Abstract
Description
Technical Field
[0001] This invention relates to the field of support device technology, and in particular to a telescopic down-the-hole drill support device. Background Technology
[0002] In mining, infrastructure construction, and large-scale engineering drilling operations, down-the-hole (DH) rigs are core drilling equipment, and their operational stability, positioning accuracy, and construction efficiency directly affect project quality and progress. Currently, when DH rigs are operating on-site, they mostly rely on scaffolding as the main support structure. By erecting specialized scaffolding, a working platform and stable support are provided for the DH rig, ensuring that it does not deviate during drilling and thus guaranteeing the smooth progress of drilling operations.
[0003] However, existing scaffolding-based down-the-hole drill support methods are highly dependent on the accuracy of scaffolding erection. Parameters such as the spacing between uprights, the step distance of horizontal bars, verticality, and flatness of the scaffolding must strictly comply with construction specifications and undergo professional acceptance before use. The erection process not only requires professional scaffolders but also consumes significant manpower, material resources, and time. Even slight deviations in scaffolding erection can easily cause the down-the-hole drill's tilt angle to deviate from the ideal value, thus affecting the stability and safety of subsequent drilling operations. Therefore, this invention proposes a telescopic down-the-hole drill support device. Summary of the Invention

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Example
[0023] like Figure 1 and Figure 2 As shown, the present invention proposes a telescopic down-the-hole drill support device, including a base frame 1, which provides basic support for the device and supports all subsequent connecting components. A top frame 2 is provided above the base frame 1. The top frame 2 is used to support the motor 3 and the down-the-hole drill and cooperates with the adjustment mechanism 5 to realize angle adjustment. The motor 3 is installed on the top frame 2. The motor 3 provides drilling power for the down-the-hole drill and ensures continuous operation. The output end of the motor 3 is connected to the down-the-hole drill. The telescopic adjustment of the base frame 1 and the top frame 2 changes the overall length of the device to adapt to the spatial size requirements of different construction sites.
[0024] The base frame 1 includes two sets of first square tubes 11, which serve as the core load-bearing members and provide a sliding guide foundation for the second square tubes 13. A connecting pipe 12 is fixedly connected to one end of each set of first square tubes 11, rigidly connecting them and fixing the distance between them to ensure the lateral stability of the overall structure of the base frame 1. Second square tubes 13 are slidably connected to each of the two sets of first square tubes 11. The second square tubes 13 work in conjunction with the first square tubes 11 to allow for the extension and retraction of the base frame 1. The extension length of the second square tubes 13 is adjusted by sliding within the first square tubes 11 to precisely adapt to the distance requirements of different work points. A fixing pipe 14 is fixedly connected between the two sets of second square tubes 13, simultaneously locking their relative positions and fixing the distance between them. This ensures the stability of the overall structure of the base frame 1 and prevents the device from shaking due to member misalignment during operation. The first square tube 11 has multiple sets of equidistantly distributed first through holes 111. The first through holes 111 provide a passage for bolts to pass through and realize multi-level length positioning. The second square tube 13 has a first threaded hole 131 corresponding to the first through hole 111. The first threaded hole 131 and the bolt cooperate to form a rigid locking structure. By passing the bolt through the first through hole 111 and threading it into the first threaded hole 131, the length of the second square tube 13 extending out of the first square tube 11 is fixed, so that the overall length of the device is fixed and the bottom frame 1 is prevented from expanding and contracting during the drilling process.
