Description

Technical Field

[0001] This application relates to the field of engineering machinery technology, specifically to an electromagnetic lifting device and lifting machinery. Background Technology

[0002] Lifting machinery refers to electromechanical equipment used for vertically lifting or vertically lifting and horizontally moving heavy objects. Commonly used lifting machinery includes bridge cranes, gantry cranes, and tower cranes. For lifting metal materials, lifting machinery equipped with electromagnetic lifting devices is widely used due to its ease of use. This type of lifting machinery includes a moving mechanism and an electromagnetic lifting device connected to the moving mechanism. The electromagnetic lifting device can lift materials by adsorption, while the moving mechanism is used for vertically lifting and horizontally moving the electromagnetic lifting device, realizing the spatial movement of the electromagnetic lifting device, and thus realizing the lifting and movement of the material.

[0003] However, different materials have different shapes, making it difficult for a single electromagnetic lifting device to be suitable for all materials. For example, an electromagnetic lifting device designed for plate-shaped materials will have insufficient contact area and thus insufficient adsorption capacity when adsorbing materials with curved surfaces, and vice versa. This necessitates the use of different electromagnetic lifting devices for different materials, resulting in higher operating costs.

[0004] Therefore, how to solve or improve the problem of high usage costs caused by the need to use different electromagnetic lifting tools for different materials in related technologies has become an important technical problem to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, this application provides an electromagnetic lifting device and lifting machinery to solve or improve the problem of high usage costs caused by the need to use different electromagnetic lifting devices for different materials.

[0006] In a first aspect, this application provides an electromagnetic lifting device, comprising:

[0007] The crossbeam is suitable for connection with the moving mechanism;

[0008] The hoisting structure is connected to the crossbeam;

[0009] At least two first electromagnets, each having a first lifting surface for matching with the material, the first lifting surfaces of each first electromagnet being different, and each first electromagnet being detachably connected to the lifting structure.

[0010] Optionally, the at least two first electromagnets include:

[0011] A first arc-shaped electromagnet, wherein the first lifting surface of the first arc-shaped electromagnet is an arc surface, and the arc surface is adapted to match materials having an arc-shaped surface.

[0012] Optionally, the at least two first electromagnets include:

[0013] A first planar electromagnet, wherein the first lifting surface of the first planar electromagnet is a plane, and the plane is adapted to match a strip-shaped material.

[0014] Optionally, at least two hoisting structures are provided along the length of the crossbeam, and each hoisting structure can be detachably connected to one of the first electromagnets.

[0015] Optionally, it also includes:

[0016] The second electromagnet is adapted to be detachably connected to at least two of the lifting structures, respectively.

[0017] Optionally, the hoisting structure includes at least two hoisting components, each hoisting component is connected to the crossbeam, and each hoisting component is arranged sequentially along the width direction of the crossbeam. The first electromagnet can be connected to each hoisting component respectively.

[0018] Optionally, the hoisting assembly includes at least two hoisting seats, and the first electromagnet can be detachably connected to each of the hoisting seats via slings, with the at least two slings arranged at an angle to each other.

[0019] Optionally, it also includes:

[0020] Multiple hooks are provided on the crossbeam and are adapted to hang heavy objects.

[0021] Optionally, it also includes:

[0022] An electrical control system is mounted on the crossbeam and is adapted to energize the first electromagnet.

[0023] A generator is mounted on the crossbeam and is energized and connected to the electronic control system. The generator is adapted to supply power to the electronic control system.

[0024] Secondly, this application also provides a lifting machine, including a moving mechanism and any of the electromagnetic lifting devices described above, wherein the crossbeam is connected to the moving mechanism, and the moving mechanism is adapted to drive the crossbeam to move in space.

[0025] This application provides an electromagnetic lifting device, including a crossbeam, a lifting structure, and at least two first electromagnets. The crossbeam is adapted to be connected to a moving mechanism. The lifting structure is connected to the crossbeam. Each first electromagnet has a first lifting surface for matching with the material; the first lifting surfaces of each first electromagnet are different, and each first electromagnet can be detachably connected to the lifting structure.

