[0027] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0028] As described in the background art, the drilling device in the above patent cannot quickly disassemble and replace the drill bit and drill rod during use, and the efficiency of using only the drill bit directly to operate is not high. In addition, the device is fixed by four fixed piles at the corners, which is not only inconvenient to move, but the area near the oil field is often uneven, and it is difficult for the four corners of the device to contact the ground at the same time, making it difficult to install the device stably.

[0029] In order to solve this technical problem, the utility model provides a high-frequency drilling device, which is applied to oil field drilling.

[0030] Specifically, please refer to Figures 1-6 , the high-frequency drilling device specifically includes:

[0031] Mounting plate 1, drill rod 2, through hole 3, drill bit 4, driving and fixing mechanism 5 and moving and fixing mechanism 6. The drill rod 2 is provided in the middle of the upper part of the mounting plate 1. A through hole 3 is provided on the surface of the mounting plate 1 at a position corresponding to the drill rod 2. The lower end of the drill rod 2 is fixedly connected to the drill bit 4. A driving and fixing mechanism 5 for driving and fixing the drill rod 2 is provided above the mounting plate 1. Moving and fixing mechanisms 6 for moving and fixing the device are provided at the four bottom corners below the mounting plate 1.

[0032] The driving and fixing mechanism 5 includes a supporting slide bar 7, a top plate 8, a driving assembly and a positioning assembly. The supporting slide bar 7 is vertically fixedly connected to the top of the mounting plate 1, and the top plate 8 is fixedly connected to the top of the supporting slide bar 7.

[0033] The high-frequency drilling device provided by the present invention, through the structural design of the driving fixing mechanism 5, can quickly disassemble the drill rod 2 and the drill bit 4 by rotating the rotating sleeve 14 when in use, and when the drill rod 2 and the drill bit 4 are working, the high-frequency resonator 17 fixed on the drill bit 4 can drive the drill bit 4 to vibrate and break the rock, thereby effectively improving the working efficiency of the device.

[0034] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0035] Example 1:

[0036] Please refer to Figure 1-Figure 4 A high-frequency drilling device includes: a mounting plate 1, a drill rod 2, a through hole 3, a drill bit 4, a driving and fixing mechanism 5, and a moving and fixing mechanism 6. The drill rod 2 is provided in the upper middle part of the mounting plate 1, and a through hole 3 is opened on the surface of the mounting plate 1 at a position corresponding to the drill rod 2. The drill bit 4 is fixedly connected to the lower end of the drill rod 2. A driving and fixing mechanism 5 for driving and fixing the drill rod 2 is provided above the mounting plate 1. The four bottom corners below the mounting plate 1 are each provided with a moving and fixing mechanism 6 for moving and fixing the device.

[0037] Specifically, the driving and fixing mechanism 5 includes a supporting slide bar 7, a top plate 8, a driving assembly and a positioning assembly. The supporting slide bar 7 is vertically fixedly connected to the top of the mounting plate 1, and the top plate 8 is fixedly connected to the top of the supporting slide bar 7.

[0038] Furthermore, the driving assembly includes a hydraulic telescopic cylinder 9, a movable plate 10, a driving motor 11 and a connecting seat 12. The hydraulic telescopic cylinder 9 is fixedly connected to the top of the top plate 8, and the movable plate 10 is provided below the top plate 8. The movable plate 10 is slidingly connected to the surface of the supporting slide rod 7. The telescopic end of the hydraulic telescopic cylinder 9 passes through the top plate 8 and is fixedly connected to the movable plate 10. The driving motor 11 is fixedly connected to the middle part of the bottom of the movable plate 10, and the output end of the driving motor 11 is fixedly connected to the connecting seat 12.

[0039] It can be seen that when in use, the hydraulic telescopic cylinder 9 can be started to drive the movable plate 10 together with the drive motor 11, the connecting seat 12, the drill rod 2 and the drill bit 4 to move downward, and then the drive motor 11 can be started to drive the connecting seat 12, the drill rod 2 and the drill bit 4 to rotate.

[0040] Furthermore, the positioning assembly includes a threaded seat 13, a rotating sleeve 14, a clamping block 15 and a spring 16. The threaded seat 13 is fixedly connected to the bottom of the connecting seat 12, and the outer side of the threaded seat 13 is threadedly connected to the rotating sleeve 14. A plurality of clamping blocks 15 are movably connected to the bottom of the threaded seat 13 and located on the inner side of the rotating sleeve 14. A spring 16 is fixedly connected between each of the plurality of clamping blocks 15. The upper end of the drill rod 2 extends to the inner side of the rotating sleeve 14, and the plurality of clamping blocks 15 are tightly fitted to the surface of the drill rod 2.

[0041] It can be seen that when the drill rod 2 and the drill bit 4 need to be disassembled and replaced, the rotating sleeve 14 can be rotated to disengage the rotating sleeve 14 from the clamping block 15, and then the spring 16 between the clamping block 15 elastically pushes the clamping block 15 to no longer fit the surface of the drill rod 2, thereby completing the disassembly of the drill rod 2 and the drill bit 4. After the replaced drill rod 2 is re-inserted into the inner side of the clamping block 15 from the rotating sleeve 14, the rotating sleeve 14 is then screwed back along the threaded seat 13, and the clamping block 15 will be squeezed by the rotating sleeve 14 to re-clamp the outer side of the drill rod 2, thereby completing the installation of the drill rod 2 and the drill bit 4.

[0042] Furthermore, in order to improve the drilling efficiency of the drill bit 4, a high-frequency resonator 17 is fixedly connected to the middle part of the drill bit 4. When in use, the high-frequency resonator 17 can drive the drill bit 4 to perform high-frequency resonance, so that the drill bit 4 can break the rock more easily, effectively improving the working efficiency of the device.

[0043] Example 2:

[0044] The high-frequency drilling device provided in Example 1 is further optimized, specifically, as follows Figure 5-Figure 6 As shown, further, the movable fixing mechanism 6 includes a sleeve rod 18, a support leg 19, a movable track 20, a threaded rod 21, a hand plate 22 and a fixing assembly. The sleeve rod 18 is fixedly connected to the bottom of the mounting plate 1, the support leg 19 is slidably connected to the inner side of the sleeve rod 18, and the movable track 20 is fixedly connected to the bottom of the support leg 19. The threaded rod 21 is vertically rotatably connected to the surface of the mounting plate 1 and at a position corresponding to the support leg 19. The support leg 19 is threadedly connected to the threaded rod 21. A hand plate 22 is rotatably connected to the top of the mounting plate 1 and at a position corresponding to the threaded rod 21. The hand plate 22 is fixedly connected to the threaded rod 21.

[0045] It can be seen that when in use, the device can be quickly moved to the specified position by moving the track 20, and then the threaded rod 21 can be driven to rotate by rotating the hand plates 22 at the four corners respectively, thereby driving the support legs 19 and the moving track 20 to move downward, thereby ensuring that the four corners of the device can contact the ground at the same time, effectively improving the stability and practicality of the device.

[0046] Furthermore, the fixing assembly includes a fixing rod 23 and a screw pile 24. The outer side of the support leg 19 is fixedly connected to the fixing rod 23, and the end of the fixing rod 23 away from the support leg 19 is vertically threadedly connected to the screw pile 24. The screw pile 24 is a steel pile with a spiral shape. By rotating into the soil, it can provide very good stability, especially suitable for soft soil. The device can be quickly fixed to the ground by rotating the screw pile 24, and the screw pile 24 performs well in a vibration environment, can effectively transfer the load, reduce the impact of vibration on the equipment, and at the same time can provide strong support when the soil is soft or weak.