[0025] The top frame 2 includes two sets of third-party tubes 21, which serve as the main support structure of the top frame 2 and provide sliding tracks for the fourth-party tube 23. A connecting plate 22 is fixedly connected to one end of each set of third-party tubes 21, securing them together. The connecting plate 22 also fixes the spacing between the two sets of third-party tubes 21, ensuring the lateral structural strength of the top frame 2. The third-party tube 21 has a U-shaped structure, which provides a limiting guide for the fourth-party tube 23, preventing it from falling off during sliding. The fourth-party tube 23 is slidably connected within the third-party tube 21. The fourth-party tube 23 cooperates with the third-party tube 21 to achieve the extension and retraction of the top frame 2. The fourth-party tube 23 slides to adjust its extension length beyond the third-party tube 21 to match the extension and retraction length of the bottom frame 1 and adapt to the working stroke of the down-the-hole drill. A fixing plate 24 is fixedly connected between the two sets of fourth square tubes 23. The fixing plate 24 strengthens the connection between the two sets of fourth square tubes 23 and fixes the spacing between the two sets of fourth square tubes 23, ensuring the structural stability of the top frame 2 after expansion and contraction. Multiple sets of equidistant second through holes 211 are provided on the third square tube 21. The second through holes 211 provide positioning holes for bolts, enabling multi-position length adjustment of the top frame 2. Second threaded holes 231 corresponding to the second through holes 211 are provided on the fourth square tube 23. The second threaded holes 231 are threaded with bolts to form a locking mechanism for the length of the top frame 2. By passing the bolt through the second through hole 211 and threading it into the second threaded hole 231, the length of the fourth square tube 23 extending beyond the third square tube 21 is fixed, thus fixing the length of the top frame 2 and preventing displacement of the top frame 2 during down-the-hole drilling operations.
[0026] For further details, please refer to Figure 1 , Figure 2 and Figure 5 Mounting plates 31 are installed on two sets of fourth square tubes 23. The mounting plates 31 provide a stable mounting platform for the motor 3, ensuring the coaxiality of the motor 3 during operation. The motor 3 is mounted on the mounting plates 31. First connecting blocks 32 are fixedly connected to both sides of the mounting plates 31. The first connecting blocks 32 are L-shaped, and the L-shaped first connecting blocks 32 enable the mounting plates 31 and the fourth square tubes 23 to slide and engage. The two sets of first connecting blocks 32 are located on the opposite side of the two sets of fourth square tubes 23 and slide with them. The first connecting blocks 32 allow the mounting plates 31 to slide on the two sets of fourth square tubes 23, facilitating the adjustment of the horizontal working position of the motor 3 and the down-the-hole drill. A guide plate 33 is fixedly connected to the side of the connecting plate 22. The guide plate 33 provides vertical guidance support for the down-the-hole drill. The guide plate 33 has a guide hole 34, which precisely defines the drilling trajectory of the down-the-hole drill. The down-the-hole drill connected to the output end of the motor 3 drills after passing through the guide hole 34, effectively improving the accuracy of hole positioning.
[0027] Furthermore, such as Figures 1 to 3As shown, the aforementioned support device includes a connecting component 4 connected to one end of the bottom frame 1 and the top frame 2. The connecting component 4 achieves a flexible connection between the bottom frame 1 and the top frame 2, and simultaneously performs height adjustment and rotation functions. The connecting component 4 includes two sets of fifth square tubes 41 fixedly connected to the top of the connecting tube 12. The fifth square tubes 41 provide vertical sliding guides for the sixth square tubes 42, and the positions of the fifth square tubes 41 are fixed. The sixth square tubes 42 are slidably connected to the two sets of fifth square tubes 41 respectively. The sixth square tubes 42 and the fifth square tubes 41 cooperate to achieve height adjustment at one end of the top frame 2. The tops of the two sets of sixth square tubes 42 are fixedly connected to a central tube 43. The central tube 43 synchronously links the lifting and lowering movements of the two sets of sixth square tubes 42, and through the central tube 43, the two sets of sixth square tubes 42 move synchronously, ensuring the consistency of height adjustment at one end of the top frame 2. A sleeve 44 is fitted around the outer rotating ring of the central tube 43. The sleeve 44 provides rotational support for the top frame 2. The sleeve 44 is located between two sets of sixth square tubes 42. The sleeve 44 rotates in its original position to ensure that the rotation of the top frame 2 does not cause the central tube 43 and the sixth square tubes 42 to rotate. Two sets of fixing blocks 45 are fixedly connected to the top of the sleeve 44. The fixing blocks 45 rigidly connect the sleeve 44 to the top frame 2. The two sets of fixing blocks 45 are respectively fixedly connected to the third third tube 21. The third third tube 21 is fixed to the sleeve 44 through the fixing blocks 45, so that the top frame 2 rotates around the central tube 43, realizing the horizontal angle adjustment of the down-the-hole drill. The fifth square tube 41 has equidistantly distributed third through holes 411. The third through holes 411 provide multi-position height positioning holes for bolts. The sixth square tube 42 has third threaded holes corresponding to the third through holes 411. The third threaded holes cooperate with the bolts to lock the extension length of the sixth square tube 42. By threading the bolt through the third through hole 411 and connecting it to the third threaded hole, the length of the sixth square tube 42 extending out of the fifth square tube 41 is fixed, thereby adjusting the height of one end of the top frame 2 to adapt to drilling operation requirements of different heights.
