以快速、高效为特点的履带式挖掘机广泛应用于土石方挖掘、装载施工。在挖掘机上改装抓料装置,可拓展其应用领域,实现一机双用。本文主要讲述履带式挖掘机改装为抓料机的液压系统结构设置及工作原理。1.改装方法将履带式挖掘机改装为抓料机的方法是先将挖掘机上的铲斗拆下,再将抓料装置安装在原铲斗的四连杆机构上。抓料装置上设有抓斗缸,以控制抓斗的张开与抱合。设有抓斗旋转马达,可控制抓斗360°
Crawler excavators featuring fast and efficient excavation are widely used in excavation and loading of earthwork. In the excavator modified grasping device, can expand its application areas, to achieve a machine dual-use. This article mainly describes the crawler excavator modified for the grasping machine hydraulic system structure settings and working principle. 1. Modification Method The crawler excavator is modified as a catcher method is to first remove the excavator bucket, and then grab the device installed in the original bucket four-bar linkage. A grapple cylinder is arranged on the grasping device to control the opening and the grasping of the grapple. Grab swing motor with 360 ° control
