Abstract
The present invention provides a kind of blast furnace Control System of Hoisting Feeder to saunter the automatic protector of car index, comprises car protector of sauntering, described in saunter that car protector comprises position coder, volume raises frequency transformer and PLC; The pulse encoder interface that frequency transformer CUVC plate raised by described position coder with described volume is connected; described volume is raised frequency transformer CUVC plate output interface and is connected with described PLC input interface; increase car protector of sauntering by feeding cart unoperated position by being originally changed into full-automatic regulation by manual regulation; improve level of automation and the control accuracy of hoisting system, reduce hoisting system failure rate. Effectively solve feeding cart and cannot realize the problem automatically controlling band brake apparatus elasticity, avoid the problem that material loading generation fault causes blast furnace staying. Feeding cart can uninterruptedly carry out material loading continuously, and system tends towards stability, it is to increase the output of molten iron and the quality of a class iron, stabilizes conditions of blast furnace, further increases certain economic benefit.
Description
Technical field
The present invention relates to metallurgical technology field, particularly relate to a kind of blast furnace Control System of Hoisting Feeder and saunter the automatic protecting method of car index brake protection device.
Background technology
Original blast furnace hoisting system feeding cart is without car index securing system of sauntering, and in feeding process, volume is raised motor and can be pulled dolly up-downgoing according to the setting of frequency convertor system parameter, and dolly is parked in fixing position. But raising motor internal contracting brake device due to volume uses for some time to loosen, and often occurs band brake apparatus to embrace the problem of incessantly dolly, it is necessary to go process before contacting electrician on duty. This kind of situation not only can affect normally carrying out of material loading, and cannot carry out automatic control and adjustment, can not deal with problems, create very big hidden danger before fault occurs. Consider the instability of band-type brake system, the elasticity of band-type brake can only be regulated in the past with experience, excessively tightly cannot not draw dynamicly dolly, cross pine and embrace again incessantly dolly, thus there is production hidden danger.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the shortcoming of prior art, it is provided that a kind of level of automation and all higher volume of control accuracy are raised material loading and sauntered the automatic protector of car index.
In order to solve above technical problem, the present invention provides the automatic protecting method that a kind of blast furnace Control System of Hoisting Feeder saunters the automatic protector of car index, described automatic protector comprises car protector of sauntering, described in saunter car protector comprise position coder, volume raise frequency transformer and PLC; The pulse encoder interface that frequency transformer CUVC plate raised by described position coder with described volume is connected, described volume is raised frequency transformer CUVC plate output interface and is connected with described PLC input interface, increase car protector of sauntering by feeding cart unoperated position by being originally changed into full-automatic regulation by manual regulation, improve level of automation and the control accuracy of hoisting system, reduce hoisting system failure rate; It is characterized in that described automatic protecting method, consider that report brake system is unstable, often occur report lock excessively pine cause dolly to exceed formulating adding of the problem novelty that continues to slide in region and slip the car index symbol of band-type brake tightness (the car index that slips be used to show), raise displacement motor encoder according to volume and operationally calculate actual range with encoded radio when stopping, it is determined that mean distance and leave �� margin value of 0.3 meter after determine maximum protection value of stopping; By maximum protection value by PLC access control system; according to function of reporting to the police in supervisory system; when trolley travelling exceedes parking point; picture occurs car index warning of sauntering; and show and specifically exceed distance; by sauntering, car index makes corresponding adjustment automatically, it is possible to band-type brake elasticity is adjusted to best position.
The technical scheme that the present invention limits further is: described volume is raised frequency transformer CUVC plate and raised Frequency Converter Control end CPU by PROFIBUS-DP agreement and volume and be connected.
Further, described PLC system adopts Germany's Siemens S7-400 series module; CPU module model is: 6ES7417-4HT14-0AB0.
The invention has the beneficial effects as follows: after using invention, effectively solve feeding cart and cannot realize the problem automatically controlling band brake apparatus elasticity, avoid the problem that material loading generation fault causes blast furnace staying. Feeding cart can uninterruptedly carry out material loading continuously, and system tends towards stability, it is to increase the output of molten iron and the quality of a class iron, stabilizes conditions of blast furnace, further increases certain economic benefit.

Embodiment
Embodiment 1
A kind of blast furnace Control System of Hoisting Feeder that the present embodiment provides is sauntered the automatic protector of car index, and as shown in Figure 1: comprise car protector of sauntering, car protector of sauntering comprises position coder 5, volume raises frequency transformer 4 and PLC rack 1; Position coder 5 is connected with the pulse encoder interface of the CUVC plate that volume raises frequency transformer 4, and the CUVC plate output interface that volume raises frequency transformer 4 is connected with PLC rack 1 input interface.
The CUVC plate that volume raises frequency transformer 4 is raised frequency transformer 4 control end CPU2 by PROFIBUS-DP agreement and volume and is connected.
The CPU2 module model selected is 6ES7417-4HT14-0AB0. Position coder 5 model selected is RV158N-011K1R61N-01024S/N:453598
A kind of blast furnace Control System of Hoisting Feeder is sauntered car index automatic protecting method, first raises displacement motor encoder according to volume and operationally calculates actual range with encoded radio when stopping, it is determined that mean distance also leaves the margin value of 0.3 meter. Determine maximum protection value of stopping; By maximum protection value by PLC access control system. The current position of dolly measured by position coder, position point is transferred to PLC system by frequency transformer CUVC plate, when unoperated position exceedes set(ting)value, according to function of reporting to the police in supervisory system, monitored picture ejects reports to the police, and then manually goes on-the-spot adjustment band-type brake elasticity in time.
In addition to the implementation, the present invention can also have other enforcement modes. All employings are equal to replacement or the technical scheme of equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
