FIELD: machine building. ^ SUBSTANCE: device to fix a cable in areas of coupling connection of pipes comprises a casing with an inner surface covering the pipe at the angle of less than 180, with slots arranged in it, one of which, the longitudinal one, is designed to lay the cable, and the other one - for installation onto the coupling of the well tubing strings. On one of the casing side walls there are yokes installed hingedly with fastening units. On the outer surface of one side wall of the casing there is a protective element - a ledge- arranged between hinged units of yokes fixation, and at the opposite wall between responsive slots there is a protective element - a protective rib. On the same side wall, perpendicularly to the protective rib, there are two protective elements - ribs arranged. At the same time on the side wall, at the edges of the responsive slots, there are protective elements - fixators, which prevent unscrewing of eye bolts. ^ EFFECT: improved operational properties of the device for fixation of the cable in areas of coupling connection of well tubing strings and higher reliability of fixation, protection against damages during round trip operations and operation in wells with higher angles of inclination and curvature. ^ 5 dwg |
