Description

Technical Field

[0001] This utility model relates to the field of geological exploration machinery and equipment technology, and in particular to a geological exploration drilling device. Background Technology

[0002] Geological exploration drilling equipment can directly drill into the ground to obtain samples of rocks, soil, and minerals, and to understand the underground lithology, structure, texture, hydrogeological conditions, etc., providing accurate data support for geological exploration. Therefore, a geological exploration drilling equipment is needed.

[0003] A search revealed a Chinese patent publication number: CN218862545U, which discloses a geological exploration drilling device, including a support base and a spiral rod threaded into the inside of both sides of the support base. The top of the support base is respectively fixedly fitted with a first sleeve and a second sleeve. The top ends of the first sleeve and the second sleeve are jointly fixedly fitted with a fixing plate, and the outer sides of the first sleeve and the second sleeve are movably fitted with a fixing frame. A motor is fixedly installed inside the fixing frame, and a transmission mechanism is engaged on the outer side of the bottom end of the motor.

[0004] The aforementioned utility model, through the coordinated use of a first limiting plate, a second limiting plate, a slewing bearing, a first bolt, and a limiting sleeve, enables the device to limit and support the drill rod through the limiting sleeve. When the drill rod contacts the limiting sleeve, the slewing bearing allows the drill rod and the limiting sleeve to rotate synchronously, thereby ensuring that the limiting sleeve supports the drill rod without affecting its normal rotation and preventing the drill rod from shifting during rotation. However, in actual use, the aforementioned device lacks a buffer design, which can easily lead to mechanical fatigue and affect its service life during prolonged operation. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a geological exploration drilling device, which aims to improve the problem that the previous technology lacked a buffer design and was prone to mechanical fatigue during long-term operation, thus affecting its service life.

[0040] Specifically, a tapered column is provided on the lower surface of the base box 1 to facilitate fixing the base box 1 to the ground. The base box 1 provides fixed support for the support plate 2, which in turn provides fixed support for the fixing plate 3. The fixing plate 3 provides fixed support for the first hydraulic cylinder 4. The first hydraulic cylinder 4 drives the sliding plate 5, which in turn drives the fixing cylinder 6 to slide on the outer wall of the support column 7. The base box 1 provides fixed support for the support column 7, which in turn provides auxiliary support for the fixing plate 3. At the same time, the sliding plate 5 drives the sliding piece 9 to slide on the outer wall of the support plate 2. The support plates 2 on both sides of the upper surface of the base box 1 provide auxiliary limiting for the sliding piece 9. As the fixing cylinder 6 moves, it compresses the spring 8, which absorbs and disperses vibration and impact. The sliding plate 5 provides fixed support for the motor 1001, which drives the drill rod 1002, which in turn drives the drill bit 1003 to perform drilling.

[0041] Reference Figure 4A second hydraulic cylinder 11 is fixedly connected inside the base box 1, and a first movable plate 12 is fixedly connected to the output end of the second hydraulic cylinder 11. A first movable shaft 13 is fixedly connected to the outer wall of the first movable plate 12, and a first connecting piece 14 is rotatably connected to the outer wall of the first movable shaft 13. A rotating shaft 15 is rotatably connected inside the first connecting piece 14, and a limit rod 16 is rotatably connected inside the rotating shaft 15. The outer wall of the limit rod 16 is fixedly connected inside the base box 1. A second connecting piece 17 is rotatably connected inside the rotating shaft 15, and a second movable shaft 21 is rotatably connected inside the second connecting piece 17. A second movable plate 18 is fixedly connected to the outer wall of the second movable shaft 21.

[0042] Specifically, the base box 1 provides fixed support for the second hydraulic cylinder 11. The second hydraulic cylinder 11 drives the first moving plate 12, which in turn drives the first moving shaft 13 to move. The first moving shaft 13 drives the first connecting piece 14, which in turn drives the rotating shaft 15 to rotate on the outer wall of the limiting rod 16. The base box 1 provides fixed support for the limiting rod 16, which in turn provides auxiliary support and limits for the rotating shaft 15. At the same time, the rotating shaft 15 drives the second connecting piece 17, which in turn drives the second moving shaft 21 to move. The second moving shaft 21 drives the second moving plate 18 to move. The first moving shaft 13 connects the first moving plate 12 and the first connecting piece 14, and the second moving shaft 21 connects the second moving plate 18 and the second connecting piece 17.

[0043] Reference Figure 1 and Figure 4 The second movable plate 18 and the first movable plate 12 are both slidably connected to the interior of the fixed column 19, and both ends of the fixed column 19 are fixedly connected to the interior of the base box 1; the outer walls of the second movable plate 18 and the first movable plate 12 are both fixedly connected to the clamping block 20, and the outer wall of the clamping block 20 is slidably connected to the outer wall of the drill rod 1002.

[0044] Specifically, the first movable plate 12 and the second movable plate 18 slide on the outer wall of the fixed column 19, and the base box 1 provides fixed support for the fixed column 19. In turn, the fixed column 19 provides auxiliary support and limit for the first movable plate 12 and the second movable plate 18, thereby driving the clamping block 20 to position and limit the drill rod 1002, thus preventing it from shaking or deviating during drilling.

[0045] Working principle: When the device is needed, the base box 1 is fixed at the location to be surveyed, and the second hydraulic cylinder 11 inside the base box 1 is activated. The second hydraulic cylinder 11 drives the first moving plate 12, which in turn drives the first moving shaft 13 to move. The first moving shaft 13 drives the first connecting piece 14, which in turn drives the rotating shaft 15 to rotate on the outer wall of the limiting rod 16. At the same time, the rotating shaft 15 drives the second connecting piece 17, which in turn drives the second moving shaft 21 to move. The movement of the second moving shaft 21 drives the second moving plate 18 to move. The first moving plate 12 and the second moving plate 18 slide on the outer wall of the fixed column 19, thereby driving the clamping block 20 to position and limit the drill rod 1002, preventing it from shaking or shifting during drilling.

[0046] The first hydraulic cylinder 4 inside the fixed plate 3 is activated, which drives the sliding plate 5 and then the fixed cylinder 6 to slide on the outer wall of the support column 7. At the same time, the sliding plate 5 drives the sliding piece 9 to slide on the outer wall of the support plate 2. As the fixed cylinder 6 moves, it compresses the spring 8. Simultaneously, the motor 1001 inside the sliding plate 5 is activated, which drives the drill rod 1002 and then the drill bit 1003 to drill. This device can not only absorb and disperse the vibration and impact generated during drilling, reducing their damage to the drilling equipment, but also firmly clamp the drill rod 1002 to prevent it from shaking or shifting during drilling. It can also adapt to drill rods 1002 of different sizes, improving the versatility of the equipment.
