Description

Technical Field

[0001] The utility model relates to the technical field of rebound hammers, in particular to a vertical calibration component of a rebound hammer for supervision. Background Art

[0002] The basic principle of the rebound hammer is to use a spring to drive a heavy hammer. The heavy hammer hits the impact rod in vertical contact with the concrete surface with constant kinetic energy, causing the local concrete to deform and absorb part of the energy, and the other part of the 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 rebounds to the maximum distance. The instrument displays the maximum rebound distance of the heavy hammer in the name of the rebound value (the ratio of the maximum rebound distance to the initial length of the spring).

[0003] At present, a Chinese patent with publication number CN210293961U discloses a vertical calibration device for a rebound hammer. The utility model provides a vertical calibration device structure for a rebound hammer. A three-legged supporting column is designed. The supporting column includes a main column and a telescopic column. The length of the supporting column can be adjusted. At the same time, three fixing clamps are designed to clamp the rebound hammer. The relative position of the rebound hammer and the disc can be adjusted by adjusting the bolts and nuts. Through the cooperation of the fixing clamps and the supporting columns, a stable supporting role is played during detection, which effectively prevents the rebound hammer from shaking during the impact process, ensures that the axis of the rebound hammer is perpendicular to the structural surface of the concrete, and improves the detection accuracy.

[0004] During the use of the rebound hammer, it is necessary to keep the rebound hammer in a vertical state at all times. After the rebound hammer falls, it rebounds through the internal spring. If the rebound hammer is tilted, it is not convenient for calibration. During use, the limit plate needs to be stabilized for easy use. Utility Model Content
