AI Technical Summary
The existing grinding wheel installation structure of railway line grinding vehicles is cumbersome to disassemble, especially the bolts located under the vehicle body, which are difficult to remove, affecting maintenance efficiency.
The mounting sleeve, which adopts a slide rail and insert rod structure, combined with a lifting sleeve and threaded column design, allows the insert rod to be inserted into the grinding wheel mounting hole by rotating the lifting sleeve, thus achieving quick fixing and disassembly of the grinding wheel.
It simplifies the installation and removal process of the grinding wheel, improving the convenience of operation and maintenance efficiency.
