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.

Detailed description of the invention
It is an object of the invention to so to complete:
Safety pin is somewhat firmly inserted elevator in ear by two hand-held safety pin personnel, safety pin is sent to nonshared control unit by what sense already inserted into the signal that puts in place, nonshared control unit judges: 1, if two latches are all inserted into position, export signal control explosion-proof solenoid valve and open, make gas circuit in low-speed clutch gas circuit pipeline unimpeded, 2, if any one is not inserted into position in two latches, then output signal controls explosion-proof solenoid valve disconnection, make gas circuit in low-speed clutch gas circuit pipeline obstructed, driller personnel now trip-out action will not work, stop the generation of single-ring accident.Powerful permanent magnet it is inlaid with bottom safety pin, when safety pin inserts elevator in ear, due to strong magnets effect, safety pin is attracted on elevator, even if elevator overturns, safety pin comes off in elevator without because of gravity and centrifugal force, and then prevents elevator from coming off from suspension ring, cause that elevator is pounded to rig floor from falling in the air, injure personnel or equipment etc..
Three, the present invention focus on safety pin, be made up of following 14 parts: (1) waterproof nut: after being used for tightening, prevent muddy water from entering in element installing hole and battery hole.(2) safe becket bridle: for wire rope handling, hangs latch on suspension ring, it is prevented that come off.(3) battery settling hole: install aneroid battery and power to electronic component.(4) electronic component installing hole: interior installation sensing and radiated element.(5) magnet proximity switch: be used for sensing whether latch is inserted into position.(6) water-proof jacket: be used for preventing muddy water from entering, causes annular magnet external member normally to move up and down and correctly whether sensing latch is inserted into position.(7) spacing ripple pearl: be used for preventing owing to shake or elevator upset cause mistake induced signal.(8) annular magnet external member: be used for installing 2 blocks of annular magnets.(9) sensing annular magnet: make magnet proximity switch Guan Bi or conducting owing to it moves up and down.(10) absorption annular magnet: for safety pin is adsorbed in elevator.(11) with positive stop lug boss pin rod: limit convex is for limiting the displacement of annular magnet external member, and restriction annular magnet external member comes off from pin rod simultaneously, pin rod is used for inserting upper and lower two the pin in ear of elevator.(12) nonshared control unit: judge latch signal and control explosion-proof solenoid valve opening and closing.(13) low-speed clutch pipeline: existing equipment.(14) explosion-proof solenoid valve: be installed on low-speed clutch pipeline, control gas is unobstructed or closes.
Four, safety pin operation principle (referring to Fig. 3):
When safety pin inserts in ear, absorption annular magnet (10) strong adsorption is on elevator, staff somewhat exerts oneself, annular magnet external member (8) moves up, make induced magnet (9) and magnetic induction switch (5) close, now magnetic induction switch (5) senses that latch is already inserted into signal, and output signal to the radiated element in element installing hole (4), radiated element in element installing hole (4) transmits signals to nonshared control unit (12), nonshared control unit (12) judges: 1, if two latches are all inserted into position, export signal control explosion-proof solenoid valve (14) and open, make low-speed clutch gas circuit pipeline (13) interior gas circuit unimpeded, 2, if any one is not inserted into position in two latches, then output signal controls explosion-proof solenoid valve (14) disconnection, make low-speed clutch gas circuit pipeline (13) interior gas circuit obstructed, driller personnel now trip-out action will not work, stop the generation of single-ring accident.Owing to location ripple pearl (7) makes not produce displacement between annular magnet external member (8) and magnetic induction switch (5), it is prevented that produce rub-out signal and malfunction due to shake or elevator upset.After trip-out completes, after suspension ring move down into platform, safety pin is somewhat firmly extracted by staff, now owing to absorption annular magnet (10) strong adsorption power makes annular magnet external member (8) move down, make induced magnet (9) away from magnetic induction switch (5), now magnetic induction switch (5) senses that signal extracted by latch, and output signal to the radiated element in element installing hole (4), radiated element in element installing hole (4) transmits signals to nonshared control unit (12), nonshared control unit (12) judges that two safety pins are extracted, next samsara can be entered.Water-proof jacket (6) adopts with the outer wall of electronic component installing hole (4) threadeds, and plays good sealing function and prevents muddy water from entering annular magnet external member inwall (8), it is to avoid cannot move and rub-out signal.With threadeding between band positive stop lug boss pin rod (11) with electronic component installing hole (4), it is simple to dismounting and maintenance.
