Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of ship pipeline installation, and in particular to a ship pipeline fixing structure. Background Art

[0002] In ship products, fixed brackets are usually used to fix pipelines. After the brackets are welded, the fixed pipeline positions cannot be adjusted, resulting in many problems in the installation of pipelines. For example, due to the material properties, the weldability of the pressure hull of a ship is relatively poor. The same welding point is not allowed to be welded again, so the position of the pipeline cannot be adjusted by welding again; for brackets welded in the single hull area, after the outer side is laid with anechoic tiles, the high temperature generated by welding will cause serious damage to the anechoic tiles, because the environmental working temperature of the anechoic tiles is -30℃ to 65℃, and the cost of anechoic tiles is high, and the replacement cost is extremely high, so it is difficult to adjust the position of the pipeline by re-welding; for small spaces with compact layout, according to the ship construction process, the bracket is pre-welded with the hull structure. After the items around the bracket are installed, if the bracket position is adjusted again, it will be interfered by the surrounding items. In addition, in the above-mentioned cases, if the positioning of the bracket does not match the installation of the pipeline, since the welded bracket cannot be shifted and welded, the pipeline and bracket can only be positioned and matched by modifying the pipeline, and the process of modifying the pipeline is complicated, time-consuming and labor-intensive.

[0003] Therefore, it is necessary to propose a ship pipeline fixing structure to at least partially solve the problems in the prior art. Summary of the invention

[0034] In order to better understand the above-mentioned technical scheme, the technical scheme of the embodiments of the present application is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present application and the specific features in the embodiments are detailed descriptions of the technical scheme of the embodiments of the present application, rather than limitations on the technical scheme of the present application. In the absence of conflict, the embodiments of the present application and the technical features in the embodiments may be combined with each other.

[0035] like Figures 1 to 4 As shown, according to an embodiment of the present application, a ship pipeline 200 fixing structure is proposed, including: a bracket 110, used to be installed on a counterpart; a clamping ring 120, connected to the bracket 110 through a connecting rod, and the clamping ring 120 is used to clamp the pipeline 200; an adjustment assembly 140, used to adjust the relative positions of the clamping ring 120 and the bracket 110; wherein the counterpart includes the hull, ribs, inside and outside of the liquid tank of the ship.

[0036] In existing ship products, the bracket 110 and the clamp ring 120 are fixedly arranged, that is, the relative position between the clamp ring 120 and the bracket 110 cannot be adjusted. As a result, it is difficult to adjust the position of the clamp ring 120 again, and even the pipeline 200 needs to be modified again.

[0037] It is understandable that the fixed structure of the ship pipeline 200 provided in the embodiment of the present application is provided with a bracket 110, a connecting rod, a clamping ring 120 and an adjustment assembly 140. Among them, the bracket 110 can be installed on the opponent, and the connecting rod is connected to the top of the bracket 110 and extends upward. The clamping ring 120 can be connected to the bracket 110 through the connecting rod, and the pipeline 200 is clamped by the clamping ring 120. The relative position of the clamping ring 120 and the bracket 110 can be adjusted by the adjustment assembly 140, so as to be applicable to various usage scenarios of the ship, especially the scenario where the assembled bracket 110 cannot be modified. The clamping ring 120 can be precisely matched with the pipeline 200, avoiding the center deviation of the clamping ring 120 and the pipeline 200, improving the assembly reliability, and the structure is simple, practical, easy to install, and cost-saving.

