The derrick structure according to one aspect of the present invention comprises a lower derrick portion provided on a drill floor, an upper derrick portion which is provided on the lower derrick portion and whose transverse area is adjustable differently from the lower derrick portion, And an elevating portion for elevating the upper derrick portion with respect to the lower derrick portion.

Description

Derrick Structure {DERRICK STRUCTURE}

The present invention relates to a derrick structure.

The drill rig requires a Derrick structure for drilling. Derrick usually has the same shape as a high tower. Because these deriks are quite high, drill rigs can be a major obstacle to passing through places with air draft limitations.

For example, in order to pass through the Panama Canal or the Suez Canal, it is necessary to meet the Air Draft required by the Flight Administration, as it may pass under certain bridges during canal passage.

Therefore, if the height of the derrick included in the drill ship does not satisfy this requirement, the drill ship may not pass through the Panama Fort or the Suez Canal.

The lower derrick part 100 is a part provided on the drill floor 10 and constitutes the lower part of the derrick structure 1000 and an upper derrick part 200 to be described later is installed thereon. In this case, the lower derrick 100 may have a truss structure.

The upper derrick part 200 is provided on the lower derrick part 100 and can be adjusted in a transverse sectional area different from that of the lower derrick part 100. The upper derrick part 200 may have a truss structure like the lower derrick part 100. [

By adjusting the transverse sectional area of the upper derrick portion 200 differently from that of the lower derrick portion 100, even if the upper derrick portion 200 is raised or lowered relative to the lower derrick portion 100 as shown in FIGS. 4 and 6 The interference between the lower derrick portion 100 and the upper derrick portion 200 can be prevented.

1, 4 and 6 show a structure in which the upper derrick 200 is provided on the lower derrick 100. However, the present invention is not limited to this, 200 may be variously modified.

The elevating part 300 elevates the upper derrick part 200 with respect to the lower derrick part 100 with respect to the lower derrick part 100 and adjusts the height of the upper derrick part 200 It may be possible to adjust the height of the derrick structure 1000.

As described above, the derrick structure 1000 according to the present embodiment controls the transverse sectional area of the upper derrick 200 to be different from that of the lower derrick 100, The height of the derrick structure 1000 can be adjusted as needed.

4, the transverse sectional area of the upper derrick 200 may be adjusted to be smaller than the lower derrick 100 and the upper derrick 200 may be moved up and down relative to the lower derrick 100, .

6, it is also possible to adjust the transverse sectional area of the upper derrick 200 to be larger than the lower derrick 100 and to raise and lower the upper derrick 200 with respect to the lower derrick 100 .

Therefore, when passing through a specific bridge under the process of passing through the Panama Canal or the Suez Canal, the derrick structure (1000) is required to satisfy the air draft required by the Flight Administration Administration even if a portion of the derrick structure And the height of the substrate 1000 can be adjusted.

The upper derrick portion 200 may include a longitudinal frame 210, a transverse frame 220, a brace frame 230 and a telescoping joint 240. In the derrick structure 1000 according to the present embodiment,

1 to 7, the longitudinal frame 210 is a portion formed along the longitudinal direction, and the transverse frame 220 is formed along the lateral direction, The longitudinal frame 210 and the transverse frame 220 can form the main structural appearance of the upper derrick 200. [ In this case, the longitudinal frame 210 and the transverse frame 220 are made of a material having a predetermined rigidity such as a steel bar and / or a steel pipe, so that structural strength can be exerted.

The brace frame 230 is a portion interposed between the longitudinal frame 210 and the contact of the transverse frame 220 and can reinforce the rigidity of the longitudinal frame 210 and the transverse frame 220 with respect to the horizontal force. The brace frame 230 may be installed on the upper and side surfaces of the upper derrick 200 as shown in FIGS. 2 and 3. However, the brace frame 230 is not necessarily limited to this, And the like can be variously modified.

As shown in FIGS. 4 and 5, the transverse frame 220 is extended through the extensible joint 240 so that the entire length of the transverse frame 220 Can be reduced. 6 and 7, the entire length of the transverse frame 220 can be increased through the expansion joint 240. [

As described above, the derrick structure 1000 according to the present embodiment is configured such that the upper derrick portion 200 includes the longitudinal frame 210, the transverse frame 220, the brace frame 230, and the expansion joint 240, The cross-sectional area can be easily adjusted.

Here, the transverse frame 220 includes a plurality of frame separators 221 separated from each other, and the stretching joint 240 can connect the adjacent frame separators 221 to each other to adjust the interval between the frame separators .

5, since the frame separator 221 inserted into the expansion joint 240 has a relatively long length, the interval between the frame separators 221 connected to each other through the expansion joint 240 is narrow The overall length of the transverse frame 220 can be reduced.

7, since the length of the frame separator 221 inserted into the expansion joint 240 is relatively short, the interval between the frame separators 221 connected to each other through the expansion joint 240 is widened The overall length of the transverse frame 220 can be increased.

Meanwhile, the brace frame 230 may be partially bent to be adjustable to correspond to the length of the transverse frame 220 through the degree of folding of the bent portion.

5, when the entire length of the transverse frame 220 is reduced, the width of the brace frame 230 is relatively increased, and as a result, the width of the brace frame 230 is reduced in the space of the transverse frame 220 The frame 230 may be interposed.

7, when the entire length of the transverse frame 220 is increased, the degree of folding of the brace frame 230 is relatively small, and as a result, the length of the transverse frame 220 is increased, The frame 230 may be interposed.

Here, the brace frame 230 may be hinged to the outer circumference of the rotary plate 231, one end of which is coupled to the contact of the longitudinal frame 210 and the transverse frame 220, and the other end of which is rotatable about the central axis. Therefore, it is possible to adjust the cross-sectional area of the upper derrick 200 by adjusting the lengths of the brace frame 230 and the transverse frame 220 by only rotating the rotary plate 231.

5, when the rotary plate 231 is rotated counterclockwise as shown in FIG. 5, when the transverse area of the upper derrick 200 is reduced on the basis of the state shown in FIG. 2, The length of the transverse frame 220 can be reduced as the degree of folding increases.

In addition, when the transverse sectional area of the upper derrick 200 is increased on the basis of the state shown in FIG. 2, when the rotary plate 231 is rotated clockwise as shown in FIG. 7, The length of the transverse frame 220 can be increased.

In the derrick structure 1000 according to the present embodiment, the elevating portion 300 may include a lifting rail 310 and a lifting body 320.

8, the elevating rail 310 is installed along the longitudinal direction of the lower derrick 100, and the elevating rail 320 is moved along the elevating rail 310, (Not shown).

As a result, it is possible to minimize the distortion or deformation of the structure during the lifting and lowering of the upper derrick 200 relative to the lower derrick 100, so that the structural stability of the derrick 1000 can be secured while adjusting the height of the derrick 1000 .

Meanwhile, the lifting rail 310 and the lifting body 320 shown in FIG. 8 are merely examples for convenience of description, and are not limited thereto. The lifting rail 310 and the lifting body 320 may have various structures Lt; / RTI >

It will be apparent to those skilled in the art that various modifications and additions to, or additions to, the components may be made without departing from the scope of the present invention as set forth in the appended claims.
