Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of drilling platform technology, and more specifically, to a variable finger beam system. Background Technology

[0002] The finger beams of the drilling rig's second tier are devices used to store and deploy drill pipes and other tubing during drilling operations. They are typically installed on both sides of the second tier of the derrick. A finger beam generally consists of several parallel metal rods or beams, symmetrically installed vertically on opposite sides of the second tier. The length and spacing of each finger beam vary depending on the drilling equipment and drill pipe specifications. One end is usually connected to the structural frame of the second tier, while the other end is suspended, forming a finger-like arrangement, hence the name "finger beam."

[0003] Its main function is to neatly and orderly arrange and store drill pipe stands. During the drilling process, as the drilling depth increases, drill pipe needs to be continuously pulled up and down. The finger beam provides a temporary storage location for the drill pipe, facilitating the driller's operation and management. In addition, the finger beam also provides a certain degree of restraint and fixation for the drill pipe, reducing its swaying and swinging on the secondary platform and improving operational safety.

[0004] Traditional two-tier platform finger beams are mostly fixed-spacing structures. There are also some two-tier platform drill rod finger beams that can automatically adjust the spacing of the pipe rows, but they have the problems of occupying a large internal volume of the two-tier platform, being heavy, and having complex adjustment technology. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a variable finger beam system, which solves the technical problems of existing finger beams with adjustable spacing between two-layer drill rods, which occupy a large internal volume of the two-layer platform, are heavy, and have complex adjustment requirements.

[0007] The platform has a vertically connected working space.

[0008] Finger beams, there are several finger beams, all of which are slidably arranged on the platform and located within the working space. There is a drill rod space between two adjacent finger beams, and the drill rod space is used to accommodate a row of drill rods.

[0009] A synchronization component is disposed on the platform and is used to drive the plurality of finger beams to move closer to or further away from each other.

[0016] For example, in at least one embodiment of this disclosure, a variable finger beam system is provided in which the distance between the two hinge axes of the folding link at the end furthest from the fixed link is equal to the distance between the two hinge axes of the fixed link, and the distance between the two hinge axes of the remaining folding links is twice the distance between the two hinge axes of the fixed link.

[0017] For example, at least one embodiment of this disclosure provides a variable finger beam system, wherein the folding link has a guide portion, the platform also has a second guide groove, the guide portion is rotatably and slidably disposed in the second guide groove; the sliding direction of the power head is parallel to the sliding direction of the finger beam and parallel to the sliding direction of the guide portion.

[0018] For example, at least one embodiment of this disclosure provides a variable finger beam system, wherein the guide portion is cylindrical, and the hinge axis of the folding link and the finger beam is coaxially arranged with the guide portion.

[0019] For example, at least one embodiment of this disclosure provides a variable finger beam system, wherein the synchronization component is a scissor-type telescopic frame, the scissor-type telescopic frame having a plurality of central hinge axes and a plurality of side hinge axes, the plurality of central hinge axes being arranged collinearly, and each of the central hinge axes being hinged to one of the finger beams.

[0020] For example, at least one embodiment of this disclosure provides a variable finger beam system in which the central hinge shaft at one end is rotatably mounted on the platform, and the central hinge shaft at the other end slides and rotates relative to the platform and is moved by a power head.

It also boasts advantages such as small footprint, simple structure, and light weight. Attached Figure Description

[0029] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0034] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0035] like Figures 1-3As shown, a variable finger beam system is illustrated in one embodiment of this disclosure. This system, through the cooperation of a platform 100, finger beams 200, and a synchronization component 300, achieves flexible and efficient adjustment of the finger beam spacing. By connecting multiple finger beams 200 using the synchronization component 300, stepless adjustment of the finger beam spacing is achieved, thus adapting to different drill pipe specifications and operating scenarios. It also boasts advantages such as small footprint, simple structure, and light weight.

[0036] The platform 100 is generally rectangular in shape, with a vertically connected working space 101. The working space 101 is used for drill pipes to pass through, ensuring that the drill pipes can be stored smoothly and that there is operating space above. The length and width of the platform 100 are determined based on the actual space of the two-tier platform and the number and layout of the finger beams 200.

[0037] Slide grooves are provided along the length of both sides inside the platform 100. A slider adapted to the slide groove is installed at one end of the finger beam 200, while the other end is suspended. The slider is firmly connected to the finger beam 200, allowing the finger beam 200 to slide smoothly within the slide groove. The length of the slide groove meets the sliding requirements of the finger beam 200 between its maximum and minimum spacing.

