[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an insulated trolley wire pickup guide for guiding a shoe head from one insulated trolley wire to another insulated trolley wire.

[0002]

[Prior Art]

 FIG. 4 shows a cross-sectional view of an example of the insulated trolley wire 1. The insulated trolley wire 1 has a structure in which an 8-shaped conductor 2 is covered with an insulating cover 3 and a cover opening 4 is provided at a lower portion, and a shoe head (not shown) that has entered the cover opening 4 is provided. Contacts the lower surface of the conductor 2 to collect current.

Such an insulated trolley wire 1 is used continuously as a power supply line for power of a crane or a traveling carriage, and is also switched (an insulated trolley wire whose moving body is one side) like a point of a train line. From the other to the insulated trolley wire).

FIG. 5 shows the structure of such a switching connection portion of the insulated trolley wire 1. In this case, the switching connection portion of the insulated trolley wire 1 is provided with a movable base 5 between the portions where one insulated trolley wire 1A is switched to the other curved insulated trolley wire 1B or the straight insulated trolley wire 1C. The curved insulation trolley wire 1b and the straight insulation trolley wire 1c were fixedly mounted on the upper part of the structure 5.

In such a switching connection portion of the insulated trolley wire 1, in the illustrated state, the shoe head can be guided from one insulated trolley wire 1A to the other curved insulated trolley wire 1B.

Next, when it is necessary to guide the shoe head from one insulated trolley wire 1A to the other straight insulated trolley wire 1C, the movable base 5 is moved to the left in the figure to move the straight insulated trolley wire 1c to one side. From the insulated trolley wire 1A to the other straight insulated trolley wire 1C.

In such a place where the switching connection portion of the insulated trolley wire 1 is provided, insulation is provided between the end portion of the fixed side insulated trolley wire and the end portion of the movable side insulated trolley wire, for example, as shown in FIG. Pickup guides 6 are provided at the end of the trolley wire 1A and the end of the curved insulating trolley wire 1c so that the shoe head can be easily transferred.

FIGS. 7 to 9 show the structure of a conventional pickup guide 6 of this type. The pickup guide 6 includes a tapered guide portion 6a, a linear guide portion 6b connected to the tapered guide portion 6a via an angle changing portion 6c, and a suspension provided on the upper surface of the tapered guide portion 6a via a bracket 7a. The metal fitting 8a and the hanging metal fitting 8b provided on the upper surface of the linear guide portion 6b via the bracket 7b are provided.

With the pickup guide 6 having such a structure, when the end portion of the fixed side insulated trolley wire and the end portion of the movable side insulated trolley wire are slightly displaced, the shoe head is smoothly guided. You can

[0010]

[Problems to be solved by the device]

 However, in the pickup guide 6 having such a structure, when the end portion of the fixed-side insulated trolley wire and the end portion of the movable-side insulated trolley wire are displaced to some extent to a certain degree, the tapered guide portion 6a is moved to the linear guide portion. There is a problem in that the shoe head is caught in the angle changing portion 6c where the angle changes in the portion 6b, and a great shock is given to the moving body side.

An object of the present invention is to provide an insulated trolley wire that can smoothly pass without being shocked when a shoe head passes a portion where an angle changes from a tapered guide portion to a linear guide portion. To provide a pickup guide.

[0012]

[Means for Solving the Problems]

 To explain the structure of the present invention which achieves the above-mentioned object, the present invention has a tapered guide part and a linear guide part connected to the tapered guide part. In the insulated trolley wire pickup guide that guides the shoe head to the other insulated trolley wire via the shaped guide section, the angle changes in multiple steps from the tapered guide section to the linear guide section. It is characterized in that an angle changing unit is provided.

[0013]

[Action]

 If an angle changing part that changes the angle in multiple steps is provided in the part where the angle changes from the tapered guide part to the linear guide part, the angle change angle of each angle changing part becomes loose and the angle changing part is changed. When the shoe head passes by, it can pass smoothly without being shocked.

[0014]

【Example】

 1 to 3 show an embodiment of an insulated trolley wire pickup guide 6 according to the present invention. The parts corresponding to those in FIGS. 7 to 9 described above are designated by the same reference numerals.

In the insulated trolley wire pickup guide 6 of the present embodiment, angle changing portions 6c1 and 6c2 that change the angle in two steps are provided at the portion where the angle changes from the tapered guide portion 6a to the linear guide portion 6b. Has been.

When the angle changing portions 6c1 and 6c2 that change the angle in two steps are provided in the portion where the angle changes from the tapered guide portion 6a to the linear guide portion 6b as described above, the angle changing portions 6c1 and 6c2 can change the angle. When the change angle becomes loose and the shoe head passes through the angle changing part, it can smoothly pass without being shocked.

In the above embodiment, the angle changing parts 6c1 and 6c2 that change the angle in two steps are provided, but the angle changing parts that change the angle in three or more steps may be provided.

[0018]

[Effect of the device]

 As described above, in the insulated trolley wire pickup guide according to the present invention, the angle changing portion for changing the angle in a plurality of steps is provided in the portion where the angle changes from the tapered guide portion to the linear guide portion. The angle change in the section becomes loose, and when the shoe head passes through the angle change section, it can smoothly pass without being shocked.
