Description

Technical Field

[0001] This utility model relates to the field of geological exploration technology, specifically to a sampling drill rod for a geological exploration anchor drilling rig. Background Technology

[0002] Anchor bolt drilling rigs, also known as anchoring drills in some regions, are drilling tools used in anchor bolt support work in coal mine roadways. They offer significant advantages in improving support effectiveness, reducing support costs, accelerating roadway construction, minimizing auxiliary transportation, alleviating labor intensity, and increasing roadway cross-sectional utilization. Anchor bolt drilling rigs are key equipment in anchor bolt support, affecting the quality of the support—the accuracy of the anchor hole's orientation, depth, and diameter, as well as the quality of the anchor bolt installation—and also impacting operator safety, labor intensity, and working conditions.

[0003] However, the length of the drill rod in existing anchor drilling rigs is generally fixed and cannot be adjusted according to the actual drilling depth, thus reducing the adaptability of the device. Some devices that can adjust the length of the drill rod are more complicated to operate and cannot guarantee the stability of the adjustment process. Utility Model Content

[0039] This utility model provides a technical solution:

[0040] Please see Figures 1-3 A sampling drill rod for a geological exploration anchor drilling rig includes a mounting flange 1 and multiple axially arranged connecting holes 2 on it. A sampling mechanism is provided at the lower end of the mounting flange 1.

[0041] The sampling mechanism includes a housing 4 located at the lower end of the mounting flange 1, a fixed pipe 7 at the lower end of the housing 4, a movable pipe 5 sleeved on the outer wall of the fixed pipe 7, and a drill bit 6 at the end of the movable pipe 5.

[0042] Furthermore, the outer wall of the fixed tube 7 is provided with multiple circumferentially arranged strip grooves 8, and the inner wall of the moving tube 5 is provided with multiple sliders 9. The multiple sliders 9 are located in the multiple strip grooves 8 and are slidably connected to them. By moving the multiple sliders 9 in the multiple strip grooves 8, the moving tube 5 is driven to move on the outer wall of the fixed tube 7, thereby changing the overall length of the drill rod. This provides certain convenience for people to conduct geological exploration and sampling at different depths, while improving the overall adaptability of the device.

[0043] Furthermore, threaded rods 10 are rotatably connected to multiple strip grooves 8 and box 4, and the multiple threaded rods 10 pass through multiple sliders 9 and are threadedly connected to them.

[0044] Furthermore, a rotating shaft 12 is rotatably connected to the top of the housing 4, and a drive wheel 13 is provided on the outer wall of the rotating shaft 12.

[0045] Furthermore, each of the multiple threaded rods 10 has a driven wheel 14 on its outer wall, and each of the multiple driven wheels 14 meshes with the driving wheel 13.

[0046] Furthermore, a transmission rod 11 is rotatably connected through one side of the housing 4. Both the outer wall of the transmission rod 11 and the end of the rotating shaft 12 are provided with bevel gears 15, and the two bevel gears 15 mesh with each other.

[0047] Furthermore, a fixed frame 16 is provided on the outer wall of the housing 4, and a power motor 3 is provided inside the fixed frame 16. The end of the transmission rod 11 is connected to the end of the output shaft of the power motor 3. By utilizing the meshing of the driving wheel 13 with multiple driven wheels 14 and the meshing of two bevel gears 15, the synchronous rotation of multiple threaded rods 10 can be achieved by starting the power motor 3, thereby improving the linkage of the device and ensuring the stability of the movement of the moving tube 5.

[0048] In practical use, the working principle of this utility model is as follows:

[0049] By installing the flange 1 and multiple connecting holes 2, this device is mounted on the drilling rig (since this part is prior art, its related structure is not described in detail in this figure). When the length of the drill rod needs to be adjusted, the power motor 3 is started, which drives the transmission rod 11 to rotate. The meshing of the bevel gear 15 between the transmission rod 11 and the rotating shaft 12 causes the rotating shaft 12 to rotate, thereby causing the driving wheel 13 on the outer wall of the rotating shaft 12 to rotate. The meshing of the driving wheel 13 with multiple driven wheels 14 causes the multiple driven wheels 14 to rotate, driving multiple threaded rods 10 to rotate. The threaded connection between the threaded rod 10 and the slider 9, and the sliding connection between the slider 9 and the strip groove 8, allows the multiple sliders 9 to move in the multiple strip grooves 8 respectively, thereby driving the moving tube 5 to move on the outer wall of the fixed tube 7, thus changing the overall length of the drill rod. This provides convenience for geological exploration and sampling at different depths, while improving the overall adaptability of the device.

[0050] In summary, a sampling drill rod for a geological exploration anchor drilling rig, by improving and optimizing its working principle, solves the problem in existing technologies where the drill rod length cannot be adjusted according to the actual exploration and sampling depth, thus reducing the adaptability of the device.

[0051] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
