Definitions

  • the present invention relates to an arrangement and device in transport carriers for locking to each other for the duration of transport a fixed loadbearing structural ele­ment and a structural element, also loadbearing, which can be moved to the side for the duration of loading and un­loading, in such a manner that a rigid joint without a clearance is created between these elements.
  • a special problem area is the attachment of the ends of those loadbearing side walls which are to be turned to the side for the duration of loading and unloading to the rest of the frame structure of the freight wagon, in such a manner that a clearance-­free and rigid joint is obtained which is capable of trans­mitting all tensile and compressive forces, as well as bending forces in the direction of all axles and also tor­sional forces.
  • a clearance-­free and rigid joint which is capable of trans­mitting all tensile and compressive forces, as well as bending forces in the direction of all axles and also tor­sional forces.
  • there is the problem of obtain­ing a joint which is rapid and problem-free to connect and to disconnect.
  • a joint in a transport carrier for example in a freight wagon, a rigid and clearance-free joint between its fixed structure and its movable structure, such as a side wall, which car­ries all tensile and compressive forces, bending forces and torques in different directions.
  • the object is a joint which, when closed, functions quite as if the connected structural elements were of one piece.
  • An addi­tional object is to provide a joint which retains the char­acteristics described above also when subject to pulsating or fluctuating loads. This means that, during use, a clear­ance must not form in the joint under the effect of vibra­tion, and of course the joint must not open.
  • An additional object is to provide a joint which can be locked and un­locked rapidly and simply, as well as reliably, and fits in the available space, which is small. It is a further object to provide a locking which can be accomplished without auxiliary tools.
  • Figure 1 depicts generally a railway freight wagon 1, onto which a semi-trailer 2 has been loaded.
  • Figure 2 depicts the same structure, in which the box 3 and the loadbearing side wall 4 fixedly attached to it are indicated with dot-­and-dash lines in their aside position, at which time the trailer can be driven onto the box 3 along a driving bridge 35.
  • the box 3 and the side wall 4 have been drawn with solid lines in their closed position, which thus corresponds to Figure 1.
  • the rest of the freight wagon frame, to which both the wheel and axle sets of the wagon and the box with its side wall are fastened, is indicated generally by numeral 5.
  • the joint according to the present invention is indicated generally by reference numeral 6; in this embodiment there is a joint such as this only at one end of the box and of the side wall, the other end being hinged to the frame 5 by using hinge means 7. It is also possible to form an embodiment in which both ends of the side wall 4 of the box 3 are secured to the frame 5 by using a joint 6 according to the inven­tion.
  • Figure 3 depicts the railway wagon frame 5 alone, on the basis of which it is evident that the frame 5 alone is not capable of bearing the load, unless it is made very mas­sive; high strength and rigidity also require the securing of the wall, i.e. wall 4, opposite to the side wall 8, tightly at its ends at points 9 and 10 of the frame 5.
  • the locking mechanism 6 is seen from the same direction as in Figure 1.
  • Figure 8 shows, in accordance with this embodiment, a wedge-like protrusion 11 in the frame 5 and a wedge-like groove 12, into which the protrusion 11 is slotted tightly, in the side wall 4.
  • a hydraulic cylinder 13 shown in Figure 2 which pulls the box and the side wall inside the frame 5 of the freight wagon.
  • the side wall 4 moves in the direction of the arrow A, whereupon the wedge-­like protrusion 11 pushes into the wedge-like groove 12 and slots in tightly.
  • the other side surface 14 of the wedge-­like protrusion is straight and approximately parallel to the closing movement A of the side wall 4 at this point of the closing movement.
  • the corresponding side surface 15 of the side wall groove 12, coming against this surface 14, is parallel to the plane 14, and so the surfaces 14 and 15 slide along each other during closing.
  • the side surface 16, opposite to the surface 14 of the protrusion 11, consti­tutes a wedge surface, as does the surface 17 opposite to the side 15 of the groove 12, coming against this surface 16.
  • the protrusion 11 thus forms a truncated wedge, the extrapolated wedge apex of which points from the side of the railway wagon outwards, the straight surface 14 being approximately perpendicular to rhe longitudinal axis of the wagon.
  • the groove 12 is also a groove having the shape of a truncated wedge in the same position, the extrapolated apex of which also points to outside the wagon, in the same direction as the extrapolated apex of the protrusion 11.
  • the length of the wedge-like protrusion 11 and groove 12 is preferably vertical, and in this case parallel to the pivot axis of the hinge 7.