[0028] Specifically, such as Figures 1 to 5 As shown, the aforementioned support device includes an adjustment mechanism 5 disposed between the bottom frame 1 and the top frame 2. The adjustment mechanism 5 is used to adjust the inclination of the top frame 2 to change the drilling angle of the down-the-hole drill, thereby enabling multi-angle drilling operations. The adjustment mechanism 5 includes a rotating tube 51 that passes through two sets of second square tubes 13. The rotating tube 51 provides the core rotation fulcrum for the adjustment mechanism 5. The rotating tube 51 is rotatably connected to the second square tubes 13. Two sets of first positioning rings 514 are fixedly connected to the outer ring of the rotating tube 51. The first positioning rings 514 limit the axial position of the rotating tube 51. The two sets of first positioning rings 514 are disposed on opposite sides of the two sets of second square tubes 13. The first positioning rings 514 ensure that the rotating tube 51 remains in its original position and prevents axial movement.
[0029] Two sets of seventh square tubes 52 are fixedly connected to the rotating tube 51. The seventh square tubes 52 provide vertical sliding guides for the eighth square tubes 53. The eighth square tubes 53 are slidably connected to the two sets of seventh square tubes 52 respectively. The eighth square tubes 53 and the seventh square tubes 52 cooperate to achieve length compensation when the top frame 2 is tilted. The eighth square tubes 53 slide in the seventh square tubes 52. The tops of the two sets of eighth square tubes 53 are fixedly connected to a movable plate 54. The movable plate 54 connects the two sets of eighth square tubes 53 into one unit and carries the second connecting block 55. The two ends of the movable plate 54 are respectively fixedly connected to the second connecting block 55. The second connecting block 55 is L-shaped. The L-shaped second connecting block 55 realizes the sliding cooperation between the movable plate 54 and the fourth square tube 23. The two sets of second connecting blocks 55 are set on the side of the two sets of fourth square tubes 23 that are far apart and slide with them. The movable plate 54 slides on the bottom of the two sets of fourth square tubes 23 through the two sets of second connecting blocks 55. When the top frame 2 is deflected, the eighth square tube 53 slides in the seventh square tube 52, and at the same time the second connecting block 55 slides on the fourth tube 23, ensuring the smoothness of the tilt adjustment of the top frame 2.
[0030] Furthermore, the adjustment mechanism 5 also includes two sets of positioning plates 56 fixedly connected to the bottom of the fixed plate 24. The positioning plates 56 provide rotational support points for the connecting rod 57. The connecting rod 57 passes through the two sets of positioning plates 56. The connecting rod 57 connects the two sets of positioning plates 56 and provides an installation base for the support frame 58. The connecting rod 57 is connected to the top frame 2 through the positioning plates 56. Support frames 58 are connected to both ends of the connecting rod 57. The support frames 58 provide tilt support for the top frame 2 and transmit adjustment force. The support frame 58 includes a first rotating plate 581 rotatably connected to the connecting rod 57. The first rotating plate 581 is the core connecting rod of the support frame 58 and transmits tilt adjustment torque. Second positioning rings 515 are fixedly sleeved on both ends of the connecting rod 57. The second positioning rings 515 limit the axial position of the first rotating plate 581. The support frame 58 is set between the positioning plate 56 and the second positioning rings 515. The setting of the second positioning rings 515 makes one end of the first rotating plate 581 and the connecting rod 57 keep rotating in the original position and prevent the support frame 58 from axially shifting.
