Embodiment Construction

[0039] Now, the present invention is explained in detail in conjunction with the embodiments and the accompanying drawings.

[0040]The invention proposes a comprehensive efficiency evaluation and monitoring method of a main well hoisting system for lean production. The schematic flow chart of the inventive method is as figure 1 As shown, firstly, the planned lifting time and actual lifting time of the main well hoisting system are calculated according to the main well hoisting system evaluation cycle time, planned maintenance time, actual maintenance time, and failure time. Time and planned lifting time to calculate the operating rate of the main shaft hoisting system. According to the hoisting amount of the main well hoisting system per tick in the evaluation period, the actual hoisting amount of the main well hoisting system is obtained by accumulating; according to the actual hoisting time, the theoretical cycle period of the main well hoisting system and the theoretical ...

Abstract

The invention discloses a comprehensive efficiency evaluation and monitoring method of a main well hoisting system for lean production. This method first calculates the operating rate of the main well hoisting system by obtaining the planned hoisting time and the actual hoisting time in the evaluation period of the main well hoisting system. Then, the load rate of the main well hoisting system is calculated by obtaining the theoretical lifting amount and the actual lifting amount in the evaluation period of the main well hoisting system. Further, by obtaining the hoisting system of the main shaft to raise the gangue-containing rate of raw coal, the qualified rate of the hoisting system of the main shaft is calculated. Based on the operating rate, load rate and quality pass rate of the main well hoisting system obtained above, the comprehensive efficiency of the main well hoisting system is calculated and evaluated. Based on the above evaluation model, the overall efficiency of the main well hoisting system is monitored and the alarm is exceeded. The method of the invention scientifically evaluates the comprehensive efficiency of the main well hoisting system, and can control the comprehensive efficiency of the main well hoisting system within the required range, and is a practical and effective method.

Description

technical field [0001] The invention relates to the field of evaluating and improving the efficiency of production systems of coal mine enterprises, in particular to a method for evaluating and monitoring the comprehensive efficiency of a main shaft hoisting system for lean production. Background technique [0002] The main shaft hoisting system is the key equipment in the main coal flow transportation system of coal mine enterprises, and its hoisting efficiency plays a very important role in the comprehensive output efficiency of the main coal flow system of the coal mine. Studying the comprehensive efficiency evaluation and monitoring method of the main shaft hoisting system plays an important role in improving the overall efficiency of the production system of coal enterprises. [0003] The overall efficiency and actual lifting capacity of the main shaft hoisting system are affected by the failure time of the main shaft hoisting system, the maintenance time, the empty tim...
