Description

Technical Field

[0001] The utility model belongs to the technical field of oil drilling and production equipment, and particularly relates to a catwalk machine. Background Art

[0002] With the continuous progress of technology, oil drilling and production automation equipment at home and abroad, especially automation tools for drilling and production pipe strings, has been gradually popularized. Among them, power catwalk machines have been popularized at home and abroad. Configuring an automation tool system for drilling rigs has become a current development trend. As the core conveying equipment of the automation tool system in the technical field of oil and gas drilling and production equipment, the power catwalk machine is mainly applicable to safely and quickly convey the drilling and production pipe strings (such as drill pipes, drill collars, casing pipes, etc.) placed in the pipe rack or drill pipe box to the drill floor during the drilling process, and to convey the drilling and production pipe strings from the drill floor to the pipe rack or drill pipe box.

Detailed implementation manners

[0061] The following further describes the present utility model in detail with reference to specific embodiments, but the implementation manners of the present utility model are not limited thereto.

[0062] Embodiment 1

[0063] As Figure 1 , Figure 2 shown, a catwalk machine includes: a base 10, a lifting drive device 11, a support beam assembly 12, a lifting table 13, a horizontal drive device 14, a sliding table 20, and a pusher vehicle 30.

[0064] The lifting drive device 11 is located on one side of the support beam assembly 12. The fixed end of the lifting drive device 11 is hinged to the base 10, and the telescopic end of the lifting drive device 11 is hinged to one side of the support beam assembly 12. One end of the support beam assembly 12 is hinged to the base 10, and the other end of the support beam assembly 12 is hinged to the lifting platform 13. The lifting platform 13 is parallel to the base 10; the sliding platform 20 is slidably connected to the lifting platform 13; the fixed end of the horizontal drive device 14 is fixedly connected to the lifting platform 13, and the telescopic end of the horizontal drive device 14 is hinged to the sliding platform 20; the pusher cart 30 is slidably connected to the sliding platform 20. Among them, the support beam assembly 12 and the base 10 and the lifting platform 13 form a parallelogram structure. After the drill pipe from the low-position drill pipe box is grabbed by the pipe gripper and placed in the sliding platform 20 of the catwalk machine, the lifting drive device 11 extends to lift the support beam assembly 12 from the side, thereby raising the lifting platform 13 and the sliding platform 20, and horizontally lifting the drill pipe near the drill floor. The sliding platform 20 slides along the lifting platform 13 under the push of the horizontal drive device 14, so that the sliding platform 20 drives the drill pipe on it to move horizontally, thereby pushing the drill pipe backward to the drill floor, and the pusher cart 30 pushes the drill pipe further horizontally on the sliding platform 20 to the drill floor. When the catwalk machine is not working, the lifting drive device 11 retracts to tilt the support beam assembly 12, and the lifting platform 13 and the sliding platform 20 are lowered to a low position, reducing the overall center of gravity of the catwalk machine, saving the three-dimensional space of the drilling ship or the well site, and improving the safety and stability of transportation at the same time.

[0065] When the support beam assembly 12 is lifted to different positions, the sliding platform 20 is at different height positions, and the drill pipe maintains a horizontal state with a large lifting and moving range, so it can be applied to drilling rigs, workover rigs or drilling platforms with drill floors of different heights, and has strong adaptability and versatility.

[0066] Specifically, the support beam assembly 12 includes two mutually parallel support beam structures 121; one end of the support beam structure 121 is hinged to the base 10, and the other end of the support beam structure 121 is hinged to the lifting platform 13. The lifting drive device 11 is located outside the two support beam structures 121, and the telescopic end of the lifting drive device 11 is hinged to one support beam structure 121 close to the lifting drive device 11.

The piston rod of the lifting drive device 11 is hinged to the middle of the support beam structure 121 through a pin shaft, and the cylinder body of the telescopic hydraulic cylinder of the lifting drive device 11 is hinged to the left end of the base 10 through a pin shaft. The left side of the support beam structure 121 of the parallelogram structure is lifted by the telescopic hydraulic cylinder, and the support beam structure 121 rotates around the hinge pair pin shaft at its lower end. When the support beam structure 121 changes from the parallelogram structure to the rectangular structure, the lifting platform 13 of the catwalk machine supported on the support beam structure 121 is kept horizontal and drives the drill pipe on the sliding platform 20 thereon to rise from the low position to the high position, reaching the position flush with the drill floor surface.

[0069] Further, as Figure 3 , Figure 4 and Figure 5 shown, at least two pairs of guide blocks 131 are fixedly arranged on the lifting platform 13. A pair of guide blocks 131 includes two guide blocks 131. The paired guide blocks 131 are respectively located on the two tracks 132 of the lifting platform 13. Among them, the lifting platform 13 includes two tracks 132 extending in the horizontal direction. The guide block 131 includes: a lower guide slider 133 and an upper pressing plate slider 134. The lower guide slider 133 and the upper pressing plate slider 134 are oppositely arranged on the upper and lower sides of the track 132, and the connecting seat 22 of the sliding platform 20 is arranged between the lower guide slider 133 and the upper pressing plate slider 134, and the connecting seat 22 is in sliding contact with the lower guide slider 133 and the upper pressing plate slider 134.

