Control loop of safe and nondestructive testing of strength conveyor belt

Abstract

The invention relates to a control loop of safe and nondestructive testing of a strength conveyor belt. Due to the facts that capacity value of the strength conveyor belt is increased and the strength conveyor belt is scratched and aging and other facts, the malfunctions that a steel wire rope core cracks and is rusted, a connector extends long and the like are caused, once the malfunctions occur, a major safety accident can be caused, production is stopped, losses of transport materials, damage of devices and huge economical losses and casualties can be caused, and safety production is seriously influenced. The control loop of the safe and nondestructive testing of the strength conveyor belt comprises an infrared emitter set, a switching circuit, a photovoltaic conversion circuit, an acquisition circuit and a controller, wherein the infrared emitter set, the switching circuit, the photovoltaic conversion circuit, the acquisition circuit and the controller are all connected with a power source, the controller is connected with an alarm circuit, and the controller is connected with an upper computer through an RS485 communication interface. The control loop of the safe and nondestructive testing of the strength conveyor belt is high in accuracy, safe, reliable, convenient to install and use, and capable of carrying out detection in an on-line and real-time mode and avoiding occurrence of major safety accidents, reduces the losses of the transport materials and the economical losses, and improves production efficiency.

Description

technical field [0001] The invention relates to a control circuit for safety and non-destructive detection of a powerful conveyor belt. Background technique [0002] At present, the strong conveyor belt has been widely used in mines, ports, power plants, steel plants, cement plants and other fields. During use, due to the increase in the load of the strong conveyor belt, scratches by obstacles and aging, the steel cord core Faults such as fracture, corrosion or joint elongation, once a fault occurs, will cause a major safety accident and stop production, loss of transported materials, damage to equipment, huge economic losses and casualties, seriously affecting safe production. Contents of the invention [0003] The technical problem solved by the invention is to provide a control circuit for the safety and non-destructive detection of the powerful conveyor belt with real-time detection and timely alarm. [0004] For solving above-mentioned technical problem, the technica...
