Description

Flexible rods 5 are connected to the TC 2 and to each other by means of jumpers fixed on its sections and distributed along its entire length 7. Each jumper 7 has a base 8, which is directly attached to the TC section 2. Under the terms of mounting and dismounting of operations, such a base 8, as shown in Fig. 2, is expediently performed in the form of a detachable sleeve with symmetric radial beam-like protrusions. The sleeve is fixed to the TC 2 by crimping its sections. All the jumpers 7 during installation operations are fixed to the TC 2 so that the symmetrical beam-like protrusions are ps in the same vertical plane, i.e. directly under each other.

At each end of the beam-like protrusion of the base 8 is mounted on a pivot axis 9 parallel to the axis of the sleeve of the base 8, a plug 10, the slot of which is oriented vertically. 8, slots of the plug 10 on the pivot axis 11, perpendicular to the pivot axis 9, a wheel 12 is installed. A groove 13 is made in the rim of the wheel 12, the profile corresponding to a semicircle with a dielectric large diameter of the groove 5.

A carrier 14 is attached to the horizontal rotary axis 11, which, for example, can be made, as shown in FIGS. 2 and 3, in the form of two symmetrical and parallel trims or, as shown in FIGS. 4 and 5, in the form of a U-shaped bracket . Drove

14 is able to freely rotate on the axis 11 in the plane of the wheel 12. At the free end of the carrier 14 between the straps (FIGS. 2 and 3) and, or in another embodiment, a second same wheel with a groove 17 is mounted inside the bracket on the horizontal rotary axis 15. The wheels 12 and 16 are in contact the edges of their rims with the possibility of their free rotation on their axes 11 and

15 or are located relative to each other with a small gap significantly smaller than the diameter of the flexible link 5. Between the grooves 13 and 17 of both wheels 12 and 16, the flexible link 5 is skipped.

To simplify and speed up assembly operations when a flexible rod 5 is installed between the chutes of the wheels 12 and 16, the carrier 14 is equipped with a quick coupling with the axle 15. The quick coupling can be made, for example, in the form of transverse slots 18 in the slats or sides of the U-cut bracket 14 The slot 18 is made in width corresponding to the diameter of the seats

axis 15, with an expanding entrance to facilitate insertion into the slot 18 of the axis 15.

According to the significant diameters of the wheels 12 and 16, when using flexible rods 5 with a large diameter of the bar or side of the bracket 14, in the places where the wheels 12 and 16 are mated, the widths are no less than the diameters of the wheels 12 and 16. This prevents the flexible bar 5 from entering its bend between the edges of the rims of the wheels 12 and 16. With small diameters of the wheels 12 and 16 and flexible r 5 (the flexibility of r 5 increases significantly), it becomes advisable to perform on the inner side surfaces of the strips or carrier 14 ledges 19 with lateral circular milling mi coaxial with wheels 12 and 16 (Figs. 4 and 5). The protrusions 19 in height are made so that they extend between the rims of the wheels 12 and 16 to a depth corresponding to the thickness of the edges of the rims of these wheels. This prevents jamming of the flexible rod 5 between the rims of the wheels 12 and 16 and (or) a violation of the integrity of its surface.

The device operates as follows.

When the spatial configuration of the TC 2 is changed under the influence of an incoming water flow due to the onset or change in the nature of the movement of the watercraft 1, as well as under the influence of irregular deep currents and other factors, an interconnected change in the spatial configurations of the flexible rods 5 occurs. and the reduction of other flexible wires 5, which are constant and in tension, as well as a change in their spatial position (oscillation) in within the limits of TC 2, limited by jumpers 7. In addition, changes in the elongations of the flexible rods 5 are also caused by changes in the tension of the winches 6, if necessary, targeted changes in the spatial configuration of the TC 2 and tensile loads on it under the weight of its own weight. In this case, the flexible links 5, interacting with the jumpers 7, force the wheels 12 and 16 to rotate, between the grooves of which they are located, as well as the forks 10 to rotate on the axles 9. Due to the fact that the wheel 16 is mounted on the carrier 14 with the possibility of rotation the latter on the axis 11, the conditional line connecting the centers of the rotation axes 11 and 15 of the wheels 12 and 16 will always be perpendicular to the corresponding section of the flexible tag and 5.

located between the grooves of the wheels 12 and 16, which prevents the possibility of local clamping and bending.

The impact (pressing) of the flexible link 5 on any of the internal surfaces, including the protrusions 19 of the strips and the sides of the bracket 14, causes the fork 10 to rotate in the corresponding direction, while the flexible rod 5 rests (rests) in the trough of one of the wheels 12 or 16 and interacts with him. Thus, thanks to the self-alignment of the fork 10 with the carrier 14, each bending of the rod 5 is practically constant
