DETAILED DESCRIPTION OF THE INVENTION

 [Object of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a double car elevator.

[0002]

2. Description of the Related Art In recent years, with the emergence of high-rise buildings and super-large buildings, it has become difficult to carry many people efficiently only with a bank structure divided from a conventional low-rise bank into a high-rise bank.
A sky lobby elevator that operates between the building and a relay lobby in the middle of the building has appeared.

The sky lobby elevator is large and operates between fixed floors. Therefore, as shown in FIG. 10, an elevator having a special structure in which two cars are provided by suspending a car instead of a counterweight as shown in FIG. (Hereinafter called double car elevator).

FIG. 10 shows a conventional double car elevator, which comprises two cars 1 and 2, a main rope 3 connecting them, and a hoisting machine 4 for driving the same. The car 1, 2
Moves on the hoistway 5.

[0005]

The advantage of the double car elevator is that it is possible to increase the transport capacity as a sky lobby elevator, but the disadvantage is that the cross section area of the hoistway is about twice that of the conventional elevator. is there. The present invention is a double car elevator in which the size of the hoistway is not increased as much as possible in order to solve the above problems. [Configuration of the Invention]

[0006]

SUMMARY OF THE INVENTION A hoistway is provided in which only an intermediate portion is inflated so that two cars of a double car elevator can rub against each other.

A guide rail for guiding a main rope is provided in a hoistway, and a movable beam to which the main rope is attached is fitted to the guide rail.
Further, a car is suspended from the movable beam via a free arm. On the other hand, a guide rail for traveling is provided along an inflated hoistway, and a roller guide of the car is fitted into the guide rail to guide the car to travel along the hoistway.

[0008]

With this configuration, the two cars can move up and down in the opposite directions, and can rub each other at the middle of the hoistway.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to the embodiments shown in FIGS.

A hoistway 6 bulging in the middle is provided. That is, there is no hoistway in which the cross section of the hoistway center is large enough that the two cars 1, 2 do not contact each other when they are rubbed by lifting and lowering, and the other places are of a normal size that allows only one car to pass through. It is a hoistway. The hoistway 6 is provided with two types of guide rails. That is, a guide rail 7 for guiding the main rope and a guide rail 10 for running the car. Two main rope guide rails 7 are provided for the cars 1 and 2 between the top and bottom of the hoistway. Fit the movable beam with the main rope into this,
Guide the main rope.

The guide rails 10 and 10 for running the car are formed as guide rails along the bend of the hoistway, and the running of the car moves along the hoistway by fitting the roller guides of the car into the guide rails. The two parts can be rubbed against each other.

A main rope 3 connecting the cars 1 and 2 is wound around a hoist 4 above the hoistway, and both ends are attached to movable beams 8 and 8, respectively. In the cars 1 and 2, the free arm 9 on the car is connected to the movable beam. That is, it becomes possible to considerably reduce the hoistway volume as compared with the conventional example. Particularly in a high-rise building, the portion requiring two hoistways is smaller than that of the whole building, and the effect is greater.

In FIG. 1, the movable beam 15 of the car 11 is located on the left side of the car 11. The movable beam 16 of the basket 12
Is located to the right of the car 12 on the contrary. This allows the main ropes 19 to connect the movable beams 15, 16 via the hoisting machine 14 without always touching either of the cars 11, 12.

Next, in FIG. 2, when the car 11 descends, the car 11 is on the left side in the central swollen hoistway by the guide rail shown in FIG. On the other hand, the car 12 is on the right with the ascent. This allows the cars 11 and 12 to rub each other at the center without hitting each other. Next, in FIG.
FIG. 5 shows a detailed view of a portion 5.

The movable beam 15 and the car 11 are connected by a free arm 20, and the movable beam 15 runs on guide rails 17A and 17B by a guide shoe. A main rope 19 is connected to the movable beam 15, and the movable beam 15 is moved up and down by rotation of the hoist 14. Next, the guide rail 3 for traveling
The shapes of 1 and 32 and their functions will be described. The car 11 is provided with upper and lower guide rollers 33 and 34, respectively.

On the other hand, the guide rails 31 and 32 for traveling are a guide rail 32 for a guide roller 33 and a guide roller 34.
Guide rails 31 are used on one side of the car 11. By installing these traveling guide rails 31 and 32 in the shape as shown in FIG. 5, when the car moves up and down, the car 11 can travel while always being horizontal as shown in FIG. FIG. 6 shows a detail of the guide roller.
Guide rollers 33A and 33B on the upper side of the car 11 run on guide rails 31A and 31B, respectively, and guide rollers 34A and
34B runs on 32A and 32B, respectively.

[0017]

According to the present invention, in a double car elevator system, the space in the building can be effectively used by taking up space for two cars only in the central part of the hoistway so that the space in the building can be used efficiently. Can do things.

Claims (1)

(57) [Claims] Claims: 1. In a double-cage elevator of a slidable type in which a car is attached to each of both ends of a main rope and two cars are lifted and lowered in one hoistway, only the size of a central portion of the lifting process is limited. The two cars are inflated to different sizes to form a hoistway, and a guide rail for the main rope and a guide rail for the car bent along the hoistway shape are provided in the hoistway. A double car elevator, characterized in that the space is connected to a movable beam guided by the rope guide rail via a free arm, and further, a car guide roller is fitted on the car guide rail to guide the car.
