Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevating device which is installed in a skyscraper or the like and moves up and down at high speed to transport users.

[0002]

2. Description of the Related Art In a high-rise building or the like, an elevator device is installed as a lifting device for a building user to board and ascend and descend. This elevator system requires the cages to be raised and lowered at high speed in order to increase the transport capacity of building users per unit time and per unit area of building. In particular, ultra-high-rise buildings that are expected to be constructed in the future (for example, 500
In m), it is assumed that the maximum ascending / descending speed of the cage is 500 to 800 m / min in order to increase the transportation amount of the building user.

By the way, as an example, as shown in FIG. 7, when the cage rises from the ground floor to the uppermost floor at an ascending speed of 500 m / min, the rate of change in atmospheric pressure in the cage is converted into the rate of change in altitude difference. Then, it reaches 500m / min (50
0 m (altitude difference) corresponds to 44 mb (atmospheric pressure). Hereinafter, for the sake of convenience, the altitude difference (m) will be described).

However, the rate of change in altitude difference, which does not cause physiological and psychological discomfort (earache, dizziness, etc.) to the user who cannot adjust to changes in altitude difference when riding in this cage, is
Although there are individual differences, it is generally set at 150 m / min.

Therefore, as shown in FIG. 6, it is considered to stop the cage every time the altitude difference reaches 100 m and set the average rate of change in altitude difference to 150 m / min. However, this will increase the boarding time in the cage,
Dissatisfaction occurs for users who can adapt to changes in altitude difference.

In order to cope with this, as shown in FIG. 7, a high speed elevator H and a low speed elevator L can be provided so that the user can selectively board in accordance with the adaptability to changes in altitude difference. However, this requires two elevator installations.
The need to install a system will reduce the amount of transportation by building users per unit area of building. In addition, it is impossible to predict in advance the proportion of high-speed elevators and low-speed elevators to be used (ratio of acclimatizers and non-adapters), and therefore an appropriate transportation plan cannot be formulated.

[0007]

SUMMARY OF THE INVENTION In consideration of the above facts, the present invention is capable of transporting a user at a high speed by one system of lifting device, and is physiologically and physically effective even for a user who cannot adapt to a change in altitude difference. It is an object of the present invention to provide a lifting device that does not cause psychological discomfort.

[0008]

According to a first aspect of the present invention, there is provided an elevating and lowering device provided with a cage for raising and lowering a user, regardless of a change in atmospheric pressure outside the cage during ascent or descent. It is characterized in that it has a pressurizing / depressurizing means for changing the atmospheric pressure in the cage at a predetermined rate.

According to a second aspect of the present invention, there is provided an elevating device having an atmospheric pressure adjusting chamber in which a difference in atmospheric pressure from the inside of the gauge upon arrival or passage of a user seated in the cage is adjusted within a predetermined range. It has a feature.

According to a third aspect of the present invention, there is provided an elevating / lowering device, wherein the one air pressure adjusting chamber and another air pressure adjusting chamber, or the one air pressure adjusting chamber and another air pressure adjusting chamber, and an ordinary floor where the air pressure is not adjusted. It is characterized in that it has a shielding door which is provided at the entrance and exit of the room and which minimizes the pressure fluctuation in the pressure adjusting room due to the entrance and exit of the user.

[0011]

In the lifting device having the above-described structure, when the cage is lifted by a user, the rate of change of atmospheric pressure also changes according to the lifting speed. The rate of change in atmospheric pressure is usually the same outside the cage and inside the cage, but the pressurizing / depressurizing means changes the atmospheric pressure inside the cage at a predetermined rate regardless of the rate of change in atmospheric pressure outside the cage, that is, regardless of the raising / lowering speed of the cage. Change. The rate of change in atmospheric pressure is set so as not to cause physiological and psychological discomfort to users who cannot adapt to changes in atmospheric pressure difference.

Also, when the normal cage starts moving,
When stopping the movement, the ascending / descending speed becomes slow. For this reason, when the one-time ascent / descent distance is short, a large difference does not occur between the atmospheric pressure of the floor where the cage arrives and the atmospheric pressure inside the cage whose atmospheric pressure is adjusted by the pressurizing / depressurizing means.

