Description

The invention relates to shipbuilding, in particular, to the design of the ship's heave calm.

The purpose of the invention is to improve the reliability of the pitching pacifier by allowing the separate operation of the hydraulic cylinders.

The drawing shows the damper pitching of the vessel.

The damper contains a feather 1 of the ruler with a baller 2 and supports in the form of a moving bearing 3 and a stationary bearing 4, which is pushed into position from the niche 5 of the ship’s hull, the pull-out power drive in the form of two hydraulic cylinders 6 with rods 7, a rudder actuator (not shown) ), the control system of the pen extension cylinders (not shown). The end part of the niche 5, located in the hull of the vessel, contains seal 8 of baler 2 and two seals 9 of rods 7 and is connected along the perimeter with guides 10 of movable carriage 11 and two guide edges 12 of locking pin 13 of baller 2 about the axis in the idle position of ores. In the upper part, the puller 2 contains a rigidly mounted cam half coupling 14. The second coupling half 15 is freely and biased on the puller 2 and is connected to the tiller 16 of the transfer actuator (not shown). The movable carriage 11 is connected with the rods of 7 hydraulic cylinders 6.

The pitching pusher works as follows.

The rudder is extended by feeding the working fluid into the upper (rod) cavity of the hydraulic cylinders 6. At the same time, the rods 7 of the hydraulic cylinders 6 tons of the yoke carriage 11 along the directions 10 towards the ship's side. The carriage 11 for the upper part of the puller 2 pushes - (pushes) the steering wheel out of the niche 5.for the ship into the working position. The cams of the coupling half 15 and 14 are engaged, the clamp 13 releasing the puller from fixing. In working position, the puller 2 keeps the tiller 16 from turning.

The rudder is cleaned by supplying the working fluid to the lower (rodless) cavity of hydraulic cylinders 6. At the same time, the rods 7 of the linders 6 push the carriage 11 along the guides 10 into the side of the vessel. The carriage 11 for the upper part of the puller 2 pulls the steering wheel into a niche 5.

I / .. . The transfer of the steering wheel is carried out

in the working position, in which the half coupling 14 rigidly mounted on the baller 2 is connected to the coupling half loosely mounted on the balloon 2 by a tiller 16. A two-sided forks 13 slides along two guiding ribs 12 and the balloon 2 is fixed against rotation around its axis in the non-working positions of the steering wheel and the steering wheel is released from fixation in the working position.
