A portable special soft ladder for inspection of transmission line wiring that can be operated by one person

Abstract

The invention discloses a special portable power transmission line routing inspection rope ladder capable of being operated by a single person. The rope ladder is characterized in that an upper hook (1) is connected with a tightener (2), the tightener (2) is connected with a telescopic casing pipe (3) through a steel wire rope (5), the telescopic casing pipe (3) is connected with at least one pedal unit through the steel wire rope (5), the pedal unit at the lowest end is connected with a turn buckle (7), the turn buckle (7) is connected with a lower hook (8), each pedal unit comprises a pedal (6), two press-joint pipes (4) and a section of steel wire rope (5), each of two ends of each pedal (6) is connected with one press-joint pipe (4), and the pedals (6) are connected with the steel wire rope (5) through the press-joint pipes (4). The rope ladder is simple in structure, convenient to operate and portable, the labor cost is saved, and the working efficiency is improved.

Description

[0001] Technical field: [0002] The invention relates to a portable and single-person-operable special soft ladder for inspection of transmission line alignment, which is widely used in the work of upper and lower synthetic insulators in the maintenance process of overhead transmission lines, and belongs to the field technical field of transmission maintenance. [0003] Background technique: [0004] Overhead transmission lines are mainly composed of towers, foundations, conductors, lightning conductors, insulators, fittings and grounding devices. Insulators mainly play the role of supporting or suspending conductors in overhead transmission lines, and at the same time insulate conductors from towers. [0005] Insulators in actual operation may undergo bending, torsional loads, compression loads and alternating mechanical loads, which may cause changes in the performance of the insulators, or even fractures. Therefore, the State Grid Corporation of China clearly stipulates in...

AI Technical Summary

Problems solved by technology

[0006] In the actual line routing inspection work, the main problem is that an operator cannot independently complete the work from one base tower to the cross arm by operating the ladder alone from the other base tower.

From the above process, it can be seen that the hanging ladder used for the upper and lower insulators needs the cooperation of multiple people to complete the work. The process is relatively cumbersome and requires more cooperation personnel.
