DEVICE FOR ERECTING GROOVED AND TONGUED WALL Russian patent published in 1996 - IPC

FIELD: hydraulic engineering. SUBSTANCE: mechanism to plunge the tongue is made in the form of retractor power hydraulic cylinder equipped with a member to couple to the tongue, and placed on a cross bar. The cross bar is installed on U- shaped pontoon and may reciprocate along pontoon slot. One end of the cross bar is provided with rotary platform with lifting boom, besides the pontoon is additionally equipped with a roller conveyor placed along pontoon slot on the side of lifting boom. Collector of tongues made in the form of at least two chain conveyors with crosswise axis of which is perpendicular to crosswise axis of the roller conveyor is installed on the deck of the pontoon between the roller conveyor and pontoon board. Support-fixing piles are provided with mechanisms for pontoon self-lifting. The mechanisms are made in the form of retractor hydraulic cylinders installed on the pontoon so to enable interact with the piles. The pontoon is additionally provided with arm crane enable to move crosswise along the pontoon. EFFECT: decreased level of labour consumption. 5 cl, 3 dwg
