Description

Technical Field

[0001] This invention relates to the field of drilling equipment technology, and more specifically, to a portable self-impact tunneling drilling rig experimental device based on intelligent sensing technology. Background Technology

[0002] In the field of geotechnical drilling experiments, traditional drilling rigs generally suffer from insufficient adaptability to complex geological conditions. Especially when operating in alternating soft and hard rock formations, rigid impacts can easily lead to premature drill bit failure, and manual drill rod replacement is inefficient and poses significant safety hazards. While existing technologies mitigate impact through buffering devices, they often employ a single buffering mechanism, failing to dynamically adjust buffer stiffness based on rock hardness. This results in insufficient buffering during drilling in soft rock formations and low energy transfer efficiency during drilling in hard rock formations. Furthermore, the lack of coordinated design with automatic drill rod switching systems makes it difficult to meet the demands of efficient and intelligent experiments.

[0080] Please see Figures 1-10 In this embodiment of the invention, a portable self-impacting tunneling drill rig experimental device based on intelligent sensing technology includes:

[0081] Push mechanism 1 connects to the control box;

[0082] Fixed platform 2 is fixed on push mechanism 1;

[0083] Rubber protective sleeves 3 are installed on the pushing mechanism 1 and located on both sides of the fixed platform 2;

[0084] The movable buffer device 4 is slidably connected to the fixed platform 2 and fixedly connected to the pushing mechanism 1;

[0085] Fixed component 5 is located on fixed platform 2 and is fixedly connected to movable buffer device 4;

[0086] The drilling rig 6 is fixedly connected to the movable buffer device 4 via the fixed component 5 and connected to the control box;

[0087] The drill pipe switching device 7 is fixed on one side of the pushing mechanism 1;

[0088] The collection and storage device 8 is located on the same side as the drill pipe switching device 7 and is fixedly connected to the pushing mechanism 1.

[0089] In this embodiment, the pushing mechanism 1 includes:

[0090] Base 11;

[0091] The drive motor 12 is fixed at one end of the base 11 and connected to the control box;

[0092] Two slide rails 13 are symmetrically distributed and fixed on the base 11;

[0093] Slider 14 is slidably mounted on slide rail 13;

[0094] The screw 15 is arranged in the same direction as the slide rail 13, is rotatably mounted on the base 11, and is fixedly connected to the drive motor 12;

[0095] The bushing 16 is a long cylindrical shape. One end is threaded to the screw 15 and the top is fixedly connected to the fixed platform 2. The other end is fixedly connected to the movable buffer device 4.

[0096] In other words, under the control of the control box, the drive motor 12 drives the screw 15 to rotate, and the fixed platform 2 moves on the slide rail 13 via the slider 14 through the bushing 16. The moving buffer device 4 drives the drilling rig 6 to move synchronously through the fixed component 5. When the drilling rig 6 drills into the rock formation, the moving buffer device 4 provides dynamic buffer protection for the drill rod.

[0097] In this embodiment, the moving buffer device 4 includes:

[0098] Two movable plate bodies 41 are symmetrically distributed about the moving direction of the pushing mechanism 1, and are fixedly connected to the fixed component 5 and slidably connected to the fixed platform 2.

[0099] The hydraulic buffer assembly 42 is provided corresponding to the movable plate 41, and one end is slidably connected to the movable plate 41;

[0100] The fixing plate 43 is fixed on the pushing mechanism 1 and is fixedly connected to the other end of the hydraulic buffer assembly 42;

[0101] The three-stage spring buffer assembly 44 is sleeved on the hydraulic buffer assembly 42 and is fixedly connected to the movable plate 41.

[0102] High-pressure pipe 45 is connected to the end of hydraulic buffer assembly 42 near the fixed plate 43;

[0103] The low-pressure pipe 46 is connected to the side opposite to the high-pressure pipe 45 of the hydraulic buffer assembly 42.

[0104] In other words, in the initial state, the low-pressure pipeline 46 is connected to the hydraulic buffer assembly 42. When the drilling rig 6 drills into soft rock formations, the three-stage spring buffer assembly 44 and the hydraulic buffer assembly 42 dynamically buffer and adjust to absorb impact energy and reduce drill bit wear. During the buffering process, the hydraulic buffer assembly 42 is dynamically adjusted within a small range, ensuring that the low-pressure pipeline 46 is always connected to the hydraulic buffer assembly 42. This, combined with the three-stage spring buffer assembly 44, provides dynamic buffering, reducing the impact and vibration on the drill bit and thus extending its service life. When the drilling rig 6 drills into hard rock formations, the pressure on the three-stage spring buffer assembly 44 increases, simultaneously impacting the hydraulic buffer assembly 42. This causes the hydraulic buffer assembly 42 to switch from the low-pressure pipeline 46 to the high-pressure pipeline 45, placing the hydraulic buffer assembly 42 under high pressure. This fixes the position of the drilling rig 6, allowing the impact energy to be directly transmitted to the drill bit, improving drilling efficiency, and reducing unnecessary wear on the drill bit.