[0026] When using an electromagnetic lifting device, the crossbeam is mounted on a moving mechanism. A first electromagnet is detachably connected to the lifting structure. The moving mechanism drives the crossbeam to move, causing the first lifting surface of the first electromagnet connected to the lifting structure to make contact with the material. When the first electromagnet is energized, it attracts the material, and the moving mechanism then drives the crossbeam to move, thus lifting the material.

[0027] When other materials need to be hoisted, the first electromagnet connected to the hoisting structure is detached, and another first electromagnet is detachably connected to the hoisting structure. The moving mechanism drives the crossbeam to move, so that the first hoisting surface of the first electromagnet connected to the hoisting structure comes into contact with the material at this time. At this time, the first electromagnet connected to the hoisting structure is energized, and the first electromagnet can attract the material. Then, the moving mechanism drives the crossbeam to move, and the material can be hoisted.

[0028] With this setup, different first electromagnets can be connected to the crossbeam depending on the material, so that one electromagnetic lifting device can lift different materials without the need to use different electromagnetic lifting devices, thus reducing the cost of use.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] The following is combined Figures 1 to 11 This describes an embodiment of the present application.

[0045] According to embodiments of this application, in one aspect, an electromagnetic lifting device is provided, such as... Figures 1 to 8As shown, the device includes a crossbeam 1, a lifting structure, and at least two first electromagnets. The crossbeam 1 can be mounted on a moving mechanism, allowing the moving mechanism to drive the crossbeam 1 to move arbitrarily in space. The lifting structure is connected to the crossbeam 1, and the first electromagnets can be detachably connected to the lifting structure, thereby connecting to the crossbeam 1 through the lifting structure.

[0046] At least two first electromagnets are provided, each having a first lifting surface for hoisting metal materials. After the metal material comes into contact with the first lifting surface, energizing the first electromagnet will attract the metal material to the first lifting surface of the first electromagnet.

[0047] The first lifting surfaces of each first electromagnet are different, that is, the first lifting surfaces of each first electromagnet are not the same.

[0048] When using electromagnetic lifting tools, the crossbeam 1 of the electromagnetic lifting tool is mounted on the moving mechanism, such as... Figures 3 to 5 As shown, a first electromagnet is detachably connected to the lifting structure. The moving mechanism drives the crossbeam 1 to move, so that the first lifting surface of the first electromagnet connected to the lifting structure comes into contact with the material. At this time, the first electromagnet connected to the lifting structure is energized, and the first electromagnet can attract the material. Then, the moving mechanism drives the crossbeam 1 to move, and the material can be lifted.

[0049] When it is necessary to lift other materials, the first electromagnet connected to the lifting structure can be removed, such as... Figures 6 to 8 As shown, another first electromagnet is detachably connected to the lifting structure. The moving mechanism drives the crossbeam 1 to move, so that the first lifting surface of the first electromagnet connected to the lifting structure comes into contact with the material at this time. At this time, the first electromagnet connected to the lifting structure is energized, and the first electromagnet can attract the material at this time. Then, the moving mechanism drives the crossbeam 1 to move, and the material can be lifted.

[0050] With this setup, different first electromagnets can be connected to the crossbeam 1 depending on the material, so that one electromagnetic lifting device can lift different materials without the need to use different electromagnetic lifting devices, thus reducing the cost of use.

[0051] As an optional embodiment, such as Figures 6 to 8 As shown, at least two first electromagnets include a first arc-shaped electromagnet 2. The first lifting surface of the first arc-shaped electromagnet 2 is an arc surface 21. This arc surface 21 can be matched with materials having arc surfaces. The materials having arc surfaces can be steel coils, steel balls, etc.

[0052] Taking a steel coil as an example, when a steel coil needs to be hoisted, it is placed horizontally. The first arc-shaped electromagnet 2 is detachably connected to the hoisting structure. The moving mechanism drives the crossbeam 1 to move, so that the arc surface 21 on the first arc-shaped electromagnet 2 matches and contacts the arc surface of the side wall of the steel coil. At this time, the first arc-shaped electromagnet 2 is energized, and the first arc-shaped electromagnet 2 can attract the steel coil. Then, the moving mechanism drives the crossbeam 1 to move, and the steel coil can be hoisted.

