Abstract

The invention relates to a blocking device for a milling machine used in pipe cleaning and pipe restoration. Said device consists of a cylindrical blocking element (1) in which two tubular plungers (2) are arranged in a mirror-symmetrical manner. When pressure is exerted on the two tubular plungers from the rear the blocking arms (8) connected to the tubular pistons via a push rod (4) spread virtually X-like radially outwards and block the blocking element (1) in the pipe. When the pressure is released pressure springs (6) mounted on the tubular plungers return the blocking arms to their initial position. The blocking device provided for in the invention has small radial dimensions, can be blocked concentrically in the pipe, has a simple structure and can also be used in bent pipes.
