The drilling process is to provide torque for the drill rod through the power head and transmit pressurizing force to the drill bit of the drill rod, so that the drill bit rotates to break rock and soil; the telescopic process of the drill rod is that in the process of drilling construction, when the current length of the drill rod is not long enough or is too long, the rotary drilling rig can lift the drill rod up and down through the power head, and the telescopic operation of the drill rod is realized.
In some possible embodiments, the obtaining of the first relative displacement of the power head and the mast may be achieved by a displacement sensor, where the type of displacement sensor may be an infrared sensor, a laser sensor, etc., and the present application is not limited thereto.
It will be appreciated that the first relative displacement described above may be: in the process of drilling construction by the rotary drilling rig, the relative distance between the current position of the power head and the initial position of the power head when the drilling construction begins.
S110, acquiring second relative displacement of the power head and the mast in the process of stretching and retracting the drill rod of the rotary drilling rig.
Correspondingly, the second relative displacement of the power head and the mast can be obtained through a displacement sensor, wherein the type of the displacement sensor can also be an infrared sensor, a laser sensor and the like, and the application is not limited to the type of the displacement sensor.
It will be appreciated that the second relative displacement described above may be: in the process of stretching and retracting the drill rod of the rotary drilling rig, the relative distance between the positions of the power heads at the moment when the drill rod stretches and stops.
It will be appreciated that in performing S100 and S110 described above, the acquired first and second relative displacements are at the same time.
S120, determining the bit depth of the drill rod according to the first relative displacement and the second relative displacement.
In some possible embodiments, since the acquired first relative displacement and the second relative displacement are at the same time, compensating the second relative displacement into the first relative displacement can obtain the accurate bit depth of the drill rod at the current time.
It will be appreciated that since the process of obtaining the first relative displacement of the power head and the mast and the second relative displacement of the power head and the mast is simple and accurate, the depth of the drill bit of the drill pipe can be simply and accurately determined from the first relative displacement and the second relative displacement. Therefore, the embodiment of the application can simply and accurately measure the drilling depth of the drill bit.
Further, as to how to obtain the first relative displacement between the power head and the mast during the drilling process of the rotary drilling rig, referring to fig. 3, S100 may include:
and S100A, when the drill rod is placed on the working surface, acquiring a first position of the power head on the mast.
As shown in fig. 4, the rotary drilling rig 100 at least includes a power head 120, a mast 130, and a drill rod 110, and the drill rod 110 includes a drill bit 111. And in fig. 4, the drill rod 110 of the rotary drilling rig 100 is just placed on the work surface, at which point the controller 140 of the rotary drilling rig can obtain a first position a of the power head 120 on the mast.
S100B, acquiring a second position of the power head on the mast in the drilling construction process of the rotary drilling rig.
Taking the drilling work process of fig. 4 through 5 as an example, the controller 140 of the rotary drilling rig may obtain the second position B of the power head 120 on the mast.
And S100C, determining the first relative displacement of the power head and the mast according to the first position and the second position.
Continuing taking the drilling construction process from fig. 4 to fig. 5 as an example, determining the first relative displacement of the power head and the mast according to the first position and the second position to obtain the AB. Obviously, the depth of the drill bit is AB at this time.
Further, for convenience of operation by the operator. In some possible embodiments, S100A may include, when the drill pipe is placed on the work surface, how to "acquire the first position of the power head on the mast: and responding to a first operation instruction of an operator, and acquiring a first position of the power head on the mast.
For example, a calibration button may be provided on the console of the rotary drilling rig 100 that the operator may press to send a first operating command to the controller 140 when he is operating the rotary drilling rig 100 to place the drill pipe 110 on the work surface in preparation for a drilling operation. At this point, the controller 140 of the rotary drilling rig may obtain a first position of the power head 120 on the mast 130 in response to a first operating command of an operator.
It is also added that, in order to avoid misoperation of the operator, the controller 140 does not respond to the signal of the calibration button within a preset time period after the operator can press the calibration button.
Further, when the current length of the drill rod is not long enough or too long, and the drill rod needs to be lengthened or shortened, with respect to how to "obtain the second relative displacement between the power head and the mast during the expansion and contraction process of the drill rod of the rotary drilling rig", referring to fig. 6, S110 may include:
S110A, at the beginning time of the rotary drilling rig to stretch and retract the drill rod, acquiring a third position of the power head on the mast.
