The utility model relates to a line shaped green laser width measuring instrument, which consists of a green line shaped laser, an imaging lens, an area array CCD, a gigabit network communication device and a computer. The utility model is characterized in that the green line shaped laser and the imaging lens are parallelly arranged on the upside of the to-be-measured object; the focusing surface of the imaging lens is corresponding to the projection area of the line shaped laser emitter; the output of the imaging lens is inputted into the area array CCD, while the output of the area array CCD is connected with the computer via the gigabit network communication device and a gigabit network wire. The utility model has the beneficial effects that: 1. timely online measurement of the width of medium plates and steel stripes can be effectively realized with higher measuring accuracy and stronger working stability; 2. the structure is simple and the use and installation are convenient; 3. the laser emitting and the image receiving are both arranged on the upside of the measured object together, thus the maintenance is easy to be carried out.
Description
Technical field
The utility model belongs to a kind of thick steel of steel plant that is used for and pulls width, and the measurement mechanism of hot rolled strip width is a kind of linear green laser width gage specifically.
Background technology
At present, pull steel band rolling line, particularly big section steel works Heavy Plate Production line, have very big difficulty always for the online width detection of steel plate at the field of metallurgy steel.In industrial measurement and control, width measure mostly adopts ordinary light source in conjunction with various photoelectric sensors or camera, camera.Because of measuring method and measuring position are subjected to too many restriction, adopt the above-mentioned existing method can't be in the in good time on-line measurement of the enterprising line width of many ad-hoc locations.Because of present Heavy Plate Production line mostly is built in five sixties of eighties of last century, production line is at that time considered less for continuous production again.This certain conditions also brings very big difficulty for modern measurement, adds that the steel plate thickness temperature contrast of each batch is too big, and the operating mode more complicated can present red or kermesinus as steel plate, and thin steel plate then can be a black.These differences of measuring object also make common photoelectricity and common survey method measure normally.
Summary of the invention
The purpose of this utility model provides a kind of linear green laser width gage that can carry out online detection in the place that the technology in many past can't be measured, to overcome the deficiency that prior art exists.
To achieve these goals, the utility model is made of the linear laser instrument of green, imaging lens, area array CCD, kilomega network communicator and computing machine, be characterized in: the top that the linear laser instrument of green and imaging lens is set in parallel in testee, the focusing surface of imaging lens is corresponding with the projection in zone of linear laser transmitter, the output of imaging lens inputs in the area array CCD, and the output of area array CCD is connected with computing machine with the gigabit netting twine by the kilomega network communicator;
Linear laser instrument of above-mentioned green and imaging lens are installed in parallel on the support of top of testee;
Above-mentioned imaging lens, area array CCD and kilomega network communicator are two covers, and two imaging lens are installed in parallel in the two ends of green linear laser instrument respectively;
The front end of above-mentioned imaging lens also is equipped with the narrow-band-filter eyeglass.
The beneficial effects of the utility model are: 1, can effectively realize the width of cut deal or steel band is carried out in good time on-line measurement, the precision of detection is higher, and job stability is strong; It is 2, simple in structure, easy to install and use; 3, Laser emission and image are accepted to be easy to safeguard with the top of putting with testee.
