Description

Technical Field

[0001] This invention relates to the field of ship shafting installation technology, and in particular to a coupling moving kit tooling and shafting connection system. Background Technology

[0002] Depending on the ship type and function, a ship's shafting system generally consists of one or more shafts, and can be horizontal or inclined. Connections between adjacent shafts are mostly achieved using sleeve-type hydraulic couplings. Examples include the connection between the propeller shaft and the stern shaft, and the connection between the stern shaft and the intermediate shaft. During shafting installation, the hydraulic coupling is first pre-fitted onto one shaft. Then, when connecting adjacent shafts, the coupling is moved and fitted onto the other shaft. The hydraulic system applies force to both shafts, thus completing the connection between the two adjacent shafts. Before moving the coupling from one shaft to another, precise alignment between adjacent shafts is usually required. Then, using slings and hoists on the ship's structure, the coupling is pulled obliquely onto the other shaft, bringing it into contact with both adjacent shafts simultaneously.

[0003] The aforementioned method of coupling movement presents the following problems: the pulling force of the hand-operated hoist forms an angle with the direction of coupling movement, causing an imbalance between the inner bore axis of the coupling and the shaft axis. Under tension, the outer sleeve exerts a clamping force on the tapered surface of the inner sleeve. The greater the clamping force, the greater the compressive force of the inner sleeve on the shaft, increasing the frictional force during coupling displacement on the shaft. All of these problems can cause jamming during coupling movement, affecting the assembly of the shaft system.

[0004] Therefore, there is an urgent need for a coupling moving kit tooling and shaft connection system to solve the above problems. Summary of the Invention

[0016] As a preferred embodiment of the coupling moving kit tooling provided by the present invention, the pushing device further includes a pushing connecting ear plate and a pushing connecting assembly. The pushing connecting ear plates are respectively provided at both ends of the pushing clamp, and the pushing connecting ear plates at both ends of the two pushing clamps correspond one-to-one and are connected by the pushing connecting assembly.

[0017] As a preferred embodiment of the coupling moving assembly tooling provided by the present invention, the first fixing device includes two first fixing clamps that are detachably connected to each other, and the two first fixing clamps are fastened to the periphery of the first shaft segment structure; and / or,

[0018] The second fixing device includes two second fixing clamps that are detachably connected to each other, and the two second fixing clamps are fastened to the periphery of the outer casing structure.

[0019] As a preferred embodiment of the coupling moving assembly tooling provided by the present invention, the first fixing device further includes a first connecting lug and a first connecting assembly. The first connecting lugs are respectively provided at both ends of the first fixing clamp, and the first connecting lugs at both ends of the two first fixing clamps correspond one-to-one and are connected by the first connecting assembly; and / or,

[0020] The second fixing device further includes a second connecting ear plate and a second connecting component. The two ends of the second fixing clamp are respectively provided with the second connecting ear plate. The second connecting ear plates at both ends of the two second fixing clamps correspond one to one and are connected by the second connecting component.

[0021] As a preferred embodiment of the coupling moving kit tooling provided by the present invention, the first fixing device further includes a first pull lug plate, and the first pull lug plate is provided on the side of the first fixing clamp away from the first shaft segment structure at the middle position.

[0022] The second fixing device also includes a second pull ear plate, and the second fixing clamp is provided on the side opposite to the outer sleeve structure at the middle position;

[0023] The tensioning device is connected between the first tension lug and the second tension lug, which are corresponding to each other in the length direction of the first shaft segment structure.

[0024] As a preferred embodiment of the coupling moving assembly tooling provided by the present invention, a first through hole is provided on the first pull lug plate, a second through hole is provided on the second pull lug plate, the fixed end of the pulling device is hooked on the first through hole, and the pulling end of the pulling device is hooked on the second through hole.

