Definitions

  • This invention concerns improvements to platelayer waggons for rails.
  • the invention concerns improvements to mechanical platelayer waggons for rails, the platelayer waggons being of the type described in the pending application No.83487 A/83 for a patent in Italy in the name of the present applicant.
  • This type of platelayer waggon consists of a self-propelled waggon which is equipped with several stores to distribute clips for fixture of the rails and also to distribute the relative accessory components, namely bolts, washers and nuts.
  • Patent FR-A-2.253.872 discloses a device for the pre-assembly of fixture elements (clips, nuts and washers).
  • Several guides deliver these components to a rotary pre-assembly table.
  • the oomponents are taken by means of an arm and placed in a suitable position for their final installation by suitable means, which are not disclosed, nor is it disclosed how the final installation takes place.
  • Patent FR-A-2.295.170 discloses a self-propelled machine particularly intended for the removal of components that anchor the rails. This machine comprises various work units or tools (9-10-11-12) suspended below the machine and able t.o move synchronously with the forward movement of the machine.
  • Patent FR-A-2.021.555 is directed in particular to the alignment of the tools in relation to the working station; this is obtained by having the tools themselves fitted resiliently in relation to their support trolley.
  • the machine shown as an example is intended only to screw and unscrew the nuts and forms a part of a wider system to renew the rails which comprises other machines that are neither described nor shown.
  • a purpose of this invention is to improve the placement of such components.
  • the invention can also be adapted for the placement of components either for so-called "K” type attachments or for "Nabla" attachments or for other types of indirect attachments.
  • the number of the guides which deposit the components will be adapted to the number of components to be assembled at each fixture point.
  • Another purpose of this invention is to provide a pre-assembly of components before they are deposited.
  • the invention envisages that the outlets of the guides which deliver the clip, the washer and the nut to be screwed onto the bolt respectively are positioned next to each other at a point lying downstream from the position of placement of the bolts.
  • a bolt is deposited first by means of an appropriate guide.
  • the clip the washer and clamp nut, already pre-arranged in an assembled position, are deposited then on this bolt by positioner means envisaged in the invention.
  • the invention enables positioning mistakes, such as an oblique positioning of the bolt in relation to the vertical, to be corrected.
  • the invention provides also pre-positioner means which can perform assembly of the clip, washer and nut leaving their respective guides. In this way any possibility of mistakes in the depositing of the individual components is obviated.
  • the invention visualises also a .pre-engagement of the nut with the end of the relative bolt.
  • the pre-positioner means include a positioner pin means, which is movable suitably and can lodge momentarily the above components in the order in which they are to be fitted.
  • This positioner pin is mounted on trolley means, so that the pre-positioned components remain unmoved in relation to the position at which they are to be tightened by being screwed onto their respective bolt, which has already been positioned in relation to the rail, when the waggon moves forward.
  • engagement means are provided which cooperate momentarily with the foregoing components (clip, washer and nut) pre-assembled on the positioner pin means.
  • the engagement means take such components from the positioner pin means.
  • the engagement means and the pre-assembly means are visualised as being able to move reciprocally in a transverse direction. The purpose of this is to enable the pre-assembled components to be engaged and to be released from the pre-assembly means and to be positioned on the bolt which has already been deposited.
  • engagement means may be immovable in a transverse direction while the pre-assembly means can move transversely, or vice versa.
  • Such pre-assembly means and engagement means can also be envisaged as being movable, both of them, in a coordinated manner crosswise to the rail.
  • the engagement means of the invention are equipped with means able to apply a pre-screwing action of some turns to the nut against the bolt.
  • This clamping device too can be moved in relation to the waggon in such a way as to remain momentarily unmoved in relation to the position where the nut is screwed down.
  • the pre-assembly means have a return path displaced sideways in relation to their forward movement so as not to come into contact with the components deposited just beforehand in correspondence with the rail.
  • the present invention is therefore embodied with improvements to platelayer waggons for rails, the platelayer waggons being of a self-propelled type equipped with positioner trolley means and guide means to deposit components for fixture of the rails, the improvements being characterised by comprising positioner unit means together with means to pre-assemble at least a part of such components before the latter are fitted.
  • a platelayer waggon for rails bears the reference 10.
  • a part of the platelayer waggon 10 is shown which comprises a portion of a frame 11 on which a cab 12 lodging an operator 13 is supported in a known manner.
  • the operator 13 has the task of introducing into appropriate guides the components withdrawn from suitable stores, which are not shown here but are arranged in a suitable position in the platelayer waggon 10.
  • the figure shows a guide 17 for bolts, a guide 18 for clips, a guide 19 for washers and a guide 20 for nuts.
  • This device 14 is located substantially centrally to and below the frame 11 of the waggon 10, as is already known from the cited pending application No.83487 A l '83 for a patent in Italy in the name of the present applicant.
  • Such trolley 14 has wheels 15 able to cooperate with a rail 16, these wheels 15 having a conformation suitable for obtaining automatic alignment of the positioner device 14 in relation to the rail 16 according to methods described in the patent application cited above.
