Downward stopper slot 15；Gear shaping 6 upper surface being fixed on lifting support 3 front end is a projection upwards, protruding oblique by two
Face is constituted, the gradient on its inclined-plane, front end less than the gradient on inclined-plane, rear end, gear shaping 6 and the steel ladle cover positive stop hook 8 on steel ladle cover 10 and
Positive stop hook lever 9 interoperation on ladle, it is achieved ladle 11 automatically covering/uncovering operates；Device is in the state adding a cover or taking off lid
Under, gear shaping 6 rotates suspension centre 7 with steel ladle cover and contacts, and plays the effect of supporting steel clad 10, and realizes being rotationally connected.Set on ladle 11
Limited location hook lever 9, when steel ladle cover 10 covers ladle 11, stopper slot 15 is stuck on positive stop hook lever 9, prevents ladle
Lid 10 comes off；Ladle 11 is on buggy ladle 12.
When overhaul of the equipments, lay down the connector of fixed support 2 and mechanism's fixed station 1, it is achieved fixed support 2, liter descending branch
Frame 3 and lifting hydraulic cylinder 4 three keep in repair as an entirety and change.
Gear shaping 6 quantity is four, also referred to as four gear shaping structures.
The present invention is additionally provided with hydraulic power unit and the electric-control system etc. of routine.
The present invention reaches based on techniques below, is provided with four gear shapings, also referred to as four gear shaping structures before and after lifting support；
When lifting support has lifting action, lifting support is pushed down on fixed support by lifting hydraulic cylinder, during preventing uncovery
Lifting support moves vertically, by the action of lifting hydraulic cylinder, it is achieved lifting support and the integral elevating of gear shaping, gear shaping and lifting
Support synchronization action；The gear shaping upper surface being fixed on lifting support front end is a projection upwards, protruding by two inclined-plane structures
Becoming, the gradient on its inclined-plane, front end is less than the gradient on inclined-plane, rear end.With the positive stop hook on steel ladle cover and the positive stop hook lever on ladle
Interoperation, it is achieved ladle automatically covering/uncovering operates.The layout of directive wheel, limits inclination and the deflection of lifting support；Work as liter
When descending liquid cylinder pressure drives lifting support to carry out lifting action, lifting support drives gear shaping easy motion in vertical direction.Four
Gear shaping and four rotation suspension centre corresponding matching use.Gear shaping with rotate suspension centre contact, steel ladle covering/uncovering device be in add a cover or
Under the state taking off lid, the two realization is rotationally connected.Steel ladle cover is provided with clad positive stop hook, clad positive stop hook be provided with an opening to
Under stopper slot；Ladle is provided with positive stop hook lever；When steel ladle cover covers ladle, stopper slot is stuck in positive stop hook lever
On, for preventing steel ladle cover from producing landing under the influence of gravity or other factors, the rotation suspension centre on steel ladle cover is convex by gear shaping
Before the peak risen, the steel ladle cover positive stop hook on steel ladle cover has blocked with the positive stop hook lever on ladle.Ladle is by buggy ladle
It is transported to each operating position.
When taking off lid process and starting, steel ladle cover positive stop hook is stuck on positive stop hook lever, and buggy ladle drives ladle horizontal movement,
Steel ladle cover is similarly subjected to the drive of horizontal force, the contact of incline plane rotating suspension centre and gear shaping leading portion on steel ladle cover, rotates suspension centre edge
Inclined-plane rotates.In rotation process, steel ladle cover is gradually raised, and slips over the peak that front gear shaping is protruding, more sliding from the inclined-plane of back segment
Under.Due to front and back's gear shaping shape and the cooperation of position, steel ladle cover is raised to certain height, the simultaneously limit of the steel ladle cover on steel ladle cover
Position hook departs from the positive stop hook lever on ladle, and steel ladle cover rests on gear shaping, and ladle continues traveling under buggy ladle drives,
Complete to take off lid action.The actual reverse process being to take off lid of process of ladle stamp.When buggy ladle drives ladle to return, on ladle
Positive stop hook lever encounters the lower edge of the steel ladle cover positive stop hook on steel ladle cover, and under the promotion of buggy ladle, steel ladle cover is pushed away by original route
Going out gear shaping, steel ladle cover smoothly covers on ladle, completes to add a cover action.From the foregoing, due to gear shaping and steel ladle cover positive stop hook
Cooperation arrange, in course of normal operation, steel ladle covering/uncovering device need not be carried out any operation, can be achieved with ladle fortune
Automatically add a cover during row or take off lid.For meeting actual production demand, realized the lifting of gear shaping by hydraulic cylinder, thus realize not
Add a cover the requirement running the process route with operation with cover.According to the actual requirements, after lid taken off by ladle, by the action of hydraulic cylinder,
Lifting support, gear shaping, steel ladle cover rise overally, it is achieved ladle is the most with cover backhauls row on buggy ladle.After ladle stamp, pass through
The action of hydraulic cylinder, lifting support, gear shaping rise overally, it is achieved ladle is with cover backhauls row on buggy ladle.
When overhaul of the equipments, lay down the connector of fixed support and mechanism's fixed station, fixed support, lifting support and lifting
Hydraulic cylinder can keep in repair as an entirety and change, it is to avoid the on-line maintenance impact on producing.
It is an advantage of the current invention that: meet process for making to molten steel insulation, energy-saving and cost-reducing requirement, it is achieved whole-process automatic steel
Bag uncovery.Simple in construction, reliable, practical, safeguard change convenient, take few advantage in man-hour.Particularly with greatly
Tonnage ladle, energy conservation and consumption reduction effects becomes apparent from.