[0025] According to another aspect of the present invention, an object is to provide a shaft connection system comprising a coupling and a coupling movable assembly tooling as described in any of the above embodiments, the coupling being movable along the axial direction of the second shaft segment structure and being fitted onto the mating point of the first shaft segment structure and the second shaft segment structure.

[0026] The beneficial effects of this invention are:

[0027] The coupling movable assembly tooling provided by this invention connects a first shaft segment structure, a second shaft segment structure, and a coupling. The first and second shaft segment structures are coaxially connected, and the coupling is movably fitted onto the second shaft segment structure along its axial direction, capable of being movably fitted at the connection point between the first and second shaft segment structures. The coupling includes an inner sleeve structure and an outer sleeve structure that are nested together. The two ends of the inner sleeve structure along its axial direction are a large inner sleeve end and a small inner sleeve end, respectively. Along the axial direction of the inner sleeve structure, from the large inner sleeve end to the small inner sleeve end, the cross-sectional area of ​​the inner sleeve structure gradually decreases, and the large inner sleeve end extends out of the outer sleeve structure.

The first fixing device has a fixing ring located on the periphery of the first shaft segment structure. The second fixing device has a fixing ring located on the periphery of the outer sleeve structure. That is, the first and second fixing devices can be positioned on the first shaft segment structure and the outer sleeve structure, respectively, providing a connection base for the tensioning device.

[0028] A tensioning device is connected to the first fixing device and the second fixing device, and can pull the second fixing device and the coupling closer to the first fixing device. The pulling direction of the tensioning device is parallel to the axial direction of the first shaft segment structure. This design prevents the pulling force from forming an angle with respect to the axial directions of the first and second shaft segments during the pulling process, thus avoiding unbalanced compression of the inner sleeve structure by the outer sleeve structure and preventing jamming during coupling movement.

[0029] The pushing device is located between the first fixing device and the second fixing device. A fixing ring is disposed at the large end of the inner sleeve and is equipped with a pushing structure. This pushing structure abuts against the outer sleeve structure and can push the outer sleeve structure away from the large end of the inner sleeve. Through this pushing structure, the outer sleeve structure can be moved away from the large end of the inner sleeve, preventing the outer sleeve structure from fitting over the outer circumference of the larger diameter inner sleeve, thus avoiding the problem of the outer sleeve structure squeezing the inner sleeve structure and affecting the smoothness of the coupling's movement.

[0053] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0054] Figure 1 This is a schematic diagram of the coupling movable assembly tooling provided in an embodiment of the present invention being assembled on the coupling, the first shaft segment structure, and the second shaft segment structure. Figure 2 This is a schematic diagram showing the coupling provided in an embodiment of the present invention being fitted at the mating connection between the first shaft segment structure and the second shaft segment structure. (Refer to...) Figure 1 and Figure 2 This embodiment provides a coupling moving assembly tooling and a shaft connection system. The shaft connection system is configured to fit and assemble a first shaft segment structure 1 and a second shaft segment structure 2 that are coaxially connected.

[0055] The shaft connection system includes a coupling 10 and a coupling movable assembly tooling provided in this embodiment. The coupling 10 is movably sleeved on the second shaft segment structure 2 along the axial direction of the second shaft segment structure 2, and can be movably sleeved at the joint between the first shaft segment structure 1 and the second shaft segment structure 2.

[0056] Specifically, the coupling 10 includes an inner sleeve structure 11 and an outer sleeve structure 12 that are nested together. The two ends of the inner sleeve structure 11 along its axial direction are a large inner sleeve end 13 and a small inner sleeve end 14, respectively. Along the axial direction of the inner sleeve structure 11, from the large inner sleeve end 13 to the small inner sleeve end 14, the cross-sectional area of ​​the inner sleeve structure 11 gradually decreases, and the large inner sleeve end 13 extends beyond the outer sleeve structure 12. That is, the side of the inner sleeve structure 11 is inclined relative to the axial direction of the first shaft segment structure 1 and the second shaft segment structure 2.

