The present invention relates to an apparatus for transporting a pipe for oil and gas drilling in the sea bed, and more particularly to an apparatus using a gripper for gripping a pipe as a tongue as a tongue.

The amount of resources to be harvested has been increasing due to industrialization and industrial development for a long time, and the dependence of energy resources on the seabed is increasing. As the mining and reliance on the seabed energy resources is increased, drilling workload of drill ship is increasing.

In the case of Korea, exploration is continued in some areas where development is possible since the 1970s. In the western and southern seas of Korea, the continental shelf is developed and oil is likely to be buried. In particular, US oil companies drilling in the south of Jeju Island estimate that at least 600 million barrels of oil will be buried. In addition, private companies in Korea are engaged in oil and natural gas development projects in the sea of Madura in Indonesia and the sea in North Bay.

Drill rigs use a variety of methods to transfer tubular members from a pipe rack adjacent to the bottom of the drill to a small hole or borehole on the bottom of the drill to connect it to a previously transported pipe or tubular string. The term " tubular "or" pipe ", as used herein, refers to any shape of drilling pipe, drill collar, casing, liner, bottom hole assembly: BHA) and other types of tubes known in the art.

Typically, drilling rigs utilize a combination of a drilling crane and a transfer system to transport the pipe from the pipe rack to a vertical position above the wellhead center. A distinct disadvantage of the prior art systems is that it involves significant manual labor in attaching the pipe elevator to the pipe and moving the pipe from the drill rack to the well head rotary table do. These manual movements near the workers are potentially very dangerous and in fact have caused many injuries in drilling. This risk can also be linked to pipe damage, which may affect the integrity of the connection between successive pipe lines in the well.

[0002] A pipe transporting apparatus for transporting a pipe to a low-lying state comprises a supporting structure, a support structure extending from the support structure, An arm capable of moving between a spaced first position and a second position on the lower surface and a stiffening means cooperating with the arm when the arm and the support structure are in the second position To a pipe conveying device for conveying a pipe to a bottom of a slope. The stiffening means applies a mechanical resistance to the arm in the second position. In the 10 < th > -0113607, the second position is the end of the support structure and the progression of the arm. The strengthening means cooperates with one end of the arm on the opposite side of the support structure. The energizing means applies a variable resistance to the arm when the arm moves from the first position to the second position. The variable resistor becomes larger when the arm is in the second position. Gripper means is attached to one end of the arm on the opposite side of the support structure. The gripper means houses a pipe therein. The gripper means supports the pipe in a vertical direction when the support structure and the arm are in the second position. In addition, the gripping means grips the horizontal pipe when the arm and the support structure are in the first position. The support structure has an open interior area. The gripper means is coupled to the arm such that the pipe moves through the open interior region as the support structure and the arm move from the first position to the second position.

The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and similar parts are denoted by like reference characters throughout the specification.

Throughout the specification, when a part is referred to as being "connected" (connected, connected, coupled) with another part, it is not only the case where it is "directly connected" "Is included. Also, when an element is referred to as "comprising ", it means that it can include other elements, not excluding other elements unless specifically stated otherwise.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The singular expressions include plural expressions unless the context clearly dictates otherwise. In this specification, the terms "comprises" or "having" and the like refer to the presence of stated features, integers, steps, operations, elements, components, or combinations thereof, But do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, or combinations thereof.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention relates to a pipeline for marine drilling that is attached to a crane, comprising: a main beam 100 in a longitudinal direction of a pipe to be transported; a crane connection part 200 installed in the center of the main beam 100; And a pipe grasping part 300 installed at the bottom of the main beam 100. The grasping part 300 includes four or more gripper fingers 310 for grasping a pipe, The pipe supporting part 110 is provided at both ends of the pipe supporting part 110 and the pipe supporting part 110. The pipe supporting part 110 adjusts the position and the supporting force of the pipe contacting part 111 and the pipe contacting part 111, And the arm 112 for connecting the pipe contact hole 111 and the cylinder 112 to each other by using the gripper fingers. The pipe conveying device can be fastened to the crane head of the crane through the crane fastener 250. The crane fastener 250 may be physically coupled to the crane head, and may also provide electrical connection for connection of a control device, a sensor, etc., which will be described later.

As shown in FIGS. 1 and 3, the gripper fingers 310 have a curved portion on the inside in order to grasp the pipe, and a pair of gripper fingers 310 grip the pipe. If only one set of gripper fingers is used to grip the pipe, it is not easy to balance the pipe. Therefore, it is desirable to install four or more gripper fingers and operate the unit more than two sets. The movement of the gripper fingers 310 can be interlocked so as to move at the same time, and different driving means may be provided for each group in order to move a pipe which is thick or thin, if necessary. The gripper finger 310 is preferably driven by a hydraulic cylinder, but a driving device such as a motor may be used. The present invention does not limit the driving source of the gripper finger 310. [ According to the configuration of the gripper fingers 310, it is suitable to grip the pipe of 5.5 to 30 inches, and it is possible to grip the pipe of 12 tons of load.

3, the gripper fingers 312 and the rear gripper fingers 311 are not symmetrical with respect to the main beam 100. The gripper fingers 312 are disposed on one side of the gripper fingers 312, And the gripper fingers 311 on the other side are driven by the cylinders. Such a configuration makes it possible to secure higher durability by reducing the moving member and increasing the fixed installation structure, and it is possible to grasp the pipe having a higher weight in a more stable manner. However, it is also possible that all of the gripper fingers 310 can be driven as needed, and the gripper fingers 310 in each set can be configured symmetrically with respect to the main beam 100. [ The latter configuration may have the advantage of enhancing the flexibility of gripping in gripping a pipe of varying pipe thickness, but as described above, there may be some damage in terms of durability and grip stability.

