AI Technical Summary
During the handling of large-stroke, large-specification plunger cylinders, vertical handling leads to significant damage and makes securing them difficult, while horizontal handling results in uneven stress on the guide ring and a high risk of plunger rod displacement.
Design a fixed fixture for handling plunger cylinders. The cylinder body and plunger rod are connected as one unit by a tight fixing rod and an end positioning flange. Combined with a guide ring and a pressure ring, it ensures that the plunger cylinder is subjected to uniform force when placed horizontally, reducing vibration and displacement.
This technology achieves uniform and integrated force distribution on the plunger cylinder during lifting and handling, reducing the risk of component damage and improving the stability and safety of handling.
