Description

Technical Field

[0001] This utility model relates to the field of lifting sling technology, and in particular to a special lifting sling. Background Technology

[0002] In lifting operations, slings are crucial lifting tools, bearing the heavy responsibility of lifting heavy objects from one place to another. With the development of modern industry, the requirements for the functionality, safety, and adaptability of slings are becoming increasingly stringent. Traditional slings often have simple structures and limited functions, making it difficult to meet the complex and ever-changing needs of lifting operations.

[0003] On the one hand, traditional slings are typically simple in height adjustment, lacking flexibility and precision. This necessitates frequent changes of slings or adjustments to the height of lifting equipment when hoisting objects at different heights, increasing not only operational difficulty and labor intensity but also reducing the efficiency of hoisting operations.

[0004] On the other hand, traditional slings also have shortcomings in clamping and supporting objects. The clamping force is not stable enough, which can easily cause objects to slip or sway during hoisting, posing a safety hazard. At the same time, the support surface is usually relatively fixed, making it difficult to adapt to objects of different shapes and sizes, thus limiting the versatility and practicality of slings. Utility Model Content

[0005] The purpose of this utility model is to provide a special lifting sling to solve the problems mentioned in the background art and facilitate its promotion.

[0006] A special lifting sling includes a horizontal plate, an adjustment assembly below the horizontal plate, a limiting assembly on the adjustment assembly, a telescopic assembly below the adjustment assembly, a clamping assembly on the inner wall of the telescopic assembly, a supporting assembly below the telescopic assembly, and a lifting assembly on the outer wall of the horizontal plate.

[0007] The adjustment assembly includes two vertical plates, a first vertical plate and a second vertical plate, symmetrically arranged below the horizontal plate. An adjustment rod is rotatably mounted on the inner wall of the second vertical plate. An adjustment knob is fixedly mounted on the end of the adjustment rod away from the inner wall of the second vertical plate through the first vertical plate. The adjustment rod has an adjustment thread 1 and an adjustment thread 2. A lead screw and nut pair are threadedly connected to the adjustment thread 1 and the adjustment thread 2. A strip-shaped through hole is provided on the horizontal plate. A guide rod is provided on the lead screw and nut pair. A guide limit plate is fixedly mounted on the end of the guide rod away from the lead screw and nut pair through the strip-shaped through hole.

[0008] Furthermore, the telescopic assembly includes a telescopic bushing fixedly disposed below the lead screw nut pair, a telescopic rod inserted inside the telescopic bushing, a plurality of evenly arranged telescopic adjustment holes on the telescopic rod, a limiting bolt inserted on the telescopic bushing, and a limiting nut threadedly connected to the telescopic bushing through the telescopic bushing.

[0009] Furthermore, the clamping assembly includes a clamping fixing rod fixedly disposed on the inner wall of the telescopic bushing, and a clamping block is fixedly disposed at one end of the clamping fixing rod away from the inner wall of the telescopic bushing.

[0010] Furthermore, the support assembly includes a support groove 1 and a support groove 2 symmetrically and pairedly arranged on the telescopic rod. A support plate is inserted into the support groove 1 and the support groove 2. The support plate has a plurality of evenly arranged support threaded holes. Support fixing bolts are threadedly connected to the support groove 1 and the support groove 2. The support fixing bolts pass through the support groove 1 and the support groove 2 and are threadedly connected to the support threaded holes.

[0011] Furthermore, the hoisting assembly includes hoisting chain one and hoisting chain two symmetrically arranged on the outer wall of the horizontal plate, and the end of hoisting chain one and hoisting chain two away from the horizontal plate is provided with a hoisting ring.

[0012] Furthermore, the limiting assembly includes a limiting connecting plate disposed on the adjusting rod and a plurality of evenly arranged limiting holes opened on the outer wall of the upright plate. A limiting pin is inserted into the limiting connecting plate, one end of the limiting pin is inserted into the limiting hole, and the end of the limiting pin away from the limiting hole passes through the adjusting knob and is fixedly provided with a pull plate. A limiting spring is provided between the adjusting knob and the limiting connecting plate, and the limiting spring is sleeved on the limiting pin.

[0013] As an improvement, the beneficial effects of this utility model are as follows:

[0014] This utility model discloses a special lifting sling, which allows for flexible length adjustment through structures such as the telescopic bushing, telescopic rod, and limiting bolts in the telescopic assembly. This design not only meets the lifting needs of objects of different sizes but also improves the sling's versatility and practicality. The clamping fixing rod and clamping block in the clamping assembly firmly hold the object to be lifted, preventing slippage or swaying during lifting and ensuring the safety and stability of the lifting operation. The support groove, support plate, and support fixing bolts in the support assembly provide a solid support surface for the object, further enhancing the sling's load-bearing capacity and stability. This design enables the sling to maintain excellent stability and reliability even when lifting heavy or irregularly shaped objects. Attached Figure Description
