[0017] The present invention will now be described in detail with reference to the embodiments, but the present invention is not limited to these embodiments.

[0018] This utility model provides a geological survey drilling device with an adjustable tilt angle, such as... Figures 1 to 5 As shown, the device includes: frame; Flip plate 7 is located on one side of the frame; The drilling unit is mounted on the flip plate 7; The height adjustment unit is slidably connected to the frame and rotatably connected to the tilting plate 7, and is used to drive the tilting plate 7 to slide vertically on the frame to adjust the height of the drilling unit; Driven gear 18 is fixed on the flip plate 7 and is coaxial with the rotating shaft 5 of the flip plate 7; The driving gear 17 meshes with the driven gear 18; An angle adjustment unit is installed on the height adjustment unit and connected to the drive gear 17 to drive the drive gear 17 to rotate. When the drive gear 17 rotates, it drives the flip plate 7 to tilt and rotate in the vertical plane through the driven gear 18 to adjust the tilt angle of the drilling unit.

[0019] Specifically, the rack may include: Base 1; Two side plates 2 are arranged opposite each other, and their bottom ends are connected to the top of the base 1; The top plate 26 is connected to the top of the two side plates 2 at both ends; the height adjustment unit is slidably connected to the two side plates 2 and can slide vertically on the two side plates 2.

[0020] In this embodiment, the base 1 is equipped with multiple casters 8, which facilitates the rapid movement and position adjustment of the device within the site to adapt to different surveying needs. The base 1 can be mounted on the electric slide rail of an external positioning system to achieve high-precision positioning and ensure accurate drilling location.

[0021] Specifically, the height adjustment unit may include: The slide table 3 is slidably connected to the two side plates 2; the flip plate 7 is rotatably connected to one side of the slide table 3; the angle adjustment unit is set on the slide table 3. The first drive assembly is connected to the slide 3 and is used to drive the slide 3 to slide vertically on the two side plates 2.

[0022] In this embodiment, a vertical slide groove 11 is provided on each of the two opposite sides of the two side plates 2 of the frame; two sliders 12 are provided on each side of the slide table 3; the two sliders 12 correspond one-to-one with the two slide grooves 11, and each slider 12 can slide vertically in the corresponding slide groove 11, thereby realizing the vertical sliding of the slide table 3 between the two side plates 2.

[0023] Specifically, the flip plate 7 includes a plate body, a rotating shaft 5, and two lugs 6. One end of each lug 6 is fixedly connected to both sides of the plate body, and the other end is fixedly connected to both ends of the rotating shaft 5. The slide table 3 has an extension 4 on the side adjacent to the two side plates 2. The rotating shaft 5 of the flip plate 7 passes through the end of the extension 4, realizing a rotatable connection between the flip plate 7 and the extension 4. When the flip plate 7 rotates, its plate body, rotating shaft 5, and two lugs 6 rotate coaxially. The driven gear 18 is fixed on one of the lugs 6 and coaxial with the rotating shaft 5, and can rotate coaxially with the rotating shaft 5.

[0024] Specifically, the drilling unit may include: The drill rod 14 is located below the tilting plate 7; it remains vertical during operation. The second motor 13 is mounted on the tilting plate 7 and connected to the top of the drill rod 14, and is used to drive the drill rod 14 to drill a hole. Both the drill rod 14 and the second motor 13 can rotate with the tilting plate 7.

[0025] Specifically, the slide 3 has a through threaded hole; the first drive assembly may include: The threaded rod 10 is vertically inserted into the threaded hole and threadedly connected to the threaded hole, and its bottom end is rotatably connected to the base 1. The first motor 9 is mounted on the top plate 26 and connected to the top end of the threaded rod 10. It is used to drive the threaded rod 10 to rotate so as to drive the slide table 3 to slide vertically.

[0026] Specifically, the driving gear 17 and the driven gear 18 can be spur gears, helical gears, herringbone gears, bevel gears, etc., as long as they can mesh with each other. This embodiment uses bevel gears as an example where both the driving gear 17 and the driven gear 18 are bevel gears.

[0027] Specifically, such as Figure 4 As shown, the angle adjustment unit may include: The connecting plate 16 is fixed on the slide table 3 and has a through clearance hole 20. The key shaft 15 passes through the relief hole 20, its top end is rotatably connected to the top plate 26, and its bottom end is rotatably connected to the base 1; the drive gear 17 is coaxially sleeved on the key shaft 15, can slide vertically along the key shaft 15, and is rotatably connected to the connecting plate 16. The second drive assembly is connected to the key shaft 15 and is used to drive the key shaft 15 to rotate so as to drive the drive gear 17 to rotate.

[0028] In this embodiment, the outer surface of the key shaft 15 has multiple long strip keys parallel to its axial direction, and the inner surface of the drive gear 17 has multiple grooves. These grooves match the long strip keys one by one, allowing the drive gear 17 to be coaxially mounted on the key shaft 15 and to slide vertically along the key shaft 15. The long strip keys and grooves form a keyed connection between the key shaft 15 and the drive gear 17, achieving circumferential fixation of the key shaft 15 and the drive gear 17, enabling synchronous rotation. They also serve a guiding function, allowing the drive gear 17 to slide vertically on the key shaft 15.

