Example 1

Referring to fig. 1, the present utility model provides the following technical solutions:

a rail fender comprises a body 1, wherein an inner cavity 11 is formed in the body 1, two ends of the body 1 are fixed ends, and the body is divided into a wide fixed end 21 and a narrow fixed end 22 which are respectively arranged at two ends of a central line of the body 1; the body 1 is provided with a plurality of guide grooves including a wide end guide groove 31 and a narrow end guide groove 32 on the outer side wall of the body 1 and an inner cavity guide groove 33 inside the body 1.

Further, the entire body 1 is drum-shaped and approximately truncated cone-shaped. The body 1 includes a wide end near the wide fixing end 21 and a narrow end near the narrow fixing end 22, between which a smooth transition surface is provided. The wide fixed end 21 is fixedly connected with the ocean platform, and the body 1 is fixed on the side wall of the platform, which needs protection, through the wide fixed end 21. The narrow fixed end 22 is located away from the ocean platform as a direct stressed end that contacts the hull when it is involved in a collision.

Further, the wide fixing end 21 and the narrow fixing end 22 are respectively provided with a threaded hole, the wide fixing end 21 is connected with the platform fixing flange 41 through bolts, and one side of the platform fixing flange 41 is connected with the ocean platform. One way of connecting the platform fixing flange is that it is integrally arranged with the body 1. In another connection mode, a groove corresponding to the platform fixing flange 41 is arranged at the wide end of the body 1, and the platform fixing flange 41 is embedded in the groove at the wide end of the body 1.

The narrow fixed end 22 is provided with a counter bore, a built-in nut 5 is embedded in the counter bore, and the narrow fixed end is connected with a shock-proof plate fixing flange 42 through the built-in nut 5 and a bolt.

Further, the body 1 is made of a rubber material.

The body 1 is fixedly connected with the side wall of a building of an offshore equipment platform through a platform fixing flange 41, a shock-proof plate fixing flange 42 faces one side of a working ship, and the shock-proof plate fixing flange 42 is connected with a shock-proof plate through a built-in nut 5;

through the structure, the body 1 of the device is not in direct contact with the ship body, so that the abrasion degree of the body 1 is relatively lower in use, the service life of a product can be prolonged, and the device is more convenient to install and replace;

example 2

On the basis of the embodiment 1, an inner cavity 11 of the body 1 is provided with an opening at the end face of the wide end, the end face of the narrow end of the body 1 is closed, and the inner wall of the inner cavity 11 of the narrow end is provided with an arc-shaped overload protection pad 12 protruding towards the wide end.

When the body 1 is excessively pressed to cause flattening, the convex end of the overload protection pad 12 is propped against the side wall of the platform, and the overload protection pad can be used as the last layer of protection.

Example 3

On the basis of the above embodiment, the wide end guide groove 31, the narrow end guide groove 32, and the inner cavity guide groove 33 are annular grooves.

The wide end guide groove 31 is arranged on the outer wall of the wide end root part of the body 1, the whole body is annular, the groove bottom is arc-shaped, the notch of the wide end guide groove 31 is arranged towards the direction away from the inner cavity 11, the opening direction is inclined, and the opening direction is inclined towards the narrow end and is opened

The narrow end guide groove 32 is arranged on the outer wall of the middle part of the body 1, which is close to the narrow end, the bottom of the narrow end guide groove 32 is arranged straight, and the notch of the narrow end guide groove 32 is arranged towards the direction away from the inner cavity 11; the narrow end guide groove 32 forms a stepped structure on the outer wall of the body 1.

The inner cavity guide groove 33 is arranged on the inner wall of the middle part of the inner cavity 11 near the wide end, the groove bottom of the narrow end guide groove 32 is also arc-shaped, the notch of the inner cavity guide groove 33 is arranged towards the center direction of the inner cavity 11, and the section of the inner cavity guide groove 33 is positioned between the wide end guide groove 31 and the narrow end guide groove 32.

Through the setting of three guide slots, when this fender device bears hull extrusion, inner chamber guide slot 33 can make body 1 bulge from inside to outside more easily, combines the structure of wide end guide slot 31 simultaneously, and the lateral wall of body 1 is close to the one end of platform, can keep unchanged when being in the atress promptly platform mounting flange 41 and body 1's junction, and the one side of wide end guide slot 31 orientation narrow end takes place deformation. As such, the narrow end guide slot 32 serves the same function. In other words, when the body 1 is deformed by compression, the portion between the narrow end guide groove 32 and the wide end guide groove 31 is more likely to bulge out, enhancing the cushioning effect by the deformation. The stepped straight structure of the narrow end guide groove 32 is more beneficial to reducing the possibility of inclined distortion of the part of the narrow fixed end 22, so that the offset of the central line of the body 1 is reduced as much as possible when the body is pressed.

The scheme is an improvement of the drum-type fender, and the deformation is improved from 52.5% to 72% through a deformation shear test on the fender; the test result shows that the fender has ultrahigh counter force, can withstand 3000 times of fatigue compression and resists 30% of shear deformation; the fender provided by the scheme belongs to an ultra-high counter force and large deformation marine equipment platform protection fender.

The guide groove structure is combined to form a high-counterforce large-deformation design of the fender, and when the fender is subjected to a conventional counterforce, the fender is hardly deformed, so that accurate positioning can be realized; when being subjected to huge impact, the large deformation absorbs impact energy, and the safety of the working ship and the ocean equipment platform is protected.

Finally, it should be noted that: the foregoing description is only a preferred embodiment of the present utility model, and the present utility model is not limited thereto, but it is to be understood that modifications and equivalents of some of the technical features described in the foregoing embodiments may be made by those skilled in the art, although the present utility model has been described in detail with reference to the foregoing embodiments. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
