[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application (for ease of description and understanding, hereinafter referred to as...), Figure 2 (The above is described above). All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0019] Please see Figure 1-3 This application provides a technical solution for a stopper rod production mounting bracket: a stopper rod production mounting bracket includes a frame body 1, and a support seat 2 is provided on the bottom surface of the frame body 1.

[0020] Furthermore, the frame 1 includes side plates 16 and a bottom plate 17. The upper surface of the bottom plate 17 is provided with two side plates 16, and the upper surface of the side plates 16 is provided with not less than two threaded holes.

[0021] Furthermore, the upper surface of the support 2 is provided with a groove, and a rubber pad is provided in the groove. The groove can support the head of the stopper rod, and the rubber pad can protect the head of the stopper rod.

[0022] Two adaptive card groups 3 are provided above the support 2. The adaptive card group 3 includes a clamp 4, a mounting base 5 and a rotating shaft 6. There are two clamps 4 and two mounting bases 5. The two clamps 4 are arranged opposite each other. The front and rear ends of the clamps 4 are rotatably connected to the mounting base 5 through the rotating shaft 6. One end of the mounting base 5 is connected to the auxiliary centering group 7.

[0023] Furthermore, the clamp 4 is V-shaped, and the mounting base 5 has a groove to facilitate the rotation of the clamp 4.

[0024] The clamp 4 can rotate around the pivot 6 as the stopper is inserted, and the clamp 4 is pressed against the stopper to achieve centering. The auxiliary centering group 7 can provide locking force to the mounting base 5 and the clamp 4 so that the clamp 4 can fix the stopper.

[0025] The two lower adaptive card groups 3 are provided with auxiliary centering groups 7 between themselves and the frame 1, and the upper adaptive card group 3 is provided with an electric push rod 18 between itself and the frame 1. The electric push rod 18 can apply pressure to the adaptive card group 3, thereby facilitating the fixation of the stopper rod by the adaptive card group 3.

[0026] Furthermore, the auxiliary centering assembly 7 includes a connecting rod 8, a spring 9, a limiting block 10, and a connecting frame 11. Two connecting rods 8 are provided at one end of the mounting base 5. A spring 9 is sleeved on the outside of the connecting rod 8. One side of the spring 9 is connected to the frame 1 through the connecting frame 11. One end of the connecting rod 8 passes through the connecting frame 11 and is connected to the limiting block 10. The connecting rod 8 and the connecting frame 11 are slidably connected. The connecting frame 11 is provided with space to facilitate the movement of the limiting block 10.

[0027] Specifically, the connecting rod 8 can limit the spring 9 and provide auxiliary guidance for the mounting base 5. The spring 9 can provide locking force to the mounting base 5, which facilitates the clamp 4 to self-align the stopper rod. The connecting frame 11 can support the connecting rod 8 and the spring 9.

[0028] When the stopper rod is inserted between the two clamps 4, as the stopper rod is inserted, the clamps 4 drive the mounting base 5 and the connecting rod 8 to move towards the frame 1, and the mounting base 5 squeezes the spring 9, while the spring 9 provides a locking force to the mounting base 5.

[0029] The front and rear ends of the adaptive card group 3 are connected to the frame 1 through the guide group 12.

[0030] Furthermore, the guide assembly 12 includes a connecting plate 13, a guide rod 14, and a fixing plate 15. The front and rear ends of the mounting base 5 are provided with connecting plates 13. The guide rod 14 is vertically arranged at the upper position of the connecting plate 13, and the connecting plate 13 and the guide rod 14 are slidably connected. The two ends of the guide rod 14 are connected to the frame 1 through the fixing plate 15.

[0031] The connecting plate 13 can slide along the guide rod 14. This arrangement provides guidance for the mounting base 5 and the clamp 4, ensuring the stability of the movement of the clamp 4 and the mounting base 5.

[0032] In use: The stopper rod is hoisted above the two clamps 4 by a crane. The stopper head of the stopper rod is slowly lowered into the two clamps 4. As the stopper rod is inserted between the two clamps 4, the clamps 4 move the mounting base 5 and the connecting rod 8 toward the frame 1. The mounting base 5 compresses the spring 9, and the spring 9 provides a locking force to the mounting base 5 to ensure that the stopper rod is vertically aligned. The stopper head falls into the groove of the support 2. Then, the two electric push rods 18 move the upper adaptive clamp group 3 toward the stopper rod to fix the stopper rod. The operator can use pipe wrenches to tighten the stopper rod core. Then, the two electric push rods 18 move the two clamps 4 of the adaptive clamp group 3 away from the stopper rod. The continuous casting stopper rod with the rod core installed is hoisted to the continuous casting tundish by a crane.
