BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a monorail device installed in a vertical meandering and horizontally bent portion of a tunnel among transporting devices for a tunnel.

[0002]

2. Description of the Related Art Conventionally, in a dam corridor provided for dam inspection, there is a place where a landing (horizontal portion) is provided in the middle of a staircase (inclined portion). When laying a monorail device in a corridor where the ascending and descending stairs to the landing are shifted horizontally at the landing, it is practically difficult because the monorail needs to be supported horizontally at the landing and bent at a right angle. And therefore FIG.
As shown in the figure, the monorail 5a is arranged on the ascending stair 1a side of the corridor 17, the monorail 5b is arranged on the descending stair 1b side, and the moving rail 8 is arranged on the landing 2; The cabin is running so that it is connected to the cabin.

[0003]

Problems to be Solved by the Invention In the above-mentioned monorail device, since the moving rail 8 is installed horizontally, the ends of the connected monorails 5a and 5b have a large bending angle A (bending radius B). Needs to be reduced), and processing and mounting work are troublesome. In addition, since the curve becomes steep, vibration and impact of the cabin increase when passing through this portion, which causes discomfort to the occupant. Therefore, a monorail device which facilitates installation of the monorails 5a and 5b and facilitates cabin traffic is provided.

[0004]

Means for solving the problem The means of the present invention for achieving this object is provided with a landing, and the landing is inclined in the same direction.
Providing a rising stair and a descending stair, and
Stairs and descending stairs are set to be shifted laterally at the landing
In the audit corridor of the tunnel-shaped dam,
An upper monorail and a lower monorail are installed on the descending stairs, respectively.
And move the moving rail to the landing
Or move laterally to communicate with the lower monorail
And the moving rail is fixed in an inclined state.
And move the ends of the upper and lower monorails to the moving rails.
And formed in an arc by a smoothly continuous bending angle,
Cabins that can be placed on the moving rail
It is characterized by running on a monorail .

[0005]

[Function] With this configuration, it is bent.
In the audit gallery of the tunnel
The moving rail arranged in an inclined state is installed so that it can move in the horizontal direction.
The upper rail is higher than when the moving rail is mounted horizontally.
The bending angle of the lower end of the no rail and the upper end of the lower monorail can be reduced (bending radius is increased) ,
Cabins running on monorails are also transported by moving rails.
It can be sent and run on the next monorail.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the accompanying drawings. As shown in FIG. 1, a landing (horizontal portion) 2 is provided between the ascending stairs 1a and the descending stairs 1b of the corridor 17 in the tunnel.
As shown in FIG. 2, the ascending stairs 1a and the descending stairs 1b are provided in the landing 2 so as to be shifted in the lateral direction. In the whole corridor 17, there are many places meandering up and down, stairs,
At a place with a landing, it will bend horizontally.

Upper and lower monorails (5a, 5b) are attached to the ceilings of the ascending stairs 1a and the descending stairs 1b, and the upper and lower monorails (5a, 5b) facing the landing 2 are provided.
The end of b) is formed with a smaller bending angle A (larger bending radius B) than in the past, and is installed with a space in the lateral direction. The bogie moving device 6 is attached to the ceiling of the landing 2 with the lower end of the upper monorail 5a in contact with one side and the upper end of the lower monorail 5b in contact with the other side. A suspension truck 4 runs on the upper and lower monorails (5a, 5b) and a moving rail 8 described later, and a cabin 3 is provided on the suspension truck 4 in a suspended state so that an operator or the like can board.

As shown in FIGS. 2 and 3, the carriage moving device 6 includes a pair of carriage rails 13 supported by a support member suspended from the tunnel ceiling and extending in the horizontal direction. A trolley 9 movably mounted,
It is roughly composed of a moving rail 8 supported by a support member hanging down from the carriage 9 and fixed in an inclined state, and a driving device 7 for driving the carriage 9.

The bogie rail 13 has a configuration in which rails having a U-shaped cross section are opposed to each other, and the distance between them is kept constant by a side plate 13a.

The trolley 9 is located between a pair of trolley rails 13 and has wheels 12 rotatably mounted on side surfaces thereof mounted on the trolley rails 13. In addition, on the trolley 9,
A spindle nut 11 having a screw hole oriented in a horizontal direction is fixed, and a spindle 10 having a male screw rotatably supported on a side plate 13 a of a bogie rail 13 is screwed into the spindle nut 11.

A pulley 16 is mounted on the spindle 10, and a drive pulley 14 is attached to a motor shaft of an electric motor as the drive device 7 fixed on the rail 13 for the carriage.
Is attached, and the rotation of the driving device 7 is transmitted to the spindle 10 by the belt 15 spanned over both pulleys.

Next, a case where the cabin 3 descends along the upper monorail 5a will be described. The cabin 3 smoothly travels along the lower end of the upper monorail 5 a having a small bending angle A and rides on the moving rail 8. As a result, the driving device 7 of the carriage moving device 6 is started, and the driving pulley 14 is rotated to rotate the spindle 10.

When the spindle 10 rotates, the spindle 1 rotates.
The spindle nut 11 connected to the spindle 0 moves in the direction of the lower monorail 5b. At the same time, the bogie 9 fixed to the spindle nut 11 moves along the bogie rail 13 via the wheels 12 of the bogie 9. By the movement of the carriage 9, the movement rail 8 attached to the carriage 9 of the carriage moving device 6 is connected to the upper end of the lower monorail 5b formed at a relatively small bending angle A, and the cabin 3 is moved downward from the movement rail 8 It will descend over the monorail 5b smoothly.

[0014]

[Effect of the Invention] Since the present invention has the above configuration, the bending angle of the connection end of the upper and lower monorails can be reduced (bending radius is increased), and the bending and working of the monorail can be easily performed. Become. Also, when the cabin moves between the upper and lower monorail and the landing (horizontal part), the cabin runs smoothly, and the vibration and impact on passengers in the cabin are reduced compared to the conventional one. It will be a comfortable ride. And since the moving rail can transport the cabin in the horizontal direction,
The cabin can be moved along the horizontal part of the audit corridor.
