[0058] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0059] Example 1

[0060] like Figure 1-Figure 3 As shown, this embodiment provides a vibration reduction structure, which is arranged on the deck 5 of the ship to carry equipment, and the vibration reduction structure includes a base 1 and an elastic foot 2. The base 1 includes a transverse support plate 11 and at least two vertical support plates 12. The transverse support plate 11 is horizontally arranged, and the vertical support plate 12 is vertically connected to the lower surface of the transverse support plate 11. The vertical support plate 12 is aligned with the vertical main structure 6 of the ship and is used to support the base 1; the elastic foot 2 is arranged on the transverse support plate 11, and the elastic foot 2 is elastic. The vibration reduction structure also includes a first connecting component 3 and a second connecting component 4, wherein the first connecting component 3 is used to connect the elastic foot 2 and the base 8 of the equipment, and the first connecting component 3 does not contact the base 1, and the second connecting component 4 is used to connect the elastic foot 2 and the transverse support plate 11, and the second connecting component 4 does not contact the base 8. By setting a base 1 and an elastic foot 2 in the vibration reduction structure, the vertical support plate 12 of the base 1 is aligned with the vertical main structure 6 of the ship, so that the force of the equipment carried on the vibration reduction structure on the ship mainly acts on the vertical main structure 6 of the ship, which can reduce the vibration of the equipment and avoid deformation of the deck 5 when the equipment is heavy or the vibration of the equipment is serious. At the same time, by setting an elastic foot 2 with elasticity, the equipment can be buffered, the vibration of the equipment can be reduced, and the impact of the vibration of the equipment on the ship can be reduced, equipment damage can be avoided, and the comfort of the living cabin on the ship can be improved. Among them, the elastic base 8 is connected to the base 8 and the base 1 of the equipment respectively through the first connecting component 3 and the second connecting component 4, the first connecting component 3 does not contact the base 1, and the second connecting component 4 does not contact the base 8, so as to avoid the vibration of the equipment being transmitted to the base 1 and the ship through the first connecting component 3 or the second connecting component 4.

[0061] Among them, Figure 2As shown, the vertical main structure 6 of the ship refers to a rigid structure arranged in the vertical direction on the ship in the prior art, including but not limited to a truss 62, a beam 61, etc. on the ship. That is to say, when manufacturing the base 1, the size of the base 1 must be designed and determined according to the weight and size of the mechanical equipment to ensure that the vertical support plate 12 can be aligned with the vertical main structure 6 of the ship.

[0062] Specifically in this embodiment, Figure 1 As shown, the vertical support plate 12 includes a first support plate 121 and a second support plate 122, and the first support plate 121 is vertically connected to the second support plate 122. The horizontal support plate 11 and the vertical support plate 12 are both made of steel plates. By setting the vertical support plate 12 as the first support plate 121 and the second support plate 122 vertically connected to each other, the stability of the base 1 can be improved.

[0063] Among them, according to the size and weight of the equipment that the vibration reduction structure needs to bear, the vertical support plates 12 can be connected into a T-structure, a cross structure or a grid structure as needed, which will not be repeated here.

[0064] Of course, in other embodiments, the vertical support plates 12 may also be arranged in parallel.

[0065] In this embodiment, if Figure 1-Figure 3 As shown, the vertical support plate 12 is in a trapezoidal shape, and the bottom dimension of the vertical support plate 12 is larger than the top dimension of the vertical support plate 12. By setting the bottom dimension of the vertical support plate 12 to be larger than the top dimension, the stability of the base 1 can be improved.

[0066] Of course, in other embodiments, the vertical support plate may also be configured as a rectangle, that is, the top size of the vertical support plate 12 is the same as the bottom size, which will not be described in detail here.

[0067] In this embodiment, there are multiple elastic feet 2, and the multiple elastic feet 2 are arranged on the transverse support plate 11 at intervals. Figure 3 This is only a partial schematic diagram of the vibration reduction structure, and the figure only shows the setting mode of one elastic foot 2. When there are multiple elastic feet 2, the setting mode of multiple elastic feet 2 is exactly the same. By setting multiple elastic feet 2 arranged at intervals, when the equipment is large, the multiple elastic feet 2 provide better support for the equipment and save manufacturing costs.

[0068] Of course, in other embodiments, if the size of the device is not particularly large, an elastic foot 2 having a size comparable to the base 8 of the device may also be provided, which will not be described in detail here.

