JP4017561B2 - Device for supporting the vertical part of armrests for equipment columns made of cylinders - Google Patents

Description

[0001]
[Industrial application fields]
The present invention relates to a support device for a vertical portion of a brace for equipment columns made of a cylindrical body.
[0002]
[Prior art]
In order to mount signal lamps and other equipment, the vertical part of the armature made of a cylindrical body may be attached to the utility pole, and the equipment may be assembled to the horizontal part (horizontal collar) on the upper side. In other words, in order to support the vertical portion on the electric pole, a short cylindrical holding cylinder attached with a band body is provided on the electric pole side, the vertical portion is inserted into the holding cylinder and tightened with a tightening bolt, and a through bolt is attached. There is a structure that prevents the vertical portion (arm bracket) from being displaced due to the loosening of the tightening bolt (for example, Patent Document 1).

[Problems to be solved by the invention]
Since the conventional example adopts a form in which the arm metal and the power pole side are connected by a through bolt penetrating the holding cylinder on the power pole side, the arm metal and the vertical part of the arm metal or the through hole of the holding cylinder are used. A gap is inevitably generated, and the presence of the gap causes a so-called rattling and a stable support state cannot always be obtained. In addition, there is a problem that the plating layer is lost early due to rattling.
[0005]
The present invention was devised to provide a support device having a novel structure that does not have the disadvantages of the conventional example.
[0006]
[Means for Solving the Problems]
The steel plate is bent into a U-shape by welding each edge of a notch-shaped notch provided continuously on the upper and lower pieces and the peripheral side of the vertical part of the arm metal engaged with the notch. The mounting base frame provided with the formed upper and lower part pieces protrudes from the vertical part, and the mounting base frame is fastened to the power pole by a band body. By making the configuration narrower than the outer diameter, even if the function of the welded portion disappears, it can withstand the load in the lying direction of the armband, and thus a robust support device can be provided.

DETAILED DESCRIPTION OF THE INVENTION
The drawings show an embodiment of a support device for the vertical part of the armature for equipment columns according to the present invention, FIG. 1 is a front view, FIG. 2 is a partially enlarged view of FIG. 1, and FIG. FIG. 4 is a side view of FIG. 2 and FIG. 5 is a perspective view of the mounting base frame.
[0008]
In the embodiment, a pair of upper and lower attachment base frames 2 and 2 are provided on a vertical portion 1a of a generally L-shaped arm 1 which is configured by connecting a horizontal portion (horizontal portion) 1b to the upper side of the vertical portion 1a. A pair of band bodies 5 and 5 which are welded 10 and pivotally mounted on an annular base piece 5a formed by a support shaft 3 on the free end side of the mounting base frame 2 are wound around a power pole 8, and the band body 5 The armature 1 is mounted by tightening and tightening a nut 7 at the tip of the bolt 6 projecting from one of the tightening receiving piece 5b through the fastening bolt 6 passing through the tightening receiving piece 5b, 5b on the tip side of the armature. In addition, the present invention is applied to a signal lamp support device in which a signal lamp (not shown) is assembled to the lateral portion 1b of the arm 1.
[0009]
The support shaft 3 in the support device is constituted by a bolt rod, and the bolt rod is combined with a nut to be attached to the attachment base frame 2 and used as a rotation support shaft when the band body 5 is wound around the utility pole 8. .
[0010]
The mounting base frame 2 is formed by welding a reinforcing piece 2 ′ on the free end side (electric pole 8 side) of the main body 2 </ b> A formed by press-molding a steel plate, and is provided with an appropriate long hole in the center portion. A base plate made of a steel plate punched and press-formed to have an appropriate contour shape is bent in a U shape so as to cross the long hole, and is continuously aligned with each other so as to open the center of the bent portion. The main body 2A having the upper and lower part pieces 2a and 2b that are opposed to each other is formed by providing a cutout-shaped notch 9 (consisting of the long holes), and a pair of the reinforcing part pieces at the free ends of the upper and lower part pieces 2a and 2b. The product is welded so as to pass 2 ′ and 2 ′, and is assembled to the brace 1 as described above.
[0011]
The notch 9 provided on the upper and lower pieces 2a and 2b of the mounting base frame 2 so as to coincide with each other has an opening end width narrower than the outer diameter of the vertical portion 1a formed by the cylindrical body of the arm metal 1 (the periphery of the notch 9 is The cut-out circle formed substantially coincides with a part of the cross-sectional circle of the vertical portion 1a), and the arm metal vertical portion 1a cannot be removed from the cut-out 9 through the opening end of the cut-out 9 due to the radial width. The arm 1 is engaged with the vertical portion 1a and the edge of the vertical portion 1a and the notch 9 are welded 10 as described above, so that the arm 1 and the base frames 2 and 2 are integrated with each other.
[0012]
Therefore, in the case of the embodiment, the band body 5 is assembled to the base frame 2 by the support shaft 3, so that the band body 5 is fastened to the utility pole 8 while holding the arm 1 integrated with the base frame 2. As a result, the brace 1 is fastened to the utility pole 8, but the base frame 2 and the band body 5 do not necessarily have the structure of the embodiment.
[0013]
【The invention's effect】
Since the present invention is configured as described above, it is possible to provide a support device having a novel structure that does not cause backlash.
