Description

Technical Field

[0001] The invention belongs to the field of offshore oil engineering construction and installation, and in particular relates to an auxiliary tooling for installing a riser clip rubber. Background Art

[0002] In marine engineering equipment, riser clips are used to protect marine engineering risers, which are important devices for transporting oil and natural gas from the seabed to the platform for processing. They are usually composed of two semicircular tubes with rubber installed inside to form a pair of clamps to fix and protect the riser. Due to the harsh environment in which the riser is located, it is very easy to be damaged and defective, such as collision, wave frequency vibration, vortex-induced vibration, parametric vibration, etc. Therefore, during the prefabrication process of the riser clip, the reliability of the rubber installation is very high, and no bubble defects are allowed.

[0003] At present, during on-site rubber pasting operations, scrapers are usually used to remove bubbles. Since the rubber is hard and thick, and the pasting area is large, the labor intensity of the rubber pasting workers is high, the construction efficiency is low, and it is difficult to ensure the technical quality, which restricts the progress of on-site construction.

[0004] Therefore, it is urgent to design an auxiliary tooling for installing the riser clip rubber to solve the problem of bubbles in the riser clip rubber mentioned above. Summary of the invention

[0005] In order to solve the technical problems that the on-site rubber pasting operation mentioned in the background technology uses a scraper to remove bubbles, but the rubber is hard in texture, thick in thickness, and has a large pasting area, which leads to high labor intensity for the rubber pasting workers, low construction efficiency, and difficulty in ensuring technical quality, an auxiliary tooling for the installation of the rubber of the riser clip is provided to solve the problem of bubbles in the rubber pasted by the riser clip.

[0006] To achieve the above-mentioned purpose, the specific technical scheme of the auxiliary tooling for installing the riser clip rubber of the present invention is as follows: An auxiliary tooling for installing the rubber of a riser clamp includes a fastening shaft, the fastening shaft abuts against the rubber, the rubber is adhered to the riser clamp, and the fastening shaft is rotated to discharge the bubbles between the rubber and the riser clamp; both ends of the fastening shaft are connected to end bearings, the end bearings are connected to a first screw, and the first screw is connected to a follower shaft, the follower shaft abuts against the side of the riser clamp away from the rubber, and the follower shaft moves as the fastening shaft rotates.

[0007] Furthermore, both ends of the fastening shaft are hinged with end bearings, and the end bearings abut against the side walls of the riser clamp.

[0008] Furthermore, a rotating disk is connected to the side of the end bearing away from the fastening bearing, and the rotating disk is rotated to rotate the fastening bearing.

[0009] Furthermore, the end bearing is connected to a first connecting pipe, and a first screw is threadedly connected in the first connecting pipe.

[0010] Furthermore, a first nut is threadedly connected to the first screw rod, and a follower shaft is connected to the first nut.

[0011] Furthermore, a second connecting tube is connected to the first nut, and the follower shaft is screwed to the second connecting tube via a second screw rod.

[0012] Furthermore, a second nut is threadedly connected to the first screw rod, and the second nut is tightened to make the follower shaft abut against the riser clamp.

[0013] Furthermore, the second nut is threadedly connected to a side of the first nut away from the first connecting pipe.

[0014] Furthermore, the second screw is hinged to the follower shaft at one side away from the second connecting pipe.

[0015] Furthermore, the central axis of the first screw is perpendicular to the central axis of the fastening shaft.

[0016] The auxiliary tooling for installing the riser clip rubber of the present invention has the following advantages: The follow-up shaft can automatically adapt to different riser diameters, wall thicknesses and rubber wall thicknesses. At the same time, the size of the fastening shaft is replaceable and can match riser clips of different sizes. After the rubber and the riser clip are initially fitted, the tooling is fixed to one side of the rubber, and the fastening shaft is rotated by the turntable to squeeze out the bubbles in the rubber from one side to the other, so that the rubber and the riser clip can be quickly fitted. This application greatly facilitates the rubber installation process, shortens the construction period, and ensures the welding quality of the riser clip, reduces the impact of adverse factors such as squeeze injuries to personnel, damage to parent materials, and high labor intensity of operators during construction, and can be installed and reused, saving manpower and financial resources to ensure construction progress.

[0023] The follow-up rotating shaft 7 can automatically adapt to different riser diameters, wall thicknesses and wall thicknesses of the rubber 2. At the same time, the size of the fastening rotating shaft 1 is replaceable and can match riser clips 3 of different sizes. After the rubber 2 and the riser clip 3 are initially fitted, the tooling is fixed to one side of the rubber 2, and the fastening rotating shaft 1 is rotated by a turntable to squeeze out the bubbles of the rubber 2 from one side to the other, so that the fitting of the rubber 2 and the riser clip 3 can be completed quickly. This application greatly facilitates the installation process of the rubber 2, shortens the construction period, and ensures the welding quality of the riser clip 3, reduces the impact of adverse factors such as squeeze injuries to personnel, damage to the parent material, and high labor intensity of operators during the construction process, can be installed and reused, saves manpower and financial resources, and ensures the construction progress.

End bearings 4 are hinged at both ends of the fastening shaft 1, and the end bearings 4 at both ends are abutted against the ends of the riser clamp 3, so that the fastening shaft 1 rotates along the arc surface of the riser clamp 3, so that the bubbles between the rubber 2 and the riser clamp 3 are squeezed out.

[0026] Since the structures of the end bearings 4 on both sides of the fastening shaft 1 are the same, only one side of the fastening shaft 1 will be described below.

[0027] A turntable 8 is welded on the side of the end bearing 4 away from the fastening shaft 1. The construction personnel rotate the turntable 8 to rotate the fastening shaft 1 from one end of the riser clamp 3 to the other end, so that all the bubbles between the rubber 2 and the riser clamp 3 are discharged.

[0028] Further, if Figure 1 As shown, a first nut 10 is screwed onto the first screw rod 5, and a follower shaft 7 is connected to the first nut 10; a second connecting pipe is connected to the first nut 10, and the follower shaft 7 is screwed onto the second connecting pipe through a second screw rod 6; a second nut 10 is screwed onto the first screw rod 5, and the second nut 11 is tightened to make the follower shaft 7 abut against the riser clamp 3.

The second nut 11 is screwed along the first screw rod 5 to adjust the distance between the follow-up shaft 7 and the fastening shaft 1, so that the bubble discharge work of the rubber 2 can be performed for the riser clamps 3 of various thicknesses; the second nut 11 is tightened to ensure that the follow-up shaft 7 always abuts against the outer wall of the riser clamp 3, so that the fastening shaft 1 always abuts against the rubber 2.

[0031] Further, if Figure 1 As shown, the second nut 11 is screwed on the side of the first nut 10 away from the first connecting pipe 9; the second screw rod 6 is hinged to the follower shaft 7 on the side away from the second connecting pipe; the central axis of the first screw rod 5 is perpendicular to the central axis of the fastening shaft 1.

[0032] In this embodiment, preferably, the second nut 11 is screwed on the side of the first nut 10 away from the first connecting pipe 9 to achieve the tightening of the follower shaft 7; the follower shaft 7 is hinged on the second screw rod 6, so that when the tightening shaft 1 rotates, the follower shaft 7 always abuts against the riser clamp 3.
