Description

The invention relates to a bridge laying vehicle with a verlegbaren bridge having two pivotally interconnected bridge elements, which are arranged folded in a transport position on the bridge laying vehicle, wherein one of the two bridge elements from the transport position by means of a bridge laying vehicle arranged pivoting device relative to the other bridge element is pivotable. Another subject of the invention is a method for laying a deployable bridge having two pivotally interconnected bridge elements, which are arranged folded in a transport position on a bridge laying vehicle, wherein one of the two bridge elements pivoted from the transport position by means arranged on the bridge laying vehicle pivoting device relative to the other bridge element becomes.

Layable bridges are used, in particular in military applications, as temporary bridges for crossing rivers and trenches in the field. Usually, the bridges are transported in a transport position of bridge laying vehicles and laid on site. For transport on the bridge laying vehicle, the bridges are often subdivided in the longitudinal direction into a plurality of bridge elements, which are lined up before laying.

The from the DE 10 2004 049 969 B3 known scissor bridge for laying with a bridge laying vehicle has two pivotally interconnected bridge elements, which are arranged folded in a transport position on the bridge laying vehicle. Before juxtaposing both bridge elements are pivoted together from the transport position relative to the bridge laying vehicle in a substantially vertical intermediate position. In the intermediate position, both bridge elements are located on the laying side of the bridge laying vehicle. For juxtaposing one of the two bridge elements is pivoted from the intermediate position relative to the other bridge element. The juxtaposed bridge elements are locked together and can then be routed across a river or ditch.

In this case, for the juxtaposition of the bridge elements before the pivoting of the one bridge element relative to the other, both bridge elements are first jointly pivoted relative to the bridge laying vehicle. For juxtaposing the bridge elements therefore two steps with two pivoting movements are required, resulting in a long installation time.

A simplified procedure results from the US 3 486 180 A known relocatable bridge, which has three pivotally interconnected bridge elements, which lie folded in a transport position folded on a bridge laying vehicle. For pivoting the outer bridge elements relative to the central bridge element from the transport position hydraulic cylinders are arranged on the bridge.
The NL 250 601 A discloses a bridge laying vehicle for laying a bridge with the features of the preamble of claim 1 with two pivotally interconnected bridge elements. In the transport position, the bridge elements are folded up on the bridge laying vehicle. In addition, a pivoting device in the manner of a mast is provided at the rear of the bridge laying vehicle, via which one of the two bridge elements is pivoted from the transport position relative to the other bridge element. When juxtaposing the bridge elements, however, results in a weight shift in the rear region of the bridge laying vehicle, which is why it is necessary to support the vehicle already during the juxtaposition of the bridge elements.
The object of the invention is to allow a favorable position of the center of gravity of the bridge laying vehicle when juxtaposing the bridge elements.
This object is achieved with a bridge laying vehicle mentioned at the beginning by the features of patent claim 1.
The bridge elements are mutually pivotable for juxtaposing from the transport position. Only one pivotal movement is required to line up the bridge elements to a bridge. The relocatable Bridge can be laid immediately after the pivoting of one of the two bridge elements from the transport position relative to the other bridge element.

Characterized in that a pivoting device is arranged for pivoting a bridge element on the bridge laying vehicle, the relocatable bridge can be constructed as such purely passive. In particular, no active components for pivoting need to be provided on the movable bridge.

The bridge elements of the deployable bridge may have a top flange. The upper belt may be formed as a carrier which carries the running surface. The running surface can be designed as a continuous surface or formed from track carriers. On the underside of the bridge element, which is opposite to the running surface, may also be provided a lower flange. The lower chord may also be designed as a carrier and connected to the upper chord by means of connecting elements, e.g. be connected via struts or a flat side wall.

Preferably, the upper chords of the bridge elements are in the transport position on each other. In the transport position, the running surfaces of the bridge face each other. After pivoting one of the bridge elements relative to the other bridge element, the bridge elements are oriented such that the upper straps of both bridge elements are directed upward.

