Definitions

  • the present invention concerns a king pin coupling and a king pin locking device.
  • the king pin coupling is used for locking a king pin of a semitrailer in position on a railway wagon.
  • the semitrailer In such railway wagons configured to receive and carry semitrailers, it is important to keep the semitrailer safely on the railway wagon by securing the semitrailer in relation to the railway wagon.
  • the semitrailer At its front end, the semitrailer has a downwardly projecting king pin which is received and locked in a locking device mounted to the railway wagon.
  • Examples of devices for locking a semi-trailer to a railway wagon are disclosed for instance in DE102009015775A1 .
  • these known king pin locking devices suffer from certain disadvantages.
  • the known king pin coupling is limited in use since the king pin of the semitrailer has to be quite precisely positioned longitudinally in relation to the railway wagon. This is a drawback in particular since semitrailers oftentimes are loaded on the railway wagon in a quite rough manner by the towing truck.
  • Another drawback is that the known king ping coupling is of complicated structure involving a plurality of components, which adds on costs.
  • An object of the present invention is to provide a novel king pin coupling and a novel king pin locking device which is improved over prior art.
  • a king pin coupling for locking a king pin of a semitrailer to a railway wagon.
  • the king pin coupling is mounted to the railway wagon and it comprises a slide having an aperture configured to receive the king pin.
  • the slide is movable - preferably in a continuously movement - back and forth.
  • the king pin coupling further comprises a locking assembly arranged on the slide.
  • the locking assembly defines an open state and a closed state, wherein pivotable locking jaws of the locking assembly in the closed state are configured to grip and lock the king pin in the aperture of the slide.
  • a king pin locking device for locking a semitrailer to a railway wagon.
  • the king pin locking device comprises a base portion and a top portion connected to the base portion.
  • the top portion is vertically movable relative the base portion.
  • the top portion comprises an open space in which a king pin of a semitrailer can be received.
  • the king pin locking device further comprises a king pin coupling having a slide arranged in the open space of the top portion.
  • the slide has an aperture configured to receive the king pin, and it is movable in a longitudinal direction of the open space - preferably in a continuous movement - back and forth.
  • a locking assembly is arranged on the slide, and it defines an open state and a closed state, wherein locking jaws of the locking assembly in the closed state are configured to grip and lock the king pin in the aperture of the slide.

  • the curved parts 27a, 27b are moved into the respective recess 14'a and 14'b for engagement therein.
  • the leg portions 23a, 23b of the jaw locking clamp 18 are abutting front sides of the curved parts 27a, 27b of the locking jaws 17a, 17b, preventing relative movement between the locking jaws 17a, 17b and the jaw locking clamp 18.
  • the sizes of the curved parts 27a, 27b of the locking jaws 17a, 17b are such that when the locking jaws 17a, 17b are in the closed position the leg portions 23a, 23b of the jaw locking clamp 18 are free to pass the locking jaws 17a, 17b.
  • the king pin coupling further has an indicator or inductive sensor 18' to sense when the jaw locking clamp 18 is in the position locking the locking jaws 17a, 17b in their closed state.
  • the indicator 18' then sends a stop signal to the longitudinal drive assembly 9, 30, whereby the movement of the slide 8 is stopped.
  • a locking boss 28 is arranged on the slide 8 and projects into the opening 24 formed when the locking jaws 17a, 17b are in the closed state.
  • the locking boss 28 is arranged to extend through the housing 34 of the slide 8, and it will project into a groove of the king pin 3 of the semitrailer 2 when the king pin 3 is received inside the opening 24, whereby vertical movement of the king pin is hindered.
  • the locking boss 28 may be retracted against the action of a spring to release the king pin 3, if vertical movement upwards of the king pin 3 is desired when the locking jaws 17a, 17b are in the closed state.
  • An indicating device 29 is placed partly projecting above one of the side pieces 11a, 11b of the top portion 6 of the king pin locking device 4.
  • the indicating device 29 is received at a pivot at one end, and a part of the indicating device 29 opposite the end received at the pivot extends up through a slot in the side piece 11a of the top portion 6.
