Description

Hanging beam

Technical Field

The invention relates to the technical field of hoisting machinery, in particular to a hoisting beam for hoisting an industrial device module.

Therefore, strict requirements are imposed on the material, diameter and length of the long rope, such as: a steel wire rope is adopted. In addition, the requirement of the minimum bending radius of the wire rope directly affects the diameter of the pulley. If in order to protect the pulley body not by wearing and tearing and reduce the restraint of pulley diameter, and adopt the mode of changing the rope material and change and use the rope that minimum bend radius required little, like the nylon rope, then can cause lifting capacity greatly reduced. Therefore, in order to meet the requirement of wide branch of the hanging point, the invention also needs to invent an accessory which can be matched with the main beam part of the hanging beam.

In this embodiment, the upper hanging ring 21 and the lower hanging ring 22 are disposed on the upper edge and the lower edge of the connecting plate 12, and the lower hanging ring 22 is disposed outside the upper hanging ring 21.

In practical use, the upper hanging ring 21 and the lower hanging ring 22 are not limited to be disposed on the upper edge and the lower edge of the connecting plate 12, and they may be disposed above and below the central axis M, respectively.

Referring to fig. 4, preferably, the upper hanging ring 21 and the lower hanging ring 22 of each group of hanging rings are distributed in a staggered offset manner; the vertical point of the central point c of the lower hanging ring 22 on the central axis M is a point d, the connecting line between the central point b and the vertical point d of the upper hanging ring 21 is L, and the connecting line L forms an included angle of 60 degrees with the central axis M; the lower hanging ring 22 has a downward load gravity G, the upper hanging ring 21 has a pulling force F from the rigging of the hanging hook 200, and when the direction of the pulling force F coincides with the connecting line L, the hoisting bending moment is completely eliminated.

When the single-hook hoisting is carried out, the bending moment generated by the upper hoisting ring 21 to the main beam 10 is greatly reduced due to the offset distance of the upper hoisting ring 21 and the lower hoisting ring 22; even when the included angle of the rigging of the upper hoisting ring 21 reaches a preset angle, the hoisting bending moment can be thoroughly eliminated, the hoisting without bending moment is realized, and the service performance of the hoisting beam 100 is greatly improved.
