Bridge girder erection machine for erecting segmental assembled box girders
The invention discloses a bridge girder erection machine for erecting segmental assembled box girders, and relates to the technical field of bridge construction equipment. The device comprises a main beam frame, a beam hanging frame is slidably mounted in the main beam frame, uniformly distributed equipment boxes are fixedly mounted on the two sides of the main beam frame, and a hydraulic device is fixedly mounted on the lower surface of the beam hanging frame; an L-shaped rack plate and a bearing plate are driven to turn over downwards, so that the bearing plate is parallel to a front supporting seat, the bearing plate is driven to ascend and make contact with the lower end face of a pier, two abutting plates and two anti-skid pads are driven to turn over oppositely, and the opposite sides of the two anti-skid pads make contact with the two sides of the pier. The two abutting plates abut against the two sides of the bridge pier through the two anti-skid pads, so that auxiliary supporting and abutting after the front supporting base makes contact with the bridge pier are conveniently achieved, the stability between the front supporting base and the bridge pier is effectively improved, the situation that the front supporting base turns on one side is avoided, and meanwhile the safety coefficient of the bridge girder erection machine during operation is effectively improved.
本发明公开一种节段拼装箱梁架设用架桥机，涉及桥梁施工设备技术领域；而本发明包括主梁架，主梁架的内部滑动安装有吊梁架，主梁架的两侧均固定安装有均匀分布的设备箱，吊梁架的下表面固定安装有液压装置；通过驱动L型机架板和承托板向下翻转，使承托板与前支撑座呈平行状态，并驱动承托板上升，与桥墩的下端面接触，通过驱动两个抵紧板和两个防滑垫相向翻转，使两个防滑垫的相对侧和桥墩的两侧接触，两个抵紧板通过两个防滑垫与桥墩的两侧抵紧，从而方便的实现了前支撑座与桥墩接触后的辅助支撑及抵紧，进而有效的提高了前支撑座与桥墩之间的稳定性，避免前支撑座出现侧翻的情况，同时，有效的提高了架桥机作业时的安全系数。
