Description

Technical Field

[0001] The utility model belongs to the technical field of hull structures, and in particular relates to a hull structure and a ship. Background Art

[0002] The general hull includes a structural frame and a stern shaft frame. To reduce the weight of the hull, the structural frame is generally made of aluminum alloy, while to ensure the strength of the stern shaft, the stern shaft frame is generally made of stainless steel. Since the stainless steel stern shaft frame cannot be welded with the aluminum alloy structural frame, the stern shaft frame is generally fixed to the structural frame by bolts.

[0003] However, in order to ensure that the stern shaft bracket is aligned with the axis centerline of the stern shaft after being fixed, it is often necessary to grind the mounting surface connected to the stern shaft bracket in the structural frame before installing the stern shaft bracket, and determine whether the stern shaft bracket is aligned with the axis centerline of the stern shaft by installing the stern shaft bracket multiple times. If not, it is necessary to disassemble the stern shaft bracket and grind the mounting surface again. Such repeated grinding leads to a generally long hull manufacturing cycle and a surge in costs.

[0004] Therefore, the existing technology needs to be improved and developed. Utility Model Content

[0005] The utility model aims to provide a hull structure and a ship, which solves the problem of repeatedly grinding the structure frame when installing the stern shaft frame, thereby achieving the effect of shortening the hull manufacturing cycle and reducing costs.

[0008] The hull structure provided by the utility model adopts epoxy resin to avoid direct contact between the mounting surfaces of the stern shaft frame and the structure frame, thereby eliminating the grinding process for the mounting surface, greatly shortening the manufacturing cycle and effectively reducing the manufacturing cost.

[0009] Furthermore, the first cavity includes a fixing plate, the fixing plate and the first end are separated by the connecting portion, and the fixing plate is fixedly connected to the first end via the connecting portion.

[0010] The connecting portion is indirectly connected to the fixing plate, which means that the mounting surface of the fixing plate no longer needs to be kept flat, and therefore there is no need to polish the mounting surface, thereby improving the hull manufacturing efficiency and shortening the hull manufacturing cycle.

[0011] Furthermore, a reinforcing rib is provided on a side of the fixing plate facing away from the first end.

[0012] The reinforcing ribs can increase the strength of the fixing plate, thereby helping to improve the quality of the hull.

[0013] Furthermore, the fixing plate is fixedly connected to the first end via bolts.

[0014] Furthermore, the bolt is made of stainless steel.

[0015] Furthermore, the structural frame is made of aluminum alloy material.

[0016] Furthermore, the fixing plate is made of aluminum alloy material.

[0017] Furthermore, the stern shaft frame is made of stainless steel.

In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and / or the use of other materials.

[0038] Reference Figure 1 and attached Figure 2 The utility model provides a hull structure, including a structural frame 100, the structural frame 100 is provided with a first cavity 110, and a connecting portion 200 formed by filling epoxy resin is provided in the first cavity 110;

[0039] The hull structure also includes a stern shaft frame 300, which includes a bracket 310 and a hub 320. The bracket 310 includes a second end 312 and a first end 311 with a T-shaped cross-section. The second end 312 is fixedly connected to the hub 320; the first end 311 is located in the first cavity 110 and is completely wrapped by the connecting part 200, and the first end 311 is fastened to the structural frame 100 through the connecting part.

[0040] In this embodiment, in actual application, after adjusting the position of the stern shaft frame 300 in the first cavity 110 and ensuring that the stern shaft frame 300 is aligned with the axial centerline of the stern shaft, epoxy resin is poured into the first cavity 110 and waited for it to solidify. After the epoxy resin is solidified, the position of the stern shaft frame 300 is fixed. Since the epoxy material has the characteristics of low viscosity and small surface tension, the connecting portion 200 formed by it can adapt to any irregular surface. The stern shaft frame 300 is not in direct contact with the installation surface of the structural frame 100, but is indirectly connected to the structural frame 100 through the connecting portion 200, which makes it unnecessary for the user to grind the installation surface of the structural frame 100, eliminating the grinding process, thereby shortening the hull manufacturing cycle and reducing costs.

[0041] Furthermore, since the first end 311 is located in the first cavity 110 and is completely wrapped by the connecting portion 200, setting the first end 311 in a T shape can increase the contact area between the stern shaft frame 300 and the connecting portion 200, thereby improving the fixing force of the stern shaft frame 300, which is beneficial to ensuring the quality of the hull.

[0042] In certain embodiments, referring to Figure 1 and attached Figure 2The first cavity 110 includes a fixing plate 120 , the fixing plate 120 and the first end 311 are separated by a connecting portion 200 , and the fixing plate 120 is fixedly connected to the first end 311 through the connecting portion 200 .

[0043] In the traditional installation method of the stern shaft frame 300, the stern shaft frame 300 is in direct contact with the fixing plate 120 and fixed on the fixing plate 120. At this time, the installation surface where the fixing plate 120 contacts the stern shaft frame 300 is required to be kept flat, otherwise the stern shaft frame 300 will not be able to align with the center line of the stern shaft. Therefore, the traditional method often requires careful polishing of the installation surface of the fixing plate 120 and repeated installation and debugging of the stern shaft frame 300, resulting in a generally longer hull manufacturing cycle and a surge in costs.

