Abstract

An arrangement for guiding drill rods in an extension rod drilling equipment, comprising an intermediate centralizer (4) mounted on a feeding beam (1) and having a drilling centre opening (8) and a rod exchanger (5) mounted at the side of the feeding beam and comprising a displacing means (19) provided with a retaining opening (24). The displacing means is displaceable from the side of the centralizer to a displacement position in which the retaining opening (24) is positioned concentrically with the centre opening (8). The centralizer is provided with a closing means (18) closing the periphery of the centre opening and with a guiding means (17) for displacing said closing means. The guiding means is positioned on the path of movement (B) of the displacing means so that the movement of the displacing means to the displacement position pushes the closing means away from the retaining position.
