実に行えるようにしたものである。[Detailed description of the invention] In places where electric railway lines have a cant angle, in order to avoid uneven wear of the rigid overhead contact line, the trestle supporting the overhead contact line must also be installed at an angle corresponding to the cant angle. A previous idea (Utility Application No. 76,626, 1983) was made to make the angle of inclination of the pedestal adjustable, but the present invention improves on this, making it easier to adjust the angle, and making it easier to fix the frame after adjustment. This is to ensure that this can be done.

is fixedly suspended from the ceiling of the tunnel via insulator G. A suspension nut 2 is screwed onto the lower end of the threaded rod 1 and can be fixed to the threaded rod by an upper lock nut 3. The hanging nut 2 has a collar 2a at the lower end of the body.
and a spanner hook notch 2b at the upper end. A detent washer 4, a main body 5, and an arc plate 8 are inserted into the body of the hanging nut in this order from above.
It is supported by the collar 2a. The washer 4 has a hole 4a that engages with the notch 2b and a diametrical protrusion 4b.
The main body is prevented from rotating around the threaded rod by bending it and inserting it into the main body long hole 5b described below. The main body 5 has a semicircular part with diametric wings 5a protruding from both ends, and the semicircular part has a circumferential elongated hole 5b in the center through which the threaded rod 1 can be inserted, and a wedge piece to be described later on the inner surface. 10, and side walls 5d are provided on both sides. In addition, the wing 5a can support a T-shaped aluminum pedestal 7 using an attached support metal fitting 6.
A contact line (not shown) is fixed to the lower end of this Aryo frame. The arc plate 8 is slidably inserted into the semicircular part of the main body, and has a hole 8a in the center through which the threaded rod 1 can be inserted.
is worn. Further, its end face is an inclined surface 8b having an inclination angle α. A hole is bored in the side wall 5d on both sides of the semicircular portion of the main body 5, and a screw shaft 9 in the axial direction is rotatably supported. The wedge piece 10 has a screw hole 10a that is screwed into the screw shaft 9, and an inclined surface 10b corresponding to the inclined surface 8b of the arc plate, and can move forward and backward along the guide surface 5c of the main body by rotation of the screw shaft 9. ing. By moving back and forth, the main body can be tilted with respect to the arcuate plate 8 that comes into contact with the inclined surface.

材によつて支持されているからである。 The present invention is constructed as described above. If the main body in the state shown in FIG. 1 is to be tilted downward to the right, the screw shaft 9 and wedge piece 10 may be provided only on the right side inside the semicircular portion as shown in the figure. If it is sloped downward to the left, install it only on the left side. After adjusting the inclination, remove the hanging nut 2.
This device is locked by tightening the lock nut 3 and pressing the lower surface of the aluminum frame 7 with the support metal 6 as shown in FIG.
No slack will occur between 0b. This is because the aluminum frame 7 has a considerable weight and is supported by other members along its extension.

冒頭で述べた先願の装置では傾斜角度の調節は
できるが、その角度位置に固定する作業が、他の
装置を用いる困難なものとなつていた。これに対
し本考案では傾斜調節後、そのままロツクできる
ようにしたことが特徴である。 Although the device of the prior application described at the beginning allows adjustment of the tilt angle, it is difficult to fix the device at that angle using other devices. In contrast, the present invention is characterized in that it can be locked directly after adjusting the inclination.
