Description

Ladle cart equipped with fastening device {Ladler car equipped with locking apparatus}

The present invention relates to a ladle cart for electric tapping operation, and more particularly to a ladle cart equipped with a fastening device to facilitate the withdrawal of the molten ladle cart.

Due to slag boilling during the electric tapping operation, the slag overflows and accumulates around the rail to which the molten ladle bogie moves, thereby making it difficult to move by the self-power of the ladle bogie. In this case, the melt ladle bogie is drawn out by using the power of another ladle bogie, and for this purpose, the melt ladle bogie and the other ladle bogie are connected by a wire rope or a chain. At this time, a worker (2 ~ 3 people) who has a lifespan (2 ~ 3) pulls a wire rope or chain of about 80kg and fastens it to the hook for emergency withdrawal of the molten ladle cart, which exposes the worker to danger. In other words, diseases such as the musculoskeletal system or eye failure may occur due to breakage of the wire rope or the weight of the chain, and a burn or the like may be caused by high heat radiant heat caused by slag and molten steel. In addition, it is difficult to manage the workplace environment because wire ropes or chains have to be jade around the workplace at all times, and long-term input and waiting time of many workers lead to a decrease in productivity.

An object of the present invention is to provide a ladle trolley provided with a fastening device that can facilitate the withdrawal of the molten ladle trolley.

Another object of the present invention is to provide a ladle trolley provided with a fastening device that can prevent a disaster occurring in the withdrawal process of the molten ladle trolley cart.

Ladle bogie provided with a fastening device according to an aspect of the present invention for achieving the above object is installed on one side of the ladle bogie and the frame is provided with a ring at the end, fastening ring is arranged to be pivotable on the frame And a fixing lever inserted into the ring of the frame and supporting the fastening ring from the bottom, and removing the fastening lever from the ring so that the fastening ring falls by its own weight, and the fastening ring faces the molten ladle bogie. It is characterized in that coupled to the hook.

The frame is disposed so as to face each other at a predetermined interval and the first and second frames provided with the ring at the end portion, the support portion disposed below the first and second frame and supporting the fastening ring to be pivotable; And a stopper disposed above the frame to limit the pivot of the fastening ring.

In addition, the fastening ring is connected to the ladle cart through a chain of a predetermined length, characterized in that the supporting portion for supporting and storing the chain on the side of the ladle cart is provided.

Ladle trolley of the present invention is provided with a fastening device that can easily couple the fastening ring to the take-out hook of the molten ladle trolley. The fastening device is a structure in which the fastening ring is coupled to the hook by its own weight by the operator removing the fixed lever. It is suitable when you want to withdraw molten ladle cart. According to the present invention, since the worker does not directly handle heavy wire ropes or chains, and is not exposed to high temperature slag and molten steel, safety accidents and casualties can be prevented, and the operating atmosphere can be reduced and facility management can be easily performed. .

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are provided to those skilled in the art to fully understand the present invention, and may be modified in various forms, and the scope of the present invention is limited to the embodiments described below. no.
