Description

Technical Field

[0001] This utility model relates to the field of drilling technology, specifically to high-frequency drilling rigs. Background Technology

[0002] In engineering fields such as geological exploration, building construction, and mining, high-frequency drilling rigs are the core equipment for achieving efficient drilling operations. With their high-frequency vibration drilling characteristics, they can effectively cope with various complex strata (such as hard rock, sandy soil, weathered rock, etc.), significantly improving drilling efficiency and operation quality. They have become one of the indispensable key equipment in modern engineering construction.

[0003] As engineering projects continue to expand and the working environment becomes increasingly complex, the industry's performance requirements for high-frequency drilling rigs are becoming more and more stringent. Most existing high-frequency drilling rigs adopt a single drive mode (pure electric or pure manual). Although pure electric drive can achieve automated operation, the equipment will be completely unable to operate in the field when there is no power supply or power failure, which will seriously affect the progress of the project. Pure manual drive relies on manual operation, which is not only labor-intensive but also has low drive efficiency, making it difficult to meet the needs of large-scale, high-intensity drilling operations and restricting the adaptability of the equipment in different working scenarios.

[0009] A further improvement of this invention is that the locking component includes: The slide is horizontally mounted on the lifting box, with one end facing the rack; The locking tooth is located in the slide rail and moves away from or near the rack under the drive of the moving component. When the locking tooth moves away from or near the rack, the teeth on the locking tooth enter the tooth groove on the rack or disengage from the tooth groove.

[0010] A further improvement of this utility model is that the moving component includes; A cylindrical locking rod is slidably disposed in the slide rail and parallel to the length direction of the slide rail. A first channel is provided on the side of the locking teeth facing the locking rod. A boss is provided after the first end of the locking rod extends into the first channel. A second handle is provided after the second end of the locking rod passes through a baffle fixed in the slide rail. A barrier plate is installed in the slide rail and fixed on the locking rod between the locking teeth and the baffle. The two sides of the barrier plate are arc-shaped.

Detailed Implementation

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, in the following description, specific details such as particular system structures and technologies are set forth for illustrative purposes rather than for limiting purposes, in order to provide a thorough understanding of the embodiments of the present invention. However, those skilled in the art should understand that the present invention can also be implemented in other embodiments without these specific details.

[0018] The high-frequency drilling rig provided by this utility model, in conjunction with the appendix to the instruction manual... Figure 1 To be continued Figure 7 It can be seen that the high-frequency drilling rig mainly includes the following parts or components: base plate 10, lifting box 13, mounting plate 14, and locking assembly 50.

[0019] In this invention, a fixed plate 11 is vertically mounted on the base plate 10, and a rack 12 is fixedly mounted on it. The length direction of the rack 12 is parallel to the length direction of the fixed plate 11. A lifting box 13 is mounted on the fixed plate 11 and moves up and down along the length direction of the fixed plate 11 under the drive of the lifting assembly 20. The side of the lifting box 13 closest to the fixed plate 11 is open. A mounting plate 14 is fixedly connected to one side of the lifting box 13, and a drilling rig body 15 is mounted on the mounting plate 14. A locking assembly 50 is mounted on the lifting box 13 for locking the lifting box 13. The lifting assembly 20 specifically includes a first rotating shaft 21, a second rotating shaft 22, and a third rotating shaft 23. The rotating shaft 23 is arranged parallel to the top and bottom inside the lifting box 13. Its axial direction is perpendicular to the length direction of the fixed plate 11. Its two ends are connected to the rotating shafts on both sides of the lifting box 13. The first rotating shaft 21 rotates under the drive of the electric drive assembly 40. The first gear 211 can slide along the axial direction of the first rotating shaft 21 and meshes with the second gear 221 fixed on the second rotating shaft 22. The two third gears 231 fixed on the third rotating shaft 23 mesh with the second gear 221 and the rack 12 respectively. One end of the second rotating shaft 22 passes through the lifting box 13 and is fixed with a manual drive component 222.

