本文重点介绍了破碎理论和破碎机的发展历程与各类型优劣情况,进而对当前破碎机所存在的问题进行了一些构想,完成了一种新型破碎机的总体方案设计.着重针对铸铝生产线中的破碎机构进行设计,依次进行了电动机、减速机选型,并对主要零部件进行了结构设计、受力分析和强度校核.

This paper presents the design of a novel radius-variable-gripper (RVG) for use as end-effector of highvoltage hot-line cleaning robot (HVCR). A eight-bar linkage mechanism is proposed to obtain the aim of 1-dof acutuation. According to the shape of insulators, the dimension design and kinematic analysis of RVG have been carried out. The optimization is performed to locate the joint points of arm segments, on which the brushes are mounted, approximately on the position circles in the whole opening-and-closing process of RVG. The prototype has been given finally, and it is showed that RVG is feasible to this special application.

The 4 wheels drive mobile carrier is the mobile carrier of"the high voltage cleaning robot".Its task is to make "the high voltage cleaning robot" move flexibly in the crowd environment.According to the special mechanical design of the carrier,We invented diagonal moving,diagonal turning and used frictional wheel to stop the moving carrier. Finally we made the robot move flexibly.
