[0032] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] Example 1

[0034] In the existing technology, due to the complexity of the actual working conditions of ship navigation, the installed sealing rubber 4 is constantly changing due to the swaying of the ship. It is difficult to measure the size information of the sealing rubber 4 at different spatial positions, resulting in large measurement errors and low measurement accuracy.

[0035] To address the aforementioned technical problems, this invention proposes a multi-degree-of-freedom structure measuring device for the sealing rubber of a liquid tank gas chamber, such as... Figures 1-4 As shown, the multi-degree-of-freedom structural measuring device is used to measure the installation height H and bending depth D of the sealing rubber 4 at different spatial positions. The multi-degree-of-freedom structural measuring device includes a base 1, a top plate 2, and a lead screw assembly 3. The base 1 and top plate 2 are horizontally arranged and vertically mounted on the lead screw assembly 3. The top plate 2 is positioned above the base 1, and a support member 12 is provided on the base 1. The top plate 2 is slidably connected to the lead screw assembly 3, and the top plate 2 can move vertically along the lead screw assembly 3. The sealing rubber 4 is C-shaped and installed in the multi-degree-of-freedom structural measuring device. The lower end of the sealing rubber 4 is slidably connected to the base 1, and the upper end of the sealing rubber 4 is slidably connected to the top plate 2. The lower end of the sealing rubber 4 can move horizontally along the base 1, and the upper end of the sealing rubber 4 can move horizontally along the top plate 2.

[0036] The multi-degree-of-freedom structure measuring device described in this embodiment has the following advantages:

[0037] I. The multi-degree-of-freedom structural measuring device described in this embodiment has three degrees of freedom: the top plate 2 can move vertically along the lead screw assembly 3, the lower end of the sealing rubber 4 can move horizontally along the base 1, and the upper end of the sealing rubber 4 can move horizontally along the top plate 2. Through these three degrees of freedom, the multi-degree-of-freedom structural measuring device can simulate various installation conditions of the sealing rubber 4 during ship navigation. On the one hand, operators can easily adjust the position and state of the sealing rubber 4 and manually measure the installation height H and bending depth D of the sealing rubber 4 at different spatial positions. Measuring the dimensional information of the sealing rubber 4 at different spatial positions is easy, greatly simplifying the measurement workflow and improving measurement efficiency. On the other hand, the measurement data error is small, and the measurement data accuracy is high.

[0038] Second, in the multi-degree-of-freedom structural measuring device described in this embodiment, the base 1 and the top plate 2 are horizontally arranged and vertically mounted on the lead screw assembly 3. This structural design ensures the overall stability of the multi-degree-of-freedom structural measuring device.

[0039] Third, the multi-degree-of-freedom structural measuring device described in this embodiment has a support member 12 set below the base 1. On the one hand, it provides space for the lower end of the sealing rubber 4 to move horizontally along the base 1; on the other hand, it provides installation space for the base 1 to be installed on the lead screw assembly 3. In addition, it further improves the overall stability of the multi-degree-of-freedom structural measuring device.

[0040] More specifically, the lower end of the sealing rubber 4 is detachably connected to the base 1, and the upper end of the sealing rubber 4 is detachably connected to the top plate 2; this facilitates the installation and removal of the sealing rubber 4, greatly saves installation and removal time, and improves the efficiency of measurement work.

[0041] Specifically, the multi-degree-of-freedom structure measuring device further includes a lower connecting component 41 and an upper connecting component 42. The lower end of the sealing rubber 4 is fixedly connected to the lower connecting component 41, and the lower connecting component 41 is slidably connected to the base 1. The upper end of the sealing rubber 4 is fixedly connected to the upper connecting component 42, and the upper connecting component 42 is slidably connected to the top plate 2.

[0042] This setup has the following advantages:

[0043] The lower connecting component 41 and the upper connecting component 42 enhance the stability and reliability of the connection, ensuring that the sealing rubber 4 maintains a stable connection during the measurement process, thereby guaranteeing the smooth progress of the measurement work.

