Description

Technical Field

[0001] This invention relates to the field of metallurgical equipment technology, specifically to an intelligent automated ladle-turning gantry crane. Background Technology

[0002] With the deep integration of new-generation information technologies such as 5G, big data, industrial internet, cloud computing, and artificial intelligence with industry and the economy, digital transformation has become a primary and unavoidable issue for enterprises. Currently, slag ladle transportation and turning operations in smelters use slag ladle cars. However, with the automation and intelligent upgrading of equipment in the copper industry, various smelters have successively adopted different operational methods, such as diesel locomotive transfer of slag ladles, electric flatcar transfer of slag ladles, and gantry crane turning. Compared with intelligent rail transportation, the existing slag ladle car transportation has the following problems: 1. The operating and maintenance costs of slag caravans are high; 2. The large operating radius and wide operating channel of the slag bag car result in an insufficient number of slag bags to be placed in the slow cooling slag yard (198 slag bag positions). Currently, the average slow cooling time of the second series flash furnace slag is only 38-42 hours, and the average slow cooling time of the second series converter slag is only 64-68 hours, which fails to reach the industry average of 80 hours.

[0003] 3. The operation of slag trucks causes significant damage to the road surface and requires regular repairs.

[0004] Research shows that in recent years, many newly built copper smelting enterprises have adopted RGV electric carts, gantry cranes, and remote control facilities to replace traditional slag ladle operations, achieving both safe production and automation. The necessity of optimizing and upgrading the slag ladle transfer system: 1. The slag baggage car is diesel-powered, which consumes more energy and has higher operating costs compared to the electric-powered RGV flatcar. 2. Currently, the slag bag slow cooling time in the slow cooling field of the Guiye No. 2 system is insufficient, which increases the probability of red bags (safety hazard) and weakens the recrystallization effect of copper during slow cooling, affecting the copper recovery rate in the beneficiation process. After the renovation, the number of slag bag positions in the slow cooling field will increase to 320, and the slow cooling field will have the ability to increase the slow cooling time to 80 hours.

[0005] 3. The operation of slag bag trucks causes significant wear and tear on the road surface. The cooling water sprayed from the slag bags and the slag leachate are weakly acidic and contain small amounts of heavy metals. These can seep into the ground along localized cracks in the concrete surface of the slag cooling pad, causing pollution. According to environmental protection requirements, it is essential to lay an HDPE geomembrane under the concrete structure layer during the design of the slag cooling pad. Research revealed that due to insufficient public awareness of environmental protection in the early stages, the existing slag cooling pad does not have a geomembrane. Adding a geomembrane later would be too costly, making it impossible to stop soil and groundwater pollution. With the increasing national environmental protection requirements (GB / T50934-2013 Technical Specification for Seepage Prevention in Petrochemical Engineering), it is necessary to add seepage prevention works to the slag cooling pad at the initial design stage of this upgrade project to address this historical issue.

[0006] Based on considerations of controlling metallurgical production costs, addressing operational safety and environmental issues, and upgrading operational automation, and drawing on the production experience of peer companies, it is proposed to optimize and upgrade the industry's existing slag bag transfer system. Summary of the Invention

[0007] This invention addresses the technical problems existing in the prior art by providing an intelligent automated bag-flipping gantry crane.

[0008] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A smart automated bag-turning gantry crane includes a frame and a bag-turning device. The bag-turning device includes a hook mechanism and a support-turning mechanism. The support-turning mechanism is installed at one end of the frame. The hook mechanism is installed on the frame and can reciprocate along the direction from one end of the frame to the other. It is used to lift and transport slag bags and send the slag bags to the support-turning mechanism, while cooperating with the support-turning mechanism to turn the slag bags.

[0009] The beneficial effects of this invention are: during the operation, the slag bag is sent to the support and turning mechanism through the plate hook mechanism, and at the same time, the plate hook mechanism cooperates with the support and turning mechanism to turn the slag bag over, so as to complete the dumping of the slag inside the slag bag. The dumping is convenient, efficient, safe and reliable.

[0010] This invention has a compact structure and reasonable design, which can realize the stable conveying and turning of slag bags during metallurgical operations, with high operating efficiency. The slag dumping is relatively concentrated, which facilitates subsequent centralized processing and is safe and reliable.

