And a gripper mechanism disposed on the rail loading crane for gripping the long rail and capable of being adjusted vertically and horizontally by a drive device, for loading the long rail. About getting off car.

[0002]

[Prior art]

 Rail-loading vehicles of the above-mentioned type are already known from DE-A-27 34 748, which consist of a rail knitted from a plurality of vehicles when viewed in the rail extension direction. It is located at the front end of the transport train. Two rail loading cranes can travel along the rails that extend in the vehicle longitudinal direction of the rail loading / unloading vehicle, and each rail loading crane can be adjusted vertically and horizontally to grip one long rail. Each has a possible gripper mechanism. Although the pull-out force is certainly increased by arranging two rail loading cranes, the increase of the pull-out force is limited by the limitation of the axle load.

[0003] A rail loading / unloading vehicle in which a rail loading crane provided with a gripper mechanism for gripping a long rail can travel on the vehicle is also known from German Patent 1,208,326. Has become. The long rail is supported on a rail cradle in the area of the transport wagon, the rail cradle supporting the long rail from an operating position extending laterally of the vehicle to a non-operating position extending longitudinally of the vehicle. Can turn. In order to reduce the pull-out force required for pulling out the long rail, the rail support has rollers for supporting the long rail.

[0004] Furthermore, another rail unloading vehicle is known from German Utility Model No. 29701016, in which a rail loading crane extends in the longitudinal direction of the vehicle. And is configured as a crane carriage which is engaged and supported by a guide connected to the vehicle frame. The crane carriage is configured to be shiftable in the longitudinal direction by a shift drive device for transmitting power in an engagement connection manner, and is connected to a gripper mechanism for gripping a long rail to be drawn. A significantly higher tensile force can be generated by the engagement-type power transmission, so that a long rail supported only by an intermediate sandwich between the rail layers can be drawn out.

[0005]

[Problems to be solved by the invention]

 By the way, the problem of the present invention is to improve the rail loading vehicle of the type mentioned at the beginning so that the structural cost can be minimized and the pulling force required to pull out the long rail can be increased. Is to configure.

[0006]

[Means for Solving the Problems]

 According to a first aspect of the present invention, there is provided a cable winch having a tension cable capable of extending a cable end, and a cable joint having a variable length by winding up a vehicle frame. To be formed between the rail loading crane and the vehicle frame.

[0007] Due to the above configuration of the present invention, it is possible to achieve a significant increase in the pull-out force, independent of the adhesive friction action between the rail loading crane and the rail. Therefore, particularly long rails that require particularly high pull-out force because they are only placed on the intermediate sandwiching tree can be drawn out without any problem. The particular advantage in this case is that structural over-costs are minimized and that the retrofitting of a rail loader that is already in use is relatively easy.

[0008] Other advantageous features of the invention are evident from the claims and the detailed description of the drawings.

[Embodiment of the invention]

 Next, an embodiment of the present invention will be described in detail with reference to the drawings.

A rail unloader 1 partially shown in each of FIGS. 1 to 6 is composed of two loaded vehicles 4 connected to each other by a connector 2 and supported on a rail traveling vehicle 3, respectively. Have been. Each loading vehicle 4 has a vehicle frame 6 extending in the longitudinal direction of the track 5 and two inner rails 7 for running the rail loading crane 8. At the front end of the rail loading crane 8 as viewed in the rail pull-out direction (arrow 9), two grippers are disposed at an interval in the vehicle lateral direction and can be adjusted vertically and horizontally by the drive unit 10. A mechanism 11 is provided for gripping the long rail 12. Furthermore, the rail loading crane 8 is equipped with an operator cab 14 (see FIG. 3) in which a control device 13 is mounted and a drive device 15 (see FIG. 5).

