A MECHANISM FOR ASSEMBLING OF PLASTIC SEWAGE CONDUITS MADE OF PIPES WITH EXTERNAL RIBBING

摘要

A mechanism designed for assembling of plastic sewage conduits made of pipes with external ribbing has clamping parts made of two ridge semi-coupling boxes (1) in form of a half-cylinder with elongated planar surfaces, which have grooves from the inside in size corresponding with the size of ribs (8) of the pipes (6, 7). One ridge semi-coupling box (1), with roll necks(2), is equipped with one-arm levers (4) and the second ridge semi-coupling box (1), with roll necks (2), is equipped with drawbars ( 3), which have, in the end, U-shaped slots. One-arm levers (4) are, furthermore, equipped with pins (5) which being in interaction with drawbar (3) slots form a mechanism producing an axial power, which is via ridge semi-coupling boxes (1) transmitted to the pipes (6, 7). Using of sliding plates might ease the pipes (6, 7) movement.
