Abstract
Description
Technical Field
[0001] This invention relates to the field of shipbuilding technology, and in particular to a tooling and method for installing an integral stern tube for ships. Background Technology
[0002] Large ships typically use epoxy supports to fix the integral stern tube to the hull structure. This involves inserting the integral stern tube, pre-assembled with fore and aft bearings, into the hull structure, and then pouring epoxy resin into the gap between the integral stern tube and the hull structure. After the epoxy resin cures at room temperature, it forms an integrated support layer, thus permanently fixing the integral stern tube to the hull structure.
[0003] During epoxy casting, the entire tail tube is usually fixed by supporting the ends. However, in the actual epoxy casting process, the curing of epoxy generates a lot of heat, causing the tail tube to expand laterally. This leads to bearing deformation, resulting in a significant deviation in the ellipticity or slope of the bearing compared to before installation. In some cases, the bearing may even need to be re-machined, causing serious delays and economic losses. Summary of the Invention
[0004] Therefore, it is necessary to provide a tooling and method for installing integral stern tubes for ships, addressing the problem of bearing deformation caused by thermal expansion of the stern tube during epoxy casting.
[0005] On one hand, this application provides a tooling for installing an integral stern tube for ships, used to support the bearing of the integral stern tube during epoxy casting. The tooling includes: a pair of adjustable support assemblies, each comprising an annular bracket, a plurality of radial supports, and a plurality of axial supports. The annular bracket is disposed at one end of the integral stern tube. The plurality of radial supports are adjustablely disposed on the two annular brackets in the radial direction to support the bearing radially. The plurality of axial supports are adjustablely disposed on the two annular brackets in the axial direction to support the bearing axially. The tooling also includes a plurality of elastic buffer elements, each of which is fixed to one of the axial supports of the adjustable support assembly and abuts against the bearing.
[0006] In one embodiment, the annular bracket includes an annular radial support plate and a plurality of axial support plates fixed to the radial support plate. The axial support plates are spaced apart around the axis of the radial support plate and extend into the radial support plate along the radial direction of the radial support plate. The axial support members are respectively disposed on the axial support plates.
[0007] In one embodiment, the radial support plate has a plurality of radial threaded holes on its side, and the radial support member is a radial support bolt, which is screwed into the radial threaded holes; the axial support plate has axial threaded holes, and the axial support member is an axial support bolt, which is screwed into the axial threaded holes.
[0008] In one embodiment, the elastic buffer element is larger than the outer diameter of the axial support.
[0009] In one embodiment, the integral stern tube mounting fixture for ships further includes a gasket, which is fixed between the elastic buffer element and the axial support, and the outer diameter of the gasket is larger than the outer diameter of the axial support.
[0010] In one embodiment, the elastic cushioning element is a rubber block.
[0011] In one embodiment, the integral stern tube mounting fixture for ships further includes multiple inner wall support assemblies, each inner wall support assembly including a support rod and arc plates respectively fixed at both ends of the support rod, the arc plates being used to abut against the inner wall of the bearing.
[0012] In one embodiment, the support rod includes a connector, two sub-rods, and two locking members. One end of each of the two sub-rods is adjustablely connected to both ends of the connector. The two arc plates are fixed to the other ends of the two sub-rods. The two locking members are respectively disposed at the connection between the sub-rods and the connector to lock the relative position of the sub-rods and the connector.
[0013] In one embodiment, the connector includes a connecting portion and connecting sleeves connected to both sides of the connecting portion. The inner wall of the connecting sleeve is provided with an internal thread, and one end of the sub-rod is provided with an external thread. The external threads of the two sub-rods are respectively screwed into the internal threads of the two connecting sleeves. The locking component is a locking nut, which is screwed into the two sub-rods respectively.
[0014] In one embodiment, the connecting part is an annular structure, and the two connecting sleeves are symmetrically connected to both sides of the connecting part.
[0015] On the other hand, this application also provides a method for installing an integral tailpipe, including the following steps: Adjustable support assemblies are installed at both ends of the integral tailpipe to support the bearings of the integral tailpipe. An elastic buffer element is provided between one of the adjustable support components and the bearing; First, epoxy resin is poured into the area where the bearing without the elastic buffer element is located. After cooling and curing, epoxy resin is poured into the area where the bearing with the elastic buffer element is located. After cooling and solidification, remove the adjustable support assembly and the elastic buffer element.
[0016] In one embodiment, the step of installing adjustable support assemblies at both ends of the integral tailpipe, so that the adjustable support assemblies support the bearings of the integral tailpipe, includes: Adjust the radial support members of the adjustable support assembly so that the radial support assembly abuts against the bearing radially, and align the axis of the annular bracket of the adjustable support assembly with the axis of the bearing. Adjust the axial support members of the adjustable support assembly so that the axial support members abut against the bearing along the axial direction.
