Description

Technical Field

[0001] This utility model relates to the field of bridge reinforcement and renovation technology, specifically to a bridge bearing replacement device. Background Technology

[0002] Bridge bearings are crucial structural components connecting the superstructure and substructure of a bridge. Located between the bridge deck and the bearing pad, they reliably transfer the loads and deformations borne by the superstructure to the substructure, serving as a vital force transmission device. Bridge bearings are classified into two types: fixed bearings and movable bearings. Commonly used bearing types in bridge engineering include: asphalt or flat plate bearings, rubber plate bearings, spherical bearings, steel bearings, and special bearings.

[0003] Single-column piers are widely used in bridge structures due to their high utilization of substructure space, simple structure, and low cost. However, the supports and bearing pads at the top of single-column piers are often large, occupying a significant area on the pier top. This results in insufficient space for jacking equipment during later replacement work. Conventional temporary supports for jacking typically involve adding steel brackets or clamps to the top of the pier column. This method requires drilling holes in the pier sidewalls for reinforcement and necessitates custom-made steel components based on the pier dimensions. Consequently, jacking and replacing supports is inefficient and costly.

[0004] To address the aforementioned issues, Chinese Patent Application No. 202311543890.6 discloses a bridge bearing replacement device and method. The disclosed replacement device includes a clamp surrounding the bridge pier, a slide rail rotatably mounted on the clamp, a sliding seat slidably mounted on the slide rail, a drive rod hinged to the sliding seat, a mounting base mounted on the top surface of the bridge pier, and a first drive component for driving the sliding seat to slide. The slide rail is arranged parallel or perpendicular to the bridge's orientation and is fixedly mounted at the bottom of the bridge. The end of the drive rod away from the sliding seat is hinged to the mounting base, and the drive rod is inclined in the direction away from the pier. The sliding seat slides along the length of the slide rail. Chinese Patent Application No. 202110042938.X discloses a bridge bearing replacement auxiliary device and replacement method thereof. The disclosed device includes an upper auxiliary anchor plate, a lower auxiliary anchor plate, and two bridge bearings disposed between the upper and lower auxiliary anchor plates. The upper and lower auxiliary anchor plates are respectively provided with two mutually perpendicular guide grooves on opposite sides, and there is a solid section between the two guide grooves. The two bridge bearings are respectively installed in the two mutually perpendicular guide grooves.

[0005] While the aforementioned existing technology avoids drilling holes in the sidewalls of the pier for rebar installation, its structure is complex, including numerous components such as clamps, slide rails, sliding seats, drive rods, and multiple hydraulic cylinders. The installation process is cumbersome, requiring clamps to be installed on the pier body, slide rails to be fixed at the bottom of the beam, and adjustment of the installation rods. This results in low construction efficiency, poor device versatility, and the need to customize clamps and installation rods of different specifications for different pier diameters. The manufacturing cost is high, and it is difficult to reuse and utilize them efficiently. Utility Model Content

At the same time, the equipment can be transported to the next construction site for repeated use after disassembly, which significantly reduces the amortization cost of equipment for a single construction.
