Problems solved by technology

The speed of urban rail transit is lower than that of high-speed rail, and the corresponding radius of curvature is also reduced and much, and some sections are even smaller than m, which makes the equipment for erecting high-speed rail beams unable to meet the erection of urban rail beams.

Abstract

The invention belongs to the field of bridge erection, particularly relating to a small-curve bridge erecting machine for bridge erection for railways. The bridge erecting machine for bridge erection comprises a girder assembly, a cantilever beam arranged on the front end of the girder assembly and a lower guide beam assembly arranged on the lower part of the girder assembly, wherein an assistant trolley is arranged on the cantilever beam; the front end of the girder assembly is provided with a front landing leg assembly, an assistant landing leg is arranged between the girder assembly and the lower guide beam assembly, the rear part of the girder assembly is provided with a rear landing leg assembly, and the upper part of the girder assembly is provided with a hoisting trolley and a winch connected with the hoisting trolley. The invention has high bridge erection efficiency and high hole passing speed; low guide beam causes that the guide beam can bear bigger yawing force to ensure that the bridge erecting machine is safer to pass through the hole; large assistant crown block shift amount can erect the beam with smaller curvature radius; a rear landing leg running slide plate can reduce bridge erecting machine running resistance and prevent the running mechanism from being damaged.

Description

technical field [0001] The invention belongs to the field of bridge erecting, and in particular relates to a bridge erecting machine for small curved railway bridges. Background technique [0002] With the rapid development of high-speed rail, urban rail transit has also developed rapidly. The speed of urban rail transit is lower than that of high-speed rail, and the corresponding radius of curvature is also reduced and much, and some sections are even smaller than m, which makes the equipment for erecting high-speed rail beams unable to meet the erection of urban rail beams. In response to this situation, our company invented a bridge erecting machine capable of erecting line girders with small curvature radius through partial transformation of high-speed railway bridge machines. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a bridge erecting machine which is convenient for passing hol...
