Chain state monitoring and protecting system for scraper conveyor

Abstract

The invention discloses a chain state monitoring and protecting system for a scraper conveyor. The system is characterized by comprising a micro controller unit, a wireless measuring unit, an AC (Alternating Current) sampling unit, an analog quantity conditioning unit, a display unit, a communication unit, a keying unit, a switching value unit and a driving unit. According to the invention, a modularized system structure is adopted; all the units are combined into one organic integral body; a wireless measuring technology is adopted to more directly and accurately monitor an operating state of a chain; the state of the chain is dynamically regulated according to the load condition; after chain clamping and breaking accidents occur, fault protection is carried out by sending an alarm signal to an integral switch, and fault alarm is carried out; safety and stability of operation of the scraper conveyor are improved; and production safety of an underground coal mine is ensured.

Description

technical field [0001] The invention relates to a chain state monitoring and fault protection system of a scraper conveyor, which is especially suitable for monitoring and protecting the chain state of a high-power scraper conveyor in fully mechanized mining working faces in coal mines. Background technique [0002] The scraper conveyor is the main coal transportation equipment in the fully mechanized mining face, and its operation reliability directly affects the continuity and safety of coal mining in the working face. At the same time, with the continuous improvement of production efficiency, vigorously building fully mechanized mining faces with an annual output of 10 million tons has become the main development direction of mines in my country. This requires the continuous improvement of the installed and transport capacity of the scraper conveyor in the fully mechanized mining face, and at the same time puts forward higher requirements for the fault protection of the s...

Problems solved by technology

[0006] The purpose of the present invention is to provide a monitoring and protection system for the chain status of the scraper conveyor in the coal mine, which is used to solve the problem that the chain status of the scraper conveyor in the coal mine cannot be monitored accurately in real time, the chain cannot automatically adjust the operating status with the change of the load, and the chain cannot be automatically adjusted when the load changes. Problems such as failure to protect the chain in time after chain and broken chain faults
