Description

Technical Field

[0001] The invention relates to the technical field of ships, and in particular to a novel anti-vibration structure of a driving cab. Background Art

[0002] The vibration performance of the superstructure is the main part of the ship's vibration performance, and the vibration control of the compass deck is the key and difficult point in the superstructure vibration control. It is common to find that the vibration of the compass deck exceeds the standard in the vibration assessment of the actual ship design. When the vibration risk is found in the vibration calculation or the vibration problem is found in the vibration measurement, anti-vibration measures are generally required.

[0003] Common anti-vibration measures are as follows:

[0004] (1) Increasing the size of the compass deck components, such as increasing the deck plating thickness or adding deck transverse beams;

[0005] (2) Additional pillars or structural bulkheads are installed under the compass deck. The additional pillars or structural bulkheads must be coordinated with the layout of the navigation bridge;

[0006] (3) Add a main engine balance block to actively reduce the vibration output of the vibration source.

[0007] The shortcomings of the existing anti-vibration measures are analyzed in detail as follows:

[0008] (1) Increasing the size of the compass deck components has the disadvantages of poor effectiveness and a significant increase in weight.

[0009] (2) Adding pillars or structural bulkheads is more effective for the vertical vibration in the middle of the compass deck, but it will affect the layout of the navigation deck. At the same time, the most serious vibration of the closed bridge is usually at the two wings of the compass deck, which generally appears in the form of horizontal torsional vibration. Adding pillars or bulkheads is difficult to solve the vibration problem in such locations.

[0010] (3) Adding a main engine balancing block is a more effective solution that can generally solve the vibration problem in a targeted manner, but it is relatively expensive and the cost is too high. Summary of the invention

[0011] The technical problem to be solved by the present invention is to overcome the above-mentioned defects in the prior art and provide a new type of vibration-proof structure for the cab.

[0012] The present invention solves the above technical problems through the following technical solutions:

[0013] A novel anti-vibration structure for a cab comprises an outer wall of the cab, wherein the outer wall comprises an upper surrounding wall and a lower surrounding wall, wherein the upper surrounding wall and the lower surrounding wall are connected by anti-vibration channel steels; the anti-vibration channel steels are distributed laterally; the anti-vibration channel steels comprise a groove bottom plate and groove wall plates respectively arranged at both ends of the groove bottom plate, wherein the groove bottom plate and the two groove wall plates form a groove; the groove opening of the anti-vibration channel steels faces the outside of the cab; the bottom of the upper surrounding wall is fixedly connected to the groove wall plate located above the groove opening, and the top of the lower surrounding wall is fixedly connected to the groove wall plate located below the groove opening.

[0014] The groove wall plate located above the groove opening is an upper groove wall plate, and the bottom of the upper surrounding wall is fixedly connected to the end of the upper groove wall plate which is not connected to the groove bottom plate.

[0015] The groove wall plate located below the groove opening is the lower groove wall plate, and the top of the lower surrounding wall is fixedly connected to the end of the lower groove wall plate which is not connected to the groove bottom plate.

[0016] The height of the lower surrounding wall is smaller than the height of the upper surrounding wall.

[0017] An upper vertical support member is fixedly connected to the surface of the upper surrounding wall located in the cab, and the upper vertical support member is fixedly connected to the slot wall plate located above the slot opening.

[0018] The upper vertical support members are distributed up and down along the upper surrounding wall.

[0019] A lower vertical support member is fixedly connected to the surface of the lower surrounding wall located in the cab, and the lower vertical support member is fixedly connected to the slot wall plate located below the slot opening.

[0020] The lower vertical support members are distributed up and down along the lower surrounding wall.

[0021] The outer peripheral wall comprises an oblique surrounding wall distributed obliquely and a vertical surrounding wall distributed vertically, wherein the vertical surrounding wall is located between the oblique surrounding wall and the driving deck; and the anti-vibration channel steel is located inside the vertical surrounding wall.

[0022] No supporting components are provided in the groove of the vibration-resistant channel steel.

