Description

Technical Field

[0001] This utility model relates to the field of vibration damping equipment technology, and in particular to a vibration damping structure and a high-pressure spray device for a ship loader. Background Technology

[0002] The piping of the high-pressure spray system for port ship loaders needs to withstand 1.5 MPa of high pressure from vibration-damping structures. Furthermore, the maximum movement of the ship loader's boom reaches 15 meters. During boom movement, the piping is prone to severe vibration due to rigid connections, leading to loosening and leakage at pipe joints. Simultaneously, the average annual humidity in the Yangtze River basin is 75%, and ordinary steel pipes exposed for extended periods are susceptible to corrosion, affecting the stability of high-pressure fluid transport and increasing equipment maintenance costs. Existing piping systems mostly use fixed, rigid connections, lacking targeted vibration-damping structures, and corrosion protection relies solely on surface painting, making the high-pressure spray system unsuitable for the harsh environment of high humidity and high dust levels in ports. Utility Model Content

[0003] In view of the technical problems existing in the above-mentioned vibration-damping structures, the first technical solution of this utility model is proposed.

[0004] This utility model provides a vibration-damping structure, the purpose of which is to solve the technical problem that existing pipelines mostly use fixed hard connections and lack targeted vibration-damping structures.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a vibration damping structure, comprising a vibration damping component, including a high-pressure pipeline and a corrugated pipe disposed outside the high-pressure pipeline, the corrugated pipe being connected to the high-pressure pipeline via a flange; and, The auxiliary component includes a guide tube disposed outside the high-pressure pipeline, the guide tube being fixed to the high-pressure pipeline by a pipe clamp.

[0006] As a preferred embodiment of the vibration-damping structure of this utility model, the auxiliary components further include a clamp disposed on the outside of the high-pressure pipeline, and multiple sets of spring shock absorbers disposed below the clamp.

[0007] As a preferred embodiment of the vibration damping structure of this utility model, the spring damper is disposed on the buffer seat.

[0008] As a preferred embodiment of the vibration-damping structure of this utility model, the buffer seat is fixed to the support seat by expansion screws.

[0009] As a preferred embodiment of the vibration-damping structure of this utility model, a sealing gasket is installed on the inner side of the flange.

[0010] As a preferred embodiment of the vibration-damping structure of this utility model, the high-pressure pipeline is coated with an 80μm polyvinyl fluoride coating on its outer side.

[0011] The beneficial effects of the vibration-damping structure of this utility model are as follows: By installing a bellows on the flange, the sealing gasket on the inner side of the flange can absorb the lateral and longitudinal vibrations generated when the high-pressure pipeline moves, avoiding vibration transmission that could damage the pipeline or connection parts; at the same time, a guide pipe is installed on the high-pressure pipeline, and the guide pipe is connected to the outside of the high-pressure pipeline through a pipe clamp to guide the moving high-pressure pipeline, ensuring that it moves in a preset direction and avoiding twisting and deformation caused by disordered shaking; the high-pressure pipeline is coated with an 80μm polyvinyl fluoride coating on the outside, which effectively prevents corrosion and damage to the outer wall of the high-pressure pipeline, and also reduces the frictional resistance between the high-pressure pipeline and the pipe clamp and guide pipe, reducing wear during long-term use and extending the service life of the pipeline.

[0012] Another objective of this invention is to provide a high-pressure spray device for ship loaders, which aims to solve the problem that existing high-pressure spray devices for ship loaders cannot adapt to the harsh environment of high humidity and high dust in ports.

[0013] To solve the above-mentioned technical problems, the present invention also provides the following technical solution: a high-pressure spray device for a ship loader, comprising a vibration damping structure; and a protective component comprising a high-pressure plunger pump connected to the high-pressure pipeline through the guide tube, and a protective cover fitted on the outside of the high-pressure plunger pump.

[0014] As a preferred embodiment of the high-pressure spray device for the ship loader of this utility model, the protective cover has ventilation openings on its side.

