Description

Technical Field

[0001] This utility model relates to the field of high-temperature furnace transportation technology, and in particular to a heavy-duty automatic transportation device for high-temperature furnaces. Background Technology

[0002] A high-temperature furnace is a furnace capable of reaching extremely high temperatures for processes such as heating, smelting, heat treatment, or chemical reactions. High-temperature furnaces are widely used in industries such as metallurgy, materials science, and chemical engineering, especially when heating and processing materials such as metals, ceramics, glass, and ores is required.

[0003] Heavy-duty automated transport systems for high-temperature furnaces are commonly used in high-temperature environments in industrial production, particularly in metallurgy, chemical engineering, and power generation, for transporting materials inside or around high-temperature furnaces. These systems require high temperature resistance, high load-bearing capacity, high stability, and automated control. Heavy-duty automated transport systems for high-temperature furnaces (such as slag transport vehicles and automated trailer systems) are widely used in high-temperature smelting processes in steel mills and other similar facilities. Their primary task is to automatically and efficiently transport slag, molten steel, or other high-temperature materials from the furnace to designated processing, storage, or disposal areas. The design of these systems typically considers the special requirements of high temperature, heavy load, and complex working environments. With technological advancements, modern heavy-duty automated transport systems for high-temperature furnaces can integrate multiple functions, further improving their efficiency, accuracy, and safety.

[0004] In metallurgical processes, high-temperature slag is generated, requiring timely transfer and disposal of the slag from high-temperature furnaces. However, existing heavy-duty automatic conveying devices for high-temperature furnaces often lack the ability to cover the furnace opening when transporting molten slag. This can lead to slag splashing during transport, or other objects falling into the hot, liquid slag, creating a hazard of hot, liquid slag splashing and posing safety risks to equipment operators. High-temperature liquid slag not only easily causes burns but can also lead to serious accidents such as fires and explosions.

[0005] In summary, the existing technology lacks a technique for covering the furnace opening when transporting a high-temperature furnace containing liquid slag. Summary of the Invention

One end of the lifting plate is in movable contact with the outer wall of the high-temperature furnace, and an electric push rod A is fixedly connected to the other end of the lifting plate. The other end of the electric push rod A is fixedly connected to the inner wall of the movable seat.

[0009] Preferably, the guardrail is slidably fitted with an arc-shaped frame, a movable railing is fixedly connected to the arc-shaped frame, a motor is fixedly connected to one end of the movable railing, a drive wheel is fixedly connected to the output end of the motor, and an arc-shaped rack A is fixedly connected to the guardrail, the arc-shaped rack A is meshed with the drive wheel for transmission.

[0011] Preferably, a gear is fixedly connected to one end of the rotating frame and the fixed frame, the gear meshes with a rack for transmission, and a limit rod is fixedly connected to the rotating frame, the top of the limit rod being inclined.

[0012] Preferably, both ends of the splash guard are fixedly connected to sliders, which are slidably engaged with the inner wall of the rotating frame. One side of the splash guard is in movable contact with the opening of the high-temperature furnace. An exhaust hole is provided through the middle of the splash guard. A contact rod is slidably engaged with one side of the splash guard. A cleaning sleeve is fixedly connected to one end of the contact rod. The cleaning sleeve is slidably engaged with the inner wall of the exhaust hole. A spring is fixedly connected inside the cleaning sleeve. The other end of the spring is fixedly connected to the splash guard. The other end of the contact rod is in slidable contact with a limiting rod.

[0013] Preferably, the transmission mechanism includes a threaded rod, which is rotatably connected to the inner wall of the rotating frame. The threaded rod is threadedly connected to one of the sliders. An adjusting wheel is fixedly connected to the bottom end of the threaded rod. The adjusting wheel is meshed with an arc-shaped rack B. A driving wheel is fixedly connected to the middle of the threaded rod. A transmission wheel is meshed with one side of the driving wheel. The transmission wheel is rotatably connected to the rotating frame.

[0014] Preferably, a driven wheel is meshed with one side of the transmission wheel, and a transmission rod is fixedly connected to the driven wheel. The transmission rod is rotatably connected to the rotating frame, and the top end of the transmission rod has an L-shaped structure.

