Description

Technical Field

[0001] The invention relates to the technical field of ship vibration reduction bases, in particular to an easily replaceable ship single-point vibration reduction base. Background Art

[0002] During the voyage of a ship, due to its special operating environment and operating status, the vibration problem caused by the power equipment is particularly prominent. Unlike land equipment, when a ship is sailing, it is not only stimulated by the power equipment itself, but also continuously affected by external environments such as waves and wind. These factors act together on the hull structure, making the vibration problem more complex and severe.

[0003] First, the vibration of the ship not only reduces the comfort and stealth of the ship, but also may damage the precision equipment and shorten its service life. Especially in high-stress areas, continuous vibration may even damage the hull structure, threatening the safe operation of the ship. These problems usually do not occur in land-based equipment, or the impact is far less than that of ships.

[0004] Secondly, the base structure of the ship power equipment is an important path for vibration transmission, and its design and performance are crucial to the vibration reduction effect of the entire ship. However, due to the limited space and special working environment of the ship, the design of the base structure often faces more stringent challenges than land-based equipment.

[0005] In the prior art, although certain vibration reduction measures are adopted in the composite vibration reduction base for ships disclosed in patent application number CN201410271511.7, some problems still exist. For example, as the overall shape and size of the equipment increase, the weight of the base also increases, making it difficult to carry it by manpower alone, and the welding workload also increases significantly. In addition, when the equipment needs to be replaced, the replacement of the integral base is huge and difficult, which is usually not a major problem in land-based equipment, but has become a significant problem on ships.

[0006] Therefore, in view of the special environment of ships, we propose an easy-to-replace marine single-point vibration reduction base, which aims to solve the problems existing in the existing technology, improve the vibration reduction performance of ship power equipment, and ensure the safety, comfort and stealth of ships. This design not only takes into account the vibration reduction effect, but also fully considers the special working environment and actual needs of ships, which is unmatched by land-based equipment.

[0007] For this reason, we propose an easily replaceable marine single-point vibration-damping base. Summary of the invention

[0014] Furthermore, the pulling and fixing rod includes a longitudinally arranged fixing rod and a transversely arranged fixing rod, which are respectively used to improve the overall rigidity of the vibration-damping base unit in the longitudinal and transverse directions; anchor points are formed at both ends of the pulling and fixing rod, and the anchor points include external threads and clamping nuts arranged at the ends of the rod body, which are used to firmly connect the pulling and fixing rod to the vibration-damping base unit.

[0015] Furthermore, it also includes an adaptive adjustment support device, which includes a trapezoidal boss arranged on the lower side of the base plate and a push block matched with the two waist side inclined surfaces of the trapezoidal boss. The push block and the trapezoidal boss form a wedge structure for realizing the up and down micro-floating adjustment of the vibration damping base unit.

[0016] Furthermore, the adaptive adjustment support device also includes a hydraulic pushing structure, which drives the push block to approach or move away from the trapezoidal boss to achieve smooth up and down movement of the shock absorbing base unit; the hydraulic pushing structure includes a hydraulic oil chamber, a piston body and a piston rod, the piston body is connected to the push block through the piston rod, the piston body slides in the hydraulic oil chamber, dividing the hydraulic oil chamber into a first chamber and a second chamber, and the movement of the push block is achieved by controlling the flow of hydraulic oil.

[0017] Furthermore, connecting pipes are provided between the vibration-damping base units on different sides of the auxiliary equipment base, including a third connecting pipe and a fourth connecting pipe, which are used to connect the first chamber and the second chamber of the vibration-damping base units on different sides to achieve balanced flow of hydraulic oil; wherein, one end of the third connecting pipe is connected to the first connecting pipe on the first balancing side, and the other end is connected to the second connecting pipe on the second balancing side; one end of the fourth connecting pipe is connected to the second connecting pipe on the first balancing side, and the other end is connected to the first connecting pipe on the second balancing side.

