Abstract
The invention discloses a safety drilling control device. The safety drilling control device is characterized in that safety bolts are powerfully adsorbed on a lift sub when the safety bolts are inserted into lugs; even if the lift sub is overturned, the lift sub does not fall off in the air; when a worker slightly presses down, a magnetic induction switch and an induction magnet get close and a signal is output to a transmission element; the signal is transmitted to a special controller to judge: 1, if the two bolts are inserted in place, an explosion-proof solenoid valve is switched on; and 2, if any one of the two bolts is not inserted in place, the signal is output to control the explosion-proof solenoid valve to be switched off, so that a gas path in a low-speed clutch gas path pipeline is blocked and a single suspension ring accident is prevented from occurring. After suspension rings move downward to a platform, the worker can pull out the safety bolts in a slightly forceful manner; and when the adsorption force of the safety bolts drives an annular magnet sleeve part to move downward, the safety bolts are pulled out. A waterproof protective sleeve and an outer wall of an electronic element mounting hole are in thread connection, and a pin rod with a limiting lug boss and the electronic element mounting hole are in the thread connection.
