technical field

A lifting and turning device for special-shaped parts belongs to the technical field of lifting and turning equipment for parts.

Background technique

At present, in large-scale equipment manufacturing enterprises, the transfer of most parts between various processes during processing, and the transfer from the area to be processed to the workbench will involve lifting and turning technology. The current method of hoisting parts mainly uses wire rope slings to fasten the parts, and uses a crane to lift the parts to the processing platform. This method is simple but has a low safety factor, and is suitable for parts with simple structures and easy positioning of lifting points , It is not suitable for hoisting parts with complex structure and heavy weight, and it is difficult to guarantee the safety of workers in the workshop. At the same time, the current parts hoisting method is mainly aimed at the lifting of parts and the control of the position of the lifting point, and the transfer of parts from the area to be processed to the workbench and the transfer between each station during processing will involve zero The change of the processing position of the component needs to consider the turning function of the spreader, which is not involved in the lifting method.

At home and abroad, there are two main methods for lifting and turning the spreader. One is to use the elastic pin as a stopper, the hanging rod is connected with the elastic pin, and the elastic pin is pressed down to take out the hanging rod. The other is to use the lifting ring as a stopper. The block, under the influence of the center of gravity, is stuck and is not concentric with the hanging rod. When the snap ring and the hanging rod are concentric, the hanging rod can be taken out. Although the above two methods refer to the lifting and turning of the spreader, they all have serious drawbacks. They cannot be widely used and have complex structures, are not easy to disassemble, and have low production efficiency and low degree of automation. It is difficult to adapt to the current production situation.
