Vertical lifting mobile highway bridge

Abstract

A vertical lifting mobile highway bridge comprises a bridge body structure, wherein hydraulic lifting mechanisms are arranged on the left side and the right side of the lower part of the bridge body structure; and horizontal locking mechanisms are arranged on bent frame columns on the left side and the right side of the bridge body structure. The hydraulic lifting mechanisms comprise lifting cylinders and fixed supports, wherein piston rods of the lifting cylinders are connected with the bridge body structure through supports. The horizontal locking mechanisms comprise horizontal cylinders and locking beams, wherein piston rods of the horizontal cylinders are connected with the locking beams through supports. Through adoption of the vertical lifting mobile highway bridge provided by the invention, a problem that the cylinders of the the traditional ship-passing structure folding mobile highway bridge are easy to be interfered with navigation ships during extending out when the traditional ship-passing structure folding mobile highway bridge is unfolded is solved, and navigation efficiencies of water conservancy navigation structures such as ship lifts, ship locks and so on are increased.

Description

technical field [0001] The invention relates to a movable bridge, in particular to a vertical jacking movable highway bridge used in the navigation field. Background technique [0002] The movable road bridge is a bridge that can be opened. In order to meet the needs of shipping, it can be opened when it is above a certain navigable water level, so that ships passing the ship lift (or ship lock) can pass smoothly. After the navigation is completed, or when it is below a certain navigable water level, the bridge is not opened and the bridge is closed. The elevation of the bridge deck is flush with the concrete roads on both sides, and vehicles and pedestrians can pass through. [0003] The active road bridge in the prior art usually uses a motor or a hydraulic system to drive the hoist, pulls the wire rope through the hoist, and relies on the wire rope and the wire rope drum to transmit power to make the active road bridge rise or fall. This type of active road bridge is ofte...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a vertical lifting movable road bridge, which solves the problem that when the existing ship-passing building is opened, the oil cylinder easily interferes with the navigable ship when the open-type movable road bridge is opened, and improves the lifting capacity of the ship.
