Abstract

The present application relates to a locking system on a two-layer platform indicating beam using a bidirectional pipe column locker, belonging to the technical field of oil and gas drilling and production. The present application uses the bidirectional pipe column locker to stage-lock the pipe column during the pipe column pipe arrangement operation, reasonably reduces the interval distance between the pipe column and the bidirectional pipe column locker, thereby avoiding the large impact on the pipe column locker and the drilling equipment caused by the pipe column stand falling in windy weather, reducing the possibility of damage to the pipe column locker and the drilling equipment by the pipe column, and further reducing the risk of operation. Through the stage sealing and locking of the pipe column in the pipe column storage space by each bidirectional pipe column locker, more pipe columns can be accommodated in the effective length interval of the indicating beam. At the same time, each bidirectional pipe column locker can realize three-station work, so that one bidirectional pipe column locker can lock different pipe columns in the two adjacent pipe column storage spaces on its two sides, greatly improving the use efficiency of the bidirectional pipe column locker.

Description

TECHNICAL FIELD

[0001] The application relates to a locking system of a two-way pipe column locker on a two-layer platform finger beam and belongs to the technical field of oil and natural gas drilling and production. BACKGROUND

[0002] In the era when automatic technology is gradually applied to the oil drilling and production industry, for the drilling and workover operation field with poor working conditions, gradually reducing the operation risk of workers, reducing labor intensity, improving equipment operation efficiency and ensuring stable operation of equipment have become the main trend of development of the current drilling and workover equipment. With the application of mechanization and automation tools in the oil drilling and production industry, the oil drilling machine manufacturing technology in China has developed rapidly, and domestic oil drilling and production equipment manufacturers are actively conducting research and trial production of mechanized and automated pipe arrangement technology.

[0003] A one-way pipe column locker is usually used at the end of the finger beam on a conventional automatic two-layer platform. When the pipe column is not full between the finger beams during the operation process, strong wind or other bad weather often occurs, and the wind will blow down the pipe column and make it lean against the locking pin of the pipe column locker. During the leaning process, since the finger beam is long (close to 2 m), the pipe column will accelerate under the action of the wind, resulting in a large impact force of the pipe column on the locking pin of the pipe column locker, and accidents such as deformation or fracture of the locking pin of the pipe column locker are prone to occur. Figure 4 and Figure 5 As shown in the attached Figure 4 is a real photo of the locking pin of the end finger beam pipe column locker being deformed by the pipe column; and Figure 5 is a real photo of the locking pin of the end finger beam pipe column locker being fractured by the pipe column).

[0004] In order to solve the above problems, some manufacturers design and produce the full pipe column lockers of the power two-layer platform, that is, one pipe column locker is arranged on each pipe column, but this method still has defects, one is that the number of pipe column lockers is large, the installation and control are complex, and the cost is high; two is that due to the large size of the locking pin of the pipe column locker, too many pipe column lockers are installed on one finger beam, and the position is fixed, which can cause the reduction of the capacity of the two-layer platform, and the adjacent pipe columns of the stand box must be spaced, so that the pipe column arrangement of the stand box is complicated; three is that the full pipe column locker of the power two-layer platform can only be adapted to the drilling rig used in drilling, and usually the drilling rig uses only one to two pipe columns with small diameter difference, but the pipe column used in the offshore fixed platform drilling and workover rig has a diameter difference of about two times, and the number of pipe column arrangement required for workover is almost twice the number of drilling, so the full pipe column locker of the power two-layer platform is not suitable. Some manufacturers design and produce the power two-layer platform using spring sheets to block the pipe column from falling by friction, that is, a plurality of spring sheets are symmetrically arranged on each finger beam, and the movement of the pipe column is blocked by friction, but this method also has defects, one is that due to the fixed structure of the spring sheet, the normal pressure generated by the spring sheet will change with the change of the diameter of the pipe column, so when the pipe columns with different diameters are taken out and placed in the two-layer platform, the blocking force of the spring sheet on the pipe column will change greatly, when the diameter of the pipe column is small, the frictional resistance is small, and almost no effect; when the diameter of the pipe column increases by one specification, the movement of the manipulator will be blocked, and the movement of the manipulator is very unstable; two is that the use of spring sheets to block the pipe column will greatly increase the workload of the operator when the manipulator fails and the operator replaces the manipulator, and even the operator cannot operate; three is that due to the very bad weather of the ocean, the weather of more than ten levels of gale occurs very frequently, and the blocking force of the spring sheet on the pipe column is limited, and almost no effect on blocking the pipe column; therefore, the use of spring sheets to block the pipe column has obvious defects, and the spring sheets cannot replace the automatic pipe column locker. SUMMARY

