[0023] The following provides a detailed description of the embodiments of the present application through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0024] Example 1: like Figure 1 、 Figure 2 As shown, the embodiment of the present application provides a magnetic suction transport device for a pin shaft, comprising: The magnetic attraction device 100 includes an electromagnet 110 and a control switch 120, wherein the electromagnet 110 and the control switch 120 are connected by a wire; The connecting member 200 is connected to the magnetic device 100; The sling assembly 300 includes a hook 310, a chain 330, and a handle 320, wherein the handle 320 is placed between the hook 310 and the chain 330; The power failure protection device 400 includes a battery pack 410, a dual power switching module 420, an input terminal 430, an output terminal 440, and a rectifier 450; In which, the control switch 120 is installed on the connecting part 200, the dual power switching module 420 is connected to the battery pack 410, the rectifier 450 is connected between the dual power switching module 420 and the input end 430, a charger 460 is connected between the battery pack 410 and the input end 430, the dual power switching module 420 is connected to the output end 440, the output end 440 is connected to the control switch 120, and the electromagnet 110 is provided with an adsorption surface 111.

[0025] The conventional electromagnet 110 is a physical device composed of a magnetic core and a coil, which uses the magnetic effect of electric current to generate a magnetic field. Its magnetism can be controlled by turning the current on and off. When the electromagnet 110 is energized, a magnetic attraction is generated. The on and off of the electromagnet 110 is controlled by the control switch 120, which makes it easy to use. The connector 200 is installed on the electromagnet 110, and the control switch 120 is connected to the connector 200 by a threaded connection or a fastener. The connector 200 is made of sheet metal. When the magnetic device 100 is used, it is hung on the hook 310 through the connector 200. The hook 310, the handle 320, and the chain 330 are connected in sequence. The handle 320 is used for easy gripping. The chain 330 has a high structural strength and can lift heavy metal parts. The electromagnet 110 has a magnetic attraction only when it is energized. 220V AC is provided through the input terminal 430, and the 24V DC power is converted into a continuous supply to the electromagnet 110 by the rectifier 450, so that the magnetic device 100 0 maintains the magnetic attraction. When the input end 430 suddenly loses power, the dual power switching module 420 automatically switches to powering the battery pack 410 until the input end 430 is restored to mains power. The battery pack 410 uses a lithium iron phosphate battery pack 410 with a rated voltage of 24V and a rated capacity of 15AH.

[0031] Example 2: like Figure 3 As shown, an embodiment of the present application provides a magnetic suction transport device for a pin shaft. In addition to including the above-mentioned technical features, the adsorption surface 111 is planar.

[0032] When the adsorption surface 111 is flat, it is convenient to carry the metal plate, and the larger contact area between the adsorption surface 111 and the metal plate improves the magnetic attraction effect.

[0033] Example 3: like Figure 4 As shown, an embodiment of the present application provides a magnetic suction transport device for a pin shaft. In addition to the above-mentioned technical features, the suction surface 111 is further V-shaped.

[0034] When the adsorption surface 111 is V-shaped, it is convenient to carry the metal round rod shaft, and the V-shaped adsorption surface 111 can be used for rods of different specifications and sizes.

[0035] Example 4: like Figure 1 、 Figure 3 、 Figure 4 As shown, the embodiment of the present application provides a magnetic suction transport device for a pin shaft. In addition to the above technical features, the connecting member 200 further includes: The connecting parts 210 are respectively disposed on both sides of the connecting member 200 , and the connecting parts 210 are connected to the electromagnet 110 .

The connecting portion 210 facilitates welding between the connector 200 and the electromagnet 110 or installation and connection using fasteners such as bolts. The connector 200 also has a mounting hole for installing the control switch 120 and a hanging hole for hanging the hook 310.

[0037] Example 5: like Figure 1 、 Figure 5 As shown, the embodiment of the present application provides a magnetic suction transport device for a pin shaft. In addition to the above technical features, the sling assembly 300 further includes: A winding device 340 for winding up the cable chain 330; The sensing controller 500 is connected between the handle 320 and the chain 330 . The sensing controller 500 is provided with a display screen 510 for displaying the carried weight. The sensing controller 500 is provided with a first sensor 520 .

