Abstract

The invention relates to the field of bridge construction, and provides a long-distance steel box girder dragging system crossing an existing line. Dragging construction equipment comprises a supporting device, a dragging device and a deviation rectifying device. The supporting device comprises a rolling device; the dragging device comprises a first steel wire rope fixed pulley assembly, a movablepulley assembly and a first winding device; the deviation rectifying device comprises an installation support and a second winding device. The installation support comprises two support bodies, fixedpulleys are arranged on the support bodies, a second steel wire rope is wound on the second winding device, and a connecting piece used for being connected with the steel box girder is arranged at the end of the second steel wire rope. The steel box girder is supported by the rolling device; sliding friction is converted into rolling friction, the friction force of the contact position is reduced, so that the power of the dragging device is reduced and the service life of each component is prolonged; the position of the steel box girder is adjusted through the deviation rectifying device, thesteel box girder moves in the designed direction, so that the matching difficulty between the steel box girder and the supporting device is reduced, and construction is smoothly conducted.

Description

technical field [0001] The invention relates to the field of bridge construction, in particular to a long-distance steel box girder dragging system across existing lines. Background technique [0002] While the scale of the city is constantly expanding to accommodate the increase in the urban population, the first thing to bear the brunt is the construction of municipal roads. In order to strive for the best road traffic plan to adapt to the development of the city, it will inevitably conflict with the existing ground buildings. To ensure the safety of municipal road construction, it is also necessary to properly address the impact of road construction on high-speed railways. [0003] The steel box girder dragging method construction is to assemble the steel box girder on the embankment at the bridge head or on the scaffold, and set up a slideway on the steel box girder, and set up a slideway on the embankment or scaffolding, and pass through the roller between the upper an...
