Description

Technical Field

[0001] This utility model relates to the field of electromagnetic lifting device technology, specifically a multifunctional, fully covered electromagnetic lifting device. Background Technology

[0002] Electromagnetic lifting devices are lifting tools that use electromagnetic coils to generate a magnetic field to attract heavy objects. They require an external power supply, and the magnetic force changes with the on / off state of the current. They are suitable for magnetic materials such as steel and are widely used in industries such as metallurgy and machining. Electromagnetic lifting devices are an important type of magnetic lifting device. Their magnetic force is generated by energizing the electromagnetic coil, and they mainly rely on the power supply of the electromagnetic coil to generate the magnetic field.

[0003] In existing electromagnetic lifting devices, all electromagnets are located at the same height and cannot be adjusted. This means that the higher parts of the steel plate can be attracted by the corresponding electromagnets, while the lower parts cannot. This results in poor attraction and the steel plate is prone to falling during lifting. Since the higher parts of the steel plate are already attracted by the electromagnets, the corresponding electromagnets need to descend a certain distance after contacting the steel plate, causing the electromagnets to press the steel plate downwards, which can easily cause the steel plate to bend or be damaged.

[0004] To overcome the above-mentioned defects, the prior art (Chinese Patent No. CN113548571B, Publication Date: 2024-01-30) discloses an electromagnetic lifting device, a crane, and a pallet. The electromagnetic lifting device includes a control unit, a beam structure, and multiple first electromagnet structures. Each first electromagnet structure is connected to a first sliding member. The first sliding member is connected to a first guide member that can slide along the first sliding member. The first sliding member is fixedly connected to a first limiting member for blocking the corresponding first guide member. The first limiting member is located on the side of the first guide member away from the first electromagnet structure. The first guide member is fixedly connected to the beam structure. The height direction of the first electromagnet structure and the sliding direction of the first guide member are both located in the height direction of the electromagnetic lifting device. The electromagnetic lifting device also includes a second electromagnet structure and a detection unit for a first signal. The output end of the detection unit and the control end of the lifting mechanism are electrically connected to the control unit. This electromagnetic lifting device can use the first electromagnet structure to adsorb steel plates and the second electromagnet structure to adsorb pallets, thereby lifting and transporting the cut parts and pallets as a whole.

[0005] While the above design can solve the aforementioned problems, it cannot transfer the cut materials as a whole. The materials need to be sorted on the material table of the unloading equipment, which occupies the unloading equipment for a long time, resulting in a decrease in the utilization rate of the unloading equipment. Furthermore, it cannot adjust the electromagnetic adsorption force according to different thicknesses of the sheet metal, which can easily damage the cutting table grid. At the same time, the lack of flexible connection between the electromagnet and the hanging beam makes it difficult to adapt to the deformation of the steel plate after cutting. Utility Model Content

[0006] The purpose of this utility model is to provide a multifunctional, fully covered electromagnetic lifting device to solve the problems mentioned in the background art, such as the inability to transfer the cut materials as a whole, the need to sort the materials on the material table of the unloading equipment, the long-term occupation of the unloading equipment, the resulting decrease in the utilization rate of the unloading equipment, the inability to adjust the electromagnetic adsorption force according to the different thicknesses of the plate, the easy damage to the cutting table grid, and the lack of flexible connection between the electromagnet and the lifting beam, making it difficult to adapt to the deformation of the cut steel plate.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional full-coverage electromagnetic lifting device, comprising a lifting beam structure body, an extension support plate installed below the lifting beam structure body, and a flexible buffer mechanism for adjusting the electromagnetic adsorption module installed inside the extension support plate, the flexible buffer mechanism comprising a sliding nested rod, the sliding nested rod being nested and connected inside the extension support plate, an extension integral plate installed on the outer surface of the extension support plate, and an engagement adjustment mechanism for moving the extension support plate installed above the extension integral plate.

[0008] Furthermore, the meshing adjustment mechanism includes a rotary drive motor, which is fixedly installed on the left and right sides of the main body of the hanging beam structure. The outer surface of the output end of the rotary drive motor is equipped with a reverse threaded rod, and the thread of the reverse threaded rod is designed to be symmetrical and reversed.

[0009] Furthermore, multiple sets of docking adjustment blocks are symmetrically installed on the outer surface of the reversing threaded rod, and the internal contact surface of the docking adjustment block is a correspondingly designed threaded hole. Transmission connecting rods are installed on the left and right sides of the docking adjustment block, and the top of the extended integral plate is rotatably installed at the end of the transmission connecting rod.

