The invention discloses a resiliometer with a vertical auxiliary function. The resiliometer comprises a resiliometer body, the front end of the resiliometer body is provided with a vertical auxiliarymechanism, the vertical auxiliary mechanism comprises at least three groups of support legs, the support legs are arranged in an annular array with respect to the axis of the resiliometer body, and the support legs are of L-shaped structures; the supporting legs are rotationally mounted relative to the resiliometer body, the rotating axes of the supporting legs are located at the upper ends of thesupporting legs and perpendicular to the axis of the resiliometer body, all the supporting legs rotate synchronously, and when the supporting legs rotate, the included angle between the vertical edges of the supporting legs and the vertical plane is 0 degree-n, and n is larger than 0 degree and smaller than or equal to 15 degrees. According to the resiliometer with the vertical auxiliary function, the vertical auxiliary mechanism is arranged at the front end of the resiliometer body, so that the axis of the resiliometer is vertical to a test surface when an impact hammer in the resiliometer is excited.
Description
technical field [0001] The invention relates to the technical field of concrete testing instruments, in particular to a rebound rebound instrument with a vertical auxiliary function. Background technique [0002] When measuring the rebound value of concrete strength, it is required that the axis of the rebound hammer should always be perpendicular to the concrete testing surface, and it should apply pressure slowly, read accurately, and reset quickly. This operation process is relatively fast, and the axis of the hammer may be inclined, so that the impact direction is not perpendicular to the test plane, resulting in inaccurate test results. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a rebound hammer with a vertical auxiliary function. By setting a vertical auxiliary mechanism at the front end of the rebound hammer body, it is ensured that when the impact hammer in the rebou...
