FIELD: electricity. ^ SUBSTANCE: protector for protection and fixation of a power cable on a coupling of a lifting pipe comprises a solid body with a longitudinal slot of alternating profile for installation of an electric motor power supply cable and an additional lengthy element, besides, the body is equipped with yokes, which are fixed on hinged joints and have facilities of fixation to the body, besides, side parts of the body are arranged in the form of shelves, the inner diameter of walls of which is equal to the external diameter of lifting pipes, the body has grooves for installation onto the lifting pipe coupling, one of shelves is equipped for fixation of yokes with two axes approached to the side wall of the longitudinal slot for a power and an additional lengthy element, and the other shelf is equipped with a rib parallel to the slot bottom, and protruding beyond dimensions of the device for fixation of yokes to the body in the assembled position, and the specified yokes have thickness below the difference of external radii of the coupling and the lifting pipe, which are arranged as capable of elastic deformation as the protector is installed onto the coupling, and embrace the lifting pipe by an angle of more than 180. At the inner side of the solid body between its side parts, adjoining a shelf with a rib, there is an additional longitudinal slot for arrangement of a lengthy element in it in parallel with the electric motor power supply cable. The lengthy element is arranged in the form of a geophysical cable or a control cable. ^ EFFECT: provision of reliable protection and fixation of power and additional cables, in particular, a geophysical cable or a control cable on a coupling of lifting pipes, and facilitation and simplification of assembly. ^ 5 dwg |
