Description

Technical Field

[0001] This invention relates to the field of marine technology, and in particular to a shaft engine assembly support device and a method for assembling the support device. Background Technology

[0002] Car carriers capable of carrying 10,000 vehicles typically employ a stern-engine direct propulsion system. This means a single main engine is located at the stern, directly driving the propeller via a long shaft system. A shaft-driven generator is connected in series within this shaft system. The main components include the main engine, intermediate shaft, stern shaft, generator shaft, propeller shaft, propeller, generator, and related auxiliary devices. To improve assembly efficiency and reduce the frequency of component lifting and handling, the generator and generator shaft are usually pre-assembled into a generator assembly during construction. This assembly can weigh approximately 40 tons, and is then lifted onto the ship as a whole using a dockside gantry crane for installation.

[0003] During installation, to avoid interference between the main engine and other structures and the shaft-driven generator, and to ensure the safety of the shaft-driven generator assembly, the assembly needs to be lifted and supported for a period of time. The shaft system installation is completed only after the main engine has successfully entered the engine room, the stern tube epoxy resin casting is finished, and the bearing slope has passed inspection. However, existing technology does not include a dedicated support device specifically designed for the shaft-driven generator assembly. Temporary support devices are insufficient to meet the strength requirements of the heavy shaft-driven generator assembly, the support structure is incompatible with the stern shaft structure, and it is difficult to quickly dismantle the support after the shaft system installation is complete. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the existing technology that the support device is difficult to meet the support strength and structural requirements of the shaft assembly and is not easy to disassemble, and to provide a shaft assembly support device and a support device assembly method.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] The present invention provides a shaft-driven generator assembly support device, the shaft-driven generator assembly support device including a shaft-driven generator support device and at least two shaft-driven generator shaft support devices, wherein the shaft-driven generator support device is disposed inside the at least two shaft-driven generator shaft support devices;

[0007] The shaft-driven generator support device includes at least two pairs of spaced-apart first columns and connectors. The lower end of the first column is used to connect to the deck of the ship, and the upper end of the first column is used to support the shaft-driven generator. The two ends of the connector are respectively connected to different first columns.

[0008] The shaft support device includes a second column, the lower end of which is used to connect to the deck of the ship, and the upper end of which is used to support the shaft.

[0009] In this solution, by separately setting up a shaft-driven generator support device and at least two shaft-driven generator shaft support devices, and placing the shaft-driven generator support device inside the shaft-driven generator shaft support device, a collaborative support structure is formed. This structure can reliably support both the shaft-driven generator and the shaft-driven generator shaft simultaneously, meeting the structural characteristics and support requirements of different components in the shaft-driven generator assembly. The shaft-driven generator support device forms a stable support frame through the combination of at least two pairs of first columns and connectors, significantly improving the support stiffness and load-bearing capacity, and meeting the support strength requirements of the shaft-driven generator. The components of the shaft-driven generator assembly support device can be assembled through modular connections and can be transported and installed individually, facilitating installation in confined spaces within the dock and enabling rapid disassembly after shaft system installation, thus overcoming the shortcomings of existing support devices that are inconvenient to install and disassemble.

[0010] Preferably, the connector includes a first connector and a second connector, the first connector being extended along the width direction of the shaft-driven generator, and the second connector being extended along the axial direction of the shaft-driven generator. The first connector, the second connector, and the first column together form a frame structure.

[0011] In this solution, by setting a first connector extending along the width direction of the shaft-driven generator and a second connector extending along the axial direction of the shaft-driven generator, the first connector, the second connector, and the first column together form a frame structure, which enhances the overall structural strength of the shaft-driven generator support device in two directions, making the shaft-driven generator support device more stable and reliable, avoiding deformation or instability of the support structure due to excessive weight of the shaft-driven generator, and further improving the load-bearing safety.

[0012] Preferably, the shaft-driven generator support device further includes a first diagonal brace, one end of which is connected to the first column, and the other end of which is used to connect to the deck of the ship.

[0013] In this solution, by connecting one end of the first diagonal brace to the first column and the other end of the first diagonal brace to the ship deck, the lateral stability of the first column is enhanced. This effectively resists the overturning moment generated when the shaft-driven generator is placed, preventing tilting or falling during the support process, and further improving the stability and safety of the shaft-driven generator support device.

[0014] Preferably, the connector extends horizontally, and both ends of the connector are connected to the middle of the first column along its height direction. The upper end of the first diagonal brace and the connector are located at the same height position of the first column along its height direction.

