Description

Technical Field

[0001] This utility model relates to the field of metallurgical technology, and more specifically, to a fully automatic temperature measurement and sampling robot for molten steel. Background Technology

[0002] In the steelmaking industry, steelmaking is the key step in converting molten iron into qualified steel. Ensuring that the molten steel meets quality standards and satisfies the performance requirements of subsequent rolling and product use is the core objective of the steelmaking process. Among these processes, the furnace-front temperature measurement and sampling procedures, as an indispensable core link in the steelmaking process, play a decisive role in steel quality control and process optimization. In actual steelmaking production, workers need to use specialized equipment to monitor the temperature of molten steel in the furnace and collect samples. On the one hand, temperature monitoring can accurately obtain the current thermal state parameters of the molten steel, which are directly related to the fluidity of the molten steel, the rate of chemical reaction, and the setting of process parameters for subsequent refining, casting, and other processes. If the temperature of the molten steel is not accurately controlled, it may lead to problems such as poor refining effect, steel leakage during casting, or defects in the quality of the cast billet. On the other hand, by performing composition analysis on the collected molten steel samples, the content of key alloying elements such as carbon, silicon, phosphorus, and sulfur, as well as harmful elements, in the molten steel can be clearly identified. These compositional data are the core basis for judging whether the molten steel meets the composition requirements of the target steel grade, and are also an important support for subsequent operations such as adjusting the amount of slag-forming agent added and alloying process parameters.

[0003] Currently used fully automated steel temperature measurement and sampling robots are mostly composed of simple components such as robotic arms and sampling rods, and can only perform a single sampling and temperature measurement function. Furthermore, after the sampling rod is removed from the high-temperature molten steel, its surface is prone to molten steel residue, which is easily oxidized when exposed to air. The accumulation of residue on the sampling rod affects the accuracy of subsequent sampling and requires manual cleaning, increasing labor costs and operation time. On the other hand, the sampling rod is usually fixedly connected to the main body of the device. When the sampling rod is damaged or needs to be replaced with a different specification, the disassembly process is cumbersome and requires specialized tools, reducing the maintenance efficiency and operational flexibility of the device. Therefore, a fully automated steel temperature measurement and sampling robot is proposed to solve the above problems. Utility Model Content

[0004] To address the aforementioned technical problems, a fully automated steel temperature measurement and sampling robot is provided. This invention utilizes a protective shell and scraper ring to automatically clean residue and prevent oxidation, and allows for quick replacement of the sampling rod through disassembly of components.

[0005] To achieve the above objectives, this utility model provides a fully automatic temperature measurement and sampling robot for molten steel, comprising: a sampling rod, a telescopic rod at the top of the sampling rod, a fixed plate fixedly connected to the top of the telescopic rod, a protective shell fixedly connected to the bottom of the fixed plate, a scraper ring fixedly connected to the inner side of the protective shell, a sealing frame fixedly connected to the outer shaft of the protective shell, a sealing cover rotatably connected to the bottom of the sealing frame, a wooden handle fixedly connected to the outer side of the sealing cover, a locking block fixedly connected to the top of the sampling rod, and a disassembly assembly inside the telescopic rod.

[0006] Furthermore, the disassembly assembly includes a spring rod, which is fixedly connected inside the telescopic rod, and two locking plates are fixedly connected to the bottom of the telescopic rod.

[0007] Furthermore, two lifting rods are fixedly connected to the top of the fixed plate, and an adjustment seat is fixedly connected to the top of the lifting rods.

[0008] Furthermore, a temperature sensor is fixedly connected to one side of the adjustment seat, and a signal transmitter is fixedly connected to the top of the temperature sensor.

[0009] Furthermore, a robotic arm is rotatably connected to the other side of the adjustment seat, and a rotating base is rotatably connected to the bottom of the robotic arm.

[0010] Furthermore, a base is fixedly connected to the bottom of the rotating seat, and a steel pool is fixedly connected to the top of the base.

[0011] Furthermore, a sample receiving frame is rotatably connected to the top of the base, and multiple sample receiving tubes are installed on the outer periphery of the sample receiving frame.

[0012] Furthermore, a data transmitter is fixedly connected to the top of the base, a signal receiver is fixedly connected to the top of the data transmitter, and multiple casters are provided at the bottom of the base.

