摘要

An apparatus for preventing breakage of a power supply unit is disclosed. The disclosed apparatus for preventing breakage of a power supply unit comprises a power reel unit; a fixed frame; a moving unit; an elastic member; and a sensing member. The power reel unit is installed in the body unit of a consecutive unloading machine to be able to rotate, and winds a power supply cable. The fixed frame covers the power reel unit by being fixed in the body unit. The moving unit which comprises an inner space for the power cable to pass by is installed in the lower part of the power reel unit, and makes a support protruding upward enter the fixed frame and move up and down. The elastic member is installed inside the fixed frame and supports the moving unit upward based on elastic force. The sensing member is installed in a downward passage of the moving unit, and senses the movement of the moving unit to generate a measurement signal.
