[0039] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0041] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components.

[0042] The technical solution of the present application will be further described below in conjunction with specific embodiments and drawings.

[0043] See also Figure 1 The embodiment of the present application provides a lifting device 1, including a lifting rope 11 and a lifting assembly 12. The lifting assembly 12 includes a bearing component 121, a locking pin component 122 and a locking block 123. The bearing component 121 is provided with a first hole 1212a and a second hole 1213a, the first hole 1212a and the second hole 1213a are coaxial, and a gap 1214 capable of accommodating the flange edge of the blowout preventer is formed between the first hole 1212a and the second hole 1213a, and the bearing component 121 is connected to the lifting rope 11. The locking pin component 122 is configured such that when the flange edge of the blowout preventer is accommodated in the gap 1214, the locking pin component 122 can be inserted into the first hole 1212a, the diagonal screw hole provided on the flange edge and the second hole 1213a. The locking block 123 is connected to the bearing component 121 and is used to lock the locking pin component 122 when the locking pin component 122 passes through the first hole 1212a, the diagonal screw hole provided on the edge of the flange, and the second hole 1213a.

[0044] The suspension rope 11 may be a steel wire rope or a chain, etc., which is not limited here.

[0045] The working principle of the present application is to move the bearing component 121 to the flange edge of the blowout preventer so that the flange edge is accommodated in the gap 1214, and at the same time adjust the diagonal screw hole of the flange edge to be coaxial with the first hole 1212a. Since the first hole 1212a is coaxial with the second hole 1213a, the diagonal screw hole is coaxial with the second hole 1213a.

[0046] After the diagonal screw hole is coaxial with the first hole 1212a, the locking pin component 122 is moved so that part or at least part of the locking pin component 122 is sequentially passed through the first hole 1212a, the diagonal screw hole and the second hole 1213a, and the locking block 123 locks the locking pin component 122, so that the hanging assembly 12 is stably installed on the diagonal screw hole of the flange edge of the blowout preventer.

[0047] After the hoisting assembly 12 is installed on the flange edge of the blowout preventer, the hoisting assembly 12 is hoisted by the hoisting rope 11, thereby hoisting the blowout preventer.

[0048] In summary, since the lifting rope 11 of the present application is connected to the bearing component 121, compared with the prior art in which the lifting rope 11 is sleeved on the bolts installed on the diagonal screw holes of the flange, the lifting rope 11 of the present application will not slip, and at the same time, the locking block 123 locks the locking pin component 122, so that the connection stability between the lifting assembly 12 and the blowout preventer is strong, avoiding the mutual separation between the lifting assembly 12 and the blowout preventer, and ensuring the safety of lifting the blowout preventer.

[0049] Please continue reading Figure 1 In some embodiments, the locking pin component 122 includes a locking pin 1221 and a baffle 1222. The locking pin 1221 is in a preset position when the edge of the flange is accommodated in the gap 1214, wherein the locking pin 1221 in the preset position is penetrated through the first hole 1212a, the diagonal screw hole provided on the edge of the flange, and the second hole 1213a. The baffle 1222 is connected to one end of the locking pin 1221 and is locked by the locking block 123 when the locking pin 1221 is in the preset position.

[0050] In this embodiment, when the locking pin 1221 is in the preset position, the locking block 123 locks the baffle 1222, thereby achieving the function of locking the locking pin 1221, preventing the locking block 123 from directly acting on the locking pin 1221, and avoiding the locking pin 1221 from being broken due to the force applied by the blowout preventer to the locking pin 1221 when the locking pin 1221 passes through the diagonal screw hole on the edge of the flange.

[0051] In some other embodiments, the locking block 123 may also directly lock the locking pin 1221 .

[0052] In some embodiments, when the locking pin 1221 is at a preset position, the baffle 1222 is located between the locking block 123 and the first hole 1212 a , and the locking block 123 abuts against a surface of the baffle 1222 facing away from the locking pin 1221 to lock the baffle 1222 .