[0044] Second, the lower connecting component 41 and the upper connecting component 42 provide a stable reference for the measurement of the sealing rubber 4. When measuring the installation height H and bending depth D of the sealing rubber 4, accurate connection and stable reference can ensure that the starting point of the measurement data is accurate, thereby reducing measurement errors and improving the accuracy and reliability of the measurement data.

[0045] Third, the lower connecting component 41 is slidably connected to the base 1, and the upper connecting component 42 is slidably connected to the top plate 2, allowing the upper and lower ends of the sealing rubber 4 to move flexibly in the horizontal direction. Operators can easily adjust the position and state of the sealing rubber 4 according to actual measurement needs, achieving accurate measurement of the sealing rubber 4 at different spatial locations, further simplifying the measurement operation process.

[0046] Specifically, a first movable slide groove 11 is provided on the base 1, and the lower connecting component 41 is slidably connected to the first movable slide groove 11. A second movable slide groove 21 is provided on the top plate 2, and the upper connecting component 42 is slidably connected to the second movable slide groove 21.

[0047] This design has several significant advantages, as follows:

[0048] First, the first moving slide 11 and the second moving slide 21 provide precise tracks for the movement of the lower connecting assembly 41 and the upper connecting assembly 42. The operator can accurately move the sealing rubber 4 to the desired position along the set path of the slide, thereby achieving precise adjustment of the horizontal position of the sealing rubber 4. This is crucial for measuring the installation height H and bending depth D of the sealing rubber 4 at different spatial positions, ensuring the accuracy of the measurement data and meeting the requirements of high-precision measurement.

[0049] Second, the first moving slide 11 and the second moving slide 21 provide a clear guiding direction for the movement of the lower connecting assembly 41 and the upper connecting assembly 42, avoiding swaying and offset caused by irregular movement. This helps maintain the stability of the sealing rubber 4 during movement.

[0050] Third, the operator only needs to push the lower connecting component 41 and the upper connecting component 42 along the first moving slide 11 and the second moving slide 21 to quickly adjust the position of the sealing rubber 4. The moving operation is simpler and more intuitive, which greatly saves the time required to adjust the position of the sealing rubber 4 and improves the efficiency of the measurement work.

[0051] Specifically, such as Figure 1 and Figure 2As shown, the lower connecting assembly 41 includes a first connecting member 411, a first pad 412, and a first protective rubber 413. The first protective rubber 413 is disposed between the first pad 412 and the sealing rubber 4. The first protective rubber 413 can buffer and reduce friction, preventing the first pad 412 from directly rubbing against the sealing rubber 4, reducing wear on the lower end of the sealing rubber 4, and extending the service life of the sealing rubber 4. At the same time, the first protective rubber 413 has a certain degree of corrosion resistance, which can isolate the sealing rubber 4 from contact with other potentially corrosive components or environmental factors, ensuring its long-term stable use.

[0052] The first connector 411 passes sequentially through the first pad 412, the first protective rubber 413, the sealing rubber 4, and the base 1, connecting the sealing rubber 4 to the base 1. The first connector 411 is also slidably connected to the first movable slide groove 11. This multi-layered connection increases the strength and stability of the connection, preventing the sealing rubber 4 from easily loosening or falling off during measurement, thus ensuring the smooth progress of the measurement work.

[0053] Specifically, such as Figure 1 and Figure 2 As shown, the upper connecting assembly 42 includes a second connector 421, a second pad 422, a second protective rubber 423, an upper clamping plate 424, and a third connector 425. The upper clamping plate 424 is used to simulate the upper deck of a liquid cargo transport ship, and can better simulate various installation conditions of the sealing rubber 4 during ship navigation, resulting in high accuracy of measurement data.

[0054] The second protective rubber 423 is disposed between the second pad 422 and the sealing rubber 4, and the second protective rubber 423 can play a role in buffering and reducing friction. It can prevent the second pad 422 from directly rubbing against the sealing rubber 4, reduce wear on the upper end of the sealing rubber 4, and extend the service life of the sealing rubber 4. At the same time, the second protective rubber 423 has a certain degree of anti-corrosion performance, which can isolate the sealing rubber 4 from contact with other potentially corrosive components or environmental factors, ensuring its long-term stable use.

