AI Technical Summary

Technical Problem

Existing cleaning and maintenance vehicles have limited range when sweeping roads and cannot adjust the cleaning height and length according to the actual situation, resulting in poor cleaning effect and low practicality.

Method used

A roadbed maintenance device was designed, which adjusts the height of the fixed frame by an electric telescopic rod, adjusts the distance of the sweeping disc by a hydraulic cylinder, drives the sweeping structure to rotate by an electric turntable, and is equipped with a spraying system and a shock absorption device to achieve multi-angle cleaning and dust prevention functions.

Benefits of technology

It enables comprehensive cleaning of roads with different slopes and widths, increases the cleaning range and effectiveness, reduces dust, and improves the stability and service life of the robotic arm.

Abstract

This utility model discloses a highway subgrade maintenance device, including a mounting plate. An electric telescopic rod is symmetrically fixedly connected to the top of the mounting plate. A fixed frame is fixedly connected to the top of the electric telescopic rod. A hydraulic cylinder is symmetrically fixedly connected to one side of the fixed frame. Rotating blocks are symmetrically arranged at both ends of the fixed frame. A connecting rod is fixedly connected to one side of each rotating block. An electric turntable is rotatably connected to one end of the connecting rod. A support plate is fixedly connected to one side of the electric turntable. Liquid inside the water tank is pumped into the spray pipe via a water pump and a gooseneck pipe, and then sprayed onto both ends of the brush through nozzles, increasing the cleaning effect of the brush and preventing dust from polluting the external environment. A sleeve and a sliding rod are connected to the fixed frame and the connecting rod via ear plates. During use, a spring drives the sliding rod to slide inside the sleeve, damping and buffering the vibration generated by the robotic arm, increasing the stability of the robotic arm, reducing collisions between structures, and increasing the service life of the robotic arm.
