The invention discloses a tower crane jacking cross beam anti-falling mechanism, and relates to the technical field of tower cranes, the tower crane jacking cross beam anti-falling mechanism comprises two jacking cross beams and a jacking hydraulic cylinder connected between the two jacking cross beams, and the two sides of each jacking cross beam are each provided with a supporting pin shaft and an anti-falling pin shaft; jacking steps matched with the supporting pin shafts and the anti-disengaging pin shafts are arranged on the standard knots, an anti-disengaging hydraulic cylinder is arranged on one jacking cross beam or one jacking hydraulic cylinder, adjusting mechanisms used for controlling the matching state of the supporting pin shafts and the anti-disengaging pin shafts with the jacking steps are arranged at the two ends of the jacking cross beams, and the adjusting mechanisms are driven by the anti-disengaging hydraulic cylinders. According to the jacking device, the anti-falling hydraulic cylinders and the adjusting mechanisms are arranged, the matching state between the supporting pin shafts and the anti-falling pin shafts on the two jacking cross beams and the jacking pedals is controlled through the adjusting mechanisms, labor is saved, and efficiency is also improved; and the safety of the climbing frame in the climbing process is improved by controlling the anti-falling pin shaft.

    本发明公开了一种塔式起重机顶升横梁防脱机构,涉及塔式起重机技术领域,包括两个顶升横梁和连接在两个顶升横梁之间的顶升液压缸,顶升横梁的两侧均设置有支撑销轴和防脱销轴,标准节上设置有与支撑销轴和防脱销轴配合的顶升踏步,其中一个顶升横梁或顶升液压缸上设置有防脱液压缸,顶升横梁的两端均设置有用于控制支撑销轴和防脱销轴与顶升踏步配合状态的调节机构,调节机构由防脱液压缸驱动。本发明通过设置防脱液压缸和调节机构,通过调节机构控制两个顶升横梁上的支撑销轴和防脱销轴与顶升踏步之间的配合状态,节约了人工,也提高了效率;对防脱销轴的控制,提高了爬架在爬升过程中的安全性。
