Embodiment Construction

[0017] The gamma ray collimation and positioning device of this patent application, as shown in the figure, consists of a directional collimator 5 , and the mobile platform 1 carries the directional collimator 5 . The orientation collimator 5 is fastened on the top of the bracket 21 standing upright on the mobile platform 1 by the clamping belt 20 . The bracket 21 is a rod body, and cooperates with other components to form a height adjustment mechanism of the orientation collimator 5 . In the height adjustment mechanism, the bracket 21 is guided and slid to be set in the tube tube 12, the tube tube 12 is welded and fixed vertically on the fixed plate 11, the tube tube 12 passes through the mobile platform 1, and the fixed plate 11 is parallel fixed on the mobile platform 1 by the hanging nail 15 Below, the upper part of the pipe tube 12 is radially pierced with positioning nails 8, and the bracket 21 is provided with a number of height-adjusting grooves 13 of equal unit length...

Abstract

A gamma ray collimation positioning device provided by the invention comprises a directional collimator, a mobile platform and a laser emitter, wherein the direction of a laser projection track is the same as the direction of a ray of the directional collimator, and the laser projection track is located on a longitudinal projection line of a ray axis. According to the technical scheme, the alignment adjustment operation efficiency of the radiation center of the collimator and the center of a detected area is greatly improved, and the adjustment operation is simple in process, easy to operate, time-saving, labor-saving and efficient.

Description

technical field [0001] This patent application relates to a collimator of radiation non-destructive testing equipment, in particular to a device for assisting the collimator to complete centering adjustment before flaw detection. Background technique [0002] Before the gamma ray non-destructive testing operation, it is necessary to select different types of gamma ray collimators according to different detection requirements. The collimator is made of shielding materials, and the radiation source rays pass through the collimator channel and project to the film detection area. , the emission direction and emission angle range of the radiation beam are limited by its emission window. [0003] The radiation source is sent from the source tube to the directional collimator as the radiation center. During the detection operation, the radiation center, the radiation collimator, and the center point of the measurement area must be adjusted to the same straight line to form a three-...
