Technical Examples

The invention concerns a clamp coupling for coupling pairs of pipes. Such clamp couplings are used, for example, for coupling concrete conduits from concrete pumps. This clamp coupling (10) comprises two clamp shells (16, 18) which, in the coupling state, define a circular opening (14) for the passage-through of the pipes. The coupling shells can be pivoted relative to each other via a pivot linkage (20) at their one end, and have a locking mechanism (26) provided at their other end. In order to be able to fasten the clamp coupling (10) even in confined spaces, the locking mechanism (26) comprises a locking hook (30) which, in the closed state, positively grasps a latch pin (24) provided on the other coupling clamp (16), and pulls the clamp shells (16, 18) towards each other at their point of separation (28) opposite the linkage (20). During the opening process, the locking hook (30) can be lifted from the latch pin (24) and pivoted out of its engaged position about a pivoting axis (32) which is perpendicular to the linkage axis (22). The locking mechanism (26) also comprises a clamping lever (36) which can be pivoted relative to the coupling clamp about a lever axis (34) which is perpendicular to the linkage axis. The clamping lever is also operatively associated with the locking hook (30).
