Definitions

  • the present invention relates to a device for the application and/or removal of connecting fasteners (so-called e-clips or fast-clips) for connecting a rail to a tie of a railway track.
  • connecting fasteners so-called e-clips or fast-clips
  • the insertion (also called application) of the connecting fasteners aims to fix the rail to the underlying ties, while the extraction (or removal) of the fasteners releases the connection between the rail and the tie.
  • Connecting fasteners are usually applied on two opposite sides of the rail base and have an anchoring portion destined for insertion in an anchoring seat, the so-called joint of the tie and a pressure portion destined to be inserted over the rail base so that with the connecting fastener applied (or inserted) it engages the tie and the rail and keeps them connected and pressed against each other.
  • the joints of the ties and the connecting fasteners are configured for insertion and extraction of the fastener in a direction substantially horizontal and perpendicular to the longitudinal direction of the rail.
  • the joints of the ties and the connecting fasteners are configured for insertion and extraction of the fastener in a direction substantially horizontal and parallel to the longitudinal direction of the rail.
  • Machines for the application or removal of connecting fasteners from rails and ties are known from WO-A-2006/031168 , hereinafter for brevity called "application machines", which may have large dimensions if made for the laying of new railway lines, or small in size and weight, and more easily transportable if designed for the maintenance of sections of existing rail.
  • the application machines of the prior art typically comprise a frame which can rest on the rail by means of support rollers, a thrust member mounted on the frame so as to shift in relation to the frame in a direction of insertion and/or extraction and suitable to engage the connecting fastener, at least one oleo-dynamic actuator mounted on the frame and connected to the thrust member to move the thrust member in the direction of insertion and/or extraction to apply or remove the connecting fastener from the rail.
  • the oleo-dynamic actuator is driven by an oleo-dynamic pump connected to an internal combustion engine.
  • the engine once started, always works at the maximum number of revolutions needed for the proper functioning of the pump in all operating phases.
  • the pressurising and depressurising of the oleo-dynamic actuator does not take place by switching on or off the internal combustion engine or the oleo-dynamic pump, but by switching valves that permit or interrupt access to the oil permanently pumped and pressurised by the oleo-dynamic actuator.
  • the duration of operation of the engine is thus determined by the capacity of the fuel tank, since switching on or off the engine during the application and removal phases of the fasteners is not feasible as considered incompatible with the type, sequence and timing of this type of work.
  • a further disadvantage of the application machines of the prior art consists of the poor handling and practicality during transport and use due to the distribution of the weight and dimensions in relation to the gripping handles, of the lack of adaptability of the machine to the stature and strength of the operator and of the fact that the application machine does not actively contribute to the correct movement and positioning of the rail to the tie before the insertion of the connecting fastener.
  • the purpose of the present invention is therefore to make available an application machine for the application and/or removal of connecting fasteners (so-called clips, e-clips or fast-clips) for connecting a rail to a tie of a railway track, having characteristics such as to overcome at least some of the drawbacks mentioned with reference to the prior art.
  • connecting fasteners so-called clips, e-clips or fast-clips
  • One particular aim of the invention is to reduce the sound pressure generated by the application machine in the work cycle and also in the intervals of inactivity of the oleo-dynamic actuator during which the combustion engine is in any case on.
  • a further particular aim of the invention is to reduce fuel consumption and pollutant emissions, as well as to increase the stand-alone operation of the application machine for the same weight and volume of the fuel tank.
  • Yet a further aim of the invention is to reduce the risk of overheating the hydraulic oil and, thus, limit the total volume, and to simplify and economise the entire hydraulic circuit, for example by removing the radiator as an additional component and relative hydraulic connections.
  • reference numeral 1 globally denotes an application machine for the application and/or removal of connecting fasteners 2 (so-called e-clips or fast clips or Pandrol clips) for the connection of a rail 3 to a tie 4 of a railway track.
  • the application machine 1 comprises:
  • the control device 19 comprises an adjusting device 20 of an accelerator 21 of the engine 15, which (automatically) adjusts the number of revolutions of the engine 15 depending on the actuation of the oleo-dynamic actuator 10.
  • the adjusting device 20 adjusts the accelerator 21 so as to increase the number of revolutions of the engine 15 during the actuation of the oleo-dynamic actuator 10 with respect to a reduced number of revolutions during non-actuation intervals of the oleo-dynamic actuator 10.
  • the number of revolutions of the internal combustion engine 15 is adjusted in real time to the momentary kinetic energy needs of the pump 16 which requires a lot of energy at the time of driving the oleo-dynamic actuator 10 for inserting and extracting the connecting fasteners 2, little energy at the time of the return of the oleo-dynamic actuator 10 from an advanced working position to a rearward rest position and, theoretically, no energy during the pause or non-operation intervals of the oleo-dynamic actuator 10.
  • the number of revolutions of the engine 15 is adapted in real time to the need to save fuel and reduce noise and pollution, lowering fuel consumption and noise and pollutant emissions to the minimum necessary in the pause or non-actuation intervals of the oleo-dynamic actuator 10, as well as during the return of the oleo-dynamic actuator 10 from the working position to the rest position.
