Abstract

A pump tower reinforcement device is disclosed. A reinforcing device according to an embodiment of the present invention is mounted on a pump tower including a plurality of pipes for introducing or discharging liquid cargo into and from a cargo hold and a connecting member for connecting the pipes to each other on the inner surface of the pipe, A circumscribing wrap; And a support member connecting the catching portions to each other.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pump tower,

The present invention relates to a reinforcement device for a pump tower.

A ship for transporting a liquid cargo such as liquefied natural gas (LNG) or the like is provided with a cargo window for storing liquid cargo liquefied at a cryogenic temperature and a pump tower for loading and unloading the liquid cargo.

The pump tower has a filling pipe connected to the loading device for introducing the liquid cargo into the cargo hold, two discharge pipes connected to the unloading device for discharging the liquid cargo to the outside of the cargo hold, One emergency pipe used for cargo unloading and a connecting member connecting these pipes to each other. The connecting member can be connected to each pipe with a truss structure.

The pump tower is typically installed close to the aft side bulkhead and is supported by a base support provided at the bottom of the cargo hold in a fixed condition to a liquid dome. Here, the discharge pipe is disposed closer to the inner wall of the heat insulating barrier formed on the side of the partition wall than the emergency pipe.

The pump tower is provided with a base plate that is coupled to the base support at the bottom. The filling pipe, the discharge pipe, and the emergency pipe of the pump tower are fixed to the base plate, and the base plate is coupled to the base support.

On the other hand, a sloshing load occurs in the pump tower due to the coincidence of the period of motion of the liquid cargo in the cargo hold with the period of motion of the external wave load. If the pump tower is deformed due to the sloshing load, it may also affect the liquid dome, the base support, and the base plate, so it is necessary to effectively cope with the sloshing load.

Conventionally, a pump tower considering a sloshing load in the most serious situation was manufactured and applied regardless of the type of the cargo hold.

In this case, the connection member for connecting the pipe of the pump tower is excessively used for reducing the sloshing load, which increases the weight of the entire pump tower, the manufacturing cost, and the installation manpower and installation time. Further, since a large amount of connecting members are connected to the pipe of the pump tower by a welding method, the stability of the pump tower may be lowered.

As a related art, refer to Korean Patent Laid-Open No. 10-2012-0013255 (2012.02.14.

Korean Patent Laid-Open No. 10-2012-0013255 (2012.02.14. Open)

An embodiment of the present invention is to provide a pump tower reinforcing apparatus which is mounted on a pump tower and can effectively reduce a sloshing load.

According to an aspect of the present invention, there is provided a piping system including a plurality of pipes for introducing or discharging a liquid cargo into a cargo hold, and a pump tower attached to an inner outer surface of the pipe and connecting the pipes to each other, An inclined portion surrounding the periphery; And a support member for connecting the subcontracting portions to each other.

The inner side of the engaging portion may be opened so as not to interfere with the connecting member when sliding along the pipe in order to change the installed position of the reinforcing device.

The fixing device may further include a fixing plate provided on the inner side of the inclining portion in a shape corresponding to the pipe shape to fix the reinforcing device to the pipe and a fixing portion provided on the fitting portion to closely contact the fixing plate with the pipe .

The fixing portion includes a case provided outside the inclusion portion, a rotation driving portion screwed to the inside of the case, and a pressing portion pushed downward by the rotation driving portion according to the rotation direction of the rotation driving portion, .

The fixing part may further include a fixing latch inserted into the through hole of the case and supported by the lower portion of the rotation driving part inside the case, and a rotation bar rotatably coupled to the upper part of the rotation driving part and coupled to the fixing latch .

A spring member that is coupled to the lower portion of the fixed catch under the through hole so that the fixed catch can not be released out of the case through the through hole and a fastening means coupled to the fastening catch to support the lower portion of the spring member .

And an interval adjusting plate attached to the inner surface of the inclining portion to adjust an interval between the engaging portion and the fixed plate.

The reinforcing apparatus may further include a diagonal connection member that is provided in two or more stages and connects the subcontracting portion of the upper reinforcing device and the subcontracting portion of the lower reinforcing device to each other in a diagonal direction.

The reinforcing device of the pump tower according to the embodiment of the present invention can be mounted on the pump tower to effectively reduce the sloshing load.

In addition, considering the characteristics of the sloshing load acting on each type of cargo hold of the ship, one or more installed or installed positions can be changed in a certain portion of the pump tower, thereby effectively reducing the sloshing load.

In addition, since no separate welding work is required during the installation work, not only the stability of the pump tower can be improved, but also the weight and the installation workforce and time of the pump tower can be reduced.

The effects of the present invention are not limited to the effects mentioned above, and other effects not mentioned can be clearly understood by those skilled in the art from the description of the claims.
