Description

[0003] During geological exploration, drilling equipment delivers the drill rod to a predetermined depth underground. The hollow structure inside the drill rod can collect rock samples broken during the drilling process to form a core. After drilling is completed, the drill rod is lifted to the surface and opened to remove the core. Subsequently, geological staff use professional instruments such as X-ray diffractometers, scanning electron microscopes, and spectrometers to analyze the core to determine its physical properties, chemical composition, mineral composition and other characteristics, and then infer the geological history and evaluate the potential of mineral resources.

[0036] The present application embodiment provides a drill rod disassembly and assembly device, such as Figure 1 As shown, the drill rod disassembly and assembly device includes a first bracket 1, a fixing mechanism 2, a screwing mechanism 3, a moving mechanism 4 and a plurality of first lifting mechanisms 5.

[0037] The fixing mechanism 2 is connected to the first bracket 1 and is configured to fix and release the tail section of the drill pipe. The screwing mechanism 3 is connected to the first bracket 1 and is configured to clamp and rotate the outer shell and inner shell of the drill pipe. The moving mechanism 4 can be slidably connected to the first bracket 1 along the first direction and is configured to clamp the outer shell of the drill pipe and drive the outer shell of the drill pipe to move a preset distance along the first direction and release it after the outer shell and the tail section of the drill pipe are disconnected. A plurality of first lifting mechanisms 5 are arranged on the first bracket 1 at intervals along the first direction and are configured to move in the height direction and carry the drill pipe when moving to a high place. The first direction is the axial direction of the drill pipe when it is located at the fixing mechanism 2 and the screwing mechanism 3.

[0038] The fixing mechanism 2 fixes the tail section of the drill rod during the process of disassembling and assembling the drill rod. The screwing mechanism 3 is used to screw the outer shell and inner shell of the drill rod, and the screwing direction of the drill rod by the screwing mechanism 3 is opposite to that of the process of disassembling the drill rod. The moving mechanism 4 is used to move the outer shell of the drill rod disconnected from the tail section of the drill rod in a first direction, so that the outer shell of the drill rod is separated from the inner shell to facilitate screwing the inner shell. Multiple first lifting mechanisms 5 are used to carry the drill rod when disassembling and assembling the drill rod.

[0039] When using this drill pipe disassembly and assembly device to disassemble the drill pipe, place the drill pipe on multiple first lifting mechanisms 5, and make the tail section of the drill pipe located at the fixing mechanism 2 and the outer shell of the drill pipe located at the screwing mechanism 3. The fixing mechanism 2 fixes the tail section of the drill pipe, and the screwing mechanism 3 screws the outer shell of the drill pipe to disconnect the outer shell of the drill pipe from the tail section of the drill pipe; then, the moving mechanism 4 clamps the outer shell of the drill pipe multiple times and moves along the first direction and releases it, so that the outer shell of the drill pipe disengages from the inner shell of the drill pipe; finally, the screwing mechanism 3 screws the inner shell of the drill pipe to disconnect the inner shell of the drill pipe from the tail section of the drill pipe, and then the staff can take out the core from the inner shell.

[0040] When using this drill pipe disassembly and assembly device to assemble the drill pipe, place the inner shell from which the core has been taken out on multiple first lifting mechanisms 5 and at the position where the screwing mechanism 3 is located; the fixing mechanism 2 fixes the tail section of the drill pipe, and then the screwing mechanism 3 clamps the inner shell of the drill pipe and rotates it to thread-connect the inner shell of the drill pipe with the tail section of the drill pipe; then, place the outer shell on the moving mechanism 4, and the moving mechanism 4 clamps the outer shell of the drill pipe multiple times and moves along the first direction and releases it, so that the outer shell of the drill pipe is sleeved outside the inner shell of the drill pipe; finally, the screwing mechanism 3 clamps the outer shell of the drill pipe and rotates it to connect the outer shell of the drill pipe with the tail section of the drill pipe.

