Description

{Moving Eleventure Slope, HORIZONTAL, AND TWIST SECTION}

The present invention is installed in a railroad historic passage and a transfer passage of a subway to allow passengers to ride on a slope section, a horizontal section, a direction change section, and a twist section so that a disabled person, a child, a pregnant woman, A slope section, a horizontal section, a direction switching section, and an elevator for moving a twist section, which enable use of a railroad or a subway.

Generally, in the history of railway and subway, a vertical section is used for elevating facilities, a slope (step) for which there is no elevating facility, and a building structure is formed for moving on foot in the horizontal section.

The handicapped person carrying an electric wheelchair can not move the stairs section of the pedestrian passage of the escalator, and the wheelchair lift can be carried by a single person.

Most of the new buildings have moving walkways and escalators. However, there is a problem that it is difficult to install the moving walk or escalator in the old passage connecting the old history without elevator.

If a person with a disability using a railway or a subway, a child, a pregnant woman, or an elderly person goes up and down the horizontal and inclined stairs of 500m to 1,000m above the transfer section, the transfer will be delayed due to mental or physical pain or congestion. There is a problem of not being able to transfer.

To solve this problem, the elevator having the vertical, horizontal and inclined moving sections of the prior art for solving such a problem is disclosed in Japanese Patent Application No. 10-1400806 (May 22, 2014), and includes an elevator car and a vertical passageway And a horizontal guide portion for guiding the lift vehicle in a horizontal direction in association with a vertical passage provided with the vertical movement portion, wherein the vertical guide portion includes: A rotary shaft coupled to a lower portion of the connection shaft; a hydraulic piston rotating the rotary shaft to be fixed to the elevating frame; A first seat frame on which the wheels of the vehicle are seated, and a hydraulic pressure fixing stopper mounted on the first seat frame for interrupting the wheels, The stopper includes a body provided at a central portion of the first seat frame and a support member protruding from both side portions of the body to support the outer side of the wheel and to be vertically and horizontally rotated.

However, in the conventional elevator as described above, since the elevator car is driven by the wheels of the elevator car, it is difficult to accurately move the elevator car.

In addition, the conventional elevator can not control the elevation of the elevator car, so that it can not be used in a place where the height of the passage is low.
