Description

Technical Field

[0001] This utility model relates to the field of mining geological surveying and drilling technology, specifically a safety protection device for mining geological surveying and drilling. Background Technology

[0002] The main purpose of mining geological survey drilling is to drill holes in the strata using drilling equipment to extract core samples or obtain geological structure data, providing a scientific basis for the development of mineral resources. During the drilling process, safety protection devices are usually installed above the borehole to ensure drilling efficiency and safety.

[0003] During drilling, sand and debris carried out by the drill bit will splash at high speed as the drill rod rotates. This not only easily scatters on the ground around the borehole, but may also fall back into the borehole. These splashes need to be cleaned manually at regular intervals. If the sand and debris are not cleaned in time, they will accumulate around the borehole, which will not only affect the normal operation of the drill rod, but may also cause equipment jamming due to excessive accumulation. Therefore, a safety protection device for mining geological survey drilling is needed to solve the above-mentioned technical defects. Utility Model Content

[0004] The purpose of this utility model is to provide a safety protection device for mining geological survey drilling, so as to solve the problem of sand and soil accumulation mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a safety protection device for mining geological survey drilling, comprising a fixed pile and a gear ring. The gear ring is machined on the outer wall of the fixed pile. A stepper motor is placed on the left side of the fixed pile. A gear is fixedly connected to the output shaft of the stepper motor. The gear meshes with the gear ring. An inner groove is formed in the middle of the fixed pile. A bracket is supported in the inner groove. A dustproof shell is fixedly connected to the top of the bracket. A drive motor is fixedly connected inside the dustproof shell. A rotating frame is fixedly connected to the output shaft of the drive motor. A first rotating sleeve is movably sleeved in the middle section of the rotating frame. A swing arm is movably connected to the right side of the first rotating sleeve. A second rotating sleeve is movably sleeved to the right side of the swing arm. A spring is fixedly connected to the bottom end of the second rotating sleeve. A brush rod is fixedly connected to the bottom end of the spring. A scraper is fixedly connected to the bottom end of the brush rod.

[0006] As a further technical solution of this utility model, the rotating frame is "U" shaped and the support is "L" shaped.

[0007] As a further technical solution of this utility model, the scraper abuts against the surface of the fixed pile, and the scraper can be disassembled from the brush rod by screws.

[0008] As a further technical solution of this utility model, a set of guide structures are provided on each of the left and right sides of the spring; the guide structure includes an inner rod fixed to the bottom end of the second rotating sleeve, and an outer cylinder is fixedly connected to the top end of the brush rod, and the inner rod and the outer cylinder are fitted together.

[0009] As a further technical solution of this utility model, the bottom end of the bracket is conical, and the bracket is inserted into the ground through the inner groove.

[0010] As a further technical solution of this utility model, four sets of fixing shells are fixedly connected to the top of the fixed pile. A servo motor is installed in each set of fixing shells. A screw is fixedly connected to the output shaft of the servo motor. A threaded block is movably sleeved on the outside of the screw. A positioning block is fixedly sleeved on the top of the threaded block.

[0011] As a further technical solution of this utility model, the outer wall of the threaded block is machined with a limiting groove that slides and connects with the fixed pile, and the positioning block is movably assembled on the surface of the fixed pile.

[0012] As a further technical solution of this utility model, the positioning blocks are provided in four sets, and the positioning blocks are distributed in a ring around the inner groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the safety protection device for mining geological survey drilling not only realizes the automatic cleaning function of sand and soil around the borehole and reduces the hard friction wear of mechanical parts caused by rigid collision, but also realizes the auxiliary positioning of the drill bit;

[0014] (1) By setting up a second rotating sleeve, brush rod, swing arm, bracket, dustproof shell, drive motor, rotating frame, first rotating sleeve, scraper, outer cylinder, inner rod, and spring, the fixed pile is placed above the well hole, so that the drill hole is located between the inner grooves. The bracket is inserted. When the drill rod is inserted into the drilling from the middle of the four sets of positioning blocks, the sand that is constantly splashed upward rolls from the slope of the positioning block to the surface of the fixed pile. The stepper motor drives the gear to rotate, which drives the gear ring to rotate. At the same time, the drive motor is started. When the rotating frame rotates, the first rotating sleeve pulls the swing arm horizontally to swing back and forth as the rotating frame rotates vertically. Since the fixed pile is rotating horizontally, the sand on its surface will be scraped off by the brush rod, realizing the automatic cleaning function of the sand around the drill hole and providing safety protection for the drill rod.

[0015] (2) By setting up a brush rod, spring, scraper, outer cylinder and inner rod, and setting a spring at the bottom of the brush rod, the scraper at the bottom of the brush rod can always be in contact with the surface of the fixed pile. When scraping the fixed pile, the spring and the outer cylinder and inner rod on both sides can reduce the hard friction wear of mechanical parts caused by rigid collision.

[0016] (3) By setting an inner groove, a servo motor, a screw, a threaded block, and a positioning block, the drill rod is inserted into the inner groove. The servo motor in the fixed shell drives the screw to rotate. The rotation of the screw drives the threaded block to move, thereby pushing the positioning block fixed to it to gather towards the center of the inner groove from four directions, avoiding the drill bit from colliding with the edge of the inner groove, and has the function of assisting the positioning of the drill bit.

