Pitching rotating steel bridge for ship lock

Abstract

The invention discloses a pitching rotating steel bridge for a ship lock, which comprises a bridge pier, a bridge deck, a main girder and a driving assembly. A base is prefabricated inside the top of the bridge pier, and the upper end of the base is connected with a support seat above the bridge pier through bolts. , the main girder is connected to the upper end of the support seat through a rotating shaft, and the inner side of the main girder is connected with a crossbeam by bolts. The present invention adds a steel bridge infrastructure composed of piers, bridge decks, main girders and drive components. The drive components are used for Drive the main girder to rotate and lift along the rotation axis of the support base, change the connection state of the bridge deck components, facilitate the passage of ships below, add material box components at the bottom of the pier, when the propulsion mechanism pushes the material box full of materials through the push plate When pushing out, the end of the material box will be pre-inserted into the through groove of the side wall of the cover plate and docked with the box cover, so that the material box is inserted into the inner side of the box cover, and the material box and the box cover are combined together to facilitate the closure of the material box and avoid material leakage. Debris scattered inside the box.

Description

technical field [0001] The invention relates to the technical field of steel bridges, in particular to a pitch-type rotating steel bridge for a ship lock. Background technique [0002] Steel bridges are bridges that use steel as the main construction material. It has the characteristics of high strength and high rigidity. Compared with concrete bridges, the beam height and self-weight can be reduced. Due to the isotropy of steel, the uniform texture and the large elastic modulus, the working conditions of the bridge are more consistent with the assumptions in the calculation diagrams. Steel bridges are generally prefabricated in factories and spliced ​​on site. The construction period is short, the processing is convenient and not affected by the season, the steel has high strength, superior performance, and the ratio of apparent density to allowable stress is small. Component manufacturing is most suitable for industrialization, transportation and installation are more con...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a pitching rotary steel bridge for ship locks. By increasing the propulsion mechanism to cooperate with the push plate assembly, the material box is driven to cooperate with the box cover, so as to facilitate the collection of debris scattered on the bridge deck, which solves the problem of existing bridge deck problems. When lifting, it will fall with the bridge deck and be scattered near the bridge piers, which will easily cause environmental pollution, affect the environment, and be inconvenient to recycle.
