2. Description of the Related Art Recently, a new transportation system has been developed and operated as a transportation means to replace railways and automobiles. In a new transportation system, usually, as shown in FIG. 3, a traveling roadbed 2 is provided on the foundation roadbed 1 so as to be higher than the basic roadbed 1, and the vehicle 3 is caused to travel on the traveling roadbed 2. The steered wheels 4 of the vehicle 3 are operated by a bar 5, and the bar 5 is provided so as to cross the traveling roadbed 2. Wheels 6 are attached to both ends of the bar 5 with their axes oriented in the direction of gravity. These wheels 6 are fastened to the inside of side walls 7 provided vertically on both edges of the foundation roadbed 1 by rail fastening. It is in constant contact with a fixed guide rail 9 via a device 8. That is, in the new transportation system, the guide function of the pair of guide rails 9 is used to prevent the vehicle 3 from coming off the traveling roadbed 2, and the guide function prevents the vehicle 3 from falling in the width direction.

By the way, in such a system, an H-section steel (H150 × 150) is usually used as the guide rail 9. When the guide rail 9 is laid, conventionally, as shown in FIG. 4, a guide vehicle 9 such as a truck is used to transport the guide rail 9 to the laying place, and as shown by a two-dot chain line arrow 13, Is carried by the operator to the side wall 7 and then attached to a predetermined rail fastening device 8.

However, the standard unit of H-section steel has a length of 10 to 15 m, and the weight of one unit is 300 to
It can reach 500 kg. For this reason, the worker is not only a heavy worker, but also there is a risk that the worker may get stuck at the step between the foundation roadbed 1 and the traveling roadbed 2, which is very dangerous.
Further, not only the movable range of the transport vehicle 12 is limited by the traveling roadbed 2, but all of the work is manual work, which causes a problem of low work efficiency.

[0005]

As described above, the conventional guide rail mounting method has problems in that the work is dangerous and the work efficiency is extremely poor. Therefore, an object of the present invention is to provide a guide rail attachment device that can perform a safe and efficient work.

[0006]

In order to achieve the above-mentioned object, a guide rail mounting device according to the present invention is a bogie that is arranged so as to be movable along a roadbed, and is movable in the car in the vehicle width direction. The rail mounting table is mounted so as to be vertically movable and tiltable, and means for adjusting the position, height and tilt of the rail mounting table in the vehicle width direction.

[0007]

As a result of taking the above measures, the following effects occur. The rail mounting table mounted on the trolley has not only the function of mounting the guide rail but also the function of being movable in the vehicle width direction, vertically movable, and tiltable. Therefore,
By combining these functions, it is possible to mount the guide rails directly on the rail mounting device while the guide rails are still loaded on the rail mounting base, and to perform the mounting work safely and efficiently. You can
