Description

Technical Field

[0001] The present invention relates to the technical field of hanger seal ring installation, and more particularly to a sealing component set device and method for a hanger. Background Art

[0002] A hanger is a key component of a wellhead device in oil and gas development, mainly used for hanging a tubing string and sealing the annular space between the tubing and the casing. The installation of the sealing component of the hanger is the core barrier to ensure wellhead safety, and its performance directly affects the integrity of the oil and gas well. At wellheads with relatively low pressure and mild conditions, an elastic sealing method is usually adopted. There are two sets of sealing components used in elastic sealing, and the two sets of sealing components are respectively installed at different diameters on the hanger body. Each set of sealing components includes two elastic sealing rings with a specified spacing to ensure the sealing effect.

[0003] Currently, the method of sleeving the sealing ring onto the hanger body mainly uses manual sleeving. During the sleeving process, the sealing ring will experience friction and torsion when being pushed into the sealing groove on the hanger body. Moreover, since each set of sealing components includes two sealing rings, one sealing ring will enter the installation position of the other sealing ring during the installation process. The staff needs to push out this sealing ring and continue to push it to the specified installation position. The operation is relatively cumbersome and the manual labor intensity during the sleeving process is relatively large, making it difficult to meet the requirements of large-scale production. Summary of the Invention

Detailed implementation manners

[0019] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. Usually, the components of the embodiments of the present invention described and illustrated herein can be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0021] Embodiment The following is with reference to Figures 1-9 As shown in the figure, a sealing component sleeving device for a hanger is further described in combination with specific embodiments. In this embodiment, the hanger includes a hanger body 100 and two annular groove groups 10 formed on the hanger body 100. Both of the two annular groove groups 10 include a first sealing groove 11 and a second sealing groove 12.

[0022] In this embodiment, the two annular groove groups 10 are respectively located at different diameters of the hanger body 100. The axial spacing between the first sealing groove 11 and the second sealing groove 12 of the two annular groove groups 10 is the same, and the first sealing groove 11 is located above the second sealing groove 12. And in other embodiments, the number of annular groove groups 10 on the hanger body 100 and the number of sealing grooves of the annular groove groups 10 can be increased or decreased correspondingly according to the actual situation.

[0023] The sealing component sleeving device includes a workbench 20, a lifting platform 30, a turntable 40 and a first installation component 50. Among them, the workbench 20 is sequentially provided with a feeding station 21, a first sleeving station 22 and a second sleeving station 23 along the circumferential direction. The lifting platform 30 is liftably arranged on the workbench 20, and its lifting height is equal to the axial spacing between the first sealing groove 11 and the second sealing groove 12 in the same annular groove group 10 of the hanger body 100. The turntable 40 is rotatably arranged on the lifting platform 30, and at least one carrier seat 41 for carrying the hanger body 100 is arranged on its surface. In this embodiment, the number of carrier seats 41 is three to correspond to the feeding station 21, the first sleeving station 22 and the second sleeving station 23.

[0024] The first installation component 50 is arranged at the first sleeving station 22 and is used for sequentially sleeving sealing rings 521 into the first sealing groove 11 and the second sealing groove 12 of one of the annular groove groups 10. The first installation component 50 includes an installation frame 51, a blanking frame 52 arranged on the installation frame 51, and a grasping unit 53 that is liftably arranged below the blanking frame 52. The blanking frame 52 includes a storage cavity with an opening at the top and the bottom. A number of sealing rings 521 are stacked in the storage cavity. The grasping unit 53 is used to individually grasp the sealing rings 521 at the bottom of the blanking frame 52 and sequentially sleeve them into the first sealing groove 11 and the second sealing groove 12.

[0025] Through the above design, the grasping unit 53 can effectively grasp the sealing rings 521 one by one and accurately sleeve them into the specified sealing grooves, thus avoiding the possible friction and torsion problems in the manual sleeving process. After the first sealing ring 521 is sleeved, the design of the lifting platform 30 enables the height to be automatically adjusted when grasping and sleeving the second sealing ring 521, ensuring that the sealing ring 521 can be accurately sleeved into the second sealing groove 12.

