The first traveling rack 5 is attached continuously or in a range exceeding the entire length. The horizontal curved portion 4D is attached to the other side edge of the upper surface flange 4b in a range in which the horizontal curved portion traveling rack 6 which is the second traveling rack exceeds the entire length of the horizontal curved portion 4D.

The drive carriage 1 and the driven carriage 3 are guided by traveling rails 4 and can travel freely on the traveling frames 1a, 2a.
And the platform parts 1b and 2b supported on the traveling frames 1a and 2a via the attitude control devices 7 and 7, respectively. Each of the traveling frames 1a and 2a is provided with a main traveling wheel 11 and an auxiliary traveling wheel 12 that come into contact with the traveling surface 4a, and a pair of left and right floating preventing rollers 13 that come in contact with the lower surface of the upper surface flange 4b. At the same time, side rollers 14 that contact the connecting member 4c of the traveling rail 4 from both sides are provided so as to be movably guided to the traveling rail.

A safety fence 16, a seat 17, and a controller 19 are mounted on a boarding platform 15 of the loading platforms 1b and 2b, and the posture control device 7 responds to the inclination of the curved portion of the traveling rail. The elevator 15 is held in an upright posture, and the platform 15 is rotatably supported by the traveling frames 1a and 2a via a posture control shaft 18 in a horizontal direction orthogonal to the traveling rails 4 and is supported by a controller 19. Based on the data input in advance and the detection value of the inclination detector (not shown), the attitude control motor 20 with a speed reducer is driven to rotate the boarding / alighting platform 15 via the attitude control shaft 18, thereby performing a vertical bending. Corresponding to the inclination of the traveling rail 4 in the portion 4C, the loading platform portions 1b and 2b can be held in the upright posture.

As shown in FIG. 1, the traveling frame 1a of the drive carriage 1 can mesh with the first traveling rack 5 on the horizontal drive shaft 21 on which the main traveling wheels 11 are rotatably supported via bearings. The first traveling pinion 22 is attached. The traveling device 23 that rotationally drives the first traveling pinion 22 includes a gear box 24 on one end side of the horizontal drive shaft 21.

When an occupant or a load is placed on the loading carriages 1b and 2b of the driving carriage 1 and the driven carriage 3 stopped on the horizontal linear portion 4A of the traveling rail 4, the passenger riding on the driving carriage 1 operates the operating device 19a.
Thus, the traveling device 23 is operated to activate the traveling motor 24. Then, the horizontal drive shaft 21 is rotationally driven via the gear box 24a to drive the first traveling pinion 22, and the horizontal linear traveling rack 5A receives a reaction force to start the drive carriage 1. Even if the tunnel T moves from the vertically curved portion 4B of the traveling rail 4 that inclines upward or downward to the inclined straight portion 4B, the traveling force of the traveling motor 24 causes the first traveling pinion 22 to vertically curve the first traveling rack 5. The traveling rack 5C and the inclined straight portion traveling rack 5B are transmitted and driven. In the vertical bending portion 4B, the attitude control motor 20 of the attitude control device 7 is driven according to the tilting of the traveling frames 1a and 2a corresponding to the vertical bending portion 4B,

According to the above-described embodiment, in the horizontal curved portion 4D of the traveling rail 4, the second traveling pinion 28 is meshed with the horizontal curved traveling rack 6 provided on the side surface of the traveling rail to drive the traveling rail 4, Since the first traveling rack 5 attached to the upper surface of is removed, the first traveling pinion 22 is in a free state, and the horizontal curved portion 4D can be smoothly traveled. In addition, the first traveling pinion 22 and the second traveling pinion 28 are interlockingly connected via the drive bevel gear 25 and the passive bevel gear 26, and are rotationally driven in synchronization by one traveling motor 24. Cost can be reduced and
The first traveling pinion 22 and the second traveling pinion 28 are meshed with the traveling racks 5 and 6 at the same time between the straight portion and the curved portion, so that the transition to the meshed rack can be performed easily and smoothly.

In the above embodiment, only the first traveling pinion 22 is engaged with the first traveling rack 5 by the horizontal and inclined linear portions 4A and 4B, but the second traveling pinion is engaged with the horizontal and inclined linear portions A and 4B. It is also possible to dispose a second traveling rack that meshes with the second traveling rack 28 and simultaneously allow the second traveling pinion 28 to mesh with the second traveling rack for traveling. As a result, a large traveling driving force can be supported, and it is most suitable for the inclined straight portion 4B having a large gradient that requires a large driving force.
