Technical Field

[0001] This invention relates to the field of geothermal drilling technology, and in particular to a drilling platform, a drilling platform support box, and a pipe arrangement method. Background Technology

[0002] With the increasing demand for energy, the development of geothermal resources has gradually become an important means of energy acquisition. However, existing geothermal drilling rigs rely heavily on manual operation for pipe laying, which is labor-intensive and requires a large area. In particular, traditional drilling rigs often use a two-tiered platform structure for storing and operating drill pipes, but this structure occupies a large space and is difficult to adapt to geothermal drilling work in confined urban areas. Although automated drill pipe laying systems have made some progress on oil drilling rigs, these systems are usually also bulky and designed for large well sites, making them difficult to apply directly to geothermal development in urban well sites. While powered catwalks can achieve automatic drill pipe transport, their complex structure and large space requirements make them unsuitable for urban well sites. Therefore, there is an urgent need for a pipe laying system and method that is compact, improves operational efficiency, and is adaptable to confined spaces.

[0003] To address the shortcomings of existing technologies, this invention aims to provide a compact, intelligent, and miniaturized robotic pipe-laying system suitable for geothermal drilling operations.

[0034] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0035] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0036] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0037] Example 1, referring to Figure 1 ~ Figure 5 This is the first embodiment of the present invention, which provides a drilling platform, including a drilling platform surface 100 and one or more support boxes 200. The drilling platform surface 100 is supported by a bottom support structure and is set parallel to the ground at a certain height, forming a stable working platform and serving as the main load-bearing structure of the drilling platform. Preferably, the drilling platform surface 100 is rectangular, which facilitates the arrangement of the installation position 101 and other auxiliary equipment, and facilitates docking and arrangement with surrounding equipment.

[0038] The drill table surface 100 is provided with mounting positions 101 for accommodating and fixing the root box 200. Fixing the root box 200 on the drill table surface 100 also improves the overall stability of the drill table. Preferably, the mounting position 101 is a rectangular groove, which is set on one side of the drill table surface 100. One side of the mounting position 101 coincides with one side of the drill table surface 100, and the other sides of the mounting position 101 are either parallel or perpendicular to the sides of the drill table surface 100. This facilitates the positioning of the root box 200 during installation and also facilitates the processing of the mounting position 101. The number of mounting positions 101 and root boxes 200 are the same and correspond one-to-one.

[0039] Furthermore, the mounting positions 101 are evenly and symmetrically distributed along the horizontal direction on the drilling platform 100, and each support box 200 is independent of each other. When installing or removing the support box 200 from the mounting position 101, they will not affect each other.

[0040] The shape of the stand box 200 matches the shape of the mounting position 101. The stand box 200 can be installed and fixed on the mounting position 101 during use, and can also be removed from the mounting position 101 when not in use. The top of the stand box 200 protrudes from the drill table surface 100, which facilitates the storage and removal of drill rods G. The lower end of the stand box 200 is lower than the lower surface of the drill table surface 100, ensuring that the weight of the stand box 200 does not rest entirely on the drill table surface 100. The bottom of the stand box 200 is in direct or indirect contact with the ground, further reducing the pressure of the stand box 200 on the drill table surface 100. At the same time, after the stand box 200 is installed on the mounting position 101, it can provide a certain support for the drill table surface 100. The more drill rods G stored in the stand box 200, the stronger the support provided to the drill table surface 100.

[0041] The placement method of the support box 200 reduces the support strength required for the drill platform surface 100. This ensures that while the support strength of the drill platform is reduced due to its smaller size, the weight of other components can be reasonably distributed, allowing the drill platform to maintain its strength and stability in a smaller area.

[0042] The design of the Root Box 200 makes the overall size of the drilling platform smaller, making it more suitable for the needs of geothermal development in areas with limited space.

[0043] Preferably, the storage compartments 201 are periodically and densely arranged inside the root box 200, with the opening located on the top surface of the root box 200 to facilitate the storage and retrieval of the drill rod G; each storage compartment 201 can accommodate one drill rod G, and each storage compartment 201 is independent of each other to ensure that the drill rods G do not interfere with each other when storing and retrieving them.

[0044] Each of the storage compartments 201 is equipped with a hydraulic cylinder at the bottom, which can push out the drill rod G for easy storage and retrieval.

