Description

Technical Field

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

[0002] In drilling operations, finger beams are installed on the second tier of the derrick. Resembling orderly arranged "fingers," they are composed of multiple parallel metal rods or beams. One end of these finger beams is securely connected to the second tier's structural frame, while the other end is naturally suspended. During actual operations, as the drilling depth changes, drill pipes need to be frequently hauled in and out. The finger beams serve as temporary and orderly storage locations for the drill pipe posts, allowing drillers to efficiently manage them. For example, during drill pipe hauling operations, when situations arise such as drill bit wear requiring replacement, core sampling, or staged drilling table installation, the drill pipe retrieved from the well is neatly placed on the finger beams. When drilling needs to continue, the driller can easily grab the drill pipe from the finger beams for connection operations. Simultaneously, the finger beams effectively restrain the drill pipes, reducing the safety risks caused by swaying and swinging at the second tier, ensuring safe and orderly operation. In existing technologies, the limiting effect of finger beams on drill pipes is relatively simple, or even if some structures limit the finger beams, they are complex, inconvenient to install and disassemble, and some require driving components, thus increasing costs. Utility Model Content

[0003] To overcome the above-mentioned defects, the embodiments of this disclosure provide a two-layer platform finger beam lock and a two-layer platform, which solves the technical problems of the drill pipe limiting structure next to the finger beam of the two-layer platform of the derrick in the prior art, which has complex structure, inconvenient installation and disassembly, and high cost.

[0004] According to one aspect, at least one embodiment of this disclosure provides a two-layer pedestal finger beam lock, comprising:

[0005] A base for mounting on a finger beam;

[0006] A lock head, which is movable and / or oscillatingly mounted on the base;

[0007] A spring element, one end of which acts on the base and the other end of which acts on the lock head, providing a force to the lock head away from the base;

[0008] The base has a first limiting part, the lock head has a second limiting part, and the spring is configured such that the first limiting part abuts against the second limiting part.

[0009] For example, at least one embodiment of this disclosure provides a two-tiered finger-beam lock, wherein the base has a cylindrical groove, the lock head has a cylindrical guide, and the cylindrical guide is slidably disposed within the cylindrical groove.

[0010] For example, at least one embodiment of this disclosure provides a two-layer pedestal finger beam lock, wherein there are two cylindrical guides and two cylindrical slots, which are arranged symmetrically.

[0011] For example, at least one embodiment of this disclosure provides a two-tiered finger-beam lock, wherein the cylindrical guide has a receiving space, and the spring is located within the receiving space and the cylindrical groove.

[0012] For example, at least one embodiment of this disclosure provides a two-layer pedestal finger beam lock, wherein the lock head has a screw portion, the first limiting portion has a through hole, the screw portion passes through the through hole, and the second limiting portion is threaded onto the screw portion.

[0013] For example, at least one embodiment of this disclosure provides a two-layer pedestal finger beam lock, which further includes:

[0014] The housing, the base, the first limiting part, the second limiting part and the screw part are all located inside the housing.

[0015] For example, at least one embodiment of this disclosure provides a two-tiered finger-beam lock, wherein the lock head has an arc-shaped limiting portion at the end away from the base.

[0016] The second-floor platform, including the aforementioned second-floor platform finger beam lock, also includes:

[0017] Platform;

[0018] The finger beams are arranged in sequence, and a row of drill rods is accommodated between two adjacent finger beams. Several double-layer finger beam locks are arranged in sequence on one or both sides of the finger beams, and a drill rod is accommodated between two adjacent double-layer finger beam locks.

[0019] For example, at least one embodiment of this disclosure provides a two-tier platform, wherein the two-tier platform finger beam lock is disposed on the top surface of the finger beam.

[0020] For example, at least one embodiment of this disclosure provides a two-tier platform, which includes a first platform body and a second platform body, the first platform body and the second platform body are connected and disposed together, and a row of finger beams is provided on both the first platform body and the second platform body.

[0021] The beneficial effects of the embodiments disclosed herein are as follows:

[0022] In this disclosure, the two-layer platform finger beam lock, through the cooperation of the base, lock head, and spring component, utilizes the elastic force provided by the spring component to maintain a certain positional relationship between the lock head and the base under normal conditions, and is maintained stable by the abutment of the first and second limiting parts. When the drill rod enters, the drill rod squeezes the lock head to overcome the spring force, causing the lock head to move or swing. After the drill rod passes, the spring resets, driving the lock head back to its initial position, realizing automatic locking and unlocking of the drill rod. No additional drive components are required, simplifying the structure and reducing costs. Attached Figure Description

[0028] 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.

[0033] 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.

