Abstract

(57) [Abstract] [Purpose] To provide a current collector for an insulating trolley for horizontal use in which the following performance for the trolley wire is enhanced and the trouble of disconnection is reduced. [Structure] Horizontal link 1 having current collecting brush 3 at its tip
Is attached to the mounting bracket 6 via the vertical shaft 4 and the horizontal shaft 5. Further, the horizontal link 1 to which the brush pressing force against the trolley wire is applied by the spring 8 is received from below by the plate spring 9 and is maintained in the horizontal position. Unlike conventional current collectors that balance the weight with a counter weight, those without a counter weight are weighed and follow the trolley wire well by becoming lighter.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile power source (insulating trolley) for cranes, hoists, automated warehouses, multilevel parking lots, etc.
The present invention relates to a current collector.

[0002]

2. Description of the Related Art Conventionally, when a current collector for an insulating trolley is mounted sideways, a counterweight 2 is conventionally mounted to keep a horizontal link 1 in a horizontal position, as shown in FIG. Reference numeral 3 is a brush for collecting current that contacts the insulating trolley A, and is attached to one end of the horizontal link. The other end of the horizontal link 1 is attached to the horizontal shaft 5 via the vertical shaft 4,
The horizontal shaft 5 is rotatably mounted on a mounting bracket 6. An adjusting bolt 7 is attached to the horizontal shaft 5, and a counterweight 2 attached to the bolt cancels a rotational moment due to the own weight of the horizontal link 1 to keep the link horizontal. Reference numeral 8 in the drawing denotes a spring that attracts the horizontal link 1 to the insulating trolley side and presses the brush 3 against the trolley wire.

[0003]

A conventional current collector that balances the weight of the counter weight and the weight of the horizontal link to keep the horizontal link in the horizontal position has a heavy counter weight, and therefore the traveling speed of the moving body during power feeding. When the speed of the trolley wire becomes faster, the follow-up performance to the sway of the trolley wire deteriorates, and sometimes the wire departs.

An object of the present invention is to eliminate such a problem.

[0005]

In order to solve the above problems, in the present invention, a horizontal link having a current collecting brush at its tip can be horizontally oscillated and vertically rotated via a vertical axis and a horizontal axis. In a current collector of an insulating trolley that supports and further applies a spring force for laterally pressing the brush against a trolley wire to the link, a structure for applying a spring force to the link to cancel a downward rotational moment due to its own weight To adopt.

[0006]

[Operation] The weight of the spring is much smaller than that of the counterweight. In the present invention, the spring is used to maintain the balance of the horizontal link, so that the weight of the device is reduced and the follow-up performance during high-speed sliding is improved.

[0007]

1A and 1B show a first embodiment of the present invention. As shown in the figure, the horizontal link 1 is attached to a mounting member 6 via a vertical shaft 4 and a horizontal shaft 5 so as to be horizontally swingable and vertically rotatable. Brush 3 is attached to this horizontal link 1.
Is attached, and a force is applied by the spring 8 in the direction of pressing the brush 3 against the insulated trolley wire. Further, a leaf spring 9 characterizing the present invention is attached to the lower portion of the mounting member 6 by screwing, and the leaf spring 9 pushes up the horizontal link 1 from the lower side to a position where the horizontal link 1 is kept in a horizontal position. In the embodiment, the mounting hole 10 of the leaf spring 9 is a long hole, and the supporting point of the horizontal link by the leaf spring 9 is changed within the range of accommodation by the long hole to adjust the pushing force of the leaf spring. There is.

FIG. 2 shows a second embodiment. This current collector uses a coil spring 11 in place of the leaf spring 9 described above, and applies a rotational force to the horizontal shaft 5 with the coil spring 11 having one end fixed to the fitting 6 and the other end locked to the horizontal shaft 5. Is balanced with the rotational moment of the horizontal link due to its own weight, and the horizontal link 1 is kept in a horizontal position. This coil spring 11 is also provided with some holes for locking the ends, and the pushing force of the horizontal link 1 can be changed by changing the locking position of the ends so that the tightening state on the horizontal shaft 5 changes. .

[0009]

As described above, in the current collector of the present invention, the horizontal link is prevented from sagging due to its own weight by the force of the leaf spring or the coil spring, so that the horizontal link becomes light and easy to move. As a result, the follow-up performance to the trolley wire is improved, and the disconnection trouble at the time of speed increase is reduced.
