Definitions
- the present invention relates to the field of technology comprising means which are used for the lubrication of metal members for the purpose of protecting them against corrosion and prolonging their serviceability.
- the device according to the invention concerns the specific sector of lubrication of the plurality of elements provided with a projecting part which are arranged at regular intervals along a linear member for which they serve as anchoring, connection and/or jointing means.
- a typical case in which the abovementioned device can be advantageously used is that of lubrication of the fixing means, such as bolts with or without ring nuts, washers or other small parts, which serve for fixing railway tracks on their support sleepers.
- such bolts are arranged, with their heads projecting upwards, at regular intervals along the entire length of the tracks and are fixed on both bearing sides of each of the two parallel elements (the rails) which form a track. It is periodically necessary to carry out lubrication of the parts of said bolts, such as the head and the threaded shaft, to avoid oxidation reducing the reliability of their fixing with the passing of time and rendering their removal by means of unscrewing problematic and extremely difficult.
- the abovementioned lubrication is performed manually by an operative who, while walking along a track, uses a brush to take a lubricating fluid from a bucket containing it and apply it to said bolts.
- the inventor of the present invention has designed a device which, mounted on a rail, can run along the latter, pushed by an operative or by other means, and automatically effect the lubrication of all the fixing bolts that it encounters as it travels along.
- the device 1 comprises primarily a body 2, also constituting its bearing structure, which contains lubricating fluid 18 in a suitable tank 17 in its interior (see Figure 3).
- Said body is supported by bearing members consisting of two small wheels 3, 4 made of insulating material, although they can also consist of one or more sliding blocks (not shown).
- Said bearing members have a groove 14 which, in the case shown, extends over the entire external contact surface of the small wheels 3, 4 and has a shape which is complementary to that of the rail 8, as can be seen in Figure 2.
- the ends of two tubes 5, 6, which are preferably each provided with a unidirectional valve 21 which prevents the fluid flowing back from the tubes 5, 6 to the tank 17, extend down into said tank 17 containing the lubricating fluid 18.
- Said tubes 5, 6 are bent in a U shape and their other end is terminated by an ejection nozzle 5u, 6u which is directed downwards, that is to say towards the fixing means 8 to be lubricated, with an appropriate inclination ⁇ in relation to the vertical, the purposes of which will be defined in the course of the description.
- Each of said two tubes 5, 6 forms part, together with said tank 17, of a hydraulic system 11 provided with a mechanical pump 12 of the positive-displacement type, the pressure piston 19 of which is connected to a striker member, a simple mechanical arm 13 in this case, which is articulated on the body 2 and is directed downwards, that is to say towards the bearing plane of the rail 9.
- Said arm 13 is shaped and dimensioned in such a manner that, during the translation of the device 1 along a rail 9, its free end 131 strikes against those parts 8s of the fixing means 8 of the rail 9 which project upwards in relation to said bearing plane ⁇ , rotating (see arrow A) on account of the impact so as to overcome the obstacle without causing the translation movement of the device 1 to stop or to decelerate appreciably.
- a counter-spring 15 fixed to the other end of the arm 13 then returns it to its starting position by making it counter-rotate (see arrow B).
- the pressure piston 19 of the abovementioned pump 12 takes into a chamber 20 a predetermined quantity of lubricating fluid 18 from the tank 17 by means of the respective tube 5 and then, on account of the counter-rotation B, conveys it to the associated nozzle 5n in which the tube 5 terminates towards the outside.
- the hydraulic systems can be dimensioned in such a manner that the lubricating fluid 18, leaving the nozzles 5u, 6u at a predetermined pressure, is atomized to the appropriate degree by the latter, increasing its capacity to penetrate even the narrow gaps of the fixing means which is usually a captive bolt 8 as represented in the drawings.
- the pumping and ejection operation takes place with a certain advance in relation to the moment at which the ejection nozzle 5u, 6u passes through the vertical of the fixing means 8.
- the inventor has consequently made provision for the nozzles 5u, 6u, or the terminal length of the tubes 5, 6 connected thereto, to be orientated so as to achieve a predetermined inclination ⁇ in relation to the vertical, as can be seen in Fig. 1, which makes it possible to direct the jet towards the point where the fixing means 8 to be lubricated is situated at the moment when ejection of the fluid takes place.
- the device 1 In order to operate, the device 1 according to the invention must, as mentioned, be made to move on its bearing members 3, 4 along the rail 9, the fixing means 8 of which are to be lubricated. To this end, the inventor has made provision to equip the device 1 with handlebars 7 which can be held and manoeuvred with ease by an operative following the course of the rail 9 on foot.
- the device can be made to move by a railway carriage or by a locomotive connected to it by an appropriate frame (not shown because it is easy to imagine and to put into effect), or can generate its own motion by means of a DC electric motor powered by batteries, which is secured with these on the body 2 of the device 1. (This case is not shown either for reasons similar to those in the preceding case.)
- the device according to the invention affords an effective means of easily carrying out the periodic lubrication of sections of railway line, reducing the effort and the danger involved for the operatives performing the work, appreciably increasing the functionality and the reliability of the result, and moreover allowing a considerable saving on the quantity of lubricating fluid used.
