[0031] This embodiment provides a ladle cover for molten iron, see reference. Figures 1-5As shown, the lower part of the cover 1 is provided with a body 2, one end of the cover 1 is rotatably connected with the body 2 through a first rotating shaft 3, the side edge of the body 2 is connected with a support plate 21, the upper end of the support plate 21 is provided with a sleeve 4, the sleeve 4 is sleeved with a push rod 41, the bottom end of the sleeve 4 is provided with a second rotating shaft 42, one end of the second rotating shaft 42 outside the sleeve 4 is connected with one end of a support rod 5, the other end of the second rotating shaft 42 is connected with one end of a cam 421, the bottom end of the push rod 41 is in contact with the cam 421, the upper end of the push rod 41 is in contact with the outer edge of the cover 1, the two side edges of the body 2 are rotatably connected with the bottom end of a hanger 6 through a third rotating shaft 11, the side edge of the third rotating shaft 11 is connected with a driving rotating wheel 112 through a connecting rod 111.

[0032] In the above embodiment, the body 2 is filled with high-temperature molten iron, the cover 1 covers the upper part of the body 2, the side edge of the body 2 is connected with the support plate 21, and the upper end of the support plate 21 is provided with the sleeve 4, the sleeve 4 is sleeved with the push rod 41, the push rod 41 moves up and down in the vertical direction of the sleeve 4, the bottom end of the sleeve 4 is provided with the second rotating shaft 42, the second rotating shaft 42 is rotatably installed at the bottom end of the sleeve 4, that is, the second rotating shaft 42 can rotate at the bottom end of the sleeve 4, and one end of the second rotating shaft 42 outside the sleeve 4 is connected with one end of the support rod 5, the other end of the second rotating shaft 42 is connected with one end of the cam 421. Figure 2 、 Figure 5 For example, when the support rod 5 is pulled down, the support rod 5 drives the second rotating shaft 42 to rotate, because the second rotating shaft 42 is connected with one end of the cam 421, that is, the second rotating shaft 42 drives one end of the cam 421 to rotate, so that the other end of the cam 421 is deflected upward, the bottom end of the push rod 41 in the sleeve 4 is in contact with the cam 421, the other end of the cam 421 is deflected upward, the vertical height of the protruding end is increased, thereby pushing the push rod 41 to move upward, the upper end of the push rod 41 is in contact with the outer edge of the cover 1, the push rod 41 moves upward, thereby pushing the cover 1 to move upward, so that an opening is formed between the cover 1 and the body 2, and the slag can be poured out from the opening. Similarly, the support rod 5 is pushed back, the protruding end of the other end of the cam 421 is deflected downward, the height is reduced, and under the action of gravity, the cover 1 presses the push rod 41 to move downward, and the opening between the cover 1 and the body 2 is closed. The lever principle is used, the second rotating shaft 42 is used as a lever fulcrum, and the rotating arm of the support rod 5 is much larger than the rotating arm of the cam 421, so that the force of pulling the support rod 5 by the worker produces a deflection force relative to the cam 421, which plays a role of lever amplification, so that the worker opens the cover 1 more easily, improves the convenience of opening the cover 1, improves the production efficiency, and the worker can be relatively far away from the ladle when pulling the support rod 5, so as to prevent the molten iron in the ladle from splashing and contacting the body to cause burns, thereby ensuring the health and safety of the worker.

[0033] In an embodiment of the present application, referring to Figure 5 The bottom end of the push rod 41 is provided with a pulley 411.

[0034] In the above embodiment, when the cam 421 pushes the push rod 41 upward, the bottom end of the push rod 41 will slide with the outer surface of the cam 421, on the one hand, the repeated sliding friction will cause the contact surface between the bottom end of the push rod 41 and the outer surface of the cam 421 to wear, causing damage to the parts, on the other hand, more force needs to be applied to the support rod 5 to overcome the friction, by providing a pulley 411 at the bottom end of the push rod 41, by the contact between the pulley 411 and the cam 421, the sliding friction is converted into rolling friction, to reduce the friction between the bottom end of the push rod 41 and the cam 421, prevent parts from wearing, improve the service life of the parts, make the process of opening the cover 1 more labor-saving.

[0035] In an embodiment of the present application, referring to Figure 1 、 Figure 5 The second rotating shaft 42 is connected with a plug pipe 422 on the outer side of one end of the sleeve 4, and the support rod 5 is inserted into the plug pipe 422.

[0037] In an embodiment of the present application, the outer surface of the support rod 5 and the driving wheel 112 is coated with a heat insulation layer.

[0038] In the above embodiment, the outer surface of the support rod 5 and the driving wheel 112 is coated with a heat insulation layer, which is used to prevent the high temperature of molten iron from being conducted through the support rod 5 and the driving wheel 112, causing burns after contact by the operator, and the heat insulation material can be aluminum silicate fiber.

[0039] In an embodiment of the present application, referring to Figure 1 The upper end side of the package body 2 is provided with a package mouth 7.

[0040] In the above embodiment, the package mouth 7 plays a role in guiding the flow of molten iron out of the package body 2, avoiding that the flow area is too large when the package body 2 pours molten iron, which is easy to cause the molten iron to flow too fast, causing splashing of the molten iron, resulting in waste of raw materials, or burning damage to equipment and personnel.

When the support rod 5 is pulled down, the support rod 5 drives the second rotating shaft 42 to rotate, because the second rotating shaft 42 is connected with one end of the cam 421, that is, the second rotating shaft 42 drives one end of the cam 421 to rotate, so that the other protruding end of the cam 421 deflects upward, the bottom end of the push rod 41 in the sleeve 4 is in contact with the cam 421, the other end of the cam 421 deflects upward, the vertical height of the protruding end increases, and the push rod 41 is pushed upward, the upper end of the push rod 41 abuts against the outer edge of the cover 1, the push rod 41 moves upward and pushes the cover 1 upward, so that an opening is formed between the cover 1 and the ladle 2, and the slag can be poured out from the opening. Further, the two side edges of the ladle 2 are rotatably connected with the bottom end of the hanger 6 through the third rotating shaft 11, the hanger 6 is used for lifting the ladle, and is convenient for transferring between different production stations. In addition, the side edge of the third rotating shaft 11 is connected with the driving rotating wheel 112 through the connecting rod 111, and the third rotating shaft 11 is driven to deflect and tilt the ladle 2 by rotating the driving rotating wheel 112, so as to pour out the slag from the opening between the ladle 2 and the cover 1. The driving rotating wheel 112 can also be used for adjusting the posture of the ladle 2, so that the initial state of the ladle 2 remains vertical, thereby improving the stability of the ladle 2.
