Description

The invention relates to systems for the roots of floating berths and structures.

The root connection is known, since (5 hundred of a root rope and damped, its element is 1.

The disadvantages of the well-known root connection are the bulkiness, the large weight and the comparatively high cost of its design.

The purpose of the invention is damping.

dynamic load and weight reduction of the root bond.

The goal is achieved by the fact that, in a ballast containing a core cable and a damping element, the latter is made in the form of a cylinder filled with water, on the side surface of which is a barrel. There are no through holes, inside of which there is a piston with a return spring and holes, connected by means of a rod with a sub-sliding eye, in this case a removable cover with holes is made on the upper part of the cylinder, and a fixed eye is on the bottom.

FIG. Figure 1 shows schematically the root linkage with the damping element, a general view, the dotted line shows the state of the root linkage in the absence of an external load; in fig. 2 - damping element in the composition of the root bond; in fig. 3 - design of the damping element; in fig. 4 - the same plan view; in fig. 5 shows section A-A in FIG. four.

: Anchor connection I consists of a chain (cable), between the bows of which a damping element 2 is mounted, made in the form of a cylinder 3, on the side surface of which through holes 4 and 5 of different diameters are provided, and inside is water 6, a spring 7 with a return spring 8, holes 9 connected by means of rod 10 with a movable eye 11. At the top of cylinder 2 there are removable cover 12 with holes 13 for moving water, hole m 14 for rod 10, holes 15 for bolts 16 with nuts 17 In the lower part of the cylinder 3 there is a fixed eye 18. Inside and the cylinder 3 has guides 19 protecting the piston 7 from seizing and a working projection 20 limiting the movement of the piston 7. An auxiliary eye 21 can be mounted on the side surface of the cylinder 3, to which the float 23 is fastened with the eye 22 and connecting brackets 25

The anchor connection works as follows.

Under the action of a dynamic load (jerk), the force is transmitted to the eyes 11 .4 18 of the damping element 2. From the eye 1, the force is transmitted to the force 7. Overcoming the resistance of the return spring 8 and the water 6, you press the last of cylinder 3 through the holes 4 , 5, 9, and 3, the piston 7 with the rod 14 and the eye 11 begins to move; it moves out of the cylinder 3. The speed of movement depends on the size of the orifice P1 m and the apparent force. Elastic resistance of the water 6 to the movement of the piston 7 is ensured due to the change in the velocity of its movement within the cylinder 3. This is achieved by appropriate arrangement and size of the holes 4, 5, 9 and 13. So at the initial moment of action the resistance The water content is comparatively insignificant as it squeezes through all the openings of parts j, 9 and 13. As the piston 7 moves, the total area of the holes for water 6 out of the cylinder 3 becomes smaller, therefore the resistance to movement of the piston increases.

If water 6 is out of the working part of cylinder 3 (it is completely displaced before the end of the stretching force, then the movement of bed 7 is limited by the working lug 20. In this case, the return spring 8 is maximally compressed. After the jerk in the main link has passed decreases sharply and can be equal to zero. Under the action of the return spring 8, the rim 7 with a snubber 11 returns to its original position. The absorption energy of the damping element m 2 of the root bond 1 depends on the current response Piston displacement and bore areas 4,5, 9 and 13.

If necessary, it is advisable to include two or more damping elements in the core communication.

In the event that the damping element is close to the bottom ground, in order to avoid clogging its openings, the latter is placed at a distance of at least 1.0 m or bottom to the float.

The economic effect of the basic connection depends on the depth of installation, gauge. root connection and magnitude jerk. So, if a damping element is inserted into the same core link instead of a suspended array, then the cost of one enneogetic unit (order) is reduced in 3-6 D depending on the caliber and depth.
