Abstract

The invention discloses a bridge erecting machine. The bridge erecting machine comprises a main girder, a large vehicle track, a rear landing leg, a front landing leg, an auxiliary landing leg and hoisting mechanisms, wherein one end of the large vehicle track is arranged on a first supporting pile; the rear landing leg is arranged at the rear part of the main girder and is arranged on the large vehicle track, and jacking horizontal movement supporting assemblies are arranged on the rear landing leg; one end of the front landing leg is arranged on a second supporting pile, the other end of the front landing leg is arranged on the main girder, and a horizontal movement mechanism is arranged on the front landing leg; a bended supporting girder is connected to the front end of the main girder, and the bended supporting girder extends to the inner side of the main girder; one end of the auxiliary landing leg is arranged on the bended supporting girder, and the other end of the auxiliary landing leg is arranged on a third supporting pile. According to the bridge erecting machine, the bended supporting girder is additionally arranged at the end of the main girder, so that the stability and the reliability are improved; the hoisting mechanism can operate to the front end of the bended supporting girder along the main girder, so that the moving range of a lifting girder piece is enlarged, and a bridge is convenient to erect.

Description

technical field [0001] The invention relates to road and bridge equipment, in particular to a bridge erecting machine. Background technique [0002] The bridge erecting machine is the equipment that places the prefabricated girders on the prefabricated bridge piers. Bridge erecting machines fall into the category of cranes because their main function is to lift beams, transport them into position and then lower them down. [0003] As we all know, most of the bridge erecting machines work at high altitudes, so their stability and reliability are important indicators to measure the performance of the bridge erecting machines. The lifting mechanism used to lift the girder is limited in its travel along the main girder, which affects its normal use in some specific environments. Contents of the invention [0004] The object of the present invention is to provide a bridge erecting machine, which has the characteristics of high stability and reliability and unlimited movement ...
