Multifunctional cargo-blocking railing for maritime work auxiliary ship

Abstract

The invention relates to a ship cargo-blocking pulling rod comprising a front-middle cargo-blocking railing part and a tail cargo-blocking railing part. The front-middle cargo-blocking railing part isequal in height, and the height is 2.7-2.8 m. The tail cargo-blocking railing part is in the shape with the height being gradually decreased from front to back. A section of overlapped part is formedbetween the front-middle cargo-blocking railing part and the tail cargo-blocking railing part and forms a limiting blocking fork. A staff passage is formed by the space between the front-middle cargo-blocking railing part and an outer side high bulwark. According to the ship cargo-blocking pulling rod, a cargo-blocking railing adopts a height-variable form, so that the using demands of differentoperation are met; a deck area at the front-middle part adopts a high cargo-blocking railing form, so that fixing of deck cargoes is facilitated, and the convenient, fast and safe staff passage is formed by the deck area and the outer side high bulwark; a tail broadside area adopts a low cargo-blocking railing form, so that oil extraction operation is facilitated; and the height of the cargo-blocking railing is not increased through the horizontal limiting blocking fork, so that helicopter hovering operation on a tail deck is not affected.

Description

technical field [0001] The invention relates to a cargo-stopping pull rod for a ship, in particular to a multi-functional cargo-stopping railing for a marine engineering auxiliary ship, which belongs to the technical field of the cargo-stopping railing for ships. Background technique [0002] The common operation types of offshore engineering auxiliary ships mainly include the following types: 1. Loading deck cargo; 2. Cooperating with shuttle tankers for oil lifting operations; 3. Towing; 4 Cooperating with helicopters to hover. Different types of operations of offshore engineering auxiliary ships have different requirements for the form of cargo railings: the loading of deck cargo requires the cargo railing to be as high as possible, which is conducive to fixing the deck cargo and is more conducive to protecting the personnel passage outside the cargo railing ;During oil lifting operations, the cargo railing at the tail should be as short as possible, which is beneficial t...

AI Technical Summary

Problems solved by technology

[0014] The technical problem to be solved by the present invention is: the existing ship cargo bar is divided into three types: the middle fork type high cargo railing, the tail fork type high cargo railing, and the middle fork type low cargo railing. Cargo railings cannot simultaneously fulfill the functions of loading deck cargo, carrying out oil lifting operations with shuttle cruise ships, towing, and hovering with helicopters, resulting in insufficient overall usability and convenience for common operations of offshore auxiliary ships
