Description

Technical Field

[0001] The present application belongs to the technical field of studs, and in particular to a corrosion-resistant stud for an offshore platform. Background Art

[0002] Studs refer to a type of fastener that has no head and only external threads on both ends, such as double-ended studs and welding studs. Offshore platforms are a common type of marine engineering equipment. During the construction of offshore platforms, studs are often used to connect objects.

[0003] When the existing studs are in use, most of the existing studs do not have the function of corrosion prevention and rust prevention. Therefore, when the studs are exposed to the outside world, they are easily corroded by rain or sea water, which causes the studs to rust or corrode, causing the studs to be damaged, reducing the stability of the object connection, and causing the studs to be unable to meet the use requirements in seawater.

[0004] To this end, we propose a corrosion-resistant stud for offshore platforms to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-5 A corrosion-resistant stud for an offshore platform comprises a stud body 1. The outer surface of the stud body 1 is respectively sleeved with a first sealing tube 2 and a second sealing tube 3. A sealing block 13 is fixedly installed on the left side of the first sealing tube 2. A connecting groove 14 is opened on the right side of the second sealing tube 3. The sealing block 13 is clamped in the inside of the connecting groove 14. The installation of the sealing block 13 and the connecting groove 14 plays a role in sealing the connecting gap between the first sealing tube 2 and the second sealing tube 3, thereby increasing the sealing performance of the connection between the first sealing tube 2 and the second sealing tube 3.

[0023] Two groups of fixing blocks 4 are fixedly installed on the outer surface of the first sealing tube 2, and a connecting block 5 is fixedly installed on the left side of each fixing block 4. Two gaskets 10 are sleeved on the outer surface of the stud body 1, and the bottom surface of each gasket 10 is in contact with the upper surface of the first sealing tube 2. The installation of the gasket 10 reduces the wear of the first sealing tube 2 and the second sealing tube 3 caused by external objects when the stud body 1 is in use, thereby further increasing the service life of the device.

[0024] Two sets of connection boxes 6 are fixedly installed on the outer surface of the second sealing tube 3, and each connection block 5 is clamped in the inside of the connection box 6. The outer surface of the first sealing tube 2 is fixedly installed with a first waterproof coating 11, and the outer surface of the second sealing tube 3 is fixedly installed with a second waterproof coating 12. The first waterproof coating 11 and the second waterproof coating 12 are made of materials such as epoxy resin and have good waterproof performance, so as to avoid contact between seawater and the stud body 1 as much as possible.

[0025] Two connecting springs 7 are fixedly installed on the inner wall of each connecting box 6, and a wedge block 8 is fixedly installed on the end of each group of connecting springs 7 close to the stud body 1, and each wedge block 8 is clamped in the inside of the connecting block 5. A slider 15 is fixedly installed on the upper surface and the bottom surface of each wedge block 8. A slide groove 16 is provided on the inner top wall and the inner bottom wall of each connecting box 6, and each slider 15 is slidably connected to the inside of the slide groove 16. The shape of the slider 15 is T-shaped, and the shape of the slide groove 16 matches the shape of the slider 15. The installation of the slider 15 and the slide groove 16 plays a role in limiting the moving trajectory of the wedge block 8, thereby minimizing the phenomenon that the wedge block 8 deviates from the moving trajectory during movement, thereby ensuring the stability of the movement of the wedge block 8.

[0026] A pull rod 9 is fixedly installed on one end of each wedge block 8 away from the stud body 1, and each pull rod 9 passes through the connecting box 6 and is fixedly installed with a connecting column 18 on one end away from the wedge block 8. A pull ring 19 is rotatably connected to the inside of each connecting column 18. The installation of the connecting column 18 and the pull ring 19 makes it convenient for workers to pull the pull rod 9, thereby reducing the complexity of the workers' operation.

[0027] A sealing gasket 17 is fixedly installed on the side of each connection box 6 away from the stud body 1, and the inner wall of each sealing gasket 17 is slidably connected to the outer surface of the pull rod 9. The installation of the sealing gasket 17 seals the connection between the pull rod 9 and the connection box 6, thereby preventing seawater from entering the interior of the connection box 6 through the gap as much as possible.

[0028] The working principle of the utility model is as follows: when in use, the worker first sleeves the first sealing tube 2 and the second sealing tube 3 on the outer surface of the stud body 1, and inserts the connecting block 5 into the interior of the connecting box 6, and inserts the sealing block 13 into the interior of the connecting groove 14, so that when the connecting block 5 extends into the interior of the connecting box 6, the connecting block 5 pushes the wedge block 8 to compress the connecting spring 7. When the connecting block 5 completely enters the interior of the connecting box 6, under the action of the elastic force of the connecting spring 7, the wedge block 8 is pushed to move to the side close to the stud body 1, so that the wedge block 8 is clamped in the interior of the connecting block 5, thereby locking the connecting block 5, and then fixing the first sealing tube 2 and the second sealing tube 3 on the outer surface of the stud body 1. After that, the worker sleeves the gasket 10 on the two ends of the stud body 1 respectively, and installs the stud body 1 on the object to be connected, so that the device has good corrosion resistance under the isolation effect of the first sealing tube 2 and the second sealing tube 3, thereby increasing the service life of the device.
