Sealing plate device of half ship floating end surface

Abstract

The invention discloses a sealing plate device of a half ship floating end surface and belongs to the technical field of ship assembling. The sealing plate device of the half ship floating end surface comprises a sealing plate and multiple first tensioning components, wherein the sealing plate is used for sealing a closure opening of a half ship end surface; multiple first pullers are arranged on the sealing plate; one end of each first tensioning component is connected with a hull; the other end of each first tensioning component is connected with a first puller; and the lengths of the first tensioning components are adjustable. According to the sealing plate device of the half ship floating end surface, the sealing plate and the hull approach each other or are separated from each other through the first tensioning components; and therefore, the sealing plate device to be detached can avoid cutting treatment in the closure opening of the half ship end surface while the sealing condition of a hull cabin is satisfied, the treatment time of the closure opening of the half ship end surface is shortened, and the operation time is shortened; and meanwhile, the labor intensity of operation personnel is reduced.

Description

technical field [0001] The invention relates to the technical field of ship assembly, in particular to a plate sealing device for the floating end face of a semi-ship. Background technique [0002] Due to the length conditions of the dock and the different construction periods of each ship in the dock, half the ship will float during the ship construction process. When the half-ship is floating, according to the floating conditions, part of the cabins on the end of the half-ship needs to be sealed with plates to prevent seawater from flowing into the cabins, and to avoid unnecessary cleaning of the cabins in the later stage. [0003] The existing half-ship floating sealing device is to weld a tooling plate on the closing opening of the outer plate and inner shell plate of the cabin to be sealed at the port of the half-ship, and cut off the corners of the tooling plate after the half-ship is shifted to the pier. Weld seam, remove the tooling sealing plate, and the tooling se...

Problems solved by technology

[0005] On the one hand, due to the narrow space of the internal structure of the hull, it is impossible to use machinery and equipment to directly cut or open the bevel on the closing opening of the hull end surface. It can only be cut manually before beveling

However, the quality of manual cutting is poor, the precision is low, the workload of grinding is large, and the working time is long, which directly affects the accuracy of subsequent loading.

[0006] On the other hand, when the base material or weld of the hull is heated at high temperature for many times, the grains of the weld and the base metal will tend to be coarse, which will greatly reduce the mechanical properties of the base material and weld such as strength and toughness, which has a great impact on the quality control of the hull. bring great risk

DNV GLAS part 2Chapter 4Section 6 stipulates that the weld repair shall not exceed 2 times, while the weld seam welding of the welded half-sealing plate after welding and cutting is equivalent to completing the repair of the entire seam once, and involves dozens of continuous meters of weld rework, the quality risk it brings is inestimable
