Background technology
At present, domestic existing Hot Line does not have scroll measurement apparatus substantially.Quality examination and site operation personnel can only lead to
Naked eyes are crossed to judge coils of hot-rolled steel turriform, staggered floor.Cause it to steel roll tower shaped because experience difference is larger between operating personnel
Judgement differs greatly.It not only influences coils of hot-rolled steel quality judging, also influences the lifting of hot-rolled product quality.At the same time, with
The aggravation of market competition, client it is also proposed higher requirement to steel coil form quality amount.By effective means to coils of hot-rolled steel
The actual control situation of scroll is monitored, measures and seems more urgent.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of device for measuring coils of hot-rolled steel scroll, can be online to heat
The scroll of rolled steel coils is measured.
The technical solution adopted for the present invention to solve the technical problems is：A kind of dress for measuring coils of hot-rolled steel scroll is provided
Put, including rangefinder, for carrying out scanning single side, high speed acquisition distance measurement value and ranging height to the steel roll end on step rate；
Servomotor, for driving the rangefinder；Host computer, for highly drawing coil of strip tower according to the distance measurement value collected and ranging
Shape curve, and turriform curve is judged.
The rangefinder drives lower thereon move by the rotation of screw mandrel.
The rangefinder is laser range finder, and carrying out one side to the steel roll end on step rate using triangulation sweeps
Retouch.
The host computer extracts quantity at most close to each other using the collection value of the whole rangefinders of coil of strip as total sample
Point produce datum line, and by standard of datum line progress turriform curve judgement, wherein, the deviation of each point and datum line falls
The points of certain area account for this present interval turriform degree of percent body of sum.
The rangefinder and servomotor are located in measurement cabinet, and the measurement cabinet is made up of high temperature division board, and measurement cabinet
Interior to be provided with air cooling driers, the air cooling driers are used to cool to servomotor and rangefinder.
The rangefinder is also connected with cooling water pipeline.
Temperature sensor and alarm are additionally provided with the measurement cabinet, the temperature sensor is used for detection temperature, works as temperature
Degree is alarmed when exceeding threshold value by alarm.
Beneficial effect
As a result of above-mentioned technical scheme, the present invention compared with prior art, has the following advantages that and actively imitated
Really：The present invention carries out the detection of coil of strip scroll and up to standard using rangefinder, and the present invention uses turriform decision method complete with a coil of strip
The collection value of portion's laser range finder is total sample, extracts the most point close to each other of quantity and produces datum line, institute a little with base
The reflection staggered floor degree that the deviation of directrix can be quantified, this judgment principle is consistent with the determination methods of people, it is ensured that the standard of measurement
Exactness.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
Fig. 2 is turriform curve synoptic diagram in the embodiment of the present invention；
Fig. 3 is stadia surveying schematic diagram in the embodiment of the present invention.
Embodiment
With reference to specific embodiment, the present invention is expanded on further.It should be understood that these embodiments are merely to illustrate the present invention
Rather than limitation the scope of the present invention.In addition, it is to be understood that after the content of the invention lectured has been read, people in the art
Member can make various changes or modifications to the present invention, and these equivalent form of values equally fall within the application appended claims and limited
Scope.
Embodiments of the present invention are related to a kind of device for measuring coils of hot-rolled steel scroll, as shown in figure 1, including rangefinder,
For carrying out scanning single side, high speed acquisition distance measurement value and ranging height to the steel roll end on step rate；Servomotor, for driving
Move the rangefinder；Host computer, for highly drawing steel roll tower shaped curve according to the distance measurement value collected and ranging, and to turriform
Curve is judged.The present invention can be connected by Ethernet with main line system, judge coil of strip information in place, and automatic start is measured,
And result of determination is issued into main line computer system, coil of strip measurement data and result of determination are stored in database, can pass through coil of strip
Number carry out the inquiry of historical data.
Reference operation work of the present invention, with reference to steel rolling index decision algorithm, generates turriform curve to the decision method of turriform
Decision method.It extracts quantity at most close to each other using the collection value of the whole laser range finders of coil of strip as total sample
Point produce datum line, institute a little and datum line deviation can quantitatively reflection staggered floor degree, the judgement of this judgment principle and people
Method is consistent.The points that each point and turriform datum line deviation fall in certain area account for the percentage of sum, and to may be embodied in this interval
Turriform degree, this has used for reference the hit rate algorithm of steel rolling.Turriform is quantitatively judged according to above method, meets actual feelings
Condition, and using hit rate as Judging index, database is together stored in coil of strip information.
The present invention drives laser range finder to move up and down by the rotation of screw mandrel, it is desirable to which stadia surveying process is steady, hold
Row mechanism rotary inertia is small, starts and stops rapidly, operating steadily, servo and high speed acquisition screw mandrel encoder values are controlled by PLC
, and stadia surveying value (Xn) (Yn).To meet the real-time, reliability, required precision of measurement apparatus, while considering system collection
Into simplify, present embodiment selection SIEMENS PLC and servo controller, servomotor.As shown in Fig. 2 it is every to detect coil of strip
The coordinate (Xn, Yn) of layer end points, with regard to turriform curve can be drawn.It uses laser range finder and leading screw to build two-dimensional detection system
System, leading screw drives rangefinder to move up and down, and leading screw encoder values are as Yn, and the value that laser range finder is detected at Yn is Xn.
The rangefinder uses laser range finder, and carrying out one side to the steel roll end on step rate using triangulation sweeps
Retouch：Sensor sends beam of laser and is mapped on measured object surface during measurement, luminous point by image lenses to CCD image sensor,
As shown in Figure 3.
In order to avoid the heat radiation of hot coil of strip causes harm to filed detection system, the rangefinder and servomotor are located at
