Embodiment Construction

[0025] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] like figure 1 As shown, the gamma dose rate instrument automatic rotation verification device of the present invention includes an instrument clip, an instrument tray, and also includes a bearing, a main support rod, a gear, a motor, a motor fixing plate, and a verification platform; N instrument clips are evenly distributed and fixed on the instrument tray On the top, the gear is fixed under the instrument panel and on the motor, and the main support rod is connected to the instrument tray through bearings; N≥2; preferably N=8;

[0027] The instrument clamp is a vise-type fixture, one end of which is fixedly connected to the instrument tray, and the other end is a movable slider connected to the screw, which controls the forward and backward of the instrument clamp through the screw;

[0028] The instrument ...

Abstract

The invention belongs to the technical field of radiation-measurement laboratory instrument calibration and relates to an automatic rotation calibrating device for [gamma] dosage rate meters. When assembling the automatic rotation calibrating device for [gamma] dosage rate meters, first, a motor fixing tray is welded on a main supporting rod; then a motor is assembled on the motor fixing tray; then an inner gear is fixed on the motor through pins; then a bearing is installed on the top of the main supporting rod; an external gear is sleeved on the main supporting rod; then a meter stray is assembled with the bearing; finally, the external gear is adjusted and is fixed on the meter tray through screws; the main supporting rod is welded on a calibrating platform; a meter clamp is added to the meter tray for relatively fixing components. When calibrating personnel use the portable automatic rotation calibrating device for [gamma] dosage rate meters, they only need to control the motor to perform equidistance displacement through computer terminals.

Description

technical field [0001] The invention belongs to the technical field of instrument verification in radiation metrology laboratories, and relates to an automatic rotating verification device for gamma dose rate meters. Background technique [0002] At present, when radiation metrology laboratories carry out verification work, the instrument needs to be fixed and the position of the instrument counting tube must coincide with the collimator positioning point. In the existing verification device, the part that fixes the meter is a suspended fixture, which can only fix one meter at a time, and after each meter is verified, the verification personnel need to enter the irradiation room to replace the meter to be tested, and re-align and align it. device, thus seriously affecting the work efficiency of the verification work. At the same time, personnel frequently enter the irradiation room, which greatly increases the risk of accidental exposure of personnel. [0003] Therefore, t...