  • the outlets of the clip guide 18, washer guide 19 and nut guide 20 are located in the order indicated and close to each other in correspondence with a positioner unit 29 supported by the above positioner device 14.
  • the whole positioner unit 29 can move; according to the invention the unit 29 can move lengthwise to the rail 16 but can also be envisaged as being able to move also crosswise to the rail for any requirements of crosswise positioning or alignment of the components.
  • Fig.2 shows in particular the positioner unit 29 with the outlets of the various guides.
  • a clip 22, washer 23 and nut 24 can be seen in their release positions at the outlets of the respective guides 18, 19 and 20.
  • the above components 22-23-24 are those which are deposited in the event of "K” type attachment of the rails to the sleepers, but it is possible to employ the invention with other types of indirect attachment, such as "Nabla” type attachments where a vibration-damper support seating and relative washer and nut are deposited.
  • a pre-assembly means 25 cooperates momentarily with the outlets of the guides 18-19-20 and comprises a movable support 26, which is shaped like a bracket and bears a pre-assembly pin 27 at its end.
  • This pin 27 collects in succession, while moving towards the rear of the platelayer waggon 10, the components 22, 23 and 24, which are pre-assembled thus on the pin 27 before being deposited on the rail 16.
  • Figs.3 and 4 show engagement,or withdrawal, means 30, which transfer the nut 24, washer 23 and clip 22, already assembled on each other, from the positioner pin 27 to a bolt 21 already placed in its position by the positioner unit 28.
  • the engagement means 30 include two jaws 31, which are clamped against the clip 22 by the action of two stationary cams 35 that cooperate with rollers of the jaws, as is shown in the figure.
  • actuator means 34 which in this case consists of a jack.
  • a screw-tightener headstock 32 is located in the centre of the jaws 31 and has a shape able to cooperate with the nut 24 for pre-application of the nut 24 by being screwed onto the bolt 21.
  • the headstock 32 is always kept in rotation and is displaced vertically together with the jaws 31 by the action of the actuator 34.
  • the pre-screwing of the nut 24 has to be performed only so as to lay the nut 24 on the end of the bolt 21; the headstock 32 can therefore have a form such as not to be able to tighten the nut 24 fully, that is to say, a form able to produce only a slight screwing and then to release the nut 24 at once, or else the headstock 32 can be provided with a clutch or other means to limit the torque exerted on the nut 24.
  • the headstock 32 is powered by a motor unit 37 of a known type located in the upper part of the positioner device 14.
  • a guide column 33 can be seen in Figs.3 and 4 and can slide within a side frame 38 of the device 14.
  • the support 26 with the pin 27 bearing the pre-assembled components 22-23-24 now moves towards the inside of the waggon 10 and closer to the rail 16 in correspondence with position A4.
  • the components 22-23-24 are brought into the zone of the engagement means 30, which are located in the position shown with B4 and lines of dashes in Fig.7 (see also Fig.5).
  • the engagement means 30 are lowered by the action of the actuator means 34 onto the pre-assembled components 22-23-24 and are then raised (position B5) while the whole assemblage is displaced towards the front of the waggon 10 (see also Fig.7).
  • the positioner unit 29 is displaced further towards the front of the waggon 10 and the engagement means 30 are lowered (position B6).
  • the pre-screwing operation now begins (position Bl coinciding with B6).
  • the whole positioner unit 29 is displaced in relation to the waggon 10 with a speed equal and contrary to the speed of the waggon 10 in relation to the rail 16 and remains clamped to the rail 16 by a gripper which is not shown here. In this way the positioner unit 29 is not moved in relation to the position of the bolt 21.
  • the engagement means 30 are lowered progressively (from Bl to B2), so that they bring the clip 22,and washer 23 so as to be threaded onto the bolt 21, and thereafter the rotation of the headstock 32 (from B2 to B3) brings the nut 24 onto the end of the bolt 21 and screws the nut 24 onto the bolt 21 by a few turns.
  • the engagement means 30 are then released (position B3) by the opening of the jaws 31 and the raising of the headstock 32, which disengages the nut 24.
  • Fig.4 shows an orientation means or feeler 36, which has the function of orienting the bolt 21 properly if the latter 21 is positioned wrongly.
  • the feeler 36 may consist, for instance, of a fork which is positioned against the bolt 21 and keeps it 21 in a vertical position for the correct lowering of the engagement means 30 and the corresponding positioning of the pre-assembled components 22-23-24 on the bolt 21.
  • clamping means 43 which may comprise, as in the figure, a clamping headstock 45 fitted to a trolley 44 and powered by suitable motor means 46 takes action.
  • the trolley 44 can be moved suitably in the direction of forward movement of the waggon 10 so as to remain unmoved in relation to the rail and therefore to the components 21-22-23-24 to be tightened.
  • horizontal actuator means 47 consisting of a jack means or screw-threaded means, for instance.
  • Vertical actuator means 48 enable the clamping headstock 45 to be lowered until it 45 engages the nut 24.
  • lightening is carried out by actuation of the headstock 45 by the motor means 46.
  • Means to regulate torque such as a clutch or like means may be included.
