Description

Technical Field

[0001] This utility model relates to the field of oil drilling technology, and in particular to a power finger beam assembly. Background Technology

[0002] As onshore oil exploration and development enters its mid-to-late stages, the industry is placing higher demands on the automation level of drilling equipment. In the oil and gas industry, components used to arrange drill pipes, drill collars, and other drilling tools are called finger beams, which are typically installed on the second-level platform of the derrick. Traditional finger beam operations rely on manual labor to push, move, and transport drilling tools on the second-level platform. This is not only extremely labor-intensive, but also presents a high risk due to the confined space and dangerous high-altitude environment on the second-level platform, exposing workers to safety risks such as falls and drill tool collisions.

[0003] To meet the demands of automated operations, the industry has developed various working modes for pipe laying machines. These machines use robotic arms to automatically grab and place drill bits. This transformation has also driven the need for simultaneous improvements to traditional finger beams to adapt to automated drill bit delivery processes. Currently, to achieve a compact layout and accommodate more drill bits, power finger beams generally use only one set of finger beam locks to control the entry and exit of drill bits within the gaps between adjacent sub-finger beams. Drill bits must be arranged sequentially along the same gap.

[0004] However, existing technologies have significant shortcomings in drill bit positioning and separation design, mainly falling into two categories: one category involves the absence of any damping measures, with the drill bit placed directly within the gap, leaving it in a state of free swaying. This not only makes it prone to tipping over under external forces such as strong winds, but also leads to chaotic spacing due to the lack of effective separation between drill bits; the other category employs a metal spring damping scheme, attempting to achieve drill bit positioning and separation through the elastic compression of the spring plates. However, the structural parameters of this scheme are fixed, and it can only be adapted to a single specification of drill pipe. When the specifications of the drill pipe used in actual operation do not match the preset specifications of the finger beam, both types of solutions will cause problems: the undamped solution, due to the lack of constraint, results in large amplitude of drill string sway and unstable spacing, making it difficult for the manipulator of the pipe laying machine to accurately align the drill string according to the pre-calibrated theoretical position, and frequent grasping failures occur; the metal spring plate damping solution will directly fail, as it cannot form effective compression constraint through the spring plate (damping effect is lacking), the drill string is prone to tipping over, and the spring plate cannot fit against the outer wall of the drill string, resulting in a reduction in the spacing between adjacent drill strings, which also interferes with the manipulator's grasping, seriously affecting the smoothness of drill string delivery and prolonging the drilling cycle.

[0018] (III) Beneficial Effects

[0019] The beneficial effects of this utility model are:

[0020] This utility model provides a power finger beam assembly. Through the cooperation of multiple parallel finger beam assemblies and supports, multiple elastic damping components evenly arranged along the length of the sub-finger beams form independent drill bit arrangement positions within the drill bit arrangement space formed by adjacent sub-finger beams. This not only allows the flexible deformation of the elastic damping components to adapt to drill bits of different specifications (diameter differences), solving the damping failure problem caused by traditional metal spring damping which only adapts to a single specification, but also utilizes elastic force to provide stable constraint on the drill bit, avoiding the free swaying phenomenon of the drill bit in undamped solutions, and effectively preventing the drill bit from tipping over under external forces (such as strong winds); simultaneously, multiple elastic damping components divide the same drill bit arrangement space into multiple independent drill bit arrangement positions, ensuring the spacing between adjacent drill bits. Uniform and stable spacing prevents the failure of the manipulator to grasp the drill string at the preset position due to chaotic spacing, ensuring smooth automated operation. The power finger lock at the free end of the sub-finger beam opens and closes the drill string arrangement space horizontally, with its switching action not interfering with the drill string loading and unloading path, making operation more flexible and efficient. Furthermore, the structural design of multiple finger beam assemblies arranged parallel to the support, with one end of the sub-finger beam fixed to the support, achieves a compact layout of the drill string and distributes the load through the support, avoiding deformation caused by concentrated stress on the sub-finger beam. The overall design is adapted to the needs of automated pipe laying machine operations, reducing manual intervention and lowering the risks of high-altitude operations. It also improves drill string positioning stability, specification adaptability, and operational efficiency, solving the core pain points of traditional finger beams in automated scenarios. Compared to existing technologies, through functional integration and structural optimization, it significantly improves the automation adaptability and overall operational performance of the power finger beam assembly, providing reliable drill string storage and transportation guarantees for efficient drilling in the mid-to-late stages of oil exploration and development.

