 cocioiii from rtujKoro carrying element-; and i (rope), for example, from metal (C01C) kamach.

One pa each K) a set of conical vgu; kj 4, diameter of holes of the coranes. X is provided with a gap, compensating for the bowing of the borehole. On the end surface of the sleeves 4 are placed the spacer segments of the split sleeve, each of which has a reciprocal innermost conical surface and a convex outer surface. The spacer segments of the liner 5 are fixed on the sleeves 4 with the weakness of these springs 6. The rope also contains a support device consisting of a cup 7 with a hole in its bottom, an elastic compensator, made in the form of a dish-shaped outer 8 and onorny 1payb 9 with convex ends ( the figures depict two). 1 Speaking end of rope 1 is embedded in a shank, which is a sleeve C) with an external thread 11.

The Q sleeves dispense into the walls of the CKBa.kHHbi, as shown in FIG. 2. Then a cKpeiiepHbm block (not shown) is attached to the installed anchor.

The elongated ends of the gpayb 9 reduce the bias, overload, and the elastic compensator 8. When the scraper moves away from the anchor and returns its position to the coaxial with the wellbore position, the elastic compensator 8 (spring cloth) prevents loosening ;; (T1bki e.che.menta 1, save spreading of the sleeves 5 in the wells of the well.

To remove the anchor, the scraper unit is removed from the bushing 10 from the bushing, screwing the nut 12 onto the shank, thus loosening the rope 1 g: removing the displacement.

This anchor device requires the HJHTh re0 task of securely fixing the scraper block when scraping in mines, in permafrost conditions in the Kolyma and Chukotka regions, where not one of the known anchor designs has not been used due to low operational reliability.