These beneficial effects together provide a strong guarantee for the stable operation of ship power equipment, reduce the transmission of vibration and noise, improve the comfort and stealth of the ship, extend the service life of the equipment, and reduce maintenance costs. Therefore, the present invention has broad application prospects and important promotion value in the field of vibration reduction of ship power equipment.

[0020] At the same time, the present invention also has the following advantages: (1) Improve vibration reduction performance and replaceability: The present invention proposes an easily replaceable single-point vibration reduction base for ships, which achieves efficient vibration reduction by optimizing the base structure design. Each vibration reduction base unit can be independently disassembled and assembled, which is convenient for arrangement at various fixing bolt points of the auxiliary equipment base, greatly improving the convenience of replacement. Compared with the traditional integral base, the present invention does not require the replacement of the entire base when the equipment is replaced or repaired. It only needs to replace or repair the damaged single vibration reduction base unit, thereby significantly reducing the engineering workload and cost. In addition, the design of the vibration reduction base unit is ingenious. The combination of a regular rectangular panel and an isosceles trapezoidal web improves the support stability. At the same time, the design of the lightening hole further reduces the overall weight, helps dissipate heat, and improves the comfort and safety of the ship.

[0021] (2) Enhanced structural strength and corrosion resistance: The present invention sets reinforcing ribs inside the vibration-damping base unit, which effectively improves the lateral stiffness and load-bearing performance of the vibration-damping base unit and ensures stable support for auxiliary equipment. The installation openings on the reinforcing ribs facilitate the insertion of bolts and other components, while the U-shaped flow hole design effectively prevents water accumulation inside the vibration-damping base unit, reduces the risk of rust due to immersion, and prolongs its service life. These designs not only enhance the structural strength of the vibration-damping base, but also improve its ability to adapt to harsh marine environments, providing a strong guarantee for the long-term stable operation of ships.

[0022] (3) Achieving adaptive adjustment and balance: The present invention introduces an adaptive adjustment support device, which drives the push block to move through a hydraulic pushing structure, thereby achieving micro-floating adjustment of the vibration-damping base unit up and down. This design enables the vibration-damping base to be adaptively adjusted according to the actual operating status of the auxiliary equipment, effectively balancing the impact of the overturning moment on the equipment and avoiding tilting and damage to the equipment caused by vibration. At the same time, the interconnection and pressure balance of the hydraulic oil chambers on both sides are achieved through a connecting pipe, further improving the stability and safety of the equipment. This adaptive adjustment mechanism is of great significance for improving the vibration reduction performance of ship power equipment, helping to extend the service life of the equipment and reduce maintenance costs.

[0023] (4) Easy installation and maintenance: The vibration-damping base unit of the present invention is simple in design and easy to manufacture and install. During the installation process, it is only necessary to connect the vibration-damping base unit and the auxiliary equipment into a whole and fix it to the hull deck with fasteners such as bolts. At the same time, since each vibration-damping base unit can be disassembled and assembled independently, during maintenance, it is only necessary to operate the damaged or replaced unit without disassembling and reinstalling the entire base. This design not only reduces the difficulty and workload of installation and maintenance, but also improves maintenance efficiency, bringing great convenience to the daily operation and maintenance of the ship.

[0031] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings.

[0032] Embodiment 1 like Figure 1 As shown, this embodiment discloses an easily replaceable marine single-point vibration-damping base, which comprises a panel 1 and a web 2. A vibration-damping pad is laid between the upper end surface of the panel 1 and the auxiliary equipment base. The webs 2 are vertically welded on both sides of the lower end surface of the panel 1. Bolt holes 3 connected with fixing bolts of the auxiliary equipment are provided on the panel 1. The panel 1 and the web 2 are welded to form a vibration-damping base unit 4. Specifically, as shown in FIG. Figure 1As shown, the panel 1 of the vibration-damping base unit 4 is a steel plate in the shape of a regular rectangle. At least two bolt holes 3 are provided on the panel 1, and a lightening hole 5 is provided between the two bolt holes 3. A plurality of anchor bolts for fixing are provided at the bottom of the auxiliary equipment. The lightening holes 5 on the panel 1 in this embodiment are designed and processed according to the positions of the anchor bolts. The bolt holes 3 can be made to correspond to the anchor bolts, and the anchor bolts are passed through the bolt holes 3 to connect the vibration-damping base unit to the equipment to form a whole. It can be understood that a 6JX-type vibration-damping pad is provided between the panel 1 and the base of the auxiliary equipment to form a vibration isolation effect.

[0033] The structure of the web 2 in this embodiment is arranged in an isosceles trapezoidal shape, and has a top edge 6, a bottom edge 7, and a waist 8. The top edge 6 is welded to the lower end surface of the panel 1. The length of the top edge 6 matches the width of the panel 1. The length of the bottom plate 9 is greater than the top edge 6. The enlarged bottom edge 7 increases the contact range and improves the supporting performance; the bottom edge 7 forms a welding edge with the hull deck. In actual use, multiple vibration reduction base units 4 can be set, and each vibration reduction base unit can be independently detachably arranged at each fixing bolt point of the auxiliary equipment base.

[0034] The installation steps in this embodiment are as follows: first, remove the fixing bolts of the vibration-damping pad equipment to be installed so that it is no longer connected to the original base; then use a jack to lift the equipment to separate it from the original base, and cut off the original equipment base; then connect the vibration-damping pad to be installed and the vibration-damping base unit 4 to the equipment as a whole; loosen the jack to directly position and install the equipment on the deck surface; finally, weld the bottom edge 7 of the vibration-damping base unit 4.

[0035] The vibration-damping base unit 4 in this embodiment is cleverly designed. The combination of the regular rectangular panel 1 and the isosceles trapezoidal web 2 not only improves the support stability, but also facilitates installation and removal. The design of the lightening hole 5 not only reduces the overall weight, but also helps to dissipate heat. In addition, the use of the 6JX type vibration-damping pad effectively isolates the vibration transmission between the auxiliary equipment and the hull, improving the comfort and safety of the ship.

[0036] In this embodiment, due to the limited space on the ship and the need to consider the stability and safety of the equipment layout during navigation, the design of the single-point vibration reduction base can more flexibly adapt to the layout requirements of various equipment on the ship, while facilitating installation and replacement. This design may not be common in large-scale land-based equipment, because land-based equipment usually has more space to adopt a more complex vibration reduction system.

[0037] Embodiment 2 like Figure 3 , 5As shown, the difference between this embodiment and the first embodiment is that the vibration reduction base unit 4 in this embodiment also includes a bottom plate 9, the bottom edge 7 of the web 2 is welded to the bottom plate 9, and a reinforcing rib 10 is provided in the rectangular space surrounded by the bottom plate 9, the panel 1, and the web 2. The reinforcing rib 10 can effectively improve the lateral stiffness of the vibration reduction base unit 4, so that the bearing performance and supporting performance of the vibration reduction base unit 4 for the auxiliary equipment are guaranteed; the reinforcing rib 10 is in a rectangular shape that matches the size of the rectangular space, in order to facilitate the panel 1 and the auxiliary equipment base are provided with bolts and other components, and an installation opening 11 is provided between the middle of the upper side of the reinforcing rib 10 and the panel 1; the installation opening 11 allows bolts, nuts and hands to pass through easily, so as to facilitate the bolts to be fixed to the equipment base; a U-shaped flow hole 12 with an opening facing downward is provided on the lower side of the reinforcing rib 10, and the opening side of the U-shaped flow hole 12 contacts the bottom plate 9, so that water will not be retained inside the vibration-damping base unit 4, reducing the risk of the vibration-damping base unit 4 being soaked and corroded.

[0038] In this embodiment, after each independent vibration-damping base unit 4 is replaced and installed, a pulling fixing rod 13 may be provided between two adjacent vibration-damping base units 4. Figure 2-4 As shown, through the subsequent assembly of the pulling and fixing rod 13, the vibration reduction base units 4 installed under the auxiliary equipment base are connected and fixed to form an integral vibration reduction base structure, thereby improving the integrity of the vibration reduction base; specifically, as Figure 3 As shown, the pulling and fixing rod 13 includes a rod body, and the two ends of the rod body are respectively connected to different vibration-damping base units 4, and the two ends of the rod body form anchor points 14. Preferably, the anchor point 14 includes an external thread 15 and a clamping nut 16 arranged at the end of the rod body, and the two vibration-damping base units 4 are connected in the form of threaded nuts to form a connection structure that is easy to adjust the spacing. In addition, at least two clamping nuts 16 are arranged on the external thread 15 of the anchor point 14, and the clamping nuts 16 are respectively arranged on both sides of the plate of the vibration-damping base unit 4. In actual implementation, the anchor points 14 at both ends can also be welded.

[0039] The design of the reinforcing ribs 10 significantly improves the structural strength of the vibration reduction base unit 4. At the same time, the clever arrangement of the installation opening 11 and the U-shaped flow hole 12 not only facilitates the installation operation, but also effectively prevents the problem of internal water accumulation. The introduction of the pulling fixing rod 13 further enhances the connection stability between the vibration reduction base units 4, making the entire vibration reduction system more solid and reliable.

[0040] The pulling fixing rod 13 in this embodiment includes a fixing rod 17 arranged longitudinally, a fixing rod 18 arranged transversely, and a fixing rod 19 arranged longitudinally. Figure 3 , 4As shown, a plurality of vibration-damping base units 4 are arranged along the length direction of the auxiliary equipment base. In this embodiment, three vibration-damping base units 4 are arranged in a row as an example, and two rows are arranged. A longitudinally arranged fixing rod 17 is connected between two vibration-damping base units 4 and the rod body is parallel to the web 2; when installing the pulling fixing rod 13, the reinforcing ribs 10 in the two adjacent vibration-damping base units 4 are provided with fixing holes for the rod body to pass through, and then the clamping nuts 16 are tightened on both sides of the reinforcing ribs 10 respectively, and the tension formed by the pulling fixing rod 13 between the two vibration-damping base units 4 is adjusted, so as to connect the two vibration-damping base units 4 into a whole. In this embodiment, two mutually parallel pulling fixing rods 13 are exemplarily arranged between the two vibration-damping base units 4, and the number of the pulling fixing rods 13 can be increased or decreased according to the situation. The horizontally arranged fixing rod 18 is connected between two vibration-damping base units 4, and the rod body is perpendicular to the web 2; similarly, the horizontally arranged fixing rod 18 is a pulling fixing rod 13 stretched between two rows of vibration-damping base units 4, and its installation method is the same as that of the longitudinally arranged fixing rod 17, except that the two ends of the horizontally arranged fixing rod 18 are fixed in two fixing holes on the web 2. It can be understood that the longitudinally arranged fixing rod can improve the overall longitudinal integrity; the horizontally arranged fixing rod can improve the overall transverse integrity; after the horizontal and longitudinal fixing rods are fixed, the overall rigidity of the vibration-damping base unit 4 can be strengthened; further, the obliquely arranged fixing rod 19 can also be arranged, such as Figure 4 As shown, the obliquely arranged fixing rod 19 is disposed between two vibration-damping base units 4 with asymmetric lateral positions, thereby enhancing the rigidity of the overall lateral oblique direction.

[0041] Embodiment 3 In this embodiment, during the operation of the auxiliary equipment, as the rotating parts operate, a certain overturning moment is formed on the auxiliary equipment, and this moment causes the vibration-damping base units at different positions to bear different pressures. In the prior art, in order to solve the problem of equipment vibration, a spring with a certain damping is usually set at the bottom of the equipment base to form a vibration-damping buffering effect on the auxiliary equipment. However, under the overturning moment, the side of each independently set damping spring that is subject to a larger overturning moment is compressed more, while the other side is compressed less, so that the auxiliary equipment as a whole forms a slight tilt that cannot be detected by the naked eye. This has a greater impact on transmission equipment with high coaxiality requirements.

[0042] As an improvement, it also includes an adaptive adjustment support device, and the lower side of the bottom plate 9 forms an inverted isosceles trapezoidal boss 20, such as Figure 5As shown, a right-angled trapezoidal push block 21 is provided to cooperate with the inclined surfaces on the two waist sides of the trapezoidal boss 20, and the push blocks 21 on both sides move in a mirror image manner, a first inclined surface is formed on both sides of the trapezoidal boss 20, and a second inclined surface matched with it is formed on the push block 21, so that the push blocks 21 on both sides and the trapezoidal boss 20 form a wedge structure 22; in this embodiment, through the sliding contact of the first inclined surface and the second inclined surface, the upper side vibration-damping base unit 4 can be adjusted up and down by a slight amount, and because the two inclined surfaces form the wedge structure 22, the upper side vibration-damping base unit 4 still maintains a high degree of support during the up and down floating process, thereby avoiding repeated elastic vibration of the auxiliary equipment; it can be understood that lubricant can be injected between the inclined surfaces and between the push block 21 and the base plate 9, or a ball structure can be added to reduce a certain friction resistance.

[0043] In this embodiment, an adaptive adjustment support device is provided to adapt to the fact that the ship is affected by external forces such as waves and wind during navigation, which may cause the hull to generate a capsizing moment. This adaptive adjustment support device can automatically adjust the support force according to different force conditions to maintain the stability of the equipment, which is usually not necessary for fixed equipment on land.

[0044] In order to enable the vibration-damping base unit to move up and down smoothly, a hydraulic pushing structure 23 is connected to the side of the push block 21 away from the trapezoidal boss 20, and the hydraulic pushing structure 23 drives the push block 21 to move closer to or away from the trapezoidal boss 20; hydraulic pushing structures are also arranged on the outer sides of the push blocks 21 on both sides, and the two hydraulic pushing structures push the two push blocks 21 to move in a mirror-like manner, so that the floating amount on both sides of the vibration-damping base unit is equal during the up and down floating process to avoid tilting.

[0045] Specifically, the hydraulic pushing structure 23 includes a hydraulic oil chamber 24, a piston body 25, and a piston rod 26. The piston body 25 is slidably disposed in the hydraulic oil chamber 24. Figure 6 As shown, the piston body 25 is connected to the push block 21 through the piston rod 26 through the hydraulic oil chamber 24. The moving direction of the piston body 25 is the same as that of the push block 21. The piston body 25 divides the hydraulic oil chamber 24 into a first chamber 27 close to the trapezoidal boss 20 and a second chamber 28 away from the trapezoidal boss 20. The first chamber 27 is provided with a first oil port 29, and the second chamber 28 is provided with a second oil port 30. In order to make the push blocks 21 on both sides form a mirror movement, the first oil ports 29 between the hydraulic squeezing and pushing structures on both sides of the vibration reduction base unit 4 are connected through a first connecting pipe 31, and the second oil ports 30 are connected through a second connecting pipe 32. In actual use, when the hydraulic oil flows into the first connecting pipe 31, it can be diverted to the first chambers 27 on both sides at the same time, so that the push blocks 21 on both sides are pushed away at the same time, and then the vibration reduction base unit 4 forms a certain downward movement; conversely, the hydraulic oil can also flow into the second connecting pipe 32, and the vibration reduction base unit will move upward to a certain extent. Furthermore, one side of the auxiliary equipment base forms a first balancing side 33, and the other side forms a second balancing side 34. In actual use, the different force-bearing sides formed by the auxiliary equipment under the overturning moment are divided into the first balancing side 33 and the second balancing side 34, and the hydraulic oil chambers 24 on both sides are connected according to a certain design. Specifically, Figure 6 As shown, a third connecting tube 35 and a fourth connecting tube 36 are provided between the vibration damping base units 4 on different sides of the first balancing side 33 and the second balancing side 34. One end of the third connecting tube 35 is connected to the first connecting tube 31 on the first balancing side 33, and the other end is connected to the second connecting tube 32 on the second balancing side 34; one end of the fourth connecting tube 36 is connected to the second connecting tube 32 on the first balancing side 33, and the other end is connected to the first connecting tube 31 on the second balancing side 34. In actual use, the hydraulic oil chamber 24 and the first, second, third and fourth connecting pipes are filled with hydraulic oil and form a certain pressure. When the first balancing side 33 is subjected to a large pressure under the overturning moment, under the downward pressure trend of the trapezoidal boss 20 on this side, the push blocks 21 on both sides tend to move outward, thereby squeezing the second chamber 28 in the first balancing side 33. In fact, the internal oil pressure increases and is connected to the first chamber 27 in the second balancing side 34 through the fourth connecting pipe 36, so that the internal oil pressure increases, so that the two push blocks 21 in the second balancing side 34 tend to move away from each other, and then the vibration reduction base unit on the second balancing side 34 tends to descend, so that the first balancing side 33 and the second balancing side 34 can automatically adjust the balance under the overturning moment, and vice versa; the above principle can also be applied to the occurrence of unbalanced vibration of the equipment, thereby forming a better shock-absorbing and balancing effect.

