2. Description of the Related Art Rail trucks are used for transporting steel strip coils and the like, and transport by a plurality of rail trucks (hereinafter referred to as "coil trucks") running on the same rail is an unspecified distance. In order to perform the operation efficiently, means for preventing interference between the coil carriages is provided.

For example, as shown in FIG. 4, a branching device 12 and an evacuation rail 13 are laid in a rail 11 and the coil carriage 1 is retracted by being drawn into the evacuation rail 13, or as shown in FIGS. A device for moving a simple coil carriage parallel to the direction of travel and retracting it.

FIG. 5 shows a coil bogie having a main rail 21 and a spare rail 22 laid on the same transition frame 23 and traveling on the main rail 21 previously aligned with the traveling rail 24. 1 is stopped, the transition frame 23 is moved, and the coil carriage 1 is retracted outside the traveling rail 24. At this time, the spare rail 22 is on the same line as the traveling rail 24, and another coil bogie can travel on the traveling rail 24 without any trouble.

However, a method of laying a turnout and an evacuation rail in the above-mentioned rail and retracting the coil bogie into the evacuation rail by the evacuation rail and the traveling rail in the turnout is described. Since the angle cannot be increased, the space A required for laying the evacuation rail becomes long as shown in FIG. 4, and it is difficult to add the space A to the existing rail equipment.

Further, as shown in FIG. 5, the side shift device for moving the transition frame and retracting the coil carriage is required to always maintain a constant length between the main rail laid on the transition frame and the spare rail. Therefore, a space where the spare rail is arranged, for example, a long space of about 4 m on the right side of the drawing is required in a state where the present rail coincides with the traveling rail. For this reason, it is often difficult to add this side shift device to existing rail equipment where the space in which the evacuation device can be installed is small.

[0008] As shown in Fig. 6, in a device in which a rail turner is arranged to move a coil bogie to an evacuation rail, a large load is applied to the rail turner, so that the rail turner requires high rigidity. In addition, since the coil bogie requires high stopping position accuracy at the rail turner position and a turning bogie, it is an expensive and complicated device.

Have been. Bending portions 4a and 4b are formed at both ends of the connecting rod 4, and when the rail base 2 is driven by an electric motor 6, which will be described later, on the transition rail 5 to the retreat position in the leftward direction in FIG. The other coil bogies 1 move on the spare rail base 3 without colliding with the bent portions 4a and 4b engaged with the bracket portions 2b and 3b, that is, with the coil bogie 1 stopped on this rail base 2. The rail base 2 and the spare rail base 3 are drawn with a sufficient distance therebetween.

Reference numeral 7 denotes a worm which is installed in parallel with the transition rail 5 and is connected to the electric motor 6. The worm 7 is screwed onto the main rail base 2. 2 moves between the running position and the retreat position along the transition rail 5. And this rail base 2 to the evacuation position
With the movement of the connecting rod 4, the projection 3e is formed on the lower surface of the spare rail base 3 so that the rail 3a laid on the spare rail base 3 moved leftward in FIG. In addition, a fixed stopper 5a is provided at a predetermined position in the movement range of the preliminary rail base 3 so as to abut on the projection 3e.
In addition, in the traveling position, the stopper 3d abuts on the wall 5b and stops on the spare rail base 3, and the stoppers 2d and 3d protruding on the respective side surfaces stop on the main rail base 2 which stops adjacently. It goes without saying that the laid rail 2 a coincides with the running rail 8.

The side shift device of the present invention has the configuration as described above. Usually, the rail 2a laid on the rail base 2 is on the same line as the running rail 8, and the coil carriage 1 runs. When the coil truck 1 traveling on the traveling rail 8 interferes, the electric motor 6 is rotated forward after the coil truck 1 stops at the main rail platform 2 and the main rail platform 2 is rotated.
Is moved along the transition rail 5 to the left in FIG. As the rail base 2 moves to the left, the bracket 2b first comes into contact with the bent portion 4a of the connecting rod 4, and the rail base 2 and the connecting rod 4 move to the left. When the rail base 2 is further moved to the left, the bent part 4b of the connecting rod 4 comes into contact with the bracket part 3b of the spare rail base 3, and the spare rail base 3 moves to the left in FIG. Start moving.

Then, the rotation of the electric motor 6 is stopped after the projection 3e comes into contact with the fixed stopper 5a and the spare rail base 3 is stopped in accordance with the running rail 8. At this time, the distance between the main rail base 2 and the spare rail base 3 is maintained by the connecting rod 4 so that the coil bogie 1 stopped on the main rail base 2 and the coil bogie 1 running on the traveling rail 8 do not interfere with each other. ing.

After another coil carriage 1 has passed the rail 3a laid on the backup rail 3, the electric motor 6 is rotated in the reverse direction to move the rail 2 to the right in FIG. After the rail base 2 comes into contact with the auxiliary rail base 3 via the stoppers 2d and 3d, the main rail base 2 moves to the right in FIG. Then, after the spare rail base 3 comes into contact with the wall 5b, the rotation of the electric motor 6 is stopped, and the movement of the main rail base 2 to the right in FIG. 1 is stopped. After that, the coil truck 1 stopped on the rail base 2 is driven to run on the traveling rail 8 again.

The side shift device of the present invention does not require a large evacuation space for the spare rail base when the rail on the rail base forms the same line as the running rail and the coil bogie travels on the rail. Approximately 40% more space for storing extra rails compared to conventional sideshift devices with equivalent capacity
The equipment cost can be reduced by about 50% as compared with an evacuation device using a rail turner having the same capacity as that of the evacuation device.

In this embodiment, a mechanism using an electric motor and a worm has been described as a drive mechanism for the rail base and the spare rail base.
It is also possible to mount the drive unit on a rail base to make it a self-propelled type. Further, in this embodiment, the case where two rail bases are used has been described, but it is also possible to provide a plurality of retreat positions by using three or more rail bases.

[0021]

As explained above, the side shift device for a track bogie according to the present invention follows the other rail tracks which are connected at variable distances by connecting rods when only one rail is driven. When the rail laid on one of the rails coincides with the traveling rail, the evacuation space of the remaining rails can be reduced. Therefore, it is effective to install the rail truck on an existing rail facility where the space for installing the evacuation device is small. Further, the side shift device of the present invention does not require high rigidity or high stop position accuracy of the track bogie, and thus can be easily configured.
