The tower crane jacking hanging plate device comprises jacking hanging plates, lug plates and pin shafts, the jacking hanging plates are hinged to the ends of a jacking cross beam, the jacking hanging plates are hinged to the left end and the right end of the jacking cross beam respectively, the lug plates are arranged on the edges of the jacking hanging plates and located in the overlapped area of the jacking hanging plates and the jacking cross beam, and the pin shafts are hinged to the lug plates. The pin shaft is arranged in the lug plate; according to the tower crane jacking hanging plate, it can be guaranteed that in the upward oil cylinder retracting process, the hanging plate can directly pass when approaching the step on the upper layer, an operator does not need to manually adjust the angle of the jacking hanging plate, mistaken hanging of the jacking hanging plate and the standard knot step can be avoided, and the working efficiency and safety of climbing can be improved; only two lug plates need to be added on the original basis and are connected through the pin shaft, the structure is simple, and operation is convenient and fast.
本发明提供的一种塔机顶升挂板装置,包括顶升挂板,耳板与销轴,顶升挂板与顶升横梁的端部铰接,且顶升横梁的左右两端分别铰接有顶升挂板,耳板设置在顶升挂板的边沿上,且位于顶升挂板与顶升横梁重叠的区域,销轴设置在耳板的内部;本发明可保证向上收油缸过程中,挂板接近上一层踏步时可直接通过,无需操作人员手动调节顶升挂板角度,可避免顶升挂板与标准节踏步误挂,能提高爬升的工作效率和安全性,这种塔机顶升挂板与普通顶升挂板相比,只需要在原基础上增加两块耳板,并通过销轴连接,结构简单,操作便捷。
