Abstract

Modułowa górnicza obudowa zmechanizowana skrzyżowania z odzyskiwaniem węgla z chodnika przyścianowego w podbierkowym systemie pracy, charakteryzuje się tym, że na końcach stropnic (1.1) modułów bocznych (1) zamocowane są obrotowo belki górne (3), które z drugiej strony także obrotowo, połączone są z pionowymi łącznikami tylnymi (4) swym drugim końcem połączonymi również obrotowo ze spągnicami krótkimi (5) zamocowanymi swym drugim końcem obrotowo do końców spągnic (1.2) modułów bocznych (1). Na końcu stropnicy modułu środkowego (2) zamocowana jest segmentowa osłona odzawałowa (6), mająca osłonę zasadniczą z jednej strony połączoną obrotowo ze stropnicą modułu środkowego (2) i połączoną z drugiej strony obrotowo do osłony zasadniczej osłonę wychylną oraz zabudowaną wewnątrz osłony wychylnej osłonę wysuwną. Osłona zasadnicza podparta jest połączonymi z nią obrotowo podporowymi siłownikami hydraulicznymi (7) mocowanymi drugą stroną obrotowo do poprzecznej belki łączącej spągnice modułu środkowego (2). Osłona zasadnicza również połączona jest obrotowo z siłownikami hydraulicznymi wychylenia (9) drugim swym końcem połączonymi obrotowo z osłoną wychylną. Osłona wychylna w pobliżu swej osi obrotu połączona jest obrotowo z siłownikami hydraulicznymi wysuwu, których drugi koniec połączony jest obrotowo z końcową częścią osłony wysuwnej.Modular mining mechanized support for the intersection with the recovery of coal from the longwall heading in the landing work system, characterized by the fact that at the ends of the canopy (1.1) of the side modules (1) upper beams (3) are rotatably mounted, which on the other side are also pivotally connected with vertical rear links (4) also pivotally connected with short runners (5) pivotally attached with their other end to the ends of the runners (1.2) of the side modules (1). At the end of the canopy of the central module (2), a segmented caving cover (6) is mounted, which has a main cover on one side pivotally connected to the canopy of the central module (2) and on the other side pivotally connected to the main cover and a tilting cover built inside the hinged cover. . The main guard is supported by pivotally connected support hydraulic cylinders (7), rotatably attached with the other side to the transverse beam connecting the runners of the central module (2). The main guard is also rotatably connected to the hydraulic cylinders of the tilt (9) with its other end being pivotally connected to the tilting guard. The swivel guard is rotatably connected near its axis of rotation with hydraulic cylinders of the extension, the other end of which is pivotally connected to the end part of the slide guard.
