Description

Technical Field

[0001] The present invention relates to the technical field of oil drilling and well repair, in particular to an anti-swing system for traveling crane equipment. Background Art

[0002] During drilling and well repair operations in oil and gas fields, the traveling block, as the core load-bearing and execution component of the traveling crane equipment, is the key equipment for achieving high-precision operations such as pipe string lifting and accurate placement of downhole tools. Its dynamic stability directly determines the safety factor and construction efficiency of downhole operations, and is the core element to ensure the continuous and controllable operation process.

[0003] Compared with conventional drilling rigs, the operating conditions of workover rigs present more complex challenges: First, workover operation areas are mostly distributed in old oil fields with a long development history or in urban areas. There is a non-uniform wind shear field formed by a large number of high-rise buildings in the operating environment. At the same time, the densely arranged well site equipment will generate irregular turbulence. Such environmental factors can easily cause the traveling block to produce non-steady-state oscillation during hovering or movement; second, in actual operations, when encountering extreme working conditions such as sudden gusts of wind of level 6 or above, or sudden obstruction at the wellhead, the lateral swing of the traveling block can easily exceed the safety threshold of ±10cm, resulting in out-of-range oscillation, which can easily cause rigid collisions between key equipment such as elevators and blowout preventers, causing structural damage to the equipment; the wire rope can jump out of the pulley groove, causing the load-bearing system to fail; in extreme cases, it can even cause major safety accidents such as pipe string falling, directly threatening the life safety of on-site workers and the integrity of equipment.

[0041] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0042] like Figure 1 As shown, an embodiment of the present invention provides an anti-swing system for a traveling hoisting device, wherein the traveling hoisting device includes a derrick, a traveling carriage a3 and a lifting ring a4, and the lifting ring a4 is movably connected to the large hook of the traveling carriage a3. In this embodiment, the derrick adopts a segmented design, which is divided into an upper section a1 of the derrick and a lower section a2 of the derrick to adapt to the space requirements of the transportation scene. When the equipment is transported, the upper section a1 of the derrick can be slid along the longitudinal direction and stacked in the lower section a2 of the derrick. Through the roller device provided between the two, it can not only realize the smooth sliding of the upper section a1 of the derrick in the lower section a2 of the derrick, but also play a reliable limiting role in the sliding process, avoiding offset or jamming during the stacking process. It should be noted that the specific stacking principle of the upper section a1 of the derrick and the lower section a2 of the derrick belongs to the existing technology in this field and will not be elaborated here.

[0043] like Figure 2 As shown, the anti-swing system includes a guide rail 1, a guide assembly 2, a damping arm assembly 3, a swing drive assembly 4, a hinge seat 5 and a control device. The guide rail 1 is set on one side of the derrick in the vertical direction. The guide rail 1 includes an upper guide rail 11 and a lower guide rail 12 spliced ​​together. The top side of the upper guide rail 11 is hinged to the derrick. The guide assembly 2 is fixedly set on one side wall of the traveling block a3 and cooperates with the upper guide rail 11 and the lower guide rail 12. Figure 6 As shown, the hinge seat 5 is provided on the derrick, and one side of the top end of the upper guide rail 11 is hinged to the derrick through the hinge seat 5. The control device is electrically connected to the damping arm assembly 3 and the swing drive assembly 4 respectively.

[0044] By setting the guide rail 1 hinged to the derrick in the vertical direction and the top end, cooperating with the guide assembly 2 fixed with the traveling block a3 and guided with the guide rail 1, the traveling block a3 can be effectively guided to move along the guide rail 1, fundamentally limiting the lateral displacement of the traveling block a3 relative to the guide rail 1, and greatly reducing the non-steady-state rolling of the traveling block a3 caused by non-uniform wind shear field, equipment turbulence and the like during hovering or movement.

[0045] The damping arm assembly 3 is arranged between the bottom end of the lower guide rail 12 and the derrick, and is used to provide damping force for the oscillation of the bottom end of the guide rail 1 relative to the derrick, so as to buffer the impact force generated by the movement of the traveling block a3 or in extreme working conditions, further improve the dynamic stability of the traveling block a3, and avoid the swing amplitude exceeding the safety threshold. And avoid connecting the guide rail 1 and the derrick in a rigid reinforcing manner, when the traveling block a3 encounters gusts, wellhead sudden jamming and other extreme conditions, the huge impact force causes the connection part to break due to stress concentration, thereby ensuring the safety and efficiency of the operation.

