Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of cabin-penetrating fittings of installation ship pipeline and ship pipeline. BACKGROUND

[0002] When laying pipeline, ship may encounter the obstruction of deck or bulkhead, generally, a cabin hole is opened on deck or bulkhead, and a cabin-penetrating fitting is installed therein to connect the pipelines on both sides of deck or bulkhead. Specifically, the cabin-penetrating fitting comprises a steel pipe, flanges, a protective sleeve and a web. The specific structure is that the steel pipe is connected by flanges at both ends, the protective sleeve is outside the steel pipe, and the web is outside the protective sleeve. Except for the web, which is welded on the ship, all other connecting parts are welded, and then galvanized or pickled and phosphatized, and then painted, to resist the corrosion of seawater and ensure the normal use of the pipeline.

[0003] At present, when installing the cabin-penetrating fitting, the sleeve is usually welded to the ship. However, there is no force applying component between the sleeve and the ship during welding, and the cabin-penetrating fitting is only horizontally placed by its own gravity at the connecting position, which is inevitably loose, affecting the normal welding of workers, reducing the installation efficiency, and making it difficult to ensure the quality.

[0004] Therefore, it is necessary to invent a cabin-penetrating fitting for installing ship pipeline to solve the above problems. CONTENT OF THE UTILITY MODEL

[0005] (I) OBJECT OF THE UTILITY MODEL

[0006] To solve the technical problems in the background art, the utility model provides a cabin-penetrating fitting for installing ship pipeline and a ship pipeline. When the sleeve is inserted into the cabin hole, the top block is pressed into the hole by the inner wall of the cabin hole, the spring is shortened at this time, and when the top block cannot move, it exerts a pushing force on the inner wall of the cabin hole under the action of the spring elasticity, so that the friction between the sleeve and the inner wall of the cabin hole increases, the sleeve can be stably placed inside the cabin hole, and the workers can easily weld the web on the ship. The installation efficiency and quality of the whole cabin-penetrating fitting are high.

[0007] (II) TECHNICAL SCHEME

[0008] To achieve the above purpose, the utility model provides the following technical scheme: a cabin-penetrating fitting for installing ship pipeline, which is installed inside the cabin hole of a ship, comprising a steel pipe, a sleeve arranged outside the steel pipe, a web arranged outside the sleeve, and flanges installed at both ends of the steel pipe.

[0009] The sleeve has several through holes on its outer side, and a top block is installed inside each through hole. A pushing component is provided inside the sleeve to push each top block to move toward the outside of the sleeve and press against the ship.

[0010] Preferably, the pushing assembly includes a clearance groove formed on the inner wall of the sleeve, a movable plate installed inside the clearance groove, a push plate connected to one side of the movable plate, and a spring disposed inside the clearance groove. The spring is disposed on the side of the movable plate away from the push plate and is used to drive the movable plate to slide toward the push plate.

[0011] Preferably, the clearance groove, the movable plate, and the push plate are all configured as annular, and the push plate has a first inclined section on the side away from the movable plate.

[0012] Preferably, each of the top blocks is provided with a second inclined section on the side adjacent to the push plate, and the first inclined section and the second inclined section are adapted to each other.

[0013] Preferably, each of the top blocks has a third inclined section on the side away from the push plate, the bottom of the third inclined section is located inside the through hole, and the inclination angle of the third inclined section is the same as that of the second inclined section.

[0014] Preferably, each of the top blocks is connected to a slider on the side away from the push plate.

[0015] Preferably, the through holes are evenly spaced in a ring array inside the sleeve, and the sidewall of the sleeve at each through hole is provided with a groove for sliding of the slide plate.

[0016] A ship piping system, using the through-cabin fitting of this utility model for installing ship piping.

[0017] Compared with the prior art, the beneficial effects of the above-mentioned technical solution of this utility model are:

[0018] This utility model incorporates a spring, a movable plate, a push plate, and a top block. When the sleeve is inserted into the hull hole, the top block is pressed into the through hole by the inner wall of the hull hole, causing the spring to contract and shorten. When the top block cannot move, the spring applies an elastic force to the movable plate, which is then transmitted through the push plate. At this point, the top block applies a thrust to the inner wall of the hull hole, increasing the pressure between the sleeve and the inner wall of the hull hole and increasing the friction between them. This allows the sleeve to remain stably inside the hull hole, preventing it from loosening and facilitating the welding of the web plate to the ship. The entire hull-penetrating component has high installation efficiency and good quality. Attached Figure Description

[0033] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0034] This utility model provides, for example Figures 1-9The diagram shows a through-hole fitting for installing ship piping, installed inside the ship's hull opening, comprising a steel pipe 1, a sleeve 2 sleeved on the outside of the steel pipe 1, a web plate 3 sleeved on the outside of the sleeve 2, and flanges 4 installed at both ends of the steel pipe 1.

[0035] The sleeve 2 has several through holes 5 on its outer side, and a top block 6 is installed inside the through hole 5. A pushing assembly 7 is provided inside the sleeve 2 to push each top block 6 to move towards the outside of the sleeve 2 and press against the ship. The pushing assembly 7 includes a relief groove 71 opened on the inner wall of the sleeve 2, a moving plate 72 installed inside the relief groove 71, a push plate 73 connected to one side of the moving plate 72, and a spring 74 provided inside the relief groove 71. The spring 74 is located on the side of the moving plate 72 away from the push plate 73 and is used to drive the moving plate 72 to slide towards the push plate 73.

