Problems solved by technology

Since this type of opening bridge adopts the structure of a cantilever beam, the weight of the beam itself must be relatively large, and the weight of the supporting balance weight block is even greater, so the weight of this type of opening bridge is generally very large, and the opening part The weight has a decisive influence on the overall cost of the project, so this type of open bridge has not been promoted in engineering practice

Abstract

The present invention relates to a light-type vertically-turning opening bridge. It includes a main frame, said main frame is composed of oblique tower and bridge floor, said oblique tower is connected with one end of said bridge floor, and said one end where the oblique tower and bridge floor are mutually connected is set on the base seat and is turnably connected with said base seat, between said oblique tower and bridge floor an oblique guy rope is set and two ends of said oblique guy rope are respectively connected with said oblique tower and bridge floor, on the main frame a balance weight block is set, and said balance weight block can be slidden on said main frame.

Description

technical field [0001] The invention relates to a bridge, in particular to a light-duty vertically rotating open bridge that can be opened and closed. Background technique [0002] In the current prior art, the opening bridge is mostly composed of a cantilever beam configuration and a balance weight block opposite to the direction of the cantilever. Since this type of opening bridge adopts the structure of a cantilever beam, the weight of the beam itself must be relatively large, and the weight of the supporting balance weight block is even greater, so the weight of this type of opening bridge is generally very large, and the opening part Weight has a decisive influence on the overall construction cost of the project, so this type of open bridge has not been promoted in engineering practice. Contents of the invention [0003] The invention provides a light-duty vertical rotation opening bridge capable of reducing the weight of the opening structure. [0004] The present ...
