随着煤矿高产高效技术的发展和采煤机功率的不断增大,对采煤机牵引部提出了越来越高的要求。在传统采煤机加载技术的基础上提出双电牵引部同步加载方案,可同时完成对采煤机左右电牵引部的同步加载试验,极大地提高了试验效率、解决了电牵引采煤机变濒控制系统与双行走部试验的匹配试验技术,具有巨大的经济价值。 With the development of high-yield and high-efficiency coal mines and the continuous increase of shearer power, higher and higher requirements are placed on the shearer of the shearer. On the basis of the traditional shearer loading technology, the synchronous loading scheme of the electric double-traction unit is put forward, which can simultaneously carry out the synchronous loading test on the left and right electric traction parts of the shearer, greatly improve the test efficiency, and solve the problems that the electric shearer becomes dying Control system and dual-walk test of the matching test technology, with great economic value.
