Description

The utility model relates to the field of shipbuilding and concerns the means of motorization of pontoon parks, in particular towing and motor boats, and is intended for the engineering troops of the Ministry of Defense of Russia.

The inventive utility model has a multifunctional purpose and can be used, in particular, in towing and motor boats to ensure the movement of transport and bridge ferries collected from pontoon parks, guidance and maintenance of floating bridges from these parks.

A feature of the design of the floating devices of displacement small boats related to towing means (towing-motor boats) is the requirement for a quick and reliable connection of the boat with a towed floating means in conditions of different directions of flow and wind, as well as during waves. At the same time, it is important to ensure convenience for the crew when working with oil mechanisms and devices.

It is known that the fore nose device is made in the form of two consoles, each of which is pivotally connected to the hull and is equipped with a rotation mechanism made in the form of a helical brace pivotally connected to the console (“Pontoon Park special PPS-84. Book 2. BMK towing and motor boat -460. Technical description and operating instructions. "- M .: Military Publishing House, 1990, p. 8, 37).

The disadvantages of the known messenger device are the high complexity, duration and insecurity of manually translating the consoles from the transport position to the working position and vice versa, especially in conditions of wind waves or increased flow velocity. The disadvantages of the known flashing device can also be attributed to the rigid fixation of the consoles relative to the hull of the boat with the help of braces, at which the hinge point of the coupling lock is fixed, which in the conditions of rolling of the floating craft makes it difficult to connect the coupling lock to the coupling pontoon assembly and requires additional time to merge . An additional drawback is the transfer of force from the mooring nodes through the coupling lock to the rigid connection of the console - a helical brace, which leads to a significant mass of these elements.

It is known that the boat is equipped with a folding V-shaped frame, at one end of which there is a butt assembly for connecting to the boat, and on the other there are hinges and locks for steaming with the steam, each hinge made with stops placed below and above the axis of the hinges, which are perpendicular to the diametrical plane of the boat (patent RU 2059514 C1, priority, 12/18/1992, published 05/19/1996).

A disadvantage of the known flashing device is the presence of only one point of attachment of the frame to the hull of the boat, located in the diametrical plane, which in the conditions of independent rolling of the floating craft, especially when rolling onboard the boat (which has significantly greater amplitudes than the rolling of the ferry), causes significant forces to all nodes of the messenger device.

It is known that the towing motor boat is designed in the form of two rotary consoles with coupling locks and screw braces and containing two side struts and a right and left console, each of which is fixed with a finger-pin on the river link of the lag or shuttle ferry of the pontoon park (RU patent 2618578 C1, priority 05/12/2016, published on 10/27/1998).

A disadvantage of the known merging device is the inseparable connection of the coupling lock to the console, causing the use of additional equipment - the right and left consoles, which leads to an increase in the time required to prepare for the descent.

As the closest analogue, we selected a fore nose device containing two consoles, each of which is pivotally connected to the body using axles and is equipped with a coupling lock and a console rotation mechanism made in the form of a hydraulic cylinder, the body of which is pivotally connected via an axis to a bracket located on the nose boats. The supply of working fluid to the hydraulic cylinders of the console rotation mechanism is carried out from the boat hydraulic system via pipelines (patent RU 2183576 C1, priority 06/18/2001, published on 06/20/2002).

The disadvantages of the closest analogue are the rigid fixation of the console (bracket) due to the hydraulic cylinder relative to the hull of the boat, at which the hinge point of the coupling lock is also fixed, which in the case of swinging of floating boats makes it difficult to connect the coupling lock to the pontoon's assembly and requires additional time. An additional drawback is the transfer of force from the mooring units through the coupling lock to the rigid connection of the console - the hydraulic cylinder, which leads to a significant mass of these elements.

In addition, taking into account the rigid connections of the console with the hull, when connecting the boat to the pontoon, a semi-rigid mechanical system “boat-pontoon” is formed, which under operational conditions (different side and keel pitching, as well as changes in the draft of the pontoon during loading and unloading) causes considerable effort, acting on all nodes of the open device.

A technical problem, the solution of which is provided by the claimed utility model, is the creation of a new, universal design of the fore-gear of the towing-motor boat, which allows the hitching of the boat with pontoons of various types, increasing the safety of the work on the docking, reducing the labor and time for the boat to dock with the pontoon.

The technical result obtained by using the claimed utility model is to ensure the independence of lateral movements of the boat and the pontoon during rolling due to the presence of flexible connections that exclude the rigid fixation of coupling locks with brackets.

The technical result is achieved by the fact that the fore-end device of the towing-motor boat, containing two hinged brackets mounted to the boat hull mounted in the bow along its sides, and coupling locks, according to the utility model, each bracket contains a guide element located between its free and fixed ends, and the device is equipped with two mooring mechanisms, each of which contains a winch and flexible connection, designed to pass in the guide element of each bracket, etc. and this one end of the flexible connection is fixed in the winch, and the second is made free and having a tip made with the possibility of connection with a coupling lock.

