Abstract

The invention relates to the technical field of bridge reinforcement, and concretely relates to a bridge lifting device, a bridge transformation system and a bridge transformation construction method.The method comprises the following steps that S1, a to-be-lifted bridge section is lifted through a lifting unit arranged at the lifting ends of two bridge lifting mechanisms and temporarily supported; S2, the two bridge lifting mechanisms are moved to the two sides of the next to-be-lifted bridge section till lifting and temporary supporting of all the bridge sections are completed; S3, two setsof semi-frame bodies are placed on the ground on the two sides of the lifted bridge section, and the lifting device is arranged above the two sets of semi-frame bodies; S4, the lifting device lifts the two sets of semi-frame bodies to the preset height and then moves to the installation position of a construction hanging bracket, and the two sets of semi-frame bodies are arranged on a pier in a sleeving mode after being spliced; and S5, connection between the lifting device and the semi-frame bodies is removed, and step S3 and step S4 are repeated to install the next construction hanging bracket. The problems that in the prior art, a hydraulic jack is adopted for pier heightening, the jacking stroke is limited, a specially-designed steel cushion block needs to be adopted, and the construction efficiency is low can be solved.

Description

technical field [0001] The invention relates to the technical field of bridge reinforcement, in particular to a bridge hoisting device, a reconstruction system and a reconstruction construction method. Background technique [0002] Bridge pier connection construction is a more efficient and economical construction method in bridge reconstruction construction. It is commonly used in urban overpass reconstruction, and its main purpose is to adjust the elevation of existing bridges. [0003] In the existing construction method, before construction, it is necessary to set up a chassis structure system on the existing bridge piers, which is mainly used to bear the jacking load and transfer the load to the lower bridge piers or the foundation structure; set up a pallet structure system, which is mainly used for supporting The upper part is jacked up from the structure. A hydraulic jack is placed between the chassis structure and the pallet structure. After the existing pier is cu...
