Description

Technical Field

[0001] This utility model relates to the field of steel structure processing, specifically a cooling device for rapid cooling of steel structure heat treatment. Background Technology

[0002] Heat treatment of steel structures is a process of heating, holding and cooling steel or steel structural components to change their internal structure and obtain the desired properties. Cooling is the key link in the entire heat treatment process. The core is to fix the microstructure formed during the heating and holding stages by controlling the cooling rate and method, and finally achieve the expected material properties.

[0003] In the prior art, some cooling devices consist of a cooling tank and a circulating cooling pipe. The operation method is to add an appropriate amount of coolant into the cooling tank and then circulate the cooling tank through the circulating cooling pipe. When in use, the heated steel structure can be directly immersed in the cooling tank so that all surfaces of the steel structure can come into contact with the coolant, thereby achieving rapid and comprehensive cooling.

[0004] However, this type of rapid cooling device for steel structure heat treatment has certain drawbacks. To ensure that the steel structure can smoothly enter and exit the middle of the cooling box, the top of the cooling box is designed to be open. During use, the steel structure is placed into the middle of the cooling box using a hook, and then lifted out directly after cooling is completed. However, during use, the open cooling box is prone to causing the coolant to boil and splash due to the extremely high temperature of the steel structure. The splashed coolant may cause injury to workers, making it impractical. Therefore, a rapid cooling device for steel structure heat treatment is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, some rapid-cooling steel structure heat treatment cooling devices may cause boiling coolant to splash and injure workers during use. This invention proposes a rapid-cooling steel structure heat treatment cooling device.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a cooling device for heat treatment of steel structure that can be cooled quickly, including a cooling box, a sealing cover plate slidably connected to the top of the cooling box, a through groove opened on the top of the cooling box, a cylindrical tube fixedly connected to the middle of the through groove, a cylindrical slide tube slidably connected to the middle of the cylindrical tube, a spring fixedly connected to the middle of the cylindrical slide tube, the other end of the spring fixedly connected to the middle of the cylindrical tube, a rectangular frame slidably connected to the middle of the cooling box, a pull rope fixedly connected to the top of the rectangular frame, a roller rotatably connected to the side wall of the middle of the cooling box, the outer wall of the pull rope sliding in the middle of the roller, a rotating rod fixedly connected to the other end of the pull rope, a fixing block fixedly connected to the bottom of the sealing cover plate, the end of the rotating rod rotatably connected to the middle of the fixing block, an arc groove opened on the side wall of the sealing cover plate, and a filter shell contacting the middle of the rectangular frame.

[0007] Preferably, the rectangular frame has a rectangular groove at its top, a rectangular block is slidably connected to the middle of the rectangular groove, a limiting plate is slidably connected through the side wall of the rectangular frame, a limiting groove is opened on the side wall of the filter shell, the limiting plate is inserted into the middle of the limiting groove, a rectangular plate is fixedly connected to the end of the limiting plate, a connecting plate is rotatably connected to the top side wall of the rectangular plate, a hinge block is rotatably connected to the other end of the connecting plate, a through groove is opened at the top of the connecting plate, the outer wall of the end of the pull rope slides in the middle of the through groove, and the top of the rectangular block is fixedly connected to the bottom of the hinge block.

[0008] Preferably, a sliding plate is fixed to the side wall of the rectangular frame, a sliding groove is provided in the middle of the cooling box, a second rectangular groove is provided on the side wall of the sliding plate, and a roller is rotatably connected to the middle of the second rectangular groove, and the roller rolls in the middle of the sliding groove.

[0009] Preferably, multiple sets of cylindrical slide cylinders, cylindrical tubes, and springs are provided, and multiple sets of cylindrical slide cylinders, cylindrical tubes, and springs are provided at the bottom of the rectangular frame.

[0010] Preferably, handles are fixed to the top sides of both ends of the filter housing.

[0011] Preferably, the sidewall of the limiting plate is configured as an inclined surface.

[0012] Preferably, a second spring is fixedly connected to the bottom of the rectangular block, and the bottom of the second spring is fixedly connected to the middle of the rectangular groove.

[0013] Preferably, the sealing cover is provided in multiple sets, and the multiple sets of sealing cover are symmetrically arranged with the center line of the cooling box as the axis of symmetry, and the side wall of the sealing cover is provided with an arc-shaped groove.

[0014] Compared with the prior art, this utility model, by setting up a cylindrical slide, a cylindrical tube, a spring, a rectangular frame, a slide groove, a fixing block, a pull rope, a rotating rod, and a roller, ensures that the sealing cover will automatically close when the steel is placed in the middle of the cooling box, reducing the risk of workers being injured by the boiling and splashing of coolant and improving practicality. In addition, the filter shell can collect impurities that fall on the steel, further improving practicality.