[0017] In one embodiment, after the step of providing an elastic cushioning element between one of the adjustable support components and the bearing, the step further includes: An inner wall support assembly is installed inside the integral tailpipe, such that the arc plate of the inner wall support assembly abuts against the inner wall of the bearing.
[0018] The integral tooling for ships described in this application features adjustable support components at both ends of the integral stern tube. The radial support components provide adjustable support for the bearing in the radial direction, ensuring that the axis of the annular bracket coincides with the axis of the integral stern tube. This guarantees that the installation position accuracy of the integral stern tube meets design requirements and provides an accurate positioning reference for subsequent epoxy casting. Simultaneously, the adjustable support components support the bearing in the axial direction, and an elastic buffer element is placed between the axial support and the bearing. This elastic buffer element absorbs the axial deformation of the integral stern tube caused by thermal expansion during epoxy casting. Compared to traditional rigid fixing methods, this avoids bending deformation of the integral stern tube, effectively preventing deviations in the ellipticity and slope of the bearing and reducing the risk of bearing reprocessing.

[0027] Addressing the problem of bearing deformation caused by thermal expansion of the stern tube during epoxy casting in existing marine integral stern tube systems, this application provides a marine integral stern tube installation fixture and a method for installing the integral stern tube. This marine integral stern tube installation fixture is used to support the bearings of the integral stern tube during epoxy casting.
[0028] Specifically, such as Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the installation fixture for the integral stern tube 50 of the ship may include a pair of adjustable support assemblies 10 and a plurality of elastic buffer elements 20. Each adjustable support assembly 10 includes an annular bracket 11, a plurality of radial supports 12, and a plurality of axial supports 13. The annular bracket 11 is disposed at one end of the integral stern tube 50. The plurality of radial supports 12 are respectively adjustablely disposed on the two annular brackets 11 in the radial direction to support the bearing 51 in the radial direction. The plurality of axial supports 13 are respectively adjustablely disposed on the two annular brackets 11 in the axial direction to support the bearing 51 in the axial direction. The plurality of elastic buffer elements 20 are respectively fixed to each of the axial supports 13 of one of the adjustable support assemblies 10 to abut against the bearing 51.
[0029] It is understood that the integral tooling for ships in this application, by setting adjustable support components 10 at both ends of the integral stern tube 50, and using radial support components to provide adjustable support for the bearing 51 in the radial direction, enables the axis of the annular bracket 11 to coincide with the axis of the integral stern tube 50, ensuring that the installation position accuracy of the integral stern tube 50 meets the design requirements and providing an accurate positioning reference for subsequent epoxy casting. At the same time, the adjustable support components 10 support the bearing 51 in the axial direction, and an elastic buffer element 20 is set between the axial support 13 and the bearing 51. The elastic buffer element 20 can absorb the axial deformation of the integral stern tube 50 caused by thermal expansion during epoxy casting. Compared with the traditional rigid fixing method, this can avoid bending deformation of the integral stern tube 50, thereby effectively preventing deviations in the ellipticity and slope of the bearing 51 and reducing the risk of reprocessing the bearing 51.
[0030] Optionally, such as Figure 1As shown, in some embodiments, the annular support 11 may include a radial support plate 111 and multiple axial support plates 112. The radial support plate 111 is annular, and the axial support plates 112 can be fixed to the radial support plate 111 by welding, screwing, or other means. The axial support plates 112 are arranged at intervals around the axial direction of the radial support plate 111 and extend into the radial support plate 111 along its radial direction. Axial support members 13 are respectively disposed on the axial support plates 112. In this way, after the radial support plate 111 and the axial support plates 112 are combined, the normal of the axial support plate 112 and the normal of the radial support plate 111 are perpendicular to each other, thereby ensuring that the direction of the axial support force is perpendicular to the direction of the radial support force, avoiding the oblique component force generated by the non-perpendicularity of the axial and radial support forces, and preventing the bearing 51 from torsion or skewed deformation due to the deviation of the force direction during epoxy casting.
[0031] Optionally, in some embodiments, the radial support plate 111 has multiple radial threaded holes on its side, and the radial support member 12 is a radial support bolt, which is screwed into the radial threaded hole; the axial support plate 112 has axial threaded holes, and the axial support member 13 is an axial support bolt, which is screwed into the axial threaded hole. Thus, the radial support member 12 and the radial support plate 111, and the axial support member 13 and the axial support plate 112 are all adjustablely connected using bolts and threaded holes. By rotating the radial and axial support bolts, their positions can be adjusted, making the support positions of the radial support member 12 and the axial support member 13 more precise and convenient. Workers can fine-tune each radial support member 12 or axial support member 13 according to the actual installation accuracy requirements. Furthermore, the threaded fit has a self-locking characteristic, making it less prone to loosening after adjustment, thus improving the reliability and stability of the overall tailpipe 50 epoxy casting.
