Description

The present invention relates to a device for lifting and driving a turn of a railway freight car structure for combined rail-road transportation of goods.

The use of wagons for the combined rail-road transportation of goods with a cargo railway structure requires the presence of external drive mechanisms to provide a drive for turning a rotary cargo railway structure.

As a rule, we are talking about simple tools installed on the car and using the energy used in the train.

In this regard, mention should be made of PCT patent application No. 8102142 in the name of BERENS.

These known solutions also provide for the presence of gearboxes and couplers for converting the rotational motion received from the mechanical source into rotary motion.

These solutions have many significant disadvantages. The first of them consists in the need to consume the energy used in the train, which cannot be sufficient and therefore makes maneuvers slow due to the insignificant drive forces acting on the equipment. In addition, such energy consumption adversely affects the efficiency of other train equipment, in particular mechanisms and devices that ensure ride safety.

The second drawback is related to the cost of such mechanisms. This system requires the presence of at least one mechanism for each car, which cannot be used for other cars.

The third drawback concerns the amplitude of the turning maneuver. Indeed, none of the known devices allows you to disconnect all the ends of the cargo railway structure and thereby achieve the maximum amplitude of the turning movements. The convenience of maneuvers, as well as their effectiveness, safety and speed, depends on the magnitude of this turning amplitude.

The last drawback is the need for special maintenance of these mechanisms, which increases the total cost of maintenance of wagons.

The objective of the present invention is to provide a combined device for lifting and driving a turn of a freight railway structure as part of the combined rail-road transportation of goods, eliminating all these disadvantages while maintaining sufficient flexibility in use.

This device is characterized by the presence of at least one means of driving a rolling motion on the ground, which enters the support-lifting contact and then into the rolling contact to drive rotation, at least one zone on the lower side of at least one end of the cargo railway structure for the pivotal movement of at least this end to carry out operations of loading goods into a cargo railway structure or unloading cargo outside it.

Other features and advantages of the present invention will be more apparent from the following description, given by way of example, and the accompanying drawings, in which:

Figure 1 is a schematic illustration of a loading and unloading post, illustrating a lifting device on a railway track and mechanized bearing rollers on the platform.

A lifting device, the description of which follows, which also carries out the lowering of a freight railway structure, would more accurately be called a lifting and lowering device. To simplify the description, in the future we will call it simply a lifting device for performing this function. It also provides a turning drive for a freight rail.

As shown in figure 1, the combined device for lifting and driving turn 1 is made with the possibility of installation on the railway track 2 with two loading platforms 3 and 4, equipped on both sides of the track 2. Preferably, the device 1 is installed between two rails of the loading and unloading post 5, in the General form shown in figure 1. Depending on the type of corral, in particular for the car used at the post shown in FIG. 1, it may be necessary to use two lifting devices, such as device 1, one for each end of the freight railway structure 6. Indeed, in the presented case, this the load structure is lifted simultaneously at both ends and rotated around a central rotary assembly not shown in the figure. It can also be about turning around the end of the rotary node.

For simplicity, only one device will be described below, since both devices 1 for lifting and turning drive are identical.

This device 1 is supplemented by a number of bearing and, preferably, drive rollers, for example, two sets of three rollers 7 and 8, respectively mounted on platforms 3 and 4 and designed to receive, move and, possibly, but not necessarily, continue the turn of the cargo railway structure 6 by acting on its bottom, as soon as its overhang over the platform crosses a certain boundary, thereby ensuring sufficient stability and security of cornering movements. The rollers of these kits 7 to 8 are installed in a recess in the platform structure, as shown in figure 1, at a sufficient distance from the edge of the platform. They protrude slightly above the surface of the platform to freely move the bottom of the cargo structure hanging over the platform. These rollers are preferably mechanized and made in the form of nodes, each of which is formed by a rotating cylinder 9, essentially having the shape of a truncated cone, to differentiate the difference in circular speeds from one end to the other in order to avoid slipping. Their side surface is preferably covered with a metal rim 10 that comes into contact with the reference raceway 11 (figure 4), made at least at one end of the freight railway structure 6 of the car. They contain an electric motor 12, a rotating roller around its axis.

