Description

Technical Field

[0001] This utility model relates to the field of rock and soil drilling technology, and in particular to a rock and soil engineering drilling verticality calibration guide device. Background Technology

[0002] Geotechnical drilling refers to the technical means of drilling downwards into the ground to form columnar holes using specialized drilling equipment during the investigation, design, and construction of geotechnical engineering projects. This allows for the understanding of the geological structure, soil and rock types, geological formations, and groundwater conditions, providing basic geological data for project site selection and design.

[0003] As the scale and complexity of modern engineering construction continue to increase, traditional geological exploration methods that rely on surface observation and experience-based inference can no longer meet the engineering requirements for the accuracy and depth of underground rock and soil information. At this time, a geotechnical engineering borehole device is needed to more accurately understand the geological structure.

[0004] Currently, commercially available geotechnical drilling equipment mainly consists of a drill bit, a transmission rod, a driver, and a mud pump. During use, the driver drives the drill bit to rotate via the transmission rod, enabling it to excavate through the soil and rock layers, thus completing the drilling work. During this process, the mud pump circulates the mud inside the borehole. However, during use, the drill bit can deviate during excavation, causing borehole deviation. To solve this problem, existing technology adds a guide device to the device to improve the verticality of the borehole. However, in actual use, due to varying ground flatness, this device is not convenient for use on surfaces with different inclines, reducing its practicality and failing to meet user needs.

A driving assembly is disposed on the front side of the hollow plate.

[0009] As a further description of the above technical solution:

[0010] The control component includes a fixed block, which is fixed to the inner front side of the base. A rotating rod is slidably connected to the inner side of the fixed block. A driving bevel gear is fixedly connected to the left and right sides of the outer wall of the rotating rod. The left end of the rotating rod passes through the base. A driven bevel gear is fixedly connected to the front end of each of the two bidirectional threaded rods.

[0011] As a further description of the above technical solution:

[0012] The drive assembly includes a screw, which is rotatably connected to the front left wall of the hollow plate. A second knob is fixedly connected to the left end of the screw, and a rack is threaded through the hollow plate at the right end of the screw. The rack is engaged with a toothed ring.

[0013] As a further description of the above technical solution:

[0032] 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.

[0033] Reference Figure 2 , Figure 3 and Figure 4This utility model provides an embodiment of a drilling verticality calibration guide device for geotechnical engineering, comprising a base 1. Two bidirectional threaded rods 3 are rotatably connected to the left and right sides of the interior of the base 1. Slider 4s are threadedly connected to the left and right sides of the outer walls of the two bidirectional threaded rods 3. When the bidirectional threaded rods 3 rotate, the sliders 4 can move accordingly. Connecting rods 5 are rotatably connected to the bottom of each slider 4. Fixing plates 6 are fixedly connected to the left and right sides of the interior of the base 1. Support plates 7 are slidably connected to adjacent sides of the two fixing plates 6. Connecting seats 8 are fixedly connected to the front and rear ends of the tops of the two support plates 7. The tops of the two connecting seats 8 are rotatably connected to the corresponding connecting rods 5. When the sliders 4 move, the connecting rods 5 can push the connecting seats 8 to move. Support legs 9 are fixedly connected to the front and rear ends of the bottom. The support plate 7 will drive the support legs 9 to move. Control components are provided on the front inside of the two bases 1. A guide mechanism 2 is provided on the upper side of the base 1. The guide mechanism 2 is used to provide guidance for drilling work. The control components include a fixing block 10, which is fixed to the front inside of the base 1. A rotating rod 11 is slidably connected to the inner side of the fixing block 10. A driving bevel gear 12 is fixedly connected to the left and right sides of the outer wall of the rotating rod 11. The rotating rod 11 will drive the driving bevel gear 12 to rotate. The left end of the rotating rod 11 passes through the base 1. A driven bevel gear 13 is fixedly connected to the front end of the two bidirectional threaded rods 3. When the driven bevel gear 13 meshes with the driving bevel gear 12, it will drive the driven bevel gear 13 to rotate.

[0034] Specifically, when used on a sloped surface, rotating the rotating rod 11 drives the active bevel gear 12 to rotate. When the rotating rod 11 is pulled or pushed, the active bevel gear 12 engages with the driven bevel gear 13 on the left or right side respectively, thereby adjusting the left or right support leg 9 individually. Once the driven bevel gear 13 successfully engages with the active bevel gear 12, the driven bevel gear 13 rotates along with the active bevel gear 12, thereby driving the bidirectional threaded rod 3 to rotate as well. The rotation of the bidirectional threaded rod 3 drives the slider 4 to move. During the movement of the slider 4, the connecting rod 5 enables the connecting seat 8 to move accordingly. The movement of the connecting seat 8 is transmitted to the support leg 9 through the support plate 7, thereby enabling the support leg 9 to move downwards, thus adjusting the support legs 9 on both sides separately. This ensures that the base 1 always remains horizontal, maintaining the verticality of the drilling direction, improving the practicality of the device and meeting the user's needs.

