Description

FIELD: inland navigation.

Known pushed sectional soy. Tanks with automatic or semi-automatic coupling of barges (sections), equipped with powerful stern propulsion and steering complexes (DRC) are known.

The disadvantage of driving such compositions is their low controllability and, as a result, increased requirements for the dimensions of the track "

Closest to the present invention is a method of driving bendable pushed trains with active thrusters on the bow section. By controlling both the stern and fore DRC, as well as the force-bending devices, complex maneuvers can be carried out when passing the winding fairway

The disadvantage of this method is the difficulty of control, since in addition to affecting the feed and nasal DRC, the skipper must simultaneously control the bending device (s) under the conditions of izv. sheet fairway, this causes unavoidable control errors at the most crucial points of posting, which limits the number of sections of the bent composition to a minimum (two sections). The complexity of control does not allow the implementation of multilink flexible sectional compositions (MISS) with more than two sections,

The purpose of the invention is to improve the management of MISS.

This goal is achieved by the fact that, according to the driving method of the multilink bend sectional composition, they create a pull force forward along the course, and additionally create a pull force back with a force of up to 0.1 - 0.3 of the force pull force forwards.

Despite the power costs in the braking mode of the aft section, the total resistance of the composition is reduced, which provides an increase in speed or an increase in the carrying capacity of the composition without increasing its power consumption.

nosti. This happens for two reasons. Firstly, the nasal thrusters operate in a counter flow with more high efficiency. Secondly, the constant unwinding tension in the composition gives it elastic properties, which contributes to the formation of oscillatory motion set by the nasal section. A traveling wave effect occurs when each subsequent section strictly repeats the movement of the previous one, as a result of which all sections of the composition are in the associated flow caused by the nasal section. It is easy to control the feed section, the warning roll of the composition, since in this case the entire feed section becomes the steering wheel of the composition. This eliminates the need for a force-bendable composition, the sections are securely joined by simple shnirnye couplings, and the number of sections can be substantially increased without managing the composition . In straight sections, the stretching of the composition excludes its yawingness, which contributes to a decrease in resistance.

MISS contains a bow energy section 1, equipped with a bow DRC 2, cargo sections 3 with couplings 4 and a feed energy section 5 with a DRC 6 (FIG. 1). Coupling 4 has support hinges 7 on the lead section 8, a spherical hinge 9 on slave section 10 (fig. 2). The extremities of sections 8 and 10 have matched semi-cylindrical formations (FIG. 3) with a minimum gap defined by pitching bar on the maximum wave in this pool (figure 5). lugs 11, covering the hinges 7 (FNG „3) and eyelet 12, covering the hinge 9, are installed th on the axial bearing 13 (Figure 4).

The hitch 4 with the hinges 7 and 9 provides vertical and angular movement of the extremities of the sections relative to each other on the waves within the gap between them (figure 5). In addition, the semi-cylindrical extremities ensure that the section on the hinge 9 rotates relative to each other.

up to 3 ° C, which ensures free bending of the composition without any force devices. Control of ATP 2 and 6 on the fore and aft ends 1 and 5, any composition maneuvers can be carried out.

An example of the method

On the Ob reservoir, a semi-circular MISS model was tested, consisting of eight sections with dimensions: 4.6 m; 1.5 m; T 0.3 m. The total length of the composition is 40 m. “The total capacity of the bow and stern DRC is 10 kW o

On the tests, the bow DRC worked in the forward mode, and the stern DRC - in the reverse mode. The composition showed the ability to move without a yaw at the forward course, providing movement along a tortuous section not less than 1.5 times the width of the section and a turning radius not less than 2 section lengths. The turnaround was carried out by the management of the bow DRC. When driving along the winding section of the stern aerial recovery zone, it was used as an active thruster when the power consumption in the reverse mode was up to 0.1 - 0.3 times the power of the bow DRC,

The required form of the train in the plan was reliably provided by the bow and stern DRC, while the yaw and rolling of the section were almost completely excluded, and the train was similar to the control of a ship with an active thruster.

Measurements of the compositional speed show that the compositional speed with the stern DRC operating in reverse mode is 10% higher than the compositional speed without the aft DRC

The proposed method of driving the MISS makes it possible to bring the number of sections of the bendable composition to 6-8, without complicating the controllability of the composition. At the same time, the speed of the train can be increased or, which is the same, the power ratio of the train can be reduced. Despite the exclusion of forced bending of the train, it can pass along difficult twisting and narrow sections of the track with a turn radius of at least two section lengths and a width not less than one and a half width section.
