PURPOSE:To make it possible to convey large massive objects easily without any mechanical damage on each part of a device by connecting the multiple members of bellows type elastic expansion body and forcing each of said expansion bodies to expand and contract along a guide by the successive operations or respective expansion jacks. CONSTITUTION:Elastic expansion bodies 1A, 1C are contracted, another elastic expansion body 1B is expanded, liquid to be conveyed is provided from left side toward the arrow direction, and a closed suction inlet P is fully filled with said liquid. Next the contracted state of said elastic expansion body 1A is changed to the cylindrically expanded state by the action of a jack 3a, so a vacuum state is formed by the expansion of volume of said body, and said liquid to be conveyed is sucked into said elastic expansion body 1A through said suction inlet P which is opened by the suction power generated with said expansion of volume. At the same time, a jack 3b is contracted and the cylindrically expanded state of said elastic expansion body 1B is changed to the contracted state. The liquid to be conveyed in said elastic expansion body 1B is conveyed to the right direction with the action of an inner conical surface, said elastic expansion body 1c is expanded cylindrically by the expansion of a jack 3c to receive the liquid to be conveyed from the adjacent expansion body 1B, and said liquid is transferred toward the right arrow direction. |