[0031] A second rotating plate 582 is rotatably connected to the end of the first rotating plate 581 away from the connecting rod 57. The second rotating plate 582 and the first rotating plate 581 cooperate to form a telescopic connecting rod structure. An adjusting rod 59 is inserted at the overlapping part of the first rotating plate 581 and the second rotating plate 582 and rotates with it. The adjusting rod 59 connects the first rotating plate 581 and the second rotating plate 582 and transmits the adjusting force of the positioning block 510. The second rotating plate 582 is rotatably connected to the first rotating plate 581 through the adjusting rod 59. Two sets of third positioning rings 516 are fixedly sleeved on the adjusting rod 59. The third positioning rings 516 limit the axial position of the adjusting rod 59. The two sets of third positioning rings 516 are located on the side away from the first rotating plate 581 and the second rotating plate 582. The third positioning rings 516 ensure that the adjusting rod 59 is always located between the first rotating plate 581 and the second rotating plate 582, preventing it from disengaging and ensuring the structural integrity of the support frame 58.
[0032] A connecting ring 583 is fixedly connected to the end of the second rotating plate 582 away from the first rotating plate 581. The connecting ring 583 enables the second rotating plate 582 to rotate with the rotating tube 51. The connecting ring 583 is rotatably connected to the outer ring of the rotating tube 51. Through the connecting ring 583, one end of the second rotating plate 582 is rotatably connected to the rotating tube 51, forming a complete tilt adjustment linkage mechanism. A positioning block 510 is fixedly connected between the two sets of adjusting rods 59 near the connecting assembly 4. The positioning block 510 provides rotational support for the threaded rod 511. When the positioning block 510 moves, it drives the first rotating plate 581 and the second rotating plate 582 to deflect through the adjusting rods 59, thereby achieving fine adjustment of the length of the support frame 58.
[0033] A threaded rod 511 is rotatably connected to the positioning block 510. The threaded rod 511 converts rotational motion into linear motion, transmitting and adjusting displacement. Two sets of fourth positioning rings 517 are fixedly sleeved on the threaded rod 511, limiting the axial position of the threaded rod 511. The two sets of fourth positioning rings 517 are located on both sides of the positioning block 510, keeping the threaded rod 511 in its original position and preventing axial movement. A threaded sleeve 512 is threadedly connected to the threaded rod 511. The threaded sleeve 512 cooperates with the threaded rod 511 to achieve linear displacement. When the threaded rod 511 rotates, it drives the threaded sleeve 512 to move along the length of the threaded rod 511, pushing the support frame 58 on the other side to deflect. The threaded sleeve 512 is fixedly connected between the other two sets of adjusting rods 59. The threaded sleeve 512 transmits the linear displacement of the threaded rod 511 to the adjusting rods 59. When the threaded sleeve 512 moves, it drives the first rotating plate 581 and the second rotating plate 582 to deflect through the adjusting rods 59, thereby adjusting the tilt angle of the top frame 2 and realizing precise fine-tuning of the down-the-hole drill's drilling angle. A handwheel 513 is installed at the end of the threaded rod 511 away from the positioning block 510. The handwheel 513 increases the operating torque, making it easier to manually rotate the threaded rod 511. The design of the handwheel 513 facilitates the rotation of the threaded rod 511 and reduces the difficulty of operation.
