Intelligent scraper conveyor and monitoring system thereof

Abstract

The invention discloses an intelligent scraper conveyor and a monitoring system thereof. The monitoring system is characterized in that a machine head controller, a machine tail controller, a machine head frequency converter and a machine tail frequency converter are connected through a bus, the machine head controller and the machine tail controller are respectively and electrically connected with a cooling water state information detection device, a speed reducer state information detection device, a bearing state information detection device and a motor state information detection device, and the interiors of the machine head controller and the machine tail controller are respectively provided with a fault diagnosis module and a chain speed adjusting module. The intelligent scraper conveyor has the advantages that multiple fault information can be timely found, the speed of a chain can be adjusted according to the load change, and the fault probability of the chain is effectively reduced; the system structure is simple, and the centralized control is convenient.

Description

technical field [0001] The invention relates to the technical field of scraper conveyors, in particular to an intelligent scraper conveyor and a monitoring system thereof. Background technique [0002] In the operation of mechanized coal mining, scraper conveyor, as a working face conveying equipment, is one of the core equipment of mechanized coal mining in coal mines. It is used in conjunction with coal mining equipment and support equipment to achieve efficient coal output. The scraper conveyor is pulled by a scraper chain, and the conveyor that transports bulk materials in the tank is connected with the hydraulic support through the pulling mechanism, and moves with the hydraulic support driven by the pulling mechanism. [0003] Since the operation reliability of the scraper conveyor directly affects the continuity and safety of coal mining at the working face, the corresponding monitoring system is generally configured for the scraper conveyor so that the technology can...

AI Technical Summary

Problems solved by technology

[0003]Because the operation reliability of the scraper conveyor directly affects the continuity and safety of coal mining in the working face, the corresponding monitoring system is generally configured for the scraper conveyor , so that the technology can find problems in the operation of the scraper conveyor. The existing monitoring system for the scraper conveyor generally focuses on the acquisition of various on-site status information and the identification of alarms and shutdowns, and the functions are relatively single. , when the alarm or shutdown occurs, the on-site personnel will carry out inspection and maintenance, and replace the corresponding parts

[0004] Due to the complex operating environment of the scraper conveyor, changing working conditions, and frequent unbalanced loads, the service life of many components is relatively limited. For example, many faults of the scraper conveyor are related to the chain. Although the existing monitoring system It is possible to detect the failure of the chain in time, but it is difficult to effectively reduce the probability of failure of the scraper conveyor

In addition, the current monitoring system has many discrete devices, the overall scheme is relatively complicated, and it is difficult to centrally control
