[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] Secondly, the term "one 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 term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0037] Example 1, reference Figure 1 ~ Figure 5 , which is the first embodiment of the present invention, provides a drilling platform, including a drilling platform 100 and one or more stand boxes 200. The drilling platform 100 is supported by a supporting structure at the bottom, and is arranged in parallel at a certain height from the ground to form a stable working platform, which is the main bearing structure of the drilling platform. Preferably, the drilling platform 100 is rectangular, which is convenient for arranging the installation position 101 and other auxiliary equipment, and is convenient for docking and arranging with surrounding equipment.

[0038] The drilling table 100 is provided with a mounting position 101 for accommodating and fixing the root box 200, and the drilling table 100 with the root box 200 fixed thereon also improves the stability of the drilling table as a whole; preferably, the mounting position 101 is a rectangular groove, which is arranged on an edge of the drilling table 100, wherein one edge of the mounting position 101 coincides with an edge of the drilling table 100, and the other edges of the mounting position 101 and the edges of the drilling table 100 are either parallel or perpendicular, so as to facilitate the positioning of the root box 200 during installation and the processing of the mounting position 101; the number of the mounting positions 101 and the root box 200 is the same and corresponds one to one.

[0039] Furthermore, the installation positions 101 are evenly and symmetrically distributed in the horizontal direction on the drilling floor 100 , and each stand box 200 is independent of each other. When the stand boxes 200 are installed or removed from the installation positions 101 , they will not affect each other.

[0040] The shape of the stand box 200 matches the shape of the mounting position 101, and the stand box 200 can be installed and fixed on the mounting position 101 when in use, and can also be disassembled from the mounting position 101 when not in use; the top of the stand box 200 protrudes from the drilling table 100, which is convenient for storing and taking out the drill rods G; the lower end of the stand box 200 is lower than the lower surface of the drilling table 100, ensuring that the weight of the stand box 200 is not completely pressed on the drilling table 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 drilling table 100; at the same time, after the stand box 200 is installed on the mounting position 101, it can provide certain support for the drilling table 100, and the more drill rods G are stored in the stand box 200, the stronger the support provided for the drilling table 100.

[0041] The placement method of the root box 200 reduces the support strength required for the drilling platform 100, which can ensure that the support strength of the drilling platform of the present invention is reduced due to the reduced size, while the weight of other components can be reasonably distributed, so that the strength and stability of the drilling platform can be guaranteed in a smaller area.

[0042] The design of the root box 200 makes the overall volume of the drilling platform smaller, which is more suitable for the requirements of geothermal development on small site areas.

[0043] Preferably, the storage bins 201 are periodically and densely laid in the root box 200, and the opening is set on the top surface of the root box 200 to facilitate the storage and removal of the drill rods G; each storage bin 201 can accommodate a drill rod G, and each storage bin 201 is independent of each other, ensuring that the drill rods G will not interfere with each other when storing and taking out the drill rods G.

[0044] Among them, a cylinder is provided at the bottom of each storage bin 201, which can push out the drill rod G to facilitate the storage and retrieval of the drill rod G.

[0045] When in use, the pipe box 200 is installed on the installation position 101 of the drilling floor 100, so that the top of the pipe box 200 protrudes from the drilling floor 100, and the bottom of the pipe box 200 is in direct or indirect contact with the ground, so as to avoid that all or most of the weight of the pipe box 200 is borne by the drilling floor 100. Such a pipe box 200 can be installed on a reduced drilling floor. When the overall volume of the drilling floor is reduced and the bearing capacity is reduced, no additional pressure is added to the drilling floor 100, and a position for storing and taking the drill rods G is provided, and the overall stability of the drilling floor is improved. The storage compartment 201 provided on the pipe 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 facilitating the taking of the drill rods G.

[0046] When the pipe box 200 is fixed on the installation position 101 of the drilling floor 100, the bottom of the pipe box 200 directly or indirectly contacts the ground, and does not press its own weight on the drilling floor 100, which not only reduces the burden on the drilling floor 100, but also provides certain support for the drilling floor 100. After the accommodating chamber 201 accommodates the drill rod G, the mass of the pipe box 200 increases, which further improves the overturning resistance of the drilling floor 100.

