Small box girder transporting and hoisting method
The invention discloses a small box girder transporting and hoisting method which comprises the following steps: moving a rear support to a position 20-30m away from a rear support leg, moving two lifting trolleys to the top of the rear support to serve as a counterweight, moving a middle support leg to a position 1-2m away from a girder end and anchoring, retracting the rear support leg, enabling a rear support wheel to fall onto a support pad, enabling the middle support leg to be stressed on the lower surface of a sleeper beam of a front support leg, and enabling the middle support leg to be stressed on the lower surface of the sleeper beam of the front support leg. The front supporting leg is lowered to be jacked up and stressed by utilizing a reverse riding wheel mechanism on the middle supporting leg and a power mechanism of a rear riding wheel walking wheel box, and the front supporting leg is fixed, the rear supporting leg is jacked up and stressed after a main beam of the bridge girder erection machine is ensured to be horizontal, so that gradient adjustment is completed. By means of the concrete prefabricated plates, only the concrete prefabricated plates need to be laid, and efficiency is greatly improved. The mode of adjusting the cross slope through the steel sleeper is higher in safety, better in efficiency and better in overall stability, the danger degree of a traditional construction mode of adjusting the cross slope is higher, and follow-up treatment work is needed.
本发明公开了一种小箱梁运输吊装方法，包括以下步骤：将后托移至距后支腿20‑30m的位置，两个提升小车移至后托顶做配重，将中支腿移至梁端1‑2m的位置并锚固，收起后支腿，使后托轮下落至支垫上，在前支腿的枕梁的下表面，使中支腿受力，利用中支腿上的反托轮机构和后托轮行走轮箱的动力机构，下放前支腿顶起并使前支腿受力，在确保架桥机主梁水平后，将前支腿固定，后支腿顶起受力，坡度调整完成。本发明则通过混凝土预制板，只需铺设混凝土预制板即可，大大提升了效率。采用钢枕调整横坡的方式安全性更高，效率更好，整体稳定性更好传统横坡调整方式施工方式危险程度更高，而且还需后续处理工作。
