Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and examples.
As shown in figure 1, the system for detecting and positioning the position of the billet on the furnace-entering roller way comprises a first laser grating detector 1, a guide rail moving rack 2, a laser range finder 3 and a second laser grating detector 4.
The first laser grating detector 1 is arranged outside the furnace entering roller way 6 and is opposite to the heating furnace and close to the square edge of the raw material, and is used for detecting whether the steel billet moves to the area of the heating furnace or not, sending an arrival signal to the roller way PLC, controlling the roller way motor frequency converter to operate in a speed reduction mode, and controlling the steel billet to move in a speed reduction mode;
the second laser grating detector 4 and the laser range finder 3 are arranged on the guide rail moving rack 2; the second laser grating detector 4 is used for detecting whether the steel billet reaches a preset target position, sending a reaching signal to the roller table PLC, controlling the roller table motor to stop moving, and further controlling the steel billet to stay at a specified position;
the laser range finder 3 is used for measuring the distance between the first laser grating detector 1 and the second laser grating detector 4 in real time and calculating whether the center position of the billet is consistent with the center line 7 of the heating furnace according to the distance parameter, so that the positioning and position detection in front of the billet furnace are realized;
the guide rail moving direction of the guide rail moving rack 2 is parallel to the furnace entering roller way 6, and the length of the guide rail moving rack is 1/2 of the effective width of the heating furnace; the guide rail moving rack 2 is arranged on the outer side of the furnace entering roller way 6 and is opposite to the furnace entering furnace door of the heating furnace;
