Description

Technical Field

[0001] This invention relates to the field of connection equipment technology, and more specifically, to a connection platform. Background Technology

[0002] In the field of vertical shaft construction, drilling with vertical shaft drilling rigs is a construction method characterized by high overall efficiency, low safety risk, good well quality, and wide applicability. Drill pipe consists of the drill pipe to be installed and drill pipe sections. As the drilling depth increases, the drill pipe to be installed needs to be divided into drill pipe sections to adjust the overall length of the drill pipe to match the drilling depth.

[0003] In related technologies, a robotic arm suspended on the drill rig is used to transfer drill rod segments from the docking platform to the drill rod to be installed. The robotic arm then assembles the drill rod segments onto the drill rod to complete the drill rod extension and installation operation. Since the optimal force application point for each drill rod segment is near its midpoint along its length, the robotic arm needs to move up and down to grasp the midpoint of different length segments when clamping them, which increases the requirements for the robotic arm's vertical travel.

[0004] Thus, when the robotic arm is gripping rod-shaped parts of different lengths, the requirements for the vertical travel of the robotic arm are relatively high, which increases the cost of the robotic arm and the construction cost. Summary of the Invention

[0005] The main objective of this invention is to provide a docking platform to solve the problem in related technologies where the robot arm has high requirements for its vertical travel when gripping rod-shaped parts of different lengths.

[0006] To achieve the above objectives, the present invention provides a connecting platform for connecting rod-shaped parts. The connecting platform includes: a base; a positioning post disposed on the base, the positioning post extending into the rod-shaped part and positioning and engaging with the rod-shaped part; and a lifting plate disposed on the base in a height-adjustable manner, the lifting plate being sleeved outside the positioning post and used to support the rod-shaped part, the lifting plate being able to drive the rod-shaped part to rise and fall when it rises and falls.

[0007] Furthermore, the positioning post includes a post body and a first positioning rib disposed on the outer side wall of the post body. The first positioning rib extends along the axial direction of the post body. There are multiple first positioning ribs, which are spaced apart along the circumference of the post body. The top of the first positioning rib is provided with a first guide slope, which gradually moves away from the outer side wall of the post body in the direction from top to bottom.

[0008] Furthermore, the lifting plate is provided with mounting holes for the positioning posts, and the connecting platform also includes a second positioning rib provided on the upper surface of the lifting plate. The second positioning rib extends along the lifting direction of the lifting plate. There are multiple second positioning ribs, which are spaced apart on the outer side of the mounting hole. The second positioning rib can extend into the rod-shaped part. The top of the second positioning rib is provided with a second guide slope, which gradually moves away from the mounting hole in the direction from top to bottom.

[0009] Furthermore, the wall of the mounting hole mates with the outer wall of the column body. The wall of the mounting hole is provided with a receiving groove for accommodating the first positioning rib. There are multiple receiving grooves, which are spaced apart along the circumference of the mounting hole and are arranged one-to-one with the multiple first positioning ribs. The second positioning rib is arranged between two adjacent receiving grooves. The axis of the second positioning rib is perpendicular to the upper surface of the lifting plate, or the axis of the second positioning rib gradually approaches the center of the mounting hole from bottom to top.

[0010] Furthermore, the positioning post includes a post body and a guide cone protruding from the top of the post body, the outer side wall of the guide cone gradually moving away from the axis of the guide cone in the direction from top to bottom.

[0011] Furthermore, the guide cone is vertically and flexibly disposed within the positioning column, and the docking platform also includes a first driving member disposed within the positioning column. The first driving member drives the guide cone to rise and fall, so that the guide cone has a guiding position protruding from the top of the column body and a retracted avoidance position within the positioning column.

[0012] Furthermore, the docking platform also includes an extension column disposed within the positioning column. The extension column is connected to the bottom of the guide cone. The first driving component drives the extension column to rise and fall, thereby driving the guide cone to rise and fall. The extension column has an extension position protruding from the top of the column body and a retracted position retracted into the positioning column.

[0013] Furthermore, the base includes a base plate, a support plate disposed above the base plate, and a support column connecting the base plate and the support plate. The support plate is located below the lifting plate, and the lifting plate can descend to a position supported by the support plate. The connecting platform also includes a second driving component that drives the lifting plate to move up and down. One end of the second driving component is connected to the base plate, and the other end of the second driving component is connected to the lifting plate. The second driving component passes through the support plate, and the support plate is provided with a through hole to avoid the second driving component.