[0041] Therefore, when using this drill pipe disassembly and assembly device to disassemble and assemble the drill pipe, manpower and time are saved, and the disassembly and assembly efficiency of the drill pipe is improved.

[0042] In some embodiments of the present application, continue to refer to Figure 1 , the fixing mechanism 2 includes at least one first clamping jaw 21, and at least one first clamping jaw 21 is fixedly connected to the first bracket 1 and is configured to clamp and release the tail section of the drill pipe. Exemplarily, the fixing mechanism 2 includes two first clamping jaws 21 arranged in parallel, which can clamp the tail section of the drill pipe simultaneously and release the tail section of the drill pipe simultaneously.

[0043] In some embodiments of the present application, continue to refer to Figure 1 , the screwing mechanism 3 includes at least one initial screwing component 31 and at least one continuous screwing component 32. Exemplarily, the screwing mechanism 3 includes two initial screwing components 31 arranged in parallel and two continuous screwing components 32 arranged in parallel.

[0044] When removing the outer shell of the drill rod, first use the initial screwing assembly 31 to screw the outer shell of the drill rod to set an angle so that the outer shell of the drill rod and the tail section of the drill rod can be loosened; then use the continuous screwing assembly 32 to continuously rotate the outer shell of the drill rod so that the outer shell of the drill rod is gradually separated from the tail section of the drill rod. Similarly, when removing the inner shell of the drill rod, first use the initial screwing assembly 31 to screw the inner shell of the drill rod to set an angle so that the inner shell of the drill rod and the tail section of the drill rod can be loosened; then use the continuous screwing assembly 32 to continuously rotate the inner shell of the drill rod so that the inner shell of the drill rod is gradually separated from the tail section of the drill rod.

[0045] When connecting the inner shell of the drill pipe with the tail section of the drill pipe, firstly, the inner shell of the drill pipe is continuously rotated using the continuous screwing assembly 32 so that the inner shell of the drill pipe is gradually connected to the tail section of the drill pipe; then, the inner shell of the drill pipe is screwed to a set angle using the initial screwing assembly 31 so that the inner shell of the drill pipe is firmly connected to the tail section of the drill pipe. When connecting the outer shell of the drill pipe with the tail section of the drill pipe, firstly, the outer shell of the drill pipe is continuously rotated using the continuous screwing assembly 32 so that the outer shell of the drill pipe is gradually connected to the tail section of the drill pipe; then, the outer shell of the drill pipe is screwed to a set angle using the initial screwing assembly 31 so that the outer shell of the drill pipe is firmly connected to the tail section of the drill pipe.

[0046] Among them, Fig.16 As shown, the initial screwing assembly 31 includes a swing assembly 311, a first clamping claw 21 and a first actuator 312.

[0047] When the initial screwing assembly 31 is required to screw the outer shell and the inner shell of the drill pipe, the first clamping claw 21 clamps the outer shell and the inner shell of the drill pipe, and the actuating end of the first actuating member 312 drives the first clamping claw 21, so that the first clamping claw 21 swings on the first bracket 1 through the swinging assembly 311. By controlling the movement direction of the actuating end of the first actuating member 312, the first clamping claw 21 swings in different directions, thereby loosening or tightening the outer shell and the inner shell.

[0048] Exemplarily, the first actuating member 312 may be a hydraulic rod, and the first clamping claw 21 may be swung in different directions by extending or shortening the hydraulic rod, thereby loosening or tightening the outer shell and the inner shell.

[0049] Furthermore, if Fig.17 and Fig.18As shown, the swing assembly 311 includes an arc guide rail 3111, a swing seat 3112 and a swing roller 3113.

The second actuating member 323 is installed on the first bracket 1, and the actuating end of the second actuating member 323 is transmission-connected to the rotating roller 322 and is configured to drive the rotating roller 322 to rotate.

[0051] When the drill rod is disassembled, the second clamping claw 321 clamps the outer shell and inner shell of the drill rod, and the actuating end of the second actuating member 323 drives the rotating roller 322 to rotate. The rotating roller 322 is close to the outer shell and inner shell of the drill rod, and then the rotating roller 322 can drive the outer shell and inner shell to rotate continuously, so that the outer shell and inner shell of the drill rod are gradually separated from the tail section of the drill rod.

