Description

Improved device of resiliometer

Technical Field

The utility model relates to the technical field of concrete detection, in particular to an improved device of a rebound instrument.

Background

The basic principle of the resiliometer is that a spring is used for driving a heavy hammer, the heavy hammer impacts a striking rod vertically contacted with the concrete surface with constant kinetic energy, so that partial concrete is deformed and absorbs part of energy, the other part of energy is converted into the rebound kinetic energy of the heavy hammer, when the rebound kinetic energy is completely converted into potential energy, the heavy hammer rebound reaches the maximum distance, and the maximum rebound distance of the heavy hammer is displayed by the instrument in the name of rebound value (the ratio of the maximum rebound distance to the initial length of the spring).

Currently, the resiliometer on the market is mostly shown in the chinese patent with application number 202121799836.4, which includes: resiliometer shell, resiliometer host computer, bullet hit pole, drive assembly etc. but when using, the user holds the resiliometer main part and controls to hit the pole and prop against the concrete face, because the pole is thin to hit, the pole is hit with the concrete face's area of contact is little, rocks easily in the extrusion process to can't guarantee always to hit the straightness that hangs down of pole and concrete face, and then influence the detection effect.