More preferably, the bridge element from the transport position in an unfolded laying position is pivotable in which the two bridge elements are lined up in alignment. Because the bridge element can be pivoted from the transport position into an unfolded laying position, the bridge can be laid quickly. It is not necessary to first pivot both bridge elements relative to the bridge laying vehicle and then to pivot one of the two bridge elements from this intermediate position into an unfolded laying position. Rather, the bridge elements can be spent by unfolding a bridge element from the transport position in a laying position in which they are strung together.

According to the invention, the pivoting device is arranged on one side of the bridge laying vehicle, which is opposite to the laying side of the bridge laying vehicle on which the bridge can be laid in the laying position. This allows a favorable position of the center of gravity of bridge laying vehicle and bridge both in the transport position and when juxtaposing the bridge elements are made possible. In a bridge laying vehicle in which the bridge can be laid forward, the pivoting device can be arranged in the rear region of the bridge laying vehicle. Furthermore, the pivoting device can protrude beyond a side of the bridge laying vehicle.

It is advantageous if the swiveling device has a swivel arm. With a pivot arm, one of the two bridge elements can be pivoted relative to the other bridge element, in particular while the second bridge element rests on the bridge laying vehicle.

Preferably, the pivoting device has a drive for pivoting the bridge element. The drive can e.g. be electric, hydraulic or pneumatic.

More preferably, the pivoting device has a lock, in particular a bolt lock, for locking the pivoting device with the bridge element. By locking the pivoting device and the bridge element can be coupled together such that the pivoting device can act on the bridge element for pivoting the bridge element.

In a structural embodiment, the bridge laying vehicle has a holding device for holding a bridge element, in particular during pivoting of the other bridge element. By a holding device, a bridge element during pivoting of the other bridge element can be held fixed to the vehicle.

Preferably, the holding device is arranged on the laying side of the bridge laying vehicle. As a result, the bridge can be stored on the laying side during installation. The holding device can be formed by a laying arm of the bridge laying vehicle. Thus, the bridge can be kept in the transport position with the laying arm and laid in the laying position with the laying arm.

More preferably, the holding device has a bridge feed drive for laying the bridge. With a bridge feed drive, the bridge can be laid after juxtaposing. The bridge feed drive can also translate the bridge from the laying position cause. Thus, the juxtaposed bridge elements can be laid without further pivotal movement of the bridge elements is required.

It has proven to be advantageous if the bridge elements are connected to each other via a hinge on a top flange. A hinge on the upper flange, the bridge elements can be connected pivotally coupled to each other. The hinge can be arranged in particular in the upper flange of the bridge elements.

Preferably, the bridge elements have substantially the same length. In particular, the bridge elements can be made identical. This allows a modular design of the relocatable bridge are made possible. Furthermore, an embodiment of the bridge with bridge elements of the same length is advantageous for the transport.

In a further embodiment, the bridge elements in the juxtaposed position can be locked to one another via locking elements arranged on the bridge elements, which are arranged in each case in particular on a lower flange of the bridge elements. In order to ensure the cohesion of the deployable bridge, the juxtaposed bridge elements can be locked together before laying. By each arranged on a lower flange of the bridge elements locking elements, a tensile connection of the bridge elements can be made possible. The locking elements can absorb the tensile forces generated during the loading of the bridge, in particular by driving over the bridge with a vehicle.

Preferably, the locking elements are designed such that they lock automatically when juxtaposing the bridge elements together. The fact that the bridge elements automatically lock together when juxtaposed eliminates the time-consuming manual or drive-assisted locking of the bridge elements. The relocatable bridge can be laid immediately after stringing together.

In the following, possible embodiments of the locking elements arranged on the bridge elements will be explained. These can allow an automatically locking latching of the bridge elements.

Preferably, the locking elements are configured such that they automatically lock together when juxtaposed. The locking elements can run in pairs against each other and engage in a locking position. Furthermore, the locking elements can interlock during automatic locking such that they lock.

It is advantageous if a locking element, in particular by means of a spring, is biased, wherein the bias acts on the locking element in the direction of the locking position with a force. By the bias, the automatic locking of the locking element can be made possible. In particular, the locking element may be biased such that it is in the locking position as long as no further force acts on the locking element. In addition, the biasing force may act in a direction which is oblique or transverse to an inlet direction in which another locking element enters when juxtaposed in the prestressed locking element.

