The utility model relates to a protective monitoring device for stacking coal at the bottom of the main shaft. The existing monitoring device for coal heaping at the bottom of the well is prone to failure. Therefore, the monitoring device for coal heap protection at the bottom of main shaft includes acousto-optic alarm circuit and base frame, and also includes permanent magnet, magnetic induction switch and lever frame. The permanent magnet and magnetic induction switch are relatively arranged on the base frame. There is a magnetic shield between them. The lever frame includes a transverse axis. The two ends of the transverse axis can be rotatably fixed on the base frame through two bearings, and the middle section of the transverse axis is fixed separately. There are front and rear longitudinal rods, the front longitudinal rod extends between permanent magnet and magnetic induction switch, the rear longitudinal rod points downward, the magnetic shield plate is fixed on the front longitudinal rod, the lower end of the rear longitudinal rod is connected with an air plate, the magnetic induction switch is often opened in series to connect the acoustooptic alarm circuit, and the air plate is set at the windward part of the tunnel below the matching coal leak. The main shaft bottom coal heap protection monitoring device has the advantages of simple structure, suitable for working near the coal leak mouth with high humidity and dust, and suitable for major coal mines.
【技术实现步骤摘要】
主井底堆煤保护监测装置
本技术涉及一种主井底堆煤保护监测装置。
技术介绍
一般煤矿设计为主井提煤,当主井提升机在人为失误或突发条件下,即箕斗过装、溜煤口撒炭、箕斗门关不严等情况,都会造成井底堆煤过多,就会引起提升机尾绳扭转托起,拉坏主井提升机井筒设备设施、拉伤拉断提升机尾绳等恶劣事故。2012年04月04日公开的中国专利技术专利,公开了一种主井提升机井底堆煤监控装置,它是一种利用物位仪、煤位继电器、风速传感器对煤矿主井提升机井底堆煤高度、位置和井底撒煤漏斗堵塞情况分别实时监测,通过堆煤监控中心进行计算处理,进行报警和控制,防止煤矿主井提升机在人为失误或突发条件下而出现的井底堆煤过多引起的提升机尾绳扭转托起,拉坏主井提升机井筒设备设施、拉伤拉断提升机尾绳的安全监控技术措施。主井提升机井底堆煤高度、位置和井底撒煤漏斗堵塞情况三重采样,冗余化处理,分别实施报警和控制。但是由于主井漏煤眼处潮湿,风大、淋水大、煤粉粒多等,环境恶劣,风速传感器经常出故障。