[0032] It is worth noting that before epoxy casting, the axial support bolts on the side with the elastic buffer element 20 are slightly tightened to keep the elastic buffer element 20 in its natural state, ensuring that the elastic buffer element 20 can absorb thermal expansion.
[0033] Optionally, such as Figure 7 As shown, in some embodiments, the elastic buffer element 20 is larger than the outer diameter of the axial support 13. By increasing the contact area between the elastic buffer element 20 and the bearing 51, sufficient support area can be ensured between the elastic buffer element 20 and the bearing 51. In this way, during the epoxy casting process, the elastic buffer element 20 can more comprehensively absorb the axial thermal expansion of the tailpipe.
[0034] Optionally, such as Figure 7As shown, in some embodiments, the integral stern tube 50 mounting fixture for ships also includes a gasket 30. The gasket 30 can be fixed between the elastic buffer element 20 and the axial support 13 by welding or other means. The outer diameter of the gasket 30 is larger than the outer diameter of the axial support 13. The gasket 30 can increase the force-bearing area between the elastic buffer element 20 and the axial support 13, so that the elastic buffer element 20 can fully utilize its entire end face to participate in compression deformation when under pressure, avoiding only the central area of the elastic buffer element 20 being compressed, resulting in the edge areas not being effective, and ensuring that the elastic buffer element 20 produces uniform compression deformation when under pressure. In this way, during the epoxy casting process, the stern tube expands longitudinally due to heat and axially compresses the elastic buffer element 20. The gasket 30 evenly distributes the axial support force provided by the axial support 13 to the entire elastic buffer element 20, so that the elastic buffer element 20 can continuously and stably absorb the axial thermal expansion of the stern tube, preventing local deformation of the stern tube caused by uneven thermal expansion absorption.
[0035] Optionally, in some embodiments, the elastic buffer element 20 is a rubber block, which can be directly bonded to the gasket 30 with adhesive. Utilizing the excellent elastic deformation capacity, compression resistance, and heat resistance of rubber material, it can effectively absorb the axial thermal expansion displacement generated during epoxy casting. Furthermore, the rubber block is inexpensive, easy to replace, and suitable for various application scenarios. The rubber block can be directly bonded to the gasket 30 with adhesive.
[0036] Furthermore, such as Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 8 As shown, in some embodiments, the installation fixture for the integral stern tube 50 of a ship may further include multiple inner wall support assemblies 40. Each inner wall support assembly 40 includes a support rod 41 and arcuate plates 42 respectively fixed to both ends of the support rod 41. The arcuate plates 42 are used to abut against the inner wall of the bearing 51. This inner wall support assembly 40 can provide radial support force to the bearing 51 from the inside during the epoxy casting process, and cooperates internally and externally with the adjustable support assembly 10 to effectively prevent the bearing 51 from deforming in perpendicularity due to the thermal expansion of the stern tube.
[0037] Optionally, such as Figure 2As shown, in some embodiments, the support rod 41 may include a connector 411, two sub-rods 412, and two locking members 413. One end of each of the two sub-rods 412 is adjustablely connected to both ends of the connector 411. Two arc plates 42 are fixed to the other ends of the two sub-rods 412. The two locking members 413 are respectively disposed at the connection between the sub-rods 412 and the connector 411 to lock the relative positions of the sub-rods 412 and the connector 411. In this way, by adjusting the connection position between the sub-rods 412 and the connector 411, and locking the adjusted position with the locking members 413, the total length of the support rod 41 can be flexibly adjusted, allowing the inner wall support assembly 40 to adapt to the bearings 51 of the integral tailpipe 50 of different specifications and sizes, thus improving the versatility and adaptability of the inner wall support assembly 40.
[0038] Optionally, such as Figure 3 As shown, in some embodiments, the connector 411 includes a connecting portion 4111 and connecting sleeves 4112 connected to both sides of the connecting portion 4111. The inner wall of the connecting sleeve 4112 is provided with internal threads, and one end of the sub-rod 412 is provided with external threads. The external threads of the two sub-rods 412 are respectively screwed into the internal threads of the two connecting sleeves 4112. The locking member 413 is a locking nut, which is screwed into the two sub-rods 412 respectively. In this way, when the two sub-rods 412 are simultaneously screwed out of the connecting sleeve 4112, the total length of the support rod 41 increases, and the distance between the two arc plates 42 increases. When the two sub-rods 412 are simultaneously screwed in into the connecting sleeve 4112, the total length of the support rod 41 shortens, and the distance between the two arc plates 42 decreases. Once the adjustment is complete, tighten the locking nut along the sub-rod 412 and abut it against the end face of the connecting sleeve 4112. Use the friction between the threaded pairs to lock the relative position of the sub-rod 412 and the connecting sleeve 4112, preventing changes in length due to vibration or force during use.
