[0002] With the rapid development of global infrastructure construction, the span and structural complexity of bridge projects are increasing. Traditional bridge construction methods are difficult and inefficient when faced with bridges with large spans and complex structures. They pose many safety risks and have a significant impact on the environment. Therefore, there is an urgent need for intelligent and automated bridge construction equipment to improve construction efficiency, ensure construction safety, and reduce environmental impact.

[0003] The Chinese invention patent with publication number CN115341486A disclosed on November 15, 2022, a bridge-building machine for cantilever casting construction, comprising a main truss and an inner mold. The inner mold comprises an inner mold body, an inner mold hanging beam, and an inner mold guide beam. The front end of the main truss is provided with a crossbeam that can provide support for the inner mold guide beam. The inner mold body is provided on the inner mold hanging beam, and the inner mold hanging beam is provided with an inner mold hanging rod. The inner mold guide beam and the inner mold body can slide relative to each other. In the present invention, before the steel cage is hoisted as a whole, the inner mold body is anchored to the cast continuous beam segment by the inner mold hanging rod, the inner mold guide beam slides into the cast continuous beam segment, and then the hanger hoists the steel cage to the installation position. The inner mold will not affect the overall hoisting of the steel cage. After the steel cage is in place, the front end of the inner mold guide beam slides onto the cross beam and is supported by the cross beam. Then the inner mold hanger is loosened, and the inner mold body slides forward along the inner mold guide beam to the section to be cast. There is no need to assemble the inner mold on site, which is conducive to further shortening the construction period. The overall structure is simple, effective and easy to operate.

[0004] However, the above-mentioned disclosed solutions have the following shortcomings: the bridge-building machine in the prior art cannot be deformed and adapted according to the shapes of bridge structures of different shapes, so it plays a limited role in the construction process of the bridge, and therefore cannot effectively improve the efficiency of bridge construction. Utility Model Content

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] Furthermore, two ends of the third movable frame are respectively connected to the first artificial platform and the second artificial platform.

[0009] Furthermore, a third artificial platform is connected to the main structure corresponding to the shoulder beam.

[0010] Furthermore, the first movable frame and the second movable frame are detachably fixed to the main structure.

[0011] Furthermore, the main structure is detachably connected to the lower end of the suspension unit.

[0012] Furthermore, the horizontal track can be detachably fixed to the upper crossbeam structure of the bridge.

[0013] The super-large cantilever bridge intelligent bridge-building machine provided by the utility model has the following beneficial effects:

[0014] 1. The utility model fixes the horizontal track on the upper beam of the built bridge, then adjusts the position of the positioning fixing seat on the horizontal track to determine the initial position of the moving range, and then connects the reciprocating cylinder and the hanging seat unit, and connects the main frame, the shoulder beam, the first movable frame, the second movable frame, the climbing ladder and the third movable frame under the hanging seat unit, so that a large number of workers can stand on the bridge-building machine to work. After pouring a part, the reciprocating cylinder pushes the hanging seat unit and the main frame to move, so that the bridge-building work can continue. Through mechanical displacement, the displacement efficiency is high and the precision is high, which can effectively improve the bridge-building efficiency and solve the problem of low efficiency of existing bridge-building machines.

[0015] 2. The utility model is fixed on the upper crossbeam structure that is initially cast as a reference. The bridge-building machine is usually designed with the load-bearing structure located below, that is, the working platform and the formwork system are suspended below, and the supporting structure is fixed on the already constructed bridge section. This design enables the bridge-building machine to move along the lower edge of the bridge to provide support for the newly cast bridge section. It can be gradually moved forward as the construction progresses. After each section of the bridge is cast, the bridge-building machine moves forward to the next construction position through its traveling system, thereby realizing the cantilever construction of the bridge section by section and achieving highly efficient bridge construction, solving the problem of low efficiency of existing bridge-building machines.
