Description

[Detailed Description of the Invention] This invention relates to the structure of installing a counterweight in an elevator shirt If a plurality of elevators are arranged adjacent to each other in pairs.

When designing a skyscraper, an important issue is how to reduce the elevator space that occupies the standard floor area.

In the past, depending on the placement of elevators, the column divisions and basic dimensions (modules) of the building could change.

Therefore, research is being conducted on how to reduce the elevator shaft space as well as the elevator layout.

As shown in FIG. 1, a conventional elevator is provided with a corresponding counterway (b) for each elevator car (a) and within each elevator shaft (c).

However, the size of the planar cross section of the counterweight can be appropriately set regardless of its weight.

Therefore, this idea was developed to narrow the space between the cages of both elevators in an elevator shaft where multiple elevators are arranged next to each other in pairs, and to use this space in common by arranging the counterweights of both elevators side by side. An attempt is made to provide an elevator counterweight installation structure that is designed to improve efficiency, reduce the space of the elevator shaft, and ultimately save the structural material of the guide rail of the counterweight. It is something.

This invention will be specifically explained below based on the embodiments shown in FIGS. 2 and 3.

In the figure, reference numeral 1.1 designates an elevator car, which is arranged within the elevator shaft 2.

In the embodiment of FIG. 2, the gauges 1, 1 are arranged back to back, and a beam 3 arranged between the two cages 1.1 is connected to a guide rail 5, via a bracket 4, 4.4 on one side thereof. 5.5 are attached, and the counterweights 6.5 of the two cages 1, 1 are attached to these guide rails.
6 is installed horizontally between two cages 1, 1 in a vertical plane perpendicular to the direction in which the cages 1, 1 are lined up (vertical direction in Fig. 2) and can be freely moved up and down. .

Note that the central bracket 4 and guide rail 5 are shared by each counterweight 6.6 in each elevator car 1.1.

Each of the counterweights 6.6 has slide grooves 7.7 formed on both sides, and these are slidably fitted into the guide rails 5, 5.

In such a configuration, the counterweights 6.6 of the cages 1.1 are arranged horizontally between the cages 1, 1 in one vertical plane orthogonal to the direction in which the cages 1.1 are arranged, and are freely movable up and down. Therefore, the gap between the cages 1 and 1 can be reduced to half that of the conventional one, and the area indicated by - in Fig. 2 can be saved.
This is the only area where the elevator shaft space can be made smaller.

In addition, what is shown in FIG. 3 shows an embodiment in which the cages 1 and 1 are adjacent to each other on the side and a counterweight 6°6 is arranged in the gap between them. Shaft space can be downsized.

Furthermore, in any of the embodiments, in addition to the conventional method, guide rules can be shared and the number of brackets can be reduced, so that material savings can be achieved.

Claims (1)

[Scope of utility model registration request] In an elevator shaft where a plurality of cars are arranged in pairs and adjacent to each other, each counterweight of two adjacent cars is placed between the two cars in a vertical line perpendicular to the direction in which the cars are lined up. The elevator counterweight installation structure is characterized by buttons placed horizontally within the surface and arranged vertically freely.
