Abstract
The utility model discloses a steel tapping system provided with a diffuse reflection optoelectronic switch. The steel tapping system comprises a control system, wherein the diffuse reflection optoelectronic switch is adopted as a detecting element of the control system, and is connected with the control system through a lead. According to the technical scheme of the steel tapping system, impacts of a steel pole on a reducer and a base can be reduced.
Description
Technical field
The utility model relates to a kind of test set, specifically, relates to a kind of tapping system that is provided with the electric switch that diffuses.
Background technology
The tandem rolling line 3# process furnace of Baogang put into operation in 2005, and after going into operation, the equipment operation is more steady.The tapping system is the process furnace important component part, is taking on the important task of tapping, the tapping system by Controlling System (adopt PLC mode), transmission system (a 72KW motor), two step-down gears, one have refrigerating function go out steel pole and go out steel socket to form.
As shown in Figure 1, be connected block diagram for Controlling System in prior art with the circuit of solid crystals tubular type approach switch.Solid crystals tubular type approach switch is the part of Controlling System as measuring element, and solid crystals tubular type approach switch, by the wire connection control system, sends detection signal to Controlling System.
As shown in Figure 2, be the fundamental diagram of solid crystals tubular type approach switch in prior art.Going out steel pole has former and later two stop bit, adopts the measuring element of solid crystals tubular type approach switch as former and later two stop bit signals.Tapping system use initial stage operation is more steady, but, along with the increase of frequency of utilization, goes out steel pole and move back and forth on tapping spout, due to friction, causes the gap of steel pole pulley and base tapping spout to become gradually greatly, while making out steel pole move, there will be and rocks.The initial stage of rocking is little owing to rocking, and does not affect tapping, and larger owing to changing the complete assembly expense, does not change out steel pole and tapping spout in the time of unless it is absolutely necessary.It is 15 ㎜ that solid crystals tubular type approach switch detects distance, when going out steel pole and stablize, can meet testing requirement.After going out steel pole appearance shake, or can't detect out the steel pole position, or approach switch is broken, and front limit position is near fire door.Solid crystals tubular type approach switch is apart from fire door 2m, and owing to being heated for a long time, approach switch is often malfunctioning, does not realize automatically stopping, and can not meet processing requirement.
Can't detect front stop bit, there will be steel pole directly to bump against on fixed pulley, cause step-down gear to rock, suppress the burning motor when serious; Can't detect rear stop bit, there will be steel pole to bump against on base, cause that firm banking is loosening, when serious, also can suppress the burning motor.Often need a tapping work commander operative employee tapping nearby.Stop bit before and after not having, damage equipment, need again to increase a labor force.
The utility model content
The technical problem that the utility model solves is to provide a kind of tapping system that is provided with the electric switch that diffuses, and can reduce the impact of tapping pole pair step-down gear and base.
Technical scheme is as follows:
A kind of tapping system that is provided with the electric switch that diffuses, comprise Controlling System, and the measuring element of described Controlling System adopts the electric switch that diffuses, and the described electric switch that diffuses connects described Controlling System by wire.
Further: the described electric switch that diffuses is arranged in front stop bit check point and rear stop bit check point, and described front stop bit check point is positioned at stop bit before steel pole, and described rear stop bit check point is positioned at the described stop bit after steel pole that goes out.
Further: the distance of described diffuse electric switch and fire door is 4 meters.
After using technical solutions of the utility model, the technique effect compared with prior art brought comprises:
1) reduce the impact of tapping pole pair step-down gear and base;
2) reduce the probability of motor burning, the work-ing life of improving motor;
3) reduce because of the spare part broken or high temperature damages;
4) reduce the time of casualty produced because changing spare part;
5) save the labor force.
The accompanying drawing explanation
Fig. 1 is that in prior art, Controlling System is connected block diagram with the circuit of solid crystals tubular type approach switch;
The fundamental diagram that Fig. 2 is solid crystals tubular type approach switch in prior art;
Fig. 3 is that in the present invention, Controlling System is connected block diagram with the circuit of the electric switch that diffuses;
Fig. 4 is the fundamental diagram of electric switch of diffusing in the present invention.
Embodiment
Phenomenon for going out when steel pole moves there will be shake, according to on-the-spot actual environment, change solid crystals tubular type approach switch into the electric switch that diffuses.
As shown in Figure 3, be connected block diagram for Controlling System in the present invention with the circuit of the electric switch that diffuses.The electric switch that diffuses, by the wire connection control system, sends detection signal to Controlling System.
Employing diffuses after electric switch, does not need the baffle plate of approach switch, directly usings the tamper of steel pole body as the electric switch that diffuses.The electric switch that diffuses is a kind of sensor that integrates projector and receptor, and when object to be detected being arranged through out-of-date, the light reflection of the q.s that object is launched the optoelectronic switch projector is to receptor, so optoelectronic switch has just produced switch signal.
The electric switch that diffuses adopts infrared detection; there is good return difference characteristic; even thereby detected object is shaken the output state that also can not affect driving mechanism among a small circle; thereby can make its protection in stable work area; simultaneously self-diagnosable system can also show and is subject to light state and problem workspace, to monitor at any time the work of optoelectronic switch.
As shown in Figure 4, be the fundamental diagram of the electric switch that diffuses in the present invention.The electric switch that diffuses is arranged in front stop bit check point and rear stop bit check point, and front stop bit check point is positioned at stop bit before steel pole, and rear stop bit check point is positioned at stop bit after steel pole.
At rear stop bit check point, adopt out the steel pole signal to appear as the program detection signal; It is the program check point that front stop bit check point adopts out the steel pole blackout.Such benefit is that the electric switch that makes to diffuse is increased to 4 meters apart from the fire door position by 2 meters, avoids thermal source to bake bad measuring element.
The electric switch that diffuses of front stop bit check point and rear stop bit check point adopts the electric switch PNP form (often opening) that diffuses, and so just can solve well the problem of the controlled plant shake that solid crystals tubular type approach switch can't resolve.
