Description

Technical Field

[0001] The present invention relates to the technical field of drilling equipment, and more particularly to a portable self-impacting tunneling drill experimental device based on intelligent sensing technology. Background Art

[0002] In the field of geotechnical engineering drilling experiments, traditional drilling equipment generally has the problem of insufficient adaptability to complex geological conditions. In particular, when operating in alternating soft and hard rock formations, rigid impact can easily lead to premature failure of the drill bit, and manual replacement of drill rods has defects such as low efficiency and prominent safety hazards. Although the existing technology uses a buffer device to improve the impact problem, it mostly uses a single buffer mechanism and cannot dynamically adjust the buffer stiffness according to the hardness of the rock formation, resulting in insufficient buffering when drilling in soft rock formations and low energy transfer efficiency when drilling in hard rock formations. At the same time, there is a lack of collaborative design with the drill rod automatic switching system, making it difficult to meet the needs of efficient and intelligent experiments. Therefore, it is necessary to provide a portable self-impacting tunneling drill rig experimental device based on intelligent sensing technology to solve the problems raised in the above background technology.

DETAILED DESCRIPTION

[0080] See also Figures 1 to 10 In an embodiment of the present invention, a portable self-impacting tunneling drill experimental device based on intelligent sensing technology includes:

[0081] Pushing mechanism 1, connected to the control box;

[0082] A fixed platform 2 is fixed on the pushing mechanism 1;

[0083] The rubber protective sleeve 3 is provided on the pushing mechanism 1 and is located on both sides of the fixed platform 2;

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

[0085] The fixed component 5 is located on the fixed platform 2 and is fixedly connected to the mobile buffer device 4;

[0086] The drilling rig 6 is fixedly connected to the mobile buffer device 4 through the fixing assembly 5 and is connected to the control box;

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

[0088] The collecting and storing device 8 is arranged on the same side as the drill rod 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 driving motor 12 is fixed to 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, slidably disposed on the slide rail 13;

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

[0095] The shaft sleeve 16 is in the shape of a long tube, one end of which is threadedly connected to the screw 15 , and the top is fixedly connected to the fixed platform 2 , and the other end is fixedly connected to the movable buffer device 4 .

[0096] That is to say, under the action of the control box, the control drive motor 12 drives the screw 15 to rotate, and drives the fixed platform 2 to move on the slide rail 13 through the slider 14 through the sleeve 16, and the mobile 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 drill rod is dynamically buffered and protected by the mobile buffer device 4.

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

[0098] Two movable plates 41 are symmetrically distributed with respect to the moving direction of the pushing mechanism 1, fixedly connected to the fixed assembly 5, and slidably connected to the fixed platform 2;

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

[0100] The fixed 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 fixedly connected to the movable plate 41;

[0102] The high-pressure pipe 45 is connected to one end of the hydraulic buffer assembly 42 close to the fixed plate 43;

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

[0104] That is to say, in the initial state, the low-pressure pipeline 46 is connected to the hydraulic buffer assembly 42. When the drilling rig 6 drills into the soft rock formation, the three-stage spring buffer assembly 44 and the hydraulic buffer assembly 42 perform dynamic buffering adjustment to absorb impact energy and reduce drill bit wear. During the buffering process, the hydraulic buffer assembly 42 is in a small range of dynamic adjustment, so that the low-pressure pipeline 46 is always connected to the hydraulic buffer assembly 42, and cooperates with the three-stage spring buffer assembly 44 to perform dynamic buffering to reduce the impact and vibration of the drill bit, thereby extending the service life of the drill bit; when the drilling rig 6 drills into the hard rock formation, the three-stage spring buffer assembly 44 is subjected to increased pressure, and at the same time, it impacts the hydraulic buffer assembly 42, causing the hydraulic buffer assembly 42 to switch from the low-pressure pipeline 46 to the high-pressure pipeline 45, so that the inside of the hydraulic buffer assembly 42 is in a high-pressure state, thereby fixing the position of the drilling rig 6, so that the impact energy is directly transmitted to the drill bit, improving drilling efficiency, and reducing unnecessary wear of the drill bit.

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

[0106] The connecting tube 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] A hydraulic rod 423, one end of which is slidably disposed in the outer cylinder 422, and the other end of which is slidably connected to the movable plate 41;

[0109] The piston surface 424 is slidably disposed in the outer cylinder 422 and fixedly connected to the hydraulic rod 423;

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

[0111] The reset assembly 426 is fixed in the connecting tube 421 and fixed on the side of the displacement adjustment assembly 425 close to the outer tube 422;

[0112] The conveying connection piece 427 connects the displacement adjustment component 425 and the outer cylinder 422 .