[0105] In this embodiment, the hydraulic buffer assembly 42 includes:

[0106] The connecting cylinder 421 is fixedly connected to the side wall of the fixing plate 43;

[0107] The outer cylinder 422 is fixedly connected to the connecting cylinder 421;

[0108] The hydraulic rod 423 has one end slidably disposed inside the outer cylinder 422, and the other end slidably connected to the movable plate 41;

[0109] Piston surface 424 is slidably disposed inside outer cylinder 422 and fixedly connected to hydraulic rod 423;

[0110] The displacement adjustment component 425 is disposed inside the connecting cylinder 421, and one end is fixedly connected to the piston surface 424;

[0111] The reset component 426 is fixed inside the connecting cylinder 421 and fixed on the side of the displacement adjusting component 425 near the outer cylinder 422;

[0112] The conveyor connector 427 connects the displacement adjustment assembly 425 and the outer cylinder 422.

[0113] In other words, when the drilling rig 6 drills into the soft rock layer, the three-stage spring buffer assembly 44 is compressed under pressure, providing a certain buffer, and further driving the hydraulic rod 423 to move within the outer cylinder 422 through the piston surface 424, causing the displacement adjustment assembly 425 to move. As the force at the drill bit changes, the displacement adjustment assembly 425 is reset under the action of the reset assembly 426, keeping the hydraulic rod 423 in a dynamic adjustment state, and maintaining the connection between the low-pressure pipeline 46 and the displacement adjustment assembly 425, through the conveyor... The connector 427 keeps the interior of the outer cylinder 422 under low pressure. When the drill rig 6 drills into hard rock formations, the pressure on the three-stage spring buffer assembly 44 increases, which in turn pushes the hydraulic rod 423 to move into the interior of the outer cylinder 422. This pushes the displacement adjustment assembly 425 to adjust, switching the low-pressure pipeline 46 connected to the displacement adjustment assembly 425 to the high-pressure pipeline 45. Through the conveying connector 427, the interior of the outer cylinder 422 is kept under high pressure, thereby fixing the position of the drill rig 6 and allowing the impact energy to be directly transmitted to the drill bit, thus improving drilling efficiency.

[0114] In this embodiment, the three-stage spring buffer assembly 44 includes:

[0115] The first connecting surface 441 is slidably disposed on the hydraulic rod 423 and is fixedly connected to the movable plate 41;

[0116] The first spring 442 is sleeved on the hydraulic rod 423 and is fixedly connected to the first connecting surface 441;

[0117] The second connecting surface 443 is fixed on the hydraulic rod 423 and is fixedly connected to the first spring 442;

[0118] The second spring 444 is sleeved on the hydraulic rod 423 and the outer cylinder 422 and is fixedly connected to the second connecting surface 443.

[0119] The third connecting surface 445 is slidably disposed on the outer cylinder 422 and is fixedly connected to the second spring 444;

[0120] The third spring 446 is sleeved on the outer cylinder 422, and its two ends are fixedly connected to the connecting cylinder 421 and the third connecting surface 445.

[0121] In other words, when the drilling rig 6 drills into the soft rock layer, under the pressure of the rock layer, the moving plate 41 moves away from the rock layer on the fixed platform 2. At the same time, under the action of the first connecting surface 441, the first spring 442 is compressed, and the hydraulic rod 423 moves into the moving plate 41. As the pressure changes, while the second spring 444 is compressed through the second connecting surface 443, the hydraulic shaft 423 is pushed into the outer cylinder 422. Dynamic adjustment is achieved through the hydraulic buffer assembly 42, and the third connecting surface 445 is slightly moved on the outer cylinder 422, compressing the third spring 446. Through multi-stage spring buffering and hydraulic buffering, dynamic buffering is achieved. The impact adjustment reduces the impact and vibration on the drill bit, thereby extending its service life. When the drill rig 6 drills into hard rock formations, the drill rig 6 experiences a sudden increase in rock pressure. This compresses the three-stage spring buffer assembly 44 and triggers the displacement adjustment assembly 425, causing the low-pressure pipeline 46 connected to the displacement adjustment assembly 425 to switch to the high-pressure pipeline 45. Through the conveying connector 427, the inner part of the outer cylinder 422 is kept under high pressure, thereby fixing the position of the drill rig 6 and allowing the impact energy to be directly transmitted to the drill bit, improving drilling efficiency. After drilling stops, the displacement adjustment assembly 425 can be reset by the reset assembly 426 and the three-stage spring buffer assembly 44, switching the high-pressure pipeline 45 back to the low-pressure pipeline 46.

