Embodiment Construction

[0036] The present invention will be described in detail below in conjunction with accompanying drawing: Figures 1 to 8 As shown, the present invention is composed of a support system 1, a slide rail longitudinal beam system 2, an assembled platform 3, and a traction system 4.

[0037] The support system 1 is composed of a steel pipe pier 11, a tightening device 12, a support frame 13 between columns, an upper beam 14 and a connector 15. The device 12 is surrounded by the pier column 16, and a rubber layer is arranged between the clamping device 12 and the pier column 16; the steel pipe pier 11 and the steel pipe pier 11 are connected by an inter-column support frame 13 to form a whole; the steel pipe pier 11 top An upper crossbeam 14 is provided, on which a slideway longitudinal beam system 2 is placed, and one end of the slideway longitudinal beam system 2 is provided with an assembly platform 3;

[0038] The slideway longitudinal beam system 2 mainly includes double slide...

Abstract

The invention discloses a full-bracket track-bogie bearing and moving device and a construction method for installing steel box girders. The device consists of a bracket system, a slideway longitudinal beam system, a splicing platform and a traction system; steel pipe buttresses in the bracket system are fixed on a treated foundation, the slideway longitudinal beam system is arranged on the bracket system, and mainly comprises two-slideway longitudinal beams, each of the two-slideway longitudinal beams is formed by connecting I-shaped rod pieces in an upper-lower parallel connection method, each side of the slideway longitudinal beam system is provided with one two-slideway longitudinal beam, and two two-slideway longitudinal beams are arranged totally on two sides; and berth bogies on the slideway longitudinal beam system slide on berth bogie tracks on the two-slideway longitudinal beams, and the berth bogies adopt a parallel connection mode and share one electric control switch to realize synchronous starting and closing. The bearing and moving device and the construction method have the beneficial effects that advantages of a large machinery hoisting method and a full-bracket jacking and sliding method are synthesized, the influence on ground traffic is less, the construction speed is fast, the cost is low, and the safety is high.

Description

technical field [0001] The invention belongs to the installation and construction technology of steel box girders in bridge construction projects, and in particular relates to a camel-moving device and a construction method of a full-support rail trolley for installing steel box girders. Background technique [0002] At present, the installation of steel box girders mostly adopts the large-scale mechanical hoisting method or the push-sliding method of the whole support. These two methods have certain limitations in the actual use process. For example, the resources of large-tonnage cranes in the large-scale mechanical hoisting method are relatively scarce, the utilization rate of crane shifts is low and the economy is not good, the requirements for ground roads are too high, and underground pipelines are prone to damage. Destruction; the full-bracket push-slip method has a large difference in the structural stress system between the cantilever working condition of the ja...