[0035] Reference Figure 1 , Figure 5 and Figure 6The guide mechanism 2 includes a hollow plate 201, which is disposed on the upper side of the base 1. A toothed ring 202 is rotatably connected to the bottom inner side of the hollow plate 201. Curved grooves 203 are formed around the top of the toothed ring 202. Insertion posts 204 are slidably connected to the inner side of the multiple curved grooves 203. The toothed ring 202 can drive the insertion posts 204 to move through the curved grooves 203. Connecting blocks 205 are rotatably connected to the top of the multiple insertion posts 204. Fixing hoops 206 are fixedly connected to one side of the multiple connecting blocks 205. The connecting blocks 205 will drive the fixing hoops 206 to move. Multiple rollers 207 are equidistantly rotatably connected to one side of the multiple fixing hoops 206. The rollers 207 enable the drill rod to rotate. The hollow plate 201 is fixedly connected to the left and right sides. A guide block 209 is fixedly connected to the base 1. Guide columns 208 are fixedly connected to the top left and right sides of the base 1. The top ends of the two guide columns 208 pass through the corresponding guide blocks 209. Through the interaction between the guide blocks 209 and the guide columns 208, the drilling work can be guided. A drive assembly is provided on the front side of the hollow plate 201. The drive assembly includes a screw 210. The screw 210 is rotatably connected to the front side of the left wall of the hollow plate 201. A second knob 212 is fixedly connected to the left end of the screw 210. The second knob 212 makes it convenient for the operator to rotate the screw 210. The right end of the screw 210 passes through the hollow plate 201 and is threadedly connected to a rack 211. The rack 211 is meshed with a toothed ring 202. When the rack 211 moves, the toothed ring 202 will rotate accordingly.

[0036] Specifically, when using this device, if guidance for drilling is required, the drill rod is placed in the inner area of ​​the hollow plate 201, and the screw 210 is rotated. As the screw 210 rotates, it drives the rack 211 to move. Since the gear ring 202 meshes with the rack 211, when the rack 211 moves under the drive of the screw 210, the gear ring 202 will also rotate and push the insertion post 204 to move through the curved groove 203. The insertion post 204, through its connection with the connecting block 205, can further drive the fixing hoop 206 to move. At this time, multiple fixing hoops 206 will move synchronously towards the center position, thereby achieving a firm fixation of the drill rod. At the same time, the cooperation between the guide block 209 and the guide post 208 provides support and guidance for drilling operations, improving the convenience of the device.

[0037] Reference Figure 1 , Figure 2 and Figure 4 The top left and right ends and front and back sides of the base 1 are provided with sliding grooves 16. The tops of multiple sliders 4 are slidably connected to the corresponding sliding grooves 16. The sliding grooves 16 can provide a limit for the movement of the sliders 4. The left end of the rotating rod 11 is fixedly connected to the first knob 14. The top front side of the base 1 is fixedly connected to the level 15.

[0038] Specifically, the movement of the slider 4 is limited by the slide groove 16, so that the slider 4 can move along with the bidirectional threaded rod 3 when it rotates. The operator can easily rotate the rotating rod 11 using the first knob 14, and the level 15 can conveniently provide the operator with level detection.

[0039] Reference Figure 5 The hollow plate 201 has slide rails 213 fixedly connected to the inner four sides. The inner sides of the multiple slide rails 213 are slidably connected to the corresponding connecting blocks 205. The slide rails 213 can provide support for the connecting blocks 205. A limit groove 214 is opened at the bottom front side of the hollow plate 201. The bottom of the rack 211 is slidably connected to the limit groove 214.

[0040] Specifically, the slide rail 213 can support and guide the movement of the connecting block 205, and limit the movement of the rack 211 through the limiting groove 214, so that the rack 211 can move along with the screw 210 when it rotates.

[0041] Working principle: When used on a sloped surface, the rotating rod 11 drives the active bevel gear 12 to rotate. By pulling or pushing the rotating rod 11, the active bevel gear 12 can mesh with the driven bevel gear 13 on the left or right side, allowing for individual adjustment of the left or right support leg 9. When the driven bevel gear 13 meshes with the active bevel gear 12, the driven bevel gear 13 drives the bidirectional threaded rod 3 to rotate, thereby driving the slider 4 to move. When the slider 4 moves, it can push the connecting seat 8 to move through the connecting rod 5. The connecting seat 8 then drives the support leg 9 to move downward through the support plate 7. By adjusting the two support legs 9 separately, the base 1 is kept in a horizontal state, ensuring that the drilling direction remains vertical.

[0042] Furthermore, when using this device, if guidance for drilling is required, the drill rod is placed inside the hollow plate 201, and the screw 210 is rotated. When the screw 210 rotates, it will drive the rack 211 to move. Since the toothed ring 202 meshes with the rack 211, when the rack 211 moves, the toothed ring 202 will rotate accordingly, and can push the plug-in post 204 to move through the curved groove 203. The plug-in post 204 can drive the fixing hoop 206 to move through the connecting block 205. Multiple fixing hoops 206 will move towards the middle at the same time, thereby fixing the drill rod. And through the sliding of the guide block 209 and the guide post 208, it can provide support for the drilling work.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