[0045] In use, the standpipe box 200 is installed on the mounting position 101 of the drill platform 100, so that the top of the standpipe box 200 protrudes from the drill platform 100 and the bottom of the standpipe box 200 is in direct or indirect contact with the ground, so that the weight of the standpipe box 200 is not borne entirely or mostly by the drill platform 100. Such a standpipe box 200 can be installed on a scaled-down drill platform. When the overall volume of the drill platform is reduced and the load-bearing capacity is reduced, it does not add extra pressure to the drill platform 100. It also provides a place for storing and retrieving drill rods G, while improving the overall stability of the drill platform. The receiving compartment 201 set on the standpipe box 200 can accommodate a single drill rod G, ensuring that there is a certain distance between multiple drill rods G so as not to interfere with each other and to facilitate the retrieval of drill rods G.

[0046] When the stand-up box 200 is fixed on the mounting position 101 of the drill platform 100, the bottom of the stand-up box 200 directly or indirectly contacts the ground, without pressing its own weight onto the drill platform 100. This not only reduces the burden on the drill platform 100, but also provides some support for the drill platform 100. After the receiving chamber 201 receives the drill rod G, the mass of the stand-up box 200 increases, which further improves the overturning resistance of the drill platform 100.

[0047] This embodiment achieves stable fixation and reasonable layout of the stand box 200 by setting a rectangular groove mounting position 101 on the rectangular drill platform 100 that matches the stand box 200. The stand box 200 adopts a detachable design, with a mounting position 101 at the top for easy access to and from the drill pipe G, and the lower end in direct or indirect contact with the ground to reduce pressure on the drill platform 100, thereby ensuring that the drill platform remains stable even when the ground's support capacity decreases; at the same time, the dense distribution of the storage compartments 201 optimizes the storage space for the drill pipe G. This design reduces the area of ​​the drill platform, making it more suitable for urban environments, without reducing the stability of the drill platform or the load-bearing capacity for the drill pipe G, and also enhances the space utilization and structural stability of the drill platform, providing more flexible operational options and meeting the diverse needs of actual drilling operations.

[0048] Example 2, refer to Figures 1-6 This is the second embodiment of the present invention. Unlike the first embodiment, the mounting position 101 is a right-angled trapezoidal groove, and there are multiple of them, symmetrically arranged on one side of the drilling platform 100. The inclined side of the mounting position 101 coincides with one side of the drilling platform 100, which facilitates the installation and disassembly of the support box 200. The distance between the top and bottom edges of the mounting position 101 matches the width of the support box 200. The non-inclined side of the mounting position 101 is neither parallel nor perpendicular to the edge of the drilling platform 100, which helps to improve the overturning resistance of the drilling platform 100.

[0049] In use, the standpipe box 200 is installed on the mounting position 101 of the drill platform 100, so that the top of the standpipe box 200 protrudes from the drill platform 100, and the bottom of the standpipe box 200 is in direct or indirect contact with the ground. This prevents the drill platform 100 from bearing all or most of the weight of the standpipe box 200. This design allows the standpipe box 200 to be installed on a scaled-down drill platform. When the overall volume of the drill platform is reduced, resulting in a decrease in load-bearing capacity, it does not add extra pressure to the drill platform 100. It also provides a storage and retrieval location for the drill rod G, while improving the overall stability of the drill platform. The receiving chamber 20... 1. After accommodating the drill pipe G, the mass of the stand box 200 increases, which can improve the overturning resistance of the drill platform 100. At the same time, since the mounting position 101 is a right-angled trapezoidal groove, the edge of the stand box 200 fits with the edge of the mounting position 101. However, the edge of the stand box 200 is not parallel to the edge of the drill platform 100. If the drill platform 100 has a tendency to overturn due to excessive wind or earthquakes, the presence of the stand box 200 will prevent the drill platform 100 from overturning because the edge of the stand box 200 is not parallel to the edge of the drill platform 100, thus further improving the overturning resistance of the drill platform 100.

[0050] The receiving chamber 201 on the standpipe box 200 can accommodate a single drill rod G, ensuring that multiple drill rods G are spaced apart to prevent interference and facilitate easy access. As the standpipe box 200 gradually accommodates the drill rod G, it also increases the support strength of the drill platform 100, improving its overturning resistance. When the standpipe box 200 is fixed to the mounting position 101 on the drill platform 100, its bottom directly or indirectly contacts the ground, without placing its own weight on the drill platform 100. This not only reduces the burden on the drill platform 100 but also provides some support. Furthermore, the increased mass of the standpipe box 200 after accommodating the drill rod G further enhances the overturning resistance of the drill platform 100.

