Abstract

The invention discloses a girder transporting vehicle which comprises two carriages, a balance box girder, a girder transporting vehicle main jack and a girder transporting vehicle auxiliary jack. Theinvention further discloses a girder transporting system. The girder transporting system comprises the girder transporting vehicle, a swing mechanism and a rail clamping mechanism. The invention further discloses a steel box girder assembling system which comprises the girder transporting system and a crane system. The invention further discloses a steel box girder assembling method. The method comprises the steps of 1 conveying a steel box girder in place; 2 lowering a lifting appliance to be connected with the steel box girder; 3 lifting the steel box girder, and adjusting the position of the steel box girder three-dimensionally; 4 adjusting the gradient of the steel box girder; 5 assembling the steel box girder; 6 moving a base forwards to the updated assembling end of the steel box girder; and 7 finishing the assembly of the steel box girder. The invention further discloses a steel box girder assembling method. The steel box girder assembling method comprises the steps of A building a supporting frame; B laying a track; C jacking and transporting the steel box girder; D adjusting the three-dimensional space position of the steel box girder and assembling the steel box girder;and E finishing the assembly of the steel box girder. The steel box girder is high in assembly precision.

Description

technical field [0001] The invention belongs to the technical field of steel box girder assembly, and in particular relates to a beam transport vehicle, a beam transport system, a steel box girder assembly system and a steel box girder assembly method. Background technique [0002] The steel box girder transportation and installation technology is to set up a prefabrication field behind the platform along the longitudinal axis of the bridge, prefabricate the girder body in stages, and transport the beams to the designated location section by section by means of the original road, track and hydraulic beam transport vehicle through the beam transport vehicle. Drop beams in place. With the continuous improvement of my country's bridge design and construction technology, a large number of continuous steel box girder bridges have emerged in the fields of highways, urban transportation, and railways. Steel box girder transportation and installation trolleys are widely used in its...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a beam transport vehicle for the deficiencies in the above-mentioned prior art, which has a novel and reasonable design, and solves the transport control and beam section installation accuracy in complex linear situations through three-dimensional six-way transport and installation operations The problem of difficult control improves the accuracy of the force values ​​of the beam body during transportation and installation, prevents damage caused by uneven force on the beam body, and eliminates the horizontal load of the lower structure, ensuring that the beam body is stable during transportation. And the stability during the installation process, using rail transportation, the module car is small in size and large in carrying capacity, and can be used to transport beams on land and above high-altitude supports, which solves the integration of high-altitude beam transport and installation, and is convenient for popularization and use
