Description

Technical Field

[0001] This utility model relates to the field of metallurgical equipment technology, specifically to an electromagnetic hoist for charging in front of a furnace. Background Technology

[0002] In the metallurgical production process, furnace charging is a crucial step. Currently, the commonly used furnace charging hoisting equipment is mostly traditional mechanical hook cranes or ordinary electromagnetic cranes. Traditional mechanical hook cranes require manual hooking and unhooking operations when lifting metal materials, which is not only inefficient but also poses significant safety hazards, especially in harsh furnace environments with high temperatures and dust, where the personal safety of operators cannot be effectively guaranteed. While ordinary electromagnetic cranes can use electromagnetic force to attract metal materials, eliminating the manual hooking step, they suffer from poor attraction stability. During lifting, materials are prone to falling due to electromagnetic force fluctuations and vibrations, causing material loss and equipment damage. In addition, existing furnace-front feeding and lifting equipment is insufficient in terms of the accuracy of material positioning and delivery, making it difficult to meet the demands of modern metallurgical production for efficient and precise feeding. Therefore, an electromagnetic crane for furnace-front feeding is proposed. Utility Model Content

[0003] This utility model provides an electromagnetic hoist for loading materials in front of a furnace. It has the advantages that during the hoisting process, the operator can adjust the posture of the material as needed to ensure the stability of the material during the hoisting process, and effectively prevent the material from falling.

[0004] This utility model provides the following technical solution: an electromagnetic hoist for charging in front of a furnace, including a base plate, with locking sections welded to the top of each base plate, a support crossbar fixedly connected to one side of the outer wall of each of the locking sections, and a sliding groove opened at the top of each of the two support crossbars, with rollers slidably connected to the outer wall of each of the two sliding grooves, and an equipment box fixedly connected to one side of the outer wall of each of the two rollers. A controller is installed at the top of the equipment box, and a drive motor is installed on one side of the inner bottom surface of the equipment box. The output end of the drive motor passes through a limit seat, a transmission wheel set and a transmission wheel in sequence via a transmission rod. A rotating frame is connected to the side of the transmission wheel set away from the drive motor. A constraint seat is connected to the bottom end of the rotating frame via a steel wire rope. A lifting head is connected to the bottom end of the constraint seat.

[0005] As a preferred embodiment of this utility model, a rotating joint is rotatably connected to the bottom of the inner wall of the lifting head, a connecting seat is fixedly connected to the bottom of the inner wall of the rotating joint, and a support base is bolted to the bottom of the connecting seat.

[0006] As a preferred embodiment of this utility model, a bottom mounting base is welded to the bottom end of the support base, and an electromagnetic suction block is provided at the bottom end of the bottom mounting base.

[0007] As a preferred embodiment of this utility model, the top two sides of the electromagnetic suction block are each fitted with a connecting frame, and the ends of the two connecting frames away from the electromagnetic suction block are fitted with the outer wall of the connecting seat.

[0008] As a preferred embodiment of this utility model, a clamping rod is movably connected to one side of the outer wall of the transmission wheel, and a base is fixedly connected to the bottom end of the clamping rod.

[0011] Compared with the prior art, this utility model provides an electromagnetic hoist for charging in front of the furnace, which has the following beneficial effects: 1. This furnace-front charging system uses an electromagnetic crane. A controller energizes the electromagnetic chuck, generating a strong electromagnetic force that attracts magnetically conductive metal materials. Simultaneously, the controller starts the drive motor, which, via a transmission rod, sequentially rotates the limit seat, transmission wheel assembly, and transmission wheel. The rotation of the transmission wheel, through a wire rope, drives the rotating frame. This rotation raises the constraint seat and the lifting head, lifting the electromagnetic chuck with the material. During lifting, the rotating section allows the lifting head to move freely, enabling operators to adjust the material's posture as needed, ensuring stability during transport. 2. The electromagnetic hoist used for feeding the furnace is configured to control the hydraulic pump through a controller. The hydraulic pump drives the linkage rod through the hydraulic system, which in turn drives the clamping rod to clamp the transmission wheel, ensuring that the material is firmly secured and stopped during hoisting. Even if there are fluctuations in the electromagnetic force or equipment vibration, it can effectively prevent the material from falling. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1-4 This utility model discloses an electromagnetic hoist for charging in front of a furnace, including a base plate 1, with locking sections 2 welded to the top of the base plate 1, and a support crossbar 3 fixedly connected to one side of the outer wall of multiple locking sections 2. The top of each of the two support crossbars 3 is provided with a sliding groove 4, and rollers 5 are slidably connected to the outer wall of the two sliding grooves 4. An equipment box 6 is fixedly connected to one side of the outer wall of the two rollers 5. A controller 7 is installed at the top of the equipment box 6, and a drive motor 8 is installed on one side of the inner bottom surface of the equipment box 6. The output end of the drive motor 8 passes through the limit seat 9, the transmission wheel set 26 and the transmission wheel 10 in sequence via a transmission rod. The side of the transmission wheel set 26 away from the drive motor 8 is connected to a rotating frame 15. The bottom end of the rotating frame 15 is connected to a constraint seat 16 via a steel wire rope. The bottom end of the constraint seat 16 is connected to a lifting head 17.

