Problems solved by technology

[0003] The first is the traditional road bridge that is only pulled by steel wires. During use, due to the friction generated by the steel wires during use, the steel wires need to be replaced regularly, which increases maintenance costs and poses safety hazards.
[0004] The second is the road bridge that only uses oil cylinders as...

Abstract

The invention relates to the technical field of highway bridges, in particular to a vertical jacking movable highway bridge. The vertical jacking movable highway bridge comprises an oil cylinder supporting assembly, a steel rope traction assembly and a highway bridge body; the oil cylinder supporting assembly comprises a first supporting oil cylinder and a second supporting oil cylinder, and the first supporting oil cylinder and the second supporting oil cylinder are installed in a left groove and a right groove below the ground at the two ends of the highway bridge body; guide rails are correspondingly arranged at the two sides of the inner walls of each of the left groove and the right groove; guide wheels are correspondingly arranged at the two sides of the tops of cylinder shafts of each of the first supporting oil cylinder and the second supporting oil cylinder; the tops of the cylinder shafts of the first supporting oil cylinder and the second supporting oil cylinder are connected with the two sides of the bottom face of the highway bridge body respectively. According to the vertical jacking movable highway bridge, through the cooperation of rope pulling traction of steel ropes and jacking of the supporting oil cylinders, dual purposes of pull-up or descending are achieved, and thus jacking and descending of the bridge body are guaranteed; the vertical jacking movable highway bridge is convenient to operate, dual jacking protection is achieved, hidden safety hazards are avoided, normal use of the highway bridge body is guaranteed, and the maintenance cost is also reduced.

Description

technical field [0001] The invention relates to the technical field of road bridges, in particular to a vertical jacking movable road bridge. Background technique [0002] With the continuous rapid development of social roads, road bridges are widely used as a kind of construction facilities. As a kind of bridge that can be opened, the movable road bridge is often used to meet the needs of shipping and facilitate the passage of ships. After the passage is completed, the bridge is closed so that the bridge and the road are on the same plane, which is convenient for pedestrians and vehicles. One thing is multi-purpose. Due to the weight of the bridge, the traditional movable road bridge usually uses a motor or a hydraulic system to drive the winch, and uses a wire rope to make the road bridge rise or fall. And the patent of patent No. 201621153976.3 adopts jacking oil cylinder to carry out for highway bridge. There are following problems in above-mentioned highway bridge whe...