[0052] When assembling the drill rod, the second clamping claw 321 first clamps the inner shell of the drill rod, and the actuating end of the second actuating member 323 drives the rotating roller 322 to rotate, and the rotating roller 322 is close to the inner shell of the drill rod, and then the rotating roller 322 can drive the inner shell to rotate continuously, so that the inner shell of the drill rod is gradually connected to the tail section of the drill rod; then, the second clamping claw 321 clamps the outer shell of the drill rod, and the actuating end of the second actuating member 323 drives the rotating roller 322 to rotate, and the rotating roller 322 is close to the outer shell of the drill rod, and then the rotating roller 322 can drive the outer shell to rotate continuously, so that the outer shell of the drill rod is gradually connected to the tail section of the drill rod.

[0054] In some embodiments of the present application, Figure 4As shown, the moving mechanism 4 includes a sliding bracket 41, a first telescopic rod 42 and at least one first clamping claw 21. The sliding bracket 41 can be slidably connected to the top of the first bracket 1 along the first direction. At least one first clamping claw 21 is fixedly connected to the sliding bracket 41. Exemplarily, two first clamping claws 21 are fixedly connected to the sliding bracket 41, and the two first clamping claws 21 can clamp the outer shell of the drill rod at the same time and release the outer shell of the drill rod at the same time. The two ends of the first telescopic rod 42 are respectively connected to the first bracket 1 and the sliding bracket 41, and are configured to drive the sliding bracket 41 to slide along the first direction. Exemplarily, the first telescopic rod 42 can be a hydraulic cylinder, and the two ends of the hydraulic cylinder are respectively hinged to the first bracket 1 and the sliding bracket 41.

[0055] When it is necessary to drive the outer shell of the drill rod to move, the first clamping claw 21 clamps the outer shell of the drill rod, and then the first telescopic rod 42 drives the sliding bracket 41 to move a preset distance along the first direction on the first bracket 1, and the first clamping claw 21 releases the outer shell of the drill rod. After the first telescopic rod 42 drives the sliding bracket 41 to move a preset distance along the first direction on the first bracket 1, the first clamping claw 21 and the telescopic rod 72 repeat the above actions, thereby moving the outer shell of the drill rod along the first direction. When disassembling the drill rod, the moving mechanism 4 drives the outer shell of the drill rod away from the tail section of the drill rod; when assembling the drill rod, the moving mechanism 4 drives the outer shell of the drill rod close to the tail section of the drill rod.

[0056] Some embodiments of the present application show the specific structure of the first clamping claw 21. Fig.10 and Fig.11 As shown, the first clamping claw 21 includes a first clamping frame 211, two first clamping assemblies 212 and two third actuating members 213. The first clamping frame 211 is connected to the first bracket 1. The two first clamping assemblies 212 are arranged on the first clamping frame 211 facing each other, and can be slidably connected to the first clamping frame 211 along the second direction. The second direction is the axial direction of the drill pipe when it is clamped by the two first clamping assemblies 212. The two third actuating members 213 are installed on the first clamping frame 211, and the actuating ends of the two third actuating members 213 are respectively connected to the two first clamping assemblies 212, and are configured to drive the two first clamping assemblies 212 to approach each other to clamp and fix the drill pipe.

[0057] When the first clamping claw 21 is required to perform a clamping action, the actuating ends of the two third actuating members 213 respectively drive the two first clamping assemblies 212 to slide along the second direction on the first clamping frame 211 and move closer to each other until the two first clamping assemblies 212 are pressed against the drill rod. When the first clamping claw 21 is required to perform a releasing action, the actuating ends of the two third actuating members 213 respectively drive the two first clamping assemblies 212 to slide along the second direction on the first clamping frame 211 and move away from each other until the two first clamping assemblies 212 are separated from the drill rod.

