Abstract
Description
Technical Field
[0001] This utility model relates to the field of marine technology, and more specifically, to a marine pipeline sliding support. Background Technology
[0002] Marine pipe sliding supports, as an important pipe support structure, are mainly used to ensure that pipes can slide freely when heated, thereby avoiding pipe damage caused by stress generated by thermal expansion and contraction. These sliding supports are typically designed to slide freely in a plane to accommodate changes in pipe length.
[0003] However, when the pipe expands due to heat, causing the support installed on the pipe to slide, friction occurs between the support and the mounting components, which is prone to wear. With long-term use, the support is prone to wear and the material cost is high. Utility Model Content

[0030] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.
[0031] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.
[0032] Please refer to Figure 1 and Figure 2 This utility model provides a marine pipe sliding bracket 100 for fixing the exhaust pipe of a ship.
[0033] The marine pipe sliding support 100 includes an upper support 10 and a lower support 30. The lower support 30 is fixed to the hull. One end of the upper support 10 is connected to the lower support 30, and the other end of the upper support 10 is used to fix the pipe 40. A slotted hole 32 is provided on the connecting surface of the upper support 10 and the lower support 30. A sliding washer 34 is provided between the upper support 10 and the lower support 30.
[0034] By creating a slotted hole 32 at the connection surface of the upper support 10 and the lower support 30, relative sliding between them is achieved. When the pipe 40 heats up and expands, it drives the upper support 10 to slide while maintaining the connection. A sliding washer 34 is provided between the upper support 10 and the lower support 30 to prevent wear caused by relative sliding.
[0035] Optionally, in this embodiment, the upper support 10 and the lower support 30 are disposed below the pipe 40 to support and fix the pipe 40. In other embodiments, the upper support 10 and the lower support 30 may be disposed on the side or above the pipe 40 to clamp, fix, or hoist the pipe 40. The specific installation method can be set according to the hull structure. This utility model does not limit the installation method of the marine pipe sliding support 100 relative to the pipe 40.
[0036] Specifically, an arc-shaped plate 20 is provided at the end of the upper support 10 away from the lower support 30. The arc-shaped plate 20 is fixedly connected to the pipe 40. The radius of the arc of the inner wall of the arc-shaped plate 20 is equal to the radius of the pipe 40. It can be understood that by providing the arc-shaped plate 20, the contact area with the pipe 40 is increased, thereby improving the stability of the connection.
[0037] Furthermore, the arc-shaped plate 20 includes a connecting section 21 fixedly connected to the upper support 10 and an extension section 22 extending beyond the upper support 10. It is understood that, in this embodiment, the distance between the two ends of the arc-shaped plate 20 along the direction perpendicular to the axis of the pipe 40 is greater than the width of the upper support 10 along the direction perpendicular to the axis of the pipe 40, in order to further increase the contact area between the arc-shaped plate 20 and the pipe 40 and improve the stability of the connection.
[0038] Specifically, in this embodiment, the arc-shaped plate 20 is located directly below the pipe 40. Extensions 22 are provided at both ends of the arc-shaped plate 20. The extensions 22 at both ends are symmetrically arranged with respect to the central axis of the pipe 40, meaning that the extensions 22 at both ends extend equidistantly from the upper support 10, thus balancing the forces acting on the pipe 40.
[0039] Specifically, the angle of the arc on which the curved plate 20 is located is 90-180°. The thickness of the curved plate 20 is 10-15mm.
[0040] Please refer to Figure 1 and Figure 3 In this embodiment, the upper support 10 includes a vertical plate and a base plate 13. One end of the vertical plate is used to fix the pipe 40, and the other end of the vertical plate is fixedly connected to the base plate 13. The base plate 13 is connected to the lower support 30.
[0041] Specifically, the upright plate includes multiple first upright plates 11 spaced apart along a direction perpendicular to the axis of the pipe 40, and second upright plates 12 perpendicularly connected to the first upright plates 11. Both the first upright plates 11 and the second upright plates 12 are fixedly connected to the base plate 13. The ends of the first upright plates 11 and the second upright plates 12 away from the base plate 13 are used to fix the pipe 40. Specifically, in this embodiment, the tops of the first upright plates 11 and the second upright plates 12 are welded to the pipe 40. The bottoms of the first upright plates 11 and the second upright plates 12 are welded to the base plate 13.
