Specific embodiment:
The preferred embodiments of the present invention will be described in detail with reference to the accompanying drawing, so that advantages and features of the invention energy
It is easier to be understood by those skilled in the art, so as to make a clearer definition of the protection scope of the present invention.
A kind of rotary drilling rig as shown in Figure 1 creeps into self-locking device, including self-locking pilot valve 1, the self-locking electromagnetism of annular automatically
Iron 2, platen 3 and handle 4, the platen 3 are fixed on 4 bottom end of handle, and the self-locking pilot valve 1 is correspondingly arranged at 3 side of platen
Lower section, the self-locking electromagnet 2 of annular is set in self-locking 1 top of pilot valve, annular self-locking electricity when handle 4 pushes maximum position
Magnet 2 can be attracted with platen 3 and lock.
Self-locking 1 left position of pilot valve control power head drilling, the plug of self-locking 1 left position of pilot valve is blocked up and is changed to the self-locking electromagnetism of annular
3 structure of platen is changed to permit magnetic adsorbable structure by iron 2.When the self-locking electromagnet 2 of annular obtains electric, self-locking 2 shape of electromagnet of annular
At magnetic field, control crank 4 to left position, that is, power head creeps into position at this time, and platen 3 is pressed onto the self-locking electromagnet 2 of annular and keeps that lock is sucked
Determine state, while platen 3 pushes the spool of self-locking pilot valve 1, realizes drilling lock function.
A kind of automatic drilling control system with above-mentioned automatic drilling self-locking device as shown in Figure 2, including power head
Motor 11, main valve 12, self-locking pilot valve 13, pressurization solenoid valve 4, main pump 5, attached pump 6, auxiliary valve 7, floating solenoid valve 8, hoist motor
9 and pressurization oil cylinder 10, the main valve 12 be arranged between main pump 5 and power head motor 11, the pressurization oil cylinder 10 passes sequentially through
Auxiliary valve 7, pressurization solenoid valve 4 are connect with self-locking pilot valve 13, and attached pump 6, the self-locking elder generation are arranged between the auxiliary valve 7 and main pump 5

The drilling locking press button is that automatic creep into enables button, the button for using handle to carry.
Whether the pressure sensor detection system pressure judges control logic by system pressure as mistake proofing condition
It executes, avoids maloperation.When even pressure sensor normally passes pressure signal back, the executable automatic drilling of controller judgement, if
When sensor no pressure signal or pressure signal exception, controller judgement does not execute automatic drilling logic.
The depth sensor real-time monitoring creeps into state, and when single drilling depth reaches default value, system is sentenced
It is disconnected to complete current drilling work, stop executing automatic drilling logic immediately.
It is as follows that rotary drilling rig of the invention creeps into control method logic automatically:
Control logic one: rotary drilling rig starting operating, pressure sensor pass pressure signal, operation handle 4 back to controller
Drilling movement is executed to left position, is pressed locking press button (crawl), signal passes controller, controller output signal to self-locking relay back
Device, self-locking electromagnet annular at this time obtain electric, and magnetic force is sucked platen 3, and state is crept into 4 left position of lock handle, and control guide oil is connected
To the b1 mouth of main valve 12, push the spool of main valve 12 that the B mouth of power head motor 11 is made to be kept as oily drilling state.
Control logic two: pressing locking press button (crawl), and after interval time t1 second, controller exports pressurization signal to pressurization
Relay, the solenoid valve 4 that pressurizes obtain electric, the P ' mouth for the solenoid valve 4 that pressurizes at this time and the connection of self-locking 13 left position guide oil of pilot valve, promotion
Auxiliary 7 spool of valve obtains pressurization oil cylinder 10 oily, i.e. execution compression motion.Controller disconnects pressurization signal after interval time t2 second, adds
4 power loss of pressure electromagnetic valve resets, and compression motion stops；Pressure-operated again after interval time t1 second executes time t2 seconds；So follow
Ring realizes that rotary drilling rig Self-pressurizing agri creeps into function, until single drilling depth reaches default value or presses again self-locking
Button (crawl).
Control logic three: pressing locking press button (crawl), and after interval time t1 second, controller exports floating sign to floating
Relay, control floating solenoid valve 8 obtain electric, A, B mouth connection realization floating movement of hoist motor 9 at this time, interval time t2 second
Controller disconnects floating sign afterwards, and floating movement stops.Floating movement is executed after interval time t1 second again, executes time t2
Second；So circulation realizes that rotary drilling rig Self-pressurizing agri creeps into function, until single drilling depth reaches default value or again
It is secondary to press locking press button (crawl).
When single drilling depth reaches default value or presses locking press button (crawl) again, system judgement is completed
Current drilling work, stops executing the above logic immediately.
The embodiments described above only express several embodiments of the present invention, and the description thereof is more specific and detailed, but simultaneously
It cannot therefore be construed as limiting the scope of the patent.It should be pointed out that coming for those of ordinary skill in the art
It says, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to protection of the invention
Range.
