Rapid hole passing method for gantry type double-girder bridge girder erection machine
The invention provides a rapid hole passing method for a gantry type double-girder bridge girder erection machine. The rapid hole passing method comprises the steps that S1, the bridge girder erection machine and a girder transporting vehicle are hoisted to a bridge; s2, the bridge girder erection machine prepares a via hole; s3, the rear supporting legs are lifted, and the angles of the traveling wheels are driven to be matched with the tangential direction of the curve of the bridge; s4, the middle supporting leg is lifted to walk to the front end of the erected bridge along the main beam of the bridge erecting machine, and after the middle supporting leg is supported on the upper surface of the bridge, a steering locking mechanism at the lower end of the middle supporting leg is removed; s5, the front supporting legs are folded, the bridge erecting machine is driven by the rear supporting leg walking wheels to be driven along the bridge until the front supporting legs move to the position above the next pier, and the front supporting legs are riveted to the corresponding piers; and S6, the rear supporting legs are lifted, and the walking wheels are reset. The steering locking mechanism is arranged, the angle of the bridge erecting machine can be adjusted in the direction of a bridge by adjusting the angle of the walking wheels, and therefore the requirement for erecting a small-radius bridge is met, the bridge erecting difficulty is lowered, and the hole passing speed of the bridge erecting machine is increased.
本发明提供一种龙门式双主梁架桥机的快速过孔方法，包括：步骤S1，将架桥机和运梁车吊装上桥；步骤S2，架桥机准备过孔；步骤S3，提升后支腿并驱动行走轮角度与桥梁的曲线的切线方向相适配；步骤S4，起升中支腿，使中支腿沿架桥机主梁行走至已架设桥梁的前端，将中支腿支撑在桥梁上表面后，解除中支腿下端的转向锁定机构；步骤S5，收起前支腿，通过后支腿行走轮驱动架桥机沿桥梁驱动，直至前支腿移动至下一墩台上方，将前支腿铆钉在对应的墩体上；步骤S6，将后支腿提升并复位行走轮。设置转向锁定机构，通过行走轮的角度调整使架桥机可以沿桥梁走向进行角度调整，从而满足对小半径桥梁的架桥需求，降低架桥难度，提高架桥机过孔的速度。
