Internal hanging type hoisting tool for hoisting conveying of coiled strip steel

Abstract

An internal hanging type hoisting tool for hoisting conveying of coiled strip steel comprises two steel hoisting rods which are connected together through an upper end transverse connecting rod. Internal hanging blocks protruding outwards are transversely arranged at the lower ends of the hoisting rods respectively, connecting blocks expending obliquely upwards and outwards are arranged at the upper ends of the hoisting rods respectively, two lantern rings are connected to the outer ends of the connecting blocks in a hung mode through hanging connection holes respectively, and a hanging chain ring for hanging a hoisting conveying hook is connected between the two lantern rings in a sleeved mode. The cross section of each hoisting rod is a big-end-up cuboid. The upper end face of each internal hanging block is a plane perpendicular to the corresponding hoisting rod, and the lower end face of each internal hanging block is an irregular slope. The internal hanging blocks are fixedly welded to the lower ends of the hoisting rods, and stiffening plates are welded to the front side and the rear side of each internal hanging block respectively. The transverse connecting rod is formed by a connecting plate clamped between the upper ends of the hoisting rods, and the connecting plate is fixed to the hoisting rods at the two ends through cylindrical pins. The internal hanging type hoisting tool for hoisting conveying of coiled strip steel has the advantages of being simple in structure, convenient to use, safe, reliable, high in use efficiency and the like.

Description

technical field [0001] The invention relates to an inner-hanging spreader used for hoisting coils and steel strips, and belongs to the technical field of lifting tools. Background technique [0002] Coiled steel strip is coiled into coils so that it can be conveniently used and lifted. It occupies a small area and is heavy in weight. It is difficult to lift it to a certain place conveniently with general lifting equipment. For example, the usual external hanger clamps the steel coil on the outer side of the coil, which will easily cause loose coils during the hoisting process, and the spreader will be disengaged, which will seriously cause safety accidents; What have is to carry out hook type hoisting after being tied up by conventional sling, but this kind of sling is bound one, and uses comparatively troublesome, and efficiency is low, and the 2nd, untie accident also easily takes place, and safety is poor. Contents of the invention [0003] The object of the present in...

[0002] Coiled steel strip is coiled into coils so that it can be conveniently used and lifted. It occupies a small area and is heavy in weight. It is difficult to lift it to a certain place conveniently with general lifting equipment. For example, the usual external hanger clamps the steel coil on the outer side of the coil, which will easily cause loose coils during the hoisting process, and the spreader will be disengaged, which will seriously cause safety accidents; Some are hooked after being bound by conventional slings, but this kind of sling is more troublesome and inefficient to use, and second, it is also prone to loosening accidents and poor safety.
