Abstract
Description
Technical Field
[0001] This invention relates to the field of support tooling technology, and in particular to a support device and a support assembly for a tanker shaft assembly. Background Technology
[0002] In the shipbuilding industry, tanker shaft generator assemblies typically include large components such as shaft-driven generators, PTO shafts, intermediate shafts, and intermediate bearings. To improve production efficiency and reduce high-altitude operations and handling frequency in the dry dock, these components are often pre-assembled into shaft generator assemblies in the dry dock area before being hoisted onto the ship as a whole using a dry dock gantry crane. During shaft generator assembly, large shaft sections such as the PTO shaft and intermediate shaft need to be placed on support devices for alignment, connection, and fastening. These shaft sections are heavy, long, and require high assembly precision, necessitating support devices that simultaneously meet multiple requirements, including load-bearing capacity, stability, and precision maintenance. Existing support methods struggle to simultaneously meet the comprehensive requirements of versatility, lightweight design, and ease of operation in shaft generator assembly.
[0003] Therefore, there is an urgent need to develop a new type of support device to meet the combined requirements of lightweight design and ease of operation. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to overcome the defects of the prior art, such as the large weight of the support device leading to difficulty in handling and easy mismatch, and to provide a support device and a support component for oil tanker shaft assembly.
[0005] The present invention solves the above-mentioned technical problems through the following technical solution:
[0006] A support device includes a support device body, which is a hollow frame assembled from multiple profiles. The support device body is mirror-symmetrical about three central planes about its length, width and height directions.
[0007] The hollow frame structure significantly reduces the weight of the device while ensuring load-bearing capacity, saving materials. The symmetry of the three mutually orthogonal central planes allows the support device to be placed without orientation, enabling direct use without needing to determine direction and improving on-site operational efficiency.
[0008] Preferably, the main body of the support device consists of multiple first components extending along the length direction, multiple second components extending along the width direction, and multiple third components extending along the height direction. The first, second, and third components are all rods made of equilateral angle steel. The first and second components are symmetrically arranged at both ends in the height direction to form an upper support structure and a lower support structure, respectively. The multiple third components are vertically connected between the upper support structure and the lower support structure.
[0009] The standardized arrangement of standard rods creates a perfectly symmetrical support frame, resulting in a simple structure that is quick to assemble. Both ends can be used as supports, further enhancing the device's versatility.
[0010] Preferably, the same number of the third components are provided on both sides of the main body of the support device in the width direction, and the two ends of each third component are vertically connected to the intersection formed by the first component and the second component on the same side.
[0011] The third component is evenly distributed on both the front and rear sides and connects at the intersection of the first and second components, so that the load is transferred to the ground through the shortest path. The structure is reasonably stressed, the node connection is reliable, and the overall rigidity is good.
[0012] Preferably, all the profiles are equal-sided angle steel of the same specification.
[0013] The main body of the support device uses equilateral angle steel of the same specification, which reduces the types of profiles, makes it easier to use existing surplus materials on site, reduces material procurement and management costs, and improves production efficiency.
[0014] Preferably, the opening of the first component faces outward from the main body of the support device, such that one plane of the first component forms a support surface extending outward in the width direction and the other plane of the first component forms a reinforcing rib extending in the height direction.
[0015] By utilizing the perpendicularity of the two sides of the angle steel, one side forms a flat support to securely hold the shaft section, while the other side also serves as a reinforcing rib to improve load-bearing capacity. No additional welding of ribs is required, simplifying the structure.
[0016] Preferably, the support device further includes at least two diagonal bracing structures, which are symmetrically connected to the outer ends of the main body of the support device in the width direction.
[0017] Diagonal bracing structures are installed on both sides in the width direction to effectively increase the contact span between the device and the ground, prevent the device from tipping over, and ensure stable and reliable support.
[0018] Preferably, each of the diagonal bracing structures includes a fourth component and a fifth component, one end of the fourth component is fitted and connected to the side of the third component, the other end of the fourth component is connected to the fifth component, and the fifth component constitutes the bottom pad of the support device.
[0019] The diagonal bracing structure is connected by side fitting, resulting in a compact structure; the square steel plate at the bottom serves as a base plate, increasing the contact area with the ground, preventing the support device from sliding during use, and further improving stability.
