Description

[0001]
[Industrial application fields]
The present invention relates to a signal lamp device column apparatus.
[0002]
[Prior art]
A signal lamp is suspended from an arm that protrudes from a power pole, and a connection fitting comprising a central piece and a side piece that stands up against the central piece on the upper surface of the distal end of the arm is attached to the central piece. While tightening with a fastening bolt, the signal lamp equipment column device is connected to the side piece of this connection fitting with the lower end of the reinforcing support attached to the utility pole at the upper end, and the side piece is connected to the side shaft. It is well-known without mentioning a specific example, and this known structure has a connection bolt arranged on the side piece of the connection fitting fastened to the arm metal with the tightening bolt so as to be positioned immediately above the tightening bolt, This connection bolt is used to pivot the lower end of the reinforcing support to the side piece (connection fitting) (as shown in FIG. 4 because no concrete example can be shown).
[0003]
[Problems to be solved by the invention]
The above reinforcing support is a cantilever arm that handles the load of a signal lamp or the like and stretches between the arm metal tip and between the power poles to increase load resistance. However, a tension acts on the reinforcing support, and it appears on the connection fitting assembled with the connection bolt through the connection bolt which is the fulcrum of the tension. A load is applied to the part (or a nut screwed to the bolt), and the connection fitting tries to rotate with the tightening bolt part as a fulcrum. As a result, the tightening bolt part is deformed, and the durability of the entire apparatus is hindered. There is a time.
[0004]
The present invention has been devised for the purpose of eliminating the disadvantages of such conventional examples.
[0005]
[Means for Solving the Problems]
A signal lamp is suspended from an arm that protrudes from a power pole, and a connection fitting made up of a center piece and a side piece standing up against the center piece on the upper surface of the tip of the arm metal, Tighten a fastening bolt through a through-hole provided in the piece, and tighten the lower end of the reinforcing support with the upper end attached to the utility pole to the side piece of the connection bracket to the lower end and the side piece. A configuration in which a connection bolt is passed through and connected to the provided through hole, and the through hole provided in the side piece is positioned above the through hole provided in the central piece, and is further disposed in the position on the utility pole side. It is what.

A device 4 is suspended and a reinforcing support 5 is stretched between the tip and the utility pole 1.
[0008]
The reinforcing support 5 is attached to a tightening bolt 6a of a band body 6 fastened to the utility pole 1 with the upper end of the support bracket 2 positioned (not shown, but the tightening bolt 6a passes through the ring piece on the upper end. The ring piece 5a provided at the lower end is connected to the tip of the arm metal (comprising a rectangular tube) 3 via the connection fitting 7.
[0009]
The connection fitting 7 is composed of a central piece 7a and side pieces 7b, 7b provided on both sides of the central piece 7a. The connecting piece 7 has a central portion 7a to a lower portion of the side pieces 7b, 7b at a substantially central portion in the longitudinal direction. An engagement notch 8 is provided, and a through hole 10 for passing through a tightening bolt 9 is formed at the center of the central piece 7a on one side of the engagement notch 8, and the side pieces 7b and 7b on the other side. Near the upper corner, through holes 12 and 12 for penetrating the connecting bolt 11 are provided, and the through hole 12 is located above the through hole 10 for the fastening bolt 9 provided in the central piece 7a. , Provided on the electric pole 1 side (that is, the upper end side of the reinforcing support 5).
[0010]
The connection fitting 7 includes upper and lower mounting pieces 13 and 13 each composed of a central piece 13a and 13'a and a rising piece 13b and 13'b that are connected to the central piece 13a and 13'a. ′ And the tightening bolt 9 and the nut 14 screwed to the tightening bolt 9 to fasten the end of the arm 3. That is, the central piece of the upper mounting piece 13 from the through hole 10 side of the central piece 7a of the connection fitting 7 that is overlapped with the upper mounting piece 13 so that the one rising piece 13b is engaged with the engagement notch 8. 13a, the arm bracket 3, the closing frame 15, and the through hole 10A, 10B, 10C, 10C, 10B 'provided in each of the central piece 13'a of the lower attachment piece 13', the fastening bolt 9 is passed through, The connecting fitting 7 is attached to the tip of the arm metal 3 by screwing and tightening the nut 14 to the bolt tip protruding from the through hole 10B ′ provided in the center piece 13′a of the side attachment piece 13 ′.
[0011]
Then, the side piece 7b, 7b of the connection fitting 7 fastened to the tip of the arm metal 3 by the fastening bolt 9 is inserted into the through hole 12, 12 provided in the side piece 7b, 7b. , 7b, the connecting bolt 11 is passed through the ring piece 5a at the lower end of the reinforcing support 5 and the nut 16 is screwed to the tip of the bolt protruding from the side piece 7b. The lower end side of the support 5 is connected to the ring piece 5a.
[0012]
The reinforcing support 5 connected to the side pieces 7b, 7b of the connection fitting 7 by the connection bolt 11 is operated by operating the tightening (length) adjusting means (turn buckle device) 5b provided at the intermediate portion of the support 5. The length of the reinforcing support 5 can be adjusted, and the tightening bolt 9 for attaching the connection fitting 7 to the arm metal 3 at a position extending from the axis a of the reinforcing support 5 is provided. The reinforcing support 5, the connection fitting 7, and the arm metal 3 are assembled to each other so that the through hole 10 for penetration is disposed.
[0013]
Then, the brace 3 having the connecting fitting 7 attached to the tip thereof by the above-mentioned means (by tightening with the fastening bolt 9 or the like) is attached to the utility pole 1 using the support fitting 2 at the base, and is reinforced at the ring piece 5a. The lower end of the supporting support 5 is connected to the connection fitting 7 (the side piece 7b) using the means, that is, the connection bolt 1, while the fastening bolt of the band body 6 assembled to the utility pole 1 above the support fitting 2 The upper end of the reinforcing support 5 is assembled to 6a, and the through hole 10 is formed on the axis of the reinforcing support 5 by adjusting the position by moving the band body 6 along the power pole 1 or by appropriately operating the tightening adjusting means 5b. The signal lamp device 4 is hung on the arm bracket 3 so as to obtain the pillar device of the embodiment.
[0014]
The closing frame 5 is formed of a U-shaped metal frame and is attached to the arm metal 3 with the tightening bolt 9 and the nut 14 screwed into the bolt 9 by being fitted to the end of the arm metal 3. The upper and lower mounting pieces 13 and 13 ′ are for mounting the signal lamp 4 on the armrest 3.
[0015]
Further, there is no problem even if the head of the tightening bolt 9 and the nut 14 are arranged upside down.
[0016]
【The invention's effect】
Since the present invention is configured as described above, by adjusting the upper end of the reinforcing support, that is, the mounting position with the utility pole, the through hole on the side of the connecting bracket is on the extension line of the axis of the reinforcing support, Even if not, it is arranged close to the extension line and copes with the tension acting on the reinforcing support as much as possible, and external force in the direction of turning up of the connecting metal fitting with the tightening bolt as a fulcrum hardly acts. The apparatus can be provided, and therefore a robust signal lamp mounting apparatus can be provided.
