Description

Technical Field

[0001] The utility model relates to the technical field of hoisting, in particular to a permanent magnetic hoist. Background Art

[0002] Permanent magnetic lifters mostly use high-performance rare earth permanent magnets (NdFeB) as the magnetic source, which have the characteristics of no power consumption, strong suction, low residual magnetism, easy operation, long life, safety and reliability.

[0003] However, the permanent magnetic lifting devices commonly found on the market can generally only be used to move steel plates, blocks and cylindrical magnetic conductive materials. For the lifting of angle steel, round steel and I-beam, it is often necessary to first tie the angle steel with a lifting rope and then hang the lifting rope on the hook. This requires turning around and threading the rope, which is cumbersome and dangerous. The electromagnetic lifting device has a heavy weight, a high risk of power failure and low reliability.

[0004] In view of the above-mentioned existing permanent magnetic lifters, the operation is cumbersome when lifting angle steel, round steel, I-beam and other objects, and the electromagnetic lifters are heavy and prone to power failure causing the objects to fall. A permanent magnetic lifter is needed to solve the above problems. Summary of the invention

[0005] The utility model proposes a permanent magnetic lifter to solve the problem that the current permanent magnetic lifter is cumbersome to operate when lifting angle steel, round steel, I-beam and other objects, and the electromagnetic lifter is heavy and prone to power failure causing the objects to fall.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is a permanent magnetic lifter, including a fixed plate, lifting ears are fixed at both ends of the top of the fixed plate, a permanent magnetic disk is arranged under the fixed plate, the permanent magnetic disk and the fixed plate are connected by a connecting plate, and a safety anti-drop assembly is installed on the connecting plate. When in use, the crane wire rope is connected through the lifting ears, and then the lifting steel is magnetically adsorbed by the permanent magnetic disk, so that the lifting steel can be lifted, and the lifting steel is further protected by the safety anti-drop assembly to prevent the lifting steel from falling after the permanent magnetic disk suddenly loses magnetism. The overall structure of the lifter is simple and practical.

[0007] Furthermore, the safety anti-slip assembly includes two anti-slip grabs, which are respectively arranged on both sides of the permanent magnetic disk, and the two anti-slip grabs are rotatably connected to the connecting plate. The two anti-slip grabs are rotatably connected to the connecting rods, and the hinge point between the anti-slip grabs and the connecting rods is located outside the hinge point between the anti-slip grabs and the connecting plate. A connecting block is provided in the middle of the fixed plate, and a grab lifting ring is fixed on the top of the connecting block. The two connecting rods are rotatably connected to the connecting block. The grab lifting ring is lifted upward by a steel wire rope, and then the connecting block is lifted. The two connecting rods are lifted upward by the connecting block, and the two anti-slip grabs are lifted by the connecting rods. The opening and closing of the anti-slip grabs can be controlled, and the hoisted steel magnetically adsorbed at the bottom of the permanent magnetic disk can be covered by the two anti-slip grabs to prevent the hoisted steel from suddenly falling.

[0008] Furthermore, the middle portion of the fixing plate is hollow, and the connecting block is movably arranged in the hollow portion of the fixing plate.

[0009] Furthermore, two connecting plates are provided, the two connecting plates are fixed to the bottom of the fixing plate, and the connecting plates and the lifting lugs are arranged in a cross shape.

[0010] Furthermore, the anti-slip grab is located between the two connecting plates.

[0011] Furthermore, the two anti-slip grab buckets are arranged symmetrically.

[0012] The beneficial effects of the utility model are:

[0013] The sling is provided with a safety anti-drop component so as to support the suspended object in the event of a power failure, thereby preventing the suspended object from directly falling. The sling has good use effect and strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS
