FIELD: physics. ^ SUBSTANCE: dynamometre has a torque sensor, a weighting device and a unit for connecting the sensor to the weighting device. The weighting device is in form of two support bearings, each with two rings. The support bearings are in line, the ring of one of them is in contact with the ring of the other and these rings are joined together, and the unit for connecting the sensor with the weighting device is on the joined bearing rings. The torque sensor can be made in form of a flexible rod, which grasps the joined bearing rings and is attached by one end to the said rings, and a dynamometre, connected to the second end of the rod. The dynamometre measures load on different types of mine working supports. ^ EFFECT: possibility of monitoring manifestation of rock pressure on places with combined support with high accuracy. ^ 2 cl, 2 dwg |