[0038] It should be noted that, in the case where the above-mentioned counterpart is the pressure hull of a ship, since the material of the pressure hull is X80 steel, which has high strength, complex chemical composition and relatively poor weldability, preheating is required before welding to prevent welding cracks, and heat treatment is required after welding to improve the structure and performance of the welded joint and eliminate residual stress. Secondary welding is not allowed at the same welding point. Therefore, after the bracket 110 is welded to the pressure hull, the position of the clamping ring 120 can be adjusted by adjusting the relative position between the clamping ring 120 and the bracket 110 through the adjustment component 140 to ensure that the clamping ring 120 is stable in clamping the pipeline 200, and there is no need to remove and modify the position of the clamping ring 120 and then weld it again. In the case where the above-mentioned counterpart is the single hull area of ​​the ship, since the surface of the single hull is covered with anechoic tiles, the environmental working temperature of the anechoic tiles is -30°C to 65°C, and the high temperature generated by welding will cause serious damage to the anechoic tiles, resulting in inability to use them normally. The position of the clamp ring 120 can be adjusted by adjusting the relative position between the clamp ring 120 and the bracket 110 through the adjustment component 140, thereby avoiding damage to the sound-absorbing tile and saving costs. In the case where the above-mentioned opponent is a small space with a compact integrated layout of a ship, since the bracket 110 is pre-welded in the small space, if the bracket 110 needs to be disassembled to adjust the position, it will cause interference with surrounding items and be difficult to disassemble. The position of the clamp ring 120 can be adjusted by adjusting the relative position between the clamp ring 120 and the bracket 110 through the adjustment component 140, and the adjustment range is small, avoiding interference with surrounding items and improving reliability.

[0039] It should be noted that the bracket 110 installed on the pressure hull can be made of 923A steel, and the clamp ring 120 can be made of Q235B steel. The bracket 110 installed on the ribs of the ship, inside the liquid tank and outside the ship can be made of L907A steel, and the bracket 110 installed on the bulkhead, platform, raft and the outer surface of the internal liquid tank can be made of Q235B steel. The clamp ring 120 installed inside the liquid tank and outside the ship can be made of L907A steel.

[0040] In some examples, such as Figure 1 As shown, the adjustment assembly 140 includes: a first adjustment member 141, which is arranged on the connecting rod along the axial direction of the connecting rod, and is used to adjust the distance between the clamp ring 120 and the bracket 110 along the axial direction of the connecting rod; a second adjustment member, which is arranged on the bracket 110 along the radial direction of the connecting rod, and is used to adjust the relative positions of the clamp ring 120 and the bracket 110 along the radial direction of the connecting rod.

[0041] It is understandable that the adjustment assembly 140 may be provided with a first adjustment member 141 and a second adjustment member. Among them, the first adjustment member 141 may be arranged on the connecting rod along the axial direction of the connecting rod. In the axial direction of the connecting rod, the distance between the clamp ring 120 and the bracket 110 can be adjusted by the first adjustment member 141. The second adjustment member may be arranged on the bracket 110 along the radial direction of the connecting rod. In the radial direction of the connecting rod, the distance between the clamp ring 120 and the bracket 110 can be adjusted by the second adjustment member. In this way, the distance between the clamp ring 120 and the bracket 110 is adjusted by the first adjustment member 141 and the second adjustment member, so that the fixed structure of the ship pipeline 200 can be applied to a variety of usage scenarios of the ship, especially the scenario where the assembled bracket 110 cannot be modified. The clamp ring 120 can be precisely matched with the pipeline 200, the center deviation of the clamp ring 120 and the pipeline 200 is avoided, the assembly reliability is improved, and the structure is simple, practical, easy to install, and cost saving.

[0042] For example, the ship pipeline 200 fixing structure can be applied to the ship pipeline 200 system with low requirements for education, such as gas fire extinguishing system, sewage system, fresh water washing water system, fuel system and measuring instrument pipeline 200 system.

[0043] For example, a vibration isolation pad may be provided on the inner side of the clamp ring 120 . When the clamp ring 120 is clamped on the pipeline 200 , the vibration isolation pad is in contact with the pipeline 200 to isolate the pipeline 200 from vibration and improve reliability.

