Problems solved by technology
After the hoisting radius of the tower crane is exceeded, the transfer is extremely inconvenient; in the construction of a section, the installation, turnover, and unloading of the jack need to be hoisted multiple times. At present, chain hoists are mostly used for jack transfer, which is inefficient, labor-intensive, and time-consuming.

The invention discloses a hanging basket tensioning jack shifting device with suspension pouring girders. The hanging basket tensioning jack shifting device is characterized in that upper oblique rodsin a first triangular lifting frame, a second triangular lifting frame and a third triangular lifting frame are fixedly mounted in U-shaped grooves of first U-shaped lifting lugs and second U-shapedlifting lugs on the lower end surfaces of a first suspension pouring box girder, a second suspension pouring box girder and a third suspension pouring box girder by the aid of first hinge pins and second hinge pins, and the first suspension pouring box girder, the second suspension pouring box girder and the third suspension pouring box girder are structurally identical to one another; a first trolley, a second trolley and a third trolley which are structurally identical to one another are arranged on a first running track, a second running track and a third running track; first limiting stoppers are welded at two ends of the first running track; another second running track is fixedly mounted with the bottom surfaces of the first trolley, the second trolley and the third trolley; rollersin a fourth trolley transmission device are arranged on the other second running track, and an electric hoist is mounted on a fourth trolley, so that the hanging basket tensioning jack shifting devicewith the suspension pouring girders can be formed.
Description
Technical field [0001] The invention relates to a tension jack hoisting device for continuous beam hanging basket cantilever construction, in particular to a suspension beam hanging basket tension jack moving device. Background technique [0002] With the rapid development of my country's passenger dedicated lines and high-speed railways, large-span prestressed box girder viaducts have been widely used. The prestressed concrete structure effectively improves the stiffness and crack resistance of the bridge components, reduces the weight of the structure, increases the bridge span, and increases the durability of the structure. After the pouring of each section of the cantilever construction is completed, the longitudinal prestress must be tensioned. The tension of the prestressed steel strand is a key process of the bridge engineering, and the tension jack is the main equipment for prestressing. The tonnage jack is heavy and the installation location is narrow. After the tower ...