[0113] That is to say, when the drilling rig 6 drills into the soft rock formation, the three-stage spring buffer assembly 44 is compressed to provide a certain buffer, and further drives the hydraulic rod 423 to move in the outer cylinder 422 through the piston surface 424, so that the displacement adjustment assembly 425 is displaced. As the force on the drill bit changes, the displacement adjustment assembly 425 is reset under the action of the reset assembly 426, so that the hydraulic rod 423 is in a dynamic adjustment state, and the low-pressure pipeline 46 is maintained in connection with the displacement adjustment assembly 425. The connecting piece 427 puts the interior of the outer cylinder 422 in a low-pressure state; when the drilling rig 6 drills into the hard rock formation, the pressure on the three-stage spring buffer assembly 44 increases, and at the same time pushes the hydraulic rod 423 to move toward the interior of the outer cylinder 422, pushing the displacement adjustment assembly 425 to adjust, so that the low-pressure pipeline 46 connected to the displacement adjustment assembly 425 is switched to the high-pressure pipeline 45, and the interior of the outer cylinder 422 is put into a high-pressure state through the conveying connecting piece 427, thereby fixing the position of the drilling rig 6, allowing the impact energy to be directly transmitted to the drill bit, and improving the 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 fixedly connected to the movable plate 41;

[0116] The first spring 442 is sleeved on the hydraulic rod 423 and 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 fixedly connected to the second connecting surface 443;

[0119] The third connecting surface 445 is slidably disposed on the outer cylinder 422 and 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] That is to say, when the drilling rig 6 drills into the soft rock formation, the movable plate 41 moves on the fixed platform 2 away from the rock formation under the action of the rock formation pressure. 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 toward the inside of the movable plate 41. As the pressure changes, the second spring 444 is compressed through the second connecting surface 443, and the hydraulic shaft 423 is pushed to move toward the inside of the outer cylinder 422. Dynamic adjustment is performed through the hydraulic buffer assembly 42, and the third connecting surface 445 is slightly driven to move on the outer cylinder 422 to compress the third spring 446. Dynamic buffering is performed through multi-stage spring buffering and hydraulic buffering. The impact adjustment reduces the impact and vibration of the drill bit, thereby extending the service life of the drill bit; when the drilling rig 6 is drilling into a hard rock formation, the drilling rig 6 is subjected to a sudden increase in rock formation pressure, and while compressing the three-stage spring buffer component 44, the displacement adjustment component 425 is triggered, so that the low-pressure pipeline 46 connected to the displacement adjustment component 425 is switched to the high-pressure pipeline 45, and the interior of the outer cylinder 422 is placed in a high-pressure state through the conveying connector 427, thereby fixing the position of the drilling rig 6, so that the impact energy is directly transmitted to the drill bit, thereby improving the drilling efficiency. After stopping drilling, the reset component 426 and the three-stage spring buffer component 44 can be used to drive the displacement adjustment component 425 to reset, and the high-pressure pipeline 45 can be switched 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 passing through the connecting tube 421 and slidingly connected to the fixed plate 43;

[0124] The rotating conveying surface 4252 is rotatably disposed in the connecting cylinder 421 and is threadedly connected to the moving shaft 4251;

[0125] The communication channel 4253 is provided in the rotating conveying surface 4252 and connects the conveying connector 427 with the corresponding high-pressure pipeline 45 and low-pressure pipeline 46 respectively.

[0126] That is to say, when the drilling rig 6 is drilling into a soft rock formation, the hydraulic rod 423 is subjected to a dynamic change in rock formation pressure, and the hydraulic rod 423 pushes the movable shaft 4251 to move toward the fixed plate 43 through the piston surface 424, and at the same time drives the rotating conveying surface 4252 to rotate slightly, so that the connecting channel 4253 is always connected to the low-pressure pipe 46 for dynamic buffering; when the drilling rig 6 is drilling into a hard rock formation, the hydraulic rod 423 is subjected to a sudden increase in rock formation pressure, and the hydraulic rod 423 pushes the movable shaft 4251 to move toward the fixed plate 43 through the piston surface 424, and at the same time drives the rotating conveying surface 4252 to rotate, so that the connecting channel 4253 is always connected to the low-pressure pipe 46 for dynamic buffering. The axial movement of the movable shaft 4251 is converted into the circular motion of the rotating conveying surface 4252, thereby disconnecting the connecting channel 4253 connected to the low-pressure pipeline 46, and connecting the other connecting channel 4253 to the high-pressure pipeline 45. The interior of the outer cylinder 422 is placed in a high-pressure state through the conveying connector 427, thereby fixing the position of the drilling rig 6 and allowing the impact energy to be directly transmitted to the drill bit, thereby improving the drilling efficiency. It should be noted that the connecting thread between the movable shaft 4251 and the rotating conveying surface 4252 can switch back and forth between the linear motion of the movable shaft 4251 and the circular motion of the rotating conveying surface 4252.

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

[0128] Two arc-shaped springs 4261 are symmetrically distributed in the upper and lower parts and are arranged in the connecting tube 421;

[0129] The telescopic arc plates 4262 are provided with two symmetrically distributed around the center, are arranged inside the arc spring 4261, and are fixedly connected to the connecting tube 421;

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

[0131] The movable baffle 4264 is arranged corresponding to 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 protruding end of the telescopic arc plate 4262, and is fixedly connected to the side of the rotating conveying surface 4252.