[0015] This invention places steel in a filter housing. The steel, by its own weight, causes the filter housing and rectangular frame to descend into the coolant. The rectangular frame, through an arc groove, moves a rotating rod, a fixing block, and a sealing cover, causing the sealing cover to close. This achieves the effect of shielding the top of the cooling tank when the steel is placed in the middle, thus solving the problem of boiling coolant splashing and causing injury to workers.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] The following is in conjunction with the appendix Figure 1 - Figure 7 This application will be described in further detail. This application discloses a rapid cooling device for heat treatment of steel structures. (Refer to...) Figure 1 - Figure 2 and Figure 5 - Figure 6A rapid cooling device for heat treatment of steel structures includes a cooling box 1. A sealing cover 2 is slidably connected to the top of the cooling box 1. A through groove 6 is formed on the top of the cooling box 1. A cylindrical tube 5 is fixedly connected to the middle of the through groove 6. A cylindrical slide tube 4 is slidably connected to the middle of the cylindrical tube 5. A spring 7 is fixedly connected to the middle of the cylindrical slide tube 4. The other end of the spring 7 is fixedly connected to the middle of the cylindrical tube 5. A rectangular frame 8 is slidably connected to the middle of the cooling box 1. A pull rope 12 is fixedly connected to the top of the rectangular frame 8. A roller 14 is rotatably connected to the side wall of the middle part of the cooling box 1. The outer wall of the pull rope 12 slides on the middle part of the roller 14. A rotating rod 13 is fixedly connected to the other end of the pull rope 12. A fixing block 11 is fixedly connected to the bottom of the sealing cover plate 2. The end of the rotating rod 13 is rotatably connected to the middle part of the fixing block 11. The middle part of the rectangular frame 8 contacts the filter shell 3. During operation, when it is necessary to cool the steel, a crane can be used to place the steel in the middle of the filter shell 3. At this time, the steel will be driven by its own gravity. The filter shell 3 and rectangular frame 8 move downwards, allowing the steel to smoothly enter the coolant in the middle of the cooling tank 1. When the rectangular frame 8 moves, it drives the fixed block 11 to move via the pull rope 12 and rotating rod 13. The fixed block 11 then drives the sealing cover 2 to move. In this way, multiple sets of sealing covers 2 will close when the steel is placed in the middle of the cooling tank 1. In addition, when the sealing cover 2 moves, it will drive the cylindrical slide 4 to move in the middle of the cylindrical cylinder 5. At the same time, the cylindrical slide 4 will squeeze the spring 7. After the steel has cooled and moved out of the middle of the cooling tank 1, the spring 7 will push the cylindrical slide 4 to move in the opposite direction to reset through its own elasticity. The sealing cover 2, fixed block 11, pull rope 12, rotating rod 13 and rectangular frame 8 will also reset accordingly, improving practicality. Through the above operation, it can be ensured that when the steel is cooled in the middle of the cooling tank 1, the boiling and splashing coolant will be blocked by the sealing cover 2, reducing the risk of splashing out from the middle of the cooling tank 1 and causing injury to workers, thus improving practicality.

