Description

Technical Field

[0001] This application belongs to the field of fixture technology, and in particular relates to an immersion sprue fixture. Background Technology

[0002] Submerged entry nozzles for continuous casting are key components used in the continuous casting process to protect the molten steel flow, prevent secondary oxidation of the molten steel, and regulate the flow state and injection speed of the molten steel. They are installed at the bottom of the tundish and inserted below the molten steel surface in the crystallizer. Refined molten steel is continuously injected into the crystallizer through its internal channels. To prevent abnormal damage to the submerged entry nozzle during use, it is necessary to bake the spare nozzle.

[0003] Submersible nozzles are cast from refractory materials. During use, problems such as turbulence and leakage often occur, necessitating replacement with new nozzles. However, submersible nozzles must be heated by flame before use. Replacing such high-temperature nozzles requires specialized clamps for installation.

[0004] In related technologies, the immersion nozzle clamp is a hydraulic clamp, which is equipped with components such as hydraulic cylinders, oil pipes, and oil pumps. Hydraulic clamps are heavy and limited by oil pipes, and are inconvenient to move. Utility Model Content

[0013] The fourth limiting part and the fifth limiting part are arranged opposite to each other, and the fourth limiting part and the fifth limiting part are both arranged at an angle to the sixth limiting part, so that the fourth limiting part, the fifth limiting part and the sixth limiting part together form the first clamping groove;

[0014] The third limiting part is disposed opposite to the sixth limiting part, the second limiting part is disposed opposite to the fifth limiting part, and the first limiting part is disposed opposite to the fourth limiting part, so that the clamping area is formed between the third limiting part and the sixth limiting part.

[0015] In some embodiments, the first clamping member includes a support arm portion, a connecting portion, and a first clamping portion. The support arm portion and the first clamping portion are respectively located on both sides of the connecting portion. The connecting portion is connected to the support arm portion and the first clamping portion. The support arm portion and the first clamping portion are disposed opposite to each other.

[0016] In some embodiments, the first clamping assembly further includes a force-applying element, which is fixedly connected to the connecting rod on the side away from the first clamping assembly.

[0017] In some embodiments, the force-applying member includes a first gripping portion, a second gripping portion, and a gripping portion connecting portion. The middle portion of the gripping portion is fixedly connected to the connecting rod.

The rotating rod is rotatably connected to the connecting rod, and the sliding rod is slidably connected to the connecting rod along the length of the connecting rod. With this design, rotating the rotating member drives the rotating rod to rotate, allowing the rotating rod to extend and retract along the length of the connecting rod. The sliding rod is rotatably connected to the rotating rod and slidably connected to the connecting rod, so the sliding rod can extend and retract with the rotating rod without rotating.

[0047] This application is described below with reference to the accompanying drawings and specific embodiments:

[0048] like Figures 1 to 7 As shown, the immersion nozzle clamp 100 is used to clamp the immersion nozzle, and the immersion nozzle clamp 100 includes a first clamping component 110 and a second clamping component 120.

[0049] The first clamping assembly 110 includes a connecting rod 111 and a first clamping member 112 fixedly connected to one side of the connecting rod 111.

[0050] The second clamping assembly 120 includes a rotating member 121, a rotating rod 122, a sliding rod 124, and a second clamping member 123. One side of the rotating rod 122 is rotatably connected to one side of the sliding rod 124. The rotating rod 122 is partially located inside the connecting rod 111 and is threadedly connected to the connecting rod 111. The sliding rod 124 is partially located inside the connecting rod 111. Along the length direction of the connecting rod 111, the sliding rod 124 is slidably connected to the connecting rod 111. The rotating member 121 is fixedly connected to the side of the rotating rod 122 away from the sliding rod 124. The second clamping member 123 is fixedly connected to the side of the sliding rod 124 away from the rotating rod 122.

[0051] The first clamping member 112 and the second clamping member 123 form a clamping area 100a for clamping the immersion nozzle. When the rotating member 121 is rotated, the second clamping member 123 can move closer to the first clamping member 112 or move away from the second clamping member 123.