In addition, as described above, the present invention provides a pipe support 110 for supporting a pipe at both ends of the main beam 100, and the pipe support 110 includes a pipe contact 111 A cylinder 112 for adjusting the position and the supporting force of the pipe contactor 111 and an arm 113 for connecting the pipe contactor 111 and the cylinder 112 are provided. This provides a configuration in which the pipe contact portion 111 pushes the upper surface of the gripped pipe so that the pipe gripped by the pipe grip portion 300 stably grips without stably swinging. This is because the curvature of the inner surface of the gripper fingers 310 can not always be adjusted to the gripped pipe. If the length of the pipe is long, the effect of expanding the gripping length can be expected. Further, when the pipe shakes if necessary, the pressure can be controlled in real time in reverse phase to the vibration of the pipe in accordance with the pipe shake, thereby suppressing the shaking of the pipe. Such shake suppression can be achieved by controlling the hydraulic pressure of the cylinder 112 in real time by the control device processing information from the gyro sensor or the like.

The main beam 100 is coupled to the crane connecting part 200 so as to rotate about a connecting shaft 210 and is disposed at one end of the main beam 100 to adjust the inclination of the main beam 100 A tilting cylinder 120 is installed at one end of the tilting cylinder 120 and a tilting cylinder 120 is connected to a tilting cylinder 120 at one end of the tilting cylinder 120. The other end of the tilting cylinder 120 is connected to the crane connecting part 200, And adjust the pressure of the cylinder so as to adjust the inclination of the main beam 100.

Even when the pipe gripping portion 300 of the pipe conveying device of the present invention grasps the center of the pipe, when the pipe to be gripped is long and heavy, the pipe tilts due to the action of an external force such as wind, And rotation and the like are inevitable. The longer and heavier the pipe, the greater the risk of work and the lower the efficiency of the work. The tilt cylinder 120 supports the eccentric load on the tilting of the pipe, thereby distributing the load and balancing the pipe.

In another embodiment of the present invention, the main beam 100 is rotated about the connecting shaft 210 so that the main beam 100 is perpendicular to the crane connecting portion 200, that is, And horizontally moves in the longitudinal direction of the beam 100. [ In such a configuration, the tilting cylinder 120 horizontally moves the main beam 100 in the longitudinal direction with respect to the crane connecting portion 200, and the tilting cylinder 120 is moved such that the tilting cylinder 300 accurately grasps the center of the pipe I will. By gripping the center of the pipe precisely, it is possible to prevent the pipe from tilting. In addition, when the pipe is wobbled if necessary, the gripping position of the pipe gripping part 300 is shifted in real time against the inclination of the pipe, whereby the fluctuation of the pipe can be suppressed. The real-time movement of the pipe gripper 300 can be performed by real-time processing of information from the gyro sensor or the like by the control device and controlling the cylinder hydraulic pressure in real time.

The crane connecting part 200 is composed of an upper member 220 and a lower member 230. The crane connecting part 200 includes a rotating joint 240 at a coupling part of the upper member 220 and the lower member 230, The lower member 240 preferably includes a rotation reducing device 241 for preventing the upper member 220 from rotating at a speed higher than that of the lower member 230. When a long pipe is rotated, the movement distance of the pipe end can reach several meters with only a few degrees of movement, which increases the risk of operation. Accordingly, it is preferable to control the rotation speed. Accordingly, it is preferable that the rotation speed reduction device 241 controls the rotation speed of the pipe to 0 to 0.5 rpm.

In addition, the present invention is further characterized in that the cylinder 112, the tilt cylinder 120 and the rotary speed reducer 241 are controlled by a single control device, and the control device includes a sensor The deceleration ratio between the cylinder 112 and the tilt cylinder 120 and the rotation speed reduction device 241 based on information from the rotation speed reduction device 241. [ As described above, the pipe can be subjected to various movements such as horizontal rotation, vibration, tilting in the vertical direction, and the like due to external forces such as wind and an inertial force when moving. The movement of these pipes not only increases the risk of operation but also reduces the efficiency of the work. It is not easy for the user to directly control the cylinders and the rotary speed reducing device to suppress such movement. Accordingly, the present invention relates to a method of controlling the number of rotations of a cylinder (e.g., a cylinder) in a direction of suppressing the motion by using a sensor to numerically quantify various motions such as horizontal rotation, vibration, tilting in a vertical direction, 112 and the tilt cylinder 120 and the rotation speed reduction device 241 in real time.

And a display device for displaying the hydraulic pressure distribution status and the rotation deceleration status according to the control device so that the user can confirm the status. Such a control interface refers to an exemplary view of the interface of Fig. That is, the present invention provides a horizontal catwalk moving technique for mounting an encoder for a sensor signal and moving the pipe to a desired position while keeping the direction of the device constant while rotating. As shown in FIG. 5, it can be easily operated by a push button of the control screen through the interface. According to the control interface, the rotational speed is controlled to 0 to 0.5 rpm, and the inclination of the main beam 100 is controlled to be 7.5 degrees.

The upper member 220 of the crane connecting part 200 has a length adjusting cylinder 221 for adjusting the length of the upper member 220 and the upper first member 222 of the upper member And the upper second member 223 into which the upper first member 222 is inserted to adjust the length of the upper member 220. This can assist in starting the height control of the crane, and if the pipe needs to be lowered below the height at which the crane can be lowered, it can compensate for the shortage.

It will be understood by those skilled in the art that the foregoing description of the present invention is for illustrative purposes only and that those of ordinary skill in the art can readily understand that various changes and modifications may be made without departing from the spirit or essential characteristics of the present invention. will be. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive. For example, each component described as a single entity may be distributed and implemented, and components described as being distributed may also be implemented in a combined form.
