題があった。For live line work such as cleaning insulators on power transmission towers and detecting defective insulators, work equipment such as cleaning devices and defective insulator detectors are attached to the tip of long work rods made of electrically insulating material. This is done by the worker holding the rear end of the work rod, touching the work equipment to the insulator, and operating the work rod, but since the distance from the worker's position on the tower to the work position is not constant, , the length of the working rod must be changed appropriately depending on the distance. Conventionally, the length of the working rod can be changed by forming the working rod by connecting several short rods and increasing or decreasing the number of connected rods, or by preparing a variety of working rods of different lengths and changing them as appropriate. There were methods to replace the parts, or to have the worker move and change the working position, but both methods were complicated and had problems with safety and workability when carried out on steel towers with poor footing.

By doing so, both short rods are firmly connected by the wedge action, and by doing so, the length of the working rod can be easily adjusted.

A short hollow rod 1b with a medium diameter is slidably inserted into the short rod a, and a short rod IC with a small diameter is slidably inserted into the short hollow rod 1b, and a cleaning device is installed at the tip of the short rod IC. 2 is installed. 6. The rods 1a, lb, and lc are tapered rods, and the medium-diameter short rod 1b slides freely inside the large-diameter short rod lc, but is designed so that it cannot be pulled out from the large-diameter short rod 1a. , the small-diameter short rod 1a also slides freely within the medium-diameter short rod 1b, but is not pulled out from the medium-diameter short rod 1b. Reference numeral 3 denotes a retaining member that is slidably fitted into each of the short rods 1b and lc, and is made of an elastic material such as vinyl chloride resin, see FIGS. 3 and 4 below. I will explain while doing so.

に適度に摺接する。The retaining member 3 consists of an insertion part 3a formed by tapering off a substantially cowl portion of a cylindrical body, and a short cylindrical grip part 3b connected to the insertion part 3a. The fingers gradually increase in size from the tip to the base. Also, the grip part 3
A cut groove 3c is formed extending from b to the base end of the insertion portion 3a, so that the stopper member 3 can be expanded and contracted. Also, the grip part 3b
The outer surface is knurled to prevent slipping. As mentioned above, the 6 rods 1'bXlc are tapered rods that taper from the base end to the tip.
Corresponding to the change in the outer diameter of c, the stopper 3 expands and shrinks due to its own elasticity and the action of the kerf 30 to form 6 rods 1b and IC.
Appropriate sliding contact.

材3を6杆の間に強制挿入すればよい。Pull out 1c from the 6 rods 1a and lb and extend it to an appropriate length, and forcefully insert each stopper 3 between the 6 rods 1a and lb and lb and lc by gripping s3b. Here each stopper 3
As shown in 9 above, the thread of the insertion part 3a gradually increases from the distal end to the proximal end, and due to its wedge action, it is forcibly inserted between the six rods, and due to sliding friction, the six rods are Strongly connect. After adjusting the working rod 1 to the desired length in this way, the worker holds the rear end of the working rod 1 and cleans the insulator 4 by touching the cleaning device 2 at the tip to the insulator 4 ( (See Figure 5). Next, when you want to change the length of work rod 1,
Grip the grip part 3b of the fastening material 3 and pull out the fastening material 3 between the six rods, adjust the six rods to the desired length by sliding and expanding and contracting them, and forcefully insert the fastening material 3 between the six rods again. Bye.
このようにして洗浄作業が終了し、次の作業場所へ移動
したり鉄塔から地上へ降りる場合には、運搬の便のため
に再び第1図に示すように作業杆1を短縮する。After the cleaning work has been completed in this way, when moving to the next work site or descending from the steel tower to the ground, the working rod 1 is shortened again as shown in FIG. 1 for convenience of transportation.
以上のように本作業杆1は各短尺杆1a、1bXlaを
