FIELD: mechanics.
SUBSTANCE: proposed rod tiller for assembly and disassembly of downhole hydraulic motors relates to machine building. It incorporates a frame supporting fixed and moving hydraulic clamps. The said moving hydraulic clamp is furnished with a coupler, two power hydraulic cylinders to turn the said coupler and a hydraulic spinner. The fixed hydraulic clamp features a full-revolving coupler with clamping hydraulic cylinders to be cut in by a diaphragm actuator. The aforesaid full-revolving coupler is mechanically driven from several hydraulic motors.
EFFECT: rod tiller higher efficiency.
