Description

Technical Field

[0001] This utility model relates to the field of metal heat treatment, specifically to a high-strength steel grating quenching device. Background Technology

[0002] Steel grating is a steel product made by arranging flat steel bars at certain intervals and crossbars, and welding them together to form a grid with square openings. It is mainly used for drainage ditch covers, steel structure platform panels, and steel stair treads. The crossbars are generally made of twisted square steel. Quenching steel plates can improve their rigidity, hardness, wear resistance, fatigue strength, and toughness.

[0003] A steel grating spray quenching device is mentioned in an existing Chinese patent (authorization announcement number: CN215560470U). It includes a worktable with a bidirectional threaded rod rotatably connected to it. A drive component is provided on the worktable to rotate the bidirectional threaded rod. A guide rod is provided on the worktable. A spray plate is threadedly connected to both ends of the bidirectional threaded rod, with opposite thread directions. The guide rod passes through both spray plates. Spray pipes are provided on the spray plates, and the spray pipes on the two spray plates are arranged opposite each other. One end of each spray pipe is closed, and the other end is connected to a water supply component. Multiple spray holes are opened on the spray pipes, facing the steel grating to be quenched. This application has the effect of improving work efficiency.

[0004] Existing equipment requires placing the steel grating between spray pipes during quenching. Then, quenching liquid is sprayed onto the middle steel grating through the spray pipes on both sides to quench it. However, existing equipment can only make minor adjustments to the distance between the steel grating and the spray pipes on both sides during the quenching process. This only slightly changes the horizontal landing position of the quenching liquid on the steel plate by gravity. This makes it difficult to ensure that corners of the steel grating that are not easily sprayed with quenching liquid are sprayed with quenching liquid by changing the distance of the spray pipes. It also makes it difficult to collect the sprayed quenching liquid, resulting in waste and hindering recycling. Utility Model Content

[0005] The purpose of this application is to solve the problems that existing steel gratings are difficult to spray with quenching liquid in the corners, making it difficult to obtain quenching liquid by changing the distance of the spray pipe, and also making it difficult to collect the sprayed quenching liquid, resulting in waste. This application provides a high-strength steel grating quenching device.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A high-strength steel grating quenching device includes a base, side plates fixedly connected to both sides of the base, a movable frame mounted on the upper end of the side plates, a spray pipe fixedly connected inside the movable frame, a plurality of spray nozzles fixedly connected to the outer surface of the spray pipe, a collection groove opened at the upper end of the base, a rotating platform rotatably connected inside the collection groove, a clamping frame mounted on the rotating platform, a drive motor fixedly connected inside the base, the output end of the drive motor fixedly connected to the rotating platform, and an adjustment structure provided inside the base.

[0008] By adopting the above technical solution, when the device needs to quench the steel grating, the steel grating is first placed on the rotating table and limited by the clamping frame. Then, the quenching liquid is transported through the spray pipe on the moving frame and sprayed onto the steel grating through the spray nozzles on the surface of the spray pipe. After the initial quenching, the rotating table is rotated, causing the clamping frame to rotate, thereby causing the steel grating to rotate 30 degrees around the rotating table as an axis. While the steel grating is rotating, the moving frame is moved to continue spraying the quenching liquid onto the steel grating through the spray pipe and nozzle. This allows the quenching liquid to be sprayed onto the surface of the steel grating from multiple angles by changing the angle of the steel grating during the quenching process. This reduces the quenching dead angles of the steel grating during spraying, resulting in a better quenching effect. At the same time, the used quenching liquid is collected through the collection tank, which reduces the waste of quenching liquid and saves a lot of quenching liquid consumption.

[0009] Furthermore, a gear is fixedly connected to the output end of the drive motor, and a toothed plate is fixedly connected to one side of the movable frame. The toothed plate meshes with the gear, and sliding grooves are provided inside both the movable frame and the base. The size of the sliding grooves is adapted to the toothed plate.

[0010] By adopting the above technical solution, the drive motor is started to drive the rotating table to rotate, so that the rotating table drives the steel grating to rotate 30 degrees around the rotating table as the axis. At the same time, the rotation of the drive motor also drives the gear to rotate. When the gear rotates, it drives the two toothed plates to move, so that the toothed plates move in opposite directions. This drives the moving frame to move along the moving groove on the side plate through the moving wheels. While rotating the steel grating, the angle of the moving frame is also adjusted. This allows the angle of the steel grating to be changed during the quenching process.

