Description

Technical Field

[0001] This utility model relates to the field of drill pipe replacement technology, specifically a drill pipe replacement device for a geological exploration drilling rig. Background Technology

[0002] Geological exploration is a scientific and technological process that uses drilling, geophysical exploration, and other methods to study the Earth's internal structure, mineral resources, and geological formations. Its aim is to identify strata, geological structures, and mineral distribution, providing a basis for energy development and engineering construction. The drilling rig is the core equipment in geological exploration, and the drill pipe is its "arm," connecting the drill bit to the power system and transmitting torque and axial pressure. However, drill pipes are subjected to high pressure, torsion, wear, and corrosion over long periods, making them prone to thread damage, pipe deformation, or fatigue fracture. Failure to replace them promptly can lead to stuck drill bits, missed drill bits, or even equipment accidents, severely impacting exploration efficiency and safety.

[0003] In existing technologies, the drill rod changing device is typically installed on one side of the drilling rig. This device consists of a housing, a motor, a rotating rod, a chuck, and two clamping arms. The motor drives the rotating rod to rotate, causing multiple drill rods arranged circumferentially within the chuck to rotate. The clamping arms on one side of the drilling rig clamp and move the drill rods to perform the replacement. However, in actual use, when the robotic arm places the replacement drill rod into the chuck, there is still a certain distance between the bottom of the drill rod and the housing. When the robotic arm releases the drill rod from its restraint, the drill rod falls and collides with the housing, generating a significant impact force. This negatively impacts the stability of the changing device. Therefore, an improved drill rod changing device for geological exploration drilling rigs is needed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide a drill rod replacement device for geological exploration drilling rigs to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drill rod replacement device for a geological exploration drilling rig, comprising a housing, a support rod fixedly installed on the outside of the housing, a drive motor fixedly installed on the top of the housing, a rotating shaft fixedly installed on the output end of the drive motor, the rotating shaft being rotatably installed inside the housing, a chuck fixedly installed on the outside of the rotating shaft, a protective mechanism fixedly installed on the outside of the rotating shaft, and a limit mechanism provided inside the protective mechanism.

[0006] Preferably, the protection mechanism includes a support plate, which is slidably mounted on the outside of the rotating shaft. A guide block is fixedly mounted on the outside of the rotating shaft, and a tray is fixedly mounted on the outside of the rotating shaft. A positioning groove is provided inside the tray, and a first T-shaped block is slidably mounted inside the positioning groove. A shock-absorbing damper is fixedly mounted on the top of the first T-shaped block, and a second T-shaped block is fixedly mounted on the top of the shock-absorbing damper. This facilitates shock absorption of the placed drill rod, thereby preventing the housing from shaking due to large impact forces.

[0007] Preferably, a through groove is provided inside the support plate at the position corresponding to the guide block, and the guide block is slidably installed in the through groove to facilitate the guiding work of the support plate and prevent the support plate from rotating.

[0008] Preferably, a groove is provided inside the support plate at the position corresponding to the second T-shaped block, and the second T-shaped block is slidably installed in the groove, which facilitates the positioning of the second T-shaped block and the limiting of the support plate by the second T-shaped block.

[0009] Preferably, the limiting mechanism includes a threaded post, which is rotatably installed inside the tray. A hexagonal insert is fixedly installed on the top of the threaded post, and the hexagonal insert is rotatably installed with the tray. A lifting plate is threadedly installed on the outside of the threaded post, and the lifting plate is slidably installed with the tray. A stop block is fixedly installed on the top of the lifting plate. A guide post is fixedly installed inside the tray, and the lifting plate is slidably installed outside the guide post. This facilitates the limiting operation of the first T-shaped block after positioning, thereby facilitating the quick assembly and disassembly of the shock absorber damping.

[0010] Preferably, a through groove is provided inside the tray at the position corresponding to the stop block, and the stop block is slidably installed in the through groove. The through groove passes through the positioning groove, which facilitates the lifting and lowering of the stop block and facilitates blocking the first T-shaped block.

[0011] Compared with the prior art, this utility model provides a drill rod replacement device for geological exploration drilling rigs, which has the following beneficial effects:

[0012] 1. The drill rod replacement device of this geological exploration drilling rig, through its protective mechanism, facilitates the positioning of the shock-absorbing damping through the first and second T-blocks during use, and the guide block facilitates the guidance of the support plate, enabling the support plate to rise and fall smoothly. This allows the support plate to rotate with the positioning groove and the drill rod, preventing friction between the bottom of the positioning groove and the support plate. When the robotic arm places the drill rod inside the chuck, the drill rod falls downwards, and with the help of the shock-absorbing damping, the impact force is reduced, thus ensuring the stability of the casing.

[0013] 2. The drill rod replacement device of this geological exploration drilling rig, through the setting of the limiting mechanism, facilitates the rotation of the threaded column by the setting of the internal hexagonal rotating block during use, and with the cooperation of the guide column, it facilitates the upward movement of the lifting plate, thereby facilitating the upward movement of the stop block, facilitating the limiting of the first T-shaped block after positioning, and facilitating the quick disassembly and assembly of the shock-absorbing damper.

