Description

Technical Field

[0002] With the continuous development of modern industrial technology, planetary gear forgings are increasingly used in heavy machinery, aerospace, automobile manufacturing and other fields. These forgings often have complex structures, large mass, and high precision requirements. Therefore, during the production, transportation and installation process, special lifting equipment is required to ensure its safety and operational efficiency.

[0003] Most of the existing hangers for planetary gear forgings use simple hooks or clamps to meet basic lifting requirements. Due to the irregular sizes of planetary gear forgings, a single clamp can only lift planetary gear forgings of one size, resulting in reduced lifting efficiency. Although the existing hangers can flip the planetary gears during use, they are not equipped with a locking structure and cannot be clamped and limited. Utility Model Content

More specifically, when the planetary wheel forging is hoisted, the driving motor 7 drives the bidirectional screw 8 to rotate, so that the two movable seats 5 slide toward each other along the slide groove 4 opened at the bottom of the crossbeam 1, and the connecting arm 6 arranged at the bottom of the two movable seats 5 drives the arc-shaped clamping frame 11 installed on one side of the fixed plate 10 to rotate the planetary wheel forging, and then rotates the two screws 13 to drive the fixed block 14 arranged at the bottom to move downward, so that the clamping plate 16 connected at one end of the two fixing rods 15 arranged at the bottom presses the surface of the planetary wheel forging, and then the planetary wheel forgings of different sizes and thicknesses can be clamped and fixed, making the hoisting of the planetary wheel forgings more convenient and improving the hoisting efficiency.