[0020] Preferably, the fourth component and the main body of the support device are made of equal-sided angle steel of the same specification;
[0021] Alternatively, the side of the fourth component that is in contact with the third component may be a folded structure, while the side of the fourth component that is in contact with the fifth component may be a planar structure.
[0022] The fourth component and the main body of the support device use equilateral angle steel of uniform specifications, which further reduces the types of profiles, facilitates batch cutting and on-site fabrication, and improves overall manufacturing efficiency.
[0023] Preferably, the load-bearing capacity of a single support device body is configured to be no less than the total weight of the object to be supported.
[0024] A single support device can bear the entire weight of the object to be supported, ensuring that it will not fail due to overload even under extreme stress conditions, making it safe and reliable to use.
[0025] The present invention also provides a support assembly for a tanker shaft and generator assembly, the support assembly for the tanker shaft and generator assembly comprising a plurality of support devices as described above, the support devices being supported below the PTO shaft and / or intermediate shaft of the tanker shaft and generator assembly, the width direction of the main body of the support device being configured to be consistent with the extension direction of the tanker shaft and generator assembly.
[0026] The length of the support device is greater than its width. The longer length direction is perpendicular to the axis system to provide sufficient support span, while the shorter width direction is parallel to the axis system, which realizes the miniaturization of the structure and makes it easy to arrange flexibly in narrow spaces.
[0027] The positive and progressive effects of this invention are as follows: the hollow frame structure significantly reduces the weight of the device while ensuring load-bearing capacity, thus saving materials. The symmetry of the three mutually orthogonal central planes allows the support device to be placed without orientation, enabling direct use without needing to determine direction, thereby improving on-site operational efficiency.

[0051] The present invention will be described more clearly and completely below with reference to a preferred embodiment and the accompanying drawings.
[0052] Example 1
[0053] like Figures 1-5As shown, the present invention provides a support device 20, which includes a support device body 21. The support device body 21 is a hollow frame assembled from multiple profiles. The profiles are equilateral angle steel with dimensions of 100mm*100mm*10mm (both sides are 100mm wide and 10mm thick). The support device body 21 is mirror-symmetrical about its three central planes in the length, width, and height directions. The support device body 21 consists of four first components 211 extending along the length direction, six second components 212 extending along the width direction, and six third components 213 extending along the height direction. The first components 211, second components 212, and third components 213 are all rods made of equilateral angle steel. The length of the first component 211 is 1300mm, the length of the second component 212 is 100mm, and the length of the third component 213 is 742mm. Two first components 211 and three second components 212 are symmetrically arranged at both ends in the height direction to form an upper support structure and a lower support structure respectively, and six third components 213 are vertically connected between the upper support structure and the lower support structure.
[0054] In this embodiment, the hollow frame structure significantly reduces the weight of the device while ensuring load-bearing capacity, saving materials. The symmetry of the three mutually orthogonal central planes allows the support device 20 to be placed without orientation, enabling direct use without needing to determine direction, thus improving on-site operational efficiency. In other embodiments, the support device 20 can also be made of other types or quantities of profiles according to actual usage requirements; this part is prior art and will not be elaborated further here.
[0055] like Figures 1-5 As shown, the main body 21 of the support device consists of four first components 211 extending along the length direction, six second components 212 extending along the width direction, and six third components 213 extending along the height direction. The first components 211, second components 212, and third components 213 are all rods made of equilateral angle steel. The first components 211 and second components 212 are symmetrically arranged at both ends in the height direction to form an upper support structure and a lower support structure, respectively. The multiple third components 213 are vertically connected between the upper support structure and the lower support structure.
[0056] In this embodiment, a frame structure that is completely symmetrical from top to bottom is formed by the regular layout of the rods composed of equilateral angle steel, which is simple in structure and quick to assemble.
[0057] like Figures 1-5 As shown, three third components 213 are provided on each side of the support device body 21 in the width direction. The two ends of each third component 213 are vertically connected to the intersection formed by the first component 211 and the second component 212 on the same side.
[0058] In this embodiment, the third component 213 is evenly distributed on the front and rear sides and is connected at the intersection of the first component 211 and the second component 212, so that the load is transmitted to the ground through the shortest path, the structure is reasonably stressed, the node connection is reliable, and the overall rigidity is good.