[0026] Furthermore, the grasping unit 53 includes a lifting plate 531, a set of elastic pieces, and a connecting rope 533. Among them, the lifting plate 531 is vertically movable on the mounting bracket 51. A through hole 5311 for the suspension body 100 to pass through is formed on the surface of the lifting plate 531, so that the lifting plate 531 can descend to the two annular groove groups 10 of the suspension body 100. The set of elastic pieces includes a plurality of elastic pieces 532 evenly distributed on the periphery of the through hole 5311. A plurality of rotating grooves 5312 for cooperating with the elastic pieces 532 are correspondingly formed on the lifting plate 531. The middle part of the elastic piece 532 is hinged in the rotating groove 5312. The elastic piece 532 includes a grasping part 5321 extending into the through hole 5311 and an abutting part 5322 for elastically abutting against the inner wall of the rotating groove 5312. The abutting part 5322 elastically abuts against the inner wall of the rotating groove 5312 through an elastic piece 5323. One end of the connecting rope 533 passes through a plurality of rotating grooves 5312 in sequence to connect the abutting parts 5322 of a plurality of elastic pieces 532, and the other end is connected to a driving electric cylinder 534. The driving electric cylinder 534 is configured to control the rotation angle of the abutting part 5322 by releasing or winding the connecting rope 533, so as to drive the grasping parts 5321 of the elastic pieces 532 to rotate towards each other or away from each other.

[0027] By hinging the middle part of the elastic piece 532 in the rotating groove 5312 (through a rotating shaft), when the driving electric cylinder 534 releases or winds the connecting rope 533, it drives the abutting parts 5322 of a plurality of elastic pieces 532 to rotate, thereby driving the grasping parts 5321 of a plurality of elastic pieces 532 to rotate towards each other or away from each other at the same time. Specifically, when the driving electric cylinder 534 winds the connecting rope 533, it drives the abutting part 5322 to abut against the inner wall of the rotating groove 5312, so that the grasping part 5321 moves away from each other. At this time, the grasping parts 5321 of the elastic pieces 532 expand outwards, thereby grasping the sealing ring 521; when the driving electric cylinder 534 releases the connecting rope 533, the abutting part 5322 automatically rebounds due to elastically abutting against the inner wall of the rotating groove 5312, driving the grasping part 5321 to move towards each other. At this time, the grasping parts 5321 of the elastic pieces 532 contract inwards, thereby loosening the sealing ring 521.

[0028] Furthermore, the inner diameter of the bottom of the blanking frame 52 is smaller than that of its top, and a guiding and avoiding groove 522 adapted to the elastic piece 532 is provided at the bottom of the blanking frame 52.

[0029] By setting the inner diameter of the bottom of the blanking rack 52 to be smaller than that of its top, after the grasping unit 53 grasps the sealing ring 521 at the bottom of the blanking rack 52, the sealing ring 521 inside the blanking rack 52 will not fall off. At the same time, through the setting of the guiding avoidance groove 522, the grasping part 5321 of the elastic piece 532 can smoothly enter the inside of the blanking rack 52 and be inserted into the gap between the two sealing rings 521 at the bottom of the blanking rack 52, so as to be able to grasp the sealing ring 521 located at the bottom of the blanking rack 52.

[0030] Furthermore, the grasping unit 53 further includes an expansion airbag 535 provided at the grasping end of the elastic piece 532, which can expand or contract; when the expansion airbag 535 expands, the grasping part 5321 of the elastic piece 532 grasps the sealing ring 521 and drives the sealing ring 521 to descend to one of the ring groove groups 10 of the hanger body 100; when the expansion airbag 535 contracts, the grasping part 5321 of the elastic piece 532 releases the sealing ring 521, so that the sealing ring 521 can be automatically sleeved in the sealing groove.

[0031] By adding the expansion airbag 535 to the grasping part 5321 of the grasping unit 53, when the expansion airbag 535 expands, the grasping part 5321 of the elastic piece 532 can firmly grasp the sealing ring 521 and drive it to descend to the target position; when the expansion airbag 535 contracts, the grasping part 5321 of the elastic piece 532 can release the sealing ring 521, so that it can be automatically sleeved in the sealing groove.

