MULTI CHANGER FOR CALIBRATION OF RADIATION DOSE RATE SURVEY METER

摘要

The present invention relates to a multi changer for the calibration of a radiation dose rate survey meter and, more specifically, to a multi changer for the calibration of a radiation dose rate survey meter, which remarkably reduces calibration time by simultaneously charging multiple radiation dose rate survey meters. The multi changer for the calibration of a radiation dose rate survey meter comprises: trays in which radiation dose rate survey meters are detachably loaded; two tray loading towers; a horizontal transfer part for a tray, which has a guide piece bent upward; a tray lifting device which successively loads the tray; a tray transfer device which transfers the tray to a calibration position; a first tray sensing unit which senses that the tray approaches the calibration position and transmits the sensing signal; a second tray sensing unit which senses that the loaded tray approaches an uppermost position in the tray loading towers and transmits the sensing signal; a third tray sensing unit which senses that the tray approaches a lowermost position in the tray loading towers and transmits the sensing signal; a fourth tray sensing unit which senses that the tray is completely loaded and senses the sensing signal; and a control part which controls the operation of the tray lifting device and the tray transfer device on the basis of the sensing signals received from the first, second, third, and fourth tray sensing units.;COPYRIGHT KIPO 2016
