The invention discloses a tower crane climbing process anti-falling structure and method and a tower crane, the tower crane climbing process anti-falling structure comprises a climbing frame and a standard knot, the two sides of the climbing frame are each provided with a jacking pawl, the two sides of the standard knot are each provided with a step, the jacking pawls on the two sides are arranged on the corresponding steps respectively, and the jacking pawls on the two sides are arranged on the corresponding steps respectively. An anti-falling structure is installed between the climbing frame and the standard knot, a frame body of the climbing frame and steps on the standard knot are fixed together through the anti-falling structure, and when the jacking pawl loses efficacy, the anti-falling structure provides support for the jacking pawl. The anti-falling structure is simple, the using method is simple, and the risk of failure of the jacking pawl possibly occurring in the climbing and self-disassembling process of the tower crane is effectively avoided.
本发明公开了一种塔机爬升过程防脱结构、防脱方法及塔机,包括爬升架和标准节,所述爬升架两侧各设有一个顶升棘爪,所述标准节两侧各设有一个踏步,两侧的顶升棘爪分别布置在相应的踏步上,在所述爬升架和标准节之间安装有防脱结构,该防脱结构将爬升架的架体与标准节上的踏步固定在一起,在顶升棘爪失效时,防脱结构对顶升棘爪提供支撑。本发明中的防脱结构简洁,使用方法简单,有效规避塔机爬升、自拆过程中可能出现的顶升棘爪失效的风险。