[0034] Finally, the aforementioned support device also includes two sets of support rods 6. The support rods 6 enhance the overall support stability of the device and prevent the device from tipping over. One set of support rods 6 is fixedly connected to the first square tube 11 with multiple sets of connecting seats 61. The connecting seats 61 realize the rigid fixation between the support rods 6 and the square tube. The other set of support rods 6 is fixedly connected to the second square tube 13 through connecting seats 61. The connecting seats 61 ensure the firmness of the connection between the support rods 6 and the square tube. The setting of support rods 6 makes the device stable and adaptable to the support needs of complex construction sites.
[0035] In this embodiment, the operator pushes the second square tube 13 to slide along the length of the first square tube 11, adjusting the length of the second square tube 13 extending beyond the first square tube 11. At this time, the fixing tube 14 simultaneously locks the relative positions of the two sets of second square tubes 13, ensuring the structural stability of the base frame 1 during the extension and retraction process and preventing the rods from shifting. When the required length is reached, the bolt is passed through the first through hole 111 on the first square tube 11 and threaded into the corresponding first threaded hole 131 on the second square tube 13. The cooperation between the first through hole 111 and the first threaded hole 131 forms a rigid lock, fixing the relative position of the second square tube 13 and the first square tube 11, thereby fixing the length of the base frame 1 and preventing extension and retraction displacement during drilling. The connecting tube 12 rigidly connects the two sets of first square tubes 11, always ensuring that the spacing between the two sets of first square tubes 11 is fixed, thus enhancing the lateral stability of the base frame 1.
[0036] The fourth square tube 23 is slid along the third square tube 21 to adjust its extension length to match the telescopic length of the bottom frame 1 and adapt to the working stroke of the down-the-hole drill. The fixing plate 24 strengthens the connection strength of the two sets of fourth square tubes 23 to ensure the structural stability of the top frame 2 during telescopic operation. After adjustment, the bolt is passed through the second through hole 211 on the third square tube 21 and threaded into the corresponding second threaded hole 231 on the fourth square tube 23. The length of the top frame 2 is locked by the cooperation of the second through hole 211 and the second threaded hole 231 to prevent displacement of the top frame 2 during down-the-hole drilling. The connecting plate 22 fixes the two sets of third square tubes 21 into one piece, ensuring a fixed spacing between the two sets of third square tubes 21 and improving the lateral structural strength of the top frame 2.
[0037] The operator can push the mounting plate 31 and slide it along the fourth square tube 23 via the first connecting block 32 to adjust the horizontal working position of the motor 3 and the down-the-hole drill, adapting to different drilling points. The guide plate 33 fixed to the side of the connecting plate 22 provides vertical guidance support for the down-the-hole drill. The guide hole 34 on the guide plate 33 precisely defines the drilling trajectory of the down-the-hole drill. The down-the-hole drill connected to the output end of the motor 3 passes through the guide hole 34 to drill, effectively improving the accuracy of hole positioning and avoiding drilling deviation.
[0038] The height and overall horizontal angle adjustment of one end of the top frame 2 are achieved through the connecting component 4, adapting to drilling requirements of different heights and horizontal directions without the need to rebuild the support structure. The connecting component 4 provides a flexible connection between the bottom frame 1 and the top frame 2. Its two sets of fifth square tubes 41 are fixed to the top of the connecting tube 12, providing vertical sliding guides for the sixth square tube 42. The operator can push the sixth square tube 42 to slide vertically along the fifth square tube 41, adjusting the extension length of the sixth square tube 42, thereby adjusting the height of one end of the top frame 2. The central tube 43 fixes the two sets of sixth square tubes 42 together, ensuring that the two sets of sixth square tubes 42 rise and fall synchronously, ensuring the consistency of the height adjustment of one end of the top frame 2. After adjusting to the required height, the bolt is passed through the third through hole 411 on the fifth square tube 41 and threaded into the corresponding third threaded hole on the sixth square tube 42, locking the relative position of the sixth square tube 42 and the fifth square tube 41, and fixing the height of one end of the top frame 2. The sleeve 44, which is rotatably mounted outside the central tube 43, is located between the two sets of sixth square tubes 42 and remains in place. The two sets of fixing blocks 45 at the top of the sleeve 44 rigidly connect the sleeve 44 to the third square tube 21 of the top frame 2, so that the top frame 2 can rotate with the central tube 43 as the center, thereby driving the motor 3 and the down-the-hole drill to achieve horizontal angle adjustment, adapting to drilling requirements in different horizontal directions, without having to move the entire device, thus improving the convenience of operation.