[0059] like Figures 1-5 As shown, the profiles used in the main body 21 of the support device are all equal-sided angle steel of the same specification (100mm*100mm*10mm).
[0060] In this embodiment, the main body 21 of the support device is made of equal-sided angle steel of the same specification, which reduces the types of profiles, facilitates the use of existing surplus materials on site, reduces material procurement and management costs, and improves manufacturing efficiency.
[0061] like Figures 1-5 As shown, the opening of the first component 211 faces the outside of the support device body 21, so that one plane of the first component 211 forms a support surface extending outward in the width direction and the other plane of the first component 211 forms a reinforcing rib extending in the height direction.
[0062] In this embodiment, the perpendicularity of the two sides of the angle steel is utilized. One side forms a flat support to securely support the shaft section, while the other side also serves as a reinforcing rib to improve the load-bearing capacity. No additional welding of ribs is required, simplifying the structure.
[0063] like Figures 1-5 As shown, the support device 20 also includes two diagonal bracing structures 22, which are symmetrically connected to the outer ends of the support device body 21 in the width direction.
[0064] In this embodiment, diagonal bracing structures 22 are provided on both sides in the width direction, which effectively increases the contact span between the device and the ground, prevents the device from tipping over, and ensures stable and reliable support.
[0065] like Figures 1-5 As shown, each diagonal bracing structure 22 includes a fourth component 221 and a fifth component 222. One end of the fourth component 221 is attached to the side of the third component 213, and the other end of the fourth component 221 is connected to the fifth component 222. The fifth component 222 constitutes the bottom pad of the support device 20.
[0066] In this embodiment, the diagonal bracing structure 22 is connected by side fitting, resulting in a compact structure; the square steel plate at the bottom serves as a bottom pad, increasing the contact area with the ground and preventing the support device 20 from sliding during use, thus further improving stability.
[0067] like Figures 1-5As shown, the fourth component 221 is cut from a parallelogram steel plate of 520mm*145mm*10mm. The side of the fourth component 221 that is attached to the third component 213 has a folded corner structure. The side of the fourth component 221 that is attached to the fifth component 222 is the short side of the fourth component 221. The fifth component 222 is a steel plate of 150mm*150mm*10mm.
[0068] like Figures 1-5 As shown, the load-bearing capacity of a single support device body 21 is configured to be no less than the total weight of the object to be supported.
[0069] In this embodiment, a single support device 20 can bear the entire weight of the object to be supported, ensuring that it will not fail due to overload even under extreme stress conditions, making it safe and reliable to use.
[0070] like Figure 1 As shown, the present invention also provides a support assembly for a tanker shaft generator assembly 10. The support assembly for the tanker shaft generator assembly 10 includes two support devices 20 as described above. The support devices 20 are supported below the POT shaft 14 and intermediate shaft 12 on both sides of the intermediate bearing 13 of the tanker shaft generator assembly 10. The width direction of the support device body 21 is configured to be consistent with the extension direction of the tanker shaft generator assembly 10. In other embodiments, the support device 20 may also be located below the temporary shaft 11. Simultaneously, the sum of the height of the support device 20 and the radius of the tanker shaft generator assembly 10 is the same as the height of the center hole of the shaft-driven generator 15, thereby ensuring that the shaft center of the tanker shaft generator assembly 10 and the center hole of the shaft-driven generator 15 are located on the same straight line.
[0071] In this embodiment, the length of the support device 20 is greater than its width. The longer length direction is perpendicular to the axis to provide sufficient support span, while the shorter width direction is parallel to the axis, thus achieving structural miniaturization and facilitating flexible arrangement in narrow spaces.
[0072] Example 2
[0073] like Figures 6-8 As shown, the difference from Embodiment 1 is that the fourth component 221 and the main body 21 of the support device in this embodiment are made of the same specification of equilateral angle steel and are adapted to be connected to the side of the third component 213.
[0074] In this embodiment, the fourth component 221 and the main body of the support device 21 are made of equilateral angle steel of the same specification, which further reduces the types of profiles, facilitates batch cutting and on-site fabrication, and improves the overall manufacturing efficiency.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
