Installation-detachment support for transformer

The invention relates to electrical equipment, that is, an installation-detachment support for a transformer. The installation-detachment support comprises a three-dimensional support (1) composed of vertical columns (2) and a cross beam, and is characterized in that a longitudinal slide way (4) is arranged on the support (1) along the two sides; a longitudinal tackle (5) is arranged on the longitudinal slide way (4); the longitudinal tackle (5) is provided with a transversal slide way (6); a transversal tackle (7) is assembled on the transversal slide way (6); and a winch is installed on the transversal tackle (7). The installation-detachment support has the beneficial effects of being capable of rapidly completing installation and detachment for the transformer, less in occupied space, free from risk of electric shock, fast in hoisting speed, safe and reliable, simple in structure and convenient to operate, and is expected to replace a crane and a chain block as preferred equipment for construction and maintenance for a transformer platform.
