Description

[0002] CRANE SYSTEM USING PIPE HOOK [0003]

The present invention relates to a crane system using a pipe hook, and more particularly, to a crane system using a pipe hook capable of lifting a heavy object by using a pipe hook passing through a guide hole formed in a deck.

In general, marine structures are used for drilling and production of offshore oil and gas. Offshore structure is a structure to be installed on the sea or under the sea. It is classified into fixed type, semi-submerged type, floating type according to depth, and is mainly used for marine work such as exploration and extraction of energy source such as oil or natural gas . For example, an ocean platform fixed to the sea floor.

1 is a view showing a conventional ocean platform.

Referring to FIG. 1, a conventional marine platform 1 is formed by a plurality of decks D1 to D4 in a multi-layered structure. A flare boom 7, two or more large pedestal cranes Crane, 5) are installed. Generally, a crane is a device that lifts a cargo and carries it up and down, right and left, forward and backward, and is also called a crane. Among them, the pedestal crane (5) is installed on a ship or an offshore structure and carries out loading and unloading operations. These pedestal cranes (5) are capable of receiving heavy weights (W) of 30 tons or more.

However, even if such pedestal cranes (5) are installed in the marine platform (1), their use range is limited compared to their capabilities. Due to the complicated piping connections installed below the deck of the offshore platform 1, the pedestal crane 5, etc. can directly receive the weight W from the top deck D4 and the equipment in the lower deck D3 Lt; / RTI > Thus, pedestal cranes (5) can not be used even if there are numerous heavy objects such as Shut Down Valve (V) below.

There is a deck obstacle between the lower weight W and the pedestal crane 5 so that a monorail (not shown) may be separately installed on top of the shut down valve (V) in the range of 5 to 12 tons. Should be. Monorail weighing more than 5 tons is expensive, and manual handling is also difficult.

2 to 4, a crane system 100 using a pipe hook according to an embodiment of the present invention can lift a weight W under the lower surface of a deck 101 of an offshore structure. The crane system 100 using the pipe hook includes a guide hole 110 installed in the deck 101 of the offshore structure and a pipe hook 120 through which the heavy object W is connected to the lower end of the guide hole 110 And a pedestal crane 130 for providing a driving force to transport the weight W connected to the lower end of the pipe hook 120. In addition, the crane system 100 using the pipe hook according to an embodiment of the present invention may further include a detachable safety unit 140 for preventing the pipe hook 120 from falling.

Specifically, the crane system 100 using a pipe hook according to an embodiment of the present invention has a guide hole 110 provided in a through hole (not shown) formed in at least one deck 101 of the structure, A pedestal crane (130) is installed above the guide hole (110). A pipe hook 120 passing through the guide hole 110 is disposed and the lower end of the pipe hook 120 is connected to the heavy object W and the upper end of the pipe hook 120 is connected to the pedestal crane 130.

At this time, the heavy object W may be connected to the pipe hook 120 by a wire rope, and the pipe hook 120 may be connected to the pedestal crane 130 by a wire rope. A through hole is formed in the deck 101 so as to lift the weight W below the lower surface of the deck 101 of the offshore structure by the crane system 100 using the pipe hook, (101). The guide hole 110 is provided in such a through hole.

5 is an enlarged view of a part of a crane system using a pipe hook according to an embodiment of the present invention. FIG. 6 is a top view of a guide hole and a pipe hook of a crane system using a pipe hook according to an embodiment of the present invention. 7 is a view illustrating a safety unit of a crane system using a pipe hook according to an embodiment of the present invention.

5 and 6, the guide hole 110 includes a body 112 having a central hole h through which the pipe hook 120 passes, and a body 110 having a body hole 112 for fastening the body 112 to the deck 101 A fastening member 114 and rollers 116 for supporting the pipe hook 120 from both sides. When the pipe hook 120 vertically moves up and down the center hole h, the roller 116 assists the movement so that the pipe hook 120 can only be vertically moved. Here, sudden movement of the pipe hook 120 of the safety unit 140 can be suppressed in an emergency situation such as a sudden downward movement of the pipe hook 120, thereby preventing fall.

The pipe hook 120 is connected to the pedestal crane 130 at the upper end and can vertically move up and down. So that the guide hole 110 can be vertically moved only when the pipe hook 120 is vertically moved. The pedestal crane 130 is connected to the upper portion of the pipe hook 120 and the weight W is connected to the lower portion of the pipe hook 120. When the pedestal crane 130 is lifted by the pipe hook 120, Is raised. The pipe hook 120 may be formed of a steel material such as carbon steel, and thus has a very strong structure and is suitable for use in safety-conscious marine production facilities. In addition, a scale (not shown) may be displayed on the pipe hook 120 at predetermined intervals. The user of the crane system can instruct the lifting and lowering of the weight W safely while watching the scale indicated on the pipe hook 120. [ The pipe hook 120 can deform the terminal shape. For example, if the end portion of the pipe hook 120 is formed into a T-shape, various heavy objects W scattered around can be heard at one time. Further, an extension boom (not shown) or the like which can be detachably attached to the pipe hook 120 can be provided. In this case, the pipe hook 120 can be used simultaneously in various decks having different floors.

A pedestal crane 130 may be installed on the uppermost deck 101. The pedestal crane 130 lifts the pipe hook 120 to lift the weight W. Since the pipe hook 120 passes through the guide hole 110, the range in which the pedestal crane 130 can directly lift the weight W can be extended to the equipments in the lower deck 101.

The safety unit 140 serves as a brake in an emergency situation such as a sudden drop when the pipe hook 120 is vertically moved, thereby preventing movement of the pipe hook 120 and preventing the fall. The safety unit 140 may be detachably installed. The safety unit 140 is normally fitted in the groove of the guide hole 110 so that the pipe hook 120 can be stored in a correct position and prevented from falling during operation. 5 and 7, the safety unit 140 may include a safety bar 142 installed in the pipe hook 120 and a hook member 144 installed in the guide hole 110 . When the pipe hook 120 is dropped, the safety bar 142 is caught by the hooking member 144 to prevent movement of the pipe hook 120 to prevent falling.

The crane system 100 using the pipe hook according to an embodiment of the present invention may further include a controller (not shown) for controlling the pedestal crane 130. The controller controls the amount of unwinding and loosening of the wire rope of the pedestal crane 130 to control the operation of the crane system 100 using the pipe hook. In addition, the controller may be a wireless controller that controls the pedestal crane 130 wirelessly. That is, the pedestal crane 130 can be controlled by the operator wirelessly, and the crane system 100 using the pipe hook can be operated.

Such a controller can be implemented as a single module by means of software and hardware having a coded work program. Such a work program may be a program that can be executed by a computer, and may be implemented in a general-purpose computer that operates the program using a computer-readable recording medium. The computer-readable recording medium is implemented in the form of a carrier wave such as a ROM, a floppy disk, a magnetic medium such as a hard disk, an optical medium such as a CD or a DVD, and a transmission through the Internet. In addition, the computer-readable recording medium may be distributed to a network-connected computer system so that computer-readable codes may be stored and executed in a distributed manner.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, You will understand. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