[0052] One side of the rotating rod 122 is rotatably connected to one side of the sliding rod 124, and the other side of the rotating rod 122 is fixedly connected to the rotating component 121. The other side of the sliding rod 124 is fixedly connected to the second clamping component 123. A through hole is provided on the connecting rod 111. The side of the rotating rod 122 near the sliding rod 124 is located inside the connecting rod 111 and is threadedly connected to the inner wall of the connecting rod 111. The side of the sliding rod 124 near the rotating rod 122 is located inside the connecting rod 111, and the sliding rod 124 is slidably connected to the connecting rod 111 along the length of the connecting rod 111.

[0053] With this configuration, the user can rotate the rotating component 121 to drive the rotating rod 122 to rotate. Since the rotating rod 122 is threadedly connected to the connecting rod 111, it will extend and retract along the length of the connecting rod 111 while rotating. Because the sliding rod 124 is rotatably connected to the rotating rod 122 and slidably connected to the connecting rod 111, it will not rotate with the rotating rod 122; instead, it will only slide along the connecting rod 111. Since the second clamping member 123 is fixed to the sliding rod 124, it will move synchronously with the sliding rod 124, allowing it to move towards or away from the first clamping member 112.

[0054] When the rotating member 121 drives the rotating rod 122 to rotate clockwise, the second clamping member 123 moves toward the first clamping member 112. When the rotating member 121 drives the rotating rod 122 to rotate counterclockwise, the second clamping member 123 moves away from the first clamping member 112.

[0055] Alternatively, when the rotating member 121 drives the rotating rod 122 to rotate counterclockwise, the second clamping member 123 moves toward the first clamping member 112; when the rotating member 121 drives the rotating rod 122 to rotate clockwise, the second clamping member 123 moves away from the first clamping member 112.

[0056] With this design of the present application, rotating the rotating member 121 can drive the first clamping member 112 to move, so as to clamp the submerged nozzle located between the first clamping member 112 and the second clamping member 123, or release the submerged nozzle located between the first clamping member 112 and the second clamping member 123. The structure of the submerged nozzle clamp 100 is simple and the operation is convenient. Moreover, components such as hydraulic cylinders and oil pipes do not need to be designed on the submerged nozzle clamp 100 of the present application, and its movement is not restricted by the positions of oil pipes, hydraulic cylinders, etc., and its movement is more convenient.

[0057] As Figure 5 shown, in some embodiments, a threaded groove 111b is provided on the inner wall of the connecting rod 111, and an external thread 1222 is provided on the outer wall of the rotating rod 122. The external thread 1222 is located in the threaded groove 111b, so that the connecting rod 111 is threadedly connected to the rotating rod 122.

[0058] As Figure 6 shown, in some embodiments, a convex portion 1221 is provided at one end of the rotating rod 122 close to the sliding rod 124. The cross section of the convex portion 1221 is "convex"-shaped; a limiting groove 124a is provided on the end surface of the sliding rod 124 close to the connecting rod 111, and the cross section of the limiting groove 124a is also "convex"-shaped. The convex portion 1221 is located in the limiting groove 124a and is limited by the limiting groove 124a, and the convex portion 1221 cannot escape from the limiting groove 124a. Under the drive of the rotating rod 122, the convex portion 1221 can rotate in the limiting groove 124a, but since the convex portion 1221 is limited by the limiting groove 124a, the sliding rod 124 can slide along the length direction of the connecting rod 111 synchronously with the rotating rod 122.

[0059] As Figure 7 shown, in some embodiments, a guiding groove 111a extending along the length direction of the connecting rod 111 is provided on the inner wall of the connecting rod 111, and a sliding protrusion 1241 is provided on the outer wall of the sliding rod 124. The sliding protrusion 1241 is located in the guiding groove 111a, so that the sliding rod 124 can slide along the length direction of the connecting rod 111.

[0060] The structure of the rotating member 121 is diverse and is not limited in the present application. Setting the rotating member 121 can facilitate the user to rotate the rotating rod 122.

[0061] In some embodiments, the rotating member 121 is a handwheel, and the handwheel is coaxially arranged with the rotating rod 122.