[0058] Further, continue to refer to Fig.11 The first clamping assembly 212 includes a first slider 2121, a first fixing frame 2122 and two clamping teeth 2123. The first slider 2121 is slidably connected to the first clamping frame 211 along the second direction, and is connected to the actuating end of the third actuating member 213. The first fixing frame 2122 is connected to the first slider 2121, and a groove concave toward the first slider 2121 is provided on the side of the first fixing frame 2122 away from the first slider 2121. The two clamping teeth 2123 are hinged to the side of the first fixing frame 2122 away from the first slider 2121, and are respectively located above and below the groove.

The two clamping teeth 2123 on the first fixing frame 2122 are used to press against the drill rod, and the groove between the two clamping teeth 2123 is used to avoid the drill rod, so as to prevent the first fixing frame 2122 from interfering with the drill rod when the first clamping claw 21 clamps the drill rod.

[0060] Furthermore, the two clamping teeth 2123 are hinged between the first fixing frame 2122, so that the two clamping teeth 2123 can adapt to the outer shell and the inner shell of the drill rod of different sizes.

[0062] When the second clamping claw 321 is required to perform a clamping action, the actuating ends of the two fourth actuating members 3213 respectively drive the two second clamping assemblies 3212 to slide along the second direction on the second clamping frame 3211 and move closer to each other until the two second clamping assemblies 3212 are pressed against the drill rod. When the second clamping claw 321 is required to perform a releasing action, the actuating ends of the two fourth actuating members 3213 respectively drive the two clamping assemblies to slide along the second direction on the second clamping frame 3211 and move away from each other until the two second clamping assemblies 3212 are separated from the drill rod.

[0063] Furthermore, when the second clamping claw 321 clamps the drill rod, the rotating roller 322 is driven by the second actuating member 323 to rotate, and then the rotating roller 322 drives the outer shell and the inner shell of the drill rod to rotate.

[0069] When the first lifting mechanism 5 is required to carry the drill rod, the first telescopic member 52 is extended to raise the first lifting frame 51 to a preset position; when the first lifting mechanism 5 is not required to carry the drill rod, the first telescopic member 52 is shortened to lower the first lifting frame 51 to a preset position. The first supporting roller 53 is used to place the drill rod, and when the drill rod or the outer shell and inner shell of the drill rod move along the first direction, the first supporting roller 53 rotates.

[0070] Further, continue to refer to Figure 8 Each first lifting mechanism 5 further includes a plurality of first guide wheels, which are arranged at intervals in the vertical direction and connected to the first bracket 1. The first lifting bracket 51 is provided with a vertically extending first guide slot 511, and the first guide wheel extends into the first guide slot 511.

[0071] The plurality of first guide wheels are used to guide the moving direction of the first lifting frame 51. Specifically, when the first telescopic member 52 drives the first lifting frame 51 to move, the plurality of first guide wheels connected to the first bracket 1 roll in the first guide groove 511, thereby moving the first lifting frame 51 in the vertical direction.

[0072] In some embodiments of the present application, Figure 1 As shown, the drill rod disassembly and assembly device further includes a plurality of second lifting mechanisms 6, which are arranged at intervals on the first bracket 1 along the first direction, and are configured to move in the height direction and carry the drill rod when moving to a high position. When the screwing mechanism 3 drives the outer shell and the inner shell of the drill rod to rotate, the plurality of second lifting mechanisms 6 are raised to a preset position and carry the drill rod.

[0073] Specifically, Fig. 9 As shown, the second lifting mechanism 6 includes a second lifting frame 61, a second telescopic member 62 and two second supporting rollers 63. The two ends of the second telescopic member 62 are respectively connected to the first bracket 1 and the second lifting frame 61, and are configured to drive the second lifting frame 61 to move in the height direction; the two second supporting rollers 63 are rotatably connected to the top of the second lifting frame 61, and the axes of the two second supporting rollers 63 extend along the first direction; when the second lifting frame 61 is located at a high position, the drill rod is located between the two second supporting rollers 63, and the two second supporting rollers 63 rotate with the drill rod.