[0014] Furthermore, the docking platform also includes elastic buffers, which are disposed between the support plate and the lifting plate. There are multiple elastic buffers, which are spaced apart along the circumference of the positioning column.

[0015] Furthermore, the first positioning rib includes an upper rib and a lower rib. The lower rib is located at the bottom of the first positioning rib, and the upper rib is connected above the lower rib. The first guide slope is set at the top of the upper rib. The upper rib is a rigid member, and the maximum distance between the outer surface of the upper rib and the column body remains unchanged. The lower rib is an elastic member, and the maximum distance between the outer surface of the lower rib and the column body gradually increases from top to bottom. The elastic member can be interference-fitted with the rod-shaped part.

[0016] According to the technical solution of this invention, a docking platform is used to dock rod-shaped parts. The docking platform includes a base, a positioning column, and a lifting plate. The positioning column is disposed on the base, extends into the rod-shaped part, and engages with it for positioning. The lifting plate is movably disposed on the base, sleeved over the positioning column, and supports the rod-shaped part. The lifting plate's movement during lifting causes the rod-shaped part to move up and down. The base stably supports the positioning column, which positions the rod-shaped part, ensuring it is stably placed on the docking platform. This reduces the possibility of the rod-shaped part tipping over during lifting, improving the safety and stability of the docking platform when docking rod-shaped parts. The lifting plate's ability to move the rod-shaped part up and down allows for adjustable height of rod-shaped parts of different lengths relative to the robotic arm, and also allows for adjustable height of the midpoint of the rod-shaped part relative to the robotic arm along its length. In this way, by adjusting the height of the rod-shaped part, the midpoint of the rod-shaped part can be adjusted. The position of the midpoint of the rod-shaped part can be adjusted within the vertical travel range of the robot arm by raising and lowering the lifting plate, thereby reducing the requirements for the vertical travel range of the robot arm and reducing the cost of the robot arm and construction. Therefore, the technical solution of this application effectively solves the problem in related technologies where the vertical travel requirements of the robot arm are high when gripping rod-shaped parts of different lengths.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0037] like Figures 1 to 3 As shown, the connecting platform in this embodiment is used to connect rod-shaped parts. The connecting platform includes a base 10, a positioning post 20, and a lifting plate 30. The positioning post 20 is disposed on the base 10, extends into the rod-shaped part, and is positioned and engaged with the rod-shaped part. The lifting plate 30 is movably disposed on the base 10, sleeved on the outside of the positioning post 20, and is used to support the rod-shaped part. When the lifting plate 30 is raised or lowered, it can drive the rod-shaped part to rise or fall.

[0038] Using the technical solution of Embodiment 1, the docking platform is used to dock rod-shaped parts. The docking platform includes a base 10, a positioning post 20, and a lifting plate 30. The positioning post 20 is disposed on the base 10, extends into the rod-shaped part, and is positioned and engaged with the rod-shaped part. The lifting plate 30 is movably disposed on the base 10, sleeved outside the positioning post 20, and used to support the rod-shaped part. When the lifting plate 30 is raised or lowered, it can drive the rod-shaped part to rise or fall. The base 10 can stably support the positioning post 20, and the positioning post 20 can position the rod-shaped part, so that the rod-shaped part can be stably placed on the docking platform, reducing the possibility of the rod-shaped part tipping over when it is raised or lowered on the lifting plate 30, and improving the safety and stability of the docking platform when docking rod-shaped parts. The lifting plate 30 can drive the rod-shaped part to rise or fall, so that the height of rod-shaped parts of different lengths relative to the robot arm is adjustable, and the height of the midpoint of the rod-shaped part in its length direction relative to the robot arm is adjustable. In this way, by adjusting the height of the rod-shaped part, the midpoint of the rod-shaped part can be adjusted. The position of the midpoint of the rod-shaped part can be adjusted within the vertical travel range of the robot arm by raising and lowering the lifting plate 30, thereby reducing the requirements for the vertical travel range of the robot arm and reducing the cost of the robot arm and construction. Therefore, the technical solution of Embodiment 1 effectively solves the problem in related technologies where the vertical travel requirements of the robot arm are high when gripping rod-shaped parts of different lengths.

