Description

Technical Field

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

[0002] A drilling device for geological exploration is a specialized piece of equipment used in the field of geological exploration. It mainly uses mechanical power to drive the drill bit to drill into the ground to obtain geological samples such as rock cores and soil samples. At the same time, it can measure geological parameters such as stratum depth, lithology, and groundwater, providing basic data support for mineral resource exploration, engineering construction site surveys, and geological disaster investigations. Its core function is to realize the detection and analysis of geological structures below the Earth's surface, and it has the characteristics of adapting to different stratum conditions and accurately obtaining geological information.

[0003] The existing drilling rigs are not equipped with positioning assistance devices, which makes the drilling rigs prone to shaking when the geological conditions are uneven, thus affecting the quality of geological drilling and causing damage to the drilling rigs.

[0004] An existing patent (publication number: CN211974889U) discloses a geological exploration drilling machine with a positioning auxiliary device, including a drilling machine body. A fixed frame is fixedly connected to the bottom of the drilling machine body. Rotating blocks are rotatably connected to the front and rear sides of the top of the inner cavity of the fixed frame via rotating shafts. A connecting rod is fixedly connected between the front and rear rotating blocks. Support mechanisms are provided on the front and rear sides of one side of the connecting rod. This utility model unlocks the locking block by rotating the knob in sequence, and then rotates the rotating block to both sides. The depth of the insertion rod into the soil is adjusted by the setting of the support mechanism. This geological exploration drilling machine has the advantage of positioning assistance. It uses multiple support mechanisms to support the fixed frame, which prevents the fixed frame from shaking when the drilling machine body is working, thus improving the stability of the drilling machine body. Moreover, the support mechanism can be folded to reduce the space occupied by the geological exploration drilling machine.

[0005] To address the aforementioned problems, existing patents have provided solutions. However, most existing geological exploration drilling devices lack effective positioning and adjustment structures, making it difficult to adjust the positioning force on the drill rod according to actual drilling needs. This causes the drill rod to easily shake and deviate during drilling, affecting the accuracy of the drilling direction and reducing drilling precision. At the same time, the device's positioning function is limited, and the initial positioning accuracy is difficult to guarantee. Positioning is difficult in complex geological environments, making it inconvenient for users.

[0006] Therefore, a drilling device for geological exploration with a positioning assistance structure is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a geological exploration drilling device with a positioning auxiliary structure, which can solve the problems that most existing geological exploration drilling devices lack an effective positioning adjustment structure during use, making it difficult to adjust the positioning force of the drill rod according to the actual drilling needs. This causes the drill rod to easily shake and deviate during drilling, affecting the accuracy of the drilling direction and reducing drilling precision. At the same time, the device has a single positioning function, making it difficult to guarantee the initial positioning accuracy, and making positioning difficult in complex geological environments, which is inconvenient for users.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a drilling device for geological exploration with a positioning auxiliary structure, comprising a drilling structure, a drill rod assembly provided on the front side of the drilling structure, a positioning frame provided on the front side of the drilling structure, a fixing plate bolted to the top of the positioning frame, a threaded rod threadedly connected to the inner wall of the fixing plate, a positioning mechanism provided on the side of the threaded rod near the drill rod assembly, the surface of the positioning mechanism contacting the surface of the drill rod assembly, and a laser positioning assembly provided on the left side of the positioning frame;

[0009] The positioning mechanism includes a connecting frame, a ball bearing, and a positioning ball. The surface of the ball bearing is rotatably connected to the inner wall of the connecting frame, and the positioning ball is disposed on the inner wall of the connecting frame, with the surface of the positioning ball in contact with the surface of the ball bearing.

[0010] Preferably, a mounting bracket is bolted to the inner wall of the connecting frame, a bearing is fixedly connected to the inner wall of the mounting bracket, and the inner wall of the bearing is fixedly connected to the surface of the threaded rod.

[0011] Preferably, the inner wall of the connecting frame is provided with a rolling groove for use with the ball bearing, and the inner wall of the connecting frame is provided with an arc-shaped groove.

[0012] Preferably, a stabilizing block is bolted to the bottom of the connecting frame, and a positioning rod is bolted to the side of the stabilizing block near the fixing plate.

[0013] Preferably, the surface of the positioning rod is slidably connected to the inner wall of the fixing plate, and a rotating plate assembly is bolted to the side of the threaded rod away from the fixing plate.

[0014] Preferably, the inner wall of the fixing plate is provided with a threaded hole for use with the threaded rod, and the inner wall of the fixing plate is provided with a positioning hole for use with the positioning rod.

