Description

Technical Field

[0001] The present invention relates to the technical field of deep well drilling rig tests, and particularly to a high-precision deep well drilling rig test bench and a test method. Background Technique

[0002] A deep well drilling rig is a mechanical device used for drilling deep wells, which is widely used in fields such as oil and gas exploration, geothermal development, mineral resource extraction, and scientific research. It drives the drill bit to rotate or impact through mechanical power to achieve the drilling of materials such as rocks and soils.

[0003] During the drilling process, the drill pipe needs to withstand a large torque. Therefore, before using the drill pipe, it is necessary to detect its torque. Detecting the torque can ensure that the drill pipe will not be damaged due to overload during use, thus ensuring the safety and reliability of the equipment.

[0004] Usually, to detect the torque of the drill pipe, the drill pipe of the deep well drilling rig is connected to the rotating end of the torque detection device, and a force sensor is installed on the lower side of the rotating end to detect the force acting on the lower part of the drill pipe. Finally, the torque of this drill pipe is obtained by multiplying the force under the drill pipe by the distance from the drill pipe to the rotation center. However, this torque detection can only detect the torque of the drill pipe without interference from other environmental factors. Even if there are difficult-to-observe tiny cracks, pores, inclusions and other defects on the surface of the drill pipe, these defects will not affect its torque during the idle rotation of the drill pipe and are difficult to be discovered. But when the drill pipe rotates surrounded by particles of different materials, the particles will fill into these cracks and pores. The particle filling will change the density and mass distribution of the drill pipe, making it uneven. This unevenness will cause an unbalanced centrifugal force when the drill pipe rotates, thereby increasing the torque of the drill pipe. When the torque received by the drill pipe exceeds its yield strength, plastic deformation will occur. The plastic deformation will change the stress distribution of the drill pipe, generate new stress concentration points, and accelerate the initiation and propagation of fatigue cracks.

[0005] Therefore, it is very necessary to design a high-precision deep well drilling rig test bench that can simulate the environment around the drill pipe for torque detection. Summary of the Invention

[0017] A test method for a high-precision deep well drilling rig test bench. According to the above-mentioned high-precision deep well drilling rig test bench, it includes the following steps:

[0018] S1: The deep well drilling rig sequentially passes the drill pipe through the compaction mechanism and the environmental simulation mechanism, inserts it into the inside of the clamping mechanism, and drives the drill pipe to rotate.

[0019] S2: The detection mechanism initially detects the torque of the drill pipe and judges whether the torque of the drill pipe is within the normal range.

[0020] S3: When the torque of the drill pipe is within the normal range, the blanking mechanism conveys different materials above the conveying mechanism into the inside of the environmental simulation mechanism respectively, and the compaction mechanism compacts each material respectively.

[0021] S4: The detection mechanism respectively detects the torque generated by the rotation of the drill pipe when the drill pipe is surrounded by different materials, and judges again whether the torque of the drill pipe is within the normal range.

[0022] S5: Each time the feeding and discharging of the material are automatic, and while discharging the material, the material inside the environmental simulation mechanism is driven to move.

[0023] S6: After the detection of the drill pipe is completed, the clamping mechanism is opened to take out the drill pipe and then closed. When the clamping mechanism is closed, the dirt at the clamping end is indirectly cleaned.

[0024] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0025] 1. When detecting the torque of the drill pipe, by covering different materials on the surface of the drill pipe respectively, the environment around the drill pipe during drilling is simulated, the torque of the drill pipe is detected in real time, and according to the magnitude of the torque of the drill pipe, it is judged whether there are defects on the surface of the drill pipe, effectively preventing the torque of the drill pipe from changing due to surface defects during idling of the drill pipe, making it difficult to detect surface defects of the drill pipe, and causing the phenomenon of abnormal torque of the drill pipe during actual drilling, achieving the effect of high accuracy in detecting torque.

