The invention discloses a jacking cross beam for four-side eight-oil-cylinder synchronous jacking and a using method, and belongs to the technical field of crane jacking. The jacking cross beam comprises a frame type structure formed by connecting two half-frame cross beams and two I-shaped cross beams, and the two half-frame cross beams and the two I-shaped cross beams are symmetrical about the center line of the jacking cross beam. The half-frame cross beam comprises a main beam and two corner beams vertically connected to the two ends of the main beam, a cross beam connecting structure is arranged between the half-frame cross beam and the I-shaped cross beam, and the two ends of the main beam and the corner beams are each provided with a climbing claw and an oil cylinder connecting structure. The jacking device is higher in structural strength, eight-cylinder jacking can be carried out, and the jacking force is large; the oil cylinders and the climbing claws are close to the climbing frame main chord, the structural layout is more reasonable, the force borne by the jacking cross beam is more uniform and dispersed, the bending moment stress borne by the cross beam is reduced, the jacking requirement of the super-tonnage crane can be met, and stability and safety are higher.
本发明公开了一种四面八油缸同步顶升用顶升横梁及使用方法,属于起重机顶升技术领域;其包括由两个半框横梁以及两个I型横梁相互连接成的框式结构,两个半框横梁之间、两个I型横梁之间均关于顶升横梁中心线对称;半框横梁包括主梁以及垂直连接于主梁两端的两个转角梁,半框横梁和I型横梁之间设有横梁连接结构,主梁的两端以及各转角梁上均设置有一爬爪以及一油缸连接结构。本发明结构强度更高,可进行八缸顶升,顶升力大;油缸和爬爪靠近爬升架主弦,结构布局更加合理,顶升横梁受到的力更加均匀分散,降低横梁受到的弯矩应力,能够满足超大吨位起重机的顶升需求,稳定性及安全性更高。
