Description

Technical Field

[0001] The utility model relates to the technical field of steel beam hoisting, in particular to a hoisting device used for I-beam transportation. Background Art

[0002] I-beams are a type of steel commonly used in steel structure buildings. There are multiple processes in the production of I-beams. When the I-beams need to be transported or transferred, they are generally hoisted by wrapping wire ropes around both ends of the I-beams. This method requires a ground clearance between the ends of the I-beams and the ground for threading or hanging the wire ropes. In addition, the I-beams are prone to deflection and slipping off the ends during hoisting. Another method is to drill holes in the upper flange plate of the I-beams to connect the hoisting ropes, or to weld lifting ears on the upper flange plate of the steel pipe piles, but this will cause damage to the I-beams.

[0003] Therefore, some I-beam lifting devices have appeared. Patent CN217947336U discloses an I-beam lifting device, which includes two sets of lifting devices, each set of lifting devices includes two suspension rods, each suspension rod is equipped with a horizontal support rod at the lower end, and each suspension rod is fixedly connected to an inclined rod at the upper end. The inclined rods at the upper ends of the two suspension rods are in an "eight" shape. Whether the I-beam is placed upright or lying, it can be lifted, which effectively solves the problem of inconvenient installation of I-beam lifting devices and easy slipping during lifting. However, this method has a complex fixture structure, and the steel is supported by the support rod without a fixing device. If the I-beam deflects during lifting, the support rod is easy to slip from the end. Utility Model Content

[0026] The present invention is described in detail below with reference to the accompanying drawings and in combination with embodiments:

[0027] Embodiment 1:

[0028] like Figures 1 to 3 As shown, the present embodiment provides a lifting device for transporting an I-beam 11, comprising two groups of lifting tools arranged at both ends of the I-beam 11, each group of lifting tools comprising a base plate 1 and a lifting plate 2, a slot 3 is provided on the base plate 1, and the length direction of the slot 3 is along the center of one side of the base plate 1 toward the center of the base plate 1, one end of the lifting plate 2 is fixed on the rectangular base plate 1 parallel to the length direction of the slot 3, and the other end of the lifting plate 2 is suspended directly above the slot 3 to form a through slot 4 with the base plate 1, the through slot 4 and the slot 3 are connected to form a socket for the flange plate of the I-beam 11 to pass through, and a fixing part for fixing the I-beam 11 is provided on the lifting plate 2 above the slot 3.

[0029] Specifically, in order to facilitate the insertion of the I-beam 11, the slot 3 and the through slot 4 form an inverted T-shaped socket, which is the same as the cross section of the flange plate of the I-beam 11, and the T-shaped socket facilitates the insertion of the flange plate of the I-beam 11. The slot 3 and the through slot 4 are parallel and the lengths of the slot 3 and the through slot 4 are equal.

[0030] In order to enable the crane to pull the lifting rope to lift the I-beam 11 or H-shaped steel, a lifting hole 10 is provided at one end of the lifting plate 2 located above the slot 3. In this way, the I-beam 11 can be lifted by the lifting tools installed at both ends of the I-beam 11.

[0031] Specifically, the fixing member includes a fastening bolt 5, and the hanging plate 2 above the slot 3 is provided with a screw hole threadedly connected to the fastening bolt 5. In order to increase the contact area between the fixing member and the I-beam 11 and increase the fixing strength, a fixing plate 6 is installed at one end of the fastening bolt 5 close to the slot 3. In order to increase the friction between the fixing plate 6 and the flange plate of the I-beam 11 and reduce the shaking caused by the relative sliding between the I-beam 11 and the fixing plate 6, an anti-sliding block 7 is provided on the surface of the fixing plate 6 facing the slot 3. The fixing plate 6 can be fixed to the end of the fastening bolt 5 so that the fixing plate 6 moves downward with the fastening bolt 5 and presses against the flange plate. The fastening bolt 5 and the fixing plate 6 can also be connected by threads, and screw holes are provided on the upper surface of the fixing plate 6. In this way, when the I-beam 11 is inserted into the socket, the upper surface of the base plate 1 contacts the lower surface of the flange plate, and then the fixing plate 6 is placed in the gap between the flange plate and the hanging plate 2 in the through groove 4, and the fastening bolt 5 is placed in the screw hole on the fixing plate 6. The fastening bolt 5 is adjusted so that the fixing plate 6 presses against the flange plate.

[0032] Similarly, in order to prevent the relative sliding between the bottom plate 1 and the I-beam 11 from causing the I-beam 11 to shake during the hoisting process, anti-skid protrusions 8 are provided on the surface of the bottom plate 1 facing the hoisting plate 2 on both sides of the slot 3.

[0033] In order to improve the supporting strength of the bottom plate 1 and ensure the overall strength of the sling, a rib plate 9 is fixed to the side of the bottom plate 1 facing away from the lifting plate 2 .

[0034] The usage process of this embodiment:

[0035] In this application, since a fixing member is used, the placement of the I-beam 11 is not limited. Figure 3As shown, when the I-beam 11 is placed upright, that is, the upper flange plate is on the top and the lower flange plate is placed on the ground, the present device is used at this time, and the two sets of hoists are respectively placed at the two ends of the upper flange plate of the I-beam 11 to be hoisted, so that the socket is aligned with the T-section of the flange plate of the I-beam 11. Specifically, the slot 3 on the base is aligned with the web of the I-beam 11, and the through groove 4 is located below the flange plate, so that the web of the I-beam 11 is inserted into the slot 3, and the upper flange plate of the I-beam 11 is inserted into the through groove 4. When the end of the I-beam 11 is inserted into the innermost part of the slot, the fixing piece is adjusted so that the fixing plate 6 is against the flange plate of the I-beam 11, and the two sides of the flange plate are respectively against the anti-slip block 7 and the anti-slip convex 8, and the fixing plate 6 presses the flange plate against the bottom plate 1, which increases the stability of the hoisting process of the I-beam 11 and avoids the shaking of the I-beam 11 during the hoisting process, causing the hoisting to be unstable. Then, the crane is used to pull the lifting rope through the lifting hole 10 to lift the I-beam 11. When the I-beam 11 is hoisted in place, the fixing parts can be removed. The present application can also be used when the I-beam 11 is laid flat, that is, laid flat on the ground in an H-shaped manner. Similarly, at this time, two sets of lifting devices can be set at both ends of the web respectively, and the web is directly passed through the through groove 4. Then, the fixing bolts are adjusted so that the fixing plate 6 abuts against the upper surface of the web, so that the lifting devices are fixed at both ends of the web. Then, the crane is used to pull the lifting rope through the lifting hole 10 to lift the I-beam 11. It can be seen that the lifting device of the present application can adapt to various placement forms of the I-beam 11, and through the cooperation of the fastening bolts 5 and the fixing plate 6, the shaking of the I-beam 11 during the lifting process is avoided, thereby increasing the stability of the lifting.

[0036] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
