Description

Foldable explosion-proof lighting device using a station joint {Lighting device for preventing explosion using station joint}

The present invention relates to a folding-type explosion-proof light device using a station joint, and more particularly, an explosion-proof light installed as a lighting device on the ceiling or stairs of a factory building in an industrial site with an explosion risk. It relates to a foldable explosion-proof lamp device using a station joint that allows easy replacement and maintenance without use.

In general, in industrial sites where there is a risk of explosion, when an explosion occurs in the container of the lighting fixture, as well as the necessary work for a certain purpose, when the lighting fixture is replaced or maintenance work, it withstands the pressure and the flame leaks out. Explosion-proof lamps for explosion-proof explosion-proof are used.

Explosion-proof lamps used in this way must be used in accordance with relevant laws and regulations, especially in places where there is a risk of explosion, such as chemical plants, explosives plants, oil refineries, and gas storage facilities that handle flammable substances. This is because there is a risk of explosion of flammable substances due to the like.

Therefore, the explosion-proof lamp has a structure that can easily withstand the explosion pressure and block the leakage of flame or gas to the outside, even if a flammable external gas enters into the container and causes an explosion due to flame or heat generation of the internal electric circuit. It must be made.

That is, the explosion-proof lamp must have mechanical strength to withstand the internal explosion pressure, and the flame or hot gas generated by the internal explosion must not be ignited by external gas through the container joint such as explosion-proof, and the outer surface of the container Requirements such as that the temperature does not reach the ignition temperature of the external gas must be satisfied.

In general, explosion-proof lamps that meet the above requirements are installed at high positions such as the ceiling or stairs of industrial sites and factory buildings with the risk of explosion, that is, at high altitudes out of reach of workers in order to make the work site wider and brighter. It is fixedly installed using brackets on pipes.

That is, the explosion-proof lamp is mounted on an installation surface at a high altitude by a mounting box supporting the explosion-proof lamp, and a ballast housing with a ballast built in to supply power to the explosion-proof lamp is also mounted on a high altitude position.

However, the explosion-proof lights and ballast housings with built-in ballasts that are installed at high altitudes as above have to be replaced or maintained through regular or regular inspections to maintain the function according to the requirements. Since it is installed at a high altitude, out of reach of workers, such as a high ceiling or stairs, there is not only the inconvenience of using a separate sky equipment such as a high place work vehicle when inspecting or replacing explosion-proof lights, but also explosion-proof lights. There is a problem that the workability of inspection or replacement is greatly degraded.

Moreover, there is a problem in that the safety of the worker is not secured, such as the risk of a safety accident due to carelessness, when the worker boards the sky equipment such as the above-mentioned high place work vehicle, and there is a significant cost in maintenance of the lighting equipment. There is a problem that is economically inefficient, such as required.