[0021] Reference Figure 2 , Figure 4 , Figure 6 and Figure 7The rectangular frame 8 has a rectangular groove 83 at its top, and a rectangular block 95 is slidably connected to the middle of the rectangular groove 83. A limiting plate 92 is slidably connected through the side wall of the rectangular frame 8. The filter shell 3 has a limiting groove 32 on its side wall, and the limiting plate 92 is inserted into the middle of the limiting groove 32. A rectangular plate 93 is fixed to the end of the limiting plate 92. A connecting plate 91 is rotatably connected to the top side wall of the rectangular plate 93. A hinge block 9 is rotatably connected to the other end of the connecting plate 91. A through groove 96 is formed at the top of the connecting plate 91. The outer wall of the end of the pull rope 12 slides in the middle of the through groove 96. The top of the rectangular block 95 is fixed to the bottom of the hinge block 9. During operation, the filter shell 3 can collect impurities falling from the steel. After a period of use, the filter shell 3 needs to be cleaned. When performing maintenance and processing impurities in the middle, the filter shell 3 can be disassembled for operation. The specific method is as follows: directly push the hinge block 9, the hinge block 9 will rotate with one end of the connecting plate 91, and the angle of the connecting plate 91 will change. The other end of the connecting plate 91 will rotate with the rectangular plate 93, and at the same time drive the rectangular plate 93 and the limiting plate 92 to move, so that the limiting plate 92 is disengaged from the middle of the limiting groove 32. In this way, the filter shell 3 can be taken out from the middle of the rectangular frame 8, which is convenient for maintenance and processing of impurities collected in the middle, improving practicality. When installing, simply place the filter shell 3 in the middle of the rectangular frame 8. The subsequent structural fit is the same as above, until the limiting plate 92 is inserted into the middle of the limiting groove 32, which improves practicality. Reference Figure 2 - Figure 4 The rectangular frame 8 has a sliding plate 81 fixed to its side wall. The cooling box 1 has a sliding groove 10 in the middle. The sliding plate 81 has a rectangular groove 84 in its side wall. A roller 82 is rotatably connected to the middle of the rectangular groove 84. The roller 82 rolls in the middle of the sliding groove 10. When the rectangular frame 8 moves in the middle of the cooling box 1, it will drive the sliding plate 81 to slide in the middle of the sliding groove 10. At the same time, the roller 82 will also roll in the middle of the sliding groove 10, ensuring the smooth movement of the rectangular frame 8 in the middle of the cooling box 1. Reference Figure 2 The cylindrical slide cylinder 4, cylindrical cylinder 5, and spring 7 are provided in multiple sets, and the multiple sets of cylindrical slide cylinder 4, cylindrical cylinder 5, and spring 7 are located at the bottom of the rectangular frame 8. During operation, the multiple sets of cylindrical slide cylinder 4, cylindrical cylinder 5, and spring 7 can support the bottom of the rectangular frame 8, ensuring that the rectangular frame 8 can move quickly and stably from the bottom side of the middle of the cooling box 1 to the top side, thus improving practicality. Reference Figure 2 and Figure 4 The filter housing 3 is fixedly connected to the top side of both ends with handles 31. During operation, the multiple sets of handles 31 make it easy to pick up the filter housing 3, thus improving its practicality. Reference Figure 4 The side wall of the limiting plate 92 is set as an inclined surface. During operation, the inclined surface ensures that when the filter shell 3 is installed, it will push the limiting plate 92 to move along the inclined surface. The limiting plate 92 will drive the rectangular plate 93, the connecting plate 91 and the hinge block 9 to move synchronously until the limiting plate 92 coincides with the limiting groove 32. Then the limiting plate 92 can be reset and inserted into the middle of the limiting groove 32 to limit the filter shell 3, which improves the speed of installation. Reference Figure 7 The bottom of the rectangular block 95 is fixedly connected to a second spring 94, which is fixedly connected to the middle of the rectangular groove 83. During operation, the second spring 94 ensures that when the filter shell 3 is installed, the squeezed limiting plate 92 can quickly reset when it coincides with the limiting groove 32, thus ensuring the stability of the limiting plate 92. Reference Figure 1 - Figure 2 The sealing cover 2 is provided in multiple sets, and the multiple sets of sealing cover 2 are symmetrically arranged with the center line of the cooling box 1 as the axis of symmetry. The side wall of the sealing cover 2 is provided with an arc-shaped groove 21. During operation, the multiple sets of sealing cover 2 ensure the effectiveness of blocking the top of the cooling box 1, and the arc-shaped groove 21 ensures that the steel cable for lifting the steel can smoothly enter the middle of the cooling box 1, thus improving practicality.

[0022] Working principle: When steel needs to be cooled, a crane can be used to place the steel in the middle of the filter shell 3. The steel will then move downwards using its own weight, causing the filter shell 3 and rectangular frame 8 to smoothly enter the coolant in the middle of the cooling tank 1. As the rectangular frame 8 moves, it moves the fixing block 11 via the pull rope 12 and rotating rod 13. The fixing block 11 then moves the sealing cover 2. Thus, multiple sealing covers 2 close when the steel is placed in the middle of the cooling tank 1. Additionally, the movement of the sealing covers 2 moves the cylindrical slide 4... The cylindrical tube 5 moves in the middle, while the cylindrical slide tube 4 squeezes the spring 7. After the steel has cooled and moved out of the middle of the cooling box 1, the spring 7 will push the cylindrical slide tube 4 to move in the opposite direction to reset through its own elasticity. The sealing cover 2, the fixing block 11, the pull rope 12, the rotating rod 13 and the rectangular frame 8 will also reset accordingly, which improves practicality. Through the above operation, it can be ensured that when the steel is cooled in the middle of the cooling box 1, the boiling and splashing coolant will be blocked by the sealing cover 2, reducing the splashing from the middle of the cooling box 1 and causing injury to workers, thus improving practicality.

[0023] The filter shell 3 can collect impurities that fall onto the steel. When the filter shell 3 needs maintenance and removal of impurities after a period of use, it can be disassembled. Specifically, the hinge block 9 is pushed directly, causing it to rotate with one end of the connecting plate 91, changing the angle of the connecting plate 91. The other end of the connecting plate 91 then rotates with the rectangular plate 93, simultaneously moving the rectangular plate 93 and the limiting plate 92, causing the limiting plate 92 to disengage from the center of the limiting groove 32. This allows the filter shell 3 to be removed from the rectangular frame. The middle part of the filter shell 8 is removed to facilitate maintenance and treatment of impurities collected in the middle, improving its practicality. During installation, the filter shell 3 is placed directly in the middle of the rectangular frame 8. The filter shell 3 will move along the inclined surface of the limiting plate 92. The limiting plate 92 will drive the rectangular plate 93, the connecting plate 91 and the hinge block 9 to move synchronously. The hinge block 9 will drive the hinge block 9 to move and squeeze the second spring 94 until the limiting plate 92 coincides with the limiting groove 32. The second spring 94 will reset the limiting plate 92 through its own elasticity and insert it into the middle of the limiting groove 32 to limit the filter shell 3, improving the speed of installation.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