[0034] like Figure 1As shown, this is an embodiment of a two-layer pedestal finger beam lock. Through the cooperation of the base 100, the lock head 200, and the spring member 300, the spring member 300 provides elasticity, allowing the lock head 200 to maintain a certain position relative to the base 100 under normal conditions. Stability is maintained by the contact of the first limiting part 101 and the second limiting part 201. When a drill rod enters, the drill rod presses against the lock head 200, overcoming the spring force, causing the lock head 200 to move or swing. After the drill rod passes, the spring resets, returning the lock head 200 to its initial position, thus achieving automatic locking and unlocking of the drill rod. This eliminates the need for additional drive components, simplifying the structure and reducing costs.

[0035] In some examples, the base 100 is designed to be flat for mounting on the finger beam. A first limiting part 101 is located on the side of the base 100 near the lock head 200, and its shape is adapted to the second limiting part 201. The base 100 is mounted on the finger beam by bolts or welding. When bolted, the base 100 has mounting holes, and the corresponding finger beam has threaded holes; when welded, the side of the base 100 that contacts the finger beam is beveled.

[0036] The lock head 200 has an arc-shaped head, and the second limiting part 201 is located on the side of the lock head 200 near the base 100, cooperating with the first limiting part 101. If the lock head 200 is movable, the base 100 has a sliding groove, and the bottom of the lock head 200 has a slider; if it is swingable, the base 100 is equipped with a pin, and the lock head 200 is hinged to the base 100 through the pin; a combination of movable and swingable methods can also be used.

[0037] The spring component 300 is a compression spring, with one end abutting against the spring mounting seat on the base 100 and the other end abutting against the spring connecting part of the lock head 200.

[0038] Initially, the spring 300 extends naturally, pushing the locking head 200 so that the second limiting part 201 abuts against the first limiting part 101, forming a space between the four locking heads 200 to restrict the drill rod. When the drill rod enters, it presses against the locking head 200, causing the locking head 200 to move or swing against the elastic force of the spring 300. After the drill rod passes, the spring 300 drives the locking head 200 to reset, restricting the drill rod again. Multiple finger-beam locks are installed on each finger beam to hold multiple drill rods arranged in sequence.

[0039] The two-layer platform finger beam lock uses a simple combination of base 100, lock head 200 and spring 300. It does not have complex drive components and complicated structural design, which reduces costs compared with existing technologies, reduces potential failures, and improves equipment reliability.

[0040] Whether installed using a bolted, detachable base or a welded, fixed installation, it offers high operability. Installation and disassembly time is reduced compared to existing complex structures, improving maintenance efficiency.

[0041] The spring element 300 enables automatic locking and unlocking of the lock head 200, providing rapid response to drill pipe entry and exit without manual operation of the lock, thus improving drill pipe management efficiency. The lock head 200 and the base 100 are tightly abutted by the first limiting part 101 and the second limiting part 201, and the lock head 200 moves or swings precisely on the base 100, effectively limiting drill pipe swaying and swinging, reducing safety risks, and ensuring the safe and orderly conduct of drilling operations.

[0042] In some examples, such as Figure 1 As shown, the cylindrical groove 102 of the base 100 and the cylindrical guide 202 of the lock head 200 cooperate with each other to optimize the movement of the lock head 200 on the base 100. This structure provides guidance for the movement of the lock head 200, ensuring that it maintains a stable linear motion trajectory when moved by the drill pipe and reset by the spring 300. The guide improves the accuracy of the lock head 200 in limiting the drill pipe, reduces the risk of drill pipe swaying or disengagement, and enhances the stability and reliability of the two-layer platform finger beam lock.

[0043] The cylindrical grooves 102 are formed on both sides of the base 100 near the lock head 200, with their axial direction consistent with the moving direction of the lock head 200. The number of them depends on the structure and stability requirements of the lock head 200, and can be 1-2. If the lock head 200 is small and compact, one is provided; if the lock head 200 is large or requires higher stability, two cylindrical grooves 102 are symmetrically distributed on both sides of the moving path of the lock head 200.

[0044] The inner wall surface of the cylindrical groove 102 is smooth to reduce the sliding friction of the cylindrical guide 202. The groove depth ensures that the cylindrical guide 202 does not come out, and the diameter fits tightly with the cylindrical guide 202 with proper clearance control to ensure smooth sliding of the cylindrical guide 202 and maintain good guidance.

[0045] The cylindrical guide 202 is integrally formed with the lock head 200 to ensure connection strength and prevent loosening and separation under operational vibration and impact. The cylindrical guide 202 protrudes from the surface of the lock head 200 near the base 100. Its length is determined according to the depth of the cylindrical groove 102 and the moving stroke of the lock head 200, and is slightly shorter than the depth of the cylindrical groove 102 to ensure movement space and not affect the structural stability of the lock head 200.

[0046] When no drill rod is inserted, the spring 300 extends naturally, pushing the locking head 200 so that the second limiting part 201 tightly abuts against the first limiting part 101. At this time, the cylindrical guide part 202 is located in the cylindrical groove 102 near the bottom of the groove, the two-layer platform finger beam lock is in the locked state, and the space between the two locking heads 200 restricts the drill rod.

