[0002] With the development of science and technology, electromagnetism has gradually been used in engineering projects. One of the tools used to lift large metal objects such as steel plates, beams, and frames is the electromagnetic lifter. The electromagnetic lifter is a device that uses electromagnetism to lift objects. The electromagnetic lifter is mainly used in industries such as transportation to lift magnetic materials such as steel. The electromagnetic lifter mainly includes a lifting chain and an electromagnetic suction cup. The electromagnetic suction cup is installed at the bottom of the connecting mechanism, which is connected to the lifting equipment and lifted by the lifting equipment. The electromagnetic suction cup absorbs magnetic materials such as steel. When absorbing magnetic materials, the lifting equipment lowers the electromagnetic suction cup, and the electromagnetic suction cup falls on the magnetic material for absorption.

[0003] The existing bridge-type electromagnetic crane usually controls the lifting and lowering of the workpiece by setting a lifting chain. However, it has certain limitations when placing the workpiece because the movement of the lifting chain makes it inconvenient to control the placement direction of the workpiece. At the same time, when the workpiece is placed by the lifting chain, the lifting chain will shake, which will cause the workpiece to shake, and is not stable enough. Utility Model Content

[0022] The utility model is further described in detail below:

[0023] like Figures 1 to 5 As shown, the utility model provides a bridge type electromagnetic crane, including a bridge frame 1 and an end beam 2 arranged on the bridge frame 1, a main beam 3 is movably installed on the top of the end beam 2, a running trolley 4 is movably installed on the top of the main beam 3, the running trolley 4 includes a trolley body 41, a mounting plate 42 is fixedly connected to the side of the trolley body 41, a reduction box 44 is fixedly installed on the top of the mounting plate 42, a servo motor 43 is fixedly installed on the top of the reduction box 44, a rotating drum 45 is movably installed on the bottom of the trolley body 41, a gear ring 46 is fixedly installed on the outside of the rotating drum 45, a driving gear 47 meshing with the gear ring 46 is fixedly installed on the outside of the output shaft of the reduction box 44, a stabilizing component 6 is movably installed on the bottom of the rotating drum 45, and an electromagnetic hanger 7 is fixedly installed on the bottom of the stabilizing component 6.

[0024] By turning on the power, the electromagnetic hanger 7 is used to adsorb the workpiece, and the servo motor 43 cooperates with the reduction box 44 to drive the driving gear 47 located below the mounting plate 42 to rotate. The driving gear 47 is engaged with the gear ring 46 to drive the rotating drum 45 installed below the trolley body 41 to rotate, so as to facilitate the flexible adjustment of the direction angle of the workpiece movement and improve the flexibility. At the same time, through the stabilizing component 6 arranged under the running trolley 4, the scissor arm 64 can be folded between the upper connecting frame 61 and the lower connecting frame 62, so that the electromagnetic hanger 7 on the stabilizing component 6 is driven to rise and fall through the hook to avoid shaking when the workpiece moves, and the stability of the electromagnetic hanger 7 fixing the workpiece is guaranteed by the stabilizing component 6.

[0025] like Figure 4 and Figure 5 As shown, the stabilizing assembly 6 includes an upper connecting frame 61 and a lower connecting frame 62, a slide rail 63 is fixedly installed on the inner side of the upper connecting frame 61 and the lower connecting frame 62, a scissor arm 64 is movably installed between the upper connecting frame 61 and the lower connecting frame 62, and one side of the scissor arm 64 is slidably connected to the inside of the slide rail 63.

[0026] The scissor arms 64 are folded and slid along the slide rails 63 to make the lower connecting frame 62 move downward along with the electromagnetic hanger 7 and away from the upper connecting frame 61. After the electromagnetic hanger 7 contacts the workpiece and controls it to be adsorbed on the outside of the workpiece, the lifting and lowering motor 48 is controlled to retract the lifting chain and pull the lower connecting frame 62 through the lifting ring 65 to drive the electromagnetic hanger 7 to move upward, so that the scissor arms 64 are folded to lift and move the workpiece, thereby the scissor arms 64 are located in the upper connecting frame 61 and the lower connecting frame 62 and are folded and retracted to ensure the stability of the electromagnetic hanger 7.

[0027] like Figure 2 As shown, a lifting motor 48 and a mounting frame 49 are fixedly installed on the top of the trolley body 41, and a lifting chain is movably installed on the inner side of the mounting frame 49.

[0028] like Figure 4 As shown, a lifting ring 65 is provided on the top of the lower connecting frame 62 .

[0029] The hook on the lifting chain is mounted by setting the lifting ring 65, and the lifting chain is set in the mounting frame 49 to cooperate with the stabilizing component 6 to control the lifting of the electromagnetic hanger 7 to lift the workpiece.

[0030] like Figure 3 As shown, the driving gear 47 is disposed below the mounting plate 42 .

[0031] The driving gear 47 is arranged below the mounting plate 42 , and is driven by the servo motor 43 to rotate, thereby driving the gear ring 46 meshing therewith to rotate. The rotation of the gear ring 46 drives the rotating drum 45 to rotate, thereby adjusting the orientation angle of the workpiece.

[0032] like Figure 3 As shown, the interior of the drum 45 is hollow.

[0033] The hollow configuration of the rotating drum 45 reduces the weight and facilitates the passage of the hanging chain.

[0034] like Figure 4 As shown, the upper connecting frame 61 is connected to the rotating drum 45 by bolts.

[0035] The upper connecting frame 61 is connected to the rotating drum 45 by bolts, so that it can be disassembled, thereby improving flexibility.

[0036] like Figure 1 and Figure 2 As shown, a trolley traveling mechanism 5 is fixedly installed on the outside of the main beam 3 , and a trolley traveling mechanism 410 is fixedly installed on the outside of the trolley body 41 .

[0037] The main beam 3 can be driven to move along the end beam 2 by the trolley traveling mechanism 5 , and the trolley body 41 can be driven to move along the main beam 3 by the trolley traveling mechanism 410 .

[0038] The following is a detailed description of the working principle of the bridge type electromagnetic crane.

[0039] like Figures 1 to 5 As shown, the main beam 3 is controlled to move along the end beam 2 and the trolley body 41 is controlled to move along the main beam 3 to adjust the position by the trolley walking mechanism 5 and the trolley walking mechanism 410 respectively. The electromagnetic hanger 7 is moved above the workpiece, and the lifting and lowering motor 48 is controlled to release the lifting chain mounted on the lifting ring 65 to lower the electromagnetic hanger 7. The scissor arm 64 slides and folds along the slide rail 63 to make the lower connecting frame 62 move downward with the electromagnetic hanger 7 away from the upper connecting frame 61. After the electromagnetic hanger 7 contacts the workpiece and controls the adsorption outside the workpiece, the lifting and lowering motor 48 is controlled to retract the lifting chain and pull the lower connecting frame through the lifting ring 65. The frame 62 drives the electromagnetic hanger 7 to move upward so that the scissor arm 64 is folded to lift and move the workpiece. The servo motor 43 is controlled to reduce speed and increase torque through the reduction box 44 to drive the driving gear 47 located below the mounting plate 42 to rotate. Since the driving gear 47 is meshed with the gear ring 46, the rotating drum 45 is rotated and connected to the bottom of the trolley body 41. The driving gear 47 drives the gear ring 46 to rotate and drives the rotating drum 45 to rotate at the same time. The rotation of the rotating drum 45 drives the stabilizing component 6 and the electromagnetic hanger 7 below to rotate, and then drives the workpiece adsorbed under the electromagnetic hanger 7 to rotate, adjust the angle and place it.

[0040] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
