Description

An intermediate layer for height spacing is provided

  and the support of long rails extending perpendicular to the intermediate layer during their transport on rail loading wagons, with a rail bearing surface provided for the support of long rails as well as a loading train

  rails for the use of intermediate layers.

  Long rails which are transported on normal loading wagons lie for their spacing in height and their support on intermediate wooden layers. Therefore, by the relatively high friction value between the rail and the intermediate layer, safe transport is ensured. However, the high friction value has the disadvantage that for the removal of long rails, tensile forces

  particularly high are necessary.

  A rail loading wagon specially produced for the transport of long rails is known from document DE 44 18 376 A1. In these loading wagons, the intermediate layers are produced in the form of rail bearing surfaces pivotally housed on the wagon chassis which, in order to obtain a particularly reduced friction value, are equipped with rollers on which the rails rest.

long.

  However, the subject of the present invention is the creation of an intermediate layer of the type indicated at the start which allows removal of long rails by means of a force.

reduced traction.

  This object is achieved in accordance with the invention by means of an intermediate layer of the type indicated at the start, in that the intermediate layer has two rail bearing surfaces with a different friction value for supporting the long rails which are made displaceable in height, one relatively to the other using a

height adjustment.

  Such an intermediate layer has the advantage that the friction value can be adapted from a

  optimally to the respective work situation.

  While the first rail bearing surface having a high friction value ensures safe transport without any limitation, the friction value, by lowering the above-mentioned first rail bearing surface can be reduced to lie below the level of the second rail bearing surface for problem-free removal of long rails. This lowering movement takes place in this case in an appropriate manner automatically under the effect of the weight of the long rails resting on the first rail bearing surface which makes it possible to reduce the constructive expense for the intermediate layer in two parts conforming to the invention to a minimum. According to another characteristic of the invention, the first rail bearing surface is made of wood and

  the second steel rail bearing surface.

  According to yet another characteristic of the invention, the first rail bearing surface, preferably made of wood and of a rectangular cross section is housed on the second steel rail bearing surface of a cross section in According to another characteristic of the invention, it is arranged between a base surface connecting two side walls extending parallel to each other of the second rail bearing surface and a lower side of the first rail bearing surface, the height adjustment device in the form of a number of double corners positioned one behind the other in the longitudinal direction of the intermediate layer, respectively two corners being arranged one at the -above the other with a contact of their two conical surfaces and are movable against each other in the longitudinal direction of the

middle layer.

  According to yet another characteristic of the invention, the upper ends of the side walls extending parallel to the base surface can be used as a rail contact surface, the height of the side walls being greater than the

  height of the first rail bearing surface.

  According to yet another characteristic of the invention, a conical angle of each corner represents

about 10 to 250.

  According to yet another characteristic of the invention, the lower corner of each double corner is connected to the base surface of the second rail bearing surface and the associated upper corner is connected to a steel trough in which is housed the first surface

rail support.

  According to yet another characteristic of the invention, there is provided at a longitudinal end of the second rail bearing surface a transverse displacement device for the transverse displacement of the first rail bearing surface relative to the

second rail bearing surface.

  According to yet another characteristic of the invention, the transverse displacement device is produced in eccentric form which is rotatably housed around a shaft extending perpendicular to the side walls and which has

  a rotating safety locking element.

  According to yet another characteristic of the invention, rollers, as a second rail bearing surface are fixed to the free upper ends of the side walls and which are respectively rotatably housed around axes extending parallel to the base surface and in direction

  longitudinal of the intermediate layer.

  The invention also relates to a rail loading train with a number of rail loading wagons, supported on undercarriages on rails, coupled to each other for the transport of long rails extending in the longitudinal direction. of the train which, in a layer, are arranged in the transverse direction of the rails one

  next to each other and are stacked in layers one above the other

  above each other, the different layers being spaced from each other by a multitude of intermediate layers arranged in the longitudinal direction of the train one behind the other, extending perpendicular to the long rails which respectively have a rail bearing surface for bringing each long rail into contact with a shoe, characterized in that the intermediate layer has two rail support surfaces with a different friction value, where the two rail support surfaces are adjustable in height relative to each other by a

height adjustment device.

  The invention will be better understood and other aims, characteristics, details and advantages thereof

  will appear more clearly during the description

  Explanatory which will follow made with reference to the accompanying schematic drawings given solely by way of example illustrating embodiments of the invention and in which: - Figure 1 is a partial view in cross section of a rail loading train simply sketched, loaded with long rails, o the different horizontal layers of the long rails are spaced from each other respectively by intermediate layers according to the invention; Figure 2 is an enlarged view of the intermediate layer in the longitudinal direction thereof, along the section line II in Figure 3; - Figure 3 is a longitudinal view, in cross section of the intermediate layer along the section line III in Figure 2; and - Figures 4 and 5 are schematic views of another embodiment of a layer

  intermediate produced in accordance with the invention.

  On a rail loading wagon 1 simply sketched for clarity of a rail loading train 2 consisting of several of these wagons are long rails 4 extending in the longitudinal direction of the wagon and arranged parallel to each other

  next to the others by forming a horizontal layer 3.