[0039] like Figures 1 to 3 As shown, in Embodiment 1, the positioning post 20 includes a post body 21 and a first positioning rib 23 disposed on the outer side wall of the post body 21. When the rod-shaped part is sleeved on the positioning post 20, the first positioning rib 23 is located between the outer side wall of the post body 21 and the inner side wall of the rod-shaped part, filling the gap between the outer side wall of the post body 21 and the inner side wall of the rod-shaped part, so that the rod-shaped part can be stably sleeved on the positioning post 20. The first positioning rib 23 extends along the axial direction of the post body 21, and there are multiple first positioning ribs 23, which are spaced apart circumferentially along the post body 21. The arrangement of multiple first positioning ribs 23 further enables the rod-shaped part to be stably sleeved on the positioning post 20 and makes the force on the rod-shaped part more uniform. The top end of the first positioning rib 23 is provided with a first guide slope 24, which gradually moves away from the outer side wall of the post body 21 in the direction from top to bottom. The first guide ramp 24 can guide and cooperate with the end of the rod-shaped part so that the end of the rod-shaped part can smoothly pass through the first guide ramp 24 and be sleeved on the outside of the positioning post 20, thereby improving the efficiency of the rod-shaped part being sleeved on the outside of the positioning post 20.

[0040] In Embodiment 1, when the lifting plate 30 descends to its lowest point, the apex of the first positioning rib 23 is lower than the top surface of the positioning post 20 to avoid interfering with the rotation of the robotic arm after it grips the rod-shaped part.

[0041] like Figures 4 to 6 As shown, in Embodiment 2, a second positioning rib 31 is added based on Embodiment 1. The lifting plate 30 is provided with mounting holes 33 that pass through the positioning post 20. The mounting holes 33 can avoid the positioning post 20, allowing the lifting plate 30 to rise and fall outside the positioning post 20. The docking platform also includes a second positioning rib 31 provided on the upper surface of the lifting plate 30, which can rise and fall with the lifting plate 30. When the length of the rod-shaped part is short, it needs to be raised to a higher position so that the center of the shorter rod-shaped part can move within the vertical stroke range of the robot arm. Thus, when the shorter rod-shaped part is driven by the lifting plate 30 to rise to a position away from the positioning post 20, the second positioning rib 31 can position the rod-shaped part, ensuring that it is stably placed on the lifting plate 30 when it rises to a higher position. The addition of the second positioning rib 31 increases the lifting range of the docking platform for rod-shaped parts and improves the adaptability of the docking platform. The second positioning ribs 31 extend along the lifting direction of the lifting plate 30. Multiple second positioning ribs 31 are spaced apart on the outer circumferential side of the mounting hole 33, and can extend into the rod-shaped part. The multiple second positioning ribs 31 further ensure that the rod-shaped part is stably placed on the lifting plate 30 and that the force on the rod-shaped part is more evenly distributed. A second guide slope 32 is provided at the top of each second positioning rib 31, gradually moving away from the mounting hole 33 from top to bottom. The second guide slope 32 can guide and cooperate with the end of the rod-shaped part, allowing the end of the rod-shaped part to smoothly pass through the second guide slope 32 and be fitted onto the multiple second positioning ribs 31, improving the efficiency of fitting the rod-shaped part onto the multiple second positioning ribs 31.

[0042] like Figures 4 to 6 As shown in Embodiment 2, when the lifting plate 30 rises to its highest point, its upper surface is 2mm to 5mm higher than the top wall of the column body 21. Thus, when the lifting plate 30 reaches its highest point, the rod-shaped part is gripped by the robotic arm, and the lifting plate 30 is controlled to descend, allowing the rod-shaped part to disengage from the positioning column 20, creating a gap between the lower end face of the rod-shaped part and the upper surface of the positioning column 20. This eliminates the need for the robotic arm to move vertically; it can directly move the rod-shaped part above the work area for part installation or extension operations, improving work efficiency.