[0122] In this embodiment, the displacement adjustment component 425 includes:

[0123] The movable shaft 4251 has one end fixedly connected to the piston surface 424, and the other end passes through the connecting cylinder 421 and is slidably connected to the fixed plate 43;

[0124] The rotating conveyor surface 4252 is rotatably disposed inside the connecting cylinder 421 and threadedly connected to the moving shaft 4251.

[0125] The connecting channel 4253 is set inside the rotating conveying surface 4252, and connects the conveying connector 427 to the corresponding high-pressure pipe 45 and low-pressure pipe 46 respectively.

[0126] In other words, when drilling rig 6 drills into soft rock formations, the hydraulic rod 423 experiences dynamic changes in rock pressure. The hydraulic rod 423, through piston surface 424, pushes the moving shaft 4251 towards the fixed plate 43, simultaneously causing the rotating conveying surface 4252 to rotate slightly, ensuring the connecting channel 4253 remains connected to the low-pressure pipeline 46 for dynamic buffering. When drilling rig 6 drills into hard rock formations, the hydraulic rod 423 experiences a sudden increase in rock pressure. The hydraulic rod 423, through piston surface 424, pushes the moving shaft 4251 towards the fixed plate 43, simultaneously causing the rotating conveying surface 4252 to rotate, thus shifting the moving shaft 4251 towards the fixed plate 43. The axial movement of the moving shaft 4251 is converted into the circumferential movement of the rotating conveying surface 4252, thereby disconnecting the connecting channel 4253 connected to the low-pressure pipeline 46 and connecting another connecting channel 4253 to the high-pressure pipeline 45. The conveying connector 427 keeps the inside of the outer cylinder 422 under high pressure, thereby fixing the position of the drilling rig 6 and allowing the impact energy to be directly transmitted to the drill bit, improving drilling efficiency. It should be noted that the connecting thread between the moving shaft 4251 and the rotating conveying surface 4252 allows the linear movement of the moving shaft 4251 and the circumferential movement of the rotating conveying surface 4252 to switch back and forth.

[0127] In this embodiment, the reset component 426 includes:

[0128] Two arc-shaped springs 4261 are symmetrically distributed vertically and are installed inside the connecting cylinder 421;

[0129] Two telescopic arc plates 4262 are centrally symmetrically distributed and are located inside the arc spring 4261, and are fixedly connected to the connecting cylinder 421.

[0130] Two fixed baffles 4263 are centrally symmetrically distributed and are respectively fixedly connected to the fixed end of the telescopic arc plate 4262 and the arc spring 4261;

[0131] The movable baffle 4264 is set in correspondence with the fixed baffle 4263, is fixedly connected to the end of the arc spring 4261 away from the fixed baffle 4263, is fixedly connected to the extended end of the telescopic arc plate 4262, and is fixedly connected to the side of the rotating conveying surface 4252.

[0132] In other words, when the drilling rig 6 drills into hard rock formations, the linear movement of the moving shaft 4251 drives the rotating conveying surface 4252 to perform circular motion. At the same time, the rotating conveying surface 4252 drives the moving baffle 4264 to rotate, compressing the arc spring 4261 and causing the telescopic arc plate 4262 to retract. After the drilling rig 6 stops and disengages from the rock formation, the arc spring 4261 rebounds and resets, driving the moving baffle 4264 to reset. Simultaneously, the rotating conveying surface 4252 rotates and resets, thereby switching the high-pressure pipeline 45 back to the low-pressure pipeline 46. The circular motion of the rotating conveying surface 4252 is converted into the linear motion of the moving shaft 4251, causing the moving shaft 4251, piston surface 424, and hydraulic rod 423 to reset.

[0133] In this embodiment, the drill pipe switching device 7 includes:

[0134] A single-axis moving platform 71 is fixed to the side of the pushing mechanism 1, and its moving direction is perpendicular to the moving direction of the pushing mechanism 1.

[0135] A right-angle column 72 is fixed on a single-axis moving platform 71;

[0136] The fixing clamp 73 is fixed on the right-angle column 72 and corresponds to the drill chuck on the drilling rig 6;

[0137] The fixed arc 74 is fixed to the side of the right-angle column 72;

[0138] Rotate motor 75 to move it to the outside of fixed arc track 74;

[0139] The telescopic shaft 76 passes through the fixed arc track 74 and is fixedly connected to the rotating motor 75;

[0140] The positioning bevel gear 77 is located inside the fixed arc track 74 and is fixedly connected to the telescopic shaft 76.