[0010] Furthermore, a compression spring is installed on the outer surface of the extended support plate, and the lower end of the compression spring abuts against the upper surface of the extended support plate. The electromagnetic adsorption module is rotatably installed at the end of the sliding nested rod, and the electromagnetic adsorption module is an electromagnetically symmetrical design with left and right rotation installation.

[0011] Furthermore, inclined connecting rods are installed on the left and right sides of the main body of the hanging beam structure, and a central rotating block is installed on the top of the two sets of inclined connecting rods. The outer surface of the inclined connecting rod is provided with a mating groove, and a nested sliding block is installed inside the mating groove.

[0012] Furthermore, a shrink-fitting rod is installed on the outer surface of the electromagnetic adsorption module, and a compression buffer spring is installed on the outer surface of the shrink-fitting rod. The other end of the inclined connecting rod is slidably installed on the outer surface of the shrink-fitting rod, and the sliding trajectory of the inclined connecting rod abuts against the corresponding two ends of the compression buffer spring.

[0013] Furthermore, an adjustable support frame is installed on the lower surface of the main body of the lifting beam structure, and multiple sets of extended support plates are slidably installed inside the adjustable support frame. The inner surface of the adjustable support frame contacts the outer surface of the extended support plate to form a sliding structure, and the outer surface of the reverse threaded rod contacts the inner surface of the mating adjustment block to form an engaging structure.

[0014] Compared with the prior art, the beneficial effects of this utility model are: When the electromagnetic adsorption module performs adsorption operation, the electromagnetic adsorption module will rotate to squeeze the inclined connecting rod and the central rotating block inward. At this time, the elastic effect of the compression buffer spring will ensure the flexibility and stability of the electromagnetic adsorption module through the inclined connecting rod. This design allows the equipment to transfer the cut material as a whole without occupying the electromagnet of the unloading equipment. In addition, the flexible connection between the lifting beams can quickly adapt to the deformation of the cut steel plate.

[0015] Furthermore, when it is necessary to perform adsorption operations on steel plates of different lengths, the rotary drive motor is directly started to adjust the extension support plate laterally through the reverse threaded rod and the docking adjustment block, so that multiple sets of extension support plates can be quickly adjusted in length. This design improves the material utilization rate of the equipment and can adjust the electromagnetic adsorption force according to the different thicknesses of the plates without damaging the cutting table grid.

[0016] Furthermore, the main body of the lifting beam structure and the adjusting support frame are designed as a single unit, with the extended support plate sliding along the inside of the adjusting support frame to fit and limit movement. This design makes the equipment more stable and efficient to use. Attached Figure Description

[0024] 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.

[0025] Example 1: Please refer to Figure 2 , Figure 3 and Figure 4 This utility model provides the following technical solution: a multifunctional, fully covered electromagnetic lifting device, including a lifting beam structure body 1, an extended support plate 3 installed below the lifting beam structure body 1, and a flexible buffer mechanism for adjusting the electromagnetic adsorption module 6 installed inside the extended support plate 3, the flexible buffer mechanism including a sliding nested rod 4, such as... Figure 3 As shown, the sliding nested rod 4 is nested and installed inside the extension support plate 3, and the outer surface of the extension support plate 3 is equipped with an extension integral plate 17, and an engagement adjustment mechanism for moving the extension support plate 3 is installed above the extension integral plate 17.

[0026] like Figure 2 , Figure 3 and Figure 4 The technical solution shown, in order to solve the problem of the lack of flexible connection between the electromagnet and the lifting beam, making it difficult to adapt to the deformation of the cut steel plate and thus unable to transfer the cut material as a whole, requiring material sorting on the material unloading equipment platform, which occupies the unloading equipment for a long time and leads to a decrease in the utilization rate of the unloading equipment, discloses the following: a compression spring 5 is installed on the outer surface of the extension support plate 3, and the lower end of the compression spring 5 abuts against the upper surface of the extension support plate 3; an electromagnetic adsorption module 6 is rotatably installed at the end of the sliding nested rod 4, and the electromagnetic adsorption module 6 is an electromagnetically symmetrical design with left and right rotation installation; and inclined connecting rods 7 are installed on the left and right sides of the main body 1 of the lifting beam structure, such as... Figure 4As shown, the tops of the two sets of inclined connecting rods 7 are respectively equipped with a central rotating block 8. The outer surface of the inclined connecting rod 7 is provided with a mating groove 12, and a nested sliding block 11 is installed inside the mating groove 12. The outer surface of the electromagnetic adsorption module 6 is equipped with a shrinking fitting rod 9, and the outer surface of the shrinking fitting rod 9 is equipped with a compression buffer spring 10. The other end of the inclined connecting rod 7 is slidably installed on the outer surface of the shrinking fitting rod 9, and the sliding trajectory of the inclined connecting rod 7 abuts against the corresponding two ends of the compression buffer spring 10.