[0026] 2. While the discharge chute is open, the electric button is powered on, driving the first gear to engage with the second gear and the third gear respectively, thereby driving the scraping bar to rotate when the material is discharged. When the scraping bar rotates, it can not only break up the compacted material, but also push the last remaining material pile towards the discharge chute, accelerating the discharge speed of the material and improving the detection efficiency of the torque of the rotating rod. While the discharge chute is closed, the electric button is powered off, and the first gear no longer engages with the second gear and the third gear, and the scraping bar no longer rotates, effectively preventing the rotation of the scraping bar from affecting the compaction of the material when the torque of the subsequent drill rod is detected, achieving the effect of adaptive discharging.

[0027] 3. The first motor drives the turntable to rotate, causing each clamping block to move along the straight chute and the hexagonal chute, thereby clamping the drill rod. When the drill rod is not clamped, by closing the six clamping blocks, the sharp corner of the previous clamping block shovels the material on the clamping surface of the next clamping block, and then shovels the dirt on the clamping surface of each clamping block into the storage tank, effectively preventing the phenomenon that excessive dirt accumulates and adheres to the clamping end after too many detections, achieving the effect of automatically cleaning the dirt on the clamping surface.

[0046] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0047] Embodiment 1: Please refer to Figures 1-10 , the present invention provides a technical solution: a high-precision deep well drill rig test bench, including a base 1, a transmission mechanism 2 is provided on the upper side of the base 1, a detection mechanism 3 for torque detection of the drill pipe is provided on one side of the transmission mechanism 2, a clamping mechanism 4 for clamping and fixing the drill pipe is provided on the upper side of the detection mechanism 3, an environmental simulation mechanism 5 for simulating the environment around the drill pipe is provided on the upper side of the clamping mechanism 4, a compaction mechanism 6 for compacting the filled material is provided on the upper side of the environmental simulation mechanism 5, a conveying mechanism 8 for conveying different types of materials is provided on one side of the detection mechanism 3, and a material pouring mechanism 7 for pouring the material into the environmental simulation mechanism 5 is provided on one side of the conveying mechanism 8.

[0048] Please refer to Figure 2 , the detection mechanism 3 includes a support seat 36 fixedly connected to the upper side of the base 1, a force receiving sleeve 37 is fixedly connected inside the support seat 36, a force sensor 38 is provided below the force receiving sleeve 37, a key shaft 34 is rotatably connected to the upper side of the force receiving sleeve 37, a key sleeve 33 is fixedly connected to the outside of the key shaft 34, the key sleeve 33 is rotatably connected to the support seat 36, a large gear 35 is fixedly connected to the outside of the key sleeve 33, a small gear 31 is meshed and connected to one side of the large gear 35, and a connecting shaft 32 is fixedly connected inside the small gear 31.

[0049] Specifically, when the key shaft 34 is driven to rotate, the key sleeve 33 is driven to rotate, and the large gear 35 is indirectly driven to rotate, thereby driving the small gear 31 to rotate. When the key shaft 34 rotates, a force is generated below to press the force receiving sleeve 37, and the force sensor 38 detects the pressure, thereby calculating the torque of the upper drill pipe.

[0050] Please refer to Figure 2, the transmission mechanism 2 includes a second gearbox 29 provided on the lower side of the connecting shaft 32. One end of the connecting shaft 32 is fixedly connected to the input end of the second gearbox 29. A universal coupling 28 is fixedly connected to the output end of the second gearbox 29. The other end of the universal coupling 28 penetrates through the bearing seat 27 and is fixedly connected to a torque limiter 26. The other end of the torque limiter 26 is fixedly connected to a torque loader 25. The other end of the torque loader 25 is fixedly connected to a diaphragm coupling 24. A first gearbox 23 is provided on one side of the diaphragm coupling 24. The input end of the first gearbox 23 is fixedly connected to the other end of the diaphragm coupling 24 and the output end is fixedly connected to a clutch 22. A dynamometer 21 is fixedly connected to the upper side of the base 1 and the input end is fixedly connected to the other end of the clutch 22.

