Technical Field

[0001] The utility model relates to the field of steel smelting, in particular to a cross arm structure for preventing a stopper rod from falling off. Background Art

[0002] In the continuous casting process, the stability of the mold liquid level is controlled by the opening and closing of the tundish stopper rod. The reliable connection between the stopper rod and the cross arm is the key to maintaining the stability of the liquid level and an important node to ensure smooth production. However, in the actual production process, the stopper rod often shifts and slides from the U-shaped groove of the cross arm, causing the mold liquid level to rise, resulting in production interruption.

[0018] The following is combined with Figure 1-5 , the specific implementation methods of the utility model are described in detail. The implementation methods are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model. Obviously, the embodiments described in the utility model are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the utility model.

[0019] "One embodiment" or "some embodiments" described in this specification means that one or more embodiments of the present invention include specific features, structures or characteristics described in conjunction with the embodiment. Therefore, in this specification, the terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized.

[0020] like Figure 1 , 2 As shown, the cross arm structure for preventing the stopper rod from falling off includes a stopper rod cross arm and a T-shaped component 4. A U-shaped opening groove 1 is provided at the front end of the stopper rod cross arm, and a connecting hole 3 is provided at the rear end. The connecting hole 3 is a through hole. A rectangular groove 2 is provided on the upper surface of each arm of the U-shaped opening groove 1, and the rectangular grooves are arranged opposite to each other.

[0021] like Figure 3 As shown, the T-shaped component 4 includes a longitudinal section and a transverse section, the transverse section extends outward from the middle of the longitudinal section, and the longitudinal section and the transverse section are perpendicular; a circular arc portion is provided at the head of the transverse section; and the width of the longitudinal section is slightly smaller than the width of the rectangular groove 2.

[0022] like Figure 4 As shown, the longitudinal section of the T-shaped component 4 is placed in the two rectangular grooves 2 of the two arms of the U-shaped opening groove 1, and the head of the transverse section and the groove bottom of the U-shaped opening groove 1 form a sealed annular hole 5.

[0023] like Figure 5 As shown, the rear end of the cross arm structure for preventing the stopper rod from falling off is fixedly connected to the stopper rod adjustment structure 6 through the connecting hole 3; the stopper rod 7 is inserted into the annular hole 5 formed by the head of the transverse section of the T-shaped component 4 and the bottom of the U-shaped opening groove 1, and is fastened with a nut. Since the stopper rod screw is restricted in the annular hole 5 and cannot move after being fixed, the problem of displacement and falling of the stopper rod during the production process is basically solved.

[0024] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