[0023] The beneficial effect of the present invention is that the anti-vibration structure of the cab of the present invention blocks the transmission of the vibration of the superstructure to the compass deck by arranging the anti-vibration channel steel. The calculation results of the actual ship show that the anti-vibration effect is very significant. While having the anti-vibration effect, its structural strength also meets the strength requirements. The present invention has a simple structure and low manufacturing cost. It has a very significant anti-vibration effect and can fully meet the strength requirements of the structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Figure 3 for Figure 1 Schematic diagram of the BB cross-section. DETAILED DESCRIPTION

[0027] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, a novel vibration-resistant structure of a cab includes an outer wall of the cab, wherein the outer wall includes an upper surrounding wall 11 and a lower surrounding wall 12 , and the upper surrounding wall 11 and the lower surrounding wall 12 are connected by an anti-vibration channel steel 20 .

[0029] The anti-vibration channel steel 20 is distributed transversely and includes a channel bottom plate 21, a channel wall plate 22 and a channel wall plate 23 respectively arranged at both ends of the channel bottom plate, the channel bottom plate 21 and the channel wall plate 22 and the channel wall plate 23 enclose a groove; the notch of the anti-vibration channel steel 20 faces the outside of the cab.

[0030] In this embodiment, no supporting component is arranged in the groove of the anti-vibration channel steel.

[0031] The bottom of the upper surrounding wall 11 is fixedly connected to the groove wall plate 22 located above the groove opening. The groove wall plate 22 located above the groove opening is an upper groove wall plate, and the bottom of the upper surrounding wall is fixedly connected to the end of the upper groove wall plate that is not connected to the groove bottom plate.

[0032] The top of the lower surrounding wall 12 is fixedly connected to the groove wall plate 23 below the groove opening. The groove wall plate 23 below the groove opening is a lower groove wall plate, and the top of the lower surrounding wall is fixedly connected to the end of the lower groove wall plate that is not connected to the groove bottom plate.

[0033] An upper vertical support member 31 is fixedly connected to the surface of the upper surrounding wall 11 located in the cab, and the upper vertical support member 31 is fixedly connected to the slot wall plate 22 located above the slot. The upper vertical support members 31 are distributed up and down along the upper surrounding wall.

[0034] A lower vertical support member 32 is fixedly connected to the surface of the lower surrounding wall 12 located in the cab, and the lower vertical support member 32 is fixedly connected to the slot wall plate 23 located below the slot. The lower vertical support members 32 are distributed up and down along the lower surrounding wall.

[0035] The height of the lower enclosure is less than that of the upper enclosure. The anti-vibration channel is closer to the bridge deck.

[0036] From the angle between the peripheral wall and the horizontal, the peripheral wall can include an oblique peripheral wall distributed obliquely and a vertical peripheral wall distributed vertically, and the vertical peripheral wall is located between the oblique peripheral wall and the driving deck. The vertical peripheral wall is fixed to the driving deck, and the oblique peripheral wall is fixed to the top of the vertical peripheral wall.

[0037] The purpose of dividing the outer peripheral wall into an inclined peripheral wall and a vertical peripheral wall is to further define the position of the vibration-resistant channel steel.

[0038] The anti-vibration channel steel is located in the vertical surrounding wall. That is, the upper surrounding wall includes the upper part of the vertical surrounding wall and the oblique surrounding wall; the lower surrounding wall only includes the lower part of the vertical surrounding wall.

[0039] It should be noted that in order to avoid confusion in labeling, the attached drawings only mark the upper and lower walls, and no longer mark the inclined and vertical walls.

[0040] The driving cab anti-vibration structure of the present invention is based on the principle of blocking the transmission of the superstructure vibration to the compass deck through the anti-vibration channel steel. The vibration generated by the superstructure below the driving deck is transmitted to the lower surrounding wall, and then significantly weakened when passing through the anti-vibration channel steel. The vibration that passes through the upper surrounding wall and is transmitted to the compass deck is already very small.

[0041] The present invention has been verified by calculation in actual ship design, and the calculation results show that its anti-vibration effect is very significant. While having the anti-vibration effect, its structural strength also meets the strength requirements.

[0042] The cab anti-vibration structure of the present invention has a simple structure and low manufacturing cost, has a very significant anti-vibration effect, and can fully meet the strength requirements of the structure.

[0043] 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.
