Description

The design of a multifunctional cargo-passenger ship-pusher-amphibian refers to shipbuilding, in particular to the construction of new types of cargo-passenger ships for small rivers.

The construction of serial vessels for small rivers has practically ceased. It should also be noted that previously built vessels for small rivers (analogues) were specialized in designation: passenger ships, cargo ships, pusher tugs and towing and motor boats [1], [2], [3].

Built before the 80s of the last century, they are outdated morally and physically and decommissioned after the expiration of their service life. In addition, taking into account the “dying" of villages and other settlements along the banks of small rivers, cargo flows and passenger flows decreased many times. Therefore, the construction of new vessels for small rivers, specialized in designation, is unlikely to be profitable. At the same time, although reduced, cargo-passenger flows remained. As a solution, a device was proposed for a multifunctional cargo and passenger pusher vessel [4], adopted as a prototype and containing a hull, a passenger room, a hydraulic crane and a pushing device consisting of a towing collar, two hydraulic cylinders and pneumatic accumulators. A passenger ship was adopted as the prototype base vessel. Therefore, the cargo and the crane are placed on the deck of the superstructure, which is not rational in terms of stability. The peculiarity of small rivers is significant fluctuations in the fairway depth from the maximum normalized at rifts of 0.8 m to 0.5 m or less in the low-water period. Therefore, it would be highly desirable to be able to overcome rifts with a depth less than the draft of the vessel, and the possibility of independent "departure" and movement along the coast.

A device is proposed for a multifunctional cargo-passenger amphibious pusher vessel, comprising a hull, a ship power plant, a passenger room, a hydraulic crane and a pushing device consisting of a towing collar, two hydraulic cylinders and pneumatic accumulators, characterized in that the vessel has a cargo compartment, and as a ship power plant, a diesel-hydraulic circuit is adopted, consisting of the ICE-hydraulic pump complex, which drives the hydraulic drive through the distributor propellers, as well as the operation of the steering device, manipulator crane, pusher device and other mechanisms available on the vessel), the ship also has individually lowering chassis (at least four), the wheels of which have individual hydraulic drives with chain, cardan or gear transmission, and for lowering and fixing the chassis on the ship installed hydraulic cylinders and landing gear when they are lowered.

The device is illustrated in the drawing, which shows a diagram of the general view of the vessel (side view and deck plan). The device comprises a housing 1 with a room for passengers 2, a cargo compartment 3, the main engine 4, a hydraulic pump 5, a container with a working fluid 6, a pressure pipe 7, a distributor 8, a suction pipe 9, a drain pipe 10, a truck-mounted crane 11, a device for pushing, containing a towing bollard with a connecting cable and two hydraulic cylinders 12 with hydraulic accumulators, rowing hydraulic actuators 13, lowering chassis 14 with hydraulic cylinders 15 and hydraulic wheels 16, hydraulic wheels 17, for example, with chain transmission 18, legs 19, pushed barge 20, propellers 21.

The hydraulic circuits are controlled by sections of the control valve 8, while the crane has its own control valve that controls lifting, lowering, changing the reach and rotation of the boom, the working fluid to which is supplied from a common control valve 8.

The device operates as follows. First, using the crane 11, the cargo is received, then the cable mooring of the prefix barge is carried out. Then, using the hydraulic cylinders 12, the cable connection is tightened and the barge is placed in a symmetrical position relative to the diametrical plane of the pusher vessel. Pneumohydraulic accumulators installed in the system allow the barge-attachment to make some oscillatory movements with respect to the ship’s diametrical plane and waterline in the presence of excitement.

After connecting to the barge prefix, passengers are embarked and the vessel enters the voyage.

In the presence of shallow water with a depth less than the draft of the vessel using the hydraulic cylinders 15, the landing gear 14 is lowered and when the propellers 21 are working, the hydraulic drives of the wheels 17 are turned on through the distributor 8 and the wheels 16 are rotated through the chain drive 18. screws.

The present invention also allows for the loading and unloading of a pushed barge using its own means.

The presence of the lowering chassis 14 with hydraulic drive to the wheels will allow to overcome shallow areas with a depth less than the draft of the vessel, as well as “departure” and movement along the coast, i.e. the possibility of moving from the basin of one river to the basin of another river, which was previously carried out by "dragging" or towing on a sleigh with wheels. The technical effect of the invention is the expansion of functionality due to the main distinguishing feature - the lowering chassis with hydraulic wheels, which will allow the vessel to overcome shallow water, leave and move along the shore.

Such an expansion of functionality will allow the invention to be used both in the industry of the river fleet, and in the oil and gas production sectors, as well as in the armed forces.
