Description

Technical Field

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

[0002] With the deepening development of coalbed methane and oil extraction, and the maturity and widespread application of automated drilling technology, coalbed methane extraction has placed higher demands on drilling and production equipment. Among these, the tubing conveying device is an auxiliary device used to transport drill pipes during drilling operations, enabling efficient transfer of drill pipes between the drilling platform and the ground.

[0003] In related technologies, drill string conveying devices typically consist of a boom, lifting arm, and ramp assembly. The lifting arm enables the boom to move up and down, thus conveying the drill string between different heights. However, because the boom needs to be lifted as a whole, these conveying devices require significant drive power and a robust load-bearing structure. Consequently, the boom and lifting arm must withstand substantial loads, resulting in a complex overall structure, increased size, bulk, and time-consuming assembly and disassembly, as well as inconvenient transportation. Summary of the Invention

[0004] In view of this, the present invention provides a tubular column conveying device to solve the problem that the cloud beam needs to be lifted as a whole, resulting in a large overall size and inconvenience in disassembly, assembly and transportation.

[0005] In a first aspect, the present invention provides a tubing conveying device suitable for conveying tubing, the tubing conveying device comprising: frame; The cloud beam is connected to the frame and is set at an angle A with the frame; the cloud beam is provided with guide grooves, which are set along the extension direction of the cloud beam. The sliding shoe mechanism is adapted to move along the extension direction of the frame. The sliding shoe mechanism is adapted to abut the first end of the tube column and drive the second end of the tube column to slide along the guide groove. The support mechanism is movably connected to the rack and has a first state of being concealed within the rack and a second state of extending from the rack and abutting the column; when the support mechanism is in the second state, it is adapted to support the middle region of the column.

[0006] Beneficial Effects: The pipe column conveying device provided in the embodiments of the present invention, by setting a support mechanism, effectively supports the middle area of ​​the pipe column during the conveying process, reduces the bending deformation of the pipe column caused by its own weight, and improves the stability and safety of the pipe column conveying; at the same time, the support mechanism can be retracted into the frame when not in operation, reducing the overall structural volume and facilitating transportation and installation; combined with the slipper mechanism to push the pipe column along the guide groove, it achieves stable and efficient conveying of the pipe column, eliminating the need for overall lifting of the cloud beam, significantly reducing the driving power and structural load-bearing requirements, effectively reducing the size and weight of the equipment, with a compact overall structure, reasonable stress distribution, significantly reducing the requirements for the installation foundation, making disassembly and assembly more convenient, transportation easier, improving the convenience of on-site installation and operational adaptability, and meeting the needs of rapid deployment in complex operating environments.

[0007] In one alternative embodiment, the support mechanism includes: a main rod, one end of which is hinged to the frame via a flipping shaft; and a drive rod, one end of which is hinged to the middle region of the main rod, and the other end of which is hinged to the frame. The extension and retraction of the drive rod is adapted to drive the main rod to rotate around the flipping axis, so that the support mechanism switches between the first state and the second state.

[0008] Beneficial effects: By controlling the drive rod, the support mechanism can be adaptively switched under different working conditions, which not only meets the need for convenient equipment deployment and retraction, but also improves the stability and reliability of the tubular column delivery.

[0009] In one alternative embodiment, a roller is provided at the other end of the main rod, the roller being adapted to roll along the outer circumferential surface of the tube column.

[0010] Beneficial effects: The rollers further reduce the frictional resistance between the main rod and the tube column, making the support mechanism more flexible and smooth during the support process. When the tube column slides along the guide groove, the rollers can roll synchronously with the outer circumference of the tube column, avoiding obstruction or wear caused by relative stillness, and effectively protecting the integrity of the tube column surface.

[0011] In one alternative embodiment, there are two main rods, and each of the two main rods is provided with a roller at the other end. Both rollers are constructed in a conical shape, and the small ends of the conical shapes are arranged opposite each other.