[0034] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0035] Example 1:

[0036] like Figures 1-3 As shown, this embodiment provides a power finger beam assembly, including a support 1 and multiple finger beam assemblies; the multiple finger beam assemblies are arranged in parallel on the support 1; each finger beam assembly includes a sub-finger beam 21, multiple elastic damping components, and a power finger beam lock; one end of the sub-finger beam 21 is installed on the support 1; the multiple elastic damping components are evenly arranged along the length of the sub-finger beam 21; the power finger beam lock is installed on the free end of the sub-finger beam 21; a drill string arrangement space is formed between two adjacent sub-finger beams 21, and the multiple elastic damping components on two adjacent sub-finger beams 21 form multiple drill string arrangement positions within the drill string arrangement space; the power finger beam lock can open and close the drill string arrangement space in the horizontal direction.

[0037] Specifically, through the cooperation of multiple parallel finger beam assemblies with support 1, multiple elastic damping components evenly arranged along the length of the sub-finger beams 21 form independent drill bit arrangement positions within the drill bit arrangement space formed by adjacent sub-finger beams 21. This not only allows the flexible deformation of the elastic damping components to adapt to drill bits of different specifications (diameter differences), solving the damping failure problem caused by traditional metal spring damping only adapting to a single specification, but also utilizes elastic force to form a stable constraint on the drill bit, avoiding the free swaying phenomenon of the drill bit in the undamped scheme, and effectively preventing the drill bit from tipping over under the action of external forces (such as strong winds); at the same time, multiple elastic damping components divide the same drill bit arrangement space into multiple independent drill bit arrangement positions, ensuring that the spacing between adjacent drill bits is uniform and stable, and avoiding the influence of external forces (such as strong winds). The problem of inconsistent spacing causing the manipulator of the pipe laying machine to fail to grasp the drill string at the preset position is addressed, ensuring the smooth operation of automated work. The power finger lock at the free end of the sub-finger beam 21 opens and closes the drill string arrangement space horizontally, with its switching action not interfering with the drill string loading and unloading path, making operation more flexible and efficient. Furthermore, the structural design of multiple finger beam assemblies arranged parallel to support 1, with one end of the sub-finger beam 21 fixed to support 1, achieves a compact layout of the drill string and distributes the load through support 1, avoiding deformation caused by concentrated stress on the sub-finger beam 21. This overall design is adapted to the operational needs of automated pipe laying machines, reducing manual intervention, lowering the risks of high-altitude operations, and improving drill string positioning stability, specification compatibility, and operational efficiency, thus solving the core pain points of traditional finger beams in automated scenarios. Compared to existing technologies, through functional integration and structural optimization, it significantly improves the automation adaptability and overall operational performance of the power finger beam assembly, providing reliable drill string storage and transportation guarantees for efficient drilling in the mid-to-late stages of oil exploration and development.

[0038] Furthermore, such as Figures 1-3 As shown, the elastic damping assembly includes an elastic non-metallic damping plate 22 and a mounting assembly; the elastic non-metallic damping plate 22 is detachably mounted on the sub-finger beam 21 via the mounting assembly. By designing the elastic damping assembly as an elastic non-metallic damping plate 22 and a detachable mounting assembly, the problems of poor adaptability and difficult maintenance of traditional metal spring damping are specifically addressed: compared to metal springs, the elastic non-metallic damping plate 22 has a larger range of flexible deformation and can conform to the outer wall of drill bits of different specifications through its own elasticity, avoiding the defects of metal springs either being too tight and squeezing the drill bit or too loose and losing damping; the detachable mounting assembly allows the damping plate to be replaced individually after wear or aging, shortening maintenance time and reducing equipment maintenance costs; at the same time, the friction coefficient of non-metallic materials is more stable when in contact with the drill bit, which can provide sufficient constraint to prevent the drill bit from sliding and avoid rigid collisions between metal and the drill bit, reducing scratches on the drill bit surface.

