【摘要】：带式输送机输送带的作用是承载和运输物料，在运输过程中，由于物料的摩擦，容易造成输送带带面磨损甚至断裂等现象，因此，需要对输送带定时检修，更换，以保证运输物料的安全性。现有的换带方法及装置存在换带作业不连续、需要的人力物力较大、换带过程中安全隐患较大、矿山机械化程度较低等问题。因此需要一种高效率、高安全性的输送带换带装置来满足煤矿生产运输的需求。本文首先在分析带式输送机换带装置的现场工况与主要设计指标的基础上，根据不同运输情况带式输送机设计了不同的换带方案，对方案中的各个装置结构及组成进行了设计，并通过SOLIDWORKS三维建模软件，对装置的各装置进行模型的建立以及仿真装配。阐述了系统的换带的工艺流程。其次，对连续换带装置液压系统进行了设计，并对每个回路的工作流程进了分析；介绍了液压系统仿真软件AMESim，利用其对液压回路进行了模型建立，经过仿真分析得出仿真结果，，分别针对各个回路的仿真结果进行了分析，验证了液压系统运行的可行性。并对装置的夹带夹带性能、同步性能、驱动-张紧配合性能等关键技术进行了研究。最后，对连续换带装置工作现场进行了实验研究，实验结果表明，该装置具有很高性能可靠性，可以满足煤矿更换输送带工作，保证了煤矿的高效安全生产。
[Abstract]:The function of belt conveyor is to carry and transport materials. In the process of transportation, it is easy to cause wear and tear of belt surface due to the friction of material. Therefore, it is necessary to overhaul and replace the conveyor belt regularly. To ensure the safety of transport materials. The existing belt changing methods and devices have some problems such as the discontinuity of belt changing operation, the large manpower and material resources needed, the large hidden danger of safety in the course of belt changing, and the low degree of mechanization of mines. Therefore, a kind of high-efficiency and high-safety belt changing device is needed to meet the demand of coal mine production and transportation. Firstly, on the basis of analyzing the working conditions and main design indexes of belt changing device of belt conveyor, different belt changing schemes are designed according to different transportation conditions, and the structure and composition of each device in the scheme are designed. And through the SOLIDWORKS 3D modeling software, the establishment of each device model and simulation assembly. The technological process of belt exchange is described. Secondly, the hydraulic system of the continuous belt changer is designed, and the working flow of each loop is analyzed, and the hydraulic system simulation software AMESimis is introduced, which is used to build the model of the hydraulic circuit, and the simulation results are obtained by simulation analysis. The simulation results of each loop are analyzed, and the feasibility of hydraulic system operation is verified. The key technologies of the device, such as entrainment performance, synchronization performance, drive-tensioning performance and so on, are studied. The experimental results show that the device has high performance and reliability, which can meet the needs of changing conveyor belt in coal mine and ensure the high efficiency and safety of coal mine production.