One end of the cylinder body of the horizontal drive device 14 is bolted to the lifting platform 13 through a fixing plate, and the outer end of the piston rod of the horizontal drive device 14 is hinged to the bottom of the sliding platform 20 through a pin shaft. Eight lower guide sliders 133 are arranged at the lower edge of the track 132 of the lifting platform 13, and eight upper pressing plate sliders 134 corresponding to the lower guide sliders 133 are arranged at the upper edge. Under the guidance and limitation of the lower guide sliders 133 and the upper pressing plate sliders 134, the sliding platform 20 slides along the upper and lower planes of the lower guide sliders 133 and the upper pressing plate sliders 134 of the lifting platform 13 under the push of the horizontal drive device 14, so that the sliding platform 20 drives the drill pipe thereon to move horizontally, thereby pushing the drill pipe backward towards the drill floor surface.

[0071] Preferably, the lifting platform 13 is connected to the rectangular pipe connecting seat 22 of the sliding platform 20 through a planar pair formed by the upper plane of the lower guiding slider 133 and the lower plane of the upper pressing plate slider 134 thereon. The lower guiding slider 133 and the upper pressing plate slider 134 are connected to the lower guiding slider 133 seat and the upper pressing plate slider 134 guiding seat on the lifting platform 13 respectively through bolts to form a bolt pair connection. The cylinder block of the horizontal driving device 14 is installed on the oil cylinder mounting seat at the bottom of the lifting platform 13 through a pressing plate and bolts.

[0073] The connecting seat 22 is hinged to the telescopic end of the horizontal driving device 14 through a pin shaft. The V-shaped chute 21 is horizontally and fixedly arranged on the connecting seat 22, and racks 35 extending along the long axis of the V-shaped chute 21 are respectively arranged on the outer edges of the two side walls of the V-shaped chute 21. The long axes of the V-shaped chute 21 and the connecting seat 22 extend along the lifting platform 13 and are parallel to the lifting platform 13. The rack 35 is located above the upper pressing plate slider 134.

[0074] The V-shaped guide rail shoe is fixedly connected to the bottom of the vehicle body 31, and the V-shaped guide rail shoe is in sliding contact with the inner wall of the V-shaped chute 21. The inner surface of the V-shaped chute 21 and the outer surface of the V-shaped guide rail shoe form a planar pair contact. The driving motor 32 is fixedly connected to the vehicle body 31 through a bolt pair of a bolt and a nut, the output end of the driving motor 32 is in transmission connection with the gear. The gear meshes with the rack 35. The rear limit wheel assembly 33 is arranged at one end of the connecting seat 22 close to the lifting driving device 11, and the rear limit wheel assembly 33 is located between the outer side wall of the connecting seat 22 and the lifting platform 13.

[0075] In this embodiment, the rack 35 is connected to the V-shaped chute 21 through a thread pair of a bolt. The gear is connected to the cylindrical surface of the output shaft of the driving motor 32 through a cylindrical pair, the gear and the rack 35 form a gear pair meshing, and the driving motor 32 is connected to the vehicle body 31 through bolts and a motor seat to form a bolt pair connection. The driving motor 32 drives the vehicle body 31 to move, and the V-shaped guide rail shoe of the pushing cart 30 is in planar contact with the V-shaped chute 21 of the sliding platform 20, so that the pushing cart 30 slides horizontally along the long axis of the V-shaped chute 21. Thus, after the lifting platform 13 rises to the drill floor, the pushing cart 30 can push the drill pipe from the front far away from the drill floor to the drill floor, facilitating the drill pipe receiving device on the drill floor to grab the drill pipe.

[0076] Preferably, the rear limiting wheel assembly 33 includes two limiting wheels and two support plates for mounting the two limiting wheels. The support plates are fixed to the connecting seat 22. The limiting wheels of the rear limiting wheel assembly 33 are mounted on the support plates. The limiting wheels are in contact with the outer sidewall of the connecting seat 22 and the inner sidewall of the track 132, and roll when the connecting seat 22 slides.

[0078] In this embodiment, the pressing rod 39 is used to press the drill pipe tightly in the V-shaped chute 21 to prevent the drill pipe from slipping out and ensure the safety of the equipment and personnel during operation. The piston rod of the telescopic hydraulic cylinder 37 extends and retracts diagonally upward to the left away from the drill pipe receiving device. The piston rod and the pressing rod 39 are located on both sides of the installation plate 36. When the piston rod extends, it drives the connecting arm 38 to rotate downward around the hinge point of the connecting arm 38 and the installation plate 36, so that the pressing rod 39 moves downward and can press on the drill pipe. On the contrary, when the piston rod contracts, the pressing rod 39 moves upward away from the drill pipe to facilitate grasping and moving the drill pipe.

[0079] Preferably, the pressing rod 39 is fixedly connected to the connecting arm 38 through a pin shaft. The connecting arm 38 is hinged to the piston rod of the telescopic hydraulic cylinder 37 through a pin shaft. The connecting arm 38 is hinged to the installation plate 36 through a pin shaft.

The other end of the swing arm 41 extends in a direction away from the V-shaped chute 21. The two parallel arms of the swing arm 41 are hinged to the roller 42 through a roller shaft. The piston rod, the connecting structure, and the swing arm form a crank and connecting rod mechanism. The swing arm 41 is driven by the swing hydraulic cylinder 40 to swing up and down, so as to lift and guide the drill pipe pushed to the right (front) of the V-shaped chute 21 by the pusher cart 30 obliquely upward for easy transportation above the drill floor, facilitating the grasping of the drill pipe by the tools on the floor.
