输送带接头动态耐久性能实验台研究设计
[Abstract]:According to the content of MT668-2008 National Coal Industry Standard, this paper simulates the actual loading of conveyor belt, and studies and designs the dynamic durability test platform of conveyor belt joint. This experimental platform can effectively determine the quality of conveyor belt joint and reduce the occurrence of fracture accident of conveyor belt joint. Therefore, its application has become more and more common. In this paper, the working principle and characteristics of belt conveyor are discussed in detail. According to its working principle and the specific requirements of experimental equipment, the executive device of the experimental platform is studied and designed, the experimental parameters are determined, and the concrete experimental scheme is put forward. The technology of conveyor belt and conveyor belt joint is discussed, and the dynamic durability of conveyor belt is analyzed. A hydraulic control system is designed. The system takes the electro-hydraulic proportional valve as the core, which can realize the control of the oil pressure of the system, so as to control the expansion force of the hydraulic cylinder, so as to meet the requirements of the experimental tension of the conveyor belt. A synchronous hydraulic control system with proportional directional valve as the core is designed to maintain synchronization when the two hydraulic cylinders work, and all kinds of synchronous hydraulic control systems are studied and analyzed. The components of the hydraulic control system are selected and calculated, and the detailed calculation process of the parameters of the hydraulic cylinder is given in this paper. An electrical control system is designed, the program block diagram of automatic starting and normal parking of the experimental platform is given, and the detailed control scheme of the normal operation of the experimental platform is put forward, and the belt speed and maximum load of the tested conveyor belt are put forward. The minimum load and experimental period are effectively controlled. Finally, through the integration of the above executive device, hydraulic control system and electrical control system, the dynamic durability test platform of conveyor belt joint is established.