[0015] Preferably, a fixing frame is bolted to the front side of the drilling structure, and an installation component is inserted into the inner wall of the fixing frame.

[0016] Preferably, a support frame is bolted to the front side of the mounting assembly, and the side of the support frame near the positioning frame is bolted to the positioning frame.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application, by setting up a positioning mechanism, uses a fixed plate and a threaded rod on the top of the positioning frame. The contact pressure between the positioning mechanism and the drill pipe assembly can be flexibly adjusted by rotating the threaded rod, achieving precise positioning and stable clamping of the drill pipe assembly. This prevents the drill pipe assembly from shaking or shifting during drilling, ensuring the accuracy of the drilling direction. The ball bearings in the positioning mechanism are rotatably connected to the connecting frame, and the design of the positioning ball contacting the ball bearings can reduce friction with the surface of the drill pipe assembly while ensuring the positioning effect, avoiding damage to the drill pipe assembly, extending the service life of the drill pipe assembly, and improving the stability and reliability of drilling operations.

[0019] 2. This application, by setting up a laser positioning component, the laser positioning component set on the left side of the positioning frame can emit a laser beam to accurately calibrate the position of the drill rod assembly, providing an intuitive and accurate positioning reference for drilling operations, improving the initial positioning accuracy of drilling, reducing invalid drilling caused by positioning deviation, and facilitating the adjustment of the positioning ball's position.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-7 The present invention provides the following technical solution:

[0030] A drilling device for geological exploration with a positioning auxiliary structure includes a drilling structure 1, a drill rod assembly 3 is provided on the front side of the drilling structure 1, a positioning frame 4 is provided on the front side of the drilling structure 1, a fixing plate 5 is bolted to the top of the positioning frame 4, a threaded rod 6 is threadedly connected to the inner wall of the fixing plate 5, a positioning mechanism 2 is provided on the side of the threaded rod 6 near the drill rod assembly 3, the surface of the positioning mechanism 2 is in contact with the surface of the drill rod assembly 3, and a laser positioning assembly 7 is provided on the left side of the positioning frame 4.

[0031] The positioning mechanism 2 includes a connecting frame 201, a ball bearing 202, and a positioning ball 203. The surface of the ball bearing 202 is rotatably connected to the inner wall of the connecting frame 201, and the positioning ball 203 is disposed on the inner wall of the connecting frame 201, with the surface of the positioning ball 203 in contact with the surface of the ball bearing 202.

[0032] In this embodiment: By setting a positioning mechanism 2, during use, a fixed plate 5 and a threaded rod 6 are set on the top of the positioning frame 4. The contact pressure between the positioning mechanism 2 and the drill rod assembly 3 can be flexibly adjusted by rotating the threaded rod 6, so as to achieve precise positioning and stable clamping of the drill rod assembly 3, prevent the drill rod assembly 3 from shaking or deviating during drilling, and ensure the accuracy of the drilling direction. The ball bearing 202 in the positioning mechanism 2 is rotatably connected to the connecting frame 201, and the design of the positioning ball 203 contacting the ball bearing 202 can reduce friction with the surface of the drill rod assembly 3 while ensuring the positioning effect, avoid damage to the drill rod assembly 3, extend the service life of the drill rod assembly 3, and improve the stability and reliability of drilling operations. By setting a laser positioning component 7, which is set on the left side of the positioning frame 4, the laser positioning component 7 can emit a laser beam to accurately calibrate the position of the drill rod assembly 3, providing an intuitive and accurate positioning reference for drilling operations, improving the initial positioning accuracy of drilling, reducing invalid drilling caused by positioning deviation, and facilitating the adjustment of the positioning position of the positioning ball 203.

[0033] Specifically, such as Figure 3 As shown, a mounting bracket 8 is bolted to the inner wall of the connecting bracket 201, and a bearing 9 is fixedly connected to the inner wall of the mounting bracket 8. The inner wall of the bearing 9 is fixedly connected to the surface of the threaded rod 6.

[0034] Specifically, such as Figure 5 As shown, the inner wall of the connecting frame 201 is provided with a rolling groove 10 that works with the ball bearing 202, and the inner wall of the connecting frame 201 is provided with an arc-shaped groove 11.

[0035] Specifically, such as Figure 3 As shown, a stabilizing block 12 is bolted to the bottom of the connecting frame 201, and a positioning rod 13 is bolted to the side of the stabilizing block 12 near the fixing plate 5.

