An embodiment of the present disclosure further provides a method for measuring a real-time hole depth of a roller cone drill for a strip mine during drilling, as shown in fig. 2, including the following steps:
s1, receiving distance data x uploaded by distance measuring device in real timet；
Wherein the distance data xtReflecting the distance between the top end of the drill frame and the pressurizing trolley, and the distance measuring device can be arranged on the drillThe top of the frame or the frame is arranged on the pressurizing trolley and is used for measuring the distance between the top of the drill frame and the pressurizing trolley in real time, and when the pressurizing trolley moves, the distance data measured by the distance measuring device changes along with the distance data;
s2, receiving the number data m of the drill rods on the current pressurizing trolley;
since the number of the drill rods connected to the pressurizing trolley is uncertain before the drilling operation of the drilling machine is started, for example, the number of the drill rods connected to the pressurizing trolley may be 0, 1 or 2, the number of the connected drill rods needs to be input into the system in advance, and in one embodiment, the step can be directly input after a specific situation is obtained through visual observation of a driver (for example, directly input through a physical button connected to the control host or input through a touch screen).
S3: receiving the number n of connecting rod instructions;
when a roller-cone drilling machine performs drilling operation, a deep hole is limited by the length of a drill rod, the operation of extension rod is often required, a pressurizing trolley ascends to connect two drill rods end to end and then continuously descend to drill, and an extension rod signal is sent to a system once during each extension rod operation.
S4, reading height data b of a drill frame, chassis height data c of a drilling machine, length data a of a drill rod, short-circuit joint length data p of the drill rod, length data q of a drill bit and thickness data r of a pressurizing trolley, wherein the height data b of the drill frame, the length data a of the drill rod, the short-circuit joint length data p of the drill bit, the length data q of the drill bit and the thickness data r of the pressurizing trolley are known data; the height data c of the chassis of the drilling machine is obtained through measurement;
the height data b of the drill frame, the length data a of the drill rod, the length data p of the short joint, the length data q of the drill bit and the thickness data r of the pressurizing trolley are all known data; the drilling machine chassis height data c are obtained through measurement. The height c of the drilling machine chassis is the distance from the bottom end of the drilling rig to the ground, and the drilling machine needs to support the platform surface by using a jack before operation, so that the chassis height c in each operation is not a fixed value, the chassis height c needs to be recorded in a measuring mode, the height b of the drilling rig and the length a of the drill rod are fixed values, and the data can be input into a system through input and output equipment (including but not limited to an external keyboard). In one embodiment, a second distance measuring device can be arranged at the bottom of the drilling machine and used for measuring the height c of a chassis of the drilling machine, and data measured by the second distance measuring device is uploaded to a server or a control host computer through a 485 serial port.
S5, calculating the drilling depth H according to the following formula:
H＝xt+r+p+q+a*m+a*n-b-c。
referring to fig. 3, the calculation principle is as follows: x is the number oftThe sum of the thickness r of the pressurizing trolley, the length p of the drill rod short-circuit joint, the lengths a x m of the m drill rods and the length a x n of the changing rod is the length from the top end of the drill frame to the tail end of the drill bit, and the drilling depth can be obtained by subtracting the distance b + c from the top end of the drill frame to the ground by the length.
As an alternative embodiment, the present embodiment may selectively configure the distance measuring device and the second distance measuring device as one of a rope displacement sensor, a laser range finder, a UWB positioning device, or a radar range finder. Fig. 3 shows an installation state of the device using a pull-cord displacement sensor as an example, and it is noted that the distance data x in the present application is used as the datatThe distance between the top end of the drilling rig and the pressurizing trolley is shown, when the pull rope displacement sensor is fixed in a side line outgoing mode, a part of distance (the distance is out of the height range of the drilling rig) exists between the line outlet and the top end of the drilling rig, so that the distance needs to be compensated when the equipment is installed, for example, the length of a connecting piece (not belonging to a component in the pull rope displacement sensor) between a steel wire rope of the pull rope displacement sensor and the pressurizing trolley is equal to the distance between the line outlet of the pull rope displacement sensor and the top end of the drilling rig. For another situation, when the fixing mode of the stay cord displacement sensor is bottom wire outgoing, the wire outlet is directly attached to the top end of the drill frame, so that a connecting piece is not needed (or the connection is not needed)The length of the piece is 0). In another embodiment, when the distance measuring device selects the laser distance measuring instrument, only the distance between the light outlet of the laser distance measuring instrument and the reflector at the top of the pressurizing trolley is required to be the distance between the top of the drilling rig and the top of the pressurizing trolley. It should be noted that, in the drawings of the present application, only schematic diagrams of the pull rope displacement sensor are shown, and the installation manner using other distance measuring devices can be installed according to the above description and the basic capability of those skilled in the art, which are not listed in the description of the drawings of the present application.
