Description
Technical field
This utility model relates to metallurgical technology, particularly to steel rail straightening system.
Background technology
In beam-and-rail factory, a complete set of equipment of heavy rail finishing line straightening system is the horizontal straightener by 9 smoothing rolls and one
The cantilever vertical straightener of 7 smoothing rolls combines, and straightening system is vital equipment in Heavy-rail Production, the most indispensable
Few important step, the rail that only glacing flatness is qualified after aligning could be carried out to rail machining center as feedstock transportation
Rail scale processes the rail of high-quality.But there are 15 meters of left sides of afterbody during 100 meters of rail of aligning in heavy rail straightening machine
Right the most curved and strong trace in various degree, quality and the qualification rate of 100 meters of heavy rails can not be guaranteed, and production capacity is subject to significantly
Limit.
By observing, analyzing and study discovery, cause phenomenon and the main table of result that the most curved and strong trace of rail afterbody produces
The following aspects now:
1) it is observed that the speed of conveyor roller transport is the fastest, then the aligning speed of straightener is the fastest, rail tail swing
Amplitude and frequency the strongest；On the contrary, if the speed of conveyor roller transport is the slowest, the aligning speed of straightener is the slowest, swings
Amplitude and frequency are the least.Correspond in 100 meters of rail, when the normal production and transport speed of rail 1.8M/S enters straightener,
In straightening process, 15 meters of amplitudes swung of the afterbody of 100 meters of rail are the biggest and considerably more intense, and upper and lower jumbo swing results in
Rail afterbody is the most curved.Therefore, can only carry out straightening work with the low speed of 1.0M/S in producing at present, this allows for production efficiency
Ratio is relatively low.
2), near No. 1 smoothing roll of horizontal straightener inlet, No. 2 smoothing rolls, No. 3 smoothing roll motor loads also can be with steel
The amplitude of rail tail swing produces change, works long hours, and motor temperature raises fast, causes electrical machine insulation to reduce burn-out motor.
Being likely to cause flap-type braking resistor to blow damage, spare part expense increases, and fault rate increases simultaneously.
3), rail afterbody significantly vibrate and smoothing roll produce huge rubbing, cause roller to generate heat, smoothing roll glues iron filings and is pressed in steel
Formed on rail and rectify trace, mass defect occurs.The amount of reconditioning rail increases, and product qualified rate reduces.
Cannot meet, in terms of the running status and existing production status of equipment, the steel rail straightening quality that user is strict at all
Needs, this production capacity that seriously govern rail and product quality, simultaneously the biggest to the extent of damage of equipment.
Utility model content
The technical problems to be solved in the utility model is: provides a kind of steel rail straightening system, solves rail afterbody the most curved
Problem.
For solve the problems referred to above, the technical solution adopted in the utility model is: steel rail straightening system, including PLC,
Straightener, conveyor roller；PLC is connected with straightener, conveyor roller respectively；Straightener is provided with triggering grating,
Trigger grating to be connected with PLC.
Further, as in figure 2 it is shown, described straightener is provided with many smoothing rolls 3 and nearest from the entrance of straightener
Smoothing roll is No. 1 smoothing roll 301；The hard curved situation of afterbody is easily caused, it is assumed that a length of L of rail 4 according to actual, if conventional
Speed is not slowed down, and to easily cause the afterbody of H length the most curved, then trigger grating and should be arranged at No. 1 smoothing roll L-H of distance.
Further, described straightener is provided with iron filings blow device.
Further, described iron filings blow device is made up of three row's blowers, the most corresponding steel in position of each row's blower
The head of rail, left side, right side.
Concrete, described straightener includes horizontal straightener and vertical straightener.
Further, described horizontal straightener is positioned at the front of described vertical straightener.
The beneficial effects of the utility model are: by being provided with triggering grating on straightener, arrive when triggering Grating examinations
Rail afterbody easily produces the most curved when being partially into straightener, triggers grating and sends signal, PLC to PLC
Travelling speed and the straightener roll of straightener speed of conveyor roller can be adjusted, it is achieved low after receiving the signal triggering grating transmission
Speed aligning, eliminates the situation that rail afterbody is the most curved, improves the yield rate of rail, PLC after rail leaves straightener
Can recover travelling speed, therefore overall production efficiency can be more much higher than the efficiency transported only with low speed.On straightener
Arrange iron filings blow device, the viscous iron filings of smoothing roll can be blown away in time, it is to avoid iron filings are pressed on rail and form the feelings rectifying trace
Condition, the yield rate of rail is improved.
Accompanying drawing explanation
Fig. 1 is example structure schematic diagram；
Fig. 2 is to trigger grating scheme of installation；
Fig. 3 is iron filings blow device figures.
Label in figure: 1 for triggering grating, and 2 is conveyor roller, and 3 is smoothing roll, and 301 is No. 1 smoothing roll, and 4 is rail, and 5 are
Blower.
Detailed description of the invention
As shown in Figure 1, 2, the steel rail straightening system of embodiment includes PLC, straightener, conveyor roller, triggering light
Grid 1；Wherein, PLC is connected with straightener, conveyor roller, triggering grating 1 respectively；Trigger grating 1 and be arranged on straightener
On, easily produce whether the most curved part enters straightener for detecting rail 4 afterbody.Embodiment is applied to 100 meters of rail
During aligning produces, straightener is combined by the horizontal straightener of 9 smoothing rolls 3 and the cantilever vertical straightener of 7 smoothing rolls 3
Forming, horizontal straightener is positioned at the front of vertical straightener, and rail can first carry out level aligning and the most vertically align；Meanwhile,
Owing to the afterbody about 15 meters of 100 meters of rail 4 easily produces the most curved, triggering grating 1 is arranged on No. 1 smoothing roll of distance by embodiment
At 85 meters.
In production, when trigger grating 1 detect that 100 meters of rail afterbodys 15 meters are partially into straightener time, trigger grating 1 to
PLC sends signal, PLC after receiving and triggering the signal that grating 1 sends, PLC by conveyor roller 2 and
The speed of straightener roll of straightener is reduced to 1.0M/S by 1.8M/S, it is achieved low speed is aligned, after rail 4 leaves straightener, and will fortune
Defeated roller-way 2 travelling speed and straightener roll of straightener speed return to the speed of 1.8M/S, and the steel rail straightening speed of embodiment is average
Reaching and can arrive 1.6M/S, compared to the speed of tradition 1.0M/S, embodiment is effectively improved steel rail straightening yield, improves rail
Rolling production capacity.
As it is shown on figure 3, embodiment can also arrange iron filings blow device on straightener, iron filings blow device is blown by three rows
Airduct 5 forms, the position the most corresponding head of rail, left side, the right side of each row's blower 5.In straightening process, smoothing roll glues
Iron filings can be blown away in time, it is to avoid iron filings are pressed on rail and to form the situation rectifying trace.
The foregoing describing ultimate principle of the present utility model and main feature, the description of description simply illustrates this practicality
Novel principle, on the premise of without departing from this utility model spirit and scope, this utility model also has various change and changes
Enter, in the range of these changes and improvements both fall within claimed this utility model.
