Description

Technical Field

[0001] The utility model relates to the technical field of rebound hammers, in particular to a rebound hammer calibration device. 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). The rebound hammer is calibrated through a calibration device when in use to improve the measurement accuracy of the rebound hammer.

[0003] After searching the Chinese patent "A concrete rebound test hammer calibration device", the publication number is "CN217006829U". This patent fixes the rebound test hammer shell by a rebound test hammer fixing assembly, changes the elongation distance of the impact rod by moving the impact rod clamping assembly, detects the tension on the impact rod by the impact rod tension measuring assembly, and calibrates the impact tension spring inside the rebound test hammer according to the elongation distance of the impact rod and the corresponding tension value. It has a simple structure and is easy to operate. However, the device is prone to tilt when calibrating the rebound test hammer, which makes it inconvenient to vertically calibrate the rebound test hammer, affecting the calibration effect of the rebound test hammer.

[0004] Therefore, a rebound hammer calibration device is proposed to solve the above problems. Utility Model Content
