The invention discloses a high-altitude overhaul weight lifting improved device which comprises a fixing assembly which comprises a support and a bent column, a rotating assembly which is arranged in the fixing assembly and comprises a rotating column and a translation blocking column, a linkage assembly which is arranged on the two sides of the fixing assembly and comprises a first connecting rod and a second connecting rod, and a centrifugal assembly. The ratchet assembly is arranged between the rotating assembly and the linkage assembly and comprises a ratchet disc and a ratchet column. According to the device, under cooperation of the fixing assembly, the rotating assembly, the linkage assembly and the centrifugal assembly, hovering can be achieved when the hand is loosened when a heavy object is lifted, hovering cannot be achieved when the heavy object slowly descends, and hovering can be achieved when the hand is loosened when the heavy object slowly descends, so that the slow descending function of the device is not affected while the hovering and anti-falling functions are achieved; the safety during heavy object lifting is greatly improved, a large amount of manpower is saved, and unnecessary strength consumption is avoided.
本发明公开了一种高空检修重物升降改进装置,其中有固定组件,包括支架和弯柱,还有转动组件,设置于固定组件内部,包括转动柱和平动档柱,还有联动组件,设置于固定组件两侧,包括一号连杆和二号连杆,还有离心组件,设置于转动组件和联动组件之间,包括棘盘和棘柱。本发明装置在固定组件、转动组件、联动组件和离心组件的配合下,我方发明可以做到提升重物时松手会悬停,缓降重物时不会悬停,缓降重物时松手又会悬停,这样就拥有悬停、防坠的功能的同时不影响装置缓降的功能,大大提高了提升重物时的安全性,并节省了大量的人力,避免了不必要的力气消耗。
