AI Technical Summary

Technical Problem

Existing highway maintenance guardrail cleaning equipment cannot replace the cleaning structure during the cleaning process, resulting in reduced cleaning effect, requiring multiple cleanings, and requiring machine downtime when replacing the cleaning structure, which prolongs working time and reduces work efficiency.

Method used

A guardrail cleaning device was designed, comprising a load-bearing hydraulic rod, an electric telescopic rod, a guide structure, a transmission structure, a limiting structure, and a cleaning structure. The device enables quick replacement and position adjustment of the cleaning roller brush by locking screws and nuts, allowing the cleaning structure to be replaced without stopping the machine.

Benefits of technology

This technology allows for the replacement of cleaning structures without stopping the machine during the cleaning process, improving work efficiency, reducing cleaning time, and maintaining cleaning effectiveness.

Abstract

The utility model discloses a guardrail cleaning device for road maintenance, which relates to the technical field of road maintenance and comprises a bearing hydraulic rod and an electric telescopic rod, the electric telescopic rod is mounted on the outer wall surface of the bearing hydraulic rod, a splash-proof sleeve is mounted on the outer end surface of the electric telescopic rod, and a guide structure is mounted in the splash-proof sleeve. A transmission structure is connected into the guide structure, a limiting structure is connected to the transmission structure, a cleaning structure is connected to the transmission structure, and a conveying structure is connected to the lower wall face of the bearing hydraulic rod. The road guardrail cleaning device has the advantages that after the first group of guide push rods finish cleaning, the first group of cleaning roller brushes are driven to retreat from the road guardrail body along the corresponding guide frames, the second group of guide push rods are synchronously started to execute cleaning operation, and an operator disassembles the retreated first group of cleaning roller brushes and stores the retreated first group of cleaning roller brushes in an old brush bin in the storage box; and then the two cleaning roller brushes are taken out from a new brush bin in the storage box to be replaced, and the operation is repeated.
