Crawling station-crossing method for bridge girder erection machine
The invention discloses a bridge girder erection machine crawling station-crossing method which comprises the following steps: S1, a first supporting body is arranged between an erected girder bridge section and a bridge pier of a to-be-erected girder section, a plurality of first supporting parts are arranged at the top of the first supporting body, and the first supporting parts are arranged at intervals in the length direction of the first supporting body; the top face of the first supporting part is flush with the top face of the erected beam bridge section, and a second supporting part is arranged at the top of a pier of the to-be-erected beam section; s2, the bridge erecting machine is located on the erected beam bridge section, a bridge pier of the beam section to be erected is located at the far end of the erected beam bridge section, and a first supporting leg, a second supporting leg, a third supporting leg and a fourth supporting leg are sequentially installed at the bottom of the bridge erecting machine from the near end to the far end; s3, the first supporting leg, the second supporting leg, the third supporting leg and the fourth supporting leg are alternately supported and stressed on the first supporting part and alternately move towards the far end through lifting and disengaging, and the bridge erecting machine is supported to longitudinally move and gradually move towards the far end; and S4, the bridge erecting machine moves to the position above the second supporting part, crawling station crossing of the bridge erecting machine is completed, and the transition efficiency of the bridge erecting machine is improved.
本发明公开了一种架桥机爬行过站方法，包括如下步骤：S1，在已架设梁桥段和待架梁段桥墩之间设置第一支撑体，第一支撑体的顶部设置多个第一支撑部，多个第一支撑部沿第一支撑体的长度方向间隔布置，第一支撑部的顶面与已架设梁桥段的顶面持平，在待架梁段桥墩顶部设置第二支撑部；S2，架桥机位于已架设梁桥段上，待架梁段桥墩位于已架设梁桥段的远端，在架桥机底部由近端至远端依次安装一号支腿、二号支腿、三号支腿和四号支腿；S3，一号支腿、二号支腿、三号支腿和四号支腿交替支撑受力在第一支撑部上，并交替通过上提脱空向远端移动运动，支撑架桥机纵移并逐渐向远端移动；S4，架桥机移动至第二支撑部上方，完成架桥机的爬行过站，提高了架桥机转场效率。
