Description

Nastepnie zaciska sie wstepnie szczeki na linie za pomoca sprezyny: wciagarka jest przygotowana do pracy. Wychylajac dzwignie 7 wokól osi obrotu 6 wywoluje sie ruch wahadlowy dzwigni dwuramiennej 8, która na przemian przybliza i oddala od siebie korpusy 10 i 12, w których sa osadzone szczeki 17 i 18. Sila tarcia pomiedzy lina i szczekami powoduje obrót dzwigni 14 wokól osi 13, a tym samym — zmniejszanie (zwiekszanie) szczeliny pomiedzy szczekami na skutek obrotu czopów 16 w szczekach 17 oraz koncówek walcowych 15 we wglebieniach B szczek plaskich 18. Kiedy jedna para szczek jest zacisnieta i ciagnie line, druga jest rozluzniona i slizga sie po tej linie. Operacja ta powtarza sie periodycznie, co powoduje przesuwanie liny wzgledem kadluba wciagarki. PL PLThe jaws are then pre-clamped on the rope with a spring: the winch is ready for operation. Swiveling the levers 7 around the axis of rotation 6 causes the swinging movement of the two-armed lever 8, which alternately brings the bodies 10 and 12, in which the jaws 17 and 18 are mounted, alternately. The friction force between the rope and the jaws causes the rotation of the lever 14 around the axis 13 thus - reducing (increasing) the gap between the jaws due to the rotation of the pivots 16 in the jaws 17 and the cylindrical ends 15 in the recesses B of the flat jaws 18. When one pair of jaws is tightened and pulls the line, the other is slack and slides along this line . This operation is repeated periodically, which causes the rope to move in relation to the hull of the winch. PL PL

Claims

1. Patent claim A jaw puller, consisting of a line pulling mechanism, which is a system of two pairs of jaws alternately loosened and clamped on a rope by a two-arm swinging lever, which simultaneously brings both pairs of jaws closer and away in their movement along the rope, characterized by the fact that every pair of two known jaws; flat (18) and shaped (17) (similar to the letter "U" and flat around the jaw) is mounted on two one-armed levers (14), the rotation axes of which (13) are placed in the body (10) 80069 3 surrounding the jaws with on both sides, while the upper arms of the lever have cylindrical ends (15) provided with eccentrically located cylindrical pins (16) cooperating with holes in the arms of the shaped jaw, while the flat jaw has two cylindrical indentations (B), into which cylindrical tips (15) are inserted ) of the lever and thus enable the mutual contact and movement of flat and shaped jaws .KI. 35cr 3/00 80 069 MKP B66d 3/00 yjredo Work.