[0047] This embodiment achieves stable fixation and reasonable layout of the root box 200 by setting a rectangular groove installation position 101 matching the root box 200 on the rectangular drilling table 100. The root box 200 adopts a detachable design, and a mounting position 101 is provided on the top to facilitate the placement of the drill rod G. The lower end is in direct or indirect contact with the ground to reduce the pressure on the drilling table 100, thereby ensuring that the drilling table can still remain stable when the supporting capacity of the ground is reduced; at the same time, the dense distribution of the storage bin 201 optimizes the storage space of the drill rod G. This design scheme reduces the area of ​​the drilling table, making it more suitable for the city, without reducing the stability of the drilling table and the carrying capacity of the drill rod G. It also enhances the space utilization and structural stability of the drilling table, provides more flexible operation options, and can meet the diverse needs of actual drilling operations.

[0048] Example 2, reference Figure 1 to Figure 6 , which is the second embodiment of the present invention, and is different from the first embodiment in that: the installation position 101 is a right-angled trapezoidal groove, and there are multiple of them, which are symmetrically arranged on one side of the drilling table 100, wherein the oblique side of the installation position 101 coincides with one side of the drilling table 100, which is convenient for the installation and removal of the root box 200, and the distance between the top and bottom sides of the installation position 101 is matched with the width of the root box 200; the non-oblique side of the installation position 101 and the side of the drilling table 100 are not parallel or perpendicular, which is convenient for improving the anti-overturning ability of the drilling table 100.

[0049] When in use, the pipe box 200 is installed on the installation position 101 of the drilling floor 100, so that the top of the pipe box 200 protrudes from the drilling floor 100, and the bottom of the pipe box 200 is in direct or indirect contact with the ground, so as to avoid that the weight of the pipe box 200 is borne entirely or mostly by the drilling floor 100. Such a pipe box 200 can be installed on a reduced drilling floor. When the overall volume of the drilling floor is reduced and the bearing capacity is reduced, no additional pressure is added to the drilling floor 100, and a position for storing and taking out the drill rods G is provided, thereby improving the overall stability of the drilling floor. The storage compartment 20 After accommodating the drill rod G, the mass of the stand box 200 increases, which can also improve the overturning resistance of the drilling floor 100. At the same time, since the installation position 101 is a right-angled trapezoidal groove, the edge of the stand box 200 fits the edge of the installation position 101, but the edge of the stand box 200 is not parallel to the edge of the drilling floor 100. In case the drilling floor 100 tends to overturn due to excessive wind force or earthquakes and other unexpected factors, the edge of the stand box 200 is not parallel to the edge of the drilling floor 100. Therefore, the existence of the stand box 200 will prevent the drilling floor 100 from overturning, and further improve the overturning resistance of the drilling floor 100.

[0050] The storage compartment 201 provided on the vertical root box 200 can accommodate a single drill rod G, ensuring that there is a certain distance between multiple drill rods G, so that they do not interfere with each other, and it is convenient to take the drill rods G. While the vertical root box 200 slowly accommodates the drill rods G, it also improves the support strength of the drilling table 100 and improves the overturning resistance of the drilling table. When the vertical root box 200 is fixed on the installation position 101 of the drilling table 100, the bottom of the vertical root box 200 directly or indirectly contacts the ground, and does not press its own weight on the drilling table 100, which not only reduces the burden on the drilling table 100, but also provides certain support for the drilling table 100. After the storage compartment 201 accommodates the drill rods G, the mass of the vertical root box 200 increases, which further improves the overturning resistance of the drilling table 100.

[0051] In this embodiment, a right-angled trapezoidal groove installation position 101 matching the root box 200 is provided on the rectangular drilling table 100, so as to achieve stable installation and reasonable layout of the root box 200. The root box 200 adopts a detachable design, and a mounting position 101 is provided on the top to facilitate the placement of the drill rod G. The lower end is in direct or indirect contact with the ground to reduce the pressure on the drilling table 100, so as to ensure that the drilling table can still remain stable when the supporting capacity is reduced due to the reduction of the overall volume and floor area of ​​the drilling table; at the same time, the close distribution of the storage bin 201 optimizes the storage space of the drill rod G, and while ensuring the capacity of the root box 200 to store the drill rod G, a certain distance is allowed between the drill rods G, so as to avoid mutual interference between the drill rods G during storage and retrieval. This design scheme reduces the area of ​​the drilling table, making it more suitable for the city, without reducing the stability of the drilling table and the carrying capacity of the drill rod G. It also enhances the space utilization and structural stability of the drilling table, provides more flexible operation options, and can meet the diverse needs in actual drilling operations.

