Dual-purpose travelling crane hoisting device

Abstract

The dual-purpose traveling crane hoisting device comprises a cross beam, supporting columns are fixedly installed on the left portion and the right portion of the lower end of the cross beam, a connecting base is installed at the lower end of the cross beam in a sliding mode, and chains are fixedly installed on the left portion and the right portion of the lower end of the connecting base. The lower ends of the two chains are jointly and fixedly provided with a mounting plate, and the outer surface of the mounting plate is fixedly sleeved with a supporting frame. According to the dual-purpose travelling crane hoisting device disclosed by the utility model, the supporting frame is arranged, so that when the equipment needs to hoist a fan-shaped section of a continuous casting machine, the reinforcing bolts are firstly detached from the through holes and the connecting frame, and the connecting frame is detached from the supporting frame, so that the support is convenient to detach; the contact between the plate hook and the fan-shaped section of the continuous casting machine can be avoided; by arranging the support, when the equipment needs to hoist the tundish, the single hook can be prevented from being in contact with the tundish due to the fact that the lower end face of the single hook is lower than the lower end face of the support.

Description

Technical Field

[0001] The utility model relates to the technical field of lifting equipment, in particular to a dual-purpose traveling crane lifting device. Background Art

[0002] The crane is an indispensable equipment for the metallurgical steelmaking system, and its purpose is to lift metallurgical equipment and liquid metal. The crane that lifts the liquid metal container must use a metallurgical casting crane in accordance with safety requirements, and use a fixed gantry hook to lift the liquid metal container; in particular, four gantry hooks are required to lift the tundish containing molten steel for continuous casting, which limits the use of the crane's main lifting mechanism to lifting the tundish. During the equipment maintenance of the slab continuous casting machine, the fan-shaped segment equipment used needs to be replaced, and a single hook is required to lift the device for replacing the fan-shaped segment; although the fan-shaped segment of the continuous casting machine has a high service life, it still needs to be replaced about once a month on average, and each replacement takes about 3 hours.

[0003] The existing dual-purpose crane hoisting device has the following drawbacks. For the safety of crane hoisting liquid metal, a metallurgical casting crane must be used, and the hoisting device used must be a fixed gantry hook to lift the container containing liquid metal. The continuous casting machine segment replacement device uses a rotatable single hook; the two are not compatible. That is, the plate hook that hangs the tundish containing molten steel cannot hang the segment replacement device, and the single hook that hangs the segment replacement device cannot lift the continuous casting tundish. Since the distance between the existing plate hooks is mostly fixed, and the sizes of the tundishes are different, the equipment has certain limitations. Therefore, we propose a new dual-purpose crane hoisting device. Utility Model Content

[0004] The main purpose of the utility model is to provide a dual-purpose crane hoisting device, which can effectively solve the problem of inconvenient switching between a plate hook and a single hook.
