在现代化发展不断加快的过程中，我国国民经济飞速发展，人民生活水平不断提升。在这样的背景之下，我国各方面建设都有了显著的进步，其中科学技术的进步发展尤为显著。当前随着新型技术的不断研发，我国在各行各业中相关仪器设备也在不断地更新换代，这也为我国的发展带来了很大的方便。刮板输送机则是当前使用比较广泛的一类运输设备，该类设备主要用于选煤厂内的生产车间以及系统，在特大型煤矿选煤厂、露天矿场中的使用更是极为广泛。刮板输送机的使用很大程度上提高了选煤厂等的工作效率，同时也降低了员工的工作力度，因而国家也大力支持各厂积极引入刮板输送机。然而刮板输送机使用过程中也存在着很多的问题，其中最为重要的便是刮板输送机保护装置方面所存在的缺陷，保护装置的不完善很可能造成严重的安全事故，因而对于刮板输送机保护装置的改进十分有必要，以下就刮板输送机保护装置的改进方法进行深入的探讨分析。“,”in the process of accelerating the development of modernization, China's national economy is developing rapidly, and people's living standards are constantly improving. In this context, China has made remarkable progress in all aspects of construction, especially in the development of science and technology. At present, with the continuous development of new technology, the relevant instruments and equipment in all walks of life are constantly updated, which also brings great convenience for the development of our country. Scraper conveyor is a kind of transportation equipment which is widely used at present. This kind of equipment is mainly used in the production workshop and system of coal preparation plant, especially in large coal preparation plant and open pit. The use of scraper conveyor has greatly improved the efficiency of coal preparation plants, but also reduced the work of employees, so the state also strongly supports the introduction of scraper conveyor. However, there are many problems in the use of scraper conveyor, the most important of which is the defects in the protection device of scraper conveyor. The imperfect protection device may cause serious safety accidents, so it is necessary to improve the protection device of scraper conveyor, The improvement methods of scraper conveyor protection device are discussed and analyzed in depth