[0016] Specifically, the base plate 1 serves as the basic support component of the electromagnetic crane, capable of withstanding various loads during equipment operation. The locking joint 2 is welded to the top of the base plate 1 and connects to the support crossbar 3, ensuring the support crossbar 3 is stably fixed to the base plate 1 and providing support for the movement and guidance of the entire equipment. The support crossbar 3 is fixedly connected to one side of the outer wall of the locking joint 2, and its top opening has a groove 4 providing a sliding track for the roller 5. The roller 5 is slidably connected to the groove 4. The equipment box 6 is fixedly connected to one side of the outer wall of the roller 5. When the electromagnetic crane needs to move, the roller 5 rolls within the groove 4, driving the equipment box 6 and the entire hoisting actuator to move along the direction of the support crossbar 3. The electromagnetic crane can move flexibly in the horizontal direction, facilitating material loading operations at different positions in front of the furnace. The drive motor 8 is located on one side of the bottom end face inside the equipment box 6, serving as a power source. It transmits power sequentially to the limit seat 9, the transmission wheel set 26, and the transmission wheel 10 through the transmission rod. The transmission wheel set 26 and the transmission wheel 10 are mounted on the transmission rod. The transmission wheel set 26 consists of two transmission wheels, enabling speed change and power transmission. The transmission wheel 10 rotates under the drive of the transmission rod. Through cooperation with the clamping rod 11 and the linkage rod 12, the transmission wheel 10 is clamped to ensure that the material does not sway when it is lifted to the designated position. The transmission wheel 10 transmits power to the rotating frame 15, which rotates under the drive of the transmission wheel set 26. It is connected to the constraint seat 16 via a wire rope, thereby driving the lifting head 17 to achieve lifting and lowering motion, completing the material lifting operation. One end of the rotating frame 15 is rotatably connected to the fixed seat 23 on one side of the inner wall of the equipment box 6, and the other end is connected to the constraint seat 16 via a wire rope. The rotating frame 15 rotates under the drive of the transmission wheel set 26. By winding and unwinding the wire rope, the constraint seat 16 and the lifting head 17 are lifted and lowered. The constraint seat 16 is used to fix and guide the wire rope to ensure the stability of the lifting head 17 during the lifting process. The lifting head 17 is the part that directly contacts the material. The rotating joint 18 is rotatably connected to the bottom of its inner wall, which allows the lifting head 17 to rotate flexibly during the lifting process, making it convenient to adjust the posture of the material and achieve precise delivery.

[0017] In this embodiment, a rotating joint 18 is rotatably connected to the bottom of the inner wall of the lifting head 17, a connecting seat 19 is fixedly connected to the bottom of the inner wall of the rotating joint 18, and a support base 20 is bolted to the bottom of the connecting seat 19.

[0018] Specifically, the rotating section 18 is fixedly connected to the bottom of the inner wall of the connecting seat 19, and the connecting seat 19 is bolted to the top of the support base 20. The setting of the rotating section 18 gives the lifting head 17 the function of rotation, and the support base 20 provides an installation support platform for components such as the electromagnetic suction block 25. Its structural design ensures the stability and reliability of the entire lifting actuator.

[0019] In this embodiment, a bottom mounting base 21 is welded to the bottom end of the support base 20, and an electromagnetic suction block 25 is provided at the bottom end of the bottom mounting base 21.

