Description

SUBSTANCE: inventions relate to ferry-bridge means, and more specifically to motorization of pontoon-bridge parks.

In general, the state of the art of solutions in the field of motorization and control of ship platforms of various types using propulsion and steering systems includes a wide range of proposals, in particular, for example, inventions related to offshore platforms containing at least one hull equipped with orientable power installations distributed on this body and, in particular, below it and associated with the means of controlling the orientation and actuation of the propulsion systems.

Typically, these controls are actuated by a control operator to control not only the direction of movement, but also the speed of movement of this platform in a given direction.

It is known that platforms of this type are also equipped with special features to stabilize the position or influence the environment of the platform in order to repel objects, such as blocks of ice or other objects, and to avoid collision with them and even damage to the hull.

Thus, an invention is known that discloses devices, systems and methods for operating a marine vessel, drilling underwater wells and extracting hydrocarbons from them. The sea vessel contains at least two coordinated pairs of controlled azimuth thrusters for moving the vessel on ice in case of changes in ice drift or other conditions and keeping the station in a reservoir containing pack ice. In one embodiment, a corresponding pair of azimuth thrusters is provided. In one embodiment, the propulsors have a common physical axis of rotation, and in another embodiment, each propulsion device has its own physical axis of rotation. In another embodiment, the azimuth propulsion devices are controlled by an automatic control system with a feedback loop. In yet another embodiment, the vessel is substantially elongated with a centrally mounted tower with mooring lines that can be detached from the vessel (US Patent 8398445 (B2), IPC B63H20/08; B63H 5/125, publication 2013-03-19).

Also known is an offshore platform (1) containing at least one body (2) equipped with orientable power plants (3, 4, 5, 6) distributed on it, and means (7, 8, 9, 10, 11) of attitude control and actuation of these power plants. The control means include means (12) for displaying at least a part of the water surface around the offshore platform (13) near it, associated with means (14, 15, 16, 17, 18, 19, 20, 21) for controlling the operation of at least parts of orientable power plants (3, 4, 5, 6) to create and direct the flow of water towards this part of the surface. Zones that form touch-sensitive keyboard control panels for power plants are located around the entire platform (1). Control means (14, 15, 16, 17, 18, 19, 20, 21) contain means (22) for storing orientation and power control data of each power plant and means (22) for storing orientation and power control data for each power plant (RU patent 2656750 C2, IPC B63H 25/42, B63B 35/08, B63B 35/44, B63B 43/18, published: 06/06/2018).

The platform is also equipped with means for controlling the orientation and actuation of these orientable propulsion systems, and in the figure these means are indicated by the general position 7.

As is known, these control means 7 contain a control unit, indicated by the general position 8, associated with the means forming the human/machine interface used, for example, by the operating operator, which are indicated by the general position 9 and contain, for example, an orientation control lever, indicated by the general position 10, and the power control knob, indicated by the general position 11.

This allows the control operator to control the maneuvers of the platform, in particular its direction and its speed.

However, the control of these platforms is extremely complex, and the controls require a sufficiently long response time, which can lead to a danger to the platform, which is unacceptable in the case of motorization of pontoons as part of a pontoon-bridge park.

A device for fixing an outboard engine is known (see A.S. USSR No. 198950, IPC B 63 h; class 65 f ¹ , 4/20; 1967, BI No. 14, p. 176), containing two shells hinged to each other , brackets and base board.

The disadvantages of the known device for fixing the outboard engine are the impossibility of its installation on the pontoons of pontoon-bridge parks and the inability to compact transportation on vehicles.

It is also known a device for mounting the motor (see. Set of bridge building tools KMS-E and diesel hammer DM-240 with a single-boom headframe OSK. Technical description and operating instructions. M.: Voenizdat, 1981, p. 59, 60), containing a frame , transom board and shelf.

The disadvantages of this device for hanging the motor are its unsuitability for installation on pontoons of pontoon-bridge parks and compact transportation on vehicles.

A device for mounting an outboard motor is known, shown in Fig. 1 (Patent RU 2244659 C2, IPC B63H 20/06, published: 01/20/2005) . The device consists of a collapsible spatial structure 1, which is attached to the bow of the pontoon pontoon 2 of the pontoon-bridge park and on which the outboard motor 3 is attached.

The use of this technical solution, according to the authors, will make it possible to install an outboard motor on a pontoon, both on the transom and in the bow, and provide motorization of the pontoon, as well as compact transportation on vehicles by folding the device for hanging the outboard motor into the transport position, while the volume occupied in this position will decrease by 3 times.

The disadvantages of this design include the following:

- low degree of readiness of the device, the device must be assembled from separate elements, attached to the bow of the pontoon, and an outboard motor must be installed on it, after that a fuel line and wires for connecting to the battery must be connected to the outboard motor;

- the inconvenience of controlling the outboard motor, the motor is located at a distance from the bow of the pontoon and its upper part is at deck level;

- limited angle of rotation of the motor;

- lack of regular places to accommodate the fuel tank and battery;

- lack of adjustment of the height of the outboard motor relative to the level of the pontoon deck.

The problem of motorization and control of the pontoon as part of the pontoon-bridge fleet lies in the need to create such a method for their implementation and the design of the propulsion and steering unit for implementing the method, which would provide the ability to quickly transfer technical equipment from the transport position to the working position, simplify installation operations and control the pontoon in part of the pontoon-bridge park when building crossings.

