Description

Technical Field

[0002] Coal mines often have to drill various boreholes when conducting underground production. Some boreholes can be hundreds of meters or even thousands of meters deep, which are used for gas extraction or to insert explosives for blasting. However, the ground stress underground is complex, and it is easy for the borehole to collapse and become blocked, which is inevitable. For example, when inserting explosives, it is necessary to first probe the borehole to confirm that there is no blockage before plugging the explosives.

Figure 4 This is a schematic diagram showing that the angle between the exploration line 14 and the horizontal plane is 30°. Figure 5 This is a schematic diagram showing that the angle between the exploration line 14 and the horizontal plane is 60°.

[0023] A hole-finding line 14 is placed on the reel 22 , and the hole-finding line 14 passes between the first driving line wheel 7 and the second driving line wheel 8 of the guide mechanism 4 and between the first driven line wheel 9 and the second driven line wheel 10 .

[0024] The wire reel 22 includes a second bracket 15 and a rotating frame 16. The second bracket 15 is a triangular bracket structure, including a bracket cross plate, a first inclined plate and a second inclined plate connected in sequence at the head and tail ends. The first inclined plate and the second inclined plate are provided with corresponding first through-holes and second through-holes. A central axis is provided at the connection between the first inclined plate and the second inclined plate. The rotating frame 16 includes a circular frame body. Three groups of rectangular frames passing through the center of the circle are provided inside the circular frame body. A center sleeve is provided at the center position of the circular frame body. The rectangular frame is welded on the circular sleeve. The two ends of the rectangular frame are provided on the circumference of the circular frame body to constrain the high-strength glass fiber drilling wire reel. The drilling wire reel is transported by starting the motor to drive the center sleeve forward and reverse. The rotating frame 16 is sleeved on the central axis through the center sleeve; the lower left and lower right parts of the circular frame body pass through the first through-hole and the second through-hole respectively, and two walking wheels 17 are provided at the bottom ends of the bracket cross plate. The walking wheels 17 can move the wire reel 22 to a suitable position.

[0025] The first bracket 1 includes a support column 18, and the upper part of the support column 18 is provided with a mounting groove 19 extending downwardly. The top cylinder 2 is installed in the mounting groove 19, and the top of the mounting groove 19 is provided with an upper cover plate 20. The middle part of the upper cover plate 20 is provided with a through hole, and the piston rod of the top cylinder 2 passes through the through hole. The cylinder switch 21 of the top cylinder 2 is arranged on the left wall of the support column 18, and the piston rod end of the top cylinder 2 is installed with a top plate. The middle part of the support column 18 is provided with a mounting hole for installing left and right through-holes, and the guide mechanism 4 is installed in the mounting hole. Ear plates are provided on the front and back sides of the bottom of the guide rod body 6, and mounting rods are installed in the mounting hole front and back. The ear plates are sleeved on the mounting rod, so that the guide mechanism 4 rotates along the mounting rod; the bottom of the support column 18 is provided with a bottom plate, and a number of reinforcing ribs are provided around the bottom plate and the support column 18 bracket to further improve the stability of the support column 18 and ensure the smooth progress of the exploration operation. When the present application is used in practice, first, a mining drilling and probing device is installed in the tunnel 24. Specifically, the first bracket 1 is set at the corresponding position of the borehole 25 to be probed in the tunnel 24. The cylinder switch 21 of the top cylinder 2 is controlled to support the piston rod of the top cylinder 2 on the top plate of the tunnel 24 to ensure the stability of the first bracket 1. Then, the wire reel 22 is moved to the left side of the first bracket 1 so that the probing line 14 extends into the guide tube 6 and passes through the active component and the driven component. Then, the mining drilling and probing device is adjusted so that the probing line 14 is aligned with the borehole. Specifically, the first threaded rod 14 is adjusted by rotating the rotating sleeve 11. 12 and the length of the second threaded rod 13 are used to adjust the inclination angle of the guide tube 6, so that the guide ball 26 at the drilling end of the drilling line 14 is aligned with the drill hole 25 to be drilled, and at the same time, the center line of the guide tube 6 coincides with the center line of the drill hole 25; finally, the mining drilling and drilling device is started to make the drilling line 14 enter the drill hole 25 for drilling. Specifically, the pneumatic motor 3 is started to drive the second rotating shaft to rotate and then drive the second active wire wheel 8 to rotate. The clamping force drives the drilling line 14 to enter the drill hole 25 for drilling. The drilling line is made of high-strength glass fiber, and the high-strength drilling line body can remain straight after extending out of the reel. When the exploration line 14 can be advanced to the depth of the borehole 25 (the length of the exploration line 14 extending into the borehole is consistent with the actual drilling depth of the borehole), the mining drilling exploration device is reversed, the exploration line 14 is retracted, and the mining drilling exploration device is adjusted again to align the exploration line 14 with the next borehole; when the exploration hole cannot be advanced to the depth of the borehole 25, it indicates that a blockage or collapse occurs in the borehole 25, and the borehole 25 needs to be penetrated. After the penetration is completed, the exploration is continued until the exploration line 14 is advanced to the depth of the borehole 25, and the mining drilling exploration device is reversed again, the exploration line 14 is retracted, and the mining drilling exploration device is adjusted again to align the exploration line 14 with the next borehole; and this cycle is repeated until the exploration operation of all boreholes is completed.

[0026] During the specific operation of the present application, the first bracket 1 is set at the corresponding position of the borehole 25 to be drilled in the tunnel 24, and the cylinder switch 21 of the top cylinder 2 is used to support the piston rod on the top wall of the tunnel 24. Then, the reel 22 is moved to the left side of the first bracket 1, so that the drilling line 14 passes through the guide mechanism 4. The top cylinder 2 can ensure the stability of the first bracket 1, thereby ensuring the smooth progress of the drilling operation. The present application adjusts the length of the first threaded rod 12 and the second threaded rod 13 by rotating the rotating sleeve 11, thereby adjusting the angle of the guide mechanism 4, so that the guide ball 26 at the drilling end of the drilling line 14 is aligned with the drill hole 25 to be drilled, thereby making the present application applicable to various drill holes 25, thereby improving applicability. The present application is simple and convenient to operate, and uses the pneumatic motor 3 to cooperate with the guide mechanism 4 to transport the drilling line 14, thereby achieving the purpose of automatic drilling, reducing labor intensity, and improving underground construction efficiency.
