Abstract

The present invention relates to a device for storing a drilling pipe for drilling equipment and, more specifically, to a device for storing a drilling pipe for drilling equipment which is capable of buffering impact applied on the bottom part of a storage pipe using an elastic force of a spring, when inputting the drilling pipe inside the storage pipe, by joining a buffering unit equipped with the spring, on the lower side of the storage pipe where multiple drilling pipes are received while connected by a flange and forming a drain nozzle unit for discharging foreign materials such as mud on the lower side of the buffering unit; easily maintaining the spring and a plate inside the buffering unit by separately forming the buffering unit; and rapidly installing the drilling pipes by immediately utilizing the drilling pipes on an underwater working site, as the drilling pipes are kept inside a separate storage device while the drilling pipes are in a connected state.

Description

Storage device for drill pipe for drilling equipment

The present invention relates to a drilling pipe storage device for a drilling rig, and more particularly, to a drilling pipe storage device for a drilling rig, more specifically, to a drilling pipe storage device for a drilling rig, And a drain nozzle unit for discharging the same foreign substance to the outside. Thus, when the drilling pipe is put into the storage pipe, the shock applied to the bottom of the storage pipe can be buffered by the elastic force of the spring, It is possible to easily maintain the springs and plates in the cushion part and to store it in a separate storage device connected with the drilling pipe, Cost drilling pipe storage device.

Generally drilling rigs (drilling rigs) use drilling pipes to drill holes in the seabed.

These drilling pipes are temporarily loaded before they are installed and are connected to the drilling pipe just before installation.

However, conventionally, the drilling pipe is temporarily installed on the floor of the drilling equipment immediately before the drilling pipe is installed, or when the drilling pipe is dismantled after use, so that there is a problem that the drilling pipe can not be installed quickly when the drilling pipe is used continuously In addition, the foreign substances on the drilling pipe are contaminated at the bottom of the drilling equipment, and the working environment can not be kept clean.

In order to solve the above problems, according to the present invention, a cushioning portion having a spring is coupled to a lower side of a storage pipe in which a plurality of drilling pipes are connected in a flanged state, and a foreign matter such as clay is discharged to the outside The impact applied to the bottom of the storage pipe can be buffered by the elastic force of the spring when the drilling pipe is inserted into the storage pipe. By forming the buffer part in a detachable form, Provides a drilling pipe storage device for drilling pipes that can be installed easily and can be installed in a subsea site by storing the drilling pipe in a separate storage device in a connected state. .

According to an aspect of the present invention,

A storage pipe for storing a plurality of drilling pipes connected to each other in a flanged state is coupled to a lower side of the loading part and a buffer part for buffering an impact when the drilling pipe is inserted into the storage pipe is coupled to the lower side of the storage pipe.

According to the present invention, when the drilling pipe is inserted into the storage pipe, the shock applied to the bottom of the storage pipe can be buffered by the elastic force of the spring, and the buffer part can be separated so that the spring and the plate in the buffer part can be easily In addition, the drilling pipe can be stored in a separate storage device in a connected state, and the drilling pipe can be directly put into the subsea site, so that the drilling pipe installation work can be realized more quickly.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 shows a drilling pipe storage device of the present invention.
2 is a cross-sectional view showing a configuration of the essential part of the present invention.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, FIG. 1 and FIG.

According to the above drawings,

A storage pipe 2 in which a plurality of drilling pipes 20 are housed in a flanged state is coupled to a lower portion of the charging unit 1 and a shock is absorbed when the drilling pipe 20 is inserted into the storage pipe 2 And the buffer part (4) is coupled to the lower side of the storage pipe (2).

The buffering part (4)

And a buffer pipe (5) connected to the lower side of the storage pipe (2)

A hollow support part (11) is formed on the inner lower end of the buffer pipe (5)

A spring (10) is interposed on the upper portion of the receiving portion (11)

A top plate 7 for supporting the lower portion of the drilling pipe 20 is installed on the inner upper end of the damping pipe 5,

A shaft 8 is extended downward from the top plate 7 and a washer 9 engaged with the bottom of the receiving portion 11 is coupled to the end of the shaft 8 with a nut .

A first flange 3 is formed on the lower side of the storage pipe 2 and a second flange 6 is coupled to the upper end of the cushioning pipe 5 constituting the buffer part 4 so as to abut against the first flange 3, So that the buffer part 4 can be separated from the storage pipe 2.

And a drain nozzle part (12) for discharging foreign substances existing in the buffer pipe (5) to the outside is formed at the lower end of the buffer pipe (5).

The present invention relates to a drilling pipe storage device for temporarily storing a drilling pipe (20) before a drilling pipe (20) is installed under a deck below the sea, or vice versa when installing a drilling pipe (20) .

The drilling pipe storage device of the present invention is roughly divided into a charging section (1), a storage pipe (2), a buffer section (4), and a drain nozzle section (12).

The input unit 1 is an inlet through which the drilling pipe 20 is inserted.

A storage pipe 2 having a predetermined length is connected to the lower side of the charging unit 1 and a first flange 3 is formed at the lower end of the storage pipe 2.

Normally, the storage pipe 2 is used in a standing state, and three drilling pipes 20 connected by a flange are inserted and stored inside the storage pipe 2.

In the present invention, the buffer part (4) for buffering the shock applied when the drilling pipe (20) is inserted into the storage pipe (2) is coupled to the lower side of the storage pipe (2).

The buffering part 4 couples a separate buffering pipe 5 to the lower side of the storage pipe 2 and a second flange 6 is formed on the upper part of the buffering pipe 5, And the second flange 6 is connected as a bolt in a state in which they are in alignment with each other.

A hollow support portion 11 is formed at the middle portion of the buffer pipe 5 and a coil spring 10 is provided at an upper side of the support portion 11. [

The surface of the spring 10 is preferably coated with Teflon.

A top plate 7 for supporting the lower portion of the drilling pipe 20 is installed at the inner upper end of the damping pipe 5,

The shaft 8 is extended to the lower side of the top plate 7 so that the end of the shaft 8 passes through the center hole of the receiving portion 11 and the receiving portion 11 And the top plate 7 is supported by the elasticity of the spring 10. In this way,

When the top plate 7 is elastically supported by the spring 10 as described above, the impact applied to the top plate 7 when the drilling pipe 20 is inserted into the storage pipe 2 is transmitted to the spring 10, . &Lt; / RTI >

The shock absorber 4 can be separated from the storage pipe 2 as described above so that when an abnormality occurs in the spring 10 or the top plate 7 constituting the shock absorber 4, It will be possible to do.

On the other hand, a drain nozzle portion 12 is formed below the buffer pipe 5.

The drain nozzle unit 12 discharges the foreign substance to the outside when the foreign substance such as clay is accumulated in the buffer pipe 5 or when the liquid exists. The foreign matter is discharged to the drain nozzle unit 12 by connecting a separate hose to the drain nozzle unit 12 do.

The drilling pipe 20 used in the drilling equipment can be stored in a state of being connected to the storage device in advance and can be lifted from the storage device and moved to a position where the drilling pipe 20 can be installed Therefore, it is expected that the installation work of the drilling pipe becomes very easy.
