Description

Bridge element

The present invention relates to a bridge element which can be carried on a transfer device, in particular on a transfer with a transfer tank and on a transfer vehicle, to form optionally a short or long bridge.

In the early 1970s, long bridges were first proposed, with a 22 m bridge width, capable of flattening, where two halves of the bridge could be carried over the transfer tank and fully automatic interconnected to form a long bridge. These long bridges can be moved freely by the transfer device of the tank, pushing over and moving over obstacles to overcome, for example river flows. Similarly, restoration is possible.

Since a bridge length of 22m is not necessary in all cases, a short 11m long bridge, which can be transferred by the same transfer device, was later constructed in accordance with the construction principle of the long bridge. The transfer device itself has been modified such that the transfer tank can carry and transfer one long bridge or two short bridges.

That is, a certain problem has arisen that whether one long bridge should be used or two short bridges should be used before loading into the previous tank. Thus, a quick response to the changed demand was not possible.

European patent application EP 0 374 019 A1 discloses a bridge element of this kind. This bridge element consists essentially of a fixing ramp, a lane plate which is the upper flange of the framework, and a lower flange. The rain plate has a collapsible ramp tip that can be adjusted in a fixed ramp by a hinge and locked by the lower flange. The movable rain plate is installed or inclined by a hydraulic cylinder disposed on the previous vehicle or the lower flange. The lower flange is also firmly implemented so that the skeleton thus formed is statically determined and functions. The lamp tip is a conveying element of the skeleton and therefore must likewise be firmly shaped.

The moving rain plate is loaded by local bending and general forces when under load, whether used as a short bridge or as part of a long bridge. When used as a short bridge, ie an inclined lane plate, the rigidity of the bridge skeleton is realized only by tight locking of the lane plate and the lower flange.

Another bridge element having a similar structure is disclosed in German patent application DE-G 94 12 270 U1 or European patent application EP 0 391 149 B2. Even in this bridge element, the lower flange must be firmly implemented in order that the skeleton formed by the fixed ramp element, the moving lane plate, and the lower flange is statically determined and thus carrying capacity.

Another bridge element transferable by a previous vehicle and optionally for forming a short or long bridge is disclosed in European patent application EP 0 916 769B. This bridge element comprises a single, foldable lamp with a foldable lamp tip and a lower flange formed by a flexible tensioning flange connected by a transverse support in the area of the foldable lamp to ensure the required stability and shape. Include. This lamp extends half the length of the bridge element. In the raised position of the lamp, the lamp tip is firmly connected to a coupling installed in the lower flange. The free end of the tension flange is provided with a tension coupling. In order to complete the long bridge, a coupling is also provided on the upper flange. Only pressure acts on it, so a simple clutch coupling is sufficient.

This asymmetry of the bridge element prevents manipulation. Thus, after rotating the bridge element 180 degrees about its axis, for example after receiving the short bridge from the opposite side, the long bridge can be transferred. However, no known transfer device for this is provided.

In order to move the bridge element and the bridge produced by it, a drive is required, on the one hand, consisting of a set of pulleys and on the other hand a path. In many bridge devices, the path is part of the bridge element and the pulley set is part of the previous device installed in the previous vehicle. The path suffers from high wear. Because of this, these bridge elements must be repaired frequently. Alternatively, the route can be made of steel, in which case the weight is increased. Both methods are not satisfactory.

Another common disadvantage of the proposed bridge element is that only one short bridge or only one dual module long bridge can be produced from the bridge element. Therefore, use is clearly limited.

European patent application EP 0 757 132 B1 discloses a tank bridge comprising a foldable cross support. Stabilization is performed by spring elements. The pulley is installed on the bridge, and the path is installed on the previous device.

European patent application EP 0 685 599 B1 discloses a transfer device with a moveable balcony. Here, too, the pulley is installed in the bridge and the path is installed in the previous device.

European patent application EP 0 757 131 B1 discloses a coupling device for the connection of a bridge module. The pulley is installed on the bridge and the path is installed on the old device.

It is an object of the present invention to provide a bridge element which is variably usable and can be connected to any number of bridges if necessary.

