Detailed description of the invention
Below against accompanying drawing, by the description to embodiment, the detailed description of the invention of the present invention is made into
One step detailed description, to help those skilled in the art to the inventive concept of the present invention, skill
Art scheme has more complete, accurate and deep understanding.
The structure of the present invention as shown in Figures 1 to 6, for a kind of steel ladle covering/uncovering device, is used for steel
Steel ladle cover 9 on bag 8 carries out adding a cover and take off lid operation, for omnidistance steel ladle covering/uncovering, can meet
The technological requirement of steel mill, reaches intended heat insulation effect simultaneously, and energy long-time stable is reliably
Operating.
Described covering/uncovering device includes mechanism's door frame 1, mechanism body 2 and hoisting mechanism 3；Also include liquid
Press pump station and electric-control system.
Mechanism body 2 is arranged on mechanism's door frame 1；Described ladle 8 is placed on buggy ladle 13, by steel

In order to solve the problem of prior art existence and overcome its defect, it is achieved improve heat insulation effect energy
Long-time stable, the goal of the invention reliably operated, the technical scheme that the present invention takes is:
As shown in Figures 1 to 6, the steel ladle covering/uncovering device of the present invention, described hoisting mechanism 3 is provided with water
Flat plug-in type suspension hook 5, the rearward end of described horizontal plug-in type suspension hook 5 is by vertical connector
It is fastenedly connected with described mechanism body 2；
The surface of described steel ladle cover 9 is provided with steel ladle cover peg 10；
When described steel ladle covering/uncovering device is in and adds a cover or take off lid, described is horizontally inserted
Formula is hung
Hook 5 inserts described steel ladle cover peg 10.
Described horizontal plug-in type suspension hook 5 also referred to as oblique cutting toothing, described horizontal plug-in type suspension hook 5
It is arranged on the oblique cutting tooth pedestal of mechanism body 2.
As it is shown in figure 1, described horizontal plug-in type suspension hook 5 has special version and position relationship
, it can be three or four that the quantity of horizontal plug-in type suspension hook 5 regards service condition.It is horizontally inserted
Formula suspension hook 5 and steel ladle cover 9 with the use of.
In normal steelmaking process, steel ladle covering/uncovering device need not be carried out any operation, at ladle 8
Running is carried out automatically add a cover or take off lid；Also can mention clad by elongation hoist cylinder to reach
The effect do not added a cover to ladle, to tackle the emergency situations in steelmaking process.
Horizontal plug-in type suspension hook 5 uses special version, and ladle can carry out adding a cover and taking off lid automatically.
As shown in Figure 6, there are abnormal conditions in steel-making, when needing not add a cover through device, by lifting oil
Cylinder 4 mentions hoisting mechanism 3, mechanism body 2 and four horizontal plug-in type suspension hooks 5, and by steel ladle cover
9 rise to certain altitude, to get out of the way ladle 8.
The present invention by above structure, steel mill that can be consistent with ladle 8 direct of travel in suspension arm direction
Use under process for making, it is achieved the most omnidistance uncovery function, steel mill can be met completely and produce
During to molten steel insulation, energy-saving and cost-reducing requirement, possess simple and reliable for structure, maintenance is little
, practical, easy to use, the advantage of not extra holding time.
As depicted in figs. 1 and 2, described horizontal plug-in type suspension hook 5 from its rear end connected to front end, its
Upper surface is a projection upwards, two inclined-planes of described projection, the gradient on its inclined-plane, front end
Gradient less than inclined-plane, rear end.
The steel ladle cover peg described in inclined-plane insertion during inserting, before horizontal plug-in type suspension hook 5
10, during horizontal movement, steel ladle cover 9 is mentioned by this inclined-plane, slips over the peak of projection
, then inclined-plane from behind slides, and plays the effect preventing steel ladle cover 9 from skidding off.
Described mechanism body 2 is arranged on described mechanism's door frame 1 by limited post framework 6, described

Vertical bar contact on 6.
Under the spacing guide effect of limited post framework 6 and directive wheel 7, hoist cylinder 4 realizes hoisting mechanism
3, the Integral synchronous of mechanism body 2 and horizontal plug-in type suspension hook 5 stably lifts.Limited post framework 6
Being welded on mechanism's door frame 1, directive wheel 7 is arranged in mechanism body 2, reaches the work of spacing guiding
With；Described horizontal plug-in type suspension hook 5 has special version and position relationship, energy and steel
Clad 9 with the use of, add a cover automatically or take off lid, can by elongation hoist cylinder 4 mention
Steel ladle cover 9, reaches the effect that ladle is not added a cover.
Described steel ladle cover 9 is provided with steel ladle cover positive stop hook 11, and described steel ladle cover positive stop hook 11 is provided with one
The individual stopper slot towards under shed；Described ladle 8 is provided with positive stop hook pin 12；Described
Under the state that steel ladle cover 9 covers described ladle 8, described stopper slot is stuck in described positive stop hook
On pin 12.When this structure makes steel ladle cover 9 promote under horizontal plug-in type suspension hook 5 acts on, do not enter
Row horizontal movement, only makees motion upwards.Otherwise steel ladle cover 9 cannot promote.
Fig. 2 is that hoist cylinder 4 extends, and covering/uncovering device is in the state promoting position, and covering/uncovering device exists
Under the effect of limited post framework 6 and directive wheel 7, to shown position after synchronizing to rise；
Fig. 3 is the top view (have rotated 90 °) of covering/uncovering device；
Fig. 4 is that ladle 8 is with cover to advance to steel ladle covering/uncovering device, and covering/uncovering device is in initial bit, behaviour
Make
Work is not required to uncovery mechanism is carried out any operation, and directly operation buggy ladle 13 travels；
Fig. 5 be steel ladle cover 9 in the driving process of buggy ladle 13, by the promotion of ladle 8, insert in level
Enter and roll on formula suspension hook 5, finally take off lid and complete as shown in the figure；
Fig. 6 is in particular cases, needs ladle not add a cover below uncovery mechanism, with satisfied steel-making
Time special process require (such as the remaining steel that gets off from continuous casting of acceptance), control covering/uncovering device
Hoist cylinder 4 promotes steel ladle cover 9.
The actual reverse process being to take off lid process of process added a cover.When ladle 8 returns, ladle 8 promotes steel
Clad 9 is pressed original route and is returned, and smoothly covers on ladle, has added a cover.
Above in conjunction with accompanying drawing, the present invention is exemplarily described, it is clear that the present invention implements not
Limited by aforesaid way, as long as have employed the method design of the present invention and technical scheme is carried out
The improvement of various unsubstantialities, or the most improved design by the present invention and technical scheme directly should
For other occasion, all within protection scope of the present invention.
