Description

The present invention relates to a hoistway structure of a circulating elevator and an elevator arrangement structure in which a hoistway is formed in a loop shape and a plurality of cars perform a circulating operation in one direction. It is about.

[Conventional technology]

A conventional elevator is generally one in which one car is provided in one hoistway and the car is hung by a rope to move up and down in the vertical direction.

However, since such a rope type elevator does not have a very large transport capacity per hoistway area, a very large space is required to carry a large amount of transportation, and therefore, especially for skyscrapers and deep underground stations. It was not very suitable as a lifting equipment that requires a large amount of transportation like.

For this reason, recently, so-called circulating elevators have been proposed, such as Japanese Utility Model Laid-Open No. 61-148875 or Japanese Patent Laid-Open No. 61-291383, for the purpose of obtaining a large transportation capacity in a small space. .

The circulation type elevator, as shown in FIG.
The elevator shaft is separated into an ascending / descending hoistway 11 and a descending / descending hoistway 12, and traverse paths 13 and 14 that connect the upper and lower ends of the elevator shaft are provided to form the hoistway in a loop shape. It is configured so as to circulate in one direction in the hoistway.

[Problems to be Solved by the Invention]

By the way, in the above-described circulation type elevator, since each hoistway has an independent structure, the wind noise becomes loud when the speed of the car becomes high, and some measure is required. In particular, in the case of a system in which a car is run by a linear motor, it is generally necessary to reduce the gap between the side of the car and the inside of the tower in order to improve electromagnetic coupling, and the wind noise further increases. For this reason, the partition provided between the ascent and descent hoistways is eliminated,
That is, it is conceivable to remove all but the members necessary for the operation of the elevator to form a so-called open hatch to reduce wind noise.

However, in order to secure a larger amount of transportation capacity, when installing a plurality of such circulating elevators adjacent to each other, it may not always be sufficient to simply open the hatches between the hoistways. It was This is the fourth
It will be described with reference to the drawings.

FIG. 4 shows, as an example, a plane of an elevator landing and a cross section of a shaft on a certain floor when two sets of circulating elevators are installed in the same shaft.
Reference numeral 20 is an elevator shaft, 21a is a hoistway dedicated to raising the first circulation type elevator, 21b is a hoistway dedicated to descending the same, 22a is a hoistway dedicated to raising the second circulation type elevator, 2
2b is also the hoistway dedicated to its descending, and 23 and 24 are elevator halls.

In the configuration shown in FIG. 4, if the partitions between the hoistways are eliminated and all open hatches are provided as described above, the wind noise will be reduced compared to the case where the hoistways are all partitioned to form individual elevator shafts. It can be expected to reduce. However, since many cars run in one direction in the hoistway in the circulation type elevator, if hoistways for the same direction are arranged adjacent to each other as shown in FIG. There are many opportunities for the cars to run side by side, and if they run side by side, there is a problem that the wind noise will be extremely loud even if the hatch is open.

Further, in the case of a system in which a car is run by a linear motor, it is necessary to separate the adjacent circulating elevators to some extent in order to prevent mutual influences between the adjacent circulating elevators. However, in that case, if all the open hatches are used to prevent wind noise as described above, the area of the shaft will increase by the distance, and the effective floor area of each floor will decrease accordingly. there were.

The present invention has been made in view of the above problems, and when installing a plurality of circulating elevators adjacent to each other, to prevent wind noise during car running as much as possible, and to minimize the space of the hoistway. The purpose is to make the effective floor area of the building as large as possible.

[Means for Solving the Problems]

In order to achieve the above object, the present invention arranges the ascending and descending hoistways for exclusive use of each circulation type elevator so that hoistways for different directions are adjacent to each other, and all the hoistways are arranged between them. Open circulation hatches should be installed apart from each other so that they are not magnetically affected by each other, and the hoistways of adjacent circulation elevators should not be open hatches, but only for raising within the same circulation elevator. It is characterized by an open hatch only between the hoistway and the hoistway dedicated to descending.

[Action]

According to the above configuration, since all the hoistways are open hatches, the wind noise is greatly reduced, and the operating directions of the cars are all opposite between adjacent hoistways, so the cars are in the same direction. There are no cases of wind noises running side by side.

Further, according to the above configuration, since an open hatch is provided between the ascending / descending hoistway and the ascending / descending hoistway in one set of circulation type elevators, the wind noise is sufficiently reduced, and moreover, between the hoistways of adjacent circulation type elevators. Does not have an open hatch, so not only does the wind noise due to the cars running side by side in the same direction do not occur, but the space between the revolving elevators becomes the effective floor area of the building. Is used for various other purposes.

〔Example〕

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a diagram showing a hoistway and an arrangement structure of a circulation type elevator according to the present invention, which is a view corresponding to FIG. 4, and the same elements as those in FIG. 4 are all denoted by the same reference numerals.

As is apparent from FIG. 1, the difference from the configuration of FIG.
For the first circulation type elevator and the second circulation type elevator, the arrangement of the ascending hoistway and the descending hoistway is reversed, that is, the adjoining hoistways have all the front, rear, left and right cars traveling in opposite directions. It is arranged. By doing so, in addition to the effect of reducing wind noise by making all the hoistways open hatches, a large wind noise caused by cars running side by side in the same direction between adjacent hoistways. Can be completely eliminated.

FIG. 2 is a view showing another embodiment of the hoistway and the arrangement structure of the circulation type elevator according to the present invention, and the same parts as those in FIG. 4 are designated by the same reference numerals.

In FIG. 2, when a car is run using a linear motor in particular, the circulating elevators are installed at a certain distance so as not to be magnetically affected by each other. In the inside, between the ascending-descending hoistway and the ascending-descending hoistway, there is an open hatch to reduce wind noise, and there is a considerable reduction effect of only one open hatch, so the first circulation type There is no open hatch between the elevator and the second circulating elevator, that is, the shaft 20A of the first circulating elevator.
And the shaft 20B of the second circulation type elevator are independent of each other so that the space in the shaft does not increase more than necessary. Therefore the space between this
The 25 can be used as a passage, a toilet, a storage space, and various other purposes.

In the above description, the case where two sets of circulating elevators are installed has been described, but it goes without saying that the present invention can be applied as it is to the case where three or more sets of circulating elevators are installed.

[Advantages of the Invention] As described above, according to the above-described configuration, in addition to the reduction of wind noise due to the open hatch between all the hoistways, the arrangement of the hoistways has been devised to reduce the noise level of the car. Wind noise due to running can also be prevented, and the wind noise can be maximally prevented with a very economical structure.

Further, according to the above-mentioned configuration, since the ascending-descending hoistway and the descending-descending hoistway in the same circulation type elevator are combined into an open hatch, it is possible to sufficiently reduce wind noise, and at the same time, adjoin them. Even if a certain distance is required between the circulation type elevators, it is possible to prevent the effective floor area of the building from decreasing, and at the same time prevent wind noise and save space in the elevator shaft. .
