Description

Technical Field

[0001] The utility model relates to the technical field of oil and natural gas drilling, in particular to a two-layer platform emergency pipe grabbing and laying machine. Background Art

[0002] At present, in oil and gas drilling systems, the second-level platform is an important work area for pipe discharge and processing. Under normal working conditions, the main pipe loader undertakes the key task of arranging and transferring drill pipes, casing and other pipes in order, which plays a vital role in ensuring the efficient and orderly development of drilling work.

[0003] To ensure the stability of the pipe, an intermediate finger beam is typically placed in the corresponding area below the second-level platform finger beam. In drilling systems with both a second-level platform finger beam and an intermediate finger beam, if the pipe racker fails, the drill string is typically removed from the second-level platform finger beam using the second-level platform's hydraulic winch and manual assistance, then connected to the traveling crane system for pipe handling. However, the intermediate finger beam can easily get stuck in the drill string, preventing it from being released smoothly. This prolongs the time it takes to detach from the finger beam, impacting operational efficiency. Furthermore, manual assistance requires working at height, posing a safety hazard.

[0004] Therefore, there is an urgent need for a two-layer emergency pipe grabbing and laying machine with high safety and operating efficiency. Utility Model Content

DETAILED DESCRIPTION

[0034] To better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0035] like Figure 1-Figure 5As shown, the specific embodiment of the utility model provides a second-layer platform emergency pipe grabbing and laying machine, including a main beam 1, a sub-beam 2, a first moving assembly 3, a first rotary drive 4, a second moving assembly 5, a second rotary drive 6, a telescopic column assembly 7 and a clamp assembly 8; the main beam 1 is installed on the derrick, and is located on the rear side of the second-layer platform main pipe laying machine on the derrick, the first moving assembly 3 is movably installed on the main beam 1, and the sub-beam 2 is installed on the bottom of the first moving assembly 3 through the first rotary drive 4; the second moving assembly 5 is movably installed on the sub-beam 2, and the telescopic column assembly 7 is installed on the bottom of the second moving assembly 5 through the second rotary drive 6; the clamp assembly 8 is installed at the bottom end of the telescopic column assembly 7.

[0036] Specifically, the main beam 1 is installed on the rear side of the main pipe laying machine on the second-level platform on the derrick, and the structural design of the main and auxiliary beams 2 is adopted, which can solve the problem of adding an emergency pipe grabbing and laying machine in the limited space of the second-level platform without affecting the normal operation of the main pipe laying machine. In daily drilling operations, the main pipe laying machine can grab, transfer and discharge pipes in an orderly manner according to the established process, and the emergency pipe grabbing and laying machine on the second-level platform is in a standby state parallel to the auxiliary beam 2 and the main beam 1 due to its rear installation and reasonable structural layout. It will not cause any obstruction or interference to the main pipe laying machine in space and during operation, ensuring the efficient and smooth implementation of the entire drilling pipe processing process under normal working conditions. When the main pipe laying machine fails due to various unforeseen reasons (such as equipment failure, sudden mechanical damage, etc.), the emergency pipe grabbing and laying machine on the second-level platform can be quickly started and put into use, seamlessly connecting the functions of the main pipe laying machine to carry out pipe grabbing and laying operations. Due to the coordinated and collaborative design of its main beam 1, auxiliary beam 2, first mobile assembly 3, first rotary drive 4, second mobile assembly 5, second rotary drive 6, telescopic column assembly 7, and lifting clamp assembly 8, it can quickly and accurately locate the pipes to be handled, achieve efficient pipe grabbing operations, and orderly transfer the pipes to the handover point and hand them over to the traveling lifting system. This effectively avoids long-term drilling operation stoppages caused by failures of the main pipe laying machine, ensures that drilling work can continue in emergency situations, and greatly reduces the time cost and economic losses caused by sudden equipment problems to the entire oil and gas drilling project. Compared with existing technologies, both operational efficiency and safety have been greatly improved.

[0037] Furthermore, if Figure 1 、 Figure 6 and Figure 7As shown, the main beam 1 is provided with a first track 11 extending along its length. The first movable assembly 3 includes a first vehicle body 31, a first drive assembly, and first travel rollers 32. The first vehicle body 31 is movably supported on the first track 11 by the first travel rollers 32. The first rotary drive 4 is mounted on the bottom of the first vehicle body 31, and the sub-beam 2 is mounted on the first rotary drive 4. The first drive assembly is mounted on the first vehicle body 31 and is capable of driving the first trolley to move along the first track 11. Specifically, the first track 11 extending along the length of the main beam 1 provides a clear and stable guide for the first movable assembly 3, ensuring that the movement path of the first vehicle body 31 on the main beam 1 is precise and predictable.

