Description

Technical Field

[0001] This utility model relates to the field of fire hydrant casting processing technology, specifically a heat treatment device for fire hydrant castings. Background Technology

[0002] A fire hydrant is an emergency water supply device used for fire fighting. It connects to the municipal water supply pipeline, providing a high-pressure water source to quickly supply water for fire extinguishing in the event of a fire. The outer shell of the fire hydrant undergoes a quenching heat treatment process during production to increase its strength and hardness.

[0003] Existing quenching methods typically involve directly immersing the hydrant vertically into water using a robotic arm. During high-temperature heating, oxide scale or other impurities form on the surface. These substances are easily peeled off during rapid cooling and may form precipitates in the quenching liquid. Furthermore, the high-temperature fire hydrant shell vaporizes instantly upon entering the water, easily causing an air film to form on the surface of the fire hydrant shell. This can affect the full contact between the fire hydrant shell and the water, thus impacting the quenching effect.

[0004] Therefore, it is necessary to design a heat treatment device for fire hydrant castings to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a heat treatment device for fire hydrant castings to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a heat treatment device for fire hydrant castings, comprising a quenching water tank, a side plate fixedly connected to the top of the quenching water tank, and a second opening on the outer surface of the side plate; an electric cylinder fixedly inserted into the top of the quenching water tank, and a lifting sleeve fixedly connected to the top of the electric cylinder; a top plate fixedly connected to the top of the side plate, and a first opening on the outer surface of the top plate; a sliding mechanism provided inside the first opening; a sliding insert plate provided on the sliding mechanism; a first servo motor fixedly connected to the top of the sliding insert plate; a rotating column fixedly connected to the output shaft of the first servo motor; an insert square piece slidably inserted into the inside of the rotating column; a sleeve column fixedly sleeved on the outer surface of the bottom end of the insert square piece; an insert member rotatably connected to the outer surface of the sleeve column via a bearing; one end of the insert member slidably inserted into the inside of the lifting sleeve block; a robotic arm provided at the bottom end of the insert square piece; a connecting block fixedly connected to the bottom of the lifting sleeve block; and a filter screen plate fixedly connected to the bottom of the connecting block.

[0007] Preferably, the sliding mechanism includes a second servo motor, and grooves are provided on both sides of the first opening. The output shaft of the second servo motor is connected to a screw. The screw is rotatably disposed inside one groove, and a plug is fixedly connected inside the other groove. The two ends of the sliding plate are slidably inserted into the two grooves respectively, and one end of the plug is slidably inserted into one end of the sliding plate. One end of the screw is threaded into the other end of the sliding plate.

[0008] Preferably, one end of the connector is fixedly connected to a limiting piece, and one side of the limiting piece is in contact with one end of the lifting sleeve block.

[0009] Preferably, the quenching water tank has an inlet on one side and an outlet on the other side, with the inlet located on one side of the electric cylinder and above the outlet.

[0010] Preferably, the connector is Z-shaped, and one end of the connector is respectively fitted to the two sides of the inner cavity of the lifting sleeve block, and the height of the connector at one end on the lifting sleeve block side is higher than the height of the connector at one end of the sleeve post.

[0011] The technical solution provided by this utility model has the following advantages compared with the prior art:

[0012] This invention utilizes the lifting and lowering of the lifting sleeve block, the sliding insertion of the connector on the lifting sleeve block, and the rotating connection of the sleeve post on the connector to enable the robotic arm to slide in a horizontal position while simultaneously lifting and lowering. Furthermore, the lifting and lowering of the robotic arm does not affect the rotation of the fire hydrant shell it grips. This facilitates heat exchange between the water sources inside the quenching water tank during quenching, improving quenching efficiency. Additionally, the synchronous lifting and lowering of the filter screen facilitates the cleaning of slag generated during quenching. Attached Figure Description