[0027] When the electromagnetic adsorption module 6 is needed to adsorb and transfer the steel plate, the main body 1 of the lifting beam structure and the adjusting support frame 2 are directly activated to drive the extension support plate 3 to the position of the steel plate until the electromagnetic adsorption module 6 contacts the steel plate. Since the electromagnetic adsorption module 6 is a symmetrically rotated electromagnetic adsorption block, it will automatically rotate and adjust according to the shape of the steel plate after contacting it. As the electromagnetic adsorption module 6 rotates, the inclined connecting rods 7 fixed on the left and right sides of the outer surface will be adjusted laterally in sync. The movement of the two sets of inclined connecting rods 7 will synchronously drive the rotating block 8 at its connecting end. Furthermore, the movement of the inclined connecting rods 7 will slide laterally stably against the outer surface of the shrinking fitting rod 9. Figure 4 As shown, the inner groove 12 of the inclined connecting rod 7 on the outer surface of the connecting rod 7 will fit against the outer surface of the shrinking fitting rod 9. At the same time, the movement of the inclined connecting rod 7 will drive the nested sliding block 11 that is slidably installed inside the connecting rod 9 in sync. During the movement of the nested sliding block 11, its other end will fit against the outside of the shrinking fitting rod 9 for limiting sliding. The inward sliding of the left and right nested sliding blocks 11 will correspondingly squeeze the two ends of the compression buffer spring 10 that is slidably installed outside the shrinking fitting rod 9. The elasticity of the compression buffer spring 10 will adjust the position of the steel plate by the corresponding adsorption through the electromagnetic adsorption module 6. This design makes the use of the equipment more stable.

[0028] Example 2: Figure 1 , Figure 5 and Figure 6 The technical solution shown, in order to solve the problem of the inability to adjust the electromagnetic adsorption force according to different thicknesses of the sheet material, which easily damages the cutting table grid, discloses the following: The meshing adjustment mechanism includes a rotary drive motor 13, which is fixedly installed in two groups on the left and right sides of the main body 1 of the lifting beam structure. A reverse threaded rod 14 is installed on the outer surface of the output end of the rotary drive motor 13, and the thread design of the reverse threaded rod 14 is symmetrical and reversed. Multiple sets of mating adjustment blocks 15 are symmetrically installed on the outer surface of the reverse threaded rod 14, such as... Figure 5As shown, the internal contact surface of the docking adjustment block 15 is a correspondingly designed threaded hole. The left and right sides of the docking adjustment block 15 are equipped with transmission connecting rods 16, and the top of the extended integral plate 17 is rotatably installed at the end of the transmission connecting rod 16. The lower surface of the main body 1 of the hanging beam structure is equipped with an adjustment support frame 2, and the extended support plate 3 is slidably installed in multiple groups inside the adjustment support frame 2. The inner surface of the adjustment support frame 2 contacts the outer surface of the extended support plate 3 to form a sliding structure, and the outer surface of the reverse threaded rod 14 contacts the inner surface of the docking adjustment block 15 to form a meshing structure.

[0029] When adjustments to the equipment are required based on the thickness and area of ​​the steel plate, the rotary drive motors 13 fixedly installed on both sides of the main body 1 of the lifting beam structure are directly started to rotate. The operation of the rotary drive motors 13 synchronously drives the reverse threaded rods 14 fixedly installed on the outer surface of the output end. During the rotation of the reverse threaded rods 14, the externally nested adjusting blocks 15 are synchronously driven. Since the interior of the adjusting blocks 15 has correspondingly designed threaded hollow holes, the reverse threaded rods 14 are adjusted by meshing with the adjusting blocks 15 during rotation, resulting in lateral limiting movement. Because the reverse threaded rods 14 are designed with multiple symmetrically installed threaded rods, the adjusting blocks 15, also with multiple meshing designs, will synchronously move inward in two corresponding groups. Figure 6 As shown, during the inward movement of the docking adjustment block 15, the transmission connecting rods 16, which are rotatably mounted on the left and right sides, will be driven synchronously, so that the transmission connecting rods 16 will pull the extended integrated plate 17, which is also rotatably mounted on the other end, accordingly. Since the extended integrated plate 17 is fixedly mounted on the side of the extended support plate 3, the extended support plate 3 will change its position inward as the reverse threaded rod 14 rotates continuously. Furthermore, the movement of the extended support plate 3 will proceed along the interior of the adjustment support frame 2, which is fixedly mounted on the lower surface of the main body 1 of the hanging beam structure, thereby achieving a fixing effect for steel plates of different thicknesses and lengths.
