Bridge swivel device capable of rotating stably and construction method thereof

Abstract

The invention belongs to the technical field of bridge rotation, and relates to a bridge rotation device capable of stably rotating and a construction method thereof. A supporting column is fixedly mounted at the top of a bottom plate, and a hydraulic push rod output shaft fixedly mounted at the top end of the supporting column is fixedly connected with the inner wall of the top of a lifting coverslidably connected to the supporting column; a supporting plate is rotationally connected to the top of a supporting disc fixed to the top of the lifting cover, two mounting columns rotationally connected with a containing plate are symmetrically and fixedly mounted at the top of the supporting plate, a mounting pipe is slidably connected to sliding covers symmetrically and fixedly mounted at thetop of the supporting plate, and the tops of two movable covers in threaded connection with the inner wall of the mounting pipe are in transmission connection with the bottom of the containing plate.A supporting shaft is fixedly installed at the bottom of the supporting plate, the bottom end of the supporting shaft is rotationally connected with the top of a supporting disc, and the problems that an existing bridge rotating body device only adjusts plane rotation of a bridge plate and is not provided with a related longitudinal adjusting device, so that the bridge rotating body adjusting range is narrow, and the application range is affected are solved.

Description

technical field [0001] The invention belongs to the technical field of bridge swivels, and relates to a smoothly rotating bridge swivel device and a construction method thereof. Background technique [0002] With the rapid development of the national economy, the transportation industry has been vigorously developed. Due to the influence of some terrain or existing traffic facilities, the bridge swivel construction method is more and more widely used in bridge construction. Compared with the traditional construction technology, the swivel construction technology has the characteristics of not interfering with traffic, uninterrupted navigation, crossing deep ditches, rivers, and roads with frequent traffic, and the construction is fast and cost-effective. [0003] The currently widely used bridge swivel construction is to prefabricate the bridge body first with a simple bracket, and then use the bridge swivel device to rotate the bridge body at a preset angle, and combine th...

Problems solved by technology

[0005] In view of this, in order to solve the problem that the existing bridge swivel device only adjusts for the planar rotation of the bridge deck, there is no related longitudinal adjustment device, resulting in a narrow adjustment range of the bridge swivel, which affects its application range, and provides a stable rotation The bridge swivel device and its construction method
