[0016] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0017] like Figures 1 to 3 As shown, the steel beam handling device of the utility model includes a support 10, a lifting ring 11 is fixed on the top of which, a pressure block 21 is provided at the center of the support 10 for sliding up and down, for pressing the upper surface of the steel beam 12, and inclined surfaces 22 are provided on both sides of the pressure block 21; a clamping rod 23 is rotatably provided at the bottom of the support 10, the upper end of the clamping rod 23 can contact with the inclined surface 22 and slide along it, and the lower end of the clamping rod 23 can contact and clamp the side of the steel beam 12.

[0018] The support 10 is placed above the steel beam 12 to be transported, and the pressure block 21 is controlled to slide downward along the support 10 and press the upper surface of the steel beam 12. At the same time, the inclined surfaces 22 on both sides of the pressure block 21 interact with the upper end of the clamping rod 23 to drive the clamping rod 23 to rotate, so that the lower end of the clamping rod 23 contacts and clamps the side of the steel beam 12, so as to clamp and fix the upper surface and both sides of the steel beam 12, and then transport it through the lifting ring 11 on the support 10. There is no need to weld the lifting ring 11 on the steel beam 12, which improves the transportation efficiency and facilitates disassembly to avoid damage to the steel beam 12.

[0019] Preferably, the inclined surface 22 is inclined from top to bottom, from the edge of the pressing block 21 to the center thereof.

[0020] When the pressing block 21 slides downward along the support 10 , the inclined surface 22 can drive the clamping rod 23 to rotate, specifically, drive the upper end of the clamping rod 23 to rotate outward and the lower end to rotate inward, thereby clamping the side of the steel beam 12 .

[0021] Preferably, the clamping rod 23 includes a connecting rod 24 and a clamp 25. The middle part of the connecting rod 24 is rotatably connected to the support 10, the lower end of the connecting rod 24 is fixed to one end of the clamp 25, and the other end of the clamp 25 is set toward the steel beam 12 and can contact and clamp the side of the steel beam 12.

[0022] The lower end of the connecting rod 24 and one end of the clamp 25 are preferably fixed vertically.

[0023] Among them, the upper and lower edges of the other end of the clamp 25 are rounded to avoid damage to the steel beam 12; a protective layer can also be set on the contact part of the clamp 25 with the steel beam 12 to further avoid damage to the steel beam 12.

[0024] Among them, technical personnel in this field can set the shape and size of the clamp rod 23 according to actual applications, so that the device can clamp and carry different types of steel beams 12, such as I-beams, square steels, channel steels, etc., and can clamp their upper and side parts.

[0025] Preferably, a contact roller 26 is rotatably provided at the upper end of the connecting rod 24 , and the outer surface of the contact roller 26 contacts the inclined surface 22 to reduce the wear of the contact portion between the connecting rod 24 and the inclined surface 22 .

[0026] Preferably, a mounting rod 27 is fixed to the bottom of the support 10, and a rotating shaft 28 is fixed to the lower end of the mounting rod 27. The rotating shaft 28 is rotatably connected to the middle part of the connecting rod 24. A torsion spring 29 is mounted on the rotating shaft 28. One end of the torsion spring 29 is fixed to the connecting rod 24, and the other end is fixed to the mounting rod 27, so that the two clamping rods 23 remain in an open state with the upper end facing inward and the lower end facing outward, so as to facilitate the insertion of the steel beam 12 for clamping.

[0027] Preferably, a through hole 31 is opened on the support 10 , a bolt 32 is arranged in the through hole 31 , the lower end of the bolt 32 is fixed to the pressing block 21 , and a nut 33 is rotatably provided on the top of the support 10 , and the nut 33 is threadedly connected to the bolt 32 .

[0028] Rotating the nut 33 drives the bolt 32 to move along the through hole 31 , driving the pressing block 21 to slide up and down along the support 10 .

[0029] Under the combined action of the inclined surfaces 22 on both sides of the pressing block 21 and the contact rollers 26 , the pressing block 21 can only slide up and down but will not rotate around the bolts 32 .

[0030] Preferably, two lifting rings 11 are arranged relatively to the center of the support 10 to ensure the stability and safety of the steel beam 12 during transportation and reduce shaking.

[0031] The working principle of the utility model is as follows:

[0032] The support 10 is placed above the steel beam 12 to be transported, and the nut 33 is rotated to drive the bolt 32 to move downward along the through hole 31, and the pressure block 21 is driven to slide downward along the support 10 to press the upper surface of the steel beam 12. At the same time, the inclined surfaces 22 on both sides of the pressure block 21 interact with the upper end of the clamping rod 23 to drive the clamping rod 23 to rotate. Specifically, the upper end of the clamping rod 23 is driven to rotate outward and the lower end is driven inward, so that the clamp head 25 at the lower end of the clamping rod 23 contacts and clamps the side of the steel beam 12, so as to clamp and fix the upper surface and both sides of the steel beam 12, and then transport it through the lifting ring 11 on the support 10. There is no need to weld the lifting ring 11 on the steel beam 12, which improves the transportation efficiency and facilitates disassembly to avoid damage to the steel beam 12.

Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
