DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to the accompanying drawings to provide an understanding of the present invention. Here, FIG. 1 is a schematic configuration diagram of a trolley-type power supply device according to an embodiment of the present invention, and FIG. 2 is a perspective view of a main part of the trolley-type power supply device. As shown in FIG. 1, a trolley type power supply device 1 according to one embodiment of the present invention
Numeral 0 denotes power supply to the transport trolley 11 by the power supply trolley 12 laid along the traveling direction of the transport trolley 11 from which the load (not shown) is unloaded and the current collecting member 13 provided on the transport trolley 11. It is a device for performing. Hereinafter, these will be described in detail. As shown in FIGS. 1 and 2, in the trolley-type power supply device 10, the current collecting member 13 includes a V-shaped current collecting arm 14. The lower end of the current collecting arm 14 is pivotally attached to the upper surface of the moving body 16.

As shown in FIG. 1 and FIG.
Has a rectangular mounting plate 17 on which the collecting arm 14 is mounted on the upper surface, and two rail holding members 18 and 19 are provided at both ends of the lower surface of the mounting plate 17 in the running direction. . The rail holding members 18 and 19 provided on the lower surface of the moving body 16 are mounted inside the upper ends of the supporting members 21 and 22 erected at both ends in the traveling direction of the carrier 11 on the carrier body 20. The guide rail 23 can be slid in the longitudinal direction while holding the head 24 of the guide rail 23. The rail holding members 18 and 19 and the guide rail 23 constitute moving body guide means for movably supporting the moving body 16 along the power supply trolley 12.

As shown in FIG. 1, both ends of a moving body 16 that slides in the longitudinal direction of a guide rail 23 contact the upper ends of the supporting members 21 and 22 to stop the moving body 16 at both ends. Stoppers 25 and 26 are provided to face each other. At one end (right side in FIG. 1) of the moving body 16, an electric cable for supplying electricity collected from the power supply trolley 12 via the current collecting member 13 to each electric device arranged on the transporting car main body 20 is provided. Guided cable carrier 2
The upper side of 7 is attached. As shown in the figure, the cable carrier 27 is arranged in a U-shape in the horizontal direction, and the lower side thereof is arranged below the guide rail 23,
22 is fixed to an intermediate portion of a rod-shaped cable carrier holding member 28 having both ends fixed to the intermediate portion.

Accordingly, when the traveling vehicle (not shown) is driven by the electricity collected from the power supply trolley 12 to travel the carriage 11 as shown in FIG. Is located at the position a, while the left end of the moving body 16 contacts the moving body stopper 25. At this time, the center of the current collecting member 13 is located at the position a1.
Becomes Conversely, when the transport vehicle 11 travels to the left, the right end 29 of the transport vehicle body 20 is at the position b in the travel limit, and the right end of the movable body 16 abuts the movable body stopper 26. Is the position b1. As shown in FIG. 1, the moving distance A of the current collecting member 13 between the moving body stoppers 25 and 26 is determined by a position a2 where the right end of the moving body 16 abuts the moving body stopper 26, and a moving body 1
6 is the distance from the position b2 where the left end abuts on the moving body stopper 25.

Therefore, as is apparent from FIG. 1, the moving range of the current collecting member 13 (the distance from the position a1 to the position b1) is (LA) with respect to the traveling range L of the carrier 11. Here, as in the conventional example, assuming that the distance from both travel limit positions (positions a1 and b1) of the moving body 16 of the power supply trolley 12 to both end surfaces of the power supply trolley 12 is (α / 2), respectively. Is (LA + α). As a result, the length of the power supply trolley 12 can be reduced by the distance A as compared with the conventional power supply trolley 72 (see FIG. 3). Therefore, at one end or both ends of the power supply trolley 12 shortened by the distance A, the load can be unloaded onto the transport trolley main body 20 by the overhead crane or the like, or the load on the transport trolley main body 20 can be lifted. Or you can.

Next, the operation of the trolley type power supply device 10 according to one embodiment of the present invention will be described with reference to FIG. (1) When the transport trolley 11 travels, for example, near the right travel limit with respect to the power supply trolley 12 laid in a length shorter than the travel range L of the transport trolley 11 (substantially, LA), First, the traveling speed of the carrier 11 is reduced. (2) In a state where the left end of the moving body 16 to which the current collecting arm 14 of the current collecting member 13 is attached comes into contact with the moving body stopper 25 provided on the left side of the carriage 20, and the moving body 16 is stopped at that position. The carriage body 20 travels a predetermined distance further rightward and stops at the travel limit.

(3) At this time, the moving body 16 to which the current collecting member 13 is attached slides along the guide rail 23 attached to the carrier 20 while the cable carrier 27 moves. It is possible to travel to the travel limit while maintaining the power supply state. (4) Conversely, even if the transport vehicle 11 travels in the left travel limit direction, the same operation as described above is performed. Thereby, the transport vehicle 1
Power supply trolley 1 having a length substantially shorter than the travel range L
2 enables power to be supplied to the transport trolley 11, and as a result, it becomes possible to carry the cargo near the end of the transport trolley 11 without being disturbed by the power supply trolley 12.

In the above-described embodiment, the electric cable between the moving body 16 and the cable carrier holding member 28 is guided by the cable carrier 27. However, the cable carrier 27 can be omitted if necessary. Although the current collecting arm 14 of the current collecting member 13 is V-shaped and the number of the current collecting shoes 15 is two, the present invention is not limited to this, and the current collecting arm may be a bar and the current collecting shoe may be one. When there is one current collecting shoe, the length of the power supply trolley is (LA). The moving body guide means includes a rail holding member 18 provided on the moving body 16,
19 and guide rail 2 attached to carrier body 20
3 is provided, but the invention is not limited to this, and other structures may be used as long as the movable body 16 can be guided along the power supply trolley 12. Although the number of the power supply trolleys 12 is one, it is not limited to this, and two or more power supply trolleys may be used. The mounting position of the power supply trolley 12 is located above the transporting trolley 11, but may be located on the side of the transporting trolley 11 depending on the situation.

[0014]

According to the trolley type power supply device according to the first and second aspects, the moving body having the current collecting member can move between the two ends of the movement, and as a result, the length of the power supply trolley can be moved. Since the load can be shortened by the moving distance of the body, the power supply trolley does not hinder the cargo handling when the cargo on the transport trolley is handled by an overhead crane or the like. In particular, in the trolley-type power supply device according to the second aspect, since the cable bear is provided, the electric wiring work of the carrier can be simplified.
