Description

Technical Field

[0001] The utility model relates to the technical field of coil material transportation devices, and more specifically, to a coil material hoisting and transportation sling. Background Art

[0002] Coil is a continuous strip tightly wound into a cylindrical shape, which is the abbreviation of steel rolled into a tube. During the transportation process, coils usually need to be hoisted at high altitudes. During hoisting and transportation, the main hoisting device used is the C-type hook. During hoisting, the coil is subjected to force on one side, which is easy to cause eccentric loading, causing the coil to slip, thereby causing safety accidents and affecting the normal progress of the hoisting work.

[0003] For example, the coil material hoist disclosed in the authorization announcement number CN 209352430 U has a hoisting rod installed on a cross bar through two vertical rods, and the coil material is hoisted on the hoisting rod. This device applies force to the left and right sides of the coil material at the same time through the two vertical rods, making the coil material more stable during the hoisting process and avoiding the situation where the coil material slips due to unbalanced loading, thereby ensuring the efficient and stable hoisting operation and improving the safety of use.

[0004] In the above, when the sling is in use, the entire sling rod needs to be removed, and then the coil is hoisted on the sling rod, and then both ends of the sling rod are installed on the vertical pole, and the sling rod and the vertical pole are locked and fixed. The whole process is relatively time-consuming and affects work efficiency. Utility Model Content

[0023] The coil material lifting and transportation sling comprises a main body 1, the main body 1 comprises an upper frame 2 and a lower frame 3 hingedly connected to the upper frame 2, a placement space for placing the coil material 4 is formed between the lower frame 3 and the upper frame 2, the upper frame 2 and the lower frame 3 are composed of a plurality of rod bodies 14, the rod bodies 14 are all cylindrical, and a rubber sheet is adhered to the outer peripheral wall of the rod body 14 to avoid scratching the inner wall of the coil material 4, which would result in poor use effect.

[0024] The side wall of the lower frame 3 is rotatably connected with a connecting rod 5, which includes a rod body 14 and a sphere 15. The sphere 15 and the rod body 14 are integrally formed. A connecting hole 6 is opened on the connecting rod 5, and the connecting hole 6 includes a connecting section 16 and a rotating section 17. The connecting section 16 is adapted to the rod body 14, and the rotating section 17 is spherical. The sphere 15 is placed in the rotating section 17, and the sphere 15 can rotate in the rotating section 17. By inserting the sphere 15 into the rotating section 17, the rotation between the connecting rod 5 and the lower frame 3 is realized, and the connection between the upper frame 2 and the lower frame 3 is realized through the connecting rod 5.

[0025] A docking groove 7 is provided in the upper frame 2, and a docking hole 8 is provided on the side wall of the upper frame 2. The docking hole 8 is connected to the docking groove 7. A locking assembly is provided in the docking groove 7. The locking assembly includes a strong permanent magnet 9, a spring 10, an iron ring 11, two steel balls 12 and a steel nail 13.
