JPH05270405A - Mechanism for switching running direction of vehicle in track crossing part - Google Patents

Abstract

PURPOSE:To switch and transfer a vehicle to run from one track to the other track in a part where the two tracks are crossed nearly in the orthogonal direction. CONSTITUTION:In a condition that a vehicle is positioned in a crossing part between tracks A, B, a wheel group al to a4 corresponding to the track A and a wheel group b1 to b4 corresponding to the track B are provided in the vehicle. The vehicle is constituted so as to lift at least one of the wheel group a1 to a4 and the wheel group b1 to b4 relating to a body of the vehicle by lift devices 17. The vehicle 10 is stopped in a predetermined position of the track crossing part and replaced from the one track to the other by lifting up or lowering down the one wheel group by the lift devices 17.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facility for running a truck or the like for transporting materials along a track in, for example, an assembly factory for construction materials, and more particularly to a portion where two tracks intersect in a substantially orthogonal direction. Relates to a mechanism for switching the traveling direction of a vehicle.

[0002]

2. Description of the Related Art When a track is laid so as to draw a gentle arc and there is no space to change the traveling direction of a vehicle, as disclosed in Japanese Utility Model Publication No. 1-13602 (B60B 17/00), A mechanism has been developed in which two tracks A and B are laid so as to intersect in a substantially orthogonal direction and the traveling direction of the work carriage is switched from one track to the other track.

[0003]

[Problems to be solved by the invention] Actual fairness 1-13602
In the prior art disclosed in Japanese Patent Publication No. JP-A-2003-264, a child carriage for track B is mounted on a parent carriage traveling on one track A,
The parent carriage running on the track A is positioned at the intersection with the track B, and the child carriage is moved from the parent carriage to the track B in that state. As described above, the conventional technique is configured to use substantially two vehicles, and even after the child carriage is moved to the track B, the parent carriage remains on the track A, and the child carriage alone returns to the track A. It is not possible to do so, and the parent carriage must be picked up at the crossing. As described above, since there are great restrictions on the operation of the dolly, there is a problem that the versatility is poor and the usage form is limited.

The present invention has been made in view of the above-mentioned conventional problems, and an object thereof is to move one vehicle from one track to the other track at a portion where two tracks A and B intersect in a substantially orthogonal direction. The purpose is to be able to replace and run.

[0005]

Therefore, in the present invention, the vehicle for the track B is moved to the position corresponding to the track B in the state where the vehicle travels on the track A by the wheel group a and is positioned at the track intersection. A wheel group b is provided, and at least one wheel group a or b is configured to be capable of moving up and down with respect to a vehicle body by a lifting device, and one wheel group is raised or lowered while the vehicle is positioned at the track intersection. Therefore, the vehicle is transferred from the track A to the track B.

[0006]

When the wheel group a travels on the track A, one of the wheel groups is lowered or lifted by the lifting device so that the other wheel group b does not interfere with the tracks A and B. In this state, the vehicle is positioned at the track intersection, and the lifting device is lowered or raised. Then, the wheel group b approaches the track B and comes into contact therewith, and the force of the lifting device pushes the vehicle body upward. As a result, the wheel group a is separated from the track A, the vehicle is placed on the track B by the wheel group b, and the vehicle can run along the track B.

1 and 2 show the structure of an embodiment of the present invention. Figure 1 shows two trajectories A and B intersecting in the orthogonal direction.
FIG. 10 is a plan view of the intersection of FIG. 4 and shows a vehicle positioned at the track intersection by a chain double-dashed line. The track A is composed of parallel rails A1 and A2, and the track B is composed of parallel rails B1 and B2. At the intersecting portion where the tracks A and B intersect at right angles, a rail splicing structure is provided so that the truck 10 can pass in both directions.

The bogie 10 has a group of wheels a1, a2 for the track A,
a3, a4, and a wheel group b for track B
1, b2, b3, b4 are provided. Wheels a1 and a2 are mounted on axle 11, and wheels a3 and a4 are mounted on axle 12. The distance between the axles 11 and 12 is larger than the distance between the rails B1 and B2 as shown in FIG. Similarly, wheels b1 and b2 are attached to axle 13, wheels b3 and b4 are attached to axle 1.
It is attached to 4. The distance between the axles 13 and 14 is larger than the distance between the rails A1 and A2.

Further, as shown in FIG. 2, the wheel bearings 15 of the axles 11 and 12 of the wheel groups a1 to a4 for the track A are fixed to the vehicle body of the truck 10 and the wheel groups b1 to b4 for the track B are fixed. The axle bearings 16 of the axles 13 and 14 are attached to the vehicle body of the truck 10 via a hydraulic jack 17 corresponding to the lifting device. That is, by driving the hydraulic jack 17, the wheel groups b1 to b4 for the track B can be displaced in the vertical direction with respect to the vehicle body of the carriage 10.

Although not shown, a stopper device is provided on the track A side to stop the truck 10 traveling on the track A and reaching the track intersection at the position shown in FIG. When the truck 10 is positioned at the track intersection by the stopper device, the wheel group b1 for the track B not used for traveling
1 to b4 are located right above the rails B1 and B2 of the track B as shown in FIG. At this time, the wheel groups b1 to b4 are pulled upward with respect to the truck 10 by the hydraulic jack 17, and an appropriate gap is opened between the wheel groups b1 to b4 and the rails B1 and B2. The wheel groups b1 to b4 do not hinder traveling along the track A. A stopper device for stopping the carriage 10 traveling on the track B and reaching the intersection of the tracks at the position shown in FIG. 1 is also provided.

FIG. 2 shows the details of the main part of the state where the carriage 10 travels on the track A and is positioned with respect to the track intersection. Here, as described above, the wheel group b1 for the track B1
The b4 is pulled up by the hydraulic jack 17, and the wheel groups b1 to b4 are arranged directly above the rails B1 and B2 with a predetermined interval. In this state, the hydraulic jack 17 is driven to displace the wheel groups b1 to b4 downward. Then, the wheel groups b1 to b4 approach the rails B1 and B2 and finally come into contact with each other, and the wheel groups b1 to b4 further push the rails B1 and B2 to displace the trolley 10 upward by a reaction force. a1 to a4 separate from the rails A1 and A2. That is, the truck 10 is placed on the rails B1 and B2 of the track B by the wheel groups b1 to b4. Therefore, the truck 10 can be driven on the track B by the wheel groups b1 to b4. It should be noted that in order to transfer the carriage on the track B to the track A for traveling, the operation is completely opposite to the above procedure.

[0012]

As described in detail above, in the mechanism of the present invention, both the wheel group for track A and the wheel group for track B are provided on the same bogie so that both tracks A and B are almost the same. The vehicle can be transferred from one track to the other track by raising or lowering one of the wheel groups by the lifting device at the portion intersecting in the orthogonal direction. Therefore, the traveling direction of the same vehicle can be switched at the track intersection. For this reason, tracks can be laid vertically and horizontally in a limited space such as an assembly factory for construction materials, and trucks for material transportation can be arbitrarily switched and run on each track.
