Supporting tool for spraying zinc to surface of fence small assembly of ship deck

Abstract

The invention relates to the technical field of ship manufacturing, and discloses a supporting tool for spraying zinc to the surface of a fence small assembly of a ship deck. The supporting tool for spraying zinc to the surface of the fence small assembly of the ship deck comprises a supporting rack and a lateral limiting device, wherein the lateral limiting device is arranged on the upper portionof the supporting rack and is used for preventing the fence small assembly from tilting leftwards or rightwards; the supporting rack comprises a seat block; the left side and the right side of the seat block are separately connected with a left supporting rod and a right supporting rod through hinges; the upper end of the seat block is connected with the lateral limiting device; and the lateral limiting device comprises a connecting arm, a left bent catch pawl and a right bent catch pawl, the connecting arm is arranged horizontally, the left bent catch pawl and the right bent catch pawl are arranged at the two ends of the connecting arm, extend upwards and are used for limiting the left side surface and the right side surface of a handrail in the fence small assembly; and a gap for zinc spraying to the handrail is formed between the connecting arm and the handrail. The zinc spraying quality and efficiency are improved, and meanwhile, the cost for supporting auxiliary materials is saved.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a supporting tool for spraying zinc on the vertical surface of a panel fence on a ship's deck. Background technique [0002] In the process of making large-scale ship deck sections, a large number of sheet-shaped fence groups need to be produced. The height of these sheet-shaped fence groups is about 2.6 meters, and the width ranges from 1 to 8 meters. Galvanizing work needs to be completed before installation. [0003] In the prior art, in order to galvanize the fence group stand, it is necessary to hoist the fence group stand and fix it vertically. The anti-dumping measure is to use angle steel and channel steel for support, and mainly use electric welding to fix it. This method mainly has the following shortcomings : [0004] One is that a large number of supporting auxiliary materials are installed in sections of the whole ship, and the auxiliary cost is relatively larg...

AI Technical Summary

Problems solved by technology

[0004] First, a large number of supporting auxiliary materials are installed in sections on the whole ship, and the auxiliary cost is relatively large;

[0005] The second is that the sheet fence group stand and support are fixed by electric welding, which destroys the integrity of the galvanized surface layer;

[0006] The third is that a large amount of grinding work is generated after the support is removed, and the labor cost increases;

[0007] Fourth, the damaged galvanized part after the support is removed needs to be resprayed with zinc, which prolongs the production cycle and reduces the efficiency of the operation
