Description

Technical Field

[0001] This utility model belongs to the field of hoisting equipment technology, specifically relating to a high-strength multi-eye flat sling. Background Technology

[0002] Flat slings are lifting and hoisting tools made primarily of synthetic fibers, widely used in ports, docks, chemical plants, steel mills, and machinery installation. They are woven and sewn from materials such as polyester, polypropylene, and nylon, and are lightweight, corrosion-resistant, and do not damage the surface of the object being lifted. They offer a safety factor of 4-8 times and comply with the JB / T8521-1997 standard.

[0003] Lifting slings are generally used to lift goods by tying one end of the goods to the crane and the other end to the crane, or by using two ends to support the crane and passing the goods across the middle. However, the lifting height of the slings cannot be adjusted, and the goods need to be more stable when tying them horizontally, so improvements are needed. Utility Model Content

[0004] The present invention aims to solve the technical problems existing in the prior art and provide a high-strength multi-eye flat sling.

[0005] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: a high-strength multi-eye flat sling, including a flat sling body, characterized in that: lifting lugs are respectively provided on both sides of the flat sling body, and a thickened strip is provided below the lifting lugs on both sides of the flat sling body, with the thickened strip having a raised middle on both sides to form an insertion interface, a metal ring being inserted into the insertion interface, an auxiliary lifting lug being sleeved on the surface of the metal ring, and a top limiting structure being provided in the middle section of the flat sling body for lateral sliding.

[0006] Preferably, the flat sling body suspended at both ends has center-of-gravity straps on both the upper and lower sides of the center-of-gravity point.

[0007] Preferably, multiple symmetrical thickened blocks are provided on the left and right sides of the flat suspender body, and the symmetrical thickened blocks are inserted into the interior of the flat suspender body and extend 2cm above the surface of the flat suspender body.

[0008] Preferably, the top limiting structure includes a first sliding buckle and a second sliding buckle. The first sliding buckle and the second sliding buckle are respectively interlocked on the surface of the flat suspender body. An opening is provided on one side of the first sliding buckle. A locking buckle is rotatably provided on the first sliding buckle corresponding to the buckle part. One end of the locking buckle is rotatably connected to the first sliding buckle, and the other end is locked to the first sliding buckle.

[0009] Preferably, the first and second sliding buckles are provided with plug-in buckles on their opposite sides, and the plug-in buckle surfaces have multiple openings, with a pressure strip wrapped around the plug-in interfaces of the two plug-in buckles.

[0010] The beneficial effects of this utility model are as follows: By setting thickened straps below the lifting lugs on both sides, the thickened straps are fixed to the surface of the flat sling body by sewing. At the same time, the insertion interface left during the sewing on both sides can be fitted with metal rings. The lifting height of the entire flat sling body can be changed by using the metal rings to fit the auxiliary lifting lugs. At the same time, two auxiliary lifting lugs are set on each side to reduce the stress on a single auxiliary lifting lug. In addition, by setting top limiting structures on both sides of the surface of the flat sling body, the structure can slide on the surface of the flat sling body through the first and second sliding buckles on both sides. At the same time, the pressure strip is fitted between the first and second sliding buckles to press down on the surface of the material for lifting, making the lifting of goods more stable.

Detailed Implementation

[0014] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0015] Example: A high-strength multi-eye flat sling, such as Figures 1-2As shown, the device includes a flat suspender body 1, characterized in that: two sides of the flat suspender body 1 are respectively provided with lugs 11, and a thickened strap 31 is provided below the lugs 11 on both sides of the flat suspender body 1. The thickened strap 31 is made of woven fabric and is fixed to the flat suspender body 1 by sewing. The two sides of the thickened strap 31 are respectively raised in the middle to form an insertion interface 32. A metal ring 33 is inserted into the insertion interface 32. The metal ring 33 can be either integral or with a slit in the middle. For integral metal rings, it is inserted into the thickened strap 31 before the insertion interface 32 is formed and sewn. For slit metal rings, it is inserted into the thickened strap 31 through the slit. An auxiliary lug 3411 is sleeved on the surface of the metal ring 33. When the auxiliary lug 3411 is used with the integral metal ring 33, it is bound to the metal ring 33 before sewing. For slit metal rings, it is inserted through the slit. A top limiting structure 2 is provided in the middle section of the flat suspender body 1 for lateral sliding connection.

[0016] The flat sling body 1, which is suspended at both ends, has center-of-gravity straps 13 on both the upper and lower sides of the center of gravity. These straps are used to quickly identify the center of gravity before lifting, so that the goods will not slip during subsequent lifting. Multiple symmetrical thickened blocks 12 are provided on the left and right sides of the flat sling body 1. The symmetrical thickened blocks 12 are inserted into the interior of the flat sling body 1 and are 2cm higher than the surface of the flat sling body 1.
