Abstract

PURPOSE:To facilitate the position adjusting operation, in a system where an adjusting plate for supporting the trolley wire is arranged adjustably of inclination on a fixed supporting plate, by providing a position adjusting collar on the adjusting plate. CONSTITUTION:The adjusting plate 2 for supporting the trolley wire is arranged on a fixed plate 1 planted with a shaft 11 while secured to the upper end of the trolley wire supporting foot such that the shaft 11 is inserted into a triangular hole 32 in a collar 3 mounted rotatably in a round hole 21 of said plate 2. The adjusting plate 2 is supported on the fixed plate 1 while rotatably around the point A. In order to adjust the rotary angle of the adjusting plate 2, the collar 3 is rotated to contact the hexagonal hole 32 against the shaft 11. Assuming F is the force functioning onto the adjusting plate 2, L is the distance from the rotary fulcrum A to the shaft 11 and (m) is the rotary moment of spanner, it is constructed to enable application of such force as F=m/L onto the adjusting plate 2.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an improvement in a method for adjusting the position of a trolley wire support plate.

<Prior art and problems> As a train track system, as shown in Figure 4A, guide rails l' and l'' are extended on both sides of the track base, and these are
As shown in Figure B, rail support legs 2' are provided at predetermined intervals.
Trolley wire support legs 3' are erected on this guide rail unit' at predetermined intervals, and trolley wire support insulators are attached to fixed plates 31' attached to the upper ends of each trolley wire support legs. There is a known system in which an adjustment plate 32' is installed, and a proper contact state between the trolley wire 4' and the train side current collector 5' is ensured by fine adjustment of the inclination of the adjustment plate (No. 4). In Figure A, 61, 6/ are the guide wheels of the train; 7', 71 are the rubber wheels).

However, with the conventional adjustment plate adjustment method, it is particularly difficult to finely adjust the inclination, and the work is also complicated.

<Object of the Invention> An object of the present invention is to provide a method by which the inclination of the adjustment plate can be easily finely adjusted.

<Structure of the Invention> The method for adjusting the position of a trolley wire support plate according to the present invention includes disposing an adjustment plate capable of supporting a trolley wire on a fixed plate, and rotating the adjustment plate by applying a moment to the adjustment plate. In the method for adjusting the inclination of the adjustment plate, a round hole is provided in the adjustment plate,
The fixed plate has a shaft protruding through the round hole, a collar having a hole through which the shaft is inserted is rotatably mounted on the round hole, and the shaft is eccentric to the round hole. This method is characterized in that the collar is rotated, and this rotation causes a hole in the collar to come into contact with the shaft, thereby applying a rotational moment to the adjustment plate.

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

In FIG. 1A, 1 is a fixed plate with a shaft 11 projecting therefrom. This fixing plate 1 is fixed to the upper end of the trolley wire support leg as described above, but its illustration is omitted. 2 is an adjustment plate that supports the trolley wire;
A round hole 21 is provided, and a circular collar 3 having a collar 31 is rotatably mounted in the round hole 21. This collar 3 is provided with a non-circular hole 32, for example, a triangular hole, and 7 langes 3 of the collar are provided.
1 is hexagonal so that a spanner can be fitted into it.

FIG. 1B shows a front view of the adjustment plate 2 arranged on the fixed plate 1, and FIG. 1C shows a sectional view taken along the line C--C in FIG. 1B.

1B and 1C, the shaft 11 of the fixing plate 1 exists in the triangular hole 32 of the collar 3 attached to the round hole 21 of the adjusting plate 2, and the adjusting plate 2 points to the fixing plate 1. It is rotatably supported at A. The shaft 11 is eccentric with respect to the round hole 21 described above.

In order to adjust the rotation angle (tilt angle) of the adjustment plate according to the present invention, as shown in FIG. is drawn in contact with the axis 11 of the fixed plate l.

After this contact, the rotational moment of the spanner can be transmitted to the adjustment plate. In other words, the force acting on the adjustment plate 2 is F1.If the distance from the rotation point A to the shaft 11 is L1 and the rotational moment of the spanner is m, then a force of F = m/L can be applied to the adjustment plate 2, and the adjustment The tilt of the plate can be adjusted.

Figure 2A is a side view of a trolley wire support device adapted to adjust the position of the trolley wire according to the present invention, and Figures 2B and 2C are front views of the S section in Figure 2A (in this figure). A part of the insulator is omitted in FIG. 2A) and a back view.

In FIGS. 2A to 2C, 4 is a guide rail. 5 is a leg for supporting the trolley wire attached to the guide rail 4, and a fixing plate l is attached to the upper end via a spacer 51.
(These 1.51 and 5 are welded together in the factory.) 2 is an adjustment plate, and a trolley wire supporting insulator 61.2 is mounted on the adjustment plate. ..., and these insulators form a rigid trolley wire 62. I support... 71 is a bolt insertion hole provided in the adjustment plate 2;
Reference numeral 72 indicates a bolt, and reference numeral 73 indicates a nut, and the bolt insertion hole 71 is shaped like a vertically elongated hole, and its width is equal to or slightly larger than the diameter of the bolt 72. Therefore, when the nut 3 is loosened, the adjustment plate 2 can be moved up and down. 8 is a rack attached to the back side of the fixed plate 1;
As shown in FIG. 3, the arm 82 is provided with a groove 83 that fits into the pinion, and a pinion insertion hole 84.

Reference numeral 85 denotes a bolt insertion hole provided in the arm 82, and the diameter of the hole 85 is approximately equal to the diameter of the bolt 72. Thus, the rack 8 is rotatably supported by the bolts 72. Reference numeral 9 denotes a binion, which is engaged with the rack 8 and is pivotally supported by the entire binion shaft adjustment plate 2, with the upper end 910 of the shaft protruding from the adjustment plate 2. Projecting end 91 of C
0 has a square shape so that it can be rotated by Sunokusu.

Both the pinion shaft insertion hole 100 of the fixing plate 1 and the pinion shaft insertion hole 84 of the rack 8 (see FIG. 2A) are made sufficiently larger than the diameter of the pinion shaft 91, so that the pinion shaft cannot be inserted into these holes. It is movable.