[0062] The structure of the handwheel is well-known to those skilled in the art, and the handwheel can be directly purchased on the market and will not be elaborated here. As Figure 2As shown, in some embodiments, the second clamping member 123 includes a first limiting part 1231, a second limiting part 1232, and a third limiting part 1233. The first limiting part 1231 and the second limiting part 1232 are respectively located on both sides of the third limiting part 1233. The third limiting part 1233 is connected to the first limiting part 1231 and the second limiting part 1232. The third limiting part 1233 is fixedly connected to the side of the sliding rod 124 away from the rotating rod 122. The first limiting part 1231 and the second limiting part 1232 are arranged opposite to each other, and both the first limiting part 1231 and the second limiting part 1232 are arranged at an angle with the third limiting part 1233, so that the first limiting part 1231, the second limiting part 1232, and the third limiting part 1233 surround and form a second clamping groove 123a.

[0063] Specifically, the first limiting part 1231 and the second limiting part 1232 are spaced apart along the length direction of the third limiting part 1233 and are located on both sides of the third limiting part 1233. The first limiting part 1231 and the second limiting part 1232 are both fixedly connected to the third limiting part 1233.

[0064] The included angle can be a right angle, an obtuse angle, or an acute angle. In some embodiments, the first limiting part 1231 and the third limiting part 1233 are set at an obtuse angle, and the second limiting part 1232 and the third limiting part 1233 are also set at an obtuse angle, such as... Figure 2 As shown.

[0065] The first limiting part 1231, the second limiting part 1232, and the third limiting part 1233 together form a second clamping groove 123a. When clamping the immersion nozzle, the immersion nozzle portion is located in the second clamping groove 123a, and the immersion nozzle abuts against the third limiting part 1233. The first limiting part 1231 and the second limiting part 1232 limit the immersion nozzle to prevent it from coming off the third limiting part 1233.

[0066] like Figure 2As shown, in some embodiments, the first clamping member 112 includes a fourth limiting part 1121, a fifth limiting part 1122, and a sixth limiting part 1123. The fourth limiting part 1121 and the fifth limiting part 1122 are respectively located on both sides of the sixth limiting part 1123, and the sixth limiting part 1123 is connected to the fourth limiting part 1121 and the fifth limiting part 1122. The fourth limiting part 1121 and the fifth limiting part 1122 are arranged opposite to each other, and both the fourth limiting part 1121 and the fifth limiting part 1123 are connected to the sixth limiting part 1123. The six limiting portions 1123 are arranged at an angle so that the fourth limiting portion 1121, the fifth limiting portion 1122 and the sixth limiting portion 1123 surround and form the first clamping groove 112a; the third limiting portion 1233 is arranged opposite to the sixth limiting portion 1123, the second limiting portion 1232 is arranged opposite to the fifth limiting portion 1122, and the first limiting portion 1231 is arranged opposite to the fourth limiting portion 1121 so that a clamping area 100a is formed between the third limiting portion 1233 and the sixth limiting portion 1123.

[0067] Specifically, the fourth limiting part 1121 and the fifth limiting part 1122 are spaced apart along the length direction of the sixth limiting part 1123 and are located on both sides of the sixth limiting part 1123. The fourth limiting part 1121 and the fifth limiting part 1122 are both fixedly connected to the sixth limiting part 1123.

[0068] The included angle can be a right angle, an obtuse angle, or an acute angle. In some embodiments, the fourth limiting part 1121 and the sixth limiting part 1123 are set at an obtuse angle, and the fifth limiting part 1122 and the sixth limiting part 1123 are also set at an obtuse angle, such as... Figure 2 As shown.

[0069] The fourth limiting part 1121, the fifth limiting part 1122, and the sixth limiting part 1123 together form the first clamping groove 112a. Since the third limiting part 1233 is arranged opposite to the sixth limiting part 1123, the second limiting part 1232 is arranged opposite to the fifth limiting part 1122, and the first limiting part 1231 is arranged opposite to the fourth limiting part 1121, the first clamping groove 112a and the second clamping groove 123a are also arranged opposite to each other.

[0070] When clamping the submersible nozzle, part of the nozzle is located in the second clamping groove 123a and part is located in the first clamping groove 112a. The nozzle abuts against the third limiting part 1233 and also against the sixth limiting part 1123. Under the clamping action of the third limiting part 1233 and the sixth limiting part 1123, the nozzle is fixed. The first limiting part 1231, the second limiting part 1232, the fourth limiting part 1121 and the fifth limiting part 1122 all limit both sides of the nozzle to prevent it from coming off the third limiting part 1233 and the sixth limiting part 1123.

