Abstract

The invention discloses a lift bridge and belongs to the technical field of bridges. The lift bridge comprises a horizontal bridge body arranged above a river channel. The two sides of the river channel are each provided with two supporting towers, the four corners of the bridge body are each provided with a lift arm, and the upper side of each lift arm is provided with a movable pulley block. The upper portions of the supporting towers are provided with fixed pulley blocks. A crossbeam is fixed between the supporting towers on the same side of a river bank, each crossbeam is provided with a drive device which comprises a rotary rope tube, and a lift wire rope is wound around the fixed pulley blocks and the movable pulley blocks to be wound around the rope tube. Each lift arm is further provided with an anchoring piece which is connected with one end of a balance wire rope, the upper portion of each supporting tower is further provided with a reversing guide wheel, the balancing wire ropes are wound around the reversing guide wheels, and balance weights are connected to the other ends of the balance wire ropes. In work, the balance weights can balance most gravity of the bridge body, the drive mechanism can ascend and descend the bridge body just with low power, and the lift bridge is simple in structure and low in operation energy consumption, and can be applied to the river channels which need to be open to navigation frequently.

Description

Technical field [0001] The invention relates to a bridge device, in particular to a bridge device that can be raised and lowered. Background technique [0002] In the Chinese patent database, there is a balanced motorized lift bridge, its application number: 90110096.X, application date: 1990-12-21, publication number: CN1052643; publication date: 1991-07-03, the two ends of the bridge body of the device The bridge boxes are set symmetrically, one or two at each end. The bridge is composed of bridge boxes, operating platforms, steel wire ropes, hoistway columns, bridge bodies, beams, beam slabs, steel wire rope wheels, main beams and auxiliary power devices. The bridge body and main beams Supported by hoistway columns or bridge piers, one or two bridge boxes are set at each end of the bridge body, and the operating platform is installed in the bridge boxes. The bridge boxes are connected by steel wire ropes, and they are suspended from the steel wire ropes installed on the beams ...
