Abstract
Method for use in the maintenance of track equipment of the type comprising at least one movable element and a stationary element whose respective contact surfaces come into engagement with one another. The method is characterized by coating the contact surfaces with a given quantity of a composition comprising at least one product with lubrifying properties and a solvent with a high evaporation coefficient.
Claims5
A method for maintaining railway track equipment comprising at least one mobile element and a stationary element, each with a contact surface called upon to bear against that of the other element, this method being of the type comprising a step of depositing on said respective contact surfaces, a given quantity of lubrifying composition, said composition comprising at least one solvent with a high evaporation coefficient such that only an active part of said composition which is spread uniformly on said contact surfaces remains and a wiping effect of said mobile element removing said active part is eliminated, in addition to a body presenting lubrifying properties, said step of depositing being carried out by a device comprising means for pressurizing the lubrifying composition and means for deposition said lubrifying composition substantially at ground level where the track equipment to be maintained is located.
A device for maintaining railway track equipment comprising at least one mobile element and a stationary element, each with a contact surface called upon to bear against that of the other element, said device being of the type comprising means adapted to deposit on the respective contact surfaces a given quantity of a lubrifying composition, said device comprising:
- a reserve 10 of pressurized gas,
- a recipient 11 of the lubrifying composition
- a distributor 12 connecting the reserve 10 with the recipient 11,
- vaporization spray or extrusion means 15 disposed at the lower end of a rigid tube 16 forming a spray nozzle, its length being such that it may be gripped by its upper end by a standing user while the spray is disposed substantially at ground level where the track equipment is located,
- the distributor 12, being directly connected to the vaporization, spray or extrusion means 15 and the recipient 11.