[0051] This embodiment achieves stable installation and reasonable layout of the stand box 200 by setting a right-angled trapezoidal groove mounting position 101 on the rectangular drill platform 100 that matches the stand box 200. The stand box 200 adopts a detachable design, with a mounting position 101 at the top for easy access to drill pipe G. The lower end directly or indirectly contacts the ground to reduce pressure on the drill platform 100, ensuring that the drill platform remains stable even when the overall volume and floor area of ​​the drill platform are reduced, resulting in a decrease in support capacity. At the same time, the close-packed distribution of the storage compartments 201 optimizes the storage space for drill pipe G. While ensuring the storage capacity of the stand box 200 for drill pipe G, it also provides a certain distance between the drill pipe Gs to avoid mutual interference during storage and retrieval. This design reduces the area of ​​the drill platform, making it more suitable for urban environments, without reducing the stability of the drill platform or the load-bearing capacity for drill pipe G. It also enhances the space utilization and structural stability of the drill platform, providing more flexible operational options and meeting the diverse needs of actual drilling operations.

[0052] Example 3, referring to Figures 1-10 This is the third embodiment of the present invention, which is based on the first embodiment.

[0053] The drilling platform 100 is equipped with an installation position 101 and a wellhead H. The drilling platform 100 bears the weight of various drilling equipment, supports the installation and operation of the equipment, and provides working space. The wellhead H is located on the side of the drilling platform 100 that is off-center from the center of the drilling platform 100, and is used to move the drill pipe G up and down. The top drive 300 is located on top of the wellhead H, and is used to connect the drill pipe G and provide power to the drill pipe G to adjust its position. The wellhead H is located horizontally on one of the virtual dividing lines X that pass through the geometric center of the drilling platform 100. On one side; the mounting position 101 is located on the other side of the virtual dividing line X in the horizontal direction. Since the top drive 300 is provided on the top of the wellhead H, and the stand box 200 is installed on the mounting position 101, this layout can effectively balance the center of gravity of the drilling platform 100. The weight and applied force of the wellhead H and the top drive 300 are concentrated on one side, while the mounting position 101 and the stand box 200 are on the other side, forming a lever effect, which enhances the overall stability of the drilling platform, more rationally distributes the structural strength of the drilling platform, and reduces the risk of overturning.

[0054] Meanwhile, separating the wellhead H from the installation position 101 optimizes the operation process. During drilling operations, operators can more easily access and store the drill pipe G from one side without interfering with the drilling work. This improves space utilization by staggering the top drive 300 and the stand box 200, reducing interference with operators and increasing operational efficiency. It also increases the flexibility of the drilling platform, allowing space on the drilling platform surface 100 beyond the wellhead H and installation position 101 to accommodate motors or control panels, among other components.

[0055] Mounting position 101 is directly opened on the drilling platform 100, allowing the bottom of the stand box 200 to be placed directly or indirectly on the ground. Therefore, there is no need to set up a second-level platform on the drilling platform 100 to store drill rods; instead, the top of the stand box 200 directly mates with the mounting position 101. Since the stand box 200 no longer bears all the weight on the drilling platform 100, the support components under the drilling platform 100 can be reduced in size and strength, thereby reducing the overall footprint of the device while maintaining its stability. At the same time, the stand box 200 is placed directly in the mounting position 101, rather than next to the drilling platform 100, which also reduces the footprint. The placement and removal of drill rods G are faster and more convenient through the stand box 200. This type of drilling platform is more suitable for places with small construction sites, such as urban areas.

[0056] Specifically, the operating component 400 includes a gripper 401 for gripping and releasing the drill rod G; the gripper 401 includes a gripper 401a, which is composed of one or more coaxially arranged grippers to improve the stability of gripping and releasing the drill rod G. Preferably, when there are multiple grippers 401a, the axes of the grippers 401a coincide and there is sufficient distance between them to improve the stability of holding the drill rod G while reducing the difficulty of operation.

[0057] The operating component 400 also includes a movable component 402 for adjusting the position of the gripper 401. The movable component 402 is located at the end of the gripper 401 and includes a rotating arm 402a and a telescopic arm 402e. The gripper 401 cooperates with the telescopic arm 402e and the rotating arm 402a. The telescopic arm 402e can adjust the distance between the gripper 401 and the rotating arm 402a, and the rotating arm 402a can adjust the orientation of the gripper 401 to facilitate gripping and placing drill rods at different angles.

