Description

The invention relates to a boom of a laying device, consisting of laying arm and boom, a bridge laying vehicle and a method for moving a boom of a laying device of a bridge laying vehicle in a vehicle transport position with the features of the preamble of claim 11.

The invention finds application, especially military, bridge laying vehicles that can transport and move bridge elements. As laying vehicles wheeled or tracked vehicles can be used. Laying vehicles generally have a laying arm, in particular front side is arranged on the vehicle, but can also be arranged on the rear side. The laying arm is used here for laying the bridge elements, with him the bridge elements can therefore be stored and resumed. In addition, such vehicles have a boom, which in particular is arranged at the rear of the vehicle, but can also be arranged at the front, if the laying arm is arranged according to the rear side. The boom usually has locking elements, such as a bolt lock, with which the bridge elements can be locked, lifted and held. Such a bridge laying vehicle is used for example in the DE 38 91 429 C1 , Especially in the reproduced there prior art, or the DE 197 01 650 C2 described. The booms are usually moved by means of an adjusting device, such as a hydraulic cylinder.

A disadvantage of the known embodiments is that only bridge elements of a single predetermined length can be transported and laid. Bridge elements of a different length can not be transported in particular because otherwise the center of gravity of the vehicle is moved together with the bridge element, so that driving in a stable position is not possible. For this reason, the laying vehicle must be matched together with the boom with the transported and to be laid bridge elements.

Another disadvantage is that modern armored vehicles additional armor, such as a mine protection, are mounted in the front of the vehicle, which shift the center of gravity of the vehicle. Thus, however, the installation device, consisting of laying arm and boom, must be adapted constructively, so that a subsequent attachment of additional armor on the vehicle is possible only at great expense, if not losses in stability, especially at the driving speed to be made.

Another disadvantage of known laying vehicles is that the boom protrudes upwards and backwards or forwards, so that a transport of the bridge laying vehicle, for example by means of a train, is made more difficult. This problem, and a possible solution thereof, are discussed in the DE 10 2005 041 493 B3 specified. The rear-side boom described therein can be brought into a vehicle transport position for the transport of the vehicle. The boom has a boom referred to as a rear arm, which is pivotally mounted on a designated as the rear frame body. The body is firmly connected to the vehicle. During the laying of a bridge element, the cantilever arm can be pivoted by means of a hydraulic cylinder. The cylinder is supported against a traverse, which is pivotally mounted on the base body, wherein during the laying of the pivoting movement is prevented by a bolt fixation. When the boom is brought into a vehicle transport position, the crossbeam can be lowered by means of the cylinder, so that the boom in the vehicle transport position has a smaller extension in the height direction with the same extent in the vehicle longitudinal direction.

A disadvantage of the described embodiment is that the cantilever arm can not be moved down sufficiently, since he is still articulated to the body. In addition, the transition to the vehicle transport position is very complex, since multiple bolts must be repositioned. Furthermore, a shift of the center of gravity for the inclusion of different bridge elements or in the provision of additional armor is not possible.

In the document DE 37 37 681 A1 a laying armor is described, which has a two-part arm on the rear side, wherein each of the two members is pivotable by a separate adjusting cylinder. However, this is not a boom for laying a bridge element, but an additional device, can be taken by means of bridge parts of a neighboring feeder vehicle and placed on the installation armor. The adjusting member moving the outer member of the pivoting arm is not supported on the inner member of the pivoting arm, but on the vehicle itself, at the same location as the inner member of the pivoting arm is supported. A decoupling of the movement of the outer member of the vehicle is not possible hereby.

The document US 4,023,226 A shows a laying vehicle, which has a tail boom at the rear, which is pivotable by means of a working cylinder supported on the vehicle. At the outer end of the tail boom, a coupling arm can be arranged by means of a locking element. However, this dome arm is not independently pivotable, so that the entire device has no increased mobility.

Similarly, an in FR 2 678 297 A1 described laying vehicle at the rear end of an arm which is pivotable by means of an adjusting device and at the outer end of a not independently pivotable dome arm is arranged.

It is the object of the invention to design a boom with increased mobility, for example, to move it better in a vehicle transport position.

