Description

[Detailed Description of the Invention] This invention relates to an elevator machine room device.

first. A conventional elevator machine room device will be explained with reference to FIGS. 1 and 2.

In the figure, 1 is the floor of the machine room, 1a is a through hole provided in this, 2 is a weir plate provided on the inner surface of the through hole 1a and protrudes upward, and 3 is poured on the floor 1. Cinder concrete, 4 is a cylindrical soundproof duct fitted into the space formed by the weir plate 2, 4a is a flange fixed to the outer surface of this duct,
4b is a sound absorbing material coated on the inner surface of the soundproof duct 4;
5 is a machine stand installed on the floor 1, 6 is a hoisting machine placed on top of this via a vibration-proof rubber 7, and 8 is a deflection wheel pivotally attached to the lower side of the hoisting machine 6. 9 is a main rope that is wrapped around this and the sheave of the hoist 6 and inserted into the soundproof duct 4.

That is, the weir plate 2 is provided in the through hole 1a, and the cinder concrete 3 is cast, and the weir plate 2 prevents the cinder concrete 3 from flowing out into the through hole 1a. A soundproof duct 4 is provided to prevent noise from the machine room from being transmitted to the outside through the insertion portion of the main rope 9. but,
Since the weir plate 2 and the soundproof duct 4 are required, the production and installation thereof requires complicated labor and costs.

This invention is intended to eliminate the above-mentioned drawbacks, and is intended to provide an elevator machine room device that has a simple structure and can provide the required soundproofing effect.

An embodiment of this invention will be explained below with reference to FIG.

In the figure, the same reference numerals as in FIGS. 1 and 2 indicate corresponding parts, and 10 is an enclosure that is fitted into the through hole 1a and extends above the floor 1.

That is, the enclosure 10 is attached to the floor 1 and the cinder concrete 3 is cast, and the outer periphery of the enclosure 10 is filled with the cinder concrete 3, and the outflow to the through hole 1a is prevented. Therefore, the weir plate is not required, and the function and soundproofing effect of the weir plate can be obtained with a small number of members, making it possible to manufacture and install it at low cost.

Figure 4 shows another embodiment of this invention.
In the figure, the same reference numerals as in FIG. 3 indicate corresponding parts, and 10 is a box-shaped enclosure housing a part of the diverter wheel 8, and a main cable hole 10a is provided in the bottom surface.

That is, in this embodiment as well, the enclosure 10 is provided to protrude above the floor 1, so a detailed explanation will be omitted, but it is clear that the same effect as in the embodiment of FIG. 3 can be obtained. .

As explained above, this idea is to penetrate the lower part of the enclosure whose inner surface is coated with sound absorbing material into a through-hole in the floor, and place the upper part to protrude from the upper surface of the cinder concrete. Since the present invention is also used as a shedding plate, the function of the shedding plate and soundproofing effect can be obtained with a small number of members, thereby realizing an elevator machine room device that can reduce manufacturing and installation costs of the elevator.
