The invention discloses a self-stabilizing double-rocker-arm hoisting and lifting device for mounting of a high-rise tower, and relates to the technical field of mounting of high-rise towers. The self-stabilizing double-rocker-arm hoisting and lifting device for mounting the tall tower comprises a base, a hydraulic telescopic rod is arranged at the top end of the base, a hydraulic telescopic arm is fixedly connected to the side wall of the top end of the hydraulic telescopic rod, reinforcing ribs are arranged on the hydraulic telescopic arm and used for conducting auxiliary fixing on the hydraulic telescopic arm, and a hoisting mechanism is arranged on the hydraulic telescopic arm; the hoisting mechanism comprises a worm gear, a ratchet wheel and a fixing ring. The ratchet wheel is used for limiting the auxiliary cable in a one-way mode, so that the auxiliary cable is taken up through the torsion spring during lifting, and after the main cable is broken, the auxiliary cable cannot be paid off through one-way limiting of the ratchet wheel, so that a lifted object can be limited; and personnel casualties caused by falling of the main cable from the air to the ground after the main cable is broken are prevented, so that the safety of workers can be ensured.
本发明公开了一种高耸塔架安装用自稳定双摇臂吊装提升装置,涉及高耸塔架安装技术领域。该高耸塔架安装用自稳定双摇臂吊装提升装置,包括底座,底座的顶端设置有液压伸缩杆,液压伸缩杆的顶端侧壁固定连接有液压伸缩臂,液压伸缩臂上设置有加强筋用于对液压伸缩臂进行辅助固定,液压伸缩臂上设置有吊装机构,所述吊装机构包括:蜗轮、棘轮和固定环。通过棘轮对辅助缆索的单向限位,使其在提升时,通过扭簧对辅助缆索进收线,而在主缆索发生断裂的情况后,通过棘轮的单向限位,使辅助缆索无法放线,从而能够对吊装的物体进行限位,防止其在主缆索断裂后从空中掉落到地面造成人员的伤亡,从而能够保证工作人员的安全。