In the case of two locking elements in which a different locking element runs into the prestressed locking element, it is advantageous if the locking elements are designed such that, when the bridge elements are lined up, the other locking element exerts a force against the prestressing force. As a result, the prestressed locking element can be moved out of the locking position when the bridge elements are arranged side by side in a non-locking position. Furthermore, it is possible that the locking elements are continuously approached to each other to open the biased locking element against the bias. The other locking element may cause a force with a force component acting against the biasing force when juxtaposing the bridge elements.

Preferably, a locking element has a sloping guide, via which a locking element is opened when juxtaposing the bridge elements. By a sloping guide a juxtaposing the bridge elements a force component is made possible obliquely to the inlet direction of the locking elements. By a force component obliquely to the direction of movement of the bridge elements, in particular a biased locking element can be opened.

In a structural embodiment, a locking element is pivotally mounted. A pivotally mounted locking element can be pivoted in the locked position and swung open when juxtaposing the bridge elements. Moreover, the locking element can be swung open to open the lock.

More preferably, a locking element on a Verriegelungsktinke. A locking pawl can lock in the locking position in a engage other bridge element and / or another locking element.

Furthermore, it is advantageous if a locking element has a locking pliers for embracing the other locking element. The locking pliers may have jaws, between which another locking element is receivable in the locking position.

More preferably, a locking element on a locking bolt. The locking bolt may be configured such that it is suitable for receiving in the other locking element. In particular, the locking bolt may have a longitudinal axis, which is aligned substantially transversely to the inlet direction of the locking elements when juxtaposing the bridge elements. As a result, the embracing of the locking bolt by the other locking element can be made possible. In particular, a locking pliers can embrace the locking bolt.

• In einer bevorzugten Ausgestaltung weist die Brücke ein Öffnungselement zum Entriegeln der Verriegelungselemente auf. Das Öffnungselement kann entgegen der Vorspannungskraft eines vorgespannten Verriegelungselements wirken. Durch das Öffnungselement können die Verriegelungselemente, insbesondere entgegen der Vorspannungskraft, entriegelt werden.

In the following, advantageous embodiments of the relocatable bridge relating to the opening of the lock will be described:

• In a preferred embodiment, the bridge has an opening element for unlocking the locking elements. The opening element may act against the biasing force of a biased locking element. Through the opening element, the locking elements, in particular against the biasing force can be unlocked.

In a further embodiment of the invention, the opening element comprises a guide which, when moving the opening element, a locking element opens. Through the rotary element, the movement of the opening element can be transmitted to the locking element. Thus, the opening element is adapted to act to unlock the lock on the locking element. The locking element can be acted upon by a force acting counter to the biasing force.

Preferably, the opening element can be actuated by means of a drive. The drive can e.g. be electric, pneumatic or hydraulic. The opening element may alternatively be manually operated.

In a locking element having a locking pliers, the opening element may be configured such that it can act on the legs of the locking pliers to open the locking pliers. The locking pliers can be spread by the opening element. In particular, the legs of the locking pliers can be swung open by means of the opening element in order to release the other locking element accommodated for locking in the locking pliers.

In a method mentioned above, the above object is achieved by the features of claim 13.

The bridge elements are pivoted for juxtaposing from the transport position against each other. Only one pivotal movement is required to line up the bridge elements to a bridge. The relocatable bridge can be moved immediately after the pivoting of one of the two bridge elements from the transport position relative to the other bridge element.

In a further embodiment of the method, the bridge elements, in particular on a lower flange, are coupled together, while one of the bridge elements rests on the bridge laying vehicle. The bridge elements can be locked in coupling such that they are firmly connected to a bridge.

Preferably, the bridge element is pivoted from the transport position into an unfolded laying position, in which the two bridge elements are lined up in alignment.

More preferably, the bridge is moved in the laying position for laying in the direction of the laying side of the bridge laying vehicle, in particular moved. The bridge can be laid out of the laying position while maintaining a low silhouette over the obstacle. From the laying, in which the bridge elements are lined up, no further pivoting movement of the bridge elements is required for laying.

It is advantageous if the locking elements automatically lock together when juxtaposing the bridge elements. By automatically locking the bridge elements a quick juxtaposition of the bridge elements is possible. The bridge is after the juxtaposition as soon as possible ready for use and can be relocated.

