AI Technical Summary

Technical Problem

The existing Z1 wheelset repair and replacement operation is time-consuming, inefficient, requires high manual participation, and has high labor costs. In addition, there is a lack of supporting lifting equipment, resulting in it taking more than 20 minutes to replace a wheelset, which cannot meet the daily planned workload.

Method used

An operating device is designed, which includes a base, a circular turntable, columns, a crossbeam and a matching action execution mechanical mechanism. By reducing the replacement space between the new and old wheelsets, the motion trajectory of the wheelset replacement is optimized to achieve mechanical automation operation.

Benefits of technology

It improves the efficiency of wheelset replacement, significantly reduces manpower consumption, shortens operation time to ≤10 minutes, reduces manual participation, and meets the daily planned operation volume requirements.

Abstract

The invention provides an operation device for replacing a wheel set. The operation device comprises a base, an annular rotating disc, a stand column and a cross beam. Wherein the base is used for being positioned on a railway track; the annular rotating disc is mounted on the base, and the annular rotating disc can rotate on the base and can be positioned at any position in the rotating direction; two groups of brackets are fixedly arranged on the annular turntable and are used for supporting an old wheel set or a new wheel set; the stand column is fixedly installed on the base and located on the annular inner side of the annular rotary disc. The cross beam is rotationally installed at the top end of the stand column, and a rotating mechanism is connected between the cross beam and the stand column. The invention provides a method for replacing the wheel set. The method is realized by adopting the operation device for replacing the wheel set. The wheel set replacing device has the beneficial effects that the efficiency of replacing the wheel set in the servicing line can be improved, and manpower consumption can be remarkably reduced.
