The groove body 22 is a fan-shaped structure as a whole, including an inner ring fixedly connected to the outer periphery of the cylinder 14 and a plurality of radial partitions fixedly connected to the inner ring along the circumferential direction.

[0038] An outer ring guard plate 23 is commonly sleeved on the outer periphery of the two pipe trough assemblies 6. The outer ring guard plate 23 is composed of a plurality of guard plates. Each guard plate corresponds to the position between two adjacent partitions. Every two guard plates are fixedly connected with bolts. The outer ring guard plate 23 is integrally fixedly connected to the drilling rig hoisting frame.

The main structure of the ejection mechanism assembly 8 includes an adjustment pad 26, a spring a27, a push body 28, a nut 29, a telescopic guide rod 30, and a spring sleeve 31.

The inner ring of the spring sleeve 31 is sequentially equipped with a spring a27 and a telescopic guide rod 30. The end of the telescopic guide rod 30 passes through the push body 28. The outer push surface of the push body 28 is an arc surface and is connected with an adjustment pad 26 and a nut 29. When the outer layer pipe column 4 is removed, the compressed spring a27 bounces the inner layer pipe column 4 to the outer layer designated pipe removal position through the push body 28. In addition, the adjustment pad 26 is located between the push body 28 and the nut 29 on the telescopic guide rod 30. By increasing or decreasing the thickness of the adjustment pad 26, the spring force value can be adjusted, and then the initial placement position of the pipe column 4 can be adjusted. The spring a27 can be a single spring or a combined spring of inner and outer rings. The number of the ejection mechanism assembly 8 can be two or one. The finger spring plate 24 of the straightening mechanism assembly 7 and the ejection mechanism assembly 8 cooperate to limit the radial position of the inner and outer ring pipe strings 4, and then each pipe string 4 can be sent to the designated pipe grabbing position through the circumferential rotation of the driving motor.

[0041] like Fig.12 As shown, the main structure of the mechanical positioning assembly 9 includes a seat plate 32, a limit plate 33, a spring b34, and an end cover 35. The limit plate 33 is fixedly connected to the drilling table at the designated pipe taking position to limit the pipe slot assembly 6, and the end cover 35 is fixedly connected to the bottom of the pipe slot assembly 6 at a position corresponding to the pipe column 4, as shown in FIG. Fig.13 As shown, the bottom of the seat plate 32 is fixed with a plurality of pins, which pass through the end cover 35. The pins are pierced with springs b34. The springs b34 are located between the seat plate 32 and the end cover 35, and the two ends are respectively in contact with the springs b34 and the end cover 35. When the pipe column 4 is not removed, the seat plate 32 is pressed down, and the pins at the bottom of the seat plate 32 are blocked by the limit plate 33 to achieve mechanical limit. When the pipe column 4 is removed, the seat plate 32 is bounced up by the spring b34, and no mechanical limit is performed, and the pipe arrangement device can continue to rotate. In addition, the mechanical positioning assembly 9 can be used in conjunction with the electronic limit. The end of the top drive motor 11 or the bottom drive motor 21 is equipped with an encoder, which can accurately identify the circumferential position of the pipe column 4. When the pipe column 4 rotates a specified angle, the encoder sends a signal to the drilling rig electronic control system, and the electronic control system realizes electronic limit by controlling the pneumatic and stop of the drive motor. The pipe arrangement device preferably adopts electronic limit. When it fails, the mechanical positioning assembly 9 performs limit.

[0042] The main function of the present invention is to rotate the pipe string 4 in the pipe arrangement device through the driving mechanism, the mechanical positioning assembly 9 cooperates with the electronic limiter to realize the double locking of the circumferential rotation position, the ejection mechanism assembly 8 and the straightening mechanism assembly 7 realize the radial position locking of the pipe string 4, and then cooperate with the pipe grabbing device 3 to transfer the pipe string 4 to the designated pipe taking position and the wellhead center. The present invention is convenient to hoist and move, has a simple structure and is light in weight. It can realize the automatic processing of the pipe string in conjunction with the pipe taking device, and is suitable for working conditions such as the seabed and swamps, and can also be used for compact drilling rigs with limited sites.

[0043] The working principle of the cylindrical pipe arrangement device of the present invention is: a cylindrical structure is adopted, and the number of cylindrical pipe arrangement devices is selected according to the on-site conditions. The pipe column 4 can be arranged in two layers, inner and outer, or in multiple layers. The driving mechanism drives the cylinder 14 or the outer cylinder 18 to rotate, and then drives the pipe column 4 on the pipe slot assembly 6 to rotate. The two pipe slot assemblies 6 are respectively installed on the top and bottom of the cylinder 14 or the outer cylinder 18, wherein the partitions of the slot 22 and the outer ring guard plate 23 limit the circumferential position of the pipe column 4 and prevent the pipe arrangement device from radially escaping during horizontal transportation. The two straightening mechanism assemblies 7 are axially arranged on the inner side of the two pipe slot assemblies 6, and each two finger spring plates 24 cooperate to limit the maximum radial position of the pipe column 4. The two ejection mechanism assemblies 8 are axially arranged on the inner side of the two straightening mechanism assemblies 7. After the outer layer pipe column 4 is taken away, the inner layer pipe column 4 is ejected to the outer layer specified maximum radial position. The mechanical positioning assembly 9 is arranged at the bottom of the pipe groove assembly 6. When the pipe arrangement device rotates to the designated pipe removal position, it identifies whether the pipe column 4 has been removed. If it has been removed, the rotation can continue; if not, the rotation is restricted.

[0044] like Figure 2 and Figure 3 As shown, the working process of the cylindrical pipe arrangement device of the present invention includes two working processes: taking out pipes and storing pipes. The taking out pipe working process is to remove the guard plates corresponding to the outer rings of the two pipe slot assemblies 6 in the device at the designated taking out position, and use the existing taking out pipe device 3 or manually take out the pipe column 4 at the designated taking out position, and then the ejection mechanism assembly 8 ejects the inner pipe column 4 to the designated taking out position, and then takes out the ejected pipe column 4 again, and repeats in sequence until the pipe column 4 at that position is emptied, and the encoder transmits a signal to the electric control system, and the electric control system controls the drive motor to drive the pipe arrangement device to rotate, and after the pipe column 4 at the adjacent position is turned to the designated taking out position, the pipe arrangement device stops rotating through the dual recognition of the mechanical positioning assembly 9 and the encoder on the drive motor, and then the outer and inner pipe columns 4 are taken out in sequence, and all the pipe columns 4 in the pipe arrangement device can be taken out by repeating in sequence. The pipe storing process is the reverse process of the taking out process.