[0057] More specifically, the coupling moving kit can be connected to the first shaft segment structure 1, the second shaft segment structure 2 and the coupling 10, and can assist the coupling 10 to move from the second shaft segment structure 2 to the docking point of the first shaft segment structure 1 and the second shaft segment structure 2, and avoid the problem of jamming during the movement, thereby improving the smoothness of the coupling kit moving on adjacent shaft segment structures.

[0058] Continue to refer to Figure 1 The coupling moving assembly includes a first fixing device 100, a second fixing device 200, a tensioning device 300, and a pushing device 400. The first fixing device 100 has a retaining ring located on the periphery of the first shaft segment structure 1. The second fixing device 200 has a retaining ring located on the periphery of the outer sleeve structure 12. In other words, the first fixing device 100 and the second fixing device 200 can be positioned on the first shaft segment structure 1 and the outer sleeve structure 12, respectively, providing a connection base for the tensioning device 300.

[0059] The pulling device 300 is connected to the first fixing device 100 and the second fixing device 200. It can pull the second fixing device 200 and the coupling 10 closer to the first fixing device 100. The pulling direction of the pulling device 300 is parallel to the axial direction of the first shaft segment structure 1. With the above arrangement, it is possible to avoid the pulling force direction forming an angle with respect to the axial direction of the first shaft segment structure 1 and the second shaft segment structure 2 during the pulling process, which would cause the outer sleeve structure 12 to cause unbalanced compression on the inner sleeve structure 11, thereby causing jamming during the movement of the coupling 10.

[0060] The pushing device 400 is located between the first fixing device 100 and the second fixing device 200, with a fixing ring disposed at the large end 13 of the inner sleeve and a pushing structure 410 provided. The pushing structure 410 abuts against the outer sleeve structure 12 and can push the outer sleeve structure 12 away from the large end 13 of the inner sleeve. Through the aforementioned pushing structure 410, the outer sleeve structure 12 can be moved away from the large end 13 of the inner sleeve, avoiding the problem that the outer sleeve structure 12 fits around the outer periphery of the inner sleeve large end 13 with a larger diameter, thereby preventing the outer sleeve structure 12 from squeezing the inner sleeve structure 11 and affecting the smoothness of the movement of the coupling 10.

[0061] Figure 3 This is a schematic diagram of the structure of the first fixing device provided in an embodiment of the present invention; Figure 4 This is an exploded structural diagram of the first fixing device provided in an embodiment of the present invention. (Refer to...) Figure 1 , Figure 3 and Figure 4 The first fixing device 100 includes two first fixing clamps 110 that are detachably connected to each other. The two first fixing clamps 110 are fastened to the periphery of the first shaft segment structure 1. Similarly, the second fixing device 200 includes two second fixing clamps 210 that are detachably connected to each other. The two second fixing clamps 210 are fastened to the periphery of the outer casing structure 12. This arrangement facilitates the installation and removal of the first fixing device 100 on the first shaft segment structure 1, and also facilitates the installation and removal of the second fixing device 200 on the outer casing structure 12.

[0062] Specifically, the first fixing device 100 further includes a first connecting ear plate 120 and a first connecting assembly 130. The first fixing clamp 110 has a first connecting ear plate 120 at each end, with the first connecting ear plates 120 at both ends of the two first fixing clamps 110 corresponding one-to-one and connected by the first connecting assembly 130. In this embodiment, the first connecting assembly 130 specifically includes a first bolt 131 and a first nut 132. The first bolt 131 passes through the two corresponding first connecting ear plates 120, and the first nut 132 is screwed onto the first bolt 131. The two first connecting ear plates 120 are tightly clamped between the head of the first nut 132 and the head of the first bolt 131.

