摘要
本文以主井提升安全可靠、自动装载、提高效率为出发点，论述了钱家营煤矿主井提升定重装载安全系统的研制。系统以优质桥式传感器为信号转换设备，配接称重仪表和用于自动控制的可编程序控制器实现了定重装载显示和装载自动化，并通过提升电流与重量的比较实现对煤炭装载准确度的校验，同时避免主井提升二次装载事故的发生。该系统的研制成功，实现了煤矿井上、井下装载定量显示、安全显示与定量装载自动化，大大提高了煤矿主井提升效率，达到安全高效的目的。
This paper discussed the design of automatic loading and safety system for main shaft hoist scuttle in Qianjiaying Mining It taked the safe ty and credibility, automatic loading and high efficient producing as the basic purpose This system used the advanced bridge sensors as the signal transfer equipment, weighing instrument and PLC( Programable Logic Controlor ) for automatic control to achieve the fixed quantity display and automatic loading coal Comparing weight and current of hoist, this system can check and proof accuracy at same time At last it can try to avert accidents of repeating loading This system have many advantages, such as: fixed quantity loading and display on and under the ground , safety condition display and automatic loading whih fixed quantity, and so on It will take more efficiency and safety working on main shaft hoist scuttle, make the coalfields more safer and advanced
