Abstract
Description
Technical Field
[0001] This utility model relates to the field of borehole sampling machine technology, and more specifically, it relates to a borehole sampling machine for highway quality inspection. Background Technology
[0002] In existing technologies, borehole sampling machines used for highway quality testing often require sampling at multiple different locations along the highway to comprehensively analyze and evaluate its quality. However, existing equipment typically has a simple and inflexible design for fixing the position of the borehole sampling machine, making it impossible to quickly adjust the fixed position. This results in a significant amount of time and effort being spent moving the equipment and manually adjusting its position during multi-point sampling. This operation is not only time-consuming and labor-intensive, but may also affect the sampling accuracy due to inaccurate positioning, thereby reducing the reliability and scientific validity of highway testing data.
[0003] In addition, due to the limitations of existing borehole sampling machines in terms of fixing methods, the equipment may experience insufficient stability during operation. For example, in complex road surfaces or uneven highway areas, the equipment is prone to shaking or shifting, which further affects the stability of the drilling operation and the accuracy of the sampling results.

[0015] (III) Beneficial Effects
[0016] Compared with the prior art, this utility model provides a drilling and sampling machine for highway quality inspection, which has the following beneficial effects:
[0017] 1. The fixing mechanism, through the coordinated use of adjusting components and connectors, achieves a stable connection between the intermediate frame and the fixed base, ensuring the stability of the equipment during operation. The intermediate frame is connected to the follower rod through a fixed sleeve. The follower rod can not only achieve angle adjustment within a certain range through rotation, but also further enhance the flexibility of the equipment through the sliding engagement of the transverse groove and the transverse rod. During the fixing process, the transverse rod, through its engagement with the transverse hole on the inner wall of the fixed sleeve, can firmly hold the follower rod in the designated position, thereby ensuring the precise positioning of the equipment during operation. This structural design enables the equipment to not only maintain stability during use, but also adapt to the sampling needs of complex road surfaces, significantly improving the reliability and stability of the sampling process.
[0018] 2. The adjustment mechanism achieves efficient adjustment of the sampling tube position through the combined use of guide components, lifting mechanism and motor drive. With the installation of guide rod, the lifting component can slide along a predetermined trajectory on the fixed base, while the lifting motor drives the threaded connection of the lead screw, enabling the lifting frame to move up and down flexibly, ensuring that the sampling tube can be accurately aligned with the target position. In addition, the drive motor is connected to the drive shaft through the transmission device, which in turn drives the rotation and movement of the sampling tube, thereby quickly adjusting the sampling position in complex environments.
[0019] 3. The positioning mechanism, through the design of the intermediate rod, rotating sleeve, and expansion spring assembly, achieves the quick locking and unlocking functions of the equipment. The intermediate rod engages with the hole in the follower rod via a sliding mechanism. During operation, the user can press the intermediate rod to allow the top ball to enter the release ring, thereby releasing the fixed state between the transverse rod and the transverse hole, allowing the follower rod to be adjusted in angle. Once adjusted, pulling the intermediate rod causes the top ball to engage in the fixing groove, at which point the transverse rod will be re-pressed into the transverse hole, thus completing the fixation of the follower rod. This positioning mechanism design is simple and efficient, enabling quick angle adjustment of the equipment while ensuring the stability of the equipment after fixation, effectively improving the flexibility and reliability of operation.

[0029] Please see Figure 1-5 A drilling and sampling machine for highway quality inspection includes a fixed base 1, on which a fixing mechanism is provided. The fixing mechanism includes an adjusting mechanism, an intermediate frame 2, an adjusting bracket 3, a fixed sleeve 4, a follower rod 5, a transverse rod 6, and a positioning mechanism. The adjusting mechanism is connected to the fixed base 1 and the intermediate frame 2. The adjusting bracket 3 is fitted onto the intermediate frame 2. The fixed sleeve 4 is fixedly installed on the intermediate frame 2. The follower rod 5 is rotatably connected inside the fixed sleeve 4 and fixedly installed on the adjusting bracket 3. A transverse groove 7 is formed on the side wall of the follower rod 5, and the transverse rod 6 is slidably connected inside the transverse groove 7. A transverse hole 8 is formed on the inner wall of the fixed sleeve 4, and the transverse rod 6 abuts against the transverse hole 8. The positioning mechanism is installed on the fixed sleeve 4 and includes an intermediate rod 9. An internal hole 10 is formed inside the follower rod 5, and the intermediate rod 9 is slidably connected to the internal hole 10. Inside the hole 10, a rotating sleeve 11 is coaxially provided on the follower rod 5. The rotating sleeve 11 is rotatably connected to the fixed sleeve 4. Multiple release slots 12 are equidistantly provided on the intermediate rod 9. Multiple expansion springs 13 are provided inside the rotating sleeve 11. Each of the multiple expansion springs 13 is provided with a top ball 14. Fixed slots 15 and release rings 16 are provided on the side wall of the intermediate rod 9. The adjustment mechanism includes a guide rod 17, a lifting frame 18, a lifting motor 19 and a lead screw 20. The guide rod 17 is installed on the fixed seat 1. The extended end of the lifting motor 19 is connected to the lead screw 20. The lead screw 20 is threadedly connected to the lifting frame 18. A drive motor 21 is fixedly provided on the adjustment frame 3. A transmission shaft 22 is rotatably provided on the adjustment frame 3. Belts 23 are respectively meshed on the extended ends of the transmission shaft 22 and the drive motor 21. A sampling tube 24 is provided on the transmission shaft 22.
[0030] In this embodiment, when sampling, the intermediate frame 2 and the adjusting frame 3 are first moved to their respective positions, and then the sampling tube 24 is adjusted to the corresponding position before the intermediate frame 2 and the adjusting frame 3 are fixed. Then, the lifting frame 18 is driven to slide downward by the lead screw 20, so that the sampling tube 24 can take a sample, thereby completing the sampling process.
[0031] More specifically, when rotation is required, press down on the middle rod 9, causing the top ball 14 to engage in the release ring 16, and then the release groove 12 to be positioned in the position of the transverse rod 6. At this time, the transverse rod 6 and the transverse hole 8 are not in a fixed state, so rotation is possible. When fixation is required, pull the middle rod 9 upward, causing the top ball 14 to engage in the fixation groove 15. At this time, the transverse rod 6 abuts against the side wall of the middle rod 9, and then the transverse rod 6 is fixedly abutted against the transverse hole 8, thus completing the fixation process.
[0032] In summary, during the use or operation of the overall equipment: When sampling, firstly, the intermediate frame 2 and the adjusting frame 3 are moved to their respective positions. Then, the sampling tube 24 is adjusted to the corresponding position, and the intermediate frame 2 and the adjusting frame 3 are fixed. Then, the lifting frame 18 is driven downward by the lead screw 20, so that the sampling tube 24 can take a sample, thus completing the sampling process. When rotation is required, the intermediate rod 9 is pressed down, so that the top ball 14 is locked in the release ring 16, and the release groove 12 is in the position of the transverse rod 6. At this time, the transverse rod 6 and the transverse hole 8 are not in a fixed state, so they can be rotated. When fixing is required, the intermediate rod 9 is pulled upward, so that the top ball 14 is locked in the fixing groove 15. At this time, the transverse rod 6 is pressed against the side wall of the intermediate rod 9, and then the transverse rod 6 is fixedly abutted in the transverse hole 8, thus completing the fixing process.
