近年来,我国装载机已广泛用于矿山、建筑、水电、铁路、交通运输等各部门,装载机产品从小到大已自成系列。使用中进一步要求装载机除了装卸散松物料外,还要具有装卸原木、桶材、板材、箱装物资、废旧物料、起吊管子、挖掘、推土平整场地等多种装置。并能快速更换,以适应作业要求,达到一机多用、高效的目的。为此,须研制快速换斗装置。图1为几种常用的工作装置附具和快速换斗装置示意图。天津工程机械研究所和益都工程机械厂共同研制成功一种新型的机械式快速换斗装置,应用在ZL25装载机上(图2)。在设计该装置时,以原ZL25装载机工作装置为基础,不改变原机性能参数及工作装置 In recent years, China’s loaders have been widely used in mining, construction, utilities, railways, transportation and other departments, loader products from small to large self-contained series. In use, the loader is required to load and unload loose material in addition to loading and unloading loose material, and also have a variety of devices such as loading and unloading logs, barrels, plates, boxed materials, waste materials, lifting pipes, excavation and bulldozing formation. And can be quickly replaced to meet the operational requirements, to achieve a multi-purpose machine, efficient purpose. To this end, the need to develop fast bucket device. Figure 1 shows several commonly used work device attached and quick bucket device schematic. Tianjin Engineering Machinery Research Institute and Yidu Engineering Machinery Factory jointly developed a new type of mechanical quick changer device, used in the ZL25 loader (Figure 2). In the design of the device, based on the original ZL25 loader working device, do not change the original machine performance parameters and working device
