[0002] Angle steel is a kind of steel widely used in the fields of construction, machinery, electricity, etc. It is a long steel strip with two sides at right angles. It is usually made of ordinary carbon structural steel and low-alloy steel. Due to the shape of angle steel, the surface of angle steel is relatively smooth, and its hoisting process has always been a technical problem. Traditional angle steel hoisting methods usually rely on manual operation, such as using ropes, hooks and other tools for hoisting.

[0003] In order to improve the stability and efficiency of hoisting, it is necessary to use a specific device for hoisting. For example, in the Chinese patent with the announcement number "CN220723312 U", a clamping device for angle steel for power towers is disclosed. Although the device can hoist the angle steel, due to the particularity of its hoisting structure, only one angle steel can be hoisted at a time, and the hoisting efficiency is low. Utility Model Content

[0028] Through the above technical scheme, when personnel need to hoist the angle steel, one end of the angle steel is inserted into the first side groove 11 on the first positioning frame 13, and then the other end of the angle steel is inserted into the second side groove 26 on the second positioning frame 21, and the connecting steel cable 16 is pulled to make the free end of the connecting steel cable 16 pass through the connecting hole 22 of the second side plate 28 on the second positioning frame 21, and the limiting screw 25 on the second side plate 28 is rotated to make one end of the limiting screw 25 contact the connecting steel cable 16, so that the angle steel is fixed between the second positioning frame 21 and the first positioning frame 13, and then the lifting equipment is connected to the second positioning frame 21 and the first positioning frame 13, the first side plate 14 is supported by the first positioning frame 13, and the connecting steel cable 16 is supported by the first side plate 14, and the second positioning frame 21 and the first positioning frame 13 are moved by the lifting equipment, and then the angle steel is hoisted.

[0029] In addition, in the present invention, a sharp protrusion is formed at the free end of the connecting steel cable 16. When a person passes the connecting steel cable 16 through the connecting hole 22, the sharp protrusion cooperates to facilitate the connecting steel cable 16 to be connected to the second side plate 28.

[0030] In order to facilitate the connection of the device with the lifting equipment, such as Figure 1-Figure 2 As shown, a side of the second positioning frame 21 away from the first positioning frame 13 and a side of the first positioning frame 13 away from the second positioning frame 21 are both fixedly connected with a connecting piece for connecting a lifting device.

[0031] In this embodiment, the angle steel is placed between the first side groove 11 on the first positioning frame 13 and the second side groove 26 on the second positioning frame 21, the connecting steel cable 16 is pulled so that the free end of the connecting steel cable 16 passes through the connecting hole 22 of the second side plate 28 on the second positioning frame 21, and the limiting screw 25 on the second side plate 28 is rotated so that one end of the limiting screw 25 contacts the connecting steel cable 16, so that the angle steel is fixed between the second positioning frame 21 and the first positioning frame 13, and then the lifting equipment is connected to the second positioning frame 21 and the first positioning frame 13, the first side plate 14 is supported by the first positioning frame 13, the connecting steel cable 16 is supported by the first side plate 14, the lifting equipment is connected through the connecting parts on the first positioning frame 13 and the second positioning frame 21, and the second positioning frame 21 and the first positioning frame 13 are moved by the lifting equipment, and then the angle steel is hoisted.

[0032] Specifically, in one embodiment, regarding the above-mentioned connecting member:

[0033] like Figure 1-Figure 2 , Figure 4 , Figure 7As shown, the connecting member includes a second connecting rod 29 and a first connecting rod 18, and the second connecting rod 29 and the first connecting rod 18 are respectively fixedly connected to one side of the second positioning frame 21 and the first positioning frame 13, and the free ends of the second connecting rod 29 and the first connecting rod 18 are respectively fixedly connected to the second traction ring 23 and the first traction ring 17.

[0034] In this embodiment, when personnel need to connect the lifting equipment, the lifting equipment is connected to the second traction ring 23 and the first traction ring 17 respectively, and the second positioning frame 21 and the first positioning frame 13 are respectively supported by the second positioning frame 21 and the first positioning frame 13, and the second traction ring 23 and the first traction ring 17 are respectively supported by the second positioning frame 21 and the first positioning frame 13. The second positioning frame 21 and the first positioning frame 13 are moved by the lifting equipment, and the angle steel can be lifted.

[0035] When the first side groove 11 supports the length end of the angle steel, in order to make the device more stable when hoisting the angle steel, Figure 2 As shown, a plurality of first springs 15 are fixedly connected to the inner wall of the first side groove 11 , and a first positioning column 12 is fixedly connected to the free end of the first spring 15 .

When the first positioning column 12 is squeezed by the angle steel, the squeezed first positioning column 12 sinks, and the squeezed first positioning column 12 compresses the first spring 15, thereby generating a reaction force that resists the angle steel. The first positioning column 12 that is not squeezed will limit the angle steel, making the angle steel more stable during hoisting.

[0037] When the second side groove 26 supports the length end of the angle steel, in order to make the device more stable when hoisting the angle steel, such as Figure 6 and Figure 8 As shown, a plurality of second springs 27 are fixedly connected to the inner wall of the second side groove 26 , and a second positioning column 24 is fixedly connected to the free end of the second spring 27 .

[0038] In this embodiment, when the angle steel is placed inside the second side groove 26, the second spring 27 is supported by the second side groove 26, and the second positioning column 24 is supported by the second spring 27. When the second positioning column 24 is squeezed by the angle steel, the squeezed second positioning column 24 sinks, and the squeezed second positioning column 24 compresses the second spring 27, thereby generating a reaction force that resists the angle steel. The second positioning column 24 that is not squeezed will limit the angle steel, making the angle steel more stable during hoisting.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
