Description
Technical field
The utility model belongs to the heat-preserving equipment technical field for Molten Iron Transportation in engineer equipment, is specifically related to the safe vehicle-mounted ladle in a kind of Molten Iron Transportation process.
Background technology
At present, by molten iron from blast furnace be transported to converter still be opened type ladle.As everyone knows, iron ore smelting is needed the at substantial energy for liquid molten iron.But, in steel mill, the spacing of blast furnace and converter is often comparatively far away, not at a factory building, molten iron opened type ladle is transported to converter from blast furnace and will inevitably causes constantly heat exchange occurring between molten iron and air, cause molten iron charging temperature to reduce, ultimately increase steel-making cost.And very easily there is security incident at sleety weather opened type molten iron contracted affreightment molten iron.The volume of smoke distributed in Molten Iron Transportation process also to environment, can affect the service life of relevant device simultaneously.Therefore it is a kind of imperative with adding the ladle of getting lid arrangement to design.
Up to the present, can realizing ladle, to add the device getting lid little, and the space that these devices take is all relatively large.But existing most of steel plant, hall space is crowded all especially, and during design, headspace is less, so require that adding the device getting lid to ladle wants to complete and get lid action to adding of ladle in the very little space of regulation.And steel plant are in order to improve steel-making efficiency, the molten iron transportation vehicle of design is all to be interconnected as railway carriage, conveniently drags multiple ladle simultaneously.This present situation requires ladle to add to get that lid arrangement will complete in less spatial dimension and gets lid action to adding of ladle, otherwise can produce collision, causes security incident.Concrete with reference to shown in Fig. 2, Fig. 2 is two molten iron transportation vehicle connection diagrams, have body of wall to limit above molten iron transportation vehicle, intersecting net region in figure is reserved safe space, prevents from the ladle on two molten iron transportation vehicles from adding getting lid arrangement mutually to collide adding to get in lid process.In addition, the ladle surrounding environment that molten iron is housed is severe, requires to add that to get lid arrangement simple and practical, high temperature resistant.Existing adding, gets lid arrangement and is difficult to meet these requirements, so research and develop the less ladle of a kind of more safe and reliable requisite space to add that to get lid arrangement be very necessary and urgent.
Utility model content
The utility model provides a kind of in very little safe space, completes the safe vehicle-mounted ladle adding and get lid action.
The utility model adopts following technical scheme:
1. a safe vehicle-mounted ladle, comprise: be located at the ladle on molten iron transportation vehicle and molten iron clad, it is characterized in that, guiding rocking bar is provided with between molten iron transportation vehicle and molten iron clad, and one end of guiding rocking bar and molten iron transportation vehicle are rotationally connected, the other end and the molten iron clad of guiding rocking bar are rotationally connected, cover in ladle and be rotatably connected to scalable rocking bar, the sliding sleeve that described scalable rocking bar comprises slide bar and is connected with sliding bar, one end and the molten iron clad of described slide bar are rotationally connected, the other end of slide bar and one end of sliding sleeve are slidably connected, the other end and the molten iron transportation vehicle of sliding sleeve are rotationally connected, Electrohydraulic push rod is provided with between sliding sleeve and molten iron transportation vehicle, piston rod and the sliding sleeve of Electrohydraulic push rod are rotationally connected, piston cylinder and the molten iron transportation vehicle of Electrohydraulic push rod are rotationally connected, auxiliary rotary bar is provided with between slide bar and molten iron transportation vehicle, one end and the slide bar of auxiliary rotary bar are rotationally connected, the other end and the molten iron transportation vehicle of auxiliary rotary bar are rotationally connected, between auxiliary rotary bar and molten iron transportation vehicle be rotationally connected a little between sliding sleeve and molten iron transportation vehicle be rotationally connected a little and between ladle.
Described slide bar comprises axle, steel plate and steel plate with holes, described axle and steel plate are connected, axle is provided with high temperature resistant bearing, described steel plate with holes is provided with installing hole, described high temperature resistant bearing is through the inwall Structure deformation of installing hole and sliding sleeve, described steel plate is provided with the first external arc projection and the second external arc projection, and described sliding sleeve is provided with Inner arc projection.
Molten iron transportation vehicle is respectively equipped with the first pedestal and the second pedestal, and described sliding sleeve is by realizing and the rotation of molten iron transportation vehicle with being rotationally connected of the first pedestal, and described auxiliary rotary bar is by realizing and the rotation of molten iron transportation vehicle with being rotationally connected of the second pedestal.
Compared with prior art, the utility model tool has the following advantages:
The utility model devises a kind of with adding the vehicle-mounted ladle of getting lid arrangement, achieve and get lid motion to adding of the ladle in transport molten iron process, compare with opened type ladle, effectively reduce the heat loss in Molten Iron Transportation process, reduce steel-making cost.And smoke contaminations a large amount of in Molten Iron Transportation process can be avoided, prolongation relevant device is played a role service life.
The more important thing is, the utility model utilizes multi-bar linkage to solve the problem of getting safely lid in less space to ladle.When Electrohydraulic push rod shrinks, slide bar is under the drive of sliding sleeve and auxiliary rotary bar, slip into sliding sleeve gradually, the scalable rocking bar total length of slide bar and sliding sleeve composition is constantly reduced, thus change the fall trajectory of molten iron clad, avoid molten iron clad to enter in Fig. 2 intersecting the reserved safe space of grid region representation, thus avoid ladle to get in lid process with adjacent molten iron clad and get lid arrangement and collide, interfere.In slide bar, be provided with high temperature resistant bearing, high temperature resistant bearing through installing hole and sliding sleeve Structure deformation, thus reduces the resistance of motion of slide bar in sliding sleeve, and scalable rocking bar can normally be stretched.
Slide bar is provided with two external arc projections, sliding sleeve is provided with Inner arc projection, do like this and the displacement of slide bar in sliding sleeve can be limited between the first external arc projection and the second external arc projection, when preventing Electrohydraulic push rod to lose efficacy, the free falling of molten iron clad causes security incident.
Therefore, to get in lid process in good time flexible adding by the scalable rocking bar of slide bar, sliding sleeve composition for the utility model, realize farthest reducing to add getting lid arrangement motion requisite space, thus can be implemented in and drag multiple ladle in transport molten iron process simultaneously and do not collide, improve space availability ratio, improve steel-making efficiency.The existing cap taking mechanism that adds is not provided with so scalable rocking bar, completes to add to get to cover the space needed for moving comparatively greatly, if drag two molten iron transportation vehicles simultaneously, adds and gets in lid process security incidents such as very easily colliding.And of the present utility model adding get lid arrangement, structure is simple, and reliability is high, can at high temperature safely and steadily run.In addition, in the utility model, the Telescopic of scalable rocking bar is completed by pure machine driven system, do not need additional motive power, economical and practical.
