Description

Technical Field

[0001] The utility model relates to the technical field of slings, in particular to a sling. Background Art

[0002] Steel beams are widely used in decoration projects due to their high strength, light weight, easy processing, and beautiful appearance. At present, when lifting steel beams, lifting ears are generally installed on the upper flange by welding or bolts, and two lifting ears are welded on each beam. The lifting ears are connected by the lifting wire rope of the existing lifting equipment, so that the lifting equipment can lift the steel beam.

[0003] For example, the patent with patent number CN103879886B discloses a special clamp for lifting and fastening steel beams. The clamp is clamped on the flange of the steel beam by bolts passing through the pressure adjustment plate and the horizontal plate body and cooperated with nuts, and a lifting lug with a lifting through hole is provided on the upper end of the vertical plate body. Therefore, deformation of the clamp is avoided during the process of lifting the steel beam by the clamp. However, in actual operation, the clamp is fixed to the steel beam by the cooperation of bolts and nuts, so that the nuts need to be tightened during the installation and removal of the hanger, resulting in cumbersome installation and disassembly operations of the hanger on the steel beam.

Hanging holes 220 are arranged on the four corners of the hanging plate 110, and a clamping groove 200 is arranged on the four sides of the hanging plate 110 and at the center position. The clamping groove 200 is used for the side of the elliptical hole 101 to be clamped in, and fixing devices are arranged on both side surfaces of the hanging plate 110 relatively, and the fixing devices are used to fix the hanging plate 110.

[0025] In this embodiment, the steel beam 100 is in an I-shape, and includes a parallel upper flange 102 and a lower flange 103 and a cross beam 104 disposed therebetween. When the steel beam 100 is hoisted, two elliptical holes 101 are relatively opened on the cross beam 104 of the steel beam 100 according to the hoisting position.

[0026] Among them, by setting the hanging plate 110 and the card slot 200, in actual use, the hanging plate 110 is extended into the corresponding elliptical hole 101, and the hanging plate 110 is rotated so that the side of the elliptical hole 101 is inserted into the corresponding card slot 200, thereby realizing the fixing of the hanging plate 110 on the steel beam 100. At this time, the hanging wire rope 120 is connected to the hanging hole 220, and the hanging wire rope 120 is pulled by the existing lifting equipment to lift the steel beam 100; compared with the existing method of clamping and fixing the clamp on the steel beam by bolts and nuts, the rotation of the hanging plate 110 in the elliptical hole 101 in this embodiment can realize the fixing of the hanging plate 110 on the steel beam 100, and the operation is simple and convenient;

[0027] When the steel beam 100 needs to be lifted vertically, Figure 2 As shown, the hanging plate 110 is extended into the elliptical hole 101 and rotated so that the side of the elliptical hole 101 is clamped into the opposite clamping groove 200, thereby fixing the hanging plate 110 on the steel beam 100. At this time, the hanging wire rope 120 is connected to the hanging holes 220 on both sides of the clamping groove 200 on the same side of the hanging plate 110 and clamped with the side of the elliptical hole 101. At this time, the hanging wire rope 120 can be pulled by the lifting equipment to lift the steel beam 100 vertically;

[0028] When the steel beam 100 needs to be lifted horizontally, Figure 3 As shown, the hanging plate 110 is extended into the elliptical hole 101 and rotated so that the side of the elliptical hole 101 can be clamped into the relative clamping groove 200, thereby fixing the hanging plate 110 on the steel beam 100. At this time, the hanging wire rope 120 is connected to the hanging holes 220 on both sides of the clamping groove 200 on the same side of the hanging plate 110 and not clamped to the side of the elliptical hole 101. At this time, the hanging wire rope 120 can be pulled by the lifting equipment to lift the steel beam 100 horizontally;

[0029] Thus, the steel beam 100 can be lifted in different states through the lifting plate 110, so that the lifting device can lift the steel beam 100 in various ways, making it more applicable;

[0030] The slot 200 is provided so that the side of the elliptical hole 101 can be inserted into the slot 200, that is, the assembly and disassembly of the hanging plate 110 on the steel beam 100 is realized. The side of the opening of the slot 200 forms a rounded corner 210, so that the side of the elliptical hole 101 can be better inserted into the slot 200, so that the hanging plate 110 can be better assembled and disassembled on the steel beam 100.

[0031] Among them, through the setting of the fixing device, when the side of the elliptical hole 101 is inserted into the slot 200, the steel beam 100 is clamped by the fixing device, so that the hanging plate 110 is fixed in the elliptical hole 101, so that during the hoisting process, the hanging plate 110 is not easy to rotate, thereby preventing the side of the elliptical hole 101 from being separated from the slot 200, resulting in failure of hoisting;

[0032] Among them, the maximum diameter of the elliptical hole 101 is greater than the maximum side length of the hanger plate 110, so that the hanger plate 110 can extend into the elliptical hole 101 and rotate, so that the steel beam 100 can be combined with the corresponding slot 200 on the hanger plate 110, thereby realizing the disassembly and assembly of the hanger plate 110 on the steel beam 100 for subsequent lifting.

[0033] In this embodiment, the hanger plate 110 is rectangular, and the fixing device includes fixing parts relatively arranged at both sides of the corresponding slot 200, the fixing parts include a fixing block 201 and a clamping block 202, the fixing block 201 is fixedly connected to the side of the hanger plate 110, one end of the fixing block 201 is provided with a fixing groove 301, one end of the clamping block 202 is hingedly connected to the corresponding fixing groove 301, and the other end of the clamping block 202 is used to abut the steel beam 100 to achieve clamping and fixing of the hanger plate 110.