[0036] In this embodiment: by setting the mounting bracket 8 and bearing 9, the bearing 9 is fixed to the threaded rod 6 during use, which facilitates the subsequent rotation of the threaded rod 6 on the inner wall of the fixing plate 5. When the threaded rod 6 rotates, it will drive the connecting bracket 201 and the positioning ball 203 to move closer to the drill rod assembly 3, which facilitates the positioning of the drill rod assembly 3. The matching setting of the rolling groove 10 and the ball 202 provides a stable rolling track for the ball 202, so that the positioning mechanism 2 can rotate flexibly when it comes into contact with the drill rod assembly 3, further reducing friction. The setting of the arc groove 11 optimizes the movement space of the positioning ball 203 and improves the reliability of positioning. The combination of the stabilizing block 12 and the positioning rod 13 enhances the stability of the connecting bracket 201, prevents it from shifting during the adjustment process, and ensures the accuracy of positioning the drill rod assembly 3.

[0037] Specifically, such as Figure 3 As shown, the surface of the positioning rod 13 is slidably connected to the inner wall of the fixing plate 5, and the rotating plate assembly 14 is bolted to the side of the threaded rod 6 away from the fixing plate 5.

[0038] Specifically, such as Figure 6 As shown, the inner wall of the fixing plate 5 is provided with a threaded hole 15 for use with the threaded rod 6, and the inner wall of the fixing plate 5 is provided with a positioning hole 16 for use with the positioning rod 13.

[0039] In this embodiment: by setting the rotating plate assembly 14, the position of the rotating plate assembly 14 and the threaded rod 6 is fixed during use, which facilitates the subsequent rotation of the threaded rod 6 on the inner wall of the fixed plate 5 by the rotating plate assembly 14. The positioning rod 13 is slidably connected to the fixed plate 5, which facilitates the stability of the positioning ball 203 during positioning and avoids the shaking of the connecting frame 201 during use. The threaded hole 15 opened in the inner wall of the fixed plate 5 facilitates the rotation of the threaded rod 6 on the inner wall of the fixed plate 5 through the threaded hole 15. The positioning hole 16 opened in the inner wall of the fixed plate 5 facilitates the movement of the positioning rod 13 on the inner wall of the fixed plate 5 through the positioning hole 16.

[0040] Specifically, such as Figure 7 As shown, a fixing frame 17 is bolted to the front side of the drilling structure 1, and an installation component 18 is inserted into the inner wall of the fixing frame 17.

[0041] Specifically, such as Figure 2 , Figure 7 As shown, a support frame 19 is bolted to the front side of the mounting assembly 18, and the side of the support frame 19 closest to the positioning frame 4 is bolted to the positioning frame 4.

[0042] In this embodiment: the fixing frame 17 on the front side of the drilling structure 1 is plugged into the mounting component 18, providing a stable and reliable foundation for the installation of the positioning frame 4. The support frame 19 fixes the position of the positioning frame 4 and the mounting component 18, enhancing the structural strength and stability of the positioning frame 4, enabling the positioning frame 4 to better support the positioning mechanism 2 and the laser positioning component 7, ensuring the stable operation of the entire positioning auxiliary structure, and providing reliable support for the accurate positioning of the drill rod assembly 3.

[0043] Working Principle: During the use of drilling structure 1, a positioning mechanism 2 is set up. During use, a fixed plate 5 and a threaded rod 6 are set on the top of the positioning frame 4. The contact pressure between the positioning mechanism 2 and the drill rod assembly 3 can be flexibly adjusted by rotating the threaded rod 6, so as to achieve precise positioning and stable clamping of the drill rod assembly 3, preventing the drill rod assembly 3 from shaking or deviating during drilling, and ensuring the accuracy of the drilling direction. The ball bearing 202 in the positioning mechanism 2 is rotatably connected to the connecting frame 201, and the design of the positioning ball 203 contacting the ball bearing 202 can reduce friction with the surface of the drill rod assembly 3 while ensuring the positioning effect, avoiding damage to the drill rod assembly 3, extending the service life of the drill rod assembly 3, and improving the stability and reliability of drilling operations. By setting up a laser positioning component 7, which is set on the left side of the positioning frame 4, a laser beam can be emitted to accurately calibrate the position of the drill rod assembly 3, providing an intuitive and accurate positioning reference for drilling operations, improving the initial positioning accuracy of drilling, reducing invalid drilling caused by positioning deviation, and facilitating the adjustment of the positioning position of the positioning ball 203.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