[0071] In some embodiments, the first clamping member 112 includes a support arm 1124, a connecting portion 1125, and a first clamping portion 1126. The support arm 1124 and the first clamping portion 1126 are respectively located on both sides of the connecting portion 1125. The connecting portion 1125 is connected to the support arm 1124 and the first clamping portion 1126. The support arm 1124 and the first clamping portion 1126 are arranged opposite to each other. The support arm 1124 is fixedly connected to the connecting rod 111. The first clamping portion 1126 is arranged opposite to the second clamping member 123. The sixth limiting portion 1123 is fixedly connected to the first clamping portion 1126.

[0072] Specifically, the length direction of the support arm 1124 is perpendicular to the length direction of the connecting rod 111. One side of the support arm 1124 is fixedly connected to the peripheral wall of the connecting rod 111, and the other side of the support arm 1124 is fixedly connected to one side of the connecting part 1125. The length direction of the connecting part 1125 is parallel to the length direction of the connecting rod 111, and the length direction of the first clamping part 1126 is perpendicular to the length direction of the connecting rod 111. One side of the first clamping part 1126 is fixedly connected to the other side of the connecting part 1125. Figure 2 As shown, the support arm 1124, the connecting part 1125, and the first clamping part 1126 form a "C" shaped structure.

[0073] The “C” shaped structure design avoids the second clamping member 123, the fourth limiting part 1121, the fifth limiting part 1122 and the sixth limiting part 1123, which facilitates the installation of the second clamping member 123, the fourth limiting part 1121, the fifth limiting part 1122 and the sixth limiting part 1123.

[0074] With this design, the third limiting part 1233 of the second clamping member 123 can be perpendicular to the sliding rod 124, and the middle part of the third limiting part 1233 can be fixedly connected to the sliding rod 124 without interfering with the connecting part 1125.

[0075] In some embodiments, the first clamping assembly 110 further includes a force-applying member 113, which is fixedly connected to the connecting rod 111 on the side away from the first clamping member 112.

[0076] Once the submersible nozzle is held by the submersible nozzle clamp 100, the user needs to move the submersible nozzle clamp 100 so that the submersible nozzle can be transferred to the designated position.

[0077] To facilitate the application of force by the user, these embodiments are provided with a force-applying component 113. When moving the immersion nozzle clamp 100, the user can hold the force-applying component 113 and apply force to it, which makes it easier for the user to move the immersion nozzle clamp 100.

[0078] The structure of the force-applying component 113 is varied. It can be a rope that allows the operator to apply force, or a rod that is fixed to the connecting rod 111 and perpendicular to the connecting rod 111. Silicone anti-slip sleeves can be fitted on both ends of the rod for easy gripping.

[0079] like Figure 1 As shown, in some embodiments, the force-applying member 113 includes a first gripping part 1131, a second gripping part 1132, and a gripping part connecting part 1133. The middle part of the gripping part connecting part 1133 is fixedly connected to the connecting rod 111. The first gripping part 1131 and the second gripping part 1132 are respectively located on both sides of the gripping part connecting part 1133. The connecting part 1125 is connected to the first gripping part 1131 and the second gripping part 1132. The gripping part connecting part 1133 is perpendicular to the connecting rod 111, and the first gripping part 1131 and the second gripping part 1132 are both parallel to the connecting rod 111.

[0080] Specifically, the first gripping part 1131 and the second gripping part 1132 are located at both ends of the gripping part connecting part 1133 along its length, and the first gripping part 1131 and the second gripping part 1132 are arranged opposite to each other. Both the first gripping part 1131 and the second gripping part 1132 are fixedly connected to the gripping part connecting part 1133.

[0081] With this design, when moving the submersible nozzle clamp 100, the operator's hands can respectively hold the first gripping part 1131 and the second gripping part 1132, and the operator can apply force to the submersible nozzle clamp 100 with both hands, making the submersible nozzle clamp 100 less prone to swinging.

[0082] like Figure 1 As shown, in some embodiments, the immersion nozzle clamp 100 further includes a force-applying rod 130, the force-applying rod 130 and the connecting rod 111 are respectively located on both sides of the first clamping member 112, and the force-applying rod 130 is parallel to the connecting rod 111, and the side of the force-applying rod 130 near the first connecting member is fixedly connected to the first clamping member 112.