[0044] In some examples, such as Figure 1 As shown, the first adjusting member 141 includes: a first nut 1411, the connecting rod is a screw rod 130, one end of the screw rod 130 is passed through the bracket 110, and the first nut 1411 is screwed to the screw rod 130, and is respectively located on both sides of the bracket 110.

[0045] It is understandable that, in the case where the first adjusting member 141 is provided with a first nut 1411, the corresponding connecting rod may be a screw 130. Specifically, one end of the screw 130 may be inserted into the bracket 110 and arranged in the vertical direction. The first nut 1411 may be screwed on the screw 130, and at least two first nuts 1411 may be provided, and the two first nuts 1411 are respectively provided on both sides of the top plate of the bracket 110. The clamping ring 120 may be provided at one end of the screw 130 away from the bracket 110. By screwing the first nuts 1411 on both sides of the top plate of the bracket 110, the size of the screw 130 located above the bracket 110 may be adjusted, thereby adjusting the distance between the clamping ring 120 and the bracket 110 along the axial direction of the screw 130. The operation is simple, the structure is reliable, and the rotation of the thread is converted into the linear motion of the screw 130, so that the stroke distance can be accurately adjusted.

[0046] In some examples, such as Figure 1 As shown, the first adjusting member 141 further includes: a support plate 1412, which is passed through the end of the screw rod 130 away from the bracket 110, and the mounting edge of the clamp ring 120 is arranged at the end of the support plate 1412 away from the bracket 110; a second nut 1413, wherein one of the second nut 1413 is screwed on the end of the support plate 1412 facing the bracket 110, and the other second nut 1413 is screwed on the end of the mounting edge away from the support plate 1412.

[0047] It is understandable that the first adjusting member 141 may also be provided with a support plate 1412 and a second nut 1413. The support plate 1412 may be inserted through the top end of the screw rod 130, and the clamp ring 120 may be provided with an arc segment and a mounting edge, the arc segment is used to clamp the pipeline 200, and the mounting edge is used to connect to the support plate 1412. At least two second nuts 1413 may be provided, and one of the second nuts 1413 is provided at one end of the support plate 1412 facing the bracket 110, and the other second nut 1413 is provided at one end of the support plate 1412 away from the bracket 110. The support plate 1412 can be supported by the second nut 1413 provided at one end of the support plate 1412 facing the bracket 110. By screwing the first nuts 1411 on both sides of the top plate of the bracket 110, the size of the screw 130 above the bracket 110 can be adjusted, thereby adjusting the distance between the clamp ring 120 and the bracket 110 along the axis direction of the screw 130. The operation is simple, the structure is reliable, and the rotation of the thread is converted into a linear motion of the screw 130, so that the stroke distance can be accurately controlled. The clamp ring 120 is supported by the support plate 1412, and the support plate 1412 can support the pipeline 200, thereby improving reliability.

[0048] Exemplarily, two screw rods 130 may be provided, and they are axially symmetrically arranged with the center line of the top plate of the bracket 110 as the axis of symmetry. Correspondingly, the two screw rods 130 are passed through the support plate 1412, and the center line of the support plate 1412 coincides with the center line of the top plate of the bracket 110, and the support plate 1412 is parallel to the top plate of the bracket 110. Each screw rod 130 is respectively provided with two first nuts 1411 and two second nuts 1413 to ensure the force balance and stability.

[0049] Exemplarily, the screw rod 130 may use M8 threads, and the corresponding first nut 1411 and second nut 1413 may both use M8 threads.

[0050] In some examples, such as Figure 1 As shown, the length of the screw rod 130 is 55 mm to 100 mm.

[0051] It is understandable that if the length of the screw rod 130 is short, the distance adjustment dimension between the clamp ring 120 and the bracket 110 is small, and the adjustment effect is poor. If the length of the screw rod 130 is long, the structural strength of the screw rod 130 decreases, it is easy to bend, and it is not convenient to use in a small space and is easy to cause interference. Therefore, the size of the screw rod 130 is set to 55mm to 100mm.

