Definitions

  • the present invention relates to an arrangement and devices for loading and positioning a semi-trailer in another trans­port vehicle, precisely on its center line so that the permis­sible projection of the load is not exceeded on either side of the transport vehicle when a load of maximum width is being transported.
  • the invention relates in particular to a posi­tioning arrangement for use in loading a trailer or the like into another transport vehicle, the freight space of which is movable at least in part to the side from the transport vehicle itself and the trailer or the like on its wheels is pushed into the freight space moved to the side and is sup­ported in it, and when the freight space has been returned into connection with the frame of the transport vehicle the front part of the trailer or the like is locked by means of a support table or the like so as to be immobile in the lateral direction on the center line of the transport vehicle.
  • Application FI-882564 describes one way of centering a semi­trailer when loading it onto a freight wagon opening from the side.
  • the front part of the semi-trailer is centered by means of a specially structured support table on the center line of the freight wagon and its rear part remains in the position in which it was parked.
  • the sup­port table according to application FI-882564 is heavy to use and requires great manual strength from the loading personnel.
  • the object of the invention is to provide a positioning ar­rangement by means of which the front part of the trailer can be centered precisely and easily so that fastening by the tow­bar precisely on the center line of the transport vehicle is possible.
  • Another object of the invention is a positioning arrangement by means of which the rear part of the trailer can simultaneously be centered with sufficient precision on the center line of the transport vehicle. It is a further object of the invention to provide a positioning arrangement which is simple in structure and reliable in operation.
  • both ends of a trailer or the like can be centered rapidly and reliably.
  • the loading time becomes short, which is economically advantageous, and the trailer or the like can be guided and secured to the transport vehicle so that no part is damaged during loading and transportation.
  • the loading does not require any steps physically dangerous for the personnel.
  • Figure 1 depicts a side elevation of a freight wagon 1 for the transport of a semi-trailer 2.
  • Figure 2 depicts the same freight wagon, in which the dot-dashed lines depict the box 3 of the wagon, with its side wall 4, pivoted out from the freight wagon 1, in which case the semi-trailer or the like can be driven along a ramp or a separate driving bridge 35 onto and off the box 3 of the wagon.
  • the frame of the freight wagon is indicated in general by numeral 5, and at one end of the frame there is secured a support table 6 according to the invention.
  • a lifting table 7 according to the invention and wheel guides 8 according to the invention are secured to the box 3.
  • Figure 3 depicts a support table 6, which can move on slide bars 9 in the longitudinal direction of the wagon.
  • the support table 6 is depicted as seen from the side, sec­tioned through the center line A-A.
  • the support table 6 can be moved on slide bars 9 by a hand crank 13 with the help of a gear 15 driven by chain transmission 14 and of a gear rack 16 in the support table 6.
  • the support table 6 has a conventional system for locking the tow-bar of the of the trailer into an aperture 17 by means of a fork 19 operated by a hand lever 18.
  • FIGS 5 and 6 depict side elevations of the lifting table 7 in the box 3 pivotable to the side, in its extreme vertical positions
  • Figures 7, 7a, 7b depict plan views of the same in the center and in both lateral-transfer positions of the centering devices 23.
  • the lifting table comprises a bridge 21, parallel to the longitudinal direction of the box and secured by an articulation 20 to the box 3; the other end of the bridge can be raised by hydraulic cylinders 22.
  • the bridge 21 has trailer-centering devices, indicated in gen­eral by reference numeral 23, at that bridge end which is raisable by the hydraulic cylinders 22.
  • Figures 7a and 7b depict the structure and operation of the centering devices 23.
  • two single-acting hydraulic cylinders 24a and 24b acting in opposite directions are coupled by their frames to the bridge 21, and the piston arms 32a, b of the cylinders are interconnected by a spring-loaded equalizing bracket 25 so that mutually similar springs 26a and 26b will induce the return movement of the cylinders 24a, 24b when the hydraulic pressure in the cylinder decreases.
