[0002] The development of domestic bridge technology is moving towards large span, lightweight and low cost, especially in the field of railway bridges. With the development of railway bridges, there are more and more large-span railway bridges that use hybrid bridges of concrete and steel structures.

[0003] Traditional all-concrete bridges are generally constructed with a full hanging basket; all-steel bridges are generally constructed with a bridge crane. There are also a variety of construction methods for mixed concrete and steel bridges, the main methods include: 1. The overall vertical lifting method of the steel beam segment, that is, the large-tonnage steel beam is transported as a whole to the bottom of the waiting position by ship, and the hoisting machine, hoisting machine and other mechanisms are used to lift the whole vertically into place; 2. The segmented vertical lifting method of the steel beam: the steel beam is divided into small sections, and transported to the bottom of the waiting position by ship or car for vertical lifting. In addition to solving the lifting and hoisting of the steel beam, this type of bridge has the difficulty of not being able to pass The bridge deck is used to transport and hoist steel beam segments; the above methods all require that the steel beams be transported to the position directly below the bridge deck, and after the steel beams are lifted into place, brackets are set at the joints for support, and then a formwork is set to pour concrete in the joint section. The relevant equipment and methods require that the steel beam segments must be transported directly below the bridge deck, which limits the application scenarios of this type of bridge, especially for bridges across highways. The steel beams cannot be transported to the position to be lifted and lifted vertically, and brackets cannot be set to construct the joint section, which in turn limits the application scenarios of this type of steel-concrete combined bridge.

Then, this mechanism achieves the advantage of hoisting the steel beam while the concrete structure is being poured and constructed, and solves the problem that the steel beam cannot be lifted vertically under specific restrictive conditions in the prior art, and the concrete segment and the concrete at the joint of the steel beam cannot be poured synchronously.
