AI Technical Summary

Technical Problem

When the telescopic arm of the insulated boom car is frequently used, the performance of the nylon slider will decline, resulting in damage to the insulating coating and degradation of the insulation performance, threatening the safety of the operator.

Method used

A protective mechanism assembly is designed, including adding a first rolling walking mechanism on both sides of the telescopic arm, and adding a second rolling walking mechanism below the bottom of the telescopic arm so that the telescopic arm reduces friction through rolling friction during operation and maintains good insulation performance.

Benefits of technology

Through rolling friction, the friction resistance between the telescopic arm and the outer arm is reduced, the service life of the telescopic arm is extended, the stability of the insulation performance is ensured, and the operation safety is improved.

Abstract

The utility model provides a protection mechanism assembly for a telescopic arm of an insulated boom truck. The protection mechanism assembly comprises an outer arm and the telescopic arm arranged in the outer arm. The mounting seat is mounted on the outer arm; the first protection device is arranged on the mounting seat; the first protection device comprises a first rolling walking mechanism, penetrates through the installation base and abuts against the two side arms of the telescopic arm. The second protection device is arranged below the bottom of the telescopic arm and is used for supporting the telescopic arm; the second protection device comprises a second rolling walking mechanism and abuts against the bottom of the telescopic arm. When the telescopic arm works, through rotation of the first rolling walking mechanism and the second rolling walking mechanism, the telescopic arm is respectively contacted with the first rolling walking mechanism and the second rolling walking mechanism to form rolling friction, so that frictional resistance is reduced, and the purpose of protecting the insulation arm support to keep good insulation performance all the time is achieved.