[0038] The finger beam 200 is made in the shape of a rod or beam. Its length is set according to the drill pipe length and load-bearing requirements to ensure stable support for the drill pipe. The cross-section of the finger beam 200 can be circular, rectangular, etc., to meet different strength and space utilization requirements. In addition to a slider connected to the platform 100, one end of the finger beam 200 is also provided with a connection structure connected to the synchronization component 300, so as to facilitate the spacing adjustment of multiple finger beams 200 driven by the synchronization component 300.

[0039] Multiple finger beams 200 are arranged in parallel within the working space 101, forming a drill pipe space 201 between adjacent finger beams 200 to accommodate a row of drill pipes. Under the action of the synchronization component 300, the finger beams 200 move synchronously along the sliding groove of the platform 100, moving closer or further away, thereby adjusting the size of the drill pipe space 201 to accommodate drill pipes of different specifications. For example, for small-diameter drill pipes, the synchronization component 300 drives the finger beams 200 to move closer, reducing the drill pipe space 201; for large-diameter drill pipes, it drives the finger beams 200 to move further away, increasing the drill pipe space 201.

[0040] The synchronization component 300 offers multiple drive options, commonly including electric, hydraulic, and pneumatic drives. Electric drives utilize a motor paired with a reducer; the motor provides power, and the reducer regulates speed and torque. The motor and reducer are connected via a coupling to ensure efficient power transmission. Hydraulic drives require a hydraulic pump, hydraulic cylinders, and related hydraulic lines and control valves. The hydraulic pump pressurizes hydraulic oil and delivers it to the hydraulic cylinder, pushing the piston and moving the finger beam 200. Pneumatic drives rely on an air compressor, cylinders, air lines, and control valves, using compressed air to push the cylinder piston, thus moving the finger beam 200.

[0041] Compared to traditional adjustable finger beams, this variable finger beam system has a compact structure. The finger beam 200 is placed within the working space 101 of the platform 100 and driven by the synchronization component 300, significantly reducing its volume occupied in the second-level platform. At the same time, the optimized structure reduces the overall weight of the system, making it easier to install, disassemble, and maintain, and more adaptable to the limited space of the second-level platform.

[0042] The finger beam spacing is infinitely adjustable using the synchronization component 300. Operators can easily change the finger beam spacing by controlling the drive device of the synchronization component 300, making operation simple and convenient. This infinitely adjustable spacing can precisely adapt to different drill pipe specifications, significantly improving the flexibility and efficiency of drill pipe storage and operation. In actual operation, the time required to adjust the finger beam spacing is shortened when changing drill pipe specifications.

[0043] It can quickly and accurately adjust the finger beam spacing according to different drilling operation scenarios and drill pipe specifications. Whether it is conventional drilling or special drilling projects, it can provide suitable storage space for drill pipe. This adaptability enhances the versatility of drilling operations, reduces problems such as unstable drill pipe storage or low operation efficiency caused by improper finger beam spacing, and improves the safety and reliability of the entire drilling operation.

[0044] In some examples, such as Figure 1 As shown, the inlet 1011 on one side of the workspace 101, the space 102 between the finger beam 200 and the platform 100, and their connectivity can be adjusted to improve the path and space utilization efficiency of the drill pipe entering the variable finger beam system. The inlet 1011 is arranged parallel to the finger beam 200, allowing the drill pipe to enter the system more smoothly along the finger beam 200. The space 102 connects to the inlet 1011 and the drill pipe space 201, providing a transition space for the drill pipe before entering the drill pipe space 201. This helps guide the drill pipe accurately into the drill pipe space 201 and also facilitates necessary adjustments and operations by the operator during the drill pipe's entry, improving the overall system's efficiency in accepting and managing the drill pipe.

[0045] The inlet 1011 is located on one side wall of the working space 101, and its orientation can be parallel to the arrangement direction of the finger beams 200. The length of the inlet 1011 is determined according to the length of the finger beams 200 and the operating space requirements of the drill pipe, so as to ensure that the drill pipe can easily enter the interval space 102 from the inlet 1011.

[0046] The edges of the inlet 1011 can be chamfered to prevent the drill pipe from being scratched by sharp edges during entry. Simultaneously, guide structures, such as guide plates or guide wheels, can be installed on both sides of the inlet 1011 to guide the drill pipe accurately into the space 102. The guide wheels are mounted on shafts on both sides of the inlet 1011. When the drill pipe contacts the guide wheels, the guide wheels roll, further reducing the friction during drill pipe entry and making the entry smoother.

