Abstract
Description
Technical Field
[0001] This utility model relates to the field of support tooling technology, and in particular to a support tooling for shipbuilding. Background Technology
[0002] In the construction of ships and large steel structures, the mounting and positioning of large modules requires stable supports. The standard practice in shipbuilding is to pre-place the support fixtures in their designated positions before mounting and positioning the large modules.
[0003] Existing support fixtures are mostly welded steel pipe supports. According to actual usage requirements, multiple sets of steel structures are welded to form support fixtures. The support height and support angle of the support fixtures are fixed. When adjusting the support height, wooden blocks are added to the bottom of the support fixtures. However, they cannot be flexibly adjusted according to the construction site. After the support fixtures are used, they need to be disassembled, which often involves cutting the steel structure. This is not conducive to disassembly and subsequent use of the steel pipe structure. Utility Model Content

[0034] This application provides a support fixture for shipbuilding, in which a first hydraulic cylinder, a second hydraulic cylinder, and a third hydraulic cylinder together constitute a drive component. By controlling the extension and retraction stroke of the drive component, the support height of the support fixture can be flexibly adjusted according to actual usage needs, improving the flexibility of the support fixture during use. After use, the support fixture does not need to be disassembled; simply control each drive component to keep the support fixture in a folded state. During use, no on-site assembly is required; simply control each drive component to unfold the support fixture to a specified height, thus solving the technical problems mentioned in the background art.
[0035] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:
[0036] Example 1:
[0037] Please see Figure 1-10This utility model provides a technical solution: a support fixture for shipbuilding, comprising a first support assembly 1, which is connected to and drives a second support assembly 2; the second support assembly 2 is connected to and drives a third support assembly 3; and the third support assembly 3 is connected to and drives a support platform 4. The first support assembly 1 includes a first base plate 11, with first column tubes 12 disposed at the corners of the upper surface of the first base plate 11, each column tube 12 housing a first hydraulic cylinder 13. The second support assembly 2 includes a second base plate 21, with a first drive frame 22 welded and fixed to both sides of the second base plate 21. A second column tube 23 is provided at the corner of the upper surface of the second base plate 21, and a second hydraulic cylinder 24 is built into the second column tube 23. The third support assembly 3 includes a third base plate 31, with a second drive frame 32 welded and fixed to both sides of the third base plate 31. A third column tube 33 is provided at the corner of the upper surface of the third base plate 31, and a third hydraulic cylinder 34 is built into the third column tube 33. The support platform 4 includes a base plate 41 and a support top plate 48.
[0038] The first support component 1 is located at the bottom and connects to the second support component 2. The second support component 2 can be folded inside the first support component 1. The second support component 2 connects to the third support component 3, which can also be folded inside the second support component 2. When the support fixture is not in use, it is in a folded state, such as... Figure 4 and Figure 5 As shown, the third support component 3 is folded inside the second support component 2, and the second support component 2 is folded inside the first support component 1. The structure is compact and easy to transport and store. Therefore, after the support fixture is used, it does not need to be disassembled. You only need to control each drive component to keep the support fixture in a folded state. When using it, there is no need to assemble it on site. You only need to control each drive component to unfold the support fixture to a specified height.
[0039] The support height of the second support assembly 2 is controlled by the extension and retraction stroke of the push rod of the first hydraulic cylinder 13, the support height of the third support assembly 3 is controlled by the extension and retraction stroke of the push rod of the second hydraulic cylinder 24, and the support height of the support platform 4 is controlled by the extension and retraction stroke of the push rod of the third hydraulic cylinder 34. The first hydraulic cylinder 13, the second hydraulic cylinder 24, and the third hydraulic cylinder 34 together constitute the driving component. By controlling the extension and retraction stroke of the driving component, the support height of the support fixture can be flexibly adjusted. It can be adjusted automatically according to actual usage needs, thus improving the flexibility of the support fixture during use.
[0040] The first support assembly 1 includes four sets of first hydraulic cylinders 13, the second support assembly 2 includes four sets of second hydraulic cylinders 24, and the third support assembly 3 includes four sets of third hydraulic cylinders 34. The four sets of first hydraulic cylinders 13 work synchronously, integrating the servo valve with the hydraulic cylinders. Real-time data is fed back through position sensors, and the oil pressure and flow are adjusted using built-in algorithms to achieve high-precision synchronization. Similarly, the four sets of second hydraulic cylinders 24 work synchronously, and the four sets of third hydraulic cylinders 34 work synchronously.
[0041] In some examples, two sets of first horizontal pipes 15 and two sets of first inclined pipes 16 are provided between the two sets of first column pipes 12. The two sets of first inclined pipes 16 are located between the two sets of first horizontal pipes 15 and are arranged crosswise. The first horizontal pipes 15, the first inclined pipes 16 and the first column pipes 12 are welded and fixedly connected.
[0042] like Figure 6 As shown, the first horizontal tube 15 and the first inclined tube 16 are welded and fixed between the two sets of first column tubes 12. The first horizontal tube 15 and the first inclined tube 16 improve the structural strength of the first support component 1, enhance the support capacity of the first support component 1, and prevent deformation.
[0043] In some examples, a first connector 14 is fixedly provided at one end of the push rod of the first hydraulic cylinder 13, and four sets of first connecting seats 26 are welded and fixed on the first drive frame 22 of the second support assembly 2, and the first connecting seats 26 correspond one-to-one with the first connector 14. The first connector 14 and the first connecting seats 26 are fixedly connected by bolts.
[0044] The first support component 1 and the second support component 2 are detachable, allowing for individual replacement of either component, which facilitates subsequent maintenance. When the push rod of the first hydraulic cylinder 13 moves, it drives the first connecting seat 26 at one end, which in turn drives the first drive frame 22, thereby driving the entire second support component 2 to move, allowing for flexible adjustment of the support height of the second support component 2.