[0020] Specifically, the bottom mounting base 21 is welded to the bottom of the support base 20 and is used to install the electromagnetic suction block 25. The electromagnetic suction block 25 is the core component for material adsorption. It generates a strong electromagnetic force by energizing the material, thus adsorbing magnetically conductive metallic materials. In this embodiment, the top two sides of the electromagnetic suction block 25 are each attached to a connecting frame 22, and the ends of the two connecting frames 22 away from the electromagnetic suction block 25 are attached to the outer wall of the connecting seat 19.

[0021] Specifically, the connecting brackets 22 on both sides of the top of the electromagnetic chuck 25 are snapped onto the outer wall of the connecting seat 19 to ensure that the connection between the electromagnetic chuck 25 and the lifting head 17 is firm and will not fall off during the lifting process.

[0022] In this embodiment, a clamping rod 11 is movably connected to one side of the outer wall of the transmission wheel 10, and a base 14 is fixedly connected to the bottom end of the clamping rod 11. A linkage rod 12 is movably connected to the other side of the outer wall of the transmission wheel 10, and the linkage rod 12 and the clamping rod 11 are slidably connected through a shaft.

[0023] Specifically, a clamping rod 11 is movably connected to one side of the outer wall of the transmission wheel 10, and a linkage rod 12 is movably connected to the other side. The linkage rod 12 and the clamping rod 11 are slidably connected through a shaft. When the transmission wheel 10 rotates, it drives the clamping rod 11 and the linkage rod 12 to move. Under the drive of the hydraulic pump 13, the clamping rod 11 can clamp the transmission wheel 10, further enhancing the stability of the material during the lifting process and preventing the material from falling due to electromagnetic force fluctuations or other reasons.

[0024] In this embodiment, a hydraulic pump 13 is fixedly connected to the end of the linkage rod 12 away from the clamping rod 11, and the hydraulic pump 13 is fixedly connected to one side of the top of the base 14.

[0025] Specifically, the hydraulic pump 13 provides power for the clamping action of the clamping rod 11. The clamping force of the clamping rod 11 is controlled by the hydraulic system and can be flexibly adjusted according to the weight and shape of the material to ensure the reliability of the clamping effect.

[0026] In this embodiment, a fixed seat 23 is rotatably connected to one end of the rotating frame 15. The fixed seat 23 is located on one side of the inner wall of the equipment box 6, and a pressure plate 24 is fixedly connected to one side of the top of the fixed seat 23. The pressure plate 24 is located at the top of the constraint seat 16.

[0027] Specifically, by setting the pressure plate 24, the external wire rope will not be misaligned during transmission.

[0028] The working principle and usage process of this utility model are as follows: When the electromagnetic crane needs to be moved to a designated position in front of the furnace for material loading, the operator issues a movement command through the controller 7. Upon receiving the command, the controller 7 controls the drive motor 8 to start. The drive motor 8 drives the roller 5 to roll within the groove 4 of the support crossbar 3 via the transmission rod. The rolling of the roller 5 causes the equipment box 6 and the entire hoisting actuator to move along the direction of the support crossbar 3. After the electromagnetic crane reaches the loading position, the controller 7 controls the electromagnetic suction block 25 to be energized. The electromagnetic suction block 25 generates a strong electromagnetic force, attracting the magnetically conductive metal material. Simultaneously, the controller 7 controls the drive motor 8 to start. The drive motor 8 drives the limit seat 9, the transmission wheel group 26, and the transmission wheel 10 to rotate sequentially via the transmission rod. After the transmission wheel 10 rotates, it drives the rotating frame 15 via the wire rope. The rotation of the rotating frame 15 causes the constraint seat 16 and the lifting head 17 to rise, lifting the electromagnetic suction block 25 with the adsorbed material. During the lifting process, the rotating joint 18 allows the lifting head 17 to rotate flexibly. The operator can adjust the posture of the material as needed to ensure the stability of the material during the lifting process. To further improve the safety of the material lifting process and prevent the material from falling, after the material is lifted, the controller 7 controls the hydraulic pump 13 to work. The hydraulic pump 13 pushes the linkage rod 12 through the hydraulic system. The linkage rod 12 drives the clamping rod 11 to move, so that the clamping rod 11 clamps the transmission wheel 10. The magnitude of the clamping force can be precisely adjusted by the controller 7 according to the weight and shape of the material to ensure that the material is firmly clamped during the lifting process. Even if there are fluctuations in the electromagnetic force or equipment vibration, it can effectively prevent the material from falling.