  • the part of the indicating device 29 received in the slot of the side piece 11a is urged upwards by means of a spring.
  • each scissor lift 7 is controlled by a bar 31, the end of which is moved inwards or outwards by rotation in a nut 32 at one end of the scissor lift 7.
  • the bars 31 of the scissor lifts are interconnected to give the same rotation and so that the scissor lifts 7 are moved in unison.
  • the design of the scissor lifts 7 may vary, and the embodiment shown herein is just an example.
  • An open space 37 is formed in the top portion 6 between the parallel side pieces 11a, 11b, the second piece 13 and the slide 8.
  • the king pin 3 of the semitrailer 2 is to be received.
  • the slide 8 is placed in its foremost position adjacent the first piece 12 of the top portion 6, giving the maximal size of the open space 37.
  • the open space 37 with the slide 8 placed adjacent the first piece 12 of the top portion 6 has a length of about 300 mm and a width of about 100 mm.
  • Plastic sleeves or blocks 33a, 33b and 33a', 33b' are placed at each end of the threaded bars 9a, 9b used to move the slide 8 back and forth.
  • the purpose of these blocks 33 is to take up jerks. In case of big jerks, such as at heavy breaking or collision, the plastic blocks 33 will be deformed protecting the king pin coupling. Hence, these plastic blocks 33 serve as shock absorbing crush elements.
  • a rocker is placed at one of the plastic blocks 33, which rocker (not shown) reacts on longitudinal movement. If the rocker sense a sudden change of speed it will activate a valve, which valve in turn activates the brakes of the railway wagon 1.
  • the operation of the king ping coupling in accordance with the example given is described in the following.
  • the semitrailer 2 is placed on the railway wagon 1 with the king pin 3 of the semitrailer 2 placed above the open space 37 of the top portion 6 of the king pin locking device 4.
  • the slide 8 is placed adjacent the first piece 12 of the top portion 6, giving the maximal open space 37 for receiving the king pin 3.
  • the scissor lifts 7 are activated, whereby the top portion 6 will be lifted, until the indicating device 29 is activated when the top portion 6 hits the bottom of the semitrailer 2.
  • the semitrailer 2 rests on its wheels and on the top portion 6 of the king pin locking device 4.
  • the slide 8 is moved backwards, whereby the inclined second plates 16a, 16b will assist in guiding the king pin 3 into the triangular aperture 36, defined by the inclined second plates 16a, 16b and the locking jaws 17a, 17b.
  • the locking jaws 17a, 17b are held in their open state by means of the jaw locking clamp 18, as shown in Fig. 8 .
  • the locking jaws 17a, 17b hit the king pin 3, the locking jaws 17a, 17b will be turned inwards around the pivots 25a, 25b by the continued movement of the slide 8 backwards, as indicated in Fig. 9 .
  • the jaw locking clamp 18 is pushed backwards by means of the springs 19a, 19b, locking the locking jaws 17a, 17b in their closed state and with the king pin 3 inside the opening 24 formed by the locking jaws 17a, 17b, as indicated in Fig. 10 .
  • the inductive sensor 18' registers that the jaw locking clamp 18 is in the position locking the locking jaws 17a, 17b, the hydraulic motor 30 is stopped, stopping the movement of the slide 8.
  • the slide 8 When the semitrailer 2 is to be unloaded from the railway wagon 1, the slide 8 is moved forward, bringing the semitrailer 2 with it in this movement forward. As the slide 8 approaches the first piece 12 of the top portion 6, the push button 20 will move the jaw locking clamp 18 forward in relation to the locking jaws 17a, 17b by means of the lever 21 connected at one end to the push button 20. As the jaw locking clamp 18 is moved forward, the locking jaws 17a, 17b will no longer be locked and when the inwards projecting parts 22a, 22b of the jaw locking clamp 18 hits the outward projecting parts 26a, 26b of the locking jaws 17a, 17b, the locking jaws will be turned around the pivots 25a, 25b into the open state. The scissor lifts 7 are then activated to lower the top portion 6 out of contact with the semitrailer 2, whereby the semitrailer 2 can be unloaded from the railway wagon 1.
