Detailed Description

The present invention will be further described with reference to the accompanying drawings and embodiments.

Please refer to fig. 1-3, wherein fig. 1 is a schematic structural diagram of a preferred embodiment of a single-person slump testing device according to the present invention; FIG. 2 is a schematic view of an assembled structure of the slump cone and the disk shown in FIG. 1; fig. 3 is a schematic view of the assembly structure of the base surface and the three guide rods shown in fig. 1. The slump test device of single operation includes: a slump cone 1; a base surface 2, the base surface 2 being disposed below the slump cone 1; the disc 11 is fixedly arranged at the bottom of the slump cone 1; the three U-shaped clamps 3 are arranged on the disc 11 and the base surface 2; the three guide rods 21 are welded with the base surface 2 into a whole, the three guide rods 21 are distributed in a rotational symmetry mode, the top ends of the three guide rods 21 extend to the upper portion of the disc 11, and the bottom ends of the three guide rods 21 extend to the lower portion of the base surface 2.

The bottom ends of the three guide rods 21 are all provided with lifting bolts 23 in a threaded manner, the bottom ends of the lifting bolts 23 are fixedly provided with foot pads 24, and when the ground is uneven, the lifting bolts 23 are rotated to enable the lifting bolts 23 to ascend or descend for a certain distance, so that the leveling purpose is achieved.

The top of the disc 11 is provided with three guide sliding holes, the three guide rods 21 respectively penetrate through the three guide sliding holes, the three guide rods 21 are respectively connected with the inner walls of the three guide sliding holes in a sliding mode, and after a concrete sample is loaded, the three guide rods 21 play a role in guiding in the process of upwards lifting the cylinder, so that deflection is prevented.
