Technical Field

[0001] The utility model relates to the technical field of ship outfitting, in particular to a vibration reduction and noise reduction device for ship outfitting. Background Art

[0002] Ship outfitting refers to the installation of machinery, electrical and electronic equipment after the main structure of the hull is built and the ship is launched. Ship outfitting refers to everything on the ship except the hull and ship power unit. A shock-absorbing mounting platform can be used during ship outfitting.

[0003] However, most of the ship outfitting shock-absorbing platforms on the market still have some shortcomings. For example, most of the existing ship outfitting shock-absorbing platforms are prone to friction noise during use, which is not conducive to effective noise reduction, and the shock absorption effect is general, and it is difficult to provide a good buffering and protective effect for the installation structure, and thus there are certain usage defects. Therefore, we propose a shock-absorbing and noise reduction device for ship outfitting to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of the utility model is to provide a shock-absorbing and noise-reducing device for ship outfitting, so as to solve the problem that the existing ship outfitting shock-absorbing platforms proposed in the above background technology are mostly prone to friction noise when in use, are not convenient for effective noise reduction, and have a general shock-absorbing effect, and are difficult to provide a good buffering and protective effect on the installation structure.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution: a vibration reduction and noise reduction device for ship outfitting, comprising:

[0006] A mounting seat, wherein a mounting cavity is provided inside the mounting seat, a piston is provided inside the mounting cavity, a through-hole structure is provided inside the piston, a movable component is connected inside the through-hole structure, and the movable component includes a plug, a connecting rod and a baffle;

[0007] A connecting tube is opened inside the mounting seat, an air cavity is arranged inside the connecting tube, the upper end of the piston is fixedly connected to a support rod, the upper end of the support rod is fixedly connected to a mounting platform, a mounting hole is opened inside the mounting platform, and a spring is fixedly connected to the lower end surface of the mounting platform.

[0008] Preferably, the installation cavity is arranged bilaterally symmetrically with respect to a vertical center line of the installation seat, and the connecting pipe is connected between the monomers of the installation cavity.

[0009] Preferably, a "U"-shaped protruding structure is provided in the middle of the connecting pipe, and the air cavity is located inside the protruding structure.

[0010] Preferably, the through hole structure includes a first connecting hole and a second connecting hole, the first connecting hole is opened inside the piston, and the lower end of the first connecting hole is connected to the second connecting hole.

[0011] Preferably, the vertical cross-section of the first connecting hole is trapezoidal, and the first connecting hole and the second connecting hole are both symmetrically arranged about the vertical center line of the piston.

[0012] Preferably, the lower end of the plug on the left side of the support rod is fixedly connected to a connecting rod, and the upper end of the plug on the right side of the support rod is fixedly connected to a connecting rod, the lower end of the connecting rod on the left side of the support rod is fixedly connected to a baffle, and the upper end of the connecting rod on the right side of the support rod is fixedly connected to a baffle.

[0013] Preferably, the vertical cross-section of the plug is trapezoidal, and the connecting rod at the outer end of the plug is slidably connected to the piston through the second connecting hole.

[0014] Preferably, the support rod is slidably connected to the mounting seat, and the support rod is symmetrically arranged with respect to the vertical center line of the mounting plate, and the spring is evenly distributed between the mounting plate and the mounting seat.

[0015] Compared with the prior art, the utility model has the following beneficial effects: the vibration reduction and noise reduction device for ship outfitting solves the problem that the existing ship outfitting vibration reduction platform is prone to generate friction noise when in use, is not convenient for effective noise reduction, and has a general vibration reduction effect, and is difficult to provide a good buffering and protective effect on the installation structure;

[0016] It is equipped with an installation cavity, a connecting pipe and an air cavity. The damping effect generated by the oil in the installation cavity and the gas in the connecting pipe and the air cavity plays a role in shock absorption and buffering. At the same time, the oil absorbs kinetic energy and converts it into heat energy, which can effectively reduce friction noise and achieve noise reduction effect.

[0017] It is provided with a support rod, a piston and a movable component. The outfitting components are fixedly installed on the upper end of the mounting plate through the mounting holes. When the equipment vibrates during operation and the mounting plate is under pressure, the mounting plate presses down the spring, so that the support rod drives the piston to move downward inside the mounting cavity. As the hydraulic pressure under the piston increases, the oil under the piston flows to the top of the piston through the through-hole structure. At the same time, the movable component moves upward inside the through-hole structure under the pressure, and the damping effect generated by the oil plays a shock-absorbing and buffering role, and the shock-absorbing effect is better.

[0018] A spring, a mounting plate and a support rod are provided. The spring is fixedly connected to the lower end surface of the mounting plate and is evenly distributed between the mounting plate and the mounting seat. Since the support rod and the mounting seat form a sliding connection, the vibration is buffered by the spring. At the same time, the support rod drives the piston to move and reduce the vibration, thereby effectively protecting the mounting plate and outfitting equipment and making it more practical.

Since the support rod 9 and the mounting seat 1 form a sliding connection, and the support rod 9 is symmetrically arranged about the vertical center line of the mounting plate 10, the mounting plate 10 is provided with a movable support by the support rod 9 and the spring 12;

When the equipment generates vibration during operation and the mounting plate 10 is under pressure, the mounting plate 10 presses down the spring 12, so that the support rod 9 drives the piston 5 to move downward inside the mounting cavity 2. Due to the increase in hydraulic pressure under the piston 5, the oil under the piston 5 flows to the top of the piston 5 through the through-hole structure.
