Abstract
The utility model discloses a bridge steel box girder hoisting device under the sea and land intersecting environment. The bridge steel box girder hoisting device comprises a marine bearing platform, a tower arranged on the marine bearing platform, a cable bearing crane, a barge and a track rope. The cable bearing crane is hoisted on the tower through the track rope, the cable bearing crane and the barge are respectively provided with a GPS locating instrument, and the cable bearing crane is formed by a winch, a hoisting cable clamp, a hoisting cable and a hoisting pulley. The winch is arranged at the top of the tower and drives the hoisting pulley through a traction rope, and the hoisting pulley is formed by a fixed pulley assembly, a movable pulley assembly, a steering pulley assembly and a beam. According to the bridge steel box girder hoisting device, the cable bearing mechanism and the barge are respectively provided with the GPS locating instrument, and the cable bearing mechanism and the barge can be accurately positioned, so that hoisting can be performed successfully at one time, and the engineering amount is greatly reduced. The bridge steel box girder hoisting device is simple and reasonable in structure and convenient to popularize and apply.
Description
Technical field
The utility model relates to a kind of steel case beam hanging apparatus, is specifically related to the lifting device for steel box girders of bridge under the staggered environment in a kind of extra large land.
Background technology
Deck unit erection gantry is used for greatly the suspension bridge case beam stage and rises and re-mount, as steel case beam stage or concrete box girder segment.It is supporting point that deck unit erection gantry normally relies on the two root architecture main push-towing ropes that suspension bridge is installed in advance, vertical-lift box girder segment under employing main push-towing rope, and articulate with the hoist cable on main push-towing rope, in the time that this structure lifts for marine steel case beam, because Bridge at Sea height is higher, can cause Hoisting Position inaccuracy, repeatedly lifting, brings unnecessary trouble thus.
Utility model content
Goal of the invention of the present utility model is:
Provide under the staggered environment in a kind of extra large land, can accurately lift lifting device for steel box girders of bridge.
The technical solution of the utility model is:
Design the lifting device for steel box girders of bridge under the staggered environment in a kind of extra large land, comprise Offshore Pile Cap, pylon disposed thereon, deck unit erection gantry, barge, bearer cable, deck unit erection gantry is hung on pylon by bearer cable, on deck unit erection gantry and barge, be equipped with GPS location instrument, deck unit erection gantry is made up of hoist engine, hoist cable cord clip, hoist cable and a hanging pulley, hoist engine is located at tower top, drives lifting coaster by pull rope, plays hanging pulley and forms by determining fly block group and corner block group and crossbeam.
Further, described hoist engine is lifting hoist engine, and its crane capacity is 4800kN.
The beneficial effects of the utility model are:
1) on barge and cable mounted mechanism, be equipped with GPS location instrument, can accurately determine the two position, making is once Liftable success, has greatly saved engineering quantity;
2) the utility model apparatus structure is simple, and structure rationally, easy to utilize.
