Compound berth-alongside device for elevated trestle

Abstract

The invention discloses a compound berth-alongside device for an elevated trestle and relates to the technical field of ships. The compound berth-alongside device comprises N columns, a cross beam andbuffer mats, a buffer layer is wrapped on the outer side of each column, the columns are arranged in parallel, the cross beam perpendicularly stretches across one sides of the columns and forms bentstructures with the columns respectively, the buffer mats are arranged between every two columns and connected with the cross beam, and the buffer mats are in contact with the cross beam and a trestlebox body respectively. According to the compound berth-alongside device for the elevated trestle, a single cross beam is adopted to connect a single row of columns into an entirety, small distributedbuffer mats are arranged between the cross beam and the trestle box body so that a tertiary compound berth-alongside energy absorption structure can be formed, the collision force during ship berthing is effectively dispersed, and the requirement of safety berthing alongside in limited berthing space for the elevated trestle is sufficiently met.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a compound berthing device suitable for elevated trestles. Background technique [0002] With the continuous development and construction of marine islands and reefs in my country, it is necessary to build a certain length of elevated trestles around the islands and reefs for the transportation of personnel and goods from barges to islands and reefs. The bridge section box of the elevated trestle is supported above the water surface by pile legs, one end is connected to the shore through a springboard, and the other end of the trestle box side needs to be equipped with suitable berthing devices for safe berthing and docking of various types of ships. transport. In order to ensure that the boat can safely berth on the trestle bridge, its berthing device should be able to provide appropriate elastic stiffness so as to effectively absorb the collision energy. [0003] At present, th...

Problems solved by technology

However, there are the following outstanding defects when the current dock berthing device is directly applied to the elevated trestle: (1), it is difficult to provide sufficient buffer performance in the limited space on the side of the elevated trestle, because the height of the elevated trestle box is very small, If the wharf berthing device is directly used, the rubber ball cannot be used due to its large scale, and the cushioning effect provided by the rubber tire or rubber fender is very limited due to the limited scale, that is, a single rubber material is used for berthing in a limited space It is difficult for the device to guarantee the safety of berthing ships; (2), point contact and concentrated force are likely to cause damage to the trestle bridge, because when various types of boats berth, usually a certain local area collides with the trestle box first, and the local rubber material itself Due to the limitation of scale, it is impossible to disperse the concentrated contact force at this point to a wider range, so it is easy to cause damage to the structure of the trestle box; (3), the type of berthing boats is greatly restricted, due to the small height of the trestle box, A single conventional rubber material is only limited to this height, which makes it impossible for boats with a small freeboard to berth. When a boat with a large freeboard is berthed, it will affect the safety of berthing because it goes too deep into the trestle deck area.