[0038] Furthermore, as shown in the figure, in this embodiment, the main beam 1 is also provided with a first rack 12 extending along its length. The first drive assembly includes a first driver 33 and a first gear 34. The first driver 33 is connected to the first rack 12 via the first gear 34 to drive the first gear 34 to rotate. The rotation of the first gear 34, via the first rack 12, drives the first trolley 31 along the first track 11. The first trolley 31 is movably supported on the first track 11 by first running rollers 32. This rolling support reduces friction during movement, allowing the first trolley 31 to move easily and smoothly along the first track 11. This reduces energy loss and ensures that the device can quickly respond to pipe handling tasks and quickly reach the target area, improving the timeliness of emergency operations and avoiding delays in drilling operations due to slow movement. The first rack 12 extending along the length of the main beam 1 cooperates with the first gear 34 in the first drive assembly to form a rack and pinion transmission. This transmission method offers the advantages of high transmission precision, strong load-bearing capacity, and considerable transmission efficiency. The power output by the first driver 33 is transmitted through the meshing of the first gear 34 and the first rack 12, precisely converting it into linear motion for the first trolley along the first track 11, achieving high-precision positioning of the first trolley. In complex, precision-critical working environments like the second-level oil and gas drilling platform, each pipe handling operation requires precise positioning. The rack and pinion drive ensures that the first trolley can be moved to the target position with the required accuracy, effectively avoiding problems such as difficulty in pipe grasping or subsequent pipe handling errors caused by movement errors. This provides reliable power transmission for the smooth execution of the entire emergency pipe grasping and pipe handling operation, improving overall operational performance and reliability.

[0039] Furthermore, if Figure 7As shown, multiple first anti-fall members 35 are provided on the edge of the first vehicle body 31; the first vehicle body 31 is slidably connected to the first track 11 via the multiple first anti-fall members 35. In the event of an emergency (such as a failure of the first running roller 32), the first vehicle body 31 can be prevented from accidentally falling off the track, thereby ensuring the safety and stability of the entire operation process.

[0040] Furthermore, if Figure 1 、 Figure 8 and Figure 9 As shown, the subbeam 2 has a second track 21 extending along its length. The second moving assembly 5 includes a second vehicle body 51, a second drive assembly, and second travel rollers 52. The second vehicle body 51 is supported on the second track 21 via the second travel rollers 52. A second rotary drive 6 is mounted on the bottom of the second vehicle body 51, and a telescopic column assembly 7 is mounted on the second rotary drive 6. The second drive assembly is mounted on the second vehicle body 51 and is capable of driving the second vehicle body 51 along the second track 21. Specifically, the subbeam 2 has a second rack 22 extending along its length. The second drive assembly includes a second driver 53 and a second gear 54. The second driver 53 is connected to the second rack 22 via the second gear 54, driving the second gear 54 to rotate. The rotation of the second gear 54 drives the second vehicle body along the second track 21 via the second rack 22. The second track 21 extending along the length of the subbeam 2 provides a dedicated travel path for the second moving assembly 5. Together with the first track 11 on the main beam 1, it forms a two-dimensional horizontal movement system for the device.

[0041] Furthermore, if Figure 8 and Figure 9 As shown, there are two second rails 21, one on each side of the subbeam 2. The second car body 51 includes a base plate 511 and two side plates 512 fixed to the base plate 511. Second rollers are disposed on the inner sides of the side plates 512. The second rollers on the two side plates 512 are supported on the two second rails 21, providing more stable and reliable support and guidance for the second car body 51. The second drive 53 and the second rotary drive 6 are mounted on the base plate 511. The second car body 51 is provided with a plurality of second anti-drop components 55, specifically on the two side plates 512. The second car body 51 is slidably connected to the second rails 21 via the second anti-drop components 55, providing further safety and enhancing safety and stability during operation.

[0042] Furthermore, if Figure 10As shown, the telescopic column assembly 7 includes an outer column 71, an inner column 72, and a telescopic actuator 73. The outer column 71 is sleeved onto the inner column 72, and the tong assembly 8 is mounted at the bottom of the inner column 72. The ends of the telescopic actuator 73 are connected to the outer column 71 and the inner column 72 to drive the inner column 72 to move the tong assembly 8 up and down. Specifically, the inner column 72 has guide grooves 74 on both sides, and the outer column 71 is provided with composite rollers 75 connected to the guide grooves 74. The guide grooves 74 on both sides of the inner column 72 cooperate with the composite rollers 75 on the outer column 71, which are connected to the guide grooves 74, to provide precise guidance and limit the lifting and lowering movement of the inner column 72.

[0043] The use of the two-layer emergency pipe grabbing and rafting machine provided by the present invention is as follows: after the main pipe rafting machine fails, the first rotary drive 4 drives the sub-beam 2 to rotate in the horizontal plane to be perpendicular to the main beam 1, and then the second rotary drive 6 drives the telescopic column assembly 7 to drive the clamp assembly 8 to rotate to the target angle. Then, according to the storage position of the pipe, the first moving assembly 3 drives the sub-beam 2 to move, and the second moving assembly 5 drives the telescopic column assembly 7 to move. The clamp assembly 8 is extended and lowered by the telescopic column assembly 7, so that the clamp assembly 8 reaches the storage position and clamps the target pipe. Then, the telescopic column assembly 7 is retracted and the clamp assembly 8 is used to lift the target pipe out of the storage position. After that, the first moving assembly 3 and the second moving assembly 5 cooperate to transport the target pipe to the handover position. Finally, the clamp assembly 8 is used to hand over the target pipe to the traveling crane system to complete the pipe grabbing operation.
