Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, and particularly relates to a new type of rebound hammer calibration device. Background Technique

[0002] A rebound hammer is a device that uses a spring to drive a striker. The striker impacts the concrete surface through a striker rod. The concrete surface undergoes instantaneous elastic deformation to absorb energy, and the striker rebounds. The hardness of the concrete is characterized by the energy loss. The principle used is that the harder the concrete, the less energy is absorbed by the elastic deformation of the concrete, and thus the less energy is lost during the impact of the striker.

[0003] In order to improve the measurement accuracy of the rebound hammer, a calibration device needs to be used to calibrate the rebound hammer regularly. However, the existing calibration devices are usually used for rebound hammers of the same specification or with a small specification difference, and their application range is small.