[0051] Specifically, the connecting shaft 32 is driven by the pinion 31 to rotate. While rotating, it indirectly drives the universal coupling 28 to rotate through the second gearbox 29. When passing through the torque limiter 26, the torque limiter 26 can monitor and limit the torque in real time. When the torque exceeds the set value, it will automatically cut off the energy or issue an alarm, thereby preventing the equipment and machines from being damaged due to overload. When passing through the torque loader 25, the torque loader 25 can accurately measure the applied torque value through the built-in torque sensor, ensuring the accuracy of the test. The connection of the diaphragm coupling 24 enables the universal coupling 28 to bear a large torque. Through the elastic deformation of the diaphragm, vibration and noise are reduced, which is suitable for high-load transmission systems. Then, through the transmission of the first gearbox 23, the power is transmitted to the input end of the dynamometer 21, and the dynamometer 21 measures the output power of the drill pipe by absorbing and consuming.

[0052] Please refer to Figure 5 , the environment simulation mechanism 5 includes two second L-shaped blocks 51 fixedly connected to the upper side of the base 1. A simulation barrel 52 is fixedly connected between the two second L-shaped blocks 51. A blanking plate 53 is fixedly connected to the upper side of the simulation barrel 52 and a discharging plate 54 is fixedly connected to the lower side. A cleaning component 55 is provided below the simulation barrel 52. A discharging component 56 is provided on one side of the discharging plate 54.

[0053] Specifically, the height of the simulation barrel 52 can change with the length of the drill pipe. Different materials are placed inside the simulation barrel 52 to surround the drill pipe, so that when the drill pipe rotates, different rotation environments are simulated, and then the torque of the drill pipe in each different environment is obtained, magnifying the defects of the drill pipe and making them easier to be discovered. The blanking plate 53 is used to make the material flow into the simulation barrel 52 more easily, and the discharging plate 54 is used to reflow the material inside the simulation barrel 52 into the previous tank.

[0054] A guide slider 61 is fixedly connected to the upper side of each second L-shaped block 51. A first cylinder 63 is provided on one side of each guide slider 61 and the first cylinder 63 is fixedly connected to the second L-shaped block 51. The output end of the guide slider 61 is fixedly connected to a first L-shaped block 62 and the first L-shaped block 62 is slidably connected to the guide slider 61. The other end of the first L-shaped block 62 is fixedly connected to a pressure plate 64, and an avoidance hole is provided in the middle of the pressure plate 64.

[0055] Specifically, when the inside of the simulation barrel 52 is filled with materials, the output end of the first cylinder 63 retracts to drive the pressure plate 64 to move downward, thereby compacting the loose materials and making the environment simulation more accurate.

[0056] Please refer to Figure 6 , the conveying mechanism 8 includes a conveyor 81 fixedly connected to the upper side of the base 1. The conveying ends of the conveyor 81 are respectively provided with a soil tank 82, a rock tank 83 and a sand tank 84. The soil tank 82, the rock tank 83 and the sand tank 84 have the same structure. The soil tank 82 includes a chuck 824 fixedly connected to the conveying end of the conveyor 81. A tank body 822 is provided inside the chuck 824. A clamping block 823 is fixedly connected to the outer side of the tank body 822 and is slidably connected to the inner wall of the chuck 824. A fixing column 821 is fixedly connected to the upper side of the tank body 822.

[0057] Specifically, the soil tank 82 is used to store soil particles, the rock tank 83 is used to store rock particles, and the sand tank 84 is used to store sand particles. These three materials are common shaft wall materials. The conveying end of the conveyor 81 is used to convey the soil tank 82, the rock tank 83 and the sand tank 84 in sequence, thereby driving the soil tank 82, the rock tank 83 and the sand tank 84 to move left and right.