[0047] The space 102 refers to the space formed around the finger beam 200 between the beam 200 and the platform 100. It extends along the length of the finger beam 200, starting from the inlet 1011 and connecting to the drill pipe space 201.

[0048] The inlet 1011 is directly connected to the partition space 102, and the partition space 102 is also connected to the drill pipe space 201. This connection ensures that after the drill pipe enters from the inlet 1011, it can pass through the partition space 102 sequentially and finally reach the drill pipe space 201 for storage. At the connection points, a smooth transition is ensured, with no protrusions or depressions that would obstruct the passage of the drill pipe.

[0049] When the drill pipe is ready to enter the variable finger beam system, the operator aligns the drill pipe with the inlet 1011. Guided by the guide structure, the drill pipe enters the spacer space 102 along the inlet 1011. After moving to the appropriate position in the spacer space 102, the drill pipe is then fed into the drill pipe space 201. When it is necessary to remove the drill pipe, the operation is reversed: the drill pipe passes from the drill pipe space 201 through the spacer space 102 and then exits the variable finger beam system through the inlet 1011.

[0050] The design of the imported 1011 parallel to the direction of the finger beam 200, and its connection structure with the interval space 102 and the drill pipe space 201, makes the entry and exit of the drill pipe into and out of the variable finger beam system smoother. Compared with the traditional drill pipe entry method, the drill pipe entry and exit time is shortened, reducing the operational difficulty and time cost for operators, and improving the efficiency of drill pipe management.

[0051] The space 102 provides transition and adjustment space for the drill pipe, achieving more rational space utilization within the limited space of the platform 100. Operators have more operating space to adjust the drill pipe position during insertion, reducing the probability of incorrect drill pipe placement, improving the accuracy of drill pipe placement, and further enhancing the reliability and practicality of the entire system.

[0052] The aforementioned variable finger beam system can better adapt to drill pipes of different lengths and diameters. Whether the drill pipe is short or long, it can smoothly enter the drill pipe space 201 through the inlet 1011 and the space 102. The system's adaptability to different specifications of drill pipes is improved, broadening the application range of the variable finger beam system in different drilling operation scenarios.

[0053] In some examples, such as Figure 1As shown, setting two symmetrically distributed workspaces 101 with their inlets 1011 adjacent to each other further optimizes the spatial layout and drill pipe management efficiency of the variable finger beam system. The double-symmetrical workspaces 101 fully utilize the space of the platform 100, increasing the drill pipe storage capacity. The adjacent inlets 1011 facilitate operator work on the drill pipe within the same area; whether feeding or retrieving the drill pipe, there is no need for extensive movement, improving operational convenience. Simultaneously, the symmetrical structure helps the system maintain balance when carrying the drill pipe, enhancing system stability.

[0054] Inside the platform 100, two workspaces 101 are symmetrically distributed. For example, if the platform 100 is considered as a cuboid, the two workspaces 101 are located on opposite sides of the cuboid and are symmetrical about the central axis of the platform 100. The frame structure of the platform 100 can be assembled by welding or bolting to ensure structural stability.

[0055] Each workspace 101 is vertically connected to accommodate drill pipe. Within each workspace 101, several finger beams 200 are arranged in parallel, and drill pipe spaces 201 are formed between adjacent finger beams 200.

[0056] Each workspace 101 has a synchronization component 300 installed on one side, which drives the finger beams 200 in each workspace 101 to adjust their spacing, thereby achieving stepless adjustment of the spacing between the drill pipe spaces 201. This configuration ensures the independence of the finger beam 200 adjustment in the two workspaces 101, allowing the equipment to adapt to the need for simultaneous discharge of different drill pipes.

[0057] The design of the dual-symmetric workspace 101 makes fuller use of the space on the platform 100, nearly doubling the drill pipe storage capacity compared to a single-workspace variable finger beam system. With the same floor area, more drill pipe can be stored, improving the efficiency of the second-level platform space and meeting the higher demands of drilling operations for drill pipe storage.

[0058] With the inlets 1011 positioned adjacent to each other, operators do not need to move back and forth between different positions on the platform 100 when operating the drill pipe. The operating range is concentrated, and the operation time is shortened compared to designs with non-adjacent inlets. This not only reduces the labor intensity of operators but also improves the efficiency of drill pipe operation and reduces errors that may be caused by inconvenience in operation.

[0059] The symmetrical structure of the dual working spaces 101 ensures more even stress distribution when the system supports the drill pipe, improving stability compared to asymmetrical structures. In the vibration environment of drilling operations, it better maintains balance, reducing the risk of drill pipe slippage or equipment damage due to system instability and ensuring safe drilling operations.

