Movable grounding device for railway wagon

Abstract

The invention discloses a movable grounding device for a railway wagon. The device comprises a trolley assembly, a pull rod assembly, a traction mechanism and a grounding wire; the trolley assembly isplaced on a steel rail and can move along the steel rail, the traction mechanism is installed on the railway wagon, and the two ends of the pull rod assembly are hinged to the trolley assembly and the traction mechanism respectively to form a rigid force transmitting structure with a rotational degree of freedom; the trolley assembly is pulled by the traction mechanism to run, when the railway wagon brakes and decelerates, the trolley assembly is prevented from moving and self-adapts to the relative displacement change between the traction mechanism and the trolley assembly, and the railway wagon carrying power generation equipment is connected with the trolley assembly through the grounding wire, so that the railway wagon and the steel rail form a dynamically-connected grounding circuit.The movable grounding device achieves the purpose of movable grounding of the railway wagon carrying the power generation equipment, the over-voltage of wagon bearings is effectively avoided, the risk of the bearings is damaged, the life safety of workers is ensured, and the requirement of safe grounding when the railway wagon carrying the power generation equipment runs for power supply can be met.

Description

technical field [0001] The invention belongs to the technical field of railway freight car transportation, in particular to a mobile grounding device for railway freight cars. Background technique [0002] At present, with the development of the railway wagon industry, the functional requirements for wagons are increasing. In addition to cargo transportation, it is also necessary to develop a comprehensive railway security vehicle that integrates functions such as emergency rescue, rescue, power generation, water supply, and tunnel flushing. For this type of railway comprehensive support vehicle, the vehicle is generally equipped with independent power generation equipment, and the electricity generated by the generator is strong. The track is dynamically connected to the ground, and the bearings of the existing railway freight cars in our country are not allowed to pass through strong electricity, otherwise the bearings may be damaged and the driving safety will be endanger...
