Description

Jack up system for barge

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jack-up system for a barge line for raising and lowering a barge line, and more particularly, to a jack-up system for a barge line capable of raising and lowering a barge line by providing a frictional force to the legs.

The present invention relates to a jack-up system for a barge, which is constructed such that a cylinder providing frictional force between a leg and a barge is stretched and contracted in the longitudinal direction of the leg so as to prevent breakage of the cylinder beforehand to improve durability.

The present invention relates to a jack-up system for a barge which enables a barge to be lifted and lowered without forming a weak portion such as a groove or a hole in the leg.

The barge is divided into pants and lighters depending on the application. A ship carrying goods between two points is called a porter, and a ship standing beside the main ship is called a lighter in order to load and unload goods when a large ship can not berth.

The hull is wide and the bottom is flat, and the structure is Western, Korean, eclectic, boxed, small wood (wood) and large (steel).

Some are fitted with propellers, but most of them are pulled by tugboats, and some pusher pants are pushed by mobs. The size is indicated by the cargo load, ranging from tens to hundreds of tons. A ship carrying a barge loaded with cargo is called a pants carrier, which improves the transport capacity.

Barges, on the other hand, are greatly influenced by maritime conditions in carrying out their duties. Accordingly, a jack-up system is provided at one side of the barge to raise and lower the hull to a height at which the wave can not reach, thereby maintaining a stable state.

For example, Korean Patent Laid-Open Publication No. 10-2012-0019638 discloses a jack-up house for a marine wind turbine installation dedicated line having a horizontally fixed cylinder and capable of raising and lowering a leg by generating a restraining force by inserting a part of the ring- Lt; / RTI >

EP 2275341B1 discloses a jack-up barge that has a plurality of anchoring elements protruding from the legs and a locking element formed in the cylinder, so that an anchoring element and a locking element are selectively engaged and constrained when the cylinder is expanded or contracted.

In addition, U.S. Patent No. 4,411,408 discloses that a plurality of points recessed on the outer surface of a vertical string are formed, and a pin is selectively inserted into a point outside the vertical string by a linear reciprocating motion, To perform the up / down function.

Finally, in U.S. Patent No. 8425155, a plurality of cylinders are sequentially extended or contracted, each cylinder is provided with a pin, and a hole is formed in the leg so that a pin can be inserted to perform a widening / lowering function A technique is disclosed.

However, the above-described conventional techniques have the following problems.

That is, all of the above-described conventional techniques must generate a latching force for a lifting / lowering action, and the restraining force is a structure by inserting a pin and a groove.

Therefore, such a groove or hole has a problem of lowering the strength of the leg, and the engagement and restraining structure by inserting causes damage to the parts such as the pin, so maintenance and repair are not easy.

In addition, since the cylinder for generating the braking force linearly reciprocates in the direction intersecting with the longitudinal direction of the leg or in the circumferential direction, it is not preferable from the viewpoint of safety due to frequent breakage of the cylinder due to large load and impact.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a jack-up system for a barge line for raising and lowering a barge line, and more particularly, Up system for a barge ship in which a barge can be raised / lowered.

The present invention is configured such that a cylinder that provides a frictional force between a leg and a barge is extended and contracted in the longitudinal direction of the leg to receive a force in a direction intersecting the direction of expansion and contraction of the cylinder so that breakage of the cylinder due to damage to the sealer is prevented Up system for a barge to improve durability.

The first fixing means includes a first fixed cylinder extending in the longitudinal direction of the leg, a first friction member for generating a frictional force in cooperation with the first fixed cylinder, And a force transmitting unit for urging the pusher to move in the leg direction.

And one side of the forcible transfer portion is provided with an inclined surface for forcibly guiding the first friction member in a direction orthogonal to the elongating and contracting direction of the first fixed cylinder when the first friction member is in contact with the one side of the first friction member.

And a second fixing means is provided at one side of the lifting cylinder to generate a frictional force by pressing the outer surface toward the center of the leg.

The second fixing means includes a second fixed cylinder extending in the center direction of the leg and a second friction member for generating a frictional force in cooperation with the second fixed cylinder.

In the jack abutment system for a pants line according to the present invention, a frictional force is applied to the leg when the cylinder is expanded or contracted, thereby providing a braking force when the barge is lifted or lowered.

Therefore, since there is no need to form a weak portion such as a groove or a hole in the leg, there is an advantage that efficient braking can be performed without lowering the durability of the leg.

Further, in the present invention, a cylinder for providing a frictional force between the leg and the barge is configured to expand and contract in the longitudinal direction of the leg.

Therefore, there is an advantage that the damage to the cylinder, which is generated when a force is applied in a direction intersecting with the direction of expansion and contraction of the cylinder, is prevented beforehand, thereby improving durability.
