DEVICE FOR DETERMINING TECHNICAL STATE OF CONE CUTTER BIT Russian patent published in 2017 - IPC E21B12/00 G01M13/00 

FIELD: mining.

SUBSTANCE: device for determining the technical condition of a cone bit comprises the frame with the rotating body feeding mechanism fixed thereon, with the possibility to create load on the cone cutter to be diagnosed by means of the disc for the cone cutter rotation, the electric motor and the step speed control pulleys, the base frame for installing the cone cutter bit thereon, with the ability to fix a vibration sensor on its feet. The device is additionally provided with a removable cartridge for installing the cone cutter bit with the possibility of rotation around its own axis, mounted on the movable platform, with the possibility of moving in a horizontal plane via a handle mounted on the feeding worm gear mechanism shaft and the movable frame loaded by the handle mounted on the feeding shaft, the frequency converter of smooth lectrical motor speed regulation and the signal processing unit, both arranged on the frame, interconnected with the sensor for measuring the cutter rotation speed and the vibration sensor, the disc pad with a slot and a high-precision optical distance-measuring sensor. The disc pad is adapted to be fitted on the rotating body, and is fixed by the feeding mechanism in a vertical plane, and the optical distance-measuring sensor is mounted in the disc pad slot with the possibility of moving the sensor along the slot from the disk pad edge to its center.

EFFECT: improving the accuracy in determining the technical state of a cone cutter bit.
