Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.
[0022] like Figures 1 to 4 As shown, the core drilling rig inclination adjustment device includes a base 1. A rotating shaft 21 is rotatably mounted on one end of the base 1. A track 22 is vertically fixed on the rotating shaft 21. A slide block 23 is fitted on the track 22. Both the track 22 and the slide block 23 have a square structure. A machine head assembly is fixedly mounted on the slide block 23. An adjustment drive device is installed between the slide block 23 and the rotating shaft 21. A first support device is installed between the middle of the slide block 23 and the middle of the base 1. A second support device is installed between the top of the track 22 and the other end of the base 1. A fine-tuning locking device is installed on the second support device.
[0023] The adjustment drive device includes two adjusting cylinders 3 fixedly mounted on the slide 23 and located on both sides of the track 22. The outer end of the piston rod of the adjusting cylinder 3 extends toward and connects to the rotating shaft 21. The first support device includes a support rod 41 with one end hinged to the middle of the slide 23 and the other end hinged to the middle of the base 1. A crossbeam 42 is installed in the middle of the base 1, and a hinge seat is installed on the crossbeam 42. A hinge seat is also installed in the middle of the slide 23. One end of the support rod 41 is hinged to the hinge seat on the crossbeam 42, and the other end of the support rod 41 is hinged to the hinge seat on the slide 23.
[0024] The second support device includes a telescopic inner rod 51 and a telescopic outer rod sleeved together. The free end of the telescopic inner rod 51 is hinged to the top of the track 22, and the free end of the telescopic outer rod is hinged to one end of the base 1. The fine-tuning locking device is installed on the telescopic outer rod. The telescopic outer rod includes a first outer rod 52 and a second outer rod 53. The first outer rod 52 is sleeved outside the telescopic inner rod 51. The fine-tuning locking device includes a bidirectional adjusting screw 54 threaded between the first outer rod 52 and the second outer rod 53. Two locking nuts 55 are installed on the bidirectional adjusting screw 54, which respectively abut against the ends of the first outer rod 52 and the second outer rod 53.
[0025] The telescopic outer rod is equipped with a locking device that can lock the telescopic inner rod 51. The locking device includes a fixing hoop (not shown in the figure) fixedly installed at the upper end of the telescopic outer rod and located on one side of the telescopic inner rod 52. A locking hoop (not shown in the figure) is installed on the fixing hoop on the other side of the telescopic inner rod. A locking bolt (not shown in the figure) is installed between the locking hoop and the fixing hoop. The fixing hoop is welded to the end of the telescopic outer rod, and the locking hoop is hinged to the fixing hoop. Both the locking hoop and the fixing hoop are semi-circular, and the spliced ends after they are fastened together are connected by the locking bolt.
[0026] The head assembly includes a head seat 62 fixedly mounted on the slide 23, and a head 61 is mounted on the head seat 62. Two rotating shaft seats 21 are fixedly mounted on both sides of the base 1, and the two ends of the rotating shaft 21 extend into the two rotating shaft seats 21 respectively. A rotating bearing is installed between the rotating shaft 21 and the rotating shaft seat 21.
[0027] When the machine needs to be laid down, first disconnect the connection between the telescopic inner rod 51 and the track 22 in the second support device, then disconnect the connection between the support rod 41 and the slide 23 in the first support device. Adjust the piston rod of the hydraulic cylinder 3 to retract, causing the slide 23 and the machine head assembly to move downwards along the track 22, lowering the machine head assembly to a position close to the base 1. The track 22 then drives the rotating shaft 21 to rotate, placing it in a lying position. Figure 2 As shown, due to structural limitations, track 22 cannot move to a position close to base 1. Therefore, when track 22 rotates to the right and falls back to its lowest position, the end of track 22 is supported by pads. When the equipment needs to be erected again, as... Figure 3 As shown, the piston rod of the adjusting cylinder 3 extends outward, pushing the slide block 23 and the head assembly to slide to the right along the track 22. When the slide block 23 moves to a position sufficient to connect the support rod 41, the adjusting cylinder 3 stops working, hinges the free end of the support rod 41 to the slide block 23, and then the piston rod of the adjusting cylinder 3 retracts. Under the action of the support rod 41, the track 22 drives the rotating shaft 21 to rotate and rise, slowly supporting the track 22. When the track 22 moves to a position where it can be connected to the second support device, the two are connected. Then the adjusting cylinder 3 continues to work, slowly adjusting the angle of the track 22. At the same time, the track 22 pulls the telescopic inner rod 51 out from the telescopic outer rod. When the desired drilling angle is reached, the adjusting cylinder 3 stops working, and the telescopic inner rod 51 is manually operated to extend or retract within the telescopic outer rod to further fine-tune the drilling angle, so that the drilling angle error is basically within 0.5°. After locking the telescopic inner rod using the locking device, fine-tune it by rotating the bidirectional adjusting screw 54. The two ends of the bidirectional adjusting screw 54 push outwards or pull inwards to tighten the first outer rod 52 and the second outer rod 53, ensuring the drilling angle reaches the precise required angle. After fine-tuning, lock the positions of the first outer rod 52 and the second outer rod 53 using the locking nut 55.
[0028] The method for measuring the drilling angle, specifically the inclination angle between the drilling head assembly and the track 22, is a well-known technique in the art. Specifically, the method involves placing the side of the geological compass close to the track 22 and oscillating the pointer with the bubble on the back of the compass until it is horizontal; this angle is the inclination angle. The above describes the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made without departing from the spirit and scope of this utility model, and all such changes and modifications fall within the scope of the claimed utility model.
