[0002] A bridge generally refers to a structure built across rivers, lakes, and seas to enable vehicles and pedestrians to pass smoothly. The longitudinal beam of a bridge, also known as the main beam of a bridge, is the beam that bears the main longitudinal load in the bridge structure. Among the various components of a bridge, the longitudinal beam plays a vital role. It directly bears the load from the bridge deck (such as vehicles, pedestrians, etc.) and transfers it to the supporting structure of the bridge, such as piers and bridge towers.

Traditional installation methods usually rely on large lifting equipment, such as cranes, to lift the longitudinal beams to the predetermined location. However, in some cases, such as areas with complex terrain, limited space, or high environmental protection requirements, traditional lifting equipment may not be able to reach the installation site, which makes the installation of bridge longitudinal beams complicated and difficult. Therefore, we propose an auxiliary support mechanism for bridge longitudinal beams to solve the above problems. Summary of the invention
