Description

The marine special-purpose crane ship of setting a roof beam in place of transporting
Technical field the utility model relates to a kind of crane ship that the prefabricated or part that pieces together in advance of large bridge is installed that is used for transporting and set up at sea.
Background technology is along with China's rapid economic development, and the coastal economy developed regions will be put many marine bridges into operation, and general construction method is, and the one, sections is prefabricated at fabrication yard, implements section assembling at the bridge location place with the bridge formation machine.Set up marine bridge in this way and have the problem of following two aspects: 1, sections splicing seams at sea under the environment, its corrosion stability, endurance issues are outstanding; 2, prefabricated subsection is many, and the assembling construction cycle is long, and is poor to changeable marine meteorology and hydrological environment adaptive capacity.Another kind is to utilize the whole hole of bridge formation machine to set up, because marine bridge span is bigger, 50~70 meters prestress box beams are put in order 1300~2000 tons of Kong Chongyue, make bridge formation machine structure huge, and heavy beam transports very difficult on bridge floor.
The summary of the invention the purpose of this utility model is at above-mentioned present situation, aims to provide a kind of fortune, frame unification, and at sea the special-purpose crane ship of setting a roof beam in place is transported at the construction sea that adaptive capacity is strong, operating efficiency is high under the condition.
The implementation of the utility model purpose is that the marine special-purpose crane ship of setting a roof beam in place of transporting comprises hull, hoisting crane, anchoring system, control system.The catamaran of hull 1 for connecting together with torsion box 3.Hoist frame 4 is installed on the torsion box, hoist frame be positioned at make the hoisting crane suspension centre be centered close to the hull centre of buoyancy near.Crane hoisting system 7 is made up of fixed pulley group, steel rope and the running block on the top that is positioned on hoist frame, and running block is installed on the hanging beam shoulder pole 6.The outer topside of catamaran two lamellar bodies is useful on the colligation carriage 2 of confined concrete precast beam displacement.Hoisting winding 10 is installed on the torsion box, anchor capstan 9 is installed on the deck.
This ship is catamaran (seeing Fig. 1,2), is connected by torsion box 3 to stern in the ship of two lamellar bodies, has solved the moment of torsion of catamaran when navigation.Torsion box adopts the transversum form, make the sheet physical efficiency bear the transverse bending moment of lamellar body better, and when hull is opened the shelves variation, can not change under the preceding topic of version, by changing torsion box length, make two lamellar bodies open shelves can between 5m-18m, change, increased comformability to different engineerings.Adopt this structure, not only can adapt to setting up of single supported beam and double cantilever beam, also can be used for lifting simultaneously bridge heavy stand member and prefabricated pier shaft etc. are installed.Because catamaran molded breadth broad, Stability of Ship is good, and capacity of anti-storm is strong, and the ability that adapts to marine environment is strong.Hoist frame is positioned on the connecting bridge, adopts the center lifting method.Adopt this kind lifting method, the suspension centre center arrangement is near the hull centre of buoyancy, during the crane loading operation, make hull remain the state of top-uping, the installation contraposition operation and the construction safety that help the heavy bridge beam also can make full use of and send out by the hull structure ability, embody the characteristics of Technological Economy.
In the utility model when work,, ship is got beam from harbour, and beams of concrete 5 liftings that need are set up also link to each other with colligation carriage 2, and after navigation was transported to the position of building bridge, hoist winch 10 of unlatching was sling beams of concrete, places and sets up the position.
The utility model adopts full-rotating rudder with propelling unit, equips first thruster.Can realize that the hull level is traversing, cast function, concrete very strong dynamic positioning ability.The utility model construction is simple and direct, the operating efficiency height, and biggest lifting capacity 2500t, maximum height of lift 41m (waterline is apart from top surface of the beam) is strong to the marine environment adaptive capacity.

Specific embodiment the utility model is made of hull, hoisting crane, boat starting, anchoring system, control mechanism etc.
The main structure of hoist frame adopts the truss form (seeing Fig. 4,5) of sealing box-shaped rod member, the column 19 of hoist frame 4 has strut 14 supports on back lower supporting rod 18, back stay 15, the back, longeron 12, entablatrance 21, center member 22, front strut 20 are arranged at its top, and each parts is formed a sealing box type rod piece form.A heavy lift of hoist frame and weight own are imported on the crane ships by torsion box 3 by principal post, back stay, diagonal brace 23.The main part of hoist frame adopts 14MnNbq High-Strength Low-Alloy structural steel, and the thickness of slab of main structure is not less than 8mm, can satisfy the load-bearing requirement.
Be the requirement that the adaptation hoisting crane sets up 70m and 60m prestressed concrete beam, ad hoc hanging beam shoulder pole 6 (see figure 1)s of having counted of the utility model, the hanging beam shoulder pole is used to lift by crane prefabricated components (as beams of concrete, pier shaft etc.).The hanging beam shoulder pole is a truss form, is made up of two main trusses 24 and connection structure.Hanging beam shoulder pole both sides have hangs two of beams of concrete 5 and hangs contact 26,27.The hanging beam shoulder pole is driven by hoist frame winch 10, steel rope and assembly pulley 7.According to the movable pulley of assembly pulley height difference of living in, the hanging beam shoulder pole has different suspension centres with respect to 70m, 60m place.
