Multi-machine drive control system

Abstract

A multi-machine drive control system is characterized by comprising an input shaft coupling, a copper rotor assembly, a disk assembly, a speed control mechanism, an electric actuator, an output shaft,and a base bracket, wherein the input shaft coupling is connected to the copper rotor assembly; the copper rotor assembly matches the disk assembly; the speed control mechanism is mounted on the output shaft; the copper rotor assembly and the disk assembly are connected to the electric actuator; and the output shaft is mounted to the base bracket through a bearing assembly. The multi-machine drive control system has the advantages of solves the harmonic interference of a frequency converter in a underground coal mine humid environment, and solving the problem that a hydraulic coupler is poorin soft start effect, low in transmission efficiency, complex in structure and difficult to maintain. As a pure mechanical transmission product, the multi-machine drive control system is high in reliability, long in service life, free of maintenance, especially suitable for harsh environments in underground coal mines, improves production efficiency, and achieves the initial purpose of achieving safe, efficient, convenient operations and low operation requirements.

Description

technical field [0001] The invention relates to the field of a safe, efficient and intelligent control system used in the field of underground belt drive in the coal mine industry, and in particular to a multi-machine drive control system. Background technique [0002] With the development of coal production, the application of long-distance, large-capacity, and high-power belt conveyors is becoming more and more extensive. How to reasonably determine the driving mode of large-scale belt conveyors has become one of the key technologies for its popularization and application. . In order to reduce the dynamic tension of the conveyor belt when the motor is started, improve the stress condition of the conveyor belt and the whole machine, and protect the power grid from the impact of large starting current, it is required that the drive system of a large belt conveyor can provide adjustable, smooth and Shock starting torque. In the case of driving multiple motors, it is hoped t...

AI Technical Summary

Problems solved by technology

Frequency conversion speed regulation driving device can obtain better driving performance, controllable speed curve can be obtained in the process of starting and braking, and has better energy saving effect, but its price and maintenance cost are relatively high, which is harmful to the underground working environment and There are high requirements for heat dissipation conditions, and judging from the current technical situation, the power of explosion-proof frequency converters used in coal mines is not yet large enough, which limits the application of frequency converter speed control devices in coal mines

Compared with frequency converters, hydraulic couplings are more widely used, but the soft start effect is poor, and the transmission efficiency is low, the structure is complex, and maintenance is difficult; CST technology has soft start and multi-machine power balance adjustment functions, but the operation process is complicated. The professional quality requirements for coal miners are high, and the cost is high
