for boats and ships, belong to the marine technology field in the displacement location of fitting process boats and ships stern complete cross section in dock.
Background technology:
Along with the maximization of ship building, at present increasing shipbuilding enterprise builds Large Ship Dock, adopts the dock shipbuilding.Dock the time considers that in design shipyard can fertile maximum boats and ships, determine the size dimension of dock, but shipyard possibility most of the time institute's shipbuilding oceangoing ship yardstick is much smaller than the yardstick of dock in the reality, utilization ratio and the production efficiency of whole shipyard, mostly the employing series connection shipbuilding mode of shipyard in order to improve dock.After the ship of promptly making in advance undocked, the afterbody complete cross section of next bar ship of having made need be shifted again, locate, and carries out the production of next production cycle.
Boats and ships are the installation tram of determining each segmentation of boats and ships by various position lines, check line in fitting process, as center check line, reference line for frame etc., these check lines are inscribed on the line of centers channel-section steel of dock bottom, and perhaps on the wing wall, this is the basis that guarantees the correct assembling of boats and ships subsequent segment.So boats and ships stern complete cross section must guarantee that when reorientating the hull line of centers drops on the line of centers channel-section steel of dock bottom, also aliging substantially with former rib position in position, rib position, so just is convenient to the assembling of subsequent segment.Patent (US 4227828) has been introduced a kind of hull shift assembly, and this device is formed by being installed in the several rows of roller of dock bottom, and hull displacement is to drag hull by draw gear to roll on roller and move on to the relevant position.This hull shift assembly complex structure, cost is higher.
Summary of the invention:
The objective of the invention is at actual demand and the deficiencies in the prior art, design provides the secondary positioner of a cover boats and ships stern complete cross section in dock, satisfies the displacement positioning requirements of boats and ships stern complete cross section in dock.
In order to realize such purpose, in the technical scheme of the present invention, adopt the method for fixed point back alignment earlier, in the front and back of boats and ships stern complete cross section two registration devices are set: stem registration device and afterbody registration device, the afterbody registration device adopts the fit form of the female androtype of the frustum of a cone, the form that the stem registration device adopts wedge shape terrace with edge and the female androtype of webge slot to cooperatively interact.
During boats and ships stern complete cross section location, registration device must can both guarantee the accurate location of complete cross section in longitudinal and transverse two directions, therefore device must satisfy the stern complete cross section in the process that descends, and can aim at center of location automatically, and can ajust the position of center line of stern complete cross section automatically.Because the stern complete cross section has trim and have length and the skew of Width in position fixing process, so the present invention adopts the method for fixed point back alignment earlier, and two registration devices are set in the front and back of stern complete cross section.Registration device near tail end contacts because of elder generation, adopt the form of the male and female frustum of a cone, the part that is fixed on the stern complete cross section is the male frustum of a cone, be fixed on the female frustum of a cone that is of dock bottom, in the sinking process behind stern complete cross section coarse positioning, two frustums of a cone cooperatively interact, and just can accurately determine the position of a bit.For registration device near head end, its part that is fixed on the stern complete cross section is a wedge shape truncated rectangular pyramids, the part that is fixed on the dock bottom is a rotating webge slot, when wedge shape terrace with edge and webge slot cooperatively interact, just can determine straight line, this straight line must be by the close determined line of centers of afterbody registration device.Adopt above-mentioned two registration devices, can realize the self-orientation of stern complete cross section in the sinking process, and avoided stern complete cross section and dock bottom in position fixing process, to bear huge bending moment and the moment of torsion that produces because of the location, its accuracy of positioning only depends on the setting accuracy of two registration devices.
The present invention has significant effect and good prospects for application.The competition of shipbuilding industry at present is more and more fierce, the more and more large-scale change of institute's shipbuilding oceangoing ship, and many in the world large-scale shipyards all or have just prepared to build Large Ship Dock, and shorten shipbuilding period by every means, enhance productivity.For the Large Ship Dock shipbuilding, adopting tandem shipbuilding method is to raise the efficiency, shorten one of best approach of shipbuilding period.Adopt dock series connection shipbuilding to certainly exist the displacement and the second positioning problem of series connection complete cross section.The present invention has adapted to the dynamic and market outlook of present shipbuilding industry development, and expectation will have good application prospects.

Design of the present invention considers, after boats and ships stern complete cross section location, to remove position fixing system and shift out hull bottom, so also must consideration during the Design Orientation system after device is removed, still have enough height to take out registration device together with base.In order to address this problem, adopt below base, to add a pedestal and cushion block, in position fixing process, the power on the base is passed to headblock below pedestal and the base by cushion block, passes to the dock bottom by pedestal and headblock again.When removing registration device, prop base with jack, remove cushion block and headblock on the pedestal then, jack shrinks, and registration device and base fall together, just can shift out registration device by some other auxiliary facilities.
Boats and ships stern complete cross section is when the location, and safety of ship drops on the block of laying the dock bottom when requiring correct the location.When but the dock bottom block falls thereon at ship weight fully, compressive deformation can take place.Position fixing system must descend along with the contraction of block when therefore locating, otherwise the huge external force that is caused by hull weight can be born in the hull part of registration device and mounting and positioning device, thereby causes the local failure of hull.The stern complete cross section bumps when beginning to contact when the location in addition, because the huge quality of hull, therefore the impulse force that produces is quite big, the destruction that may cause dock bottom or hull.In order to address these problems, spring has been installed in the inside of registration device.
The present invention is reasonable in design, and the location accurately is suitable for the displacement location of any buoyancy aid.
