采煤机作为“三机一架”当中最重要的部分,在环境非常恶劣的工况下工作。当今各个煤矿满负荷运转、产量任务重,对采煤机的可靠性要求的越来越高。本文对采煤机机身连接结构方式进行了概述,并有针对性的对某种采煤机的机身连接结构设计做出了优化。 The shearer works as the most important part of the “Three Machines” and works under very harsh conditions. At present, all coal mines operate at full capacity with heavy production and heavy tasks, and the requirements for the reliability of shearer are getting higher and higher. This paper gives an overview of the connection structure of shearer fuselage, and optimizes the design of the fuselage connection structure of a shearer.