[0013] By adopting the above technical solution, this utility model has the following advantages compared with the prior art: 1. This utility model provides a fully automatic steel temperature measurement and sampling robot. The protective shell effectively protects the sampling rod, reducing its air exposure area to lower the probability of oxidation, delaying wear, and extending its lifespan. Its inner scraper ring automatically scrapes away surface slag during the extension and retraction of the sampling rod, preventing it from affecting subsequent sampling accuracy. No manual cleaning is required, reducing manpower and improving operational convenience and efficiency. Furthermore, the sealing frame and cover connected to the outer shaft of the protective shell cooperate to close the opening of the protective shell when not in use, further isolating air and impurities. This strengthens the anti-oxidation protection of the sampling rod and prevents impurities from affecting the cleaning effect of the scraper ring.

[0014] 2. This utility model provides a fully automatic steel temperature measurement and sampling robot. The disassembly components allow for convenient assembly and disassembly of the sampling rod and the telescopic rod. When the sampling rod is worn due to long-term contact with high-temperature molten steel, or when it needs to be replaced with different specifications to adapt to various steel temperature measurement and sampling scenarios, no special tools are required. The spring rod and the clamping plate can be used for quick assembly and disassembly, greatly simplifying the process and improving the efficiency of component replacement and maintenance. At the same time, the spring rod can provide stable elastic support for the clamping plate, ensuring that the connection between the two is firm and preventing the components from loosening during sampling, which would affect the accuracy of temperature measurement and sampling, thus balancing convenience and stability.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0021] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of the invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale.

[0024] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0025] like Figures 1 to 2As shown, this utility model provides a fully automatic steel temperature measurement and sampling robot, including: a sampling rod 1, with a telescopic rod 2 at the top of the sampling rod 1. The sampling rod 1 is the core component that directly contacts the molten steel to complete sample collection. The telescopic rod 2 at its top can be adjusted in length to flexibly adapt to the steel temperature measurement and sampling needs at different depths and positions, avoiding the problem of inaccurate sampling position or inability to reach the target molten steel layer due to fixed length limitations. A fixing plate 3 is fixedly connected to the top of the telescopic rod 2. The fixing plate 3 at the top of the telescopic rod 2 plays a connecting role, on the one hand, it can stably bear the telescopic force transmitted by the telescopic rod 2, and on the other hand, it provides a stable installation foundation for the installation of components such as the protective shell 4 below. To ensure that the components do not shift position due to vibration or external force during operation, a protective shell 4 is fixedly connected to the bottom of the fixing plate 3. The protective shell 4 is a key structure for protecting the sampling rod 1. It can cover most of the sampling rod 1, reducing the contact area between the sampling rod 1 and the air, and reducing the probability of wear and tear due to oxidation when the sampling rod 1 is not in operation. At the same time, it can also prevent external impurities from adhering to the surface of the sampling rod 1. A scraper ring 5 is fixedly connected to the inside of the protective shell 4. The scraper ring 5 is made of wear-resistant and high-temperature resistant material. When the sampling rod 1 retracts upward into the protective shell 4 after completing the molten steel sampling, the scraper ring 5 can closely fit the surface of the sampling rod 1 and automatically scrape off the residual molten steel residue on the sampling rod 1, avoiding the accumulation of residue and affecting subsequent operations. The sampling accuracy is improved, eliminating the need for manual cleaning and saving labor costs. A sealing frame 23 is fixedly connected to the outer shaft of the protective shell 4. The sealing frame 23 is the supporting structure for mounting the cover 6. It provides a stable fulcrum for the cover 6's rotation, ensuring smooth opening and closing. Simultaneously, the sealing frame 23 enhances the overall structural strength of the protective shell 4, preventing deformation due to external impacts. The cover 6 is rotatably connected to the bottom of the sealing frame 23. When the device is idle, the cover 6 can be closed to seal the opening of the protective shell 4, further preventing air, dust, and other impurities from entering the interior of the protective shell 4. This provides double protection for the sampling rod 1, preventing oxidation and corrosion from long-term exposure to air. During device operation... The cover 6 can be opened without affecting the telescopic sampling action of the sampling rod 1. A wooden handle 7 is fixedly connected to the outside of the cover 6. The wooden handle 7 has good heat insulation performance. Since the working environment of the device is close to the high temperature molten steel, the surface of the cover 6 may generate a certain amount of heat. The wooden handle 7 can prevent the operator from being burned when opening and closing the cover 6. A locking block 8 is fixedly connected to the top of the sampling rod 1. The locking block 8 is the key component for connecting and fixing the sampling rod 1 and the telescopic rod 2. The locking block 8 can cooperate with the disassembly component inside the telescopic rod 2. The locking structure can stably fix the sampling rod 1 on the telescopic rod 2, preventing the sampling rod 1 from falling off or loosening during the sampling process, and ensuring that the sampling work is carried out stably. The telescopic rod 2 is equipped with a disassembly component.