[0012] Beneficial effects: The small ends of the two conical rollers form a V-shaped clamping structure, which automatically centers itself when in contact with the outer circumference of the tubing, effectively preventing lateral displacement of the tubing during transport. Simultaneously, during inclined transport, the rollers can adapt to changes in the tubing's position in real time, providing continuous and stable dynamic support to prevent swaying or displacement.

[0013] In one alternative embodiment, the tubular conveying device further includes a lifting rod, one end of which is hinged to the frame and the other end of which is connected to the cloud beam via a support base.

[0014] Beneficial effects: The lifting boom provides fixed support for the cloud beam. To accommodate different drilling platform heights, the tilt angle of the cloud beam can be adjusted by replacing lifting booms of varying lengths, thereby changing the installation height of the cloud beam. One end of the lifting boom is hinged to the frame, and the other end is hinged to the cloud beam via a support base. This allows the cloud beam to rotate around its hinge point with the frame after the lifting boom is disassembled, facilitating the overall folding, storage, and transportation of the device. During transportation, the cloud beam can be directly flipped onto the frame, enabling transport as a whole vehicle.

[0015] In one alternative embodiment, the frame is provided with a groove along its extension direction, and the sliding shoe mechanism is adapted to reciprocate along the groove.

[0016] Beneficial effect: By setting a groove on the frame, the sliding shoe mechanism is given precise guidance, ensuring that it moves stably along a predetermined trajectory.

[0017] In one alternative implementation, the slipper mechanism includes: Support for the skateboard body; Guide wheels are provided on the support shoe body and are adapted to guide the support shoe body to move along the extension direction of the frame; A guide shoe is provided on the support shoe body, and the guide shoe is adapted to abut the first end of the pipe post.

[0018] In one alternative embodiment, the slipper mechanism further includes a chain connected to the supporting slipper body, the chain being driven to move so as to cause the supporting slipper body to reciprocate relative to the frame.

[0019] In one alternative embodiment, the tubular delivery device further includes: The translation drive mechanism is installed on the cloud beam. The translation drive mechanism is adapted to drive the pipe column to slide along the guide groove after the first end of the pipe column enters the guide groove of the cloud beam.

[0020] Beneficial effects: When the sliding shoe mechanism moves to one end of the frame near the cloud beam, it pushes the tube column to the predetermined position. The tube column and the cloud beam are completely in contact. The translation drive mechanism set on the cloud beam is activated. The clamping assembly is driven to move horizontally along the guide groove through the hydraulic push rod or servo motor, and the feed stroke of the tube column is precisely controlled.

[0021] In one alternative implementation, the main rod is constructed as a telescopic rod.

[0022] Beneficial effects: By designing the main rod as a telescopic structure, the length can be automatically adjusted according to the actual position of the tube and the conveying requirements, further improving the adaptability and flexibility of the support mechanism.

[0029] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0030] With the deepening development of coalbed methane and oil extraction, and the maturity and widespread application of automated drilling technology, coalbed methane extraction has placed higher demands on drilling and production equipment. Among these, the tubing conveying device is an auxiliary device used to transport drill pipes during drilling operations, enabling efficient transfer of drill pipes between the drilling platform and the ground.

[0031] In related technologies, drill string conveying devices typically have structures such as a boom, lifting arm, and ramp assembly. One end of the lifting arm is hinged to the boom, and the other end is connected to the ramp assembly. The lifting arm is driven by a hydraulic cylinder, which in turn drives the boom to rise and fall, thus completing the conveying of drill rods between different heights. Although it has the advantages of high efficiency in vertical drill rod throwing and the ability to throw multiple drill rods simultaneously, in practical applications, the boom needs to be lifted as a whole, resulting in a large drive power and load-bearing structure. The equipment is bulky and requires a high degree of stability in the installation foundation. Installation at the drilling rig site is laborious and time-consuming, and disassembly and assembly are inconvenient, as is transportation.

[0032] The following is combined Figures 1 to 6 The following describes embodiments of the present invention.

