Mobile platform carrying and erecting integrated machine and bridge erecting method

Abstract

The invention discloses a mobile platform carrying and erecting integrated machine, bridge erecting equipment and a bridge erecting method. The invention aims to provide a mobile platform carrying and erecting integrated machine with good stability and convenience in use. The mobile platform carrying and erecting integrated machine disclosed by the invention comprises a carrying and erecting beammachine and a mobile platform guide beam machine, wherein the carrying and erecting beam machine comprises a main beam, a front walking wheel group, a rear walking wheel group and a hoisting mechanism; the mobile platform guide beam machine comprises a guide beam, a folding support leg, a front roller support leg, a middle roller support leg, a rear roller support leg and a mobile platform erecting beam trolley; the mobile platform erecting beam trolley on the guide beam is provided with an engine and a pump station; mobile platforms are mounted on the two sides; and the height of each mobileplatform can be adjusted by controlling a lifting oil cylinder. When a bridge is erected, the front walking wheel group of the carrying and erecting beam machine can walk onto each mobile platform, and the mobile platform erecting beam trolley can perform longitudinal translation through the guide beam so as to realize more bridge erecting functions; and the mobile platforms can be folded so as to conveniently carry the equipment to another construction site, and each mobile platform is provided with wheels and connected with the erecting beam trolley.

Description

Technical field [0001] The invention relates to a bridge erection equipment, in particular to an integrated bridge erecting machine for transporting and erecting beams. Background technique [0002] At present, the existing integrated bridge erecting machine for transporting and erecting beams, such as the one disclosed in the Chinese utility model patent ZL200420115944.4, requires the guide beams to be retracted many times to make the front of the beam erecting machine. The walking wheels can fall on the bridge deck, resulting in many procedures in the erection process, time-consuming and labor-intensive, and low efficiency. And when erecting at the entrance and exit of the tunnel, due to the difference in the height of the guide beam and the bridge abutment when the beam transport machine and the guide beam frame beam are used, the stability of the equipment and the smooth transition of the equipment load and construction safety are greatly affected. In view of the above-menti...
