The invention provides a simple rail-type concrete transportation device which comprises an annular transportation rail and a transport cart arranged on the rail. The transport cart includes a hopper arranged on the upper portion of the transport cart. The simple rail-type concrete transportation device is characterized in that the transport cart further includes an underpan arranged on the lower portion of the transport cart, the front side and the rear side of the lower portion of the underpan in the rail direction are both provided with wheels, the underpan is provided with a rotary table connected with the underpan through a rotating shaft, the hopper is arranged on the upper portion of the rotary table, and the wheels on one side of the underpan are provided with limiting devices; the rail is formed by two monorail bodies which are arranged in parallel, rail beams are further arranged between the two monorail bodies, and rail supports are arranged on the lower portion of the rail. The simple rail-type concrete transportation device is light in weight and flexible to use, the multiple transport carts can be placed on the same rail, and the phenomenon of cart backing is avoided; besides, the simple rail-type concrete transportation device is especially applicable to continuous construction on working faces with formworks or reinforcing cage nets, manpower resource consumption is low, and application range is wide.