[0023] Example 1:

[0024] Please see Figure 1-4 This utility model provides a technical solution: a drill rod replacement device for a geological exploration drilling rig, comprising a housing 1. The housing 1 has two through slots for drill rod movement, symmetrically located inside the housing 1. Support rods 2 are fixedly installed on the outside of the housing 1, symmetrically arranged. The housing 1 is installed by connecting the support rods 2 to the drilling rig. A drive motor 3 is fixedly installed on the top of the housing 1, connected to the drilling rig carriage via wires for power supply. A rotating shaft 4 is fixedly installed at the output end of the drive motor 3, rotatably mounted inside the housing 1. Two chucks 5 are fixedly installed on the outside of the rotating shaft 4, symmetrically arranged for limiting the drill rod movement. A protective mechanism 6 is fixedly installed on the outside of the rotating shaft 4, with a limit mechanism 7 inside the protective mechanism 6.

[0025] Furthermore, the protection mechanism 6 includes a support plate 601, which is slidably mounted on the outside of the rotating shaft 4. A guide block 602 is fixedly mounted on the outside of the rotating shaft 4, and a tray 603 is fixedly mounted on the outside of the rotating shaft 4. The tray 603 has six positioning grooves 604, which are circumferentially formed inside the tray 603. A first T-shaped block 605 is slidably mounted inside the positioning groove 604. A shock-absorbing damper 606 is fixedly mounted on the top of the first T-shaped block 605, and a second T-shaped block is fixedly mounted on the top of the shock-absorbing damper 606. 607, the first T-block 605 and the second T-block 607 facilitate the positioning of the shock-absorbing damper 606, and the guide block 602 facilitates the guidance of the support plate 601, facilitating the smooth lifting and lowering of the support plate 601. This allows the support plate 601 to rotate with the positioning groove 604 and the drill rod, preventing friction between the bottom of the positioning groove 604 and the support plate 601. When the robotic arm places the drill rod inside the chuck 5, the drill rod falls downwards. With the cooperation of the shock-absorbing damper 606, the impact force is reduced, thus ensuring the stability of the housing 1.

[0026] Furthermore, a through groove is provided inside the support plate 601 at the position corresponding to the guide block 602, and the guide block 602 is slidably installed in the through groove, which facilitates the guiding work of the support plate 601 and the smooth lifting and lowering of 610.

[0027] Furthermore, a groove is provided inside the support plate 601 at the position corresponding to the second T-shaped block 607, and the second T-shaped block 607 is slidably installed in the groove, which facilitates the positioning of the second T-shaped block 607 and the limiting of the support plate 601 by the second T-shaped block 607.

[0028] Please see Figure 5 Furthermore, in conjunction with Embodiment 1, the limiting mechanism 7 includes a threaded post 701, which is rotatably installed inside the tray 603. A hexagonal swivel block 702 is fixedly installed on the top of the threaded post 701, and the hexagonal swivel block 702 is rotatably installed with the tray 603. A lifting plate 703 is threadedly installed on the outside of the threaded post 701, and the lifting plate 703 is slidably installed with the tray 603. A stop block 704 is fixedly installed on the top of the lifting plate 703. The positioning groove 604 contacts the first T-shaped block 605. A guide post 705 is fixedly installed inside the tray 603, and the lifting plate 703 is slidably installed outside the guide post 705. The hexagonal swivel block 702 facilitates the rotation of the threaded post 701 using a hexagonal tool. With the cooperation of the guide post 705, the lifting plate 703 moves upward, thereby facilitating the upward movement of the stop block 704, limiting the positioning of the first T-shaped block 605, and facilitating the quick assembly and disassembly of the shock-absorbing damper 606.

[0029] Furthermore, a through groove is provided inside the tray 603 at the position corresponding to the stop 704, and the stop 704 is slidably installed in the through groove. The through groove passes through the positioning groove 604, which facilitates the lifting and lowering of the stop 704 and facilitates blocking the first T-shaped block 605.

[0030] In actual operation, when this device is used, the installation of the housing 1 is completed by installing the support rod 2 to the drilling rig. The first T-block 605 is slid into the positioning groove 604, and the second T-block 607 is slid into the groove inside the support plate 601 to initially position the shock absorber 606, thus limiting the second T-block 607 to the support plate 601. The internal hexagonal block 702 is rotated using a hexagonal tool, and with the cooperation of the guide column 705, the lifting plate 7... 03 moves upward, causing the stop block 704 to move upward, blocking the first T-shaped block 605 and limiting the shock-absorbing damper 606. By starting the drive motor 3, the rotating shaft 4, support plate 601 and tray 603 rotate, and multiple shock-absorbing dampers 606 are installed in sequence. When changing the drill rod, the robotic arm places the drill rod inside the chuck 5. The drill rod falls downward under the action of gravity. With the cooperation of the shock-absorbing damper 606, the impact force is reduced and the housing 1 is protected.