[0058] Please refer to Figures 7-9 , a discharge chute is provided on the lower side of the simulation barrel 52. The discharge assembly 56 includes a first baffle 562 fixedly connected to the inside of the discharge chute. A second baffle 565 is slidably connected to the inner wall of the first baffle 562. Bent springs 561 are provided inside both the second baffle 565 and the first baffle 562. One end of the bent spring 561 is fixedly connected to the discharge chute and the other end is fixedly connected to the second baffle 565. The other end of the second baffle 565 is fixedly connected to a pressing block 564. The pressing block 564 is slidably connected to the simulation barrel 52. An electric button 563 is pressed against one side of the pressing block 564. The electric button 563 is fixedly connected to the simulation barrel 52. A connecting rod 566 is fixedly connected to one side of the second baffle 565. The other end of the connecting rod 566 is hinged to a blocking rod 567. A limiting plate 568 is provided on one side of the blocking rod 567 and the limiting plate 568 is fixedly connected to the connecting rod 566.

[0059] Specifically, when the bending spring 561 is fully extended, the material is blocked by the second baffle 565 and the first baffle 562 and cannot pass through the discharge chute. When the bending spring 561 is fully retracted, the second baffle 565 retracts into the first baffle 562, and at this time the discharge chute is opened, and the material can pass through the discharge chute.

[0060] When the tank body 822 is driven to move leftward, the stop lever 567 is struck by the fixed column 821 above the tank body 822. At this time, the contact end of the stop lever 567 presses against the left quadrant point of the fixed column 821, and the stop lever 567 is driven to move leftward by the fixed column 821. The second baffle 565 is driven to slide along the inner wall of the first baffle 562, and the bending spring 561 is gradually compressed. Since both the second baffle 565 and the first baffle 562 are arc-shaped plates, the stop lever 567 also moves in an arc when moving until the tank body 822 moves to the lower part of the discharge end of the discharge plate 54. The conveyor 81 stops driving the tank body 822 to move. At this time, the material inside the simulation barrel 52 can flow into the tank body 822. When one of the tank bodies 822 is filled with material, the conveyor 81 drives the filled tank body 822 to continue moving leftward. At this time, the contact end of the stop lever 567 presses against the upper quadrant point of the fixed column 821 until the fixed column 821 is displaced to the left of the stop lever 567. At this time, the stop lever 567 is no longer pressed, and the bending spring 561 extends to drive the stop lever 567 and the second baffle 565 to return to their positions.

[0061] When the materials in the three tank bodies 822 have all been detected for the drill rod torque, at this time the three tank bodies 822 are located on the left side of the discharge plate 54. The conveyor 81 drives the three tank bodies 822 to move rightward to return to their positions. Since the stop lever 567 is hinged to the connecting rod 566, when returning to the position, the fixed column 821 drives the stop lever 567 to rotate without causing interference. Since a limit plate 568 is provided on one side of the stop lever 567, when the three tank bodies 822 move leftward, the fixed column 821 strikes the stop lever 567, and the stop lever 567 will not be driven to rotate.

[0062] Please refer to Figure 10 As shown in, the pouring mechanism 7 includes two positioning plates 71 fixedly connected to the upper side of the base 1. A second hydraulic cylinder 76 is provided between the two positioning plates 71. The output end of the second hydraulic cylinder 76 is fixedly connected with a moving block 74, and the moving block 74 is slidably connected with the positioning plate 71. The upper side of the moving block 74 is fixedly connected with a first hydraulic cylinder 72. The output end of the first hydraulic cylinder 72 is fixedly connected with a fixed block 75. A double-shaft hydraulic cylinder 73 is fixedly connected to the upper side of the fixed block 75. Both output ends of the double-shaft hydraulic cylinder 73 are fixedly connected with sliding plates 77. One side of the sliding plate 77 is fixedly connected with a second motor 78. The output end of the second motor 78 penetrates through the sliding plate 77 and is fixedly connected with a clamping plate 79.