[0005] The purpose of the present application is to provide a set of bidirectional pipe column lockers which can lock different diameters and quantities of pipe columns in two adjacent pipe column storage spaces, increase the number of pipe column arrangement of the two-layer platform, facilitate the arrangement of pipe columns in the stand box, improve the efficiency of the pipe column locker, and segmentally lock the pipe column during the pipe column arrangement operation; avoid the impact of the pipe column on the locking pin of the pipe column locker due to the falling of the pipe column in the gale, cause the deformation or fracture of the locking pin of the pipe column locker, damage the pipe column locker and the drilling equipment, and further reduce the operation risk.

[0008] The two-way pipe column locker comprises a locking bolt, a connecting screw, an end cover, a shell, a speed reducer, a sensor, an ear plate and a signal transmission interface, the speed reducer is installed on the end cover, and the gear at the end of the speed reducer is connected with the sensor, the locking bolt is L-shaped, one end of the locking bolt is connected with the output shaft of the speed reducer, the end cover is installed on the shell through the connecting screw, two groups of ear plates are welded on the lower part of the shell, and the two-way pipe column locker is installed on the finger beam through the bolt and the ear plate.

[0009] The shell tail of the two-way pipe column locker is provided with a signal transmission interface, the signal transmission interface is connected with the locker control system through the control cable, the locker control system is connected to the pipe column processing integrated control system through the control cable, the locker control system is controlled through the pipe column processing integrated control system, the signal acquisition and instruction transmission are realized through the locker control system, and the opening and closing of the locking bolt of the two-way pipe column locker are controlled.

[0010] The locking bolt of the intermediate two-way pipe column locker a, the intermediate two-way pipe column locker b and the inner two-way pipe column locker of the two-way pipe column locker has three working positions of left closing, middle opening and right closing.

[0011] The intermediate two-way pipe column locker a, the intermediate two-way pipe column locker b and the inner two-way pipe column locker are installed at 1-5 according to the length of the finger beam.

[0012] The first column pipe column storage space and the second column pipe column storage space share the same set of intermediate bidirectional pipe column lockers a, intermediate bidirectional pipe column lockers b and inner end bidirectional pipe column lockers; when locking different column pipe column storage spaces, the opening and closing direction of the locking pin will rotate 180° when locking the left and right two adjacent pipe column storage spaces; the third column pipe column storage space and the fourth column pipe column storage space and every two adjacent column pipe column storage spaces behind are similar to the first column pipe column storage space and the second column pipe column storage space, and the opening and closing direction of the locking pin will rotate 180° when locking the left and right two adjacent pipe column storage spaces.

[0013] The locker control system of the bidirectional pipe column locker is controlled by the pipe handling integrated control system, and the control object of the locker control system of the bidirectional pipe column locker and the state reached by the locking pin are determined by the pipe handling integrated control system according to the specific conditions such as the working pipe column diameter, the pipe rack state of the second floor and the pipe rack manipulator state.

[0014] The working process of the locking system of the bidirectional pipe column locker on the beam of the second floor includes the following steps: Figure 1 The front, rear, left and right directions described below are based on the

[0015] The first step is to open each bidirectional pipe column locker on the beam rack of the second floor body:

[0016] Before the pipe rack operation is performed, the locker control system sends an open door command to each bidirectional pipe column locker through a control cable, and the speed reducer starts to act, so that the locking pin of each bidirectional pipe column locker is in the open position, to ensure that the pipe column storage space between the beam racks is unobstructed; at the same time, the sensor returns the locking pin opening state signal to the locker control system through the control cable, to avoid the pipe column from colliding with the locking pin during the process of entering the pipe column storage space, and to ensure the safety of the operation;

[0017] The second step is to perform the pipe rack operation of the first column pipe column storage space by the pipe rack manipulator:

[0018] 2.1, when the pipe rack manipulator performs the pipe rack operation, the pipe column grabbed is started to be operated from the first column pipe column storage space on the right side of the beam rack of the second floor body, and then the pipe rack operation of each column pipe column storage space is sequentially performed after the first column pipe column storage space is fully filled with pipe columns;