[0074] When the second lifting mechanism 6 needs to be raised to a preset height to carry the drill rod, the second telescopic member 62 is controlled to extend, thereby driving the second lifting frame 61 to rise to a preset height, and the drill rod is located between the two second supporting rollers 63. When the screwing mechanism 3 drives the drill rod to rotate, the two second supporting rollers 63 support the drill rod and rotate.

[0075] The second lifting mechanism 6 further includes a plurality of second guide wheels which are arranged at intervals in the vertical direction and connected to the first bracket 1. The second lifting bracket 61 is provided with a vertically extending second guide slot 611, and the second guide wheel extends into the second guide slot 611.

[0076] The plurality of second guide wheels are used to guide the moving direction of the second lifting frame 61. Specifically, when the second telescopic member 62 drives the second lifting frame 61 to move, the plurality of second guide wheels connected to the first bracket 1 roll in the guide groove, thereby moving the second lifting frame 61 in the vertical direction.

[0077] In some embodiments of the present application, Figure 1 As shown, the drill rod disassembly and assembly device also includes a positioning mechanism 7, which is installed on the first bracket 1 and is configured to push the drill rod to move along a first direction before the drill rod is operated by the screwing mechanism 3, so that the drill rod is moved to a preset screwing position.

[0078] Before disassembly, the rear end of the drill rod needs to be located at the position of the fixing mechanism 2, and the outer shell and inner shell of the drill rod need to be located at the screwing mechanism 3. However, when the drill rod is placed in the fixing mechanism 2 and the screwing mechanism 3, the position of the drill rod may be inaccurate, resulting in disassembly failure.

[0080] When the positioning mechanism 7 pushes the drill rod, the telescopic rod 72 extends along the first direction, and the front end of the telescopic rod 72 drives the push plate 73 to move, and then the push plate 73 pushes the end of the drill rod extending from the groove into the installation frame 71, so that the drill rod moves along the first direction.

[0082] After the outer shell of the drill rod is disassembled, the transfer mechanism 8 can transfer the outer shell of the drill rod away from the first bracket 1 to prevent the outer shell of the drill rod from hindering further disassembly of the drill rod.

[0083] Specifically, Figure 5A and Figure 5B As shown, the transport mechanism 8 includes a first transport support 81, a second transport support 82, at least one first transport actuator 83, at least one transport clamping claw 84 and a sliding assembly 85.

The sliding assembly 85 is connected to the first transport support 81 and is configured to drive the first transport support 81 to move along the first direction.

[0084] During the process of disassembling the drill rod, first, the sliding assembly 85 drives the first transfer bracket 81 to move along the first direction, so that the transfer clamping claw 84 is located above the outer shell of the drill rod; secondly, the actuating end of the first transfer actuator 83 drives the second transfer bracket 82 to move downward until the outer shell of the drill rod is located on the inner side of the transfer clamping claw 84; then, the transfer clamping claw 84 grabs the outer shell of the drill rod, and the actuating end of the first transfer actuator 83 drives the second transfer bracket 82 to move upward until the outer shell of the drill rod reaches a preset height; finally, the sliding assembly 85 drives the first transfer bracket 81 to move along the first direction to above the temporary storage position, and the actuating end of the first transfer actuator 83 drives the second transfer bracket 82 to move downward to the temporary storage position, and the transfer clamping claw 84 releases the outer shell of the drill rod.

[0085] During the process of assembling the drill rod, first, the sliding assembly 85 drives the first transfer bracket 81 to move along the first direction, so that the transfer clamping claw 84 is located above the temporary storage position; secondly, the actuating end of the first transfer actuator 83 drives the second transfer bracket 82 to move downward until the outer shell of the drill rod is located on the inner side of the transfer clamping claw 84; then, the transfer clamping claw 84 grabs the outer shell of the drill rod, and the actuating end of the first transfer actuator 83 drives the second transfer bracket 82 to move upward until the outer shell of the drill rod reaches a preset height; finally, the sliding assembly 85 drives the first transfer bracket 81 to move along the first direction to above the first bracket 1, and the actuating end of the first transfer actuator 83 drives the second transfer bracket 82 to move downward until the outer shell of the drill rod is placed on multiple first lifting mechanisms 5, and the transfer clamping claw 84 releases the outer shell of the drill rod.

