The invention relates to the technical field of rail traffic, and discloses a grounding device of a rail train, which comprises a shell, the shell is movably connected with a first carbon brush and a second carbon brush through a transverse moving sleeve, and the transverse moving sleeve can transversely slide relative to the bottom end of the shell. According to the grounding device of the rail train, when the first carbon brush is worn and used up, the second carbon brush automatically replaces the first carbon brush to work, on one hand, the overall service life of the grounding device is still long, the maintenance and replacement period of workers is prolonged, and the work of maintenance personnel is reduced, on the other hand, due to automatic replacement, the carbon brushes can be replaced after being consumed up, and the cost is reduced, and the utilization rate of the carbon brush is improved; and secondly, one carbon brush is replaced by two carbon brushes, so that the length of the single carbon brush can be designed to be shorter while the reasonable service life is ensured, the length of the whole grounding device is further shortened, the grounding device can be assembled in a narrow space more conveniently, and the replacement and maintenance difficulty is reduced.
本发明涉及轨道交通技术领域,且公开了一种轨道列车的接地装置,包括壳体,所述壳体通过横移套活动连接有第一碳刷和第二碳刷,所述横移套可相对于壳体的底端横向滑动。该轨道列车的接地装置,在第一碳刷磨损用尽时,第二碳刷自动替换第一碳刷工作,一方面,其总体使用寿命仍然较长,延长工作人员维护和更换的周期,减少维护人员的工作,另一方面,由于实现了自动替换,本发明的碳刷可以消耗完才替换,提高了碳刷的利用率,其次,用两个碳刷取代一个碳刷,在保证合理的使用寿命时,本发明的单个碳刷的长度可以设计的更加短小,进而缩短了整个接地装置的长度,可以更加方便装配与狭小空间,降低更换和维护难度。