[0033] According to an embodiment of the present invention, in one aspect, a tubing conveying device is provided, suitable for conveying tubing 3, the tubing conveying device comprising: Rack 5; The cloud beam 2 is connected to the frame 5 and is set at an angle A with the frame 5; the cloud beam 2 is provided with a guide groove 21, which is set along the extension direction of the cloud beam 2; The sliding shoe mechanism 7 is adapted to move along the extension direction of the frame 5. The sliding shoe mechanism 7 is adapted to abut the first end of the tube column 3 and drive the second end of the tube column 3 to slide along the guide groove 21. Support mechanism 4 is movably connected to frame 5. Support mechanism 4 has a first state of being hidden inside frame 5 and a second state of extending out of frame 5 and abutting against column 3. When support mechanism 4 is in the second state, support mechanism 4 is adapted to support the middle region of column 3.

[0034] The pipe column conveying device provided in the embodiments of the present invention, by setting a support mechanism 4, effectively supports the middle area of ​​the pipe column 3 during the conveying process, reduces the bending deformation of the pipe column 3 due to its own weight, and improves the stability and safety of the pipe column 3 conveying. At the same time, the support mechanism 4 can be retracted into the frame 5 when not in operation, reducing the overall structural volume and facilitating transportation and installation. Combined with the slipper mechanism 7 pushing the pipe column 3 along the guide groove 21, the pipe column 3 is conveyed smoothly and efficiently without the need for overall lifting of the cloud beam, which greatly reduces the driving power and structural load-bearing requirements, effectively reduces the size and weight of the equipment, and has a compact overall structure with reasonable stress distribution. It significantly reduces the requirements for the installation foundation, makes disassembly and assembly more convenient, and transportation easier, improving the convenience of on-site installation and operational adaptability, and meeting the needs of rapid deployment in complex operating environments.

[0035] The support mechanism 4 in this embodiment can increase the support for the middle part of the column 3, effectively share the bending moment caused by the weight of the column 3, and reduce the deflection deformation of the column during transportation. Compared with traditional column transportation devices, it does not include the lifting arm and ramp assembly, which can eliminate the complex drive mechanism and heavy load-bearing structure required for the overall lifting of the cloud beam, thus making the overall structure simpler, significantly reducing equipment manufacturing costs, and reducing subsequent maintenance costs. It is easy to assemble and disassemble, and facilitates modular transportation.

[0036] In this embodiment, the support mechanism 4 has a first state hidden inside the frame 5 and a second state extending from the frame 5 and abutting the pipe column 3. Under the action of the drive component, the switching between the first state and the second state is realized, thereby realizing dynamic support for the pipe column 3. During the pipe column transportation process, the support state can be automatically adjusted according to the actual working conditions to improve the continuity of operation.

[0037] The support mechanism 4 is movably connected to the frame 5, and can be extended or retracted by sliding, rotating or folding to ensure flexible switching under different working conditions.

[0038] The drive assembly can employ hydraulic or electric actuator structures, etc.

[0039] The cloud beam 2 is connected to the frame 5 and is set at an angle A with the frame 5. The angle A is an obtuse angle, which can be selected between 120° and 150°. By arranging it at an angle, the tube column 3 slides along with the tube during the conveying process to form a natural upward trend, which further reduces the pushing resistance and improves the conveying efficiency.

[0040] The cloud beam 2 is provided with a guide groove 21, which is set along the extension direction of the cloud beam 2. The guide groove 21 is used to accommodate the second end of the tube column 3 and guide it to slide along a predetermined trajectory to ensure the directional stability of the tube column 3 during the conveying process. The cross-section of the guide groove 21 can be U-shaped or V-shaped, which facilitates the effective limiting and guidance of the tube column 3 and prevents it from shifting laterally or getting stuck during the conveying process.