As indicated, freight rail structures 6 comprise, on the lower side of at least one of their ends, a flat raceway 11, for example, in the form of a plate of a suitable size or in any other embodiment. Due to the rotational nature of the movement, the track 11 is made in the form of a circle of arc located between the cargo railway structure and the carriage and is centered on the rotary node of the cargo railway structure 6, as shown in FIG. 4.

Although the variant with two devices for raising and driving a turn was presented above, it should be borne in mind that the present invention also relates to embodiments with a single device, for example, with a swivel assembly at the end or in any other place offset from the center of the car.

In this case, the combined device for lifting and driving the rotation is essentially identical or similar to the device described below, and therefore, there is no need to provide a new description.

Basically, the device for lifting and turning drive in accordance with the present invention is made in the form of a mechanical complex 13, mounted on a railway track 2 between two rails at the level of a place equipped for loading and unloading, hereinafter referred to as the loading and unloading post 5. Lower parts of this mechanical complex 13 are placed in a recess made with the possibility of minimal protrusion of this complex above the ground. The portion located in the ground is preferably protected from weather and other external factors by means of a protective plate.

You can also install the mechanical complex 13 on a movable trolley moving along the path into the trench between the rails.

For the upper part, you can also provide removable weather protection, for example, in the form of a casing (not shown in the figure).

The mechanical complex 13 of the device in accordance with the present invention can also be mounted on a base plate, providing mechanical stability and mounting on a trench or on a mounting bracket between the rails. To simplify the drawing, these tools are not shown in the figure.

The mechanical complex 13 of the device 1 in accordance with the present invention contains, on the one hand, a rotary casing 14, rotating around a horizontal axis 15. The rotary casing 14 is divided into two or more branches 16 and 17, at the end of each of which there is a mechanized block 18 and 19 formed by mechanized rollers 20 and 21 interconnected by a common transverse tubular element 22. Each mechanized roller 20 or 21 is also mounted on a hinged swivel bracket 23 and 24. The transverse tubular element 22 passes through to the ends of the branches 16 and 17 in the sleeve, mounted with the possibility of snapping in the gripping part 25, containing the entrance in the form of a V-shaped profile. Each swivel hinge bracket 23 and 24 is connected to the leading rod of the lifting jack 26 and 27, respectively, the housing of which is mounted to rotate around the axis 28 and 29 with a deformable bearing on the auxiliary brackets 30 and 31, respectively, made, for example, in the form of two parallel eyes 32 and 33, providing them with the ability to absorb lateral deviations. These lifting jacks 26 and 27 act with an upward pushing force on the hinged brackets with the mechanized roller blocks mounted on them, forcing them to simultaneously carry out the lifting movement.

The mechanized rollers 20 and 21 are rollers of the same type as described previously, since they form kits located on the platform. Each of them contains a rotating cylinder 9, covered with a metal rim 10 essentially in the form of a truncated cone. They are mounted on a longitudinal axis radial relative to the rotary assembly of the cargo structure 6, around which rotation occurs under the action of the drive electric motor 12. They converge slightly in the direction of the rotary assembly of the cargo structure 6, which is central in this example. This arrangement avoids lateral displacement during lifting contact and movement of the rotation drive of this cargo structure 6.

These mechanized rollers 20 and 21 are designed to enter, at the first stage, into vertical pushing contact with a raceway made on the lower side of at least one end of the cargo railway structure (Fig. 4), for its lifting under the action of lifting jacks . After lifting the load structure, their forced rotation forces the cargo railway structure to rotate by forcing rolling along the reference raceway.

To ensure full tight contact between the mechanized rollers 20 and 21 and the supporting raceway 11, a compensation mechanism shown in Figs. 5-8 is provided, which ensures the movement of the rotary axis 15 of the rotary casing 14 and allows, to avoid premature wear, to adjust the rotational movements of the rotary casing 14 with rolling means to provide a finite, essentially rectilinear and vertical approach and lift path to prevent displacement between each mechanized roller and road burn at the time of contact and during lifting.

