Abstract

Inventia se refera la un dispozitiv pentru masurarea miscarii ancorelor, avînd utilizare în domeniul sustinerii lucrarilor miniere în special în activitatea topografica din subteran. Dispozitivul se caracterizeaza prin aceea ca, în scopul depistariiimediate a eventualelor miscari ale ancorelor de sustinere a lucrarilor de sustinere a lucrarilor miniere subterane este alcatuit dintr-o piesa cilindrica ce poate fi montata pe tija unei ancore de sustinere. Piesa cilindrica este prevazuta la interior cu niste caneluri în care sunt montate niste inele gradate ce pot fi strînse pe piesa cilindrica cu ajutorul unor suruburi ce traverseaza niste urechi apartinînd inelelor gradate pe care sunt sudate cîte un bolt filetat pentru fixarea unei piese racord destinata sustinerii unui raportor si a unui brat de racordare prevazut cu un orificiu pozitionat pe bratul de racordare în dreptul gradatiilor de pe raportor astfel încît sa poata fi citita orice modificare a înclinarii ancorei fata de o pozitie initiala. Bratul de racordare este prevazut cu un capat filetat pentru a permite fixarea între dispozitivele de masurare a miscarii a doua ancore vecine si a unui distantier extensibil gradat care sa permita determinarea modificarilor distantei dintre tijele ancorelor.The invention relates to a device for measuring the anchor movement, being used in the field of supporting the mining works especially in topographical activity in the underground. The device is characterized by the fact that, in order to detect immediately the possible movements of the supporting anchors of the support works for the underground mining works, it consists of a cylindrical piece which can be mounted on the stem of a support anchor. The cylindrical part is provided with some grooves in the interior with some graduated rings which can be clamped on the cylindrical piece by means of screws passing through some ears belonging to the graduated rings on which are welded a threaded bolt for fixing a connecting piece for supporting a and a connecting arm provided with a hole positioned on the connection arm at the marker's gradient so that any modification of the inclination of the anchor from an initial position can be read. The connecting arm is provided with a threaded end to allow the two moving anchors to move between the two adjacent anchors and a graduated extensible spacer to determine the changes in the distance between the anchor rods.
