[0019] Please refer to Figures 1-3 As shown, a positioning and adjusting device for an oil drilling rig frame includes a base 1. Four groups of support frames 2 are symmetrically installed on the base 1. Two groups of first guide plates 3 and two groups of second guide plates 4 are respectively installed on the four groups of support frames 2. A first chute 5 is formed in the first guide plate 3. A first slider 6 is assembled in the first chute 5. A first limiting groove 7 is formed in the first slider 6. A second chute 8 is formed in the second guide plate 4. A second slider 9 is assembled in the second chute 8. A second limiting groove 10 is formed in the second slider 9. A first lead screw 11 penetrates through the side wall of one of the first guide plates 3. The first lead screw 11 is slidably matched with the side wall of the first guide plate 3 through threads. The other side of the first lead screw 11 is rotatably connected to the first slider 6. A first knob 12 is installed on the first lead screw 11. A second lead screw 13 penetrates through the side wall of one of the second guide plates 4. The second lead screw 13 is slidably matched with the side wall of the second guide plate 4 through threads. The other side of the second lead screw 13 is rotatably connected to the second slider 9. A second knob 14 is installed on the second lead screw 13. A first moving rod 15 is slidably assembled in the first limiting groove 7 of the first slider 6. A second moving rod 16 is slidably assembled in the second limiting groove 10 of the second slider 9. Two groups of first moving rods 15 and second moving rods 16 are jointly welded with a fixing plate 17. The fixing plate 17 is fixedly connected to the drilling rig frame 18 by bolts. A drilling machine is installed on the drilling rig frame 18. During operation, in the process of adjusting the drilling rig frame 18 by the existing positioning and adjusting device, it can usually only be adjusted in a single direction in the horizontal direction, resulting in poor adjustment effect. By driving the anchor pins 19 on the base 1 into the ground, the fixed connection between the adjusting device and the ground is realized. Then, the drilling rig frame 18 is connected to the fixing plate 17 by bolts, realizing the installation of the drilling machine on the adjusting device. In the process of adjusting the position of the drilling machine, by rotating the first knob 12, the first lead screw 11 is driven to rotate. While the first lead screw 11 rotates, it moves horizontally left and right. The first lead screw 11 pulls the first slider 6 to move left and right. The first slider 6 pulls the first moving rod 15 thereon to move left and right. The first moving rod 15 drives the fixing plate 17 to move left and right. The two groups of second moving rods 16 on the fixing plate 17 slide left and right in the two groups of second sliders 9, realizing the stable movement of the fixing plate 17. The fixing plate 17 drives the drilling rig frame 18 to move left and right, realizing the adjustment of the drilling rig frame 18 in the left and right directions.

[0020] By rotating the second knob 14, the second lead screw 13 is driven to rotate. While the second lead screw 13 rotates, it moves horizontally forward and backward. The second lead screw 13 pulls the second slider 9 to move forward and backward. The second slider 9 pulls the second moving rod 16 thereon to move forward and backward. The second moving rod 16 drives the fixing plate 17 to move forward and backward. The two groups of first moving rods 15 on the fixing plate 17 slide forward and backward within the two groups of first sliders 6, realizing the stable movement of the fixing plate 17. The fixing plate 17 drives the drilling rig frame 18 to move forward and backward, realizing the adjustment of the drilling rig frame 18 in the front-back direction; this structure can adjust the drilling rig frame 18 in the front-back, left-right directions, and can be arbitrarily adjusted in the horizontal direction, which is beneficial to improving the adjustment effect.