[0058] The drill pipe G is a component used in drilling operations to transmit rotational power and downforce. It consists of a male connector, a female connector, and a pipe body. The female connector of the first drill pipe and the male connector of the next drill pipe are threaded together. The pipe storage compartment is a device used to store and manage drill pipes. It is placed on one side of the drilling rig for easy access by the robotic arm, thus reducing manual labor. The top drive 300 is a component used to drive the drill pipe G to rotate and complete the drilling operation. The top drive 300 is mounted on the derrick of the drilling rig, with the wellhead H directly below it. The top drive inserts or removes the drill pipe G into the well through the wellhead H.

[0059] The movable component 402 also includes a translation arm 402b, a fixed slide rail 402c, and a movable slide rail 402d; one end of the rotating arm 402a is engaged with the translation arm 402b and can move on the translation arm 402b; the translation arm 402b is preferably a column perpendicular to the drill platform surface, and its bottom engages with the fixed slide rail 402c and the movable slide rail 402d. The translation arm 402b can translate along the fixed slide rail 402c and the movable slide rail 402d, and can also rotate along the bottom axis of the translation arm 402b; the fixed slide rail 402c is fixed to the top of the drill platform surface 100 and is located between the wellhead H and the stand box 200; a movable slide rail 402d is provided between the two fixed slide rails 402c, and the movable slide rail 402d can rotate on the drill platform surface 100 along its center; the fixed slide rail 402c is also provided on the side of the receiving chamber 201, where the fixed slide rail is located. The axis of slide 402c points to the rotation center of the movable slide 402d. When the movable slide 402d connects to the fixed slides 402c on both sides, the translation arm 402b can translate along the fixed slides 402c and the movable slide 402d to adjust the position of the drill rod G. At the same time, the bottom of the translation arm 402b can rotate to adjust the orientation of the drill rod G. The telescopic arm 402e can extend and retract to adjust the position of the drill rod G more precisely. When the translation arm 402b is on the movable slide 402d, the movement of the translation arm 402b can be stopped first, and the movable slide 402d can be rotated and connected to another fixed slide 402c. In this way, the translation arm 402b can be transferred from the movable slide 402d to the fixed slide 402c, thereby getting closer to the receiving chamber 201, making it convenient to place the drill rod G into or remove it from the receiving chamber 201.

[0060] The two vertical walls of the receiving chamber 201 are arranged parallel to the length direction of the moving slide 402d and the fixed slide 402c, respectively. Preferably, the root box 200 is a grid-shaped box structure, and each grid is a receiving chamber 201 that can hold a drill rod G. The gripping member 401 can vertically place the gripped drill rod G into the grid of the root box 200.

[0061] For different grids on the top drive 300 and the standby box 200, the moving part 402 can move closer to or further away from the grid by adjusting the position of the translation arm 402b on the fixed slide rail 402c. Furthermore, it can move closer to or further away from the grid by adjusting the extension amount of the telescopic arm 402e. The rotating arm 402a can adjust the orientation of the gripper 401. When taking out the drill pipe G from the discharge pipe of the transversely discharged drill pipe G, no manual adjustment is required, which greatly improves the automation level and overall efficiency of drilling operations and reduces the dependence on manual operation.

[0062] The bottom of the 200 drill string box is placed directly or indirectly on the ground, avoiding the need for a two-tiered platform structure to store and operate the drill rod G. This results in minimal pressure on the drill platform surface, reducing the strength requirements of the drill platform and the load-bearing capacity requirements of the base. This indirectly reduces the size of the drilling rig, making the entire system components small and lightweight, facilitating rapid movement and relocation of the drilling rig. This is of great significance for geothermal well drilling in small urban areas and is more suitable for geothermal development with limited site area requirements.

[0063] For traditional drilling rigs, when not using a second-level platform, the drill pipe is typically laid flat on the ground in front of the rig. During lowering, workers must first move the drill pipe from the ground to the inclined slide, where a jack on the derrick lifts it upright, aligning it with the wellhead. The drill pipe is then connected to the drilling tools downhole, completing the lowering process. Pulling out the drill pipe involves the reverse process: each drill pipe must be lifted, disassembled, and placed on the ground. This procedure is complex, time-consuming, and takes up space next to the drilling rig.

[0064] If a two-tiered platform structure is adopted, the number of times the drill pipe is disassembled during the tripping process can be reduced, and multiple drill pipe sections can be directly arranged on the two-tiered platform device. However, this also increases the load on the derrick and drill platform base, requiring larger load-bearing modules, which naturally leads to an increase in the base area.

