ABSTRACT:
A positioning and removal device for a checking means or a tool in a receiver installation, in a medium inaccessible to an operator. The device comprises a flexible guide track fixed to the receiver installation, a carriage movable over the track including a drive motor and a gear wheel, a loading sleeve fast to the carriage closed by a part and including a cam and a groove, a tool support unit provided with catches and an arrangement for hooking the support unit on a complementary arrangement borne by the installation. The forward movement of the carriage permits the opening of the hooking arrangement and hooking of the support unit onto the sleeve at the level of the groove by the catches, when the part is in out-of-service position. When the part is in service position on the sleeve, the forward movement of the carriage permits the transportation and hooking of the support unit of the tool to the receiver installation. The device is particularly useful in checking the tubes of a pressurized water nuclear reactor steam generator.