[0015] In this solution, by setting the upper end of the first diagonal brace and the connector at the same height position along the height direction of the first column, the forces of the first diagonal brace and the connector can work together, optimizing the stress state of the first column and further improving the stability and safety of the shaft-driven generator support device.

[0016] Preferably, the first column is provided with a plurality of first connecting parts, the connecting parts are detachably connected to the first connecting parts, one end of the first diagonal brace is detachably connected to the first connecting part, and the other end of the first diagonal brace is used to detachably connect to the deck of the ship.

[0017] In this design, multiple first connecting parts are installed on the first column. Both the connector and the first diagonal brace are detachably connected to these first connecting parts, achieving a prefabricated connection between the connector, the first diagonal brace, and the first column. This eliminates the need for on-site welding, making installation and disassembly more convenient and faster. One end of the first diagonal brace is detachably connected to the first connecting part, and the other end is detachably connected to the ship's deck. The detachable nature of both ends of the first diagonal brace facilitates its installation and disassembly, improving construction efficiency.

[0018] Preferably, the shaft support device further includes a second diagonal brace, one end of which is connected to the second column, and the other end of which is used to connect to the deck of the ship.

[0019] In this design, the lateral stability of the shaft support device is enhanced by installing a second diagonal brace on the second column. Since the second column is a single-column structure, its resistance to lateral overturning is relatively weak. The second diagonal brace effectively resists the lateral forces generated when the shaft is placed, preventing the second column from tipping over and ensuring the safety and reliability of the shaft support device.

[0020] Preferably, the second column is provided with a plurality of second connecting parts, one end of the second diagonal brace is detachably connected to the second connecting part, the other end of the second diagonal brace is used for detachably connecting to the deck of the ship, and the second connecting part is located at the middle of the second column along its height direction.

[0021] In this design, by placing the second connecting part at the midpoint of the second column along its height, the support point of the second diagonal brace is rationally positioned, providing effective lateral support. Both ends of the second diagonal brace are detachable, simplifying installation and disassembly. This allows construction workers to quickly assemble and disassemble the brace within the confined space of the small dock, improving construction efficiency.

[0022] Preferably, the upper end of the second column is provided with a support portion, the support portion being used to support the support surface of the shaft and matching the shape of the shaft, and the lower end of the support portion is provided with a first reinforcing member.

[0023] In this design, by setting the support surface of the support part to match the shape of the hair shaft, the contact area between the support surface and the hair shaft is increased, avoiding damage to the hair shaft due to excessive local pressure. Simultaneously, it restricts the rolling of the hair shaft during the support process, preventing it from rolling off. A first reinforcing member is provided at the lower end of the support part, enhancing its structural strength and enabling it to reliably bear the weight of the hair shaft, thus improving the stability and safety of the hair shaft support device.

[0024] Preferably, the second column is provided with positioning holes, and the positioning holes of different second columns are located at the same vertical height. The positioning holes are used for positioning between different second columns, and a second reinforcing member is provided around the positioning holes.

[0025] In this design, positioning holes at the same vertical height are set on different second columns to facilitate positioning by stringing and lighting during installation, ensuring the alignment of multiple second columns and thus guaranteeing the accuracy of their installation. Secondary reinforcing members are installed around the positioning holes to compensate for any weakening of the second columns' strength caused by the positioning holes, ensuring that the overall load-bearing capacity of the second columns is not affected.

[0026] The present invention also provides a method for assembling a support device, which utilizes the aforementioned shaft assembly support device and includes the following construction steps:

[0027] Step S1: Install the shaft-driven generator support device and at least two shaft-driven generator support devices on the deck of the ship;

[0028] Step S2: Place the shaft-driven generator on the shaft-driven generator support device, and place both ends of the shaft-driven generator shaft on at least two shaft-driven generator support devices respectively;

[0029] Step S3: After the main unit is installed, install the shaft-driven generator and the shaft-driven generator shaft.

[0030] Step S4: Disassemble the shaft-driven generator support device and the shaft-driven generator shaft support device.

[0031] In this scheme, the support device is first installed, and then the shaft-driven generator is placed on the shaft-driven generator support device. Both ends of the shaft-driven generator shaft are placed on at least two shaft-driven generator shaft support devices. After the main unit is installed, the shaft system is installed. Finally, the shaft-driven generator support device and the shaft-driven generator shaft support device are disassembled. This ensures that the shaft-driven generator assembly support device can stably and reliably support the shaft-driven generator assembly, preventing damage to the shaft-driven generator assembly during the installation of the main unit and other structures. The shaft-driven generator assembly support device is easy to install and disassemble, convenient to operate, and easy for construction personnel to operate.