[0083] like Figure 1 As shown, the force-applying rod 130 is located on the front side of the first clamping member 112, and the connecting rod 111 is located on the rear side of the connecting member. With this design, one operator stands on one side of the force-applying member 113 and applies force to the connecting rod 111 or the force-applying member 113, while another operator stands on one side of the force-applying rod 130 and applies force to the force-applying rod 130. The submersible nozzle is located between the connecting rod 111 and the force-applying rod 130, which helps to ensure the balance of movement of the submersible nozzle clamp 100 and the submersible nozzle on it, and facilitates the movement of the submersible nozzle clamp 100 and the submersible nozzle on the submersible nozzle clamp 100 by the user.

[0084] In some embodiments, the force-applying rod 130 and the connecting rod 111 are coaxially arranged.

[0085] In some embodiments, the immersion nozzle clamp 100 further includes a first gripping rod 140, a second gripping rod 150, and a gripping rod connecting rod 160. The middle part of the gripping rod connecting rod 160 is fixedly connected to the force-applying rod 130, and the gripping rod is perpendicular to the force-applying rod 130. The first gripping rod 140 and the second gripping rod 150 are respectively located on both sides of the gripping rod connecting rod 160. The gripping rod connecting rod 160 is connected to the first gripping rod 140 and the connecting rod 111. Both the first gripping rod 140 and the second gripping rod 150 are set at an angle to the force-applying rod 130.

[0086] The angle setting can be a right angle, an obtuse angle, or an acute angle. The first gripping rod 140 and the second gripping rod 150 are arranged opposite each other and are respectively set on both sides of the gripping rod connecting rod 160. Both the first gripping rod 140 and the second gripping rod 150 are fixedly connected to the connecting rod 111.

[0087] With this design, when moving the immersion nozzle clamp 100, the operator can hold the first gripping rod 140 and the second gripping rod 150 with both hands respectively, and the operator can apply force to the immersion nozzle clamp 100 with both hands, making the immersion nozzle clamp 100 less prone to swaying.

[0088] In some embodiments, both the first gripping rod 140 and the second gripping rod 150 are parallel to the force-applying rod 130. Since the gripping rod connecting rod 160 is perpendicular to the force-applying rod 130, in these embodiments, both the first gripping rod 140 and the second gripping rod 150 are perpendicular to the gripping rod connecting rod 160.

[0089] In some embodiments, the grip connection 1133 is parallel to the grip rod connection 160.

[0090] Users can use the immersion-type nozzle clamp 100 of this application by following the steps below:

[0091] First, the operator rotates the rotating part 121, causing the second clamping part 123 to move away from the first clamping part 112, until the gap between the first clamping part 112 and the second clamping part 123 can accommodate the immersion nozzle.

[0092] Next, the first worker holds the first grip rod 140 and the second grip rod 150 with both hands, and the second worker holds the first grip part 1131 and the second grip part 1132 with both hands, moving the immersion nozzle clamp 100 so that the immersion nozzle is located between the first clamping member 112 and the second clamping member 123.

[0093] Next, the second worker releases the first grip 1131 and the second grip 1132 with both hands, and holds the connecting rod 111 with one hand while rotating the rotating part 121 with the other hand, so that the second clamping part 123 moves toward the first clamping part 112 until the first clamping part 112 and the second clamping part 123 clamp the immersion nozzle.

[0094] Next, the second worker released the connecting rod 111 and the rotating part 121 with both hands, and then held the first gripping part 1131 and the second gripping part 1132 with both hands respectively.

[0095] Next, two workers lifted and moved the immersion nozzle clamp 100, moving the immersion nozzle on it to the designated position.

[0096] Next, the second worker releases the first grip 1131 and the second grip 1132 with both hands, and holds the connecting rod 111 with one hand while rotating the rotating part 121 with the other hand, so that the second clamping part 123 moves away from the first clamping part 112 until the first clamping part 112 and the second clamping part 123 no longer clamp the submersible nozzle and separate the submersible nozzle from the submersible nozzle clamp 100.

[0097] Next, the second worker releases the connecting rod 111 and the rotating part 121 with both hands, and then grasps the first gripping part 1131 and the second gripping part 1132 with both hands respectively.

[0098] Next, two workers lifted and moved the submersible nozzle clamp 100 to its storage location, thus completing the transfer of the submersible nozzle.