[0044] In this embodiment, the stern shaft frame 300 is not in direct contact with the fixing plate 120 but is indirectly connected to the fixing plate 120 through the connecting portion 200, which makes it unnecessary to keep the mounting surface of the fixing plate 120 flat, and therefore does not need to be polished, thereby improving the hull manufacturing efficiency and shortening the hull manufacturing cycle. When the epoxy resin is poured into the first cavity 110, the epoxy resin flows and automatically fills the pits on the mounting surface of the fixing plate 120, so that the solidified connecting portion 200 is well adapted to the mounting surface of the fixing plate 120, thereby ensuring that the stern shaft frame 300 is aligned with the axial centerline of the stern shaft and is firmly fixed.

[0045] In certain embodiments, referring to Figure 1 and attached Figure 2 A reinforcing rib 130 is provided on one side of the fixing plate 120 facing away from the first end 311. The reinforcing rib 130 can increase the strength of the fixing plate 120, thereby facilitating improving the quality of the hull.

[0046] In some embodiments, the fixing plate 120 is fixedly connected to the first end 311 by bolts (not shown), and the bolts are used to strengthen the fixing force of the stern shaft frame 300, further ensuring the installation strength of the stern shaft frame 300, thereby ensuring the quality of the hull.

[0047] In certain embodiments, the bolt is made of a stainless steel material.

[0048] In certain embodiments, the structural frame 100 is made of aluminum alloy material.

[0049] In some embodiments, the fixing plate 120 is made of an aluminum alloy material.

[0050] In certain embodiments, the stern bracket 300 is made of a stainless steel material.

[0051] In certain embodiments, referring to Figure 2The bottom of the first cavity 110 is provided with an opening 140 communicating with the outside, and the opening 140 is used for the user to place the stern shaft frame 300 into the first cavity 110. When installing the stern shaft frame 300, the opening 140 should be closed with a mold frame to seal the first cavity 110, and then epoxy resin is poured into the first cavity 110 (an injection port is reserved on the mold frame). After the epoxy resin is cured to form the connecting portion 200, the mold frame is removed.

[0052] In certain embodiments, referring to Figure 3 The first end 311 is provided with a plurality of reinforcement grooves 400, which can further increase the contact area between the stern shaft frame 300 and the connecting portion 200. Specifically, when the epoxy resin is poured, the epoxy resin flows and automatically fills the reinforcement grooves 400. After the epoxy resin is cured, the epoxy resin in the reinforcement grooves 400 will further improve the fixing force of the stern shaft frame 300.

[0053] For further information, see Attachment Figure 3 The reinforcement groove 400 is inclined, and the inclined reinforcement groove 400 can prevent the epoxy resin cured in the reinforcement groove 400 from easily falling out of the reinforcement groove 400, thereby facilitating the fixing effect of the stern shaft frame 300.

[0054] For further information, see Attachment Figure 3 and attached Figure 4 The reinforcement groove 400 passes through the first end 311 along its own extension direction; a detachable insert block 500 is provided at the bottom of the reinforcement groove 400, and the insert block 500 is slidably arranged in the reinforcement groove 400 and can reciprocate along the extension direction of the reinforcement groove 400.

[0055] In this embodiment, when the user wants to remove the stern shaft frame 300 after fixing the stern shaft frame 300 with the connecting portion 200, in order to facilitate the user to remove the cured epoxy resin in the reinforcement groove 400, a movable insert 500 is provided in the reinforcement groove 400. For details, refer to the attached Figure 5 , Attachment Figure 6 , Attachment Figure 7 and attached Figure 8When the reinforcing groove 400 is not yet filled with cured epoxy resin, the insert 500 is in interference fit with the reinforcing groove 400. The user can drive the insert 500 to move by knocking the insert 500 from the end surface of the insert 500 along the extension direction of the reinforcing groove 400, thereby realizing the installation and removal of the insert 500. After the reinforcing groove 400 is filled with cured epoxy resin, the epoxy resin is adhered to the insert 500. The user needs to knock the insert 500 harder and force the insert 500 to come out of the first end 311, thereby destroying the insert 500 and The connection of the cured epoxy resin, at this time, a second cavity 410 is formed at the bottom of the cured epoxy resin in the reinforcement groove 400, and thereafter the user repeatedly inserts the blade into the gap between the side walls of the reinforcement groove 400 to destroy the connection between the reinforcement groove 400 and the cured epoxy resin. Finally, the cured epoxy resin is no longer adhered to the reinforcement groove 400, and the entire cured epoxy resin hidden in the reinforcement groove 400 can be ejected from the end face of the cured epoxy resin along the extension direction of the reinforcement groove 400, thereby achieving the effect of easily removing the cured epoxy resin in the reinforcement groove 400.

[0056] Furthermore, when the cured epoxy resin is no longer adhered to the reinforcement groove 400, the user may also choose to insert a rod of a suitable size into the second cavity 410 and then push the cured epoxy resin in the reinforcement groove 400 out of the reinforcement groove 400 from one side of the second cavity 410. This method can also quickly and conveniently remove the cured epoxy resin in the reinforcement groove 400.

[0057] It should be noted that after the cured epoxy resin in the reinforcement groove 400 is removed, the insert 500 can be reinserted into the reinforcement groove 400, so that it can be used repeatedly.

[0058] The utility model provides a ship, comprising the hull structure in the above embodiment.

[0059] In the description of this specification, the description with reference to the terms "one embodiment", "certain embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiments or examples are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.