[0015] As a preferred embodiment of the high-pressure spray device for the ship loader of this utility model, the protective cover is equipped with a rainproof canopy on top.

[0016] As a preferred embodiment of the high-pressure spray device for the ship loader of this utility model, the protective cover is provided with a drainage hole at the bottom.

[0017] The beneficial effects of the high-pressure spray device for ship loaders of this utility model are as follows: the protective cover can directly block the dust at the dock, effectively preventing the high-pressure plunger pump from getting stuck and worn due to dust accumulation. At the same time, in conjunction with the rainproof canopy and drainage holes, it can isolate rainwater and water vapor, solving the problems of components getting damp and rusting and circuit short circuits in high humidity environments.

[0018] One end of the guide tube is fixed to the high-pressure pipeline by a pipe clamp, and the other end is fixed to the protective cover. This can reduce the impact of pipeline vibration on the high-pressure plunger pump. This solution, through active protection design, not only relies on the weather resistance of the components themselves, but also blocks the contact path of dust and water vapor from the source through structures such as protective covers, rain shelters, and drainage holes. At the same time, combined with anti-vibration and heat dissipation design, it forms a comprehensive protection solution. Attached Figure Description

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0025] Example 1 Reference Figures 1-3 This is the first embodiment of the present invention, which provides a vibration damping structure, including a vibration damping component 1, comprising a high-pressure pipeline 11 and a corrugated pipe 12 disposed outside the high-pressure pipeline 11. The corrugated pipe 12, through its own deformation, provides a reserve distance for the high-pressure pipeline 11 to move, absorbs pipeline vibration, reduces the transmission of vibration to other connecting components, and prevents rigid tension caused by restricted pipeline movement. The corrugated pipe 12 is connected to the high-pressure pipeline 11 via a flange 13, ensuring that the corrugated pipe 12 and the high-pressure pipeline 11 move synchronously, preventing them from separating and causing vibration damping failure, while also ensuring the sealing of the pipeline connection to prevent fluid leakage within the high-pressure pipeline 11; and... Auxiliary component 2 includes a guide tube 21 disposed on the outside of the high-pressure pipeline 11. The guide tube 21 is fixed to the high-pressure pipeline 11 by a pipe clamp 22. The guide tube 21 is fitted on the outside of the high-pressure pipeline 11 and forms a fixed moving channel after being fixed by the pipe clamp 22. When the high-pressure pipeline 11 is displaced due to vibration, the guide tube 21 will restrict it to move only in a preset direction, so as to avoid disorderly shaking or twisting of the high-pressure pipeline 11 and prevent problems such as cracking and interface leakage of the high-pressure pipeline 11. Especially under high-pressure conditions, it can reduce fatigue damage caused by excessive force on a single point of the high-pressure pipeline 11, thereby extending the overall service life of the pipeline. The auxiliary component 2 complements the vibration damping component 1. The vibration damping component 1 allows the pipeline to move within a certain range to offset the vibration energy, while the auxiliary component 2 allows the pipeline to move while limiting its direction of movement through the guide tube 21, so as to prevent the displacement caused by the vibration damping component 1 from causing the high-pressure pipeline 11 to go out of control.

[0026] Preferably, the auxiliary component 2 also includes a clamp 23 disposed on the outside of the high-pressure pipeline 11, and multiple sets of spring shock absorbers 24 disposed below the clamp 23. The clamp 23 is directly fitted on the outside of the high-pressure pipeline 11, which can provide uniform clamping force from the circumference of the high-pressure pipeline 11, reduce local deformation of the pipeline caused by uneven force, and prevent sagging and shaking in the middle section of the high-pressure pipeline 11. The spring shock absorbers 24 absorb the vibration energy of the high-pressure pipeline 11 through the extension and contraction of the spring shock absorbers 24, thereby achieving secondary vibration protection.