In a further embodiment of the method, the bridge elements are pivotally connected to each other and are pivoted to each other for juxtaposing. By pivoting the coupling regions of the bridge elements to be locked can be approximated to each other.

Preferably, the locking elements run when juxtaposing the bridge elements against each other, wherein a locking element automatically opens when entering the other locking element and then locked automatically. The locking element can be moved from the locking position into a non-locking position when entering the other locking element to then automatically engage in the other locking element. In particular, the locking element may be biased such that the other locking element acts in juxtaposition of the bridge elements against the bias of the locking element and this opens automatically.

Moreover, the advantageous embodiments described in relation to the bridge laying vehicle according to the invention can also be used in the method according to the invention.

An advantageous embodiment of the invention will be described with reference to Fig. 1 to 8 described.

In the Fig. 1 a bridge laying vehicle 14 is shown, which is designed as a tracked vehicle. In the front area, the bridge laying vehicle 14 has a holding device 12 for holding and laying a deployable bridge 1, which is pivotably articulated to the chassis of the bridge laying vehicle 14. On the holding device 12, two roller carriage 27, 28 and a bridge feed drive 24 are arranged. In addition, the bridge laying vehicle 14 below the holding device 12 has a support plate 20, which in the illustration in Fig. 1 in a raised driving position.

On the rear side of the bridge laying vehicle 14, which is opposite to the arranged as a laying arm holding device 12, a pivoting device 13 is further arranged. This is designed in the manner of a cantilever, which projects over the rear of the vehicle. The pivoting device 13 further comprises a pivoting arm 19, which is arranged pivotably about the pivot axis C. For locking the pivoting device 13 with a bridge element 2, the pivot arm 19 has a locking element 22. On the top of the pivot arm 19, a throwing device 23 is also arranged, which is suitable for dropping projectile. In addition, two unlocking drives 25, 26 are arranged on the pivoting device 13.

In the presentation in the Fig. 2 is on the bridge laying vehicle 14, a bridge 1, which comprises two identical bridge elements 2, 3. For transport with the bridge laying vehicle 14, the bridge 1 is folded such that the upper straps of the pivotally interconnected bridge elements 2, 3 rest on each other. In this transport position, the lower bridge element 3 is held by the holding device 12 arranged in the front region of the bridge laying vehicle 14. These are the front and Rear roller carriage 27, 28 of the holding device 12 is inserted into a guide in the lower flange 11 of the bridge element 3.

The upper bridge element 2 is held in the transport position by the pivoting device 13. The pivot arm 19 of the pivoting device 13 is pivoted forwardly so that the locking element 22 can engage in an opening on the bridge element. Furthermore, in order to achieve a fixed coupling of the bridge elements 2, 3 when stacked, locking elements 4, 5 arranged on the two lower bridge elements 2, 3 are provided on both bridge elements 2, 3.

• In der Fig. 3a ist ein Brückenverlegefahrzeug 14 mit einer verlegbaren Brücke 1 in der Transportstellung dargestellt. Auf der Verlegeseite des Brückenverlegefahrzeugs 14, auf der die Haltevorrichtung 12 angeordnet ist, befindet sich ein Hindernis 21, welches durch einen Flusslauf oder eine Vertiefung im Gelände gebildet werden kann.

Based on Fig. 3a to 3e will be explained below the method according to the invention for laying a relocatable bridge 1:

• In the Fig. 3a a bridge laying vehicle 14 is shown with a verlegbaren bridge 1 in the transport position. On the laying side of the bridge laying vehicle 14, on which the holding device 12 is arranged, there is an obstacle 21, which can be formed by a river course or a depression in the terrain.

