DE102008015420A1 - Bridge segment for use by armed forces for transporting e.g. bridge supporting armor and/or vehicle, has hook, pin, projection, cross hole and fastening bolt connected to enable detachable connection between bridge segments - Google Patents

Abstract

The segment (1) has a plate shaped structure with two oppositely faced side wall regions (2, 3) extending towards a longitudinal axis of the bridge segment. The side wall regions are designed as upper and lower flanges. A hook (5), a pin (7), a projection (8), a cross hole (9) and a fastening bolt are connected to enable a detachable connection between the bridge segments. The hook is arranged at the front upper edge (4) of the upper flange, and the pin is arranged at the rear upper edge (6) of the upper flange.

Description

The The invention relates to a bridge segment and one of several such mobile bridge composable such identical segments.

to Preservation of tactical / operational mobility is attacking armed forces on special vehicles for overcoming terrain cuts and waters back to about 25 m wide. These Special vehicles, usually bridge-layer tanks or vehicles, are capable of using the laying device a bridge unfold and place on the jobsite. These module bridges are divided into larger modules to transport to simplify on the vehicle.

In the not before published DE 10 2007 001 778.4 a bridge laying system for longer bridge modules or bridge sections is described. A feed module integrated on the base vehicle / carrier has a main boom (laying bar) attached to it. When advancing the laying system, the feed module is moved to folding torque arms, whereby a large proportion of the reaction forces is introduced during the laying process in the bow area.

Bridge modules of several meters in length, which are stacked horizontally on a carrier or laying vehicle and then connected to each other at the front end during the laying process, are further from the DE 10 2004 016 983 B1 such as DE 10 2004 016 974 A1 known.

Of the present invention is based on the object, a laying bridge to reveal, which in a simple way with neighboring similar Make segments into a laying bridge, the individual bridge segments are much smaller Lengths may have as this in known Bridge modules is the case.

These The object is achieved by the features of claim 1 or 9 solved. Further, particularly advantageous Embodiments of the invention disclose the subclaims.

The Invention is based essentially on the idea of the laying bridge into smaller segments or segments (segment bridges or segments) Link bridges), the individual segments or links then are identical except for any ramps, so that Cost advantages arise in production, in use in the event of damage to individual components Segments easy replacement is possible (redundancy), facilitates handling due to the lower weight and in addition alternative loading options by vertical stacking or by rolling up. Each segment of the relocatable bridge preferably has the required bridge width, however only a fraction of the maximum bridge length or a known bridge module. Advantageously, a Division into 1 to 2 m wide segments.

there is a simple but solvable connection between the Involve segments. Accordingly, the single bridge segment plate-shaped with two opposite, itself extending in the direction of the longitudinal axis of the bridge Side wall areas, wherein the first side wall area as upper chord and the second side wall portion is formed as a bottom flange. For the frontal connection with the adjacent bridge segment funds are involved, providing a detachable connection between create this.

In a simple variant are front side at the upper edge of the Obergurtes a kind of hook arranged in the intended Use of the bridge segment a rear-bound Bolt of a front side equally adjacent bridge segment can engage. At the bottom wall forming side wall portion of the Bridge segment is a front longitudinally the bridge extending projection provided which Having a transverse bore, in the case of the intended Use the bridge segment one in the rear Area of the front side adjacent bridge segment arranged slidable safety pin can engage.

Preferably the side wall region designed as a bottom flange has a recess in which the front projection of the rear adjacent Bridge segment is insertable before the safety pin in the transverse bore is inserted, so that the individual bridge modules space-saving flush with each other are connectable.

Of the Bolts as well as the safety bolts can mechanically, for example via a lever arrangement or a linkage operated with a drive device or a disc become.

is a device-bound locking provided, the on the underside of each segment mounted drive means or disc to lock by about 90 ° to be rotated. The push rods are then used to actuate the bolts. To the disc can be provided with a central web on which the Disc can be rotated.

A manually operated locking is also possible. Here you can lock the segments be hooked near the upper edge with the fixed hook on the fixed bolt of the next segment, which is thereby charged almost exclusively on train and shear. On the bottom flange of the segment are the overlapping recesses, through which the dowel pin / bolt on the drive device or disc, which in this case only with the safety pin (dowel pin) must be in operative connection, is inserted, whereby this is also mainly loaded on shear and pressure.

The thus configured segmented laying bridges are mechanically simple, provide redundancy and simplification in handling. The smaller dimensions allow smaller ones Vehicles for transportation.

Further Details and advantages of the invention will become apparent from the following Based on figures explained embodiments. Show it:

1 the side view of a bridge segment according to the invention;

2 the bottom view of in 1 illustrated bridge segments;

3 the side view of three interconnected bridge segments according to the invention;

4 the bottom view of in 3 illustrated bridge segments;

5 a schematically illustrated laying vehicle when laying bridge segments according to the invention,

6 a device-integrated locking possibility of the bridge segments.

In the 1 and 2 is with 1 an example, 1.5 m wide bridge segment called. The bridge segment 1 is essentially plate-shaped and has two opposite, in the direction of the longitudinal axis 100 a side wall areas extending to be laid bridge 2 . 3 on, with the first sidewall area 2 as upper flange and the second side wall area 3 is designed as a bottom flange.

At the front upper edge 4 of the upper belt 2 is a catch 5 and at the rear-side upper edge 6 of the upper belt 2 is a can be brought into a functional position bolt 7 arranged such that when the intended use of the bridge segment 1 the hook 5 of the bridge segment 1 the bolt 7 a front-adjacent bridge segment 1 engages behind from above or below (see also 3 and 4 ). This will be the bolt 7 when using the finished bridge almost exclusively loaded on train and shear.

At the bottom strap 3 of the bridge segment 1 is a projection on the front 8th which is a transverse bore 9 has, and the rear side a sliding outwardly arranged fitting or securing bolts 10 provided, which in the intended use of the bridge segment 1 in the cross hole 9 the rear adjacent bridge segment 1 can be pushed in and loaded when using the bridge mainly on shear and pressure.

In this case, the lower flange 3 a recess on the rear side 15 into which the front projection 8th the rear adjacent bridge segment 1 is introduced before the safety bolt 10 in the cross hole 9 can be inserted.

The by a bolt guide 16 guided safety bolts 10 is mechanically via a lever 11 with a drive device 12 connected by means of which the safety bolt 10 automatically into the cross hole 9 can be inserted during the installation process.

In the following, a possible laying operation of the bridge segments according to the invention 1 with the help of 5 explained in more detail:
First, a first bridge segment 1 a segment magazine 13 a corresponding laying vehicle 14 For example, manually removed and in a support 20 with internal lock release ( 6 ) introduced. This is a disc 17 turned to lock by about 90 °, causing the bolts 7 . 10 by means of the on the disc 17 connected push rods 18 be operated. This can be the disc 17 with a central pier 19 be provided over which the disc 17 can be turned.

The individual widths of the bridge segments 1 then sum up the length of the required laying bridge. Due to the identical construction, different widths can be used and thus the length of the laying bridges can be individually adapted to the local requirements. The easy transport of different widths is achieved by the standing of the segments 1 in the segment magazine 14 of the vehicle 14 guaranteed.
