提升容器是矿井煤炭生产过程中用于运输煤炭、设备及人员的设备，其安全运行直接关系到整煤矿生产的安全工作。在提升容器工作过程中，偏载是避免不了事情。一般情况下，轻微的偏载对提升容器的正常运行影响不大。但是，长期时间偏载会造成提升容器罐耳局部摩擦增大，影响罐耳使用寿命。严重的偏载会造成卡死甚至设备损坏、人员伤亡等更严重的安全事故。
发明内容
本发明目的在于提供一种矿井提升容器偏载危险报警方法，方法能够实时监控矿井提升容器偏载的程度，当严重偏载时发出警报。
为实现上述目的，本发明一种矿井提升容器偏载危险报警方法，包括以下步骤：
第一步、采集四个滚轮罐耳与轨道间的压力；
第二步、计算第一步中采集的四个压力偏差，包括绝对偏差和相对偏差；
第三步、在提升容器内实时显示压力偏差，包括绝对偏差和相对偏差；
第四步、当压力偏差大于第一门限时，通过语音报警；
第五步、当压力偏差大于第二门限时，启动提升容器安全处置程序。
本发明通过实时采集四个滚轮罐耳与轨道间的压力；通过压力偏差判断提升容器的偏载程度，根据提升容器的偏载程度，发出警报或者启动安全处置程序，能避免提升容器因严重偏载造成的危险运行，造成安全事故。工作人员根据提示，长期保持装载平衡，也能延长罐耳的使用寿命。
通过光学方法也能够测量提升容器因偏载造成的倾斜来判断提升容器的偏载情况。本发明与光学方法相比，具有直观的特点。