[0011] Furthermore, a movable groove is provided at the upper end of the side plate, and a movable wheel is fixedly connected to the lower end of the movable frame, with the movable wheel located inside the movable groove.

[0012] Furthermore, a connecting pipe is fixedly connected inside the collection tank, and a water tank is fixedly connected to the end of the connecting pipe.

[0013] By adopting the above technical solution, the used quenching liquid is collected in the collection tank and then stored back in the water tank through the connecting pipe, which can reduce the waste of quenching liquid and save a lot of quenching liquid consumption.

[0014] Furthermore, a corrugated pipe is fixedly connected to the end of the spray pipe, and a water pump is fixedly connected to the end of the corrugated pipe. The water pump is fixedly connected to the water tank.

[0015] By adopting the above technical solution, the water pump is started to extract the quenching liquid in the water tank through the corrugated pipe, so that the quenching liquid enters the spray pipe. The corrugated pipe is also stretched during the movement of the moving frame, so that the quenching work can continue after the moving frame moves.

[0016] Furthermore, a bidirectional screw is rotatably connected inside the rotating platform, and a rotating plate is rotatably connected outside the rotating platform. The rotating plate is fixedly connected to the bidirectional screw, and clamping frames are threaded to both ends of the bidirectional screw.

[0017] By adopting the above technical solution, the rotating plate drives the bidirectional screw to rotate, which causes the two clamping frames to move towards each other or in opposite directions, in order to adapt to steel gratings of different sizes.

[0018] Furthermore, a connecting plate is slidably connected inside the clamping frame. The connecting plate is a telescopic plate. A sliding column is slidably connected to one end of the clamping frame. A clamping plate is fixedly connected to the end of the sliding column. An inclined groove is opened and closed at the upper end of the clamping plate.

[0019] By adopting the above technical solution, the diameter of the connecting plate located between the two clamping frames is the diameter of the steel grating that the clamping frame can accommodate. When installing the steel grating, the steel grating is first lifted up, and then the steel grating is lifted and placed towards the connecting plate between the two clamping frames. When the steel grating moves towards the connecting plate, it will be limited by the inclined groove at the upper end of the clamping plate, allowing it to fall vertically onto the connecting plate.

[0020] Furthermore, a spring is sleeved on the outer side of the sliding column, and the two ends of the spring are fixedly connected to the clamping plate and the clamping frame, respectively.

[0021] By adopting the above technical solution, the spring continuously resets and pushes the clamping plates on both sides to clamp the steel grating, allowing the device to quench steel gratings of different sizes.

[0022] In summary, this application includes at least one of the following beneficial effects;

[0023] In this application, when using the device to quench steel grating, the water pump is started to extract the quenching liquid from the water tank through the corrugated pipe, allowing the quenching liquid to be evenly sprayed onto the steel grating on the rotating platform from both sides through the nozzles. Then, the drive motor is started to drive the rotating platform to rotate, causing the steel grating to rotate 30 degrees around the rotating platform as an axis. At the same time, the toothed plate moves in the opposite direction, which drives the moving frame to move along the moving groove on the side plate through the moving wheels. While rotating the steel grating, the angle of the moving frame is also adjusted. This allows the quenching liquid to be sprayed onto the surface of the steel grating from multiple angles by changing the angle of the steel grating during the quenching process. This reduces the quenching dead angles of the steel grating during spraying, resulting in a better quenching effect. At the same time, the used quenching liquid is collected through the collection tank and then stored back into the water tank through the connecting pipe, which reduces the waste of quenching liquid and saves a lot of quenching liquid.

[0024] In this application, before quenching the steel grating, the spacing of the clamping frame can be adjusted according to the size of the steel grating to be quenched. When installing the steel grating, it is first hoisted up. When the steel grating moves towards the connecting plate, it is limited by the inclined groove at the upper end of the clamping plate, allowing it to fall vertically onto the connecting plate. At the same time, it pushes the clamping plates on both sides of the steel grating, allowing the clamping plates to move along the sliding column towards the clamping frame, thereby causing the spring to be compressed and expand until the steel grating falls onto the connecting plate. At this time, the spring continues to reset and push the clamping plates on both sides to clamp the steel grating. This allows the device to quench steel gratings of different sizes. It also allows the steel grating to be moved by a crane during installation and disassembly, without the need for additional fixing and disassembly work, making the movement of the steel grating during the quenching process more convenient.

