Description

Technical Field

[0001] The utility model relates to the field of welding structures, and more specifically, to a welding structure of a ship pressure vessel. Background Art

[0002] Marine pressure vessel welded structures are containers used to carry and store pressurized gas or liquid media on ships. They are primarily constructed by joining various metal materials (such as steel plates and pipes) together through welding processes. These vessels play an indispensable role in a variety of critical systems, including the ship's power system, cargo storage and transportation system, and fire protection system.

[0003] In a busy and complex welding site environment, due to the influence of various welding operations and surrounding work activities, there may inevitably be some extremely tiny metal particles, impurities and other foreign matter. When the tank body starts to rotate, it will produce relative motion with the outer roller, and these tiny foreign matter may be drawn into the gap between the tank body and the roller. As the tank body continues to rotate, these foreign matter entering the gap will come into contact with the inner surface of the tank body under the action of friction, causing scratches and friction, which will have a potential impact on the quality and performance of the tank body. Therefore, a ship pressure vessel welding structure with a protective mechanism is designed to solve the above problems. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] In response to the problems existing in the prior art, the purpose of the present utility model is to provide a ship pressure vessel welding structure. In this scheme, a universal shaft ball rotatably connected to the arc groove is set at the end position of the elastic corrugated stretching surface tube. The universal shaft ball can facilitate the flexible adaptation of the self-adaptive fitting surface and the inclination of the cylindrical container semi-finished product to each other, so that the gap position between the elastic corrugated stretching surface tube and the cylindrical container semi-finished product is reduced to the greatest extent, avoiding foreign matter from entering the contact area between the roller and the cylindrical container semi-finished product during welding, which may cause scratches or protrusions on the surface of the cylindrical container semi-finished product, and effectively ensuring the welding effect.

[0006] 2. Technical solution

[0007] In order to solve the above problems, the present invention adopts the following technical solutions.

[0008] A ship pressure vessel welding structure includes a welding platform, and two groups of docking and positioning components are provided at the upper end of the welding platform. The docking and positioning components include load-bearing horizontal bars that are symmetrically arranged on the left and right. The front and rear sides of the upper end of the load-bearing horizontal bars are symmetrically fixedly connected to external brackets. A roller driving component is installed on the upper end of the external bracket. The front and rear ends of the external bracket are symmetrically fixedly connected to external oblique protruding rods. A connecting bar is fixedly connected between the two external oblique protruding rods. The connected bar is located on the side away from the roller driving component. The upper and lower ends of the connecting bar are symmetrically fixedly connected to elastic corrugated tensile surface tubes. The elastic corrugated tensile surface tubes are provided with multiple arc grooves at one end away from the connecting bar. The inner end of the arc groove is rotatably connected to a universal shaft ball, and the end of the universal shaft ball away from the arc groove is fixedly connected to a self-adaptive fitting surface.

[0009] Furthermore, the multiple arc-shaped grooves are evenly spaced from front to back, and the roller drive member is externally connected to a drive device.

[0010] Furthermore, a pair of electric guide rails are fixedly connected to the front side of the upper end of the welding platform, and the electric guide rails are connected to the corresponding docking positioning components.

[0011] Furthermore, a cylindrical container semi-finished product is respectively installed on the upper ends of the two groups of docking and positioning components, and the outer wall surface of the cylindrical container semi-finished product is rotationally connected to the roller driving component.

[0012] Furthermore, the self-adaptive fitting surface cooperates with the outer side wall of the semi-finished cylindrical container, and a replaceable friction-resistant surface layer is provided at one end of the self-adaptive fitting surface away from the universal joint ball.

[0013] Furthermore, the replacement friction-resistant surface layer and the universal joint ball are detachably connected, and the replacement friction-resistant surface layer and the outer wall surface of the semi-finished cylindrical container are fitted together.

[0014] Furthermore, a welding head is externally connected to the left side of the welding platform, and an output end of the welding head cooperates with ends of the two cylindrical container semi-finished products that are close to each other.

[0015] 3. Beneficial effects

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] (1) During the welding process of this solution, the two elastic corrugated stretching surface tubes will enclose a large area of ​​the outside of the roller drive component. A universal shaft ball that is rotatably connected in the arc groove can also be set at the end position of the elastic corrugated stretching surface tube. The universal shaft ball can facilitate the flexible adaptation of the self-adaptive fitting surface and the inclination of the cylindrical container semi-finished product, so that the gap position between the elastic corrugated stretching surface tube and the cylindrical container semi-finished product is minimized to the greatest extent, and the protection of the elastic corrugated stretching surface tube for the roller drive component is enhanced, avoiding foreign matter from entering the contact area between the roller and the cylindrical container semi-finished product during welding, which may cause scratches or protrusions on the surface of the cylindrical container semi-finished product, and effectively ensuring the welding effect.

[0018] (2) At the same time, a replacement friction-resistant surface layer can be provided between the self-adaptive fitting surface and the cylindrical container semi-finished product as a consumable part. The replacement friction-resistant surface layer can serve as a barrier surface between the self-adaptive fitting surface and the cylindrical container semi-finished product. After the cylindrical container semi-finished product and the self-adaptive fitting surface have been used for a period of time, the worn replacement friction-resistant surface layer can be directly replaced without causing wear damage to the self-adaptive fitting surface, thereby improving the service life of the self-adaptive fitting surface.

[0030] See also Figure 1-4In this solution, the two pre-processed semi-finished cylindrical containers 6 are hoisted on the two docking positioning components 2 above the welding platform 1, and the electric guide rail 3 drives the docking positioning components 2 at the corresponding position to move so that the two outer oblique protruding rods 8 are accurately aligned.
