Description

Railway units with pivotable load-bearing structures for combined rail/road transport of semi-trailers or two motor vehicles

technical field

The present invention relates to a railroad unit for combined rail/road transport with a pivotable load bearing structure detachable from an end member at at least one end so as to assume a loaded and unloaded inclined position.

In particular, the invention relates to a pivotable railway load-carrying structure equipped with a pivotable support which can be loaded, transported and then unloaded with half a trailer and two motor vehicles on the same railway installation without modification thereof .

Background technique

In the prior art, in the semi-trailer railway/highway combined transport mode, the tractor is used to load the semi-trailer on the load-bearing structure of the railway in order to reduce the weight of the equipment.

This technology disengages the truck along a loading and unloading inclined position where the semi-trailer is guided or lifted by its tractor.

For dimensions and operational reasons, after loading the tractor is decoupled from the semi-trailer and remains in this position or is transported separately on the same train of the rail/road combination.

While technically the semi-trailer is compatible with other semi-trailer tractors, semi-trailers transported by rail do not always belong to large businesses with large numbers of tractors at their destinations.

For this reason and for the economically imperative simplification, it has proven to be advantageous to transport the tractor originally assigned to the semi-trailer on the same train.

Not only that, but in some cases only a portion of the total mileage is handled by these trains in between. The tow vehicle must be transported with its tow vehicle for this part of the mileage.

Only the above-mentioned railway installation for transporting semi-trailers is included in the new technology related to the present invention. For economical, technical and regulatory reasons, these railway installations have only a finite length. They are constructed in such a way that the front overhang of the semi-trailer is cantilevered to one of the end swivel blocks of the railroad. For this reason, the loading capacity of this rail installation is designed to transport exactly one half of the trailer. Thus, the length of the two tractors of the semi-trailer exceeds the length of the load-bearing base of the pivotable railway load-bearing structure and thus cannot be transported simultaneously in this type of wagon. When semi-trailer road trailers have to be transported in these vans, we can only transport them one at a time.

This solution is completely uneconomical. It conflicts with the ability to optimize the operation of carriages and rail installations.

The tractors may also be transported on another part of the train with freight cars specially designed to accommodate the tractors. This composition is unsatisfactory due to the incompatibility of the railway installation and the railway train formation to be managed.

Not only that, the remoteness of the tractor and its semi-trailer results in a waste of time and a lot of energy during the loading and unloading phases.

This distance especially complicates the re-articulated assembly of the road vehicle as a whole at the end point.

Contents of the invention

The object of the present invention is to selectively load, unload and transport two motor-tractors or half-trailers on the same rail installation intended for combined rail/road transport carrying half-trailers.

Its other purpose is to facilitate the loading and unloading of two types of road loads, which occupy the swingable support when it is placed on the ground, for the positioning function of the tractor to precisely position the introduced road load , or to position the tractor in the loading position when the tractor itself constitutes a road load.

This position in particular reduces any risk of disturbing the railway arrangement when it returns to a straight line.

Another object of the present invention is to be able to ensure that the trailer is in good position when half the trailer is loaded and this positioning is prior to the closed pivoting of the railway.

Thanks to the invention, a rail carrier or carrier rail subassembly intended to transport one semi-trailer at a time as part of the same articulated rail assembly can accommodate and transport two motor vehicles at a time, in particular two tractors of a semi-trailer And it's on the same rail base that holds half the trailer.

Therefore, the railway transport device of this railway/highway combined transport becomes dual-functional, which simplifies the management of the railway transport plan in use, and is beneficial to deal with the utilization rate of railway equipment, the combination of trains and the process of loading and unloading.

In particular, each rail unit is either stand-alone or part of an articulated assembly having a load-bearing rail structure that accommodates one half of the trailer. But there is also the option of accommodating two tractors placed next to each other, neither using particularly difficult techniques nor requiring the use of special devices for transporting motor vehicles.

But the management and operation of combined rail/road transport equipment for the overall transport of a given road load has clearly improved.