[0029] In this embodiment, the connecting plate 16 is L-shaped and disposed below the slide table 3. One end of the connecting plate 16 is fixedly connected to the bottom of the slide table 3, and the other end is close to the driven gear 18. The driving gear 17 is rotatably connected to the upper surface of the end of the connecting plate 16 close to the driven gear 18. Since the connecting plate 16 is fixedly connected to the slide table 3, the relative position of the slide table 3 and the driving gear 17 on the connecting plate 16 is fixed. At the same time, since the relative position of the slide table 3 and the rotating shaft 5 of the flip plate 7 is fixed, the relative position of the slide table 3 and the driven gear 18 on the rotating shaft 5 is also fixed. Therefore, when the slide table 3 slides vertically, it will drive the connecting plate 16 and the rotating shaft 5 of the flip plate 7 to move vertically synchronously, thereby driving the driving gear 17 and the driven gear 18 to slide vertically synchronously. That is, when the slide table 3 slides vertically, the relative position between the driving gear 17 and the driven gear 18 will not change, and the two will always remain in a meshed state. Meanwhile, when the slide table 3 slides vertically, the driving gear 17, which is in a non-rotating state, can restrict the rotation of the driven gear 18. This can prevent the tilting plate 7 from tilting and rotating during the height adjustment process, thereby ensuring that the drill rod 14 is in a vertical working state.

[0030] To enhance the stability of the key shaft 15 during operation, this embodiment also provides a strip plate 19 on the top plate 26 of the frame, so that the top end of the key shaft 15 is rotatably connected to the strip plate 19, which can prevent the key shaft 15 from shaking during operation.

[0031] Specifically, such as Figure 5 As shown, the second driving component may include: The worm gear 23 is coaxially mounted on the key shaft 15; The bracket 21 is connected to the base 1 and has two opposing side walls; The worm 22 meshes with the worm wheel 23, and its two ends are rotatably connected to the two side walls of the bracket 21, with one end passing through the corresponding side wall. The handle 25 is connected to one end of the worm gear 22 that passes through the side wall, and is used to drive the worm gear 22 to rotate.

[0032] In this embodiment, the worm gear 23 is coaxially sleeved on the bottom end of the key shaft 15, and the bottom of the worm gear 23 is coaxially connected to the vertical shaft 24, which is rotatably connected to the base 1.

[0033] In use, the handle 25 drives the worm 22 to rotate, the worm 22 drives the worm wheel 23 to rotate, the worm wheel 23 drives the key shaft 15 and the vertical shaft 24 to rotate, and the key shaft 15 in turn drives the driving gear 17 and the driven gear 18 to rotate, ultimately realizing the tilting rotation of the flip plate 7 and the drill rod 14.

[0034] Specifically, the helix angle of the worm 22 is smaller than the friction angle between the worm 22 and the worm wheel 23. This makes the transmission between the worm 22 and the worm wheel 23 self-locking, which can ensure that the key shaft 15 stays stably at any angle and prevents accidental rotation caused by external forces. Thus, the tilt angle of the drill pipe 14 can be reliably locked.

[0035] The usage process of this embodiment is as follows: The first motor 9 and the second motor 13 are started. The first motor 9 drives the threaded rod 10 to rotate, which in turn drives the slide table 3 to descend. During the descent of the slide table 3, the drill rod 14 descends and contacts the drilling position via the tilting plate 7. As the tilting plate 7 continues to descend, the second motor 13 drives the drill rod 14 to rotate at high speed, performing drilling operations at the drilling position. When maintenance is required on the drill rod 14 after drilling, the handle 25 is turned to rotate the worm gear 22. The worm gear 22 drives the worm wheel 23 to rotate, which in turn drives the vertical shaft 24 and the key shaft 15 to rotate. The key shaft 15 drives the drive gear 17 to rotate, which in turn drives the driven gear 18 and the rotating shaft 5 of the tilting plate 7 to rotate. During the rotation of the rotating shaft 5, the lug 6 drives the tilting plate 7 to tilt and rotate, thereby adjusting the drill rod 14 to a horizontal position. After the drill rod 14 is in a horizontal position, the first motor 9 drives the threaded rod 10 to rotate again. The threaded rod 10 drives the slide 3 to descend again. The slide 3 drives the tilting plate 7 and the horizontal drill rod 14 to continue to descend until the drill rod 14 is adjusted to a suitable height for maintenance work.

[0036] This embodiment uses a tilting plate 7 and an angle adjustment unit. A driven gear 18 is mounted on the rotating shaft 5 of the tilting plate 7, and a driving gear 17 meshes with the driven gear 18 on the angle adjustment unit. The angle adjustment unit drives the driving gear 17 to rotate, which in turn drives the driven gear 18 to rotate. The driven gear 18 then tilts the tilting plate 7, thus adjusting the angle of the drilling unit on the tilting plate 7. This allows for horizontal placement of the drill rod 14 during maintenance by adjusting the tilt angle of the drilling unit, eliminating the need for disassembly and reassembly. This significantly reduces the workload and complexity of maintenance work, greatly improving efficiency.

Although this application discloses preferred embodiments as described above, it is not intended to limit this application.
