Cylindrical lifting machine

The utility model relates to a lifting auxiliary tool and in particular relates to a cylindrical lifting machine for lifting electric poles and devices which are used in a power line and various construction sites in the industrial field. According to the technical scheme, the cylindrical lifting machine comprises a lifting base, lifting blocks, lifting brackets, a pull rod, a hydraulic telescopic mechanism, an adsorption block, a hydraulic control unit and a rotation shaft, wherein a connection rod is connected with two lifting brackets through a rotation shaft; the tail ends of the lifting brackets are respectively connected with the lifting blocks; the lifting blocks are fixed on the lifting base and connected through the hydraulic telescopic mechanism; the adsorption block is symmetrically fixed on the inner side of the lifting base; the hydraulic telescopic mechanism is connected with the hydraulic control unit. The cylindrical lifting machine has the beneficial effects that the working efficiency for lifting the electric poles and devices in the sites can be effectively improved, the labor intensity of workers can also be greatly reduced; especially, the safety coefficient of site work is increased, and the cost is low.
