Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a mounting structure for an overhead contact line support device for installing a power supply overhead contact line such as a rigid contact wire laterally along a track. Rigid contact wires as described above are used, for example, in new urban transportation systems such as tire-powered trains.

(Prior art) This type of support device is attached to the mounting surface using a plurality of anchor bolts and nuts protruding from the parapet wall surface or the mounting surface of the mounting support, or fasteners such as stud bolts to the mounting surface. .
However, because the anchor bolts are planted in a concrete parapet, the positions of the anchor bolts or the distances between the anchor bolts are often incorrect, and the mounting posts are also placed incorrectly. Therefore, at the installation site,
In many cases, it was difficult to accurately attach the support device to the mounting surface.

Furthermore, although the mounting surface is formed to be perpendicular to the orbital plane, there is a tilt error of, for example, within ±5° in terms of vertical accuracy. Therefore, when it is desired to support two or more upper and lower contact wires in the same vertical plane, it is necessary to adjust the inclination angle for each support device. has not been developed.

(Objective of the Invention) The present invention enables accurate erection of overhead contact lines on site by making it possible to easily adjust the installation position of the overhead contact line support device and the inclination angle (verticality) with respect to the installation surface on site. It is intended to.

(Structure of the Invention) The structure of the present invention has a support base consisting of a base part located parallel to the mounting surface and a vertical plate part having a surface perpendicular to the base part. In a contact wire support device configured to attach a bracket for supporting a wire to a vertical plate portion of the support base, the base portion and the mounting surface are connected to each other by fitting a collar with an oblong hole to the base portion side and attaching a fastener. At the same time, the bracket and the vertical plate part are attached through a fastener by fitting a collar with an eccentric hole in at least one place on the bracket side, and a vertical hole is provided in the other places to attach a fastener. This is a mounting structure for an overhead contact line support device, characterized in that it is mounted through a cable.

Both parts 13 and 14 constitute a support stand 18. The base portion 13 is arranged parallel to the mounting surface 5a, and is fixed to the mounting surface 5a with a plurality of (for example, three) fasteners such as anchor bolts 20 as follows.

That is, the anchor bolt 20 is installed perpendicularly (at right angles) to the parapet 5. As shown in FIG. 4, a collar fitting hole 21 having a diameter approximately three times the diameter of the anchor bolt 20 is formed in each portion of the base portion 13 that roughly corresponds to each anchor bolt 20. A collar 22 having an oblong hole 23 into which the anchor bolt 20 is inserted is rotatably fitted into the hole 21 . Each bolt 20 is inserted into the oblong hole 23 of the collar 22, and the nut 24 is screwed onto each bolt 20, so that the base portion 1
3 is fastened to the mounting surface 5a. The collar 22 has a polygonal head 22a for rotation adjustment.

The bracket 15 shown in FIG. 3 is fastened to the vertical surface of a vertical plate portion (a C-shaped member is used in the drawing) 14 by a pair of upper and lower bolts 26, 27 as follows.

That is, in FIG. 5, the vertical plate part 14 has two upper and lower parts.

As shown in FIG. 3, the bracket 15 has substantially horizontal insulator support portions 15a and 15b at both upper and lower ends.
are formed, and the insulators 16 and 17 are fixed to the support portions 15a and 15b, respectively, in an upwardly projecting manner. Both support portions 15a and 15b are preferably formed to extend in opposite directions from each other in terms of insulation and balance. Therefore, both insulators 16 and 17 are located at intervals in the length direction of the contact wire.
Reference numerals 16a and 17a are mounting bolt parts integrally formed with the insulators 16 and 17, respectively, and each bolt part 16a and 17a is fixed to the upper support part 15a and the lower support part 15b by a pair of nuts 40, respectively. Therefore, it is possible to slightly adjust the accuracy in the vertical direction at this location as well.

That is, the mounting position and posture of the base portion 13 within the plane of the mounting surface 5a are adjusted by rotating the collar 22.

When tightening the bracket 15 to the vertical plate part 14, first adjust the horizontal position of the bolts 26 and 27 in the horizontally long elongated hole 28 of the vertical plate part 14, thereby adjusting the horizontal position of the bracket 15, That is, the amount of horizontal protrusion of the contact wires 9 and 10 is adjusted as shown in FIG. However, although this horizontal position is possible by inserting a spacer or liner between the mounting surface 5a and the base portion 13,
From the perspective of the work procedure, it is preferable to form horizontal long holes in the vertical plate portion 14.

Next, by adjusting the rotation of the collar 34 with the eccentric hole 33, the bracket 15 is rotated between the bracket 15 and the vertical plate part 14 so that the bracket 15 is in a vertical position.
Adjust the angle of inclination. That is, even if the mounting surface 5a is not exactly vertical, the bracket 15 can be maintained in an accurate vertical position by adjusting the rotation of the collar 34, and the upper and lower contact wires 9,
10 can be aligned on the same vertical plane H. In addition, when rotating the collar 34, the bracket 15
moves slightly upward or downward relative to the vertical plate portion 14, but this is almost negligible in construction.