[0023] Please see Figure 1-4This utility model provides an embodiment of a safety protection device for mining geological survey drilling, comprising a fixed pile 1 and a gear ring 2. The gear ring 2 is machined on the outer wall of the fixed pile 1. A stepper motor 9 is placed on the left side of the fixed pile 1. The output shaft of the stepper motor 9 is fixedly connected to a gear 10, which meshes with the gear ring 2. An inner groove 11 is formed in the middle of the fixed pile 1. A bracket 15 is supported in the inner groove 11. A dustproof shell 16 is fixedly connected to the top of the bracket 15. A drive motor 17 is fixedly connected inside the dustproof shell 16. The output shaft of motor 17 is fixedly connected to a rotating frame 18. The middle section of the rotating frame 18 is movably sleeved with a first rotating sleeve 19. The right side of the first rotating sleeve 19 is movably connected to a swing arm 14. The right side of the swing arm 14 is movably sleeved with a second rotating sleeve 12. The bottom end of the second rotating sleeve 12 is fixedly connected to a spring 23. The bottom end of the spring 23 is fixedly connected to a brush rod 13. The bottom end of the brush rod 13 is fixedly connected to a scraper 20. The rotating frame 18 is "U" shaped, the bracket 15 is "L" shaped, and the scraper 20 abuts against the surface of the fixed post 1. The scraper 20 can be removed and installed from the brush rod 13 by screws.

[0024] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the fixed pile 1 is placed above the well hole, so that the drill hole is located between the inner grooves 11. The bracket 15 is inserted. When the drill rod is inserted into the drilling from the middle of the four sets of positioning blocks 7, the sand that is constantly splashed upward rolls from the slope of the positioning block 7 to the surface of the fixed pile 1. The stepper motor 9 drives the gear 10 to rotate, which drives the gear ring 2 to rotate. At the same time, the drive motor 17 is started. When the rotating frame 18 rotates, the first rotating sleeve 19 pulls the swing arm 14 to swing back and forth as the rotating frame 18 rotates vertically. Since the fixed pile 1 is rotating horizontally, the sand on its surface will be scraped off by the brush rod 13.

[0025] A set of guide structures is provided on each of the left and right sides of the spring 23; the guide structure includes an inner rod 22 fixed at the bottom of the second rotating sleeve 12, an outer cylinder 21 fixedly connected to the top of the brush rod 13, the inner rod 22 and the outer cylinder 21 are fitted together, the bottom of the bracket 15 is conical, and the bracket 15 passes through the inner groove 11 and is inserted to the ground.

[0026] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, a spring 23 is provided at the bottom of the brush rod 13, so that the scraper 20 at the bottom of the brush rod 13 can always be in contact with the surface of the fixed post 1. When scraping the fixed post 1, the rigid friction wear of mechanical parts caused by rigid collision can be reduced by the spring 23 and the outer cylinder 21 and inner rod 22 on both sides.

[0027] Four sets of fixed shells 3 are fixedly connected to the top of the fixed pile 1. A servo motor 4 is installed in each set of fixed shells 3. The output shaft of the servo motor 4 is fixedly connected to a screw 5. A threaded block 6 is movably sleeved on the outside of the screw 5. A positioning block 7 is fixedly sleeved on the top of the threaded block 6. A limiting groove 8 that slides with the fixed pile 1 is machined on the outer wall of the threaded block 6. The positioning block 7 is movably assembled on the surface of the fixed pile 1. There are four sets of positioning blocks 7. The positioning blocks 7 are distributed in a ring around the inner groove 11.

[0028] Specifically, such as Figure 1 and Figure 2 As shown, the drill rod is inserted into the inner groove 11. The servo motor 4 inside the fixed shell 3 drives the screw 5 to rotate. The rotation of the screw 5 drives the threaded block 6 to move, thereby pushing the positioning block 7 fixed thereto to converge towards the center of the inner groove 11 from four directions, avoiding the drill bit from colliding with the edge of the inner groove 11, and has the function of assisting the positioning of the drill bit.

[0029] Working principle: The fixed pile 1 is placed above the borehole, so that the borehole is located between the inner grooves 11. The bracket 15 is inserted. When the drill rod is inserted into the drilling through the middle of the four sets of positioning blocks 7, the drill rod penetrates deep into the inner groove 11. The servo motor 4 in the fixed shell 3 drives the screw 5 to rotate. The rotation of the screw 5 drives the threaded block 6 to move, thereby pushing the positioning blocks 7 fixed to it to gather from four directions towards the center of the inner groove 11, avoiding the drill bit from colliding with the edge of the inner groove 11. It has the function of assisting the positioning of the drill bit. The sand and soil that are constantly splashed upward roll from the slope of the positioning block 7 to the surface of the fixed pile 1. The stepper motor 9 drives the gear 10 to rotate. The movement drives the gear ring 2 to rotate, and simultaneously starts the drive motor 17. When the rotating frame 18 rotates, the first rotating sleeve 19 pulls the swing arm 14 to swing back and forth as the rotating frame 18 rotates vertically. Since the fixed pile 1 rotates horizontally, the sand on its surface will be scraped off by the brush rod 13. The bottom end of the brush rod 13 is equipped with a spring 23, so that the scraper 20 at the bottom end of the brush rod 13 can always be in contact with the surface of the fixed pile 1. When scraping the fixed pile 1, the spring 23 and the outer cylinder 21 and inner rod 22 on both sides can reduce the hard friction wear of mechanical parts caused by rigid collision, and realize the automatic cleaning function of sand around the borehole.