[0063] Specifically, the extension of the output end of the first hydraulic cylinder 72 is used to drive the clamping plate 79 to move, so that the tank body 822 is located between the two clamping plates 79. The retraction of the output end of the double-shaft hydraulic cylinder 73 is used to drive the clamping plates 79 to approach each other, thereby clamping the tank body 822. The extension of the output end of the second hydraulic cylinder 76 is used to drive the tank body 822 to move upward, thereby bringing the tank body 822 above the pouring plate 53. The rotation of the output end of the second motor 78 is used to drive the tank body 822 to flip, so that the materials inside the tank body 822 are poured into the pouring plate 53 and then flow into the simulation barrel 52.

[0064] When excessive torque is detected, it is determined that there are defects such as tiny cracks, pores, and inclusions on the surface of the drill pipe that are difficult to observe. Because the particles will fill into these cracks and pores, the particle filling will change the density and mass distribution of the drill pipe, making it uneven. This unevenness will cause an unbalanced centrifugal force to be generated when the drill pipe rotates, thereby increasing the torque of the drill pipe.

[0065] When too little torque is detected, it is determined that the drill pipe is corroded or mechanically damaged, resulting in pits or spiral grooves on the surface of the drill pipe. The grooves may change the mud flow path, form local eddies or lubricating films, and reduce the viscous resistance, thereby reducing the torque of the drill pipe.

[0066] When detecting the torque of the drill pipe, different materials are respectively covered on the surface of the drill pipe to simulate the surrounding environment of the drill pipe during drilling, and the torque of the drill pipe is detected in real time. Then, according to the magnitude of the drill pipe torque, it is judged whether there are defects on the surface of the drill pipe, effectively preventing the torque of the drill pipe from changing due to surface defects during idling. The surface defects of the drill pipe are difficult to be found, resulting in abnormal torque of the drill pipe during actual drilling, achieving the effect of high accuracy in detecting torque.

[0067] Embodiment 2: Since the materials inside the simulation barrel 52 are all compacted and the flow rate is slow, when discharging, the materials inside the simulation barrel 52 are difficult to be discharged, and most of the materials are prone to accumulate inside the simulation barrel 52, resulting in an increase in the material discharge time, an increase in the detection time of the drill pipe torque, and a reduction in the detection efficiency of the drill pipe torque. Therefore, the following structure is designed to solve the above technical problems.

[0068] Please refer to Figure 7, the cleaning component 55 includes a second gear 554 fixedly connected to the upper side of the connecting shaft 32. A second cylinder 551 is fixedly connected to the lower side of the simulation barrel 52. The output end of the second cylinder 551 is fixedly connected with a sliding block 552, and the sliding block 552 is slidably connected to the lower side of the simulation barrel 52. The lower side of the sliding block 552 is connected to a first gear 553 by a bearing. A rotating ring 555 is rotatably connected to the middle of the simulation barrel 52. A rotating hole is provided in the middle of the rotating ring 555. A scraping strip 556 is fixedly connected to the outer side of the rotating ring 555. A third gear 557 is fixedly connected to the lower side of the rotating ring 555.

[0069] Specifically, when the electric button 563 is pressed, the power is cut off, and when it is released, the power is turned on. When the discharge chute is closed, the electric button 563 is pressed by the pressing block 564. At this time, the second cylinder 551 is in a fully extended state, and the first gear 553 cannot mesh with the second gear 554 and the third gear 557, and the scraping strip 556 cannot be driven to rotate.

[0070] When the discharge chute is opened, the materials inside the simulation barrel 52 start to flow outwards. At this time, the electric button 563 is no longer pressed by the pressing block 564. The electric button 563 sends a signal to the second cylinder 551. The output end of the second cylinder 551 starts to retract, driving the first gear 553 to mesh with the second gear 554 and the third gear 557 respectively. At this time, the second gear 554 drives the first gear 553 to rotate, thereby driving the third gear 557 to rotate, and further driving the scraping strip 556 to rotate. While the scraping strip 556 rotates, it can not only disperse the compacted materials, but also push the last remaining materials towards the discharge chute, accelerating the discharge speed of the materials and improving the detection efficiency of the torque of the rotating rod.

