Description

Container ship with special crane for container

Technical Field

The invention relates to a container transport ship, in particular to a container transport ship provided with a special crane for a container.

Background

With the increasing deepening of globalization, the development of all regions and countries around the world is unbalanced, the trade is rapidly increased, the quantity of goods transportation is greatly increased, and the container sea transportation is also vigorously developed as a large-scale transportation mode which is more economic and safer. The in-process of loading and unloading the container of current container ship all hoists through equipping the container crane on the pier, does not hardly load and unload the container at the pier that does not have special crane of container, but the high efficiency of container transportation makes the people difficult to refuse again with convenient, however, all container ships do not set up the container crane at present, do its reason, mainly have following three big problems to be difficult to solve: firstly, due to the height limit requirement of the navigation standard on the ship, the contradiction between the loading height of the container ship and the height space occupied by the crane is difficult to reconcile, namely if the container crane is moved to the container ship according to the conventional technology, the highest point of the crane cannot be higher than the highest size standard of the corresponding ship grade, otherwise, the crane collides with a bridge, the distance between the container crane and the top of the highest layer of container which can be lifted by the container crane is larger, and generally equals to the height of two layers of containers, so if the container crane is simply moved to the container ship, the cargo carrying capacity of the ship is reduced by two layers of containers, and the reduction range of the carrying capacity cannot be accepted; secondly, if a container crane is equipped on a container ship, if a container is to be lifted from a cabin to a wharf or from the wharf to the cabin, the container crane must have a boom extending to both sides of the ship (i.e. the wharf), and the extending length of the boom must be greater than the width of the container plus the safe operating distance between the ship and the wharf, generally not less than 5 meters, however, the lateral extension of a structure on the ship, such as 5 meters or more, is a great hidden danger for the navigation safety, and is not allowed; thirdly, the aligning speed of the container crane to align the container lifting hole is an important factor influencing the lifting efficiency, so a new means is needed to improve the lifting efficiency; fourthly, due to the action of tide, the height of the ship board relative to the wharf ground (working face) changes along with the change of the tide level, so that corresponding requirements are also put forward on the working height of a container crane on the container ship, and if the lifting height of the crane is not enough in the low tide level, the operation of loading and unloading the container cannot be realized; fifth, since the servo motor is used to control the crane system, the crane can be quickly lifted at high acceleration, but the high acceleration will generate a moment of supergravity, so that it is necessary to keep the crane stable and safe by balancing the weight on the opposite side of the working surface of the cantilever.
