Description
Technical field
The utility model is related to transportation machinery fields, relate in particular to a kind of railcar shaft end ground connection dress
It puts.
Background technology
Axle head grounding device is mounted on metro vehicle bogie shaft end, in railcar operational process, plays and is grounded back
The effect of stream.
Existing railcar is unsatisfactory for degree of protection IP67, IP67 with axle head grounding device and refers to protection safety rank.
IP is the abbreviation of Ingress Protection Rating (or International Protection code), it is defined
Protective capacities of one interface to liquid and solid particle.IP is followed by 2 bit digitals, and the 1st is solid-state degree of protection, model
It is 0-6 to enclose, and is represented respectively to the protection from bulky grain foreign matter to dust；2nd is liquid degree of protection, and range is 0-8, respectively
It represents to the protection in the case of dripping to bottom pressure from vertical water.Number is bigger, and its protective capacities of expression is stronger.Second after IP
Digital waterproofing grade, 0 grade is unshielded, and 7 grades are to prevent impregnating in short-term, i.e., under normal temperature and pressure, when shell is temporarily immersed in 1M depths
It will not result in adverse effect in water.
Utility model content
The utility model provides a kind of railcar axle head grounding device of Optimal improvements, overcomes existing earthing or grounding means
The defects of being unsatisfactory for degree of protection IP67 is avoided that parts corrosion occur in earthing or grounding means and truck journal box assembling inner inlet
And phenomena such as bearing failure.
Technical solution provided by the utility model is：A kind of railcar axle head grounding device, including end cap, contact
Disk, insulating support, brush holder, the assembling of pressure cover board, carbon brush component, O-shaped rubber seal II, O-shaped rubber seal I, cable lock
Head and O-shaped rubber seal III；The pressure cover board assembling is connected with brush holder, and connection mode is is bolted；The carbon brush group
Part shares 3, and carbon brush component is arranged in brush holder and is connected with brush holder, and connection mode is is bolted；3 carbon brush components
Offer pressure is assembled by pressure cover board to contact with contact disc；The O-shaped rubber seal I is installed on brush holder, and O-shaped rubber is close
Seal II and O-shaped rubber seal III is respectively arranged in the upper and lower surface of insulating support.
Preferably, the end cap is arranged below insulating support, positioned at entire axle head grounding device bottom.
Preferably, the cable lock is arranged on brush holder, positioned at the side of axle head grounding device.
Operation principle：Earthing or grounding means is needed to seal by three faying faces, i.e. the assembling of pressure cover board and brush holder composition surface, brush holder
With insulating support composition surface, insulating support and end cap composition surface, traditional earthing or grounding means is using non-asbestos seal paper as pressure cover
Plate assembles the sealing material with brush holder composition surface, but sealed paper is water wetted material in itself, and compressibility is poor, and by pressure cover board group
Dress and the influence of brush holder precision, the requirement for causing this sealing structure that can not meet degree of protection IP67, the utility model will seal
Material is changed to O-shaped rubber seal by sealed paper, and increases gasket.During work, current path flows into brush holder, brush holder for cable
Carbon brush component is flowed into, carbon brush component flows into contact disc, and contact disc flows into axle, and then flows into wheel and rail, realizes ground connection
The effect of reflux is played the role of preventing bogie bearing galvanic corrosion, improves vehicle reliability of operation.
Advantageous effect：A kind of railcar axle head grounding device of the utility model, is avoided that earthing or grounding means and bogie
There is phenomena such as parts corrosion and bearing failure in axle box assembling inner inlet, meets the requirement of degree of protection IP67, improves vehicle
Reliability of operation.
Description of the drawings
Attached drawing described herein is to be used to provide a further understanding of the present invention, and forms one of the application
Point, but do not form the restriction to the utility model.