[0039] Optionally, such as Figure 3 As shown, in some embodiments, the connecting part 4111 has an annular structure, and two connecting sleeves 4112 are symmetrically connected to both sides of the connecting part 4111. Thus, when the inner wall support assembly 40 is installed inside the integral tail tube 50, the axis of the connecting part 4111 can be aligned and coincident with the axis of the integral tail tube 50. The two connecting sleeves 4112 are symmetrically located on both sides of the connecting part 4111, so that the two arc plates 42 connected to the connecting sleeves 4112 via the sub-rod 412 are also symmetrically located on both sides of the connecting part 4111. During epoxy casting, the bearing 51 is subjected to thermal expansion and compression from the integral tail tube 50. The symmetrically arranged arc plates 42 can simultaneously abut against the inner wall of the bearing 51 from the inside, constraining the radial deformation of the bearing 51, thereby effectively suppressing the vertical deformation of the bearing 51.
[0040] Furthermore, such as Figure 9 As shown, this application also provides a method for installing an integral stern tube, which installs the integral stern tube using any of the aforementioned marine integral stern tube installation fixtures. The method may include the following steps: S100. Adjustable support components are installed at both ends of the integral tailpipe, so that the adjustable support components support the bearings of the integral tailpipe. S200, An elastic buffer element is provided between one of the adjustable support components and the bearing; S300. First, epoxy resin is poured into the area where the bearing is located without the elastic buffer element. After cooling and curing, epoxy resin is poured into the area where the bearing is located with the elastic buffer element. S400. After cooling and curing, remove the adjustable support assembly and the elastic buffer element.
[0041] Understandably, referring to the above-described installation method for the integral tailpipe 50, adjustable support components 10 are installed near the bearings 51 at both ends of the integral tailpipe 50 to provide stable support for the bearings 51 in both radial and axial directions. An elastic buffer element 20 is placed between one of the adjustable support components 10 and the bearing 51. During epoxy casting, epoxy is first cast onto the area where the bearing 51 is located on the side without the elastic buffer element 20, so that the thermal expansion stress generated during the epoxy curing process on that side can be fully released to the side with the elastic buffer element 20. After that side cools and cures, epoxy is then cast onto the area where the bearing 51 is located on the side with the elastic buffer element 20. At this time, the elastic buffer element 20 can effectively absorb the axial thermal expansion generated during the epoxy curing on that side. In this way, by setting the elastic buffer element 20 and performing epoxy casting on both sides of the integral tailpipe 50 in stages, the problem of bearing 51 deformation caused by the thermal expansion of the integral tailpipe 50 during epoxy casting can be solved, ensuring the ellipticity and slope accuracy of the bearing 51, avoiding the need for reprocessing of the bearing 51, and reducing production costs.
[0042] Optionally, such as Figure 10 As shown, in some embodiments, step S100, which involves installing adjustable support assemblies at both ends of the integral tailpipe to support the bearing of the integral tailpipe, includes: S110. Adjust the radial support members of the adjustable support assembly so that the radial support assembly abuts against the bearing radially and the axis of the annular bracket of the adjustable support assembly is aligned with the axis of the bearing. S120. Adjust the axial support of the adjustable support assembly so that the axial support abuts against the bearing along the axial direction.
[0043] Referring to the above steps, when installing the adjustable support assembly 10, the radial support 12 and the axial support 13 can be adjusted respectively to make the axis of the annular bracket 11 precisely aligned with the axis of the bearing 51, and the axial support 13 tightly abut against the end of the bearing 51, ensuring that the installation position accuracy of the overall tailpipe 50 meets the design requirements, and providing an accurate positioning reference for subsequent epoxy casting.
[0044] Optionally, such as Figure 11 As shown, in some embodiments, after step S200, the step of providing an elastic buffer element between one of the adjustable support components and the bearing, the method further includes the step of: S210. Install an inner wall support assembly inside the integral tailpipe, such that the arc plate of the inner wall support assembly abuts against the inner wall of the bearing.
[0045] Following the steps described above, an inner wall support assembly 40 is installed inside the integral tailpipe 50, with the arc plate 42 of the inner wall support assembly 40 abutting against the inner wall of the bearing 51. This provides additional radial support force to the bearing 51 from the inside during the epoxy casting process, reducing the vertical deformation of the bearing 51.
[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0047] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