[0013] However, if the length of one-time ascending / descending is long, the boarding time is long, so there is a large difference between the atmospheric pressure on the floor where the cage arrives and the atmospheric pressure inside the cage whose atmospheric pressure has been adjusted by the pressurizing / depressurizing means. Therefore, when the user gets out of the cage, he cannot adapt to the atmospheric pressure difference at the moment.

In order to deal with this, an atmospheric pressure adjusting chamber is provided on a predetermined floor or higher. This atmospheric pressure adjusting chamber is arranged so that a user in a cage passes or stays and moves to a floor whose atmospheric pressure is not adjusted. The atmospheric pressure in the atmospheric pressure adjusting chamber is adjusted so that the atmospheric pressure difference with the arrived gauge is within a predetermined range, that is, the atmospheric pressure difference can be adapted instantaneously. Therefore, the user can adjust to the atmospheric pressure in the floor where the atmospheric pressure is not adjusted by passing or staying in the atmospheric pressure adjusting chamber.

Also, the atmospheric pressure of the floor where the cage arrives,
If there is a large difference between the atmospheric pressure inside the cage whose pressure has been adjusted by the pressurizing / depressurizing means, a plurality of atmospheric pressure adjusting chambers are provided, and the atmospheric pressure adjusting chambers are sequentially passed or stayed so that the atmospheric pressure is not adjusted in the floor. Can adapt to atmospheric pressure.

Further, when a plurality of air pressure adjusting chambers are provided as described above, one air pressure adjusting chamber and another air pressure adjusting chamber communicating with the arrived cage, or one air pressure adjusting chamber and another air pressure adjusting chamber, A shield door is provided as an entrance / exit between the normal floor where the atmospheric pressure is not adjusted. This shield door minimizes pressure fluctuations in the pressure control chamber due to the user going in and out.

0B and 30C are connected to the control device 22 and maintain the atmospheric pressure of the atmospheric pressure adjusting chambers 24A, 24B and 24C at a predetermined value based on the signals output from the atmospheric pressure sensors 28A, 28B and 28C. ing. As shown in FIG. 5, the atmospheric pressure in the atmospheric pressure adjusting chamber 24A is set so that the difference from the atmospheric pressure in the cage 12 arriving on the floor F is 110 m or less in terms of altitude difference. Further, the atmospheric pressure difference between the atmospheric pressure adjustment chamber 24A and the atmospheric pressure adjustment chamber 24B and the atmospheric pressure difference between the atmospheric pressure adjustment chamber 24B and the atmospheric pressure adjustment chamber 24C are 110 m or less in terms of altitude difference. The atmospheric pressure difference between 24C and the floor F whose atmospheric pressure is not adjusted is set to be 110 m or less in terms of altitude difference.

As shown in FIGS. 1 and 4, a revolving door 32 as a shielding door is provided at the boundary between the pressure adjusting chambers 24A, 24B and 24C, and a boundary between the pressure adjusting chamber 24A and the floor F is provided. A revolving door 34 is arranged, and a revolving door 36 is arranged at the boundary between the atmospheric pressure adjusting chamber 24C and the floor F.

The revolving door 32 includes a revolving shaft 38 pivotally supported between a ceiling surface and a floor surface, six doors 40 projecting radially from the outer peripheral portion of the revolving shaft 38, and this door. It is composed of three arc-shaped cover portions 42 that cover the outer end portion of 40. The arrangement interval of the cover portions 42 is set to a size that allows the user to enter and leave each of the atmospheric pressure adjusting chambers 24A, 24B, 24C. As described above, by disposing the six doors 40, the user can enter and exit while sequentially partitioning the atmospheric pressure adjusting chambers 24A, 24B, and 24C, so that the atmospheric pressure adjusting chambers 24A, 24B, and 24C are hermetically sealed. The state is maintained. The number of doors is determined in consideration of the opening area of the cover 42, and is not limited to six.

