Abstract

The invention discloses a lifting device used for mounting large power equipment. The lifting device comprises a vehicle body and first hydraulic devices arranged on four corners of the outer side ofthe vehicle body; supporting bases are installed at the bottoms of the first hydraulic devices; a bracket is installed on the top of the vehicle body; a first traction mechanism and a first suspensionring are installed at the bottom of the right side of a suspension arm; a second steel wire is connected between the first traction mechanism and the first suspension ring; a rack is installed on a supporting board; a servo drive device is installed on the top of the rack; a guide block penetrates through the servo drive device and is in sliding connection with the rack through a sliding block; and the bottom of the guide block is connected with a second traction mechanism through a guide board. The lifting device improves the mounting efficiency, avoids multiple times of movement and hoisting lifting, and forms a simple lifting elevator structure, a worker can stand on the supporting board to be lifted and descended, mounting construction is convenient, the carrying pressure of high-altitude operation of the worker is reduced, and safety performance is improved.

Description

technical field [0001] The invention belongs to the technical field of electric equipment, in particular to a lifting device for installing large electric equipment.