A cable winch 16 is fixedly mounted at the front end of the rail loading crane 8 when viewed in the rail pull-out direction (arrow 9), and the cable winch is driven by a driving device 17 at right angles to the longitudinal direction of the vehicle. It is configured to be rotatable about a horizontally extending axis. From the cable winch 16, a tension cable 18 forming a first cable joint 26 can be extended or wound up by the cable winch, and the tension cable 18 can be connected to a deflection cable provided at the front end of the loading vehicle 4. It is deflected around a guide roller 19 (see FIG. 5), and the cable end 20 (see FIG. 6) of the pull cable is fixed to the rail loading crane 8. The deflection guide roller 19 is rotatably supported by the vehicle frame 6 about a vertical axis 21.

A cable 24 forming a second cable joint 23 is fixed to a rear end 22 of the rail loading crane 8 as viewed in the rail pulling-out direction (arrow 9), and the rear end of the cable is , Can be engaged and connected with the long rail 12 to be pulled out by the quick chuck mechanism 25. In order to pull out the two long rails 12 at the same time, two cables 24 each having its own quick chuck mechanism 25 are provided at intervals in the lateral direction of the vehicle. In particular, as can be seen from FIG. 1, the front section 31 of the long rail 12 loaded on the transport vehicle 27 connected to the rear of the rail unloader 1 is separated from the adjacent rail unloader 1, namely The long rail 12 can be elastically bent because it is separated from the loading vehicle 4 at the top. The long rails 12 are separated from each other by an intermediate clip 28 for each layer.

Next, the function of the rail loading vehicle 1 according to the present invention will be described in detail.

The cable end 20 of the pull cable 18 unwound from the cable winch 16 of the rail loading crane 8 and diverted over the deflection guide rollers 19 is connected to the rail loading crane 8 to form a first cable joint 26. Is linked to In this case, the rail loading crane 8 is located at the rear end position of the rear end of the rail unloading vehicle 1 as viewed in the rail pull-out direction (arrow 9) (see FIGS. 1 and 2). The second cable joint 23 formed by the rear cable 24 is engaged with the two long rails 12 to be withdrawn via two quick chuck mechanisms 25.

In order to start the pulling-out operation, the driving device 17 is supplied with a pressure, and the tension cable 18 is wound around the cable winch 16 according to the supplied pressure, whereby the rail loading crane 8 is gripped by the quick chuck mechanism 25. Together with the two long rails 12 thus drawn, they are pulled in the rail pull-out direction (arrow 9) (FIGS. 1 and 2).

As soon as the front section 31 of the extended long rail 12 is located in the region of the coupling 2 (see FIGS. 3 and 4), the drive 17 of the cable winch 16 is switched to pressureless and the rail The loading crane 8 travels back to the starting position at the rear by the driving device 15 in a direction opposite to the rail pull-out direction. In this case, since the rail loading crane 8 is configured in a gate-shaped frame structure, the rail loading crane 8 can travel back beyond the front section 31 of the long rail 12 without any problem. As soon as the rail loading crane 8 reaches the rear end position, the front sections 31 of both long rails 12 are gripped by the gripper mechanism 11 of the rail loading crane 8. At the same time, behind the rail loading crane 8, an engagement connection with two long row rails 12 is formed via two quick chuck mechanisms 25. The drive 17 of the cable winch 16 is then subjected to a feed pressure, so that the rail loading crane 8 is moved together with the long rail 12 gripped by the gripper mechanism 11 and also by the quick chuck mechanism 25 in the rail pull-out direction. (See FIGS. 3 and 4).

As soon as the front section 31 of the two long rails 12 reaches the loading vehicle 4 in the front position, the front section 31 is introduced and lowered into the rail vertical guide 30 by the supply pressure load of the driving device 10 (FIG. 5). And FIG. 6). A plurality of deflection guide rollers 29 provided in the region of the coupling 2 and rotatable about a vertical axis serve to guide the long rail 12 to be drawn out laterally. As soon as the front ends of the two long rails 12 contact the track 5, a detachable connection with the track is made. The gripper mechanism 11 and the quick chuck mechanism 25 are disengaged from the long rail 12. Subsequently, the longrail is withdrawn from the transport vehicle 27 by the forward movement of the rail unloader 1 and the transport vehicle 27 by the locomotive not shown.

The cable winch 16 can be fixed to the vehicle frame 6 instead of the deflection guide roller 19.