[0036] In one embodiment, the clearance groove 71, the movable plate 72, and the push plate 73 are all annular. The push plate 73 has a first inclined section 75 on the side away from the movable plate 72. Each top block 6 has a second inclined section 76 on the side adjacent to the push plate 73. The first inclined section 75 and the second inclined section 76 are adapted to each other. Each top block 6 has a third inclined section 77 on the top of the side away from the push plate 73. The bottom of the third inclined section 77 is located inside the through hole 5. The third inclined section 77 has the same inclination angle as the second inclined section 76. The design of section 75 and the second inclined section 76 allows the original horizontal thrust of the push plate 73 when pushing the top block 6 to be decomposed into a horizontal and a vertical component force. This allows the push plate 73 to push the top block 6 towards the outside of the through hole 5. When the through-hole component is not installed, the top block 6 is always outside the sleeve 2 under the action of the spring force of the spring 74. The design of the second inclined section 76 allows the top block 6 to be forced to move towards the inside of the through hole 5 under the limitation of the inner wall of the cabin hole when the steel pipe 1 is inserted, ensuring that the top block 6 will not block the insertion of the steel pipe 1.

[0037] In one embodiment, each of the top blocks 6 is connected to a slider 8 on the side away from the push plate 73. The through holes 5 are evenly distributed in a ring array inside the sleeve 2. The sidewall of the sleeve 2 at each through hole 5 is provided with a groove 9 for sliding of the slide plate. The slider 8 can limit the top block 6 so that when the top block 6 moves, its displacement will not exceed the displacement of the slider 8 in the groove 9, thereby ensuring that the top block 6 is always inside the through hole 5 and ensuring the normal use of the top block 6.

[0038] An embodiment of a ship pipeline uses the through-hull fitting of this utility model for installing ship pipelines. Under the action of the spring 74, the top block 6 can increase the friction between the sleeve 2 and the ship, making the sleeve 2 less prone to loosening in the hull hole, which facilitates the quick installation of the entire through-hull fitting by the staff, resulting in fast installation efficiency and high quality.

[0039] The specific implementation method is as follows: When in use, this utility model is installed on a ship, specifically in a hatch in the deck or bulkhead, and the specific installation process is as follows:

[0040] First, the workers put the sleeve 2 on the outside of the steel pipe 1 and push the sleeve 2 to move it along the axial direction of the steel pipe 1. When the position reaches the predetermined position, the sleeve 2 is welded to the steel pipe 1. The web plate 3 is welded to the outside of the sleeve 2 in the same way. Then, the steel pipe 1 is inserted into the hull hole to complete the welding of the web plate 3 to the ship. Finally, flanges 4 are welded on both sides of the steel pipe 1. The assembly is completed by connecting the flanges 4 to the external ship pipeline, and the ship pipeline can then be put into use.

[0041] Furthermore, when the steel pipe 1 is inserted into the cabin opening, the outer side of the sleeve 2 will contact the inner wall of the deck or bulkhead located at the cabin opening. As the steel pipe 1 is continuously inserted, the top block 6, which originally protruded from the outer side of the sleeve 2 under the action of the spring 74, will be pressed against the inner wall at the cabin opening. That is, the insertion of the steel pipe 1 will cause the top block 6 to be subjected to the pressure of the inner wall at the cabin opening, forcing the top block 6 to move along the through hole 5 toward the push plate 73. At this time, the second inclined section 76 at the bottom of the top block 6 will press against the second inclined section 76 of the push plate 73, causing the push plate 73 to move toward the moving plate 72, thereby pushing the moving plate 72 toward the spring 74. The elastic force is compressed and shortened, storing the elastic force.

[0042] When the web plate 3 is in full contact with the deck or bulkhead, the top block 6, under the pressure of the inner wall of the hull opening, has moved completely into the through hole 5. At this point, the welding of the sleeve 2 to the ship can be completed by welding the web plate 3 to the deck or bulkhead. During welding:

[0043] As the spring 74 contracts and shortens, it always exerts a spring force on the moving plate 72 in the direction of the push plate 73. That is, the moving plate 72 has a tendency to push the push plate 73 towards the top block 6, which in turn causes the top block 6 to have a tendency to move along the through hole 5 towards the outside of the sleeve 2. At this time, under the action of the spring force of the spring 74, the top block 6 can apply a thrust to the inner wall of the cabin hole, which increases the pressure between the sleeve 2 and the inner wall of the cabin hole and increases the friction between the two. This allows the sleeve 2 to be stably placed inside the cabin hole and is not easy to loosen. The workers can smoothly complete the welding between the web plate 3 and the ship, thereby improving the installation efficiency of the entire through-hole component and the ship, and the installation quality is high.

[0044] This embodiment specifically addresses the problem that in the current technology, when installing the hull-through component, the sleeve 2 is usually welded to the ship. However, during the welding process, there are no force-applying components between the sleeve 2 and the ship. The hull-through component is horizontal at the connection point only due to its own weight, which inevitably leads to loosening, affecting the normal welding work of the workers, resulting in low installation efficiency and difficulty in guaranteeing quality.

[0045] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