  Each layer 3 of the long rails 4 is supported on a multitude of intermediate layers 5 extending perpendicular to the long rails 4 which are spaced from each other in the longitudinal direction of the rails. The intermediate layer 5 consists respectively of a first rail bearing surface 6 preferably made of wood and of a second surface

  rail support 7 preferably made of steel.

  Relative to the vertical line, there is between these two rail bearing surfaces 6, 7 a height adjustment device 8 in the form of a number of double corners 9 spaced from each other in the

  longitudinal direction of the intermediate layer 5.

  As seen in particular in FIGS. 2 and 3, the first rail support surface 6, preferably made of wood and of a rectangular cross section is housed on the second rail support surface 7 of steel, d 'a U-shaped cross section. This second rail bearing surface 7 has two side walls 10 extending parallel to each other and in the longitudinal direction of the intermediate layer 5 as well as a surface of base 11 connecting these. A lower corner 12 of each double corner 9 is connected to the base surface 11 of the second rail support surface 7 while an associated upper corner 13 is connected to a U-shaped steel trough 14 in

  which is housed the first rail support surface 6.

  The two corners 12, 13, with a contact of their two conical surfaces 15, are respectively arranged one above the other and are movable against each other in the longitudinal direction of the intermediate layer by changing their position in height. A conical angle α formed by the conical surface 15 and the vertical is approximately 10 to 25, it is preferably

of 210.

  As seen in particular in FIG. 2, the upper ends of the side walls 10 extending parallel to the base surface 11 can be used as rail contact surface 16 for the support of the long rails 4. In this case it is essential that the height of the side walls 10 of the second rail bearing surface 7 be greater than the height

  of the first rail bearing surface 6.

  At a longitudinal end of each intermediate layer 5 is a transverse displacement device 17. This consists of two eccentrics 18 which are rotatably housed on a shaft 19 extending perpendicular to the walls

  lateral 10 and parallel to the base surface 11.

  The shaft 19 itself is housed on the second rail bearing surface 7 and can be rotated by hand using a lever 20 of 180. For the rotational locking for the downfoot travel there is provided a rotational safety locking element 21 in the form of a bolt 22 which can be inserted through corresponding holes in the side walls 10 and the two eccentrics 18. At the end of the second rail bearing surface 7 opposite the rotational safety blocking element 21 there is provided a front wall 29 connected to the base surface 11 and to the side walls 10 (FIG. 1 ) to limit movement

  transverse of the first rail bearing surface 6.

  The mode of

  functioning of the intermediate layer 5.

  The long rails 4 are deposited by the manufacturer in layers on the intermediate layers 5, o respectively the first rail bearing surfaces 6

  wooden in their upper final position.

  In this position, a rail contact surface 23 for the support of the long rails 4 is located above the two rail contact surfaces 16 of the second rail support surface 7. The rotational safety 21 is activated by the insertion of the bolt 22 so that during transport there is no mutual displacement in height of the two rail bearing surfaces 6, 7. Thus, during transport, all the long rails 4 rest on the first wooden rail 6 bearing surfaces which have

  a higher friction value.

  With a view to removing the long rails 4 on the site, first of all, only for the intermediate layers 5 supporting the upper layer 3 is the lowering of the first rail bearing surface 6. To this end, the lever 20 is moved slightly in the direction shown by an arrow 24 whereby the bolt 22 is unloaded and can thus be pushed out of the eccentrics 18 and the side walls 10. Then, by repeatedly actuating the lever 20, it is caused a rotation of the eccentric 18 causing a sliding towards the side from the upper corners 13 to the lower corners 12 and consequently a lowering of the first rail bearing surface 6 under the action of the weight of the long rails 4 resting on the surface of rail contact 23. When the lowering movement is complete, the rail contact surface 23 of the first rail support surface 6 is located below the rail contact surfaces 16 of the two xth rail bearing surface 7 so that the long rails now rest on the rail contact surfaces 16 of the second rail bearing surface 7. Due to the resulting lower friction value, the long rails 4 can be easily removed from the rail loading wagon 1. Alternatively, to further reduce the friction value, the rail contact surface 16 of the second rail bearing surface 7 could also be provided under the shape of a multitude of contact rollers arranged one behind the other in the longitudinal direction of the intermediate layer 5

(see figures 4 and 5).

  In the embodiment of an intermediate layer 5 shown in Figures 4 and 5, for simplicity, the parts having the same function are designated by the same reference numerals as in the case of the first embodiment. At the upper free ends of the side walls 10, to form the second rail bearing surface 7, rollers 25 are fixed which are respectively housed in a rotary manner around axes 26 extending parallel to the base surface 11 and in the

  longitudinal direction of the middle layer 5.

  As a height adjustment device 8, two hydraulic pipes 27 are provided, filled with hydraulic oil, between the base surface 11 of the second rail bearing surface 7 and the first rail bearing surface 6. At the front end of the second rail bearing surface 7, it is positioned a hydraulic valve 28 with a small oil tank. To lower the rail contact surface 23 under the rollers 25, it suffices to open the hydraulic valve 28 which results in a partial draining of the hydraulic pipes 27 and a

  lowering of the first rail support surface 6.

  To raise the first support surface of rail 6, a few pump movements are enough to fill the

  hydraulic hoses 27 in hydraulic fluid.
