Description

Technical Field

[0001] The utility model relates to the technical field of water exploration operation devices, in particular to an auxiliary calibration device for a water exploration operation drill rod. Background Art

[0002] In order to prevent water disasters caused by groundwater intruding into the mine during coal mining, it is necessary to use a drilling rig to conduct water exploration in advance during the excavation of underground tunnels in coal mines. When conducting water exploration, the drilling rig drills holes to explore and release water. In order to meet the drilling requirements of different depths, it is necessary to extend the length of the drill rod by adding drill rods. Traditional drilling rigs use manpower to add drill rods, which is labor-intensive and inefficient. In order to replace manual work to add drill rods, some drilling rigs that can automatically add drill rods have emerged. A Chinese patent with publication number CN118361201A and publication date July 19, 2024 discloses a water exploration device for automatically adding drill rods to coal mines. When adding drill rods, the working drill rod is clamped by a power head, and the drill rod to be added is first sent into the clamp, and then the clamp holding the drill rod to be added moves toward the power head. After the drill rod to be added contacts the working drill rod, the drill rod to be added is fixed to one end of the working drill rod under the clamping of the clamp. After the connection is completed, the clamp releases the drill rod to be added, and the connected drill rod is clamped and driven by the power head to perform water exploration operations through the borehole.

[0003] In order to realize the alignment and calibration of the drill rod to be connected and the working drill rod, the water exploration operation device disclosed in the above patent sets a drill rod support mechanism between the power head and the clamp. When connecting the drill rod, the clamp first sends the drill rod to be connected between the drill rod guide wheels of the drill rod support mechanism, and drives the drill rod to be connected to rise or fall by the rise or fall of the drill rod bracket of the drill rod support mechanism until the drill rod to be connected is aligned with the working drill rod. After the alignment is completed, the clamp re-clamps the drill rod to be connected located in the drill rod support mechanism, and then the clamp holding the drill rod to be connected moves toward the power head. After moving until the drill rod to be connected contacts the working drill rod, the drill rod to be connected is fixed to one end of the working drill rod under the clamping of the clamp.

[0004] The water exploration operation device disclosed in the above patent cannot be clamped and fixed in the drill rod support mechanism after the drill rod to be connected is sent into the drill rod support mechanism, that is, the drill rod support mechanism cannot form a stable support for the drill rod, resulting in that when the clamp re-clamps the drill rod to be connected in the drill rod support mechanism after the centering is completed, the drill rod to be connected is prone to shaking in the drill rod support mechanism, thereby affecting the clamping of the drill rod to be connected in the drill rod support mechanism by the clamp and affecting the centering and calibration effect of the drill rod to be connected and the working drill rod. The drill rod to be connected needs to be sent into the clamp first during the alignment and calibration, and the clamp then sends the drill rod to be connected into the drill rod support mechanism. After the drill rod support mechanism completes the alignment of the drill rod to be connected and the working drill rod, the clamp re-clamps the drill rod to be connected in the drill rod support mechanism, and finally completes the connection and fixation between the drill rod to be connected and the working drill rod under the clamping of the clamp. This makes the drill rod alignment and calibration of the water exploration operation device and the entire drill rod connection process complicated, and the work efficiency of the water exploration operation drilling construction is difficult to guarantee.

After the drill rod to be added sent into the drill rod supporting groove falls on the arc section of the drill rod calibration frame in the drill rod supporting groove, the arc center of the arc section and the axis center of the drill rod to be added are in a coaxial state.

In this embodiment, the arc segment 221 is a circular arc segment, and the arc center of the arc segment 221 is coaxially arranged with the clamping center of the power head of the drilling rig for water exploration operation, and the two side baffles 212 of the drill rod supporting groove 21 are both installed with a first telescopic cylinder 23 that can slide along the side baffles 212, and the telescopic end of each first telescopic cylinder 23 is rotatably installed with a first clamping wheel 24 that can contact the drill rod to be connected. In this embodiment, a first telescopic cylinder 23 is installed on each of the two side baffles 212 of the drill rod support groove 21, and a first clamping wheel 24 is rotatably installed on each first telescopic cylinder 23. A total of two first clamping wheels 24 are provided, and the two first clamping wheels 24 are arranged opposite to each other.

