Abstract
Sygnalizator rozwarstwień warstw stropowych, znajdujący zastosowanie do sygnalizacji rozwarstwienia stropu w górnictwie zwłaszcza górnictwie metali nieżelaznych, wyposażony jest w głowicę rozprężną (1) z jedno, albo dwu albo wieloelementową żerdzią (2), na której wolnym gwintowanym końcu (3) osadzony jest rdzeń pomiarowy (4), który tworzą ścięty stożek przechodzący w graniastosłup sześciokątny z gwintowanym przelotowym otworem. Na zewnętrznej powierzchni ściętego stożka ściętego osadzone są elementy mierzące (8). Gwintowany koniec (3) żerdzi (2) zawiera płetwę montażową (10).The floor layer delamination indicator, used for signaling the delamination of the roof in mining, especially in the mining of non-ferrous metals, is equipped with an expansion head (1) with one, two or multi-element rod (2), on which the free threaded end (3) is mounted the measuring core (4) formed by a truncated cone passing into a hexagonal prism with a threaded through hole. Measuring elements (8) are mounted on the outer surface of the truncated cone. The threaded end (3) of the pole (2) includes a mounting fin (10).