[0011] Based on the above technical solution, the present invention can be further improved as follows.

[0012] Furthermore, the support and tilting mechanism includes a support frame and a tilting disc. The support frame is mounted on the frame and can swing back and forth. The tilting disc is mounted on the support frame and can tilt up and down to support and hook the slag bag.

[0013] The beneficial effect of adopting the above-mentioned further solution is that during the operation, the slag bag is sent to the tilting plate by the plate hook mechanism, and at the same time, the plate hook mechanism drives the slag bag and the tilting plate to rotate together to complete the dumping of the slag in the slag bag. The dumping is convenient, efficient, safe and reliable.

[0014] Furthermore, the support frame includes a support plate and two hanging rods, which are arranged opposite to each other and their upper ends are rotatably connected to the frame; the support plate is distributed between the lower ends of the two hanging rods and its two ends are rotatably connected to the lower ends of the two hanging rods; the tilting disc is mounted on the support plate.

[0015] The advantages of adopting the above-mentioned further solution are that the structure is simple, the support frame is more reasonable by using a support plate and two hanging rods, and the support plate, the two hanging rods and the frame form a parallelogram during the slag bag tilting process, which ensures the stable tilting of the slag bag and is safer and more reliable.

[0016] Furthermore, the support flipping mechanism also includes a buffer, which is mounted on the frame and located on the same side of the two hanging rods. The two hanging rods can drive the support plate to swing until one end of the support plate contacts the buffer.

[0017] The advantages of adopting the above-mentioned further solution are that the structure is simple and the design is reasonable. The buffer effectively cushions the support frame and slag bag during the swing process, and avoids the support frame and the slag bag on it from colliding with the frame during the swing process, which would affect the tipping of the slag bag.

[0018] Furthermore, the flipping disc includes a disc body and a hook assembly, the disc body being eccentrically mounted on the support plate; the hook assembly is mounted on the disc body for hooking the slag bag.

[0019] The beneficial effect of adopting the above-mentioned further solution is that during the operation, the slag bag is supported by the pan body, and the slag bag is hooked by the hook assembly so that when the pan body is turned over later, the slag bag can be turned over with the pan body so as to pour out the slag inside the slag bag and ensure that the slag inside the slag bag is poured out smoothly.

[0020] Furthermore, the hook assembly includes a pair of hooks that are mounted opposite each other on the disc body, and can flip over to hook onto the hanging pins that are distributed oppositely at the bottom of the slag bag when it is lowered.

[0021] The advantages of adopting the above-mentioned further solution are that the structure is simple and the design is reasonable. When the slag bag is lowered, the weight of the slag bag itself causes the pair of hooks to flip. During the flipping process, the corresponding ends of the pair of hooks hook the hanging pins that are distributed at the bottom of the slag bag to stabilize the slag bag and ensure that the slag bag flips together with the plate, thereby realizing the smooth dumping of the slag bag.

[0022] Furthermore, the hook assembly includes two pairs of hooks, which are distributed opposite each other on the disc body. When the slag bag is lowered, the hooks can be flipped to hook the two pairs of hanging pins distributed opposite each other at the bottom of the slag bag.

[0023] The advantages of adopting the above-mentioned further scheme are that the structure is simple and the design is reasonable. When the slag bag is lowered, the weight of the slag bag itself causes the pair of hooks to flip. During the flipping process, the corresponding ends of the two pairs of hooks hook the hanging pins that are distributed at the bottom of the slag bag to stabilize the slag bag and ensure that the slag bag flips together with the plate, thereby realizing the smooth dumping of the slag bag.

[0024] Furthermore, one end of each pair of hooks is rotatably connected to the disc body via a rotating shaft, and a roller is coaxially fixedly sleeved on each pair of rotating shafts.

[0025] The advantages of adopting the above-mentioned further solution are that the structure is simple and the design is reasonable. During the lowering process of the slag bag, the rollers are used to change the sliding friction between the rotating shaft and the slag bag into rolling friction, thereby reducing friction and ensuring that the hook can successfully hook the pin on the slag bag.

