Description

Technical Field

[0001] This utility model belongs to the field of construction engineering lifting and hoisting technology, and in particular relates to a track foundation device for a cross-river ultra-large gauge elevated gantry crane. Background Technology

[0002] Gantry cranes are a type of lifting equipment characterized by high site utilization, large operating range, wide adaptability, and strong versatility, and are widely used in land bridges and prefabrication plants. The gantry crane track foundation is a crucial support for the safe and stable movement of the crane. Traditionally, the gantry crane track foundation structure is a rectangular reinforced concrete strip foundation, set on a leveled or backfilled site. The traditional construction process is roughly as follows: site leveling or backfilling → foundation trench excavation → bottom compaction → subgrade concrete construction → rebar tying → formwork construction → embedded part installation and positioning → concrete pouring and curing.

[0003] The conventional construction methods for steel structure bridges spanning rivers are incremental launching or floating crane installation. Incremental launching is unsuitable for multi-span variable-height beams, curved beams with varying curvature, or bridges with large vertical curvature. Incremental launching is uneconomical for bridges with spans greater than 80m. The repeated stress during the launching process leads to larger beam heights, more temporary tensioning, and cumbersome tensioning procedures. Construction progress slows down as bridge length increases. Floating crane installation is unsuitable for bridges with shallow water levels. Floating crane installation requires high levels of technical expertise and operational experience, has high mechanical costs, and is significantly affected by wind, waves, and currents, posing significant safety risks. Conventional construction methods for installing long-span steel structure bridges spanning rivers often suffer from high construction costs, low efficiency, difficulty in guaranteeing accuracy, and high safety risks. Using gantry cranes for steel structure assembly on land is a simple and efficient construction method; however, gantry cranes are rarely used in the installation of steel structure bridges spanning rivers, and the track foundation of gantry cranes installed across rivers is of paramount importance. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a simple, convenient, and reusable track foundation device for a cross-river ultra-large gauge elevated gantry crane. It can be set up in water, enabling a land-based gantry crane to be set up in the air across the river. The elevated gantry crane is used for the installation of cross-river steel structure bridges, reducing the construction period of cross-river steel structure bridges, saving construction costs, reducing the risks of high-altitude operations, and reducing water pollution.

[0005] The purpose of this utility model is achieved through the following technical solution: A track foundation device for a cross-river ultra-large gauge elevated gantry crane includes a steel pipe pile foundation, a Bailey beam foundation, and a rail foundation. The steel pipe pile foundation is set along the cross-river direction and fixed to the riverbed using a fishing method. A double-I-beam crossbeam is fixed to the upper end of the steel pipe pile foundation. The Bailey beam foundation is fixed to the double-I-beam crossbeam and is aligned with the direction of the steel pipe pile foundation. A transverse distribution beam is fixed to the Bailey beam foundation, and the transverse distribution beams are arranged sequentially along the length of the Bailey beam foundation. The rail foundation is fixed at the center of the transverse distribution beam and is set along the length of the Bailey beam foundation. Two steel pipe pile foundations are provided, located on either side of the cross-river steel structure bridge construction. A gantry crane is installed on the rail foundation on both steel pipe pile foundations.

[0006] The beneficial effects of this utility model are as follows: Compared with the prior art, the track foundation device for the cross-river ultra-large gauge elevated gantry crane, constructed by the above-mentioned steel pipe pile foundation, Bailey beam foundation and rail foundation, enables the ground-based gantry crane to be set up in the air across the river. It has the advantages of simple and convenient construction, reusability, green environmental protection, enabling the gantry crane to move across the river, carrying out the installation and construction of cross-river steel structure bridges, reducing the construction period of cross-river steel structure bridges, saving construction costs, reducing the risk of high-altitude operations, and reducing water pollution.

[0007] Preferably, the steel pipe pile foundation includes steel pipes and scissor bracing, and the steel pipe pile foundation is formed by several groups of steel pipe piles arranged sequentially along the river crossing direction, with equal spacing between each group of steel pipe piles; each group of steel pipe piles consists of two symmetrically distributed steel pipes, and the scissor bracing is fixed between the two steel pipes; the steel pipe pile foundation arranged as described above is convenient for construction, and the equal spacing makes the stress more stable, resulting in better stability of the overall track foundation device during operation, and the scissor bracing further enhances the overall structural strength.

[0008] Preferably, the double-I-beam crossbeam is fixed across the center of two symmetrically distributed steel pipes, and the double-I-beam crossbeam is fixed on each group of steel pipe piles; the double-I-beam cross ...

[0009] Preferably, the Bailey bridge foundation is formed by sequentially splicing several sets of Bailey bridges along the river crossing direction. Each Bailey bridge includes Bailey bridge segments and connecting segments. Each set of Bailey bridges consists of six Bailey bridge segments and connecting segments. Two Bailey bridge segments are located on both sides of the Bailey bridge, and four Bailey bridge segments are closely attached to each other and located at the center of the Bailey bridge. Longitudinal limiting channel steel is fixed on both sides of the upper chord of the four Bailey bridge segments. The connecting segments are fixed between the Bailey bridge segments on both sides and the Bailey bridge segment at the center. By closely attaching the four Bailey bridge segments to each other and fixing longitudinal limiting channel steel on both sides, the entire Bailey bridge structure is made more stable. Furthermore, because the rail foundation is fixed at the center of the Bailey bridge foundation, the above-mentioned structural configuration results in better stress stability and improved safety performance during operation.

[0010] Preferably, the Bailey bridge foundation is provided with limiting components at both ends of its length direction. The limiting components include limiting blocks, which are fixed to the steel pipe pile foundations located at both ends of the river crossing direction. Because the contact area between the width direction of the Bailey bridge foundation and the double-I-beam crossbeam is large, it is not easy for displacement to occur. However, the length direction of the Bailey bridge foundation will be displaced due to the back-and-forth movement of the gantry crane. By setting the limiting blocks, the length direction of the Bailey bridge foundation is well limited and fixed.

[0011] Preferably, the transverse distribution beams are provided in a plurality of columns and arranged at equal intervals along the length of the Bailey beam foundation. The two ends of the transverse distribution beams are fixed to two Bailey beam pieces located on both sides of the Bailey beam by U-shaped clips. With the above structure, the transverse distribution beams and the Bailey beams are well fixed and evenly distributed, resulting in more uniform stress and better stability.

[0012] Preferably, the rail foundation includes several rails for installing the gantry crane, and the rails are arranged along the length of the Bailey beam foundation and spliced ​​together in sequence to form the rail foundation; this makes the splicing of the rails more convenient.
