Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] This invention relates to the arrangement of elevator machine rooms.

[Prior art]

First, the layout of a conventional elevator machine room will be explained with reference to FIGS. 1 and 2. In the figure, (1) shows the hoisting machine, (2) shows the control panel, and (3) shows the speed governor. These are usually installed on the same floor.

The area where the equipment is placed is generally the hoisting machine (1) and the speed governor (3).
is placed at the top of the descent path, that is, on an area of X x Yl.

Therefore, the control panel (2) is placed in a space next to the hoisting machine (1). That is, it is arranged in an area of (X XY2 ) -X xYs. This space is determined so as not to interfere with normal maintenance, etc., and is approximately X X Y2 / X X Yi
It is said that if the value is 1.5 to 2 times, it is possible to not only store one piece of equipment but also secure the work space necessary for maintenance.

The control panel (2) has 131 stations mutually with the hoisting machine (1).
For maintenance, etc., they are usually placed on the same floor. Therefore, there was a drawback that the machine room could not be placed within the hoistway area (XxYs) in order to place the control m(2).

Furthermore, since the control panel (2) is placed horizontally due to the area of the hoistway, it is especially difficult to install the machine room in the middle of the building.
There were problems such as protruding into the corridors and rooms of the building, reducing the area of comfortable living rooms near windows, and disrupting the traffic flow within the building.

[Summary of the invention]

This invention solves the above-mentioned problems.

The machine room, which has the same cross-sectional area as the hoistway, is divided into two layers, upper and lower, and is stored in one roll, thereby preventing the machine room from expanding horizontally. The purpose is to prevent a decrease in the area of comfortable living rooms.

[Embodiments of the invention]

An embodiment of this invention will be described with reference to FIGS. 3 to 5. (S) is a hoistway, which has a depth dimension Y3 and a width dimension X. (C) is an elevator car. (Rd) is a lower machine room immediately above this hoistway (S), which has a floor area equal to the cross-sectional area of the hoistway (8). (Ru) indicates an upper machine room located directly above this lower machine room (Rd) and having the same floor area. 0υ are two hoisting machines installed in the upper machine room (Ru), which are placed side by side with a space the size of one elevator in between. α2 is installed between two hoisting machines (1]). The control &1 device that controls each hoisting machine 0υ, α9, is a speed governor that is provided corresponding to each car (C'l) and detects the speed, and is installed in the lower machine room (Rd). is installed in the machine room (Rd) for the upper and lower layers of the 1st roll, and is installed at a location directly below the space sandwiched between the 9th hoist αυ.

In the machine room with the above configuration, the area of the machine room is 9.

This is the total value of the upper machine room (Ru) and the lower machine room (Rd).

In other words, the hoistway cross section flXY3 is 2XY3.
This doubles the size of the space, making it possible to store the necessary equipment and also secure the work space necessary to maintain the stored equipment.

Note that the upper machine room and the lower machine room do not necessarily have to have the same cross-sectional area as the hoistway.

〔Effect of the invention〕

This invention has been described above, and a lower machine room is provided immediately above a hoistway in which a plurality of elevators go up and down, and an upper machine room is provided 1 nn above this lower machine room, and windings are installed in each machine room. Since the upper machine and the control panel are arranged in a dispersed manner, it is possible to prevent the nine machine rooms from expanding in the horizontal direction, and this has the effect of preventing a decrease in living area in areas with good livability.
