Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an improvement of a trolley wire support device.

<Prior art and problems> As a train track system, guide rails 1', 1' are extended on both sides of the track base as shown in Figure 3A,
This is supported by rail support legs 2', . . . at predetermined intervals as shown in Fig. 3B, and trolley wire support legs 3',
An adjustment plate 42' with a trolley wire support insulator attached is arranged on a fixing plate 41' attached to the upper end of each trolley wire support leg, and by fine adjustment of this adjustment plate 42', There is a known method that ensures proper contact between the trolley wire 5' and the train side current collector 6' (in Fig. 3A,
7', 7' are train guide wheels, 8', 8' are rubber wheels).

However, the adjustment mechanism of the conventional adjustment plate is complicated, and the adjustment work is not easy.

<Objective of the invention> An object of the invention is to provide a trolley wire support device in which the adjustment mechanism of the adjustment plate is simple and the adjustment work is easy.

<Structure of the invention> The trolley wire support device according to the invention includes a rack attached to the back side of a fixing plate for supporting the trolley wire,
A structure characterized in that a slidable adjustment plate is disposed on the surface of the fixed plate, a pinion that engages with the rack is pivotally supported on the adjustment plate, and a trolley wire is supported on the adjustment plate via an insulator. It is.

<Explanation of Examples> The present invention will be explained below with reference to the drawings.

FIG. 1A is a side view showing a trolley wire support device according to the present invention, and FIGS. 1B and 1C are FIG. 1A.
FIG. 1B is a front view (a part of the insulator in this figure is omitted in FIG. 1A) and a back view of the S portion in FIG.

In FIGS. 1A to 1C, 1 is a guide rail. 2 is a leg for supporting the trolley wire attached to the guide rail 1, and a fixing plate 3 is provided at the upper end via a spacer 21 (these 2,
21 and 3 are welded together in the factory).
Reference numeral 4 designates an adjustment plate, and trolley wire supporting insulators 51, . . . are mounted on the plate 4, and rigid trolley wires 52, . 61 is a bolt insertion hole provided above the adjustment plate 4, 611 is a bolt, and 612 is a nut. The bolt insertion hole 61 is in the shape of a vertically elongated hole, and its width is equal to or slightly larger than the diameter of the bolt 611. It has been done. Therefore, when the nut 612 is loosened, the adjustment plate 4 can be moved up and down.

71, 71 are bolt insertion holes provided on the left and right sides of the lower position of the adjustment plate 4, and these bolt insertion holes 71, 71 are provided with position adjustment bolts 711, 71.
1 is inserted through each. 712,712 is Natsu. 713, 713 are the bolt insertion holes 71, 71 and position adjustment bolts 711, 711
These collars 713, 713 have elongated holes 713a, 713 for inserting and supporting position adjustment bolts 711, 711.
13a and hexagonal flange portions 713b, 713
b are formed respectively. 8 is a rack attached to the back side of the fixed plate, and as shown in FIG. 2, it has an arm 82, a groove 83 that engages with the pinion,...
The pinion insertion hole 84 has a vertically elongated shape so that a pinion shaft 91 (described later) can slide in the vertical direction, and the width of the hole is equal to the diameter of the pinion shaft 91. Or make it a little bigger. Reference numeral 85 indicates a bolt insertion hole provided in the arm 82, and the hole diameter is the same as that of the bolt 6.
It is set approximately equal to 11. Thus, the rack 8 is supported by bolts 611. A pinion 9 is meshed with the rack 8, and has a shaft 91 supported by the adjustment plate 4, with an upper end 910 of the shaft protruding from the adjustment plate 4. This protruding end 91
0 has a square shape so that it can be rotated with a spanner.

Thus, by making the adjustment plate 4 vertically movable (by loosening the nuts 612, 712, and 712), and rotating the pinion 9 with a spanner or the like in this state, the vertical position of the adjustment plate 4 can be finely adjusted. , trolley wire 52, . . . can be accurately positioned.

<Effects of the Invention> The trolley wire support device according to the present invention has the above-described configuration and is of the rack-and-pinion type, so that fine adjustment is easy. Furthermore, the mechanism is simple, as the pinion is pivotally supported on the adjustment plate and the rack is fixed on the fixing plate.
