Synchronization control system for multi-point driving scraper conveyor

Abstract

The invention discloses a multi-point driving scraper conveyor synchronism control system, and belongs to the technical field of fully-mechanized coal mining equipment control. The multi-point drive scraper conveyor synchronism control system comprises first-stage motors and a multi-stage motor set arranged between the two first-stage motors, the first-stage motors and all motors in the multi-stage motor set are provided with chain wheels and piezoelectric vibrators, and the piezoelectric vibrators, the first-stage motors and all motors in the multi-stage motor set are connected with a computer. When the scraper conveyor works, the piezoelectric vibrators send current intensity signals to the computer, and the computer judges the working state of the scraper conveyor according to the current intensity signals and controls all the motors in the first-stage motor and the multi-stage motor set to work. The synchronization control system of the multi-point driving scraper conveyor can realize graded start and stop of the scraper conveyor, reduce the total tension borne by the scraper chain, and improve the reliability of the system in the working process.

Description

technical field [0001] The invention relates to the technical field of fully mechanized mining equipment control, in particular to a synchronization control system of a multi-point driving scraper conveyor. Background technique [0002] At present, in the field of coal mining and transportation, the scraper conveyor has become an indispensable production equipment. The scraper conveyor runs for a long distance with a heavy load. If only motors are added at both ends, the overall tensile force will be too large, and the strength of the scraper chain will be too high, resulting in an increase in cost. The scraper conveyor relies on scraper chain transmission, and the chain drive has There is a certain hysteresis, and the safety of the long-distance working process cannot be guaranteed. [0003] Therefore, there is an urgent need for a better driving method to effectively solve the problems of long-distance working tension and scraper conveyor transmission lag. Contents of t...

[0002] At present, in the field of coal mining and transportation, the scraper conveyor has become an indispensable production equipment. The scraper conveyor runs for a long distance with a heavy load. If only motors are added at both ends, the overall tensile force will be too large, and the strength of the scraper chain will be too high, resulting in an increase in cost. The scraper conveyor relies on scraper chain transmission, and the chain drive has A certain hysteresis phenomenon, the safety of the long-distance working process cannot be guaranteed

[0003] Therefore, there is an urgent need for a better driving method to effectively solve the problems of long-distance working tension and scraper conveyor transmission lag.
