Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parent-child traveling vehicle used in, for example, a transportation line for transporting heavy objects in a casting facility.

[0002]

2. Description of the Related Art Conventionally, as a parent-child traveling vehicle of this type, a parent vehicle is provided so as to be able to travel along a traveling rail,
It is known that a traversing rail is provided on the body of the parent trolley, and a child trolley is provided along the traversing rail so as to be able to travel freely. Then, the parent bogie travels along the traveling rail, and at the intersection of the traveling rail and the traversing rail, the child bogie travels along the traversing rail to transport the heavy object on the child bogie to the destination. It has become.

[0003]

However, in the above-described conventional parent-child traveling cart, since the traversing rail for the child cart is provided on the body of the parent cart, the weight to be conveyed is considered due to the strength. It is necessary to increase the strength of the body of the parent bogie that supports the weight of the object and the weight of the child bogie and the traversing rail for the child bogie, and the traveling bogie itself becomes inevitably high, resulting in poor stability during traveling. In addition, there is a problem that the equipment cost is increased due to the necessity of increasing the height of the peripheral equipment in accordance with the height of the traveling vehicle.

[0004] The present invention has been made in view of the above circumstances, and an object thereof is to reduce the height of a traveling vehicle and to greatly improve the traveling stability of the traveling vehicle. In addition, another object of the present invention is to provide a parent-child traveling vehicle in which the height of peripheral devices can be reduced in accordance with the traveling vehicle, and equipment costs can be reduced.

[0005]

According to the present invention, there is provided a main carriage movably provided along a traveling rail, and a transverse rail provided on a rocker frame for supporting the traveling wheels of the main trolley. And a child carriage movably provided along the traversing rail. According to the first aspect of the present invention, by providing the traversing rail for the child trolley on the rocker frame supporting the traveling wheel of the parent trolley, the traversing rail can be set low, and therefore, the traveling trolley can be lowered. And peripheral equipment can be lowered accordingly. According to a second aspect of the present invention, the table is provided on the sub trolley so as to be able to move up and down. According to the second aspect of the present invention, the heavy object on the table is delivered to the receiving stand or the rotating roller on the ground side by lifting and lowering the table provided on the subsidiary carriage.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a front view of a parent-child traveling vehicle,
2 is a plan view of FIG. 1, and FIG. 3 is a side view of FIG. In the figure, reference numeral 1 denotes a pair of traveling rails laid in parallel with each other, and a main carriage 2 is provided on these traveling rails 1 so as to be able to travel. In the main carriage 2, a pair of rocker frames 3 are arranged at a predetermined distance from each other, a pair of traveling wheels 4 are provided at both ends of the rocker frames 3 so as to be rotatable, and the traveling of one rocker frame 3 is performed. The traveling motors 5 for rotating the traveling wheels 4 are respectively connected to the wheels 4. And
A traverse rail 6 is provided on each of the rocker frames 3, and a traveling wheel 8 of a child carriage 7 is provided on the traverse rail 6 so as to be able to travel. These traveling wheels 8 are rotatably mounted on a vehicle body 9 of the child carriage 7 and are made to travel by a traversing motor 10 provided on the vehicle body 9. The vehicle body 9
A table 11 is provided on the upper side so as to be able to move up and down. The table 11 can be moved up and down by an elevating mechanism 12 composed of a motor-driven screw jack installed on the vehicle body 9.

Further, at a predetermined position of the traveling rail 1, a traversing rail 13 connected to the traversing rail 6 is laid on the ground side, and separated from the intersection of the two rails 1 and 13 by a predetermined distance. On the side of the traversing rail 13, a rotating roller 14 and a receiving table 15 are installed, respectively. The rotating roller 14 is driven to rotate by a sprocket and a chain. An insulation trolley 16 for supplying power to the parent carriage 2 (the traveling motor 5) is laid along the traveling rail 1. A power supply device 17 that feeds out or winds a cable is installed on the vehicle body 9 of the child bogie 7. When the child bogie 7 is separated from the parent bogie 2 along the traversing rail 13, A cable is fed out from the power supply device 17, and power is supplied from the insulating trolley 16 to the traversing motor 10 and the elevating mechanism 12 via the power supply device 17.

In the parent-child traveling vehicle constructed as described above, when a heavy object (transported object) 18 is placed on the table 11 of the child vehicle 7, the electric power supplied from the insulating trolley 16 is used. By driving the traveling motor 5, the parent carriage 2 travels along the traveling rail 1 together with the child carriage 7. When the parent bogie 2 reaches the intersection of the two rails 1 and 13, the main bogie 2 is stopped, and the traversing motor 10 is driven to drive the traversing rails 6 and 13.
The child carriage 7 is driven along. In this case, the lifting mechanism 1
The table 11 is raised by a predetermined height together with the conveyed article 18 by means of 2. Further, the cable of the power supply device 17 is fed out with the travel of the child trolley 7, so that the power supply from the main trolley 2 is reliably transmitted to the child trolley 7 via the power supply device 17, and the traversing motor There is no hindrance to the driving of the lifting mechanism 10 and the lifting mechanism 12.

Next, the child carriage 7 reaches the position of the rotating roller 14 or the receiving table 15, and the conveyed article 18 on the table 11 of the child carriage 7 is positioned above the rotating roller 14 or the receiving table 15. Then, after stopping the sub trolley 7, the table 11 is lowered by the elevating mechanism 12, and the conveyed article 18 on the table 11 is transferred to the rotating roller 14 or the receiving table 15. In this way, the conveyed article 18 conveyed by the parent-child traveling cart
Can be smoothly and reliably transferred to the rotating roller 14 or the receiving table 15. In the case where the conveyed article 18 on the rotating roller 14 or the receiving table 15 is transferred to the sub-car 7 side, the sub-car 7 is run by the traversing motor 10 while the table 11 is lowered by the elevating mechanism 12. The table 18 is lifted by the elevating mechanism 12 so that the conveyed material 18 on the rotating roller 14 or the receiving table 15 is transferred to the table 11 by the lifting mechanism 12. do it. Further, it is needless to say that the present embodiment can be applied not only to a transfer line of a casting facility, but also to a transfer line of various heavy objects such as a transfer of an iron making coil.

[0010]

As described above, according to the first aspect of the present invention,
According to the above, by providing the traversing rail for the child trolley on the rocker frame that supports the traveling wheels of the parent trolley, the traversing rail can be set low, and therefore the traveling trolley can be lowered, Can be lowered accordingly. As a result, the traveling stability of the traveling vehicle can be reliably improved, and the height of the peripheral devices can be reduced according to the traveling vehicle, so that the equipment cost can be significantly reduced. According to the second aspect of the present invention, by moving up and down the table provided on the sub trolley, it is possible to easily transfer the conveyed goods on the table to the receiving stand or the rotating roller on the ground side. Therefore, the conveyed object can be smoothly and reliably conveyed, and there is no hindrance to the operation of conveying the heavy object.