[0032] When the drill rod to be connected that enters the drill rod supporting groove 21 falls on the arc segment 221 of the drill rod calibration frame 22 and fits with the arc segment 221, the arc center of the arc segment 221 can be coaxial with the axis center of the drill rod to be connected, and the first telescopic cylinder 23 can slide along the side baffle 212 of the drill rod supporting groove 21 until the first clamping wheel 24 presses the drill rod to be connected onto the arc segment 221 of the drill rod calibration frame 22, and the clamped drill rod to be connected is clamped and fixed between the first clamping wheel 24 and the arc segment 221 of the drill rod calibration frame 22.

[0033] When using the water exploration drill rod auxiliary calibration device of this embodiment to perform auxiliary centering calibration of the drill rod, the water exploration drill rod auxiliary calibration device is installed on one side of the power head of the water exploration drilling rig, and during installation, the arc center of the arc segment 221 of the drill rod calibration frame 22 and the clamping center of the power head of the drilling rig are in a coaxial setting state. Afterwards, a manipulator or other drill rod conveying device is used to send the drill rod to be connected into the drill rod supporting groove 21 of the drill rod support 2. After the drill rod to be connected sent into the drill rod supporting groove 21 falls on the arc segment 221 of the drill rod calibration frame 22 in the drill rod supporting groove 21, the arc center of the arc segment 221 and the axis center of the drill rod to be connected are in a coaxial state. Because the clamping center of the power head of the drilling rig and the axis center of the working drill rod clamped in the power head are coaxially arranged, when the arc center of the arc segment 221, the clamping center of the power head and the axis center of the drill rod to be connected are all in a coaxial state, the drill rod to be connected can be in a coaxial alignment state with the working drill rod, that is, after the drill rod to be connected sent into the drill rod supporting groove 21 falls on the arc segment 221 of the drill rod calibration frame 22, the alignment and calibration of the drill rod to be connected and the working drill rod can be achieved. After the centering calibration is completed, the first telescopic cylinder 23 slides along the side baffle 212 of the drill rod support groove 21 until the first clamping wheel 24 installed on the first telescopic cylinder 23 presses the drill rod to be connected onto the arc segment 221 of the drill rod calibration frame 22, and the drill rod to be connected is clamped and fixed between the first clamping wheel 24 and the arc segment 221 of the drill rod calibration frame 22, so that a stable support can be formed for the drill rod to be connected when the drill rod is connected. After the drill rod to be connected is clamped and fixed between the first clamping wheel 24 and the arc segment 221 of the drill rod calibration frame 22, the drill rod support 2 moves along the base 1 toward the power head of the drilling rig, and after moving until the drill rod to be connected contacts the working drill rod, one end of the drill rod to be connected is connected and fixed to the working drill rod under the clamping of the drill rod auxiliary calibration device for water exploration operations.

[0034] In order to facilitate the insertion of the drill rod to be connected into the drill rod support groove 21, Figure 1 , 3 As shown in FIG. 5 , the drill rod supporting groove 21 is gradually narrowed from top to bottom, that is, the two side baffles 212 of the drill rod supporting groove 21 are arranged obliquely.

[0035] Regarding the specific structure of the drill rod calibration frame 22, as shown in FIG. Figure 1-4 As shown, the drill rod calibration frame 22 includes two support segments 222 fixedly mounted on the bottom plate 211 of the drill rod support slot 21, and the arc segment 221 is fixedly mounted between the two support segments 222. In order to stably support the drill rod to be connected, two parallel drill rod calibration frames 22 are provided in this embodiment.

