JPH04129986A - Lift path and arrangement structure for circulative elevator - Google Patents

Abstract

PURPOSE:To decrease a wind noise as low as possible at the time of running of a cage by arranging an up-running exclusive use lift path and a down-running exclusive use lift path of each circulative elevator, so that the lift paths for respectively different directions are placed adjacent to each other, and also forming an open hatch between the lift paths. CONSTITUTION:In the first/second circulative elevators, up-running exclusive use lift paths 21a, 22a and down-running exclusive use lift paths 21b, 22b are arranged so that the lift paths are reversed, that is, all the adjacent lift paths are provided with a running direction of a cage reversely in right/left and front/ rear. In this way, generation of a large wind noise, caused by parallel running in the same direction of the cages between the adjacent lift paths, can be perfectly eliminated in addition to an effect of reducing a wind noise by forming an open hatch all between the lift paths.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a hoistway structure and an elevator arrangement structure for a circulating elevator in which the hoistway is configured in a loop shape and a plurality of cars circulate in one direction. It is related to.

[Conventional technology]

Conventional elevators generally have one car in one hoistway, and this car is suspended by a rope to be raised and lowered in the vertical direction.

However, such rope-type elevators do not have a large transportation capacity per hoistway area, so they require a very large space to transport large quantities, and are therefore particularly suitable for use in super-tall hills and deep underground stations. It could not be said that it was very suitable for lifting equipment that required large amounts of transportation.

For this reason, recently, with the aim of obtaining large transportation capacity in a small space, for example,
A so-called circulating elevator has been proposed as disclosed in Japanese Patent Application Laid-Open No. 6L-291383.

An example of a circulating elevator is shown in Figure 3.
The elevator shaft is divided into a hoistway 12 exclusively for ascending and a hoistway 12 exclusively for descending, and furthermore, transverse passages 13 and 14 are provided to connect the lower ends of these hoistways 13 and 14, respectively, to configure the hoistway in a loop shape. The car 10 is configured to circulate in one direction within the same hoistway.

[Problem to be solved by the invention]

By the way, in the above-mentioned circulation type elevator, each hoistway has an independent configuration, so when the car speed increases, wind noise becomes louder (some kind of countermeasure is required. Especially with linear motors) In the case of a system in which the car runs, 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, which also increases wind noise. Eliminating the partition between the elevator and the descending hoistway,
In other words, it is possible to reduce wind noise by removing all parts other than those necessary for elevator operation to create a so-called open patch.

However, when installing multiple sets of such circulating elevators adjacent to each other in order to secure a larger transport capacity, it may not always be sufficient to simply create an open gap between each hoistway. Ta. This is the fourth
This will be explained using figures.

Figure 4 shows the plane of the elevator landing and the cross-section of the shaft 71 for each floor when two sets of circulating elevators are installed in the same shaft. Elevator shaft, 21a is a hoistway exclusively for the upward movement of the first circulating elevator, 21b is a hoistway exclusively for the downward movement thereof, 22a is a hoistway exclusively for the upward movement of the second circulation elevator, 22b is a hoistway exclusively for its downward movement, 23 and 24 are elevator halls.

In the configuration shown in Fig. 4, if the partitions between each hoistway are eliminated and all are made into open hatches as described above, wind noise will be reduced compared to the case where all the partitions between each hoistway are partitioned to form separate elevator shafts. can be expected to decrease. However, in a circulating elevator, a large number of cars travel in one direction in the hoistway, so if the hoistways for the same direction are arranged adjacent to each other as shown in Figure 4, the cars in the hoistway run in the same direction between adjacent hoistways. There are many opportunities for the cars to run side by side, and if they run side by side, there is a problem in that wind noise becomes extremely loud even if the car has an open haunch.

In addition, in the case of a method in which the car is run by a linear motor, it is necessary to provide a certain distance between adjacent circulation elevators in order to prevent mutual magnetic influence between them. However, in that case, if all the hatches are made open to prevent wind noise as mentioned above, the area of the shaft will increase by the distance they are separated.
There was a problem in that the effective floor area of each floor decreased accordingly.

