Full-automatic hydraulic grab loading system and asphalt pavement maintenance vehicle including same

Abstract

The invention discloses a full-automatic hydraulic grab loading system and an asphalt pavement maintenance vehicle including the same, belonging to the field of road maintenance equipment. The full-automatic hydraulic grab loading system comprises a fixed base, a slewing bearing, a slewing vertical pillar, an amplitude-variable hydraulic cylinder, a stretchable suspension arm, a two-section hydraulic cylinder, a rotating hydraulic cylinder, a grab fixing seat, grabs, a grab hydraulic cylinder and a grab support seat. According to the full-automatic hydraulic grab loading system, the precise positioning, automatic grabbing, slewing feeding and precise unloading of asphalt mixed materials in any region of stretching and turning radii of the suspension arm can be realized; 160-degree rotation operation of the system is realized by virtue of the slewing bearing, the stretching and the folding of the suspension arm are realized by virtue of the hydraulic cylinder, the slewing and the stretching of the grab are realized by virtue of the rotating hydraulic cylinder, and the automatic grabbing and unloading of the asphalt mixed materials are realized by virtue of the grab hydraulic cylinder; by utilizing a three-section suspension arm, the stretching under the driving of the two-section hydraulic cylinder is realized, and 75-degree folding under the action of the amplitude-variable hydraulic cylinder is realized; and the grabs are symmetrically arranged, so that the 360-degree rotation operation under the driving of the rotating hydraulic cylinder is realized.

Description

technical field [0001] The invention relates to a fully automatic hydraulic grab feeding system, in particular to a fully automatic hydraulic grab feeding system and an asphalt pavement maintenance vehicle, belonging to the field of road maintenance equipment. Background technique [0002] Asphalt pavement maintenance vehicles are mainly used to repair pits, cracks, wrapping, edge gnawing, pitting, peeling, looseness and many other diseases of asphalt pavement. Usually, there are asphalt mixture mixing silos, and the feeding mechanism is often used to realize asphalt mixing. Material loading operation. [0003] Most of the existing asphalt pavement maintenance vehicles are loaded manually or with the help of simple motors and wire ropes, which is time-consuming and labor-intensive; while the loading devices with a high degree of automation controlled by oil cylinders often require manual loading, and the loading range is small, and The material turning mechanism has defects...

AI Technical Summary

Problems solved by technology

The fully automatic hydraulic grab feeding system is fixed on the asphalt pavement maintenance vehicle, which can realize the precise positioning, automatic grabbing, rotary feeding and precise unloading of the asphalt mixture in any area of ​​the boom telescopic gyration radius, which solves the problem of asphalt on the market. Pavement maintenance vehicles are loaded manually or with the help of simple motors and wire ropes, which is a time-consuming and labor-intensive problem