[0019] 2.2, when the pipe rack manipulator performs the pipe rack operation of the first column pipe column storage space:

[0020] After the first pipe column is grabbed by the pipe string manipulator, the pipe string manipulator enters the pipe column storage space port of the first column on the right side of the finger beam row and moves to the tail end of the pipe column storage space. When the pipe column contacts the end face of the tail end of the pipe column storage space, the pipe column stops moving. At this time, the lock control system sends a lock pin closing signal to the inner end bidirectional pipe column lock on the finger beam row on the right side of the first column through the control cable. The lock pin is closed to lock the pipe column in the pipe column storage space in stages. After the inner end bidirectional pipe column lock completes the stage locking of the first pipe column, the pipe string manipulator is separated from the first pipe column and grabs the second pipe column for the next pipe string operation.

[0021] 2.3, After the second pipe column is grabbed by the pipe string manipulator, the pipe string manipulator continues to enter the pipe column storage space port of the first column on the right side of the finger beam row and moves to the inner end bidirectional pipe column lock at the tail end of the pipe column storage space. When the inner end bidirectional pipe column lock is close to being closed, the lock control system sends a lock pin opening signal to the inner end bidirectional pipe column lock through the control cable. The lock pin of the inner end bidirectional pipe column lock on the finger beam row is opened. After the second pipe column enters and is attached to the first pipe column, the lock control system sends a lock pin closing signal to the inner end bidirectional pipe column lock on the finger beam row through the control cable. The lock pin of the inner end bidirectional pipe column lock is closed again to lock the second pipe column in the pipe column storage space of the first column in stages. The cycle is repeated until the storage space in the inner end bidirectional pipe column lock of the first column of the pipe column storage space is fully filled with pipe columns.

[0022] 2.4, after the storage space in the inner end two-way pipe column lock of the first column of pipe column storage space is filled with pipes, the pipe arranging manipulator continues to grab pipes and enters from the port of the first column of pipe column storage space, when the pipe enters close to the inner end two-way pipe column lock, the locking pin of the inner end two-way pipe column lock opens and is in a normally open state, after the pipe continues to move and enters close to the pipe in the inner end two-way pipe column lock, the locking pin control system sends a locking pin closing signal to the middle two-way pipe column lock b on the finger beam row through the control cable, the locking pin of the middle two-way pipe column lock b closes, and the pipe in the middle two-way pipe column lock b of the pipe column storage space is locked in stages; when the pipe arranging manipulator continues to grab pipes and enters from the port of the first column of pipe column storage space, moves close to the middle two-way pipe column lock b, the locking pin control system sends a locking pin opening signal to the middle two-way pipe column lock b on the finger beam row through the control cable, the locking pin of the middle two-way pipe column lock b opens, after the pipe continues to move and enters the storage space of the middle two-way pipe column lock b and is close to the pipe, the locking pin control system sends a locking pin closing signal to the middle two-way pipe column lock b through the control cable, the locking pin closes again, and the pipe in the middle two-way pipe column lock b of the pipe column storage space is locked in stages; the cycle is repeated until the storage space in the middle two-way pipe column lock b of the first column of pipe column storage space is filled with pipes;

[0023] 2.5, after the storage space in the middle two-way pipe column lock b of the first column of pipe column storage space is filled with pipes, the pipe arranging manipulator continues to grab pipes and enters from the port of the first column of pipe column storage space, when the pipe enters close to the middle two-way pipe column lock b, the locking pin of the middle two-way pipe column lock b opens and is in a normally open state, after the pipe continues to move and enters close to the pipe in the middle two-way pipe column lock b, the locking pin control system sends a locking pin closing signal to the middle two-way pipe column lock a on the finger beam row through the control cable, the locking pin of the middle two-way pipe column lock a closes, and the pipe in the middle two-way pipe column lock a of the pipe column storage space is locked in stages; when the pipe arranging manipulator continues to grab pipes and enters from the port of the first column of pipe column storage space, moves close to the middle two-way pipe column lock a, the locking pin control system sends a locking pin opening signal to the middle two-way pipe column lock a on the finger beam row through the control cable, the locking pin of the middle two-way pipe column lock a opens, after the pipe continues to move and enters the storage space of the middle two-way pipe column lock a and is close to the pipe, the locking pin control system sends a locking pin closing signal to the middle two-way pipe column lock a through the control cable, the locking pin closes again, and the pipe in the middle two-way pipe column lock a of the pipe column storage space is locked in stages; the cycle is repeated until the storage space in the middle two-way pipe column lock a of the first column of pipe column storage space is filled with pipes;

