The measuring device for the scale of the billet length of the billet casing machine comprises an encoder and a programmable logic controller, wherein the encoder is connected with the programmable logic controller, and the encoder is mounted on a pulling-straightening roller of the billet casing machine. According to the utility model, the encoder mounted on the pulling-straightening roller is used for counting, then the programmable logic controller is used for calculating the billet length, and accurate measurement to the scale of the billet length of the billet casing machine is achieved by taking the advantage that pulling-straightening roller is driven by a hydro cylinder, so that the fluctuation is small. The measuring device provided by the utility model not only improves the measured scale accuracy, but also lowers the measured scale failure rate, reduces steel consumption, improves the production rate of a continuous caster, and prevents the billet from deviation.
Description
Technical field
The utility model relates to technical field of measuring, mainly is applicable to the long scale of steel billet casting machine base is measured.
Background technology
At present, domestic majority square billet scale system generally adopts contact type measurement wheel scale, and meter wheel promotes to be pressed against the square billet side through cylinder, and encoder revolves to count and measures square billet length on the square billet drive meter wheel.
There is following problems in the metering system of available technology adopting in practical application:
1. this scale mode receives external condition influence big, and measurement of factor is short when often causing square billet scale duration, has had a strong impact on the carrying out that produces;
2. the speed reducing ratio of meter wheel is little, and is influential to the precision of measuring;
3. meter wheel leans on cylinder pressure that meter wheel is pressed against on the square billet, and the gas pressure fluctuation is big, and frictional force drives the meter wheel rotation inadequately, and the side that meter wheel is pressed against square billet can press square billet partially, cause the square billet sideslip to bring a series of problems.
The utility model content
The utility model technical problem to be solved provides the long scale measuring system of a kind of steel billet casting machine base; It has the straightening roller that the encoder that is used to measure is arranged on the continuous-casting of steel billet machine; Utilize the straightening roller to adopt hydraulic oil cylinder driving; It is little to fluctuate, and the speed reducing ratio of straightening roller realizes the long scale of steel billet casting machine base is carried out characteristic of precise measurement much larger than the advantage of the speed reducing ratio of meter wheel.
For solving the problems of the technologies described above, the utility model provides a kind of steel billet casting machine base long scale measuring system, comprising: encoder, Programmable Logic Controller; Said encoder is connected with said Programmable Logic Controller, and said encoder is installed on the straightening roller of steel billet casting machine.
Improved technical scheme is that said Programmable Logic Controller is connected with the Programmable Logic Controller of cutting car.
Optimized technical scheme is that said encoder is a pulse coder.
The beneficial effect of the utility model is:
1. when the utility model carries out throwing production on the continuous-casting of steel billet machine; After the straightening machine starts; Through being installed in the voltage pulse signal of the pulse coder output on the straightening roller, utilize the straightening roller to adopt hydraulic oil cylinder driving, little advantage fluctuates; Realization is accurately measured the long scale of steel billet casting machine base, and calculates square billet length through Programmable Logic Controller.
2. when the utility model is connected with the Programmable Logic Controller of cutting car; Can gather, calculate, transmit, handle, take a sample, revise, show data through the Programmable Logic Controller of cutting car again; Thereby length variations that straightening velocity perturbation face causes is deposited accumulative total, arrived the cut lengths of setting after, cutting car sends shear signal; Thereby guaranteed the uniformity of long measurement of meter and scale control, improved the precision of measuring scale.
3. the utility model is installed encoder on the straightening roller, because the speed reducing ratio of straightening roller is much larger than the speed reducing ratio of meter wheel, thereby has further improved certainty of measurement.
4. the original system meter wheel leans on cylinder pressure that meter wheel is pressed against on the steel billet, and the gas pressure fluctuation is big, and frictional force drives the meter wheel rotation inadequately, and the straightening roller is to depress on steel billet through oil cylinder, and hydraulic pressure is big and stable counting is more accurate.
5. the original system meter wheel side that is pressed against steel billet can be pressed steel billet partially, and the straightening roller that the utility model adopts presses steel billet downwards, thereby has solved the problem of steel billet sideslip.
The utility model is counted through the encoder that is installed on the straightening roller, calculates steel billet length through Programmable Logic Controller again, utilizes the straightening roller to adopt hydraulic oil cylinder driving, and the little advantage that fluctuates realizes the long scale of steel billet casting machine base is accurately measured.The utility model has not only improved the measurement sizing accuracy, has reduced measurement scale fault rate, has reduced steel material consumption, has improved conticaster productivity ratio, and has avoided the steel billet sideslip.
Description of drawings
Fig. 1 is the connection sketch map of the utility model embodiment.
The specific embodiment
For further setting forth the utility model is to reach technological means and the effect that predetermined utility model purpose is taked; Below in conjunction with accompanying drawing and preferred embodiment, the specific embodiment and the operation principle of the long scale measurement mechanism of a kind of steel billet casting machine base that proposes according to the utility model is elaborated.
Can be known that by Fig. 1 encoder is installed on the straightening roller, Programmable Logic Controller is connected with encoder.For the selection of encoder, preferably adopt pulse coder.In the present embodiment, steel billet is a square billet.
In reality is produced; When on billet caster, carrying out throwing production; After the straightening machine starts,, utilize Programmable Logic Controller to gather voltage pulse signal again through being installed in the increment of rotation type pulse coder output voltage pulse signal on the straightening roller; After signals collecting finishes, in Programmable Logic Controller, calculate square billet length.When through EPA the square billet length signals being sent this device to the cutting car Programmable Logic Controller; Square billet length is carried out integrated treatment, sampling, correction, demonstration etc. as the scale control signal through the cutting car Programmable Logic Controller, thereby the length variations that straightening velocity perturbation face causes is deposited accumulative total; When reaching the cut lengths of setting; Cutting car sends shear signal, and at this moment, cutting car cuts square billet.
It should be noted last that; The above specific embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although with reference to instance the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of the utility model; And not breaking away from the spirit and the scope of the utility model technical scheme, it all should be encompassed in the middle of the claim scope of the utility model.
