Description

Technical Field

[0001] This utility model belongs to the field of lifting tool technology, specifically relating to a special-shaped steel lifting tool. Background Technology

[0002] Irregularly shaped steel sections are long and narrow, posing two major problems when using chains and steel plate hooks for lifting: first, it is difficult to accurately position the lifting point; second, after lifting, they are prone to shifting to one side, leading to the risk of slippage during hoisting. While there are many types of standard lifting tools available on the market, none can effectively solve these problems.

[0003] It is essential to develop a lifting tool for irregularly shaped steel, taking into account the weight of the object to be lifted and the shape of the workpiece. Summary of the Invention

[0004] The purpose of this utility model is to provide a lifting device that can adapt to different weights and different irregular steel shapes and ensure force balance.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A special-shaped steel lifting device is characterized in that it comprises a triangular lifting plate with a certain thickness and front and rear lifting hooks connected thereto and capable of rotation; wherein, the lifting plate is provided with lifting holes; the front and rear lifting hooks connected to the bottom of the triangular lifting plate are connected to the bottom of the lifting plate; the front and rear lifting hooks are outward-flaring structures with a tightening structure at their bottom.

[0006] The additional technical features constituting the above-mentioned special-shaped steel lifting tool also include: —Fixing nuts are provided on the outside of the front and rear lifting hooks; —To reduce the weight of the triangular lifting plate, weight-reducing holes are provided on its flat surface; —To facilitate the lifting of irregularly shaped parts of different sizes by the front and rear lifting hooks, the lifting hooks are flared outwards, so that there is a certain gap between the bottoms of the two hooks; —A nut and a screw are provided between the front and rear lifting hooks to adjust the initial distance; —Anti-slip grooves are provided on the lower inner side of the front and rear lifting hooks.

[0007] Compared with the prior art, the special-shaped steel lifting tool provided by this utility model has the following advantages: First, since the spacing and bending angle of the hooks constituting the lifting tool can be freely adjusted, it can achieve multiple uses for one lifting; Second, since the main body of the lifting tool is made of a certain thickness of steel plate, the overall load-bearing strength is guaranteed; Third, during the lifting, the lifting tool and the special-shaped steel are tightly engaged, the force is evenly distributed and will not fall off; Fourth, the special-shaped steel lifting tool is combined with an anti-slip design to effectively prevent the workpiece from shifting, achieve stable lifting, and fundamentally solve the safety hazards of traditional lifting. Attached Figure Description

[0008] Figure 1 This is a structural schematic diagram of a special-shaped steel lifting tool according to the present invention; Figure 2 This is a side view diagram of the structure that constitutes the aforementioned irregular steel lifting device. Detailed Implementation

[0009] The structure and working principle of the irregular steel lifting tool provided by this utility model will be further described in detail below with reference to the accompanying drawings.

[0010] like Figure 1 The diagram shown is a structural schematic of a special-shaped steel lifting device provided by this utility model. The structure constituting the special-shaped steel lifting device includes: a lifting plate 2 with a thickness of at least 10 millimeters, a triangular lifting plate 2 with lifting holes 1, and front and rear lifting hooks 3 and 4 connected to and rotatable thereto, forming a lifting device; wherein, the front and rear lifting hooks 3 and 4 connected to the bottom of the triangular lifting plate 2 are connected to the bottom of the lifting plate 2, and fixing nuts 5 are provided on the outer side of the front and rear lifting hooks 3 and 4; the front and rear lifting hooks 3 and 4 have an outward flared structure, and their bottoms have a tightening structure 6.

[0011] In use, the hook 8 of the hoist 14 is hooked into the lifting hole 1 of the triangular lifting plate 2 to lift it and move it to the upper part of the irregular steel 7; then it is lowered down, and the lifting device consisting of the front and rear lifting hooks 3 and 4 is fastened onto the irregular steel 7, and the lifting device can lift the irregular steel 7. This lifting tool can stably lift irregular parts such as steel sections. During lifting, the lifting device is tightly engaged with the irregular part, the force is evenly distributed and it will not fall off. With the anti-slip design, it effectively avoids the deviation of irregular parts such as steel sections, and achieves stable lifting.

[0012] In the structure that constitutes the aforementioned irregular steel lifting device —In order to reduce the weight of the triangular lifting plate 2 and facilitate its effective connection with the front and rear lifting hooks 3 and 4, weight-reducing holes 9 of different specifications or shapes are provided on its plane; —In order to facilitate the lifting of different sized irregular parts 7 by the front and rear lifting hooks 3 and 4, the lifting hooks 3 and 4 are divided into upper and lower sections 30 and 40, respectively. The upper section 30 is flared outward, so that a certain distance 10 can be formed between the bottom lower section 40 of the two for supporting irregular parts. —In order to enable the hoisting of different sized irregular parts 7 between the front and rear hoisting hooks 3 and 4, a nut 11 and a screw 12 that can adjust the initial distance are set between them. The nut can be rotated on the screw to adjust the distance between the front and rear hoisting hooks 3 and 4 to accommodate the assembly of different sized irregular parts 7. —To facilitate the anti-slip structure of the irregular steel lifting tool, an anti-slip groove 13 is provided on the inner side of the lower part (section) of the aforementioned front and rear lifting hooks 3 and 4 to prevent the irregular part 7 from falling off.