[0047] The drill pipe enters between the two locking heads 200, pressing against the locking heads 200, which then move against the elastic force of the spring member 300. During this movement, the cylindrical guide 202 slides along the inner wall of the cylindrical groove 102. Due to the guidance of the cylindrical groove 102, the locking head 200 maintains stable linear movement, allowing the drill pipe to pass smoothly through the enlarged space.

[0048] After the drill pipe passes through, the spring 300 returns to its natural extension, causing the locking head 200 to reset. Under the action of the spring force, the cylindrical guide 202 slides back to its initial position along the cylindrical groove 102, and the second limiting part 201 tightly abuts against the first limiting part 101 again, restricting the drill pipe again and completing the locking and unlocking process.

[0049] The cylindrical groove 102 cooperates with the cylindrical guide 202 to reduce the movement deviation of the locking head 200 and better restrict the position of the drill pipe. This reduces the shaking of the drill pipe caused by positional deviation.

[0050] The guide structure enhances the stability of the connection between the lock head 200 and the base 100. During operation, it can better withstand the impact and vibration of the drill pipe, reducing the risk of displacement or damage to the lock head 200, extending the service life of the second-layer platform finger beam lock, and lowering the failure rate caused by vibration.

[0051] The cylindrical guide 202 slides smoothly within the cylindrical groove 102, ensuring stable movement of the locking head 200. This allows for quick and stable retraction of the locking head 200 during drill rod insertion and resetting after drill rod passage. This optimizes the smoothness of the two-layer platform finger beam lock operation, improves drill rod retrieval and placement efficiency, and shortens drill rod operation time.

[0052] In some examples, such as Figure 1 As shown, two cylindrical guide sections 202 and two cylindrical grooves 102 are arranged symmetrically. This design aims to further improve the stability of the lock head 200's movement on the base 100 and the reliability of its limit on the drill pipe. The symmetrically distributed double cylindrical guide sections 202 and cylindrical grooves 102 structure can provide balanced and stable guiding force to the lock head 200 from both sides during the process of the lock head 200 being squeezed by the drill pipe and reset by the spring member 300, effectively preventing the lock head 200 from deviating, tilting, or getting stuck during movement. This not only ensures that the drill pipe can be more accurately restricted between the two lock heads 200, but also enhances the stability and adaptability of the entire two-layer platform finger beam lock in dealing with various complex working conditions in drilling operations, thereby ensuring the safety and efficiency of drilling operations.

[0053] In some examples, such as Figure 1As shown, placing the spring element 300 within the receiving space 2021 of the cylindrical guide 202 and the cylindrical groove 102 optimizes the structure and function of the two-layer finger beam lock. On one hand, this layout makes the lock structure more compact, allowing for a more rational arrangement of components within a limited installation space. On the other hand, it better protects the spring element 300 from damage caused by external environmental factors such as dust and mud during drilling operations, ensuring long-term stable operation of the finger beam lock and reliable limit of the drill pipe.

[0054] The accommodating space 2021 is inside the cylindrical guide 202, extending axially from the end near the lock head 200, and is cylindrical in shape. Its size is adapted to accommodate the spring 300, and its depth meets the extension and retraction requirements of the spring 300.

[0055] First, place one end of the spring 300 into the positioning groove at the bottom of the cylindrical groove 102, and then align and insert the cylindrical guide 202 with the receiving space 2021 to ensure that the spring 300 extends naturally and coincides with the axis.

[0056] In the initial state, the spring 300 naturally extends and abuts against the bottom of the cylindrical groove 102 and the bottom of the receiving space 2021, locking the locking head 200 to the base 100. When the drill rod presses against the locking head 200, the spring 300 is compressed into the receiving space 2021. After the drill rod passes through, the spring 300 resets, and the locking head 200 returns to the locked state, completing the drill rod limiting.

[0057] The cylindrical groove 102 serves both as a guide for the cylindrical guide 202 and, together with the receiving space 2021, accommodates the spring 300. Its depth ensures the normal operation of the cylindrical guide 202 and the spring 300, and the appropriate gap between the inner wall and the outer wall of the cylindrical guide 202 ensures smooth sliding and limits oscillation.

[0058] The cylindrical groove 102 is manufactured as an integral part of the base 100, and works in conjunction with the accommodating space 2021 and the spring component 300 to achieve stable movement of the lock head 200 and reliable limit of the drill rod, ensuring the normal operation of the second-floor platform finger beam lock.

[0059] The built-in spring component 300 makes the double-layer platform finger beam lock structure more compact. Compared with the external spring component structure, the overall volume is reduced, making it more suitable for installation in the limited space of the double-layer platform finger beam and improving space utilization.

[0060] The spring element 300 is protected by the accommodating space 2021 and the cylindrical groove 102, reducing the risk of external corrosion damage. In actual working environments, it extends service life, reduces maintenance costs, and improves operational reliability.

