Description

Technical Field

[0001] This utility model relates to the field of shipbuilding technology, and in particular to a connection structure for connecting a ship's stern shaft and intermediate shaft or short shaft. Background Technology

[0002] Ships are a general term for all kinds of vessels. They are means of transportation that can navigate or anchor in waterways for transport or operations. Ships have different technical performance, equipment and structural types according to different usage requirements. The stern shaft of a ship is usually mounted on two key bearings: the stern bearing, which is the end in contact with the water, and the forward bearing, which is connected to the engine room. Between these two is the enclosed stern shaft compartment. Together, they support the weight of the ship and the pressure of the water, ensuring the stability of the ship.

[0003] In actual use, fasteners are usually used to install and fix the stern shaft and intermediate shaft or short shaft of existing ships. However, the stern shaft and intermediate shaft or short shaft are immersed in water for a long time. As a result, the surface of the fasteners will be corroded by the water. The fasteners will be unusable after disassembly, and in severe cases, it will be difficult to disassemble the fasteners. Utility Model Content

[0004] The purpose of this utility model is to provide a connection structure for connecting the stern shaft and intermediate shaft or short shaft of a ship, in order to solve the problem mentioned in the background art above. In actual use, the stern shaft and intermediate shaft or short shaft of a ship are usually installed and fixed with fasteners. However, the stern shaft and intermediate shaft or short shaft are immersed in water for a long time. As a result, the surface of the fasteners will be corroded by the water. The fasteners will be unusable after disassembly, and in severe cases, it will be difficult to disassemble the fasteners.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a connection structure for connecting a ship's stern shaft and intermediate shaft or short shaft, comprising:

[0007] The body component includes a tail shaft housing and a short shaft housing;

[0008] The protective component includes a first anti-corrosion ring, a second anti-corrosion ring, a fixing block, a mounting plate, and a fixing slot;

[0009] The outer ends of both the tail shaft housing and the short shaft housing are connected to the mounting plate. The first anti-corrosion ring and the second anti-corrosion ring surround the outer surface of the mounting plate. One end of the first anti-corrosion ring has a symmetrically opened fixing slot, and one end of the second anti-corrosion ring is symmetrically connected to a fixing block. The fixing block is connected to the inside of the fixing slot by insertion.

[0010] Furthermore, the fixing block and fixing slot are irregularly shaped, and the first anti-corrosion ring and the second anti-corrosion ring are in a corresponding form.

[0011] Furthermore, it also includes reinforcing components, which include a fixing block, a sliding groove, a fixing hole, a fixing rod, a fixing frame, and a fixing rod;

[0012] A set of fixing blocks are symmetrically connected to the outer surfaces of the tail shaft housing and the short shaft housing. The fixing blocks have grooves inside. Slider blocks are connected to both sides of the fixing frame. The sliders are movably connected inside the grooves. The fixing frame is clamped between the first anti-corrosion ring and the second anti-corrosion ring.

[0013] Furthermore, a fixing hole is formed in the middle of the top of the fixing block, and a fixing rod is connected to the middle of the top of the slider. The fixing rod is connected to the inside of the fixing hole by insertion.

[0014] Furthermore, it also includes fixing components, which include a reinforcing ring, a protective ring, a sealing gasket, a compression ring, a limiting ring, a pull rod, and a spring;

[0015] The other end of the outer surface of the tail shaft housing is connected to a protective ring. A sealing gasket is bonded to the inner wall of the protective ring. A reinforcing ring surrounds the outer surface of the sealing gasket. A compression ring is installed inside the reinforcing ring. A limiting ring is connected to one side of the compression ring. Springs are evenly connected to the top of the compression ring. Pull rods are connected to both ends of the compression ring. The pull rods pass through the reinforcing ring.

[0016] Furthermore, the compression ring is fitted to the outer surface of the sealing gasket, while the limiting ring is connected to one side of the sealing gasket.

[0017] Compared with existing technologies, the advantages of this utility model are:

[0018] This invention features a first and a second anti-corrosion ring, both containing anti-corrosion materials. After the tail shaft housing and short shaft housing are installed, the fixing block is inserted into the fixing slot, completely surrounding the outer surface of the mounting plate. This prevents water from contacting the mounting plate after the tail shaft housing and short shaft housing are immersed, facilitating the disassembly of the mounting plate and fasteners for continued use.

[0019] Based on the aforementioned intended effects, by incorporating a reinforcing ring and a compression ring, the tail shaft housing itself possesses a sealing structure during installation. After the gasket is installed, the compression ring is pressed against the top of the gasket by a spring, while the limiting ring blocks one side of the gasket. The compression of the compression ring can prevent gaps from forming in the gasket after prolonged use, while the limiting ring can prevent deformation of the gasket after prolonged use, thus improving sealing performance.

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0032] Please see Figure 1 , Figure 2 As shown, this embodiment is a connection structure for connecting a ship's stern shaft and intermediate shaft or short shaft, including:

[0033] The main body component includes a tail shaft housing 11 and a short shaft housing 12;

[0034] The protective component includes a first anti-corrosion ring 21, a second anti-corrosion ring 22, a fixing block 23, a mounting plate 24, and a fixing slot 25.

[0035] The outer ends of the tail shaft housing 11 and the short shaft housing 12 are both connected to the mounting plate 24. The first anti-corrosion ring 21 and the second anti-corrosion ring 22 surround the outer surface of the mounting plate 24. One end of the first anti-corrosion ring 21 is symmetrically provided with a fixing slot 25, and one end of the second anti-corrosion ring 22 is symmetrically connected to a fixing block 23. The fixing block 23 is connected to the inside of the fixing slot 25 by insertion.

