Description

[Detailed Description of the Invention] As automatic control groups such as production lines and transfer lines in production plants become more complex and sophisticated, the number of electric wires increases for power supply and control transmission to controlled moving devices, and In addition to increasing the number of trolley feed lines, there is also a need for corresponding changes in the current collector brushes.

For this reason, the conventional method of installing feeder lines in parallel and spaced lines on a horizontal plane has been transformed into a multi-wire vertical trolleybus duct in which they are installed on a vertical surface.

The necessity of changing from a horizontal bus duct to a vertical bus duct is due to the various obstacles that arise when the number of trolley wires increases, resulting in a significant difference in the peripheral speed between the inner and outer wires at curved sections of travel, and further increases the occupied surface area. It also happens to the inconvenience of

In this way, multi-wire vertical trolleybus ducts meet the demands of the times, and in these as well, the width of the sliding current collector in the running direction is increasing in order to collect electricity better. Accordingly, there is a problem in that it is difficult to pass through curved parts, resulting in unstable current collection.

In view of this, the present applicant previously developed a ``Trolley for Trolley Bus Duct'' by dividing a single trolley car into a part where the wheels are attached and a part where the brushes are attached, and connecting them by hinges. I suggested something.

Such a trolley, ie, a sliding current collector, is extremely effective because the area on which the current collecting brush is mounted can be reduced to the bare minimum width.

In the multi-wire vertical trolley current collection system, the radius of curvature of each conductor of the trolley wire is the same when passing through a curve, so current collection at the curve is stable. According to the above, when traveling on a route with many curves and a small radius of curvature, the current collecting brush part and the wheel part are hinged together, which increases the flexibility of free swing movement. Therefore, it realizes even more stable current collection.

The present invention is based on the confirmation of this reality, predicts the situation where current collecting capacity is insufficient when the current collecting device of a multi-wire vertical trolleybus duct is turned on, and solves the problem.

In other words, when the current collection capacity of one line and one brush is insufficient, it is possible to collect current in the same phase, and this is achieved by a system in which two or more trolleys are brought together, and the connection of each trolley is sufficient. Its flexibility allows it to handle the harsh conditions of curved areas, ensure stable current collection, and overcome uneven contact without intermittent current collection.

The present invention will be specifically described in detail below with reference to figures showing examples.

First of all, Figure 1 is a side view of the current collector of a multi-wire vertical trolleybus duct, Figure 2 is a front view of the collector, and Figure 3 is a bottom view of Figure 1, which are based on the book mentioned above. This is an example of the applicant's previous proposal. In these figures, 1 is a bus duct mounting frame, 2 is a bus duct bent in a U-shape, and 3 is a bus duct mounting frame.
An insulating support on the back side of the insulating support, 4 several conductors serving as a trolley wire, 5 a sliding brush for current collection, 6 a brush holder, 7
is the brush unit base and W, , W2 are wheels.

W, , W2 are attached to the wheel unit base 9 as upper and lower wheels, and the unit bases 7 and 9 are connected to hinge joints H, ,
The buttons are connected to each other in an articulated manner by pressing the button H2.

8 is a trolley frame material, 10 is a bus duct protection cover, 11
is a connection box, and 12 is a lead wire.

A towing edge (not shown) is separately attached to the box 11.

As can be seen from Fig. 3, in this configuration, rail R2 (Rt
(7) At the curved point, the wheel unit base 9 moves with the brush units 5 to 7 while tilting its head as the wheel W2 moves.

FIG. 4 shows a mode in which two of the above-mentioned current collectors are connected as one unit for index towing (C1e, C2p, and C3 tow strings in the figure), which corresponds to the original idea of the present invention.

By the way, although this type achieves its purpose, from a practical point of view, the overall dimensions of the trolley become longer, the number of wheels increases, the running noise becomes louder, the stability is also lowered, and the price becomes higher. There are various drawbacks such as:

FIG. 5 and the following correspond to specific examples based on the gist of the present invention.

Here, the symbols used in FIGS. 1 to 4 are used for the corresponding parts.

The hinge pivot parts H1$- and H2 align the lug P1 protruding from the board 9 and the lug P2 protruding from the board 7, and align the axis S with the seventh
They are fitted as shown in the figure, and the axis S is aligned with the center line of the wheels W□, W2.

In particular, as can be seen from Figures 5 and 6, the plush knit base plates I, I[, and m are wheel unit bases ■'.

It is located between n', m', and rv' and is articulated and towed in the form of a trailing body.

When approaching a curve in this state, the leading wheel unit base ■ tilts its head according to the curve, then the brush unit base I adapts to it, and then n'-n-m'-
It has a shape that corresponds to m, and can easily pass through curves with a small radius of curvature and shoes.

At this time, if the position of mutual joint connection is shifted to the left or right from the center line of wheels w1 and W2, as shown in Fig. 2, for example, one side of the brush unit can be pried up using a lever action corresponding to the shift size. action occurs.

The brush is subjected to a spring extrusion action within the brush holder, but the above-mentioned stiffening action not only makes the contact pressure of the brush unbalanced, but in extreme cases, there is a risk that the brush and the wiring may come into contact with each other and cut off the current flow. It was experienced that this caused problems in power supply and control, and as a result, as shown in Figures 5 and 7.
It has been found that it is ideal to do as shown in the figure.

This is why one of the objects of the present invention is to achieve the structure as shown in FIGS. 5 and 7, and to show it closely.

It can be seen that all other objects of the present invention can be achieved if the number of units to be connected is taken into consideration according to the degree of curve of the towing course and the current flow rate to be handled, and the size of the unit base is selected and assembled. .

In the above description, wheel units are used as joints in the construction of the train, but the present invention is not limited to this, and as shown in FIG. 9 and FIG. Wheels W1 and W2 are provided to make it a self-propelled type, and the prongs P2 are aligned with each other and pivoted to pivot H,, H2.
It is also possible to adopt a joint connection style, which can be selected and adopted depending on the towing course.

In the case of FIG. 10, the wheels W1 and W2 are provided diagonally above and below the base 7, so that they are equally effective.
