Abstract
The utility model relates to the technical field of self-compacting concrete, in particular to a self-compacting concrete slump expansion degree automatic testing device which comprises a base, a measuring mechanism for measuring concrete slump expansion degree is arranged on the upper surface of the base, and a limiting mechanism is arranged in the base. A third motor and a plurality of supporting rods are fixed to the upper surface of the base, and a top plate is fixed to the upper surfaces of the multiple supporting rods. According to the automatic testing device for the slump expansion degree of the self-compacting concrete, an electric push rod drives a measuring rod to move together with a height measuring instrument, a first motor drives a rotating rod and two first bevel gears to rotate together, and the first bevel gears drive a second bevel gear and a first threaded rod to rotate together; the two first threaded rods drive the moving block, the measuring rod and the height measuring instrument to move together, and after the measuring rod is attached to the top of concrete, the slump expansion degree is obtained through the numerical value measured by the height measuring instrument and the height of the slump cylinder.
