Technical Field

[0001] This utility model relates to the field of continuous casting machine technology, specifically a special protective device for the mushroom head of a fan-shaped banana beam. Background Technology

[0002] As a key component of the continuous casting machine, the mushroom head serves as a connecting and supporting element, and its performance stability directly affects the production efficiency and billet quality of the continuous casting machine. However, in actual production and maintenance, the fan-shaped mushroom head faces many serious problems, severely threatening the safe operation of the equipment and the continuity of production.

[0003] During the maintenance and replacement of the sector section, the mushroom head of the sector section is in a relatively open state. The complex working environment on site makes it easy for debris such as steel slag and iron filings to enter the internal structure and related connection parts of the mushroom head. Steel slag has high hardness and irregular shape. Once it falls into the mushroom head, it will cause problems such as accelerated wear and reduced fit accuracy during subsequent operation. This will affect the supporting and guiding function of the sector section for the cast billet, resulting in quality defects on the surface of the cast billet. Utility Model Content

[0004] In view of this, the present invention provides a special protective device for the mushroom head of a fan-shaped banana beam, which aims to solve the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides a special protective device for the mushroom-shaped head of a banana-shaped section beam, comprising: The box body contains multiple clamping components for clamping the mushroom head placed inside the box body, and the top of the box body is the feed inlet; The cover is openable and closable and located on the feed inlet at the top of the box. The cover has multiple through holes, which correspond to and fit with multiple mushroom heads. The upper cover is located above the cover body. Multiple cylindrical covers are fixed between the upper cover and the cover body. Each cylindrical cover corresponds to a multiple through hole. The lower end of each cylindrical cover is connected to the corresponding through hole.

[0006] A further improvement of this utility model is that the clamping assembly includes multiple grippers, each gripper consisting of a first clamping plate and a second clamping plate, wherein the first clamping plate and the second clamping plate clamp or detach from the mushroom head under the drive of the driving assembly.

[0007] A further improvement of this utility model is that the driving assembly includes a first moving rod and a second moving rod, which are respectively disposed on both sides of the gripper. The first moving rod is connected to the first end of the first clamping plate and is slidably connected to and passes through the first end of the second clamping plate. The second moving rod is connected to the second end of the second clamping plate and is slidably connected to and passes through the second end of the first clamping plate. When the first moving rod moves horizontally under the drive of the driving member, the second moving rod is driven to move in the opposite direction through the transmission assembly.

[0008] A further improvement of this utility model is that the driving component is a first screw, the first end of the first screw is connected to the end shaft of the first moving rod, and the second end of the first screw is threadedly connected to the side wall of the housing and a handwheel is fixed therethrough.

[0009] A further improvement of this utility model is that the transmission assembly includes a connecting rod, which is horizontally and rotatably disposed between the first moving rod and the second moving rod, and the two through slots at both ends of the connecting rod are slidably connected to the two guide shafts on the first moving rod and the second moving rod, respectively.

Detailed Implementation

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, in the following description, specific details such as particular system structures and technologies are set forth for illustrative purposes rather than for limiting purposes, in order to provide a thorough understanding of the embodiments of the present invention. However, those skilled in the art should understand that the present invention can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details hindering the description of the present invention.

[0017] This utility model provides a special protective device for the mushroom head of a fan-shaped banana-shaped beam, as detailed in the attached instruction manual. Figure 1 To be continued Figure 3 It can be seen that a special protective device for the mushroom head of a fan-shaped banana beam mainly includes the following parts or components: box body 10, cover body 11, and top cover 12.

[0018] In this utility model, the box body 10 is provided with multiple clamping components 20, which are used to clamp the mushroom heads placed in the box body 10. The top of the box body 10 is a feeding port, and the cover 11 is openable and closable on the feeding port at the top of the box body 10. The cover 11 is provided with multiple through holes, which correspond one-to-one with and are adapted to the multiple mushroom heads. The upper cover 12 is provided above the cover 11, and multiple cylindrical covers 13 are fixed between the upper cover 12 and the cover 11. The multiple cylindrical covers 13 correspond one-to-one with the multiple through holes, and the lower end of the cylindrical cover 13 is connected to the corresponding through hole.

[0019] Open the cover 11 (at this time, the upper cover 12 opens along with the cover 11). The multiple clamping components 20 inside the box 10 are initially released, that is, there is a sufficient gap between the first clamping plate 21 and the second clamping plate 22 of the clamping claw to facilitate the insertion of the mushroom head. Put the multiple mushroom heads to be protected one by one into the box 10 through the feed port at the top of the box 10, so that each mushroom head can enter the clamping area and be clamped by the clamping components 20. Cover the cover 11 on the feed port at the top of the box 10, so that the multiple through holes on the cover 11 correspond one by one with the multiple mushroom heads inside the box 10. The protruding structure at the top of the mushroom head passes through the corresponding through hole, achieving initial positioning and sealing. After the protruding structure at the top of the mushroom head passes through the through hole, it enters the corresponding cylindrical cover 13. The cylindrical cover 13 further wraps the protruding part of the mushroom head from above, preventing steel slag, iron filings and other debris from falling into the connection part or internal structure of the mushroom head from the top.