[0032] The expansion airbag 535 can be controlled to expand and contract by the charging and discharging of gas, so as to realize the control of the grasping part 5321 of the elastic piece 532. Specifically, a gas source 536 can be connected inside the expansion airbag 535, and the expansion and contraction are realized by controlling the switch of the gas source 536. When the expansion airbag 535 expands, it will push the grasping part 5321 of the elastic piece 532 to expand outwards, so as to grasp the sealing ring 521; when contracting, the grasping part 5321 of the elastic piece 532 will contract inwards, so as to release the sealing ring 521. Thus, the automatic sleeving of the sealing ring 521 can be effectively realized.

[0033] Further, a vertical pole 31 is provided on the lifting platform 30. A first switch 311 and a second switch 312, which are electrically connected to the driving electric cylinder 534, are provided on the pole 31. The first switch 311 is located above the second switch 312, and the first switch 311 and the second switch 312 are trigger-type travel switches. When the lifting plate 531 moves to abut against and trigger the first switch 311, the driving electric cylinder 534 winds up the connecting rope 533, causing the grasping portions 5321 of the plurality of elastic pieces 532 to move away from each other, thereby grasping the sealing ring 521. When the lifting plate 531 moves to abut against and trigger the second switch 312, the driving electric cylinder 534 operates and releases the connecting rope 533, causing the grasping portions 5321 of the plurality of elastic pieces 532 to rotate towards each other, thereby releasing the sealing ring 521.

[0034] By providing the pole 31 on the lifting platform 30 and installing the first switch 311 and the second switch 312 on the pole 31, precise control of the driving electric cylinder 534 can be achieved, thereby controlling the movement of the grasping portions 5321 of the elastic pieces 532.

[0035] In addition, it should be noted that in this embodiment, the first switch 311 and the second switch 312 are also electrically connected to the air source 536. When the driving electric cylinder 534 operates and drives the grasping portions 5321 of the elastic pieces 532 to expand or contract, the air source 536 synchronously controls the expansion or contraction of the expansion airbag 535, thereby realizing the stable grasping and releasing of the sealing ring 521.

[0036] Further, the first mounting assembly 50 further includes a lifting cylinder 54 for driving the lifting plate 531 to vertically lift and lower. The piston rod of the lifting cylinder 54 is vertically downward, and the piston rod of the lifting cylinder 54 is fixedly connected to the lifting plate 531.

[0037] By providing the lifting cylinder 54, the automatic lifting and lowering of the lifting plate 531 is realized, avoiding the cumbersome and error-prone manual operation, and improving the efficiency and accuracy of the sleeving of the sealing ring 521.

[0038] Further, the sealing component sleeving device further includes a first driving component 60 for driving the lifting platform 30 to vertically lift and lower relative to the workbench 20; the first driving component 60 includes two sliding strips 61 symmetrically arranged on both sides of the lifting platform 30 and a double-acting cylinder 62 for driving the two sliding strips 61 to move synchronously towards or away from each other. The sliding strip 61 includes an inclined surface 611 for abutting against the lifting platform 30. The double-acting cylinder 62 includes a guide rail and two sliders 621 slidably arranged on the guide rail. Corresponding to the sliding strip 61 on the workbench 20, a chute 24 is provided. After the two sliders 621 pass through the chute 24, they are respectively fixedly connected to the two sliding strips 61.

[0039] Specifically, by driving the two sliders 621 of the bi-directional cylinder 62 to move towards or away from each other, the two sliding bars 61 are driven to move, thereby changing the height of the lifting platform 30, that is, realizing the lifting of the lifting platform 30.

[0040] Furthermore, the seal assembly sleeving device further includes a second driving assembly 70 for driving the turntable 40 to rotate, so that the carrier seat 41 on the turntable 40 sequentially passes through the feeding station 21, the first sleeving station 22, and the second sleeving station 23. The second driving assembly 70 includes a driving gear 71 rotatably disposed on the lifting platform 30 and a driving motor 72 for driving the driving gear 71 to rotate. The output shaft of the driving motor 72 is fixedly connected to the driving gear 71, and an external gear ring 42 meshing with the driving gear 71 is provided on the outer peripheral side of the turntable 40.

[0041] By providing the driving motor 72 and the driving gear 71, the automatic driving of the turntable 40 is realized, so that the hanger body 100 can sequentially pass through the feeding station 21, the first sleeving station 22, and the second sleeving station 23 for the sleeving operation of the sealing ring 521.

