The tower crane step changing device comprises a step changing frame and a step changing swing rod, the step changing frame comprises two supporting arms and a connecting cross beam connected with the two supporting arms, the upper ends of the two supporting arms are hinged to an upper straight web member of a climbing frame, and the lower ends of the two supporting arms are hinged to a lower straight web member of the climbing frame. Clamping openings corresponding to steps on a tower crane standard knot are formed in the lower ends of the step changing swing rods, and the upper ends of the step changing swing rods are hinged to the upper straight web members and used for pushing or pulling the connecting cross beams under the condition that force is applied to the lower ends. And compared with the scheme of directly controlling the step changing frame, the operation process is more labor-saving, the heavy step changing frame can be operated to be hung on the step or separated from the step by a single person, and the step changing efficiency is effectively improved.

    本发明公开一种塔机换步装置及塔机,塔机换步装置包括换步架和换步摆杆,换步架包括两个支撑臂和连接两个支撑臂的连接横梁,两个支撑臂的上端均铰接于爬升架的上直腹杆上,并且下端均形成有与塔机标准节上的踏步对应的卡装口,换步摆杆上端铰接于上直腹杆上,并用于在施力于下端的情况下推动或拉动连接横梁。则操作人员通过换步摆杆带动整个换步架进行摆转,以实现将换步架挂入踏步或脱出踏步的操作,相较于直接控制换步架的方案,操作过程更加省力,即使是单人也能操作重量较大的换步架挂入踏步或脱出踏步,有效提高了换步效率。