  • a flange 31 located between the springs 26a and 26b and movable in relation to the bracket 25 is secured on the center line of the bridge 21, in which case, when pressure is removed from the cylinders, it will pull in under the effect of the springs and center, in relation to the bridge, both pistons and the rams 27a and 27b in their arms 32a, 32b.
  • the piston arms 32a, 32b, and the rams 27a, 27b are fixedly secured to each other, and the bracket 25 by way of the flange 31 to the bridge 21.
  • FIGS 8 and 9 show perspective representations of the lift­ing table 7 with its parts and support legs 28 which are in the trailer and can be partly turned up.
  • the frame of the trailer has a lifting boom 29, which is made up of vertical bars 33 and a transverse pipe 34. Close to the ends of the transverse pipe 34 of the lifting boom there are stops 30a, b, the distance S between them being greater than the bridge width D, but smaller than the sum (D+L) of the bridge width and the travel distance L of the rams 27a, b.
  • Figures 10, 11 and 12 depict the lateral guides 8 for the trailer wheels, located in the box 3, which guides are conical rollers 37 mounted on the sides of the wheel tracks 36a, 36b and at distance H from the bottoms 41 of the wheel tracks, in parallel to the center line B-B of the track, i.e. the box.
  • the conical rollers 37 are typically located on either the inner sides and/or the outer sides of the wheel tracks, always symmetrically in pairs.
  • the rotation axes of the rollers are thus parallel to the longitudinal center line B-B of the track, i.e. the box.
  • the axes of successive rollers may be congruent or at different widths in the transverse direction.
  • the distance P between the outer surfaces of the rollers, if they are on the inner sides of the tracks as in the figures, is approximately equal to, or only slightly smaller than, the inner distance R between the vehicle wheels 39, in which case the rollers will force the trailer to the center of the box reliably, with small force, and without damaging the wheels or axle structures of the vehicle.
  • This is due precisely to the shape and rotation of the rollers 37, the wheels 39 being transferred, by the transfer indicated by arrow 40, from a point on the side to the correct point when the rollers 37 ro­tate under the edge of the wheel 39.
  • rollers 37 are made as double-­cone rollers, in which case the cone portion 38a in the driving-out direction U may be shorter than the cone portion 38b working in the loading-drive direction K.
  • the bases of the cones are against each other and their apices, or apparent apices, are away from each other, i.e. the rollers are thicker in the middle than at the ends.
  • the positioning of the trailer 2 takes place as follows:
  • the box 3 of the freight wagon is in the opened position, indicated by dotted lines in Figure 2.
  • the trailer 2 is driven or pushed along the driving bridge 35 onto wheel tracks 36 on the box 3.
  • the lateral guides 8 force the rubber wheels 39, even when driven somewhat aside, with sufficient precision onto the wheel tracks 36 and the trailer to the center of the box 3.
  • the tow-bar of the trailer is released from the locking in the traction table of the tractor unit, the lifting table 7 is raised to its upper position by means of the hydraulic cylinder 22 and the tractor unit is driven off.
  • the stops 30a, b of the lifting boom 29 of the trailer are pushed, when necessary, alternately from each side by means of the rams 27a, b of the centering device 23, until the front part of the trailer is centered so that the tow-bar will be in alignment with the aperture 17 in the support table 6, also in the lateral direction of the freight wagon.
  • the lifting table 7 is lowered by its hydraulic cylinders, where­upon the tow-bar of the trailer passes into the aperture 17 in the support table and is locked into it by the fork 19.
  • the centering device 23 has become centered as the pressure has been removed, and so it is not in the way.
  • the rubber wheels of the trailer are supported so as to be im­mobile by means of wheel stops, and the freight wagon is ready for transport. When the load is being unloaded, the procedure is similar, but in the reverse order.
  • the invention is not limited to the embodiment disclosed above; the structural details may deviate considerably from that described above. What is essential is that the arrange­ment includes means for centering both ends of the trailer or the like and for locking one end so as to be immobile in the lateral direction.
  • the hydraulic and spring-actuated mechanisms can be implemented also by using other structural parts.