[0043] like Figures 4 to 6As shown, in Embodiment 2, the wall of the mounting hole 33 mates with the outer wall of the column body 21, so that the lifting plate 30 at the mounting hole 33 can better support the rod-shaped part, enabling the lifting plate 30 to stably drive the rod-shaped part to rise and fall. The wall of the mounting hole 33 is provided with a receiving groove 34 for accommodating the first positioning rib 23. The receiving groove 34 can accommodate the first positioning rib 23. Furthermore, the cooperation between the receiving groove 34 and the first positioning rib 23 can prevent rotation between the lifting plate 30 and the positioning column 20, allowing the lifting plate 30 to rise and fall along the direction of the first positioning rib 23, reducing the swaying of the lifting plate 30 during rising and falling, and improving the stability of the rod-shaped part during rising and falling. There are multiple receiving grooves 34, which are spaced apart circumferentially along the mounting hole 33 and correspond one-to-one with the multiple first positioning ribs 23. The cooperation between the multiple receiving grooves 34 and the multiple first positioning ribs 23 can further reduce the swaying of the lifting plate 30 during rising and falling. The second positioning rib 31 is disposed between two adjacent receiving grooves 34 to make the force on the rod-shaped part more uniform when it is sleeved on multiple first positioning ribs 23 or multiple second positioning ribs 31, thereby improving the stability of the rod-shaped part during lifting. The axis of the second positioning rib 31 is perpendicular to the upper surface of the lifting plate 30, which facilitates the processing of the second positioning rib 31.

[0044] In the second embodiment, the diameter of the mounting hole 33 matches the diameter of the column body 21, and the lifting plate 30 can be slidably mounted on the column body 21.

[0045] In an embodiment not shown, the axis of the second positioning rib gradually approaches the center of the mounting hole in the direction from bottom to top, so that the rod-shaped part can be more easily fitted onto the multiple second positioning ribs.

[0046] like Figure 2 and Figure 7 As shown in Embodiments 1 and 3, the positioning post 20 includes a post body 21 and a guide cone 22 protruding from the top of the post body 21. The outer side wall of the guide cone 22 gradually moves away from the axis of the guide cone 22 in the direction from top to bottom. The guide cone 22 can guide and cooperate with the end of the rod-shaped part, so that the end of the rod-shaped part can smoothly pass through the conical surface of the guide cone 22 and be sleeved on the outside of the positioning post 20, thereby improving the efficiency of the rod-shaped part being sleeved on the outside of the positioning post 20.

[0047] It should be noted that "guide cone 22 protruding from column body 21" means that: guide cone 22 always protrudes from column body 21, or guide cone 22 is retractably mounted on column body 21, and guide cone 22 has a guiding position protruding from column body 21. In Embodiment 1, guide cone 22 always protrudes from column body 21. In Embodiment 3, guide cone 22 is retractably mounted on column body 21, and guide cone 22 has a guiding position protruding from column body 21.

[0048] like Figure 7 As shown, in Embodiment 3, the arrangement of the guide cone 22 differs from that in Embodiment 1, and an extension column 43 is added based on Embodiment 1. The guide cone 22 is vertically and flexibly disposed within the positioning column 20, and the docking platform also includes a first driving member 41 disposed within the positioning column 20. The first driving member 41 drives the guide cone 22 to rise and fall, so that the guide cone 22 has a guiding position protruding from the top of the column body 21 and a retracted position within the positioning column 20. When the robot grips a long rod-shaped part and places it on the docking platform, the guide cone 22 protruding from the positioning column 20 may interfere with the bottom end of the long rod-shaped part. At this time, the guide cone 22 can be lowered to avoid the bottom end of the long rod-shaped part, further improving the adaptability of the docking platform.

[0049] In Embodiment 3, the side wall of the base 10 and the support plate 13 are provided with avoidance holes to avoid the connecting pipe or connecting line of the first driving component 41.

[0050] like Figure 7 As shown, in Embodiment 3, the docking platform also includes an extension column 43 disposed within the positioning column 20. The extension column 43 is connected to the bottom of the guide cone 22, and the first driving member 41 drives the extension column 43 to rise and fall, thereby driving the guide cone 22 to rise and fall. The extension column 43 has an extended position protruding from the top of the column body 21 and a retracted position retracted into the positioning column 20. The provision of the liftable extension column 43 allows the docking platform to adapt to more rod-shaped parts of different lengths, further expanding the adaptability of the docking platform. When the robot arm grips a longer rod-shaped part and places it on the docking platform, the extension column 43 protruding from the column body 21 may interfere with the bottom end of the longer rod-shaped part. In this case, the extension column 43 can be lowered to avoid the bottom end of the longer rod-shaped part. Connecting the extension column 43 to the bottom of the guide cone 22 allows the extension column 43 and the guide cone 22 to be driven simultaneously by the first driving member 41, simplifying the structure of the docking platform and facilitating processing and use.

