Description

Technical Field

[0001] The present application relates to the field of bridge engineering technology, and in particular to a system for the overall transportation and installation of a steel cap beam. Background Art

[0002] Traditional steel cap beams are often installed by horizontal jacking, longitudinal sliding, or bracket method of segmented lifting. This requires the erection of a large number of steel pipe brackets, a larger site, a large amount of materials, and a long construction time. In addition, due to the heavy weight of the steel cap beam, traditional lifting construction requires a larger crane, which has high requirements for the bearing capacity of the foundation. If the construction site is a soft foundation or a low-grade bridge, the conditions for lifting construction are not met. In addition, due to the heavy weight and large size of the steel cap beam, its transportation also poses a major problem. It has high requirements for the bearing capacity of the road surface. The traditional method of transportation is to use conventional flatbed trucks, but the steering of the flatbed trucks is relatively rigid and not flexible enough, making transportation on the road very troublesome. It is also difficult for conventional flatbed trucks to adjust the lifting direction and angle in the lifting site.

[0003] In view of the above problems, the present invention provides a new technical solution. Utility Model Content

The steel cap beam is straddled on the camel beam brackets of the two mobile trolleys, and the three-way jack can act on the camel beam bracket and shift the camel beam bracket in three directions.

[0006] According to an embodiment of the present invention, a system for transporting and installing an integral steel cap beam is provided, wherein the movable vehicle is a self-propelled modular flatbed vehicle.

[0007] According to an embodiment of the present invention, a steel cap beam integral transportation and installation system is provided, wherein the mobile trolley includes a load-bearing carriage, a plurality of sets of running wheels are provided below the load-bearing carriage, and a power motor is provided on the load-bearing carriage.

[0008] According to an embodiment of the utility model, a system for transporting and installing an integral steel cap beam is provided on the camel beam bracket, and the steel cap beam and the camel beam bracket are connected via the ball head connector.
