Description

The object of the description is a portable installation for monitoring welded, cast and other metal products and using them for this purpose. Radioactive isotones with a low energy of gamma radiation.

Known radiographic and horned installations, equipped with remote control and mounted on a tripod; the lead chamber for an ammunition with radioactive irenaph, which is covered with a lid, does not provide for circular simultaneous matching of several parts, in addition to controlling the directed beam of gamma rays.

This disadvantage is eliminated in the radiographic installation described below by the fact that a mechanism is mounted inside the chamber to open and close the swivel cover, as well as simultaneously remove the amnule from the chamber and reverse its mixing. The mechanism for mixing the chamber lid and the ampoule is made in the form of a reversible direct current electric motor, vras, ayush, its gear and a screw kinematically associated with it, carrying the TdM adapter at one end, and two fingers at the opposite end, of which one finger in the curvilinear one is called on a drum coupled with a gear that opens and closes the cover, and the other finger controls the drive motor through microswitches.

In the drawing, a picture and a kinematic scheme of a manipulator of a radiographic unit.

The radiographic installation consists of three main parts: a container or a manipulator in which the ampoule with a radioactive preparation is placed; remote control with electrical equipment and a tripod.

Ampoule / with a radioactive drug, located in the inner cavity of the manipulator, is reliably isolated from the external environment by a lead sheath 2. The opening and closing of the manipulator cover 5, as well as the movement of the ampoule, is performed automatically with a remote control that can be set to any desired distance.

The indicated movement of the manipulator cover and the ampoule is produced from a driving electric motor 4 of direct current, installed inside the manipulator, through a gear transmission to the screw 5, which carries the ampoule with the radioactive preparation at one end and two fingers at the opposite end. The finger 5 with the outer end enters the groove of the drum 7, rotates it and by means of a gear connected with it opens and closes the lid 3 of the manipulator. The finger 8 by means of the microswitch 9 controls the operation of the drive motor and the movement of the ampoule / with the radioactive preparation. The opening and closing of the manipulator lid, as well as the interpelling ampoules, are fully synchronized.

Subject invention

Claims (2)

1. A portable radiography unit equipped with a remote control and a lead cover mounted on a tripod for an ampoule with a radioactive preparation, characterized in that, in addition to scanning the directional beam of gamma rays, also circular scanning of several parts simultaneously, inside the chamber mounted a mechanism for opening and closing the rotary cover, as well as the simultaneous removal of the ampoule from the chamber and its reverse movement. 2. The form of installation according to claim 1, characterized in that the mechanism for moving the chamber lid and the ampoule is made in the form of a reversible direct current electric motor rotating the gear and the screw kinematically connected to it, carrying an ampoule with a radioactive preparation at one end, and on. the opposite end is two fingers, of which one finger enters a curvilinear groove on the drum, coupled with a gear, which opens and closes the chamber lid, and the other finger controls the operation of the drive motor through microswitches.
