Abstract

FIELD: bridge and ferry. SUBSTANCE: bank part of pontoon bridging train has: - central and edge pontoons, hinged to each other in the area of high trances of their decks and bottoms; - gangway, hinged in the area of low trances of pontoons; - pontoon parts interconnecting units. Central pontoons have bottom canals from low trances side. Turning rods are placed in canals. Free ends of rods have joining units, made as an ear and a fork with locking bars. The bars have removable drives. Cantilevers with turning rods are mounted on the low trances of the edge pontoons. Turning rods are engaged with joining units of pontoon river parts.

Description

 The invention relates to bridge technology and can be used for guidance and operation of floating bridges and ferries.

 The coastal link of the pontoon-bridge park is known, consisting of two middle and two extreme pontoons pivotally connected to each other and equipped with folding gangways [1].

 The closest in technical essence and the achieved effect to the invention is the coastal link of the pontoon-bridge park, including middle and extreme pontoons, interconnected in the region of high transoms with deck and bottom hinges, gangways, pivotally hinged on the low transoms of the pontoons, and inter-link butt devices [ 2].

 A disadvantage of the known links is that being included in the park for forming shuttle ferries and coastal entrances of short bridges, they turn out to be superfluous when assembling bridges across wide water barriers, since they cannot be used in the river part of the bridge.

 The purpose of the invention is to increase the efficiency of the park by ensuring the use of the coastal link as a river link in the floating bridge and ferries.

In FIG. 1 - shows a link of a pontoon-bridge park in a transport position on a pontoon car, side view; in FIG. 2 is the same, arrow view in FIG. 1; in FIG. 3 - link in the open position, side view, prepared for use as a coastal link; in FIG. 4 - the same prepared for use as a river link; in FIG. 5 - link in the open position, in plan, view along arrow C in FIG. 4; in FIG. 6 - removable drive pin rod, the node I in FIG. 5; in FIG. 7 - attachment point of a removable pin drive on a plug flange, section DD in FIG. 6; in FIG. 8 - removable drive shaft of the rod fork pin, view E in FIG. 4; in FIG. 9 - attachment point of the removable shaft on the drive of the plug pin, section FJ in FIG. 8; in FIG. 10 - mounting the rod using a gangway, unit II in FIG. 4; in FIG. 11 - pin lock securing the gangway to the rod, view along arrow K in FIG. 10; in FIG. 12 - fixing the rod mounting rod and gangway, section LL in FIG. eleven; in FIG. 13 - a link as a coastal link of a bridge or ferry; in FIG. 14 - rod mounting in the profile channel of the middle pontoon, view along arrow M in FIG. thirteen; in FIG. 15 is the same, view along arrow H in FIG. 14; in FIG. 16 - a link as a river link in the river part of the bridge; in FIG. 17 is a flat rotary pin of a deck lock, section BB in FIG. 5; in FIG. 18 is a knot for attaching a flat pivot pin in the operating position, section BB in FIG. 17;
in FIG. 19 - shuttle ferry using two links; in FIG. 20 - re-docking of the shuttle ferry to enter the bridge line using the link; in FIG. 21 - a bridge of two shuttle ferries.

 The coastal link of the pontoon-bridge park includes two middle 1 pontoons and two extreme 2 pontoons connected in the high transom region by bottom hinges 3 and deck hinges 4. The middle 1 pontoons of the link on the low transom side are equipped with rotary rods 5 equipped with docking devices 6 and fork 7 with a removable drive pin 8 mounted on the flange 9 of the plug. The rods are equipped with brackets 10 for connecting them to the gangways 11 by means of a pin lock 12 fixed by a pin 13. On the transom of the gangway, a removable shaft 14 of the drive of the pin of the butt device inserted into the square recess 15 on the drive of the plug pin is placed. In the transport position and when the link is used as a coastal link, the swivel rods 5 are retracted into the bottom channels 16 and fastened with locks 17. The pin drive and the drive shaft are removed and fit into a transport storage niche (not shown in the drawing). The extreme pontoons of the link at low transoms are equipped with brackets 18 with flat rotary pins 19, interacting with the clams 20 of the tightening devices 21 of the river links. The flat pin is fixed in horizontal position by the pin 22.

 The work of the link is as follows.

 After unloading the link to the water, it automatically opens with gangways 11 raised up, the rotary rods 5 are fixed in the bottom channels 16 of the middle pontoons, the flat rotary pins 19 of the brackets 10 of the outermost 2 pontoons are turned down.

 To bring the link into working position, it is necessary to close the deck and bottom locks on the low and high transoms of the link, after which the link with the high transom is brought to the river link for docking and connecting the lifts (Fig. 13). In this form (gangways descend off the coast) the link is ready for use as a coast link in bridges and ferries.

 To use the link as a rack link, it is necessary to bring the steam with the link to the shore and use the hoists to raise its low transom above the water (Fig. 16). Lower the swing rods 5 (Fig. 4) to the lower position and fix them with the help of pin locks 12 (Fig. 11) similar to 11 (Fig. 10). Install the removable drive pin 8 (Fig. 6) on the flange 9 (Fig. 7) of the plug of the butt device and the removable drive shaft 14 (Fig. 8). Turn and fix the rotary flat pins of the low transom of the extreme pontoons to the working position (Fig. 17), install the removable tightening devices 21 (Fig. 16), after which the link is prepared for docking and work as a river link.

 When docking a link to a river link-section of a ferry bridge, it is necessary to use link lifts and removable tightening devices to level the sediments.

 Some loss of bridge displacement at the link section will be compensated by adjacent river links, and therefore, an increase in precipitation and bending moments in the river part of the bridge with the link, compared with the river part from river links, will be insignificant.

 The proposed link makes it possible to quickly use it in the coastal and river parts of bridges and ferries, which will increase the efficiency of pontoon parks. (56) 1. Guide to the Pontoon-Bridge Park PMP. Military Publishing House, Ministry of Defense of the USSR, M., 1965, p. 56, fig. 29.