[0046] At the same time, the swing driving assembly 4 is fixed relative to the traveling block a3, and the swing driving assembly 4 is used to drive the swing of the lifting ring a4 to reset the elevator a5 at the far end of the lifting ring a4. As shown in Figure 4 and Figure 5 When the impact is too large, the guide rail 1 deviates from the original position, causing the lifting ring a4 connected by the traveling block a3 to deviate from the working position, and the position of the lifting ring a4 is adjusted by the swing driving assembly 4 to reset the elevator a5 at the far end of the lifting ring a4, thereby ensuring the stability of the work of the elevator a5.

[0047] As shown in Figure 3 The damping arm assembly 3 includes a connecting base 31, a damping rod 32 and a hinged frame 33, the connecting base 31 is arranged on the derrick, one end of the damping rod 32 is connected with the connecting base 31, and the other end of the damping rod 32 is hinged with the bottom end of the lower guide rail 12. Among them, the damping rod 32 can be a TMD damping rod, a hydraulic damping rod, a magnetic damping rod and the like.

[0048] The hinged frame 33 is arranged above the damping rod 32, the hinged frame 33 includes a hinged first hinged arm 331 and a second hinged arm 332, the other end of the first hinged arm 331 is hinged with the derrick, and the other end of the second hinged arm 332 is hinged with the lower guide rail 12. By setting the hinged frame 33, the left and right direction deviation of the guide rail 1 relative to the derrick can be avoided, the guide rail 1 is guided to move along the extension direction of the damping rod 32, thereby enhancing the support and buffering effect of the damping arm assembly 3 on the guide rail 1, and improving the stability of the whole device under complex working conditions.

[0049] As shown in Figure 2As shown, the swing driving assembly 4 comprises a telescopic driving member 41, a rigid shift fork 42, a connecting rod 43, a first connecting seat 44 and a second connecting seat 45. The fixed end of the telescopic driving member 41 is connected with the guide assembly 2, the driving end of the telescopic driving member 41 is hingedly connected with one side of the rigid shift fork 42, the first hinged joint of the rigid shift fork 42 is hingedly connected with the trolley a3, the second hinged joint of the rigid shift fork 42 is hingedly connected with the first end of the connecting rod 43, and the second end of the connecting rod 43 is hingedly connected with the rod part of the lifting ring a4. The first hinged joint of the rigid shift fork 42 is located below the driving end of the telescopic driving member 41 and close to the trolley a3, and the telescopic driving member 41 can drive the rigid shift fork 42 to rotate around the first hinged joint to drive the connecting rod 43 to swing the lifting clamp a5 at the far end of the lifting ring a4, so as to reset the lifting clamp a5 to the original working state. It should be noted that the swing driving assembly 4 can also be used to drive the lifting clamp a5 to swing to the catwalk and other positions so as to facilitate the lifting clamp a5 to clamp the pipe.

[0050] In order to facilitate the hinged connection, the first connecting seat 44 is sleeved on the trolley a3, the first hinged joint of the rigid shift fork 42 is hingedly connected with the first connecting seat 44, and the second connecting seat 45 is fixedly arranged on the rod part of the lifting ring a4, and the second end of the connecting rod 43 is hingedly connected with the second connecting seat 45.

[0051] In order to realize the accurate regulation and control of the position of the lifting clamp, a position sensor is arranged in the damping rod 32, and the sensor is used to collect the offset amount between the lower guide rail 12 and the derrick caused by external forces such as wind load and vibration.

[0052] The control device is connected with the position sensor and the power source of the telescopic driving member 41 respectively, the position sensor feeds back the offset amount information between the damping rod 32 and the lower guide rail 12 to the control device, the control device controls the telescopic action of the telescopic driving member 41 according to the offset amount information, and finally realizes the original working position keeping of the lifting clamp a5 under external disturbance.

