Abstract

The invention discloses a bridge erecting machine for a cable-stayed bridge and a suspension bridge. A bridge 1 comprises a beam 2, a rod 3 and a joint 4 at the top of the rod 3. The bridge 1 comprises two structures including the cable-stayed bridge 1-1 and the suspension bridge 1-2. A beam erecting machine 5 comprises a rack 5-1 and a crane 6, and the front end of the rack 5-1 is located on theouter side of the X direction of the installed beam 2. The rack comprises two side rack bodies 5-1-1, a top rack body 5-1-2, a front end bottom rack body 5-1-3, a tail fixing device 7 and a rail 8 forthe crane 6 to run. The tops of the two side rack bodies 5-1-1 are connected with the top rack body 5-1-2, the bottoms of the front ends of the two side rack bodies 5-1-1 are connected with the frontend bottom rack body 5-1-3, the front end bottom rack body 5-1-3 does not influence transportation and hoisting of the beam 2, the rail 8 is fixed to the upper portion of the top rack body 5-1-2, thecrane 6 runs on the rail 8, and the space between the lower portion of the crane 6 and the two side rack bodies 5-1-1 serves as a conveying channel 5-2 of the beam 2. The bridge erecting machine hasthe advantages that the bridge erecting machine uses the erected beam and a hoisting rod of the suspension bridge or the cable-stayed bridge to complete erection of the whole beam, construction is easy, and the construction period is short.

Description

technical field [0001] The invention relates to a bridge erecting machine for cable-stayed bridges and suspension bridges, and belongs to the technical field of bridge erection engineering for cable-stayed bridges and suspension bridges. Background technique [0002] The existing suspension bridges mostly use steel truss stiffening beams, which are constructed by the cantilever assembly method of walking deck cranes. [0003] The track is laid on the steel truss stiffening beam that has been erected, and then the walking deck crane moves forward to erect the next section. The on-site assembly workload is heavy and the hoisting and lifting tools are complicated. Contents of the invention [0004] What the present invention proposes is a kind of bridge erecting machine that is used for cable-stayed bridge and suspension bridge, and its purpose aims at overcoming the defective that prior art exists, and its main advantage: bridge erecting machine utilizes the girder that has ...
