Sliding device for ultra-wide separated steel box girder of extra-large cable-stayed bridge
The invention discloses a sliding device for an ultra-wide separated steel box girder of an extra-large cable-stayed bridge. The sliding device is characterized by comprising a supporting structure, a steel longitudinal beam, sliding shoes and shelving piers, the sliding shoe comprises a steel rail, a jacking oil cylinder, a lateral oil cylinder, a distribution beam, a pushing oil cylinder and a rail clamping device. The jacking oil cylinder and the lateral oil cylinder are fixedly arranged on the sliding shoe through a support. The lateral oil cylinders are arranged on the two sides of the jacking oil cylinder and are perpendicular to the jacking oil cylinder. The pushing oil cylinder is obliquely arranged on one outer side of the sliding shoe and is fixedly connected with the sliding shoe; the rail clamping device is arranged at the top end of the pushing oil cylinder and is fixedly connected with the push rod; and the distribution beam is arranged on the jacking oil cylinder. Compared with the prior art, the device has the advantages that the structure is simple, efficient, accurate, safe and synchronous sliding erection of the ultra-wide separation type steel box girder can be achieved, labor intensity is low, and the device is economical, efficient and safe and has good application prospects.
本发明公开了一种特大斜拉桥超宽分离式钢箱梁的滑移装置，其特点是该滑移装置包括：支撑结构、钢纵梁、滑靴和搁置墩；所述滑靴包括：钢轨、顶升油缸、侧向油缸、分配梁、顶推油缸和夹轨器；所述顶升油缸和侧向油缸由支架固定设置在滑靴上；所述侧向油缸设置在顶升油缸的两侧，且与顶升油缸为垂直设置；所述顶推油缸斜向设置在滑靴的一外侧，且与滑靴为固定连接；所述夹轨器设置在顶推油缸的顶端，且与推杆为固定连接；所述分配梁设置在顶升油缸上。本发明与现有技术相比具有结构简单，可实现超宽分离式钢箱梁高效、精确、安全、同步滑移架设，劳动强度低，经济、高效、安全，具有良好的应用前景。