Not only that, thanks to the invention, the operations of loading and unloading can remain faster, easier, more accurate and at the same time safer.

The main feature of the present invention involves a pivotable support mounted at one end of the railway load-carrying structure for receiving the rear wheels of a tractor placed at its end and sufficiently inclined to transport two tractors.

The safety of the vertical movement distance of the kingpin of the trailer turntable is ensured by an independent mechanism arranged on the end structure of the railway device, or by a combined device for supporting and lifting swingable support, which moves together with it.

Detailed ways

The present invention relates to a railway unit 1 of wagon type for use in combined rail/road transport for the selective transport of half-trailers 2 or two road vehicles, in particular of the tractor 3 or 4 type of half-trailer.

The rail transport device 1 may be of any type as long as it is initially in an inclined position relative to the rails for loading and unloading.

The rail transport unit can be placed and individually positioned between two end rolling assemblies 5 or 6 comprising one or more axles 7 or 8 or as part of an articulated assembly for combined rail/road transport, e.g. A double wagon 9 is shown in FIGS. 1 and 3 .

The railway unit 1 of this combined railway/road transport is a unit 10 of the railway construction type, which supports the road load, in particular the half-trailer 2, and is raised or displaced, for example in rotation about a central axis, so that Inclined one position for loading and unloading.

According to the present invention it has been found that such a railway load bearing structure 10 for road loads can suitably maintain its original transport function of half a trailer by means of different arrangements and arrangements, and can also transport two motor vehicles, for example two tractors for a semi-trailer 3 and 4, thus bringing a mixed use function to the railway unit 1 such as wagons in relation to the performance of transport road loads.

The railway transportation device 1 according to the invention has been described in the previous application of the same applicant, and according to one embodiment the device comprises the following main mechanisms.

A railway load bearing structure 10 for road load rests by its ends 11 and 12 on rolling assemblies 5 and 6 having two ends of one or more axles such as 7 and 8 .

It can for example be lifted or displaced in rotation about a central or eccentric axis to one end, or in other embodiments including other means in an inclined position.

According to this example, the pivoting opening can take place on only one or two ends, one being the front connection end 11 and the other being the rear connection end 12 .

The load-bearing structure 10 of the railway is separated by at least one of its ends 11 or 12 from at least one rolling assembly 5 or 6 of the end, which end rolling assemblies are connected to each other by fitting means and openable locking means 13 or 14. for assembly.

The separation is preferably achieved by a lifting movement followed by a pivoting movement inclined relative to the longitudinal axis of the railway installation, the pivoting movement being carried out by means of a lifting-rotating mechanized device, for example, Rotatable all the way to an inclined position for loading and unloading, wherein at least one interface end 11 or 12 of the load-carrying structure 10 of the railway is in contact with the ground of the platform, or with another combined rotating mechanization within or embedded in the platform , such as a base or access ramp, or other intermediate connection or spanning structure.

The load-carrying structures 10 of these railways are used to transport motorized road loads or to support thereon their own road power units which can be separated from the road loads.

The present example is that half of the trailer 2 enters the interior of the load-bearing structure 10 of the railway with its road tractor 3 or 4, which pushes or pulls during maneuvering.

A device for limiting the play gap of the turntable kingpin for parallel protection purposes during transportation can be provided on the rolling assembly 5 or 6 at least one end.

The object of the present invention is to improve such a railway installation 1 in such a way that the installation, especially suitable for transporting semi-trailers 2, can selectively accommodate road loads to be transported, i.e. two motor vehicles, in particular two vehicles of the type semi-trailer 2. Heavy tractors 3 and 4. The tractors 3 and 4 are arranged one behind the other on the bottom of the load-bearing structure 10 of the railway, not embedded in the bearing surface of the pivotable railway structure 10 . According to the invention, one of the tractors 4 is raised in order to obtain the overall cargo length, so that the two tractors of the semi-trailer 2 placed next to each other can be transported.