The technical result is aimed at eliminating the above disadvantages and consists in simplifying the motorization and increasing the maneuverability of the pontoon control while ensuring optimal propulsion depth at different pontoon drafts.

The specified technical result is achieved by creating a method for motorizing and controlling a pontoon as part of a pontoon-bridge park, characterized by the fact that

two propulsion and steering units are preliminarily installed and fixed on the side traverses of the pontoon, one on each traverse,

produce a given optimal deepening of the propellers of the propulsion and steering units at different values of the pontoon draft,

the horizontal axes of the propellers of the propulsion and steering units are oriented by turning them at a given angle around the vertical axis in the range of 0° - 360°, the movement of the pontoon is controlled during simultaneous or sequential operation of the propulsion and steering units.

In addition, the installation and fixation on the side traverses of the pontoon of two propulsion and steering units is carried out from the transport position from a special pallet.

Also, the specified technical result is achieved by a propulsion and steering unit for controlling a pontoon as part of a pontoon-bridge park, containing an outboard motor and a device for attaching an outboard motor to a pontoon, in that the device for attaching an outboard motor to a pontoon contains a device that can be installed and fixed on the pontoon side beam a frame having a vertical guide with a carriage mounted on it, to which a swivel fork with a trim plate is hinged, on which an outboard motor is fixed, while a hydraulic station is installed on the frame to move this carriage along the said vertical guide, and the steering mechanism of the outboard is located on the carriage itself motor.

In addition, a fuel tank, an outboard motor remote control, fuel cans, and an outboard motor steering wheel are additionally installed on the frame.

In addition, the battery is additionally installed on the carriage.

The essence of the inventions is illustrated by drawings, which show:

The embodiment of the propulsion and steering system shown in the drawings and an example of its installation and use on a pontoon are shown primarily for illustrative purposes and should not be construed as limiting the scope of claims.

The motorization of the pontoon 2 (see Fig. 2) is carried out using two propulsion and steering units (hereinafter referred to as DRU) 1. Pre-installed and fixed on the side traverses 3 of the pontoon, two propulsion and steering installations 1, one on each traverse 3, produce the specified optimal deepening of the propellers 4 DRU 1 at different values of the draft of the pontoon 2, the horizontal axes of the propulsors 4 DRU 1 are oriented by turning them at a given angle around the vertical axis in the range of 0° - 360°, after which the movement of the pontoon 2 is controlled with simultaneous or sequential operation of the DRU 1.

DRU 1 (see Fig. 5, 6) for controlling the pontoon as part of the pontoon-bridge park, contains an outboard motor 5 and a device for attaching the outboard motor 5 to the pontoon 2. The device for attaching the outboard motor 5 to the pontoon 2 contains on the side traverse 3 of the pontoon 2 frame 6 having a vertical guide 7 with a carriage 8 mounted on it, to which a rotary fork 9 with a trim plate 10 is pivotally attached, on which the outboard motor 5 is fixed, while a hydraulic station 11 is installed on the frame 6 to move this carriage 8 along the mentioned vertical guide 7, and on the carriage 8 itself there is a steering mechanism 12 of the outboard motor 5.

A fuel tank 13, a remote control 14 of the outboard motor 5, fuel cans 15, a steering wheel 16 of the steering mechanism 12 of the outboard motor 5 are additionally installed on the frame 6.

The battery 17 is additionally installed on the carriage 8.

Such a set of features of the proposed technical solutions provides a simplification of motorization and an increase in the maneuverability of the pontoon control while ensuring optimal deepening of the mover at different pontoon drafts. At the same time, the problem of quickly transferring technical means from the transport position to the working one, simplifying the installation operations and managing the pontoon as part of the pontoon-bridge fleet when crossings are being built, is being solved.

The work of the DRU is carried out as follows.

To move the pontoon 2 in the desired direction by rotating the steering wheel 16 of the steering mechanism, the required position of the swivel fork 9 and the outboard motor 5 relative to the pontoon in the horizontal plane is ensured. The design of the DRU provides the possibility of rotation of the outboard motor 5 by 360° and the movement of the pontoon 2, both with a log (see Fig. 3) and a shuttle (see Fig. 4).

The hydraulic station 11 is necessary to drive a hydraulic cylinder (not shown), which moves the carriage 8 along the vertical guide 7 of the frame 6 to the desired position. This makes it possible to ensure optimal deepening of the outboard motor 5 with different drafts of the pontoon 2, depending on the degree of its loading (Fig. 7, 8).

The battery 17 is a source of electrical energy to ensure the operation of the hydraulic station 11, start the engine of the outboard motor 8 using a starter from the remote control 14 and other consumers of electricity.

Using the remote control 14, in addition to starting/stopping the outboard motor 8, the speed of rotation of its propeller (propeller 4) is also controlled.

Two DRU 1 are stored and transported on a special pallet 18 (see Fig. 9) in full readiness for work. The installation of DRU 1 on the pontoon 2 from the transport vehicle is carried out using a crane-manipulator installation or other lifting equipment (see Fig. 10). This achieves the minimum time to transfer DRU 1 from the transport position to the working position.

Thus, the proposed inventions ensure the achievement of a technical result, which consists in accelerating and simplifying motorization, as well as increasing the maneuverability of controlling the pontoon while simultaneously ensuring optimal deepening of the mover at different pontoon drafts.