[0071] When the discharge chute is opened, the electric button 563 is powered on, driving the first gear 553 to mesh with the second gear 554 and the third gear 557 respectively, thereby driving the scraping strip 556 to rotate when the materials are discharged. While the scraping strip 556 rotates, it can not only disperse the compacted materials, but also push the last remaining materials towards the discharge chute, accelerating the discharge speed of the materials and improving the detection efficiency of the torque of the rotating rod. When the discharge chute is closed, the electric button 563 is powered off, and the first gear 553 no longer meshes with the second gear 554 and the third gear 557, and the scraping strip 556 no longer rotates, effectively preventing the scraping strip 556 from rotating and affecting the compaction of the materials when the torque of the subsequent drill pipe is detected, achieving the effect of adaptive discharging.

[0072] Embodiment 3: For a small number of drill pipes under frequent use or high load conditions, it is necessary to disassemble them in time to detect their torque, so as to evaluate the fatigue strength of the drill pipes. The greater the torque, the greater the stress generated, thus accelerating the fatigue damage of the drill pipes. Since the surface of the frequently used drill pipes will be contaminated with some drilling fluid, mud and other dirt, when clamping the drill pipes, a small amount of dirt on the surface will adhere to the clamping end. After too many detections, too much dirt will accumulate and adhere to the clamping end. The presence of dirt will cause uneven distribution of the clamping force, resulting in excessive local stress on the drill pipe during clamping, and then causing bending deformation of the drill pipe. The bending deformation may change the contact state between the drill pipe and the sensor, increase the measurement error of the sensor, and reduce the accuracy of torque detection. Therefore, the following structure is designed to solve the above technical problems.

[0073] Please refer to Figure 3 and Figure 4 , the clamping mechanism 4 includes a first motor 41 fixedly connected to the inside of the upper end of the key shaft 34. A rotating cylinder 42 is fixedly connected to the upper side of the key shaft 34. The output end of the first motor 41 penetrates through the rotating cylinder 42 and is fixedly connected to a turntable 43. A material storage groove 44 and a hexagonal chute 45 are respectively arranged inside the turntable 43. The turntable 43 is rotationally connected to the inner wall of the rotating cylinder 42. A plurality of clamping blocks 47 are evenly slidably connected to the inside of the hexagonal chute 45. A cylinder 46 is fixedly connected to the upper side of each clamping block 47. A circular ring 49 is arranged on the upper side of the clamping block 47. A plurality of guide sliding plates 48 are evenly and fixedly connected to the outer side of the circular ring 49. The other side of each guide sliding plate 48 is fixedly connected to the inner wall of the rotating cylinder 42. A straight chute is arranged inside each guide sliding plate 48. The cylinder 46 is slidably connected to the straight chute.

[0074] Specifically, in the initial state, the clamping mechanism 4 is in an open state. When it is necessary to clamp the drill pipe, the output end of the first motor 41 rotates counterclockwise, driving the turntable 43 to rotate counterclockwise, and then driving the clamping blocks 47 to slide along the hexagonal chute 45, and the cylinder 46 slides along the straight chute. At this time, one side clamping surfaces of the six clamping blocks 47 clamp the surface of the drill pipe. On the contrary, when it is not necessary to clamp the drill pipe, the output end of the first motor 41 rotates clockwise, and at this time the six clamping blocks 47 open, and the drill pipe is no longer clamped. To prevent dirt on the surface of the drill pipe from adhering to the clamping surfaces of the clamping blocks 47, the output end of the first motor 41 rotates counterclockwise again. The sharp corner of the first clamping block 47 slides along the clamping surface of the second clamping block 47, and the sharp corner of the second clamping block 47 slides along the clamping surface of the third clamping block 47, and so on. Thus, when the six clamping blocks 47 are closed, the clamping surfaces of each clamping block 47 are shoveled, and then the dirt on the clamping surfaces of each clamping block 47 is shoveled into the interior of the material storage groove 44.

