X-ray detection device with laser positioning function

Abstract

The invention provides an X-ray detection device with a laser positioning function. A laser positioner is mounted at a pipe head at the upper end of a circumferential X-ray emitter which is fixed on a lifting table through a ray emitter clamping mechanism by a semicircular structural pressing ring; fixed legs and movable legs at the upper ends of telescopic hinges are connected with the lifting table; fixed legs at the lower ends of the telescopic hinges are connected with a mounting base, and movable legs at the lower ends of the telescopic hinges are connected with a rolling shaft screw rod and a sliding rail on the mounting base; a connection rod mounted between the rolling shaft screw rod and the sliding rail is used for connecting the movable legs at the lower ends of the telescopic hinges; a mobile limiting block is mounted on the rolling shaft screw rod; a driving motor drives the rolling shaft screw rod to rotate through a gear; a steering wheel, a pushing handle, the driving motor and a control box are fixed on the mounting base. According to the X-ray detection device with a laser positioning function, the problems that a conventional circumferential X-ray detection device is heavy in structure and short in effective travel and the problems that annular ray beams are easily shaded and are hard to position are successfully solved; the X-ray detection efficiency and detection quality of the X-ray detection device are effectively improved.

Description

Technical field [0001] The invention relates to a device in the field of X-ray detection, in particular to an X-ray detection device with laser positioning function. Background technique [0002] X-ray inspection technology, as one of the five conventional non-destructive inspection technologies, is widely used in the inspection of internal defects in the welds of structural parts. Due to the small transillumination radiation angle during the working process of the directional X-ray machine, the detection efficiency is low. In the actual application process, for the longitudinal welds and girth welds of some large-diameter cylindrical components, the circumferential X-ray machine is generally used for 360° circular exposure inspection, which can greatly improve the inspection efficiency and reduce the labor intensity of the operators. . But at the same time, the circumferential exposure process requires a higher fixed position of the X-ray machine. Generally, the axis of the ci...
