Ladle Hook

Ladle spreader, gantry hook spreader, ladle spreader, ladle spreader, gantry hook lifting beam, ladle hook, ladle spreader are mainly used for the hoisting of tun-dish, hot metal tank, ladle and ladle in various steel plants, with simple structure, convenient operation, safety, and reliability. The beam body is made of high-quality low-carbon alloy steel, with high strength and high- temperature resistance. The hook body is made of steel plate splicing and riveting, with high strength and flexibility. At the same time, the hook body can rotate freely from front to back, left and right, which is easy to hook.

Gantry plate hook spreader is an important spreader for lifting the hot metal tank and ladle in the metallurgical foundry, as well as the spreader for tipping hot metal tank and ladle to realize hot metal feeding into the furnace and molten steel casting. In the steelmaking workshop, the molten iron transported from the ironmaking workshop is poured into the mixer with gantry plate hook spreader, and the molten iron in the mixer is directly poured into the converter; The ladle is lifted by the gantry plate hook spreader, and the molten steel is lifted to the tundish and caster to complete the casting work. In the hoisting and transportation of molten iron and steel in the metallurgical foundry, gantry plate hook spreader is widely used as the key process equipment or important auxiliary tooling.

The gantry plate hook spreader in the prior art is mainly composed of a lifting climb, a crossbeam, a pin shaft, a lifting fork, and a plate hook. The traditional method of using the gantry plate hook sling is to hook the hook of the crane to the lifting pan of the gantry plate hook sling, and through the plate hook to hook the trunnion of the hot metal tank and ladle, to realize the lifting of the hot metal tank and ladle, as well as the tipping of the hot metal tank. In the process of using the existing gantry plate hook spreader, due to the proficiency of crane operators, the collision of foreign objects, and other reasons, it is easy to cause decoupling, leading to major safety accidents, causing casualties, and equipment damage. At the same time, the lifting pan is an important force- bearing component, which is generally made of forgings. The requirements for material and forging forming are relatively high, resulting in high manufacturing costs. Therefore, the key to solving this problem is to research and develop a gantry plate hook sling with simple structure, reliable use and effectively avoiding decoupling.

The purpose of the utility model is realized in this way, including a crossbeam, a lifting fork, a pin shaft I, a pin shaft II and a plate hook; The hanging fork and the cross beam are connected by a pin shaft I; The lower end of the hanging fork is provided with a plate hook; The hanging fork and the plate hook are connected by a pin shaft II; A pulley block is arranged on the end face above the cross beam, and the crossbeam is fixedly connected with the pulley block; The pulley block is located in the middle of the cross beam; The lower part of the cross beam is provided with a heat insulation plate, and the cross beam is fixedly connected with the heat insulation plate.

The utility model sets the pulley block of the hook on the lifting trolley on the crossbeam of the gantry plate hook spreader, connects the gantry plate hook spreader and the lifting trolley as a whole through the winding of the steel wire rope, and effectively avoids the occurrence of the decoupling accident. The utility model cancels the hook head of the hook group on the lifting trolley, cancels the lifting climbing of the original gantry plate hook spreader, and changes the original hanging climbing of the gantry plate hook spreader through the crane hook into the winding of the steel wire rope and the pulley block of the crane, so as to complete the plate hook hanging the trunnion of the hot metal tank and the ladle, and realize the lifting of the hot metal tank and the ladle, In use, the decoupling phenomenon is avoided, and the use safety of gantry plate hook spreader is further improved. At the same time, the hook head on the hook group and the lifting climbing on the gantry plate hook spreader is canceled, which reduces the manufacturing cost of the crane and increases the net lifting height of the crane. The utility model has the advantages of simple structure and reliable use, and can effectively avoid the separation between the gantry plate hook spreader and the lifting trolley.
