Abstract
Zgłoszenie dotyczy sekcji obudowy zmechanizowanej skrzyżowania ściany z chodnikiem przyścianowym, przydatnej w górnictwie podziemnym węgla kamiennego. Zgodnie z wynalazkiem sekcja (6) obudowy zmechanizowanej skrzyżowania ściany (1) z chodnikiem przyścianowym (3) ma przyłączony przesuwnie i przegubowo z przodu człon podporowy przedni (11) ze stropnicą (12) podpartą stojakiem osadzonym na spągnicy przedniej. Stropnica (12) ma stropnice teleskopowe wysuwne w przód i osłony boczne (16), a także moduł likwidacyjny odrzwi obudowy chodnikowej (4). Moduł likwidacyjny posiada przesuwny w pionie kosz dla obsługi, oraz dźwignik do operowania elementami obudowy chodnikowej (4). Kosz osadzony jest korzystnie na pantografowym układzie dźwigni sterowanym siłownikiem. Dźwignik jest siłownikiem hydraulicznym o dużym skoku o położeniu regulowanym siłownikami korekcyjnymi, wyposażonym od góry w korytkowy uchwyt, przystosowany do kształtu elementów obudowy chodnikowej (4).