[0026] Reference Figure 1 and Figure 3The disassembly assembly includes a spring rod 9, which is used to buffer the sampling rod 1 when it is replaced. The spring rod 9 is fixedly connected inside the telescopic rod 2. Two locking plates 10 are fixedly connected to the bottom of the telescopic rod 2. The locking plates 10 are used to lock the locking block 8 at the top of the sampling rod 1 when the sampling rod 1 is buffered outward by the spring rod 9, so as to achieve disassembly and fixation.

[0027] Reference Figure 1 , Figure 4 and Figure 5Two lifting rods 11 are fixedly connected to the top of the fixed plate 3. The lifting rods 11 are made of high-strength metal material, with good load-bearing capacity and lifting stability. They can drive the fixed plate 3 and the sampling rod 1, protective shell 4 and other components below to lift as a whole, thereby adjusting the depth of the sampling rod 1 into the molten steel to meet the temperature measurement and sampling requirements of different molten steel layers. An adjustment seat 12 is fixedly connected to the top of the lifting rod 11. The adjustment seat 12 is the core adjustment and connection component of the device. On the one hand, it can stably bear the lifting power transmitted by the lifting rod 11, ensuring that the lifting action is smoothly transmitted to the components below. A thermometer 13 is fixedly connected to one side of the adjustment seat 12. The thermometer 13 is a device specifically used to detect the temperature of molten steel. It has the characteristics of high precision and high temperature resistance. While the sampling rod 1 is inserted into the molten steel for sampling, the thermometer 13 can simultaneously contact the steel. The temperature data of molten steel is obtained through water or sensing to provide accurate temperature basis for subsequent steelmaking process adjustments, ensuring that the molten steel quality meets the requirements. A signal transmitter 14 is fixedly connected to the top of the temperature sensor 13. The signal transmitter 14 can convert the molten steel temperature data detected by the temperature sensor 13 into a wireless signal in real time and send it to the signal receiver 21 on the top of the data instrument 20. A robotic arm 15 is rotatably connected to the other side of the adjustment seat 12. The robotic arm 15 has multi-degree-of-freedom rotation capability. It can flexibly adjust the position and angle of the adjustment seat 12 and the components below it, so that the sampling rod 1 can be accurately aligned with the target sampling point in the molten steel pool 18. It can adapt to molten steel pools 18 of different shapes and positions, improving the versatility and sampling flexibility of the device. A rotating base 16 is rotatably connected to the bottom of the robotic arm 15. The rotating base 16 can achieve 360 ​​degrees. The rotating base 16 rotates to rotate the robotic arm 15, the adjusting seat 12 above it, the sampling rod 1, and other components, further expanding the sampling range of the device. This allows the device to measure and sample the temperature of molten steel in different areas of the molten steel tank 18, ensuring that the obtained molten steel data is representative. A base 17 is fixedly connected to the bottom of the rotating base 16. The base 17 is the supporting foundation of the entire device, made of a heavy-duty and stable metal structure, providing stable support for all components. A molten steel tank 18 is fixedly connected to the top of the base 17. The molten steel tank 18 is a container for holding the molten steel to be sampled and is made of special high-temperature and corrosion-resistant steel. A sample collection frame 19 is rotatably connected to the top of the base 17. 19 is a structure used to store the sample after sampling. Its position can be adjusted by rotation, making it convenient for operators to place the molten steel sample collected by the sampling rod 1 into the sample receiving tube 24. At the same time, the rotating design of the sample receiving rack 19 also makes it easy for operators to pick up and put down the sample from different angles, improving the convenience of sample collection and preventing the sample from spilling during the transfer process. Multiple sample receiving tubes 24 are installed on the outer periphery of the sample receiving rack 19. The sample receiving tubes 24 are made of high-temperature resistant glass or metal. Each sample receiving tube 24 can store one molten steel sample, which is convenient for distinguishing and storing samples collected at different times and locations. The data instrument 20 is fixedly connected to the top of the base 17. The data instrument 20 is the data processing and storage center of the device.It can receive molten steel temperature data transmitted by the signal receiver 21, and also record information such as the time and location of each sampling. It organizes, analyzes, and stores the data, facilitating subsequent review and analysis of the molten steel data by staff. The signal receiver 21 is fixedly connected to the top of the data instrument 20. The signal receiver 21 is matched with the signal transmitter 14 on the top of the temperature sensor 13, specifically used to receive the wireless signal of molten steel temperature sent by the signal transmitter 14, and convert the received signal into an electrical signal recognizable by the data instrument 20, ensuring accurate and rapid transmission of temperature data to the data instrument 20. The base 17 has multiple casters 22 at its bottom, providing flexible steering and movement capabilities, allowing operators to easily move the device within the steelmaking workshop.

