Description

Technical Field

[0001] The utility model relates to the technical field of geological survey, in particular to a mining intrinsically safe drilling rig hole opening and orientation instrument. Background Art

[0002] In the process of mining mineral resources, drilling rigs are generally used to drive the drills underground to conduct drilling exploration and obtain geological data to find out the underground geology and mineral resources. Some current drilling rigs still have the problem of drilling deviation, which requires the assistance of drilling directional devices.

[0003] In the prior art, for example, a Chinese patent with the authorization announcement number CN206830051U proposes a mining intrinsically safe drilling rig hole opening directional instrument, in which the drill rod is inserted from the movable tube into the fixed tube, and the pre-drilling is performed by sliding the movable tube along the axial direction of the fixed tube. When drilling along the pre-drilling position, the guiding effect of the movable tube is used to prevent the whole from deviating. When the drill rod deviates relative to the movable tube, its rotating rod portion will counteract the ball of the mandrel assembly, and the ball tends to move inward under the restoring effect of the tension spring. In this way, the degree of deviation of the drill rod is controlled, thereby realizing the hole opening directional function. However, during exploration, the surface is generally uneven or has a slope, and the fixed tube in the above-mentioned directional instrument is fixed to the ground by a fixed pressure plate, and does not have a leveling function. If a vertical hole needs to be drilled, then after the above-mentioned directional instrument is fixed on an uneven ground or on a sloped ground, the fixed tube may deviate, thereby causing the drilling hole to deviate.

[0069] The fine-tuning mechanism can fine-tune the oriented plate 2 to further improve the horizontality of the oriented plate 2, thereby improving the verticality of the oriented tube 4. Moreover, when drilling, if the oriented plate 2 is tilted, the oriented plate 2 can also be adjusted by the fine-tuning mechanism to keep the oriented plate 2 horizontal and the oriented tube 4 vertical.

[0070] like Figure 1 As shown, further, a through hole 12 and a plurality of fixing holes 11 are provided on the substrate 1 , the axis of the through hole 12 coincides with the axis of the connecting hole 22 , and the plurality of fixing holes 11 are arranged around the through hole 12 .

[0073] like Figure 1 and Figure 3 As shown, further, a sleeve 21 is fixedly connected to the upper surface of the oriented plate 2, and the axis of the sleeve 21 coincides with the axis of the connecting hole 22;

[0076] The spiral blades 41 can assist the directional pipe 4 in drilling forward, making it easier for the directional pipe 4 to drill into the ground.

[0077] With the utility model, the base plate 1 is first fixed on the original ground, and then the bubble in the level 5 is observed to be centered. If it is not centered, the oriented plate 2 is not in a horizontal state, and the oriented plate 2 needs to be leveled. First, the fixing bolts 7 on the two sliders 6 are loosened at the same time, and the two corresponding fasteners 9 are loosened to release the locks of the two sliders 6, and the locks between the corresponding hinged ears 2 and the double hinged ears are released. Then, the two unlocked sliders 6 are moved into or out of the base plate 1 at the same time. The sliders 6 drive the lower ends of the second support rods 32 to move into or out of the base plate 1, and the inclinations of the corresponding two leveling support rods 3 will change accordingly. The oriented plate 2 will rotate upward or downward with the hinge axis on the third side of the oriented plate 2 as the rotating axis. At the same time, the leveling device 5 is observed to be in a horizontal state. Observe the moving direction of the bubble in the level 5 to see if the bubble approaches the center of the level 5, then tighten the fixing bolt 7 on one of the sliders 6 to lock the slider 6, and tighten the corresponding fastener 9 to lock the corresponding hinged ear 2 and the double hinged ear, then loosen the fixing bolt 7 on the third slider 6, and loosen the corresponding fastener 9 to release the lock of the third slider 6, as well as the lock between the corresponding hinged ear 2 and the double hinged ear, and then move the third slider 6 and the previously unlocked slider 6 into or outside the substrate 1 at the same time, and continue to observe the moving direction of the bubble. In this way, by adjusting the inclination of two adjacent leveling support rods 3 at the same time to adjust the horizontality of the oriented plate 2, the verticality of the oriented tube 4 can be ensured.

[0078] After the above operation, if it is necessary to fine-tune the horizontality of the oriented plate 2, the two adjacent knobs 36 must be rotated at the same time. At this time, the knob 36 drives the active bevel gear 35 to rotate, the active bevel gear 35 drives the driven bevel gear 34 to rotate, the driven bevel gear 34 drives the adjusting tube 33 to rotate, the adjusting tube 33 drives the support rod 1 31 to rotate, and the support rod 1 31 extends or retracts along the axial direction of the support rod 2 32, so that the horizontality of the oriented plate 2 can be further improved, thereby improving the drilling accuracy.

[0079] After the directional plate 2 is leveled, the directional tube 4 is rotated by an auxiliary tool, and the directional tube 4 is guided by the casing 21, so that the directional tube 4 can be moved vertically downward, pass through the through hole 12, and drill into the ground. The spiral leaves 41 arranged on the side surfaces of the directional tube 4 can assist the directional tube 4 in drilling, so that the lower end of the directional tube 4 can be drilled into the ground more easily. In this way, the stability of the directional tube 4 can be improved, and the directional tube 4 can be prevented from being deflected during drilling, thereby affecting the drilling accuracy.

[0080] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation modes. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the illustrations shown and described herein.