[0041] The sliding shoe mechanism 7 is adapted to reciprocate along the extension direction of the frame 5. The sliding shoe mechanism 7 is adapted to abut the first end of the tube column 3 and drive the second end of the tube column 3 to slide along the guide groove 21, realizing continuous pushing of the tube column. This allows the tube column 3 to slide along the guide groove 21 of the cloud beam 2 and gradually rise to the target position, achieving efficient and stable conveying operations. Through the synergistic effect of the sliding shoe mechanism 7 and the guide groove 21, the frictional resistance between the tube column 3 and the cloud beam 2 is effectively reduced, improving the smoothness of pushing. Simultaneously, the inclined cloud beam 2 allows the tube column to rise naturally during movement, avoiding the energy loss caused by frequent lifting and lowering of traditional equipment.

[0042] In some embodiments, combined with Figure 3 As shown, the support mechanism 4 includes: a main rod 43, one end of which is hinged to the frame 5 via a flip shaft 42; and a drive rod 44, one end of which is hinged to the middle area of ​​the main rod 43, and the other end of which is hinged to the frame 5. The extension and retraction of the drive rod 44 is adapted to drive the main rod 43 to rotate around the flipping shaft 42, so that the support mechanism 4 switches between the first state and the second state.

[0043] As a specific implementation of the movable connection between the support mechanism 4 and the frame 5, the support mechanism 4 in this embodiment is hinged to the frame 5 through the flip shaft 42. When the drive rod 44 extends or retracts, it pushes the main rod 43 to rotate around the flip shaft 42, thereby realizing the switching of the support mechanism 4 between the first state and the second state.

[0044] When the support mechanism 4 is in the first state, the main rod 43 is close to the frame 5. By opening a corresponding receiving space on the frame 5, the main rod 43 can be stored inside the frame 5, thereby avoiding affecting the reciprocating movement of the slipper mechanism 7, ensuring that the tube column pushing process is smooth and unobstructed, and not occupying external space, thus improving the overall compactness of the equipment. When the support mechanism 4 is in the second state, the main rod 43 flips out from inside the frame 5, providing effective support for the middle of the tube column 3, and enhancing its overall stability during the inclined conveying process.

[0045] By controlling the drive rod 44, the support mechanism 4 can be adaptively switched under different working conditions, which not only meets the need for convenient equipment deployment and retraction, but also improves the stability and reliability of the tubular column delivery.

[0046] In this embodiment, the drive rod 44 can be a hydraulic or electric push rod.

[0047] In some embodiments, a roller 41 is provided at the other end of the main rod 43, and the roller 41 is adapted to roll along the outer circumferential surface of the column 3.

[0048] The roller 41 further reduces the frictional resistance between the main rod 43 and the column 3, making the support mechanism 4 more flexible and smooth during the support process. When the column 3 slides along the guide groove 21, the roller 41 can roll synchronously with the outer circumference of the column 3, avoiding obstruction or wear caused by relative stillness, and effectively protecting the integrity of the column surface.

[0049] Furthermore, the roller 41 can be made of nylon, which has good wear resistance and can maintain a low coefficient of friction even when in long-term contact with the metal column, reducing noise and wear during operation. At the same time, nylon has a certain degree of elastic deformation capability, which can buffer the minor vibrations of the column 3 during transportation, further improving the support stability of the support mechanism.

[0050] In some embodiments, there are two main rods 43, and each of the two main rods 43 is provided with a roller 41 at the other end. Both rollers 41 are constructed in a conical shape, and the small ends of the conical shapes are arranged opposite each other.

[0051] Combination Figure 1 As shown, there are two main rods 43, which are symmetrically arranged along the axis of the tube column 3. The two main rods 43 can be synchronously driven by the same drive rod 44 to achieve linkage flipping, or they can be independently controlled by independent drive rods 44 to adapt to the working conditions of different tube column diameters or tilt angles.

[0052] In this embodiment, the small ends of the two conical rollers 41 form a V-shaped clamping structure, which can automatically center when in contact with the outer circumferential surface of the tube, effectively preventing lateral displacement of the tube during transportation. At the same time, during inclined transportation, the rollers 41 can adapt to changes in the position of the tube in real time, providing continuous and stable dynamic support to prevent it from shaking or shifting.

[0053] As a variation, in some other embodiments, the main body rod 43 is constructed as a telescopic rod.

