Background technology
The main detection flaw detection mode of current rail or i-beam frame is visual type or uses area array cameras shooting style to carry out, for example: the intelligent camera system of U.S.'s Cognex (COGNEX) company, what adopt is exactly the area array cameras detection mode of taking pictures, this mode principle is fairly simple, but there are two problems, the one, light source requirements is high, need uniform area source, cause complex structure, price is high, the 2nd, area array cameras is not suitable for the scanning work of continuous object, and need to pause wait or later stage are carried out Image Mosaics, affects work efficiency and accurate degree.Another kind of scheme is laser scanning methods, and take Switzerland ELAG company is representative, use a plurality of laser sensors to detect, but this scheme can only be found the defect of surface irregularity, for color, and extremely can not effectively the detecting of brightness.
Utility model content
The purpose of this utility model is to provide a kind of simple in structure, simple to operate, continuous bar shaped steel piece surface defect detection equipment that production efficiency is high, is especially applicable to rail surface defects checkout equipment.
The technical solution of the utility model is: a kind of rail surface defects checkout equipment, for rail surface defects, detect, this checkout equipment is by underframe, be threaded and be installed on the footing at four jiaos of places of underframe, rail gearing, overhead line-scan digital camera, side stand, overhead one word laser line generator forms, described side stand is fixedly mounted on underframe, in described side stand end face middle part, be vertically provided with vertical installing plate, middle part, side has been horizontally disposed with horizontal installing plate, described rail gearing is arranged on underframe, described rail gearing is by the motor being arranged on underframe, screw slide rails and motor control assembly form, the output terminal of motor is connected with screw slide rails one end, described overhead line-scan digital camera is arranged on the side stand top directly over rail gearing and rail, described overhead one word laser line generator is installed on described vertical installing plate, wherein said overhead line-scan digital camera and described overhead one word laser line generator are positioned on the face perpendicular with described rail length direction.
Preferred structure: side line-scan digital camera is housed on described side stand right side; On described horizontal installing plate, be also provided with side one word laser line generator, wherein said side line-scan digital camera and described side one word laser line generator are positioned on the face perpendicular with described rail length direction.
Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, rail surface defects detects convenient; Have simple in structurely, easy to maintenance, processing cost is low, production efficiency is high, is conducive to carry out the advantages such as large-scale promotion use.
