Described steel ladle covering/uncovering device is additionally provided with hydraulic power unit and electric-control system.
Described base frames 2 is welded on mechanism's door frame 1.
In order to solve the problem of prior art existence and overcome its defect, it is achieved meet process for making requirement and play good heat insulation effect, energy-saving and cost-reducing goal of the invention, the technical scheme that the present invention takes is:
As shown in Figure 1 to Figure 3, steel ladle covering/uncovering device provided by the present invention, described base frames 2 is provided with slider bar 3, described slider bar 3 is provided with hoisting frame 4, described hoisting frame 4 is arranged in described slider bar 3 by limited post framework 8, and is formed with the vertical rod member of described limited post framework 8 and be slidably matched；Described hoisting frame 4 arranges the hook 7 extended downwardly from；Setting hoisting frame lift drive mechanism in described slider bar 3, described hoisting frame lift drive mechanism is connected with described hoisting frame 4 and drives it to make elevating movement；Arranging slider bar horizontal movement drive mechanism in described base frames 2, described slider bar horizontal movement drive mechanism is connected with described slider bar 3 and drives it to move horizontally.
Slider bar 3 is arranged in base frames 2, and described hook 7 is welded on hoisting frame 4.
Described hook 7 has special version and a position relationship, and hook 7 is plane with the contact surface of clad, it is to avoid the phenomenon cannot added a cover after taking off lid, and the quantity of hook is relevant with steel mill situation, 3 to 4.With steel ladle cover with the use of, hook clad to complete take off lid action and tangle clad.
Use the present invention can fully meet process for making requirement and play good heat insulation effect, energy-saving and cost-reducing, bring economic benefit for steel mill.For omnidistance steel ladle covering/uncovering, and can long-time stable reliably operate.Can use under steel mill's process for making vertical with ladle direct of travel of suspension arm direction, it is achieved the most omnidistance uncovery function, possess simple and reliable for structure, safety and stability, maintenance is little, practical, easy to use, the advantage that holding time is little.
Described hoisting frame lift drive mechanism sets hoist cylinder 5 in described slider bar 3, is provided with the hoist cylinder 5 realizing hook 7 integral elevatings between hoisting frame 4 and slider bar 3.Described hoist cylinder 5 piston rod is connected with described hoisting frame 4.
Hoist cylinder 5 realizes hoisting frame 4 and the lifting of hook 7, and is realized the lifting of steel ladle cover by hook 7.
Described slider bar horizontal movement drive mechanism sets traversing oil cylinder 6 in described base frames 2, and the piston rod of described traversing oil cylinder 6 is connected with described slider bar 3.
Under the effect of traversing oil cylinder 6, slider bar 3 can be slided with respect thereto frame 2 with hoisting frame 4, hooks clad and detaches the effect of Bao Gai reaching to link up with 7.
The gib head of described hook 7 is horizontal gib head, and when described steel ladle covering/uncovering device is in and adds a cover or take off lid, the steel ladle cover peg on described steel ladle cover contacts with the horizontal plane on horizontal gib head.So, in the horizontal movement of hook 7, the effect hooked by steel ladle cover can be realized.