[0032] The positive and progressive effects of this invention are as follows:

[0033] This invention provides a shaft-driven generator assembly support device. By separately arranging a shaft-driven generator support device and at least two shaft-driven generator shaft support devices, with the generator support device positioned inside the generator shaft support device, a collaborative support structure is formed. This structure can reliably support both the generator and the generator shaft simultaneously, meeting the structural characteristics and support requirements of different components in the shaft-driven generator assembly. The generator support device forms a stable support frame through the combination of at least two pairs of first columns and connectors, significantly improving support stiffness and load-bearing capacity, thus meeting the support strength requirements of the generator. The components of the generator assembly support device can be assembled using modular connections and can be transported and installed individually, facilitating installation in confined spaces within a dry dock and enabling rapid disassembly after shaft system installation, overcoming the shortcomings of existing support devices that are inconvenient to install and disassemble.

[0061] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the following embodiments.

[0062] like Figures 1-5 As shown, this embodiment provides a shaft-driven generator assembly support device 10, which includes a shaft-driven generator support device 20 and at least two shaft-driven generator support devices 30. The shaft-driven generator support device 20 is disposed inside the at least two shaft-driven generator support devices 30.

[0063] The shaft-driven generator support device 20 includes at least two pairs of spaced-apart first columns 210 and connectors 220. The lower end of the first column 210 is used to connect to the deck 3 of the ship, and the upper end of the first column 210 is used to support the shaft-driven generator 1. The two ends of the connectors 220 are respectively connected to different first columns 210. The shaft-driven generator support device 30 includes a second column 310. The lower end of the second column 310 is used to connect to the deck 3 of the ship, and the upper end of the second column 310 is used to support the shaft-driven generator 2.

[0064] By separately setting up a shaft-driven generator support device 20 and at least two shaft-driven generator shaft support devices 30, and placing the shaft-driven generator support device 20 inside the shaft-driven generator shaft support device 30, a cooperative support structure is formed, which can reliably support both the shaft-driven generator 1 and the shaft-driven generator shaft 2 simultaneously, meeting the structural characteristics and support requirements of different components in the shaft-driven generator assembly. The shaft-driven generator support device 20 forms a stable support frame through the combination of at least two pairs of first columns 210 and connectors 220, which significantly improves the support stiffness and load-bearing capacity, and can meet the support strength requirements of the shaft-driven generator 1. The components of the shaft-driven generator assembly support device 10 can be assembled through modular connection and can be transported and installed separately, which is convenient for installation in the confined space of the dock and also facilitates quick disassembly after the shaft system is installed, solving the defects of existing support devices that are inconvenient to install and disassemble.

[0065] In this embodiment, there are four first columns 210, and the four first columns 210 and the connectors 220 form a cuboid frame structure. In other embodiments, other numbers and arrangements of the first columns 210 that are deemed suitable by those skilled in the art can also be selected.

[0066] In this embodiment, the first column 210 and the second column 310 are made of 100*100*10 equilateral angle steel and HW200*200 steel, which are readily available and inexpensive, thus improving the manufacturing efficiency of the shaft-driven generator assembly support device 10. In other embodiments, other materials deemed suitable by those skilled in the art for the first column 210 may also be used. During manufacturing, it is ensured that the shaft-driven generator support device 20 and the shaft-driven generator shaft support device 30 are at the same height as the center of the shaft-driven generator 1 and the center of the shaft-driven generator shaft 2. To ensure structural strength, considering extreme load-bearing conditions, the load-bearing weight of a single first column 210 is not less than the total weight of the shaft-driven generator 1, and the load-bearing weight of a single second column 310 is not less than the total weight of the shaft-driven generator shaft 2.

[0067] The connector 220 includes a first connector 221 and a second connector 222. The first connector 221 extends along the width direction of the shaft-driven generator 1, and the second connector 222 extends along the axial direction of the shaft-driven generator 1. The first connector 221, the second connector 222, and the first column 210 together form a frame structure. By setting the first connector 221 extending along the width direction of the shaft-driven generator 1 and the second connector 222 extending along the axial direction of the shaft-driven generator 1, the first connector 221, the second connector 222, and the first column 210 together form a frame structure, which enhances the overall structural strength of the shaft-driven generator support device 20 in two directions, making the shaft-driven generator support device 20 more stable and reliable, avoiding deformation or instability of the support structure due to excessive weight of the shaft-driven generator 1, and further improving load-bearing safety.