The present invention has been made in view of the above-mentioned problems, and when multiple circulation type elevators are installed adjacent to each other, it is possible to prevent wind noise during car running as much as possible, and to minimize the space in the hoistway. The purpose is to make the effective floor area of the building as large as possible.

[Failure to solve the problem]

In order to achieve the above object, the present invention has the following features: (1) The hoistway exclusively for raising and the hoistway exclusively for lowering of each circulation type electric heater are arranged so that the hoistways for different directions are adjacent to each other, and the hoistways are arranged so that the hoistways for different directions are adjacent to each other. All have open hatches ■Each circulation type elevator shall be installed at a distance to the extent that they are not affected by each other magnetically, and there shall be no open hatch between each hoistway of adjacent circulation type elevators.
This system is characterized by an open hatch between only the upward hoistway and the downward hoistway within the same circulation elevator.

[Effect]

According to the configuration (■) above, all the spaces between each hoistway are open-circuited, so wind noise is greatly reduced, and all cars are driven in opposite directions between adjacent hoistways.
There are no cases where the cars run side by side in the same direction and generate wind noise.

In addition, according to the configuration in item 1, ■ in the circulation type electric hake of group -, an open hatch was used between the second hoistway for ascending and the hoistway for descending, so the wind noise was reduced by -1 minute. Since there is no open hatch between the hoistways of circulation type elevators, there is no wind noise caused by cars running in parallel in the same direction, and the space between each circulation type elevator is the effective floor area of the building. It can be used as a passageway, storage space, or 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 arrangement structure of a circulating elevator according to the present invention, and is a diagram corresponding to FIG. 4, and all the same parts as in FIG. 4 are designated by the same reference numerals.

As is clear from Figure 1, the differences from the configuration in Figure 4 are as follows:
In the first circulation type elevator and the second circulation type elevator, the arrangement of the hoistway exclusively for ascending and the hoistway exclusively for descending is reversed, that is, the adjacent hoistways are all arranged in the direction in which the car is running, or in the opposite direction. This is because it has been placed. By doing this, in addition to the effect of reducing wind noise due to all open hatches between each hoistway, it also reduces the large wind noise caused by cars running in parallel in the same direction between adjacent hoistways. The occurrence of can be completely eliminated.

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

In Figure 2, especially when a linear motor is used to run a car, adjacent circulation elevators are installed with a certain amount of space between the corners to prevent mutual magnetic influence, while each circulation elevator is Type Elm - In one beta, an open hatch is used between the hoistway exclusively for ascending and the hoistway exclusively for descending to reduce wind noise.
Open hatches in some places have a significant reduction effect, so open hatches are installed between the first circulation type elevator and the second circulation type elevator.

The shirt of the first circulating elevator
-20A and second circulating elevator shirt 1-20
B and B are each configured independently so that the space within the shaft does not increase more than necessary. Therefore, the space 25 between them can be used as a passage, for installing a 1-ile, as a storage space, and for various other purposes.

Although the following explanation deals with the case where two sets of circulation elevators are installed, it goes without saying that the present invention can be applied as is to the case where three or more sets of circulation elevators are installed. .

〔Effect of the invention〕

As shown in [2] above, according to the configuration described in (2) above, in addition to reducing wind noise by creating an open hatch between each hoistway, the arrangement of the hoistways has been devised so that the cars can run parallel to each other. It is also possible to prevent the generation of wind noise caused by wind noise, and it is possible to prevent wind noise to the maximum extent with a very economical configuration.

In addition, according to the above-mentioned configuration (■), since the two hoistways for raising and lowering and the hoistways for lowering in the circulation type electric heater are set as an open hatch, they are sufficiently effective in reducing wind noise. At the same time, even if a certain distance is required between adjacent circulating elevators, the effective floor area of the building can be prevented from being reduced, thereby simultaneously preventing wind noise and saving space in the elevator shaft. can be achieved.