The example below shows how this happens. Other equivalent solutions are also possible within the scope of the present invention.

According to this embodiment, the rotary axis 15 of the rotary casing 14 can move relative to its original position corresponding to the retracted horizontal position of the casing in the idle state. Its movement allows you to give the end of the casing and, therefore, mechanized rollers almost vertical path provided by lifting jacks on the part of the path corresponding to the final stage of rapprochement and lifting.

The following tools are involved.

The rotary axis 15 of the rotary casing is installed, for example, by each of its ends in two earrings, which are also made to rotate around the auxiliary axis 34.

During idle of the lifting jacks, that is, until the mechanized rollers come into contact with the road rolling support, no tangible pushing force acts on the rollers. Lifting jacks simply lift mechanized casters. The casing 14 is rotated only around its pivot axis 15, which remains stationary relative to its original position (Fig.6 and 7).

Since this rotary axis 15 is movable, it moves forward under the action of oblique traction from the casing lifted by jacks. With this configuration, a slight movement of the rotary axis 15 of the casing 14 provides lengthening of the shoulder of the geometric lever to convert a circular path along an arc into an almost rectilinear section on the final part of the path (Fig. 8 and 9).

An embodiment of the device has been described above, according to which the lifting means and the rolling means are combined into one mechanical complex 13.

It should be clarified that all similar embodiments in which the lifting means and rolling means are not combined, that is, located one after another or separately from each other, are also part of the same inventive concept.

A combination of lifting and rolling movements may also be used. In all cases, relevant embodiments are within the scope of the present invention.

So, an additional function can be given to the rotatable casing. It may contain a means of maintaining and holding in the position of the corresponding terminal platform of the car during loading and unloading operations. This tool is shown in Fig. 9, where the upper side of the casing 14 contains a gripping and blocking structure 35 of a Y-shape in which the edge 36 of the downwardly directed bend 37 of the body of the end pads is locked.

The operation of the device includes the following basic operations.

The carriage for combined rail and road transportation is stopped motionless with some tolerance at the location of the loading and unloading post 5, for example, for loading cargo.

The stop position of the car in the intended place corresponds to the positions of the end platforms, which must be held in case of a stationary stop of the latter by means of an appropriate device for each site installed on the railway track. If we are talking about individual devices, then these devices are activated. In other cases provided for by the present invention, the relative positions are held automatically by mechanical connection between the end pads or by applying the additional function of the device (s) for lifting and turning, such as described above.

So, drive the device (a) for lifting and turning. The lifting jacks act to ensure that the mechanized rollers 20 and 21 come closer to the corresponding supporting raceway 11 of the lower side of the end of the cargo rail structure 6. The mechanized rollers 20 and 21 are raised until they reach soft and tight contact with the supporting raceway 11 due to the clearance of the compensation mechanism. Further, after releasing the detachable connecting nodes between the cargo structure and the end platforms, coordinated lifting movements of both ends of the cargo railway structure or only one corresponding end occur.

The lift movement consists of two phases. The first is part of the movement corresponding to the expansion of the end platform suspensions. The second refers to the actual lift, which stops shortly after the ends are disconnected between the load-carrying structure 6 and the gripping nodes of the end platforms, while the additional rise, as a rule, occurs to a small height, since at the end platforms nothing interferes with the turn.

After that, the mechanized rollers 20 and 21 are driven into rotation by their engines, forcing the ends of the rotary cargo structure of the car body to rotate in the same direction of rotation until the ends of the cargo structure 6 reach the corresponding angles by means of sets 7 and 8 of mechanized rolling support means on the platform.

The track (11) on the lower side of at least one end of the cargo structure is made in the form of an arc of a circle centered on the axis of rotation of the cargo structure and the car.

The rotation is carried out until the ends of the cargo railway structure are completely disconnected from each end platform, and a sufficient angular deviation is provided to ensure the convenience of loading and unloading maneuvers.

After this, loading or unloading may begin. At the same time, automobile cargo falls onto the freight railway structure autonomously, for example, on a semi-trailer moved by a tractor vehicle.

The closing movement of the car is carried out in the reverse order.
