Abstract
Disclosed is a hydraulic buffer energy storage device for an over-discharged hoist skip in a vertical shaft. The hydraulic buffer energy storage device for an over-discharged hoist skip in a vertical shaft comprises a vertical shaft, where a hoist skip is hung on an inner side of the vertical shaft, and a hydraulic buffer mechanism is arranged on the inner side of the vertical shaft; the hoist skip is positioned above the hydraulic buffer mechanism; the hydraulic buffer mechanism is communicated with an accumulator group, a pressure relief part and an oil replenishing part through an oil pipeline; the accumulator group is communicated with an energy storage part through an oil pipeline; the energy storage part, the pressure relief part and the oil replenishing part are respectively communicated with an oil tank through oil pipelines, the hydraulic buffer mechanism is connected with a displacement sensor.
