This is to prevent the installed insulators from getting dirty.0 Because power transmission line towers are located outdoors and are exposed to wind and rain, they are susceptible to corrosion and must be regularly coated with anti-rust coating. This type of steel tower consists of a main body that is erected and an arm that projects laterally from the main body, and a power transmission line is suspended or stretched from the tip of the arm through an insulator. However, since the main body of the steel tower is located far from the power transmission lines, there is little electrical danger, and the painting process is relatively easy, so rust-proofing coatings have been applied to the towers to date. On the other hand, in order to prevent the paint from scattering and staining the area around the steel tower and the insulators, the rust-preventing coating on the arm was done by covering the entire arm with a paint-scattering prevention net or sheet. The tip of the arm is electrically extremely dangerous because it is close to high-voltage live wires, so power transmission must be stopped when anti-corrosion painting is applied, and on lines where power transmission cannot be stopped, the tower itself The actual situation was that only the arm part, which needed anti-rust coating, was left unpainted. Furthermore, in the case of the above-mentioned conventional method, there are various problems such as the cost of materials for nets and sheets, assembly and disassembly costs, etc., and the assembly and disassembly work being carried out at high places with poor footing, which is often dangerous.

のを簡単かつ確実に防止しうるようにしたものである。Therefore, the present invention has been made in consideration of the above points, and when performing anti-corrosion coating near the tip of the tower arm using a painting tool formed by attaching a coating body such as a brush to the tip of a working rod, Hold the operating rod with a paint scattering prevention body attached to its tip, position the paint scattering prevention body below the painted body, and make the paint scattering prevention body follow the movement of the painted body while operating the operating rod. The paint scattering preventer prevents the paint from falling off the paint surface of the arm or the paint body mentioned above, and thereby the tip of the arm can be painted safely without stopping power transmission. This makes it possible to easily and reliably prevent the paint from scattering to the surrounding area.

A is the main body of the steel tower, B is an arm that protrudes sideways from the main body A, and one worker A is working with the work rod 21
Hold the rear end of the working rod 21 of the painting tool 23, which consists of a painting body 22 such as a brush attached to the tip of the arm B, and operate the working rod 21 to apply anti-rust coating to the vicinity of the tip of the arm B. . C is a tension-resistant insulator stretched over the tip of arm B. The other operator port is opened by engaging one hook 12a of the suspension tool 1o to the member 11 of the arm part B, and engaging the seven hooks 17 of the operation rod 15 with the suspension tool 1o. Yu 5
After operating the suspension device 10 to move it along the member 11 to a desired position on the arm part B, the rear end of the operating rod 1 is held, and the approximately central portion of the operating rod 1 is suspended in the air. other hook 1
2b for suspension support. If the paint scattering prevention body 3 at the tip of the operating rod 1 follows the movement of the painted body 22 so that it is always directly below the painted body 22, the painted surface of the painted body 21 and the tip of the arm B will fall off. The paint falls onto the sheet 5. In addition, if the paint is scattered to the sides due to strong winds, please operate the control lever L to remove the sheet from the
By locating it on the leeward side, paint can be prevented from scattering around the tower. The above-mentioned operations can be easily performed with light work since the operating rod 1 is suspended and supported by the suspension tool 1O. When the painting work is completed in this way, the operating rod 1 is removed from the hook 12b, the operating rod 15 is held again, the hanging tool 10 is hooked to the tip hook 17, and the hanging tool 10 is attached to the member 11. Pull it toward you along the hanging device 10.

It is electrically extremely safe because there is no need to approach suspended power transmission lines, and there are various advantages such as there is no need to stop power transmission during work. In addition, strong winds often blow on steel towers, and therefore the paint scattering prevention device described above tends to be blown away by strong winds. Therefore, even when a strong wind blows, the operating rod 1 can be firmly held, and the paint scattering prevention body 3 at the tip can follow the movement of the painted body 22, thereby reliably preventing paint from scattering.

A notch 37 is formed that extends to the center of. 3B
is a sheet-like covering for closing the notch 37,
One end thereof is attached to one side edge of the notch 37. The covering body 38 is made of a material having appropriate flexibility and sufficient electrical insulation, such as rubber, and is normally closed to the notch opening 37, leaving the right end 37a of the notch opening 37, as shown in the figure. is almost covered.

しても実用上差しつかえはない。FIG. 9 shows a situation in which the paint scattering prevention body 33 is attached to the tip of the operating rod 1, and anti-rust coating is applied to the vicinity of the tip of the arm section B, and D is at the tip of the arm section. This is a suspended insulator, and the paint M scattering body 33 is located directly above the insulator. That is, if the operating rod 1 is operated to align the opening 36 with the mounting section 39 of the upper end of the insulator, and the mounting section 39 is moved forward, the mounting section 39 will fit into the notch 37 without pushing the cover 38 upward. When the cover 38 is inserted along the notch and reaches the right end 37a of the notch, the covering 38 closes the notch 37 again. In the bent state, the arm part B is
If the painting is performed directly above the insulator at the tip, the paint dripping from the painted surface of the painted body 22 and the arm part B will fall onto the sheet 35, and the insulator will not become dirty. When the painting just above the insulator is completed in this way, by pulling the operating rod 1 toward you, the attachment part 39 will again push away the coating 38 upwards and separate from the paint scattering prevention body 33. As described above, by using the present paint scattering prevention body 33, it is possible to reliably prevent the hanging type insulator from being soiled by fallen paint. Furthermore, when painting a part of the arm part B other than directly above the insulator, it is preferable to use the paint scattering prevention body 3, but the notch right end 37a of the paint scattering prevention body 33 is small. Therefore, only a small amount of paint falls from the right end portion 37a, so even when painting parts other than directly above the insulator, there is no practical problem even if this paint scattering prevention body 33 is used. There isn't.

ある。As explained above, according to the method of the present invention, it is possible to safely apply anti-rust coating to the electrically dangerous end of arm B with light work without stopping power transmission. It is possible to reliably prevent fallen paint from scattering and staining the area around the steel tower and the insulators, and furthermore, there is no need to cover arm part B with a net or sheet to prevent paint from scattering.
It has various effects such as low cost and extremely high work efficiency.