[0042] Furthermore, the seal assembly sleeving device further includes a second mounting assembly 80. The structure of the second mounting assembly 80 is the same as that of the first mounting assembly 50 and is disposed on the second sleeving station 23. The second mounting assembly 80 is used to sequentially sleeve the sealing rings 521 into the first sealing groove 11 and the second sealing groove 12 of another ring groove group 10 of the hanger body 100.

[0043] In this embodiment, the structures of the first mounting assembly 50 and the second mounting assembly 80 are the same, and the difference lies in the different diameters of the through holes 5311 of the main lifting plate 531. Since the two ring groove groups 10 on the hanger body 100 are correspondingly disposed at different diameters of the hanger body 100, the sizes of the through holes 5311 of the lifting plates 531 of the first mounting assembly 50 and the second mounting assembly 80 are different, so that the lifting plates 531 of the first mounting assembly 50 and the second mounting assembly 80 can respectively descend to the positions corresponding to the two ring groove groups 10, thereby realizing the sleeving of the sealing rings 521 for the two ring groove groups 10.

[0044] By providing the second mounting assembly 80, the seal assembly sleeving device provided in this application can simultaneously perform the sleeving operation of the sealing rings 521 on the two ring groove groups 10 of the hanger body 100, improving the working efficiency and reducing the complexity and labor intensity of manual operation.

[0045] In addition, this embodiment further provides a sleeving method for applying the seal assembly sleeving device for a hanger, including the following steps: 101. Feed the hanger body 100 at the feeding station 21 so that the hanger body 100 is placed on the carrier seat 41 corresponding to the feeding station 21. In this embodiment, the hanger body 100 can be placed on the carrier seat 41 at the feeding station 21 by manual feeding or mechanical feeding.

[0046] 102. Drive the turntable 40 to rotate, driving the carrier seat 41 carrying the hanger body 100 to rotate to the first sleeving station 22. In this embodiment, the drive motor 72 of the second drive assembly 70 drives the drive gear 71 to rotate, driving the turntable 40 to rotate, so that the carrier seat 41 at the feeding station 21 rotates to the first sleeving station 22.

[0047] 103. Drive the grasping unit 53 to act and grasp the sealing ring 521 at the bottom of the blanking rack 52. At this time, grasp the first sealing ring 521. In this embodiment, the initial position of the grasping unit 53, that is, the grasping part 5321 of the elastic piece 532 in the grasping unit 53 extends into the blanking rack 52 and is inserted into the gap between two adjacent sealing rings 521 at the bottom of the blanking rack 52. When the carrier seat 41 carrying the hanger body 100 rotates to the first sleeving station 22, the drive cylinder 534 winds up the connecting rope 533, driving the connecting part of the elastic piece 532 to expand outwards. At the same time, the expansion airbag 535 expands, thereby grasping the sealing ring 521 at the bottom of the blanking rack 52. At this time, the grasping of the first sealing ring 521 is completed.

[0048] 104. Drive the grasping unit 53 to descend, driving the sealing ring 521 to descend to the first sealing groove 11 of one of the ring groove groups 10 of the hanger body 100. In this embodiment, the lifting cylinder 54 drives the grasping unit 53 to descend, driving the first grasped sealing ring 521 to descend to the first sealing groove 11 of one of the ring groove groups 10 of the hanger body 100. At this time, the first sealing ring 521 grasped by the grasping unit 53 is located outside the first sealing groove 11.

[0049] 105. Drive the grasping unit 53 to release the sealing ring 521, so that the sealing ring 521 is automatically sleeved in the first sealing groove 11, completing the sleeving of the first sealing ring 521. In this embodiment, the drive cylinder 534 releases the connecting rope 533, so that the abutting part 5322 of the elastic piece 532 automatically rebounds, driving the grasping part 5321 of the elastic piece 532 to contract inwards. At this time, the air source 536 also synchronously sucks out the gas in the expansion airbag 535, causing the expansion airbag 535 to contract, thereby releasing the sealing ring 521, and then enabling the sealing ring 521 to be automatically sleeved in the first sealing groove 11. At this time, the sleeving of the first sealing ring 521 is completed.

[0050] 106. Drive the grasping unit 53 to rise and grasp the sealing ring 521 at the bottommost side of the blanking rack 52. At this time, grasp the second sealing ring 521.