[0053] In this embodiment, in the direction perpendicular to the axial direction of the locking pin 1221, the size of the baffle 1222 is larger than the aperture of the first hole 1212a. When the locking pin 1221 is inserted into the first hole 1212a, the diagonal screw hole provided on the flange edge and the second hole 1213a, the baffle 1222 can abut against the bearing component 121, thereby limiting the position of the baffle 1222 in the direction from the first hole 1212a to the second hole 1213a. At the same time, the locking block 123 abuts against the surface of the baffle 1222 away from the locking pin 1221, thereby limiting the position of the baffle 1222 in the direction from the second hole 1213a to the first hole 1212a, thereby locking the position of the locking pin 1221 in the axial direction of the first hole 1212a, thereby ensuring the stability of the connection between the lifting assembly 12 and the blowout preventer.

[0054] In some other embodiments, the locking block 123 can be inserted into the side wall of the baffle 1222 .

[0055] In some more specific embodiments, a locking groove 1222 a is provided at the edge of the baffle 1222 , and the locking groove 1222 a penetrates the baffle 1222 along the axial direction of the locking pin 1221 , and the locking groove 1222 a is used to avoid the locking block 123 .

[0056] The working principle of this embodiment is that the end of the locking pin 1221 away from the baffle 1222 is inserted into the first hole 1212a, the diagonal screw hole arranged on the edge of the flange and the second hole 1213a in sequence, so that the locking block 123 passes through the locking groove 1222a. At this time, the baffle 1222 is rotated along the axis of the locking pin 1221, so that the locking block 123 and the locking groove 1222a are staggered with each other in the axial direction of the locking pin 1221, so that the locking block 123 and the surface of the baffle 1222 facing away from the locking pin 1221 are abutted.

[0057] In some other embodiments, the locking block 123 can also be movably arranged. When the end of the locking pin 1221 away from the baffle 1222 successively passes through the first hole 1212a, the diagonal screw hole provided on the edge of the flange and the second hole 1213a, the locking block 123 is outside the path of the baffle 1222. When the locking pin 1221 is in a preset position, the locking block 123 switches to a position abutting against the surface of the baffle 1222 away from the locking pin 1221.

[0058] Please continue reading Figure 1In some more specific embodiments, the locking pin component 122 further includes a handle 1223 , which is connected to the baffle 1222 and is located on a side of the locking pin 1221 away from the baffle 1222 .

[0059] The staff can hold the handle 1223 to move the locking pin 1221 into the first hole 1212a, the diagonal screw hole and the second hole 1213a in sequence, or move the locking pin 1221 out of the second hole 1213a, the diagonal screw hole and the first hole 1212a in sequence, which is convenient for the staff to operate.

[0060] In some other more specific embodiments, the handle 1223 can be disposed on the side wall of the baffle 1222 .

[0061] Please continue reading Figure 1 In some more specific embodiments, the locking pin component 122 further includes a chain 1224 , one end of the chain 1224 is connected to the bearing component 121 , and the other end of the chain 1224 is connected to the side wall of the baffle 1222 .

[0062] In this embodiment, the baffle 1222 is connected to the bearing component 121 through the chain 1224, and there is no need to separately store the locking pin part, which is convenient for the staff to operate.

[0063] In some other more specific embodiments, the chain 1224 may also be connected to the bottom wall where the baffle 1222 is connected to the side wall.

[0064] Please continue reading Figure 1 In some embodiments, the bearing member 121 includes a connecting member 1211, a locking member 1212 and a bearing member 1213. The connecting member 1211 is connected to the sling 11. The locking member 1212 is connected to the connecting member 1211, and the locking member 1212 is provided with a first hole 1212a, and the first hole 1212a penetrates the locking member 1212. The bearing member 1213 is connected to the connecting member 1211, and the bearing member 1213 is spaced apart from the locking member 1212 along the axial direction of the first hole 1212a, and a second hole 1213a is provided on the surface of the bearing member 1213 facing the locking member 1212. The locking block 123 is provided on the connecting member 1211, and is located on the side of the locking member 1212 away from the bearing member 1213, and the locking block 123 is spaced apart from the locking member 1212.

[0065] The second hole 1213a may be a through hole of the carrier 1213 or a blind hole that does not penetrate the carrier 1213 , which is not limited here. In addition, the gap 1214 is located between the locking member 1212 and the carrier 1213 .

