Description

Technical Field

[0001] The utility model relates to a device for loading and unloading a heat-insulating ladle cover of a die-cast steel-casting car in the field of die-cast steel-casting in the steelmaking industry, which can quickly load and unload the heat-insulating ladle cover before and after steel casting. Background Art

[0002] At present, the technology of casting steel on board a die-cast steel casting car has been widely promoted and used in the industry. In order to reduce the temperature drop rate of the molten steel during the movement of the steel casting car and the casting process, and to ensure the castability of the molten steel and the quality of the die-cast steel ingot products, it is necessary to install an insulation cover on the ladle in time before casting, and remove the cover in time after casting to facilitate slag turning and reduce slag sticking in the ladle. In the past, the installation of the ladle cover was done by the steel casting worker directing the overhead crane to the insulation ladle cover storage area, hanging the chain on the ladle cover lifting lug with tools, directing the overhead crane to lift the ladle cover above the ladle, covering the ladle and removing the chain. After the steel casting was completed, the overhead crane was directed to the ladle above the ladle, hanging the chain on the ladle cover lifting lug with tools to remove the ladle cover, and then hoisting it to the ladle cover storage area to remove the chain on the ladle cover lifting lug. This process required a steel casting worker and a overhead crane operator to travel back and forth between the ladle cover storage area and the die casting steel casting car, which was inefficient, labor-intensive, and had low per capita labor productivity. At the same time, loading and unloading the ladle cover above the steel casting area could easily cause foreign matter to enter the steel casting system and affect the intrinsic quality of the ingot. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings in current operations and provide a device for loading and unloading the insulation cover of a die-cast steel casting car ladle, which adopts a mechanical design to automatically load and unload the cover in a timely manner. It can avoid the labor intensity of steel casting workers and overhead crane workers traveling back and forth between the cover storage area and the steel casting area and loading and unloading the cover, thereby improving the efficiency of loading and unloading the cover.

[0004] The purpose of the utility model is achieved as follows: a device for loading and unloading the insulation cover of a die-cast steel casting car ladle, comprising a suspension frame, four suspension chains with one end fixed to a platform and the other end connected to the upper part of the suspension frame, four suspension hangers located at the lower part of the suspension frame for connecting the suspension fork arms, a cover body and a lifting lug for initially mounting the cover body on the ladle, two suspension fork arms fixed to the lower part of the four suspension hangers, two suspension grooves fixed to the upper part of the cover body, reinforcement ribs for strengthening the strength of the suspension grooves are provided on the cover body, and two suspension fork arms are respectively inserted into the two suspension grooves.

[0005] The suspension frame is formed by welding four 12# I-steels into a square frame. Four suspension points are arranged above the square frame. The square frame is fixed to the bottom of the cross beam of the platform through a suspension chain.

[0006] The suspension fork arm is made of a Q235 steel plate with a size of 1500mm*140mm*20mm and is connected to a suspension frame through two suspension rods with a size of 420mm*140mm*20mm.

[0007] The hanging groove is welded from two steel plates measuring 2800*300*20mm and two steel plates measuring 2800*80*20mm, and is fixed to the top of the cover body. A 30-40mm wide gap is left at the top of the hanging groove to facilitate the insertion of the hanging fork arm into the hanging groove.

[0008] The reinforcing ribs are cut from 300*200*20mm steel plates and are symmetrically welded to both sides of the suspension groove according to the drawings to serve as reinforcement.

[0009] The lifting lugs are made of Q235 steel plates and are welded to the outside of the hanging slots at the center line of the ladle cover body, and are used for initially installing the ladle cover on the ladle.

[0010] The beneficial effects of the present invention are as follows: (1) The suspension device is hung under the platform in a four-point suspension manner, and the force is evenly distributed; (2) Carbon steel plates and I-beams are welded, and the material is light and fully utilizes the on-site materials; (3) The up-and-down, forward-and-backward, and left-and-right movement functions of the die-cast steel casting vehicle are utilized, and the design of a suspension fork arm + suspension slot is adopted, which facilitates the installation of insulation before and after steel casting and the timely removal of the covers after steel casting, greatly reducing the workload of steel casting workers, overhead crane operators and other personnel, improving work efficiency, reducing ineffective labor, and improving labor productivity.
