Abstract

The invention relates to a rotation movable bridge based on a lifting tower rack. The movable bridge comprises a base, a fixed bridge body is connected with the base through support pillars, a movable bridge body is arranged on one end of the fixed bridge body; the bottom surface of the movable bridge is connected with a hinge seat and a movable bridge lifter, the flexible end of the movable bridge lifter is connected with the bottom surface of the movable bridge body; the other end of the fixed bridge body is provided with a movable tower rack, the top of the movable tower rack is provided with tower rack pulleys, a motor is further arranged on the end of the movable tower rack farther from the movable bridge body; the movable tower rack can make rotations around a pivot of the rack bottom; the movable bridge body is connected with several traction steel cables, the other ends of the steel cables are connected with the motor, and the steel cables are in slide fit with the tower rack pulleys. The rotation movable bridge based on the lifting tower rack is clear in force structure and beautiful in structure, when the movable bridge is lifted by the movable bridge lifter, the concrete base is under compression, and the compression resistance of the concrete is well utilized. Hydraulic hoist is adopted by the movable bridge for control, the operation is reliable. And the speed of opening and closing is high, the rhythm is smooth, the smoothness of airway traffic is guaranteed.

Description

technical field [0001] The invention relates to road and bridge facilities, in particular to a rotating movable bridge based on a lifting tower. Background technique [0002] At present, the common rotary movable bridge adopts a tower at one end of the movable bridge, and uses steel wire and cable traction to make the movable bridge rotate around the fixed hinge support in the facade. When the ship is about to pass, the bridge span is raised to temporarily interrupt the traffic on the bridge. After the ship passes, it is lowered back to its original position to resume land traffic. This type of movable bridge generally requires a higher tower, which affects the overall landscape effect of the structure. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a rotating movable bridge based on a lifting tower that does not require a permanent tower structure. [0004] The technical scheme that the present invention solv...
