Method for manufacturing and installing guide rail in container ship cargo hold

Abstract

The invention discloses a method for manufacturing and installing a guide rail in a container ship cargo hold, which comprises the following steps of: (a) manufacturing the guide rail; (b) two-dimensional preassembly: assembling and welding a processed guide plate and the guide rail on a platform by using a doubling plate as a basal plane; (c) hoisting and boarding: installing an eye ring of the guide rail on the guide rail a quarter away from the upper end, respectively installing one eye ring at the left side and the right side of the guide plate, correspondingly reinforcing the eye rings from the back side, and hoisting the whole guide rail to a slipway; adding a toggle plate behind the doubling plate to reinforce the guide rail with low intensity; and after manufacturing the guide rail of a following ship in two segments, connecting the two segments into one guide rail after correction, and hoisting the assembled guide rail; (d) slipway installation: marking, and installing the guide rail; and (e) packaging and testing. In the method, the guide rail is firstly preassembled on the platform by using the doubling plate as the basal plane, and then, the whole guide rail is hoistedonto the slipway and installed. The invention has simple and reasonable method, convenient construction and high guide rail installation accuracy. The upward and downward hoisting and the reasonable arrangement of containers in the cargo hold can be ensured, and thus, the working efficiency and the ship manufacturing quality are increased.

Description

technical field [0001] The invention relates to a method for manufacturing and installing a complete set of components in the shipbuilding industry, in particular to a method for manufacturing and installing guide rails in the cargo hold of a container ship. Background technique [0002] The guide rail for container ships is a device installed on the front and rear transverse cabins to guide the loading and unloading of containers for the convenience of containers entering and exiting the cabin. The guide rails are required to have high precision. At present, many container ships have many platforms in the cargo hold and many longitudinal and transverse bulkheads, and the guide rails are installed on the longitudinal and transverse bulkheads through the docking adjustment plates. The verticality and flatness of the longitudinal and transverse bulkheads, as well as the length, width and squareness of the hatch are affected by deviations, and the installation is difficult, whi...

Problems solved by technology

At present, many container ships have many platforms in the cargo hold and many longitudinal and transverse bulkheads, and the guide rails are installed on the longitudinal and transverse bulkheads through the docking adjustment plates. The verticality and flatness of the longitudinal and transverse bulkheads, as well as the length, width, and squareness of the hatch are affected by the deviation, and the installation is difficult, which greatly affects the shipbuilding progress and shipbuilding quality.
