Description

Technical Field

[0001] This utility model relates to the field of bridge erecting machine construction technology, specifically a support system for the lateral movement of a bridge erecting machine. Background Technology

[0002] With the rapid development of the transportation industry, my country's bridge construction has also developed rapidly in recent years, bringing with it many new challenges. In bridge superstructure construction, continuous steel box girders are widely used due to their lightweight, high strength, and aesthetically pleasing appearance, especially on curved sections of newly constructed lines crossing rivers, lakes, seas, existing railway lines, and various types of buildings.

[0003] Currently, for continuous steel box girders on curved sections, the general construction process is "simple support first, then continuous welding hole by hole". This involves dividing the girder into segments and then erecting them. There are two common erection methods: One method is the overall hoisting method, which is characterized by transporting the steel box girder segments as a whole to the bridge site for erection, and then using cranes to lift and erect them in place; the other method is the bridge erection machine method, which is characterized by assembling the bridge erection machine at the bridge site, and then using a crane to lift the girder and move it forward along the main beam of the bridge erection machine to complete the erection.

[0004] The former requires a wide construction site and a large working space, while the latter often faces construction difficulties due to insufficient space on the top of the cap beam when erecting steel box girders on curved sections. Both have their limitations.

[0005] Therefore, those skilled in the art urgently need to design a technical solution to the problem of erecting steel box girders by bridge erecting machines under adverse conditions. Utility Model Content

[0006] In view of the above-mentioned prior art, this utility model proposes a support system for the lateral movement of a bridge erecting machine, which can meet the safety, economy and versatility requirements of most projects using bridge erecting machines for continuous steel box girder erection at this stage.

[0007] This utility model provides a support system for the lateral movement of a bridge erecting machine, comprising: Two supporting foundations are arranged opposite each other along the transverse direction of the bridge, and each supporting foundation includes multiple independent foundations arranged at intervals; Multiple support columns are respectively installed at the upper end of the independent foundation; A support platform, located at the upper end of the plurality of support columns, is used to support the transverse movement track of the middle leg of the bridge erecting machine. The support platform includes a plurality of pile top distribution beams, a plurality of Bailey main beams, and a plurality of small distribution beams arranged sequentially from bottom to top. The plurality of pile top distribution beams are spaced apart along the transverse direction of the bridge, the plurality of Bailey main beams are spaced apart along the longitudinal direction of the bridge, and the plurality of small distribution beams are spaced apart along the transverse direction of the bridge.

[0008] Preferably, the support column is a steel pipe pile, the top of the steel pipe pile is provided with a pile cap, and the bottom of the steel pipe pile is provided with a column foot.

[0009] Preferably, the multiple Bailey beam main beams are fixed by multiple support frames at intervals along the transverse direction of the bridge.

[0010] Preferably, the support platform further includes multiple limiting components, which are disposed at the upper end of the pile top distribution beam and used to fix the Bailey beam main beam.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The support system for the lateral movement of the bridge erecting machine provided by this utility model can enhance the versatility of the bridge erecting machine in erecting beams, reduce the operational risks of the bridge erecting machine in erecting steel box girders, solve the problem of insufficient erection operation space, and greatly improve the safety and quality of production and construction.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] Example: Figure 1-3 The support system shown includes two support foundations arranged opposite each other along the transverse direction of the bridge. Each support foundation includes multiple independent foundations 1 arranged at intervals. Each independent foundation has a support column at its upper end. The support column is made of steel pipe pile 2. The top of the steel pipe pile 2 is provided with a pile cap 3 and the bottom of the steel pipe pile 2 is provided with a column foot 4.

[0018] Furthermore, a support platform is provided at the upper end of multiple steel pipe piles 2 to support the transverse track 5 of the bridge erecting machine's legs. The support platform includes multiple pile top distribution beams 6, multiple Bailey main beams 7, and multiple small distribution beams 8 welded sequentially from bottom to top. The Bailey main beams 7 consist of six Bailey main beams. The multiple pile top distribution beams 6 are spaced apart along the transverse direction of the bridge, the multiple Bailey main beams 7 are spaced apart along the longitudinal direction of the bridge, the multiple small distribution beams 8 are spaced apart along the transverse direction of the bridge, and the multiple Bailey main beams 7 are connected and fixed by multiple support frames 9 spaced apart along the transverse direction of the bridge.

[0019] Furthermore, the support platform also includes multiple limiting components 10, which are disposed at the upper end of the pile top distribution beam 6 and are used to fix the Bailey beam main beam 7.

[0020] This embodiment proposes a support system for the lateral movement of a bridge erecting machine. By replacing the main beam and foundation, it can be made unaffected by construction on land or in water, and is applicable to more spans and types of steel box girders or other box girders, enhancing its versatility. It completes construction with the least amount of steel, improving the economy of steel box girder construction. Furthermore, the support system for the lateral movement of the bridge erecting machine can be reused, reducing construction costs.
