Floor double-rocker-arm derrick overturn-preventing slewing device
The invention belongs to the field of extra-high voltage power transmission construction tower assembling, and particularly relates to a floor double-rocker-arm derrick anti-overturning slewing gear, an upper seat component and a lower seat component are connected through a slewing support, the upper seat component comprises four support lugs, an upper seat and a disc-shaped cylinder, the upper seat is arranged on the upper seat, and the disc-shaped cylinder is arranged on the lower seat. The four supporting lugs are evenly distributed on the front side face and the rear side face of the upper base, the disc-shaped barrel is fixedly installed at the lower end of the upper base and connected with the slewing bearing, when abnormal unbalanced bias load occurs, transverse force deviating to the vertical direction occurs on the supporting lugs and the upper base, and when the transverse overturning force exceeds the load capable of being borne by the slewing bearing, the supporting lugs and the upper base are overturned by the upper base and the slewing bearing. The disc-shaped cylinder transmits bias force to the base section and the limiting wheel, the base section bears overturning force, the situation that under the abnormal transverse overturning force, after the slewing bearing is damaged, the whole upper base composed of the supporting lug, the upper base, the disc-shaped cylinder and the slewing bearing overturns is avoided, and serious unsafe events are avoided.
本发明属于特高压输电施工杆塔组立领域，尤其涉及一种落地双摇臂抱杆防倾覆回转装置，所述上座部件和下座部件通过回转支撑相连接，所述上座部件包括支耳、上座和盘状筒，所述支耳设置有四个，四个所述的支耳均布在上座前后两侧面，上座下端固定安装有盘状筒，盘状筒与回转支承相连接，在异常的不平衡偏置载荷出现时，在支耳，上座上，出现偏向于垂直方向的横向力，当这个横向倾覆力超过回转支承所能承受的载荷时，由上座，盘状筒将偏置力，传递到基座节、限位轮上，由基座节承担倾覆力，阻止了在异常的横向倾覆力下，回转支承破坏后，导致由支耳，上座，盘状筒，回转支承组成的上座的整体倾覆，阻止了严重不安全事件的发生。