[0038] The winding device 340 mainly uses a winch to wind up the chain 330 and uses a motor to drive the winch to rotate, thereby realizing the lifting and lowering of the magnetic device 100 suspended on the lock hook. The sensing controller 500 is connected between the handle 320 and the chain 330. When the magnetic device 100 magnetically attracts metal parts and hangs them, the sensing controller 500 has a control panel for collection, analysis, and calculation. The first sensor 520 on the sensing controller 500 can detect the weight of the magnetic metal parts and display it on the display screen 510. The first sensor 520 uses a pressure sensor.

[0039] The winding device 340 is installed on the gantry or cantilever arm, and the gantry or cantilever arm has a slide rail. The winding device 340 has a slider seat or roller that is compatible with the slide rail. The movement of the winding device 340 on the slide rail can be directly pulled by the cable chain 330 or driven by a motor screw rod or other structure, which can realize the horizontal movement of the magnetic suction device 100.

[0040] Furthermore, the handle 320 includes: The shaft 600 is used to connect the hook 310 and the sensor controller 500, and the handle 320 is movably connected to the shaft 600; The movable portion 321 is disposed at one end of the handle 320 and is disposed in the sensor controller 500; The return spring 530 is placed between the movable portion 321 and the induction controller 500 , and the return spring 530 is placed on both sides of the movable portion 321 ; The second sensors 540 are disposed in the sensor controller 500 and correspond to two sides of the movable portion 321 .

[0041] The shaft 600 is installed on the induction controller 500 and is against the first sensor 520. When the shaft 600 receives a downward pulling force, it will be able to act on the first sensor 520 to realize the detection of the first sensor 520. The handle 320 is movably connected to the shaft 600, and the movable connection between the handle 320 and the induction controller 500 is realized through the movable part 321. When the handle 320 moves in the direction away from the induction controller 500, that is, moves downward, it is against the second sensor 540 corresponding to the bottom thereof through the movable part 321. The corresponding second sensor 540 detects the signal and transmits it to the induction controller 500, controls the winding device 340 to unwind the chain 330, and realizes the downward movement of the magnetic device 100. When the handle 320 moves closer to the induction controller 500, the magnetic device 100 is moved downward. When the controller 500 moves in the direction of movement, that is, when it moves upward, the movable part 321 is offset against the corresponding second sensor 540 above it, and the corresponding second sensor 540 detects the signal and transmits it to the sensing controller 500, controlling the winding device 340 to rewind the chain 330, so that the magnetic device 100 moves upward. When the user holds the handle 320, the handle 320 moves along the axis of the shaft 600, and the magnetic device 100 is adjusted to move upward or downward. When held, the upward or downward movement of the handle 320 is released, so that the movable part 321 is separated from the second sensor 540, the winding device 340 stops working, and the height position of the magnetic device 100 does not change. The second sensor 540 adopts a pressure sensor or an infrared sensor.

[0042] Example 6: The present application also provides a method for transporting a pin using a magnetic transport device, the specific steps of which include: S1, by moving the handle 320 downward relative to the shaft 600, the magnetic device 100 is controlled to move downward, the adsorption surface 111 of the magnetic device 100 is matched with the metal object to be adsorbed, and the magnetic device 100 is powered on by the control switch 120 to magnetically attract the metal object. By moving the handle 320 upward relative to the shaft 600, the magnetic device 100 is controlled to move upward to lift the metal object; S2, move the suspended metal part and the magnetic device 100 to above the placement position, move the handle 320 downward relative to the shaft 600, control the magnetic device 100 to move downward, place the metal part in the placement position, and cut off the power of the magnetic device 100 by controlling the switch 120 to separate the magnetic device 100 from the metal part.

[0043] After the metal part is magnetically attracted by the magnetic device 100, the handle 320 is moved upward to control the winding device 340 to wind up the chain 330, so that the magnetic device 100 and the metal part are moved upward and then lifted. Then, the magnetic device 100 is moved horizontally to above the placement position through a movable cantilever arm or gantry structure. Then, the handle 320 is moved downward to control the winding device 340 to unwind the chain 330, so that the magnetic device 100 and the metal part are moved downward and placed in the corresponding position. The electromagnet 110 is de-energized by the control switch 120 to release the magnetic attraction, and the metal part is separated from the electromagnet 110.