[0053] Since the first lifting surface of the first arc-shaped electromagnet 2 is an arc surface 21, and can match and contact the arc surface of the side wall of the steel coil, the contact area between the first lifting surface of the first arc-shaped electromagnet 2 and the steel coil is larger, thereby making the adsorption connection between the steel coil and the first arc-shaped electromagnet 2 more stable.

[0054] As an optional embodiment, such as Figures 3 to 5 As shown, at least two first electromagnets include a first planar electromagnet 3, wherein the first lifting surface of the first planar electromagnet 3 is a plane 31. This plane 31 can be matched with a strip-shaped material. The strip-shaped material can be a steel plate or steel bar, etc.

[0055] Taking a steel plate as an example, when a steel plate needs to be hoisted, the steel plate is placed flat. The first planar electromagnet 3 is detachably connected to the hoisting structure. The moving mechanism drives the crossbeam 1 to move, so that the plane 31 on the first planar electromagnet 3 matches and contacts the surface of the steel plate. At this time, the first planar electromagnet 3 is energized, and the first planar electromagnet 3 can attract the steel plate. Then, the moving mechanism drives the crossbeam 1 to move, and the steel plate can be hoisted.

[0056] Since the first lifting surface of the first planar electromagnet 3 is a plane 31, and it can match and contact the surface of the steel plate, the contact area between the first lifting surface of the first planar electromagnet 3 and the steel plate is larger, thereby making the adsorption connection between the steel plate and the first planar electromagnet 3 more stable.

[0057] In the combined embodiment, when it is necessary to hoist a steel coil, the first arc-shaped electromagnet 2 is detachably connected to the hoisting structure. When it is necessary to hoist a steel plate, the first arc-shaped electromagnet 2 is detached, and then the first planar electromagnet 3 is detachably connected to the hoisting structure.

[0058] As an optional embodiment, such as Figure 1 As shown, at least two lifting structures are provided, with each structure arranged sequentially along the length of the crossbeam 1. Each lifting structure can be detachably connected to a first electromagnet, thereby enabling the installation of a larger number of first electromagnets and increasing work efficiency.

[0059] Specifically, each hoisting structure can be connected to either the same first electromagnet or different first electromagnets.

[0060] Taking two hoisting structures as an example, the first arc-shaped electromagnet 2 can be connected to one hoisting structure, and the first planar electromagnet 3 can be connected to the other hoisting structure. Alternatively, the first arc-shaped electromagnet 2 can be connected to both hoisting structures, or the first planar electromagnet 3 can be connected to both.

[0061] With each lifting structure connected to a first planar electromagnet 3, during the lifting of the steel plate, the first lifting surface of each first planar electromagnet 3 can be matched and contacted with the surface of the steel plate. Then, each first planar electromagnet 3 is energized, causing each first planar electromagnet 3 to simultaneously attract the steel plate, resulting in a greater attraction force and preventing the steel plate from falling during the lifting process.

[0062] In optional embodiments, such as Figures 9 to 11 As shown, the electromagnetic lifting device also includes a second electromagnet 5. The second electromagnet 5 can be detachably connected to at least two lifting structures, respectively.

[0063] With this configuration, the second electromagnet 5 is connected between the two lifting structures, thus enabling it to attract the space below the two lifting structures. Compared to connecting a first electromagnet to each lifting structure, this provides a larger attraction area.

[0064] Specifically, when hoisting steel slag or scrap steel, if each hoisting structure is connected to a first electromagnet for adsorption and hoisting, each first electromagnet can only adsorb steel slag or scrap steel in the space below its own hoisting structure. Steel slag or scrap steel in the space between two hoisting structures cannot be adsorbed, thus requiring the horizontal beam 1 to be moved multiple times for adsorption and hoisting.

[0065] If the second electromagnet 5 is connected between the two lifting structures, the second electromagnet 5 can not only attract steel slag or scrap steel in the space below each lifting structure, but also attract steel slag or scrap steel in the space between the two lifting structures. The attraction area is larger, which can reduce the number of lifting operations and improve the work efficiency when lifting steel slag or scrap steel.