[0036] In order to form a more stable clamping and support for the added drill pipe, Figure 1 , 2As shown, a second clamping wheel 25 is rotatably mounted on the bottom plate 211 of the drill rod supporting groove 21, and a reset spring 261 is installed between the second clamping wheel 25 and the bottom plate 211 of the drill rod supporting groove 21. Under the action of the reset spring 261, at least part of the second clamping wheel 25 can be located above the arc segment 221 of the drill rod calibration frame 22. In this embodiment, under the action of the reset spring 261, all the second clamping wheels 25 can be located above the arc segment 221 of the drill rod calibration frame 22; when the drill rod to be connected that enters the drill rod supporting groove 21 falls on the arc segment 221 of the drill rod calibration frame 22, the drill rod to be connected can press down the second clamping wheel 25, and the drill rod to be connected can be clamped and fixed between the first clamping wheel 24 and the second clamping wheel 25, so that the first clamping wheel 24, the second clamping wheel 25, and the arc segment 221 of the drill rod calibration frame 22 form a more stable support for the drill rod to be connected.

[0037] like Figure 1 , 2 As shown, in order to make the second clamping wheel 25 rise or fall in the vertical direction (i.e., perpendicular to the bottom plate 211), a guide rod 262 is slidably mounted on the bottom plate 211 of the drill rod support groove 21, the reset spring 261 is sleeved outside the guide rod 262, a second clamping wheel frame 263 is fixedly mounted on the top of the guide rod 262, the second clamping wheel 25 is rotatably mounted on the second clamping wheel frame 263, one end of the reset spring 261 is fixed on the second clamping wheel frame 263, and the other end is fixed on the bottom plate 211 of the drill rod support groove 21. In this embodiment, a through hole is provided in the bottom plate 211 of the drill rod support groove 21, and the guide rod 262 is penetrated and slidably mounted in the through hole.

[0038] In order to improve the clamping effect of the first clamping wheel 24 and the second clamping wheel 25 on the drill rod to be connected, in this embodiment, the axes of the first clamping wheel 24 and the second clamping wheel 25 are parallel to the drill rod to be connected which is clamped on the arc segment 221 of the drill rod calibration frame 22; the wheel surfaces of the first clamping wheel 24 and the second clamping wheel 25 can be tangent to the outer surface of the drill rod to be connected which is clamped on the arc segment 221 of the drill rod calibration frame 22.

[0039] like Figure 1 , 3-5, in order to realize the sliding of the first telescopic cylinder 23 along the side baffles 212 of the drill rod support groove 21, the second telescopic cylinder 27 is fixedly installed on both side baffles 212 of the drill rod support groove 21, and the first telescopic cylinder 23 is fixedly installed at the telescopic end of the second telescopic cylinder 27. When the second telescopic cylinder 27 is extended or retracted, it drives the first telescopic cylinder 23 to slide along the side baffles 212 of the drill rod support groove 21. In this embodiment, the cylinder body of the second telescopic cylinder 27 is fixedly installed on the two side baffles 212 of the drill rod support groove 21, the piston rod of the second telescopic cylinder 27 is arranged parallel to the side baffles 212 of the drill rod support groove 21, and the cylinder body of the first telescopic cylinder 23 is fixedly installed on the piston rod of the second telescopic cylinder 27. In order to facilitate the installation of the first telescopic cylinder 23, in this embodiment, a slide groove 2121 is provided on the side baffles 212 of the drill rod support groove 21, and the first telescopic cylinder 23 is slidably installed in the slide groove 2121.

[0040] In this embodiment, the first telescopic cylinder 23 and the second telescopic cylinder 27 are telescopic cylinders, but other conventional telescopic cylinders such as hydraulic cylinders and telescopic electric cylinders may also be used.

