Description

Technical Field

[0001] The utility model belongs to the technical field of hoisting tools, and in particular relates to a flame retardant and fireproof hoisting tool. Background Art

[0002] In the process of mechanical manufacturing and object handling, lifting and handling methods are often used. During the lifting process, rigging such as lifting belts are needed. As a flat sling made of high-strength fiber, lifting belts are light, durable, easy to operate, and can effectively protect objects and lifting equipment. They are mainly used for lifting and carrying various heavy objects.

[0003] At present, in special lifting environments such as metal casting, the lifting environment temperature is high, and high-temperature debris or sparks may be generated easily, so flame-retardant and fireproof lifting belts are used. Their unique flame-retardant and fireproof structure can ensure stability and safety under extreme conditions, and effectively prevent the occurrence and spread of fire. However, in the process of lifting objects with existing lifting belts, due to the lack of limiting structure, objects are prone to slipping from the lifting belts, and the lifting safety factor is low. For this reason, the present application proposes a flame-retardant and fireproof lifting belt. Utility Model Content

The pulling tube 6 is also provided with a positioning member 9 for positioning the ring 5 on the sling body 1. Through this structural mode, when lifting objects, the sling body 1 passes through the bottom of the object, the rings 2 at both ends of the sling body 1 are hung upward on the lifting equipment, and then the hooks 7 on the two pulling tubes 6 are hooked on the top of the object, and the pair of pulling tubes 6 are pushed to continue to approach the object until the sling body 1 binds the object tightly, and the positioning member 9 is used to position the ring 5 on the sling body 1. As a result, the object can be in a tied state during the lifting process using the sling body 1, which can effectively prevent the object from slipping and improve the lifting safety factor.

[0028] The locating member 9 is provided with a stopper 10 which is movably embedded in the pull tube 6. A locating pin 11 is fixed on one side of the stopper 10 facing the collar 5. The locating pin 11 passes through the collar 5. A locating hole 4 is provided on the sling body 1 to allow the locating pin 11 to pass through. The locating member 9 also includes a tightening spring 12 arranged in the pull tube 6. The tightening spring 12 is located on the side of the stopper 10 away from the locating pin 11.
