Embodiment Construction

[0033] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only the parts related to the present invention are shown in the drawings but not all of them.

[0034] This embodiment provides a groove waterproof device, which is used in the anti-rainwater corrosion of the groove 6 of the workpiece 5 to be welded. Corrosion of liquids such as rainwater avoids secondary rework and grinding of workpieces to be welded, speeds up construction progress, and improves construction efficiency.

[0035] Such as figure 1 As shown, the groove waterproof device provided in this embodiment includes a sealing plate 1 and a locking assembly 2 . The ...

Abstract

The invention relates to the technical field of ship building and assembly operation, and particularly discloses a groove waterproof device and a using method of the same. The groove waterproof devicecomprises a sealing plate and a locking assembly, wherein the sealing plate is used for covering a groove of a workpiece to be welded; and the locking assembly is used for pressing the sealing plateto abut against the workpiece to be welded, and the locking assembly is arranged through penetrating through the sealing plate and can move up and down relative to the sealing plate. According to thegroove waterproof device, when the groove of the workpiece to be welded is polished to be bright and reaches a welding requirement, the sealing plate is put to cover the groove of the workpiece to bewelded, the locking assembly is made to penetrate through the groove and is used for locking the sealing plate, so that the sealing plate is tightly pressed against the workpiece to be welded, the groove is covered by the sealing plate, so that liquids such as rainwater cannot enter the groove from the sealing plate, the rainwater and other liquids can be prevented from seeping into the groove, therefore the groove is effectively prevented from being rusted, secondary reworking and polishing of the groove are avoided, the construction progress is accelerated, and the construction efficiency isimproved.

Description

technical field [0001] The invention relates to the technical field of shipbuilding and assembly operations, in particular to a groove waterproof device and a method for using the device. Background technique [0002] There are a large number of flat butt weld welding operations in the open air in shipbuilding. The welding process requires that the flat butt weld seam need to be grooved and polished before welding, and the welding can only be started after the pre-weld inspection is passed. During the period from grinding to welding, it is possible that due to rainy weather, rainwater will intrude into the polished weld to be welded, causing corrosion of the polished weld again, resulting in secondary rework and grinding, affecting the construction progress and reducing construction efficiency. Contents of the invention [0003] An object of the present invention is to provide a groove waterproof device to prevent the groove from being corroded by liquids such as rainwate...