[0069] In this embodiment, if Figure 3As shown, the elastic foot 2 includes an elastic part 21 and two rigid parts 22, wherein one rigid part 22 is connected to the top of the elastic part 21, and the other rigid part 22 is connected to the bottom of the elastic part 21. The elastic part 21 is made of elastic material, and the rigid part 22 is made of rigid material. By setting the elastic foot 2 to be rigid at the upper and lower ends and elastic in the middle, the connection between the elastic foot 2 and the base 8 and the base 1 is more reliable.

[0070] Of course, in other embodiments, the elastic foot 2 may also be configured to have a structure with only the elastic portion 21 , which will not be described in detail herein.

[0071] Specifically in this embodiment, the first connection assembly 3 includes a first bolt 31 and a first nut 32, a first threaded hole is provided on the elastic foot 2, a first through hole is provided on the base 8, the first bolt 31 is threadedly connected to the elastic foot 2 through the first threaded hole, and the first bolt 31 passes through the first through hole and is threadedly connected to the first nut 32. Similar to the first connection assembly 3, the second connection assembly 4 includes a second bolt 41 and a second nut 42, a second threaded hole is provided on the elastic foot 2, a second through hole is provided on the transverse support plate 11, the second bolt 41 is threadedly connected to the elastic foot 2 through the second threaded hole, and the second bolt 41 passes through the second through hole and is threadedly connected to the second nut 42.

[0072] Of course, the elastic foot 2 can also be connected to the base 8 and the base 1 by using other connecting components in the technology, which will not be repeated here.

[0073] In this embodiment, the vibration reduction structure further includes a web 7, which is disposed between the elastic foot 2 and the transverse support plate 11, and the web 7 is welded to the transverse support plate 11. By providing the web 7, the elastic foot 2 can be separated from the base 1.

[0074] Example 2

[0075] This embodiment provides a method for installing a device, and the method is used to install the vibration reduction structure in the embodiment on the deck of a ship to carry the device, thereby achieving vibration reduction of the device.

[0076] Specifically in this embodiment, the installation method includes the following steps:

[0077] S1: Connect the elastic foot to the equipment, align the vertical support plate with the vertical main structure of the ship, and install the web on the transverse support plate;

[0078] S2: Move the device and the elastic foot to the base;

[0079] S3: Connect the second connecting assembly to the elastic foot, ensuring that the first connecting assembly and the second connecting assembly are both perpendicular to the transverse support plate;

[0080] S31: The web and the base are fixed by spot welding, and then the equipment is lifted until the elastic feet leave the base, and the web and the base are welded together before the equipment is placed back on the transverse support plate.

[0081] S4: After the vibration reduction structure has been under pressure for a period of time, check the pressure of the elastic feet to ensure that the pressure of multiple elastic feet is balanced;

[0082] S5: Connect the second connecting component to the base.

[0083] In step S1, it is necessary to ensure that the elastic foot and the reliable connection part of the base of the device are not loosened. Specifically, the first connection assembly in this embodiment is a bolt and a nut, and the bolt needs to be engaged in place.

[0084] In step S2, the device connected to the elastic foot needs to be safely transferred to the base to avoid collision with obstacles or stairs during the movement. If the device is too large or too heavy, a model or assembly fixture that can accurately reflect the support position of the elastic foot can be made first for positioning so that the device can be accurately placed.

[0085] In step S3, the second bolt is threadedly connected to the equipment base, and after the equipment is moved into place, the verticality of the first bolt and the second bolt is checked, that is, the first bolt and the second bolt are ensured to extend in the vertical direction. If the verticality of the first bolt and the second bolt is not good, necessary adjustments are required.

[0086] In step S31, before welding the web and the base, the device and the elastic base are lifted away from the base to prevent the heat generated by welding from being transferred to the elastic foot and affecting the vibration-isolating effect of the vibration-damping structure.

[0087] In step S4, if the pressure of the elastic foot is uneven, it may be that the connection of the first connecting component or the second connecting component is uneven, which can be adjusted by screwing the first nut or the second nut.

[0088] At the same time, in all steps that require screwing the first connecting component and the second connecting component, after screwing with the screwing tool, attention should be paid to the free rotation degree after screwing to ensure that the first connecting component and the second connecting component will not loosen due to vibration of the equipment.

[0089] Although the specific embodiments of the present invention are described above, it should be understood by those skilled in the art that this is only for illustration and the protection scope of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but these changes and modifications all fall within the protection scope of the present invention.
