The invention discloses a telescopic variable-pitch cable well cover plate lifting device. The device comprises a movable support; the supporting beam assembly comprises a main operation beam and an auxiliary operation beam, a fixed lifting hook is arranged on the auxiliary operation beam, and a movable lifting hook is arranged on the main operation beam; a plurality of first limiting holes are formed in the main operation beam, and a plurality of second limiting holes are formed in the auxiliary operation beam; the position of the auxiliary operation beam relative to the main operation beam is adjusted, the positions of the second limiting hole and the first limiting hole are kept to be matched, overlapped and aligned, and the limiting pin sequentially penetrates through the first limiting hole and the second limiting hole to lock and fix the auxiliary operation beam and the main operation beam. According to the telescopic variable-pitch cable well cover plate lifting device, folding storage of the lifting device is achieved, and storage and transportation of instruments are facilitated; the labor intensity and the efficiency of personnel are reduced, and the application range and the flexibility of the device are improved.

    本发明公开了一种可伸缩变距的电缆井盖板起落装置,包括:可移动支座;支撑梁组件,支撑梁组件包括:主操作梁和副操作梁,副操作梁上装设有定吊钩,主操作梁上装设有活动吊钩;以及装设在支撑梁组件一端部的操作把手,其中:主操作梁上设有多个第一限位孔,副操作梁上设有多个第二限位孔;调节副操作梁相对于主操作梁的位置,保持第二限位孔与第一限位孔的位置适配重合对齐,限位销依次穿过第一限位孔和第二限位孔将副操作梁和主操作梁锁紧固定。实施本发明的可伸缩变距的电缆井盖板起落装置,实现起落装置的折叠收纳,方便器械的存放和运输;降低了人员的劳动强度和效率,提高了装置的适用范围和灵活性。