[0141] In other words, when it is necessary to switch the drill rod, the drilling rig 6 stops, and the single-axis moving platform 71 drives the fixed clamp 73 to move towards the drill chuck at the front end of the drilling rig 6. The drill chuck used by the drilling rig 6 here is a wrench-type drill chuck. The wrench-type drill chuck is fixed, and then the rotating motor 75 moves on the fixed arc track 74. The telescopic shaft 76 drives the positioning bevel gear 77 to connect with the locking hole. Then, the rotating motor 75 drives the positioning bevel gear 77 to rotate, which in turn drives the gear ring to rotate, thus opening or locking the wrench-type drill chuck.

[0142] In this embodiment, the collection and storage device 8 includes:

[0143] The two-axis moving platform 81 is fixed to the side of the pushing mechanism 1;

[0144] The lifting column 82 has a right angle at the top and is fixed on the two-axis moving platform 81;

[0145] The rotating shaft 83 is rotatably mounted on the lifting column 82;

[0146] The arc-shaped storage body 84 is fixed at its center on the rotating shaft 83;

[0147] Storage slots 85 are provided in multiple arc-shaped configurations and are located within arc-shaped storage bodies 84, corresponding to the drill rods of drilling rig 6.

[0148] In other words, before the drill pipe switching device 7 opens the wrench-type drill chuck, the arc-shaped storage body 84 is moved to the position of the drill pipe by the two-axis moving platform 81, so that the empty storage slot 85 is fitted onto the drill pipe. After the drill chuck is opened, the removed drill pipe is retrieved by the storage slot 85. Then, the rotating shaft 83 drives the arc-shaped storage body 84 to rotate and replace the drill pipe, pushing the new drill pipe into the drill chuck. The drill pipe switching device 7 locks and fixes it, and then the collection and storage device 8 is removed.

[0149] In practice, the position of the pushing mechanism 1 is first fixed. The control box controls the pushing mechanism 1 to drive the drilling rig 6 to drill into the rock formation. When drilling into soft rock formations, the three-stage spring buffer assembly 44 and the hydraulic buffer assembly 42 perform dynamic buffering adjustment. The three-stage spring buffer assembly 44 is compressed under pressure to provide a certain buffer, and further drives the hydraulic rod 423 to move through the piston surface 424 within the outer cylinder 422, causing the displacement adjustment assembly 425 to move, that is, the moving shaft 4251 moves towards the fixed plate 43, while simultaneously causing the rotating conveying surface 4252 to rotate slightly for dynamic buffering. The displacement adjustment also changes with the force at the drill bit. Component 425 is reset under the action of reset component 426, so that hydraulic rod 423 is in a dynamic adjustment state, and the low-pressure pipeline 46 is maintained connected to displacement adjustment component 425. Through the conveying connector 427, the inside of outer cylinder 422 is kept in a low-pressure state for dynamic buffer adjustment, reducing the impact and vibration on the drill bit, thereby extending the service life of the drill bit. When drilling hard rock formations, the pressure on the three-stage spring buffer component 44 increases sharply. While compressing the three-stage spring buffer component 44, hydraulic rod 423 pushes moving shaft 4251 towards fixed plate 43 through piston surface 424, and at the same time drives rotating conveying surface 4252 to rotate. The axial motion of the moving shaft 4251 is converted into the circular motion of the rotating conveying surface 4252. Simultaneously, the rotating conveying surface 4252 drives the moving baffle 4264 to rotate, compressing the arc spring 4261 and causing the telescopic arc plate 4262 to retract. This disconnects the connecting channel 4253 connected to the low-pressure pipeline 46 and connects another connecting channel 4253 to the high-pressure pipeline 45. Through the conveying connector 427, the interior of the outer cylinder 422 is kept under high pressure, thus fixing the position of the drilling rig 6 and allowing the impact energy to be directly transmitted to the drill bit, improving drilling efficiency. After the drilling rig 6 stops and detaches from the rock strata, the arc spring 4261 rebounds and resets, driving the moving baffle 4264 to rotate. The baffle 4264 resets, simultaneously driving the rotating conveyor surface 4252 to rotate and reset, thereby switching the high-pressure pipeline 45 back to the low-pressure pipeline 46, and converting the circular motion of the rotating conveyor surface 4252 into the linear motion of the moving shaft 4251, driving the moving shaft 4251, piston surface 424, and hydraulic rod 423 to reset. When it is necessary to switch the drill rod, the plate drill chuck is opened through the drill rod switching device 7, and the removed drill rod is retrieved by the storage slot 85. Then, the rotating shaft 83 drives the arc-shaped storage body 84 to rotate and replace the drill rod, pushing the new drill rod into the drill chuck, which is then locked and fixed by the drill rod switching device 7. Finally, the collection and storage device 8 is removed.