[0060] In some examples, such as Figure 2 As shown, the platform 100 is provided with a first guide groove 103. The finger beam 200 slides within the first guide groove 103 via a square sliding part to improve the stability of the finger beam 200's sliding. The first guide groove 103 provides a clear trajectory for the movement of the finger beam 200, limiting its displacement in unexpected directions and ensuring that the finger beams 200 can smoothly and accurately move closer or further apart under the drive of the synchronization component 300. This enables the adjustment of the drill pipe space 201 spacing to meet the storage requirements of drill pipes of different specifications.

[0061] The first guide groove 103 is disposed inside the platform 100, extending along the length of the platform 100 and consistent with the arrangement direction of the finger beams 200. Each working space 101 has two side walls provided with the first guide groove 103 to ensure the stability of the finger beams 200 during sliding. The number and layout of the guide grooves are determined according to the number and length of the finger beams 200, ensuring that each finger beam 200 can move smoothly under the guidance of the guide grooves.

[0062] The cross-sectional shape of the first guide groove 103 can be square, which is adapted to the square sliding part of the finger beam 200. The square sliding parts provided at both ends of the finger beam 200 need to ensure that the finger beam 200 can slide freely in the first guide groove 103, while effectively limiting its sway.

[0063] When the finger beam 200 is installed on the platform 100, the square sliding part is embedded in the first guide groove 103. During the movement of the finger beam 200 driven by the synchronization component 300, the square sliding part slides along the inner wall of the first guide groove 103. Due to the tight fit between the square sliding part and the guide groove, the finger beam 200 can move smoothly along the predetermined trajectory without deviation or jamming, thus ensuring the accuracy of the drill pipe space 201 spacing adjustment.

[0064] In some examples, such as Figures 2-3 As shown, this variable finger beam system employs a synchronous assembly 300 consisting of folding connecting rods 301, a power head 302, and fixed connecting rods 303, thereby achieving stepless adjustment of the finger beam spacing 200 in a compact, lightweight, and flexible manner. The folding connecting rods 301 are sequentially hinged to form a telescopic structure. The sliding of the power head 302 causes each folding connecting rod 301 to unfold or fold, thereby bringing the finger beams 200 hinged to the folding connecting rods 301 closer together or further apart. This structure not only occupies less internal volume on the second-level platform, reducing its burden, but also possesses high flexibility, enabling simultaneous and precise adjustment of the spacing between several finger beams 200 to meet different drill pipe storage needs, and is time-saving and convenient to operate.

[0065] The folding link 301 is a rod-shaped structure with hinges at both ends for hinged connection with adjacent folding links 301 and the transmission link 202 of the finger beam 200. The hinges are connected by a pin, which passes through the folding link 301 and the connected components, and is fixed by a nut or cotter pin to ensure that the hinge can rotate flexibly while having sufficient connection strength.

[0066] Several folding links 301 are sequentially hinged end to end to form a telescopic link chain. In the actual layout, the link chain is arranged along the length of the platform 100, located within the workspace 101, and does not affect the sliding of the finger beam 200 within the first guide groove 103. Each folding link 301 is hinged to a transmission link portion 202 of a finger beam 200, with the hinge point located at the middle of the folding link 301. This layout allows the folding link 301 to uniformly drive the finger beam 200 to move during extension and retraction.

[0067] The power head 302 is a block-shaped structure. One end can be hinged to any folding link 301, thereby driving the folding link 301 to achieve folding. Preferably, it is hinged to one folding link 301. The other end is provided with a slider that mates with a dovetail groove on the platform 100. The dovetail groove is formed on the side wall of the platform 100 and extends along the length of the platform 100. The slider of the power head 302 is embedded in the dovetail groove, forming a sliding pair, ensuring that the power head 302 can only slide along the direction of the dovetail groove, thus guiding the movement of the power head 302.

[0068] The power head 302 can be driven by an electric, hydraulic, or pneumatic device. For example, when using an electric drive, a motor and a lead screw are mounted on the platform 100, and the lead screw engages with a nut on the power head 302. When the motor starts, the lead screw rotates, causing the power head 302 to slide along the dovetail groove. If a hydraulic or pneumatic drive is used, a hydraulic cylinder or air cylinder is installed on the platform 100, and the power head 302 is pushed to slide by hydraulic oil or compressed air.