[0055] The upper clamping plate 424 is disposed between the sealing rubber 4 and the top plate 2. The third connecting piece 425 passes through the second pad 422, the second protective rubber 423, the sealing rubber 4, and the upper clamping plate 424 in sequence to connect and fix the sealing rubber 4 to the upper clamping plate 424. The second connecting piece 421 passes through the second pad 422, the second protective rubber 423, the sealing rubber 4, the upper clamping plate 424, and the top plate 2 in sequence to connect the sealing rubber 4 to the top plate 2. The second connecting piece 421 is slidably connected to the second movable slide groove 21.

[0056] This dual-connection design makes the connection between the upper end of the sealing rubber 4 and the top plate 2 more stable, and can withstand various external forces during the measurement process. It ensures that the sealing rubber 4 remains stable during movement and measurement. When measuring the installation height H and bending depth D of the sealing rubber 4, it can reduce measurement errors and make the measurement data more accurately reflect the actual size and condition of the sealing rubber 4.

[0072] Furthermore, the number of the first connectors 411 is not specifically limited.

[0073] Preferably, in this embodiment, the number of the first connectors 411 is two. The number of the first connectors 411 is the same as the number of the first movable slides 11.

[0074] Furthermore, the number of the third connector 425 is not specifically limited.

[0075] Preferably, the number of the third connectors 425 is set to two, and the two third connectors 425 are symmetrically arranged on both sides of the second moving slide 21.

[0076] This design improves the connection balance and stability at the upper end of the sealing rubber 4.

[0077] Furthermore, the number of the second connector 421 is not specifically limited. The number of the second connector 421 can be one, or the number of the second connector 421 can be two, and it is not limited to this.

[0078] Preferably, in this embodiment, the number of the second connector 421 is two.

[0079] like Figure 1 As shown, both of the second connecting members 421 are disposed in a second movable slide groove 21.

[0080] This design improves the stability of movement at the upper end of the sealing rubber 4.

[0081] like Figure 1 and Figure 3 As shown, the two second connectors 421 are symmetrically arranged on both sides of the line connecting the two third connectors 425.

[0082] This design improves the balance and stability of the upper part of the sealing rubber 4.

[0083] Specifically, the support member 12 is detachably connected to the base 1.

[0084] This design facilitates the installation and removal of the support member 12.

[0085] Specifically, the support member 12 is detachably connected to the base 1 via a third connecting component 13.

[0086] This design ensures both a stable structural connection and facilitates quick installation and disassembly.

[0087] Specifically, a first connecting component 301 and a second connecting component 302 are installed on the lead screw assembly 3. The base 1 is connected to the lead screw assembly 3 through the first connecting component 301, and the top plate 2 is connected to the lead screw assembly 3 through the second connecting component 302.

[0088] This setup ensures a stable structural connection while facilitating the independent lifting and lowering of the top plate 2 along the screw assembly 3, allowing for quick adaptation to the measurement needs of sealing rubber 4 at different heights.

[0089] Specifically, the lead screw assembly 3 includes a first lead screw 31 and a second lead screw 32, which are symmetrically installed on both sides of the base 1 and the top plate 2.

[0090] This configuration enhances structural stability on the one hand; on the other hand, the first lead screw 31 and the second lead screw 32 ensure that the top plate 2 maintains a uniform speed and stable posture during the rising or falling process, thereby ensuring the accuracy of processing or measurement.

[0091] Furthermore, the first connecting component 301, the second connecting component 302, and the third connecting component 13 are not specifically limited.

[0092] Specifically, the first connecting component 301, the second connecting component 302, and the third connecting component 13 are nut assemblies.

[0094] This invention enables the sealing rubber 4 to move horizontally and vertically, and allows for the measurement of the side cross-sectional structural dimensions of the sealing rubber 4 when it is in a fixed position, thereby improving the accuracy and convenience of the measurement work.