[0039] Furthermore, such as Figures 1-7As shown, the mounting assembly includes a pressure plate 23 and at least two fastening bolts 24; the elastic non-metallic damping sheet 22 has two first through holes 25, and the pressure plate 23 has two second through holes 26; the pressure plate 23 is positioned above the elastic non-metallic damping sheet 22, and the two second through holes 26 are respectively connected to the two first through holes 25 to form two mounting holes, and the two fastening bolts 24 pass through the two mounting holes and are threaded to the sub-finger beam 21. The pressure plate 23 covers the elastic non-metallic damping plate 22, which can evenly transmit the pressure of the fastening bolt 24 to the elastic non-metallic damping plate 22, avoiding local stress deformation of the damping plate caused by a single bolt fixation, and ensuring the fit between the damping plate and the drill string; the double fastening bolts 24 are symmetrically distributed (the spacing is adapted to the size of the damping plate), which significantly enhances the connection strength compared with single bolt fixation, preventing the damping plate from loosening and falling off due to drilling vibration; in addition, the first through hole 25 and the second through hole 26 are precisely aligned to form the installation hole, eliminating the need for repeated calibration during assembly, significantly improving installation efficiency, and the bolt thread connection method facilitates disassembly and assembly by hand or simple tools, further reducing the difficulty of maintenance operations, and is suitable for the operation scenario of the narrow space of the second-level platform of the derrick.

[0040] Furthermore, such as Figures 4-6 As shown, the elastic non-metallic damping sheet 22 includes an integrally formed mounting portion 221 and two elastic limiting portions 222; the two elastic limiting portions 222 are symmetrically located on both sides of the mounting portion 221. The one-piece molding design eliminates the splicing gap between the mounting part 221 and the limiting part, avoiding the breakage or separation problems that are easily caused by vibration and extrusion in the split structure. This significantly enhances the overall structural strength and fatigue resistance of the elastic non-metallic damping plate 22, and extends its service life. On the other hand, the two symmetrically distributed elastic limiting parts 222 cooperate with the elastic limiting parts 222 of the adjacent elastic damping components to form an enclosed constraint space from both sides of the drill bit. When the drill bit is placed in this space, the elastic limiting parts 222 on both sides can fit against the outer wall of the drill bit through their own elastic deformation. This not only provides precise positioning for the drill bit and prevents it from shifting in the horizontal direction, but also uses elastic force to buffer the impact of external forces on the drill bit (such as the impact when the drill bit is lowered, the shaking caused by strong winds, etc.), further improving the stability of the drill bit on the finger beam. At the same time, the one-piece molding structure also makes the production and assembly of the damping plate simpler, reduces assembly steps, and improves installation and maintenance efficiency.

[0041] Furthermore, in this embodiment, the elastic limiting part 222 is trapezoidal in shape. The inclined side of the trapezoid has a guiding function, allowing the drill bit to slide along the inclined side into the center of the limiting part when it is lowered, thus preventing the drill bit from getting stuck at the edge of the damping plate. The trapezoidal structure, which is narrower at the top and wider at the bottom, makes the bottom of the elastic limiting part 222 stronger, enabling it to withstand the impact load when the drill bit is lowered (it is not easy to break even when faced with a large impact), thus preventing the limiting part from being damaged due to concentrated force. At the same time, the trapezoidal structure has better deformation uniformity, and the force is more even when the drill bit is in contact with the elastic limiting part 222, reducing local wear and extending the service life after a single replacement.