[0068] The shaft-driven generator support device 20 also includes a first diagonal brace 230, one end of which is connected to the first column 210, and the other end of which is connected to the ship's deck 3. By connecting one end of the first diagonal brace 230 to the first column 210 and the other end of the first diagonal brace 230 to the ship's deck 3, the lateral stability of the first column 210 is enhanced, effectively resisting the overturning moment generated when the shaft-driven generator 1 is placed, preventing tilting or falling during the support process, and further improving the stability and safety of the shaft-driven generator support device 20.

[0069] In this embodiment, each first column 210 is provided with a first diagonal brace 230, which extends obliquely along the axial direction of the shaft-driven generator 1, thereby better optimizing the stress on the shaft-driven generator support device 20 and enhancing the support strength along the axial direction of the shaft-driven generator 1. In other embodiments, other numbers and arrangements of the first diagonal braces 230 that are deemed appropriate by those skilled in the art can also be selected.

[0070] The connector 220 extends horizontally, with both ends connected to the middle of the first column 210 along its height direction. The upper end of the first diagonal brace 230 and the connector 220 are located at the same height position of the first column 210 along its height direction. By setting the upper end of the first diagonal brace 230 and the connector 220 at the same height position of the first column 210 along its height direction, the forces on the first diagonal brace 230 and the connector 220 can work synergistically, optimizing the stress state of the first column 210 and further improving the stability and safety of the shaft-driven generator support device 20.

[0071] The first column 210 is provided with multiple first connecting parts 211. A connector 220 is detachably connected to each first connecting part 211. One end of the first diagonal brace 230 is detachably connected to each first connecting part 211, and the other end of the first diagonal brace 230 is detachably connected to the ship's deck 3. By providing multiple first connecting parts 211 on the first column 210, and by detachably connecting both the connector 220 and the first diagonal brace 230 to each first connecting part 211, an assembly connection of the connector 220, the first diagonal brace 230, and the first column 210 is achieved, eliminating the need for on-site welding and making installation and disassembly more convenient and faster. One end of the first diagonal brace 230 is detachably connected to the first connecting part 211, and the other end is detachably connected to the ship's deck 3. Both ends of the first diagonal brace 230 are detachable, facilitating its installation and disassembly and improving construction efficiency.

[0072] The shaft-driven generator support device 20 also includes a base 240, which is used to mount on the deck 3 of the ship. The lower end of the first column 210 is detachably connected to the base 240. By setting the base 240 on the deck 3 and detachably connecting the lower end of the first column 210 to the base 240, damage to the structure of the deck 3 caused by directly welding or drilling the first column 210 to the deck 3 is avoided. The base 240 can be pre-set on the deck 3, and the first column 210 can be quickly installed on the base 240. It also facilitates quick disassembly from the base 240 after the shafting is completed.

[0073] The shaft support device 30 also includes a second diagonal brace 320. One end of the second diagonal brace 320 is connected to the second column 310, and the other end is used to connect to the deck 3 of the ship. By setting the second diagonal brace 320 on the second column 310, the lateral stability of the shaft support device 30 is enhanced. Since the second column 310 is a single column structure, its own resistance to lateral overturning is relatively weak. The second diagonal brace 320 can effectively resist the lateral force generated when the shaft 2 is placed, preventing the second column 310 from tipping over and ensuring the safety and reliability of the shaft support device 30. Similar to the first diagonal brace 230, those skilled in the art can also select other second diagonal braces 320 that they deem appropriate according to the actual situation.

[0074] In this embodiment, the upper ends of the first diagonal brace 230 and the second diagonal brace 320 are connected to the upper part of the column along the vertical direction. In other embodiments, the upper ends of the first diagonal brace 230 and the second diagonal brace 320 can also be connected to the lower part of the column. Those skilled in the art can select a suitable connection position between the diagonal brace and the column according to actual needs.

[0075] In this embodiment, the angle between the first diagonal brace 230 and the second diagonal brace 320 and the column is set to 30°, such as Figure 3 and Figure 5 As shown, angles A and B are 30°. The angle between the diagonal brace and the column is reasonable, enabling the diagonal brace to provide sufficient lateral support force and further improving the structural stability of the shaft assembly support device 10. In other embodiments, other angles between the diagonal brace and the column that are considered suitable by those skilled in the art can also be selected.

