Description

Technical Field

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

[0002] A hoist is a rigid object-grabbing device used for lifting and hoisting operations, which can directly lift objects. When the motor stator is placed upright, it is a hollow cylindrical shape and is relatively heavy. It cannot be moved by manpower and other tools such as binding belts and hooks cannot be used. Therefore, an internal support hoist is needed to be inserted into the inner cavity of the motor stator core, so that the internal support hoist can be expanded upward to support the inner wall of the motor stator core and lift the motor stator, so as to realize the hoisting operations such as motor stator handling, shrink fitting, shell embedding, painting, and upper and lower production lines.

[0003] Now we search for a Chinese patent for an internal support type sling, publication number CN 221191282 U. This utility model relates to an internal support type sling, including a sling body, a lifting ring is arranged at the upper end of the sling body, a lifting rod is connected to the lower end of the lifting ring, a pull plate is sleeved on the lifting rod, and unlocking finger rings are arranged on both sides of the upper end of the pulling plate. This sling has a simple and ingenious structural design, is easy to use, and can improve work efficiency. When in use, two fingers pull the unlocking finger ring to shrink the sling, and after shrinking, put it into the workpiece. The three support arms of the sling will automatically pop open and contact the inner wall of the workpiece by their own gravity. The crane pulls the lifting ring. During the lifting process, the force is converted into supporting force and friction force, and the tighter the support is, the stator core of the motor can be lifted. After the lifting is completed and settled, two fingers pull the unlocking finger ring to shrink the sling, and the sling can be taken out.

[0004] In actual use, the motor stators have different specifications and different sizes of internal hollow cylinders. If the motor stator is larger and the internal cylinder is higher, while the polyurethane rubber in contact with its inner wall is of fixed size, the downward pulling force it bears is too large, and there are still certain safety hazards. Therefore, it is necessary to provide an improved internal support hanger to solve the above problem. Utility Model Content
