Abstract
Belt conveyors are the main transportation equipment for bulk materials such as coal port terminals. Through friction, power is transmitted. The friction force of the drive roller comes from the tension between the conveyor belt and the roller. The tension is achieved through the tensioning system. Through the design of the tensioning system, the design process of a typical general machinery can be mastered. The tension of the belt conveyor is achieved by tensioning the winch. This design is based on the analysis of the working principle, working environment and work characteristics of the tension winch, combined with the actual, after careful observation, the overall structure of the tension winch is designed, and the components are selected. Type, calculation and check. In order to develop more advanced tension winches, it has important research significance for the development prospects of tension winches. In today's era, tension winches are important equipment for mechanical processing in the machinery industry, so their research capabilities and development status have also contributed to the development of the entire industry of tension winches. At present, the inherent potential value of the tension winch industry in China remains to be tapped vigorously. Further research on the tension winch will bring important positive significance to the company and the entire machinery industry and society. While studying, it can also enable students to The overall ability is developed and exercised. The most important thing is that the overall design reflects this. First, we must let the now-graduated students lay the foundation for professional knowledge and thus enhance the knowledge they have learned so that they can do their job in the future. Second, they can allow them to look at issues with a development perspective in their projects, give full play to their innovative capabilities, and break through real-world problems. For the topic of tension winch design, its culvert has a wide range of knowledge and is extremely comprehensive. Students must rely on their excellent professional skills and vast knowledge, plus they must have a certain degree of computer graphics. ability. Therefore, students can actively think and delve into this design topic, so that students can gain the ability to analyze and solve problems, and thus can also accumulate work experience that will help the future.
This paper mainly describes the development history of hydraulic technology of tension winch and its current development situation at home and abroad, and briefly describes the development trend of hydraulic tension winches. At the same time, this paper briefly describes and analyzes the common hydraulic circuit of the hydraulic tension winch, designs and analyzes the small hydraulic tensioning system designed for the subject, and determines the required hydraulic components to complete the selection through further calculations. Use AutoCAD to draw schematics for the hydraulic system, work tank assembly, hydraulic layout, and tank parts drawings. Finally, the feasibility of this design was verified by checking.
