Problems solved by technology

When using lifting tools to lift, it is necessary to rely on steel plate hooks. The existing steel plate hooks often appear to be not clamped tightly during use. When the lifting tools are lifted, the steel plate will tilt or fall down, and it needs to be clamped again. Once, the operation efficiency is low and the lifting safety is poor

Embodiment Construction

[0012] The present invention is described below in conjunction with accompanying drawing.

[0013] as attached figure 1 The shown steel plate hook of the present invention includes a crotch 1, a rotary block 2 and a pin 3; the rotary block 2 is rotatably connected to one end of the crotch 1 through a pin 3; The inner surface of the other end of the hook 1 is provided with sawtooth 5; the top of the rotary block 2 is provided with a fixed hanging hole 4; the tail end of the rotary block 2 is an arc surface 6, and the arc surface 6 is provided with a serration 5; The shape of the sawtooth on the hook 1 is different from the sawtooth on the rotating block 2 .

[0014] as attached figure 2 The shown steel plate hook of the present invention, when in use, put the steel plate 7 in the crotch 1, and then use the lifting tool to lift the steel plate hook through the fixed lifting hole 4, and the crotch 1 is under the weight of the steel plate 7. The function of the steel plate 6 w...

Abstract

The invention discloses a lifting hook of a steel plate. The lifting hook of the steel plate comprises a hook, a rotary fixture block and a pin shaft, wherein the rotary fixture block is rotationally connected with one end of the hook; sawteeth are arranged at the inner side of the other end of the hook; a fixed lifting hole is arranged at the top end of the rotary fixture block; the tail end of the rotary fixture block forms an arc surface; and sawteeth are arranged on the arc surface, and the sawteeth arranged on the hook are different from the sawteeth arranged on the rotary fixture block in shape. According to the lifting hook of the steel plate, the steel plate is firmly fixed when being clamped, and a lifting tool does not easily generate the phenomenon that the steel plate inclines or falls down in a lifting process without secondary clamping, so the lifting security is improved when the operation efficiency is increased.

Description

technical field [0001] The invention relates to a suspension hook, in particular to a suspension hook used for steel plate handling. Background technique [0002] The steel plate is a flat steel material that is poured with molten steel and pressed after cooling, and is widely used in the machinery manufacturing industry. In machinery manufacturing enterprises, some small and thin steel plates can be directly transported manually, but this kind of steel plates cannot meet the needs of manufacturing well and are not widely used. And some large and thick steel plates are widely used because of their good strength and other characteristics that can well meet the needs of manufacturing. Due to the heavy weight of large and thick steel plates, they cannot be directly transported manually, and they need to be hoisted with lifting tools. When using lifting tools to lift, it is necessary to rely on steel plate hooks. The existing steel plate hooks often appear to be not clamped ti...