[0053] As shown in Figure 4 When the telescopic driving member 41 adopts the hydraulic driving mode, when subjected to the left wind force, the lower guide rail 12 moves left relative to the derrick, the position sensor collects the left offset amount and feeds back to the control device. The control device immediately issues an instruction to control the power source of the telescopic driving member 41 to reduce the hydraulic oil output, and under the action of the hydraulic oil, the telescopic arm of the telescopic driving member 41 is retracted by a certain displacement, driving the lifting ring a4 to move away from the derrick, so as to restore the lifting clamp a5 to the original working state.

[0054] As shown in Figure 5As shown, when subjected to the right wind force, the position sensor collects that the lower guide rail 12 moves right relative to the derrick, the control device responds immediately, instructs the power source of the telescopic drive 41 to increase the hydraulic oil output, drives the telescopic arm of the telescopic drive 41 to extend a certain displacement, promotes the lifting ring a4 to move to the direction close to the derrick, and further ensures the clamp a5 to reset to the original working state.

[0055] It should be noted that the specific telescopic displacement of the telescopic arm needs to be determined according to the actual working condition by mechanical modeling and engineering calculation in combination with the arrangement form of the connecting rod structure in the swing driving assembly, the length of the rod body and other parameters. Since the calculation principle belongs to the prior art, it will not be expanded here.

[0056] In the embodiment, in order to facilitate the disassembly and assembly of the device, the guide rail 1 is a detachable segmented structure. As shown in Figure 1 The upper guide rail 11 is arranged on the upper section a1 of the derrick, and the lower guide rail 12 is detachably arranged on the lower section a2 of the derrick.

[0057] In the working state, the upper guide rail 11 and the lower guide rail 12 are arranged in parallel and partially overlap in the vertical direction to form an overlapping section, and the overlapping section is detachably connected by a connecting piece, wherein the connecting piece is a quick-release latch. Compared with the long guide rail 1 integrally formed in the prior art, the segmented structure of the upper guide rail 11 and the lower guide rail 12 solves the problem of complicated disassembly and low efficiency caused by the long guide rail 1 during frequent moving and transporting of the device, and significantly improves the convenience of disassembly, assembly, moving and transporting of the device. The upper guide rail 11 and the lower guide rail 12 are locked or unlocked through the detachable connection of the overlapping section. In the working state, the overlapping section is locked by the connecting piece to ensure the overall stability of the guide rail 12 device in the working state. When the derrick is folded, the connecting piece is removed, the upper guide rail 11 and the lower guide rail 12 are unlocked, the upper section a1 of the derrick drives the upper guide rail 11 to move downward, so that the upper guide rail 11 can slide along the outer side of the lower guide rail 12 to realize the substantial coincidence in the length direction, which greatly reduces the space occupation in the non-working state and is convenient for storage and transportation.

[0058] The guide assembly 2 can guide with the upper guide rail 11 and the lower guide rail 12. When the guide assembly 2 is located on the upper guide rail 11, the guide assembly 2 guides with the upper guide rail 11. When the guide assembly 2 is located on the lower guide rail 12, the guide assembly 2 guides with the lower guide rail 12. When the guide assembly 2 is located on the overlapping section, the guide assembly 2 guides with the upper guide rail 11 and the lower guide rail 12 at the same time.

[0059] As shown in Figure 10As shown, when the device needs to be transported, the upper section a1 of the derrick slides into the lower section a2 of the derrick, the connecting piece is disassembled, so that the upper rail 11 and the lower rail 12 can move relatively, the upper section a1 of the derrick drives the upper rail 11 to slide downward along the outer side of the lower rail 12 to gradually increase the length of the overlapping section, and the upper rail 11 is stacked on the outer side of the lower rail 12. The guide assembly 2 is guided and matched with the upper and lower rails 12, which ensures that the traveling block a3 always moves stably along the guide rail during lifting, effectively avoids the swing and swing of the elevator a5 in the no-load stage, guarantees the operation accuracy and safety, and is compatible with the structural design of the sectional guide rail, without affecting the continuity of the guide function.

