Protection device for hydraulic hinge steering rod of road roller

Abstract

The invention discloses a protection device for a hydraulic hinge steering rod of a road roller. The protection device structurally comprises a soil sticking-preventing device, the hydraulic hinge steering rod, wheels and an outer casing, wherein the soil sticking-preventing device is mechanically connected with the hydraulic hinge steering rod; the hydraulic hinge steering rod is arranged on theouter casing; the two wheels are symmetrically arranged at both sides of the bottom part of the outer casing. The protection device has the beneficial effects that a connecting rod is moved to drive arotary disc to rotate, so that the soil scraped from a steel wheel on an arc-shaped plate is scraped off by a scraping plate, thereby preventing the soil from sticking onto the steel wheel and falling onto the hydraulic hinge steering rod due to vibration of the equipment in the running process, and preventing the hydraulic hinge steering rod from being abraded due to sandy soil in the working process; because a wool roller is attached with the steel wheel, when the steel wheel is rotated, the lubricating powder on the wool roller is stuck onto the steel wheel, and the adhesion force betweenthe steel wheel and the soil is greatly reduced.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a protective device for a hydraulically articulated steering rod of a road roller. Background technique [0002] In order to obtain a stable subgrade during the construction of road construction projects, it is necessary to tamp the road surface to make the rolled layer produce permanent deformation and compactness. However, the current road rollers have the following defects: [0003] 1. When rolling semi-cohesive and cohesive soil, soil is easy to adhere to the steel wheel and the soil moves with the steel wheel. The accumulated soil increases the power consumption required by the steel wheel when it is working, and the thickened adhesion layer affects The smoothness of the road compaction. [0004] 2. The soil adhering to the steel wheel moves with the steel wheel and falls onto the hydraulic hinged steering rod due to the vibration generated by the operation of the equi...

AI Technical Summary

Problems solved by technology

[0003] 1. When rolling semi-cohesive and cohesive soil, soil is easy to adhere to the steel wheel and the soil moves with the steel wheel. The accumulated soil increases the power consumption of the steel wheel when it is working, and the thickness of the adhesion layer will affect the Evenness of road compaction

[0004] 2. The soil adhering to the steel wheel moves with the steel wheel, and falls to the hydraulic hinged steering rod due to the vibration generated by the operation of the equipment. The existence of sand and soil greatly increases the wear of the hydraulic hinged steering rod during the working process.
