Description

Technical Field

[0001] The utility model relates to the technical field of steel box girder jacking systems, in particular to a deviation-correcting bracket device of a steel box girder jacking system. Background Art

[0002] Steel box girders are increasingly being used in the construction of long-span bridges and other large structures, and the installation and jacking construction of steel box girders is a very complex process that requires high precision. During the jacking construction process, the precise positioning and deviation correction of the steel box girders are key to ensuring the quality of the project. Due to the complexity of the construction site and the weight and inertia of the steel box girders themselves, the steel box girders are prone to lateral or longitudinal deviation during the jacking process, and this deviation may affect the overall mechanical properties and structural stability of the bridge. Currently, the deviation correction equipment on the market mostly relies on simple mechanical push-pull, lacking precise control of the deviation correction angle. At the same time, the fixation and repositioning during the deviation correction process also have certain limitations, and cannot effectively prevent the deviation from occurring again after the deviation correction is completed. Therefore, there is an urgent need for a device that can accurately adjust the deviation correction angle and ensure a stable and effective deviation correction process to improve the accuracy and efficiency of the jacking construction of steel box girders.

[0014] 3. Positioning stability after correction: After the correction is completed, the telescopic component pushes the movable block against the inner wall of the rotating seat to ensure that the movable seat and the bracket will not undergo secondary displacement after the correction, effectively avoiding the offset problem caused by the inertia of the steel box girder or external force after the correction is completed, and ensuring the long-term stability and accuracy of the correction operation.

[0015] 4. Easy installation and flexible operation: The device adopts a modular design. The connection between movable seat 1, movable seat 2 and the bracket is simple and reliable.

According to the angle of correction required, the position of the movable seat 10 on the circumference of the base 1 is adjusted by turning, and the angle scale line 4 is used to judge whether the adjusted angle of the movable seat 10 meets the correction requirements. When the position adjustment of the movable seat 10 is completed, the movable seat 10 is tightened and positioned by bolts, and the movable seat 2 11 is pushed horizontally in the rotating seat 5 by the hydraulic cylinder 9, thereby pushing the bracket 8 and the steel box beam to move to achieve correction. After the correction is completed, the telescopic component 14 pushes the movable block 15 to move until the side of the movable block 15 is against the inner wall of the rotating seat 5, thereby achieving the positioning of the movable seat 2 11 and the bracket 8, avoiding the situation where the bracket 8, movable seat 2 11 and the steel box beam are offset again after the correction is completed, thereby ensuring the effectiveness of the correction.
