The invention discloses a bridge lifting system and method, and belongs to the technical field of bridge construction. A bridge lifting system comprises a fixing frame, a winch with a steel wire rope is fixedly arranged in a bearing beam, the bridge lifting system further comprises a fixing base, a hook is fixedly arranged at the bottom of the fixing base, a rotating cavity is formed in the fixing base, a rotating shaft is rotationally arranged in the rotating cavity, an annular groove is formed in the outer wall of the rotating shaft, and the steel wire rope is wound around the annular groove; the nozzle is used for spraying lubricating liquid into the annular groove and is fixedly arranged on the inner wall of the rotating cavity, a liquid supply part is arranged in the fixed seat, and a heat dissipation assembly is arranged on the rotating shaft; the nozzle used for spraying lubricating liquid to the rotating shaft is arranged in the fixing base, the friction force between the steel wire rope and the rotating shaft can be reduced, friction heat generated on the rotating shaft can be reduced, heat dissipation of the rotating shaft is facilitated by spraying the lubricating liquid, the cooling effect can be further improved by arranging cooling fins on the rotating shaft, and the service life of the rotating shaft is prolonged. And long-term stable operation of the winch is ensured.
本发明公开了一种桥梁提升系统及提升方法,属于桥梁施工技术领域。一种桥梁提升系统,包括固定架,承载梁内固定设置有带有钢丝绳的卷扬机,还包括:固定座,固定座底部固定设置有挂钩,固定座内开设有转动腔,转动腔内转动设置有转轴,转轴外壁上开设有环形槽,且钢丝绳从环形槽内绕过;用于向环形槽内喷洒润滑液的喷嘴,固定设置在转动腔内壁,固定座内设置有供液部,且转轴上设置有散热组件;本发明通过在固定座内设置有用于向转轴喷洒润滑液的喷嘴,可以减少钢丝绳与转轴之间的摩擦力,从而可降低转轴上产生的摩擦热,经过喷洒润滑液,有助于转轴的散热,并且在转轴上设置有散热片,可以进一步提高散热效果,确保卷扬机长期稳定运行。
