Description

Technical Field

[0001] The invention relates to the technical field of sampling equipment, and in particular to an intelligent drilling sampling device for engineering survey. Background Art

[0002] Drilling sampling is an important part of engineering survey work. It refers to taking a certain number of rock cores or mineral cores from the exploration project, and then analyzing, identifying and testing these samples to understand the distribution of underground geology.

[0003] At present, deep drilling sampling is usually carried out by cooperating with a drilling rig and a rope coring drill. The inner tube assembly of the rope coring drill is inserted into the outer tube assembly of the rope coring drill, and then the outer tube assembly is driven by the drilling rig to drive the inner tube assembly to rotate, so as to sample the deep soil layer. When the inner tube assembly is filled with soil, the winch assembly is pulled up by the winch to pull the inner tube assembly out of the outer tube assembly. Then, the inner tube assembly is manually tilted, and the holder on the inner tube assembly is manually unscrewed from the inner tube to loosen the core in the inner tube so that the core can slide out of the inner tube. The operation of manually holding the inner tube assembly to keep it tilted to remove the sample and manually disassembling and assembling the holder are cumbersome, time-consuming and laborious. Because the inner tube assembly is long and heavy, the arm is easily sore when the inner tube assembly is manually held to keep it tilted, which leads to loosening of the inner tube assembly, causing the inner tube assembly to shake, resulting in the core breaking during the removal process, affecting the integrity of the sample and the accuracy of sampling. In addition, manual operation methods have certain safety hazards, especially in high-risk working environments. Workers come into close contact with the inner tube assembly, which increases the risk of accidents. The shaking and instability of the inner tube assembly may also cause the operator to lose control, further increasing the risk of accidents. Summary of the invention

[0029] Before installing the rope coring drill 3 for drilling and sampling, first control the electric slider 7 to move rightward, the electric slider 7 moves rightward to drive the rotating shaft 61 to move rightward, the rotating shaft 61 moves rightward to drive the slide plate 5 to move rightward, and the entire telescopic electric swing frame 6 moves rightward accordingly, thereby driving the clamp 12 to move rightward, so as to prevent the clamping block 122 on the clamp 12 from hindering the subsequent installation of the rope coring drill 3. The electric slider 7 moves rightward to drive the slide bar 192 to move rightward, the electric slider 7 moves rightward to pull the sliding sleeve 191 to move rightward through the spring 3 193, and the sliding sleeve 191 moves rightward to drive the slide rail 8 to move rightward, and the lifting rod 9, the connecting plate 10 and the clamp 11 move rightward accordingly to avoid the driving motor 23, so as to avoid hindering the subsequent driving motor 23 from driving the internal threaded connecting pipe 24 to move down and dock with the outer pipe assembly 31. Next, the outer tube assembly 31 is placed into the through hole 27 on the hollow fixed block 26, and then the control cylinder 1 28 drives the two clamping blocks 1 29 to approach each other to clamp and fix the outer tube assembly 31, and then the winch is installed on the left side of the vertical plate 21, and the rope on the winch is passed around the wire frame 25, and the wire frame 25 can guide the rope, and the salvage assembly is connected to the rope of the winch, so that the inner tube assembly 32 is aligned with the outer tube assembly 31, and then the winch is controlled to release the rope, and under the action of gravity, the inner tube assembly 32 moves down and enters the outer tube assembly 31. After the inner tube assembly 32 is installed in the outer tube assembly 31, the salvage releases the salvage spearhead 322 on the inner tube assembly 32, and then the winch is controlled to reel in the rope to pull the salvage upward to the top of the drive motor 23 to avoid hindering the subsequent movement of the drive motor 23.

