Universal pontoon link

 

(57) Abstract:

The invention relates to crossing-bridge means, more specifically to the ferries and pontoon bridges. Universal pontoon link contains pivotally interconnected two middle and two at the pontoon with integrated roadway, misbelieve butt sites, made in the form of plugs and ear and installed on both the transom link, folding gangways, forming a folded position flat roadway of the bridge, and turning mechanism is similar. The mechanism of rotation of each plank is made in the form of a torsion shaft bilateral twist, set in sleeves in Skhodnya, when one end of the shaft attached to the gangway by the end of the lever with the latch and lock straps with emphasis, and the other end connected figured fork with your finger pontoon, and the width of one of the extreme pontoons reduced so that the width of the link equal to the width of the river link with the translated down the fairings two-lane floating bridge. Universal pontoon link can be used in two-lane floating bridge and it has a high reliability by simplifying the design of the turning mechanism is similar. 10 Il.

The invention relates acquisition is the creation of a universal pontoon link reliability while simplifying the structure of the rotation mechanism similar to its application in two-lane floating bridge.

The solution of the stated problem is achieved by the fact that the universal pontoon link contains pivotally interconnected two middle and two at the pontoon with integrated roadway, misbelieve butt nodes installed on both the transom link, folding gangways, forming a folded position flat roadway of the bridge, and turning mechanism similar to that performed for each plank in the form of a torsion shaft bilateral twist, set in sleeves in Skhodnya, when one end of the shaft attached to the gangway by the end of the lever with the latch and lock straps with emphasis, and the other end connected figured fork with your finger pontoon, and the width of one of the extreme pontoons reduced so that the width of the universal link equal to the width of the river link with the translated down the fairings two-lane floating bridge across the deck.

The reliability of the rotation mechanism similar to the declared level will rise by at least 40%. In addition, universal pontoon link can be used in river and coastal parts of the two-lane floating bridge, which provides for the Assembly of this type of bridge kit pontoon Park PPS-84 increase its length up to 144 m (provided that the replacement be the mi links, longitudinal section; Fig. 2 - universal pontoon link placed on the deck gangway, views of the coastal transom of Fig. 3 - universal pontoon link in river part two-lane floating bridge, views of the coastal transom of Fig. 4 - way floating bridge with universal pontoon link, located in the coastal part of the plan; Fig. 5 - two-lane floating bridge with universal pontoon units, located in river and coastal parts of the plan; Fig. 6 - universal pontoon link with hinged gangway, side view; Fig. 7 - turning mechanism gangways at the pontoon of Fig. 8 - turning mechanism gangways middle of the pontoon of Fig. 9 is a cross section along a-a in Fig.7; Fig. 10 is a view along arrow B in Fig. 7.

Universal pontoon link 1 contains pivotally interconnected two medium 2 and two at 3, 4 of the pontoon with integrated roadway, misbelieve butt sites, made in the form of a fork 5 and the ear 6 installed on both the transom link, folding gangways 7, forming a folded position flat roadway of the bridge, and turning mechanism is similar.

The mechanism of rotation of each plank 7 made in the form of a torsion shaft 8 two-way twist, set in sleeve, the support bars 12 with the stop 13, and the other end of the shaft is connected figured fork 14 with the finger 15 of the pontoon 2 or 3. A torsion shaft 8 is set so that in the open and closed positions gangways 7 the force of his spin against the forces of gravity. Width at pontoon 3 is reduced so that the width IN1the proposed link 1 is equal to the width of the IN2river link 16 translated in the lower position of the fairing 17 two-lane floating bridge. This gangways 7 and the length of the torsion shaft 8 of the pontoon 3 is reduced in comparison with the similar nodes in the middle of the pontoon 2.

Transportation universal pontoon links by land is folded on the car.

The claimed device operates as follows.

Universal pontoon units 1 and river links 16 unloaded from cars to water and after opening use them to build a single-track or double-track floating bridges.

When assembling single floating bridge universal pontoon parts and river links are connected to the ribbon using misbelieve butt node - fork 5 and the ear 6. At universal pontoon units, located on the river side of the bridge, plank 7 leaves placed on the deck and in the links of the second exercise mechanism, the force of the spin torsion bars 8 which allows you to perform this operation two pontoon.

When assembling the two-lane floating bridge universal pontoon units 1 pristykovyvayas river links 16, pre-connected to each other with the butt of the sites hosted on turned down the fairing 17. Thus far the pontoons 3 universal pontoon parts 1 facing toward the longitudinal axis of the bridge. Universal pontoon units, located on the river side of the bridge, plank 7 leaves placed on the deck, and the links used to pair floating bridge with banks, gangways 7 throw back to the shore.

After the troops crossing the floating bridge disassemble the parts, put them and upload to the car.

Universal pontoon link containing pivotally interconnected two middle and two at the pontoon with integrated roadway, misbelieve butt nodes installed on both the transom link, folding gangways, forming a folded position flat roadway of the bridge, and turning mechanism similar to that performed for each plank in the form of a torsion shaft bilateral twist, set in sleeves in Skhodnya, PR is rum, and the other end connected figured fork with your finger pontoon, and the width of one of the extreme pontoons reduced so that the width of the universal link equal to the width of the river link with the translated down the fairings two-lane floating bridge on the deck.
