Hoisting device

The invention relates to a hoisting device which comprises an n-shaped frame, a cantilever, a hanging basket and a fixing mechanism. The cantilever is arranged on the top of the n-shaped frame. The hanging basket is arranged on the cantilever and can move up and down relative to the cantilever. The fixing mechanism comprises two supporting beams and two positioning assemblies. One ends of the two supporting beams are connected to the n-shaped frame. The supporting beams are provided with the positioning assemblies respectively. Each positioning assembly comprises a positioning frame, an adjusting piece and a connecting piece, wherein the positioning frame is connected to the corresponding supporting beam through the connecting piece, the adjusting piece penetrates through the positioning frame and can move relative to the positioning frame, and a capacitor frame can be fixed into the positioning frame by moving the adjusting piece. The hoisting device can be used for overhauling or replacing a capacitor. During work, the n-shaped frame is fixed, the capacitor frames are fixed into the positioning frames by moving the adjusting pieces, and therefore it is ensured that the hoisting device is stably installed; the capacitor to be overhauled or replaced is transported up and down through the hanging basket, and work efficiency and work safety are improved; the hoisting device is simple in structure and suitable for places with narrow spaces.
