The lifting mechanism in the prior art generally lifts the heavy object directly through a wire rope. Since the wire rope has a non-rigid structure, the heavy object will shake during the lifting process. If the center of gravity of the heavy object is not directly below the lifting point, the heavy object will tilt. Utility Model Content

[0007] Preferably, the lifting beam is a double main beam structure and the distance between the main beams is greater than the length and width of the cross section of the telescopic frame. A track is installed on each main beam, and the lifting trolley spans between the two tracks.

[0008] Preferably, the winch is a double-drum structure and rotates synchronously, each drum is provided with a group of steel wire ropes downward, and the two groups of steel wire ropes are respectively connected to the two sides of the connecting seat.

[0011] Preferably, a number of electromagnets are symmetrically distributed on both sides of the suspension beam, and the lower surfaces of all the electromagnets have the same height.

[0012] (III) Beneficial effects

[0013] The utility model provides an anti-tilt lifting device for an electromagnetic chuck crane, which has the following beneficial effects:

[0014] 1. The anti-tilt lifting device of the electromagnetic suction cup crane has the effect of preventing the heavy objects from shaking through the setting of the telescopic frame. The telescopic frame with good rigidity is used as a structure to limit the lateral swing of the wire rope, which can stabilize the lower end of the wire rope to prevent shaking, thereby preventing shaking when the heavy objects are lifted.

[0015] 2. The electromagnetic suction cup crane anti-tilt lifting device has the effect of preventing the heavy object from tilting through the coordinated arrangement of the telescopic frame, the connecting seat, the suspension beam and the electromagnet. Since the heavy object is connected by multiple electromagnets, it will not tilt directly even if the center of gravity is not directly below the lifting point, but a tilting torque will be generated on the lifting structure. Since the telescopic frame, the connecting seat and the suspension beam that constitute the lifting structure are all rigid structures and are not easy to bend, the heavy object can be prevented from tilting.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] See also Figures 1 to 4The utility model provides a technical solution: an anti-tilt lifting device of an electromagnetic chuck crane, comprising a lifting beam 1, legs 2 are installed below both ends of the lifting beam 1, a track 3 is installed above the lifting beam 1, a lifting trolley 4 is arranged above the track 3, the lifting trolley 4 can travel on the track 3 when working, a winch 5 is installed above the lifting trolley 4, a telescopic frame 6 is installed below the lifting trolley 4, the lifting beam 1 is a double main beam structure and the spacing between the main beams is greater than the length and width of the cross section of the telescopic frame 6, each main beam is installed with a track 3, the lifting trolley 4 spans between the two tracks 3, a connecting seat 7 is installed at the bottom of the telescopic frame 6, a wire rope 8 is arranged between the winch 5 and the connecting seat 7, the winch 5 is a double drum structure and rotates synchronously, each drum is provided with a group of wire ropes 8 downwardly, and the two groups of wire ropes 8 are divided into They are respectively connected to both sides of the connecting seat 7. When the winch 5 is working, the connecting seat 7 is lifted and lowered by winding the wire rope 8. A suspension beam 9 is installed at the bottom of the connecting seat 7, and a rotating shaft 901 is installed in the middle position above the suspension beam 9. The rotating shaft 901 is inserted into the inside of the connecting seat 7 and can rotate so that the angle of the suspension beam 9 can be changed. The suspension beam 9 is an I-shaped steel. A plum-shaped bolt 11 is installed in the groove of the I-shaped steel near the connecting seat 7. Tightening the plum-shaped bolt 11 can lock the suspension beam 9 and the connecting seat 7. An electromagnet 10 is suspended under the suspension beam 9. The telescopic frame 6 is divided into several sections and telescopes vertically downward. When the telescopic frame 6 is telescoped downward, the electromagnet 10 can contact the ground. The telescopic frame 6 has a certain strength and does not shake even if it is extended to the bottom. A number of electromagnets 10 are symmetrically distributed on both sides of the suspension beam 9, and the lower surface heights of all electromagnets 10 are the same.

[0023] When in use, first connect the suspension beam 9 of the required length under the connecting seat 7 according to the shape and size of the weight, then hang a number of electromagnets 10 under the suspension beam 9, further loosen all the plum head bolts 11 and adjust the angle of the suspension beam 9 according to the state of the weight, then tighten the plum head bolts 11 and connect the cables to all the electromagnets 10, further hoist the electromagnet 10 to a certain height through the winch 5, then move the electromagnet 10 to the top of the weight through the cooperation of the legs 2 and the lifting trolley 4, and further lower the wire rope 8 of the winch 5 to make the electromagnet The lower surface of 10 is in contact with the weight, and the electromagnet 10 is further energized to connect the electromagnet 10 and the weight through magnetic force, and the winch 5 works to lift the weight. In this process, since the lower end of the wire rope 8 is connected to the telescopic frame 6 and the telescopic frame 6 has good rigidity, even if the center of gravity of the weight is not directly below the lifting force point, the eccentric torque generated by the weight will not bend the telescopic frame 6, thereby avoiding the tilting of the weight. Similarly, since the lower end of the wire rope 8 is restricted by the telescopic frame 6, it will not shake laterally, thereby avoiding shaking when the weight is transported.

[0024] In summary, the anti-tilt lifting device of the electromagnetic suction cup crane uses a highly rigid telescopic frame 6 as a structure to limit the lateral swing of the wire rope 8, which can stabilize the lower end of the wire rope 8 to prevent shaking, thereby preventing the heavy object from shaking when it is lifted. Since the heavy object is connected by multiple electromagnets 10, even if the center of gravity is not directly below the lifting point, it will not tilt directly but will generate a tilting torque on the lifting structure. Since the telescopic frame 6, connecting seat 7 and suspension beam 9 that constitute the lifting structure are all rigid structures and are not easy to bend, the heavy object can be prevented from tilting.