[0046] Through the ingenious design of the third connecting pipe 35 and the fourth connecting pipe 36, the mutual connection and pressure balance of the hydraulic oil chambers on both sides are achieved, so that the auxiliary equipment can automatically perform balance adjustment under the action of the overturning moment. This design not only improves the stability of the equipment, but also effectively extends the service life of the equipment and reduces damage and maintenance costs caused by vibration.

[0047] Furthermore, it also includes a travel limit structure 37, which is used to limit the up and down floating travel of the vibration reduction base unit by forming a limit structure. Specifically, Figure 5 As shown, a longitudinal through hole 38 is provided at the center of the trapezoidal boss 20, and a guide rod 39 is vertically provided on the base plate. The base plate is actually fixed on the foundation of the hull deck. Multiple guide rods 39 can be provided. This embodiment takes one as an example. The guide rod 39 passes through the through hole 38 and is slidably connected thereto. The guide rod 39 passes upward through the upper end of the trapezoidal boss 20 and is provided with a limiting thread 40, which is threadedly connected to an adjusting nut 41; by rotating the adjusting nut 41, its position on the limiting thread 40 is changed, thereby limiting the travel range of the vibration damping base unit.

[0048] The introduction of the travel limit structure 37 effectively limits the up and down floating travel of the vibration reduction base unit, avoiding equipment damage or safety hazards caused by excessive floating. At the same time, by adjusting the rotation of the nut 41, the travel range can be easily adjusted to meet the needs of different usage scenarios, especially when ships encounter various unforeseen external forces during navigation. The travel limit structure can ensure that the up and down floating of the vibration reduction base in extreme cases will not exceed the safety range, thereby protecting the equipment and hull structure. It is generally only used in marine environments.

[0049] A supporting elastic member 42 is provided between the lower end surface of the trapezoidal boss 20 and the base plate. In this embodiment, the supporting elastic member 42 includes a plurality of disc springs, which are sleeved on the guide rod 39, and vibration-damping pads are provided on both the upper and lower sides of the plurality of disc springs. The disc spring has the advantages of good support and small space occupation, which facilitates the arrangement of the supporting elastic member 42.

[0050] The design of the supporting elastic member 42 not only provides additional support for the vibration-damping base unit, but also helps to absorb and disperse vibration energy, further improving the stability and safety of the device. The use of multiple disc springs enables the supporting elastic member 42 to evenly distribute force when under pressure, avoiding local overload.
