The invention discloses a spinner assembly of an iron driller. The spinner assembly capable of spinning a drill stem comprises a spinner column, a crossbeam sliding plate, a spinner bracket, a horizontal cylinder, a wedge plate, a clamping movable arm, a hydraulic motor, a roller, a reset spring, a front-and-back floating adjusting device and an up-and-down floating device. The spinner bracket is capable of moving frontward and backward along the crossbeam sliding plate; a piston rod of the horizontal cylinder fixed on the spinner bracket is connected with the wedge plate through a pin shaft; a middle hinge point of the clamping movable arm capable of rotating around the middle hinge point is connected with the spinner bracket through the pin shaft; by means of spring force, tangent rollers arranged at the back end of the clamping movable arm are always contacted with the sides of the wedge plate; spinner rollers arranged at the front end of the clamping movable arm are driven by the hydraulic motor; the telescopic movement of the horizontal cylinder drives the wedge plate to move back and forth; when the wedge plate is extending out, the drill stem is clamped by the rotation of the clamping movable arm; after finishing the spinning operation, the wedge plate is retracted, and the clamping movable arm is reset to the original position through the reset spring positioned above the wedge plate so as to release the drill stem.
Description
technical field [0001] The invention relates to a wellhead automation equipment in the petroleum drilling industry, in particular to an iron driller's turnbuckle device. Background technique [0002] The iron driller's turnbuckle device is a kind of wellhead automation equipment, which can quickly connect the two drilling tools after the preparation work of the two drilling tools to be connected is completed; Turnbuckle work. At present, many turnbuckle equipment, such as hydraulic tongs, etc., require manual operation, and the structure is complex and the effect is poor. These factors directly affect the work efficiency. Contents of the invention [0003] The object of the present invention is to provide an iron driller's turnbuckle device with simple structure, stable operation, good force transmission effect, reliable force state, convenient floating adjustment and strong adaptability to the position of the drill pipe. [0004] The invention is composed of a turnbuckl...
