Rig provided by the utility model is provided with measuring instrument, and measuring instrument can count the reciprocating motion number of times of unit head, and still carries out the problem that counts when can avoid kelly, and its structure is simple, and certainty of measurement is high.
Accompanying drawing explanation
Fig. 1 is that rig provided by the utility model is drilled the structure principle chart of a kind 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 the degree of depth.
Detailed description of the invention
As shown in Figure 1, a kind of rig is drilled the embodiment of depth calibrator, measuring instrument in this embodiment comprise for move back and forth at the unit head 2 of rig both sides before and after unit head 2 that direction is placed in for magnetize the drilling rod 4 driven by unit head 2 permanent magnet excitation device 1 and for corresponding to measure the magnetic induction sensor that drilling rod internal magnetic flux changes with the drilling rod 4 after magnetization, magnetic induction sensor is herein the linear hall sensor 5 for arranging drilling rod periphery after magnetization.Measuring instrument also comprises on the unit head 2 for being installed in rig to measure the acceleration transducer 3 of the mobile status of unit head advance or retrogressing, measuring instrument also comprises the processor for counting unit head reciprocation period that the signal output part for the signal output part and acceleration transducer 3 with linear hall sensor 5 is connected, and the signal output part of processor is connected with display circuit.
Figure 2 shows that the fundamental diagram of measuring instrument, when unit head 2 is with drilling rod 4 fast approaching linear hall sensor 5, the magnetic flux in the drilling rod after linear hall sensor 5 detects magnetization changes from weak to strong.And when unit head leaves linear hall sensor fast, linear hall sensor detects that the magnetic flux of drilling rod inside is by dying down by force.
In the present embodiment, permanent magnet excitation device and magnetic induction sensor are placed in unit head both sides, and in other embodiments, permanent magnet excitation device also can be arranged in the front side of unit head.
In the present embodiment, magnetic induction sensor for the change of the drilling rod internal magnetic flux after detection of magnetized is linear hall sensor, in other embodiments, magnetic induction sensor can also for organize magnetic test coil more, the drilling rod be magnetized is when by corresponding coil, the meeting of change causes coil generation current, can detect the electric current on magnetic test coil.
The utility model also provides a kind of embodiment of rig, the structure of the rig in this embodiment is roughly the same with the structure of rig of the prior art, its difference is mainly to be provided with on rig to drill the measuring instrument of the degree of depth for measuring rig, rig comprises fuselage, fuselage moves back and forth the unit head 2 be equipped with for driving drilling rod to rotate punching, described measuring instrument adopts structure as shown in Figure 1, do not repeat them here, be placed in the permanent magnet excitation device 1 of measuring instrument and linear hall sensor 5 both sides, front and back of unit head 2, simultaneously, degree of will speed up sensor 3 to be installed on unit head 2 and together to move back and forth with unit head 2.
In the present embodiment, permanent magnet excitation device and linear hall sensor are placed in the both sides, front and back of unit head, in other embodiments, also permanent magnet excitation device and linear hall sensor all can be positioned over the front side of unit head.
When unit head 2 creeps into, unit head 2 is communicated with acceleration transducer 3 to be promoted drilling rod 4 and moves forward, drilling rod 4 is magnetized by permanent magnet excitation device 5, because drilling rod has hysteresis, when drilling rod 4 fast approaching linear hall sensor 5, linear hall sensor 5 can detect that drilling rod internal magnetic flux changes from weak to strong, and detected signal is flowed to processor by linear hall sensor 5, meanwhile, by exporting to processor, acceleration transducer represents that rig is in the positive signal of the state of creeping into.
When unit head 2 rollback, unit head 2 retreats together with acceleration transducer 3, magnetic flux in drilling rod detected by linear hall sensor 5 will by dying down by force, detected signal is flowed to processor by linear hall sensor 4, meanwhile, by exporting to processor, acceleration transducer represents that rig is in the negative signal of rollback state.
And when there is kelly, now, unit head 2 will move back and forth with acceleration transducer 3, acceleration transducer 3 will to output signal of processor.During kelly, drilling rod is motionless, magnetic flux in drilling rod now detected by linear hall sensor 5 is constant, and now, linear hall sensor 5 is not to output signal of processor, it is invalid that this unit head can back and forth be considered as by the processor for recording unit head reciprocal time, refuses record.
When the degree of depth is drilled in the measurement of concrete use measuring instrument, the idiographic flow when squeezing into process measurement as shown in Figure 3.During measurement, unit head is completed one and creep into duty and a backoff operation state as an oscillation cycle, counting once, when linear hall sensor is not to output signal of processor, is back and forth considered as invalid by unit head and ignores.That supposes unit head creeps into stroke l, and the number of times that creeps into of unit head is n, and so rig drills the degree of depth then for L=l*n.
