[0019] In the specific implementation process, as a preferred setting, the above-mentioned guide assembly includes a guide column 9, a slider 10 and a moving seat 11. The guide column 9 is symmetrically arranged on the side wall of the L-shaped suspension 2, the slider 10 is slidably mounted on the guide column 9, and the moving seat 11 is welded to one end of the slider 10, wherein the auxiliary limiting assembly includes a support 12, a wire drawing screw 13, a sliding seat 14, a limiting splint 15 and an elastic support member. The support 12 is symmetrically arranged on the moving seat 11, the wire drawing screw 13 is rotatably arranged on the support 12, one end of the wire drawing rod is connected to the driving member, the sliding seat 14 is symmetrically slidingly arranged on the moving seat 11 and is threadedly matched with the wire drawing screw 13 through a screw nut, the limiting splint 15 is welded to one end of the sliding seat 14, and the elastic support structure The components are arranged on the inner side of the limiting clamp 15; the above-mentioned driving component includes a servo motor 16 and a reducer 17, the servo motor 16 is arranged on one end of the moving seat 11, the input end of the reducer 17 is connected to the driving end of the servo motor 16, and the output end of the reducer 17 is connected to the drawing screw 13, wherein the moving seat 11 is symmetrically provided with guide rails 18 on both sides of the drawing screw 13, and the sliding seat 14 is provided with a slide groove, and the slide groove and the guide rail 18 are slidably matched; the above-mentioned elastic support component includes a compression spring 19, a contact plate 20 and a rubber pad 21, the compression spring 19 is arranged horizontally on the inner wall of the limiting clamp 15, the contact plate 20 is arranged on one end of the compression spring 19, and the rubber pad 21 is mounted on the side wall of the contact plate 20.

[0020] The working principle is as follows: when in use, the device is moved as a whole to the magnetic core position by the self-moving electric flat car 1, and the position of the self-moving electric flat car 1 is further adjusted so that the sling 4 at the bottom of the L-shaped suspension 2 is opposite to the magnetic core position, and the hoisting suspension mechanism 3 is controlled to move so that the sling 4 moves downward under the action of gravity. When the sling 4 moves to above the magnetic core, the magnetic core is hung in the fixed hole on the horizontal frame 6 at the bottom of the sling 4 through the lifting hook on the top of the magnetic core, and the hoisting suspension mechanism 3 is controlled to move to pull the wire rope and drive the sling 4 and the magnetic core upward. When the magnetic core moves to the position of the limit splint 15, the servo motor 16 on the moving seat 11 is started, and the driving end of the servo motor 16 rotates, which in turn drives the reducer 17 to move, thereby controlling the rotation of the drawing screw 13, and the rotation of the drawing screw 13 and then the cooperation of the screw nut Under the action, the sliding seat 14 and the limiting clamp 15 move toward each other, and then the rubber pad 21 on the side of the contact plate 20 on the limiting clamp 15 contacts the outer wall of the magnetic core. The limiting clamps 15 continue to approach each other, so that the compression spring 19 is compressed, and then under the action of the restoring elastic force of the compression spring 19, temporary limiting of the magnetic core is achieved, and the winch suspension mechanism 3 is controlled to continue to reel up, and the magnetic core is lifted to a certain height. At this time, the limiting clamp 15 on the outside of the magnetic core moves upward synchronously along the limiting guide column under the cooperation of the moving seat 11 and the slider 10. During the transportation process, the magnetic core always assists the limiting control of the limiting component, and will not shake, which can greatly improve the transportation safety. After controlling the self-moving electric flat car 1 to move to the assembly station, the limiting control of the magnetic core is released, and the magnetic core can be placed in the shell.
