Abstract

The invention provides a dry quenching hoister control device which comprises a PLC (programmable logic controller), a hoisting frequency conversion device, a walking frequency conversion device, a hoisting driving motor, a walking driving motor, a hoisting control relay and a walking control relay; the hoisting frequency conversion device and the walking frequency conversion device are both connected with a communication module of the PLC in a bus communication mode; the hoisting control relay is connected with an on-off input terminal of the hoisting frequency conversion device; the walking control relay is connected with an on-off input terminal of the hoisting frequency conversion device; and the hoisting control relay and the walking control relay are both connected with a DO (digital output) module of the PLC. The dry quenching hoister control device provided by the invention is simple in structure, can overcome defects of controlling independently through a communication mode or a terminal hardwired connection mode, and can stop reliably.

Description

technical field [0001] The invention relates to the field of control devices, in particular to a control device for a CDQ hoist. Background technique [0002] At present, there are two ways of signal exchange between the PLC controller of the CDQ hoist and each frequency conversion device: one is through communication, and the other is through terminal hard-wire connection. However, if the frequency conversion device is controlled solely by communication, if there is a communication problem, the PLC controller will completely lose control of the frequency conversion device if the frequency conversion device does not stop due to a communication failure; Without the possibility of damage to the sticky point of the control relay, and no matter how many control relays are used to control the start-stop and speed conversion of the frequency conversion device, in this case the PLC controller will still lose control of the corresponding frequency conversion device. [0003] How to...