For this reason and in accordance with the present invention, the pivotable railway load-carrying structure 10 is mounted at least at one end 11 or 12 with a lockable bearing 16 that supports or is movably held between two positions, which Two positions one for loading and unloading and one for transport with fixed load function, this device is used both in the case of transporting half trailer 2 and in the case of transporting two tractors of semi-trailer.

This device 16, for example made in the form of a swingable support 17, can raise the rear of the second tractor vehicle high enough to be able to load the two tractor vehicles on the same railway intended for transporting a semi-trailer 2 1 and due to this raised position, the following tractor 4 is on a part of the rolling assembly 5 or 6 at the respective end.

The arrangement also avoids any interference between the road load and the end assembly 5 or 6 when the pivotable railway load-bearing structure 10 returns to its rectilinear shape.

When engaged on the railway installation, the device can also be used to de-locate the position of the semi-trailer or an other vehicle, which acts as a positioning device. The swingable support 17 is actuated eg by an external device such as a jack, or by other non-loading means such as the loading base or access ramp 15 as part of the platform installation, or any other equivalent means.

Consideration may be given to loading lifting devices and corresponding power units.

As indicated, the pivotable support 17 also serves as a location for the road load when it is in place during the loading phase.

Below we will describe in detail the basic scheme of the railway installation according to the invention.

The pivotable railway load-bearing structure 10 comprises at least one access end 11 or 12, a support or holding device 16 in the form of an articulatedly mounted, pivotable support 17, for example on the pivotable railway load-bearing structure 10 Turn, for example, each edge stringer along the upper part of the side member.

For the sake of clarity, the axes of rotation are represented schematically by their shown geometry.

The pivotable support 17 consists of two pivotably mounted pivoting arms 18 and 19, which are pivotable through one end about an axis perpendicular to the longitudinal axis of the pivotable railway load-carrying structure 10, which For example by edge support on its side members. These arms 18 and 19 support a transverse structure, for example continuous or discontinuous supports 22 , in a pivoting or non-rotating manner, like a table, that is to say around end axes 20 and 21 or other parts perpendicular to the arms 18 and 19 .

As will be described below, the transverse structure 22 does not have to be a carrier.

Said arms 18 and 19 are secured by a locking device (not shown) in the raised support position.

In the continuous construction embodiment, the two arms 18 and 19 are connected together by a continuous supporting transverse structure 22 between them.

In an embodiment of a discontinuous structure, two separate pivotable supports are involved, extending inwardly of a length sufficient to catch at least one wheel on each side of the rear axle of a tractor being transported in a raised position.

The transverse structure of this continuous support 22 consists of two transverse members 23 and 24, for example tubular, parallel to each other, approaching in the center, and connected by a support and holding plate 25, which is formed as two parallel plates 26 and 27 , two parallel plates 26 and 27 define a central opening or receiving cavity 28 and are substantially bounded by a retaining perimeter 29 for accommodating the pivot or kingpin 30 of the semi-trailer being transported.

The cavity 28 ensures in particular the maintenance and fixation of the load against lateral forces.

The transverse tubular members 23 and 24 are separated in the vicinity of the edge of the railway's load-bearing structure 10 in such a way that a receiving and stop opening 31 and 32 is formed on each side between them, wherein they can be inserted and fixed in The respective rear wheels 33 or 34 of the rear axle 35 of the tractor 4 are transported in raised position. When the two rear wheels 33 and 34 are inserted into the openings of the respective blocks 31 and 32, the rear axle assembly of the tractor 4 is held sufficiently fixed by the wedging positioning to be lifted and stabilized in the transport position.

In both examples, this transverse support structure 22 is mainly used for road loads, ie for transporting the half-trailer on the one hand and the two tractors 3 and 4 of the semi-trailer 2 on the other hand.

