Abstract

The present invention discloses a lifting device for a substation and belongs to the technical field of electric tools. The device solves the technical problems in the prior art that the space between adjacent equipment in a substation is small and the equipment is inconvenient in lifting operation. The lifting device for the substation comprises a support. The bottom of the support is provided with a base. The base is connected with a power grid bracket in the substation. The top of the support is provided with a crane jib assembly. The crane jib assembly is connected with a fixed pulley and a lifting rope. The lifting rope is connected with a movable pulley. The movable pulley is provided with a lifting hook. The lifting rope sequentially comes round the movable pulley and the fixed pulley. The lifting device of the present invention is used for lifting and transporting to-be-maintained equipment in the substation.

Description

【Technical field】 [0001] The invention relates to a hoisting device for a substation. 【Background technique】 [0002] At present, with the long-term operation of equipment and the influence of the external environment, equipment failures and defects are increasing day by day. In order to ensure the reliable operation of the power grid, the work of replacing old equipment has become commonplace. However, both old equipment and new equipment are quite heavy, and the interval between adjacent equipment is narrow. In the prior art, the equipment is replaced and installed by hoisting by crane and carrying by scaffolding. However, it is difficult for a crane to pass through the small space of the substation; it is time-consuming and laborious to erect insulating scaffolding, and it is only feasible in substations with large intervals. 【Content of invention】 [0003] The technical problem solved by the invention is to provide a hoisting device for a substation, which facilitates...
