Conventionally, when performing a hot-dip galvanizing treatment or the like, an alkaline aqueous solution used in a degreasing step, a hydrochloric acid or sulfuric acid aqueous solution used in a pickling step, and washing, galvanizing treatment and cooling treatment performed after each step. Fumes (including white smoke and water vapor) are generated. Since these fumes lead to air pollution, the entire space used for the hot-dip galvanizing process is covered with a closed room (sealed room) so that it does not leak to the outside, and the movement of heavy objects during the process is prevented inside the closed room. This is done using a hoist mounted on the ceiling of the building. However, the rate of corrosion and deterioration of the hoist was high due to the fumes remaining in the closed chamber, and it was necessary to replace the hoist in a short period of time.

As one means for solving this problem, a gap is provided in the ceiling of the closed room, a hoist is installed on the ceiling of the building covering the closed room, and wires and hooks hanging from the hoist are provided on the ceiling of the closed room. From the inside to a closed chamber, and using it to move between processing steps. However, in the conventional hoist structure, in order to improve the operability of the wires and the hooks, the wire ends of the two wires hanging down from the hoist are arranged widely across the drum for winding the wires. In this state, as shown in FIG. 1, regardless of the traveling direction of the hoist, the operating range of the wire is wide, and the width of the gap provided in the ceiling of the closed chamber is also wide. Then,
It becomes difficult to fill the gap with a seal or the like. Therefore, there is a problem in that the amount of fume passing through the gap is large, and the fume comes into contact with the hoist disposed above the gap, and the hoist is easily corroded.

[0007] A gap is provided in the ceiling of the closed room provided in the building, and an elastic fume leakage prevention sheet such as a rubber or vinyl chloride sheet is attached to the gap. This fume leakage prevention sheet is normally in a state where it covers the top of the sealed room so as not to leak the fume, but only the part touching the ship-like lid attached to the wire is elastically deformed Has the property of not hindering the movement of the ship-like lid. The hull lid attached to the wire of the hoist is elastically deformed while pushing the fume leakage prevention sheet covering the top space of the closed chamber in accordance with the movement of the hoist. Therefore, the shape of the hull lid is desirably streamlined.

By the above means, the hoist device of the present invention is arranged such that the loop formed by the wire is arranged in parallel with the rotation axis direction of the wire winding drum, and is arranged in parallel with the traveling direction of the hoist. Even if the winding drum rotates and the hook moves up and down, the wire does not swing right and left with respect to the rotation axis direction of the drum.

[0010] Furthermore, an elastic fume leakage prevention sheet is attached so as to close the gap provided in the ceiling of the closed chamber, and when the hoist moves along the gap of the ceiling of the closed chamber, it passes through both wires hanging down from the hoist. The lid
Since the fume leakage prevention sheet is pushed and advanced, the amount of fume leaking from the gap provided in the ceiling of the sealed room can be extremely small.

Hereinafter, embodiments of the present invention will be described in detail.
FIG. 1 is a front view of a conventional hoist, and FIG. 2 is a side view thereof. The wire 1 hanging down from the hoist has a structure in which a wire winding drum 3 winds one of the wire ends 2 and the other wire end 2 is attached to a part of the hoist across the drum 3. In this method, the wire attachment width is large. In addition, the movement of the wire in the drum direction is large due to the winding of the wire winding drum. Therefore, it is necessary to increase the width of the gap provided in the ceiling of the closed chamber, and as a result, the amount of fume flowing out increases.

FIG. 3 is a front view of a hoist used in the present invention, and FIG. 4 is a side view thereof. The wire 1 hanging down from the hoist is wound by one of the wire ends 2 by the wire winding drum 3, and the other wire end 2 is not straddled by the wire winding drum 3, but on the side of the hoist in the same direction as the wire winding side. It is structured to be attached to the part 4. That is, the loop formed by the wire and the rotation axis direction of the winding drum of the wire are arranged in parallel. Further, the loop formed by the wire and the winding drum for the wire are arranged parallel to the traveling direction of the hoist device. For this reason, the width of one of the wires is almost nil, and even when the hook 6 attached to the tip of the wire is moved up and down, the wire 3 does not swing right and left with respect to the rotation axis direction of the drum.

FIG. 7 is a top view showing a state where the fume leakage prevention sheet D contacts the boat-shaped lid 5 as the hoist moves, FIG. 8 is a side view thereof, and FIG. 9 is a front view thereof.
As shown in the figure, in the fume leakage prevention sheet D, only the portion of the fume leakage prevention sheet D that the boat-shaped lid 5 contacts is turned up or raised. Since the boat-like lid 5 attached to the wire 3 suspended from the hoist device pushes and moves the fume leakage prevention sheet D in this manner, the movement of the hoist is smooth and the wire 3 is entangled with the fume leakage prevention sheet D. To prevent Furthermore, it has the function of preventing fumes from leaking from the gap in the ceiling of the closed room.