Before the bridge 1 can be laid with the holding device 12 of the bridge laying vehicle 14, the bridge elements 2, 3 must be strung together. For this purpose, the upper bridge element 2 is pivoted from the transport position by means of the pivoting device 13 with respect to the bridge element 3 to the rear, cf. Fig. 3b , During this unfolding of the bridge elements 2, 3 about the pivot axis C of the pivot arm 19, the lower bridge element 3 rests on the bridge laying vehicle 14. The pivot axis C of the pivot arm 19 is equal to the pivot axis of the bridge elements 2, 3rd

By the pivoting device 13, the bridge 1 can be spent in one step from the transport position in the laying position in which the bridge elements 2, 3 are lined up in alignment, see. Fig. 3c , In order to achieve a fixed coupling of the bridge elements 2, 3, the bridge elements 2, 3 are locked together when juxtaposed by means of the locking elements 4, 5. By unfolding the bridge elements 2, 3 above the bridge laying vehicle 14 results in a favorable center of gravity distribution, which allows the bridge elements 2, 3 without additional support of the bridge laying vehicle 14 lined up by the support plate 20.

The support plate 20 is required only when laying the bridge 1 on the obstacle 21 from the laying position, see. 3d figure , For this purpose, the support plate 20 is extended on the laying side of the bridge laying vehicle 14, so that the bridge laying vehicle 14 is additionally supported on the laying side on the support plate 20. Before laying the bridge 1 in the direction of the laying side of the bridge laying vehicle 14, the locking element 22 of the pivoting device 13 is released from the bridge element 2. Further, the holding device 12 is pivoted with the jaw bridge 1 so that the bridge 1 is no longer in contact with the pivoting device 13. For laying the bridge 1 with the bridge feed drive 24 of the holding device 12, the bridge 1 is moved in the direction of the obstacle 21. The juxtaposed bridge 1 is guided during installation with the holding device 12 by the front and rear roller carriage 27, 28 and can be installed while maintaining a low silhouette over the obstacle 21.

In the illustration in Fig. 3e the bridge 1 is completely above the obstacle 21. The holding device 12 is pivoted such that the side facing away from the bridge laying vehicle 14 of the bridge 1 after laying is inclined down. As a result, first the side of the bridge 1 can be deposited, which faces away from the bridge laying vehicle 14. In a further step, the side of the bridge 1, which faces the bridge laying vehicle 14, can also be deposited. For this purpose, the holding device 12 is pivoted so far that the bridge laying vehicle 14 facing side of the bridge 1 reaches the ground in front of the obstacle 21.

In the described bridge laying vehicle 14, only one pivotal movement is required in order to line the bridge elements 2, 3 to form a bridge 1. The relocatable bridge 1 can be laid immediately after the pivoting of one of the two bridge elements 2 from the transport position relative to the other bridge element 3.

• Wie in der perspektivischen Detailansicht des Koppelbereichs der Brückenelemente 2 und 3 in der Fig. 4 dargestellt, sind die Brückenelemente 2, 3 am Obergurt 9 mit einem Scharnier 7 schwenkgekoppelt miteinander verbunden. Am Untergurt 11 der Brückenelemente 2, 3 sind die Verriegelungselemente 4, 5 paarweise derart angeordnet, dass diese beim Aufklappen der Brückenelemente 2, 3 gegeneinander laufen und in der Verriegelungsstellung ineinander greifen. Ferner sind die Verriegelungselemente 4, 5 komplementär an den Brückenelementen 2, 3 positioniert, so dass ein am Brückenelement 2 angeordnetes Verriegelungselement 4 in der Verriegelungsstellung jeweils mit einem an dem Brückenelement 3 angeordneten Verriegelungselement 5 verriegelt und umgekehrt.

Based on Fig. 4 In the following, the locking of the bridge elements 2, 3 when stacked together to form a bridge 1 will be described:

• As in the perspective detailed view of the coupling region of the bridge elements 2 and 3 in the Fig. 4 illustrated, the bridge elements 2, 3 are connected to the upper flange 9 with a hinge 7 pivotally connected to each other. At the lower flange 11 of the bridge elements 2, 3, the locking elements 4, 5 are arranged in pairs so that they run against each other during the unfolding of the bridge elements 2, 3 and engage in the locking position. Furthermore, the locking elements 4, 5 are positioned complementarily to the bridge elements 2, 3, so that a locking element 4 arranged on the bridge element 2 is locked in the locking position in each case with a locking element 5 arranged on the bridge element 3 and vice versa.

