Abstract


In this paper, structural design and finite element analysis of liner replacement manipulator on large-scale Ball Mill has been done based on Shenyang Heavy Machinery Ltd’s Large Ball Mill robot research, and strength check to structure of the manipulator has been carried out. This study content includes the following areas:(1) The design basis of the liner replacement manipulator has been analyzed and the key working parts of the robot, including chassis parts, liner part of the crawl, rotary platform, beam part, hydraulic parts, electrical control and so on, have been identified.(2) Taking MLH2000 mill as the research object, the liner replacement manipulator for it has been designed. The device design parameters, including hydraulic part of the various parameters, have been determined.(3) According to the design parameters, the overall structure of the robot has been designed by CAD. Three-dimensional machine model has established through software CATIA. Typical work posture of the manipulator has been obtained based on the whole working process of liner replacement. Dynamic simulation results show that MLH2000 liner replacement robot can grasp easily and hung liner quickly with reliable manner. It can rotate freely in the mill expansion and enter and exit the work place quickly. The structure is simple and reliable and easy to be manipulated.(4) Strength of the key parts on the liner replacement manipulator, including liner upgrade chain, outrigger wire rope, wire rope car operation panels, various types of hinge pin, the cylinder piston and rod, telescopic crane telescopic strength, horizontal beam Casing strength overlay, has been calculated. Finite element analysis of the whole machine has been done by using software ANSYS, the results show that the device can meet the requirement in practical work.(5) Finally, research work of this paper has been summarized.
