Construction method of bridge girder erection machine and single-arm bridge girder erection machine
The invention relates to the technical field of bridge erection, in particular to a construction method of a bridge erecting machine and a single-arm bridge erecting machine. According to the construction method of the bridge girder erection machine, when a construction line is a small-curve road section, a front supporting leg assembly and a middle supporting leg assembly are folded, a first transverse moving mechanism is used for driving the front supporting leg assembly to transversely move towards the inside of a curve, a second transverse moving mechanism is used for driving the middle supporting leg assembly to transversely move towards the outside of the curve, and when the front supporting leg assembly and the middle supporting leg assembly are supported, the front supporting leg assembly and the middle supporting leg assembly are supported. The first transverse moving mechanism is used for driving the machine arm at the front supporting leg assembly to transversely move towards the inside of a curve, the second transverse moving mechanism is used for driving the machine arm at the middle supporting leg assembly to transversely move towards the outside of the curve, and the centers of the two ends of the machine arm can be adjusted to coincide with the centers of the first pier and the second pier. Therefore, when the small-curve girder erection is carried out, the bridge erecting machine does not need to be transformed, the small-curve hole passing process of the bridge erecting machine is simplified, the construction efficiency of the bridge erecting machine is improved, and the bridge erecting time of a small-curve road section is shortened.
本发明涉及桥梁架设技术领域，具体而言，涉及一种架桥机的施工方法及单臂架桥机。其中，一种架桥机的施工方法，当施工线路为小曲线路段时，收起前支腿总成和中支腿总成，利用第一横移机构驱动前支腿总成向曲线内横移，利用第二横移机构驱动中支腿总成向曲线外横移，支撑前支腿总成和中支腿总成时，利用第一横移机构驱动前支腿总成处的机臂向曲线内横移，利用第二横移机构驱动中支腿总成处的机臂向曲线外横移，可以将机臂的两端中心调节至与第一桥墩、第二桥墩的中心重合。由此，在进行小曲线架梁时，不需要对架桥机进行改造，简化了架桥机进行小曲线过孔的过程，有利于提高架桥机的施工效率，减少了小曲线路段桥梁架设的时间。
