In the embodiment, a 140 ton molten iron car is taken as an example, the car length is 9590mm, the width is about 3200mm, the height from the mouth of a molten iron tank to the rail surface is about 4900mm, the lowest part of the floor of a molten iron tank loading area is 5200mm, a movable height space is covered by 300mm, and the thickness of a cover plate is 100mm, so that the vertical height range of the cover plate when the cover plate is opened and closed is required to be within 200 mm; in addition, the width of two lifting lugs of the hot-metal ladle is 4760mm, the length of the ladle car is 9590mm, and the horizontal movement space of two sides of the cover plate after the cover plate is horizontally moved away from the edge of the ladle body is 700mm, so that the movable space of the ladle body lifting appliance can only be increased by the flip. By combining the environmental conditions, the moving mode and track of the hot metal ladle cover plate need to be optimized.

Referring to fig. 1 and 2, the present preferred embodiment provides a hot metal ladle capping device, which includes a frame 1 and a hot metal ladle body 2 disposed on the frame 1, wherein support seats 3 are respectively disposed on two sides of the frame 1 and located on the hot metal ladle body 2, and a first driving cylinder 4 and a swing arm mechanism are disposed on the support seats 3.

The swing arm mechanism comprises a first supporting rod 5 and a second supporting rod 6, the first driving cylinder 4 drives the first supporting rod 5 or the second supporting rod 6, the first supporting rod 5 and the second supporting rod 6 are arranged side by side and are linked through a connecting rod 7, one end of the first supporting rod 5 is hinged to the supporting seat 3, the other end of the first supporting rod 5 is hinged to the half cover plate 8, one end of the second supporting rod 6 is hinged to the supporting seat 3, the other end of the second supporting rod 6 is hinged to the half cover plate 8, the second driving cylinder 9 is mounted in the middle section of the second supporting rod 6, the second driving cylinder 9 is used for adjusting the length of the second supporting rod 6, the half cover plates 8 on two sides are matched to act, and a closed cover and an opened cover are formed on the hot metal ladle tank body 2.

Specifically, two groups of swing arm mechanisms are arranged on each side of the supporting seat 3, and the first supporting rods 5 in the two groups of swing arm mechanisms are connected and linked through the cross rod 10.

Specifically, in the switching process of the closing state and the opening state, the stroke of the second driving cylinder 9 is zero, the effective lengths of the first supporting rod 5 and the second supporting rod 6 are equal, and the half cover plate 8 is always kept horizontal according to the parallelogram linkage mechanism principle.

On the basis, when the cover is opened, the second support rod 6 continues to be driven by the second driving cylinder 9 to stretch and retract relative to the first support rod 5, so that the half cover plate 8 can be overturned and stored, and the lifting space is further enlarged.

Particularly, a limit seat 11 for limiting the cross rod 10 is arranged on the frame 1 and is used for limiting the uncapping action limit and ensuring the swing arm mechanism to act in a safety range.

Considering that the second support rod 6 is an assembly compared with the first support rod 5, preferably, the second support rod 6 is located at the outer side of the first support rod 5, so that the second driving cylinder 9 is far away from the hot-metal ladle tank body 2, one end of the second driving cylinder 9 is in flange connection with a rod section of the second support rod 6, and the other end of the second driving cylinder 9 is hinged with the rod section of the second support rod 6. Further, the heat insulation sleeve is arranged outside the second driving cylinder 9, so that the normal use of the mechanism is prevented from being influenced by the high temperature condition of the hot metal ladle.

In particular, in order to reduce the motion amplitude of the swing arm mechanism, the first support rod 5 and the second support rod 6 are bent inwards, the first driving cylinder 4 is located on the outer side of the second support rod 6, and two ends of the first driving cylinder 4 are hinged with the support seat 3 and the second support rod 6 respectively.

The first and second drive cylinders 4 and 9 are preferably cylinders, and the frame 1 is provided with a hydraulic station 12, and the hydraulic station 12 is connected to the first and second drive cylinders 4 and 9 through pipes, respectively.

Therefore, when the cover is closed and opened, the half cover plates 8 keep the horizontal state according to the parallelogram link mechanism principle, and move along a large-radius gentle arc track, so that the two half cover plates 8 move up and down while opening and closing, and the requirement on space is reduced.

In the process of uncovering, see fig. 3 in detail, when the half cover plate 8 translates along the circular arc track, the half cover plate 8 is raised to the highest point, and then moves down while translating, in the design, when the half cover plate 8 moves to the highest point, the half cover plate 8 moves upwards by 118.5mm compared with the tank opening, and is controlled within the limit height range of 200mm, so that the complete opening and closing action can be realized.

Conversely, when the two half cover plates 8 are closed in a centering way, the cover plates move downwards to fall on the tank opening.

In the process of turning over the cover, see fig. 4 in detail, when the half cover plate 8 translates to about 420mm from the outer wall of the ladle body 2, the first driving cylinder 4 stops working, the second driving cylinder 9 starts, the half cover plate 8 turns over downwards with an inner supporting point to move to the lowest position, the hoisting space is opened as much as possible, the front edge of the cover plate is 600mm away from the space between the lifting lugs of the ladle body, and the ladle car is convenient to hoist.

In summary, the hot metal ladle capping device realizes that the two half cover plates are kept in a horizontal state in the capping and uncapping processes, and move along a large-radius gentle arc track, so that the hot metal ladle is tightly covered to achieve the best heat preservation effect, meanwhile, the movable space of the mechanism and the half cover plates during uncapping is reduced as much as possible, the requirement on the field space is reduced, and the hot metal ladle car is convenient to use.