The door 40 extends in the axial direction of the rotary shaft 38 toward the ceiling surface and the floor surface. This door 4
The upper and lower end portions of 0 are arranged with a gap that does not slide on the ceiling surface and the floor surface. Further, the outer end portion of the door 40 is arranged with a gap so as not to slide with the inner peripheral surface of the cover portion 42. As a result, the airtight state of each atmospheric pressure adjusting chamber 24A, 24B, 24C is always maintained.

The revolving doors 34 and 36 are four doors 4
It is composed of two. Also, the number of air pressure control rooms is designed to increase as one goes up to the upper floors of the building.

Next, the operation of the lifting device according to the present embodiment (when rising 500 m above the ground floor) will be described with reference to the flowchart shown in FIG.

At step 100, it is judged whether or not the raising button 50 is pushed and the door of the cage 12 is closed.
If the cage 12 door is closed, step 102.
Then, the pressurizing / depressurizing device 20 is driven to drive the cage 12 at a constant rate.
The pressure inside is reduced. As shown in FIG. 2, this pressurizing / depressurizing device 20 is connected to a control device 22, and is arranged at a constant rate of change (with respect to time) based on a signal from an atmospheric pressure sensor 18 arranged in the cage 12 for detecting atmospheric pressure. Since the pressure is reduced at the rate of change, the inside of the cage 12 does not need to be completely sealed.

Next, in step 204, the cage 12 is raised to the target floor, and in step 206, the door of the cage 12 is opened. At this time, the atmospheric pressure in the cage 12 is 150 m in terms of altitude difference, as shown in FIG. 5, so the altitude difference with the floor F is 350 m. Here, the atmospheric pressure adjusting chambers 24A, 24B and 24C are the pressurizing / depressurizing device 3
0A, 30B, 30C (see FIG. 4), 250
It is maintained at m, 350m and 450m. For this reason,
Since the instantaneous difference in altitude acting on the user can be suppressed to 110 m or less, even a user who cannot adapt to the change in atmospheric pressure does not feel physiological and psychological discomfort.

Now, the movement pattern of the user will be described. As shown in FIG. 4, there are three possible pressure difference change adaptability of the user. As shown by the chain line,
Users who have excellent ability to adapt to changes in atmospheric pressure,
The floor F is directly accessed through the revolving door 34 from A. Next, as shown by the broken line, the user who normally has the ability to adapt to changes in atmospheric pressure moves from the atmospheric pressure adjusting chamber 24A to the atmospheric pressure adjusting chamber 24C without staying in the atmospheric pressure adjusting chamber 24B, and from the revolving door 36 to the floor. You can access F. Further, a user who cannot adapt to the change in the atmospheric pressure difference moves from the atmospheric pressure adjusting chamber 24A to the atmospheric pressure adjusting chamber 24B as shown by the solid line.
Further, by sequentially moving from the atmospheric pressure adjusting chamber 24B to the atmospheric pressure adjusting chamber 24C, it is possible to access the floor F without feeling physiological and psychological discomfort. As described above, in the present embodiment, the user can access the target floor F according to the air pressure difference change adaptability even if the elevating device of another system is not arranged.

In the present embodiment, when descending from the uppermost floor, the user is sequentially pressurized in the atmospheric pressure adjusting chamber in advance and gets on the cage 12.

On the contrary, it is conceivable to provide an atmospheric pressure adjusting chamber on the ground floor. In this example, when going up in the cage 12, the pressure is successively reduced in the air pressure adjusting chamber before boarding the cage 12, and when going down from the top floor, the pressure is successively applied in the air pressure adjusting chamber installed on the ground floor. Become. However, it is not preferable to provide the atmospheric pressure adjusting chamber on the floor above the ground floor from the viewpoint of effective utilization of the building, so it is desirable to provide the atmospheric pressure adjusting chamber on the top floor.

Further, although the elevator has been mainly described in the present embodiment, the present invention is not limited to this, and is also applied to a transportation machine such as a ropeway and a cable car which moves between points having a large pressure difference. it can.
