The present invention also proposes a kind of rotary drilling rig of the elevator pressurized control device comprised in previous embodiment.The following describes the control process of elevator pressurized control device when rotary drilling rig works.
When rotary drilling rig carries out elevator pressurization construction, first pressurization select switch 6 is opened, 126 pin senses of controller 9 are to incoming signal, control 105, 106 pins export control signal, pressurization is made to promote electromagnetic valve 101, pressurization is transferred electromagnetic valve 102 and is obtained electric, now operated pilot handle, open guide's oil circuit, guide oil opens working connection, make pressurization elevator pressure switch 7 close simultaneously, 123 pin senses of this Time Controller are to incoming signal, control 117 pins and export control signal, pressurization elevator braking electromagnetic valve 11 is obtained electric closed, to open pressurization hoist brake, hydraulic control system can carry out hoisting, lowering operation.When stopping pilot handle operation, guide oil distress resolves, working connection is closed, elevator pressure switch 7 of simultaneously pressurizeing disconnects, and 123 pin senses of this Time Controller, can after a period of time T that time delay is default less than incoming signal, control 117 pins to stop exporting control signal, make pressurization elevator braking electromagnetic valve 11 dead electricity, to close pressurization hoist brake, hydraulic efficiency pressure system can be made to stop hoisting, lowering operation.Time-delay closing pressurization hoist brake can reduce the impact of braking to hydraulic efficiency pressure system, extends the service life of hydraulic part, and the rig that minimizing braking causes rocks.
When elevator pressurization occurs abnormal, the master file hoisting force that sensor detects can increase at once, when the master file hoisting force that sensor detects exceedes default hoisting force threshold value, 152 ends of this Time Controller 9 detect incoming signal, and control the first output interface 106 end or 105 end no-outputs, pressurization is made to transfer electromagnetic valve 102 or pressurization lifting electromagnetic valve 101 dead electricity, disconnect guide's oil circuit, pressurization elevator pressure switch 7 disconnects simultaneously, 123 ends of controller 9 can't detect incoming signal, then control the second output interface 117 end no-output, make pressurization elevator braking electromagnetic valve 11 dead electricity, to close pressurization hoist brake.Though now pilot handle stops pressurized operation not yet, compression motion stops automatically, cannot continue pressurization.Now can shut down, after trouble-shooting, then enabling.Thus when elevator pressurization occurs abnormal, pressurization elevator can be made to stop pressurization, the structural failure of rig can be avoided, improve the safety and reliability of elevator pressurization type construction.To make, pressurization promotes electromagnetic valve 101 to the output interface no-output of the present embodiment middle controller, electromagnetic valve 102 is transferred in pressurization, pressurization elevator braking electromagnetic valve 11 dead electricity, be only the exemplary mode of one of electromagnetic valve dead electricity, other control signals can also be exported to make electromagnetic valve dead electricity.
Drill bit transfer in hole or dug soil upwards promote time, master file hoisting force exceedes default hoisting force threshold value, then the situation that the pressurization of above-mentioned elevator is abnormal can occur.Such as, drill bit is transferred in hole, and when drill bit not yet arrives at the bottom of hole, unit head pressurization key and drilling rod shift to an earlier date locking, and operator does not realize, when still carrying out pressurized operation, then elevator pressurization may occur abnormal.

Further, when the second input interface of controller 9 can't detect the incoming signal of pressurization elevator pressure switch 7, after a period of time that controller 9 time delay is preset, send control signal to pressurization elevator braking electromagnetic valve 11 and make its dead electricity, to close pressurization hoist brake.Time-delay closing pressurization hoist brake can reduce the impact of braking to hydraulic efficiency pressure system, extends the service life of hydraulic part, and the rig that minimizing braking causes rocks.
Further, master file hoisting force can also be transferred to telltale 3 and show by controller 9, makes operator can observe the change of numerical value at any time, if numerical value change is abnormal, can shut-down operation immediately, more intuitively, conveniently, safety.
Further, when carrying out elevator pressurization construction, when the 3rd input interface of controller 9 detect that pressurization select switch 6 sends carry out the indicator signal of elevator pressurization, controller 9 sends control signal to pressurized control electromagnetic valve 10, and to make it obtain electric; When the second input interface of controller 9 detects the incoming signal of pressurization elevator pressure switch 7, controller 9 sends control signal to pressurization elevator braking electromagnetic valve 11, and to make it obtain electric, to open pressurization hoist brake, hydraulic control system hoisting, lowering operation can be carried out.
One of ordinary skill in the art will appreciate that all or part of step realizing above-described embodiment can have been come by hardware, the hardware that also can carry out instruction relevant by program completes, described program can be stored in a kind of computer-readable recording medium, the above-mentioned storage medium mentioned can be read-only memory (ROM), disk or CD etc.
Embodiment described above is only in order to illustrate technical scheme of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, and any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
