Abstract

Przedmiotem zgłoszenia jest głowica kotwy rozprężnej, wykorzystywana jako element składowy kotwy w obudowie wyrobisk górniczych. Głowica kotwy rozprężnej utworzona jest z rozwieralnych szczęk połączonych z prętem, na który nasadzona jest nakrętka, przy czym rozwieralne szczęki są zaopatrzone na zewnętrznej powierzchni w poprzeczne zęby. Głowica kotwy rozprężnej charakteryzuje się tym, że jeden koniec pręta (6) ma postać widełek (5), do których zamocowane są obrotowe szczęki (1, 2) za pomocą sworznia (4), przy czym obrotowe szczęki (1, 2) złożone razem mają czołową zewnętrzną powierzchnię stożkową i oparte są o sprężynę (7) umieszczoną na pręcie (6), a podtrzymywaną z drugiej strony przez nakrętkę (9), przy czym obrotowe szczęki (1 i 2) mają na zewnętrznej powierzchni trójkątne zęby (3).The subject of the application is the expansion anchor head, used as a component of the anchor in the mining excavation housing. The expansion anchor head is made of breakable jaws connected to a rod on which the nut is mounted, the breakable jaws being provided on the outer surface with transverse teeth. The expansion anchor head is characterized in that one end of the rod (6) is in the form of a fork (5), to which the rotary jaws (1, 2) are attached by means of a pin (4), the rotary jaws (1, 2) folded together they have a front conical outer surface and are based on a spring (7) located on the rod (6) and supported on the other side by a nut (9), the rotary jaws (1 and 2) having triangular teeth (3) on the outer surface.
