FIELD: transport engineering. SUBSTANCE: proposed bunk clamping device contains support beam and base 1 installed by means of vertical axle 2 and support plate on frame of self-propelled chassis 3, with triple-arm levers 6, 7 being hinge mounted on support plate posts. Outer arms of levers are located higher than their turning axles, and opening drives are connected to lower arms of levers arranged out of the limits of posts and also lower ends of wire ropes arranged in crosswise manner vertical plane, some ends of wire ropes being secured on upper ends of levers. Each wire rope is reeved through sheave. Length of inner arms 13, 14 between levers is equal to or greater than distance between lever turning axles. Opening hydraulic cylinders 21, 22 are hinge-secured on base by their housing. Rods of hydraulic cylinders are hinge-connected to lower arms of triple-arm levers. Support beam is formed by inner arms of levers on which said wire rope sheaves are installed. EFFECT: simplified design, reduced metal usage, improved reliability. 4 cl, 3 dwg |
