[Abstract]:The shearer is one of the main equipments of mechanized and modern coal mining face, which takes the role of falling coal and loading coal. In order to ensure the high efficiency and safety operation of the shearer, it is necessary to carry out type inspection and factory inspection in the development and production of the shearer, and the main performance of the shearer needs to be tested after the overhaul in the process of use. It is of great practical significance to develop a set of testing instruments for the detection and evaluation of main performance parameters of shearer, which is of great practical significance for ensuring the safe and reliable operation of shearer. According to the main fault form and fault location of shearer, according to various test requirements of shearer in the overhaul specification of drum shearer, the voltage, current and temperature of motor, rotating speed of drum, noise of empty operation of shearer are determined in this paper. Bearing temperature, vibration, oil pool temperature of cutting part are the main parameters to be detected by automatic detector of shearer, and all kinds of parameter testing methods are determined according to shearer test standard. Combining with virtual instrument technology, sensor technology, signal analysis and processing technology and computer technology, an automatic measuring instrument for shearer performance based on PXI bus is developed in this paper. The hardware system of the instrument is constructed, which is composed of sensor, conditioning circuit, data acquisition device and display. The software system of the instrument is designed and developed on the platform of graphic programming language LabVIEW2011. The functions of data acquisition, analysis, processing, storage, result display, historical data query and so on are realized during overhaul or various tests of shearer. In this paper, the experimental platform of automatic performance detector of shearer is built, and the static characteristic of automatic detector is analyzed. The user login, parameter input, noise detection, speed detection, motor detection, temperature detection and vibration detection are analyzed. The main functions of user management, help and exit modules are verified. The experimental results show that the system has good static characteristics, the overall operation is good, each detection module can achieve the corresponding functional requirements, the instrument can meet the requirements of the shearer detection.
