A lifting device for a multifunctional cable well cover plate relates to the field of cranes and comprises a lifting unit, a lifting base frame and a lifting driver. The pipe sleeve is in lifting connection with the lifting base frame; the outer pipe is mounted on the pipe sleeve in a liftable manner; a rotating seat is mounted at the lower end of the outer pipe; the rotating part is rotatably mounted below the fixed part around the middle shaft; the plate limiting block is used for limiting a plate opening of the cable well cover plate; the outer pipe and the rotating seat are coaxially provided with a first inner cavity which is linearly communicated; moving wheels are mounted at the lower ends of the inner pipes; the inner pipe drives the moving wheel to extend out of or retract into the first inner cavity; the lifting driver is installed on the lifting base frame and used for driving the outer pipe or the inner pipe to move in a lifting mode. The output end of the pipe sleeve lifter is connected to the pipe sleeve and used for driving the pipe sleeve to ascend and descend and driving the plate limiting block to ascend and descend. According to the scheme, the lifting flexibility of the cable well cover plate can be improved, and the problem that the lifting efficiency is low due to the fact that an existing lifting device of the cable well cover plate cannot have the rotating function and the moving function at the same time is solved.

    一种多功能电缆井盖板的起落装置,涉及起重机领域,包括:起落单元、起落基架和升降驱动器;管套升降连接于起落基架;外管可升降地安装于管套;外管的下端安装有转座;转动部绕中轴可转动地安装于固定部的下方;板限位块用于限位在电缆井盖板的板口;外管及转座同轴设有直线连通的第一内腔;内管的下端安装有移动轮;内管带动移动轮伸出或收缩于第一内腔;升降驱动器安装于起落基架,升降驱动器用于驱动外管或内管升降移动;管套升降器的输出端连接于管套,用于驱动管套升降,带动板限位块升降。本方案可以提高了电缆井盖板的起落灵活性,解决了现有电缆井盖板的起落装置无法同时兼备转动和移动功能而导致起落效率低的问题。
