[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0022] Reference Figure 1-4 , a stable drilling device with an anti-slip mechanism comprises a drilling and coring machine 1, a drill tube 2 is arranged inside the drilling and coring machine 1, and a first connecting block 3 is connected to the top of the drill tube 2. The connection method and drilling principle of the drilling and coring machine 1 and the drill tube 2 are prior arts, and no further description is given here. A first threaded rod 4 is connected to the side of the first connecting block 3 through a bearing, and an arc block 5 is symmetrically sleeved on the outer side of the first threaded rod 4, and the interior of the arc block 5 is connected through a vertical rod 6 and a clamping plate 7. Two groups of external threads in opposite directions are provided on the outer surface of the first threaded rod 4, and a thread groove matched with the first threaded rod 4 is provided inside the arc block 5, so that when the first threaded rod 4 rotates, the two groups of arc blocks 5 can move in opposite directions. In addition, a rectangular groove matched with the vertical rod 6 is provided on the top of the drill tube 2 to meet the lateral movement requirement of the vertical rod 6, and a receiving groove 8 matched with the clamping plate 7 is provided on the inner wall of the drill tube 2.
[0023] Further, see Figure 2 It can be seen that there are grooves inside the arc blocks 5, and a cross bar 12 is inserted into the grooves. The end of the cross bar 12 is connected to the second connecting block 11, and the bottom end of the second connecting block 11 is connected to the upper side of the drill tube 2. When in use, the second connecting block 11 and the cross bar 12 cooperate with each other to achieve the guidance of the two groups of arc blocks 5 to ensure the stable movement of the two groups of arc blocks 5.
[0024] Further, see Figure 3 It can be known that the side of the first threaded rod 4 away from the first connecting block 3 is connected to the rotating block 10, and the outer surface of the rotating block 10 is evenly distributed with anti-slip particles. Through the mutual cooperation of the rotating block 10 and the anti-slip pattern, the staff can quickly rotate the first threaded rod 4, thereby effectively improving the convenience of the device during use.
[0025] Further, see Figure 3 and Figure 4 It can be known that the rubber plate 9 is glued to the side where the clamping plates 7 are close to each other, and the outer surface of the rubber plate 9 is provided with anti-skid grooves. The mutual cooperation between the rotating block 10 and the anti-skid grooves can ensure the limiting effect of the core block.
[0026] Further, see Figure 3 and Figure 4It can be known that a connecting groove adapted to the vertical rod 6 is opened inside the arc block 5, a second threaded rod 13 is inserted inside the arc block 5, and a connecting strip 14 is connected to the end of the second threaded rod 13, and a slot adapted to the second threaded rod 13 is opened inside the vertical rod 6. When in use, the vertical rod 6 can be easily removed from the inside of the arc block 5 through the mutual cooperation of the second threaded rod 13 and the connecting strip 14, so that the staff can replace the damaged splint 7 conveniently.
[0027] Further, see Figure 4 It can be known that there are two groups of second threaded rods 13, and the two groups of second threaded rods 13 are symmetrically distributed about the central axis of the arc block 5. During use, the two groups of second threaded rods 13 inserted inside the arc block 5 can effectively improve the tightness of the vertical rod 6 in the arc block 5.
[0028] Further, see Figure 4 It can be seen that the outer side of the vertical rod 6 is symmetrically connected to the limit strip 15, and the interior of the arc block 5 is provided with a positioning groove adapted to the limit strip 15. When in use, the convenience of connecting the vertical rod 6 and the arc block 5 can be achieved through the mutual cooperation of the limit strip 15 and the positioning groove.
[0029] Working principle: When the utility model is in use, the staff can first transfer the device to the area that needs to be drilled, and then start the core drilling machine 1, so that the drill tube 2 can continuously rotate and drill downward to achieve the work of coring. After the drill tube 2 drills to the specified depth, the staff can stop starting the core drilling machine 1, and then manually rotate the rotating block 10, thereby driving the first threaded rod 4 to rotate at the same time, so that the first threaded rod 4 and the arc block 5 are threadedly matched, so that the two groups of arc blocks 5 are forced to move in opposite directions, that is, the vertical rod 6 and the clamping plate 7 are also close to each other, so that the drill tube can be moved. 2 is clamped and fixed, so as to prevent the core block from falling off from the drill tube 2. Then the staff can start the core drilling machine 1 again, so as to pull the drill tube 2 out of the borehole. At this time, the staff can push the core drilling machine 1 to an area away from the drill hole, and then the staff can reversely rotate the rotating block 10, so that the two groups of arc blocks 5 can move toward each other again to release the fixing operation of the core block. At this time, the core block inside the drill tube 2 will fall down due to gravity, and then the staff can send the core block to the designated area for detection. The above is the entire working principle of the utility model.

Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
