[0028] To make the objectives, technical solutions, and advantages of the present utility model clearer, the technical solutions of the present utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of them. All other implementation manners obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope protected by the present utility model.

[0029] As shown in Figures 1-6 , the present utility model provides a stopper rod mechanism for a tundish of a metallurgical casting machine, including an adjusting mechanism 2 and an electric lifting frame 1 for driving the adjusting mechanism 2 to lift and lower. A reduction motor 27 is provided on the lifting end of the electric lifting frame 1, and the rotating shaft of the reduction motor 27 is fixed to the adjusting mechanism 2. The electric lifting frame 1 is a prior art, and its principle will not be elaborated here;

[0030] Two stopper rod bodies 9 are vertically installed on the adjusting mechanism 2, and the two stopper rod bodies 9 are distributed vertically. Moreover, the adjusting mechanism 2 can interchange the positions of the two stopper rod bodies 9, so that the two stopper rod bodies 9 move in opposite directions;

[0031] The rotating shaft of the reduction motor 27 is located at the midpoint between the two stopper rod bodies 9.

[0032] As an optional implementation manner, the adjusting mechanism 2 includes a first fixing plate 3 and a second fixing plate 4. The rotating shaft of the reduction motor 27 is fixed to the first fixing plate 3 through a connecting frame 26. Two guide columns 5 are vertically fixed between the first fixing plate 3 and the second fixing plate 4. A connecting plate 6 is slidably arranged on the guide columns 5. A fixing component 10 is arranged on the connecting plate 6 for fixedly installing the stopper rod body 9. Two rotating shafts 12 are rotatably arranged at the bottom of the first fixing plate 3. A wire winding wheel 15 is fixed on the rotating shaft 12. A pulling rope is wound around the wire winding wheel 15, and the other end of the pulling rope is fixed to the connecting plate 6. Conical gears one 13 are fixed to the opposite ends of the two rotating shafts 12. A motor 11 is fixed on the first fixing plate 3. A conical gear two 14 is fixed on the output shaft of the motor 11, and the conical gear two 14 meshes with the two conical gears one 13, and the two conical gears one 13 are symmetrical;

[0033] Through the cooperation of the motor 11 with the two conical gears one 13 and the conical gear two 14, the two rotating shafts 12 and the wire winding wheels 15 can be driven to rotate in opposite directions. At that time, one of the wire winding wheels 15 winds the pulling rope, and the other wire winding wheel 15 releases the pulling rope, so that the height positions of the two stopper rod bodies 9 can be replaced.

[0034] The lower end of the stopper rod body 9 passes through the second fixing plate 4, and the stopper rod body 9 is slidably connected to the second fixing plate 4. Such a design can improve the stability of the vertical movement of the stopper rod body 9.

[0035] A counterweight 7 is arranged on the upper side of the connecting plate 6. Setting the counterweight 7 can improve the force with which the stopper body 9 plugs the drain pipe of the tundish.

[0036] A bolt one 8 is threadedly connected to the connecting plate 6, and the end of the bolt one 8 passes through the connecting plate 6 and corresponds to the surface of the guide post 5. By rotating the bolt one 8 to make the bolt one 8 support the surface of the guide post 5, the connecting plate 6 can be fixed on the guide post 5.

[0037] The fixing assembly 10 includes a fixing sleeve 22 which is fixed on the connecting plate 6. The fixing sleeve 22 is slidably arranged on the surface of the stopper body 9. Two openings are symmetrically formed in the fixing sleeve 22, and clamping plates 25 are placed in the openings. The clamping plates 25 are in clearance fit with the inner walls of the openings. An installation frame 23 is fixed on the fixing sleeve 22. Two bolt threes 24 are threadedly connected to the installation frame 23, and the opposite ends of the two bolt threes 24 are respectively rotatably connected to the back surfaces of the two clamping plates 25.

[0038] By respectively rotating the two bolt threes 24 to move the two clamping plates 25 respectively, the stopper body 9 is clamped by the clamping plates 25, thereby realizing the fixation of the stopper body 9. When the stopper body 9 needs to be replaced, the fixation of the two clamping plates 25 on the stopper body 9 is released, and the stopper body 9 can be directly pulled out of the fixing sleeve 22, making the replacement of the stopper body 9 very convenient.

[0039] The upper end of the stopper body 9 is fixedly installed with a fixing plate 21 through a bolt two 19, and the bottom of the fixing plate 21 contacts the upper side of the fixing sleeve 22. The cooperation between the fixing plate 21 and the fixing sleeve 22 can prevent the stopper body 9 from sliding downwards from the fixing sleeve 22. A hanging ring 20 is arranged on the upper side of the fixing plate 21, which is convenient for lifting the stopper body 9 upwards.

[0040] A heat insulation cover 16 is arranged on the first fixing plate 3 for covering the motor 11. A ventilation duct 17 is penetrated in the heat insulation cover 16, and a blower 18 is arranged at the end of the ventilation duct 17. The heat insulation cover 16 is provided to prevent the external high temperature from directly acting on the motor 11. The blower 18 conveys external air into the heat insulation cover 16 to cool the motor 11.

[0041] With the above structure, the electric lifting frame 1 is installed on the tundish. The height of the adjusting stopper body 9 is driven by the electric lifting frame 1. By setting two stopper bodies 9, one is in use and the other is spare. When one of the stopper bodies 9 is damaged, the adjusting mechanism 2 is rotated half a turn by the reduction motor 27, and then the upper and lower positions of the two stopper bodies 9 are replaced by the adjusting mechanism 2, so that the spare stopper body 9 can be quickly put into use. After the production stops, the damaged stopper body 9 is replaced to avoid the production being affected by the damage of the stopper body 9.

[0042] The above are only specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claimed rights.
