Description

The invention relates to shipbuilding, in particular, to anchor devices for the working movements of dredgers by pushing them to the feed with buried cables that do not impede navigation.

The purpose of the invention is to reduce the material capacity of the cable deaerator and simplify its design.

FIG. 1 shows a cable lid in the traveling (transport) position; in fig. 2 - the same, in an intermediate position; in fig. 3, - that in a working position.

The cable deaerator contains a movable beam 1, which is connected by a hinge 2 to the transom 3 of the hull of the dredger 4 and is equipped with a roller clutch 5.

The guide rollers 6 and 7 are attached to the deck 10 of the dredger 11 of the roller 6 by the bracket 8 made with the stop 9 at the point of descending of the buried cable in the upper position of the beam 1 offset relative to the longitudinal axis 12 of symmetry of the roller clutch 5 (Fig. 1), and is tangent to the circumference 13 of the roller 7 at the point of incidence of the recessed cable at the bottom

the position of the beam 1 is offset relative to the longitudinal axis 14 of symmetry of the roller clouse 5 (Fig. 3). Retainer

15 the upper position of the beam 1 is mounted on the bracket 8, and the latch

16 the lower position of the beam 1 - on the transom 3.

Clamps 15 and 16 limit the position of the beam so that its common center of body and core 17 is located in the direction of dumping the core from the vertical axis of the hinge 2. Anchor 17 is suspended on cable 18, at the junction of which the strut 19 is installed.

The storage of the crust in the field is carried out in pedestal 20 fixed to the transom 3 of the dredger body 4.

Treading works as follows.

From the traveling position (Fig. 1), the measles 17 can be lowered onto the ground at the location of the dredge 4 or fed to the motocaster 21 for laying a distance from the dredge

For lowering, the measles 17 rises from the pedestal 20 up to the stop of the thrust 19 into the roller cluses 5 by winding a cable 18 on the winch drum,

walking along the axis 12 of the roller cluster 5 of the circumference 11 of the roller 6, mounted in the bracket 8 on the deck 10.

The drive (not shown) lowers the retainer 15, after which the cable 18 is unwound, while the movable beam 1 rotates in a vertical plane around the hinge 2 under the action of its own weight and is kept from an arbitrary tilting on the thrust 19 (Fig. 2). Cable 18 from roller 6 moves to circumference 13 of roller 7 and axis 14. When the lower position is reached, the beam 1 stops with a stop-lock 16, and the measles 17 continue to descend until it reaches the bottom. After this, the dredger goes to the excavation area.

If it is impossible to directly lower the crust, for example, when the depth is insufficient, the measles 17 are fed to the moto wagon 21, where they are laid on the deck or suspended from the breech discharger at the moto dozer.

I

After receiving the core 17, the motor wind 21 begins to move forward while simultaneously releasing the cable 18 from the winch drum. Beam 1 is held on a tensioned cable by a roller clutch 5. Beam 1 is moved to its working position (Fig. 3) by slackening cable 18.

The lifting of the core is carried out by opening the anvil-latch 16 by a drive (not shown) attached to the transom 3, and a sample of the cable 18, while the beam 1 is rotated around the hinge 2 under the action of the tension of the cable. After stopping thrust 19 into roller clump 5, beam 1 rises around hinge 2 together with bark 17 until it stops 9 and the stopper 15 operates. After closing the stopper 15 by releasing the cable 18, the measles 17 are lowered into pedestal 20.
