Abstract
A verification system for a large-scale weighing machine comprises at least four tension frameworks penetrating through a weighing platform hole preset on a weighing platform surface of the weighing machine, for connecting to a weighing platform foundation and being disposed perpendicular to the weighing platform surface, at least four self-adjusting loading-unloading load measuring devices disposed corresponding to the tension frameworks, and a constant-load control device connected with the loading-unloading mechanism and allows the loading-unloading mechanism to maintain constant applied load while loading. The self-adjusting loading-unloading load measuring devices includes a self-adjusting loading-unloading mechanism and a high-precision load measuring instrument adjacent to the top side of the loading-unloading mechanism. The high-precision load measuring instrument is at least three times larger than an accuracy of the weighing machine. The verification system has a rational structure and can greatly improve operating efficiency and safety and save cost.