[0036] After the tail shaft housing 11 and the short shaft housing 12 are installed, the fixing block 23 is inserted into the inside of the fixing slot 25, so that the first anti-corrosion ring 21 and the second anti-corrosion ring 22 completely surround the outer surface of the mounting plate 24. In this way, when the tail shaft housing 11 and the short shaft housing 12 are immersed, water is prevented from contacting the mounting plate 24.

[0037] The fixing block 23 and the fixing slot 25 are irregularly shaped, and the first anti-corrosion ring 21 and the second anti-corrosion ring 22 are in a corresponding form.

[0038] After the fixing block 23 is inserted into the fixing slot 25, the first anti-corrosion ring 21 and the second anti-corrosion ring 22 will be installed and mated together.

[0039] It also includes reinforcing components, which include a fixing block 31, a sliding groove 32, a fixing hole 33, a fixing rod 34, a fixing frame 35, and a fixing rod 34;

[0040] A set of fixing blocks 31 are symmetrically connected to the outer surfaces of the tail shaft housing 11 and the short shaft housing 12. The fixing blocks 31 have a sliding groove 32 inside. The two sides of the fixing frame 35 are connected to sliders 36. The sliders 36 are movably connected inside the sliding groove 32. The fixing frame 35 is clamped between the first anti-corrosion ring 21 and the second anti-corrosion ring 22.

[0041] The slider 36 slides inside the groove 32, causing the top and bottom fixing brackets 35 to move to the upper and lower parts respectively, facilitating the installation of the first anti-corrosion ring 21 and the second anti-corrosion ring 22.

[0042] A fixing hole 33 is opened in the middle of the top of the fixing block 31, and a fixing rod 34 is connected to the middle of the top of the slider 36. The fixing rod 34 is connected to the inside of the fixing hole 33 by insertion.

[0043] When the mounting bracket 35 moves, the fixing rod 34 can be inserted into the fixing hole 33 to fix the moved mounting bracket 35.

[0044] Working principle: First, the slider 36 slides inside the slide groove 32, moving the top and bottom fixing brackets 35 to the upper and lower parts respectively, while the fixing rod 34 is inserted into the fixing hole 33 to fix the moved fixing brackets 35.

[0045] Next, the fixing block 23 is installed and connected with the fixing slot 25 so that the first anti-corrosion ring 21 and the second anti-corrosion ring 22 are installed and surround the outer surface of the mounting plate 24. Then the slider 36 slides inside the slide groove 32, the fixing rod 34 separates from the fixing hole 33, and the fixing frame 35 is clamped between the first anti-corrosion ring 21 and the second anti-corrosion ring 22.

[0046] The first anti-corrosion ring 21 and the second anti-corrosion ring 22 are mixed with anti-corrosion materials. This prevents water from coming into contact with the mounting plate 24 after the tail shaft housing 11 and the short shaft housing 12 are immersed. This makes it easier to disassemble the mounting plate 24 and fasteners later, and they can be used again after disassembly.

[0047] Please see Figure 1-3 As shown, this embodiment is based on the above embodiment 1, and further includes a fixing component. The fixing component includes a reinforcing ring 41, a protective ring 42, a sealing gasket 43, a compression ring 44, a limiting ring 45, a pull rod 46, and a spring 47.

[0048] The other end of the outer surface of the tail shaft housing 11 is connected to a protective ring 42. A sealing gasket 43 is bonded to the inner wall of the protective ring 42. A reinforcing ring 41 surrounds the outer surface of the sealing gasket 43. A compression ring 44 is installed inside the reinforcing ring 41. A limiting ring 45 is connected to one side of the compression ring 44. A spring 47 is connected to the top of the compression ring 44. A pull rod 46 is connected to both ends of the compression ring 44. The pull rod 46 passes through the reinforcing ring 41.

[0049] The compression ring 44 is pressed against the top of the sealing gasket 43 by the spring 47, and the limiting ring 45 can prevent the sealing gasket 43 from deforming after long-term use.

[0050] The compression ring 44 is attached to the outer surface of the sealing gasket 43, while the limiting ring 45 is connected to one side of the sealing gasket 43.

[0051] Working principle: First, the protective ring 42 is installed on the other side of the tail shaft housing 11, and the sealing gasket 43 is attached to the outer surface of the other side of the tail shaft housing 11. Then, the reinforcing ring 41 is installed on the outside of the sealing gasket 43. Pull the pull rod 46, and use the elastic force of the spring 47 to make the compression ring 44 press against the top of the sealing gasket 43, while the limiting ring 45 blocks one side of the sealing gasket 43.

[0052] The compression of the compression ring 44 can prevent the sealing gasket 43 from developing gaps after long-term use, while the limiting ring 45 can prevent the sealing gasket 43 from deforming after long-term use, thus improving the sealing performance.

[0053] After the sealing gasket 43 is installed, the compression ring 44 is pressed against the top of the sealing gasket 43 by the spring 47, while the limiting ring 45 blocks one side of the sealing gasket 43. The compression of the sealing gasket 43 by the compression ring 44 can prevent the sealing gasket 43 from developing gaps after long-term use, while the limiting ring 45 can prevent the sealing gasket 43 from deforming after long-term use, thus improving the sealing performance.