[0054] By designing the main rod 43 as a telescopic structure, its length can be automatically adjusted according to the actual position of the tubular column 3 and the conveying requirements, further enhancing the adaptability and flexibility of the support mechanism 4. The telescopic action can be achieved by hydraulic, pneumatic, or electric drive, and with the help of sensors to provide real-time feedback on the tubular column position, it ensures uniform and stable support force. It is especially suitable for conveying tubular columns of different lengths under varying working conditions, effectively enhancing the intelligence and adaptability of the equipment.

[0055] The following combination Figures 2 to 5 This document describes in detail the specific workflow of the tubing conveying device in this embodiment when conveying tubing.

[0056] Initial drilling stage: First, combine Figure 2 As shown, the support mechanism 4 is in the first state, the main rod 43 is stored inside the frame 5, and the sliding shoe mechanism 7 moves, driving the tube column 3 to move smoothly along the guide groove 21. At this time, the angle θ between the tube column 3 and the plane of the frame 5 is small, the center of gravity of the tube column is low, the stability of the conveying process is high, and no additional support is required.

[0057] Support for the diamond delivery phase: combined with Figure 3 As shown, as the conveying process progresses, the included angle θ gradually increases, and the distance L between the sliding shoe mechanism 7 and the tail end of the frame 5 gradually increases. The center of gravity of the tube column 3 shifts upward. At this time, the drive rod 44 is activated, pushing the main rod 43 to rotate outward around the flipping shaft 42, causing the conical rollers 41 at both ends to extend synchronously and fit against the outer circumference of the tube column, forming a V-shaped clamping structure to achieve dynamic centering and lateral constraint. At this time, the support mechanism 4 and the sliding shoe mechanism 7 work together. The support mechanism 4 provides lateral constraint and dynamic support, while the sliding shoe mechanism 7 maintains axial propulsion force, ensuring that the tube column 3 maintains a stable trajectory even under large-angle conveying.

[0058] Continuous drilling phase: combined Figure 4 As shown, as the tube column 3 continues to convey, the included angle θ further increases. At this time, the sliding shoe mechanism 7 gradually approaches the hinge position of the support mechanism 4. In order to avoid the support mechanism 4 interfering with the movement of the sliding shoe mechanism 7, the drive rod 44 controls the main body rod 43 to flip in the opposite direction, so that the roller 41 gradually withdraws from contact with the tube column 3. The included angle β between the main body rod 43 and the plane where the frame 5 is located gradually decreases, so that the support mechanism 4 returns to the first state. At the same time, the sliding shoe mechanism 7 continues to advance along the frame 5 to ensure that the conveying action is continuous and unobstructed.

[0059] Termination of drilling phase: combined with Figure 5 As shown, the sliding shoe mechanism 7 moves to one end of the frame 5 near the cloud beam 2, pushes the column 3 to the predetermined position, the column 3 and the cloud beam 2 are completely in contact, the included angle θ reaches the maximum value, and the column 3 is pushed into full position.

[0060] In some embodiments, the tubular conveying device further includes a lifting rod 1, one end of which is hinged to the frame 5, and the other end is connected to the cloud beam 2 via a support base 11.

[0061] In this embodiment, the lifting rod 1 serves as a fixed support for the cloud beam 2. Since the cloud beam 2 does not need to be lifted as a whole, the lifting rod 1 only needs to maintain stable support during the pipeline transportation process. Its structure is relatively simple. For example, a rigid rod of fixed length can be used, which is hinged to the frame and support seat through a pin to ensure that the cloud beam is positioned stably and reliably during transportation.

[0062] Meanwhile, in order to adapt to the height of different drilling platforms, the tilt angle of the cloud beam 2 can be adjusted by replacing the lifting rod 1 with different lengths, thereby changing the installation height of the cloud beam 2.

[0063] Furthermore, one end of the lifting rod 1 is hinged to the frame 5, and the other end is hinged to the cloud beam 2 via the support base 11. This allows the cloud beam 2 to rotate around its hinge point with the frame 5 after the lifting rod 1 is disassembled, facilitating the overall folding, storage, and transportation of the device. During transportation, the cloud beam 2 can be directly flipped onto the frame 5, enabling full-vehicle transport. The hinged structure, combined with the quick-release pin design, significantly improves disassembly and assembly efficiency, adapting to the needs of frequent site relocation operations.