[0024] 2.6, after the storage space in the middle two-way pipe column lock a of the first column of pipe column storage space is filled with pipes, the pipe arranging manipulator continues to grab the pipe column from the port of the first column of pipe column storage space, when the pipe column enters the middle two-way pipe column lock a, the locking bolt of the middle two-way pipe column lock a opens and is in the normal open state, after the pipe column continues to move and enters the pipe column in the middle two-way pipe column lock a, the lock control system sends a locking bolt closing signal to the outer end two-way pipe column lock on the outer end of the finger beam row through the control cable, the locking bolt of the outer end two-way pipe column lock closes, and the pipe column in the pipe column storage space is locked in stages; when the pipe arranging manipulator continues to grab the pipe column and moves to the port of the first column of pipe column storage space, the lock control system sends a locking bolt opening signal to the outer end two-way pipe column lock on the outer end of the finger beam row through the control cable, the locking bolt of the outer end two-way pipe column lock opens, after the pipe column continues to move and enters the pipe column in the pipe column storage space, the lock control system sends a locking bolt closing signal to the outer end two-way pipe column lock through the control cable, and the locking bolt closes again to lock the pipe column in the pipe column storage space; the above steps are repeated until the pipe column storage space in the first column of pipe column storage space is filled with pipes, and the pipe column in the first column of pipe column storage space of the finger beam row is arranged.

[0025] Step 3, the pipe arranging manipulator performs pipe arranging operation of other columns of pipe column storage spaces

[0026] When the pipe column in the first column of pipe column storage space is arranged, the lock control system sends a closing signal to the outer end two-way pipe column lock at the end of the finger beam row through the control cable, the locking bolt of the outer end two-way pipe column lock closes, so that all the pipe columns in the first column of pipe column storage space are sealed and locked; the pipe arranging manipulator continues to grab the pipe column to perform pipe arranging operation of the second column, the third column and other columns, and the pipe arranging operation of other columns is repeated according to the steps of step 2, and so on, until the whole pipe arranging operation of the two-layer table body is completed.

[0027] The beneficial effects of the application are as follows:

[0028] The application can reasonably reduce the interval distance between the pipe column and the bidirectional pipe column locker by locking the pipe column in stages during the pipe column pipe rack operation, thereby avoiding the impact of the pipe column stander falling in windy weather on the pipe column locker and the drilling equipment, reducing the possibility of the pipe column damaging the pipe column locker and the drilling equipment, and further reducing the risk of operation. The bidirectional pipe column locker can form a sealing lock for the pipe column in the pipe column storage space, and can fully utilize the effective length of the finger beam row interval to accommodate more pipe columns. Meanwhile, the bidirectional pipe column locker can work in left closing, middle opening and right closing three stations, so that one bidirectional pipe column locker can lock different pipe columns in two adjacent pipe column storage spaces on both sides of the bidirectional pipe column locker, greatly improving the use efficiency of the bidirectional pipe column locker.

DETAILED DESCRIPTION

[0037] (see the attached Figures 1-3The locking system of the two-way pipe column lock on the two-layer platform finger beam comprises a two-layer platform body 1, a finger beam row 2, a two-way pipe column lock 3, a mounting bolt 4, a control cable 5, a lock control system 6 and a pipe column processing integrated control system 15. The plurality of finger beam rows 2 are installed in parallel on the two-layer platform body 1 to form an integral pipe column storage space 16. The two-way pipe column lock 3 comprises an outer two-way pipe column lock 3-1, a middle two-way pipe column lock a 3-2, a middle two-way pipe column lock b 3-3 and an inner two-way pipe column lock 3-4. The locking pin 7 of the middle two-way pipe column lock a 3-2, the middle two-way pipe column lock b 3-3 and the inner two-way pipe column lock 3-4 for controlling the two-way pipe column lock 3 has three working positions of left closed, middle open and right closed. The middle two-way pipe column lock a 3-2, the middle two-way pipe column lock b 3-3 and the inner two-way pipe column lock 3-4 can be installed at 1-5, but at least one inner two-way pipe column lock 3-4 must be installed.