[0030] After the rope coring drill 3 is assembled, the YZ-axis moving platform 22 is controlled to drive the driving motor 23 to drive the internal threaded connecting tube 24 to move backward and align with the outer tube assembly 31. Then the YZ-axis moving platform 22 is controlled to drive the driving motor 23 to drive the internal threaded connecting tube 24 to move downward. At the same time, the driving motor 23 is controlled to drive the internal threaded connecting tube 24 to rotate. Since the outer tube assembly 31 is clamped and fixed by the clamping block 29, the internal threaded connecting tube 24 rotates and moves downward to be threadedly connected to the outer tube assembly 31. After the connection between the internal threaded connecting pipe 24 and the outer tube assembly 31 is completed, the control cylinder 28 drives the two clamping blocks 29 to move away from each other to loosen the outer tube assembly 31, so that the subsequent internal threaded connecting pipe 24 drives the outer tube assembly 31 to rotate, and controls the YZ axis moving platform 22 to drive the driving motor 23 to drive the internal threaded connecting pipe 24 to move continuously downward, the internal threaded connecting pipe 24 rotates and moves continuously downward to drive the outer tube assembly 31 to rotate and move continuously downward, the outer tube assembly 31 rotates and moves continuously downward to drive the inner tube assembly 32 to rotate and move continuously downward, and the outer tube assembly 31 and the inner tube assembly 32 then drill into the soil layer for sampling. After completing a sampling operation, the air cylinder 28 is controlled to drive the clamp block 29 to clamp and fix the outer tube assembly 31, and then the driving motor 23 is controlled to drive the internal threaded connecting tube 24 to reverse, and the YZ axis moving platform 22 is controlled to drive the driving motor 23 to drive the internal threaded connecting tube 24 to move upward. Since the outer tube assembly 31 is clamped and fixed by the clamp block 29, the internal threaded connecting tube 24 reverses and moves upward to separate from the outer tube assembly 31. Then, the YZ axis moving platform 22 is controlled to drive the driving motor 23 to drive the internal threaded connecting tube 24 to move forward to avoid the inner tube assembly 32, so as to avoid hindering the subsequent removal of the inner tube assembly 32 from the outer tube assembly 31.

[0031] After the outer tube assembly 31 is drilled into the soil layer, the height of the outer tube assembly 31 is lower than the hollow block 64. Before taking out the inner tube assembly 32, the electric slider 7 is first controlled to drive the entire telescopic electric swing frame 6 to move to the left and reset, thereby driving the clamp 12 to move to the left and align with the inner tube assembly 32. The electric slider 7 moves to the left and drives the slide bar 192 to move to the left. The electric slider 7 moves to the left and pushes the sliding sleeve 191 to move to the left through the spring 3 193. The sliding sleeve 191 moves to the left and drives the slide rail 8 to move to the left, thereby driving the clamp 11 to move to the left and align with the inner tube assembly 32. The winch is controlled to release the rope. Under the action of gravity, the salvage device moves down into the outer tube assembly 31 and hooks the salvage spearhead 322 on the inner tube assembly 32. The principle of releasing the salvage device and hooking the salvage spearhead 322 is a prior art and will not be repeated here. By controlling the winch to reel in the rope, the salvage device can be pulled upward, thereby pulling the inner tube assembly 32 upward from the outer tube assembly 31. The inner tube assembly 32 moves upward to push the block 122 to swing upward, and the spring 123 is compressed accordingly. When the slot at the bottom of the holder 323 on the inner tube assembly 32 is aligned with the block 122, under the reset action of the spring 123, the block 122 is pushed to swing downward and snap into the slot at the bottom of the holder 323. Then, the clamp 11 is controlled to clamp the inner tube 321 on the inner tube assembly 32, and then the electric slider 7 is controlled to drive the entire telescopic electric swing frame 6 to move rightward, thereby driving the inner tube assembly 32, the slide rail 8, the lifting rod 9, the connecting plate 10 and the clamp 11 to move rightward. At the same time, the winch is controlled to release the rope to avoid hindering the inner tube assembly 32 from moving rightward.

