Snubbing coupling detector is an auto-detector used to detect tubing coupling motion state of snubbing workover rig. Install detector in blowout preventer when working; detector probe touches coupling when drilling pipe ascends or descends; transmit mechanical displacement into output signal of circuit electric quantity. When the circuit electric quantity received by detector increases, it connects sound-light alarm and automatically gives an alarm, so as to remind driller to install or dismantle oil pipe.
