Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the improvement of electrical hardware installed on the hull of a ship.

[Prior Art] Conventionally, electrical hardware has been attached onboard ships by manual welding (arc welding).
In that case, the following steps were required.

(A) Positioning (B) Temporary attachment (C) Rebending (D) Final welding As mentioned above, the work process inside the ship is complicated and the work efficiency is low, and it takes a lot of time and can damage the hull paint. was large, and there were problems such as spatter adhesion.

[Problems to be Solved by the Invention] The present invention was made in order to solve the problems of the conventional art, and aims to provide an electrical hardware that can be instantly attached to a ship's hull by stud welding.

[Means for Solving the Problems] When stud welding an electrical hardware such as a metal base to a ship's hull, there is a restriction that the contact between the electrical hardware and the hull must be at one point. For this reason, it is necessary to devise the shape of electrical hardware.

In order to solve the above-mentioned problems, the present invention includes an electric circuit main body for supporting electric wires made of round bars or flat bars, or a stand main body for supporting small equipment;
An electrical hardware for mounting on a ship, characterized in that its tip has a protrusion for stud welding, and its rear end consists of only one stud pin fixed by welding to the vicinity of the center of the electrical circuit main body or the stand main body. provide.

[Function] According to the electrical hardware of the present invention, by connecting an arc stud welding machine to the completed electric circuit main body or stand main body and supplying welding current, the protrusion for stud welding at the tip of the stud pin and the ship's hull can be connected. The tip of the stud pin and the hull can be stud-welded by generating an arc between them. Therefore, the electrical hardware of the present invention can be instantly attached to the ship's hull by stud welding, which can significantly shorten the working time onboard the ship, where work efficiency is low, and the welding quality is also improved. It is possible to obtain a good one.

[Example] Hereinafter, an example of the present invention will be described in detail.

Embodiment 1 FIG. 1 shows an electrical circuit 9 which is an electrical hardware. This electric circuit 9 includes a circuit main body 1 made of a small diameter round rod, a stand pin 2 having a protrusion 2a for stud welding at its tip, and a stand pin 2 whose rear end is fixed near the center of the circuit main body 1 by welding. Consisting of

Next, the work of attaching the above-mentioned electric line 9 to the hull will be explained.

By connecting an arc stud welding machine to the main body 1 of the electrical circuit 9 shown in FIG. 2A through the attachment 3 as shown in FIG. 2B and supplying welding current, the stand of the electrical circuit 9 is The tip of the pin is instantly attached to the hull (not shown) by stud welding. By performing such an installation operation a plurality of times, a plurality of electrical circuits 5, 5' having electrical circuit bodies that support the electrical wires 4 can be mounted on the hull as shown in FIG. 2C.

Embodiment 2 FIG. 3 shows a small equipment stand 8 which is electrical hardware.
Figure A shows an I-type small equipment stand 8, Figure B shows a T-type small equipment stand 8, and Figure C shows an H-type small equipment stand 8. These small equipment stands 8 have a stand main body 6 made of a flat bar, a stud welding protrusion 2a at its tip, and one stand pin 2 whose rear end is fixed near the center of the electrical circuit main body 1 by welding. Consisting of

Next, the work of attaching the above-mentioned small equipment stand 8 to the hull will be explained using an I-type small equipment stand 8 as an example.

Stand main body 6 of I-type small equipment stand 8 shown in FIG. 4A
As shown in FIG. 4B, by connecting an arc stud welding machine via the attachment 3 and supplying welding current, the tip of the stud pin of the small equipment stand 8 is instantaneously welded to the hull (not shown) by stud welding. Attach to. Thereafter, as shown in FIG. 3C, the small equipment 7 can be supported on the main body 6 of the small equipment stand attached to the hull.

[Effects of the invention] As detailed above, according to the present invention, it is possible to instantly attach it to the ship's hull by stud welding, so it is possible to significantly shorten the installation time on board the ship and to make the welding quality uniform. Furthermore, it is possible to provide electrical hardware having remarkable effects such as extremely little paint damage and spatter adhesion on the mounting surface.