[0042] Furthermore, such as Figure 6 As shown, from the main viewpoint, the elastic non-metallic damping sheet 22 includes a first rubber layer 27, a polyester filament layer 28, and a second rubber layer 29 arranged sequentially from top to bottom. The upper and lower rubber layers provide flexible deformation and damping force, ensuring the fit and restraint effect with the drill string; the middle polyester filament layer 28 can enhance the tensile and tear resistance of the damping sheet, avoiding the tearing and damage caused by the frequent compression of the drill string in traditional single rubber sheets; the composite structure can also reduce the aging rate of the damping sheet, the rubber layer isolates external dust and oil, and the polyester filament layer 28 slows down the creep of the rubber, which greatly extends the service life of the damping sheet in the drilling environment; in addition, the damping coefficient of the composite structure is more stable (with small changes after long-term use), ensuring consistent positioning effect for drill strings of different specifications and avoiding spacing chaos caused by changes in the damping coefficient.

[0043] Furthermore, such as Figure 8 and Figure 9As shown, the power finger beam lock includes a lock seat 31, a locking tongue 32, and a servo driver 33. The lock seat 31 is installed at the end of the sub-finger beam 21. The locking tongue 32 is rotatably installed on the lock seat 31. The servo driver 33 is installed on the lock seat 31. The servo driver 33 is connected to the locking tongue 32 to drive the locking tongue 32 to rotate in a vertical plane, thereby opening and closing the drill string arrangement space. The rotation of the locking tongue 32 in the vertical plane achieves opening and closing. Compared with traditional vertical pins, the locking path is shorter, and the single opening and closing time is significantly reduced. The servo driver 33 precisely controls the rotation angle of the locking tongue 32 (with minimal deviation), avoiding incomplete locking or excessive rotation of the locking tongue 32, significantly improving the locking success rate. At the same time, the rotating locking tongue 32 does not occupy the drill string arrangement space, adapting to the narrow vertical space of the second-level platform of the derrick, and the rotation path of the locking tongue 32 does not interfere with the drill string loading and unloading path, avoiding the risk of collision with the drill string and ensuring the smoothness of automated operation. In this embodiment, the servo driver 33 is located inside the sub-finger beam 21. Drilling sites present risks such as dust, oil, and drill string collisions. The built-in design isolates external contaminants, preventing short circuits or mechanical damage to the servo drive 33 and extending the lifespan of electrical components. Built-in installation eliminates the need for external space for the servo drive 33 on the sub-finger beam 21, resulting in a more compact overall structure that accommodates densely packed multiple finger beam assemblies (allowing for more finger beam assemblies to be arranged within the same space). Furthermore, the sub-finger beam 21 provides a stable heat dissipation environment (preventing drastic temperature fluctuations caused by sun and rain), ensuring stable operation of the servo drive 33 under varying ambient temperatures and further enhancing the reliability of the locking action.

[0044] Specifically, based on the detachable elastic non-metallic damping plate 22, the combination of the pressure plate 23 and double fastening bolts 24 ensures that the elastic non-metallic damping plate 22 is installed firmly and subjected to uniform force, avoiding local deformation. The integrally formed mounting part 221 and the symmetrical elastic limiting parts 222 on both sides form an integral structure, which improves the fracture resistance and forms bidirectional constraints from both sides of the drill bit. The trapezoidal elastic limiting part 222 optimizes the guiding effect, reduces drill bit jamming, and enhances impact resistance. The composite layer structure improves the tear resistance and aging resistance of the elastic non-metallic damping plate 22 and maintains a stable damping coefficient. These structures work together to form a damping system with a wide range of adaptability, stable positioning, easy maintenance, and long service life. Compared with traditional metal spring plate damping, it can better adapt to different specifications of drill bits, reduce drill bit swaying and spacing confusion, and make maintenance and operation more convenient.

[0045] Specifically, the power finger lock, composed of the rotating locking tongue 32 and the servo driver 33, achieves rapid opening and closing through the rotation of the locking tongue 32 in the vertical plane, saving space and avoiding interference with the drill string loading and unloading path. The design of the servo driver 33 being built into the sub-finger beam 21 improves protection performance, reduces failures, and optimizes structural compactness. The sub-finger beam 21 provides a flat mounting base for the elastic non-metallic damping components, while its internal cavity can accommodate the built-in servo driver 33, achieving structural integration. The combination of these three components enables the power finger lock to combine small size and high reliability, forming a stable positioning-locking integrated function with the sub-finger beam 21, adapting to the rapid gripping requirements of automated pipe handling machines and making drill string loading and unloading smoother.

