[Abstract]:Three-dimensional curing kiln palletizing machine, also called curing kiln stacker or palletizing car, is a special equipment for lifting and storing prefabricated components between roller conveyor line and maintenance kiln in the flexible production line of precast concrete components. Based on the industrial production of PC components in building industrialization, this paper makes a full investigation of the low production efficiency, high labor cost, high energy consumption, serious environmental pollution and long production cycle in the production of precast concrete components at home and abroad. The technical characteristics and development trend of stereoscopic maintenance equipment are deeply understood and analyzed. Based on the design method of lifting and transportation equipment, the general scheme is designed for the special operation requirements of maintenance kiln palletizing machine in PC flexible production line, and the design and selection of the main metal structure and parts of the palletizing machine are completed. The 3D solid model of palletizing machine is established by using Solidworks software in the design. The visual and parametric design is realized, and the design cycle is shortened. Based on the finite element theory, the strength, stiffness and mode of the main structure of the palletizing machine are analyzed by using the finite element ANSYS/Workbench analysis software, which verifies the scientific and reliability of the structural design of the palletizing machine. Compared with the traditional checking method, the stiffness, strength and stability of the main components are calculated accurately and intuitively. Finally, combined with the actual working conditions of the palletizing machine, a virtual prototype model is created by using ADAMS for the palletizing machine motion mechanism. Especially, the method of combining Bushing shaft sleeve force with CMD macro command is used to model the steel wire rope of lifting mechanism. Compared with the traditional modeling method, the difficulty of establishing ADAMS virtual prototype simulation model of palletizing machine is greatly reduced. The kinematics simulation analysis of the lifting scheme of the palletizing machine is carried out, and the kinematics parameters of the palletizing machine in the actual lifting operation are obtained, which provides the basis for the subsequent research on the optimization of the structure and the operation of the equipment. The palletizing machine designed in this paper is a special equipment for the production line of PC components. It can meet the requirements of the maintenance kiln access operation in the production of general PC products (beam, column, staircase, balcony, elevator well), and has strong versatility. In this paper, the design analysis and research of palletizing machine have engineering application value for the planning of flexible production line of PC component and the development of equipment.