[0052] Example 3, reference Figure 1 to Figure 10 , which is the third embodiment of the present invention, and is based on the first embodiment.

[0053] The drilling floor 100 is provided with an installation position 101 and a drilling port H. The drilling floor 100 bears the weight of various drilling equipment, supports the installation and operation of the equipment, and provides a working space. The drilling port H is located on the side of the drilling floor 100 that deviates from the center of the drilling floor 100 and is used to move the drill pipe G up and down. The top drive 300 is located at the top of the drilling port H and is used to connect the drill pipe G and provide power to the drill pipe G so as to adjust the position of the drill pipe G. The drilling port H is located in the horizontal direction at the middle of a virtual dividing line X passing through the geometric center of the drilling floor 100. On one side; the installation position 101 is located on the other side of the virtual dividing line X in the horizontal direction. Since a top drive 300 is provided on the top of the wellbore H and a stand box 200 is installed on the installation position 101, such a layout can effectively balance the center of gravity of the drilling floor 100; the weight and applied force of the wellbore H and the top drive 300 are concentrated on one side, while the installation position 101 and the stand box 200 are on the other side, forming a lever effect, thereby enhancing the overall stability of the drilling floor, more reasonably distributing the structural strength of the drilling floor, and reducing the risk of overturning.

[0054] At the same time, the drilling port H is set separately from the installation position 101, which optimizes the operation process. During the drilling operation, the operator can more conveniently take and store the drill pipe G from one side without interfering with the drilling operation. The space utilization rate is improved, and the top drive 300 and the root box 200 are staggered, which reduces the interference to the operating personnel at work and improves the operation efficiency. The flexibility of the drilling platform is increased, and the space outside the drilling port H and the installation position 101 on the drilling platform surface 100 is used to place parts such as motors or operating tables.

[0055] The installation position 101 is directly opened on the drilling table 100, so that the bottom of the root box 200 can be placed directly or indirectly on the ground. Therefore, there is no need to set a two-story platform for storing drill rods on the drilling table 100, but the top of the root box 200 directly cooperates with the installation position 101; and because the root box 200 no longer puts all the weight on the drilling table 100, the support assembly under the drilling table 100 can also be reduced in size and strength, so that the overall footprint of the entire device can be reduced while maintaining the stability of the device; at the same time, the root box 200 is directly placed in the installation position 101, rather than being installed next to the drilling table 100, which also reduces the footprint; the drill rod G can be taken in and put in more quickly and conveniently through the root box 200, and such a drilling table is more suitable for places with smaller construction sites, such as inside cities.

[0056] Specifically, the operating component 400 includes a gripping member 401, which is used to grip and release the drill rod G; the gripping member 401 includes a gripper 401a, which is composed of one or more coaxially arranged grippers 401a, and is used 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 with each other and are sufficiently far apart from each other, so as to improve the stability when holding the drill rod G while reducing the difficulty of operation.

[0057] The operating component 400 also includes a moving part 402 for adjusting the position of the grabbing part 401. The moving part 402 is arranged at the end of the grabbing part 401, which includes a rotating arm 402a and a telescopic arm 402e. The grabbing part 401 cooperates with the rotating arm 402a through the telescopic arm 402e. The telescopic arm 402e can adjust the distance from the grabbing part 401 to the rotating arm 402a. The rotating arm 402a can adjust the direction of the grabbing part 401 to facilitate the grabbing and placement of drill rods at different angles.

[0058] The drill pipe G is a component used in drilling operations to transmit rotational power and downward force. It consists of a male joint, a female joint, and a pipe body. The female joint of the first drill pipe is threaded together with the male joint of the next drill pipe. The pipe rack is a device used to store and manage drill pipes. It is placed on the side of the drilling platform to facilitate the robot to grab it, thereby reducing the workload of manual operation. 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 installed above the derrick of the drilling rig. The wellhead H is directly below the top drive 300. The top drive drills the drill pipe G into the well through the wellhead H or pulls the drill pipe G out through the wellhead H.

