An erection vehicle and bridge erection method for a prefabricated highway steel bridge

Abstract

The invention discloses an erection working vehicle for a prefabricated highway steel bridge, and belongs to the technical field of bridge erection. The erection working vehicle comprises a chassis cab, a crane, a box-type freight container, an erection platform and a hydraulic system, wherein the crane is fixed on a chassis frame of the chassis cab; the box-type freight container is fixed on thechassis frame and behind the crane; the erection platform is mounted in the box-type freight container; hydraulic lifting support legs are mounted at the bottom of a machine frame of the erection platform; an erection roller group is mounted on the upper surface of the machine frame; a bridge-pulling winch is fixed to the side surface of the machine frame; a steel wire rope is wound around the bridge-pulling winch; a hydraulic pipe is mounted on the machine frame; one end of the hydraulic pipe is detachably connected to the hydraulic system and the other end of the hydraulic pipe separately communicates with the hydraulic lifting support legs and the bridge-pulling winch; and the hydraulic system is mounted on the chassis cab and used for providing a driving force for the hydraulic liftingsupport legs and the bridge-pulling winch. The working vehicle and a bridge erection method can solve the problem of difficulty in manually erecting the prefabricated highway steel bridge.

Description

technical field [0001] The invention belongs to the technical field of bridge erection, and in particular relates to an erection operation vehicle and a bridge erection method of an assembled highway steel bridge. Background technique [0002] Prefabricated highway steel bridge is an important bridge equipment for traffic readiness in my country, which mainly relies on manual erection.
