The present invention relates to a stage driving apparatus and, more specifically, to a stage driving apparatus comprising; a base; a drive motor which is installed on a top of the base; a reducer which is installed at a lower part of the drive motor and is rotated by receiving the power of the drive motor; a wire drum which is connected to the reducer and moves stage equipment up and down by rolling or unfolding a wire rope connected to the stage equipment; and a guide pulley which is equipped at an upper part of the stage equipment in order to connect the wire rope rolled around the wire drum to the stage equipment by guiding the wire rope. The stage driving apparatus with an impact reduction member comprises: an impact absorption drum which is installed at a lower part of the rear of the wire drum; a guide rail which is arranged on both ends of a rotary shaft of the impact absorption drum; an oil pressure shock absorber which allows one side to be fixed on the base, allows the other side to be combined with the rotary shaft of the impact absorption drum and is equipped with a spring in order to move the impact absorption drum forward and backward; and a coupler which allows one side to be combined with the rotary shaft of the impact absorption drum and allows the other side to be combined to the guide rail in order to be moved. The wire rope rolled around the wire drum is installed to be connected to the stage equipment by being guided to the impact absorption drum and guide pulley. The oil pressure shock absorber reduces impact while being moved forward and backward along the guide rail when the impact absorption drum is moved forward and backward by impact generated by the weight of the stage equipment in case the wire rope is rolled or unfolded in order to move the stage equipment up and down. |
