Abstract
Sposób polega na jednoczesnym lub zsynchronizowanym, tak aby opóźnienie w odkręcaniu jednej śruby względem drugiej śruby pary połączeń śrubowych nie przekraczało dwóch obrotów, przyłożeniu do nakrętek pary połączeń śrubowych, mocujących element konstrukcyjny, na przykład jarzmo profilowe, momentu obrotowego działającego w kierunku zgodnym z kierunkiem odkręcania każdej z nakrętek, z rezerwą momentu wystarczającą do zerwania gwintów lub ukręcenia trzpieni śrub rozkręcanej pary połączeń śrubowych, przy czym obroty nakrętek są zsynchronizowane lub naprzemienne. Przedmiotem wynalazku jest także urządzenie do rozkręcania par połączeń śrubowych, zwłaszcza strzemion podatnej łukowej obudowy górniczej wyrobisk chodnikowych, które ma korpus (1) w kształcie prostokątnej, otwartej z góry i od dołu ramy o wzmocnionej konstrukcji, posiadającej z obu boków wystające po jednej stronie profilowe osłony boczne (2) o wzmocnionej konstrukcji, wyposażone w zaciski (3) do rozłącznego mocowania urządzenia do zewnętrznego elementu połączonego parą połączeń śrubowych, przy czym w korpusie (1) zamocowane są napędzane osie (5) dwóch zespołów odkręcających, ułożonych symetrycznie względem środka symetrii, które wystają poza wewnętrzną ścianę korpusu (1), pomiędzy osłonami bocznymi (2), i wyposażone są w gniazda, które z obu boków osłonięte są profilowymi osłonami bocznymi (2), natomiast każda z osi (5) połączona jest z napędowym zespołem odkręcającym, wyposażonym w zapadkę.The method consists in simultaneous or synchronized, so that the delay in unscrewing one screw relative to the other screw of a pair of bolted joints does not exceed two turns, applying to the nuts a pair of bolted joints, fastening the structural element, e.g. a profile yoke, of torque acting in the direction of unscrewing each nut, with a torque reserve sufficient to break the threads or twist the bolt bolts of the loose pair of bolted connections, with the nut rotation synchronized or alternating. The invention also relates to a device for unscrewing pairs of bolted connections, in particular stirrups of a flexible arched casing for roadheadings, which has a rectangular body (1) open from the top and bottom of the frame with a reinforced structure, with profile sides protruding on both sides side covers (2) with a reinforced structure, equipped with clamps (3) for releasable attachment of the device to an external element connected by a pair of bolted connections, while in the body (1) driven axles (5) of two unscrewing units are arranged, symmetrical in relation to the center of symmetry , which protrude beyond the inner wall of the body (1), between the side covers (2), and are equipped with sockets, which on both sides are covered with profile side covers (2), while each of the axles (5) is connected to the drive unscrewing assembly equipped with a latch.
