In view of in the prior art, prevent that putting off device can not be matched well with advanced Drilling Control system, this reality
With new by control system of preventer and electronics automatic well drill Winch control system (especially Amphion well systems) organic knot
Merging is transformed, so propose it is new it is anti-put off safety mutually-locking device, i.e., driller house inner blowout preventer beep box and drilling well
Winch parking brake is associated, and that realizes that winch when any preventer is closed can not all operate safe and reliable anti-puts off function.
Fig. 1 is the anti-electrical schematic diagram for putting off safety interlock system of the present utility model, it is shown that preventer is prevented with winch
The interlocked control put off.There are 5 closing indicator lamps on the right side of Fig. 1, correspond to 5 preventers respectively, it is right when each preventer is closed
The closing indicator lamp answered will light.Indicator lamp is closed for this 5 to be parallel to respectively on the coil of 5 relays (KA1~KA5),
13,14 terminals on relay are exactly winding wiring terminal, and 5 relays take a normally opened contact (KA1 '~KA5 ') simultaneously respectively
It is linked togather.It is the more control switch that transfinites to switch CB (breaker), and when this switch CB closures, this prevents putting off safety interlock system work
Make；When being not desired to the system, or need when using winch by force in the case that preventer is closed, will can transfinite more control switch
CB disconnects, and now whole circuit is obstructed, and system does not work.
Now, if when some or several closings of this 5 preventers, corresponding closing lantern festival obtains electric light, then
Corresponding relay also mutually deserved electricity, then corresponding normally opened contact also close, so as to which circuit is connected, relay KA6 and time
Relay KT1 obtains electric.KA6 obtains electric, then KA6 normally opened contact KA6 ' will be closed, and normally opened contact KA6 ' is stayed with winch
Car ON knobs (terminal 23-24) are in parallel, are equivalent to knob action, send parking instruction to winch, and then winch will stay
Car brakes.
Because knob is all automatically reset, it will not be always held at ON position, and can return to middle position.So KA6 '
Contact can not allow it to be always maintained at closure, it is necessary to allow it to return to open position, and we have just added time relay KT1 to come here
Realize this function.Time relay KT1 function is Time-delayed trigger, when KT1 is obtained it is electric when will not act immediately, have delay
Time, the time, we were arranged to 1.5 seconds (simulation driller manual operation) here.We by a KT1 normally-closed contact KT1 ' with
Relay KA6 coils are connected, when KT1 obtain it is electric spent 1.5 seconds after, normally-closed contact KT1 ' disconnects, and at this moment relay KA6 coils are just
Dead electricity, just it is disconnected so as to KA6 normally opened contact KA6 ', is also achieved that the function that knob resets.
In addition, when winch parking brake, winch parking knob is got into OFF can open brake.But anti-
When spray apparatus is closed, system of the present utility model, which must assure that, does not allow it to open brake.Here, used that time relay KT1's is another
One normally-closed contact KT1 ", is connected on winch parking OFF knobs (terminal 13-14), and KT1 obtains the normally-closed contact after electric 1.5 seconds
KT1 ' disconnects, and then normally-closed contact KT1 " disconnects, and parking OFF switch loop disconnects, and now operates selection knob again to OFF
Also useless, winch parking brake can not perform releasing.And when all preventers are opened, close lantern festival and extinguish, from
And relay KA1~KA5 coil losing electricities, normally opened contact KA1 '~KA5 ' disconnect, circuit just disconnects, and time relay KT1 just loses
Electricity, the normally-closed contact KT1 " for being connected in series to winch parking OFF knobs recover closure, and parking OFF switch loop is connected, and at this moment operation twists
Car parking knob is opened to OFF can and braked.
It should be noted that when more control of transfiniting switchs CB and disconnected, the KT1 " normally-closed contacts connected with Parking Off close
Close, now parking brake solution division operation winch can be realized and make a trip and protect by force well head when preventer is closed by driller
Function.Because relay KA6 normally opened contact KA6 ' and parking ON switch is parallel relationship, the normally closed of time relay KT1 is touched
Point KT1 " and parking OFF switch are series relationships, so work as whole circuit dead electricity, when safety interlock system fails, Bu Huiying
Ring other functions before not installing the system.
Prevent putting off safety interlock system embodiment principle similarly with above-mentioned, the utility model also provides a kind of drilling well and set
It is standby, it include it is foregoing it is anti-put off safety interlock system, and well drilling hoist and preventer, wherein, it is described anti-to put off safety mutual
Lock system is integrated in well drilling hoist parking brake console and preventer beep box.Due to the technical characteristic in previous embodiment
This drilling equipment embodiment is can apply to, thus it is no longer repeated.
In summary, it is of the present utility model to prevent putting off safety interlock system and the drilling equipment comprising the system, from blowout prevention
The closing indicator lamp number of winning the confidence on device driller's console, it is in parallel with parking brake Parking On loops all the way, all the way with
Parking Off circuit in series；After any preventer is closed in place, close indicator lamp and light, now, be connected in parallel on the indicator lamp
On the actuating of relay, corresponding with relay normally opened contact closure is anti-to put off control circuit connection, the time relay, in
Between relay work；Energization delay relay timing 1.5 seconds, the normally opened contact of the auxiliary reclay in parallel with Parking On closes
Opened again after closing 1.5 seconds, so as to activate winch parking brake；With the normally-closed contact of the Parking Off time relays connected
Open, now will be unable to carry out brake reset Parking Off operations, i.e., when any preventer is closed, stopped equivalent to parking
Car starts, and can not release parking brake before preventer opening, winch can not operate.When all preventers are in open position, close
The relay electric-loss closed on indicator lamp, prevent that putting off control circuit restPoses, now driller can carry out Parking Off
Operation, winch parking brake is released, can be with normal operating winch.The utility model effectively overcomes of the prior art a variety of scarce
