Description

[Detailed Description of the Invention] The present invention relates to a manual opening/closing operation mechanism for a remotely controlled pole-mounted switch.

An operating lever is connected to a switch installed on a pole, and this operating lever is suspended and supported along the utility pole. When an attempt is made to open or close the switch by rotating the operating lever, the lower end of the operating lever The handle must be connected perpendicularly to the handle, but in order to be able to easily rotate the handle, it is necessary to make the handle a certain length. Therefore, if you leave the long horizontal handle in place other than when opening or closing, you may accidentally turn it while working on a pole, or use it as a scaffold, which may damage the operating mechanism. Furthermore, since there is no locking means in the opening or closing position, there is a possibility that the operating handle may be manipulated intentionally.

The present invention was devised to solve the above problem, and its purpose is to suspend and support an operating rod connected to a pole-mounted switch via a link, and to The operating handle is attached to the electric pole via a mounting member so as to be rotatable in the vertical direction, and a locking member is attached to the utility pole to lock the operating handle vertically in the closed or open position. Furthermore, by locking the operation handle with a locking means, even a fairly large switch can be opened and closed with a relatively small force, and damage caused by wind pressure, etc. can be prevented, and it can be operated accidentally or tampered with except when opening and closing. It is an object of the present invention to provide a manual opening/closing operation mechanism for a pole-mounted switch which is capable of reliably preventing such problems and is also aesthetically superior.

This is a spring interposed between the pin 32 and the lower surface of the pin 32, and always urges the retaining pin 32 downward. Then, the operation handle 25 is inserted into the fitting hole 2.
7, the retaining pin 3 is inserted into the inverted truncated conical locking hole 25c provided on the outer periphery of the handle 25.
The lower ends of the handles 25 and 2 are engaged to prevent the operation handle 25 from being easily removed. Note that a spacer 37 is interposed between the bottom surface of the cylinder 31 and the locking pin 34 to adjust the lower limit of the locking pin 32.

Further, numeral 38 is a display plate screwed onto the surface of the operating rod 7 for displaying the opening movement direction of the operating handle 25.

Next, the operation of the manual opening/closing mechanism for the switch configured as described above will be explained.

Now, in FIG. 5, the operating handle 25 is in an upright state, its lower end is inserted into the fitting hole 28 for regulating the closing position of the support plate 21, and the lock 3 is inserted into the locking hole 25b.
This shows the closing lock state where 0 is applied. To open the switch from this state to a full stop, remove the lock 30, pull up the operating handle 25 along the elongated hole 25a, pull it out from the fitting hole 28, and rotate the support bolt 26 at the center. Fifth
Rotate 90 degrees clockwise to make it horizontal.
After that, move the operating handle 25 to the left along the long hole 25a, insert it into the fitting hole 27 of the operating rod 7, and when the locking hole 25c at the tip is locked with the retaining pin 32, operate the operating handle 25. It rotates clockwise in Figure 6 around the rod 7. Then, the operating rod 7 is rotated in the same direction, and the rotation is transmitted to the operating shaft 6 via the operating arm 11, interlocking link 12, and driven arm 13, so that the switch 1 is opened. At this time, the pointer 18 is moved to the open display position by the operation rod 7, and the pointer 17 is also moved by the operation rod 14 and the driven lever 1.
6 and the rotation shaft 15 to the open display position.

Once the operating handle 25 has been rotated to the open state, the operating handle 25 is pulled out from the fitting hole 27 of the operating rod 7 against the locking force of the retaining pin 32 and returned to the vertical state. When the lock 30 is inserted into the opening position regulating fitting hole 29 of the support plate 21 and the lock 30 is engaged with the locking hole 25b, the opening operation is completed.

Now, in the embodiment of the present invention, the driven arm 13 and the interlocking link 12 are connected to the operating shaft 6 of the switch 1.
The operating rod 7 is rotatably articulated via the operating arm 11, and the operating lever 7 hangs downward along the utility pole 2, and the operating handle 25 is articulated to the lower end of the operating lever 7. Therefore, even a fairly large switch can be opened and closed with a relatively small force, damage caused by wind pressure, etc. can be prevented, and the appearance can be improved.

In addition, in the embodiment of the present invention, the operating handle 25
A long hole 25a is provided in the hole 25a so that it can be inserted into and removed from the fitting hole 27 of the operating rod 7 and the fitting holes 28 and 29 of the support plate 21, respectively, and the operating handle 25 is locked when not in opening/closing operation. 30 to lock the operating handle 25 in the vertical position, it is possible to reliably prevent the operating handle 25 from being intentionally pulled out of the fitting holes 28 and 29 and being operated illegally. Since the operating handle 25 is held along the line 7, it is possible to prevent the operating handle 25 from being accidentally pushed and opened/closed while working on the pole.

In the above embodiment, when the operating handle 25 is inserted into the fitting hole 27 of the operating rod 7, the retaining pin 32 is inserted into the locking hole 25c of the operating handle 25.
However, by doing so, it is possible to prevent the operating handle 25 from slipping out unexpectedly during rotation, and to ensure reliable and safe opening and closing operations.

In this way, the present invention installs a switch on a support frame fixed to a utility pole, and an operating lever that is linked to the opening/closing mechanism of the switch via a link is suspended downward along the utility pole. An operating handle is attached to the lower end of the unit via a mounting member so as to be rotatable in the vertical direction, and the base end of the operating handle, which is placed horizontally, is locked to the operating rod so that it can be opened and closed. Further, a locking member is attached to the utility pole to lock the operating handle vertically in a closed or open position, and the locking member locks the operating handle. By making this operation handle lockable with a locking means in the closed state, even a fairly large switch can be opened and closed with a relatively small force, and it is possible to prevent damage caused by wind pressure, etc., and to prevent accidental accident when not opening or closing. Alternatively, it is possible to reliably prevent tampering with the operation, and it also has the effect of being aesthetically superior.
