Description

Technical Field

[0001] This invention relates to the field of alloy feeding equipment, specifically a wear-resistant suspended conveyor system for steelmaking alloy feeding. Background Technology

[0002] In the steelmaking process, steelmaking alloys refer to various metal or ferroalloy additives added to adjust the chemical composition of molten steel and optimize its properties, such as ferrosilicon, ferromanganese, and ferrochrome. These alloying elements play a crucial role in the strength, toughness, corrosion resistance, and microstructure of steel. The feeding device is a key hub connecting the raw material storage and the smelting furnace, safely, accurately, and timely transporting a fixed amount of alloy materials into the furnace.

[0003] In existing steelmaking alloys, during the feeding and conveying process, blocky or plate-shaped alloys collide and rub against components such as conveying troughs, pipelines, and valves, resulting in severe equipment wear and short maintenance cycles. When feeding alloy materials into high-level silos or directly into the furnace opening, the suspension and positioning of the alloy materials are inconvenient. The entire weight of the alloy materials and their supporting structures acts directly on the mechanical components, exacerbating structural fatigue and restricting the service life and operational continuity of the equipment. Summary of the Invention

[0004] The purpose of this invention is to provide a wear-resistant overhead conveying system for steelmaking alloys to solve the problem of inconvenience in using existing feeding devices.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A wear-resistant overhead conveyor system for steelmaking alloy loading includes a conveyor frame and further includes:

[0007] The suspension frame includes a sliding groove at the bottom of the conveyor frame, a sliding plate inside the sliding groove, a transmission belt between multiple sliding plates, rollers on the sliding plates, drive blocks at both ends of the transmission belt, drive wheels inside the drive blocks, a connecting frame at the bottom of the sliding plates, a suspension frame on the side wall of the connecting frame, a fixed plate between the two ends of the suspension frame, a guide rail on the fixed plate, a lifting plate slidably mounted inside the guide rail, a slider at the top of the lifting plate, a movable disc between multiple sliders, and a horizontal plate at the bottom of the guide rail with a guide groove.

[0008] The shovel plate has a movable frame that is slidably mounted on the horizontal plate. The bottom of the movable frame is equipped with a shovel plate, which is slidably mounted inside the guide groove. The top of the movable frame is provided with a transmission groove. The bottom of the lifting plate is provided with a sliding block, which is slidably mounted outside the guide rail. A transmission plate is provided on the sliding block, which slides into the transmission groove.

[0009] The feeding mechanism is connected to the movable plate and can drive the movable plate and the lifting plate to rise. The lifting plate drives the sliding block and the transmission plate to rise. The transmission plate drives multiple movable frames to move closer to each other by cooperating with the transmission groove. The shovels shovel the alloy material upward by moving closer to each other.

[0010] Based on the above technical solutions, the present invention also provides the following optional technical solutions:

[0011] In one alternative embodiment: the feeding mechanism includes a rotating rod, a top rod, and a limiting block; a fixing frame is provided inside the fixing plate; a limiting block is provided at the center of the fixing frame; a limiting groove is provided at the top of the limiting block; a rotating rod is provided inside the limiting block; and a top rod that cooperates with the limiting groove is provided outside the rotating rod.

[0012] In one alternative: a motor is installed inside the connecting frame, a drive rod is installed at the rotating end of the motor, a transmission key is installed on the outside of the rotating rod, and a keyway that cooperates with the transmission key is opened inside the drive rod.

[0013] In one alternative: a rotating tube is provided on the outside of the suspension frame, and multiple limiting teeth are provided on the outside of the rotating tube; connecting blocks are provided on both sides of the movable disc, and the connecting blocks are provided with slots that cooperate with the limiting teeth.

[0014] In one alternative: a support frame is provided on the side wall of the conveyor frame, a support frame is provided on the outside of the support frame, a base is provided at the bottom of the support frame, a guide rod and a threaded rod are provided inside the support frame, and a nut that mates with the threaded rod is provided on the support frame.

[0015] In one alternative: a drive motor is provided at the center of the base, and the rotating end of the drive motor is connected to the threaded rod.

