Detailed Implementation

[0023] The present invention will be further described in detail below with reference to embodiments:

[0024] like Figures 1-4 As shown, this utility model provides a lifting mechanism for a multi-arm anchor drilling rig, including a body 1. Movable tracks 2 are installed on both sides of the lower end of the body 1. A lifting mechanism 3 is provided at the upper end of the body 1. An installation platform 4 is installed at the top of the lifting mechanism 3. A control box 5 is fixedly installed on one side of the upper end of the installation platform 4. A rotating platform 6 is fixedly installed on the other side of the upper end of the body 1. An adjusting arm mechanism 7 is installed at the upper end of the rotating platform 6.

[0025] A rotary support 8 is rotatably mounted on the top of the fixed base 67, and a slide 9 is fixedly mounted on the top of the rotary support 8. A drill arm 10 is mounted on the front side of the slide 9.

[0026] A set of hinge seats 610 is fixedly provided at the lower end of the slewing support 8. The top of the output rod of the adjusting cylinder 611 is rotated and installed with the inner side of the hinge seats 610 provided on the slewing support 8. The adjusting cylinder 611 cooperates with the hinge seats 610 to make the slewing support 8 swing up and down.

[0027] In this design, the rotating platform 6 can drive the main arm 63 and the drill arm 10 to rotate, further improving the drilling efficiency of the device.

[0028] like Figure 3As shown, the lifting mechanism 3 includes a groove 31, which is symmetrically opened on both sides of the upper end of the body 1. A dual-axis motor 32 is fixedly installed in the middle of the groove 31. A lead screw 33 is rotatably installed on both sides of the dual-axis motor 32. A movable seat 34 is threaded on the outside of the lead screw 33. A rotating seat 35 is fixedly installed at the upper end of the movable seat 34. A support plate 36 is rotatably installed on the inner side of the rotating seat 35. A rotating seat 37 is rotatably installed at the top of the support plate 36.

[0029] The top end of the lead screw 33 is rotatably connected to the inner walls of both sides of the groove 31, and the movable seat 34 slides within the groove 31.

[0030] The bottom end of the rotating seat 37 is symmetrically and fixedly connected to the bottom end of the mounting platform 4.

[0031] In this scheme, the rotating lead screw 33 drives the threaded movable seats 34 on both sides to move closer to each other. With the cooperation of rotating seat 1 35 and rotating seat 2 37, the movable seat 34 can push the support plate 36 upward, so that the support plate 36 can push the mounting platform 4 upward simultaneously. In this way, the main arm 63 and the drill arm 10 can be lifted to the required height to meet the drilling needs of the drilling rig and avoid affecting the overall work efficiency.

[0032] like Figure 4 As shown, the adjusting arm mechanism 7 includes a mounting base 61, the lower end of which is rotatably mounted to the top of the rotating platform 6. A movable frame 62 is fixedly mounted on the right end of the mounting base 61. A main arm 63 is rotatably mounted on the inner side of the movable frame 62. A first hinge seat 64 is fixedly mounted on both the mounting base 61 and the main arm 63. A lifting cylinder 65 is rotatably mounted on the inner side of the first hinge seat 64. A telescopic arm 66 is movably mounted inside the main arm 63. A fixed seat 67 is fixedly mounted at the top of the telescopic arm 66. A second hinge seat 68 is fixedly mounted on the outer walls of both the front and rear sides of the main arm 63 and the telescopic arm 66. A telescopic cylinder 69 is rotatably mounted on the inner side of the second hinge seat 68. A third hinge seat 610 is fixedly mounted on the lower side of the top of the telescopic arm 66. An adjusting cylinder 611 is rotatably mounted on the inner side of the third hinge seat 610.

[0033] The hinge seat 64 is located on the upper side of the mounting base 61 and the main boom 63. The lifting cylinder 65 works with the movable frame 62 to allow the main boom 63 to swing left and right.

[0034] The second hinge seat 68 is located on the front and rear sides of the main arm 63 and the telescopic arm 66. The telescopic cylinder 69 cooperates with the second hinge seat 68 to enable the telescopic arm 66 to slide.

[0035] In this solution, by adjusting the arm structure, the lifting height of the drill arm 10 is not only greatly increased, but also flexible adjustments at multiple angles and in all directions are achieved, significantly improving the applicability of the drilling rig.

[0036] The working principle of the lifting mechanism of the multi-arm anchor drilling rig will be explained in detail below.

[0037] like Figures 1-4 As shown, when the multi-arm anchor bolt drilling rig is in use, after the drilling rig travels to the designated drilling area, the height of the mounting platform 4 and the drill arm 10 can be adjusted according to the drilling requirements. By starting the dual-axis motor 32, the dual-axis motor 32 drives the lead screws 33 on both sides to rotate. The lead screws 33 drive the threaded movable seats 34 on both sides to move closer to each other. With the cooperation of the rotating seat 1 35 and the rotating seat 2 37, the movable seats 34 can push the support plate 36 upward, so that the support plate 36 can simultaneously push the mounting platform 4 upward. In this way, the main arm 63 and the drill arm 10 can be lifted to the required height to meet the drilling requirements of the drilling rig. To meet drilling requirements and avoid impacting overall work efficiency, the telescopic cylinder 69 is activated. The output rod of the telescopic cylinder 69 pushes the telescopic arm 66 upward, causing the telescopic arm 66 to drive the slewing support 8 and the slide 9 to move synchronously. This allows adjustment of the drilling arm 10's position. Activating the lifting cylinder 65 allows the main arm 63 to swing left and right in coordination with the rotation of the movable frame 62, thus adjusting the position of the drilling arm 10. At this time, the adjusting cylinder 611 can be used to push the slide 9 to swing up and down, further adjusting the angle between the slide 9 and the drilling arm 10, ensuring efficient drilling operations.

[0038] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