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] Obviously, many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Please see Figure 1-3This utility model provides a heat treatment device for fire hydrant castings, including a quenching water tank 1. A side plate 2 is fixedly connected to the top of the quenching water tank 1, and a second opening 18 is formed on the outer surface of the side plate 2. An electric cylinder 7 is fixedly inserted into the top of the quenching water tank 1, and a lifting sleeve block 8 is fixedly connected to the top of the electric cylinder 7. A top plate 3 is fixedly connected to the top of the side plate 2, and a first opening 6 is formed on the outer surface of the top plate 3. A sliding mechanism is provided inside the first opening 6, and a sliding insert plate 5 is provided on the sliding mechanism. A first servo motor 4 is fixedly connected to the top of the sliding insert plate 5. A rotating column 10 is fixedly connected to the output shaft. A connecting plate 11 is slidably inserted into the interior of the rotating column 10. A connecting post 23 is fixedly sleeved on the outer surface of the bottom end of the connecting plate 11. A connecting member 9 is rotatably connected to the outer surface of the connecting post 23 via a bearing. One end of the connecting member 9 is slidably inserted into the interior of the lifting sleeve block 8. A robotic arm 13 is provided at the bottom end of the connecting plate 11. A connecting block 16 is fixedly connected to the bottom of the lifting sleeve block 8, and a filter screen plate 14 is fixedly connected to the bottom of the connecting block 16. By extending and retracting the electric cylinder 7, the lifting sleeve block 8 can be used to drive the connecting member 9 to move up and down, thereby... The lifting and lowering of the robotic arm 13 facilitates the placement and removal of the fire hydrant casing. During this process, the insert plate 11 can slide and rise within the rotating column 10. The sliding mechanism allows the sliding plate 5 to be moved to either directly above or to one side of the quenching water tank 1, further facilitating the placement and removal of the fire hydrant casing. When the fire hydrant casing is positioned directly above the quenching water tank 1, the first servo motor 4 is activated, causing the rotating column 10 to rotate the insert plate 11. This, in turn, allows the robotic arm 13 to rotate the fire hydrant casing. When the lifting sleeve 8 descends, placing the fire hydrant casing inside the quenching water tank 1, [further details about the lifting and lowering mechanism are needed]. The rotation of the robotic arm 13 allows for heat exchange within the water source during quenching of the fire hydrant casing. This facilitates temperature reduction and prevents the water source near the casing from becoming too hot while the water source outside remains cool, resulting in slower temperature exchange and lower quenching efficiency. Simultaneously, the filter screen 14 at the bottom of the connecting block 16 lowers during quenching to filter out any debris that may appear. Once quenching is complete, the filter screen 14 rises to remove debris from the outside of the quenching water tank 1, facilitating cleaning and preventing sedimentation inside the quenching water tank 1.

[0020] It should be noted that the sliding mechanism mentioned above includes the second servo motor 20. When the second servo motor 20 is turned on, the rotation of the screw 22 inside a groove on one side of the first opening 6 drives the sliding plate 5 to slide and adjust inside the first opening 6, while the insertion post 21 inside another groove provides limiting support.

[0021] In order to limit the sliding position of one end of the connector 9 inside the lifting sleeve block 8, a limiting piece 17 is fixedly connected to one end of the connector 9, and one side of the limiting piece 17 is in contact with one end of the lifting sleeve block 8.

[0022] Furthermore, in order to facilitate the exchange of water inside the quenching water tank 1, an inlet 19 is provided on one side of the quenching water tank 1, and an outlet 15 is provided on the other side of the inlet 19. The inlet 19 is located on one side of the electric cylinder 7 and above the outlet 15.

[0023] Furthermore, in order to facilitate the lifting and lowering of the filter screen plate 14 and thus filter out the slag that may occur during quenching, the plug-in 9 can ensure the rotation of the robot arm 13 while it is lifting and lowering. The plug-in 9 is Z-shaped, and one end of the plug-in 9 is respectively attached to the two sides of the inner cavity of the lifting sleeve block 8. The height of the end of the plug-in 9 on one side of the lifting sleeve block 8 is higher than the height of the end of the plug-in 9 on the sleeve post 23.

[0024] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0025] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0026] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