[0028] Working principle: During the initial preparation stage, the device is moved to the designated position in front of the steelmaking furnace by the casters 22 at the bottom of the base 17, ensuring that the molten steel pool 18 is aligned with the area of ​​molten steel to be sampled for temperature measurement. The operator opens the cover 6 through the wooden handle 7, so that the protective shell 4 is open. At the same time, the data instrument 20 is started, and the signal receiver 21 on its top is put into the receiving state. The temperature sensor 13 is powered on and preheated to ensure the accuracy of subsequent temperature detection. In the position adjustment stage, according to the position and depth of the molten steel in the molten steel pool 18, the robotic arm 15 rotates around the rotating base 16 in multiple degrees of freedom to adjust the horizontal position of the adjusting base 12. The two lifting rods 11 at the bottom of the adjusting base 12 extend and retract synchronously, pushing the adjustment base 12 to adjust the horizontal position of the adjusting base 12. The fixed plate 3 and the telescopic rod 2 and sampling rod 1 below it are raised and lowered as a whole until the sampling rod 1 is accurately aligned with the target molten steel layer to complete the position calibration before sampling. During the temperature measurement and sampling stage, the telescopic rod 2 extends downward to drive the sampling rod 1 through the opening of the protective shell 4 and into the molten steel in the molten steel pool 18. At this time, the temperature sensor 13 on one side of the adjusting seat 12 simultaneously contacts the molten steel and detects the temperature in real time. The detected temperature data is converted into a wireless signal by the signal transmitter 14 on the top of the temperature sensor 13 and sent to the signal receiver 21 on the top of the data instrument 20. The signal receiver 21 converts the signal into an electrical signal and transmits it to the data instrument 20. The data instrument 20 records and stores the temperature data in real time. The sampling rod 1 remains in the molten steel for a preset time. After the sample collection is completed, the telescopic rod 2 retracts upward, causing the sampling rod 1 to detach from the molten steel and return to the protective shell 4. During the residue cleaning and protection stage, as the sampling rod 1 retracts upward under the action of the telescopic rod 2, the scraper ring 5 on the inner side of the protective shell 4 closely adheres to the surface of the sampling rod 1, automatically scraping away the molten steel residue adhering to its outer wall, preventing residue accumulation from affecting the subsequent sampling accuracy. After the residue cleaning is completed, the operator closes the sealing cover 6 using the wooden handle 7. The sealing cover 6, supported by the sealing frame 23, seals the opening of the protective shell 4, reducing the contact area between the sampling rod 1 and the air to reduce its oxidation loss probability. During the sample transfer stage, the robotic arm 15 readjusts its position again, moving the sampling rod 1 above the sample receiving frame 19. The operator then controls the sampling rod to be transferred. The sample rod 1 releases the molten steel sample and injects it into one of the sample collection tubes 24 on the outer periphery of the sample collection frame 19, completing a single sample transfer. During component maintenance and replacement, when the sampling rod 1 is damaged or needs to be replaced with a different specification, the disassembly assembly inside the telescopic rod 2 is used. The spring rod 9 inside the telescopic rod 2 provides elastic support. Pressing the spring rod 9 can loosen the two locking plates 10 at the bottom of the telescopic rod 2 from fixing the locking block 8 at the top of the sampling rod 1. At this time, the sampling rod 1 can be directly removed. After replacing the new sampling rod 1, the spring rod 9 is released, and the locking plates 10 re-lock the locking block 8 under the elastic action of the spring rod 9, completing the quick disassembly and assembly of the sampling rod 1 without the need for special tools, improving maintenance efficiency and the flexibility of device use.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it.
