| titleOfInvention | A kind of rotation driving of well drilling drill string and delivery device |
| abstract | The invention belongs to drilling technology field, more particularly to rotation driving and the delivery device of a kind of well drilling drill string, it includes drilling rod fixed mechanism, motor, push hydraulic stem, hollow drive shaft, drilling rod attachment structure, hydraulic stem and fixes support, drilling rod shaft, wherein motor is fixed in hydraulic stem fixation support by pushing hydraulic stem, the flexible of hydraulic stem can drive motor to move up and down, motor rotating shaft is hollow drive shaft, and hollow drive shaft can drive drilling rod shaft to rotate and move up and down by drilling rod fixed mechanism；Two drilling rod shafts are linked together by drilling rod attachment structure, and designed drilling rod attachment structure organically combines with drilling rod fixed mechanism, realize connection and the driving function of drilling rod.In addition, drilling rod bindiny mechanism is compact-sized, it can ensure that the diameter in junction is consistent with drilling rod shaft diameter, avoid destruction of the excessive drilling rod attachment structure to drilling well well face.Whole mechanism has certain practical function. |
