[0001] This application relates to the technical field of drilling, and particularly to a foundation drilling device. Background Art

[0002] The foundation refers to the soil or rock mass that supports the foundation under a building. The soil layers serving as the building foundation are divided into rock, gravel soil, sandy soil, silt, cohesive soil, and artificial fill. There are two types of foundations: natural foundation and artificial foundation. A natural foundation is a natural soil layer that does not require human reinforcement, while an artificial foundation requires human reinforcement treatment. Common methods include stone chip cushion, sand cushion, mixing lime soil backfill and ramming, etc. During the foundation construction process, drilling equipment is required for drilling, grouting, and other operations.

Detailed implementation manners

[0022] The following further elaborates on this application in conjunction with the attached Figures 1-5 drawings for a more detailed description.

[0023] The embodiment of this application discloses a ground drilling device. Refer to Figures 1-5A foundation drilling device includes a base 1, the outer wall of the base 1 is rotatably connected to a turntable 4, the outer wall of the turntable 4 is fixedly connected to a bracket 2, and the turntable 4 is driven to rotate, so that the turntable 4 drives the bracket 2 to rotate, thereby facilitating the subsequent cleaning of the soil, and the inner walls of both sides of the bracket 2 are rotatably connected to two threaded rods 3, the spiral opening angle of the two threaded rods 3 is 20 degrees, and the friction angle is greater than the spiral angle of the threaded rods 3, thereby facilitating the self-locking of the moving frame 5 on the two threaded rods 3, and the outer walls of the two threaded rods 3 are provided with a moving frame 5, and The movable frame 5 is threadedly sleeved on the two threaded rods 3, and the outer wall of the movable frame 5 is fixedly connected to the connecting frame 9, and the outer wall of the connecting frame 9 is rotatably connected to the support plate 11. By driving the two threaded rods 3 to rotate synchronously, it is convenient for the supporting plate 11 to move up and down through the movable frame 5 and the connecting frame 9, and then it is convenient for it to drive the spiral drill rod 12 to move down to drill holes. The outer wall of the connecting frame 9 away from the support plate 11 is symmetrically fixedly connected to two support plates 15, and a worm 17 is arranged between the two support plates 15, and the worm 17 is rotatably connected to the two support plates 15. The outer wall of the connecting frame 9 is rotatably connected with a worm gear 16 and fixedly connected to the support plate 11. The worm gear 16 is meshed with the worm 17. By driving the worm 17 to rotate, the worm gear 16 is driven to rotate, and then the worm gear 16 drives the support plate 11 to rotate synchronously, so that it is convenient to control the rotation and tilt of the auger rod 12, so as to facilitate the falling of the soil of the auger rod 12 and the cleaning of the soil. At the same time, the worm gear 16 and the worm 17 can achieve a self-locking effect. The bottom outer wall of the support plate 11 is provided with an auger rod 12 for drilling. The upper surface of the support plate 11 is provided with a second drive motor 10 for driving the auger rod 12. The second drive motor 10 is started by an external power supply to drive and rotate the auger rod 12, and then the support plate 11 is moved downward to facilitate drilling holes in the ground. At the same time, when cleaning it, the turntable 4 drives the bracket 2 to rotate, so that the auger rod 12 rotates to one side of the foundation hole, and then the auger rod 12 is tilted, and the auger rod 12 is driven to rotate in a certain direction to make the soil fall.

[0024] The outer wall of the support plate 11 is fixedly connected to a limiting rod 14, the outer wall of the connecting frame 9 is provided with an arc groove 13, and the limiting rod 14 is slidably connected to the arc groove 13. The limiting rod 14 and the arc groove 13 are slidably limited, so that the support plate 11 is limited when it rotates and is restored to its original position.

[0025] The outer wall of the top of the bracket 2 is rotatably connected with two sprocket discs 6, and the two sprocket discs 6 are fixedly connected with the two threaded rods 3. A chain 7 is arranged between the two sprocket discs 6, and the chain 7 is engaged with the two sprocket discs 6. By driving one of the sprocket discs 6 to rotate, the sprocket disc 6 is used as the main driving force to drive the other sprocket disc 6 to rotate through the chain 7, so as to realize the synchronous driving rotation of the two sprocket discs 6, and then drive the two threaded rods 3 to rotate synchronously through the two sprocket discs 6.

[0026] The outer wall of the top of the bracket 2 is fixedly connected with a first driving motor 8, and the output shaft of the first driving motor 8 is fixedly connected with the sprocket disc 6. The outer wall of the top of the bracket 2 is fixedly connected with a first driving motor 8, and the output shaft of the first driving motor 8 is fixedly connected with the sprocket disc 6. By turning on the external power switch to start the first driving motor 8, the output shaft of the first driving motor 8 drives one of the sprocket discs 6 to rotate.

[0027] A servo motor 19 for driving the turntable 4 to rotate is arranged on the outer wall of the bottom of the base 1. By turning on the external power switch to start the servo motor 19, it drives the turntable 4 to rotate.

[0028] A micro motor 18 for driving the worm 17 to rotate is arranged on the side outer wall of the support plate 15. The model of the micro motor 18 is preferably 0IK1A - AW3U. By turning on the external power switch to start the micro motor 18, the output shaft of the micro motor 18 drives the worm 17.

[0029] The implementation principle of a ground drilling device in an embodiment of this application is as follows: First, move this device to the position where drilling is to be carried out, align the spiral drill rod 12 with the drilling location, and then start the first drive motor 8 through an external power switch, so that the first drive motor 8 drives one of the sprocket discs 6 to rotate. Thus, the sprocket disc 6 drives the other sprocket disc 6 to rotate through the chain 7, and then the two sprocket discs 6 rotate synchronously. Then, the two sprocket discs 6 drive the two threaded rods 3 to rotate synchronously, so that the two threaded rods 3 drive the moving frame 5 to move up and down, causing the moving frame 5 to move downward. Thus, the moving frame 5 drives the support plate 11 to move downward through the connecting frame 9. At the same time, start the second drive motor 10 through an external power switch, so that its output shaft drives the spiral drill rod 12 to rotate. Then, the drill bit at the top of the spiral drill rod 12 contacts the ground to achieve drilling of the ground. When drilling to a certain extent and it is necessary to clean the soil on the spiral drill rod 12, separate the spiral drill rod 12 from the ground by moving it upward. Then, start the servo motor 19 through an external power switch, so that the servo motor 19 drives the turntable 4 to rotate, and then the spiral drill rod 12 rotates to move it away from the drilling position. Then, start the micro motor 18 through an external power switch, so that the output shaft of the micro motor 18 drives the worm 17 to rotate. Then, the worm 17 drives the worm wheel 16 to rotate, causing the worm wheel 16 to drive the support plate 11 to rotate, and the spiral drill rod 12 rotates along the trajectory of the arc-shaped groove 13, so that the spiral drill rod 12 tilts. By driving the spiral drill rod 12 to rotate in the reverse direction, the soil on the spiral drill rod 12 falls to the ground to complete the cleaning of the soil, and at the same time, it also prevents the soil from returning to the foundation hole.
