Description

Technical Field

[0001] The utility model belongs to the technical field of outdoor hoisting of transformer substations, in particular to an outdoor hoisting device for a traction transformer substation. Background Art

[0002] When installing a traction substation outdoors, substation equipment such as lightning arresters, voltage transformers, insulators, etc. are generally installed on the top of concrete columns. Due to the small outdoor space of the substation, complex low-altitude lines, and diverse ground installations, cranes cannot enter, and scaffolding and other lifting equipment are difficult to deploy, so small special lifting equipment is often required for lifting.

[0003] Common lifting equipment is composed of a fixed rod on a column, a pulley fixing frame installed on the upper end, and an electric traction device installed at the lower end. However, there are some shortcomings when using it: 1. When fixing the columnar rod, it is necessary to use a clamp to fix the columnar rod on the concrete column, which is time-consuming. 2. When lifting the substation equipment, after vertical lifting, when installing the substation equipment on the top of the concrete column, it is necessary to use manpower to assist in docking and installation. High-altitude operations are unsafe and laborious. 3. When lifting and fixing the substation equipment, the binding method is usually adopted, which is very inefficient and needs to be improved.