[0046] In this embodiment, the power finger beam assembly is used as follows: After the pipe-laying robot grabs the drill bit and reaches the vicinity of the power finger beam assembly, the servo driver 33 of the power finger beam lock drives the locking tongue 32 to rotate in the vertical plane, opening the drill bit arrangement space. Subsequently, the pipe-laying robot carries the drill bit to the position above the corresponding drill bit arrangement position and slowly lowers the drill bit. The symmetrical elastic limiting part 222 of the adjacent elastic damping component relies on its own elastic deformation to adhere to the outer wall of the drill bit from both sides around the circumference, forming an enclosed constraint to position the drill bit. The inclined side of the trapezoidal elastic limiting part 222 can guide the drill bit to slide smoothly into the center position, avoiding jamming. After the drill bit is stably placed, the power finger beam lock is activated again, and the locking tongue 32 rotates to close the drill bit arrangement space, preventing the drill bit from tipping over or shifting under the action of external forces (such as strong winds or equipment vibration). When drill string needs to be retrieved, the power finger beam lock opens first, and the pipe-laying robot extends into the drill string arrangement space to grasp the drill string. The elastic limiting part 222 of the elastic damping assembly returns to its original shape as the drill string is retrieved, ready for the placement of the next drill string. If the elastic non-metallic damping plate 22 wears or ages due to long-term use, it can be quickly replaced by removing the fastening bolts 24 and the pressure plate 23. The entire maintenance process does not require disassembling the sub-finger beam 21 and can be easily operated even in the confined space of the second-level platform of the derrick. Through this operation process, the power finger beam assembly achieves stable storage, positioning, and efficient loading and unloading of drill strings, significantly reducing the risks of high-altitude operations, while improving the smoothness and automation level of drill string transportation operations, meeting the high requirements for automation of drilling equipment in the mid-to-late stages of oil exploration and development.

[0047] Example 2:

[0048] This embodiment provides a system that includes all the structures of the power finger beam assembly described in Embodiment 1.

[0049] In this embodiment, the sub-finger beam 21 has a rectangular cross-sectional shape. The rectangular cross-section is simple to process (compared to I-shaped and trapezoidal cross-sections, it is easier and more cost-effective to process), and the external plane is flat, which facilitates the stable installation of the elastic damping components by bolts (avoiding the tilting and uneven fitting of the damping plates caused by non-planar installation); the rectangle has a large cavity inside, which can accommodate the built-in servo driver 33 (without the need to open an additional mounting slot), realizing structural integration; at the same time, the rectangular cross-section has better stress uniformity. When the weight of the drill bit is transferred to the sub-finger beam 21 through the damping plates, the rectangular structure can distribute the load to the entire beam (significantly alleviating stress concentration), avoiding the bending deformation caused by excessive local stress in traditional irregular cross-sections, and ensuring the structural stability of the sub-finger beam 21 under long-term load.

[0050] Specifically, the elastic damping assembly ensures stable positioning and uniform spacing of drill bits of different specifications through flexible deformation and bidirectional constraint; the power finger beam lock prevents drill bits from tipping over and ensures safety through a rotating locking tongue 32 and precise drive; the rectangular-section sub-finger beam 21 provides a stable load-bearing and integrated installation foundation, distributing loads to avoid deformation. These structures, combined with multiple parallel finger beam assemblies, allow for the stable accommodation of more drill bits of different specifications within the same drill bit arrangement space. Furthermore, the entire process from positioning to locking requires no manual intervention, completely replacing traditional manual pushing operations, significantly reducing the risks of high-altitude operations, and meeting the automated and efficient drilling needs of the mid-to-late stages of oil exploration.
