Description

7710965-0 mounted this season.

When mounting, holes must be drilled in as mentioned the rail, which entails weakening of this with the risk of fatigue. u The location of the devices between the sleepers does this in addition, it is necessary to disassemble them at the track work. Some types of snow removal machines can further not in working position is passed the appliances.

The appliances' lubricant consumption is often like this great that refilling must be done with two to three weeks interval. Because graphite grease is usually used is work is dirty and is perceived by many as a work environmental problems. Fat consumption is difficult to regulate. Therefore the spillage is often large and the contamination of the track edge. ' The present invention has for its object to provide come a way and a facility, which eliminates the above serious inconveniences.

The method according to the invention is characterized in its broadest sense aspect essentially of the rail part being shot in batchwise with lubricant from one at a distance from the rail part, relatively this fixedly mounted, nozzle-shaped bulkhead or dosing unit. 7 By separating the shot or dosing unit from rails, and one or a limited number of lubricants shots are fired, wear on the unit will be limited to a minimum at the same time as effective lubrication of the rail offered without unnecessary waste. No procedures need to be performed rails or rail fastening and track alignment machines can work without the need for the firing or dosing unit race. Nor should it constitute an obstacle to machines. which means that no disassembly need to take place in winter. The pressure in shot or dose the unit is also suitably set so high that even ice and snow may not prevent fat transfer the gate to the rails. When the shot or dosing unit is located on the rail grinder, the lubricant shots are pushed through such obstacle. '7710965-0 The Swedish patent specification 164,390, the Swiss 179,639, the French patents 552,553 and 720,994, U.S. Pat 2,306,013 and the German opening letter 1,405,687 gives examples of the lubrication of existing rail vehicles devices for lubricating the wheel flanges of the vehicle. Above specified specific issue is not relevant for such prior art "passable" lubricants.

Neither of these is intended to deliver lubricant shots of the kind achieved by the method according to the finding.

In practice, it is preferred that lubricant be pushed on just before the train's passage of the relevant rail section. Lubricating- the average shot can be controlled using utilization of between rails existing signal voltage. In practice, this can available so that when a train arrives at that signal distance where the shot or dosing unit is located, it falls electrical voltage between the rails. This affects one valve, which gives the system an impulse to deliver a lubrication means shot to the square of the rail.

Most main tracks in Sweden and also in most other countries normally have a signal voltage between the rails.

If this is not the case, the shot or dosing unit may be breed with electric sensors such as photocell, inductive sensors, timers, etc. These require so little energy that batteries with many months of life can be used. Also solar cells are conceivable.

Propellant resp. lubricants can be supplied via lines the shot or dosing unit from separate filling only storage holders at a distance from this.

In this case, it will be sufficient to fill the containers with lubricant grease resp. propellant at long intervals, for example, twice a year.

The storage containers are then conveniently placed at side of the rails, so that they are easily accessible from one on this mobile service trolley. For the purpose can thus use a tracked trawl equipped with a compressor, Compressed air driven high pressure pump for filling air bottles and a compressed air drive pump for filling lubricating 7710965-o the medium containers from a large container. Such a service tralla should be able to serve a band district with a large number of lubricators. The filling is then performed via quick couplings, so that the operator does not have to get in contact with the grease.

When lubricating curved rail parts for gears on for example marshalling yards can a number of shot or dosing units are connected to a central lubricant container along with the associated pump. This greatly simplifies the lubricant refill.

The invention also relates to a plant for execution of the above procedures, the essential nature of the characteristics are set out in the appended claims.

An embodiment of the invention will be described below. vase with reference to the attached schematic principle sketch in the form of a side view showing a lubrication plant ' of the square to a curved railway track.

A plant for lubricating the part of a fitted railway rails which are subjected to abrasion by a The wheel flanges of a rail vehicle consist of one on one blocks between two rails and at a distance from the outer the inner square square of the bulkhead or dosing unit 6 for lubricating grease and fitted with a square nozzle 7. The shot or dosing unit 6 lacks a mechanism. technical contact with the square and is arranged in portions just before a train or other rail vehicle passes the shell square with lubricant. That in Fig. 1 with dashed lines the wheel 9 shown has a wheel flange 9a.

Next to the rails is another facility associated equipment such as an air tank or pressure air bottle 1, an air control unit 2, and a pump unit 3.

The latter two are connected to a storage container for grease 4, and the pump unit 3 stands like a control unit 5 in connection with the bulkhead or dosing unit 6. The control unit senses via an electrical line 8 a signal voltage which is applied to the current rail part. When a train passes, the voltage drops, which is sensed by the control unit, which thereby giving impulse to dispense a lubricant shot 7710965-0 from the dosing unit 6 towards the square edge of the rail 10. The postponed the amount of lubricant is then spread by those towards the square engaging wheel flanges on the passing rail vehicle.

The air container 1 and the storage container 4 for lubrication greases are provided with connecting nipples ll resp. 12, which are at the right height for easy access from a service trolley or trolley on the rails.

Instead of using a rail applied signal voltage to give impulse to the dosing unit can this controlled in other appropriate ways, e.g. with different types of electrical sensors, such as e.g. photocell or inductive giver. Optionally, a timer can be used, which provides, impulse at appropriate intervals, e.g. a certain number times a day.

The amount of lubricant delivered from the dosing unit is infinitely adjustable by means of an existing one thereon screw knob (not shown).

For lubrication of the gears to a marshalling yard or the like, each of the gears may have one dosing unit 6, 7. Pressure is supplied to each such unit. air and lubricants from centrally located storage containers re 1 resp. 4.

In a further developed embodiment that has large practical advantages, a two- or three-part mouthpiece was used piece on the dosing unit. You can then dose two to three times the amount of lubricant on the sloping square resp. the wheel flange.

An important advantage of the invention is that the dosage the device can be placed on the most suitable in different cases instead of adjacent to a curve or a gear. At single track, it can be placed approximately in the middle of the curve, below that in the case of double tracks a dosing unit is placed at the time to each curve.

It has been found that lubrication of the outer rail square in curve with a radius of less than 600 m entails one wear reduction of approx. 50% for the side wear of the rails.

The reduction in wheel flange wear will probably be the same 'order of magnitude, at least in the case of passenger cars. 7110965-o The significantly longer intervals between service and refilling times and the simplification thereof work which the invention offers entails a considerable sonalin savings. For the same reason, the facility comes to be able to operate a larger number of days per years than previously used equipment.

A functioning rail lubrication system according to The present invention is therefore expected to provide a savings of many millions.