  • the adjusting device 20 of the accelerator 21 may comprise a gear motor with an encoder connected to the accelerator 21 and suitable to adjust the accelerator 21 position (which in turn determines the number of revolutions of the motor) according to an acceleration ramp or curve optimised for operation of the machine 1.
  • the adjusting device 20 of the accelerator 21 may comprise an electromagnetic actuator (solenoid) connected to the accelerator 21 and suitable to switch the accelerator 21 into just two positions corresponding to "a high number of revs" and “low number of revs ".
  • an electromagnetic actuator solenoid
  • the application machine 1 comprises an electric current generator 22, for example an electric alternator connected to the engine 15 and configured to generate, even at the lower number of revs of the engine 15 switched on, an electric current sufficient to power the driving and control device 19 as well as for any lights 23 for lighting an operational area of the machine 1.
  • an electric current generator 22 for example an electric alternator connected to the engine 15 and configured to generate, even at the lower number of revs of the engine 15 switched on, an electric current sufficient to power the driving and control device 19 as well as for any lights 23 for lighting an operational area of the machine 1.
  • the pump 16 is a two stage oleo-dynamic pump which switches by means of a limiting valve, depending on the oil pressure, between:
  • the limiting valve on the pump 16 switches from the two-stage configuration to the single-stage configuration.
  • the pump 16 is a two stage gear pump, per se known (see for example EP0811165B1 , DE3520884 ) and thus not described or illustrated in detail, which allows the aforesaid switching of the pump in synergic combination with the adjustment of the accelerator of the engine and with the work cycles of the thrust assembly 8.
  • the oleo-dynamic circuit 17 comprises a reservoir 28 forming an inlet opening 25, an outlet opening 26, a cooling wall 27 which may have cooling tabs projecting outwardly of the reservoir 24, and an internal oil path 28 extending from the inlet opening 25 to the outlet opening 26 and having a thermal exchange section arranged between the inlet opening and the outlet opening, and extending along the cooling wall 27 (see the schematic illustration in figure 4 ).
  • the thrust assembly 8 comprises two opposite levers 29, rotatably mounted on two sides of the frame 5 about respective axes and only one oleo-dynamic actuator 10 connected with both levers 29 to move them in a counter-direction, wherein one of the thrust members 9 is mounted at each of the two levers 29.
  • each of the thrust bodies 9 forms at a first end an inserting tool 30 (made for example as a thrust block) for inserting the connecting fastener 2 and, and at a second end, an extracting tool 31 (made for example as a hook) for extracting the connecting fastener 2, and each of the thrust bodies 9 can be turned or tipped over and blocked or restrained in:
  • the thrust member 9 is hinged to the lever 29 by a hinge 32 lockable in the extraction and insertion positions and releasable by means of a locking knob 33 ( figures 9, 10 ).
  • the hinge 32 may also comprise a retention spring 34 which facilitates the rotation of the thrust member 9 and keeps it in the chosen position.
  • the thrust assembly 8 comprises a counter frame 35 rigidly connected to the frame 5 and having two counter surfaces 36 opposite and directly facing the rail 3, preferably at the profile of the rail base, or at the joint 13 of the tie 4, on two opposite sides of the rail, so as to form a counter support during an extraction movement of the thrust assembly 8.
  • the counter-frame 35 is in the shape of a horseshoe, suitable to extend astride the rail profile and the thrust members 9 are movable with respect to the counter-frame 35 moving towards each other (insertion) or away from each other (extraction) transversally to the longitudinal direction of the rail 3. This way torques on the machine caused by the extraction thrust are avoided and the risk of tipping over the machine 1 itself is overcome.
  • the frame 5 may form a platform or central portion 37 to which the thrust assembly 8 and the actuation assembly 14 is connected, a front supporting arm 38 extending from the central portion 37 toward a front side of the machine 1 and having one or more rollers 6 for a front support of the frame 5 on the rail 3, and a rear support arm 39 extending from the central portion 37 toward a rear side of the machine 1 and having at least one roller 7 for a rear support of the frame 5 on the rail 3.
  • the rear arm 39 is connected with the central portion 37 by a rotary joint 40 with a spring 41 that is preloaded as to solicit (with the machine 1 resting on the rail) the central portion 37 with the thrust assembly 8 against the force of gravity upwards in a raised waiting position with respect to the front and rear supports (rollers 6, 7) and to allow the operator to push the central portion 37 with the thrust assembly 8 against the spring pre-load 41 downwards in a lowered position where the thrust members 9 can engage the connecting fasteners 2 positioned on the tie 4 (and possibly partially pre-inserted in the mounting attachments 13).
  • the preload of the spring which acts between the central portion 37 and the rear arm 39 of the frame 5 is adjustable to adjust the raised waiting position and be able to adapt the resistance of the frame 5 to lowering, to the individual preferences of the user. This facilitates the use of the application machine 1 and reduces operator fatigue.