[0026] Furthermore, the plate hook mechanism includes a pair of plate hooks and two main winches, with the two main winches respectively mounted on the frame; the pair of plate hooks are respectively suspended on the two main winches for attaching suspension shafts that are distributed opposite to each other on the top sides of the slag bag.

[0027] The beneficial effect of adopting the above-mentioned further solution is that during the operation, the main winch drives the plate hook to move up and down, and the plate hook cooperates with a pair of suspension shafts on the slag bag to send the slag bag to the tilting plate.

[0028] Furthermore, the plate hook mechanism also includes an automatic retractor, which is mounted on the frame and connected to the pair of plate hooks to assist the pair of plate hooks in dumping the slag bag.

[0029] The advantages of adopting the above-mentioned further solution are that the structure is simple and the design is reasonable. During operation, the automatic retractor can make the pair of plate hooks hook the pair of suspension shafts during the flipping process, ensuring the stable flipping of the slag bag.

[0037] Example 1 like Figures 1 to 11 As shown, this embodiment provides an intelligent automated bag-turning gantry crane, including: a frame 1 and a bag-turning device. The bag-turning device includes a plate hook mechanism and a support and turning mechanism. The support and turning mechanism is installed at one end of the frame 1. The plate hook mechanism is installed on the frame 1 and can reciprocate along the direction from one end of the frame 1 to the other end. It is used to lift and transport slag bags 2 and send the slag bags 2 to the support and turning mechanism. At the same time, it cooperates with the support and turning mechanism to turn the slag bags 2.

[0038] During the operation, the slag bag 2 is sent to the support and flipping mechanism through the plate hook mechanism. At the same time, the plate hook mechanism works with the support and flipping mechanism to flip the slag bag 2 to complete the dumping of the slag inside the slag bag 2. The dumping is convenient, efficient, safe and reliable.

[0039] Preferably, in this embodiment, the frame 1 is a portal frame.

[0040] Preferably, in this embodiment, several traveling wheels are evenly spaced at both ends of the bottom of the frame 1, which is a reasonable design that facilitates the movement of the entire frame 1 and makes operation convenient.

[0041] Based on the above scheme, the rack 1 adopts existing technology, and its specific structure and principle will not be described in detail here.

[0042] This embodiment has a compact structure and reasonable design, which can realize the stable conveying and turning of slag bags during metallurgical operations, with high operating efficiency. The slag dumping is relatively concentrated, which facilitates subsequent centralized processing and is safe and reliable.

[0043] Example 2 Based on Embodiment 1, in this embodiment, the support and flipping mechanism includes a support frame and a flipping disc. The support frame is mounted on the frame 1 and can swing back and forth. The flipping disc is mounted on the support frame and can flip up and down to support and hook the slag bag 2.

[0044] During operation, the slag bag 2 is sent to the tilting plate by the plate hook mechanism. At the same time, the plate hook mechanism drives the slag bag 2 and the tilting plate to rotate together to complete the dumping of the slag in the slag bag 2. The dumping is convenient, efficient and safe.

[0045] The structure is compact and rationally designed, enabling stable conveying and turning of slag bags during metallurgical operations. It has high operational efficiency, and the slag dumping is relatively concentrated, facilitating subsequent centralized processing, and is safe and reliable.

[0046] Example 3 Based on Embodiment 2, in this embodiment, the support frame includes a support plate 3 and two hanging rods 4, which are arranged opposite to each other and their upper ends are rotatably connected to the frame 1 respectively; the support plate 3 is distributed between the lower ends of the two hanging rods 4, and its two ends are rotatably connected to the lower ends of the two hanging rods 4 respectively; the flip plate is installed on the support plate 3.

[0047] During operation, the slag bag 2 is delivered to the support plate 3 by the plate hook mechanism. At the same time, the plate hook mechanism drives the slag bag 2, the support plate 3 and the two hanging rods 4 to rotate together to complete the dumping of the slag in the slag bag 2. The dumping is convenient, efficient and safe.

[0048] The scheme has a simple structure. The support frame using support plate 3 and two hanging rods 4 is more reasonable. Furthermore, the support plate 3, the two hanging rods 4, and the frame 1 form a parallelogram during the tilting of the slag bag 2, ensuring the stable tilting of the slag bag 2 and making it safer and more reliable.