[0076] The second column 310 is provided with multiple second connecting parts 311. One end of the second diagonal brace 320 is detachably connected to the second connecting part 311, and the other end of the second diagonal brace 320 is detachably connected to the deck 3 of the ship. The second connecting parts 311 are located at the middle of the second column 310 along its height direction. By placing the second connecting parts 311 at the middle of the second column 310 along its height direction, the support point of the second diagonal brace 320 is reasonably positioned, providing effective lateral support force. Both ends of the second diagonal brace 320 are detachably connected, making installation and disassembly simple and convenient for construction personnel to quickly assemble and disassemble in the confined space of a small dock, thus improving construction efficiency.

[0077] In this embodiment, the first connecting part 211 and the second connecting part 311 are earring structures with through holes. The diagonal brace is bolted to the connecting part through the through holes. In other embodiments, other specific structures of the first connecting part 211 and the second connecting part 311 that are deemed suitable by those skilled in the art can be selected, as well as other detachable connection methods between the diagonal brace and the connecting part that are deemed suitable by those skilled in the art, not limited to bolted connections.

[0078] The upper end of the second column 310 is provided with a support portion 330. The support portion 330 is used to support the hair shaft 2, and its support surface matches the shape of the hair shaft 2. The lower end of the support portion 330 is provided with a first reinforcing member 340. By setting the support surface of the support portion 330 to match the shape of the hair shaft 2, the contact area between the support surface and the hair shaft 2 is increased, avoiding damage to the hair shaft 2 due to excessive local pressure. At the same time, it can limit the rolling of the hair shaft 2 during the support process and prevent the hair shaft 2 from rolling off. The first reinforcing member 340 at the lower end of the support portion 330 enhances the structural strength of the support portion 330, enabling it to reliably bear the weight of the hair shaft 2 and improving the stability and safety of the hair shaft support device 30.

[0079] In this embodiment, the support surface of the support portion 330 for supporting the shaft 2 is an inwardly concave arc-shaped surface, while the other surfaces of the support member are flat. In other embodiments, other specific shapes of the support portion 330 that are deemed suitable by those skilled in the art may also be selected.

[0080] In this embodiment, the support portion 330 is made of triangular wooden blocks. In other embodiments, other materials that those skilled in the art deem suitable for the support portion 330 may also be selected.

[0081] The second column 310 is provided with positioning holes 312. The positioning holes 312 of different second columns 310 are located at the same vertical height. The positioning holes 312 are used for positioning between different second columns 310. A second reinforcing member 350 is provided around the positioning hole 312. By providing positioning holes 312 at the same vertical height on different second columns 310, it is convenient to use a string line for positioning during installation, ensuring that the positions of multiple second columns 310 are aligned, thereby ensuring the accuracy of the installation position of multiple second columns 310. The second reinforcing member 350 around the positioning hole 312 compensates for the weakening of the strength of the second column 310 caused by the opening of the positioning hole 312, ensuring that the overall load-bearing capacity of the second column 310 is not affected.

[0082] like Figure 6 As shown, this embodiment also provides a method for assembling a support device. The method for assembling the support device utilizes the aforementioned shaft assembly support device 10 and includes the following construction steps:

[0083] Step S1: Install shaft generator support device 20 and at least two shaft generator support devices 30 on the deck 3 of the ship;

[0084] Step S2: Place the shaft-driven generator 1 on the shaft-driven generator support device 20, and place both ends of the shaft-driven generator 2 on at least two shaft-driven generator support devices 30 respectively.

[0085] Step S3: After the main unit is installed, install the shaft-driven generator 1 and the shaft-driven generator shaft 2.

[0086] Step S4: Disassemble the shaft-driven generator support device 20 and the shaft-driven generator shaft support device 30.

[0087] In this scheme, the support device is first installed, and then the shaft-driven generator 1 is placed on the shaft-driven generator support device 20. The two ends of the shaft-driven generator shaft 2 are placed on at least two shaft-driven generator shaft support devices 30. After the main unit is installed, the shaft system is installed. Finally, the shaft-driven generator support device 20 and the shaft-driven generator shaft support device 30 are disassembled. This allows the shaft-driven generator assembly support device 10 to stably and reliably support the shaft-driven generator assembly, preventing damage to the shaft-driven generator assembly during the installation of the main unit and other structures. The shaft-driven generator assembly support device 10 is easy to install and disassemble, convenient to operate, and easy for construction personnel to operate.