[0065] In use, our invention utilizes a stand box 200 to store the drill rod G, with the bottom of the stand box 200 in contact with the ground, preventing the weight of the drill rod G from pressing on the platform surface 100. This eliminates the need for a load-bearing module under the base, reducing the overall footprint of the drilling rig. Furthermore, the stand box 200 is fixed in the mounting position 101 on the platform surface 100, thus not occupying space next to the base, further reducing the overall space occupied by the device. Simultaneously, due to the presence of the gripping component 401 and the moving component 402 of the operating component 400, the placement and removal of the drill rod G do not require manual operation by workers, avoiding extensive adjustments to the position of the drill rod G, improving drilling efficiency, simplifying the process, and saving time.

[0066] Example 4, refer to Figures 1-5 , Figure 11 This is the fourth embodiment of the present invention, which is based on the previous embodiment.

[0067] The drilling rig also includes a detection unit 500, located at the end of the gripper 401, for positioning the drill rod G, top drive 300, and receiving chamber 201, and generating a first signal. The detection unit 500 is mounted on the gripper 401 and faces the same direction as the gripper 401a. The first signal contains information about the orientation of the drill rod G and the distance between the drill rod G and the gripper 401a, as well as the position information of the drill rod G, top drive 300, and receiving chamber 201. This information is obtained using methods including but not limited to photography and infrared ranging, and is ultimately transmitted to the control unit 600.

[0068] The drilling rig also includes a control unit 600 connected to the detection unit 500. The control unit 600 receives the first signal from the detection unit 500 and generates a first instruction after processing it. The control unit 600 processes the first signal obtained from the detection unit 500 and obtains information on the orientation of the drill rod G and the distance between the drill rod G and the gripper 401a. It also obtains the position information of the drill rod G, the top drive 300, and the receiving chamber 201. Then, based on this information, the control unit 600 generates a specific action instruction, namely the first instruction, and transmits it to the execution unit 700 to control the movement of the gripper 401 and the moving part 402, thereby completing the work of gripping, transporting, and storing the drill rod G.

[0069] The drilling rig also includes an execution unit 700, which is connected to the control unit 600 and receives first instructions from the control unit 600 to drive the gripper 401 and the moving member 402 to move. The execution unit 700 is connected to the gripper 401 and controls the movement of the gripper 401 and the moving member 402, including the loosening and tightening of the gripper 401a, the rotation angle of the rotating arm 402a, the height of the translation arm 402b on the moving member 402, and the extension of the telescopic arm 402e.

[0070] The execution unit 700 is also connected to the movable member 402 and controls the movement of the translation arm 402b and the rotation of the movable slide 402d, thereby adjusting the position and orientation of the movable member 402. The execution unit 700 adjusts the state and position of the gripper 401 and the movable member 402 according to the first command transmitted by the control unit 600.

[0071] In use, when the control unit 600 issues commands such as drilling the drill pipe onto the drill platform, assisting in drilling, assisting in tripping the drill string, and storing the drill pipe, the control unit 600 uses the detection unit 500 to detect the first signal, processes it, generates the first command, and transmits it to the execution unit 700 to complete the first command. During this period, the detection unit 500 continues to detect and transmit data, and the control unit 600 continues to process and send commands, so that the system is in a cyclic feedback loop to correct any deviations that the execution unit 700 may produce when executing commands.

[0072] In this way, the pipe laying system can identify the positions of drill pipe G, top drive 300, and storage chamber 201, and complete the operations of grabbing, transporting, and storing drill pipe G, which greatly reduces the complexity of manual operation, reduces reliance on operators, and significantly improves the overall efficiency of drilling work and the working environment.

[0073] Example 5, refer to Figures 1-3 This is the fifth embodiment of the present invention, which is based on the first embodiment and provides a method for installing a drill bench support box.

[0074] The drilling platform is set with only one drilling platform surface of 100, instead of the two-level platform setting of traditional drilling rigs. This avoids making the overall mass of the drilling platform too large, which would require higher load-bearing capacity and thus a larger installation area, making it unsuitable for the small site area requirements of geothermal development.

[0075] Since the traditional two-tier platform setup of the drilling rig is not used, the support box 200 needs to be installed in another location. In order to meet the requirements of the small site area, the support box 200 is set on the mounting position 101 on the drilling platform 100, and the lower end of the support box 200 is lower than the lower surface of the drilling platform 100, so that the support box 200 rests directly or indirectly on the ground, avoiding the entire weight of the support box 200 pressing on the drilling platform 100.

