Abstract

Inventia se refera la un cleste pentru prinderea si rotireamaterialului tubular si în special, a unor burlane de tubare a unei gauri forate în scopul, de exemplu, exploatarii fluidelor dintr-un strat petrolifer. Clestele, conform inventiei are într-o coroana dintata montate niste came de rulare, plasate simetric fata de o axa de simetrie care trece printr-o fereastra a unei carcase si situate în planuri orizontale diferite, de-a lungul carora se pot deplasa niste role, montate la rîndul lor cu o posibilitate de rotire pe niste capete libere ale unor pîrghii de acestea din urma fiind articulate si niste falci contactul dintre role si came avînd loc numai dupa ce un suport în forma de semiluna, de care sunt articulate pîrghiile prin rotire, a ajuns în dreptul ferestrei carcasei amintite.
