Abstract

The invention, which belongs to the technical field of bridge construction machinery and methods, is named as a low-level girder transporting vehicle and a bridge erection and installation method. Theinvention mainly provides a low-level transporting girder vehicle comprising a vehicle body, telescopic support legs, a box beam jacking cylinder, a suspension running assembly, a truss mechanism, atruss mechanism traction system, a steering cylinder and driver cabs. The telescopic support legs and the box beam jacking cylinder are arranged at the vehicle body respectively; the driver cabs are arranged at the front end and the rear end of the vehicle body; and a rotating mechanism is arranged between the driver cabs and the vehicle body. The vehicle body has a U-shaped structure and is provided with a track. The truss mechanism is arranged on the track and is connected with the truss mechanism traction system. The suspension running assembly and the steering cylinder are arranged below the vehicle body; and the steering cylinder is connected to the vehicle body and the suspension running assembly. The low-level transporting girder vehicle can be applied to transportation of different-span box beams for tunneling and bridge erection construction.

Description

technical field [0001] The invention belongs to the technical field of bridge construction machinery and methods, and in particular relates to a low-level beam transport vehicle suitable for transporting different box girders and a bridge erection construction method. Background technique [0002] There are two main types of beam transport vehicles currently in use: tunnel beam transport vehicles and tunnel beam transport vehicles, also known as high beam transport vehicles and low beam transport vehicles. The structures of the two types of beam transport vehicles are basically the same: they both use a frame with the main girder placed in the middle, tire groups are distributed longitudinally and evenly on both sides of the main girder, and are fully hydraulically driven. The difference is that high-position beam transport vehicles usually use large-size tires to reduce the number of bearing axles while meeting the beam transport conditions, but the height of the beam trans...
