Abstract
Przedmiotem zgłoszenia jest kotwa odspajająca posiadająca śrubę napędową (1) z zakończeniem kwadratowym (2) z jednej strony i z zakończeniem stożkowym (3) o kącie stożka 120° z drugiej strony, przy czym na śrubie napędowej (1) od strony zakończenia stożkowego (3) znajduje się tuleja sprężysto-rozprężna (4) z wewnętrznym podcięciem stożkowym pod kątem 30° do osi tulei sprężysto-rozprężnej (4) i nakręcona jest nakrętka stożkowa (5) o kącie tworzącej 30°. Kotwa charakteryzuje się tym, że do zakończenia stożkowego (3) śruby napędowej (1) zamocowany jest za pomocą dwóch kołków (6) stożkowy element podporowy (7) o kącie zewnętrznego stożka 130°.The subject of the application is a breakout anchor having a drive screw (1) with a square end (2) on one side and a conical end (3) with a cone angle of 120° on the other side, and on the drive screw (1) from the side of the conical end (3) there is a spring-expansion sleeve (4) with an internal conical undercut at an angle of 30° to the axis of the spring-expansion sleeve (4) and a conical nut (5) with an angle of 30° is screwed on. The anchor is characterized in that a conical support element (7) with an external cone angle of 130° is attached to the conical end (3) of the propeller (1) by means of two pins (6).
