Description

The invention relates to a vehicle for loading rails, with a frame, with at least two rail-mounted bogies on the frame and with a loading device for loading the rails,

It is known to use such vehicles when laying rails. The vehicle mentioned at the beginning drives behind a rail laying vehicle on the newly laid track by the rail laying vehicle. To lay the rails, the vehicle passes the rails forward in the working direction to the rail laying vehicle driving ahead. For this purpose, the rail laying vehicle pulls the rails stored on the vehicle mentioned at the beginning into a laying position using winches or the like.

The disadvantage of the known vehicle for loading rails is that such vehicles are rail-bound. This means that they must be guided in the working direction behind the preceding rail-laying vehicle on the newly laid rail line. This requires complicated mechanics

on the rail laying vehicle, which brings the rails, which are pulled from the vehicle onto the rail laying vehicle using the winch or similar, into the working position for laying. The particular problem here is that the direction in which the rails are pulled onto the rail laying vehicle is opposite to the working direction, i.e. the direction in which the rail laying vehicle moves when laying the rails. The direction of the rails to be laid must therefore be mechanically reversed on the rail laying vehicle.

The object of the invention is therefore to design a vehicle of the type mentioned at the outset in such a way that a reduction in the mechanical effort when feeding rails to be laid onto the rail laying vehicle is possible.

The object is achieved according to the invention in a vehicle of the type mentioned at the outset in that the vehicle is designed as a two-way vehicle and has at least one lowerable crawler on the frame for moving the vehicle independently of the rails.

The advantages of the vehicle designed according to the invention are in particular that the vehicle is no longer dependent on the rails for its movement. The lowerable caterpillar for moving the vehicle independently of the rails allows the vehicle to be moved in particular on the ballast or pianum protective layer lying in front of the laying vehicle in the working direction. In this way, the rails can be moved from the vehicle onto the rail laying vehicle and laid in the direction of this movement. The vehicle according to the invention therefore makes it possible to dispense with the complex mechanics for moving the rails on the laying vehicle and reversing the direction of movement. At the same time, however, the vehicle can be equipped with rails at appropriate transfer points, since, as before, it has rail-compatible bogies for moving on rails. The vehicle according to the invention therefore represents a considerable relief and simplification of the work processes when laying rails.

It is particularly preferred that the crawler(s) be designed to be steerable. The steerable design of the crawlers enables the vehicle to negotiate curves without any problem. In a vehicle consisting of several carriages, at least one crawler is provided per carriage. Often several carriages are necessary, since the

The rails to be transported are usually 120 m long, for example. By coupling several wagons together, an area of sufficient length is created to accommodate the rails. By aligning the tracks accordingly, each individual wagon can be steered in order to be able to adapt the entire vehicle to the curve or bend to be negotiated.

In this embodiment, it is particularly advantageous that the carriages are rigidly connected to one another using adjustable hydraulic cylinders. With the help of these hydraulic cylinders, the angular position of the carriages relative to one another can be adjusted. It is particularly preferred that the tracks can be steered according to the relative angular position of the carriages. The coordinated adjustment of the hydraulic cylinders and tracks enables controlled and clean curved travel.

In a preferred embodiment of the invention, a gantry crane is provided for loading the rails. With the help of this gantry crane, which is preferably movable on a track on the vehicle and has its own drive, the rails can be loaded onto the vehicle and loaded rails can be transferred from the vehicle to the rail locking vehicle.

Alternatively or in addition, a winch can also be provided for loading the rails. In particular, as an alternative to the gantry crane, the winch is a cost-effective solution for loading the rails onto the vehicle. In such an embodiment, the transfer to the rail loading vehicle is possibly carried out by the rail loading vehicle itself. This is done, for example, by the rail laying vehicle driving so close behind the vehicle according to the invention that it can grab the rails on the vehicle and feed them to the actual laying part.

A particularly preferred embodiment of the invention is characterized by its own drive. The vehicle's own drive enables it to move independently of a towing vehicle or independently of the rail-laying vehicle. The vehicle can therefore advantageously drive independently of the rail-laying vehicle in front of it on the track that is still railless during rail-laying, i.e. move in crawler mode; however, the vehicle can also move on the rails with its own drive and, for example, go to a rail transfer point to pick up new rails. The drive is preferred here.

usually supplied by an energy station on the vehicle, which can also be used to supply all other consumers on the vehicle.

A preferred embodiment of the invention, in which the vehicle has several carriages, is characterized in that each carriage is supported on the ground at least at its ends. Such supports advantageously ensure that the gantry crane, which moves on the vehicle on the track, can move over the carriage ends without them being crushed by the weight of the gantry crane.

In another embodiment of the invention, a central support or at least two side supports, which are components of the frame, contribute to the further stability of the vehicle.