[0059] The moving member 402 also includes a translation arm 402b, a fixed slide 402c and a movable slide 402d; one end of the rotating arm 402a is matched with the translation arm 402b and can move on the translation arm 402b; the translation arm 402b is preferably a column perpendicular to the drilling floor, and the bottom is matched with the fixed slide 402c and the movable slide 402d, and the translation arm 402b can be translated along the fixed slide 402c and the movable slide 402d, and can also rotate along the bottom axis of the translation arm 402b; the fixed slide 402c is fixed to the top of the drilling floor 100 and is arranged between the drilling port H and the root box 200; a movable slide 402d is arranged between the two fixed slides 402c, and the movable slide 402d can rotate on the drilling floor 100 along its center; the fixed slide 402c is also arranged on the side of the accommodating bin 201, and the fixed slide therein The axis of the slide 402c points to the rotation center of the movable slide 402d; when the movable slide 402d is connected to the fixed slides 402c on both sides, the translation arm 402b can be translated along the fixed slide 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 be rotated to adjust the direction of the position of the drill rod G, and the telescopic arm 402e can be telescopic to more finely adjust the position of the drill rod G; 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 docked with another fixed slide 402c, so that the translation arm 402b can be transferred from the movable slide 402d to the fixed slide 402c, thereby approaching the accommodating bin 201, making it convenient to place the drill rod G in the accommodating bin 201 or take it out from the accommodating bin 201.

[0060] The two vertical walls of the storage bin 201 are respectively arranged parallel to the length direction of the movable slide 402d and the fixed slide 402c; preferably, the root box 200 is a grid-shaped box structure, each grid is a storage bin 201, which can accommodate a drill rod G, and the grabbing member 401 can vertically place the grabbed drill rod G into the grid of the root box 200.

[0061] For different grids on the top drive 300 and the stand box 200, the moving part 402 can be moved closer to or farther away from the grid by adjusting the position of the translation arm 402b on the fixed slide 402c. Furthermore, the moving part 402 can be moved closer to or farther away from the grid by adjusting the telescopic amount of the telescopic arm 402e, and the rotating arm 402a can adjust the direction of the grabbing part 401. No manual adjustment is required when taking out the drill pipe G from the storage pipe for horizontally discharging the drill pipe G, which greatly improves the degree of automation and overall efficiency of drilling operations and reduces dependence on manual operations.

[0062] The bottom of the root box 200 is placed directly or indirectly on the ground, avoiding the use of a two-layer platform structure to store and operate the drill rod G. The pressure on the drilling table is extremely small, which reduces the strength requirement of the drilling table and the bearing capacity requirement of the base, and indirectly reduces the size of the drilling rig, making the entire system components small and light, and easy to achieve rapid movement and relocation of the drilling rig. It is of great significance for the drilling of geothermal wells in small sites in cities, and is more suitable for geothermal development with smaller site area requirements.

[0063] For traditional drilling rigs, when the two-story platform device is not used, the drill pipe is usually laid flat on the ground in front of the drilling rig. When drilling, workers need to move the drill pipe from the ground to the inclined slideway first, and then the elevator on the derrick lifts the drill pipe so that the drill pipe is upright and aligned with the wellhead, and then the drill pipe is connected to the drilling tool in the well to complete the drilling. When pulling out the drill, the process is reversed, and the drill pipes need to be lifted one by one, disassembled and placed on the ground. This process is complicated, time-consuming, and takes up space next to the drilling rig.

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

[0065] During use, we invented the use of a pipe box 200 to store the drill rod G, and the bottom of the pipe box 200 is in contact with the ground, so that the weight of the drill rod G is not pressed on the platform surface 100, so there is no need to increase the load-bearing module under the base, and the overall footprint of the drilling rig is small; and the pipe box 200 is still fixed in the installation position 101 on the platform surface 100, so it will not occupy the space next to the base, further reducing the overall footprint of the device; at the same time, due to the presence of the grabbing part 401 and the moving part 402 of the operating component 400, the drill rod G does not need to be manually operated by the worker to take and put, which avoids the need to adjust the position of the drill rod G over a large range, improves the efficiency of drilling up and down, simplifies the process, and saves time.

