Description

Technical Field

[0001] This utility model belongs to the technical field of lifting equipment, specifically relating to a wear-resistant and cut-resistant lifting sling. Background Technology

[0002] Conventional lifting slings (synthetic fiber lifting slings) are generally made of high-strength polyester filaments, which have many advantages such as high strength, wear resistance, oxidation resistance, and UV resistance. At the same time, they are soft, non-conductive, and non-corrosive (harmless to the human body) and are widely used in various fields.

[0003] Over long-term use, lifting slings will suffer surface damage due to excessive friction. If a replaceable protective strap can be installed on the surface, its service life can be increased. Utility Model Content

[0004] The present invention aims to solve the technical problems existing in the prior art and provide a wear-resistant and cut-resistant lifting sling.

[0005] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: a wear-resistant and cut-resistant lifting sling, including a sling, a protrusion provided in the middle of the sling, equipment side straps provided on both the left and right sides of the sling, a sling strap opening provided on the side of the equipment side strap away from the sling, thickened side edges provided on both sides of the equipment side strap, a reinforcing slide provided at the top and bottom of each thickened side edge, a semi-circular groove provided on the surface of the reinforcing slide, a sliding buckle fitted onto the side surface of the thickened side edge, the sliding buckle being slidably disposed between two reinforcing slides on the same side, a transverse pressure band laid on the surface of the equipment side strap being connected to the top of two symmetrical sliding buckles, and cut-resistant kits fitted onto the top and bottom of the sling respectively.

[0006] Preferably, the protrusion is high in the middle and low on both sides, and the protrusion is filled with thickened rubber.

[0007] Preferably, the opening of the suspender strap is stitched with a thickened layer.

[0008] Preferably, the sliding buckle includes a U-shaped component, a semi-circular locking head, and a threaded seat. The U-shaped component is slidably disposed on two reinforced sliding surfaces on the same side, and a semi-circular locking head that slides against the semi-circular sliding groove is provided on the U-shaped component at the connection between the two. An inner sliding groove is formed on the inner side of the U-shaped component corresponding to the semi-circular locking head. A threaded seat is fixedly inserted into the top of the U-shaped component downwards, and a screw is threadedly connected to the surface of the threaded seat.

[0009] Preferably, the left and right sides of the transverse pressure band are provided with through slots corresponding to the screws, and the bottom of the transverse pressure band is provided with multiple pressure teeth.

[0010] Preferably, the cut-resistant kit includes a protective belt, with side ears integrally provided on both the left and right sides of the protective belt. Each side ear has a positioning hole on both sides that fits onto the threaded surface, and a metal ring for protection is provided on the surface of the positioning hole.

[0011] The beneficial effects of this utility model are as follows: By providing thickened side edges on both sides of the equipment side belt, it has a better snap-in effect when installing the reinforced slide, and can better fix the reinforced slide onto the thickened side edges. At the same time, sliding buckles are slidably set on the thickened side edges, and transverse pressure bands are connected to the top and bottom of the sliding buckles on both sides. With the help of screws and pressure teeth, the protective belt is installed on the surface of the sling. It is easy to replace and still has the same protective effect. Attached Figure Description

[0017] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0018] Example: A wear-resistant and cut-resistant lifting sling, such as Figures 1-4As shown, the device includes a sling 11, with a protrusion 12 in the middle, the protrusion 12 being higher in the middle and lower on both sides. The protrusion 12 is filled with thickened rubber 121. Equipment side straps 13 are provided on both sides of the sling 11. A strap opening 14 is provided on the side of the equipment side strap 13 away from the sling 11, and a thickened layer 141 is sewn into the strap opening 14. Thickened side edges 131 are provided on both sides of the equipment side straps 13. A reinforced slide 2 is provided at the top and bottom of each thickened side edge 131. A semi-circular groove 21 is formed on the surface of the reinforced slide 2. The connection between the fixed slide 2 and the equipment side belt 13 is provided with locking teeth for interlocking, and is pressed and fixed to the thickened side 131 by a pressing device. Multiple small slots are opened on both sides of the reinforced slide 2 to further reinforce the tightness of the connection between the reinforced slide 2 and the equipment side belt 13 by stitching. The side surface of the thickened side 131 is fitted with a sliding buckle 3, which is slidably set between two reinforced slides 2 on the same side. The top of the two symmetrical sliding buckles 3 is connected to a transverse pressure strip 35 laid on the surface of the equipment side belt 13. The top and bottom of the sling 11 are respectively fitted with anti-cut kits.

[0019] The sliding buckle 3 includes a U-shaped part 31, a semi-circular locking head 32, and a threaded seat 33. The U-shaped part 31 is slidably mounted on the surfaces of two reinforced slides 2 on the same side, and the U-shaped part 31 at the connection point of the two is provided with a semi-circular locking head 32 that slides against the semi-circular slide groove 21. The inner side of the U-shaped part 31 corresponding to the inner side of the semi-circular locking head 32 forms an inner slide groove 34. The top of the U-shaped part 31 is fixedly inserted with a threaded seat 33, and the surface of the threaded seat 33 is threaded with a screw 36. The left and right sides of the pressure band are provided with through slot holes 351 corresponding to the screws 36. The bottom of the transverse pressure band 35 is provided with multiple pressure teeth 352. The anti-cut kit includes a protective band 41. The left and right sides of the protective band 41 are integrally provided with side ears 42. The two sides of each side ear 42 are provided with positioning holes 43 that fit onto the threaded surface. The surface of the positioning hole 43 is provided with a protective metal ring. The metal ring is used to prevent the protective band 41 from tearing when connected with the screw 36.

[0020] The principle of this utility model is as follows: After removing the screw 36, the transverse pressure band 35 is also removed. Then, the protective band 41 is installed at the positions of the four screws 36 on both sides, so that the positioning holes 43 on the side ears 42 of the protective band 41 are placed in accordance with the positions of the screws 36. Then, the transverse pressure band 35 is inserted, so that the multiple pressure teeth 352 at the bottom press against the side ears 42. At the same time, the through slot hole 351 at the top of the transverse pressure band 35 is pressed into the threaded seat 33 in the lower slide buckle 3 for threaded connection. Similarly, the protective band 41 is installed at the bottom of the sling 11. The sling 11 is installed on the surface of the slide buckle 3, and the slide buckle 3 is a U-shaped part 31 that is snapped between the two upper and lower reinforced slides 2. When the sling 11 is bent and stretched, the protective band 41 has a better tension effect.

[0021] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and many variations are possible. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
