Essay

On basis of the set regularities in the systems of electromechanical rotation, of electrohydromechanical round-trips and approach of the well tube on a bottomhole there is developed a scientific concept of the automated drives construction in accordance with which is formed the mechanical characteristic with constant or with variable rigidness on a boring bit and limitation of transversal and torsional oscillations of the well tube, as well as of oscillations in a hydro-system and a wire rope polyspast system with the purpose of the increase resource of boring bit depending on the holed rigidity of rock. In accordance with the developed concept forced transversal oscillations of the well tube are confined by force of influencing on the signal of assignment of an intensity control device of the frequency of the rotation mechanism engine; own torsional oscillations and elastic oscillations in the hydro-system and wire rope polyspast system are confined by insertion of the additional fuzzy laws of control to the laws of the control of the loop classic regulators with simultaneous controlling and limitation on the permissible level of technological parameters: in the drive of the rotation there is a flux of mechanical power in the bottomhole; in the drive of round-trips and approach of the well tube on the bottomhole there is a linear speed of the approach of the well tube, the frequencies of the hydraulic engine rotation and pressure in the hydro system.