[0069] The fixed link 303 is also a rod-shaped structure, with one end hinged to the folding link 301 at the other end, and the other end hinged to the platform 100. The function of the fixed link 303 is to provide a fixed end point for the linkage chain formed by the folding link 301, so that the folding link 301 can be stably unfolded or folded under the drive of the power head 302. The hinge point between the fixed link 303 and the platform 100 is located at a suitable position at the end or side of the platform 100, ensuring that the fixed link 303 will not interfere with other components during the movement of the folding link 301.

[0070] The transmission link 202 of the finger beam 200 extends from the side of the main body of the finger beam 200 and is a relatively short rod-shaped structure. Its end is provided with a hinge hole, which is hinged to the hinge part in the middle of the folding link 301 via a pin. The length and position design of the transmission link 202 must ensure that the finger beam 200 can slide smoothly within the first guide groove 103 under the drive of the folding link 301, and that the distance between the finger beams 200 changes uniformly.

[0071] When it is necessary to increase the distance between the finger beams 200, the power drive device is activated, causing the power head 302 to slide along the dovetail groove away from the fixed connecting rod 303. The movement of the power head 302 causes the folding connecting rod 301 hinged to it to unfold. As each folding connecting rod 301 is hinged in sequence, the entire linkage chain gradually lengthens. During this process, the finger beams 200 hinged to the folding connecting rods 301 receive an outward pulling force through the transmission connecting rod part 202. Under the guidance of the first guide groove 103, the finger beams 200 slide to both sides along the guide groove, thereby increasing the drill pipe space 201 spacing between adjacent finger beams 200.

[0072] When it is necessary to reduce the distance between the finger beams 200, the power drive device reverses its direction, causing the power head 302 to slide along the dovetail groove towards the fixed connecting rod 303. The movement of the power head 302 causes the folding connecting rod 301 to gradually fold, shortening the connecting rod chain. At this time, the finger beams 200, which are hinged to the folding connecting rod 301, receive an inward thrust through the transmission connecting rod part 202. Under the guidance of the first guide groove 103, the finger beams 200 slide towards the center along the guide groove, thereby reducing the drill pipe space 201 spacing between adjacent finger beams 200.

[0073] The synchronous assembly 300 structure, which employs a folding connecting rod 301, a power head 302, and a fixed connecting rod 303, occupies less internal volume and is lighter compared to the traditional finger beam spacing adjustment structure. This significantly reduces the burden on the second-level platform, allowing it to better support the drill pipe within a limited space. It also lowers the structural strength requirements for the second-level platform, reducing construction and maintenance costs.

[0074] The synchronization component 300 enables stepless adjustment of the spacing between the finger beams 200, and can simultaneously and precisely adjust the spacing of several finger beams 200. This improves adjustment flexibility and accuracy. Consequently, the variable finger beam system can more quickly and accurately adapt to the storage needs of drill pipes of different specifications, enhancing the stability and safety of drill pipe storage.

[0075] The spacing of multiple finger beams 200 can be adjusted synchronously by a single drive of the power head 302, making the operation time-saving and simple. Compared with the traditional complex adjustment operation, the time required to adjust the spacing of the finger beams 200 is shortened, improving the efficiency of drill pipe management, reducing the workload of operators, and improving the overall efficiency of drilling operations.

[0076] In some examples, such as Figures 2-3 As shown, the distance between the two hinge axes of the folding link 301 at the end furthest from the fixed link 303 is designed to be equal to the distance between the two hinge axes of the fixed link 303. The distance between the two hinge axes of the remaining folding links 301 is set to twice the distance between the two hinge axes of the fixed link 303, which optimizes the motion characteristics of the synchronization component 300. Through this specific proportional relationship, the folding link 301 and the fixed link 303 work together to provide a more uniform and stable driving force for the finger beam 200, ensuring that the finger beam 200 moves synchronously and stably, accurately controlling the spacing of the drill pipe space 201, and adapting to different drill pipe storage requirements.

[0077] The distance between the two hinge axes of the folding link 301 is set to twice the corresponding distance of the fixed link 303. This allows the folding link 301 to better adjust the position of the finger beam 200 when the synchronization component 300 is operating. The transmission link part that is hinged to the finger beam 200 in the middle ensures that the finger beam 200 can move smoothly with the movement of the folding link 301.

[0078] The fixed connecting rod 303 has a distance between its two hinge axes that is half the corresponding distance of the folding connecting rod 301. One end is hinged to the chain end of the folding connecting rod 301, and the other end is securely hinged to the platform 100. As the fixed end of the synchronization component 300, it limits the range of motion of the folding connecting rod 301, guides it to swing regularly around the fixed hinge point, and ensures that the finger beam 200 moves according to a predetermined trajectory and spacing.

