Hanging bracket for integral hoisting of ship superstructure and hoisting
Technical field
The present invention relates to a kind of hanging bracket for integral hoisting of ship superstructure and hoisting, it belongs to boats and ships and ocean structure manufacturing and manufacturing process field.
Background technology
Bracket for integral hoisting of ship superstructure is an advanced technologies in the ship building, raising along with pre outfitting degree before the superstructure lifting, integral hoisting can enlarge superstructure undoubtedly install to the ship before on land scope of work, improve labor productivity, shorten ship building period, reduce the shipbuilding cost.But owing to be subjected to the restriction of shipyard equipment, place and hoisting Design level, it is little still to be confined to yardstick, the scope that superstructure rigidity is stronger.
But boats and ships maximize and the raising of pre outfitting level makes size, the weight of the whole segmentation of superstructure increasing, and rigidity reduces relatively.Meanwhile, the superstructure thickness of slab is also developing to the thin plate direction, and advanced shipyard has brought into use the 4.5mm steel plate to build ship superstructure.This shows, when lifting and mounting complete superstructure, control its distortion in order to avoid the impaired difficulty more that becomes of pre outfitting.Reasonably auxiliary lifting tooling device of research and hoisting are the keys of smooth implementation superstructure lifting.
Summary of the invention
In order to control its distortion in order to avoid pre outfitting is impaired when the bracket for integral hoisting of ship superstructure, the present invention should design a kind of hanging bracket for integral hoisting of ship superstructure and hoisting, this suspension bracket adopts the general frame structure, its top links to each other with hoist lifting hook, the below then provides a large amount of hoisting point positions, be used for guaranteeing that superstructure is evenly stressed, reach the purpose of effective proof stress and distortion; It is big that suspension bracket has the rigidity of structure, and from heavy and light, the lifting distortion is little, is applicable to different boats and ships, repeatedly used characteristics; The hoisting that is adopted is simple, practical.
The technical solution adopted for the present invention to solve the technical problems is: a kind of hanging bracket for integral hoisting of ship superstructure, the framed structure that described suspension bracket is made up of transverse member and longitudinal; The I-shaped cross-section beam that transverse member is made up of first top panel, first riser and first lower faceplate is provided with one in the bottom of first riser near the first lower faceplate place and ranked first lifting hole(eyelet); The I-shaped cross-section beam that longitudinal is made up of second top panel, second riser and second lower faceplate is provided with one in the bottom of second riser near the second lower faceplate place and ranked second lifting hole(eyelet); Intersection at first top panel and second top panel is provided with hanger.
Described transverse member is 2~10; Described longitudinal is 2~10; Described hanger is along 2 transverse member settings.
A kind of hoisting that uses hanging bracket for integral hoisting of ship superstructure:
A, first cable wire are connected with hanger on the suspension bracket through hook, and crane is through first cable wire suspension bracket of slinging;
B, the upper end of second cable wire is connected first lifting hole(eyelet) and second lifting hole(eyelet) through upper lift ring by the design-calculated suspension centre, the lower end connecting bolt tensioner of second cable wire, the lower end of spiral tensioner connects the 3rd cable wire;
C, the 3rd cable wire connect the hanger that ship superstructure pushes up through lower lift ring;
D, the crane suspension bracket of slowly slinging allows second cable wire and the 3rd cable wire tensioning, and it is stressed evenly by the cable wire of each suspension centre to rotate the spiral tensioner;
E, crane are slowly sling ship superstructure to the installation site through suspension bracket.
The invention has the beneficial effects as follows: this hanging bracket for integral hoisting of ship superstructure adopts the general frame structure, and transverse member and longitudinal all adopt the I-shaped cross-section beam of being made up of panel, riser and lower faceplate, and good rigidly is in light weight; Bottom at riser is provided with row's lifting hole(eyelet) near the lower faceplate place, can press the optimal design suspension centre easily and install.This suspension bracket can satisfy different boats and ships to be used, and suspension bracket and ship superstructure are easy to connect, and hoisting is simple, does not need to change the superstructure structure and can realize integral hoisting, and effectively control lifting distortion significantly improves process safety; Suspension bracket is the effective guarantee that realizes all kinds of bracket for integral hoisting of ship superstructure technologies; And lifting and mounting complete superstructure will enlarge superstructure make on land scope of work, improve labor productivity, shorten ship building period, reduce the shipbuilding cost.