[0021] Please refer to Figures 4-5 As shown, four groups of anchor bolts 19 are welded on the base 1. A rod hole 20 is opened inside the anchor bolt 19. A third lead screw 21 passes through the rod hole 20. Threads are provided on the inner wall of the rod hole 20 and cooperate with the third lead screw 21 to slide. A third knob 22 is welded on the top side of the third lead screw 21. An installation groove 23 is opened inside the anchor bolt 19. A convex block 24 is slidably assembled inside the installation groove 23. The convex block 24 is rotatably connected to the third lead screw 21. Four groups of grooves 25 are opened on the side wall of the convex block 24. A ball 26 is assembled inside the groove 25. A telescopic nail 27 is welded on the ball 26. Four groups of through holes 28 are opened on the side wall of the anchor bolt 19. The telescopic nail 27 is assembled inside the through hole 28; during operation, in the process of positioning the drilling rig frame 18 by the existing positioning and adjusting device, since the drilling rig is prone to vibration during drilling, the positioning and adjusting device is prone to shaking, resulting in poor stability of the drilling rig frame 18. By driving the four anchor bolts 19 on the base 1 into the ground, then rotating the third knob 22 to drive the third lead screw 21 to rotate, the third lead screw 21 cooperates with the rod hole 20 through the thread to slide, the third lead screw 21 moves vertically downward, and drives the convex block 24 to move vertically downward. During the process of the convex block 24 moving vertically downward, the four balls 26 slide inside the grooves 25 of the convex block 24. The convex block 24 pushes the four telescopic nails 27 to move horizontally outward from the anchor bolt 19. The four telescopic nails 27 extend out of the through holes 28 and pierce into the soil on the ground, realizing the strengthening and fixing of the anchor bolt 19, making it difficult for the anchor bolt 19 to vibrate in the vertical direction, realizing the strengthening and fixing of the positioning and adjusting device and the ground, which is beneficial to improving the stability of the drilling rig frame 18.

[0022] Working principle: During the positioning process of the existing positioning and adjusting device for the drilling rig frame 18, since the drilling rig is prone to vibration during drilling, the positioning and adjusting device is likely to shake, resulting in poor stability of the drilling rig frame 18. By driving the four anchor bolts 19 on the base 1 into the ground, and then rotating the third knob 22, the third lead screw 21 is driven to rotate. The third lead screw 21 slides through the cooperation of the thread and the rod hole 20, and the third lead screw 21 moves vertically downward, driving the convex block 24 to move vertically downward. During the vertical downward movement of the convex block 24, the four ball bearings 26 slide in the groove 25 of the convex block 24, and the convex block 24 pushes the four expansion bolts 27 to move horizontally outward from the anchor bolts 19. The four expansion bolts 27 extend out from the through holes 28 and pierce into the soil on the ground, realizing the strengthening and fixing of the anchor bolts 19, making it difficult for the anchor bolts 19 to vibrate in the vertical direction, realizing the strengthening and fixing of the positioning and adjusting device to the ground, which is beneficial to improving the stability of the drilling rig frame 18. During the adjustment process of the existing positioning and adjusting device for the drilling rig frame 18, it can usually only be adjusted in a single direction horizontally, resulting in poor adjustment effect. By driving the anchor bolts 19 on the base 1 into the ground, the fixed connection between the adjusting device and the ground is realized. Then, the drilling rig frame 18 is connected to the fixing plate 17 through bolts, realizing the installation of the drilling rig on the adjusting device. During the process of adjusting the position of the drilling rig, by rotating the first knob 12, the first lead screw 11 is driven to rotate. While the first lead screw 11 rotates, it moves horizontally left and right. The first lead screw 11 pulls the first slider 6 to move left and right. The first slider 6 pulls the first moving rod 15 thereon to move left and right. The first moving rod 15 drives the fixing plate 17 to move left and right. The two groups of second moving rods 16 on the fixing plate 17 slide left and right in the two groups of second sliders 9, realizing the stable movement of the fixing plate 17. The fixing plate 17 drives the drilling rig frame 18 to move left and right, realizing the adjustment of the drilling rig frame 18 in the left and right directions.

[0023] By rotating the second knob 14, the second lead screw 13 is driven to rotate. While the second lead screw 13 rotates, it moves horizontally forward and backward. The second lead screw 13 pulls the second slider 9 to move forward and backward. The second slider 9 pulls the second moving rod 16 thereon to move forward and backward. The second moving rod 16 drives the fixing plate 17 to move forward and backward. The two groups of first moving rods 15 on the fixing plate 17 slide forward and backward in the two groups of first sliders 6, realizing the stable movement of the fixing plate 17. The fixing plate 17 drives the drilling rig frame 18 to move forward and backward, realizing the adjustment of the drilling rig frame 18 in the front and back directions. This structure can adjust the drilling rig frame 18 in the front, back, left, and right directions and can be adjusted arbitrarily horizontally, which is beneficial to improving the adjustment effect.
