Description

Technical Field

[0001] The utility model relates to the technical field of cranes, in particular to an electromagnetic hanging beam sling. Background Art

[0002] An electromagnetic hanging beam crane is a device that uses electromagnetic magnets to attract magnetic weights to achieve the lifting of magnetic weights. Existing electromagnetic hanging beam slings generally include a crossbeam connected to a corresponding steel wire rope, with at least two electromagnetic magnets fixedly installed at intervals at the bottom of the crossbeam. For example, Chinese patent publication number CN218088528U discloses a rotatable electromagnetic hanging beam sling. However, this electromagnetic hanging beam sling is only suitable for magnetic weights with flat top surfaces, such as steel plates and wage steel. Existing Chinese patent application publication number CN104495634A discloses an electromagnetic hanging beam sling, in which the top of the electromagnetic magnet is connected to the bottom of the crossbeam by four chains. Although this electromagnetic hanging beam sling can meet the lifting operations of magnetic weights with non-horizontal top surfaces, it is only suitable for magnetic weights with a small angle of inclination on the top surface. It is still unable to adapt to the lifting operations of magnetic weights with uneven top surfaces or protruding structures.

[0003] For this purpose, we designed an electromagnetic hanging beam hanger. Utility Model Content

[0004] In order to overcome the deficiencies in the background technology, the utility model discloses an electromagnetic hanging beam hanger.

[0005] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical solutions:

[0006] An electromagnetic hanging beam hanger includes a hanging beam, two electromagnetic suction cups are symmetrically arranged at the bottom of the hanging beam, the electromagnetic suction cup includes a fixed plate, a linear slide groove is provided on the lower plate surface of the fixed plate, the linear slide groove is slidably connected to an electromagnetic adsorption component extending from the bottom, and a side spring is provided between the electromagnetic adsorption component and the corresponding linear slide groove end face.

[0007] Preferably, the linear slide is slidably connected to two electromagnetic adsorption members that are spaced apart, and an intermediate spring is provided between the two electromagnetic adsorption members.

[0008] Preferably, the lower disk surface of the fixed disk is provided with a plurality of linear slide grooves distributed in an array.

[0009] Preferably, the electromagnetic chuck is slidably connected to the bottom of the hanging beam along the length direction of the hanging beam.

[0010] Preferably, the bottom of the hanging beam is rotatably connected to a bidirectional lead screw arranged along its length direction, and the two lead screw parts of the bidirectional lead screw are connected to the electromagnetic chuck in a one-to-one correspondence;

[0011] At least one end of the bidirectional lead screw is provided with a driving member capable of driving the lead screw to rotate.

[0012] Preferably, the length direction of the linear slide is perpendicular to the moving direction of the electromagnetic chuck.

[0013] Preferably, arc structures are provided on both sides of the bottom of the electromagnetic adsorption component corresponding to its moving direction.

[0014] Preferably, the linear slide is T-shaped, and rolling wheels are provided on both sides of the top of the electromagnetic adsorption component corresponding to the sides perpendicular to the moving direction thereof.

[0015] Due to the adoption of the above-mentioned technical solution, the utility model has the following beneficial effects:

[0016] 1. When there is a groove or protrusion on the top surface of the workpiece corresponding to the magnetic adsorption part, which cannot fit with the bottom surface of the magnetic adsorption part, the electromagnetic adsorption part can be moved to avoid the above structure, so that the bottom surface of the electromagnetic adsorption part can completely fit the top surface of the workpiece, thereby realizing the function of increasing the adaptability to different workpieces;

[0017] 2. The setting of the arc structure can adaptively adjust the position of the electromagnetic adsorption component when the convex structure on the top surface of the workpiece conflicts with the arc structure, so that the bottom surface of the electromagnetic adsorption component can completely fit the top surface of the workpiece;

[0018] 3. The electromagnetic suction cup is slidably connected to the hanging beam, and can drive the bidirectional screw to move through the driving member, thereby moving the electromagnetic suction cup. The overall movement of the electromagnetic suction cup avoids the structure of the protrusion or groove on the top surface of the workpiece that the electromagnetic adsorption part cannot avoid when moving alone, ensuring that the bottom surface of the electromagnetic adsorption part can completely fit the top surface of the workpiece.
