Let-down system for ship

Abstract

The invention relates to a let-down system for ship, comprising a plurality of moving units (10), which can support and move the ship body (5) of the ship, and a guide rail (20), which guides the plurality of moving units 10 along a straight line, wherein the guide rail (20) is a grid structure that can move the ship body in length direction and width direction selectively. The guide rail is a grid structure that can move the ship body in length direction and width direction selectively, so the working field can be used fully as a pre-loading and loading field, thus reducing the investment greatly. The usage of trolleys minimizes the frequency of using large crane and improves the working efficiency greatly. A plurality of block bodies can be put into action without limitation of large or medium groups, thus making a full use of the narrow field. The flexibility of submerging and loading computation or operation can be put into full use to shorten the construction period and maximize the turnover efficiency.

Description

technical field [0001] The present invention relates to a ship launching system, in particular to a ship launching system in which guide rails are set in a grid structure so that the hull can be selectively moved in the length direction and width direction, thereby making full use of the existing workplace and simultaneously serving as a It can be loaded first and used in the loaded place, thereby greatly saving investment costs. Moreover, the use of trolleys is fully utilized to minimize the use of large cranes and greatly improve work efficiency. Moreover, a plurality of blocks can be operated simultaneously without being limited to a large or medium group, thereby being able to make full use of a narrow site. Moreover, the flexibility of calculation or work for flooding and loading and unloading can be exerted, so that the construction time can be advanced to maximize the turnover rate. Background technique [0002] Usually, ships transporting goods overseas are manufac...

AI Technical Summary

Problems solved by technology

[0006] However, the launching system of this prior art ship can only be carried along the lengthwise direction along the in-line guide rails, so since the site space is basically only used for carrying, it not only reduces the space efficiency, but also requires the use of trolleys and large Cranes thereby reducing work efficiency, and, since it is limited to block work of the ship, it cannot make full use of the site and the flexibility for flooding and loading and unloading calculations or work is limited