[0027] Furthermore, the spring damper 24 is mounted on the buffer seat 25, making the force-bearing surface of the spring damper 24 flat and stable, ensuring that the spring damper 24 always extends and retracts in the preset direction after being subjected to external force, thus maximizing the effect of secondary vibration reduction. The buffer seat 25 is fixed to the support seat 27 by the expansion screw 26 to resist the reaction force generated when the high pressure pipeline 11 vibrates, and to prevent the buffer seat 25 from loosening or shifting.

[0028] During use: fluid enters the high-pressure pipeline 11. One end of the high-pressure pipeline 11 is fixedly connected to the guide pipe 21 through the pipe clamp 22, so that the high-pressure pipeline 11 extends in a preset direction. When the high-pressure pipeline 11 is affected by the external environment or the internal fluid transport causes vibration, the bellows 12 expands and contracts to absorb part of the force. At this time, the high-pressure pipeline 11 undergoes a small displacement to dissipate the vibration force. The guide pipe 21 controls the displacement of the high-pressure pipeline 11 to avoid the high-pressure pipeline 11 moving out of control due to disorder. At the same time, the spring shock absorber 24 achieves secondary absorption of the vibration force, further weakening the impact of vibration on the device and achieving dual protection.

[0029] Example 2 Reference Figures 1-3This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that a sealing gasket 14 is added to the inner side of the flange 13 to absorb the lateral and longitudinal vibrations generated when the boom moves, to prevent the bellows 12 from detaching from the high-pressure pipeline 11 when it expands and contracts to reduce vibration, and to improve the stability of the device.

[0030] Preferably, the outer side of the high-pressure pipeline 11 is coated with an 80μm polyvinyl fluoride coating to resist corrosion in high humidity environments.

[0031] When the bellows 12 absorbs part of the vibration force, the high-pressure pipeline 11 will undergo a small displacement. At this time, the sealing gasket 14 inside the flange 13 will act synchronously, absorbing the remaining lateral and longitudinal vibrations on the one hand, and tightly fitting the flange 13 and the pipeline on the other hand, preventing the bellows 12 from separating from the high-pressure pipeline 11 when it expands and contracts. Meanwhile, the polyvinyl fluoride coating continuously isolates moisture, prevents corrosion of the outer wall of the high-pressure pipeline 11, ensures stable fluid transport throughout the process, and reduces the friction between the high-pressure pipeline 11 and the pipe clamp 22 and clamp 23, thus extending the service life of the device.

[0032] Example 3 Reference Figures 1-3 This is the third embodiment of the present invention. This embodiment further provides a high-pressure spray device for a ship loader, including the anti-vibration structure in the above embodiment, and also includes a protective component 3, including a high-pressure plunger pump 31 connected to the high-pressure pipeline 11 through a guide pipe 21, and a 304 stainless steel protective cover 32 with a thickness of 2mm fitted on the outside of the high-pressure plunger pump 31. This directly blocks dust, rainwater, and salt spray in the port environment, preventing impurities from entering the pump body and causing internal wear and jamming, or water vapor causing short circuits and component corrosion, thus extending the service life of the pump body.

[0033] The protective cover 32 has ventilation openings 33 on its side, with a ventilation area of ​​30% of the side area, to achieve heat dissipation. The top of the protective cover 32 is equipped with a rainproof canopy 34, and the bottom of the protective cover 32 is provided with drainage holes 35 to prevent rainwater and dust from directly contacting the pump body.

[0034] During use: The high-pressure plunger pump 31 is directly connected to the high-pressure pipeline 11. Fluid flows from the high-pressure plunger pump 31 into the high-pressure pipeline 11. The high-pressure pipeline 11 is fixed to the protective cover 32 by the pipe clamp 22, providing basic force for guidance. When it rains or the air humidity is particularly high, the rainproof canopy 34 on the top of the protective cover 32 prevents rainwater from directly contacting the high-pressure plunger pump 31. When water vapor enters the interior of the protective cover 32, the heat generated by the high-pressure plunger pump 31 during operation can also evaporate the water vapor and flow into the protective cover 32 through the drain hole 35. At the same time, the vent 33 helps the high-pressure plunger pump 31 to continuously dissipate heat, improving the stability of the device.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
