Problems solved by technology

For example: for a typical type of bridge erecting machine, as the length of the concrete box girder increases, the length of the main girder also increases, which will increase the length and weight of the bridge erecting machine. The rigidity of the main girder, carrying the girder through the tunnel, and the construction load and operability of the erected girder are all unfavorable

Abstract

The invention provides a transporting and erecting integrated bridge girder erection machine of rear cart three rows of tires. The transporting and erecting integrated bridge girder erection machine comprises a main beam, a front vehicle, a rear vehicle, a main support, a subsidiary support and a hanging beam crown block; the rear cart comprises a rear cart cross beam connected to the bottom of the main beam, rear cart longitudinal beams are arranged at the bottoms of the two sides of the rear cart cross beam, the bottoms of the middles of the rear cart longitudinal beams are connected to rearcart middle-row wheels through rear cart middle-row wheel set hanging hydraulic cylinders, the bottoms of the rear cart longitudinal beams are connected to rear cart two-side wheels through rear carttwo-side wheel set hanging hydraulic cylinders respectively, the rear cart middle-row wheel set hanging hydraulic cylinders and the rear cart two-side wheel set hanging hydraulic cylinders are connected to the output ends of hydraulic pumps through hydraulic pipes respectively, the input ends of the hydraulic pumps are connected to an engine through a reduction box, and the hydraulic pipes are provided with pressure regulating valves respectively. Through the transporting and erecting integrated bridge girder erection machine of the rear cart three rows of tires, the problems are solved thatas the lengths of concrete box girders increase, existing bridge girder erection machines are disadvantageous to main beam rigidity, construction load of a subsidiary beam passing a tunnel and an erected bridge and operability.

Description

technical field [0001] The invention relates to a bridge erecting machine, in particular to an integrated bridge erecting machine for transporting three rows of tires on a rear vehicle. Background technique [0002] With the continuous development of my country's railways, the spans of prefabricated bridge piers erected on railway routes are getting larger and larger, and the length of erected concrete box girders is also increasing, and the requirements for bridge erecting machines are also getting higher and higher. For example: for a typical type of bridge erecting machine, as the length of the concrete box girder increases, the length of the main girder also increases, which will increase the length and weight of the bridge erecting machine. The rigidity of the main girder, carrying the girder through the tunnel, and the construction load and operability of the erected girder are all unfavorable. Contents of the invention [0003] The invention solves the deficiencies...
