The support rail 200 may include a first rail 210 and a second rail 220 and the first rail 210 and the second rail 220 may be spaced apart from each other and extend in opposite directions . 1, the first rail 210 extends along the left side of the lower part of the drilling derrick 100 and the second rail 220 extends toward the right side of the lower part of the drilling derrick 100 Can be extended.

The first rail 210 and the second rail 220 are spaced apart from each other and a driving unit 300 to be described later may be installed in a spaced space formed between the first rail 210 and the second rail 220 . Also, the drilling equipment supported by the drill derrick 100 or moved up and down can be transferred to the lintel through the space between the first rail 210 and the second rail 220.

3, the support rail 200 may be provided along the width direction of the drill derrick 100 in a plurality of directions. In other words, the support rail part 200 is symmetrically installed on the front and back surfaces of the drill derrick part 100, so that the drill derrick part 100 can be supported more stably.

The first rail 210 is disposed below the first derrick part 110 to support the first derrick part 110 and the first derrick part 110 can move along the first rail 210. Similarly, the second rail 220 is disposed below the second derrick part 120 to support the second derrick part 120, and the second derrick part 120 is disposed along the second rail 220 Can be moved.

The driving unit 300 moves the drilling unit 100 to adjust the height of the drilling unit 100. The lower ends of the first derrick part 110 and the second derrick part 120 can move in opposite directions on the support rail part 200 according to the operation of the driving part 300. [

Since the first derrick part 110 and the second derrick part 120 are directly or indirectly coupled to each other so as to be rotatable at the upper end thereof, the height of the drilling derrick 100 can be adjusted according to the operation of the driving part 300, When the derrick 100 moves, the first derrick part 110 and the second derrick part 120 rotate in opposite directions with respect to the upper end, and thereby the first derrick part 110 and the second derrick part 120 120 may move in opposite directions along the support rail 200.

The driving unit 300 may include a first hydraulic cylinder whose one end is coupled to the head part so as to lift the head part 130 of the drilling unit 100. The first hydraulic cylinder may be installed on a deck or a drill floor, and the first hydraulic cylinder may be coupled to the head part 130 of the drilling derrick part 100 at one end. The first hydraulic cylinder can be lifted or lowered by extending or contracting the head part 130 coupled to the first hydraulic cylinder.

FIG. 1 shows a state in which the drill derrick 100 maintains a maximum height (hereinafter, referred to as 'first drill derrick'). FIG. 2 shows a drill derrick 100, (Hereinafter referred to as " second state of the drilling derrick part ") in which the height of the drilling derrick part 100 is lowered.

The drill derrick 100 may move according to the operation of the driving unit 300 and change from the first state to the second state or from the second state to the first state. For example, when an offshore structure or a drill ship or the like equipped with the derrick structure 1000 passes through the height restricting zone, the drill derrick 100 may change from the first state to the second state so as to maintain the second state, Conversely, when supporting various equipments etc. for the drilling work or for transferring to the sea floor or recovery from the sea floor, the drilling derrick part 100 can maintain the first state.

The process of changing the drilling derrick 100 from the first state to the second state will be described in detail with reference to FIGS. 1 and 2. FIG.

If the first hydraulic cylinder coupled to the head part 130 of the drilling derrick 100 is contracted and the head part 130 is lowered by the operation of the drive part 300, The first derrick part 110 and the second derrick part 120 of the derrick part 100 start to rotate in opposite directions about the upper end. At this time, the first derrick part 110 rotates in a clockwise direction and the second derrick part 120 rotates in a counterclockwise direction with reference to FIG.

The lower ends of the first derrick part 110 and the second derrick part 120 rotate in opposite directions about the upper end of the first derrick part 110 and the second derrick part 120, 1 < / RTI > rail 210 and the second rail 220 in opposite directions. At this time, the lower end of the first derrick part 110 and the lower end of the second derrick part 120 move away from each other.

Accordingly, the height of the drill derrick part 100 can be adjusted.

That is, the driving unit 300 descends the head part 130 of the drill derrick 100 so that the height of the drill derrick 100 is lowered. When the head part 130 is lowered, And the second derrick part 120 are rotated at the upper end and separated from each other at the lower end, so that the respective structures can move without interference. The first derrick part 110 and the second derrick part 120 are moved along the support rail part 200 and are supported by the support rail part 200 while the height of the drill derrick part 100 is adjusted , The load of the drill derrick part 100 can be dispersed, so that the overall height of the derrick structure 1000 can be adjusted more stably.

