Abstract
An anchoring device mechanism for anchoring rails includes a plurality of clamping jaws. The clamping jaws are connected to a jaw displacement device in order for the clamping jaws to be moved from a rail clamping position into a rail releasing position. A clamping drive unit is provided for moving the clamping jaws into the rail clamping position.
Description
- The invention relates to a rail loading train for the transport of long-welded rails, including loading cars mobile on a track and an anchoring device for the rails which is arranged at the end of the loading train and has clamping jaws comprising in each case a rail contact surface for force-locking application to a rail.
- Rail loading trains of this type are already known from WO 2007/065500 A1 or EP 2 427 599. A device for anchoring the rails consists of a number of insertion devices. The latter has two clamping jaws, each with a movable roller-shaped clamping means. For force-locking connection of the clamping means to the rail base or for releasing the connection, the two clamping jaws are designed to be spaced to and from one another.
- It is the object of the present invention to provide a rail loading train of the kind mentioned at the beginning with which the clamping, necessary for the transport, of the long rails to be transported can be carried out with optimal clamping reliability.
- According to the invention, this object is achieved with a rail loading train of the kind mentioned at the beginning by way of the features cited in the characterizing part of
claim 1. - Due to this combination of features, an automatically executable clamping of the rails with high clamping power can be achieved. Additionally, a problem-free and likewise automatic release of the rails for the unloading of the same from the rail loading train is ensured.
- Further advantages of the invention become apparent from the dependent claims and the drawing description.
- The invention will be described in more detail below with reference to an embodiment represented in the drawing.
FIG. 1 shows a simplified side view of a rail loading train,FIG. 2 shows a top view of an anchoring device provided for the clamping of rails,FIG. 3 shows an enlarged partial view of the anchoring device, andFIGS. 4, 5 each show an enlarged schematic cross-section of the anchoring device. - A
rail loading train 1, shown inFIG. 1 , is composed of a number ofloading cars 4, mobile via on-track trucks 2 on atrack 3, and serves for the transport of long-weldedrails 5. In a known manner, these are stored onswivel beams 6 in three layers arranged one above the other. For loading and unloading therails 5, acrane 7 is provided which is freely mobile along theloading cars 4 on crane rails and which displaces the long-weldedrails 5 in the longitudinal direction of the car or train. At the end of therail loading train 1, ananchoring device 8 for anchoring therails 5 during transport is located. - As can be seen
FIGS. 2 to 5 , theanchoring device 8 comprises a number ofclamping jaws 10 which are arranged parallel to one another and are displaceable in ajaw displacement direction 9 and have a jawlongitudinal direction 11 extending perpendicular to thejaw displacement direction 9. Theclamping jaws 10 arranged on thecommon anchoring device 8 are connected with the aid of ajaw displacement device 12 for displacement of theclamping jaws 10 from a rail clamping position into a rail releasing position. Aclamping drive 13 is provided for shifting theclamping jaws 10 back into the rail clamping position. Saidclamping drive 13 is equipped with a hydraulic safety clamping, by means of which the clamping effect for fixing therails 5 is maintained unrestricted even in the event of an energy failure or malfunctions. - Each
clamping jaw 10 has tworail contact surfaces 14, extending parallel to one another in the jawlongitudinal direction 11 and lying opposite one another with regard to thejaw displacement direction 9, which are designed in each case for accommodating an end region of arail base 15 of arail 5. Eachclamping jaw 10 is connected to a railbase contact plate 16 provided for support of therail 5. Said railbase contact plate 16 extends in each case from therail contact surface 14 in the direction towards theadjacent clamping jaw 10. Therail contact surfaces 14 and the railbase contact plates 16 have a special coating for increasing the friction value. - As can be seen in
FIGS. 4 and 2 , theanchoring device 8 or rather aswivel beam plate 17 has twoguide channels 18 which extend parallel to one another and are spaced from one another with regard to the jawlongitudinal direction 11. Arranged in these channels are guidingwedges 19 which are displaceable in thejaw displacement direction 9 and connected in each case to a clampingjaw 10. Each guidingwedge 19 has two clampingshoulders 21 spaced from one another in the jawlongitudinal direction 11 and provided for application to an underside of theswivel beam plate 17. - The mode of operation of the
anchoring device 8 will be described in more detail below. - For setting down
rails 5 to be transported, theadjacent clamping jaws 10 are spaced from one another in each case in such a manner that a problem-free placement of therail base 15 on the twosliding strips 20 is possible. The displacement, required for this purpose, of theclamping jaws 10 into the respective rail releasing position takes place by means of thejaw displacement device 12. - During this rail loading operation, each
clamping jaw 10 rests on thesliding strips 20 which are spaced from one another in the jawlongitudinal direction 11 and connected to theswivel beam plate 17 and extend parallel to one another (see right-hand part ofFIG. 4 ). In this state, the railbase contact plates 16 connected to theclamping jaws 10 are lowered slightly with respect to asliding plane 22, formed by the sliding surface of thesliding strips 20, in such a way that no contact exists between therail base 15 and railbase contact plates 16 during the rail loading. As a result, the guidingwedges 19, connected to theclamping jaws 10 and the railbase contact plates 16, are also lowered slightly in such a manner that there is no contact of the clampingshoulders 21 with the underside of the swivel beam plate 17 (seeFIG. 4 ). - After termination of the rail loading operation, the
clamping jaws 10 are moved towards one another in pairs with the aid of theclamping drive 13, whereby finally a contacting of the rail base end with the associatedrail contact surface 14 takes place. Immediately prior to finishing this closing operation, there is a slight lifting of theclamping jaws 10 together with the connected railbase contact plates 16 and the guidingwedges 19 due to the wedging effect of therail contact surfaces 14 with the rail base end (seeFIG. 5 ). - This finally leads to an intensive frictional locking both between the
rail base 15 and therail contact plate 16 as well as between the clampingshoulders 21 of the guidingwedges 19 and theswivel beam plate 17. The resulting frictional lock can be additionally enforced by a special laser coating. - If not all of the clamping positions of the
automatic anchoring device 8 are occupied, the hydraulic clamping force produced by theclamping drive 13 is transmitted via the adjoiningrail contact plates 16. - In order to avoid an uncontrolled slipping of the
rails 5 when opening theanchoring device 8 in a track incline, electromagnets are arranged in theswivel beam 6. These absorb the downward shear force of therespective rail 5 and produce a magnetic force acting against an uncontrolled slipping of the rail. The respective magnet is unlocked only when the respective rail is seized by the gripper of therail crane 8. - With the aid of the electromagnets associated with each rail, all rails can now be released separately in any desired order and subsequently be pulled off the loading car by the crane. For this purpose, the second clamping position for example is released in that the respective neodymium magnet is demagnetized and sinks downward and thus removes the friction coating from the underside of the long rails. Thereafter, the rail can be pulled off with low friction.