[0041] In order to realize the sliding of the drill rod support 2 along the base 1, as Figure 1 , 3 As shown in Figures 4 and 5, a driving motor 11 is fixedly mounted on the base 1, a lead screw 12 is fixedly mounted on the output end of the driving motor 11, a slider 28 is fixedly mounted on the lower part of the bottom plate 211 of the drill rod support groove 21, and the slider 28 is threadedly connected to the lead screw 12. The driving motor 11 is started to drive the lead screw 12 to rotate, and the rotation of the lead screw 12 drives the slider 28 to slide along the lead screw 12. The sliding of the slider 28 drives the drill rod support groove 21 to slide along the lead screw 12, and then drives the drill rod support 2 to slide along the base 1. In order to enable the drill rod support 2 to slide more smoothly along the base 1, a guide rail 13 is fixedly mounted on the base 1 in this embodiment, and a guide block 29 is fixedly mounted on the lower part of the bottom plate 211 of the drill rod support groove 21, and the guide block 29 is sleeved on the guide rail 13 and can slide along the guide rail 13. When the slider 28 slides along the lead screw 12, the guide block 29 slides along the guide rail 13.

[0042] When using the water exploration drill rod auxiliary calibration device of this embodiment to perform auxiliary centering calibration of the drill rod, the water exploration drill rod auxiliary calibration device is installed on one side of the power head of the water exploration drilling rig, and during installation, the arc center of the arc segment 221 of the drill rod calibration frame 22 and the clamping center of the power head of the drilling rig are in a coaxial setting state. The second telescopic cylinder 27 performs a telescopic action to make the first telescopic cylinder 23 slide upward along the side baffle 212 of the drill rod support groove 21, and then a manipulator or other drill rod conveying device is used to send the drill rod to be connected into the drill rod support groove 21 of the drill rod bracket 2. After the drill rod to be connected sent into the drill rod support groove 21 falls on the arc segment 221 of the drill rod calibration frame 22 in the drill rod support groove 21, the drill rod to be connected presses the second clamping wheel 25 downward, and the arc center of the arc segment 221 and the axis center of the drill rod to be connected are in a coaxial state, and the drill rod to be connected and the working drill rod clamped by the power head are in a coaxial centering state, thereby completing the centering calibration of the drill rod to be connected and the working drill rod. After the centering calibration is completed, the first telescopic cylinder 23 telescopes according to the size of the drill rod to be connected so that the first clamping wheel 24 installed on the first telescopic cylinder 23 can contact and press the drill rod to be connected. After the first telescopic cylinder 23 is adjusted to a length suitable for the drill rod to be connected through the telescopic action, the first telescopic cylinder 23 slides downward along the side baffle 212 of the drill rod support groove 21 until the first clamping wheel 24 installed on the first telescopic cylinder 23 presses the drill rod to be connected onto the arc segment 221 of the drill rod calibration frame 22. The drill rod to be connected is clamped and fixed between the first clamping wheel 24, the second clamping wheel 25 and the arc segment 221 of the drill rod calibration frame 22, so that a stable support can be formed for the drill rod to be connected when the drill rod is connected. After the drill rod to be connected is clamped and fixed between the first clamping wheel 24, the second clamping wheel 25 and the arc segment 221 of the drill rod calibration frame 22, the driving motor 11 is started to drive the screw 12 to rotate and then drive the slider 28 to slide along the screw 12, and then drive the drill rod support 2 to move along the base 1 toward the power head of the drilling rig, and move until the drill rod to be connected contacts the working drill rod, and then the drill rod to be connected is fixed to one end of the working drill rod under the clamping of the water exploration operation drill rod auxiliary calibration device. After the connection is completed, the first telescopic cylinder 23 slides upward and then releases the first clamping wheel 24, the second clamping wheel 25 and the arc segment 221 of the drill rod calibration frame 22 for the connection of the drill rod to be connected, and the water exploration operation drill rod auxiliary calibration device loosens the drill rod to be connected, and the connected drill rod is clamped and driven by the power head to perform water exploration through the drilling hole.
