[0036] Example:
[0037] Reference Figures 1-6 This utility model provides a drilling device for water control in coal mines with protective functions: it includes two first columns 1 and two second columns 2. A protective plate 3 is fixedly connected to the top side of the first columns 1. The surface of the protective plate 3 is fixedly connected to the second columns 2, providing shielding protection. During drilling in coal mine roadways, the protective plate 3 prevents falling objects from hitting the drilling motor 8 and workers. A lifting frame 4 is provided on the surface of the two first columns 1. A sliding groove 5 is formed on the surface of the lifting frame 4, and a baffle 6 is slidably connected to the inner wall of the sliding groove 5. An electric push rod 7 is fixedly connected to the lower surface of the protective plate 3. The output end of the push rod 7 is fixedly connected to the baffle 6. The upper surface of the lifting frame 4 is fixedly connected to the first hydraulic rod 11. The lower surface of the protective plate 3 is fixedly connected to the first hydraulic rod 11. The upper surface of the lifting frame 4 has two symmetrically distributed sliding holes 12. The inner wall of the sliding hole 12 is slidably connected to the first column 1. Before drilling, the electric push rod 7 extends and slides the baffle 6 downward, so that the baffle 6 slides with the sliding groove 5, and then the bottom of the baffle 6 abuts against the ground. During drilling, mud and sand will splash. The splashed mud and sand is blocked by the baffle 6, making it less likely for the workers to be splashed with mud and sand, thus improving the safety of the workers.
[0038] In this embodiment, refer to Figure 1 , Figure 2 and Figure 3A drilling motor 8 is fixedly connected to the upper surface of the lifting frame 4, and a drill rod 9 is rotatably connected to the lower surface of the lifting frame 4. The output end of the drilling motor 8 is fixedly connected to the drill rod 9, and a drill bit 10 is provided on the lower surface of the drill rod 9. The first hydraulic rod 11 extends, causing the first column 1 to slide with the sliding hole 12, thus restricting the movement of the lifting frame 4 in the opposite direction. The drilling motor 8 drives the drill rod 9 to rotate, and the drill rod 9 drives the drill bit 10 to rotate, thus performing drilling through the drill bit 10.
[0039] In this embodiment, refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 The upper surface of the baffle 6 is inlaid with a sliding sleeve 13. The sliding sleeve 13 has a mating hole 14 inside. A connecting rod 15 is slidably connected to the inner wall of the sliding sleeve 13. The lower surface of the protective plate 3 is fixedly connected to the connecting rod 15. One end of the connecting rod 15 is fixedly connected to an anti-detachment head 16. The inner wall of the mating hole 14 is slidably connected to the anti-detachment head 16. During the lifting and lowering process of the baffle 6, the connecting rod 15 slides with the sliding sleeve 13, and the mating hole 14 slides with the anti-detachment head 16, thereby restricting the movement direction of the baffle 6. The anti-detachment head 16 is not easy to leave the sliding sleeve 13, making it difficult for the connecting rod 15 to separate from the sliding sleeve 13.
[0040] In this embodiment, refer to Figure 1 , Figure 2 and Figure 6 The upper surfaces of the two first columns 1 and the two second columns 2 are all fixedly connected with top rods 17, and the upper surfaces of the top rods 17 are fixedly connected with conical heads 18. The lower surfaces of the two first columns 1 and the two second columns 2 are all fixedly connected with second hydraulic rods 19. First, the two first columns 1 and the two second columns 2 are erected, and the second hydraulic rods 19 are extended, causing the first columns 1 and the two second columns 2 to move upward, which in turn causes the top rods 17 and the conical heads 18 to move upward, and then causes the conical heads 18 to insert into the top of the coal mine roadway, so that the two first columns 1 and the two second columns 2 are pressed tightly together, and thus the two first columns 1 and the two second columns 2 are not easy to move.
[0041] Working principle: Step 1, move the device into the coal mine roadway and erect the two first columns 1 and the two second columns 2;
[0042] Step 2: The second hydraulic rod 19 extends, causing the first column 1 and the two second columns 2 to move upward, which in turn causes the top rod 17 and the conical head 18 to move upward, and the conical head 18 to insert into the top of the coal mine roadway, so that the two first columns 1 and the two second columns 2 are pressed tightly together, making it difficult for the two first columns 1 and the two second columns 2 to move.
[0043] Step 3: Before drilling, the electric push rod 7 extends and slides the baffle 6 downward, causing the baffle 6 to slide with the sliding groove 5. As a result, the bottom of the baffle 6 touches the ground. During drilling, mud and sand will splash. The splashed mud and sand is blocked by the baffle 6, making it less likely for workers to be splashed with mud and sand, thus improving the safety of workers.
[0044] Step four: The first hydraulic rod 11 extends, causing the first column 1 to slide against the sliding hole 12, restricting the movement of the lifting frame 4 in the opposite direction. The drilling motor 8 drives the drill rod 9 to rotate, and the drill rod 9 drives the drill bit 10 to rotate, so that drilling is performed through the drill bit 10.
[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