Taking the process of extending the drill pipe 110 from fig. 5 to fig. 7 as an example, at the beginning of the expansion and contraction of the drill pipe 110 by the rotary drilling rig 100, the controller 140 of the rotary drilling rig may obtain the third position B of the power head 120 on the mast 130.
S110B, at the end time of the rotary drilling rig to stretch and retract the drill rod, acquiring a fourth position of the power head on the mast.
Continuing with the example of the process of extending the drill pipe 110 from fig. 5 to fig. 7, at the end of the extension and retraction of the drill pipe 110 by the rotary drilling rig 100, the controller 140 of the rotary drilling rig may obtain the fourth position C of the power head 120 on the mast 130.
And S110C, determining the second relative displacement of the power head and the mast according to the third position and the fourth position.
Continuing with the example of the process of extending the drill pipe 110 from fig. 5 to fig. 7, a second relative displacement of the power head and the mast is determined as BC based on the third position and the fourth position.
It will be appreciated that since the first and second relative displacements are obtained at the same time, the first relative displacement of the power head and mast is AC at the time of fig. 7. At this time, the second relative displacement BC is compensated to the first relative displacement AC, so as to obtain the bit depth AB at the current moment.
The compensation process can be as follows: firstly, assuming that the first relative displacement is positive downwards along the drill rod and negative upwards along the drill rod; the second relative displacement is positive up the drill rod and negative down the drill rod, then during the extension of the drill rod 110 of fig. 5 to 7, the first relative displacement is +ac, the second relative displacement is +cb, and the bit depth at the current time is ac+cb=ab.
It should be noted that, in the process of shortening the drill rod, the manner of obtaining the second relative displacement between the power head and the mast corresponds to the above process, and will not be described herein again.
Further, for convenience of operation by the operator. In some possible embodiments, S110A may include, at a start time of the drill rod extension of the rotary drilling rig, for how to "acquire the third position of the power head on the mast": and responding to a second operation instruction of an operator, and acquiring a third position of the power head on the mast. The step of obtaining the first position of the power head on the mast may refer to the step of responding to the first operation instruction of the operator, which is not described herein.
Accordingly, at the end of the extension and retraction of the drill rod by the rotary drilling rig, S110B may include: and responding to a third operation instruction of an operator, and acquiring a fourth position of the power head on the mast. The step of obtaining the first position of the power head on the mast may refer to the step of responding to the first operation instruction of the operator, which is not described herein.
The above method embodiments are further explained below in connection with practical applications.
When the method provided by the embodiment of the application is actually applied, the method can be as follows:
firstly, an operator operates a rotary drilling rig, a drill rod is placed on the ground, and a power head is moved to a pressure platform at the lowest part of the drill rod; operating a 'depth calibration button' button, wherein at the moment, a controller of the rotary drilling rig can respond to the operation of an operator, and the display depth is 0;
then, the operator operates the rotary drilling rig to perform drilling construction. In the process, the controller of the rotary drilling rig can be applied to the S100-S120, and the depth of the drill bit is displayed in real time and is changed along with the drilling of a drill rod;
when the operator finds that the length of the drill rod is insufficient or overlong, the operator can operate a button of a depth calibration button firstly and then operate the rotary drilling rig to extend or shorten the drill rod; after the operation is finished, an operator can operate the 'depth calibration button' button again, the controller of the rotary drilling rig can respond to the operation of the operator, calculate the second relative displacement of the power head and the mast, and obtain the accurate bit depth in real time by the current first relative displacement of the second relative displacement compensation value.
When the power head is required to be moved to the uppermost pressurizing table to continue drilling construction, after the power head is ensured to be pressed to the uppermost pressurizing table, an operator can operate a depth calibration button, and the displayed depth can be restored to the current hole depth and measurement is continued;
if the operator needs to move the power head from the uppermost compression station to the lower two "L-bars" for a drill lifting operation, the operator may: first, when the power head is operated downward from the uppermost pressurizing table preparation, the "depth calibration button" is operated once; then, after confirming that the power head has reached the L-shaped key bar and is successfully locked, the depth calibration button is operated once again.
It is understood that in practical application, a user can complete the measurement of the depth of the drill bit through one-key operation, and the method is simple and practical, and further increases misoperation protection and improves safety.
