Equipment and construction method for bridge replacement

Abstract

The invention particularly relates to equipment for bridge replacement and a construction method. The equipment for bridge replacement at least comprises a bottom plate, a lifting mechanism arranged on the bottom plate, a slide bar assembly, a telescopic assembly and a clamping assembly; the slide bar assembly comprises a strip-shaped track groove connected to one side of the bottom plate in a parallel mode and a lead screw mechanism, wherein the two ends of the lead screw mechanism are erected at the two ends of the strip-shaped track groove; the telescopic assembly comprises a longitudinal telescopic mechanism and a transverse telescopic mechanism, wherein a slide block is connected to the bottom of the longitudinal telescopic mechanism through a connecting rod, the slide block is arranged in the strip-shaped track groove, and a nut matched with the lead screw mechanism is connected to one side of the connecting rod; the transverse telescopic mechanism is connected to the side end ofthe top of the longitudinal telescopic mechanism with through a connecting plate; and the clamping assembly comprises a clamping bottom plate arranged at one side of the transverse telescopic mechanism and a clamping mechanism arranged at the other side of the clamping bottom plate, wherein the clamping mechanism is a pair of clamping rods capable of clamping a rubber supporting seat of a bridge.The equipment and the construction method can self-position and automatically grab the bridge supporting seat to realize replacement of the old and new bridge supporting seats.

Description

technical field [0001] The invention belongs to the technical field of road and bridge construction, and in particular relates to equipment and a construction method for bridge replacement. Background technique [0002] The bridge support is erected on the abutment, and its top surface supports the upper structure of the bridge. The bridge support mainly includes two functions: to bear various loads acting on the superstructure and transmit it reliably to the piers; to make the rotation angle and displacement of the superstructure conform to the design diagram without generating additional additional internal forces; However, due to the aging of components, earthquakes, vehicles and ships hitting bridge piers and other reasons, the bridge bearings are damaged and damaged to varying degrees, which affects the quality of the bridge and the safety of traffic; at the same time, with the development of the transportation industry, the traffic flow and vehicle load on the bridge ...

AI Technical Summary

Problems solved by technology

However, this structure does not realize the automatic entry of the bridge support into the transmission device, and still requires workers to pick and place the old and new bridges, and the support assembly integrates fixation, telescopic transmission and jack equipment through the support plate, resulting in its heavy weight and bulky characteristics. Not conducive to hanging transportation and installation
