2. Description of the Related Art In recent years, for example, a construction of a super high-rise building having a length of about 1000 m or more has been proposed. As a transportation means for efficiently carrying a large number of personnel accommodated in the super high-rise building,
A self-propelled elevator has been proposed in place of the conventional rope-type elevator.

An already proposed self-propelled elevator of this type is constructed as shown in FIG.

That is, in FIG. 3, a pair of hoistways 2 and 3 are vertically arranged side by side in a high-rise building 1. On both sides of the hoistways 2 and 3, fixed rails 4a for vertical movement are provided. 4b
And 5a and 5b are attached. Further, primary rail coils 6a, 6b of the linear motor are attached to the fixed rails 4a, 4b and 5a, 5b for vertical movement, respectively. Sideways 7, 8
Are provided so as to communicate with each other to form a loop. Further, rails 9 and 10 for vertical movement and a primary coil (not shown) of a linear motor are horizontally laid horizontally in the middle of the vertical movement paths 7 and 8, respectively. At the bottom portions 2a, 3a of the hoistways 2, 3 located on both sides of the rail 9, for example, lifter devices 11, 12 by hydraulic cylinder devices mount the car 13 on the hoistway 2,
It is provided so as to support when it descends to the lowest end of No. 3. Furthermore, the car 13 is provided with a secondary side conductor (secondary side conductor) 14 of the linear motor so as to face the primary side coils 6a and 6b of the linear motor. Wheels 13a are attached to the lower part of the.

Therefore, the above-mentioned self-propelled elevator is
The car 13 is placed by the lifter device 11 in advance, and the car 13 is lifted up to the lowermost end of the hoistway 2 and stands by.

Next, when the car 13 is energized, the secondary side conductor 14 of the linear motor is lifted by the thrust of the primary side coil 6a of the linear motor to stop at a predetermined floor and the passengers. When the car 13 rises up to the uppermost end of the hoistway 2 after getting on and off the car, the car 13 moves along one of the lateral moving rails 10 of the lateral traveling path 8 to the other hoistway 3 described above. After moving in
After the secondary conductor 14 of the car 13 descends due to the primary coil 6b of the linear motor and thrust to stop at a predetermined floor to get on and off passengers, the car 13 is at the bottom end of the hoistway 3. When it descends to the section, the car 13 is moved by the linear motor along one lateral movement rail 9 of the lateral traveling path 7 to the other hoistway 2.

[0007]

However, the above-mentioned self-propelled elevator is provided with the lateral movement rails 9 and 10, and the primary side coils of the linear motor are attached to the lateral movement rails 9 and 10. Both hoistways 2,
Since the lifter devices 11 and 12 are installed in the lower part of 3, not only the structure becomes complicated, but also the operation of changing the direction of the car 13 requires complicated control means.
Since the horizontal movement rails 9 and 10 and the primary side coil of the linear motor are additionally installed in the high-rise part of the high-rise building, the construction period becomes long and there is a problem in safety of work at high places.
It is difficult to provide at low cost.

The present invention has been made in view of the above-mentioned circumstances, and it is intended to simplify the structure, smooth the operation of changing the direction of the car, shorten the construction period, and improve the work safety. The purpose is to provide an elevator that has been changed to.

DISCLOSURE OF THE INVENTION The present invention relates to an elevator in which a car equipped with a secondary-side conductor of a linear motor elevates and traverses a hoistway and a lateral traveling path of a building. The fixed rails for vertical movement are attached to the both hoistways, and the fixed rails for vertical movement are provided so as to form a loop by connecting the lateral travel paths to the upper and lower portions of the both hoistways. Each pair of turning rails is rotatably pivoted to each of the lateral traveling paths on the extension line of, and each primary side coil is attached to each of the fixed rails for vertical movement and each pair of turning rails, and the secondary side of the car. They are attached so as to face the conductors.

[0010]

According to the present invention, when the linear motor is driven by energizing the car, the car is lifted by the thrust of the secondary side conductor and the primary coil to stop at a predetermined floor. After getting on and off the passengers and raising this car to the uppermost end of the hoistway, after transferring this car to one of the vertically positioned turning rails, each turning rail is rotated about 90 degrees around the spindle. Turn the car to a horizontal level and stop it. Then, the car travels along each turning rail with a linear motor and stops.
After turning about 0 degrees to make it vertical, it descends due to the thrust of the secondary side conductor and the primary side coil and stops at a predetermined floor to get on and off passengers. When it descends to the lower end, it transfers the car to the other vertically positioned turning rail, turns each turning rail about 90 degrees around the spindle, stops it horizontally, and stops each car. The rails are run by a linear motor and stopped, and each of the swing rails is swung about 90 degrees around the support shaft to stop vertically and return to the original position to change the direction of the car. It is intended to make work smoother, shorten the construction period, and ensure work safety at high places.