[0079] In some examples, such as Figure 2 As shown, in the variable finger beam system based on the folding connecting rod 301, a guide part 3011 is provided for the folding connecting rod 301, and a second guide groove 104 is opened on the platform 100 to cooperate with it. Simultaneously, the sliding directions of the power head 302, the finger beam 200, and the guide part 3011 are kept parallel, which can further improve the stability and accuracy of the system's movement. The rotating and sliding arrangement of the guide part 3011 within the second guide groove 104 provides more precise guidance for the movement of the folding connecting rod 301, reducing its offset and swaying during movement. The consistency of the sliding directions of each component ensures that the force transmission is more direct and efficient when adjusting the finger beam 200 spacing, avoiding additional stress and energy loss caused by inconsistent directions. This achieves smooth and precise adjustment of the finger beam 200 spacing, better meeting the storage needs of drill pipes of different specifications.

[0080] The guide part 3011 is provided on the folding connecting rod 301, and its shape can be designed as a cylinder to accommodate rotation and sliding within the second guide groove 104.

[0081] The second guide groove 104 is formed on the platform 100, and its shape is adapted to the guide part 3011, for example, it is a rectangular or strip groove. The length of the second guide groove 104 extends along the length direction of the platform 100 to meet the guiding requirements of the folding connecting rod 301 throughout the movement. Limiting structures, such as limiting blocks or limiting protrusions, can be provided at both ends of the second guide groove 104 to prevent the guide part 3011 from falling out of the groove.

[0082] The power head 302 is slidably mounted on the platform 100 via a dovetail groove or similar structure. Its sliding direction is strictly parallel to the sliding direction of the finger beam 200 in the first guide groove 103 and the sliding direction of the guide part 3011 in the second guide groove 104. The drive device of the power head 302, such as a motor, hydraulic cylinder, or pneumatic cylinder, must be installed in a direction consistent with the aforementioned sliding direction to ensure that the power head 302 can smoothly drive the folding linkage 301.

[0083] The finger beam 200 slides within the first guide groove 103 via a square sliding part. The first guide groove 103 is parallel to the second guide groove 104, thus ensuring that the sliding direction of the finger beam 200 is consistent with the sliding direction of the guide part 3011. This parallel arrangement allows the force to be effectively transmitted when the folding connecting rod 301 moves the finger beam 200, avoiding uneven movement or jamming of the finger beam 200 due to directional deviation.

[0084] When it is necessary to increase the spacing between the finger beams 200, the power head 302 moves along a sliding direction parallel to the finger beams 200 and the guide portion 3011 under the action of the drive device. The movement of the power head 302 drives the folding link 301 hinged to it to move. The guide portion 3011 on the folding link 301 rotates and slides within the second guide groove 104, providing guidance for the movement of the folding link 301. As the folding link 301 unfolds, the finger beams 200 hinged to the folding link 301 move to both sides within the first guide groove 103 along a sliding direction parallel to the guide portion 3011, thereby increasing the spacing of the drill pipe space 201 between adjacent finger beams 200. During this process, due to the consistency of the sliding direction of each component, the force transmission is smooth, and the finger beams 200 can move smoothly and synchronously.

[0085] When it is necessary to reduce the spacing between the finger beams 200, the power head 302 moves in the opposite direction. The guide part 3011 on the folding link 301 rotates and slides in the second guide groove 104 in the opposite direction, the folding link 301 folds, and drives the finger beams 200 to move towards the center in the first guide groove 103, reducing the spacing between the drill pipe spaces 201. Similarly, the parallel arrangement of the sliding directions of each component ensures the smoothness and synchronicity of the movement of the finger beams 200, realizing the adjustment of the spacing between the finger beams 200.

[0086] The cooperation between the guide section 3011 and the second guide groove 104, as well as the consistency of the sliding direction of each component, significantly reduces the swaying and offset of the folding connecting rod 301 and the finger beam 200 during movement. Precise guidance and consistent sliding direction ensure the positional accuracy of the finger beam 200 during spacing adjustment. Compared to traditional structures, the error in the spacing adjustment of the finger beam 200 is reduced, enabling it to more accurately adapt to the storage needs of drill pipes of different specifications, improving the stability and safety of drill pipe storage, and reducing drill pipe swaying or slippage problems caused by inaccurate spacing.