[0051] In Embodiment 3, the conical surface of the guide cone 22 gradually moves away from the axis of the guide cone 22 from bottom to top.

[0052] Furthermore, in Embodiment 1, the base 10 includes a base plate 11, a support plate 13 disposed above the base plate 11, and a support column 12 connecting the base plate 11 and the support plate 13. The support plate 13 is located below the lifting plate 30, and the lifting plate 30 can descend to a position supported by the support plate 13, so that when the docking platform connects to the rod-shaped part, the lifting plate 30 can support the rod-shaped part, and the support plate 13 can support the lifting plate 30, making the support of the docking platform for the rod-shaped part more stable and improving safety. The docking platform also includes a second driving member 42 for driving the lifting plate 30 to rise and fall. One end of the second driving member 42 is connected to the base plate 11, and the other end of the second driving member 42 is connected to the lifting plate 30. The second driving member 42 passes through the support plate 13, and the support plate 13 is provided with a through hole to avoid the second driving member 42. In this way, the second driving member 42 can pass through the support plate 13 and drive the lifting plate 30 to rise and fall, and increase the driving stroke of the second driving member 42. Furthermore, the through hole can limit the swing of the second drive member 42, so that the second drive member 42 can drive the lifting plate 30 to rise and fall more smoothly.

[0053] In Embodiment 1, the base plate 11 and the support plate 13 are arranged in parallel, and the axis of the support column 12 is perpendicular to the top surface of the base plate 11 and the bottom surface of the support plate 13. The axis of the column body 21 is perpendicular to the top surface of the support plate 13, and the support column 12 is coaxially arranged with the column body 21 to improve stability when connecting rod-shaped parts. The height of the positioning column 20 matches the longest rod-shaped part, that is, when the longest rod-shaped part is placed on the connecting platform, the positioning column 20 can still prevent it from tipping over after being inserted into the longest rod-shaped part. The longest rod-shaped part refers to the longest rod-shaped part that the vertical shaft drilling rig can use without tipping over the drill frame. Because the height of the support column 12 matches the longest rod-shaped part, the insertion of the positioning column 20 can prevent the longest rod-shaped part from tipping over when it is placed on the connecting platform. When connecting shorter rod-shaped parts, the insertion of the positioning post 20 can prevent them from tipping over. In other words, regardless of the length of the rod-shaped part, when it is placed on the connecting platform for connection, the insertion of the support post 12 can prevent it from tipping over, making it widely applicable.

[0054] In Embodiment 1, the second driving component 42 is preferably a hydraulic cylinder or an electric cylinder, with the electric cylinder facilitating control of the lifting distance of the lifting plate 30. The second driving component 42 includes a cylinder body extending vertically and a push rod. The cylinder body is connected to the base plate 11, and the push rod passes through the support plate 13 and is connected to the lifting plate 30. There are two second driving components 42, arranged opposite each other about the axis of the support column 12. The outer wall of the support column 12 is provided with a first reinforcing inclined plate connected to the base plate 11 and a second reinforcing inclined plate connected to the support plate 13 to improve the reliability and stability of the base 10 during support.

[0055] In Embodiment 1, the upper surface of the base plate 11 is provided with a first hinge lug for connecting the cylinder body, and the lower surface of the lifting plate 30 is provided with a second hinge lug for connecting the push rod. The first hinge lug is rotatably connected to the cylinder body via a first pin, and the second hinge lug is rotatably connected to the push rod via a second pin. When the push rod retracts to its lowest point, the second hinge lug is inserted into the through hole on the lifting plate 30 to avoid the second driving member 42, so that the lower surface of the lifting plate 30 is in contact with the upper surface of the support plate 13, so that the support plate 13 can be supported on the lifting plate 30. When the lifting plate 30 rises to its highest point, the distance between the upper surface of the lifting plate 30 and the upper surface of the positioning post 20 is less than or equal to two-thirds of the height of the positioning post 20.

