Bridge girder erection machine transformation and girder erection method capable of adapting to girder erection on large longitudinal slope
The invention discloses a bridge girder erection machine transformation and girder erection method capable of adapting to girder erection on a large longitudinal slope. By reducing the heights of the front supporting legs of the bridge girder erection machine and the lower guide beam thereof, the gradient of the bridge girder erection machine body and the lower guide beam is adjusted to be within 2%, the safety performance conditions of the bridge girder erection machine under the bridge girder erection operation working condition designed by an original factory are met, and safety control of the bridge girder erection machine in the bridge girder erection process is guaranteed. The transformed bridge girder erection machine can be independently heightened or lowered to adjust the longitudinal slopes of the bridge girder erection machine and the lower guide beam, the height difference of the front and rear support legs is adjusted, and compared with an original bridge girder erection machine, the lower sliding force caused by a large longitudinal slope is reduced, the safety accidents such as slope sliding, side sliding and overturning of the bridge girder erection machine are avoided, and the safety in the beam erection process is guaranteed; according to the bridge girder erection machine, original girder erection equipment is fully utilized, the depreciation cost of the equipment is reduced, a large amount of economic cost is saved, accurate adjustment of the girder erection gradient is achieved through the oil cylinder, the girder erection error is easier to control, and the girder erection quality is guaranteed.
本发明公开了一种可适应大纵坡架梁的架桥机改造及架梁方法。通过降低架桥机及其下导梁的前支腿高度，使架桥机机体及下导梁的坡度调整至2％以内，符合架桥机原厂设计架梁作业工况下的安全性能条件，保证其在架梁过程中的安全受控。本发明改造后的架桥机可作单独垫高或降低支腿处理，以调整架桥机及下导梁的纵坡，实现了前后支腿高差的调节，相比原架桥机，减少了因大纵坡引起的下滑力,避免造成架桥机发生溜坡、侧滑、倾覆等安全事故，保障了架梁过程中的安全；本发明架桥机使原有架梁设备得到充分运用，减少了设备折旧费，节约大量的经济成本，本发明架桥机通过油缸实现了架梁坡度的精准调节，架梁误差更容易得到控制，架梁质量得到保障。
