Abstract

Przedmiotem wynalazku jest urządzenie do pomiaru rozwartości rys, szczelin lub pęknięć zwłaszcza w obudowie szybu górniczego lub w wielkogabarytowych komorach górniczych, które składa się z pierwszej płytki (1) oraz drugiej płytki (2) zaopatrzonych w otwory mocujące, umożliwiające sztywne zamocowanie pierwszej płytki (1) i drugiej płytki (2) do badanego elementu, w ten sposób, że pierwsza płytka (1) i druga płytka (2) mocowane są do powierzchni po przeciwległych stronach rysy, szczeliny lub pęknięcia. Urządzenie to zawiera diody (6) oraz płytkę obwodu drukowanego (4) z wydrukowanymi ścieżkami przewodzącymi (5), przy czym jedna ze ścieżek (5) stanowi masę a pozostałe ścieżki przewodzące połączone są z diodami (6), przy czym diody (6) oraz płytka obwodu drukowanego (4) przymocowane są do drugiej płytki (2) a do pierwszej płytki (1) zamocowany jest pierwszy koniec dołączonej do napięcia ujemnego wydłużonej przewodzącej płytki (3), której drugi koniec połączony jest w sposób przesuwny z wydrukowanymi ścieżkami przewodzącymi (5), przy czym przewodząca płytka (3) dołączona jest do napięcia ujemnego.The subject of the invention is a device for measuring the width of cracks, gaps or cracks, especially in the casing of a mining shaft or in large-size mining chambers, which consists of a first plate (1) and a second plate (2) provided with mounting holes enabling rigid fixing of the first plate (1). ) and the second plate (2) to the test piece, such that the first plate (1) and the second plate (2) are attached to the surfaces on opposite sides of the scratch, slot or crack. The device comprises diodes (6) and a printed circuit board (4) with printed conductive tracks (5), one of the tracks (5) being ground and the other conductive tracks connected to the diodes (6), the diodes (6) and the printed circuit board (4) is attached to the second board (2) and the first end of the negatively connected elongated conductive board (3) is attached to the first board (1), the other end of which is slidably connected to the printed conductive tracks ( 5), with the conductive plate (3) connected to the negative voltage.