[0039] The tilt angle of the down-the-hole drill is adjusted by the adjustment mechanism 5 to achieve multi-angle drilling operations, meeting the needs of complex construction scenarios. The adjustment process is precise and smooth. The rotating tube 51 of the adjustment mechanism 5 passes through and is rotatably connected to the two sets of second square tubes 13. The two sets of first positioning rings 514 on the outer ring of the rotating tube 51 are located on opposite sides of the two sets of second square tubes 13, limiting the axial position of the rotating tube 51, ensuring that the rotating tube 51 keeps rotating in place, preventing axial movement, and providing the core rotation fulcrum for the entire adjustment mechanism 5. The two sets of seventh square tubes 52 on the rotating tube 51 provide vertical sliding guides for the eighth square tube 53. The moving plate 54 at the top of the eighth square tube 53 connects the two sets of eighth square tubes 53 into one unit. The L-shaped second connecting blocks 55 at both ends of the moving plate 54 are engaged with the two sets of fourth square tubes 23 on the opposite sides and slide with them, so that the moving plate 54 can slide along the fourth square tube 23, providing length compensation for the tilt adjustment of the top frame 2. Two sets of positioning plates 56 at the bottom of the fixed plate 24 provide rotational support points for the connecting rod 57. The connecting rod 57 connects the two sets of positioning plates 56 and provides an installation base for the support frame 58. The second positioning rings 515 at both ends of the connecting rod 57 limit the axial position of the support frame 58, preventing axial displacement and ensuring stable transmission of adjustment force. The first rotating plate 581 of the support frame 58 is rotatably connected to the connecting rod 57, and the second rotating plate 582 is rotatably connected to the end of the first rotating plate 581 away from the connecting rod 57. The two are rotatably connected by the adjusting rod 59, forming a telescopic linkage structure. Two sets of third positioning rings 516 on the adjusting rod 59 are located on the side away from the first rotating plate 581 and the second rotating plate 582, limiting the axial position of the adjusting rod 59, preventing it from disengaging, and ensuring the structural integrity of the support frame 58. The connecting ring 583 at the end of the second rotating plate 582 away from the first rotating plate 581 is rotatably connected to the outer ring of the rotating tube 51, forming a complete tilt adjustment linkage mechanism. The positioning block 510 between the two sets of adjusting rods 59 near the connecting component 4 provides rotational support for the threaded rod 511. Two sets of fourth positioning rings 517 on the threaded rod 511 are located on both sides of the positioning block 510, limiting the axial position of the threaded rod 511 and ensuring that the threaded rod 511 maintains its original position. The threaded sleeve 512 threadedly connected to the threaded rod 511 is fixed between the other two sets of adjusting rods 59. The operator rotates the handwheel 513 at one end of the threaded rod 511. The handwheel 513 increases the operating torque, reduces the difficulty of operation, and drives the threaded rod 511 to rotate, thereby causing the threaded sleeve 512 to move along the length of the threaded rod 511. When the threaded sleeve 512 moves, it drives the corresponding first rotating plate 581 and second rotating plate 582 to deflect via the adjusting rod 59. Simultaneously, the positioning block 510 synchronously drives the first rotating plate 581 and second rotating plate 582 on the other side to deflect, thereby pushing the top frame 2 to tilt with the central tube 43 of the connecting component 4 as the fulcrum.During this process, the eighth square tube 53 slides along the seventh square tube 52, and the moving plate 54 slides along the fourth square tube 23 through the second connecting block 55 to achieve length compensation when the top frame 2 is tilted, ensuring a smooth adjustment process until the top frame 2 is tilted to the required angle, thereby achieving precise fine-tuning of the down-the-hole drill's drilling angle.
