Abstract

Inventia se refera la un stand pentru probarea la efort a unei bucati de material tubular, cum ar fi, de exemplu, o prajina de forare, supusa în timpul lucrului atît la o forta de tractiune, cît si la un moment de torsiune. Standul, conform inventiei, este alcatuit dintr-un suport vertical fix, pe care sînt fixate niste camasi ale unor cilindri hidraulici, acestia din urma avînd niste tije fixate de un suport vertical mobil, în suporturi superior, fiind montati, cu posibilitate de rotire, niste arbori, dispusi coaxial, în legatura cu care sînt montate niste flanse exterioare si respectiv niste flanse interioare, de arbori fiind articulate, în dreptul flanselor exterioare, niste balansiere duble, în legatura cu care sînt montate cîte doua servomotoare, avînd axele longitudinale paralele între ele, inferior balansierele fiind articulate de o bara de egalizare, care este sustinuta, cu posibilitate de rotire, de catre suporturi, iar între flansele interioare este dispusa o bucata de material tubular.The invention relates to a stand for the testing of a piece of tubular material, such as, for example, a drilling surface, subjected during work to both a traction force and a torsional moment. According to the invention, the stand is made up of a fixed vertical support, on which are mounted some shirts of hydraulic cylinders, the latter having rods fixed by a movable vertical support, in upper supports, being rotatably mounted, some coaxially arranged shafts in connection with which are mounted outer flanges and respective inner flanges, the shafts being articulated, beside the outer flanges, with two double balancers, in connection with which are mounted two servomotors having the parallel longitudinal axes between the lower ones being articulated by an equalizing bar which is rotatably supported by the supports, and a tubular piece is disposed between the inner flanges.