In this first example, the transverse support structure 22 of the pivotable support 17 is attached to the center of the front lower surface 36 of the semi-trailer, for example under the action of an external motor of the railway installation 1, thus forming a A first fixed, and preferably combined with the brackets 37 and 38 of the semi-trailer 2 as described. When each rear wheel 33 and 34 of the tractor 4 is between the transverse members 23 and 24 of the transverse support structure 22 , the transverse line of the semi-trailer 2 passing through the king pin 30 of the trailer turntable passes through the swingable support 17 The arc 39 drawn by the ends of each of the arms 18 and 19, when the operation of introducing the semi-trailer 2 into the pivotable railway load-bearing structure 10, the pivotable railway The bearing structure 10 is on the ground as shown in FIG. 17 , and the swingable support 17 can play a positioning role.

According to a variant, once the semi-trailer is secured, we can unload the supports 37 and 38 since the transverse support structure 22 will be pressed against the stop or support of the lower front surface 36 of the semi-trailer.

According to another variant, the brackets 37 and 38 mainly ensure the support of the semi-trailer, so that the carrier plate 25 only assumes the actually weaker part.

In order to facilitate the loading operation of the semi-trailer 2, within the scope of the present invention, we can set a pedal or a pedal or A protrusion 39, the upper surface of the pedal is used to press against the part behind the front lower surface 36 of the semi-trailer 2, and this is to fold down the stand and then return it again during loading and unloading and finally transport The bracket. This protrusion also serves to ensure positioning. These are clear in Figure 7.

In a second example, the second tractor 4 is in place after rolling up the entry ramp or base 15, while an example is shown in FIGS. 7-9, each rear wheel 33 and 34 will be in place on the between the transverse tubular members 23 and 24 of the transverse support structure 22 . Then it is swung to a high place, and during the movement, the transverse tubular members 23 and 24 rise up again along the rear wheels 33 and 34 wedged in the opening until the distance between the ends of the transverse members 23 and 24 is a predetermined wedge engagement. depth.

As mentioned, the lateral support structure 22 may be discontinuous. Instead it acts on each side constituting the two tube ends supported by the end of the arm and serves to accommodate the rear wheels 33 and 34 of the tractor 4 as described above.

Each of these tube ends has a free end or can be rejoined at its corresponding part, for example, by a closed tube, so as to form an opening of limited external dimensions, which we call a basket ring (panier) (the scheme is not shown). ).

The principle of fixing the rear wheels of the tractor is the same. At the start of lifting, the transverse support structure holds the rear wheels 33 and 34 of the tractor 4 and creates sufficient fixation for transport.

Continuing the upward swing movement drives the rear tractor 4 upwards until the raised position for transport.

Care must be taken that when the rear tractor 4 is swinging upwards, it is in a sufficiently inclined downward position towards the driver's cab so that it does not interfere with the corresponding end of the railway installation 1 when the load-bearing structure 10 of the railway is returned to a straight line. The upper structure of the subassembly 5 or 6, the latter presents a higher structural form than the bottom of the pivotable railway load-carrying structure 10, on which the front wheels of the tractor 4 are placed.

The reason why the front of the semi-trailer 2 obviously does not interfere with the superstructure of the end assembly 5 or 6 is the reduced height relative to the ground to the chassis at the front of the trailer pivot or kingpin 30 and the transverse support structure 22 is reduced in thickness.

The importance of the pivotable support 17 during loading and unloading is to be pointed out here in particular.

The lateral support structure 22 of the swingable support 17 rests on the floor of the platform or on an access ramp or base 15 of the platform which is typically used during interface operations at the platform during loading and unloading.

In the operation of bringing in the semi-trailer 2, either to make it run backwards or to move forward, the rear wheels 33 and 34 of the tractor 4 pass over the first tubular member 23, causing a perceptible The suspension is jumpy and easily felt by the driver. This results in a positioning signal. The driver knows that the semi-trailer 2 has reached a fixed and ready-to-transport location.

In a similar manner, the spanning of the first transverse tubular member 23 is used as a positioning signal when the second tractor 4 is driven forward to load it in the load-bearing structure 10 of the railway.