[0020] The housing 10 can completely house the mushroom head, preventing steel slag and iron filings from the external environment from falling directly onto the surface of the mushroom head. The through hole of the cover 11 is precisely matched with the mushroom head, and together with the cylindrical cover 13, it forms a vertical protective channel, which can not only adapt to the protruding structure of the mushroom head, but also prevent horizontally falling debris from entering the connection part. The closed design of the cover 11 and the top cover 12 further isolates the top contaminants, reducing the risk of debris entering the inside of the mushroom head and the connection part from the source, ensuring the fitting accuracy and wear stability during subsequent operation, and reducing the occurrence rate of casting quality defects.

[0021] The clamping assembly 20 can prevent the mushroom head from shaking or colliding inside the housing 10, causing secondary damage, and can also ensure the precise alignment of the mushroom head with the through hole of the cover 11 and the cylindrical cover 13, ensuring that the protective structure effectively covers the key parts and improves the reliability of protection.

[0022] As one embodiment, in conjunction with the appendix to the specification Figure 2It is known that the clamping assembly 20 includes multiple grippers, each gripper consisting of a first clamping plate 21 and a second clamping plate 22. The first clamping plate 21 and the second clamping plate 22 clamp or disengage from the mushroom head under the drive of the driving assembly. The driving assembly includes a first moving rod 23 and a second moving rod 24, respectively disposed on both sides of the gripper. The first moving rod 23 is connected to the first end of the first clamping plate 21 and is slidably connected to and passes through the first end of the second clamping plate 22. The second moving rod 24 is connected to the second end of the second clamping plate 22 and is slidably connected to and passes through the second end of the first clamping plate 21. When the first moving rod 23 moves horizontally under the drive of the driving component, the second moving rod 24 is driven to move in the opposite direction through the transmission assembly. The driving component is a first screw 25. The first end of the first screw 25 is connected to the end shaft of the first moving rod 23, and the second end of the first screw 25 is threadedly connected to the side wall of the housing 10 and passes through, after which a handwheel 251 is fixed. The transmission assembly includes a connecting rod 26, which is horizontally and rotatably disposed between the first moving rod 23 and the second moving rod 24. The two through slots 261 at both ends of the connecting rod 26 are slidably connected to the two guide shafts 27 on the first moving rod 23 and the second moving rod 24, respectively.

[0023] Insert the mushroom-shaped head into the housing 10 through the feed inlet, positioning it between the first clamping plate 21 and the second clamping plate 22. Turn the handwheel 251, causing the first screw 25 to rotate. Since the first screw 25 is threadedly connected to the side wall of the housing 10, the rotating screw will push the first moving rod 23 to move horizontally. As the first moving rod 23 moves, its end guide shaft 27 slides within the through groove 261 at one end of the connecting rod 26, causing the connecting rod 26 to rotate around its central pivot point. The through groove 261 at the other end of the connecting rod 26 then pushes the guide shaft 27 on the second moving rod 24, causing the second moving rod 24 to move horizontally relative to the first moving rod 24. As the first moving rod 23 and the second moving rod 24 move in opposite directions, the first end of the first clamping plate 21 connected to the first moving rod 23 and the second end of the second clamping plate 22 connected to the second moving rod 24 are synchronously driven, and the first clamping plate 21 and the second clamping plate 22 gradually move closer to each other. At the same time, the first moving rod 23 passes through the first end of the second clamping plate 22 and the second moving rod 24 passes through the second end of the first clamping plate 21. The two maintain stable guidance at the sliding penetration point. Finally, the first clamping plate 21 and the second clamping plate 22 are tightly fitted against both sides of the mushroom head, completing the clamping action, and the rotation of the handwheel 251 stops. Rotating the handwheel 251 in the opposite direction causes the first screw 25 to pull the first moving rod 23 to move in the opposite direction. Through the transmission of the connecting rod 26, the second moving rod 24 moves in the opposite direction to the first moving rod 23, and the first clamping plate 21 and the second clamping plate 22 separate, allowing the mushroom head to be removed from the box 10.

[0024] As one embodiment, in conjunction with the appendix to the specification Figure 3It can be seen that the upper end of the side wall of the box 10 is provided with a groove 101, and the lower end of the cover 11 is provided with a locking block 111 corresponding to the groove 101. The locking block 111 is adapted to the groove 101.

[0025] A handle is installed on the top cover 12. Pulling the handle upward will cause the top cover 12, the cylindrical cover 13, and the cover body 11 to move upward together, so that the locking block 111 at the lower end of the cover body 11 separates from the groove 101 at the upper end of the side wall of the box body 10, thus opening the cover body 11 and exposing the feed port at the top of the box body 10. When it is necessary to close the cover, the cover body 11 can be closed again on the box body 10. The locking block 111 and the groove 101 are used to fix the cover body 10, keeping the inside of the box body 10 clean and preventing foreign objects from entering the box body 10.

[0026] As one embodiment, in conjunction with the appendix to the specification Figure 1 It can be seen that the bottom of the box 10 is equipped with multiple brakeable casters 14.

[0027] Operators can easily move the box 10 within the workshop without the need for large lifting equipment or multiple people working together. Whether moving it from the storage area to the maintenance work point or switching between different work areas, the position can be flexibly adjusted, saving labor costs. It is especially suitable for complex environments with limited space and dense equipment at the maintenance site of continuous casting machines.