[0016] Compared with the prior art, the present invention has the following beneficial effects: When transporting a high-temperature furnace containing high-temperature liquid slag, a rotating frame can be used to move a splash guard to cover the furnace opening, effectively preventing slag from splashing out, reducing the risk of accidents, preventing external objects from entering the furnace, and protecting the safety of the materials and equipment inside the furnace. This also prevents slag from splashing out during transport or other objects from falling into the high-temperature liquid slag. At the same time, vent holes are opened on the splash guard to prevent gas from accumulating or becoming too high in pressure inside the furnace, effectively releasing the gas inside the furnace and avoiding safety problems caused by gas expansion. By installing a slag scraper, the slag scraper can be moved back and forth rapidly while the transmission mechanism retracts the splash cover, scraping off the slag adhering to the splash cover. This greatly reduces manual cleaning work, improves production efficiency, and ensures that the splash cover always maintains a good working condition. At the same time, by installing a cleaning sleeve, the cleaning sleeve can clean the inner wall of the exhaust port on the splash cover while it is being retracted, preventing gas exhaust from being blocked, ensuring a stable atmosphere inside the furnace, helping to reduce equipment failure rate and maintenance costs, and extending the service life of the equipment. By setting up protective railings and movable barriers, the high-temperature furnace containing high-temperature liquid slag can be blocked around the furnace during transport, isolating the high-temperature area and preventing nearby workers from getting close or misoperating, thus reducing the risk of high-temperature burns and other accidents.

Detailed Implementation

[0019] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0020] like Figures 1-9The high-temperature furnace heavy-duty automatic transport device shown includes a transport base 1, a plurality of lifting mechanisms 2 fixedly connected to the transport base 1, a high-temperature furnace 3 arranged on one side of the transport base 1, a guardrail 4 fixedly connected to the transport base 1, a fixed frame 5 fixedly connected to the transport base 1, a rotating frame 6 rotatably connected to the fixed frame 5, a splash guard 7 slidably fitted on the rotating frame 6, a transmission mechanism 8 rotatably connected to the rotating frame 6, and a slag scraper 9 slidably fitted on the rotating frame 6.

[0021] like Figure 3 As shown, the lifting mechanism 2 includes a hydraulic cylinder 201, which is fixedly connected to the towing seat 1. A movable seat 202 is fixedly connected to the output end of the hydraulic cylinder 201. A lifting plate 203 is slidably mounted on the movable seat 202. One end of the lifting plate 203 is in movable contact with the outer wall of the high-temperature furnace 3, and the other end of the lifting plate 203 is fixedly connected to an electric actuator A204. The other end of the electric actuator A204 is fixedly connected to the inner wall of the movable seat 202. The electric actuator A204 drives the connected lifting plate 203 to approach and contact the high-temperature furnace 3, and then the hydraulic cylinder 201 drives the lifting plate 203 to move upward, thereby lifting the high-temperature furnace 3.

[0022] like Figure 4 As shown, an arc-shaped frame 401 is slidably mounted on the protective railing 4. A movable railing 402 is fixedly connected to the arc-shaped frame 401. A motor 403 is fixedly connected to one end of the movable railing 402, and a drive wheel 404 is fixedly connected to the output end of the motor 403. An arc-shaped rack A405 is fixedly connected to the protective railing 4, and the arc-shaped rack A405 meshes with the drive wheel 404 for transmission. The motor 403 drives the connected drive wheel 404 to rotate, so that the drive wheel 404 can mesh with the arc-shaped rack A405, causing the arc-shaped frame 401 to move, and the movable railing 402 to move out, thus forming a barrier around the high-temperature furnace 3 with the protective railing 4.

[0023] like Figure 5 As shown, an electric actuator B501 is fixedly connected to one end of the fixed frame 5, and a rack 502 is fixedly connected to the output end of the electric actuator B501. An arc-shaped rack B503 is fixedly connected to the other end of the fixed frame 5. The electric actuator B501 drives the connected rack 502 to move, and at this time the rack 502 will drive the rotating frame 6 connected to the gear 601 to rotate and lower.

[0024] like Figure 6 As shown, a gear 601 is fixedly connected to one end of the rotating frame 6 and the fixed frame 5. The gear 601 meshes with the rack 502 for transmission. A limit rod 602 is fixedly connected to the rotating frame 6. The top of the limit rod 602 is inclined.

[0025] like Figure 7As shown, both ends of the splash guard 7 are fixedly connected to sliders 701, which slide in cooperation with the inner wall of the rotating frame 6. One side of the splash guard 7 is in contact with the opening of the high-temperature furnace 3. An exhaust hole 702 is opened through the middle of the splash guard 7. A contact rod 703 is slidably connected to one side of the splash guard 7. A cleaning sleeve 704 is fixedly connected to one end of the contact rod 703.

