Description

[Detailed description of the invention] A. Industrial field of application: For improving pole mounting equipment for attaching electrical equipment such as bypass switches to utility poles, which are used as temporary equipment during uninterruptible construction of high-voltage distribution lines. In particular, the present invention relates to a pole mounting metal device that allows easy pole mounting.

B. Prior art Upgrading and adding equipment to high-voltage distribution lines,
Currently, when carrying out various types of distribution line work such as relining electric wires and replacing insulators, it is not possible to perform power outages even if the power outage is for a short time because the impact on customers is extremely large. Therefore, in recent years, an uninterruptible construction method called the bypass construction method has been adopted.

In this system, a temporary bypass circuit is formed for the line in the construction area, and during construction, power is continuously transmitted to customers in the construction area through this bypass circuit.

By the way, when forming this bypass circuit, a switch specifically for the construction called a bypass switch is temporarily installed on the utility pole in the construction section.

This switch is installed directly in the middle of an existing utility pole in the construction zone, but in the conventional type, when installing the switch on the pole, the switch is attached to the support member attached to the pole. When connecting (installing) or detaching (removing) the hooking member provided on the switch side, as known from Japanese Utility Model Application Publication No. 55-55934, the hooking member provided on the back side of the switch is attached to the pin on the supporting member side. It has a structure that allows the connection holes to fit together.
Therefore, since the connecting hole cannot be made large, it is difficult to fit the two together, and there is a problem that the switch installation work becomes long. Furthermore, fixing the two after they have been connected is troublesome, as it requires a screw-turn operation because of the tightening structure using bolts and nuts.

C. Problems that the present invention aims to solve The present invention solves the operational problem of difficulty in connecting or separating the support member attached to the utility pole and the hooking member integrally attached to the switch. This allows for one-touch installation or removal.

is urged to protrude from the one open end 36b.

It should be noted that the pole mounting device consisting of the supporting member 21 and the hanging member 16 is not only used for the bypass switch according to the embodiment of the present invention, but also for mounting various electrical equipment temporarily installed in the middle of a utility pole. Needless to say, it can be widely applied as a post metal fitting device.

Next, the supporting member 21 and the hooking member 1 having the above configuration are
The usage method (installation method) for 6 will be explained.

First, the support member 21 is attached to the utility pole 11 in the construction section where the bypass switch 1 is to be attached at an appropriate position using the fastening metal fittings 23. Next, the bypass switch 1 with the hanging member 16 integrally attached to the back surface 2c is lifted to the height of the mounting position of the support member using a winch that hooks a rope to the hanging hook 5 on the upper surface.

Then, insert the bulging part 18b of the latching fitting 18 provided above the switch side into the receiving plate fitting 32 of the support member attached to the utility pole side from above, and then slide it left and right to the latching recess 18a. is fitted into the deep portion 31a of the receiving fitting 31 and positioned. In this state, the positioning fitting 33 of the deep portion 31a fits into the recess 18a, so that the positioning of the bypass switch 1 with respect to the base fitting 22 in the left-right direction is also performed. Further, since the lower part of the switch protrudes forward, the bulging portion 18b follows the slope of the guide member 22d. Next, push the lower side of the switch backwards (toward the utility pole) until the engaging metal fitting 19 touches the base metal fitting 22. Then, each engaging piece 19a, 1 of the switch positioned as described above
9a enters toward a position where it overlaps the surface of the locking metal fitting 35 on the side from which the locking tool 37 protrudes. In the process, the engaging piece 19a pushes the tip 37a of the locking tool 37, so the tip 37a of the locking tool is pushed into the storage body 36 and temporarily retracts. Then, when the engaging hole 19b of the engaging piece matches the position of the locking tool 37 after a slight movement, the tip 37a of the locking tool 37 that has been recessed in the storage body is automatically moved by the biasing force of the coil spring 40. It protrudes from the open end 36b of the storage portion and fits into the engagement hole 19b to complete the installation.
In other words, when the switch is positioned and latched on the upper side, by pushing the lower side backward, the lower side is automatically fitted into the state, and can be installed with one touch.

To remove the switch, perform the above procedure in reverse. That is, the lower side of the switch is pulled forward (away from the utility pole) to remove the engaging piece 19a from the locking metal fitting 35.
In this case, the tip 37a of the locking tool 37 that protrudes from the storage body 36 by the coil spring 40 is
Since a is formed in a spherical or curved shape, the lever can be released from the fitted state with a small amount of force. Further, since the guide member 22d is tilted backward, the bulged portion 18b is allowed to tilt backward.

After the lower side of the switch has been removed in this way, the switch is then pulled up upward by the rope hooked to the hanging hook on the upper surface, and the upper latch fitting 18 is attached to the receiving fitting 31.
Remove from. The switch is then lowered to the ground using a winch.

Effects of the invention As described above, when installing a switch on a pole, the present invention provides the following advantages: By simply pushing the lower side of the switch backwards or pulling it toward you, the lower side can be smoothly connected or disconnected, making this type of conventional type of installation possible. It has the advantage of being much easier to install and remove than metal fitting devices.

In particular, in the present invention, at the upper position on the back surface of the switch main body 2, a dimension W1 is formed which is significantly larger than the width dimension W3 of the receiving plate metal fitting in order to temporarily hang it on the above-mentioned receiving metal fitting 31. A bulging portion 18b is provided at the center, fixing portions 18c on both sides are fixed to the switch, and a hook is provided for fitting the bifurcated deep portion 31a of the receiving fitting 31 to the lower surface of the central position of the bulging portion 18b. A locking fitting 18 having a locking recess 18a is attached, and a receiving plate fitting 3 is provided on the front side of the base fitting 22 at an upper position thereof.
2 is located, a guide member 22d tilted backward is located, and a receiving metal fitting 31 is attached which has a bifurcated shape with a funnel-shaped opening at the top. When hanging the latch 18,
The inner space of the bulging portion 18b is significantly larger than that of the receiving plate metal fitting 32, which has the effect of allowing easy temporary latching.

Further, after temporary latching, when the switch is slid from side to side, the latching recess 18a easily fits into the deep part 31a of the receiving metal fitting, thereby providing the effect of positioning.

In addition, since the guide member 22d is tilted backward, it is convenient to introduce the bulge 18b, and when the lower part of the switch protrudes forward, the bulge 18b can be tilted backward. It also has the practical effect of making the installation process easier.