[0045] In some examples, two sets of second horizontal pipes 27 and two sets of second inclined pipes 28 are provided between the two sets of second column pipes 23. The two sets of second inclined pipes 28 are located between the two sets of second horizontal pipes 27 and are arranged crosswise. The second horizontal pipes 27, the second inclined pipes 28 and the second column pipes 23 are welded and fixedly connected.
[0046] like Figure 7 As shown, the second horizontal tube 27 and the second inclined tube 28 are welded and fixed between the two sets of second column tubes 23. The second horizontal tube 27 and the second inclined tube 28 improve the structural strength of the second support component 2, enhance the support capacity of the second support component 2, and prevent deformation.
[0047] A second connector 25 is fixedly installed at one end of the push rod of the second hydraulic cylinder 24. Four sets of second connector seats 36 are welded and fixed on the second drive frame 32 of the third support assembly 3, and the second connector seats 36 correspond one-to-one with the second connector heads 25. The second connector heads 25 and the second connector seats 36 are fixedly connected by bolts.
[0048] The second support component 2 and the third support component 3 are detachable, allowing for individual replacement of either component, which facilitates subsequent maintenance. When the push rod of the second hydraulic cylinder 24 moves, it drives the second connecting seat 36 at one end, which in turn drives the second drive frame 32, thereby driving the entire third support component 3 to move, allowing for flexible adjustment of the support height of the third support component 3.
[0049] In some examples, two sets of third horizontal pipes 37 and two sets of third inclined pipes 38 are provided between the two sets of third column pipes 33. The two sets of third inclined pipes 38 are located between the two sets of third horizontal pipes 37 and are arranged crosswise. The third horizontal pipes 37, the third inclined pipes 38 and the third column pipes 33 are welded and fixedly connected.
[0050] like Figure 8 As shown, the third horizontal tube 37 and the third inclined tube 38 are welded and fixed between the two sets of third column tubes 33. The third horizontal tube 37 and the third inclined tube 38 improve the structural strength of the third support component 3, enhance the support capacity of the third support component 3, and prevent deformation.
[0051] In some examples, a third connector 35 is fixedly provided at one end of the push rod of the third hydraulic cylinder 34, and a third connector 49 is welded and fixed at the corner of the lower end face of the base plate 41. The third connector 49 corresponds one-to-one with the third connector 35, and the third connector 35 and the third connector 49 are fixedly connected by bolts.
[0052] The third support component 3 and the support platform 4 are detachable, allowing for individual replacement of either the third support component 3 or the support platform 4, which facilitates subsequent maintenance. When the push rod of the third hydraulic cylinder 34 moves, it drives the third connector 35 at one end, which in turn drives the third connector 49, which in turn drives the base plate 41, thereby driving the overall support platform 4 and allowing for flexible adjustment of the support height of the support platform 4.
[0053] By adopting the above technical solution:
[0054] The support fixture consists of a first support component 1, a second support component 2, a third support component 3, and a support platform 4. The first support component 1 can drive the second support component 2, the second support component 2 can drive the third support component 3, and the third support component 3 can drive the support platform 4. The first hydraulic cylinder 13, the second hydraulic cylinder 24, and the third hydraulic cylinder 34 together constitute the driving component. By controlling the extension and retraction stroke of the driving component, the support height of the support fixture can be flexibly adjusted. It can be adjusted automatically according to actual usage needs, thus improving the flexibility of the support fixture during use.
[0055] The second support component 2 can be folded inside the first support component 1, and the third support component 3 can be folded inside the second support component 2. The structure is compact, which is conducive to transportation and storage. After the support fixture is used, there is no need to disassemble it. Just control each drive component to keep the support fixture in the folded state. When using it, there is no need to assemble it on site. Just control each drive component to unfold the support fixture to the specified height.
[0056] Example 2:
[0057] Based on Example 1, this example describes the specific structure of the support platform 4 in a support fixture for shipbuilding. A mounting frame is welded and fixed on the base plate 41, and a first motor reducer 42 is mounted on the mounting frame. The output shaft of the first motor reducer 42 is fixedly connected to the drive gear 43. A driven gear 44 is rotatably arranged on the base plate 41, and the driven gear 44 meshes with the drive gear 43. Two sets of upright plates 45 are fixedly arranged on the driven gear 44, and a rotating shaft is rotatably arranged between the two sets of upright plates 45. One end of the rotating shaft is fixedly connected to a second motor reducer 46.
[0058] When the first motor reducer 42 is working, it drives the active gear 43 at one end to rotate. Through the meshing transmission between the teeth, it drives the driven gear 44 to rotate. The driven gear 44 drives the upper support plate 48 to move synchronously, thereby flexibly adjusting the horizontal rotation angle of the support plate 48.
[0059] In some examples, a drive block 47 is welded to the lower end face of the supporting top plate 48.
[0060] In some examples, the drive block 47 is fixedly mounted on the rotating shaft.
[0061] When the second motor reducer 46 is working, it drives the rotating shaft at one end to rotate. The rotating shaft drives the drive block 47 to rotate synchronously, and the drive block 47 drives the support top plate 48 to rotate synchronously, thereby flexibly adjusting the vertical rotation angle of the support top plate 48.
[0062] By adopting the above technical solution:
[0063] The first motor reducer 42 and the second motor reducer 46 together constitute the driving component of the support platform 4. By controlling the rotation direction and number of rotations of the output shafts of the first motor reducer 42 and the second motor reducer 46, the support angle of the top support plate 48 can be flexibly adjusted. The support angle of the top support plate 48 can be flexibly adjusted according to actual usage requirements to improve the support effect.
[0064] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