[0020] The drilling rig body 15 is fixed to one side of the lifting box 13 via the mounting plate 14. The lifting box 13 is mounted on the fixed plate 11 via the lifting assembly 20. The side of the lifting box 13 closest to the fixed plate 11 has an opening to facilitate the engagement of the internal gears with the rack 12 on the fixed plate 11. At this time, the locking assembly 50 is in an unlocked state, and the lifting box 13 can move freely up and down along the length of the fixed plate 11. When the electric drive assembly 40 is started, it drives the first rotating shaft 21 to rotate. Since the first gear 211 maintains axial sliding engagement with the first rotating shaft 21 through a sliding structure and rotates synchronously, the first gear 211 and the second gear 221 on the second rotating shaft 22 are in a meshing state. The power of the first rotating shaft 21 is transmitted to the second rotating shaft 22 through the first gear 211 and the second gear 221. When the second rotating shaft 22 rotates, it drives the second gear 221 on it to rotate synchronously, thereby driving one of the third gears 231 on the third rotating shaft 23 to rotate, so that the third rotating shaft 23 rotates as a whole. The two third gears 231 on the third rotating shaft 23 mesh with the rack 12 on the fixed plate 11, so that it rolls along the length direction of the rack 12, driving the entire lifting box 13 (and the drilling body 15 on the mounting plate 14) to rise or fall along the length direction of the fixed plate 11 (the lifting direction is controlled by the forward and reverse rotation of the electric drive assembly 40).

[0021] When there is no power supply or fine adjustments are required, the sliding structure allows the first gear 211 to slide axially along the first rotating shaft 21, disengaging from the second gear 221. The operator then rotates the manual drive component 222 at the end of the second rotating shaft 22, directly rotating the second rotating shaft 22. The subsequent power transmission path is consistent with the electric drive, ultimately achieving the lifting and adjusting of the lifting box 13 and the drilling rig body 15. This effectively improves the equipment's adaptability in complex environments. After the drilling rig body 15 is adjusted to the target height by the lifting assembly 20, the locking assembly 50 on the lifting box 13 is operated to lock the relative position of the lifting box 13 and the fixed plate 11, so as to prevent the lifting box 13 from moving accidentally during drilling operations and ensure the stable operation of the drilling rig body 15.

[0022] Specifically, the manual drive component 222 is a handwheel.

[0023] As one embodiment, in conjunction with the appendix to the specification Figure 3 It can be seen that the first gear 211 slides along the axial direction of the first rotating shaft 21 under the drive of the sliding component 30. The sliding component 30 includes a rotating sleeve 31, which is coaxially sleeved on the first rotating shaft 21. The first gear 211 is fixed on the rotating sleeve 31. An annular groove 311 is provided on the rotating sleeve 31 on one side of the first gear 211. The insertion rod 32 is horizontally arranged in the lifting box 13 and parallel to the first rotating shaft 21. Two push rods 321 are fixed at its first end. The push rods 321 are perpendicular to the insertion rod 32. The two push rods 321 extend into both sides of the annular groove 311. The outer surface of the push rods 321 contacts the inner wall of the annular groove 311. The second end of the insertion rod 32 passes through the lifting box 13 and is provided with a first handle 33. A nut is provided on the insertion rod 32 on the outside of the lifting box 13. The nut is threadedly connected to the threaded section on the insertion rod 32.

[0024] The rotating sleeve 31 is coaxially sleeved on the first rotating shaft 21, and the first gear 211 is fixed on the rotating sleeve 31. At this time, the first gear 211 and the second gear 221 are in a meshing (or disengaging) state. The two push rods 321 on the insertion rod 32 extend into both sides of the annular groove 311 of the rotating sleeve 31. The outer surface of the push rod 321 contacts the inner wall of the groove. The nut is threadedly connected to the threaded section of the insertion rod 32 and abuts against the outside of the lifting box 13 to lock the current position.

[0025] During switching, loosen the nut to move it away from the lifting box 13, grasp the first handle 33, and push or pull the insertion rod 32 along the axial direction of the first rotating shaft 21. Since the two push rods 321 extend into both sides of the annular groove 311 and contact the inner wall of the groove, the axial movement of the insertion rod 32 will drive the rotating sleeve 31 to slide synchronously along the axial direction of the first rotating shaft 21 through the push rods 321, thereby driving the first gear 211 fixed on the rotating sleeve 31 to move axially. When the first gear 211 moves to the target position of fully engaging with the second gear 221 (when electrically driven) or fully disengaging (when manually driven), stop moving the insertion rod 32, tighten the nut to make it press against the outside of the lifting box 13 again, and lock the position of the insertion rod 32 through the threaded engagement.

[0026] Specifically, the two push rods 321 do not restrict the rotation of the rotating sleeve 31.

[0027] Specifically, a guide groove 212 is provided on the first rotating shaft 21 along its axial direction, and the guide key on the rotating sleeve 31 is slidably connected to the guide groove 212.

[0028] As one embodiment, in conjunction with the appendix to the specification Figure 4 It is known that the electric drive assembly 40 includes a worm gear 41, which is fixed at the end of the first rotating shaft 21; the worm 42 is located in the lifting box 13 and rotates under the drive of the motor 43, and the worm 42 meshes with the worm gear 41.