The semi-trailer 2 can then be disassembled and disengaged within the load-bearing structure 10 of the railway on its supports 37 and 38, or on the raised portion 39 of the carriage floor. In the instance in which the second tractor 4 is transported, the tractor is engaged in the other direction and is secured in this position and thus can remain because it is in the loaded position.

It is perfectly understandable that the lateral support structure 22 has the added advantage that it can also serve as a reference point relative to the ground for the loading position.

We note that an additional advantage of semi-trailer loading and unloading is that the support and lift swingable assembly 17 can both support and lift the semi-trailer 2 slightly, and the arms 18 and 19 of the swingable support 17 are lifted. After locking, it is fixed and held in the loaded position of the railway load-bearing structure 10 , that is to say before the assembly of the railway load-bearing structure 10 with the end components 5 and 6 of the railway installation 1 takes place.

It is thus possible to check the load distribution and subsequent unloading before the load-bearing structure 10 of the railway is assembled with the end assemblies 5 and 6 of the railway installation 1 , retracting or folding the brackets 37 and 38 back. As a supplement, it can also be checked whether the semi-trailer is parked in a suitable position.

In the case of the raised portion 39 of the car floor of the load-bearing structure 10 of the railway, the use of brackets can be avoided.

Of course, a stand can also be used in order to support the semi-trailer in its transport position.

The combined rail/road rail unit 1 can be used to transport the two tractors 3 and 4 of the semi-trailer or motor vehicles of equal or very close length.

The first motor vehicle is for example the first tractor 3 which, in the transport position, is fixed horizontally on the floor and behind the load-bearing structure 10 of the railway, which is placed obliquely for loading.

Then the second tractor 4, the rear axle 35 needs to be arranged perpendicular to the fixed area eg on an access ramp or on the extension of the access surface of the base 15 or any equivalent on the platform.

To this end, when the pivotable support 17 is in the low position, but it remains partially raised, the transverse members 23 and 24 of the transverse support structure 22 of the pivotable support 17 can be slightly embedded in the access ramp or base 15 or within the analogue.

After the second tractor 4 is in place, in order to secure the wheels 33 and 34 of the rear axle 35 between the transverse members 23 and 24 of the transverse support structure 22, the pivotable support 17 is lifted up to its transport position. , that is to say, it is possible to assemble the pivotable load-bearing structure with one or more end assemblies 5 or 6 of the railway installation 1 without any technical obstacles and interferences.

This transport inclined position allows to place the semi-trailer 2 in place and transport the two tractors 3 and 4 constituting an assembly in the same rail installation as a road without using other technical adaptations and with great operational convenience.

According to a variant, in the case of loading a semi-trailer 2, the lower surface 36 of the front axle part of the chassis is received by the central surface of the support, denoted support and maintenance plate 25 of the transverse support structure 22 of the swingable support 17 Brackets 37 and 38 and guards for unloading or stowing the semi-trailer 2 and, if necessary, kingpin 30 for holding the trailer turntable.

As a supplement, we will make a clear explanation below.

Once the semi-trailer 2 or the second tractor is loaded, the arms 18 and 19 of the swingable support 17 are raised and locked in the transport position and when the load-bearing structure 10 of the railway is still in the loaded inclined position components of the device.

The operation of the pivotable support 17 is preferably ensured by a motorized device as the substructure, that is to say the platform installation.

We can easily adapt to the different heights of the front lower surface 36 of existing different types of semi-trailers 2 .

During transport, when the lateral support structure 22 is no longer acting as a secondary support, the main vertical sustaining force is provided by brackets 37 and 38 .

The use of only one rail arrangement 1 ensures the transportation of both types of road loads.

There is no need to make the size of the carriage longer to transport the tractor, and the increased size would limit the use of the system from a compatibility point of view.

To increase the safety of the road load, it is locked in the tilted position of the support structure when it is loaded.

The invention also relates to a method of loading and unloading one or more road loads of the type described in the opening part of this description.

The railway installation 1 can be disassembled by releasing the assembly device and pivoting the railway load-bearing structure 10 so that one end 11 or 12 touches the ground of the platform or is placed or fixed on the railway load-bearing structure 10. An access ramp or base 15 on the platform.