The subject is formed by a ramp base having a bottom flange and a lane, the base element being shaped as a rigid support, and a ramp base which is movably adjustable lamp tip. At least one lamp adjusted at the element, the lamp being adjusted at both ends of the base element, the lamp base being shaped, raised or lowered, as a rigid U-shaped side or as a closed box-like support Can be firmly connected to the base element by a coupling in which the lamp tip is adjusted at the lamp base and in the extended end position forms the lamp together with the lamp base and at an angled end position. In the lower flange, the length of the lamp tip and the position of the coupling, A base is adjusted to form a flat lane with the base element in the raised position, a free end of the lower flange is provided with a tension coupling, a free end of the lamp base is provided with a pressure coupling, and the base There is a carrying element with a carrying pulley in the element, and there is a controlling element with a control pulley in the lamp base, wherein the carrying element and the control element are provided with a transfer device carried on the vehicle and the transfer device. It is solved by a bridge element characterized in that it cooperates with the provided installation rail.

Preferably, in the bridge device with a foldable ramp according to the invention, the vertical movement of the lamp at each end is effected by the transfer device.

The pulley set is fixed to the bridge element and the pulley path is present in the transfer device. This has the advantage that all parts which can be worn during the previous operation can be easily replaced. The guide rail of the transfer device carried on the transfer vehicle may be implemented with steel that is stable against wear. Wearing of the bridge element is not particularly required due to wear. The weight of the bridge element is not increased.

Guide pulleys installed on the lamp base are automatically adapted to push the bridge element horizontally or to descend into the path by partial inclination of the previous device when forming a short or long bridge without the need for special controls. It is arranged at the correct position of the upper or lower portion of the guide rail of the transfer device or the special installation rail installed there. Control pulleys installed on the lamp base are each used in support of a sudden situation in combination with a transport pulley disposed on the base element.

In addition, two horizontal stabilizers are arranged on the base element, which prevents the cited base element from tilting or pushing during installation of a long bridge.

According to an embodiment of the present invention, a double pulley may be installed below the transport pulley. Here, these pulley pairs have no function when in balance. The double pulley forms a stable three point pedestal that prevents the cited bridge from swinging back and forth. When constructing the entire bridge, the pulley pairs temporarily support the weight moment of the protruding bridge component. In the intermediate position the pulley pair performs an additional stabilization function.

By placing the pulley on the bridge element, the lower flange is not loaded by the bearing force of the pulley during the transfer. Thus, a form suitable for space and weight can be selected.

Preferably, the hinge between the base element and the lamp base is a continuous hinge band arranged to cover.

According to one embodiment of the invention, the base element and the lamp base are shaped as pressure flanges in the region of the lane. Here, a clutch coupling is provided at the end of this pressure flange.

According to one embodiment of the invention, the lower flange is shaped as a tensioning flange, wherein a tension coupling is provided at the end of the tensioning flange.

To relieve the hinge, the lamp tip is supported by a pressure surface against the lamp base in the raised or lowered position. Thus, the lamp tip can also accommodate gravity or bearing force.

Another task of the lamp tip is to protect the pressure bar of the lower flange-coupling and the upper flange in abutting areas against contamination and damage.

Preferably, in order to stabilize the protruding lower flange against lateral forces, the lamp tip and the lower flange are formally connected.

According to another embodiment of the present invention, a mechanism for connecting the rotational movement of the moving lamp base to the rotational movement of the moving lamp tip is firmly installed in the bridge element. This feature facilitates the transfer operation, which is of particular value when a battle occurs in the bridge, causing another reduction in the bridge weight.

Preferably, all members of the high load bridge element, such as the pressure side, are made of steel and all other members are made of light metal alloys, preferably very hard light metal alloys.

According to the present invention, there is provided a bridge element that is variably usable and can be connected to any number of bridges as needed.

1 shows a short bridge formed by individual bridge elements 10. This bridge element 10 comprises a fixed base element 1. Lamps are adjusted at both ends of the fixed base element 1, which are formed by a lamp base 2 and a lamp tip 3 adjusted therein. As a hinge between the base element 1 and the lamp base 2, a hinge configured to be covered is suitable. The length of the lamps 2, 3 is one quarter of the length of the bridge element. A tension flange 1 ′ proceeds below the ramps 2, 3 and the base member 1.

In the position shown in FIG. 1, the lamp base 2 and the lamp tip 3 are firmly connected to the base element 1. Details will be described with reference to FIG. 4. Thus, the bridge element 10 is fully usable as a short bridge.

2 shows that the bridge element 10 of FIG. 1 is modified to be inserted into a multi-module bridge as an intermediate element. For this purpose, the lamp base 2 forms a flat lane 9 by the hard base element 1 and is firmly connected to the base element 1. The lamp tip 3 is inclined downward and stands on the lower flange 1 ′ by means of a fitting coupling 15. Thus, the lower flange 1 'is stabilized against lateral forces. Details will be described with reference to FIG. 5.

