Implementation of the utility model.

The anchor winch of the pontoon park contains a drum 1 with a cable 2, mounted with the possibility of free rotation on the main shaft 3, supported by liners 4 mounted in the holes of the frame 5.

On one side of the drum 1, on the outer side of the frame 5, a direct transmission gearbox 6 is mounted, in the housing 7 of which a direct transmission shaft 8 is vertically, with the possibility of free rotation. At the end of the direct transmission shaft 8, a bevel gear 9 is rigidly mounted, which engages with a bevel wheel 10 mounted on the coupling half of the drum drive 11, which in turn is mounted on the side surface of the drum 1 with the possibility of free rotation around the main shaft 3. In addition, inside the housing 7 of the direct drive gearbox 6, on the main shaft 3, on splines 12, with the possibility of axial movement , the drive half-coupling of the drum drive 13 is installed.

On the other side of the drum, a worm gear 14 is installed. On the shaft of the worm gear 15, facing the drum 1, on splines 12, with the possibility of axial movement along the shaft of the worm gear 15, the drive half-coupling 16 of the safety clutch 17 is installed. mounted on the end of the main shaft 3 facing the side of the worm gearbox 15.

On the right and left on the drum body 1, with the possibility of free rotation around the drum body 1, on the clamps 19 vertically upwards, levers 20 are symmetrically installed, on top of which there are lugs 21 of an annular section. In the eyes 21 with its ends, with the possibility of free rotation, a rod 22 is mounted, made in the form of a cylinder. In this case, the end of the cable 2 goes around the bar 22 from above.

On the surface of the levers 20 facing the rear wall of the niche 23 of the link of the pontoon park, rods 24 are pivotally mounted. At the other end, the rods 24 are passed inside the springs 25 mounted inside the guides 26 installed on the rear wall of the niche 23, and fixed from the ends of these springs 25. In this case, the springs 25 are made in such a way that the force for their compression is slightly less than the force required to break the cable 2.

On the collar 19, installed from the side of the worm gear 14, in the direction of the rear wall of the niche 23, a small lever 27 is made, at the end of which an earring 28 is made. In the earring 28, a vertical rod 29 directed downwards is pivotally mounted. To the lower part of the vertical rod 29, the clutch drive lever 30 is pivotally mounted, which, with its other side, is rigidly mounted on the sleeve 31, mounted on the bracket 32, mounted on the worm gear housing 14. On the sleeve 31, orthogonally upwards, the fork 33 is mounted, enveloping the outer surface of the drive half-coupling 16 safety clutch 17. On top of the fork 33, on the inside, on both sides, there are crackers 34 of cylindrical shape, included in the groove 35, made around the circumference of the leading half-coupling 16.

Anchor winch pontoon park works as follows.

To freely bleed the cable 2, the drum 1 is driven by a direct drive gearbox, for which the drive half-coupling of the drum drive 13 is moved along the axis of the main shaft 2 and thereby it is disconnected from the driven half-coupling of the drum drive 11. The cable 2 is unwound to the required length and its end is fixed with anchors (not shown in the figures) and select the sagging part of the cable 2 by rotating the drum 1 using the direct gear 6. Further tension of the cable 2 is carried out by rotating the drum 1 with the worm gear 14. To do this, move the drive half-coupling of the drum drive 13 in the direction of the driven half-coupling of the drum drive 11 until they are closed, and thereby connect the drum 1 to the main shaft 3. In this case, the safety clutch 17 is in the closed position and the torque from the shaft of the worm gear 15 is transmitted to the main shaft 3.

The cable 2 is tensioned until the required position is reached by the link of the pontoon park. After that, due to the worm gear of the worm gear 14, arbitrary rotation of the drum 1 is excluded.

With increased wind waves, currents, uncontrolled bending of the floating bridge or when heavy equipment enters the link of the pontoon park, the link of the pontoon park is displaced in the direction orthogonal to the longitudinal line of the cable 2. In this case, the rod 22 perceives the longitudinal forces arising in the cable 2 and seeks to move down the levers 20, and the rods 24 tend to compress the springs 25. If the longitudinal forces arising in the cable 2 exceed the compression forces of the springs 25, the levers 20 move down, the clamps 19 rotate, and the small lever 27 rises, dragging the rod 29 with it. the edge of the clutch drive lever 30, which in turn rotates the sleeve 31. At the same time, the sleeve 31 deviates to the side the fork 33, which moves the drive coupling half 16 towards the worm gearbox 14 with crackers 34, disconnects the safety clutch 17 and disconnects the main shaft 3 from the shaft of the worm gearbox 15. At the same time, they ensure the rotation of the drum 1 pa free issuance of tr wasp 2 and remove the resulting critical force.

After removing the force, the springs 25 open and push the rods 24 forward, which in turn return the levers 20 to their original position, which return the clamps 19 to their original position. In this case, the clamp 19 moves the small lever 27 down, which in turn pushes the rod 29 down, and she, in turn, moves down the edge of the clutch drive lever 30, mounted on its lower end. The clutch drive lever 30 turns the sleeve 31, which in turn deflects the plug 33 in the opposite direction. Fork 33 moves the drive half-coupling 16 towards the driven half-coupling 18 and closes them together. Thus, the arbitrary rotation of the drum 1 is again excluded.

The specified technical result, which consists in preventing the anchor winch cable from breaking, is achieved due to the possibility of disconnecting the main shaft 3 from the shaft of the worm gear with a safety clutch 17, which is disconnected by moving the drive half-coupling 16 towards the worm gear 15. side in the groove 35, made along the outer surface of the leading coupling half 16, and the other end rigidly mounted on the sleeve 31, which is rotated by moving the clutch drive lever 30 with one end rigidly mounted on the sleeve 31, and the other end pivotally mounted on the rod 29, which in turn, it is mounted on a small lever 27 made on a clamp 19. In this case, the movement of the small lever 27 is carried out by turning the clamp 19 due to the movement of the levers 20 when the cable 2 acts on the rod 22 and when longitudinal forces occur in the cable 2 exceeding the compression force of the springs 25 spring shock absorber ov, the rods 24 of which are pivotally mounted on the levers 20, and the guides 26 are mounted on the pontoon wall of the link of the pontoon park.