The lateral support structure 22 of the pivotable support 17 is introduced into the ground of the platform or in contact with the access ramp or structure of the base 15 .

The trailer half 2 is towed or pushed onto the load-bearing structure 10 of the railway by a tractor 3 or 4 traveling forward or backward towards the load-bearing structure 10 of the railway, which enters through one end 11 or 12 and passes through it. The lateral support structure 22 on the access ramp or base 15 .

The rear axle 35 of the tractor 3 or 4 straddles the transverse support structure 22 with its rear wheels 33 and 34 at this point when the semi-trailer is fully pulled in. The driver continues to move and when he feels a shock that characterizes his rear wheel jumping the first cross member 23 of the transverse support structure 22 , that is, just after crossing, that is to say after the rear wheel is just on the two sides of the transverse support structure 22 Between the cross members 23 and 24, he immediately stops the tractor.

With respect to positioning, then it is that the semi-trailer is in a suitable position for external handling of the loading and transport of the semi-trailer.

Lower the brackets 37 and 38 of the semi-trailer 2, or use the protruding part 39 of the floor of the car, and only lower the suspension part of the tractor. Its wheels and the overhang 39 of the floor of the carriage.

Thus, the swingable support 17 is activated to swing upward. After its use, such as positioning, the transverse support structure 22 rests on the front lower surface of the semi-trailer and is in such a position that the receiving and holding cavity 28 is in the position surrounding the kingpin 30 of the trailer turntable.

This transverse support structure 22 remains pressed against the relative lower surface of the semi-trailer, with more or less force depending on the action of the pivotable arms 18 and 19 of the pivotable support 17 . A simple fixed support can be considered because it corresponds to a loading situation in which the support supports all or most of the vertical forces. In some instances, it may be preferred to have a standing stand along which the front axle of the semi-trailer is partly or completely supported by the swingable support 17, which unloads the stands 37 and 38 and due to the increased holding force Improved loading stability.

The transverse support structure 22 is secured in this position by latches and the supports 37 and 38 are in the holding position or the retracted or folded position as the case may be.

After possible fastening by other means, the loading operation is complete. The load-bearing structure 10 of the railway is pivotable to return to its rectilinear position for transport. After assembling the load-bearing structure of the railway with one or more end assemblies 5 or 6, the railway transport device is ready to go.

Uninstallation works in the reverse direction.

Loading of tractors 3 and 4 takes place in a slightly different manner.

After being disassembled obliquely and to be placed on the ground of the platform at the entry end 11 or 12 of the load-bearing structure 10 of the railway or fixed on an entry ramp or base 15 on the platform, the first tractor 3 is placed on the railway's The bottom of the load-carrying structure 10 runs all the way into the endmost position. After the first tractor 3 is fixed and loaded, the second tractor 4 moves forward and enters the bearing structure 10 of the railway.

When the driver feels a shock across the first transverse member 23 of the transverse support structure 22, the transverse support structure 22, as described above, is on the ground or setting of the platform or on an access ramp or base 15, where the rear wheels just sit After the position between the two transverse members 23 and 24 of the transverse support structure 22, he secures the tractor. The driver leaves the tractor after full braking.

We raise the pivotable support 17 . During this action the rear wheels 33 and 34 are secured by the raised cross members 23 and 24 which are then raised to a position high enough so as not to interfere with the superstructure of the end assembly 5 or 6 . We lock the pivotable bearing 17 in this position.

The second tractor is in a fixed state in which its rear wheels 33 and 34 are fixed by the cross members 23 and 24 of the cross support structure 22 .

Due to the weight possessed by the tractor 4, this fixation has proven to be important. It is also possible that additional fastening or another locking device is required for safety reasons.

We close the railroad again, pivot the load-bearing structure 10 of the railroad, and combine the one or more separate ends 11 or 12 into an end assembly 5 or 6 . The rail transport device is thus ready to go.

Uninstallation works in the reverse direction and requires no special description.