[0075] The turntable 43 is driven by the first motor 41 to rotate, causing each clamping block 47 to move along the straight chute and the hexagonal chute 45, thereby clamping the drill pipe. When the drill pipe is not clamped, by closing the six clamping blocks 47, the sharp corner of the previous clamping block 47 shovels the material on the clamping surface of the next clamping block 47, and then shovels the dirt on the clamping surface of each clamping block 47 into the storage tank 44, effectively preventing the phenomenon that excessive dirt accumulates and adheres to the clamping end after too many detections, achieving the effect of automatically cleaning the dirt on the clamping surface.

[0076] Embodiment 4, a test method for a high-precision deep well drilling rig test bench. According to the above-mentioned high-precision deep well drilling rig test bench, it includes the following steps:

[0077] S1: The deep well drilling rig passes the drill pipe through the compaction mechanism 6 and the environmental simulation mechanism 5 in sequence, and inserts it into the clamping mechanism 4, and drives the drill pipe to rotate.

[0078] S2: The detection mechanism 3 initially detects the torque of the drill pipe and judges whether the torque of the drill pipe is within the normal range.

[0079] S3: When the torque of the drill pipe is within the normal range, the feeding mechanism 7 conveys different materials above the conveying mechanism 8 into the environmental simulation mechanism 5 respectively, and the compaction mechanism 6 compacts each material respectively.

[0080] The more specific steps of S3 are as follows: S31: The extension of the output end of the first hydraulic cylinder 72 drives the clamping plate 79 to move, so that the tank body 822 is located between the two clamping plates 79. The retraction of the output end of the double-shaft hydraulic cylinder 73 drives the clamping plates 79 to approach each other, thereby clamping the tank body 822. The extension of the output end of the second hydraulic cylinder 76 drives the tank body 822 to move upward, thereby bringing the tank body 822 above the pouring plate 53. The rotation of the output end of the second motor 78 drives the tank body 822 to flip, thereby pouring the material inside the tank body 822 into the pouring plate 53 and then flowing into the simulation barrel 52.

[0081] S32: When the simulation barrel 52 is filled with materials, the retraction of the output end of the first air cylinder 63 drives the pressing disc 64 to move downward, thereby compacting the loose materials and making the environmental simulation more accurate. At this time, the torque of the drill pipe starts to be detected.

[0082] S4: The detection mechanism 3 respectively detects the torque generated when the drill pipe rotates when surrounded by different materials, and judges again whether the torque of the drill pipe is within the normal range.

[0083] The more specific steps of S4 are as follows: S41: When excessive torque is detected, it is determined that there are defects such as tiny cracks, pores, and inclusions on the surface of the drill pipe that are difficult to observe. Since the particles will fill into these cracks and pores, the particle filling will change the density and mass distribution of the drill pipe, making it uneven. This unevenness will cause an unbalanced centrifugal force when the drill pipe rotates, thereby increasing the torque of the drill pipe. At this time, the drill pipe is not suitable for further drilling operations.

[0084] S42: When too little torque is detected, it is determined that the drill pipe is corroded or mechanically damaged, resulting in pits or spiral grooves on the surface of the drill pipe. The grooves may change the mud flow path, form local eddies or lubricating films, reduce the viscous resistance, and thus reduce the torque of the drill pipe. At this time, the drill pipe is not suitable for further drilling operations.

[0085] S5: The feeding and discharging of materials are both automatic each time. And while discharging, it drives the materials inside the environmental simulation mechanism 5 to move.