[0016] In one alternative: both the support frame and the conveyor frame are provided with hinge blocks, each hinge block is provided with a rotating plate, the rotating plate is provided with screws, and an adjustment frame is provided between the two screws.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] The wear-resistant overhead conveyor system for steelmaking alloys transports alloy materials via a conveyor frame. As the lifting plate rises along the inclined guide rail, the inclined surface of the transmission groove on the movable frame, in conjunction with the transmission plate, converts the lifting force into a force that drives multiple shovels to retract synchronously, smoothly shoveling the material from the bottom. This reduces material spillage caused by traditional grabbing or dumping, improving the integrity and cleanliness of each material retrieval. The weight of the alloy material is borne by the conveyor frame and support frame, avoiding direct action of gravity and friction on the core drive components, ensuring stable and efficient conveying, extending the service life of the equipment, and reducing maintenance costs.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0030] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0031] like Figure 1-9 As shown, a wear-resistant overhead conveyor system for steelmaking alloy loading, provided in one embodiment of the present invention, includes a conveyor frame 1, and further includes:

[0032] The suspension frame 19 has a sliding groove 101 at its bottom, and a sliding plate 13 is installed inside the sliding groove 101. A transmission belt 17 is installed between multiple sliding plates 13, and rollers 18 are installed on the sliding plates 13. A drive block 14 is installed at both ends of the transmission belt 17, and two drive blocks 14 are connected by a connecting spring 15, so that the transmission belt 17 is always kept taut. A drive wheel 16 driven by a motor is installed inside the drive block 14. When the drive wheel 16 rotates, it can drive the transmission belt 17 and the sliding plates 13 fixed thereon to move, thereby realizing the conveying of alloy materials suspended below the sliding plates 13. A connecting frame 12 is provided at the bottom, and a suspension frame 19 is provided on the side wall of the connecting frame 12. A fixed plate 24 is provided between the two ends of the suspension frame 19. A guide rail 26 is provided on the fixed plate 24. A lifting plate 25 is slidably provided inside the guide rail 26. A slider 30 is provided at the top of the lifting plate 25. A movable plate 21 is provided between multiple sliders 30. A square groove 211 is opened on the movable plate 21. The slider 30 is slidably provided inside the square groove 211. The lifting plate 25 is fixedly provided at the bottom of the slider 30. The lifting plate 25 slides through the inclined guide rail 26. A horizontal plate 28 is provided at the bottom of the guide rail 26. A guide groove 281 is opened on the horizontal plate 28.

[0033] A shovel plate 272 is slidably mounted on the horizontal plate 28. A movable frame 27 is slidably mounted on the bottom of the movable frame 27, and the shovel plate 272 is slidably mounted inside the guide groove 281. A transmission groove 271 is formed at the top of the movable frame 27. A sliding block 29 is provided at the bottom of the lifting plate 25, and the sliding block 29 is slidably mounted outside the guide rail 26. A transmission plate 36 is mounted on the sliding block 29 and slides into the transmission groove 271. The fixed plate 24 and guide rail 26 descend to the material stacking area, and after the horizontal plate 28 contacts the working surface, the fixed plate 24 stops descending. The feeding mechanism starts and drives the movable plate 21 to rise. The movable plate 21 drives the lifting plate 25 to slide upward along the guide rail 26 through the slider 30. When the lifting plate 25 rises, it drives the sliding block 29 at its bottom end to rise synchronously with the transmission plate 36. The transmission plate 36 squeezes the movable frame 27 through the inclined surface of the transmission groove 271, forcing multiple movable frames 27 to move closer to each other along the horizontal plate 28, so that each shovel plate 272 works together to shovel up the accumulated alloy material and complete the material picking action. The accumulated alloy material is shoveled up smoothly, which effectively prevents the material from scattering and splashing, and improves the integrity and efficiency of a single material picking.

[0034] The feeding mechanism is connected to the movable plate 21 and can drive the movable plate 21 and the lifting plate 25 to rise. The lifting plate 25 drives the sliding block 29 and the transmission plate 36 to rise. The transmission plate 36 drives multiple movable frames 27 to move closer to each other by cooperating with the transmission groove 271. The shovel plate 272 shovels the alloy material upward by moving closer to each other.

[0035] like Figure 1-4 As shown in the preferred embodiment of the present invention, the feeding mechanism includes a rotating rod 23, a top rod 35, and a limiting block 34. A fixing frame 33 is provided inside the fixing plate 24, and a limiting block 34 is provided at the center of the fixing frame 33. A limiting groove 341 is provided on the top of the limiting block 34. The limiting groove 341 is an inclined groove. A rotating rod 23 is provided inside the limiting block 34, and a top rod 35 that cooperates with the limiting groove 341 is provided outside the rotating rod 23. The rotating rod 23 rotates and drives the top rod 35 to rotate. The top rod 35 rotates obliquely upward along the inclined groove 341.

[0036] like Figure 1-5 As shown, in a preferred embodiment of the present invention, a motor 20 is provided inside the connecting frame 12, a drive rod 22 is provided at the rotating end of the motor 20, a transmission key 231 is provided on the outside of the rotating rod 23, and a keyway that cooperates with the transmission key 231 is provided inside the drive rod 22. The motor 20 drives the rotating rod 23 to rotate through the cooperation of the drive rod 22 and the transmission key 231. When the rotating rod 23 rotates, the top rod 35 rotates accordingly and moves upward along the inclined surface of the limiting groove 341, thereby lifting the movable plate 21 to realize the feeding.

