Degree sensor will represent that rig is in the negative signal of rollback state to processor output.Brill so can be sensed by magnetic induction
The strong and weak change of bar internal magnetic flux, advances in conjunction with the unit head detected by acceleration transducer or fallback state judges to work as
The working condition of preceding rig is counted with to rig reciprocal time.And when there is kelly, now, unit head will be with acceleration
Degree sensor continues to move back and forth, and acceleration transducer will drilling rod be motionless to output signal of processor, but during because of kelly, now
The magnetic flux in drilling rod detected by linear hall sensor is constant, and now, linear hall sensor is not exported to processor
Signal, it is invalid that back and forth can be considered as this unit head by the processor for recording unit head reciprocal time, not records.Thus
It is possible to prevente effectively from the problem still counted during kelly, and then the certainty of measurement of measuring instrument can be improved.
Measuring instrument is installed, measuring instrument can be counted to the reciprocating motion number of times of unit head on rig provided by the present invention
Number, and can avoid being still carried out during kelly the problem of counting, its simple structure, certainty of measurement is high.
Brief description of the drawings
Fig. 1 is that rig provided by the present invention is drilled a kind of structure principle chart of embodiment of depth calibrator；
Fig. 2 is the fundamental diagram of measuring instrument shown in Fig. 1；
Fig. 3 is that measuring instrument measurement is drilled the FB(flow block) of depth.
Specific embodiment
A kind of embodiment of depth calibrator as shown in figure 1, rig is drilled, the measuring instrument in the embodiment includes being used for
The unit head 2 of rig move back and forth both sides before and after the unit head 2 that is placed on direction for magnetizing the drilling rod driven by unit head 2
4 permanent magnet excitation device 1 and for it is corresponding with the drilling rod 4 after magnetization with measure drilling rod internal magnetic flux change magnetic strength inductive sensing
Device, magnetic induction sensor herein is the linear hall sensor 5 for arranging drilling rod periphery after magnetization.Measuring instrument is also wrapped
Include for being installed on the unit head 2 of rig the acceleration transducer 3 to measure unit head advance or the mobile status for retreating, survey
Amount instrument also includes being used for what is be connected with the signal output part of linear hall sensor 5 and the signal output part of acceleration transducer 3
For the processor counted to unit head reciprocation period, the signal output part of processor is connected with display circuit.
Fig. 2 show the fundamental diagram of measuring instrument, when unit head 2 is with the fast approaching linear hall sensor 5 of drilling rod 4
When, the magnetic flux that linear hall sensor 5 is detected in the drilling rod after magnetization changes from weak to strong.And work as unit head and quickly leave linearly
During Hall sensor, linear hall sensor detects magnetic flux inside drilling rod by dying down by force.
In the present embodiment, permanent magnet excitation device and magnetic induction sensor are placed in unit head both sides, in other embodiments,
Permanent magnet excitation device can also be arranged in the front side of unit head.
In the present embodiment, for detect the drilling rod internal magnetic flux after magnetization change magnetic induction sensor for it is linear suddenly
That sensor, in other embodiments, magnetic induction sensor can also be multigroup detection coil, and the drilling rod being magnetized is by phase
When answering coil, the meeting of change causes coil to produce electric current, and the electric current in detection coil can be detected.
The present invention also provides a kind of embodiment of rig, the structure of the rig in the embodiment and rig of the prior art
Structure it is roughly the same, its difference is essentially consisted in be provided with rig and drilled the measuring instrument of depth, rig bag for measuring rig
Fuselage is included, the unit head 2 being equipped with for driving drilling rod to rotate punching is moved back and forth on fuselage, the measuring instrument is using such as Fig. 1
Shown structure, be will not be repeated here, and the permanent magnet excitation device 1 and linear hall sensor 5 of measuring instrument are placed in unit head 2
Front and rear both sides, meanwhile, acceleration transducer 3 is installed on unit head 2 and is together moved back and forth with unit head 2.
In the present embodiment, permanent magnet excitation device and linear hall sensor are placed in the front and rear both sides of unit head, at other
In embodiment, it is also possible to which permanent magnet excitation device and linear hall sensor are placed in the front side of unit head.
When unit head 2 creeps into, the connection acceleration transducer 3 of unit head 2 promotes drilling rod 4 to move forward, and drilling rod 4 is by permanent magnetism
Excitation unit 5 magnetizes because drilling rod have it is hysteresis, when 4 fast approaching linear hall sensor 5 of drilling rod, linear Hall pass
Sensor 5 can detect drilling rod internal magnetic flux and change from weak to strong, and detected signal is conveyed to place by linear hall sensor 5
Reason device, meanwhile, acceleration transducer will represent that rig is in the positive signal of drilling state to processor output.
When unit head 2 retracts, unit head 2 is retreated together with acceleration transducer 3, detected by linear hall sensor 5
Drilling rod in magnetic flux will be by dying down by force, detected signal is conveyed to processor by linear hall sensor 4, meanwhile,
Acceleration transducer will represent that rig is in the negative signal of rollback state to processor output.
And when there is kelly, now, unit head 2 will be moved back and forth with acceleration transducer 3, acceleration transducer 3
Will be to output signal of processor.Drilling rod is motionless during kelly, now the magnetic flux in the drilling rod detected by linear hall sensor 5
Constant, now, not to output signal of processor, the processor for recording unit head reciprocal time can for linear hall sensor 5
It is invalid that this unit head is back and forth considered as, and not records.
When depth is drilled in specifically used measuring instrument measurement, the idiographic flow when process measurement is squeezed into is as shown in Figure 3.Survey
During amount, unit head is completed into a drilling working condition and a backoff operation state as an oscillation cycle, counted once,
When linear hall sensor is not to output signal of processor, will unit head be back and forth considered as invalid and ignore.Assuming that dynamic
The drilling stroke l of power head, the drilling number of times of unit head is n, then it is then L=l*n that rig drills depth.
