Description

Technical Field

[0001] This utility model belongs to the field of lifting equipment, specifically, it relates to a chain-type electromagnetic crane lifting device for lifting ferromagnetic materials. Background Technology

[0002] With the rapid development of industry, electromagnetic cranes are widely used in many sectors such as steel production, processing, and logistics transportation. The main component of an electromagnetic crane's lifting device is the electromagnet. When current is applied, the electromagnet attracts steel items, lifting them to the designated location. When the current is cut off, the magnetism disappears, and the steel items are lowered. However, current electromagnetic cranes have certain limitations in their design. Existing technology uses a simple disk structure as the lifting device. While this disk structure can attract steel and other items using electromagnetic principles, its stability during handling, especially when the crane is moving or turning, is poor. Irregularly shaped items are also prone to detaching from the disk during lifting, significantly increasing the risk factor of the entire operation. Utility Model Content

[0003] To address the technical problems encountered during the handling process of electromagnetic crane lifting devices, especially when the crane is moving or turning, where the adhesion stability is poor and irregularly shaped items are easily detached from the disk during lifting, significantly increasing the risk factor of the entire operation, the basic concept of the technical solution adopted by this utility model is as follows:

[0004] A chain-type electromagnetic crane lifting device for lifting ferromagnetic materials includes an electromagnetic control box. The top of the electromagnetic control box is provided with a first lifting lug, and the bottom of the electromagnetic control box is provided with a second lifting lug. The first lifting lug is connected to one end of a zipper, and the other end of the zipper is connected to a lifting interface. The second lifting lug is connected to a rigid chain, which is composed of rings connected in series.

[0005] In a preferred embodiment of this utility model, the electromagnetic control box is provided with a wiring port.

[0006] In a preferred embodiment of this utility model, the bottom of the electromagnetic control box is provided with two or more lifting lugs, and a rigid chain is connected to the lifting lugs. Two or more rigid chains are arranged around the center of the bottom of the electromagnetic control box.

[0007] In a preferred embodiment of this utility model, the zipper is connected to the lifting lug and the lifting interface to form a stable lifting structure.

[0008] In a preferred embodiment of this utility model, the rigid chain is made of high-strength magnetic material, and the rigid chain can be arranged in parallel or in a cross arrangement.

[0009] Compared with the prior art, the present invention has the following advantages:

[0010] Compared to traditional disk structures, this utility model employs multiple rigid chains connected to an electromagnetic control box. This multi-contact adsorption method significantly enhances the stability of the adsorption process. Furthermore, when lifting objects of different shapes and sizes, the rigid chains can be adjusted to maintain a tight fit with the object's surface, achieving stable adsorption. This high flexibility in lifting greatly expands its application range. By connecting the power supply to the electromagnetic control box, magnetism is generated. Connecting to a power source alters the magnetic force, allowing for the lifting of different types of workpieces. Operation is convenient and reduces the risk of errors.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0017] like Figures 1 to 2 As shown, a chain-type electromagnetic crane lifting device for lifting ferromagnetic materials includes an electromagnetic control box 1. The top of the electromagnetic control box 1 is provided with a lifting lug 5, and the bottom of the electromagnetic control box 1 is provided with a lifting lug 7. The lifting lug 5 is connected to one end of a zipper 4, and the other end of the zipper 4 is connected to a lifting interface 3. The lifting lug 7 is connected to a rigid chain 2, which is composed of rings 8 connected in series.

[0018] In the setup, the lifting interface 3 is connected to the electromagnetic control box 1 via the lifting lug 5, and the lifting interface 3 is connected to the crane boom. When the crane moves and turns, the stability is good. During lifting, the length of the rigid chain 2 can be adjusted by the number of rings 8 connected in series. At the same time, the rigid chain 2 can be flexibly arranged. When handing over items, the arrangement can be parallel or cross, which increases the stability and adsorption force when in contact with the items, greatly expanding its application range.

[0019] like Figures 1 to 2 As shown in the figure, in a specific embodiment, the electromagnetic control box 1 is provided with a wiring port 6.

[0020] In the setup, the connection port 6 can be connected to an external power source. When the power source is connected to the electromagnetic coil in the electromagnetic control box 1, the electromagnetic control box 1 generates a magnetic force. The rigid chain 2, due to the electromagnetic induction generated by the electromagnetic control box 1, generates magnetism and can firmly attract objects. Depending on the material, weight, and shape of the workpiece, the electromagnetic control box 1 can change the current by connecting to the power source, thereby changing the magnetic strength generated by the rigid chain 2. This maintains a stable attraction force throughout the handling process, effectively avoiding the risk of items falling off and improving the safety and reliability of lifting operations.

[0021] like Figures 1 to 2 As shown, in a specific embodiment, the bottom of the electromagnetic control box 1 is provided with two or more lifting lugs 7, and a rigid chain 2 is connected to the lifting lugs 7. Two or more rigid chains 2 are arranged around the center of the bottom of the electromagnetic control box 1.

[0022] In the setup, the rigid chain 2 is connected by the second lifting lug 7, which increases the number of contact points between the rigid chain 2 and the electromagnetic control box 1, greatly enhancing the stability of the adsorption when suspending objects of different shapes and sizes.

[0023] like Figures 1 to 2 As shown, in a specific embodiment, the zipper 4 is connected to the lifting lug 5 and the lifting interface 3 to form a stable lifting structure.

[0024] In this setup, the hoisted item is lifted by connecting to the crane boom via the designated lifting interface 3.

[0025] like Figures 1 to 2As shown in the specific embodiment, the rigid chain 2 is made of high-strength magnetic material. The chain can generate sufficient magnetism under the action of an electromagnetic field to ensure the safety of lifting. The rigid chain 2 can be arranged in parallel or cross arrangement. The rigid chain 2 is connected in series by the ring 8. It can be seen that the rigid chain 2 has a flexible arrangement when handing over items. The cross arrangement of the chain can provide a more uniform magnetic force distribution, thereby effectively preventing the object from slipping or tilting during the lifting process. The lifting flexibility is high, which increases the stability and adsorption force of contact with the object.

[0026] When using this equipment, in the unpowered state, connect the connector 3 to the crane boom and control the rigid chain 2 to contact the surface of the object being transported. The operator can adjust the position of the rigid chain 2 according to the actual shape and surface condition of the object to ensure that the rigid chain 2 can fully contact all parts of the object. At this time, the power supply can be connected through the connector 6. Under the action of current, the surface of the rigid chain 2 quickly generates a strong magnetism, attracting the suspended item. The strength of the magnetism can be adjusted by the power supply to ensure a firm and reliable attraction. During the movement, the connecting structure, the connector 3, the zipper 4, and the lifting lug 5 remain stable. Whether moving in a straight line or turning, due to the multi-contact adsorption characteristics of the rigid chain 2, it will not fall off due to the shaking or changes in the movement of the crane. When it is necessary to lower the object, the operator only needs to cut off the power. With the interruption of the current, the magnetism on the surface of the rigid chain 2 quickly disappears. At this time, the attraction between the workpiece and the rigid chain 2 also disappears, and the workpiece can be lifted off the rigid chain 2, completing the entire lifting and transport process.