[0087] In some examples, such as Figures 2-3 As shown, the guide part 3011 is cylindrical, and the folding connecting rod 301 is coaxial with the hinge axis of the finger beam 200 and the guide part 3011, thereby optimizing the stability and motion performance of the variable finger beam system. The cylindrical guide part 3011 can uniformly guide the folding connecting rod 301, reducing friction and jamming; the coaxial setting makes force transmission more direct and efficient, avoiding asynchronous structural deformation and finger beam movement, thereby improving the accuracy and stability of the finger beam 200 spacing adjustment.

[0088] The power head 302 drives the folding link 301 to unfold. The folding link 301 slides along the cylindrical guide part 3011 and is subjected to uniform guiding force. Because the hinge shaft and the guide part are coaxial, the force is transmitted directly, and the finger beam 200 moves smoothly to both sides, uniformly increasing the spacing of the drill pipe space 201.

[0089] The power head 302 drives the folding link 301 to fold, and the folding link 301 slides in the opposite direction along the guide part 3011. The cylindrical guide and coaxial hinge ensure that the finger beams 200 move smoothly towards the center, accurately reducing the spacing of the drill pipe space 201, and keeping each finger beam 200 synchronized.

[0090] The cylindrical guide section and coaxial hinge allow for more even force distribution on the folding connecting rod 301, reducing the risk of structural deformation. The cylindrical guide and coaxial hinge also reduce friction and jamming, decreasing the resistance to movement of the finger beam 200, resulting in smoother adjustment and improved efficiency. The coaxial design ensures accurate drive, with the finger beam 200 moving synchronously and precisely, reducing spacing adjustment errors and better adapting to drill pipe storage needs, thus improving storage stability and safety.

[0091] In some examples, such as Figure 4As shown, a scissor-type telescopic frame 304 can also be used as a synchronization component 300, and is hinged to the finger beams 200 via a central hinge shaft 3041, thus providing another compact, efficient, and stable method for adjusting the finger beam spacing in the variable finger beam system. The structural features of the scissor-type telescopic frame 304 enable it to synchronously drive multiple finger beams 200 to move during telescopic movement via the central hinge shaft 3041, achieving stepless adjustment of the finger beam spacing. The collinear arrangement of several central hinge shafts 3041 ensures uniform force transmission, allowing each finger beam 200 to synchronously and smoothly approach or move away, thereby precisely controlling the spacing of the drill pipe space 201 to accommodate the storage requirements of drill pipes of different specifications. Simultaneously, the compact structure of the scissor-type telescopic frame 304 helps reduce the space occupied inside the second-level platform.

[0092] The scissor-type telescopic frame 304 consists of multiple intersecting connecting rods, forming a structure similar to the opening and closing of scissors. The scissor-type telescopic frame 304 has several central hinge shafts 3041 and several side hinge shafts 3042. The central hinge shafts 3041 are arranged collinearly, serving as the connection points for the finger beams 200 and transmitting power. Each central hinge shaft 3041 is hinged to one finger beam 200, ensuring that the finger beams 200 can move synchronously with the extension and retraction of the scissor-type telescopic frame 304. The side hinge shafts 3042 are used to connect adjacent connecting rods, enabling the scissor-type telescopic frame 304 to maintain structural stability and integrity during extension and retraction.

[0093] The finger beam 200 is provided with a hinge hole that matches the central hinge shaft 3041. The central hinge shaft 3041 passes through the hinge hole of the finger beam 200 and the corresponding connecting rod hinge part, firmly connecting the finger beam 200 to the scissor-type telescopic frame 304. To ensure the reliability of the connection, nuts or elastic retaining rings are used to fix both ends of the central hinge shaft 3041 to prevent the hinge shaft from falling off during operation. At the same time, an appropriate amount of lubricating grease is applied to the hinge part to reduce friction and make the movement of the finger beam 200 driven by the scissor-type telescopic frame 304 smoother.

[0094] Because several central hinge shafts 3041 are collinearly arranged, the finger beams 200 are evenly distributed on one side of the scissor-type telescopic frame 304 via these central hinge shafts 3041. This arrangement allows the scissor-type telescopic frame 304 to act with the same driving force on each finger beam 200 during telescopic movement, ensuring the synchronicity and consistency of the movement of the finger beams 200.

[0095] The scissor-type telescopic frame 304 can be driven by various power sources, commonly electric, hydraulic, or pneumatic. If electric drive is used, a motor and lead screw mechanism can be installed on the platform 100, with the lead screw connected to one end of the scissor-type telescopic frame 304. When the motor starts, the lead screw rotates, pushing the scissor-type telescopic frame 304 to extend or retract. If hydraulic drive is selected, a hydraulic pump, hydraulic cylinder, and corresponding hydraulic lines and control valves are required. The hydraulic pump pressurizes hydraulic oil and delivers it to the hydraulic cylinder, which in turn drives the scissor-type telescopic frame 304 to extend or retract via the piston movement of the hydraulic cylinder. Pneumatic drive relies on compressed air provided by an air compressor, which drives the scissor-type telescopic frame 304 through a cylinder.

