AI Technical Summary

Technical Problem

In the existing technology, the installation and disassembly of hoses and quick couplings in the traction converter cooling system are laborious, time-consuming, easily damaged, inefficient, and space-constrained. In particular, it is difficult to install and disassemble large-sized hose liner couplings with large interference fits.

Method used

A quick connector replacement device was designed, including a hose end locking module, a connector end locking module, and a lifting actuator. The lifting actuator drives the hose to rise and fall relative to the connector, which, together with the locking module, enables the quick installation and removal of the hose and the quick connector.

Benefits of technology

It improves the efficiency of installing and removing hoses and quick couplings, avoids hose deformation and damage, achieves standardized operation, has a compact structure and is easy to carry, and provides convenience for traction converter cooling systems.