[0061] The aforementioned structure ensures more even and stable force distribution on the spring component 300, improving the smooth movement of the locking head 200 and the reliability of the drill rod's positioning. Compared to traditional structures, the locking head 200 exhibits less wobbling, the drill rod is more securely fixed, safety hazards are reduced, and operational safety is guaranteed.

[0062] In some examples, such as Figure 1 As shown, the screw portion 203 of the lock head 200 passes through the through hole 1011 of the first limiting portion 101, and the second limiting portion 201 is threaded onto the screw portion 203. This design brings new characteristics to the connection and limiting method between the lock head 200 and the base 100. This structure makes the connection between the lock head 200 and the base 100 more stable. Through the threaded engagement, the second limiting portion 201 can be finely adjusted on the screw portion 203 to adapt to the limiting requirements of drill rods of different specifications. At the same time, the threaded connection method, while ensuring connection strength, facilitates flexible adjustment of the position and limiting force of the lock head 200 during installation, debugging, and maintenance, improving the versatility and maintainability of the two-layer platform finger beam lock.

[0063] The screw portion 203 of the lock head 200 protrudes from the side of the lock head 200 near the base 100. Its shape can be cylindrical, and its surface is threaded. The thread specification is determined based on the size of the lock head 200, the force it withstands, and the mating requirements with the second limiting portion 201. Generally, a metric coarse thread is used to ensure sufficient connection strength and ease of adjustment. The length of the screw portion 203 must be sufficient to pass through the through hole 1011 of the first limiting portion 101, and the protruding portion must have sufficient length for threaded connection and adjustment with the second limiting portion 201.

[0064] The screw section 203 and the locking head 200 are manufactured using an integral molding process to ensure that they have sufficient strength to withstand various forces on the locking head 200 during drilling operations, thus preventing the screw section 203 and the locking head 200 from separating during use.

[0065] The through hole 1011 of the first limiting part 101 is located at the center of the first limiting part 101. It is circular in shape and its diameter is slightly larger than the outer diameter of the screw part 203 to ensure that the screw part 203 can pass through smoothly. The inner wall of the through hole 1011 is processed to make the surface smooth, so as to reduce the friction when the screw part 203 passes through, while ensuring that the screw part 203 can rotate freely in the through hole 1011, which facilitates the subsequent adjustment of the second limiting part 201 on the screw part 203.

[0066] When the second limiting part 201 is a round nut, its inner diameter is machined with an internal thread that matches the screw part 203. The outer diameter is determined according to actual operation and limiting requirements, and is generally larger than the diameter of the through hole 1011 to facilitate the operator's use of tools for tightening and loosening operations. The thickness of the round nut is determined according to the required force and adjustment range to ensure that it can provide sufficient limiting force for the locking head 200 after tightening, preventing the locking head 200 from loosening during operation.

[0067] When installing or debugging the double-layer finger-beam lock, first pass the screw part 203 of the lock head 200 through the through hole 1011 of the first limiting part 101, and then tighten the round nut, i.e., the second limiting part 201, onto the screw part 203. By rotating the round nut, its position on the screw part 203 can be adjusted, thereby changing the relative position and limiting force between the lock head 200 and the base 100. When it is necessary to limit drill pipes of different specifications, the position of the round nut can be adjusted appropriately according to the size of the drill pipe, so that the lock head 200 can better adapt to the limiting requirements of the drill pipe. During drilling operations, after the round nut is tightened, the self-locking characteristic of the thread maintains the limiting effect on the lock head 200, ensuring that the double-layer finger-beam lock can stably limit the drill pipe.

[0068] The engagement of the screw section 203 with the through hole 1011 and the threaded connection of the second limiting section 201, compared to traditional connection methods, improve the connection strength between the locking head 200 and the base 100. Under the vibration and impact conditions of drilling operations, this ensures the locking head 200 maintains its position more reliably, reducing the risk of drill pipe limiting failure due to loose connections and guaranteeing the safety of drilling operations.

[0069] By adjusting the position of the second limiting part 201 on the screw part 203, the distance and limiting force between the lock head 200 and the base 100 can be flexibly adjusted, enabling the two-layer finger beam lock to adapt to the limiting requirements of various drill rod specifications. Compared with the traditional fixed limiting structure, its versatility is improved, reducing the need to replace the entire finger beam lock due to changes in drill rod specifications, and lowering the cost of use.

[0070] The threaded connection allows operators to easily disassemble and install the lock head 200 for inspection, repair, or replacement during the installation, commissioning, and maintenance of the second-level platform finger beam lock. Compared to some complex connection structures, this reduces maintenance and commissioning time, improves equipment maintainability, minimizes downtime due to equipment maintenance, and increases drilling operation efficiency.