[0029] Motor 43 drives worm 42 to rotate, worm 42 drives worm wheel 41 to rotate, and worm wheel 41 drives first rotating shaft 21 to rotate.

[0030] As one embodiment, in conjunction with the appendix to the specification Figure 5 To be continued Figure 7It is known that the locking component 50 includes a slide rail 51, horizontally mounted on the lifting box 13, with one end facing the rack 12; locking teeth 52 are located within the slide rail 51, and under the drive of the moving component, move away from or towards the rack 12 within the slide rail 51. When the locking teeth 52 move away from or towards the rack 12, the teeth on the locking teeth 52 enter or disengage from the tooth grooves on the rack 12. The moving component includes a cylindrical locking rod 53, slidably mounted within the slide rail 51 and parallel to the length direction of the slide rail 51. A first channel 521 is provided on the side of the locking teeth 52 facing the locking rod 53. A boss 531 is provided after the first end of the locking rod 53 extends into the first channel 521. A second handle 532 is provided after the second end of the locking rod 53 passes through a fixed baffle 54 within the slide rail 51. A blocking plate 55 is located within the slide rail 51 and fixed on the locking rod 53 between the locking teeth 52 and the baffle 54. The two sides of the blocking plate 55 are arc-shaped. Two locking grooves 56 are provided on both sides of the slide 51 between the tooth 52 and the baffle 54. When the locking rod 53 rotates, the two arcs enter and disengage from the two locking grooves 56 respectively. The pressure plate 57 is located in the slide 51, slides between the baffle 54 and the second handle 532, and is connected to the pivot of the locking rod 53. When the locking rod 53 moves, it drives the pressure plate 57 to move synchronously. The spring 58 is sleeved on the locking rod 53 between the baffle 54 and the pressure plate 57. Its first end is connected to the baffle 54 and its second end is connected to the pressure plate 57.

[0031] When locked, push the second handle 532. At this time, the spring 58 is compressed. The boss 531 at the first end of the locking rod 53 pushes the locking tooth 52 along the slide 51 toward the rack 12 through the first channel 521 of the locking tooth 52 until the teeth on the locking tooth 52 are completely embedded in the tooth groove of the rack 12, thus initially realizing mechanical engagement and locking. Rotate the second handle 532 to drive the locking rod 53 and the fixed barrier plate 55 to rotate synchronously, so that the arc on both sides of the barrier plate 55 is inserted into the locking groove 56 on both sides of the slide 51, forming a secondary lock and completing the secure locking of the lifting box 13.

[0032] When unlocking, the second handle 532 is rotated in the opposite direction, causing the arc of the barrier plate 55 to disengage from the locking groove 56 of the slide rail 51, thus releasing the secondary lock. At this time, the spring 58 relaxes, pulling the second handle 532, which in turn moves the pressure plate 57 and the locking rod 53 along the slide rail 51 away from the rack 12. Simultaneously, the protrusion 531 at the first end of the locking rod 53 pulls the locking teeth 52 backward through the first channel 521 until the teeth of the locking teeth 52 are completely disengaged from the tooth groove of the rack 12. At this time, the lifting box 13 can be freely raised and lowered along the fixed plate 11.

[0033] As one embodiment, in conjunction with the appendix to the specification Figure 1 It can be seen that two slide rails 111 are provided on both sides of the fixed plate 11 along its length direction, and multiple pulleys 112 are provided on both sides of the upper end and the lower end of the lifting box 13. The pulleys 112 are slidably connected to the corresponding slide rails 111.

[0034] When the lifting assembly 20 drives the lifting box 13 to rise or fall along the length of the fixed plate 11, multiple pulleys 112 on the upper and lower sides of the lifting box 13 are respectively embedded in the corresponding slide rails 111 on both sides of the fixed plate 11. As the lifting box 13 moves, it rolls along the length of the slide rails 111. During the rolling process, the slide rails 111 limit and guide the pulleys 112, restricting the lifting box 13 from deviating (such as swaying left and right) in the direction perpendicular to the length of the fixed plate 11. At the same time, the rolling contact between the pulleys 112 and the slide rails 111 converts the sliding friction between the lifting box 13 and the fixed plate 11 into rolling friction, reducing the resistance during the lifting process. This makes the lifting or lowering action of the lifting box 13 more stable and smooth, avoiding lifting jamming due to excessive friction or uneven force, thereby ensuring the stability of the drilling rig body 15 during the height adjustment process.
