AUTOMATED DEVICE FOR IMPACT DRILLING OF WELLS Russian patent published in 2022 - IPC E21B1/02 E21B44/00 B66D1/40 

FIELD: construction industry.

SUBSTANCE: invention relates to the field of construction, in particular to the technology of impact well drilling, and can be used to create automated control and measurement wells in nuclear and radiation-hazardous facilities. An automated device for impact drilling of wells is a single automated system containing a portable platform with an electric motor, a gearbox, electrically controlled electromagnetic couplings and a coil installed on it, a suspension unit through which a metal cable is thrown, connected at one end to a striker and the other to a coil, and a control unit. The transfer of the kinetic torque from the drive shaft to the coil shaft is carried out by means of an electrically controlled electromagnetic transfer clutch. The braking of coil rotation is realized by means of an electrically controlled electromagnetic brake clutch. At the upper end of the casing pipe, inside which the striker is located, there is a shock sensor made in the form of an accelerometer, making it possible to determine the moment when the striker reaches the striking pin and enable the electromagnetic coupling. The operation of the device elements is controlled remotely from the control unit. The lifting height of the tool is determined by the operating time of the electromagnetic transfer clutch, set by the operator on the timer built into the control unit. The lifting height of the tool above the face, set by the operator at the beginning of work, is maintained as the face deepens, and can also be adjusted by the operator without interrupting work.

EFFECT: invention provides an increase in the efficiency of the use of known devices and the expansion of their functionality.
