Problems solved by technology

However, there are also defects in the hoisting process of steel structural members. The width of the above two kinds of hooks is relatively narrow, which leads to a small contact surface between the hook and the steel structural member during the hoisting process of the steel structural member, and it is easy to During the hoisting process, the deformation of steel structural members is caused, especially when hoisting some steel structural members with low out-of-plane rigidity, the deformation is more obvious. For example, when hoisting steel plates, U-ribs, H-shaped steel, etc., deformation can affect the quality of components

Embodiment 1

[0027] Example 1, such as Figure 1-4 As shown, a U-shaped rib special hook provided in this embodiment includes a hook body 1 formed by bending a steel plate for hooking a steel member 4, a wire rope installation mechanism is provided on the hook body 1, and the hook body 1 passes through The wire rope installation mechanism is installed on the crane wire rope 3, and the width of the hook body 1 is 10-35cm.

[0028] The invention is simple in structure, scientific and reasonable in design, and easy to use. It can effectively increase the contact area between the hook and the steel component when hooking the steel component, thereby reducing the deformation of the steel component and ensuring the quality of the steel component after hoisting. The invention is especially suitable for U-shaped ribs for hoisting hooks.

Embodiment 2

[0029] Example 2, such as Figure 1-4 As shown, a U-shaped rib special hook provided in this embodiment includes a hook body 1 formed by bending a steel plate for hooking a steel member 4, a wire rope installation mechanism is provided on the hook body 1, and the hook body 1 passes through The wire rope installation mechanism is installed on the crane wire rope 3, and the width of the hook body 1 is 10-35cm. The wire rope installation mechanism includes a U-shaped groove 2 opened on the hook body 1, and a screw rod 5 detachably installed on the hook body 1 to close the opening of the U-shaped groove 2. The crane wire rope 3 is passed through the U-shaped groove 2 and bolted Hang on the screw 5.

[0030] On the basis of Example 1, this embodiment provides the specific structure of the wire rope installation mechanism. The wire rope installation mechanism includes a U-shaped groove 2 opened on the hook body 1, and a U-shaped groove 2 that is detachably installed on the hook bod...

Abstract

The invention discloses a special lifting hook for a U-shaped rib. The technical problem that in the prior art, a steel member is prone to being deformed during lifting, and the quality of the steel member is affected due to the width of a lifting hook is small is solved. The special lifting hook comprises a hook body which is formed by bending a steel plate and used for hooking a steel member, a steel wire rope installation mechanism is arranged on the hook body, the hook body is installed on a crane steel wire rope through the steel wire rope installation mechanism, and the width of the hook body is 10-35 cm. The special lifting hook is simple in structure, scientific and reasonable in design and convenient to use, the contact area between the lifting hook and the steel member can be effectively increased when the lifting hook hooks the steel member, deformation of the steel member is reduced, and the quality of the lifted steel member is guaranteed; and the special lifting hook for the U-shaped rib is particularly suitable for lifting and hooking of the U-shaped rib.

Description

technical field [0001] The invention belongs to the technical field of hoisting equipment for steel components, and in particular relates to a special hook for U-shaped ribs. Background technique [0002] In the process of steel structure processing, it is often necessary to hoist the steel structure components. During the hoisting of steel structural members, the hook used to hook the steel structural members is a necessary part for hoisting. Hooks used in steel structure hoisting operations are generally divided into forged hooks and sheet hooks. These two kinds of hooks have obvious advantages in the hoisting process, and their own cross-sectional area is large and the bearing capacity is large. However, there are also defects in the hoisting process of steel structural members. The width of the above two kinds of hooks is relatively narrow, which leads to a small contact surface between the hook and the steel structural member during the hoisting process of the steel s...
