Abstract

The invention relates to mining. namely, drilling and coring tools. The juggling circuit is an increase in the core output and efficiency of the drilling process. The coring turbo-drill comprises a body of several sections connected in series with stator discs and hollow shaft with rotor discs. Hollow shafts are connected to each other by a frictional conical joint, and a removable core tube is placed inside the shafts with a drain valve and with a gripping head supported on the body. The stator disks are installed with a possibility of longitudinal displacement relative to the body and based on the rotor disks, while the stator disks are shaped not closed elastically deformable ring with an outer diameter greater than the inner diameter of corgie 2 silt

The purpose of the invention to increase the core yield and the efficiency of the drilling process

A kernney boron turbo-drill contains a nw Hi core of several series-connected sections 1 To sections I, a stator vice is placed 2. With a form of an open spring, formed from a ring with an outer diameter larger than the inner diameter of the housing. In section 1 there are hollow shafts 3 with rotor disks 4 Shafts 3 are kinematically connected to each other with another friction conical connection formed by means of shafts 5 and 6 of shaft 3. A removable core tube 7 is placed with a drain valve 8 and a gripping head 9 supported through a support 10 on the housing.

The disks of the stator 2 are mounted in the housing 1 with the possibility of longitudinal displacement relative to the housing and supported by the disks of the rotor 4 A drill head 1 1 is fixed at the lower end of the corps.

The coring turbodrill works in this way.

When pumping the working fluid through the coring turbo-drill, each disk of the stator 2 is pressed hydraulic to the DISC of the rotor 4. Couplings 5 and 6 are pressed against each other by the hydraulic axial load from the pressure drop on the disks of the stator and the rotor, as well as the weight of the shafts. Shafts 3 the drilling head 11 is rotated and the core is drilled out, which goes into the core receiver 7 of the core receiver. Hydraulic loading. as well as friction forces in the contact of the stator discs with the case, prevent relative axial movement of the sleeves 5 and 6 while drilling at a constant contact. Prevents the possibility of the working fluid moving through the gap between the couplings and further
