Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wear powder removing section of a trolley wire for sliding a current collector to supply power or transmit a signal.

[0002]

2. Description of the Related Art A trolley wire for sliding a current collector, particularly an insulating trolley wire, is a mode in which an insulating cover is covered on a conductor except for a surface to be slid, and a collector with an insulating cover is provided on both sides of the slidable surface. An electronic guide wall is formed.

The above-mentioned insulated trolley wire is used for power supply and / or control signal transmission of a monorail type self-propelled transport vehicle or the like. In this case, a sliding surface is laterally mounted on a side surface of a metal or aluminum rail. It is a so-called laterally laid insulation trolley wire that can be attached.

[0004] In addition, an insulating section is provided on a laying route in order to separate a power supply section and a control section. This insulation section is obtained by bridging insulation section constituent members between the ends of the divided insulation trolley wires.

[0005]

The most important problem in the above-mentioned prior art; insulated trolley wires, particularly insulated trolley wires laid sideways, is abrasion powder generated in the process of sliding current collectors. This abrasion powder is conductive, and is collected by the current collector, adheres and deposits on the insulation trolley wire laying route, particularly on the insulation section divided as a circuit division section, and improves the insulation characteristics in the insulation section. Otherwise, a short circuit may occur between the insulated trolley wires that are lowered or separated.

Conventionally, the above-mentioned measures for removing the abrasion powder have not been taken, but a cleaning brush is attached to the moving body on the power supply side, and the sliding surface of the insulating trolley wire is brushed while the moving body travels. However, the wear powder was not sufficiently removed, and it was unavoidable that the accumulation of the wear powder progressed with long-term use.

[0007] In recent years, the frequency of operation of moving bodies in self-propelled transport vehicles and the like has been increasing, and as a result, the amount of wear powder generated has increased more than before, and the wear of insulating parts such as insulating sections has been increasing. The powder tends to accumulate, and even for a short period of time, the above-mentioned cleaning of the brush attached to the moving body cannot be sufficiently performed. In addition, as a power circuit, 200 V instead of the conventional 100 V (and further, 400V), there is a tendency to use a high voltage, so that the above-mentioned short circuit and the like are easily generated. Once a short circuit or the like occurs, it is inevitable that damage will increase.

Therefore, the problems to be solved by the present invention (objects)
An object of the present invention is to provide a section for effectively removing abrasion powder on a trolley wire laying route.

[0009]

According to a first aspect of the present invention, there is provided a trolley wire having a section member bridging between ends of a trolley wire which is spaced apart from each other.
The section constituting member is provided with wear powder removing means at a position at the same level as the surface to be slid on the trolley wire, and receives the end surface of the trolley wire before and after the sliding direction of the wear powder removing means. The trolley wire is provided with a stepped portion which is recessed from the level of the wear powder removing means.

According to the above-mentioned means, the abrasion powder gathered by the current collector is accommodated in the groove having the step portion as the bottom at the end of the section constituting member, and is still removed. The wear powder that adheres to the current collector without
It will be removed by the wear powder removing means in the section constituent member. As a result, wear powder adhering to the trolley wire and the current collector is effectively removed, and the accumulation of wear powder in the insulating section provided on the installation route of the trolley wire can be prevented.

The above-mentioned section constituting member may be a section peculiar to abrasion powder removal, but may also be used as an insulating section. In this case, the section constituting member is made of an insulating material; plastic or the like. In addition,
The trolley wire may be a general bare trolley wire, but is preferably the above-mentioned insulated trolley wire. Therefore, the abrasion powder removal section of the present invention is most preferably applied to the insulation section of the insulation trolley wire.

The wear powder removing means may take various forms, but a desirable form suitable for practical use is an uneven surface arranged in the sliding direction, a brush, or an industrial pad.

[0013] A second means provided by the present invention is similar to the first means, and further comprises a through hole for air blowing which is opened in the step portion, for removing abrasion powder for a trolley wire. Section. According to the second means, it is possible to more effectively remove the wear powder that accumulates on the step by jetting air.

According to a third means provided by the present invention, in the trolley wire laid by the first means laid horizontally, a current collector guide side wall is provided above and below the wear powder removing means, and the current collector guide is provided. The lower part of the side wall is provided with a trolley wire abrasion powder removal section provided with a notch into which abrasion powder can be dropped. According to the third means, the abrasion powder deposited on the upper surface of the member which is likely to be laid in the horizontal direction can be naturally dropped from the notch in the lower portion of the side wall for the current collector guide. Powder can be removed.

Further, mounting holes 4a and 4b are formed in the bottom surfaces of the insertion grooves 2 and 2, respectively.

On the other hand, the abrasion powder removing means 3 is provided at the position where the level is the same as that of the sliding surface of the insulating trolley wire.
a and the concave portion 3b are arranged in a row, and the convex portion 3a serves as a directly slidable surface. Therefore, the shape of the current collecting surface of the slidable surface of the insulating trolley wire; It is.

The side walls 1a, 1a of the insertion grooves 2, 2 and the side walls of the abrasion powder removing means 3 are separated from each other via a slit 1c. This is because the side walls 1a, 1
When a is sandwiched between the insulating trolley wires 5a and 5b, the pin has elastic holding force, and both side walls of the wear powder removing means 3
This is because a bridge between the insulating trolley wires 5a and 5b is formed without being affected by the elastic deformation of both side walls of the insertion groove portion to form a current collector traveling guide. Since both side walls of the abrasion powder removing means 3 are higher than both side walls 1a, 1a of the insertion groove and are aligned with the side surfaces of the insulating trolley wires 5a, 5b, the same function as the insulating cover of the insulating trolley wire is achieved.

The section constituting member 1 has the mounting holes 4a, 4a with the back surface opposite to the groove side being applied to the rail.
b, the screws are fixed to the rails, and the ends of the insulating trolley wires 5a, 5b are inserted into the insertion grooves 2, 2 on both sides of the section constituting member, and the ridges 1b, 1b in the grooves are connected to the insulating trolley wires 5a, 5b. The two side grooves are fitted and locked.
When the insertion of the insulating trolley wires 5a, 5b is completed, the ends of the insulating trolley wires are brought into contact with the end surfaces of the insertion grooves 2, 2; the side surfaces connected to the steps 8a, 8b.

When the section constituting member 1 is bridged between the ends of the insulating trolley wires 5a and 5b as described above, the insulating trolley wires 5a and 5 are provided on both sides of the wear powder removing means 3.
The side surfaces of b face each other, and a deep groove having the steps 8a and 8b as the bottom is formed. This deep groove is sufficient to contain the abrasion powder.

Therefore, the abrasion powder adhering to the sliding surfaces 6, 6 of the insulating trolley wires 5a, 5b is gathered by the current collector traveling along with the moving device, and is collected by the steps 8a, 8b.
It falls into the deep groove above and accumulates. Still, the wear powder adhering to the current collector is wiped off by the alternate running of the convex portion 3a and the concave portion 3b of the wear powder removing means 3. Accordingly, a large amount of abrasion powder does not accumulate on the large number of convex portions 3a and concave portions 3b in the section constituting member 1, and the insulation performance is maintained by the creepage distance between the large number of convex portions 3a and 3b, and the insulating trolley is provided. The short circuit between the lines can be prevented, and the section constituting member 1 functions as an insulating section.

Even if the abrasion powder adheres and accumulates on the section constituting member 1, it takes a long time until a short circuit occurs, and a maintenance cycle is performed during that time, so there is no danger of causing a short circuit.
