Description

Lifting hook

Technical Field

The utility model relates to a lifting hook especially relates to a make the hook-shaped body of lifting hook bottom lean out and make hoist and mount thing be in the lifting hook of tilt state.

Background

In order to cooperate hoisting machinery to hoist articles, the lifting hook is a necessary part in the prior art, generally consists of a lifting ring, a connecting part and an arc-shaped bottom hook, and in order to enable a hoisted object to automatically find the gravity center, the lifting ring is generally positioned at the top of the center of the connecting part, and the bottom hook is positioned at the bottom of the center of the connecting part, so that the hoisted object does not have an inclined state in the hoisting process.

However, the defects of the lifting hook in the prior art are very obvious, the existing lifting hook needs to be matched with a lifting rope for use, the lifting rope generally uses a high-strength steel wire lifting rope, the flexibility of the steel wire lifting rope is poor, and two steel wire ropes are generally used, therefore, in the lifting use process, one of the lifting ropes needs to be hung on the lifting hook manually, in order to prevent the lifting rope from being separated, the lifting rope is generally continuously centered or partially lifted by the lifting hook manually, the lifting rope is prevented from falling off, and even if the two modes are adopted, the state that the second lifting rope is not easy to hang on the lifting hook can also occur due to the fact that the lifting hook is in a vertical state during the operation of the other lifting rope.

Moreover, the design that the lifting hook automatically searches for the center of gravity in the prior art cannot meet the requirement for lifting the plate-shaped body in a semi-vertical state, and the lifting hook is horizontal after being lifted and is not beneficial to secondary lifting.

Disclosure of Invention

For solving the problem that prior art exists, the utility model provides a make the lifting hook remain the tilt state throughout to make things convenient for hanging of lifting rope to go into, simultaneously the utility model discloses a with the end hook design for the platelike body, realize that the lifting rope can not remove along with the focus, thereby keep hoisting and hanging the thing and be in controllable tilt state, thereby realize hoisting and hanging to keep the tilt state by hoisting and hanging the thing after accomplishing, make things convenient for the secondary handling.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the lifting hook comprises rings, connecting portion and arc end hook, rings and end hook are located the top and the bottom of connecting portion respectively, rings set up in connecting portion top side, connecting portion are linear type connecting portion, the hook is hook at the bottom of the arc of platelike body, hook setting is in another side bottom of connecting portion relative with rings at the bottom of the arc.

Preferably, the rings are square-like, the included angle between each two adjacent rings and the connecting part are integrally formed, and an included angle is formed between one side edge of each square-like ring and the connecting part.

Preferably, the included angle is greater than 40 °.

Preferably, the connecting part is a plate-shaped body.

Compared with the prior art, the beneficial effects of the utility model reside in that: because the lifting ring and the bottom hook are respectively positioned at two sides of the connecting part, the position of the bottom hook is not the central position, so that the inlet of the bottom hook is kept to incline outwards; the utility model discloses simultaneously with the end hook design for the platelike body, consequently, through the adjustment of lifting rope before the hoist, keep the tilt state, after the lifting hook rises, under the friction of twice edges and corners, the lifting rope is difficult for removing to the tilt state of artifical adjustment when keeping hoisting makes things convenient for the secondary handling.

Drawings

For further explanation of the present invention, the drawings and embodiments are listed below.

Fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a schematic view of the simulation using state of the present invention.

Detailed Description

As shown in fig. 1-2, the lifting hook is composed of a lifting ring 1, a connecting portion 2 and an arc-shaped bottom hook 3, wherein the lifting ring 1 and the bottom hook 3 are respectively located at the top and the bottom of the connecting portion 2, the lifting ring 1 is arranged at the top side end of the connecting portion 2, the connecting portion 2 is a linear type connecting portion, the arc-shaped bottom hook 3 is a plate-shaped arc-shaped bottom hook, and the arc-shaped bottom hook is arranged at the bottom of the other side end of the connecting portion 2 opposite to the lifting ring 1.

Preferably, rings 1 are square-like, and the contained angle department and connecting portion 2 integrated into one piece of square-like rings, a side of square-like rings forms the contained angle with connecting portion 2.

Preferably, the included angle is greater than 40 °.

Preferably, the connecting portion 2 is a plate-like body.

Obviously, the above embodiment is only one example of the present invention, and any simple improvement in the structure or principle provided by the present invention is within the protection scope of the present invention.

Claims (4)

1. The lifting hook comprises rings, connecting portion and arc end hook, rings and end hook are located the top and the bottom of connecting portion respectively, its characterized in that rings set up in connecting portion top side, connecting portion are linear type connecting portion, hook is hook at the bottom of the arc of platelike body, hook setting is in another side bottom of connecting portion relative with rings at the bottom of the arc.

2. A lifting hook as claimed in claim 1, wherein the lifting ring is square-like, the included angle between the corner of the square-like lifting ring and the connecting portion is integrally formed, and an included angle is formed between one side edge of the square-like lifting ring and the connecting portion.
