Transverse bridge girder erection machine and use method
The invention relates to a transversely-arranged bridge girder erection machine and a using method. The using method comprises the steps that the transversely-arranged bridge girder erection machine is assembled, prefabricated beams are symmetrically and synchronously hoisted on the two sides of the transversely-arranged bridge girder erection machine, and the transversely-arranged bridge girder erection machine moves longitudinally and is disassembled. The method has the beneficial effects that compared with a traditional process, the width of the bridge girder erection machine is widened, so that four crane carriages can be arranged, while the traditional bridge girder erection machine is only provided with two crane carriages, two precast beams can be synchronously erected at a time, and the erection efficiency is doubled; a beam lifting station does not need to be arranged, a road does not need to be closed for beam hanging, and the precast beam erecting operation can be efficiently completed under the condition that the road is smooth; and high-low hoisting is replaced, the hoisting step is simplified, and the beam hoisting efficiency under the condition that the length of the precast beam is limited by the cover beam is remarkably improved.
本发明涉及一种横置架桥机及使用方法，包括步骤：横置架桥机组装、横置架桥机两侧对称同步吊装预制梁、横置架桥机纵向移位和横置架桥机拆除。本发明的有益效果是：与传统工艺相比，本发明拓宽了架桥机的宽度，从而可以布设四台起重小车，而传统架桥机只有两台起重小车，故本发明可一次性同步架设两根预制梁，使得架设效率翻倍；且不需要设置提梁站，也不需要封闭道路吊梁，能够在保证道路通顺的情况下，高效完成预制梁架设作业；取代高低吊，简化了吊装步骤，显著提升了预制梁长度收到盖梁限制的情况下的吊梁效率。
