Abstract

The invention discloses a lifting method for installing large-scale power equipment, and the lifting method comprises the following steps: S1, a first motor and a second hydraulic device work to suspend a suspension arm; S2, a first hook at the end of a first wire rope is used to hang large electrical equipment accessory, a second hook at the end of a second wire rope is used to hang large electrical equipment accessories; S3, a third hydraulic device can be used to lift a support plate structure, and a worker can stand on a support plate to perform height lifting work; and S4, a frame structure arranged at the top of the support plate is used to control left-right adjustment of a second traction mechanism by a servo drive device, and the second traction mechanism is used for lifting a tool and a component for lifting movement. The lifting method improves the installation efficiency, avoids multiple times of movement and suspending and lifting of the device, and a simple lifting elevator structure is formed. The worker can stand on the support plate for lifting, the method is convenient for installation and construction, reduces the carrying pressure of the worker working at height, and improves the safety performance.

Description

technical field [0001] The invention relates to the technical field of power equipment, in particular to a lifting method for a lifting device used for installing large-scale power equipment. Background technique [0002] Power equipment mainly includes power generation equipment and power supply equipment. Power generation equipment is mainly power plant boilers, steam turbines, gas turbines, water turbines, generators, transformers, etc. Power supply equipment is mainly transmission lines of various voltage levels, transformers, contactors, etc. device and so on. [0003] In the installation process of large-scale electric equipment, the existing methods all adopt cranes to carry out lifting adjustment. Crane in the prior art has following several kinds: [0004] Chinese patent application CN200920041401.6 discloses a hydraulic crane for lifting and displacing power equipment installation, maintenance and other industry equipment and objects, such as figure 1 As shown, ...
