The invention discloses a friction type elevator load abnormity monitoring method, which relates to the technical field of friction type elevators, and comprises the following steps: step 1, calculating a skip bucket theoretical seam current lower limit value, step 2, comparing an actual seam current value with the theoretical seam current lower limit value, and step 3, determining whether the actual seam current value is larger than the theoretical seam current lower limit value. If the actual seam current value is smaller than the theoretical seam current lower limit value, residual coal in the descending skip bucket is judged; and step 3, locking and loading the descending skip bucket, manually lifting the descending skip bucket to the unloading position again, and recovering normal loading of the descending skip bucket after confirming that the residual coal is completely unloaded. According to the method, only the actual coal loading quantity of the upward skip and the actual current value at the seam position need to be detected, the theoretical seam current lower limit value is calculated through the actual coal loading quantity, and the actual seam current value and the theoretical seam current lower limit value are compared, so that the load condition of the skip can be monitored, and whether the skip has residual coal or not is judged; and measures can be taken in advance to treat residual coal in the skip bucket, and secondary coal loading is prevented by descending the skip bucket to lock and load.

    本发明公开了一种摩擦式提升机载荷异常监视方法,涉及摩擦式提升机技术领域,包括以下步骤,步骤一,计算箕斗理论交逢电流下限值,步骤二,比较实际交逢电流值和理论交逢电流下限值的大小,如果实际交逢电流值小于理论交逢电流下限值,则判定下行箕斗余煤;步骤三,下行箕斗闭锁装载,手动将下行箕斗重新提升至卸载位置,确认余煤卸净后,下行箕斗恢复正常装载。本发明只需检测上行箕斗的实际装煤量以及在交逢位置时的实际电流值,通过实际装煤量计算理论交逢电流下限值,通过比较实际交逢电流值和理论交逢电流下限值的大小即可监视箕斗载荷情况,判断箕斗是否余煤,在箕斗余煤时可超前采取措施处理,通过下行箕斗闭锁装载来防止二次装煤。