[0060] As shown in Figure 1 , when the upper rail 11 and the lower rail 12 are in a working state, in order to ensure the structural strength and stability of the connection between the two, the length of the overlapping section is not less than one sixth of the total length of the upper rail 11, and by ensuring the overlapping contact area of the upper rail 11 and the lower rail 12 in the connected state, the deformation or swing of the guide rail device when bearing the load of the traveling block a3 due to the too short overlapping length is avoided, and the reliability of the guiding process is further improved.

[0061] As shown in Figure 7 and Figure 8 , in order to match the upper rail 11 and the lower rail 12 respectively, the guide assembly 2 includes a sliding seat 21 and two guide units 22. The guide assembly 2 is matched with the upper rail 11 and the lower rail 12 respectively through the two guide units 22, realizes the guiding connection of the traveling block a3 and the sectional guide rail, ensures that the traveling block a3 can still stably transition at the junction of the upper and lower rails 12, and avoids interruption or jamming in guiding. When the guide assembly 2 is located on the upper rail 11 only, one guide unit 22 of the guide assembly 2 is guided and matched with the upper rail 11, when the guide assembly 2 is located on the lower rail 12 only, the other guide unit 22 of the guide assembly 2 is guided and matched with the lower rail 12, and when the guide assembly 2 is located on the overlapping section, the two guide units 22 of the guide assembly 2 are guided and matched with the upper rail 11 and the lower rail 12 respectively.

[0062] As shown in Figure 7As shown, the horizontal section of the upper guide rail 11 and the lower guide rail 12 is all I-shaped, and the two sides of the upper guide rail 11 and the lower guide rail 12 are respectively formed with sliding grooves, and the guide unit 22 includes two sliding block groups 221, and the two sliding block groups 221 of one guide unit 22 are respectively arranged in one-to-one correspondence with the two sliding grooves of the upper guide rail 11 and are in sliding connection, and the two sliding block groups 221 of the other guide unit 22 are respectively arranged in one-to-one correspondence with the two sliding grooves of the lower guide rail 12 and are in sliding connection. That is, the guide unit 22 is in double-side sliding cooperation with the upper guide rail 11 and the lower guide rail 12, which greatly improves the stability and anti-tilting ability of the guide, effectively limits the shaking of the traveling car a3 in the horizontal direction, and further guarantees the operation accuracy. Among them, the sliding block group 221 can be at least one sliding block arranged along the longitudinal direction. The sliding connection mode of the sliding block and the sliding groove is simple in structure, moderate in frictional resistance, suitable for high-frequency lifting operation of the traveling car a3, easy to replace after wear, and high in practicability.

[0063] As shown in the figure, Figure 8 The guide unit 22 can include two roller groups 222, and the two roller groups 222 of one guide unit 22 are respectively arranged in one-to-one correspondence with the two sliding grooves of the upper guide rail 11 and are in rolling connection, and the two roller groups 222 of the other guide unit 22 are respectively arranged in one-to-one correspondence with the two sliding grooves of the lower guide rail 12 and are in rolling connection. The rollers are used instead of the sliding blocks to cooperate with the sliding grooves of the I-shaped guide rail, the rolling friction is used instead of the sliding friction, the friction in the guiding process is significantly reduced, the wear of the guide rail and the guide assembly 2 is reduced, the service life of the equipment is prolonged, the lifting operation of the traveling car a3 is smoother, and the energy consumption is reduced. The cooperation of the double-side rollers and the sliding grooves can also ensure the stability of the guide, and the rotating characteristics of the rollers are more adaptable to the small size error of the sliding grooves, which reduces the processing accuracy requirement and saves the manufacturing cost.

[0064] As shown in the figure, Figure 9 The inside of the overlapping section of the upper guide rail 11 is provided with at least one group of sliding shoes 6, and the sliding shoes 6 are in sliding connection with the outer side wall of the lower guide rail 12. In the process of folding the derrick, the upper guide rail 11 slides along the outer side of the lower guide rail 12 and overlaps, which plays an auxiliary guiding and supporting role, avoids scratching or deviation between the upper guide rail 11 and the lower guide rail 12, ensures the smoothness of the overlapping process, protects the surface of the guide rail from being damaged, and improves the durability of the equipment.