[0032] After the inner tube assembly 32 moves to the right to a suitable position, the control motor 1 65 drives the front rotating shaft 61 to rotate, thereby driving the front electric telescopic rod 62 and the L-shaped lifting plate 63 to swing to the lower left, and the hollow block 64, the rear electric telescopic rod 62 and the L-shaped lifting plate 63 swing to the lower left accordingly. The swinging of the hollow block 64 to the lower left drives the holder 323, the clamping member 12 and the driving member 13 to swing to the lower left, and the swinging of the holder 323 to the lower left drives the inner tube 321 to swing to the lower left, and the inner tube 321 swings to the lower left. The clamp 11 is pushed to move to the lower left. The clamp 11 moves to the lower left and pushes the lifting rod 9 to move to the lower left through the connecting plate 10. The slide rail 8 is then pushed to the left by the lifting rod 9. The lifting rod 9 slides downward in the slide rail 8. At the same time, the spring three 193 is stretched. At the same time, the winch is controlled to reel in the rope to pull the inner tube assembly 32, thereby locking the inner tube 321, and then locking the slide rail 8 to prevent the slide rail 8 from being pulled to the right by the spring three 193, thereby preventing the inner tube 321 from shaking left and right to improve stability. After the inner tube assembly 32 tilts to the left, the driving member 13 is controlled to drive the rotating ring 121 to rotate, the rotating ring 121 rotates to drive the block 122 to rotate, the block 122 rotates to drive the holder 323 to rotate, the holder 323 rotates to move downward and disengage from the inner tube 321, at the same time, the electric telescopic rod 62 is controlled to drive the L-shaped lifting plate 63 to drive the hollow block 64 to move downward, thereby driving the holder 12 to move downward, ensuring that the holder 12 remains engaged with the holder 323, and the holder 323 is disassembled. After the holder 323 is disassembled, the telescopic electric swing frame 6 is controlled to swing back to the vertical state to the upper right, and the holder 323 swings to the upper right to the vertical state, and the core in the inner tube 321 slides downward, and the removal of the core can be assisted by water flushing or knocking in the prior art. After the core is taken out, the telescopic electric swing frame 6 is controlled to swing to the lower left, thereby driving the holder 323 to swing to the lower left and align with the inner tube 321, and then the driving member 13 is controlled to drive the swivel 121 to reverse, and the reversal of the swivel 121 drives the block 122 to reverse, and the reversal of the block 122 pushes the holder 323 to reverse. At the same time, the electric telescopic rod 62 is controlled to drive the L-shaped lifting plate 63 to drive the hollow block 64 to move upward, thereby driving the clamping member 12 to move upward, and the block 122 pushes the holder 323 to move upward. The holder 323 rotates and moves upward to be threadedly connected to the inner tube 321, thereby realizing the installation of the holder 323. In this way, the device can not only automatically adjust the angle of the inner tube assembly 32, but also automatically disassemble and assemble the holder 323, thereby improving the degree of intelligence. There is no need to manually hold the inner tube assembly 32 to keep it tilted to take out the sample, which reduces the burden on the operator, reduces the manual operation steps, improves work efficiency, reduces the risk of shaking of the inner tube assembly 32, reduces the possibility of accidents, can better maintain the integrity of the core, and reduce the risk of large-scale breakage of the core in the inner tube 321.

[0033] After the installation of the holder 323 is completed, the telescopic electric swing frame 6 is controlled to swing back to the vertical state to the upper right, thereby pushing the inner tube assembly 32 to swing back to the vertical state to the upper right. At the same time, the winch is controlled to release the rope to ensure that the inner tube assembly 32 swings smoothly back to the vertical state to the upper right. The inner tube 321 swings to the upper right and pushes the clamp 11 to move to the upper right. The clamp 11 moves to the upper right and pushes the lifting rod 9 to move to the upper right through the connecting plate 10. The slide rail 8 is then pushed to the right by the lifting rod 9, and the lifting rod 9 slides upward in the slide rail 8. At the same time, the spring three 193 returns to its original state. Then the electric slider 7 is controlled to drive the entire telescopic electric swing frame 6 to move to the left, thereby driving the inner tube assembly 32, the slide rail 8, the lifting rod 9, the connecting plate 10 and the clamp 11 to move to the left, so that the inner tube assembly 32 is aligned with the outer tube assembly 31 to the left, and then the clamp 11 is controlled to release the inner tube 321, and then the winch is controlled to reel in the rope to pull the inner tube assembly 32 upward out of the hollow block 64 and the clamp 11, so that the subsequent telescopic electric swing frame 6, the clamp 12 and the clamp 11 can move to the right to avoid the block 122 hindering the subsequent inner tube assembly 32 from entering the outer tube assembly 31 for re-sampling.

