[0002] After completing the driving mission at high speed, the EMU needs to enter the EMU depot or EMU inspection warehouse for preparation and maintenance. Due to the large number of high-speed passenger train manufacturing factories and a wide variety of models, the main EMUs currently in operation include CRH1, CRH2, CRH3, CRH5 and CR standard models, which are further divided into long formations (16 carriages) and short formations (8 carriages). The power supply parameters, power connection socket models, power supply point locations, and the number of socket boxes of various types of high-speed passenger trains are also different, which to a certain extent restricts the convenience of preparation and maintenance of high-speed passenger trains in the inspection warehouse.

[0003] At present, most EMU inspection depots are equipped with EMU ground power supply devices, which are used to provide emergency power to the EMU to be inspected when there is no electricity in the overhead contact network in the depot. However, due to the wide variety of vehicle models, long and short train formations, the positions of power supply points for various types of high-speed passenger trains are also different. During use, the power connection lines need to be paid out and pulled to the corresponding power supply points. During the process of collecting the lines, the power connection lines are prone to be loose and not tightly wound, resulting in the inability to successfully complete the collection. Therefore, there is an urgent need for an automatic collection device for ground power connection lines, which can be used for paying out / collecting the ground power connection lines to meet the collection requirements of the power connection lines.