[0066] In some embodiments, the second electromagnet 5 can be connected to two lifting structures located on the front and rear sides of the crossbeam 1 along its length. These two lifting structures are located on the front and rear sides of the crossbeam 1 along its length, specifically the two lifting structures closest to both ends of the crossbeam 1.

[0067] With this configuration, the second electromagnet 5 is connected between the two furthest hoisting structures, resulting in a larger adsorption area.

[0068] It is worth noting that when the second electromagnet 5 is connected to the two hoisting structures located on the front and rear sides of the crossbeam 1 along its length, the second electromagnet 5 can also be connected to another hoisting structure to increase the installation stability of the second electromagnet 5.

[0069] As an optional embodiment, such as Figure 4 , Figure 7 and Figure 10 As shown, the hoisting structure includes at least two hoisting components, each connected to a crossbeam 1, and arranged sequentially along the width of the crossbeam 1. A first electromagnet can be connected to each hoisting component, making the connection of the first electromagnet more stable.

[0070] In optional embodiments, such as Figure 1 As shown, the hoisting assembly includes at least two hoisting seats 4, each hoisting seat 4 is connected to the crossbeam 1, and a sling 7 is connected to the first electromagnet. The number of slings 7 is the same as the number of hoisting seats 4, and the slings 7 can be detachably connected to the hoisting seats 4 one by one.

[0071] When the first electromagnet is connected to each of the lifting seats 4 via the slings 7, at least two slings 7 are inclined to each other, so that the two slings 7 and the crossbeam 1 form a triangular or trapezoidal structure, making the whole structure more stable.

[0072] Specifically, such as Figure 4 and Figure 7 As shown, the first electromagnet is equipped with at least two hanging rings 6, the number of which corresponds to the number of lifting components. One end of the sling 7 is attached to the hanging ring 6. The lifting base 4 has a hanging hole 41, and the end of the sling 7 away from the hanging ring 6 is attached to the hanging hole 41 and secured with a pin, thereby detachably connecting the first electromagnet to the lifting base 4. When disassembling the first electromagnet, after removing the pin, the end of the sling 7 away from the hanging ring 6 can be removed from the hanging hole 41.

[0073] For the connection between the second electromagnet 5 and the hoisting structure, a hanging ring 6 is provided on the second electromagnet 5, so that the hanging ring 6 can be detachably connected to the hanging hole 41 on the hoisting seat 4 of the hoisting component of the hoisting structure through the sling 7.

[0074] As an optional implementation method, such as Figure 1 and Figure 2 As shown, the electromagnetic lifting device also includes multiple hooks 8, each hook 8 is set on the side wall of the crossbeam 1, and heavy objects can be hung on the hooks 8. The moving mechanism drives the crossbeam 1 to move in space to realize the lifting of heavy objects.

[0075] As an optional implementation method, such as Figure 1 , Figure 3 , Figure 6 and Figure 9As shown, the electromagnetic lifting device also includes an electrical control system 9 and a generator 10. The electrical control system 9 is installed on the crossbeam 1. When the first electromagnet or the second electromagnet 5 is connected to the crossbeam 1, the first electromagnet or the second electromagnet 5 can be electrically connected to the electrical control system 9, and the electrical control system 9 can be used to energize the first electromagnet or the second electromagnet 5.

[0076] The generator 10 is mounted on the crossbeam 1. The electronic control system 9 has a battery, and the generator 10 is electrically connected to the electronic control system 9, so that the generator 10 generates electricity to supply power to the electronic control system 9.

[0077] The electronic control system 9 may have a battery, and the generator 10 is connected to the battery of the electronic control system 9 so that after the generator 10 generates electricity, it can not only directly supply power to the electronic control system 9, but also charge the battery of the electronic control system 9.

[0078] According to an embodiment of this application, another aspect provides a lifting machine, including a moving mechanism and any of the above-mentioned electromagnetic lifting devices. A crossbeam 1 is connected to the moving mechanism, which enables the crossbeam 1 to move spatially. The technical effects of this lifting machine are the same as those of the electromagnetic lifting device, and therefore will not be described further.

[0079] Although embodiments of this application have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of this application, and such modifications and variations all fall within the scope defined by this application.
