AI Technical Summary

Technical Problem

In the ground charging system of new energy shunting locomotives, the charging cable is prone to friction with the ballast around the railway station track during frequent dragging, which leads to wear on the cable sheath, cracking of the insulation layer and damage to the internal core, posing safety hazards and shortening the equipment life.

Method used

A cable support structure including a hollow cable support rod, a winding wheel, and a servo motor was designed to enable automatic cable feeding and reeling. Combined with an air pump, air guide chamber, and air duct structure, a bidirectional airflow is formed for heat dissipation and dust removal, preventing the cable from dragging directly on the ground.

Benefits of technology

It effectively prevents cable sheath wear and insulation layer cracking, improves safety and equipment life, ensures charging efficiency and delays insulation layer aging.

Abstract

The application discloses a ground charging system for a new energy shunting locomotive and relates to the technical field of new energy shunting locomotives.The technical points of the ground charging system include a charging pile body, charging cables symmetrically and fixedly installed on the side of the charging pile body, and a hollow wire supporting rod.The end of the charging cable away from the charging pile body is fixedly installed with a charging gun head.The outer side of the charging pile body is provided with a wire supporting structure.The hollow wire supporting rod wire supporting structure includes two hollow wire supporting rods rotatably connected to the two sides of the charging pile body.The wire supporting structure is arranged to realize the winding and unwinding of the charging cable, avoid the direct dragging of the cable on the ground, reduce the friction with the ballast, effectively prevent the abrasion of the outer sheath of the cable, form a two-way airflow by using the air pump, the air guide cavity, the ring cylinder and the gun head cooling channel and other airway structures, take away the heat of the cable and the gun head, blow off the surface dust, guarantee the charging efficiency, delay the aging of the insulation layer, and improve the safety and the service life of the equipment.