[0066] Example 4, reference Figure 1~Figure 5 , Fig.11 , which is the fourth embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0067] The drilling platform also includes a detection unit 500, which is arranged at the end of the gripper 401, and is used to locate the drill pipe G, the top drive 300 and the storage chamber 201, and generate a first signal. The detection unit 500 is installed on the gripper 401 and faces the same direction as the gripper 401a. The first signal contains information about the direction of the drill pipe G and the distance between the drill pipe G and the gripper 401a, and also includes the position information of the drill pipe G, the top drive 300 and the storage chamber 201, which is obtained by methods including but not limited to taking pictures, infrared ranging, etc., and finally transmitted to the control unit 600.

[0068] The drilling platform also includes a control unit 600, which is connected to the detection unit 500, receives the first signal from the detection unit 500, and generates a first instruction after processing. The control unit 600 processes the first signal obtained from the detection unit 500 and obtains information about the direction of the drill pipe G and the distance between the drill pipe G and the gripper 401a, and also obtains the position information of the drill pipe G, the top drive 300 and the storage chamber 201. Then, the control unit 600 generates a specific action instruction, that is, the first instruction, based on this information and transmits it to the execution unit 700 to control the movement of the gripping member 401 and the moving member 402, thereby completing the work of gripping, transporting and storing the drill pipe G.

[0069] The drilling platform also includes an execution unit 700, which is connected to the control unit 600, receives a first instruction from the control unit 600, and drives the grabbing member 401 and the moving member 402 to move. The execution unit 700 is connected to the grabbing member 401 and controls the movement of the grabbing member 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 moving member 402 and controls the movement of the translation arm 402b and the rotation of the moving slide 402d, thereby adjusting the position and orientation of the moving member 402. The execution unit 700 adjusts the state and position of the grabbing member 401 and the moving member 402 according to the first instruction transmitted by the control unit 600.

[0071] When in use, when the control unit 600 issues instructions such as putting the drill rod on the drilling platform, assisting in drilling, assisting in pulling out the drill and storing the drill rod, the control unit 600 uses the detection unit 500 to detect the first signal, generates a first instruction after processing, passes it to the execution unit 700 and allows the execution unit 700 to complete the first instruction; during this period, the detection unit 500 keeps detecting and transmitting data, and the control unit 600 keeps processing and sending instructions, so that the system is in a loop feedback to correct the deviations that may occur when the execution unit 700 executes the instructions.

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

[0073] Example 5, reference Figure 1~Figure 3 , which is the fifth embodiment of the present invention, is based on the first embodiment and provides a method for installing a drilling platform root box.

[0074] The drilling platform is only provided with one drilling platform surface 100, instead of adopting the two-layer platform setting of the traditional drilling rig, so as to avoid making the overall mass of the drilling platform too large, resulting in the need for higher bearing capacity, and thus requiring a larger installation area, which is not suitable for the demand for small site area conditions for geothermal development.

[0075] Since the two-layer platform of the traditional drilling rig is not adopted, the root box 200 needs to be installed at other positions. In order to meet the requirements of the small site area, the root box 200 is set on the installation position 101 on the drilling floor 100, and the lower end of the root box 200 is lower than the lower surface of the drilling floor 100, so that the root box 200 falls on the ground directly or indirectly, avoiding the weight of the root box 200 from being fully pressed on the drilling floor 100.

[0076] The top drive 300 of the drilling platform is horizontally arranged on one side of a virtual dividing line X passing through the geometric center of the drilling platform 100, so that one side of the drilling platform 100 bears the mass of the top drive 300, and the installation position 101 is arranged on the other side of the virtual dividing line X in the horizontal direction, so that the other side of the drilling platform 100 bears part of the mass of the root box 200 and the drill pipe G, so that the center of gravity of the drilling platform 100 can be balanced; the weight and applied force of the wellbore H and the top drive 300 are concentrated on one side, while the installation position 101 and the root box 200 are on the other side, which enhances the overall stability of the drilling platform, more reasonably distributes the structural strength of the drilling platform, and reduces the risk of overturning. In addition, the more drill pipes G are stored in the root box 200, the lower the risk of overturning of the drilling platform. At the same time, since the root box 200 is not directly and completely pressed on the drilling platform 100, the root box 200 will not increase the risk of overturning of the drilling platform even if more drill pipes G are installed.

