Lifting and moving combined movable steel bridge

Abstract

The invention relates to a lifting and moving combined movable steel bridge. The bridge is mainly composed of a lifting bridge body, a moving bridge body, a hydraulic cylinder, a walking trolley, a counterweight body, an anchor device and a basic embedded part; a navigation hole is formed in one side of the moving bridge body, the lifting bridge body is arranged on the other side of the moving bridge body, the hydraulic cylinder is installed on the lower portion of the lifting bridge body, the moving bridge body is composed of an active bridge, a slave bridge and a connecting hinge pin, and the walking trolley, the anchor device and the counterweight body are arranged on the active bridge. In the drive-through state, the moving bridge body is erected above the navigation hole, the liftingbridge body falls down, and a flat pavement is formed; in the navigation state, the lifting bridge body is jacked, the moving bridge body retracts to the portion below the lifting bridge body, and navigation clearance is achieved. Accordingly, the bridge has the advantages of being good in trafficability, convenient to install and maintain, good in equipment protectiveness under high wind and thelike in technology, has the advantages of being small in occupied area, simple and attractive in building and the like in arrangement, and has the advantages of being capable of greatly reducing civilengineering capacity and effectively shortening the construction period in economic.

Description

technical field [0001] The invention relates to an opening bridge used in coastal water conservancy and navigation ship lock engineering, in particular to a lifting and moving combined movable steel bridge. Background technique [0002] At present, in water conservancy and shipping projects, the opening bridges used to connect the lock chamber roads on both sides of the navigation hole often adopt the following three methods: lifting type, rotating type, and mobile type. The lift-type open bridge is to lift the bridge body above the navigation clearance, so opening and closing buildings need to be installed on both sides of the navigation hole, resulting in a large amount of civil engineering and a long construction period; the rotary open bridge rotates the bridge body to leave space for navigation , but the bridge body is located above the water surface, which is inconvenient for installation and maintenance, and the structure needs to bear a large wind load; the mobile op...

Problems solved by technology

The lift-type open bridge is to lift the bridge body above the navigation clearance, so opening and closing buildings need to be installed on both sides of the navigation hole, resulting in a large amount of civil engineering and a long construction period; the rotary open bridge rotates the bridge body to leave space for navigation , but the bridge body is located above the water surface, which is inconvenient for installation and maintenance, and the structure needs to bear a large wind load; the mobile open bridge retracts the bridge body to the side of the navigation hole, but there is a height difference between the bridge body and the road on the connecting side, and it is necessary to Set up a section of approach bridge, resulting in a large area and affecting the trafficability of vehicles. It is difficult to apply in some occasions connecting high-grade roads