[0071] In some examples, such as Figure 1 As shown, a housing 400 is added to the two-layer finger beam lock, and the base 100, the first limiting part 101, the second limiting part 201, and the screw part 203 are placed inside. The housing 400 provides protection for the internal components, preventing dust, mud, and other impurities during drilling operations from affecting the performance of the components, thereby extending their service life. At the same time, it helps to integrate the internal structure, making the entire finger beam lock structure more compact and orderly, facilitating installation, disassembly, and maintenance. Furthermore, the housing 400 can also reduce noise generated by friction and vibration between components to a certain extent, optimizing the working environment.

[0072] The housing 400 is designed to fit the shape of a double-layer finger shank lock, generally being flat to conform to the installation space of the finger shank. The housing 400 has specific openings for installing and operating internal components, and also features a structure for connecting to the finger shank, ensuring a secure mounting of the lock onto the finger shank. The base 100 is fixed within the housing 400 and connected to the inner wall of the housing 400 in a suitable manner, ensuring its stable position within the housing and preventing displacement due to vibration.

[0073] During drilling operations, the drill pipe presses against the locking head 200. The locking head 200 moves within the housing through the engagement of the screw part 203 and the second limiting part 201, overcoming the elastic force of the spring component. After the drill pipe passes through, the locking head 200 returns to its limit position under the action of the spring component. During this process, the housing 400 blocks impurities, ensuring the normal operation of internal components. For maintenance, opening the opening or cover on the housing 400 allows for convenient inspection, repair, or replacement of internal components.

[0074] The housing 400 effectively blocks impurities, reduces component wear and corrosion, and significantly extends the service life of each component. The housing 400 integrates the internal structure, making the finger lock structure more compact and maintenance operations more convenient, reducing downtime caused by maintenance and improving work efficiency. The housing 400 also blocks noise generated by internal components, improving the comfort of the working environment and reducing the harm of noise to operators.

[0075] In some examples, such as Figure 1 As shown, an arc-shaped limiting part 204 is provided at the end of the lock head 200 away from the base 100, thereby optimizing the process of the drill rod entering the second-layer platform finger beam lock. The arc-shaped design can play a guiding role. When the drill rod approaches the lock head, the arc-shaped limiting part 204 can guide the drill rod smoothly into the limiting space between the two lock heads 200. This not only improves the efficiency of drill rod placement, but also reduces the collision damage that may be caused by hard contact between the drill rod and the lock head, ensuring that the drill rod enters more smoothly and stably, and improving the limiting effect and service life of the entire second-layer platform finger beam lock on the drill rod.

[0076] The arc-shaped limiting part 204 is a smooth arc. Its curvature is designed according to the diameter of the drill rod. It is generally advisable to fit the outer surface of the drill rod to ensure that the drill rod can be naturally guided into the arc-shaped limiting part 204 when it comes into contact with it, and to provide a sufficient guiding range, without making the arc part too large to affect the overall structure of the locking head 200.

[0077] The arc-shaped limiting part 204 and the locking head 200 are manufactured using an integral molding process, ensuring a firm connection between the two. This allows them to withstand the force applied during drill pipe insertion and prevents the arc-shaped limiting part 204 and the locking head 200 from separating during use. The connection area has a smooth transition without obvious sharp edges or protrusions to prevent scratches on the drill pipe surface.

[0078] Drill rod approach stage: When the drill rod is raised to the vicinity of the second-level platform finger beam lock and is ready to be inserted into the finger beam, the drill rod first contacts the arc-shaped limiting part 204 of the lock head 200. Due to the shape of the arc-shaped limiting part 204, the drill rod will be naturally guided along the arc-shaped surface to the gap between the two lock heads 200.

[0079] Drill pipe entry stage: As the drill pipe continues to move, the arc-shaped limiting part 204 continuously guides the drill pipe, enabling it to accurately enter the limiting space between the two locking heads 200. During this process, the arc-shaped limiting part 204 effectively disperses the contact force between the drill pipe and the locking heads, reducing wear and damage caused by excessive local pressure. Simultaneously, the arc-shaped guiding effect makes the drill pipe entry angle more reasonable, reducing the possibility of locking head 200 displacement or drill pipe jamming due to angle deviation.

[0080] Drill rod positioning stage: After the drill rod successfully enters the limiting space, the arc-shaped limiting part 204 still plays a certain limiting role for the drill rod, preventing it from accidentally coming out during placement. At this time, the cooperation structure between the locking head 200 and the base 100, as well as the spring 300, work together to stably restrict the drill rod in the designated position.

[0081] If the second-layer platform finger beam lock is equipped with a spring element 300, when the drill pipe squeezes the lock head 200 to enter, the spring element 300 is compressed, providing a buffer for the drill pipe's entry. While the arc-shaped limiting part 204 guides the drill pipe smoothly into the ground, the buffering effect of the spring element 300 further ensures the smoothness of the drill pipe's entry process. After the drill pipe passes through, the spring element 300 resets, pushing the lock head 200 back to its initial limiting position. The arc-shaped limiting part 204 then again provides auxiliary limiting for the drill pipe, preventing it from shaking or coming out.

