Description

Technical Field

[0001] The utility model relates to the technical field of scrap steel processing, in particular to a steel grabbing device for scrap steel processing. Background Art

[0002] With the rapid development of various industries, the use of steel is also increasing. At the same time, the recycling of scrap steel is particularly important. In the process of scrap steel recycling, a petal-shaped grabber is usually used to grab the scrap steel, or a large electromagnet is used to attract the scrap steel. However, due to the irregular shape of the scrap steel, the stability of the scrap steel in the grabber is poor when grabbing the scrap steel.

[0003] In the prior art, Chinese Patent Publication No. CN210340052U discloses a scrap steel grabber, comprising a column, a first rotating block, a hydraulic cylinder, a second rotating block, a grab hook, an electromagnet, and a third rotating block. The column surface is welded with the first and third rotating blocks arranged in a circular array. The hydraulic cylinder is mounted inside the first rotating block via a third latch. A travel rod is movably connected to the lower end of each hydraulic cylinder. The grab hook is mounted inside the third rotating block via a first latch. The grab hook is welded to the upper surface of each second rotating block. The lower end of each travel rod is rotatably connected to the second rotating block via a second latch. An electromagnet is disposed below the column, and a spring is mounted on the upper surface of each electromagnet. By adding an electromagnet above the interior of the grab hook, the utility model improves the stability of the scrap steel gathered within the grab hook, reduces the scrap steel from falling during the grabbing process, and improves the efficiency of scrap steel grabbing.

[0004] However, when the utility model is actually used, the shapes of scrap steel vary. When the surface is too smooth, there may be fewer force points when it is grabbed by the hook, and the friction force is limited. The stability may be poor during lifting, which poses certain safety hazards. Therefore, improvement is needed. Utility Model Content
