Description

Rubber fender for wharf

Technical Field

The utility model belongs to the technical field of the boats and ships shock attenuation, a pier rubber fender is related to.

Background

With the proposal of carbon neutralization and interest policy of the state 2030, the high tide heat degree of the domestic LNG receiving station investment construction is not reduced, and how to improve the compatibility of the wharf in the domestic limited wharf shoreline resources, thereby increasing the utilization rate of the berth and releasing the wharf receiving and unloading capacity becomes a topic concerned by investors and operators together. And the compatibility of the wharf is improved, namely the wharf is compatible and matched with more LNG ships with different types and tonnages, and firstly, the safety mooring of the wharf by the LNG ships is ensured.

The fender is widely applied to wharfs, and when the wharfs and the ship body collide with objects, the wharfs and the ship body are better protected. The existing fender has a plurality of types, wherein drum-shaped rubber fenders are used more frequently, and the existing drum-shaped rubber fenders are generally connected with a fender shell and a buffer plate.

Patent CN204753507U discloses a drum-shaped rubber fender built-in telescopic guide sleeve, which is characterized in that a drum-shaped rubber fender built-in guide sleeve composed of an inner sleeve, an outer sleeve and a limit block installed in the inner hole of the outer sleeve is arranged in the inner hole of the existing drum-shaped rubber fender, one end of a cylinder of the outer sleeve is welded with a flange plate, the inner sleeve and the outer sleeve are respectively inserted from two ends of the inner hole of the drum-shaped rubber fender and are mutually sleeved and buckled through a sector block, the drum-shaped rubber fender is clamped after rotating for a certain angle, the flange plate at one end of the drum-shaped rubber fender is overlapped with the flange plate of the outer sleeve and is connected with a wharf through a bolt, the gravity of a fender and the gravity of the drum-shaped rubber fender is directly borne by the outer sleeve, the drum-shaped rubber fender is free from shearing force, the flange plates connected at two ends are not easy to crack, the flange plate which is cracked and even seriously damaged can still be normally used, and the service life of the drum-shaped rubber fender is prolonged.

In order to deal with the condition that the force of the fender is uneven, the drum-shaped rubber fender has a certain gap between the inner sleeve and the outer sleeve, so that the fender can incline towards any direction. However, in the above structure, if a gap exists between the inner sleeve and the outer sleeve, the inner sleeve is tilted at the rear end and tilted at the front end under the action of gravity in the daily use process, so that the inner sleeve does not have the function of gravity support for the fender, and the fender still causes the outer end of the drum-shaped rubber fender to be subjected to larger shear stress under the action of the fender, a flange and the like, and is easy to crack; if a guide strip is designed between the inner sleeve and the outer sleeve to ensure that the inner sleeve is in a horizontal state at ordinary times, even if a gap is formed between the inner sleeve and the outer sleeve when the anti-impact plate is subjected to uneven external force, the inner sleeve can only axially slide under the action of the guide strip, and the inner sleeve and the outer sleeve are still easily damaged.

Disclosure of Invention

The utility model discloses an above-mentioned problem to current technique exists provides a pier rubber fender, the utility model aims to solve the technical problem that: how to improve the service life of the rubber fender.

The purpose of the utility model can be realized by the following technical proposal:

a rubber fender for a wharf is characterized by comprising a base, an impact prevention plate and fender shells, wherein the base can be fixed on a wharf, the number of the fender shells is two, the fender shells are distributed at intervals in the horizontal direction, the inner ends of the fender shells are fixed on the base, and the outer ends of the fender shells are connected with the impact prevention plate; the rubber fender further comprises an outer sleeve, an inner sleeve and a hollow rod which are positioned in the fender shell, the inner end of the outer sleeve is fixed on the base, and the outer surface of the outer sleeve is in contact with the inner surface of the fender shell; the inner sleeve is arranged in the outer sleeve in a sliding mode, the outer end of the inner sleeve is connected with the inner end of the hollow rod in a universal mode, and the outer end of the hollow rod is connected with the anti-impact plate; the aperture of the hollow rod is the same as that of the inner sleeve, the base is provided with a linear driving source, and the output end of the linear driving source is connected with a supporting shaft which can be simultaneously inserted into the inner sleeve and the hollow rod and is jointed with the inner sleeve and the hole wall of the hollow rod.