Preferably, the frame carries a platform on which rails are arranged for moving the gantry crane, i.e. for forming the travel path for the gantry crane.

Other preferred embodiments of the invention are described in the subclaims.

In the following, an embodiment of the invention will be described with reference to the drawing.

Show it:

Figure 1 a vehicle for loading rails in a

side view; and

Figure 2 the vehicle from Figure 1 seen from above, without the

Gantry crane and the platform.

Figure 1 shows a vehicle 2 for loading rails, with a frame 4, with two rail-mounted bogies 6 arranged and secured beneath the frame 4. The vehicle 2 also has a loading device designed as a gantry crane 6 for loading the rails. The vehicle 2 is designed as a two-way vehicle and for this purpose has a lowerable crawler 10 on the frame 4. The steerable crawler 10 is shown in the lowered state in Figure 1.

The gantry crane 8 has a pivotally mounted boom arm 14. A hydraulic cylinder 16 is arranged on the gantry crane 8 to pivot the boom arm 14. At the end of the boom arm 14 there is a gripping device 18 for gripping the rails to be loaded. The gantry crane 8 travels on rollers 20 on a track 22 shown in dashed lines in Figure 2, which is located on a platform 24 arranged on the frame 4. The track 22 is arranged in the longitudinal direction of the vehicle 2.

In the embodiment shown, the rail-mounted bogies 6 each have two axles, each with two wheels 6a. To move the vehicle 2 on rails, at least one of the axles of the two rail-mounted bogies 6 is equipped with a drive (not shown). The rail-mounted bogies 6 are each located at the two ends 2a of the vehicle 2, and can also contain more than two axles.

The crawler 10 has several axles, each with two support rollers 10a. At least one of the axles is provided with a drive (not shown) for the support rollers 10a. A crawler chain 10b runs around each support roller 10a. This represents the support element of the crawler 10.

The crawler 10 is attached to the frame 4 of the vehicle 2 via an arm 26. The arm 26, which is pivotally mounted on the frame 4, can be adjusted with the aid of an adjusting cylinder 28 in such a way that the crawler 10 can be pulled towards the frame 4 on the one hand and lowered towards the ground 12 on the other. The latter possibility is shown in Figure 1. By lowering the crawler 10 with the aid of the arm 26, the vehicle 2 can be raised after the part of the crawler chain 10b facing the ground 12 has contact with the ground 12. By raising the vehicle 2, the wheels 6a of the rail-mounted bogies 6 lose contact with the ground 12.

The drives of the rail-mounted bogies 6, the gantry crane 8 and the crawler 10 (not shown) are supplied with energy, for example, via an internal combustion engine 30. The engine 30 is arranged in a box 32 below the frame 4. The engine 30 receives its fuel from a tank 34 that is also arranged below the frame 4. The tank 34 is arranged in a second housing 36 that is mounted below the frame 4. The engine 30 and the tank 34 are arranged on both sides of the crawler 10 between the crawler 10 and one of the rail-mounted bogies 6.

Viewed from the crawler 10, beyond the rail-mounted bogies 6, there are supports 38 attached to the frame 4 at each end 2a of the vehicle 2. The supports 38 each have extendable plates 40. The plates 40 can be lowered to the ground 12 so that they support the vehicle 2 resting in the middle on the crawler 10 at each end 2a.

There are couplings 42 at each end 2a of the vehicle 2. Using these couplings, several vehicles 2 can be connected in series.

Adjustment cylinders 44 are arranged beneath the couplings 42, adjacent to the supports 38. These adjustment cylinders 44, which are arranged beneath the corners of the platform 24, as can be seen from Figure 2, are connected to further adjustment cylinders when several vehicles 2 are coupled together using the couplings 42. The angle of the longitudinal axes of the vehicles 2 relative to one another can then be adjusted using the connected adjustment cylinders 44. This is done, for example, by extending the adjustment cylinders 44b on one side of the vehicle 2, while the adjustment cylinders 44a on the other side are retracted. In this way, the vehicles 2 are then pivoted relative to one another about an axis running vertically through the couplings 42 and can therefore make curved journeys.

Figure 2 shows the vehicle of Figure 1 without the gantry crane 8 and with the platform 24 raised. Figure 2 shows the longitudinal direction of the vehicle 2, with supports 4a extending from the ends of the vehicle 2 to reinforce the frame 4. The centrally running supports 4a end in the middle of the vehicle 2 at cross supports 4b arranged to the left and right adjacent to the crawler 10 and running transversely to the supports 4a. The cross supports 4b each extend from one side 2c of the vehicle 2 to the other side 2d. Between the T-shaped support arrangements formed from the supports 4a and 4b, a support-free space corresponding to the dimensions of the crawler 10 remains below the platform 24, which is only limited by the frame 4 to the sides of the vehicle 2.
