Description

Ship anchor with hydraulic assist

Technical Field

The invention relates to the technical field of marine equipment, in particular to a ship anchor with hydraulic assistance.

Background

The steamer docks at the anchor ground through the ship anchor, but because the seabed condition is comparatively complicated, the phenomenon that the ship anchor blocks and can't pull back appears sometimes, the crew can choose to abandon the anchor this moment, please refer to fig. 6, for the current ship anchor of living, this kind of hawse fixed connection is on the fluke, rethread on the anchor ring can break the round pin nail and change the atress direction, when anchoring, the atress direction is unanimous with the anchor eye direction, the round pin atress is less, when taking the anchor, if in the silt ground, the round pin atress to use the fluke root as the fulcrum, make the fluke turn out, if the anchor is blocked, the atress is great, break the round pin, the atress point shifts to the fluke root, directly pull out the anchor, greatly reduced the probability that the anchor is blocked.

However, because the force direction of the anchor is not completely consistent with the lifting direction of the anchor, the phenomenon that the anchor is clamped on the rock and cannot be pulled out still exists, on the other hand, the shear pin is a disposable product and is wasted, and if the shear pin is an inferior product or the specification of the shear pin is used wrongly, the risk of anchor failure exists, and potential safety hazards exist.

Secondly, under the condition that the texture of the seabed is soft, if the seabed encounters large wind waves, the anchor flukes can turn over soil and move along the direction of sea waves, the anchoring function cannot be realized, and certain potential safety hazards exist.

Referring to fig. 2, an elastic damping sleeve 13 with a thin top and a thick bottom is disposed on the inner wall of the pressing sleeve 5, a neck with a wide top and a narrow bottom is disposed at a corresponding position of the anchor arm 2, the surfaces of the elastic damping sleeve 13 and the anchor arm 2 are both rough, the pressing sleeve 5 is tightly attached to the back of the anchor arm 2 by the combined action of friction and the tension of the tension spring 7, and the force required for separating the pressing sleeve 5 can overcome the increase of the tension spring 7, so that the rotating arm 4 rotates to the other side.

Referring to fig. 3, the hinge point of the rotating arm 4 is closer to the root than the connection point of the tension spring 7 and the anchor arm 2, the included angle between the connection line from the connection point of the tension spring 7 and the anchor arm 2 to the head end of the anchor arm 2 and the connection line to the hinge point of the rotating arm 4 is less than ten degrees, the rotating arm 4 rotates by a small angle to stretch the tension spring 7 to the longest, and finally rotates in the other direction under the action of the tension force of the tension spring 7, and the second connecting rod 10 is fixedly connected with the anchor chain 3, so that the interference caused by the length is avoided by the bending of the anchor chain 3.

Referring to fig. 4, the hydraulic ejector 12 includes an elastic buffer cylinder 121 disposed inside the fluke 1 and a tree-shaped hydraulic passage 122, the elastic buffer cylinder 121 is expandable, when the anchor is initially taken down, the expansion of the elastic buffer cylinder 121 absorbs hydraulic oil brought by the rotation of the runner 11, an external accommodating cavity of the elastic buffer cylinder 121 is communicated with the outside of the fluke 1, the hydraulic passage 122 is equipped with a plunger 123, the plunger 123 is fixedly connected with a top plate 124, the high pressure in the elastic buffer cylinder 121 drives the plunger 123 to eject outwards, the outlet side of the plunger 123 narrows to avoid the sliding out of the plunger 123, and a spring is disposed to make the top plate 124 be located in a groove when not stressed, so as to avoid the sliding out interfering with the anchor taking down.

Referring to fig. 5, the fluke 1 is widened, the top plate 124 is a transverse rectangular plate, which increases the surface area, reduces the local pressure, and avoids inserting into the reef, the bottom of the top plate 124 is fixedly connected with at least three transverse plungers 123, which increases the ejection pressure of the top plate 124, the plungers 123 are perpendicular to the top surface or the bottom surface of the fluke 1, on one hand, the thickness of the upper surface is relatively low, the reef is more easily broken when the upper surface is pushed upwards, and on the other hand, the two ends of the top plate jointly have a pressure pushing outwards, so that the top plate can be pushed out before the reef is broken.

The working principle and the working process of the invention are as follows:

when the anchor is retracted, if the anchor is not clamped, the smaller acting force can turn over the soil at the moment, the anchor is pulled out, if the anchor is clamped, the acting force is increased along with the anchor lifting, the acting force is larger than the pulling force of the tension spring 7 and the friction force of the pressing sleeve 5, the pressing sleeve 5 is separated from the anchor ring 6, the rotating arm 4 rotates to the other direction, the acting force directly acts on the root of the anchor at the moment, the anchor is pulled out, if the anchor can not be pulled out still, the angle of the anchor chain 3 and the rotating arm 4 is changed by repeatedly loosening and retracting the anchor chain 3, the double-rod compression cylinder 8 repeatedly stretches when the second connecting rod 10 is driven, the oil pressure in the elastic buffer cylinder 121 and the hydraulic channel 122 is increased, the plunger 123 and the top plate 124 are ejected out, and the reef can be ejected or ejected to be cracked due to the fact that general rocks are compression-resistant and not tensile.

When encountering large stormy waves, if the anchor begins to turn over and move with soil, the rotating wheel 11 rotates along with the movement of the anchor, so that the double-rod compression cylinder 8 stretches and retracts, the top plate 124 is controlled to be ejected out, the resistance of the anchor in forward movement is increased, and the stormy wave resistance of the anchor is increased.