[0082] If the lock head 200 has a cylindrical guide portion 202 and the base 100 has a cylindrical groove 102, during the process of the arc-shaped limiting portion 204 guiding the drill rod in, the cylindrical guide portion 202 slides within the cylindrical groove 102, ensuring the stability of the lock head 200's movement. The arc-shaped limiting portion 204 works in conjunction with the cylindrical guide portion 202 and the cylindrical groove 102 to jointly ensure, from both guiding and stable movement aspects, that the drill rod can accurately and smoothly enter and be limited within the second-layer platform finger beam lock.

[0083] The guiding function of the arc-shaped limiting part 204 enables the drill pipe to quickly and accurately enter the limiting space between the lock heads 200. Compared with the case without the arc-shaped limiting part, the drill pipe placement time is shortened, which greatly improves the efficiency of drill pipe management in drilling operations.

[0084] The arc-shaped limiting part 204 effectively reduces wear and damage between the drill rod and the locking head 200 by dispersing contact force and optimizing the drill rod entry angle. During long-term use, the wear on the locking head 200 and the drill rod is reduced, extending the service life of the components and lowering equipment maintenance costs.

[0085] The arc-shaped limiting part 204 acts as an auxiliary limiting component after the drill pipe enters, working in conjunction with the main limiting structures of the lock head 200 and the base 100 to enhance the limiting stability of the drill pipe by the entire two-layer platform finger beam lock. This reduces the amplitude of drill pipe swaying during placement, minimizing potential safety hazards caused by drill pipe swaying and ensuring the safe conduct of drilling operations.

[0086] like Figures 2-3 As shown, a second-level platform is illustrated in another embodiment of this disclosure. This platform integrates the platform body 500, finger beams 600, and second-level platform finger beam locks to achieve efficient and stable management and positioning of the drill pipe. The platform body 500 serves as a basic support structure, providing an installation platform for the finger beams 600 and the second-level platform finger beam locks. The finger beams 600 are arranged in an orderly manner, with spaces between adjacent finger beams accommodating a row of drill pipes, enabling layered placement of the drill pipes. Second-level platform finger beam locks are installed on one or both sides of the finger beams 600 to further precisely position each drill pipe, preventing it from swaying or shifting at the second-level platform, ensuring safe and orderly drilling operations.

[0087] The drilling platform 500 is typically designed as a frame structure, constructed from steel beams or a high-strength alloy frame to ensure sufficient strength and stability to withstand the weight of the drill pipe and various forces generated during tripping in and out of the drilling rig. The shape and dimensions of the platform 500 are determined based on the actual space and operational requirements of the drilling platform, generally rectangular or square. Its length and width must accommodate the installation quantity and layout requirements of the finger beams 600, while the height must consider the operating space for personnel on the second-level platform and its coordination with other parts of the drilling equipment.

[0088] The platform 500 is securely installed in its corresponding position on the drilling platform via welding, bolting, or other suitable fixing methods. During installation, it is essential to ensure that the platform 500 is level to guarantee the stable placement of the finger beam 600 and drill pipe. Simultaneously, the connection between the platform 500 and the drilling platform must be reinforced, such as by adding reinforcing plates or supporting structures, to prevent loosening or deformation during long-term operation.

[0089] Several finger beams 600 are arranged sequentially on the platform 500 at certain intervals. The distance between two adjacent finger beams 600 is designed according to the diameter and arrangement of the drill rod, and is generally slightly larger than the total width when a row of drill rods is placed side by side, so that the drill rod can be easily inserted and removed. The finger beams 600 can be arranged in parallel, or they can be arranged at a certain angle according to the actual operation requirements to facilitate the rolling or sliding of the drill rod and improve the efficiency of drill rod retrieval.

[0090] One or both ends of the finger beam 600 are fixed to the platform 500 by welding, bolting, or slotting. The number and location of the connection points are determined according to the length of the finger beam 600 and the load-bearing requirements. For longer finger beams 600, connection points can be set at both ends and the middle to ensure that the finger beam 600 is firmly installed on the platform 500 and will not bend or shift when bearing drill pipe.

[0091] On one or both sides of the finger beam 600, several double-layered finger beam locks are arranged sequentially along the length of the finger beam. The spacing of the double-layered finger beam locks is determined according to the length and distribution requirements of the drill pipe, ensuring that the space between two adjacent double-layered finger beam locks can accurately accommodate a drill pipe and that the drill pipe is effectively limited after placement. For example, when setting double-layered finger beam locks on the finger beam 600, the spacing between adjacent locks can be evenly distributed according to the length of the drill pipe, ensuring that the drill pipe can be reliably limited at all positions on the finger beam.