[0034] like Figure 5-Figure 6 The driving member 13 includes a second motor 131 installed on the right side of the hollow block 64. A gear 132 is connected to the output shaft of the second motor 131 and the outer wall of the rotating ring 121. The two gears 132 are meshed. The second motor 131 drives the gear 132 thereon to rotate, and the rotating ring 121 is driven to rotate through the transmission of the gear 132, so that the entire clamping member 12 rotates to realize the disassembly and installation of the clamping seat 323.

[0035] See also Figure 7 The clamp 11 includes two cylinders 111 connected to the right sides of the two connecting plates 10, respectively. A hollow connecting block 112 is connected between the shells of the two cylinders 111. The hollow connecting block 112 is located directly above the hollow block 64. A circular hole 113 for accommodating the inner tube 321 is opened on the hollow connecting block 112. The telescopic rods of the two cylinders 111 are both extended into the hollow connecting block 112 and connected to a clamping block 113 for clamping the inner tube 321. 14. The shape of the second clamping block 114 is arc-shaped, which can better fit the inner tube 321. The clamping part of the second clamping block 114 is connected with a rubber block to buffer and protect the inner tube 321. The control cylinder 111 drives the two second clamping blocks 114 to approach each other to clamp the inner tube 321 to prevent the rotation of the inner tube 321 from affecting the disassembly and assembly of the holder 323. The control cylinder 111 drives the two second clamping blocks 114 to move away from each other to loosen the inner tube 321.

[0036] See also Figure 4 , Figure 8 , Fig. 9 and Fig.10The inner tops of the two L-shaped lifting plates 63 are connected with L-shaped connecting plates 14, and the sides of the two L-shaped connecting plates 14 close to each other are connected with guide blocks 15. The two guide blocks 15 are slidably sleeved with arc guide rails 16, and springs 17 are arranged in the arc guide rails 16. The two ends of the springs 17 are respectively connected to the arc guide rails 16 and the guide blocks 15. A guide plate 18 is connected between the left sides of the two arc guide rails 16. The guide plate 18 is semicircular in shape, and its radius is larger than the radius of the inner tube 321. The semicircular guide plate 18 can better fit with the inner tube 321, thereby effectively guiding the core and preventing the core from sliding from the front and rear sides and causing breakage.

[0037] After the outer tube assembly 31 is drilled into the soil layer, the height of the outer tube assembly 31 is lower than the guide plate 18. The outer tube assembly 31 will not hinder the guide plate 18 from moving left and right following the telescopic electric swing frame 6. After the guide plate 18 moves to the left following the telescopic electric swing frame 6, it is located on the left side of the inner tube assembly 32. When the L-shaped lifting plate 63 on the telescopic electric swing frame 6 swings to the lower left, the guide block 15 is pushed by the L-shaped connecting plate 14 to drive the arc guide rail 16 to swing to the lower left, and the guide plate 18 swings to the lower left accordingly. When the telescopic electric swing frame 6 drives the holder 323 to swing back to the vertical state to the upper right, the L-shaped connecting plate 14 is driven to swing to the upper right through the L-shaped lifting plate 63, and the guide block 15 is swung to the upper right accordingly, thereby pushing the arc guide rail 16 through the spring 2 17 to drive the guide plate 18 to swing to the upper right. When the guide plate 18 swings to the upper right and contacts with the inner tube 321, the guide plate 18 and the arc guide rail 16 cannot continue to swing to the upper right, so that the guide block 15 continues to swing to the upper right to compress the spring 2 17, and the arc guide plate 18 can catch the rock core that slides out of the inner tube 321 and guide the rock core to the right for subsequent collection of the rock core.