Moreover, according to a utility model, the device is equipped with control mechanisms for the brackets, each of which contains a winch and a flexible connection, one end mounted on the bracket, and the other on the winch

Moreover, according to the utility model, flexible connections can be made in the form of chains.

Moreover, according to the utility model, flexible connections can be made in the form of cables.

Moreover, according to a utility model, the winch of the mooring mechanism is mounted on the deck between the brackets.

Moreover, according to the utility model, the winch of the bracket control mechanism is mounted on the bow rail.

Moreover, according to the utility model, one end of the tip can be made spherical, and the second can be made with a hole.

Moreover, according to the utility model, each guide element of the bracket can be made in the form of a cavity inside the bracket with two holes for the passage of a flexible connection.

Moreover, according to a useful model, the holes of the guide elements can be provided with gaps, one of which contains a recess for articulation with the spherical end of the tip.

The present utility model is illustrated by the drawings (Figs. 1-8), an example of the implementation of the side bow device of a towing motor boat on which, however, is not the only possible, but clearly demonstrate the possibility of achieving the claimed technical result. At the same time, the given example of the execution of the instant device does not limit the possibilities of implementing the utility model that do not go beyond the scope of the formula of the utility model, and are not exhaustive.

According to a utility model, the fore nose device of the towing-motor boat comprises two hinges of a bracket 2 pivotally connected to the hull 1 of the boat, mounted in the bow along its sides, and two mooring mechanisms. Each mooring mechanism contains a winch 3 and a flexible connection 4 (Fig. 1-7). Winch 3 is the main, traction.

Flexible connection 4 passes in the guide element 5 of the bracket 2, through the free end 6 of the bracket 2 and the fixed end 7 of the bracket 2. The guide element 5 of the bracket 2 is located between its free end 6 and the fixed end 7. The guide element 5 can be made, for example, in the form of a cavity made through in the bracket 2 for the passage of the flexible connection 4 with two output holes 8 and 9 located in the free end 6 and the fixed end 7 of the bracket 2. One end 10 of the flexible connection 4 is fixed in the winch 3 of the coupling mechanism, to Thoraya can be installed on the deck 11, between the brackets 2, and a second end 12 is free and provided with a lug 13 adapted to be connected with a clutch lock 14 (FIGS. 4-6). One end 15 of the tip 13 can be made spherical, and the second end 16 of the tip can be made with a hole 17 (Fig. 7).

The outlet openings 8 and 9 may be provided with closures 18 (side closures) located on the fixed end 6 of the bracket 2, and 19 (external closures) fixed on the free end 7 of the bracket, while the closure 19 may have a recess 20 of this shape (for example, spherical, conical, etc.) to articulate it with the spherical end 15 of the tip 13 (Fig. 7, 8).

The counting device is equipped with control mechanisms for the brackets 2, each of which contains a winch 21 (auxiliary) and a flexible connection 22. A flexible connection 22 with one end 23 is fixed to the bracket 26 on the bracket 2, and the second end 24 is fixed to the winch 21 mounted at one end on the bow guard rail 25 (Fig. 2-6). Flexible connections 4 and 22 can be made in the form of chains or cables (Fig. 1-7).

The inventive utility model works as follows.

The boat is unloaded from the pontoon car into the water and the brackets 2 are transferred from the transport position to the working position. To do this, the crew using the winch 21 releases part of the flexible connection 22, fixed to the bracket 26, and puts the brackets 2 in the outboard position, while their further folding overboard is due to gravity.

The brackets 2 are rotated relative to the axes 27 passing along the side of the boat in the working position. Then, with the help of the coupling locks 14, the boat is connected to the towed means, while using the quick-release connecting finger 28, the coupling lock 14 can be replaced with another coupling element (for example, a special pin for old-style pontoon parks).

After the coupling locks 14 are connected, the flexible connection 22 by means of the winch 21 is completely weakened, while the bracket 2 rests on the traction flexible connection 4. By selecting the traction flexible connection 4 by means of the traction winch 3, in which the traction flexible connection 4 passes inside the through cavity, through side clams 18 and external clues 19, the boat is pulled to the pontoon, in which tips 13 having external spherical surfaces enter the cavities of the external clues 19 of the through cavity of the bracket 2, which also have inner surfaces spans, which allows to provide the necessary mobility of the articulation of the coupling lock 14 with the bracket 2, as well as the ability of the boat to oscillate, independent of the landing and pitching of the pontoon.

At the end of the work and the release of the coupling locks 14, the brackets 2 are transferred using flexible couplings 4 and 22 to the transport position, and with the help of traction winches 3, the flexible couplings 4 are pulled through the through cavities until the tips 13 with the suspended coupling locks 14 are fixed in external closures 19 brackets 2.

The use of the claimed utility model will facilitate the work of the crew of the boat with brackets, reduce the time of transferring the brackets from the transport position to the working one and vice versa, and increase the safety of work when preparing the boat for use at the ferry, and also reduce the weight of the bow coupling device by reducing the loads acting at On the other hand, and the elimination of rigid fixation of the brackets to the boat hull, it will ensure the independence of boat and pontoon movements with the possibility of coupling with old pontoons about and a new sample.