Detailed Implementation

[0032] The following will be based on the embodiments of this utility model. Figures 1-5 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] Reference Figure 1 and Figure 2 This utility model provides a technical solution: a high-strength steel grating quenching device, including a base 1, side plates 3 fixedly connected to both sides of the base 1, a movable frame 2 installed on the upper end of the side plates 3, a spray pipe 8 fixedly connected inside the movable frame 2, a plurality of spray nozzles fixedly connected to the outer surface of the spray pipe 8, a collection groove 9 opened at the upper end of the base 1, a rotating table 10 rotatably connected inside the collection groove 9, a clamping frame 18 installed on the rotating table 10, a drive motor 12 fixedly connected inside the base 1, the output end of the drive motor 12 fixedly connected to the rotating table 10, and an adjustment structure provided inside the base 1.

[0034] When the device is needed to quench the steel grating, the steel grating is first placed on the rotating table 10 and the clamping frame 18 is used to limit the steel grating. Then, the quenching liquid is transported through the spray pipe 8 on the moving frame 2 and sprayed onto the steel grating through the spray nozzles on the surface of the spray pipe 8. After the initial quenching, the rotating table 10 is rotated so that the clamping frame 18 rotates along with it, thereby causing the steel grating to rotate 30 degrees around the rotating table 10 as an axis. While the steel grating is rotating, the moving frame 2 is moved so that it continues to spray the quenching liquid onto the steel grating through the spray pipe 8 and the nozzle. This allows the quenching liquid to be sprayed onto the surface of the steel grating from multiple angles by changing the angle of the steel grating during the quenching process. This reduces the quenching dead angles of the steel grating during spraying, resulting in a better quenching effect. At the same time, the used quenching liquid is collected through the collection tank 9, which reduces the waste of quenching liquid and saves a lot of quenching liquid consumption.

[0035] Reference Figure 1 and Figure 2 , Figure 3A gear 13 is fixedly connected to the output end of the drive motor 12. A toothed plate 14 is fixedly connected to one side of the movable frame 2, and the toothed plate 14 meshes with the gear 13. Both the movable frame 2 and the base 1 have sliding grooves inside, and the size of the sliding grooves is adapted to the toothed plate 14. A moving groove 5 is opened at the upper end of the side plate 3, and a moving wheel 4 is fixedly connected to the lower end of the movable frame 2. The moving wheel 4 is located inside the moving groove 5. A connecting pipe 15 is fixedly connected inside the collection tank 9, and a water tank 6 is fixedly connected to the end of the connecting pipe 15. A corrugated pipe 7 is fixedly connected to the end of the spray pipe 8, and a water pump 11 is fixedly connected to the end of the corrugated pipe 7. The water pump 11 is fixedly connected to the water tank 6.

[0036] When using this device to quench the steel grating, the water pump 11 is started to extract the quenching liquid from the water tank 6 through the corrugated pipe 7, allowing the quenching liquid to enter the spray pipe 8. By continuously injecting the quenching liquid, the water pressure inside the spray pipe 8 is increased, causing the quenching liquid to be evenly sprayed from both sides onto the steel grating on the rotating platform 10 through the nozzles. Then, the drive motor 12 is started to drive the rotating platform 10 to rotate, causing the steel grating to rotate 30 degrees around the rotating platform 10 as an axis. At the same time, the rotation of the drive motor 12 also drives the gear 13 to rotate. When the gear 13 rotates, it simultaneously drives the two toothed plates 14 to move, causing the toothed plates 14 to move. Moving in the opposite direction causes the moving frame 2 to move along the moving groove 5 on the side plate 3 via the moving wheels 4. While rotating the steel grating, the angle of the moving frame 2 is also adjusted. This allows the quenching liquid to be sprayed onto the surface of the steel grating at multiple angles during the quenching process by changing the angle of the steel grating. This reduces the quenching dead angles of the steel grating during spraying, resulting in a better quenching effect. At the same time, the used quenching liquid is collected through the collection tank 9 and then stored back into the water tank 6 through the connecting pipe 15, which reduces the waste of quenching liquid and saves a lot of quenching liquid consumption.