[0049] Preferably, in this embodiment, the support plate 3 is a rectangular plate.

[0050] In addition, the aforementioned flip plate is installed on one side of the support plate 3.

[0051] Alternatively, an opening can be made in the support plate 3 that runs vertically through it, and the flip plate can be installed in the opening.

[0052] In addition, the opening is open at one end of the support plate 3, and the top of the slag bag 2 faces the opening when it is poured out, so as to pour out the slag inside the slag bag 2.

[0053] Example 4 Based on embodiment 3, in this embodiment, the support flipping mechanism further includes a buffer 5, which is installed on the frame 1 and located on the same side of the two hanging rods 4. The two hanging rods 4 can drive the support plate 3 to swing until one end of the support plate 3 contacts the buffer 5.

[0054] During the operation, the slag bag 2 is sent to the support plate 3 through the plate hook mechanism. At the same time, the plate hook mechanism drives the slag bag 2, the support plate 3 and the two hanging rods 4 to rotate together to complete the dumping of the slag in the slag bag 2. The dumping is convenient, efficient and safe. In addition, due to the gravity of the slag bag 2, the entire support frame will move towards the frame 1 until the corresponding end of the support plate 3 contacts the buffer 5. The buffer 5 will then buffer the entire support frame to prevent the support frame from violently colliding with the frame 1.

[0055] The scheme has a simple structure and reasonable design. It uses the buffer 5 to effectively buffer the support frame and slag bag 2 during the swing process, so as to avoid the support frame and the slag bag 2 on it from colliding with the frame 1 during the swing process and affecting the tipping of the slag bag.

[0056] Based on the above scheme, the buffer 5 adopts existing technology, and its specific structure and principle will not be described in detail here.

[0057] Alternatively, a buffer spring can be used instead of the buffer 5. In this case, the buffer spring is fixedly installed on the frame 1 and extends in the horizontal direction.

[0058] Example 5 Based on any one of Embodiments 3 to 4, in this embodiment, the flipping disc includes a disc body 6 and a hook assembly. The disc body 6 is eccentrically mounted on the support plate 3. The hook assembly is mounted on the disc body 6 and is used to hook the slag bag 2.

[0059] During the operation, the slag bag 2 is sent to the support plate 3 through the plate hook mechanism. At the same time, the plate hook mechanism drives the slag bag 2, the support plate 3 and the two hanging rods 4 to rotate together to complete the dumping of the slag in the slag bag 2. The dumping is convenient, efficient and safe. In addition, due to the gravity of the slag bag 2, the entire support frame will move towards the frame 1 until the corresponding end of the support plate 3 contacts the buffer 5. The buffer 5 will then buffer the entire support frame to prevent the support frame from violently colliding with the frame 1.

[0060] Meanwhile, during the operation, the slag bag 2 is supported by the disc body 6, and the slag bag 2 is hooked by the hook assembly so that when the disc body 6 is turned over, the slag bag 2 can be turned over with the disc body 6 so as to pour out the slag inside the slag bag 2 and ensure that the slag inside the slag bag 2 is poured out smoothly.

[0061] Preferably, in this embodiment, the disk 6 is a rectangular disk, which is rotatably mounted on the support plate 3 via a pivot.

[0062] In addition, the scheme utilizes the eccentric setting of the disc 6 to ensure the rapid rotation of the disc 6 so as to pour out the slag bag 2.

[0063] Alternatively, the disk 6 mentioned above can be set without eccentricity, but in this case, the disk 6 is not as easy to flip as the eccentric setting mentioned above.

[0064] Example 6 Based on embodiment 5, in this embodiment, the hook assembly includes a pair of hooks 7, which are mounted opposite each other on the disc body 6. When the slag bag 2 is lowered, the hooks 7 can flip over and hook onto the hanging pins 8 that are distributed oppositely at the bottom of the slag bag 2.

[0065] During the operation, the slag bag 2 is sent to the support plate 3 through the plate hook mechanism. At the same time, the plate hook mechanism drives the slag bag 2, the support plate 3 and the two hanging rods 4 to rotate together to complete the dumping of the slag in the slag bag 2. The dumping is convenient, efficient and safe. In addition, due to the gravity of the slag bag 2, the entire support frame will move towards the frame 1 until the corresponding end of the support plate 3 contacts the buffer 5. The buffer 5 will then buffer the entire support frame to prevent the support frame from violently colliding with the frame 1.