[0056] like Figure 8 As shown, in Embodiment 4, an elastic buffer 50 is added based on Embodiment 1. The connecting platform also includes an elastic buffer 50, which is disposed between the support plate 13 and the lifting plate 30. There are multiple elastic buffers 50, which are spaced apart circumferentially along the positioning post 20. After the rod-shaped part is placed on the lifting plate 30, the lifting plate 30 descends. The elastic buffer 50 can buffer the lifting plate 30 and make the lifting of the lifting plate 30 more stable, reducing scratches on the inner wall of the rod-shaped part caused by the rod-shaped part tilting when the lifting plate 30 is suddenly subjected to force or uneven force. The elastic buffer 50 can also reduce the instantaneous load when the lifting plate 30 starts, making the lifting of the lifting plate 30 more stable and smooth. Furthermore, due to the elastic properties of the elastic buffer 50, when the rod-like parts supported by the lifting plate 30 are relatively heavy, the elastic buffer 50 is compressed by a large amount, so that the lifting plate 30 can automatically adjust the descent distance and descent position of the lifting plate 30 according to the weight of the rod-like parts under the action of the elastic buffer 50.

[0057] In embodiment four, the elastic buffer 50 is a spring, and there are four springs, which are evenly distributed around the circumference of the positioning post 20. Due to the setting of the elastic buffer 50, when the lifting plate 30 descends to the limit position, the lifting plate 30 does not fit with the support plate 13, and the support plate 13 supports the lifting plate 30 through the elastic buffer 50.

[0058] like Figure 9 As shown, in Embodiment 5, an elastic buffer 50 is added based on Embodiment 2.

[0059] like Figure 10As shown, in Embodiment Six, the structure of the first positioning rib 23 differs from that in Embodiment One. The first positioning rib 23 includes an upper rib 231 and a lower rib 232. The lower rib 232 is located at the bottom end of the first positioning rib 23, and the upper rib 231 is connected above the lower rib 232. A first guide slope 24 is provided at the top of the upper rib 231. The upper rib 231 is a rigid member, and the maximum distance between the outer surface of the upper rib 231 and the column body 21 remains constant. The lower rib 232 is an elastic member, and the maximum distance between the outer surface of the lower rib 232 and the column body 21 gradually increases from top to bottom. The elastic member can be interference-fitted with the rod-shaped part. The upper rib 231 is a rigid member, so that when the bottom end of the rod-shaped part is sleeved on the upper rib 231, it can slide smoothly downwards, so that the lifting plate 30 can be supported on the bottom wall of the rod-shaped part. The lower rib 232 is an elastic element, and the lower rib 232 is interference-fitted with the rod-shaped part, so that the bottom end of the rod-shaped part and the lower rib 232 fit more tightly, thereby reducing the shaking of the rod-shaped part on the positioning post 20, and making the lifting and lowering of the rod-shaped part more stable and safe.

[0060] In Embodiment Six, the upper rib 231 is preferably made of metal, such as steel or iron. The lower rib 232 is preferably made of rubber or polymer material.

[0061] The inventors discovered that in related technologies, the assembly and disassembly of drill pipes for vertical shaft drilling rigs is done by construction workers. This requires first tilting the power head and drill frame, then using a crane to lift and transport the drill pipe sections for installation. This process is extremely time-consuming and inefficient, and the drill pipe sections are prone to swaying during the process, posing a significant safety hazard to construction workers and other equipment. Later, a robotic arm was used to clamp and move the drill pipe sections to the location where they would be installed, completing the drill pipe extension and installation operation. However, when the robotic arm is gripping rod-shaped parts of different lengths, the high requirements for its vertical travel and the limited space under the vertical shaft drilling frame necessitate changing the height of the docking platform to raise or lower the height of the docking platform when connecting the drill pipe sections, in order to adjust the midpoint of the drill pipe sections of different lengths. However, such docking platforms make the operation complex and have a limited scope of application.

[0062] To address the aforementioned issues, the technical solution of this application involves placing the docking platform on the bottom support of the vertical shaft drilling rig, positioned to one side of the drill pipe to be installed. Since the lifting plate 30 can move the drill pipe segments up and down to adjust their midpoint positions, the requirements for the manipulator's vertical travel are reduced. Furthermore, the operation is simple, expanding the docking platform's applicability. When removing longer drill pipe segments, although the optimal force application point of the segment itself is higher, the lifting plate 30 needs to be lowered during hoisting and docking, with the support plate 13 resting on it. This lowers the optimal force application point of the longer segment, accommodating the shorter travel of the manipulator. Conversely, when removing shorter drill pipe segments, although the optimal force application point is lower, the lifting plate 30 can be raised to move the shorter segment upwards, raising its optimal force application point and accommodating the shorter travel of the manipulator. This reduces the requirements for the vertical travel of the robotic arm, making it widely applicable.

[0063] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0064] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0065] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0066] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
