Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1-5 This invention provides a technical solution: a drill pipe support for petroleum geological exploration, including a base box 1 and a fixed plate 2 fixedly connected to the top of the base box 1, an adjustment mechanism 3 and a movable frame 4, a support plate 5 fixedly connected between one side of two adjacent movable frames 4, placement holes 6 are provided at the top and bottom of the movable frame 4 and the support plate 5 and the top of the fixed plate 2, and an elastic pad is fixedly connected inside the placement hole 6. The elastic pad can protect the placed drill pipe.

[0028] In this embodiment of the invention, the adjusting mechanism 3 includes a fixed column 31. A threaded groove 32 is provided inside the fixed column 31. The top and bottom of the inner wall of the threaded groove 32 are threadedly connected to threaded columns 33 that extend to the outside of the fixed column 31. An insert block 34 is fixedly connected to one end of the threaded column 33 located outside the fixed column 31. Movable grooves 35 are provided inside the fixed column 31 and on both sides of the threaded groove 32. A buffer spring 36 is movably connected inside the movable groove 35. Limiting rods 37 are fixedly connected to both ends of the buffer spring 36. One end of the limiting rod 37 extends through the movable groove 35 and to the outside of the movable groove 35. A toggle rod 38 extending to the front of the limiting rod 37 is fixedly connected to the front of the fixed column 31. Sliding grooves 39 that are adapted to the toggle rod 38 are provided on both sides of the surface of the fixed column 31. A limiting frame 310 is slidably connected between the two sides of the front of the fixed column 31 and between the opposite sides of the two sliding grooves 39.

[0029] In this embodiment of the invention, slots 9 adapted to the insert block 34 are provided on both sides of the top and bottom of the movable frame 4 and on both sides of the top of the fixed plate 2. A limiting groove 8 adapted to the limiting rod 37 is provided on the side of the insert block 34 near the threaded post 33.

[0030] In this embodiment of the invention, elastic pads are fixedly connected to both sides of the insert block 34, and a motor 7 is fixedly connected to the bottom of the inner wall of the base box 1. One end of the output shaft of the motor 7 is fixedly connected to the first pulley 10 through a coupling. The motor 7 is a three-phase asynchronous motor, which can adjust the speed and perform forward and reverse rotation.

[0031] In this embodiment of the invention, a rotating rod 11 is rotatably connected to the bottom of the inner wall of the bottom box 1 via a support cylinder, and a second pulley 12 is fixedly connected to the middle of the surface of the rotating rod 11.

[0032] In this embodiment of the invention, the surface of the second pulley 12 is connected to the surface of the first pulley 10 via a belt, and both ends of the rotating rod 11 are fixedly connected with the first bevel gear 13.

[0033] In this embodiment of the invention, both sides of the bottom of the inner wall of the base box 1 are rotatably connected by bearings to threaded sleeves 14 that extend to the top of the base box 1. The surface of the threaded sleeves 14 located inside the base box 1 is fixedly connected to a second bevel gear 15 that meshes with the first bevel gear 13.

[0034] In this embodiment of the invention, the threaded sleeve 14 is internally threaded with a threaded rod 16. The top end of the threaded rod 16 is fixedly connected to a sliding rod 17 via a connecting rod. The bottom end of the sliding rod 17 is slidably connected to the surface of the threaded sleeve 14 located on the top of the base box 1. This allows the height of the threaded rod 16 to be adjusted according to the height of the movable frame, thereby facilitating the limiting protection of both sides of the movable frame 4.

[0035] In this embodiment of the invention, both sides of the movable frame 4 are fixedly connected with arc-shaped ring plates 18, and the inner wall of the arc-shaped ring plates 18 is fixedly connected with a protective pad 19. The protective pad 19 can prevent the arc-shaped ring plates 18 from rubbing against the contact surface.

[0036] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0037] In use, adjust the distance between the movable frame 4 and the support plate 5 according to the diameter of the drill rod. The operator rotates the threaded column 33, causing it to rotate out of the threaded groove 32. After rotating a certain distance according to the drill rod diameter, stop rotating. The limiting rod 37 inside the movable groove 35, through the buffering force of the buffer spring 36, inserts into the limiting groove 8 of the insert block 34, preventing the threaded column 33 from rotating under pressure. The limiting frame 310 limits the two actuating rods 38 when rotating the threaded column 33, preventing the limiting rod 37 from affecting the normal rotation of the threaded column 33. After both threaded columns 33 inside the fixed column 31 have rotated to the same height, insert the insert block 34. The drill rod is then fixed inside the slot 9 on the movable frame 4. The drill rod is then placed inside the placement hole 6. Depending on the number of drill rods, the number of movable frames 4 and adjusting mechanisms 3 can be increased to accommodate more drill rods. Arc-shaped ring plates 18 are provided on both sides of the movable frame 4 to facilitate limiting and protecting it. The motor 7 is started, causing it to drive the rotating rod 11 to rotate via the first pulley 10 and the second pulley 12. The rotating rod 11 then rotates via the first bevel gear 13 and the second bevel gear 15. The second bevel gear 15 drives the threaded sleeve 14 to rotate. Simultaneously, the threaded rod 16 inside the threaded sleeve 14 moves upward, allowing for the placement of more movable frames 4.