[0066] It can be understood that, in this embodiment, when the hoisting assembly 12 is installed on the flange edge of the blowout preventer and hoisted, the surface of the bearing member 1213 facing the connecting member 1211 abuts against the flange, thereby achieving the purpose of bearing the blowout preventer. In addition, the inner wall of the diagonal screw hole formed by the flange may exert a shear stress parallel to the radial direction of the first hole 1212a on the lock pin member 122, so that there is a large pressure between the lock pin member 122 and the inner wall forming the first hole 1212a, so that a large first friction force is formed between the lock pin member 122 and the inner wall forming the first hole 1212a, and similarly, there is also a large pressure between the lock pin member 122 and the inner wall forming the second hole 1213a, so that a large second friction force is also formed between the lock pin member 122 and the inner wall forming the second hole 1213a, and the first friction force and the second friction force can limit the lock pin member 122 in the axial direction of the first hole 1212a.

[0067] In some other embodiments, the sling 11 can be connected to the locking member 1212 .

[0068] In some embodiments, one surface of the locking block 123 is connected to the connecting member 1211 , and the other surface is connected to the locking member 1212 .

[0069] In this embodiment, the locking block 123 is connected to the connecting member 1211 and the locking member 1212, which can improve the stability of the locking block 123, thereby improving the locking function of the locking block 123 to lock the locking pin component 122 and preventing the locking block 123 from detaching from the supporting component 121.

[0070] In some other embodiments, the locking block 123 may be only provided on the connecting member 1211 or the locking member 1212 .

[0071] Please continue reading Figure 1 In some more specific embodiments, the bearing component 121 further includes an ear plate 1215 , the ear plate 1215 is connected to the connecting member 1211 , and the ear plate 1215 is connected to the suspension rope 11 .

[0072] The ear plate 1215 is a connecting component, and the lifting rope 11 is connected to the ear plate 1215. During the lifting process, the ear plate 1215 can withstand greater tension and enhance the stability of the connection between the lifting rope 11 and the lifting assembly 12. At the same time, the lifting rope 11 is indirectly connected to the connecting member 1211, which can prevent the lifting rope 11 from directly applying a force to the connecting member 1211, thereby protecting the connecting member 1211.

[0073] In some other more specific embodiments, the sling 11 can be directly connected to the connecting piece 1211 .

[0074] See also Figure 2In some embodiments, the number of the lifting components 12 and the number of the lifting ropes 11 are at least four, and the lifting ropes 11 correspond to the bearing components 121 one by one.

[0075] It is understandable that, due to the heavy weight of the blowout preventer, multiple hoisting assemblies 12 are required for lifting so that the weight of the blowout preventer can be dispersed among the multiple hoisting assemblies 12, thereby reducing the force on a single hoisting assembly 12 and a single hoisting rope 11, avoiding the single hoisting assembly 12 and a single hoisting rope 11 from being damaged by a large force, effectively protecting the hoisting assembly 12 and the hoisting rope 11, and extending the service life of the hoisting assembly 12 and the hoisting rope 11. At the same time, hoisting the blowout preventer with multiple hoisting assemblies 12 can ensure that the blowout preventer is subjected to a more stable and uniform tension during the hoisting process, thereby avoiding the blowout preventer from tilting, shaking or rotating during the hoisting process, thereby improving the safety and stability of the hoisting process.

[0076] In some other embodiments, the number of the hanging components 12 and the hanging ropes 11 may be less than four.

[0077] Please continue reading Figure 2 In some embodiments, the lifting device 1 further includes a lifting ring 13 , and one end of at least four lifting ropes 11 away from the bearing component 121 is connected to the lifting ring 13 .

[0078] One end of at least four lifting ropes 11 away from the bearing component 121 is connected to the lifting ring 13. Only by lifting the lifting ring 13, at least four lifting assemblies 12 can be lifted by at least four lifting ropes 11, thereby achieving the purpose of lifting the blowout preventer. There is no need to lift a single lifting rope 11 separately, which simplifies the lifting process and improves the lifting efficiency.

[0079] In some other embodiments, one end of each suspension rope 11 away from the bearing component 121 may be connected to a suspension ring 13 .

[0080] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
