Folding pontoon-bridge segment

FIELD: transport.

SUBSTANCE: invention relates to stream-crossing expedients. Proposed segment comprises articulated medium and extreme pontoons with roadway built in deck. Medium pontoons transoms accommodate segment joint assemblies while extreme pontoon transoms support eye bolts and bypass units. Outer board of one of extreme pontoons is furnished with extending flexible folding sector-like floater consisting of inflatable wedge-like vessels arranged between frames. Said frames are fixed in recesses to turn about vertical axles mounted at the center of recess adjoining the roadway. Another extreme pontoon is equipped with rigid pod with length equal to that of pontoon pivoted to the latter to turn about axis parallel with segment lengthwise axis.

The invention relates to crossing-bridge means, and more particularly to a collapsible pontoons, ferries and pontoon bridges.

Know the pontoon element (see Pontoon Park special PPS-84. Book 1. The material part of the Park. Voenizdat, 1990, p.18-21, 2.1), including two medium and the hinge connecting the two extreme pontoon, one of which the pontoon is made with smooth rim, and the other pontoon with a rotating Radome.

The disadvantages of the known pontoon level are the large size and weight, impeding its air transport and for the transport by land requiring the use of cars increased weight.

It is also known pontoon link (prototype - see AB. St. No. 232779 from 23.09.1968, IPC B63B, CL 65A1, 8), comprising a rigid middle pontoon fitted on the transom joint nodes in the form of ear plugs with a rolling pin and pivotally United with him two extreme hard pontoon, equipped with pull-out from niches flexible plavuchesti.

The disadvantage of this pontoon link is the impossibility of the formation of floating bridges and ferries double-width and high payload.

The objective of the proposed technical solution is the empowerment of troops on the formation of bridges and ferries, equipped from folding pontoon units, improved the e transportable qualities of the links, including for transportation by air transport.

This goal is achieved by the fact that in a folding pontoon chain comprising pivotally interconnected average and extreme pontoons with built-in deck roadway, posted on the transom of the middle pontoon misbelieve butt sites, and on the transom extreme pontoons rinnie buttons and bypass the blocks, from the external side one of the outer pontoons are equipped with retractable from niches flexible foldable sectorwide type float, consisting of inflatable wedge-shaped containers, placed between the framework set forth in the niches can be rotated about the vertical axis established in the middle part adjacent to the roadway niches, and the other extreme pontoon equipped hard, equal to the length of the pontoon and mounted thereon rotatable about an axis parallel to the longitudinal axis of the folding pontoon link, fairing, made in the shape of a triangular prism, one side of which is in the upper position of the fairing, and the other face is in its lowest position are a continuation of the bottom contours foldable pontoon element, and a third side face of the fairing equipped butt devices is made, for example, in the form of ear plugs with a movable pin for pairwise connections of the links between a floating bridges and ferries.

The use of the Finance the proposed technical solutions will allow troops to form of folding pontoon links floating bridges and ferries of different capacity and improve transportable quality of the link, including air transportation.
