The invention relates to a ladle delivery truck manipulator with a safety device, which is mainly used for delivering molten steel between different places. The manipulator comprises a large working arm (6); one end of the large working arm (6) is articulated with a ladle delivery truck (8); the middle of the large working arm (6) is connected with the ladle delivery truck (8) through a large hydrocylinder (9); the other end of the large working arm (6) is provided with a trunnion opening (5) which is stuck on a trunnion axis (4) on a ladle (7). The manipulator is characterized in that the large working arm (6) at the side of the trunnion opening (5) is connected with a safety device; the safety device comprises a hydrocylinder (2) and a locking sheet (1); the tail of the hydrocylinder (2) is articulated with the large working arm (6) at the side of the trunnion opening (5) via a connecting pin (3); a piston rod of the hydrocylinder (2) is articulated with one end of the locking sheet (1); the middle of the locking sheet (1) is revolvably connected beside the trunnion opening (5) and the other end of the locking sheet (1) is freely arranged. The invention can seal the trunnion axis of the ladle in the trunnion opening of the manipulator, thus greatly improving the safety property of the ladle delivery truck manipulator.
Description
(1) Technical field [0001] The invention relates to a steel ladle delivery vehicle, in particular to a steel ladle delivery vehicle manipulator. It is mainly used for transporting molten steel in different places. It belongs to the technical field of metallurgical machinery. (2) Background technology [0002] Domestic and foreign iron and steel industry all adopts rail transport vehicle to transport molten steel in steelmaking workshop before the 1980s. Suppressed by the track, this mode of transport can only be transported to a designated location, the transport point is restricted, and the cost of the rail transport vehicle is high. After the 1980s, ladle trucks were gradually used to transport molten steel. The ladle transport vehicle is flexible and convenient for transporting molten steel, and can be transported to any place without being limited by the track. However, in the process of transportation, because the road is sometimes uneven, the ladle must always be k...
