The rotation mechanism is made in the form of two reduction gears connected in a common housing, one of which is of a worm-type, and the other one is bevel-shaped. The latter is attached with the lower side of the bevel wheel to the grabbing device made in the form of a face plate, on which a bracket of an instrument frame with an instrument fixed on it is installed.EFFECT: reducing manual work, improving labour productivity, operating reliability and safety of service personnel at the installation and removal of instruments.4 cl, 5 dwg |