  • the spring 41 comprises a gas spring connected to a first point or fulcrum 42 in the rear arm 39 away from the rotary joint 40 and a second point or fulcrum 43 of the central portion 37 away from the rotary joint and from the first fulcrum 42 so that the central portion 37, the rear arm 39 and the air spring 41 form an articulated triangle, and wherein the position or distance of one of the first 42 and second points or fulcrums 43 (preferably of the second point 43) in relation to the rotary joint 40 is adjustable, for example by means of an adjusting screw 44 with a manual knob to adjust the preload torque exerted by the air spring on the axis of the rotary joint 40.
  • the thrust assembly 8 comprises a lifting device 45 to lift the tie against the rail, and the control device 19 drives the lifting device 45 automatically depending on the actuation of the oleo-dynamic actuator 10, so that the lifting of the tie 4 takes place during an initial phase of insertion of the Fastclip fastener in which the Fastclip fastener does not yet engage the profile of the rail base 3 but is already partially fitted into the joint 13 of the tie 4 and the joint 13 of the tie 4 is thus already engaged with the thrust member 9.
  • the lifting device 45 comprises:
  • the lifting piston 47 is moved by an oleo-dynamic piston-cylinder lifting assembly 48 automatically controlled depending on the oleo-dynamic pressure in the oleo-dynamic actuator 10, in particular by means of a group of pressure-controlled passive valves 49.
  • the insertion cycle of the Fastclip springs occurs in the following sequence:
  • the user actuates the control member 51 and the control device 19 drives the control valves 18 of the oleo-dynamic circuit 17 which supplies pressurised oil to the oleo-dynamic actuator 10.
  • the oleo-dynamic actuator 10 moves from the rest position toward the insertion position and the thrust members engage the Fastclip fasteners and insert the palettes 46 under the latter.
  • the thrust members 9 push the Fastclip fasteners into the corresponding joints 13 of the tie 4 and the resistance to the insertion of the connecting fasteners increases the pressure of the oleo-dynamic fluid in the actuator 10.
  • the group of pressure-controlled passive valves 49 switches the oleo-dynamic circuit 17, so as to stop or slow down the further advancement of the oleo-dynamic actuator 10 and (pressurise the oleo-dynamic piston-cylinder lifting assembly 48 so as to) lower the lifting piston 47 against the rail 3 so that the thrust members 9 lift the tie 4 to rest against the rail 3.
  • the support of the tie against the rail entails an increase of the fluid pressure up to a further threshold value, which ensures the lifting of the tie against the rail, upon the achievement of which the group of pressure-controlled passive valves 49 switches the oleo-dynamic circuit 17, so that the oleo-dynamic actuator 10 and the thrust members 9 continue their stroke as far as the insertion position, completing the insertion of the Fastclip fastener above the rail base with the tie 4 moved correctly towards the latter.
  • the control device 19 comprises a cycle selection member 50, for example a lever, knob, or push-button for a manual selection between an application cycle of the connecting fasteners 2 and a removal cycle of the connecting fasteners 2 (differing substantially in the direction of movement of the oleo-dynamic actuator 10), as well as an actuating member 51, for example a push-button, for the manual actuation of the cycle pre-selected by the cycle selection member 50, wherein the same actuating member 51 actuates both the application and the removal cycles of the connection fasteners 2.
  • a cycle selection member 50 for example a lever, knob, or push-button for a manual selection between an application cycle of the connecting fasteners 2 and a removal cycle of the connecting fasteners 2 (differing substantially in the direction of movement of the oleo-dynamic actuator 10)

  • control device 19 comprises a memory and stores in the memory the number of insertion/extraction cycles and/or the total number of hours of operation, and generates an acoustic and/or visual maintenance alert depending on the number of hours of operation and/or of the number of cycles and predetermined maintenance intervals.
  • the actuating assembly 14 forms a module that is free-standing and removably connectable to the frame 5, and comprises two front handles 52 formed on a front side of the actuating assembly 14 and two rear handles 53 formed on a rear side of the actuating assembly 14 which permit the gripping and transport of the actuating assembly 14 by two people (one in front and one behind), as well an operating handle 54 with two handles 55 and at least one actuating member 51, for example a push-button or a lever, wherein the operating handle 54 is movable, for example, can be tipped between an operative position, wherein the operating handle 54 is extended outwardly of the actuating assembly 14 in the direction of the rear side, and a transport position, wherein the operating handle 54 is collapsed inwardly of the actuating assembly 14.
  • the operating handle 54 can be locked in the operative position by a friction or snap locking device 56 configured to:
  • the locking device 56 In case of lifting the actuating assembly 14 with the operating handle 54 extended in the operative position, the locking device 56 would gradually yield, preventing actions that could injure the operator or damage the application machine 1.
  • the locking device 56 comprises one or more pairs of friction surfaces which can be clamped against one another and detached from one another by means of a locking knob 58.
  • the friction surfaces are made, one on the operating handle 54 and the other on a frame of the actuating assembly 14, preferably at a tipping hinge which connects the operating handle 54 to the (frame) of the actuating assembly 14.
  • the operating handle 54 can be completely detached from the actuating assembly 14.
