Range measurement, precision are high, anti-light, electrical interference ability is strong.The laser sensor is connected with PLC control system, the PLC controls
System processed is connected by drive module with motor control so that PLC passes through coupled drive after optical signal is received
Dynamic model block controls the movement of motor, reaches following effect：When oil well works normally, feed rod does not come off, and Laser emission goes out
After going, stopped by feed rod, another sensor does not receive laser light signal, will not trigger motor action；Once feed rod breaks
Split and come off, laser signal smoothly reaches the sensor on opposite, sends an electric signal to motor, realizes closing well.
Further, two of the double ram type preventer full envelope gate end symmetricals are cased with two interior hex sockets,
And be connected by second shaft coupling with the driven shaft of the deceleration device, the driving shaft of the deceleration device passes through first shaft coupling
It is connected with motor transmission, to acquire power.
Further, the motor is DC brushless motor, and because the installation dimension of stepping and servomotor is excessive, price is inclined
Height, no retarder can bear so big moment of torsion, thus select reasonable price, it is compact-sized and with retarder coordinate make
With moment of torsion can reach the DC brushless motor of expected requirement.Due to mainly driving leading screw rotation in the live motor that recovers the oil, therefore
Without considering its kinematic accuracy.When there is emergency case, it is necessary to which motor has larger starting torque, start action and last in flashboard
When reaching center, frictional resistance is maximum, and when polished rod comes off, motor must occur to make in 10 seconds in blowout
Flashboard reaches center, realizes that closing well acts.
Further, baffle is fixed with the babinet of the reducing gear, to cover reducing gear and double disc blowout prevention
Rotating part between device, prevent by seal gate axis entirely rotation caused by security incident, support personnel safety.
The utility model has the advantage of：Not only reduce the input of human cost, ensure the person peace of construction personnel
Entirely, and after the crisis situations such as overflow, well kick, blowout are detected, which can respond rapidly to close oil well so that production
Process is more safe and reliable.
The utility model is described in further detail with reference to the accompanying drawings and examples.

Embodiment
The preferred embodiment of the utility model is illustrated below, it will be appreciated that preferred embodiment described herein
It is only used for describing and explaining the present invention, is not used to limit the utility model.
Embodiment 1
As shown in Figs. 1-2, a kind of oil well numerical control blowout hookup, including double ram type preventer 2, the double ram type preventer 2
Both ends be connected by the transmission of reducing gear 8 and motor 12；The upper end neck of the double ram type preventer 2 is symmetrically installed with two
Laser sensor 1, a transmitting laser, another receives laser；The laser sensor 1 is connected with PLC control system, described
PLC control system is connected by drive module with motor control so that PLC is after optical signal is received by coupled
Drive module control motor movement, so as to reach following effect：When oil well works normally, feed rod does not come off, and swashs
After light emitting is gone out, stopped by feed rod, another sensor does not receive laser light signal, will not trigger motor action.One