[0037] Reference Figure 2 and Figure 4 , Figure 5 The rotating platform 10 has a bidirectional screw 17 rotatably connected inside, and a rotating plate 16 rotatably connected to the outside of the rotating platform 10. The rotating plate 16 is fixedly connected to the bidirectional screw 17, and both ends of the bidirectional screw 17 are threadedly connected to clamping frames 18. A connecting plate 22, which is a telescopic plate, is slidably connected inside the clamping frame 18. A sliding post 19 is slidably connected to one end of the clamping frame 18, and a clamping plate 21 is fixedly connected to the end of the sliding post 19. The upper end of the clamping plate 21 has an inclined groove. A spring 20 is sleeved on the outside of the sliding post 19, and both ends of the spring 20 are fixedly connected to the clamping plate 21 and the clamping frame 18, respectively.

[0038] Before quenching the steel grating, the spacing of the clamping frames 18 can be adjusted according to the size of the steel grating to be quenched. First, rotate the rotating plate 16 to drive the bidirectional screw 17 to rotate, which causes the two clamping frames 18 to move towards each other or in opposite directions. At this time, the diameter of the connecting plate 22 located between the two clamping frames 18 is the diameter of the steel grating that the clamping frame 18 can accommodate. When installing the steel grating, first lift the steel grating, and then lift the steel grating onto the connecting plate 22 between the two clamping frames 18. When the steel grating moves toward the connecting plate 22, it will be limited by the inclined groove at the upper end of the clamping plate 21. The steel grating is allowed to fall vertically onto the connecting plate 22, which in turn pushes the clamping plates 21 on both sides of the steel grating. The clamping plates 21 move along the sliding column 19 towards the clamping frame 18, which in turn compresses and extends the spring 20 until the steel grating falls onto the connecting plate 22. At this time, the spring 20 continues to reset and push the clamping plates 21 on both sides to clamp the steel grating. This allows the device to quench steel gratings of different sizes. It also allows the steel gratings to be moved by a crane during installation and disassembly without the need for additional fixing and disassembly work, making the movement of the steel gratings during the quenching process more convenient.

[0039] Working principle: When using this device to quench the steel grating, the water pump 11 is started to extract the quenching liquid from the water tank 6 through the corrugated pipe 7, allowing the quenching liquid to enter the spray pipe 8. The continuous injection of quenching liquid pressurizes the water inside the spray pipe 8, causing the quenching liquid to be evenly sprayed from both sides onto the steel grating on the rotating platform 10 through the nozzles. Then, the drive motor 12 is started to rotate the rotating platform 10, causing the steel grating to rotate 30 degrees around the rotating platform 10 as its axis. Simultaneously, the rotation of the drive motor 12 also drives the gear 13 to rotate. When the gear 13 rotates, it simultaneously moves two toothed plates 14, causing the teeth to... Plate 14 moves in the opposite direction, which drives the moving frame 2 to move along the moving groove 5 on the side plate 3 via the moving wheel 4. While rotating the steel grating, the angle of the moving frame 2 is also adjusted. This allows the quenching liquid to be sprayed onto the surface of the steel grating at multiple angles by changing the angle of the steel grating during the quenching process. This reduces the quenching dead angles of the steel grating during spraying, resulting in a better quenching effect. At the same time, the used quenching liquid is collected by the collection tank 9 and then stored back into the water tank 6 through the connecting pipe 15, which reduces the waste of quenching liquid and saves a lot of quenching liquid.

[0040] Before quenching the steel grating, the spacing of the clamping frames 18 can be adjusted according to the size of the steel grating to be quenched. First, rotate the rotating plate 16 to drive the bidirectional screw 17 to rotate, which causes the two clamping frames 18 to move towards each other or in opposite directions. At this time, the diameter of the connecting plate 22 located between the two clamping frames 18 is the diameter of the steel grating that the clamping frame 18 can accommodate. When installing the steel grating, first lift the steel grating, and then lift the steel grating onto the connecting plate 22 between the two clamping frames 18. When the steel grating moves toward the connecting plate 22, it will be limited by the inclined groove at the upper end of the clamping plate 21. The steel grating is allowed to fall vertically onto the connecting plate 22, which in turn pushes the clamping plates 21 on both sides of the steel grating. The clamping plates 21 move along the sliding column 19 towards the clamping frame 18, which in turn compresses and extends the spring 20 until the steel grating falls onto the connecting plate 22. At this time, the spring 20 continues to reset and push the clamping plates 21 on both sides to clamp the steel grating. This allows the device to quench steel gratings of different sizes. It also allows the steel gratings to be moved by a crane during installation and disassembly without the need for additional fixing and disassembly work, making the movement of the steel gratings during the quenching process more convenient.
