Description

[Detailed Description of the Invention] The present invention relates to an improvement of a trolley line for feeding power to mobile equipment.

Generally, when installing a contact line for power supply to mobile equipment, in order to absorb the deflection of the installed contact wire caused by temperature changes, the middle of the installed contact wire 11 is suspended and supported by a slide banger 12 at both ends. is tensioned and installed using a spring 13 with a strong spring force, but this construction method requires long contact wires in long areas of the laid track, which causes expansion and contraction of the CI and IJ wires due to temperature differences. This makes it extremely difficult to provide elastic support for the contact wire that can absorb the difference and maintain the specified tensile force.
In addition, in order to reduce the deflection of the laid contact wire, the pitch width of the slide banger that suspends the contact wire must be divided into smaller parts, which poses problems such as the work of installing the banger on a building is troublesome and takes a long time. .

The present invention has been developed in view of the above points, and an embodiment of the present invention will be described below with reference to the drawings. In Figs. 3 is a slide banger that suspends the CIIJ wire in a slidable manner, and 3 is a spring tensioned at the end of the contact wires 1 and 1 at each connection point or any connection point. It is towed and absorbs the thermal expansion and contraction of Toro IJ wire.

4 is a flexible conductor that electrically connects the connecting contact wires 1, 1; 5 is a stopper for holding down the contact wire 1 when the spring 3 stretched between the connecting contact wires breaks; As shown in FIG. 4, the contact wire may be stretched between telescopic hinge rods 4a, which are fixedly attached to the end of the contact wire as a stopper for the connecting contact wire.

Reference numeral 6 denotes a guide pin that mechanically connects the contact wires 1.1 to each other so that the contact wires 1.1 do not shift in position at their connecting portions.

According to the present invention, as described above, the contact wires 1 of a fixed length that are slidably suspended via the slide banger 2 are successively separated and connected, and the adjacent contact wires of the fixed length are connected to each other by the spring 3 at the connecting portion. Since the trolley wire 1 is towed by the wire, there is no risk that the laying contact wire 1 will bend due to thermal expansion and contraction, and since the banger pitch can be lengthened by using a short length of the contact wire, it will be easier to carry out the laying work and when the contact wire is partially damaged. It has the advantage of being easy to replace and repair.
