いる。 An insulated operating rod having a structure in which a guide is provided at the connecting portion of the support insulator tube, and a joint of the insulated operating rod is slidably fitted and supported on the guide to prevent buckling of the insulated operating rod, There is a conventional device shown in FIG. 1, which is constructed as follows. In FIG. 1, 1 is a peeling tube, 2 is an O-ring, 3 is an upper guide, 4 is an intermediate guide, and 5 is an intermediate flange, which allows the multi-stage support insulator tube 11

クルである。 The support assembly 12 is placed on an operating device 16 that also serves as a stand as shown in FIG.
is fixed. Next, we will discuss this working method. In FIG. 3, 12 is a support assembly, 17 is a lifting tool, 18 is a crane wire rope, 16 is an operating device, and 16a is a rod for connecting with the insulated operating rod 10 of the operating device 16.
b is the outer box of the operating device. As can be seen from FIG. 1, in the tripped state, the pin hole 8a of the lower rod end 8 of the insulated operating rod 10 is inside the lower insulator tube 1 of the support insulator 11, so the pin hole 8a is used to remove the rod of the operating device 16. The lower rod end 8 cannot be pin-coupled to 16a. Therefore, it is necessary to pull out the insulating operating rod 10 downward in order to perform the pin connection, and this work and the work of holding and lifting the insulating operating rod 10 and the multi-tiered support insulator tube 11 all at once are carried out by the lifting tool 17. It is carried out using Figure 4 shows lifting tool 1
7, the lifting tool 17 is fixed to the upper guide 3 of the support tube 11 with a bolt 17c, and is supported through the support bolt 17a through the pin hole 6a of the upper rod end 6 of the insulated operating rod 10. The support bolt 17a is inserted into an elongated hole 17b formed in the side wall of the lifting tool 17 so as to be slidable in the vertical direction. Further, FIG. 4 shows a state in which the support part assembly 12 is lifted up, and in this state, the insulating operation rod 10 is lowered by its own weight, and the support bolt 17 is attached to the lower end of the elongated hole 17b.
It stops when a is supported. In this state, the position of the lower end of the elongated hole 17b is determined so that the pin hole 6a of the upper rod end 6 of the insulated operating rod 10 has a size that allows pin connection. As mentioned above, the pin hole 6 of the upper rod end 6
A is used, so a dimension L3 is required between the upper guide 3 and the support pin 17a. Therefore, in the tripped state, a dimension L 1 (see FIGS. 1 and 2), which is the sum of the dimension due to the overstroke of the operating device, is required between the pin hole 6a and the upper guide 3. Note that 18a in FIG. 4 is the wire rope 18.
This is a shackle for connecting the lifting tool 17 to the shackle.

きくしなければならないという欠点があつた。 As mentioned above, in the conventional method, the lifting tool 17 must be used to perform the pin connection, and for this purpose, the connection between the link mechanism 14 and the upper rod end 6 and the upper guide 3 is There was a drawback that the dimension L1 between the ribs was larger than that in the case where the lifting tool 17 was not used, and therefore the rib tank 13 housing the link mechanism 14 had to be larger as well.

ある。 This invention was made in order to eliminate the drawbacks of the conventional ones as described above, and by providing a protrusion on a part of the outer periphery of the joint that connects the insulating tube of the insulated operating rod and supporting it on the upper surface of the guide. The purpose of this invention is to provide an economical breakout by eliminating the need for a complicated lifting tool and by making the rib tank smaller.

ている。 FIG. 5 shows a support assembly 12 according to an embodiment of the present invention, and the same reference numerals as in FIG. 1 in FIG. 5 indicate the same or corresponding parts, and in this embodiment, as also shown in FIG. A flange-shaped protrusion 7 that protrudes toward the outer circumference from the inner diameter of the intermediate guide 4 is provided on the upper outer circumference of the intermediate joint 7 that connects the insulating tube 9 of the insulated operation rod 10.
A is provided. 5 shows a state in which the insulated operating rod 10 can be pin-coupled to the rod of an operating device as shown in FIG. 3 using the pin hole 8a provided in the lower rod end 8 of the insulated operating rod 10.

１３の寸法も小さくできる。 This insulated operating rod 10 is supported by the protruding portion 7a of the intermediate joint 7 against the upper surface of the intermediate guide 4, and the insulated operating rod 10 does not move downward any further, so that the upper rod end 6 is attached to the multi-tiered support member. There is no risk of the tube 11 coming off the upper guide 3.
Also, in this state, the pin hole 8a of the lower rod end 8
The dimensions are sufficient for the pin to be connected to the rod of the operating device. Therefore, when lifting the support assembly 12, the pin hole 6a of the upper rod end 6
is allowed to enter the inside of the upper guide 3, so a blind cover (not shown) is attached to the upper end of the upper guide 3 to prevent the insulated operating rod 10 from entering the upper side, which occurs when it is set up from a horizontal position. If the reverse movement of the insulated operating rod 10 is prevented, there is no need to hold the insulated operating rod 10, and a conventional complicated lifting tool is also no longer necessary. In addition, considering that the support part assembly 12 is sent to the installation site with a blind lid for shipping attached, it is extremely convenient to use the blind lid when supporting and connecting to the operating device. Also,
When the lifting tool is no longer necessary, it is also no longer necessary to take the dimension L 3 (see Fig. 4) between the upper guide 3 and the support bolt 17a, so as shown in Fig. 6, the link mechanism 14 and the upper Dimension L 2 between the connecting part of the rod end 6 and the upper guide 3
can be made smaller than the conventional dimension L1 , and therefore the size of the rib tank 13 that accommodates the link mechanism 14 can also be made smaller.

The protrusion 7b may be provided on the
In addition, as shown in FIG.
c may be provided. Furthermore, there may be three or more insulating tubes that make up the insulated operation rod, two or more joints that connect these tubes, and two or more guides that slidably fit the joints. In this case, one joint may have a protrusion. All you need to do is set up a section.