[0077] Example 6, reference Figure 7~Figure 10 , which is the sixth embodiment of the present invention, provides a pipe arrangement method based on the first embodiment.

[0078] The grabbing member 401 is driven to grab the drill rod lifted by the pipe arrangement bin and lift it up to put the drill rod on the drilling platform. The drill rod G is transported by the pipe arrangement bin. The function of the pipe arrangement bin is similar to that of the root box 200. However, the pipe arrangement bin is set on the side of the drilling platform and does not need to be installed or stood up, which can improve the use efficiency of the drill rod G. The execution unit 700 drives the moving member 402 to move horizontally to one side of the pipe arrangement bin and turns to the pipe arrangement bin so that the grabbing member 401 is at the top of the pipe arrangement bin. After the pipe arrangement bin oil cylinder lifts the drill rod to a predetermined height, the execution unit 700 drives the grabbing member 401 to slide down along the moving member 402 until the grabbing member 401 is aligned with the drill rod. Then the execution unit 700 drives the grabbing member 401 to grab the drill rod and lift it vertically to take the drill rod out of the pipe arrangement bin and avoid the contact between the drill rod and the drilling platform.

[0079] Then the execution unit 700 drives the grabbing member 401 to rotate, so that the drill pipe G is adjusted from horizontal to vertical, and then the execution unit 700 drives the moving member 402 to move the moving member 402 to the bottom of the top drive 300, and then the execution unit 700 drives the grabbing member 401 to connect the drill pipe G to the top drive 300 to assist in drilling. The drill pipe G is composed of a male joint, a female joint, and a pipe body. When the first drill pipe G is lowered to a certain depth by the top drive 300, the female joint of the first drill pipe G is exposed and threadedly connected to the male joint of the second drill pipe G, and then the top drive is connected to the top of the second drill pipe G, so that drilling is completed.

[0080] When the drill pipe G needs to be taken out, the top drive 300 drives the drill pipe G to be lifted to the drilling port, the execution unit 700 drives the moving part 402 to move to one side of the top drive and face the top drive, the execution unit 700 drives the grabbing part 401 to grab the drill pipe, and after the top drive 300 separates the drill pipe G, the drill pipe G is then moved away.

[0081] After the drill pipe G and the top drive 300 are separated, the top drive 300 rises, and then the moving part 402 moves to the side of the accommodating chamber 201, the grabbing part 401 is raised to prevent the drill pipe G from contacting the drilling platform, and the grabbing part 401 is flipped so that the drill pipe G faces the side of the accommodating chamber 201. The moving part 402 moves to align the drill pipe G with one of the grids of the accommodating chamber 201, and drives the grabbing part 401 to drop the drill pipe G and place it in the accommodating chamber 201.

[0082] More detailed, such as Fig.10 , Fig.11 The first step is to drive the grabbing member 401 to lift the drill rod G; the second step is to rotate the grabbing member 401 half a circle along the end of the grabbing member 401 to rotate the drill rod G to the other side of the moving member 402; the third step is to drive the moving member 402 to align the drill rod G with the accommodating chamber 201; the fourth step is to drive the grabbing member 401 to descend along the moving member 402 and place the drill rod G into the accommodating chamber 201.

[0083] When in use, in the process of grabbing the drill pipe and going onto the drilling platform, the drill pipe is grabbed and lifted by the grabbing piece 401, and the operation is automated and precise, which reduces manual operation and improves working efficiency; in the process of assisting in drilling, the grabbing piece 401 completes the docking of the drill pipe just below the top drive, which is precise and efficient, reduces the deviation that may occur during the manual docking process, and further improves working efficiency; in the process of assisting in drilling, the grabbing piece 401 grabs and completes the separation from the top drive, which reduces the danger of manual operation by workers and improves safety; in the process of storing the drill pipe in the root box, the design of eliminating the two-story platform structure and installing the root box saves site space, which is particularly suitable for geothermal drilling operations in small urban sites, reduces the intensity of manual handling, and further improves site utilization and working efficiency.