The invention solves the task device with the features of claim 1. An inventive method for moving a boom in a vehicle transport position is characterized by the features of the characterizing part of patent claim 11. Advantageous developments are part of the dependent claims.

A basic idea of the invention is to pivotably arrange a pivoting body on the base body which can be fastened fixedly to the bridge laying vehicle by means of a fastening device, on which in turn the boom arm is pivotably arranged. By introducing this intermediate element, the boom according to the invention on two pivot axes, which give it a greater flexibility. This higher mobility is advantageous because thus different bridge elements can be laid and transported, in particular, the focus of the loaded bridge laying vehicle can be adapted to the transported bridge elements or to the additional armor. Furthermore, the device according to the invention makes it possible to bring the boom into a vehicle transport position, in which the dimensions in the vertical direction and vehicle longitudinal direction are significantly reduced.

For the pivoting movement of the swivel body relative to the base body of the boom has a swivel body adjustment device, in particular a hydraulic swivel body cylinder. In addition, he has for the pivotal movement of the boom relative to the pivot body, a, independent of the pivot body adjustment, boom arm adjustment, in particular a hydraulic Auslegerarmzylinder, which is supported at one end on the pivot body. The boom thus has two adjusting devices that are independent of each other and can be operated. The adjusting devices may for example also be designed as linear drives.

The Swivel body adjustment device should be supported with one end on the main body. Thus, a decoupling of the cantilever arm from the main body can be achieved by the provision of the intermediate pivoting body.

Thus, the load of the bridge elements in the bridge transport position of the tail boom is not completely on the swivel body adjustment, between the main body and the swivel body at least one strut, preferably two struts, are provided which carry the load of the bridge element. The struts can be performed with a pivoting movement of the swivel body relative to the base body via a guide slot. In the bridge transport position, the struts can be locked by means of a locking device, in particular by means of locking cylinders, so that the stability and safety is increased. The cantilever may also include sensors which detect the position of the pivoting body and / or the cantilever arm.

The boom can be brought into a vehicle transport position by the swivel body is pivoted by means of the swivel body adjustment device upwards, so that the boom can be pivoted by means of the boom adjustment from the pivot axis substantially forward in the direction of travel. Thus, the pivot axis of the cantilever arm can be brought over the base frame, so that the cantilever arm in the vehicle transport position with respect to the horizontal angle of + 30 ° to -30 °, preferably from + 10 ° to -10 °, can include. Preferably, the boom is in the vehicle transport position substantially in the horizontal.

Preferably, the pivot axis of the cantilever arm is raised so that it lies above a horizontal plane which extends through the highest point of the base body. Thus, the base body in the pivotal movement of the boom is no longer in the way. By raising the pivot axis There is also the advantage that the dimensions of the boom in the vehicle longitudinal direction can be reduced.

The vehicle transport position can be secured for safety by means of a fixing device, in particular by bolts.

In the vehicle transport position, the dimensions of the projection over the base body in the rear direction or front direction and / or in the height direction relative to a bridge transport position are thus reduced.

The boom can also be moved to a towing position. This is taken when the laying vehicle with loaded bridge elements is incapacitated and should be towed together with the bridge elements, for example, from a recovery tank. In the towing position, the jib and the bridge elements are no longer in the area of the towing bar and the recovery vehicle, so that towing is possible without danger.

Thus, the boom according to the invention fulfills, inter alia, the following functions:

1. 1. Secure the bridge in the transport position, taking into account the center of gravity.
2. 2. Coupling of two bridge elements in conjunction with the laying arm.
3. 3. Driving in a vehicle transport position.
4. 4. Driving in a towing position.

The Fig. 1 The cantilever 3 consists of three elements, namely a fixedly connected to the bridge laying vehicle 1 main body 5, a pivotally mounted on the body pivot body 6 and a pivotally mounted on the pivot body. 6 arranged on the cantilever arm 7 on both sides locking elements 18 are arranged with bolts for locking a bridge element.

The Figures 2 and 3 show the bridge laying vehicle, which transports two bridge elements 4.1 with a predetermined length X. The bridge elements 4.1 can be coupled to a bridge. The coupling process is in Fig. 6 shown.

