Straight-handle double-hook lifting hook suitable for flat sling and lifting equipment

Abstract

The invention provides a straight-handle double-hook lifting hook suitable for a flat sling. The straight-handle double-hook lifting hook comprises a straight handle and a transverse handle, the lowerend of the straight handle is fixed to the middle of the transverse handle, vertically-upward hook parts are arranged at the two ends of the transverse handle respectively, and ball head structures are arranged at the top ends of the hook parts; the transverse handle is of a flat structure, the upper surface of the transverse handle is a horizontal bearing face, and the two side faces of the transverse handle are vertical faces; the inner surfaces of the hook parts are perpendicular to the bearing surface; the inner surfaces of the hook parts and the bearing surface are in arc transition, andthe bearing surface and the vertical faces are in fillet transition; and the straight handle comprises a fixed section, a matching shaft section and a connecting section, the fixed section is fixed with the transverse handle, and an external thread structure is arranged on the connecting section. According to the lifting hook provided by the invention, the bearing face and the vertical faces makecontact with the sling, the overall stress face of the lifting hook is increased, stress is uniform, the sling is not damaged, the service life of the sling is prolonged, the contact position of thesling and the lifting hook is not prone to deformation, and the lifting stability is high.

Description

technical field [0001] The invention belongs to the technical field of heavy machinery and equipment, and in particular relates to a straight-handle double-hook hook suitable for flat slings and hoisting equipment. Background technique [0002] The hook is a commonly used lifting facility. In the prior art, most of the hooks are designed with curved grooves. Since most of the slings used in the current market are wide-faced slings, when the curved groove type hook structure is used, the contact between the sling and the hook It is easy to deform, and the contact working surface between the sling and the hook is small, which changes the theoretical bearing capacity of the sling, reduces the service life of the sling, reduces the lifting stability, and has no guarantee for safety. Therefore, improvements are required. Contents of the invention [0003] In view of this, the present invention aims to overcome the defects in the prior art, and proposes a straight handle double...