  • the wedge surface 16 of the wedge-like protrusion and the wedge surface 17 of the groove constitute, in the direction of the closing movement A, inclined planes approximately parallel to each other, whereas the straight surfaces 14 and 15 are parallel to each other and to the closing movement A.
  • the end surfaces 33a and b, 34a and b of the said wedge-like protrusions and grooves are also wedge-like and form inclined planes in relation to each other; in each case the apexes, or extra-­polated apexes, of the wedges are perpendicular to the di­rection A of the closing movement.
  • wedge surfaces 16 and 17 form a relatively small wedge angle in relation to a plane perpendicular to the longitudinal axis of the wagon, typically approximately 4-­10° and preferably approximately 7°, a joint such as this bears effectively any tensile and compressive stresses in the direction of the longitudinal axis of the wagon, as well as any bending stresses appearing on the plane of the side wall, without the joint notably tending to open as the load fluctuates.
  • the wedge surfaces may be flat or, for example, cylindrical surfaces, the rotation axes of which are perpendicular to the closing direction A.
  • U-shaped bows 19 installed in the frame 5 so as to protrude at its protrusion and from the frontal surface 18 of the protrusion.
  • the U-shaped portion thus extends outwards from the wedge protrusion 11, and the branches of the U-shape point towards the centre line of the wagon, and they are fixedly locked to the wagon frame 5 by using nuts 32, for example.
  • the aim is to place the bows 19 so that the plane defined by the branches 19b, 19c of a bow is parallel to the longitudinal direction of the pro­trusion 11 and the groove 12.
  • the plane de­fined by the branches of the U-shape should be located as close to the wedge surface 17 of the side wall 4 as possi­ ble.
  • the purpose of this is that the working arm of the single-arm lever 20, which is used for locking the joint, should become as short as possible in order that the moment in it would be maximal.
  • the two single-arm levers 20 shown in Figure 4 are prefera­bly placed in a position approximately parallel to the longitudinal axis of the wagon, and they consist of a tip 21, which bears on the inner arch of the bow 19 during operation, a support surface 22, which presses against a slide surface 23 in the side wall 4 and slides along it during operation, and an arm 24 and, when necessary, a handle 25.
  • the lever 20 is secured to the side wall 4 of the wagon by using, for example an axle 28, in which case the hole 29 in the lever 20 is oval so that the lever should function as a single-arm lever and not as a double-arm lever.
  • the axle 28 has no functional significance other than support.
  • the lever may, of course, be suspended from the side wall 4 in many other manners, for example by using hooks or bows.
  • the lever 20 When the joint has been tightened and the lever 20 has been turned to its final position, approximately parallel to the longitudinal axis of the wagon, the lever 20 is further locked, at the end on the side of the bow 25, to the side wall 4 by means of a cotter, a locking nut, a lock or in some other manner deemed suitable in the given case.
  • the tip 21 of the lever 20 and the slide surface 23 have been arranged to be simple to replace when­ever they are deemed to be too worn.
  • the operating position of the lever 20 can be adjusted to be suitable by means of the protrusion of the bow 19, i.e. the distance between the contact point 26 and the frontal surface 18 of the protru­sion 11.
  • This adjustment can be carried out, for example, by means of washers 31 placed between the flange parts 30 in the bow branches and the frame 5, the washers being tightened together by using nuts 32.
  • the adjusting can, of course, be carried out also in other ways, for example by means of the positions of a nut placed in the place of the flanges 30 and the washers 31 and the nut 32, in relation to the rest of the bow 19.
  • the straight surfaces 14 and 15 and the wedge surfaces 16 and 17 of the wedge-like protrusion 11 and the wedge-like groove 12 may be located in the oppo­site manner as compared with this embodiment, i.e. with the wedge surfaces towards the ends of the railway wagon and the straight surfaces towards the middle of the wagon. It can also be thought that both sides of the wedge protrusion and the wedge groove are wedge-like.
  • the structure may also be the opposite in the sense that the wedge-like groove is located in the frame 5 and the wedge-like protrusion in the side wall 4.
  • the directions and locations of the wedge sur­faces may be various, as above.
  • the bow may also be placed in either part, regardless of which part has a protrusion and which part has a groove. However, it is in general the most appropriate to ensure that the lever 20 tightens in the same direction A as is the direction of the tightening of the wedge protrusion into the wedge groove and that it is located on the outer side of the wagon, where it is easily accessible.
  • the lever arms 20 may number one, two, or more, according to the need in the given case.
  • it is possible to secure and lock some wall part by using one, two, or more locking systems 6 according to this invention, with their wedge protrusions and grooves.
