Pivoted bridge pivot body device

Abstract

Provided is a pivoted bridge swivel body device. The device comprises a pivot body support base, an annular slide track, multiple support feet, a first traction unit and a second traction unit; the pivot body support base comprises a lower spherical pendulum and an upper spherical pendulum which are fixed to a fixed part of a pivot body bridge and a rotary part of the pivot body bridge respectively; the annular slide track is fixed to the upper surface of the fixed part; the support feet are fixed to the lower portions of the rotary part and can slide on the annular slide track; the first traction unit drives the rotary part to rotate clockwise by exerting action force which can make the rotary part capable of sliding on the annular slide track clockwise on the rotary part through a traction cable; the second traction unit drives the rotary part to rotate anticlockwise by exerting action force which can make the rotary part capable of sliding on the annular slide track anticlockwise onthe rotary part through a traction cable. The pivoted bridge swivel body device can make the pivot body bridge capable of not only pivoting from a construction site to a work site but also pivoting back to the construction site from the work site, and thus the maintenance of the pivot body bridge is facilitated.

Description

technical field [0001] The present invention generally relates to the field of swivel bridges, and in particular to a swivel device of a swivel bridge, specifically a swivel bridge swivel device. Background technique [0002] The swivel bridge is a bridge constructed by the swivel method. Specifically, it refers to the construction of bridge parts that cross rivers, roads, and railways on both banks or both sides of the road. The rotation of the beam body on both sides reaches the working position of the bridge, and at the working position, the two parts are closed to form a whole bridge. The bridge swivel technology can convert the operation above the obstacle into the operation on the shore or near the ground, which can not only ensure the safety of the project construction, but also reduce the impact on traffic, shorten the closure time, and reduce the construction cost. [0003] The swivel bridge is driven by the rotation of the swivel support from the construction site...

Problems solved by technology

However, in the prior art, the swivel support can only rotate the bridge from the construction site to the working site. When the bridge needs to be repaired or removed after a period of use, the bridge cann