Further, as the height of the drilling derrick part 100 is lowered, the center of gravity of the marine structure or the ship where the drilling derrick part 100 is installed can be lowered, so that a more stable offshore structure or ship can be realized.

The derrick structure 1000 according to an embodiment of the present invention may further include a stopper portion 400. The stopper portion 400 may include a first derrick And is installed in the support rail 200 so as to limit the moving speed of each lower end of the part 110 and the second derrick part 120.

The stopper part 400 restricts the abrupt movement of the lower end of the first derrick part 110 and the lower end of the second derrick part 120 along the support rail part 200, The lower end of the first derrick part 110 and the lower end of the second derrick part 120 can be supported by applying an eccentric force opposite to the moving direction.

The stopper block 400 may include a stopper block 410 and a second hydraulic cylinder 420. The stopper block 410 may include a lower end of the first derrick part 110 and a lower end of the second derrick part 120. [ The stopper block 410 can be moved along the support rail 200 to move the second hydraulic cylinder 420 to the stopper block 410.

The stopper block 410 is moved by the second hydraulic cylinder 420 on the support rail portion 200 at a speed corresponding to the moving speed of the lower end of the first derrick part 110 and the lower end of the second derrick part 120 Can be moved. 3, a plurality of stopper blocks 410 may be provided for each of the rails 210 and 220. Accordingly, a plurality of second hydraulic cylinders 420 for moving the stopper block 410 may be installed .

On the other hand, when the drill derrick 100 changes from the second state to the first state, for example, an offshore structure or a drill ship with the drill derrick 100 is passed through the height- The driving part 300, that is, the first hydraulic cylinder, lifts the head part 130 of the drilling derrick part 100. In this case, Accordingly, the first derrick part 110 and the second derrick part 120 rotate about the upper end. 2, the first derrick part 110 rotates in a counterclockwise direction and the second derrick part 120 rotates in a clockwise direction.

As the first derrick part 110 and the second derrick part 120 rotate about their upper ends respectively, the lower end of the first derrick part 110 and the lower end of the second derrick part 120 are connected to the first rail 210 and the second rail 220 in the opposite direction and can be brought close to each other.

4 is a view showing a derrick structure according to another embodiment of the present invention.

[

In the present embodiment, the driving unit 2300 moves the lower part of the first derrick part 2110 of the drilling derrick 2100 to the lower side of the first derrick part 2110, And the second derrick part 2120 along the lateral direction. Thus, the head part 2130 of the drilling derrick 2100 can move up and down along the longitudinal direction, and as a result, the height of the drilling derrick 2100 can be adjusted.

Specifically, the third hydraulic cylinder 2310 and the fourth hydraulic cylinder 2320 are contracted to move the lower end of the first derrick part 2110 and the lower end of the second derrick part 2120 in opposite directions (directions away from each other) The first derrick part 2110 and the second derrick part 2120 rotate about their upper ends, respectively, so that the head part 2130 can be lowered. In this case, in FIG. 4, the first derrick part 2110 rotates clockwise and the second derrick part 2120 rotates counterclockwise.

The lower end of the first derrick part 2110 and the lower end of the second derrick part 2120 are moved in the directions opposite to each other (in a direction approaching each other) while the third hydraulic cylinder 2310 and the fourth hydraulic cylinder 2320 are extended, The first derrick part 2110 and the second derrick part 2120 rotate about their upper ends, respectively, so that the head part 2130 can be raised. 4, the first derrick part 2110 rotates counterclockwise and the second derrick part 2120 rotates clockwise.

The stopper part 2400 supports the head part 2130 so as to limit the lifting speed of the head part 2130 when the first derrick part 2110 and the second derrick part 2120 are moved by the driving part 2300 . That is, when the lower end of the first derrick part 2110 and the lower end of the second derrick part 2120 move along the support rail part 2200 by the operation of the driving part 2300, the stopper part 2400, It is possible to support the head portion 2130 so as to restrict the head portion 2130 from being abruptly raised or lowered.
