Abstract

An aerial cable treatment system having a cable surface preparation assembly and a coating assembly. The cable treatment system is translatable along an in-situ aerial cable. The cable surface preparation assembly can remove dirt and debris, such as carbon deposit, grease, mud, fertilizers, bird droppings, fungal growth, mosses, soot, ice, and like from aerial cables with varying sizes as it translates along the cable. The coating assembly can apply a coating to the outer surface of the in-situ aerial cable it translates along the cable.

First claim

The invention claimed is:

1. A multi-carriage aerial cable treatment system, comprising:
a first carriage and a second carriage, wherein the first and second carriages are each independently translatable along an aerial cable under treatment, wherein the first carriage comprises:
a first housing having a first longitudinal axis;
a first forward traction wheel and a first rear traction wheel that are each coupled to the first housing and positioned along the first longitudinal axis, wherein at least one of the first forward traction wheel and the first rear traction wheel are drivable to propel the first housing along the aerial cable under treatment; and
a cable surface abrasion assembly positioned to contact the aerial cable under treatment; and

wherein the second carriage comprises:
a second housing having a second longitudinal axis;
a second forward traction wheel and a second rear traction wheel that are each coupled to the second housing and positioned along the second longitudinal axis, wherein at least one of the second forward traction wheel and the second rear traction wheel are drivable to propel the second housing along the aerial cable under treatment;
a coating storage tank;
a coating applicator assembly; and
a coating pump operative to pump a coating material from the coating storage tank to the coating applicator assembly.

2. The multi-carriage aerial cable treatment system of claim 1 , wherein the cable surface abrasion assembly comprises a brush assembly and a motor operatively coupled to the brush assembly.

3. The multi-carriage aerial cable treatment system of claim 2 , wherein the brush assembly comprises a first rotatable hub of stainless steel bristles and a second rotatable hub of stainless steel bristles, and wherein the first rotatable hub of stainless steel bristles and the second rotatable hub of stainless steel bristles are positioned on opposite sides of the aerial cable under treatment.

4. The multi-carriage aerial cable treatment system of claim 1 , wherein the cable surface abrasion assembly comprises a surface preparation inspection system.

5. The multi-carriage aerial cable treatment system of claim 4 , wherein the surface preparation inspection system comprises a plurality of surface preparation inspection cameras.

6. The multi-carriage aerial cable treatment system of claim 1 , wherein the coating applicator assembly comprises any of a nozzle and a foam-based applicator.

7. The multi-carriage aerial cable treatment system of claim 1 , wherein the coating applicator assembly comprises an air delivery assembly positioned to direct an airflow towards the aerial cable under treatment.

8. The multi-carriage aerial cable treatment system of claim 1 , wherein the coating applicator assembly comprises a coating inspection system.

9. The multi-carriage aerial cable treatment system of claim 8 , wherein the coating inspection system comprises a plurality of coating inspection cameras.

10. The multi-carriage aerial cable treatment system of claim 1 , wherein the second housing has a front end portion, and wherein the second rear traction wheel is positioned closer to the front end portion than is the coating applicator assembly.
