Abstract

The invention provides a scraper conveyor and its self-adaptive speed regulation method, which can obtain the real-time position value of the scraper conveyor when the shearer is running; read and record the running torque value of the frequency converter of the scraper conveyor, Through data analysis, the no-load torque value and full-load torque value of the scraper conveyor are obtained; through the relevant calculation of the frequency converter torque, speed, and shearer position, the current coal transportation volume of the scraper conveyor is simulated; according to The calculated coal volume is used to adjust the given speed of the scraper conveyor; the entire speed regulation process does not require the participation of any auxiliary sensors, and the reliability is higher.

Description

technical field

[0001] The invention belongs to the technical field of speed regulation control of scraper conveyors, and in particular relates to a scraper conveyor and an adaptive speed regulation method thereof. Background technique

[0002] In the fully mechanized coal mining face, the scraper conveyor is the first transportation equipment for coal mined by the shearer. It is widely used in coal mining, and every fully mechanized mining face needs to use this equipment.

[0003] Scraper conveyors generally use multiple drives, at least one drive motor at the head and tail of the scraper conveyor. The total power varies according to the working surface conditions. The small total power is 500kW, and the larger power The total power of the scraper conveyor reaches 4800kW.

[0004] With the development of frequency conversion technology, most scraper conveyors have adopted frequency conversion drive. The variable frequency drive prolongs the start-up acceleration process...