[0052] In some examples, such as Figure 1 As shown, the first adjustment portion adjusts the distance between the support plate 1412 and the bracket 110 to be less than or equal to 45 mm.

[0053] It is understandable that the distance between the support plate 1412 and the bracket 110 in the axial direction of the screw rod 130 can be adjusted by the first adjusting member 141 and the second adjusting member, and the maximum adjustment distance is less than or equal to 45 mm.

[0054] In some examples, such as Figure 1 As shown, the fixing structure of the ship pipeline 200 further includes: a pad 150 , which is disposed at one end of the bracket 110 facing the clamp ring 120 , and the first nut 1411 is pressed against the pad 150 .

[0055] It is understandable that the fixed structure of the ship pipeline 200 may also be provided with a pad 150. Specifically, the pad 150 may be provided on the side of the top plate of the bracket 110 facing the support plate 1412. After the screw 130 is inserted into the top plate of the bracket 110, the first nut 1411 away from the support plate 1412 is screwed, and the first nut 1411 is tightened so that the first nut 1411 presses against the side of the bracket 110 away from the support plate 1412 to ensure that the screw 130 is fixed to the bracket 110. After the pad 150 is sleeved on the screw 130 and the pad 150 abuts against the side of the top plate of the bracket 110 facing the support plate 1412, the first nut 1411 close to the side of the support plate 1412 is screwed, and the first nut 1411 is tightened so that the first nut 1411 presses against the pad 150 to ensure that the pad 150 is fixed. The pad 150 improves the overall structural strength of the fixed structure and improves stability.

[0056] In some examples, such as Figure 1 As shown, the second adjusting member includes a waist-shaped hole, which is opened on the supporting surface of the bracket 110, and the connecting rod is passed through the waist-shaped hole.

[0057] It is understandable that the second adjusting member may use a waist-shaped hole 142. Specifically, the waist-shaped hole 142 may be opened on the top plate support surface of the bracket 110. And the connecting rod may be inserted into the waist-shaped hole 142. The length direction of the waist-shaped hole 142 is consistent with the length direction of the top plate of the bracket 110. By adjusting the position of the connecting rod in the waist-shaped hole 142, the radial distance between the clamp ring 120 and the bracket 110 along the connecting rod can be adjusted. Through the cooperation of the first adjusting member 141 and the second adjusting member, the clamp ring 120 can be accurately matched with the pipeline 200, avoiding the center deviation of the clamp ring 120 and the pipeline 200, improving the assembly reliability, and having a simple structure, strong practicality, easy installation, and cost saving.

[0058] For example, two waist-shaped holes 142 may be provided, which are symmetrically arranged with the center line of the top plate of the bracket 110 as the symmetry axis, and two corresponding screw rods 130 may be provided, which are respectively inserted into the waist-shaped holes 142. The outer diameter of the first nut 1411 is larger than the diameter of the waist-shaped hole 142 to ensure that the first nut 1411 can be pressed against the bracket 110.

[0059] In some examples, such as Figure 1 As shown, the adjustment distance of the above-mentioned connecting rod in the above-mentioned waist-shaped hole is less than or equal to 20 mm.

[0060] It is understandable that the adjustable distance of the connecting rod in the waist-shaped hole 142 along the length direction of the waist-shaped hole 142 does not exceed 20 mm, so as to avoid the waist-shaped hole 142 being set too large and reducing the structural strength of the bracket 110.

[0061] In some examples, a surface of at least one of the first nut 1411 , the second nut 1413 , and the screw rod 130 is provided with an anti-rust composite coating.

[0062] It is understandable that the surfaces of the first nut 1411, the second nut 1413 and the screw 130 may be coated with an anti-rust composite coating to prevent the above-mentioned parts from rusting in the humid operating environment of the ship, thereby improving the protection effect of the parts, extending the service life of the parts and improving reliability.
