The invention relates to a calibration device for a concrete rebound tester, which includes a calibration bracket, on which a cylinder body positioning structure is arranged, and the cylinder body positioning structure includes a large top and a bottom small hole for positioning and matching with the cone tip part of the cylinder body. Conical positioning hole, the calibration bracket is provided with a bullet dry positioning support platform on the lower side of the cylinder positioning structure, and the top of the bullet dry positioning support platform is provided with a bottom of the bullet dry that is arranged concentrically with the tapered positioning hole. The positioning support groove is matched with the support and positioning. The calibration bracket is guided and moved in the up and down direction and is equipped with a slider. A dynamometer or a standard weight is connected to the slider, and a displacement measuring device for detecting the displacement distance of the slider is also arranged on the calibration bracket. The invention solves the time-consuming and labor-intensive technical problem that the concrete rebound hammer needs to be completely disassembled when calibrating the concrete rebound rebound meter in the prior art.
Description
technical field [0001] The invention relates to a calibration device for a concrete rebound tester in the field of instrument calibration. Background technique [0002] Concrete rebound tester is a testing equipment used to test the strength of various concrete structures such as building components and bridge components. Its structure is as disclosed in the Chinese patent CN110308062A "A Rebound Hammer for Engineering Supervision". It includes a cylinder and an impact hammer slidingly arranged inside it. A scale, a button and a button that slides along the direction of the scale are arranged on the inner wall of the cylinder. Pointer slider, the impact hammer is equipped with a center guide rod, one end of the center guide rod is covered with a bullet rod extending into the outside of the cylinder, the other end is fixed with a guide flange and firing mechanism, and the outside of the bullet rod is sleeved There is a spring for spring, which is a spring connected with the ...