[0063] More specifically, the second fixing device 200 further includes a second connecting lug 220 and a second connecting assembly 230. The second fixing clamp 210 has a second connecting lug 220 at each end, with the second connecting lugs 220 at each end of the two second fixing clamps 210 corresponding one-to-one and connected by the second connecting assembly 230. In this embodiment, the second connecting assembly 230 specifically includes a second bolt 231 and a second nut 232. The second bolt 231 passes through the two corresponding second connecting lugs 220, and the second nut 232 is screwed onto the second bolt 231. The two second connecting lugs 220 are tightly clamped between the head of the second nut 232 and the head of the second bolt 231.

[0064] More specifically, the first fixing device 100 further includes a first pull ear plate 140. The first pull ear plate 140 is provided on the side of the first fixing clamp 110 opposite to the first shaft segment structure 1 at its middle position. Similarly, the second fixing device 200 further includes a second pull ear plate 240. The second pull ear plate 240 is provided on the side of the second fixing clamp 210 opposite to the outer sleeve structure 12 at its middle position. The pulling device 300 is connected to the first pull ear plate 140 and the second pull ear plate 240, which correspond to each other in the length direction of the first shaft segment structure 1. Through the first pull ear plate 140 and the second pull ear plate 240, a connection base can be provided for the pulling device 300, realizing a reliable connection between the pulling device 300 and the first fixing device 100 and the second fixing device 200, and providing the pulling device 300 with a pulling direction parallel to the axis of the first shaft segment structure 1.

[0065] More specifically, the first pull ear plate 140 has a first through hole 141, and the second pull ear plate 240 has a second through hole 241. The fixed end of the pulling device 300 is hooked to the first through hole 141, and the pulling end of the pulling device 300 is hooked to the second through hole 241. In this embodiment, the pulling device 300 can specifically be a hand chain hoist, which can be hooked and connected to the first through hole 141 and the second through hole 241, and apply a pulling force to the second pull ear plate 240 based on the first pull ear plate 140.

[0066] Figure 5 This is a schematic diagram of the pushing device provided in an embodiment of the present invention. Figure 6 This is an exploded structural diagram of the pushing device provided in an embodiment of the present invention. Figure 7 This is a side view of the pushing device provided in an embodiment of the present invention. (Refer to...) Figure 1 and Figures 5-7 The pushing device 400 includes two mutually detachable and mating pushing clamps 420, which are fastened to the periphery of the large end 13 of the inner sleeve. This arrangement facilitates the installation and removal of the pushing device 400 on the periphery of the large end 13 of the inner sleeve.

[0067] Specifically, the push clamp 420 has a threaded through hole 421. The push structure 410 is threaded through the threaded through hole 421 in an adjustable relative position. By cooperating with the threaded through hole 421, the length of the push structure 410 protruding from the push clamp 420 away from the first fixed clamp 110 can be adjusted, thereby adjusting the distance between the outer sleeve structure 12 and the inner sleeve large end 13.

[0068] More specifically, there are multiple pushing structures 410, with multiple pushing structures 410 spaced apart circumferentially on the two pushing clamps 420. This arrangement improves the uniformity of the force applied by the pushing structures 410 to the outer sleeve structure 12, ensuring the parallelism between the direction of movement of the outer sleeve structure 12 relative to the inner sleeve structure 11 and the axial directions of the first shaft segment structure 1 and the second shaft segment structure 2.

[0069] More specifically, the pushing device 400 further includes pushing connecting ear plates 430 and pushing connecting assembly 440. Pushing connecting ear plates 430 are respectively provided at both ends of the pushing clamp 420, with each of the pushing connecting ear plates 430 at both ends of the two pushing clamps 420 corresponding to one another and connected by the pushing connecting assembly 440. The pushing connecting assembly 440 specifically includes a pushing connecting bolt 441 and a pushing connecting nut 442. The pushing connecting bolt 441 passes through the two corresponding pushing connecting ear plates 430, and the pushing connecting nut 442 is screwed onto the pushing connecting bolt 441. The two pushing connecting ear plates 430 are tightly clamped between the heads of the pushing connecting nut 442 and the pushing connecting bolt 441.