[0086] Specifically, Figure 6As shown, the transport clamping claw 84 includes a second transport actuator 841, a first clamp 842, a second clamp 843 and a fixed beam 844.

The two ends of the second transport actuator 841 are respectively connected to the top of the first clamp 842 and the top of the second clamp 843, so that the bottom end of the first clamp 842 and the bottom end of the second clamp 843 are close to each other to grab the drill rod, and the bottom end of the first clamp 842 and the bottom end of the second clamp 843 are separated to release the drill rod.

[0087] When it is necessary to use the second transfer actuator 841 to clamp the drill rod, the two ends of the second transfer actuator 841 drive the top end of the first clamp 842 and the top end of the second clamp 843 to move away from each other, so that the bottom end of the first clamp 842 and the bottom end of the second clamp 843 are close to each other, so that the first clamp 842 and the second clamp 843 clamp the drill rod; when it is necessary to release the drill rod, the two ends of the second transfer actuator 841 drive the top end of the first clamp 842 and the top end of the second clamp 843 to move closer to each other, so that the bottom end of the first clamp 842 and the bottom end of the second clamp 843 are away from each other, so that the drill rod is released from between the first clamp 842 and the second clamp 843.

[0088] Further, continue to refer to Figure 6 The transport clamping claw 84 also includes two V-shaped clamping blocks 845, which are rotatably connected to the bottom end of the first clamping body 842 and the bottom end of the second clamping body 843, respectively, and the openings of the two V-shaped clamping blocks 845 are arranged to face each other.

[0089] When the bottom end of the first clamp body 842 and the bottom end of the second clamp body 843 are close to each other, the two V-shaped clamp blocks 845 are close to the drill rod until the inner side of the V-shaped clamp block 845 is close to the drill rod, thereby clamping the drill rod.

[0090] Specifically, Figure 7 As shown, the sliding assembly 85 includes a fixed frame 851, a third transfer actuator 852 and a slide rail 853. The third transfer actuator 852 is mounted on the fixed frame 851, and the actuating end of the third transfer actuator 852 is connected to the first transfer bracket 81, and is configured to drive the first transfer bracket 81 to move along the first direction. The slide rail 853 is extended along the first direction and arranged on the fixed frame 851, and the first transfer bracket 81 is slidably connected to the slide rail 853.

[0091] Exemplarily, the third transfer actuator 852 includes a motor, a reducer, a driving sprocket, a driven sprocket and a chain; the reducer is connected to the fixed frame 851, the rotating shaft of the motor is connected to the input shaft of the reducer, the driving sprocket is installed on the output shaft of the reducer, the driven sprocket is rotatably connected to the fixed frame 851, the chain extends along a first direction and is wound around the driving sprocket and the driven sprocket, and the first transfer bracket 81 is connected to the chain.

[0095] Specifically, Fig.15 As shown, the ejection mechanism 10 includes a top seat 101, a top rod 102 and a second telescopic rod 103. One end of the top rod 102 is fixedly connected to the top seat 101 and extends along a first direction. Both ends of the second telescopic rod 103 are respectively connected to the second bracket 91 and the top seat 101, and are configured to drive the top seat 101 to move in the height direction.

[0096] When the ejection mechanism 10 is working, the second telescopic rod 103 is extended to raise the top seat 101 to a preset height, so that the ejector rod 102 is aligned with the end of the drill rod. When the outer shell of the drill rod moves along the first direction, the ejector rod 102 presses against the inner shell of the drill rod, and then the outer shell and the inner shell of the drill rod are gradually separated.

[0097] Further, continue to refer to Fig.15 The ejection mechanism 10 further includes two limiting plates 104, which are spaced apart and connected to the top seat 101, and a passage for the outer shell of the drill rod to pass through is formed between the two limiting plates 104.