[0038] The two-way pipe column lock 3 comprises a locking pin 7, a connecting screw 8, an end cover 9, a shell 10, a speed reducer motor 11, a sensor 12, an ear plate 13 and a signal transmission interface 14. The speed reducer motor 11 is installed on the end cover 9, and the gear at the end of the speed reducer motor 11 is connected with the sensor 12. The locking pin 7 is L-shaped, and one end of the locking pin 7 is connected with the output shaft of the speed reducer motor 11. The end cover 9 is installed on the shell 10 through the connecting screw 8, and two groups of ear plates 13 are welded on the lower part of the shell 10. The two-way pipe column lock 3 is installed on the finger beam row 2 through the bolt and the ear plate 13. The tail part of the shell of the two-way pipe column lock 3 is provided with the signal transmission interface 14, the signal transmission interface 14 is connected with the lock control system 6 through the control cable 5, the lock control system 6 is connected with the pipe column processing integrated control system 15 through the control cable 5, the signal acquisition and instruction transmission are realized through the pipe column processing integrated control system 15, and the opening and closing of the locking pin 7 of the two-way pipe column lock 3 are controlled.

[0039] The outer end two-way pipe column lock 3-1 is installed on the outer end head of each finger beam row 2 through the mounting bolt 4. The middle two-way pipe column lock a 3-2, the middle two-way pipe column lock b 3-3 and the inner two-way pipe column lock 3-4 are uniformly installed on each finger beam row 2 from the outside to the inside through the mounting bolt 4, so that the pipe column storage space 16 between each finger beam row 2 is divided into a plurality of independent locking spaces, each independent locking space can accommodate 2-3 large-diameter pipe columns or 4-6 small-diameter pipe columns, and the middle two-way pipe column lock a 3-2, the middle two-way pipe column lock b 3-3 and the inner two-way pipe column lock 3-4 are arranged in the form of interval at an interval of one row of finger beam rows 2.

[0040] The lock control system 6 of the bidirectional pipe column lock 3 is controlled by the pipe column processing integrated control system 15, and the pipe column processing integrated control system 15 determines the control object of the lock control system 6 of the bidirectional pipe column lock 3 and the state reached by the lock pin 7 according to the specific conditions such as the working pipe column diameter, the pipe arrangement state of the second floor beam and the pipe arrangement manipulator state.

[0041] The locking system of the bidirectional pipe column lock on the second floor beam includes the following steps: taking each stage storage space of the pipe column storage space 16 as an example, the front, rear, left and right directions are taken as the basis Figure 1 ;

[0042] The first step is to open each bidirectional pipe column lock 3 on the beam arrangement 2 of the second floor body 1

[0043] Before the pipe arrangement operation is performed, the lock control system 6 sends an open door command to each bidirectional pipe column lock 3 through the control cable 5, and the speed reducer 11 starts to act, so that the lock pin 7 of each bidirectional pipe column lock 3 is in the open position, so as to ensure that the pipe column storage space 16 between the beam arrangements 2 is unobstructed; at the same time, the sensor 12 returns the lock pin 7 open state signal to the lock control system 6 through the control cable 5, so as to avoid the pipe column from colliding with the lock pin 7 during the process of entering the pipe column storage space 16, and to ensure the safety of the operation; in addition, during the pipe arrangement operation, since the pipe column is inclined outward by about 0.5 m for arrangement, under the condition that the external force is lost and there is no strong wind, the pipe column generally will not fall on the lock pin of the pipe column lock.

[0044] The second step is that the pipe arrangement manipulator performs the pipe arrangement operation of the first column pipe column storage space 16:

[0045] 2.1, when the pipe arrangement manipulator performs the pipe arrangement operation, the pipe column grabbed by the pipe arrangement manipulator is arranged from the first column pipe column storage space 16 on the right side of the beam arrangement 2 of the second floor body 1, and then the pipe arrangement operation of each column pipe column storage space 16 is sequentially performed after the first column pipe column storage space 16 is fully arranged with pipe columns;

[0046] 2.2, the pipe arrangement manipulator performs the pipe arrangement operation of the first column pipe column storage space 16:

[0047] After the pipe manipulator grasps the first pipe column, it enters the port of the pipe column storage space 16 of the first column on the right side of the finger beam row 2 and moves to the tail end of the pipe column storage space 16. When the pipe column contacts the end face of the tail end of the pipe column storage space 16, the pipe column no longer moves. At this time, the control system sends a closing signal of the locking bolt 7 to the inner bidirectional pipe column lock 3-4 on the finger beam row 2 of the first column on the right side through the control cable 5, and the locking bolt 7 is closed to lock the pipe column in the pipe column storage space 16 periodically; after the inner bidirectional pipe column lock 3-4 completes the periodic locking of the first pipe column, the pipe manipulator is separated from the first pipe column and grasps the second pipe column for the next pipe arrangement operation;

[0048] 2.3, After the pipe manipulator grasps the second pipe column, it continues to enter the port of the pipe column storage space 16 of the first column on the right side of the finger beam row 2 and moves to the inner bidirectional pipe column lock 3-4 at the tail end of the pipe column storage space 16. When the inner bidirectional pipe column lock 3-4 is close to being closed, the lock control system 6 sends an opening signal of the locking bolt 7 to the inner bidirectional pipe column lock 3-4 through the control cable 5, and the locking bolt 7 of the inner bidirectional pipe column lock 3-4 on the finger beam row 2 is opened. After the second pipe column enters and is attached to the first pipe column, the lock control system 6 sends a closing signal of the locking bolt 7 to the inner bidirectional pipe column lock 3-4 on the finger beam row 2 again through the control cable 5, and the locking bolt 7 of the inner bidirectional pipe column lock 3-4 is closed again to lock the second pipe column in the pipe column storage space 16 of the first column periodically; the cycle is repeated until the storage space in the inner bidirectional pipe column lock 3-4 of the first column of the pipe column storage space 16 is filled with four pipe columns;

[0049] 2.4, after the storage space in the inner end two-way pipe column lock 3-4 of the first column pipe column storage space 16 is filled with 4 pipe columns, the pipe arranging manipulator continues to grab pipe columns from the port of the first column pipe column storage space 16, when the pipe column approaches the inner end two-way pipe column lock 3-4, the locking bolt 7 of the inner end two-way pipe column lock 3-4 opens and is in a normally open state, after the pipe column continues to move and fits in the pipe column in the inner end two-way pipe column lock 3-4, the lock control system 6 sends a locking bolt 7 closing signal to the middle two-way pipe column lock b3-3 on the finger beam row 2 through the control cable 5, the locking bolt 7 of the middle two-way pipe column lock b3-3 closes, and the pipe column in the middle two-way pipe column lock b3-3 of the pipe column storage space 16 is locked in stages; when the pipe arranging manipulator continues to grab pipe columns from the port of the first column pipe column storage space 16 and moves to approach the middle two-way pipe column lock b3-3, the lock control system 6 sends a locking bolt 7 opening signal to the middle two-way pipe column lock b3-3 on the finger beam row 2 through the control cable 5, the locking bolt 7 of the middle two-way pipe column lock b3-3 opens, after the pipe column continues to move and fits in the storage space of the middle two-way pipe column lock b3-3, the lock control system 6 sends a locking bolt 7 closing signal to the middle two-way pipe column lock b3-3 through the control cable 5, the locking bolt 7 closes again, and the pipe column in the middle two-way pipe column lock b3-3 of the pipe column storage space 16 is locked in stages; the cycle is repeated until the storage space in the middle two-way pipe column lock b3-3 of the first column pipe column storage space 16 is filled with 4 pipe columns;

[0050] 2.5, after the storage space in the middle bidirectional column lock b3-3 of the first column of column storage spaces 16 is filled with 4 columns, the column stacking manipulator continues to grab columns from the port of the first column of column storage spaces 16, when the column approaches the middle bidirectional column lock b3-3, the locking pin 7 of the middle bidirectional column lock b3-3 opens and is in a normally open state, after the column continues to move and fits in the column in the middle bidirectional column lock b3-3, the lock control system 6 sends a locking pin 7 closing signal to the middle bidirectional column lock a3-2 on the finger beam row 2 through the control cable 5, the locking pin 7 of the middle bidirectional column lock a3-2 closes, and the column in the middle bidirectional column lock a3-2 of the column storage space 16 is locked in stages; when the column stacking manipulator continues to grab columns from the port of the first column of column storage spaces 16 and moves to approach the middle bidirectional column lock a3-2, the lock control system 6 sends a locking pin 7 opening signal to the middle bidirectional column lock a3-2 on the finger beam row 2 through the control cable 5, the locking pin 7 of the middle bidirectional column lock a3-2 opens, after the column continues to move and fits in the storage space of the middle bidirectional column lock a3-2, the control system 6 sends a locking pin 7 closing signal to the middle bidirectional column lock a3-2 through the control cable 5, the locking pin 7 closes again, and the column in the middle bidirectional column lock a3-2 of the column storage space 16 is locked in stages; this cycle continues until the storage space in the middle bidirectional column lock a3-2 of the first column of column storage spaces 16 is filled with 4 columns;