[0066] Meanwhile, during the operation, the slag bag 2 is supported by the disc body 6, and the slag bag 2 is hooked by the pair of hooks 7 so that when the disc body 6 is turned over, the slag bag 2 can be turned over with the disc body 6 so as to pour out the slag inside the slag bag 2 and ensure that the slag inside the slag bag 2 is poured out smoothly.

[0067] The scheme has a simple structure and reasonable design. When the slag bag 2 is lowered, the weight of the slag bag 2 itself causes the pair of hooks 7 to flip. During the flipping process, the corresponding ends of the pair of hooks 7 hook the hanging pins 8 that are distributed at the bottom of the slag bag 2 to stabilize the slag bag 2 and ensure that the slag bag 2 flips together with the disc 6, thereby realizing the smooth dumping of the slag bag 2.

[0068] Preferably, in this embodiment, the opposite ends of the pair of hanging pins 8 are fixedly connected to the slag bag 2, and their opposite ends extend in the horizontal direction.

[0069] Example 7 Based on embodiment 5, in this embodiment, the hook assembly includes two pairs of hooks 7, which are distributed opposite to each other on the disc body 6. When the slag bag 2 is lowered, it can flip over and hook onto the two pairs of hanging pins 8 distributed opposite to each other at the bottom of the slag bag 2.

[0070] During the operation, the slag bag 2 is sent to the support plate 3 through the plate hook mechanism. At the same time, the plate hook mechanism drives the slag bag 2, the support plate 3 and the two hanging rods 4 to rotate together to complete the dumping of the slag in the slag bag 2. The dumping is convenient, efficient and safe. In addition, due to the gravity of the slag bag 2, the entire support frame will move towards the frame 1 until the corresponding end of the support plate 3 contacts the buffer 5. The buffer 5 will then buffer the entire support frame to prevent the support frame from violently colliding with the frame 1.

[0071] Meanwhile, during the operation, the slag bag 2 is supported by the disc body 6, and the slag bag 2 is hooked by the two pairs of hooks 7 so that when the disc body 6 is turned over, the slag bag 2 can be turned over with the disc body 6 so as to pour out the slag inside the slag bag 2 and ensure that the slag inside the slag bag 2 is poured out smoothly.

[0072] The scheme has a simple structure and reasonable design. When the slag bag 2 is lowered, the weight of the slag bag 2 itself causes the pair of hooks 7 to flip. During the flipping process, the corresponding ends of the two pairs of hooks 7 hook the hanging pins 8 that are distributed at the bottom of the slag bag 2 respectively, so as to stabilize the slag bag 2 and ensure that the slag bag 2 flips together with the plate 6, thereby realizing the smooth dumping of the slag bag 2.

[0073] Preferably, in this embodiment, the opposite ends of each pair of hanging pins 8 are fixedly connected to the slag bag 2, and their opposite ends extend in the horizontal direction.

[0074] The above embodiments 6 and 7 are parallel solutions. Embodiment 6 provides a single hook structure on each side of the slag bag 2, while embodiment 7 provides a double hook structure on each side of the slag bag 2. The double hook structure is preferred, as it can further ensure the stability of the slag bag 2 connection.

[0075] In addition, in both Embodiment 6 and Embodiment 7, two pairs of positioning plates 15 are provided on the disc body 6, which are used to position the slag bag 2, thereby further increasing the stability of the slag bag 2.

[0076] In addition, the inner sides of the two pairs of positioning plates 15 are respectively arc-shaped and fit against the outer wall of the slag bag 2, further ensuring the stability of the slag bag 2.

[0077] Alternatively, the two pairs of positioning plates 15 mentioned above can also be rectangular plates, but in this case, the contact area between the positioning plates 15 and the outer wall of the slag bag 2 is limited, and the stability of the slag bag 2 is not as good as the above solution.

[0078] Moreover, the two pairs of positioning plates 15 are arranged in a cross shape.

[0079] Alternatively, two pairs of positioning blocks can be used to replace the two pairs of positioning plates 15 mentioned above.

