Abstract

The utility model discloses a lifting hook, which is composed of a connecting ring and a lifting hook body. The cross section of the lifting hook body is I-shaped, the inner sides of the vertical arm and the hook arm of the lifting hook body adopt straight lines, the included angle formed between the two straight lines is between 70 to 90 degrees, the upper transverse surface of the I-shaped cross section of the hook arm of the lifting hook body adopts an arc-shaped surface, and the end head of the hook arm of the lifting hook body adopts an acute angle type. The lifting hook of the utility model has the advantages that the structure is simple, the bearing capacity of the lifting hook with identical quality is high, the application range is wide, the suspended objects cannot be damaged, the lifting hook is uneasy to bend and break, the service lift is long, and the lifting hook is secure and reliable.

Description

A kind of suspension hook

Technical field

The utility model belongs to the hanging device technical field, especially relates to a kind of suspension hook.

Background technology

Suspension hook generally adopts trunk formula suspension hook at present, basically can be suitable for any lifting requirements, range of use is more extensive, but under specific lifting requirements, such as special suspended objects such as lifting steel plate, steel pipes, suspended object then appears easily damaging, even the situation that can't lift, the load-carrying capacity of trunk hook is relatively low simultaneously, can't satisfy the requirement of present large-tonnage lifting, can not adapt to existing lifting requirements.

Summary of the invention

The purpose of this utility model be to improve the deficiency of prior art and provide a kind of simple in structure, equal in quality suspension hook load-carrying capacity height, applied widely, do not damage lifting object, suspension hook and be not easy bending and fracture, long service life, safe and reliable suspension hook.

The purpose of this utility model is to realize like this, a kind of suspension hook, be made up of coupling link, hook, the cross section that is characterized in described hook is an I-shape, and the perpendicular arm of hook and the inboard of hook arm are that the angle α that forms between straight line and two linear arm is between the 70-90 degree.

In order further to realize the purpose of this utility model, can be that the last plane of structure of I-shaped cross-section of the hook arm of hook is a cambered surface.

In order further to realize the purpose of this utility model, the termination that can be the hook arm of described hook is the acute angle formula.

In order further to realize the purpose of this utility model, can be that the last cambered surface width of I-shaped cross-section of the hook arm of hook is the 40-70 millimeter.

Compared with the prior art the utility model has following distinguishing feature and good effect: it is I-shape that the utility model adopts the cross section of hook, changed the cone cross section of existing hook, under the identical situation of the weight of hook, load capacity of the present utility model is more than three times of prior art hook, improved hoisting weight greatly, improved the metal aging resistance of hook simultaneously, prolong service life greatly, more safe and reliable; The perpendicular arm of hook and the inboard of hook arm be the angle α that forms between straight line and two linear arm between the 70-90 degree, so not only can lift by crane the lifting thing that existing suspension hook is fit to, the while can better be fit to the lifting of steel plate, steel pipe, has enlarged Applicable scope; The last plane of structure of the I-shaped cross-section of hook is a cambered surface, can well coincide with suspended object, especially the lifting face of steel pipe like this, has avoided the damage suspended object; The termination of the hook arm of hook is the acute angle formula, and the below that this structure can be easily, suspended object is inserted in the labour-saving becomes in lifting.

The specific embodiment

Embodiment 1, a kind of suspension hook, with reference to Fig. 1, Fig. 2, it is the coupling link 1 that on hook 2, is provided with its one, the cross section of hook 2 is an I-shape, the perpendicular arm 3 of hook 2 and the inboard of hook arm 4 be the angle α that forms between straight line and two linear arm between the 70-90 degree, the angle α of present embodiment is 80 degree, this constitutes a kind of structure of the present utility model.

Embodiment 2, and a kind of suspension hook is with reference to Fig. 1, Fig. 3, be on the basis of embodiment 2, the last plane of structure of the I-shaped cross-section of the hook arm 4 of hook 2 is a cambered surface, and last cambered surface width is the 40-70 millimeter, this structure especially is fit to the lifting steel pipe, and other and embodiment 1 are identical.

Embodiment 3, and a kind of suspension hook with reference to Fig. 2, Fig. 4, is on the basis of embodiment 1, and the termination of the hook arm 4 of hook 2 is the acute angle formula, and this structure especially is fit to plate shaped suspended object, and other and embodiment 1 are identical.
