DEVICE FOR MEASURING ROCK STRENGTH

摘要

The utility model relates to mining and is designed to measure the strength properties of rocks by the express method directly in the place of their occurrence. The technical result is to expand the field of application of the device in determining the strength of rocks. The specified technical result is achieved by the fact that the device for measuring the strength of rocks containing a body with a handle, a torque spring, a torque spring retainer, a rod with an indenter, a screw cap with a cap for assembling a torque spring and a rod with an indenter in the body, a device for measuring the amount of movement of the rod, according to the claimed technical solution, it is equipped with an additional indenter, a torque spring and a lock located in the hollow handle of the housing, and each indenter is made elongated with the ability to exit through the guide sleeve outside the housing and is equipped with a cylindrical seating surface with a shoulder for frictional locking in the bore The distance of the stem, working with the corresponding indenter torque spring and retainer. 2 ill.