[0096] Taking electric drive as an example, when it is necessary to increase the spacing of the finger beams 200, the motor rotates forward, and the lead screw pushes the scissor-type telescopic frame 304 to unfold. As the scissor-type telescopic frame 304 unfolds, the distance between the central hinge shafts 3041 increases, thereby driving the finger beams 200 hinged to it to move to both sides along the first guide groove 103, increasing the spacing of the drill pipe space 201. When it is necessary to decrease the spacing of the finger beams 200, the motor reverses, the lead screw pulls the scissor-type telescopic frame 304 to retract, the distance between the central hinge shafts 3041 decreases, and the finger beams 200 move towards the center under the drive of the scissor-type telescopic frame 304, decreasing the spacing of the drill pipe space 201. Throughout the entire driving process, the scissor-type telescopic frame 304 controls the movement of the finger beams 200 through the central hinge shafts 3041, realizing stepless adjustment of the spacing of the finger beams 200.

[0097] The 304 scissor-type telescopic frame has a compact structure, reducing the space it occupies inside the second-level platform compared to some complex synchronous components. Simultaneously, it can efficiently achieve stepless adjustment of the finger beam spacing (200mm), with an improved adjustment speed compared to traditional structures, quickly meeting the storage spacing requirements of different drill pipe specifications and enhancing drill pipe management efficiency.

[0098] The collinear arrangement of several central hinge shafts 3041 and their hinge connection to the finger beams 200 ensures uniformity of force transmission, enabling the finger beams 200 to move synchronously and smoothly. Compared to traditional structures, the variation in spacing between the finger beams 200 is reduced, effectively improving the stability of the variable finger beam system and ensuring reliable drill pipe storage.

[0099] The spacing of the finger beams 200 can be adjusted by extending and retracting the scissor-type telescopic frame 304, enabling high-precision control. Compared with traditional structures, the error in adjusting the spacing of the finger beams 200 is reduced, which can adapt to the storage requirements of drill pipes of different specifications, reduce the problem of drill pipe shaking or instability caused by inaccurate spacing, and improve the safety of drill pipe storage.

[0100] In some examples, such as Figure 4As shown, in the variable finger beam system using a scissor-type telescopic frame 304 as a synchronization component 300, the central hinge shaft 3041 is configured such that one end is rotatably fixed to the platform 100, while the other end slides and rotates, driven by the power head 302. This balances the stability and flexibility of adjusting the finger beam spacing. The fixed-end rotation provides a stable reference for the entire structure, while the combined configuration of the moving end, driven by the power head 302, enables the smooth extension and retraction of the scissor-type telescopic frame 304, thereby controlling the finger beam spacing to meet various drill pipe storage requirements.

[0101] When the spacing between the finger beams 200 needs to be increased, the drive device moves the power head 302 away from the fixed end, causing the central hinge shaft 3041 of the moving end to slide and rotate, the scissor telescopic frame 304 unfolds, the spacing between the other central hinge shafts 3041 increases, causing the finger beams 200 to move to both sides, increasing the spacing of the drill rod space 201, and the central hinge shaft 3041 of the fixed end ensures the stability of the unfolding.

[0102] When the spacing needs to be reduced, the drive device runs in reverse, the power head 302 moves closer to the fixed end, driving the hinge shaft 3041 in the middle of the moving end to slide and rotate in the opposite direction, the scissor telescopic frame 304 retracts, the finger beam 200 moves towards the middle, reducing the spacing of the drill rod space 201, and the hinge shaft 3041 in the middle of the fixed end ensures stable and accurate retraction.

[0103] The central hinge shaft 3041 enhances the stability of the finger beam 200 spacing adjustment, reduces adjustment errors, improves system reliability, and ensures accurate drill pipe storage spacing. The power head 302 drives the central hinge shaft 3041 at the moving end, allowing for more precise and flexible finger beam 200 spacing adjustment. The adjustment accuracy is improved compared to traditional methods, better adapting to various drill pipe storage needs and enhancing drill pipe storage safety and stability. This design ensures smooth extension and retraction of the scissor-type telescopic frame 304, reducing jamming resistance. The finger beam 200 spacing adjustment speed is increased compared to traditional structures, improving drill pipe management and drilling operation efficiency.