[0051] 2.6 After four tubing columns are filled in the storage space of the intermediate bidirectional tubing locker a3-2 in the first column's tubing storage space 16, the tubing manipulator continues to grab tubing columns and enter through the port of the first column's tubing storage space 16. When the tubing column approaches the intermediate bidirectional tubing locker a3-2, the locking bolt 7 of the intermediate bidirectional tubing locker a3-2 opens and remains in the normally open state. After the tubing column continues to move and comes into contact with the tubing column in the intermediate bidirectional tubing locker a3-2, the locker control system 6 sends a locking bolt 7 closing signal to the outer bidirectional tubing locker 3-1 located at the outer end of the finger beam row 2 via the control cable 5. The locking bolt 7 of the outer bidirectional tubing locker 3-1 closes, performing phased locking of the tubing columns in the tubing storage space 16; when the tubing manipulator... As the pipe column continues to be moved to the port of the first column storage space 16, the locking device control system 6 sends an open signal for the locking bolt 7 to the outer bidirectional pipe column locking device 3-1 located at the outer end of the finger beam row 2 via the control cable 5. The locking bolt 7 of the outer bidirectional pipe column locking device 3-1 is opened. After the pipe column continues to move into the pipe column storage space 16 and fits against the pipe column in the storage space, the locking device control system 6 sends a close signal for the locking bolt 7 to the outer bidirectional pipe column locking device 3-1 via the control cable 5. The locking bolt 7 closes again, locking the pipe column in the pipe column storage space 16. This cycle continues until the storage space in the first column of pipe column storage space 16 is filled with 16 pipe columns. At this point, the pipe column arrangement in the first column of pipe column storage space 16 of the finger beam row 2 is completed.

[0052] The third step involves the tubing robot performing tubing arrangement operations in the storage spaces of the other tubing columns.

[0053] After the pipes in the first column storage space 16 are laid out, the locking control system 6 sends a closing signal to the outer bidirectional pipe locker 3-1 at the end of the finger beam 2 via the control cable 5. The locking bolt 7 of the outer bidirectional pipe locker 3-1 closes, thereby sealing and locking the 16 pipes in the first column storage space 16. The pipe laying robot continues to grab pipes to carry out the pipe laying operations for the second column, the third column, and other columns. The pipe laying operations for other columns can be repeated in sequence according to the steps in the second step, and so on, until all pipe laying operations of the second platform body 1 are completed.

[0054] The outer bidirectional tubular locking device 3-1, the middle bidirectional tubular locking device a3-2, the middle bidirectional tubular locking device b3-3 and the inner bidirectional tubular locking device 3-4 are arranged at intervals on the finger beam row 2. The locking device control system 6 of the bidirectional tubular locking device 3 is an automatic control system.

[0055] The lock control system 6 of the bidirectional pipe column lock 3 is controlled by the pipe column processing integrated control system 15, and the pipe column processing integrated control system 15 determines the control object of the lock control system 6 of the bidirectional pipe column lock 3 and the state reached by the lock pin 7 according to the specific conditions such as the working pipe column diameter, the pipe arrangement state of the second floor and the pipe arrangement manipulator state.

[0056] The arrangement mode and locking of the bidirectional pipe column lock 3 of the other side pointing beam arrangement 2 of the second floor are completely similar to the above method, but the rotation direction sequence of the lock pin 7 of the bidirectional pipe column lock 3 is changed to adapt to the needs of the pipe arrangement.

Any simple modification or deformation of the above specific embodiment according to the technical essence of the present application by the ordinary skilled in the art after reading the present application, and the equivalent embodiments changed or modified by using the disclosed technical content are still within the scope of the technical scheme of the present application, and do not deviate from the essence and scope of the present application.