[0037] like Figure 1-8 As shown in the preferred embodiment of the present invention, the suspension frame 19 is provided with a rotating tube 31 on the outside, and a plurality of limiting teeth 32 are provided on the outside of the rotating tube 31. Connecting blocks 212 are provided on both sides of the movable disk 21. The connecting blocks 212 are provided with slots 213 that cooperate with the limiting teeth 32. The bottom of the limiting teeth 32 is provided with an inclined surface. When the movable disk 21 drives the connecting blocks 212 to move upward, the connecting blocks 212 can slide along the inclined surface of the limiting teeth 32, so that the limiting teeth 32 pop outward. The limiting teeth 32 rebound under the action of elastic force, preventing the rotating tube 31 and the associated movable disk 21 from resetting downward, thus ensuring the stability of the bearing position in the feeding process and subsequent processes. When resetting is required, the rotating tube 31 can be manually or driven by the drive mechanism to disengage the limiting teeth 32 from the slots 213, thereby unlocking the locking and allowing the movable disk 21 to descend and reset smoothly.

[0038] like Figure 1-2As shown, in a preferred embodiment of the present invention, a support frame 2 is provided on the side wall of the conveyor frame 1, a support frame 11 is provided on the outside of the support frame 2, a base 10 is provided at the bottom of the support frame 11, a guide rod 4 and a threaded rod 3 are provided inside the support frame 11, and a nut 9 that cooperates with the threaded rod 3 is provided on the support frame 2. When the drive motor 8 is started, it can drive the threaded rod 3 to rotate. Through the transmission of the nut 9, the support frame 2 and the entire conveyor frame 1 are driven to rise and fall vertically along the guide rod 4 to adapt to the loading and unloading requirements of different heights.

[0039] like Figure 1-2 As shown, in a preferred embodiment of the present invention, a drive motor 8 is provided at the center of the base 10, and the rotating end of the drive motor 8 is connected to the threaded rod 3.

[0040] like Figure 1 As shown, in a preferred embodiment of the present invention, both the support frame 11 and the conveyor frame 1 are provided with hinge blocks 37, the hinge blocks 37 are provided with rotating plates 5, and the rotating plates 5 are provided with screws 6. The two screws 6 are connected by a common adjusting frame 7. The two ends of the adjusting frame 7 form a helical pair with the two screws 6 respectively. By rotating the adjusting frame 7, the screw length of the two screws 6 can be changed simultaneously, which can pull the conveyor frame 1 obliquely upward to ensure the stability of the conveyor frame 1 when feeding materials.

[0041] The above embodiments of the present invention provide a wear-resistant suspended conveying system for steelmaking alloy feeding. Based on the position of the alloy material, the drive motor 8 on the base 10 is activated. The drive motor 8 drives the threaded rod 3 to rotate, and through the helical transmission with the nut 9 fixed on the support frame 2, drives the entire conveying frame 1 to rise or fall smoothly to a predetermined height. This controls the descent of the entire material handling unit (including the suspension frame 19, fixed plate 24, etc.) suspended below the sliding plate 13. The fixed plate 24 and guide rail 26 descend accordingly until the horizontal plate 28 at the bottom of the guide rail 26 contacts the ground. Then, the motor 20 inside the connecting frame 12 is activated. The motor 20, through the cooperation of the drive rod 22 and its internal keyway with the transmission key 231 on the rotating rod 23, drives the rotating rod 23 to rotate. The top rod 35 moves upward along the inclined groove while rotating, thereby lifting the upper movable part. When the movable plate 21 rises, it drives the slider 30 through its square groove 211, which in turn drives the lifting plate 25 to slide upward along the inclined guide rail 26. The lifting plate 25 drives the sliding block 29 at its bottom end to rise synchronously with the transmission plate 36. The transmission plate 36 is inserted into the transmission groove 271 of the movable frame 27, which converts the upward movement of the lifting plate 25 into a force that drives multiple movable frames 27 to slide horizontally inward along the horizontal plate 28. This causes the shovel plates 272 at the bottom of each movable frame 27 to converge towards the center synchronously under the constraint of the guide groove 281, thus concentrating the accumulated alloy material upward and effectively preventing the material from scattering. The transmission belt 17 (which is always kept taut by the connecting spring 15) drives all the sliding plates 13 and the material picking units below them to move along the sliding groove 101. The rollers 18 reduce friction and accurately transport the material to the top of the smelting furnace feeding port.

[0042] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
