中小矿山的井口提升大多采用音响信号,即信号工发出的提升信号只能听到铃声。多水平提升的矿井,信号复杂,易出事故。根据一般矿山长期使用的一停、二、四上、三下的音响信号表示方法,要求井口信号做到: 1.按一下指令按钮,对应一组指示灯亮,按二、三、四下,对应二、三、四组指示灯亮。同时,每按一下,电铃响一次; 2.按动停止按钮,铃响灯灭; 3.要有水平指示; 4.结构简单,安全可靠,维修方便。灯光音响双重井口提升信号(附图)采用灯
Most small and medium-sized mine shaft lift to enhance the use of audio signals, that is, signals issued by the lifting signal can only hear the ring. Multi-level improvement of the mine, the signal is complex, easy to accident. According to the general mine long-term use of a stop, two, four, three under the acoustic signal that requires wellhead signal to do: 1. Click the command button, corresponding to a group of indicator light, according to two, three, four, corresponding Two, three, four groups of lights. At the same time, each time you press the bell rang once; 2. Press the stop button, the bell lights off; 3. Have a level indication; 4. Simple, safe, reliable, easy maintenance. Light and sound dual wellhead lift signal (with photos) with light