[0042] In this embodiment, three first upright plates 11 are provided. The three first upright plates 11 are spaced apart. Two second upright plates 12 are provided, respectively connected between the first upright plates 11. The first upright plates 11 and the second upright plates 12 are both vertically connected to form a grid, which improves strength and load-bearing capacity. It should be noted that in this embodiment, the first upright plates 11 are spaced apart along a direction perpendicular to the axis of the pipe 40, and the height of the first upright plates 11 decreases and then increases along the direction perpendicular to the axis of the pipe 40 to accommodate the upper arc-shaped plate 20 and cylindrical pipe 40.
[0043] Optionally, in other embodiments, the number of the first upright plate 11 and the second upright plate 12 can be set as needed. For example, the first upright plate 11 can be four or other numbers. This utility model does not limit the number of the first upright plate 11 and the second upright plate 12.
[0044] In this embodiment, the second upright plate 12 is arranged in a single row. In other embodiments, the second upright plate 12 may also be arranged in multiple rows, spaced apart along the axial direction of the pipe 40. This utility model does not limit this.
[0045] Furthermore, a reinforcing rib 14 is also connected between the extension section 22 and the upper support 10. Specifically, in this embodiment, the reinforcing rib 14 is disposed between the extension section 22 and the first upright plate 11. The number of reinforcing ribs 14 is set to multiple, and the multiple reinforcing ribs 14 are spaced apart along the axial direction of the pipe 40.
[0046] Furthermore, a stiffening rib 15 connects the vertical plate and the base plate 13. Specifically, in this embodiment, the stiffening rib 15 is disposed between the base plate 13 and the first vertical plate 11. In this embodiment, one stiffening rib 15 is disposed on each side of the vertical plate. Optionally, in other embodiments, multiple stiffening ribs 15 may be disposed on each side of the vertical plate. The multiple stiffening ribs 15 are spaced apart along the axial direction of the pipe 40.
[0047] Please refer to Figure 1 and Figure 2 Specifically, the lower support 30 includes a connecting plate 31 and a fixing seat 33. The fixing seat 33 is fixed to the hull. Specifically, the fixing seat 33 is welded to the hull. The connecting plate 31 is fixedly connected to the fixing seat 33. The connecting plate 31 is bolted to the base plate 13. A sliding washer 34 is disposed between the connecting plate 31 and the base plate 13. A waist hole 32 is formed on the connecting plate 31 or the base plate 13.
[0048] In this embodiment, the waist hole 32 is formed on the connecting plate 31. The base plate 13 has a circular hole corresponding to the waist hole 32. This enables a slidable connection between the base plate 13 and the connecting plate 31. When the pipe 40 expands due to heat, it causes the base plate 13 to slide relative to the connecting plate 31.
[0049] Optionally, in this embodiment, the extension direction of the waist hole 32 can be set as needed. Specifically, the waist hole 32 can be set along the axis of the pipe 40 or along a direction perpendicular to the axis of the pipe 40. The specific extension direction and length of the waist hole 32 can be determined according to the direction and size of the expansion of the pipe 40. As long as the slidable connection between the upper support 10 and the lower support 30 can be achieved, the present invention does not limit the specific structure of the waist hole 32.
[0050] The beneficial effects of the marine pipeline sliding support 100 provided in this embodiment of the utility model include:
[0051] The marine pipe sliding support 100 of this utility model includes a lower support 30 and an upper support 10. The lower support 30 is fixed to the hull. One end of the upper support 10 is connected to the lower support 30. The other end of the upper support 10 is used to fix the pipe 40. A slotted hole 32 is provided on the connecting surface of the upper support 10 and the lower support 30. A sliding washer 34 is provided between the upper support 10 and the lower support 30. By setting up the upper support 10 and the lower support 30, the upper support 10 fixes the pipe 40. By providing the slotted hole 32 on the connecting surface of the upper support 10 and the lower support 30, the upper support 10 and the lower support 30 can slide relative to each other. When the pipe 40 heats up and expands, it drives the upper support 10 to slide while maintaining the connection. By providing the sliding washer 34 between the upper support 10 and the lower support 30, wear caused by relative sliding between the upper support 10 and the lower support 30 is prevented. The marine pipe sliding support 100 of this utility model can adapt the support to the expansion of the pipe 40, prevent damage to the pipe 40, avoid wear of the support, and reduce material costs.