3 shows a long bridge of a dual module consisting of two bridge elements 1. The end lamps 2, 3 are inclined downward as in FIG. The lamp base 2 located in the center of the long bridge is rotated upwards as shown in FIG. 2 and is supported in this position by the lamp tip 3 inclined downward. Thus, continuously flat lanes 9 are formed.

In order to transfer forces between the connected bridge elements 10, the base element 1 and the lamp base 2 are formed as pressure flanges in the region of the lane 9. In addition, the base element 1 and the lamp base 2 have a pressure coupling 4 'at the connecting position. In the simplest case, this is a shaped pressure bar that transmits not only pressure but also lateral forces. The lower flange 1 ′ is formed as a tension flange and has a tension coupling 4 at the point of connection. In the simplest case this is a clutch coupling. Overall, this carrying framework is formed so that the long bridge can withstand a large load, for example a combat tank of class MLC 70/80, at a bridge length of 26 m and a suitable dimension.

As shown in FIGS. 1-3, the bridge element 10 has three transport pulleys 5 on the base element 1.

In order to prevent the short or long bridges moving on the previous device from swinging around uncontrolled, at the bottom of the transport pulley 5, two horizontally stabilized devices 5 'are arranged at opposing horizontally spaced intervals. Can be arranged. The vertical spacing between the pulley 5 and the horizontal stabilizer 5 'is adjusted in accordance with the transfer device (Fig. 8) carried on the transfer vehicle. The horizontal stabilizer 5 'may also be formed with a pulley.

As can be seen in FIGS. 1-3, one control pulley 6 is present on one and / or another side of the lamp base 2. This control pulley 6 is located below the guide rail of the transfer device (FIG. 8) in the lowered lamp base 2 (FIG. 1), but in the raised ramp base 2 (FIG. 2) the transport pulley. (5) is present at the height. This is due to the interaction with the mounting rails A, A '(FIGS. 6-7 and 8) provided in the transfer apparatus by horizontal or vertical movement of the bridge element 10 during the transfer operation. Affected by Thus, the operation of the bridge element 10 is also used to adjust the length of the desired bridge during the previous operation without requiring additional adjustment mechanisms. Thus, short bridges can also be installed and transferred to long bridges with the transfer device.

4 is an enlarged partial cutaway view of FIG. 1. It is possible to see the end of the base element 1 in which the lamp base 2 is adjusted by a hinge 11, preferably a hinge band. The lamp base 2 is formed as a box-shaped side with a U-shaped cross section. The lamp base 2 comprises two, provided coupling openings 12, 13, so that it can be firmly connected to the base element 1 by a coupling bolt (not shown).

At the free end of the lamp base 2 the lamp tip 3 is adjusted by a hinge 14 to be supported against the lamp base 2 in the position shown. Here, a suitable support surface of steel is provided. In this position, the lamp base 2 and the lamp tip 3 transmit the load to the lower position, for example the ground of the river.

5 is an enlarged partial cutaway view of FIG. 2. The lamp base 2 is rotated high and together with the base element 1 forms the continuous flat lane 9. The lamp base 2 is firmly connected to the base element 1 by means of a coupling bolt (not shown) extending with the bolt opening 12.

The lamp tip 3 is rotated downward to stand in a formable coupling 15 on the bottom flange 1 ′. Due to the conformal coupling 15, the lamp tip 3 stabilizes the lower flange 1 ′ against lateral forces.

6 is an enlarged partial cutaway view of FIG. 2. The lamp base 2 is erected by the vertical movement C of the base element 1. The control pulley 6 is arranged on the mounting rail A provided in the previous device (FIG. 8) during the vertical movement of the base element 1, thus raising the lamp base 2.

FIG. 7 is another enlarged partial cutaway view of FIG. 2. In this embodiment, the lamp base 2 is erected by the horizontal movement B of the base element 1. During the horizontal movement B, the control pulley 6 is raised above the lamp of the mounting rail A 'of the previous device (Fig. 8), thus raising the lamp base 2.

8 only schematically shows a previous vehicle 20 in the form of a previous tank. The transfer device 21 already travels to the previous position. The base element 10 is completely preceded by the transfer device 21. Since the control pulley 6 is located under the installation rail 22, the lamp base 2 and the lamp tip 3 are in the extended position, and thus, FIGS. 1, 3, and 4. As shown in FIG.
