Welding lifting hook with good anti-stripping property

Abstract

The invention discloses a welding lifting hook with good anti-stripping property, wherein the welding lifting hook includes a hook body and a round head. The round head is located at the tail end of the hook body and is fixedly connected with the hook body; a rotating shaft is arranged at one end of the outer wall of the hook body, and one end of the rotating shaft is rotatingly connected with ananti-stripping device; a fixing hole is arranged on the surface of one end of the anti-stripping device; a clamping groove is arranged at the inner side of the round head. With the arrangement of a fixing rod, the anti-stripping device can be fixed, so a condition of looseness of the anti-stripping device is prevented, at the same time, the influence of external factors on the anti-stripping device can also be prevented, and the anti-stripping property of the lifting hook is ensured; because a lifting ring is made of an insulation material, electric shock accidents and burned damage of cranesand appliances caused by poor ground connection of welding current can be effectively prevented, and accidents caused by electric shock and leakage are prevented; through arrangement of transverse reinforcing ribs and vertical reinforcing ribs, the structural strength of the hook body can be strengthened, and local deformation and fracture of the hook body cannot appear in the process of use, so the lifting hook is suitable for mass production and use.

Description

technical field [0001] The invention relates to a welding hook, in particular to a welding hook with good fall-off resistance. Background technique [0002] The hook is the most common type of spreader in hoisting machinery. The hook is often suspended on the wire rope of the hoisting mechanism by means of pulley blocks and other components. The hook should have sufficient strength and rigidity, so the material and There are strict requirements for processing. Forged hooks are not allowed, and materials with low impact toughness are not allowed. Hooks are divided into forged hooks and laminated riveted plate hooks. Forged hooks are usually made of good plasticity and are not easy to produce time-dependent strain Brittle 20-gauge high-quality mild steel is forged in one piece and then annealed. [0003] However, most of the hooks currently on the market have a single function. Most of the traditional hooks are only a single anti-off device to prevent the wire rope from falli...

Problems solved by technology

[0003] However, most of the hooks currently on the market have a single function. Most of the traditional hooks are only a single anti-off device to prevent the wire rope from falling off. This does not provide absolute anti-off performance. After a long time of use, The anti-detachment device may not get stuck, or the anti-detachment device may become loose due to some factors during use, which will cause the wire rope to fall off, resulting in unpredictable losses, and the overall structure of the traditional hook Not strong, prone to breakage