[0076] The top drive 300 of the drilling rig is positioned horizontally on one side of a virtual dividing line X passing through the geometric center of the drilling rig surface 100. One side of the drilling rig surface 100 bears the mass of the top drive 300, while the mounting position 101 is positioned horizontally on the other side of the virtual dividing line X. This allows the other side of the drilling rig surface 100 to bear part of the mass of the stand box 200 and the drill pipe G, thus balancing the center of gravity of the drilling rig surface 100. The weight and applied force of the wellhead H and the top drive 300 are concentrated on one side, while the mounting position 101 and the stand box 200 are on the other side, enhancing the overall stability of the drilling rig, more rationally distributing its structural strength, and reducing the risk of overturning. Furthermore, the more drill pipe G stored in the stand box 200, the lower the risk of drilling rig overturning. Since the stand box 200 does not directly and completely press against the drilling rig surface 100, installing more drill pipe G in the stand box 200 will not increase the risk of drilling rig overturning.

[0077] Example 6, refer to Figures 7-10 This is the sixth embodiment of the present invention, which is based on the first embodiment and provides a pipe arrangement method.

[0078] The drive gripper 401 grips and lifts the drill rod from the pipe stack, placing it on the drilling platform. The drill rod G is transported via the pipe stack, which functions similarly to the riser box 200, but is located on the side of the drilling platform, eliminating the need for installation or standing, thus improving the efficiency of drill rod G usage. The execution unit 700 drives the moving part 402 to move horizontally to the side of the pipe stack and then rotates it, positioning the gripper 401 on top of the pipe stack. After the pipe stack cylinder lifts the drill rod to a predetermined height, the execution unit 700 drives the gripper 401 to slide down along the moving part 402 until the gripper 401 is aligned with the drill rod. Then, the execution unit 700 drives the gripper 401 to grip the drill rod and lift it vertically, removing the drill rod from the pipe stack and preventing it from contacting the drilling platform.

[0079] Next, the execution unit 700 drives the gripper 401 to rotate, adjusting the drill rod G from horizontal to vertical. Then, the execution unit 700 drives the moving part 402 to move horizontally to the bottom of the top drive 300. Next, the execution unit 700 drives the gripper 401 to connect the drill rod G to the top drive 300, assisting in drilling. The drill rod G consists of a male connector, a female connector, and a tube body. After the first drill rod G is lowered to a certain depth by the top drive 300, the female connector of the first drill rod G is exposed, and the male connector of the second drill rod G is threaded together. Then, the top drive connects to the top of the second drill rod G, thus completing the drilling process.

[0080] When it is necessary to remove the drill pipe G, the top drive 300 lifts the drill pipe G to the wellhead. The execution unit 700 drives the moving part 402 to move to the side of the top drive and face the top drive. The execution unit 700 drives the gripping part 401 to grip the drill pipe. After the top drive 300 separates the drill pipe G, the drill pipe G is then moved away.

[0081] After the drill rod G and the top drive 300 separate, the top drive 300 rises, and then the moving part 402 moves to one side of the receiving chamber 201. The gripping part 401 is raised to prevent the drill rod G from contacting the drill table. The gripping part 401 flips so that the drill rod G faces the receiving chamber 201. The moving part 402 moves to align the drill rod G with one of the grids in the receiving chamber 201. The gripping part 401 is then driven to lower the drill rod G and place it into the receiving chamber 201.

[0082] More detailed, such as Figure 10 , Figure 11 First, drive the gripper 401 to raise the drill rod G; second, rotate the gripper 401 half a turn along the end of the gripper 401 so that the drill rod G rotates to the other side of the moving part 402; third, drive the moving part 402 so that the drill rod G is aligned with the receiving chamber 201; fourth, drive the gripper 401 to descend along the moving part 402 and place the drill rod G into the receiving chamber 201.

[0083] During operation, the gripper 401 automatically and precisely grabs and lifts the drill pipe during the process of grabbing it onto the drilling platform, reducing manual labor and improving work efficiency. During the drilling process, the gripper 401 completes the drill pipe docking directly below the top drive, ensuring precision and efficiency, reducing potential deviations during manual docking, and further improving work efficiency. During the tripping process, the gripper 401 grabs and separates from the top drive, reducing the risks associated with manual operation and improving safety. When storing the drill pipe in the riser box, the design, which eliminates the second-tier platform structure and uses the riser box, saves space, making it particularly suitable for geothermal drilling operations in confined urban areas. This reduces the intensity of manual handling and further improves site utilization and work efficiency.