[0080] Example 8 Based on Embodiment 6 or Embodiment 7, in this embodiment, one end of each pair of hooks 7 is rotatably connected to the disc body 6 via a rotating shaft 9, and a roller 10 is coaxially fixedly sleeved on each pair of rotating shafts 9.

[0081] During the operation, the slag bag 2 is sent to the support plate 3 through the plate hook mechanism. At the same time, the plate hook mechanism drives the slag bag 2, the support plate 3 and the two hanging rods 4 to rotate together to complete the dumping of the slag in the slag bag 2. The dumping is convenient, efficient and safe. In addition, due to the gravity of the slag bag 2, the entire support frame will move towards the frame 1 until the corresponding end of the support plate 3 contacts the buffer 5. The buffer 5 will then buffer the entire support frame to prevent the support frame from violently colliding with the frame 1.

[0082] Meanwhile, during the operation, the slag bag 2 is supported by the disc body 6, and the slag bag 2 is hooked by the two pairs of hooks 7 so that when the disc body 6 is turned over, the slag bag 2 can be turned over with the disc body 6 so as to pour out the slag inside the slag bag 2 and ensure that the slag inside the slag bag 2 is poured out smoothly.

[0083] The scheme has a simple structure and reasonable design. During the lowering process, the roller 10 is used to convert the sliding friction between the rotating shaft 9 and the slag bag 2 into rolling friction, thereby reducing friction and ensuring that the hook can successfully hook the pin 8 on the slag bag 2.

[0084] Preferably, in this embodiment, one end of each rotating shaft 9 is rotatably connected to the disc body 6, and one end of the hook 7 is fixedly sleeved on the other end of the rotating shaft 9.

[0085] In addition, the roller 10 is coaxially fixed between the two ends of the rotating shaft 9.

[0086] Preferably, in this embodiment, each pair of hooks 7 can be rotatably disposed at both ends on one side of the disc body 6.

[0087] Example 9 Based on the above embodiments, in this embodiment, the plate hook mechanism includes a pair of plate hooks 11 and two main winches 12, with the two main winches 12 respectively mounted on the frame 1; the pair of plate hooks 11 are respectively suspended on the two main winches 12, and are used to attach the suspension shafts 13 that are distributed opposite to each other on the top two sides of the slag bag 2.

[0088] During the operation, two main winches 12 drive the pair of plate hooks 11 to move up and down. The pair of plate hooks 11 cooperate with a pair of suspension shafts 13 on the slag bag 2 to send the slag bag 2 to the tilting plate. At the same time, the pair of hooks 7 or two pairs of hooks 7 are used to hook the slag bag 2 so that when the plate body 6 is tilted later, the slag bag 2 can be tilted together with the plate body 6 so as to pour out the slag in the slag bag 2 and ensure that the slag in the slag bag 2 is poured out smoothly.

[0089] Preferably, in this embodiment, the pair of suspension shafts 13 are horizontally arranged, with their opposite ends fixedly connected to one opposite side of the top of the slag bag 2, and their opposite ends extending horizontally.

[0090] It should be noted that the pair of suspension shafts 13 correspond to the center of gravity of the slag bag 2, which ensures the stability of the slag bag 2 during the hooking process.

[0091] In addition, the main winch 12 mentioned above uses existing technology, and its specific structure and principle will not be described in detail here.

[0092] Example 10 Based on Embodiment 9, in this embodiment, the plate hook mechanism further includes an automatic retractor, which is installed on the frame 1 and connected to the pair of plate hooks 11 to assist the pair of plate hooks 11 in dumping the slag bag 2.

[0093] During the operation, firstly, the slag bag 2 is sent to the top of the support and tilting mechanism using the pair of plate hooks 11; then, the two main winches 12 are used to drive the pair of plate hooks 11 to move up and down respectively. The pair of plate hooks 11 cooperate with a pair of suspension shafts 13 on the slag bag 2 to send the slag bag 2 to the tilting plate. During the tilting process, the two main winches 12 slowly wind up the cables on the slag bag 2, causing it to tilt slowly. At the same time, the two auxiliary winches 14 appropriately wind up the cables on the slag bag 2 to assist the pair of hooks 11 in releasing the slag bag 2, thereby achieving a stable tilting of the slag bag 2.
