Definitions

  • the present invention relates to the field of railroad equipment and more precisely to an improved device for locking the wheels of vehicles on a railroad car used for their transport.
  • a first embodiment of said prior device comprises a rod which can be fixed in one of said grooves and a substantially tubular sliding guide on said rod, on which a support plate for the stopping means of the wheel of the vehicle to be locked is provided.
  • Said stopping means is inclined with respect to the track of the wheel, so that, to lock the latter on the platform of the railroad car, it is sufficient to introduce the rod into the groove closest to the track of the wheel and move the plate along the rod by means of the guide which slides in the groove until the stopping means meets the wheel. At this point, to fix the position of the stopping means with respect to the wheel it is sufficient to introduce a protruding pin of the guide into one of the several longitudinal holes formed in the rod.
  • the device according to this first embodiment is very simple to construct and to utilize, in that it requires only one adjustment in a direction transversal to the wheel.
  • the device is suitable only for light vehicles, such as automobiles, and it is not proper for heavier vehicles, such as trucks, for which the forces derived from braking or curving of the train are significantly greater.
  • the device has two adjustments, one in a transversal direction similar to the previous one, and one in a longitudinal direction obtained by means of a mobile plate carrying the stopping means and a fixed plate integral with a tubular guide and in which the mobile plate slides.
  • the position of the fixed plate with respect to the mobile one is adjustable by means of a pair of hooks which are introduced into a pair of holes created in the fixed plate and in holes placed along two rows formed in the mobile plate.
  • the device is then fixed in the groove closest to the track of the wheel, then its position is adjusted first in a transversal direction as previously described, and then in a longitudinal direction, until the stopping means meets the wheel.
  • the two adjustments are independent and must be carried out separately, requiring increased positioning time of the device for each wheel and a greater difficulty in manoeuvrability.
  • the stopping means of the device according to the above cited prior patent application has been proven inadequate, in that the mobile plate, pressed by loads which burden the stopping means itself, sometimes becomes deformed permanently and the device is damaged.
  • the object of the present invention is to provide an improved device for locking the wheels of vehicles on a railroad car used for their transport which is easy to construct, of simple, easy and safe manoeuvrability from the stand point of the workmen, and which is sturdy and load resistant without deformations in its structure.
  • the locking device is suited for locking the wheels of vehicles on a railroad car used for their transport and having a platform with parallel transversal grooves, and comprises, in common with the locking device according to prior filed EP-A-0 442 245, stopping means for one of the wheels of the vehicles, a rod, with a plurality of longitudinally spaced holes, which can be fitted in one of the grooves and a guide which slides on said rod and is integral with a base with which a support element for the stopping means of the wheel engages slidingly.
  • the support element for the stopping means comprises an elongate structure with box-type ends to one of which the stopping means is fixed and a plate, which guides the sliding of the base, said plate extending in fixed relation between said ends and provided, in the middle part comprised between said ends, with a plurality of holes.
  • Retractable locking means engageable contemporaneously with the plate of the support element, the base and the rod are provided for in order to lock with a single manoeuvre the relative movements.
  • a stopping equipment for said mobile locking means is provided for.
  • the device according to the invention has the advantage of easy adjustment of the position with respect to the wheel and of increased sturdiness under heavy loads.
  • the advantage of easy manoeuvrability is very important, mainly taking into account the number of operations of this type which the railroad workmen assigned to the locking and releasing of wheels of vehicles on railroad car platforms carry out for a train load.
  • 1 generally indicates a transversal portion of a lane of a platform of a railroad car of a known type, for the transport of various types of vehicles.
  • the lane has longitudinal external 2 and internal 3 edges and is made in fretted sheet, comprising a plurality of transversal grooves 4 delimitated by corresponding projections 5 on each of which there is formed a row of holes 6 drawn towards outerside with a sharp edge in order to increase the adherence of the tires to the platform itself.
  • the above mentioned figures also illustrate the improved device for the locking of the wheel R of a vehicle, indicated generically by 7, comprising stopping means 8 and 9 for said wheel fixed to an elongate support element 10 with box-type ends 10a and 10b to which there are fixed the ends 11a and 11b of a substantially rectangular plate 11 with a central part raised in a longitudinal direction and provided with holes 12, in the central middle portion, which are positioned in two rows illustrated with dashed lines in figure 4.
  • the lower central portion of the element 10 has a wide opening 13 in which an internally hollow base 14 is slidingly engaged with the middle portion of the plate 11 which is suspended between its two ends 11a and 11b.
  • Mobile locking means with the element 10 and the platform 1 as well as a stopping equipment of the mobile locking means are fixed to the base 14.
  • two flat supports 15, having an elongated circular hole 15a in which a tubular sleeve 16 is slidingly and rotationally engaged are fastened in a protruding way to the base 14 on the side facing the end 11b of the plate 11.
  • a flat arm 17 is fastened with one end to the tubular sleeve 16 and has at the other end a forked pin 18.
  • a laterally bent projection 17a extending orthogonally to the latter is provided for.
  • To the lower face of the base 14 a tubular guide 19 in which a channel section rod 20 is slidingly engaged is fastened.
  • the channel section rod 20 has a plurality of equally spaced holes 21 made in its horizontal wall and is provided with a projecting plate 22 positioned orthogonally to the rod 20 itself and comprising a pin 23 engageable with one of the holes 6 of the platform 1.
  • the forked pin 18 in figure 1 is shown with its ends introduced in two holes 24 formed on the upper face and, correspondingly, on the lower face of the base 14, as well as in a pair of holes 12 formed on the plate 11 and in a pair of holes 21 of the rod 20.
  • a tubular manoeuvring handle is also illustrated which is bent substantially in a L-shape, one end 25a of which is suited to be grasped by a user, while the other end 25b is slidingly engaged in the tubular sleeve 16 and has at its end a shoulder 27 against which one end of a spring 28 operates while the other end of the spring urges against the sleeve 17.
  • the handle 25 also has a pivot 29, bent at right angle which can engage with an open seat 30 formed in one of the flat supports 15 and with a saddle seat 26 formed in the projection 17a which extends from the arm 17.
  • an auxiliary gripping handle 31 fastened on a side face of the support element 10 is provided for.
  • the locking device 7 is prevented from being separated from the rod 20 by means of a hook 20a, fixed to one end of the rod, and the projecting plate 22, fixed to its other end, preventing complete extraction of the rod from the guide 19 which is integral with the device 7 and in which the rod 20 itself slides.
  • the pin 23 is introduced into one of the holes 6 of the platform 1 and contemporaneously the rod 20 and the tubular guide 19, in which the rod 20 slides, are placed in the groove 4 of the platform itself.
  • the chosen groove 4, and therefore the row of holes 6, is that which is closest to the track of the wheel R which must be locked.
  • the positioning of the stopping means 8 and 9 against the track and a side face of the wheel R is carried out by pulling the spring loaded handle 25 until the shoulder 27 compresses the spring 28 against one of the enlarged edges of the sleeve 16 and, therefore, until the right-angled pivot 29 disengages the seat 30 and allows for the rotation of the handle 25.
  • the next step is to release the handle 25 itself which, under the force of the spring 28, returns to a resting position pulling the right-angled pivot 29 back to the seat 30 of the supports 15 and thus preventing accidental rotation of the handle 25.
  • the hole 15a of the flat supports 15 is elongated in order to allow the pin 18 to be entered or extracted from the holes 12, 24 and 21 because the axes of these holes do not lie on the circular trajectory that the pin 18 should follow.
  • the locking device 7 therefore requires, as described above, a single manoeuvre to carry out the operations of positioning the stopping means 8 and 9 against the wheel resting on the platform. Furthermore the box-type form of the support element 10 and the presence of the plate 11 allow for a better and more strong distribution of the load which is derived from the sharp movements of the railroad car on which the platform 1 is mounted. Infact, the load burdening the stopping means 8 and 9 is distributed on the lower faces of the ends 10a and 10b of the support element 10, which rests on the numerous drawn holes 6 of the projections 5 of the platform 1.
  • the device described above has been proven efficient also in the case of ice formation and dirt deposits and incrustations, in particular in correspondence with the pin 18. This is due to the length of the arm 25a which allows, with a not very strong force, the extraction of the fork 18 from the holes with which it is engaged even in these cases of greater resistance.