[0086] The more specific steps of S5 are as follows: S51: When the tank body 822 is driven to move leftward, the stop bar 567 is hit by the fixed column 821 above the tank body 822. At this time, the contact end of the stop bar 567 is pressed against the left quadrant point of the fixed column 821. The stop bar 567 is driven by the fixed column 821 to move leftward, and the second baffle 565 is driven to slide along the inner wall of the first baffle 562, and the bending spring 561 is gradually compressed. Since both the second baffle 565 and the first baffle 562 are arc-shaped plates, the stop bar 567 also moves in an arc when moving until the tank body 822 moves below the discharge end of the discharge plate 54. The conveyor 81 stops driving the tank body 822 to move. At this time, the materials inside the simulation barrel 52 can flow into the inside of the tank body 822.

[0087] S52: When the discharge chute is opened, the materials inside the simulation barrel 52 start to flow outwards. At this time, the electric button 563 is no longer pressed by the pressing block 564. The electric button 563 sends a signal to the second air cylinder 551. The output end of the second air cylinder 551 starts to retract, driving the first gear 553 to mesh with the second gear 554 and the third gear 557 respectively. At this time, the second gear 554 drives the first gear 553 to rotate, thereby driving the third gear 557 to rotate, and further driving the scraping bar 556 to rotate. While the scraping bar 556 rotates, it can not only break up the compacted materials, but also push the last remaining materials towards the discharge chute, accelerating the discharge speed of the materials.

[0088] S53: When one of the tanks 822 is filled with materials, the conveyor 81 drives the tank 822 filled with materials to continue moving leftward. At this time, the contact end of the stop bar 567 presses against the upper quadrant point of the fixed column 821 until the fixed column 821 is displaced to the left of the stop bar 567. At this time, the stop bar 567 is no longer pressed, and the bent spring 561 extends to drive the stop bar 567 and the second baffle 565 to return to their original positions.

[0089] S54: When the discharge chute is closed, the electric button 563 is pressed by the pressing block 564. At this time, the second cylinder 551 is in a fully extended state, the first gear 553 cannot mesh with the second gear 554 and the third gear 557, and the scraping bar 556 cannot be driven to rotate.

[0090] S55: After the torques of the drill pipes have been detected for the materials in all three tanks 822, at this time, the three tanks 822 are located on the left side of the discharge plate 54. The conveyor 81 drives the three tanks 822 to move rightward to return to their original positions. Since the stop bar 567 is hinged to the connecting rod 566, when returning to the original position, the fixed column 821 drives the stop bar 567 to rotate without causing interference. Since a limiting plate 568 is provided on one side of the stop bar 567, when the three tanks 822 move leftward, the fixed column 821 hits the stop bar 567, and the stop bar 567 will not be driven to rotate.

[0091] S6: After the detection of the drill pipe is completed, the clamping mechanism 4 is opened to take out the drill pipe and then the clamping mechanism 4 is closed. When the clamping mechanism 4 is closed, the dirt at the clamping end is indirectly cleaned.

[0092] The more specific steps of S6 are as follows. S61: In the initial state, the clamping mechanism 4 is in an open state. When it is necessary to clamp the drill pipe, the output end of the first motor 41 rotates counterclockwise, driving the turntable 43 to rotate counterclockwise, and then driving the clamping block 47 to slide along the hexagonal chute 45, and the cylinder 46 to slide along the straight chute. At this time, the clamping surfaces of one side of the six clamping blocks 47 clamp the surface of the drill pipe. On the contrary, when it is not necessary to clamp the drill pipe, the output end of the first motor 41 rotates clockwise, and at this time the six clamping blocks 47 open, and the drill pipe is no longer clamped.

[0093] S62: To prevent the dirt on the surface of the drill pipe from adhering to the clamping surfaces of the clamping blocks 47, the output end of the first motor 41 rotates counterclockwise again. The sharp corner of the first clamping block 47 slides along the clamping surface of the second clamping block 47, and the sharp corner of the second clamping block 47 slides along the clamping surface of the third clamping block 47, and so on. Thus, when the six clamping blocks 47 are closed, the clamping surfaces of each clamping block 47 are shoveled, and then the dirt on the clamping surfaces of each clamping block 47 is shoveled into the storage tank 44.