The laid bridge 1 must be able to absorb both compressive and tensile forces during the passage of vehicles in the coupling region of the bridge elements 2, 3. In the region of the hinge 7, compressive forces prevail, since the bridge elements 2, 3 are pressed against each other under load in the region of the upper flange 9. In the region of the lower chord 11, however, the bridge elements 2, 3 are pulled apart under load. Therefore, arranged on the lower flange 11 locking elements 4, 5 can absorb the resulting in the stress of the bridge 1 large tensile forces.

As in the following with reference to the FIGS. 5 and 6 is to be described, each of which is arranged on a lower flange 11 of the bridge elements 2.3 locking elements 4, 5 are designed such that they lock automatically when juxtaposing the bridge elements 2, 3 together. This allows the locking elements 4, 5 automatically latch together when unfolding the bridge 1.

The Fig. 5 shows the two locking elements 4 and 5 in the locked position. The locking element 4 has two locking pawls 16, 17 pivotally mounted about a common axis of rotation A and suitable for engagement with the respective other bridge element 2, 3. The opposing locking pawls 16, 17 form the legs of a locking pliers, which locks with the locking element 5 in the locking position. Via a spring 6, the locking element 4 is biased in the locking position such that the locking pawls 16, 17 are pressed against each other and tightly enclose the locking element 5. By the spring 6 contracts the executed as locking pliers locking element 4, it acts on the locking element 4 so with a force in the direction of the locking position.

The locking element 5 has a cylindrical locking bolt, which in the illustration in the Fig. 3 is encompassed by the locking element 4 in the locking position.

The locking element 4 also has a sloping guide 15. This is arranged on the outside of the locking element 4, which comes in the juxtaposition of the bridge elements 2 and 3 in contact with the incoming locking element 5. When juxtaposing the bridge elements 2 and 3, the locking elements 4 and 5 run against each other. Due to the oblique guide 15, the force acting on the locking element 4 during the incoming movement of the locking element 5 is divided into a component parallel to the inlet direction and a component transverse to the inlet direction of the locking element 5. The transverse component of this force acts counter to the biasing force of the spring 6 on the locking element 4 a. As a result, opens when entering the locking element 5 in the inclined guide 15 of the locking element 4, the locking element 4 automatically.

As soon as the locking element 5 has run into the locking pawls 16, 17 of the locking element 4 over the region of the oblique guide 15, the locking elements 4 and 5 latch automatically together and remain in the in Fig. 3 illustrated locking position.

To unlock the locking elements 4.5, a force against the bias of the spring 6 must be applied. For this purpose, the locking element 4 has an opening element 10. The opening element 10 has a rotary element 18 with an elliptical cross section, which is mounted pivotably about the center of the ellipse. In the locked position in Fig. 5 is the rotary member 18 oriented such that its major axis E is aligned parallel to the legs of the locking pliers.

To open the latch, the rotary member 18 is made of the in Fig. 5 shown locking position by 90 ° in the in Fig. 6 shown opened position rotated. This can be done by means of an attacking on the axis of rotation B of the rotary member drive or manually. For the drive-assisted opening of the lock, the unlocking drive 25, 26 can engage in a coupling 30 arranged on the bridge element 2, 3 which is connected to the opening element 10 via a shaft 29. In a bridge element 2, 3, in which the running surface is formed from track carriers, the coupling can be arranged on the inside of the track carrier, cf. Fig. 4 and Fig. 8 , Optionally, a lever 8 may be provided, which is connected to the rotary member 18 via the rotation axis B. In this case, the rotary member 18 can be rotated by pivoting the lever 8. In any case, the elliptical rotary element acts on the inner sides of the legs of the locking pliers during rotation into the open position. The legs are pressed against the biasing force and the locking pliers open. Thus, the locking element 4 releases the locking element 5.

Alternatively, the opening element may have an eccentric. The eccentric can be mounted on a shaft and act to open the lock on the locking element.

In the Fig. 7 and Fig. 8 the coupling region of the bridge elements 2 and 3 when unlocking the locking elements 4 and 5 is shown. The couplings 30 connected to the opening elements 10 are opposite to the locking position in FIG Fig. 4 rotated by 90 °. Through the opening elements 10, the locking elements 4 are both on the bridge element 2 as well opened at the bridge element 3. The locking elements 5 on both bridge elements 2 and 3 are released, whereby the bridge elements 2 and 3 can be pivoted against each other via the hinge 7.
