Embodiment Construction

[0036] The present invention will be described below in conjunction with the accompanying drawings and embodiments.

[0037] Such as Figure 1 to Figure 11 As shown, a fully automatic hydraulic grab feeding system of the present invention includes a fixed base 1, a slewing support 2, a slewing column 3, a luffing hydraulic cylinder 4, a telescopic boom 5, a double-section hydraulic cylinder 6, a rotating hydraulic cylinder 7. Grab fixed seat 8, grab 9, grab hydraulic cylinder 10 and grab support 11.

[0038] In this embodiment, the fixed base 1 is connected to the sub-frame 12 through several bolts.

[0039] In order to provide a fully automatic hydraulic grab feeding system that can realize slewing operations, a slewing support 2 and a slewing column 3 are introduced. The slewing bearing 2 is a worm gear mechanism, including a hydraulic motor 2-1, a worm 2-2, a turbine outer ring 2-3, an inner ring 2-4, a base 2-5, an inner ring 2-4 and a base 2-5 are all connected to the ...

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...