[0132] That is to say, when the drilling rig 6 is drilling into the hard rock formation, the movable shaft 4251 moves linearly to drive the rotating conveying surface 4252 to perform circular motion. At the same time, the rotating conveying surface 4252 drives the movable baffle 4264 to rotate, compresses the arc spring 4261, and drives the telescopic arc plate 4262 to contract. After the drilling rig 6 stops and leaves the rock formation, the arc spring 4261 rebounds and resets, driving the movable baffle 4264 to reset, and at the same time drives the rotating conveying surface 4252 to rotate and reset, and then switches the high-pressure pipeline 45 back to the low-pressure pipeline 46, and converts the circular motion of the rotating conveying surface 4252 into linear motion of the movable shaft 4251, driving the movable shaft 4251, the piston surface 424 and the hydraulic rod 423 to reset.

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

[0134] The single-axis movable 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] The right-angle column 72 is fixed on the single-axis movable platform 71;

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

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

[0138] The rotating motor 75 is moved outside the fixed arc 74;

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

[0140] The positioning bevel gear 77 is disposed on the inner side of the fixed arc 74 and is fixedly connected to the telescopic shaft 76 .

[0141] That is to say, when the drill rod needs to be switched, the drill rig 6 is stopped, and the fixing clamp 73 is driven by the single-axis mobile platform 71 to move toward the drill chuck at the front end of the drill rig 6. The drill chuck used by the drill 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 74, and the positioning bevel gear 77 is driven to connect with the lock hole through the telescopic shaft 76, and then the positioning bevel gear 77 is driven to rotate by the rotating motor 75, and then the gear ring is driven to rotate to open or lock the wrench-type drill chuck.

[0142] In this embodiment, the collecting and storing device 8 includes:

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

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

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

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

[0147] There are multiple storage slots 85 distributed in an arc shape, which are arranged in the arc-shaped storage body 84 and correspond to the drill rods of the drilling rig 6.

[0148] That is to say, before the drill rod switching device 7 opens the wrench-type drill chuck, the arc-shaped storage body 84 is moved to the position of the drill rod through the two-axis moving platform 81, so that the empty storage slot 85 is placed on the drill rod. After the drill chuck is opened, the removed drill rod is taken back by the storage slot 85, and then the rotating shaft 83 drives the arc-shaped storage body 84 to rotate and replace the drill rod, and the new drill rod is pushed into the drill chuck, locked and fixed by the drill rod switching device 7, and then the collection and storage device 8 is removed.

[0149] During the specific implementation, the pushing mechanism 1 is first fixed in position, and the control box controls the pushing mechanism 1 to drive the drilling rig 6 to conduct a drilling experiment into the rock formation. When drilling into the soft rock formation, 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 in the outer cylinder 422 through the piston surface 424, so that the displacement adjustment assembly 425 produces displacement, that is, the moving shaft 4251 moves toward the fixed plate 43, and at the same time drives the rotating conveying surface 4252 to rotate slightly for dynamic buffering, and as the force at the drill bit changes, the displacement adjustment The component 425 is reset under the action of the reset component 426, so that the hydraulic rod 423 is in a dynamic adjustment state, and the low-pressure pipeline 46 is maintained in connection with the displacement adjustment component 425. The interior of the outer cylinder 422 is in a low-pressure state through the conveying connection 427, and dynamic buffer adjustment is performed to reduce the impact and vibration of the drill bit, thereby extending the service life of the drill bit; when drilling into hard rock formations, the pressure on the three-stage spring buffer component 44 increases suddenly. While compressing the three-stage spring buffer component 44, the hydraulic rod 423 pushes the moving shaft 4251 toward the fixed plate 43 through the piston surface 424, and at the same time drives the rotating conveying surface 4252 to rotate , converting the axial motion of the moving shaft 4251 into the circular motion of the rotating conveying surface 4252. At the same time, the rotating conveying surface 4252 drives the moving baffle 4264 to rotate, compressing the arc spring 4261 and driving the telescopic arc plate 4262 to contract, thereby disconnecting the connecting channel 4253 connected to the low-pressure pipeline 46 and connecting the other connecting channel 4253 to the high-pressure pipeline 45. The interior of the outer cylinder 422 is in a high-pressure state through the conveying connector 427, thereby fixing the position of the drilling rig 6 and directly transmitting the impact energy to the drill bit, thereby improving the drilling efficiency. After the drilling rig 6 stops and leaves the rock formation, the arc spring 4261 rebounds and resets, driving the moving baffle 4264 to rotate, compressing the arc spring 4261 and driving the telescopic arc plate 4262 to contract, thereby disconnecting the connecting channel 4253 connected to the low-pressure pipeline 46 and connecting the other connecting channel 4253 to the high-pressure pipeline 45. The baffle 4264 is reset, and at the same time, the rotating conveying surface 4252 is driven 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 conveying surface 4252 into the linear motion of the moving shaft 4251, driving the moving shaft 4251, the piston surface 424 and the hydraulic rod 423 to reset. When the drill rod needs to be switched, 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, and the new drill rod is pushed into the drill chuck, locked and fixed by the drill rod switching device 7, and then the collection and storage device 8 is removed.