This in Fig. 2 illustrated bridge laying vehicle 1 has in the front area a mine protection as additional armor, so that the center of gravity of the vehicle 1 relative to the in Fig. 3 shown vehicle without additional armor has moved forward. To compensate for this, the boom is in Fig. 2 controlled such that the bridge elements 4.1, in particular the upper bridge element 4.1, lie further in the direction of the stern. This allows the center of gravity of the loaded vehicle 1 back to the intended Position be brought so that the stability and safety while driving is guaranteed.

The boom 3 according to the invention also has the advantage that also bridge elements with a different length can be transported. This is in the FIGS. 4 and 5 shown. The bridge elements 4. 2 transported here have a length Y and can be laid individually, ie they do not have to be coupled. Even with the transport of the bridge elements 4.2, it is possible to shift the center of gravity, for example, if the Brükkenverlegefahrzeug 1 has an additional armor, as in Fig. 4 shown.

The boom 3 according to the invention is in the FIGS. 7 and 8th shown in perspective. It has a base frame 5, which can be fastened by four fastening devices 8 on the bridge laying vehicle 1. On the main body 5, a pivot body 6 is pivotally mounted. The pivoting movement of the swivel body 6 relative to the main body 5 is effected via a hydraulic swivel body cylinder 10 as a swivel body adjusting device. On the swivel body 5 of the boom 7 is pivotally mounted. The pivotal movement of the boom 7 relative to the pivot body 6 is effected by a hydraulic Auslegerarmzylinder 9 as boom arm adjustment. The boom cylinder 9 is connected at one end to the boom 7 and at the other end to the swing body 6. The swivel body cylinder 10 is connected at one end to the main body 5 and at the other end to the swivel body 6. On the main body guide rollers 21 and 22 are also arranged for the support and guidance of a lower bridge element ( Fig. 10 ).

In the FIGS. 7 and 8th is the boom 3 in a bridge transport position, the Fig. 3 equivalent. So that in this position, the load of the bridge elements 4.1 is not on the swivel body cylinder 10, 5 two struts 11 are arranged between the swivel body 6 and the base body, which can be locked by means of two locking cylinders 12. The struts 11 run as in Fig. 13 shown in a guide slot 13 of the main body. 5

In the FIGS. 9 to 12 various positions are shown, which can take the boom 3. The positions in Fig. 10 and 11 are taken during a transport or when laying a bridge element. In the Fig. 12 shown position is when coupling two bridge elements 4.1, as in Fig. 6 shown, taken. In the Fig. 9 shown position corresponds to the vehicle transport position, which is also in Fig. 1 is shown. To get into this vehicle transport position, the swivel body 6 is first pivoted by means of the swivel body cylinder 10 upwards. Thus, the pivot axis (A) of the cantilever arm moves upward. In the Fig. 9 is the pivot axis (A) above a horizontal plane (E), which passes through the highest point of the main body 5 fixedly arranged element. Thus, the cantilever arm 7 can be freely pivoted forward in the vehicle travel direction (F). It can assume a substantially horizontal position, specifically the angle of the extension arm 7 to the horizontal in the in Fig. 9 shown position is less than 10 °.

By the in Fig. 9 shown vehicle transport position results in a structure in which the boom 3 a reduced projection over the base body 5 in the rear direction (H) and height direction (G) against, for example, the in Fig. 10 or 11 Having shown bridge transport position.

In the vehicle transport position, the boom 3 by two in Fig. 14 illustrated bolt 16 can be fixed. For this purpose, the two struts 11 are inserted into a holding device 17, wherein the holding device 17 has bores through which a bolt 16 can be passed. The vehicle transport position is thus approached without manual intervention. Only the fixation in their position takes place by the staking out of the two bolts sixteenth

The positions of the pivot body 6 and the boom 7 are determined by the in Fig. 15 monitored sensors 14 and 15, so that the different positions can be approached by a bridge control without a security risk.

The Fig. 16 shows the bridge laying vehicle, which is towed together with the charged bridge elements 4.1 by a recovery armor 50 by means of a towing bar, wherein the boom 3 is in the towing position, in which the pivoting body is pivoted particularly high.