The other end of the spring 705 is fixedly connected to the splash guard 7. The other end of the contact rod 703 slides in contact with the limiting rod 602. When the splash guard 7 moves down, the contact rod 703 contacts the limiting rod 602, thereby driving the connected cleaning sleeve 704 to insert into the exhaust hole 702 to clean the slag adhering to the exhaust hole 702.

[0026] like Figure 8 As shown, the transmission mechanism 8 includes a threaded rod 801, which is rotatably connected to the inner wall of the rotating frame 6. The threaded rod 801 is threadedly connected to one of the sliders 701. An adjusting wheel 802 is fixedly connected to the bottom end of the threaded rod 801, and the adjusting wheel 802 meshes with an arc-shaped rack B503 for transmission. A drive wheel 803 is fixedly connected to the middle of the threaded rod 801, and a transmission wheel 804 is meshed with one side of the drive wheel 803 for transmission. The transmission wheel 804 is rotatably connected to the rotating frame 6. When the rotating frame 6 rotates and stands upright, the arc-shaped rack B503 will drive the adjusting wheel 802 to rotate, which in turn will drive the connected threaded rod 801 to rotate, allowing the threaded rod 801 to move the splash guard 7 connected to the slider 701 downwards.

[0027] A driven wheel 805 is meshed with one side of the transmission wheel 804. A transmission rod 806 is fixedly connected to the driven wheel 805 and rotatably connected to the rotating frame 6. The top of the transmission rod 806 has an L-shaped structure. The threaded rod 801 can drive the connected driving wheel 803 to rotate, so that the driving wheel 803 can drive the transmission wheel 804 to rotate, so that the transmission wheel 804 can drive the driven wheel 805 to rotate, so that the driven wheel 805 can drive the transmission rod 806 to rotate. At this time, the L-shaped structure at the other end of the transmission rod 806 will slide within the fixed frame 901, thereby driving the slag scraper 9 connected to the fixed frame 901 to reciprocate.

[0028] like Figure 9 As shown, the slag scraper 9 is slidably contacted with one side of the splash cover 7. The slag scraper 9 has a sawtooth structure. One end of the slag scraper 9 is connected and fixedly installed with a fixing frame 901. The inner wall of the fixing frame 901 is slidably engaged with the outer wall of the top of the transmission rod 806.

[0029] Working principle: When it is necessary to transport the high-temperature furnace 3 containing high-temperature liquid slag, the towing seat 1 is moved so that the lifting mechanism 2 is located around the high-temperature furnace 3. Then, the electric push rod A204 drives the connected lifting plate 203 to approach and contact the high-temperature furnace 3. Then, the hydraulic cylinder 201 drives the lifting plate 203 to move upward, thereby lifting the high-temperature furnace 3. Then, the motor 403 drives the connected drive wheel 404 to rotate, so that the drive wheel 404 can mesh with the arc-shaped rack A405, causing the arc-shaped frame 401 to move, causing the movable railing 402 to move out and cooperate with the guardrail 4 to block around the high-temperature furnace 3. Then, the electric actuator B501 drives the connected rack 502 to move. At this time, the rack 502 will drive the rotating frame 6 connected to the gear 601 to rotate and fall down, so that the splash cover 7 covers the furnace mouth of the high temperature furnace 3. At this time, under the action of the spring 705, the connected cleaning sleeve 704 will be moved out from the exhaust hole 702, so that the splash cover 7 can ensure the stable air pressure in the high temperature furnace 3 when in use. After the towing is completed, the rotating frame 6 is rotated and erected. At this time, under the action of the arc rack B503, the adjusting wheel 802 will be driven to rotate, so that the adjusting wheel 802 can drive the connected threaded rod 801 to rotate, so that the threaded rod 801 can drive the splash cover 7 connected to the slider 701 to move down. At this time, the threaded rod 801 can drive the connected driving wheel 803 to rotate, so that the driving wheel 803 can drive the transmission wheel 804 to rotate, so that the transmission wheel 804 can drive the driven wheel 805 to rotate, so that the driven wheel 805 can drive the transmission rod 806 to rotate. At this time, the L-shaped structure at the other end of the transmission rod 806 will slide in the fixed frame 901, thereby driving the slag scraper 9 connected to the fixed frame 901 to move back and forth, thereby scraping off the slag attached to the splash cover 7. At the same time, when the splash cover 7 moves down, the contact rod 703 will contact the limit rod 602, thereby driving the connected cleaning sleeve 704 to be inserted into the exhaust hole 702 to clean the slag attached to the exhaust hole 702 and ensure its exhaust efficiency.