[0064] As a variation, an adjusting screw or hydraulic telescopic device can be set as the lifting rod 1, and the tilt angle and installation height of the cloud beam 2 can be dynamically adjusted by changing its length to adapt to different working conditions.

[0065] In some embodiments, the frame 5 is provided with a groove 51 along the extending direction, and the sliding shoe mechanism 7 is adapted to reciprocate along the groove 51.

[0066] By setting a groove 51 on the frame 5, the sliding shoe mechanism 7 is provided with precise guidance, ensuring that it moves stably along a predetermined trajectory.

[0067] Specifically, the frame 5 is constructed as a welded steel structure, and the height of the base can be adjusted according to different drilling platforms. A V-shaped plate is welded in the middle of the welded steel structure to form a groove 51, which is used to guide the sliding shoe mechanism 7.

[0068] In some embodiments, combined with Figure 6 As shown, the slipper mechanism 7 includes: Support for the slipper body 75; A guide wheel 71 is provided on the support shoe body 75, and the guide wheel 71 is adapted to guide the support shoe body 75 to move along the extension direction of the frame 5; A guide shoe 73 is disposed on the support shoe body 75, and the guide shoe 73 is adapted to abut the first end of the pipe post 3.

[0069] Guide wheels 71 are symmetrically installed on both sides of the supporting slipper body 75. The frame 5 is provided with a guide rail structure that matches the guide wheels 71 to ensure that the slipper mechanism runs smoothly and does not deviate during movement.

[0070] The guide shoe 73 is located at the front end of the support shoe body 75, and contacts the first end of the tube column 3 to limit its movement, effectively preventing the tube column from moving axially during the conveying process.

[0071] Optionally, the inner side of the guide shoe 73 is inlaid with a wear-resistant rubber pad, which protects the surface of the tubing from damage and enhances friction to improve conveying stability.

[0072] The slipper mechanism 7 also includes a connecting plate 76, which is fixed to the supporting slipper body 75. The connecting plate 76 and the guide slipper 73 are arranged at an angle. Preferably, the angle between the connecting plate 76 and the guide slipper 73 is 90°, so that they together form a stable support for the first end of the column 3.

[0073] In some embodiments, the slipper mechanism 7 further includes a chain 72 connected to the support slipper body 75, the chain 72 being driven to move so as to cause the support slipper body 75 to reciprocate relative to the frame 5.

[0074] The slipper mechanism 7 also includes a drive motor, which is connected to a sprocket. The sprocket meshes with the chain 72 to drive the slipper mechanism 7 to move automatically back and forth along the frame 5.

[0075] Chain 72 can be a ring chain with the ends connected. It drives the sprocket to rotate through the drive motor, so as to achieve continuous and stable reciprocating motion. The stroke is equal to the length of the entire frame 5.

[0076] In some embodiments, the tubular delivery device further includes: Translation drive mechanism 6 is provided on cloud beam 2. Translation drive mechanism 6 is adapted to drive the tube column 3 to slide along the guide groove 21 after the first end of the tube column 3 enters the guide groove 21 of cloud beam 2.

[0077] When the sliding shoe mechanism 7 moves to one end of the frame 5 near the cloud beam 2, pushing the tube column 3 to the predetermined position, the tube column 3 and the cloud beam 2 are fully engaged. The translation drive mechanism 6, mounted on the cloud beam 2, is then activated, driving the clamping assembly to move horizontally along the guide groove 21 via a hydraulic push rod or servo motor, precisely controlling the feed stroke of the tube column 3. Optionally, the clamping assembly has built-in sensors to monitor the position and attitude of the tube column in real time, ensuring its stable insertion into the positioning position of the cloud beam 2.

[0078] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and all such modifications and variations fall within the scope defined by the present invention.
