JPS59747Y2 - Installation structure of discharge lamp ballast - Google Patents

Description

[Detailed description of the invention] The present invention relates to a structure for mounting a ballast for a discharge lamp inside a lighting pole.The purpose of this invention is to allow the ballast to be mounted inside the pole easily, quickly and reliably. Provides a mounting structure for

Conventionally, in order to install a ballast inside a lighting pole, as shown in FIG. Hang the ballast 3 on the hook 4 by turning it as shown by the dashed line, using your hands or by feeling. The stabilizer 5 was hooked onto the hook 6 while being turned.

In such conventional installation, in the case of the upper ballast 3:
It takes time to support the heavy ballast with both hands and rely on groping or feeling, and it is dangerous because it is impossible to confirm whether it has been caught on the hook 4. In the case of the lower ballast 5, the heavy ballast There is a risk of not being able to support the ballast with your fingers and accidentally dropping it into the pole.Moreover, the pole contains power cables, secondary wiring, etc., and attaching and detaching the ballast is time-consuming and uncertain. Met.

In the figure, 7 is a cut-out switch, 8 is a cup 1-out switch mounting plate, and 9 is an opening lid.

The present invention has been devised in view of these drawbacks, and embodiments will be described below with reference to the drawings.

FIG. 2 is a perspective view showing the lower part of the lighting pole. An opening 11 for inserting a ballast is formed in the lower side of the pole 10 made of steel pipe, and the inner wall of the pole facing the opening 11 is provided with an opening 11 for inserting a stabilizer. A bolt 12 for attaching a mounting bracket is fixed perpendicularly to the inner wall surface, and the opening 11 is covered with a lid 13.

In order to insert the stabilizer through the opening 11 and fix it inside the pole, first, as shown in FIG. Then, fix the ballast receiving part 15 to the mounting bracket 17 having the ballast hook part 16 at the lower end to the bolt 12 using the nut 18, and then attach the upper ballast 19 to the receiving part 1 of the mounting bracket 17.
5, as shown in FIG. 4, the lower stabilizer 20 is placed in the pole from below so as to be dropped, and the lower stabilizer 20 is attached in advance to a hanging tool 21 as shown in FIG. At the same time, to increase safety, fit the safety hook ring 23 onto the bolt 12, and then attach the cutout switch 24 from above by tightening the nut 25. Install by screwing into bolt 12.

Note that the plurality of holes 14 provided in the mounting bracket 17 are connected to the ballast 1.
This is to adjust the mounting height according to the size of the 9.20.

Moreover, the hanging fitting 21 shows one embodiment, and the mounting state of the stabilizer 20 is as shown in FIGS. 6 and 7, and 26 in the figure is a set screw.

As described above, in the present invention, the upper ballast receiving part 15 and the lower ballast hooking part 16 are within the range visible from the opening 11, so there is no need to grope to install the upper ballast 19 as in the conventional case. It can be done reliably, safely and quickly while visually checking.

In addition, the lower stabilizer 20 is connected to the hook portion 16 via the hanging tool 21.
Since it can be installed simply by hooking it onto the ballast, it can be installed easily and reliably, and there is no danger of having to support the heavy ballast with your fingertips as in the past.

Furthermore, since the inside of the pole 10 can be machined by simply erecting one mounting bolt 12 on the inner surface of the pole, it is superior to conventional ones in terms of cost and workability.