[0092] Drill rod placement process: When the drill rod is lifted to the second-level platform, the operator places it in the space between adjacent finger beams 600. At this time, the drill rod first contacts the arc-shaped limiting part 204 of the second-level platform finger beam lock on the finger beam 600. Under the guidance of the arc-shaped limiting part 204, the drill rod smoothly enters the limiting space between the two adjacent second-level platform finger beam locks. The drill rod presses against the lock head 200, causing the lock head 200 to move against the elastic force of the spring member 300. After the drill rod passes through, the spring member 300 resets, driving the lock head 200 back to its initial position, firmly restricting the drill rod between the two lock heads 200.

[0093] Drill rod retrieval process: When a drill rod needs to be retrieved, the operator removes it from the limiting space of the second-level platform finger beam lock. During the retrieval process, the drill rod presses against the lock head 200 again, causing the lock head 200 to move. After the drill rod leaves the limiting space, the lock head 200 resets under the action of the spring 300, awaiting the placement of the next drill rod.

[0094] Limiting and Stabilizing: Throughout the process of placing the drill pipe on the second-level platform, the second-level platform finger beam lock, through its unique structural design, including the cooperation of the base 100, lock head 200, spring element 300, and limiting part, reliably limits the drill pipe. Even if vibration or shaking occurs during drilling operations, the drill pipe can be stably fixed on the finger beam 600, preventing displacement or falling, thus ensuring operational safety.

[0095] The rational layout of the 500-meter platform, the 600-meter finger beam, and the second-level platform finger beam lock allows drill pipes to be placed in an orderly, layered manner on the second-level platform, with each drill pipe having a corresponding placement and limiting position. Compared with the traditional second-level platform structure, the efficiency of drill pipe placement and retrieval is improved, allowing operators to find and operate the required drill pipes more quickly and accurately, reducing operation time and improving the overall efficiency of drilling operations.

[0096] The double-layer platform's finger-beam lock precisely limits the position of each drill pipe, enhancing its stability on the platform. During drilling operations, the drill pipe's sway is reduced compared to traditional structures, effectively decreasing the probability of accidents such as collisions and slippage caused by drill pipe sway, thus improving drilling safety and ensuring the safety of operators and equipment.

[0097] The arrangement of the finger beams 600, as well as the position and spacing of the finger beam locks on the second-level platform, can be adjusted according to the size of different drill pipe specifications and operational requirements. This flexibility allows the second-level platform to adapt to the management of various types of drill pipes. Compared with traditional second-level platforms, its adaptability to different drill pipe specifications is improved, reducing the need to replace the entire second-level platform structure due to changes in drill pipe specifications, thus reducing equipment costs and replacement time.

[0098] In some examples, such as Figures 2-3 As shown, the placement of the second-level finger beam lock on the top surface of the finger beam at 600mm is based on considerations for operations in confined spaces. In such spaces, traditional finger beam lock arrangements may be ineffective due to space constraints. Placing the finger beam lock on the top surface of the finger beam fully utilizes the relatively open space above it, avoiding interference with surrounding equipment or structures. This layout not only makes the installation and operation of the second-level finger beam lock more convenient but also effectively limits the drill pipe's movement within a limited space, ensuring smooth drilling operations in confined environments.

[0099] The top surface of the finger beam 600 is designed to accommodate the installation of a double-layer finger beam lock. A corresponding mounting plane or mounting groove is machined on the top surface of the finger beam 600 according to the dimensions of the base 100 of the double-layer finger beam lock. If a mounting plane is used, the surface flatness must be controlled to a high precision to ensure a tight fit between the base 100 and the top surface of the finger beam 600, ensuring the stability of the double-layer finger beam lock after installation. If a mounting groove is used, the groove's dimensions precisely match the base 100, allowing the base 100 to be tightly embedded in the mounting groove, preventing movement of the base 100 during operation.

[0100] When placing drill rods in confined spaces, the operator raises the drill rod above the finger beam 600, aligning it between the two adjacent second-level platform finger beam locks. If the lock head 200 has an arc-shaped limiting part 204, the drill rod will first contact the arc-shaped limiting part 204 and, guided by it, smoothly enter between the two lock heads 200. The drill rod presses against the lock head 200, causing it to move against the elastic force of the spring member 300. After the drill rod passes through, the spring member 300 resets, pulling the lock head 200 back to its initial position, thus confining the drill rod between the two lock heads 200.

[0101] When the drill rod needs to be retrieved, the operator lifts it upwards. The drill rod then presses against the locking head 200, causing it to move. After the drill rod leaves the limiting space, the locking head 200 returns to its original position under the action of the spring 300. Because the second-layer platform finger beam lock is located on the top surface of the finger beam 600, the operator has a relatively open operating space when retrieving the drill rod, making the operation more convenient and faster, and reducing the difficulty of operating in narrow spaces.

[0102] By placing the second-level platform finger beam lock on the top surface of finger beam 600, the previously relatively unused space above the finger beam is fully utilized, avoiding horizontal space competition with other equipment in a narrow space. Compared with the traditional finger beam lock arrangement, under the same narrow space conditions, this layout allows the second-level platform to accommodate more finger beams 600 and drill pipes, thus improving space utilization.

[0103] In confined spaces, operators can more easily access the double-layer finger beam lock from the top surface of the finger beam 600, eliminating the need to search for an operating position within a complex spatial structure. For example, when installing, debugging, or maintaining the double-layer finger beam lock, operators can work directly from the top surface of the finger beam 600, reducing operation time compared to traditional layouts, improving work efficiency, and also reducing the operational risks for operators in confined spaces.

[0104] The second-level platform finger beam lock is installed on the top surface of the finger beam at 600mm, effectively solving the problem of finger beam lock installation and use in narrow spaces. This allows the second-level platform to better adapt to various narrow space environments, such as small drilling platforms or downhole operation areas with limited space. Compared with traditional layouts, its applicability in narrow spaces is expanded, providing a reliable drill pipe limiting solution for drilling operations under special space conditions.

[0105] With ample operating space, operators can place and retrieve drill pipes more conveniently and efficiently, as well as operate the second-level platform finger beam lock. In the confined space, the time required for placing and retrieving drill pipes is reduced compared to traditional methods, decreasing overall drilling efficiency. Simultaneously, the ease of operation lowers the error rate caused by operator inconvenience, further ensuring operational safety.

[0106] By optimizing the spatial layout and making full use of the top surface space of the 600mm finger beam, the space utilization rate of the second-level platform in a confined space has been improved. This allows for the placement of more drill pipes within a limited space, meeting the needs for drill pipe storage and management in narrow environments and providing better support for the continuity of drilling operations.

[0107] In some examples, such as Figures 2-3 As shown, the second-level platform adopts a structure connecting the first platform body 501 and the second platform body 502, with a row of finger beams 600 on each, aiming to optimize space utilization and drill pipe storage management efficiency. The dual-platform design increases the number of finger beams 600, expanding the drill pipe storage capacity. At the same time, the two connected platforms can be flexibly laid out and functionally divided according to the actual needs of drilling operations, improving the adaptability of the second-level platform in different operating scenarios.

[0108] The first platform 501 and the second platform 502 can be connected by welding, bolting, or mortise and tenon joints. To ensure the integrity and stability of the two platforms after connection, a reinforcing structure is provided at the connection point. For example, reinforcing ribs are provided inside the platform connection, and connecting angle steel or connecting plates are provided on the outside to prevent relative displacement of the platforms during operation.

[0109] The finger beams 600 are arranged in a row at certain intervals on the first platform 501. One end of each finger beam 600 is fixed to the first platform 501 by welding, bolting, or slotting. The number and position of the connection points are determined according to the length of the finger beam 600 and the load-bearing requirements. The top surface of the finger beam 600 is provided with an installation structure that matches the base 100 of the second-level platform finger beam lock, facilitating the installation of the second-level platform finger beam lock. The arrangement of the finger beams 600 on the second platform 502 is similar to that on the first platform 501, but the spacing, length, or layout of the second-level platform finger beam locks can differ according to operational requirements.

[0110] Before drilling operations, operators place the drill pipes on the finger beams 600 of the first platform 501 and the second platform 502 according to the drill pipe specifications and usage sequence. The finger beams of the two platforms are locked to prevent shaking or displacement during storage. For example, drill pipes for regular drilling are placed on the first platform 501, while special or spare drill pipes are placed on the second platform 502.

[0111] When drill rods need to be retrieved during operation, the operator retrieves them from the corresponding finger beam 600 on the platform. First, the second-level platform finger beam lock is operated to move the lock head 200 to unlock. After the drill rod is retrieved, the second-level platform finger beam lock is reset by the action of the spring 300, ready for the next use.

[0112] Each of the two platforms is equipped with a 600mm finger beam. Compared with the single platform with two layers, the drill pipe storage capacity is greatly increased, which can meet the needs of more drill pipe storage, reduce the need for frequent drill pipe replenishment, and improve the continuity and efficiency of operation.

[0113] The differentiated design of the two-unit body finger beam 600 and the second-level platform finger beam lock allows the second-level platform to better adapt to the storage and management of drill pipes of different specifications. Compared with the traditional single-unit and fixed-layout second-level platform, it has significantly enhanced adaptability to different operating scenarios and can meet the requirements of diversified drilling operations.

[0114] The first platform 501 and the second platform 502 are connected by a reasonable connection and reinforcement structure, making the two-tiered platform structure more stable. When bearing the weight of the drill pipe and operational vibrations, the double-platform structure can better distribute stress. Compared with the single-platform structure, the overall stability is significantly improved, reducing safety risks and ensuring operational safety.
